Title: System and method of decomposing fluidic product having particles

Description:
BACKGROUND 
     The present invention relates to a reaction decomposing reactor, and more specifically relates to a subcritical water decomposing reactor for heating and pressurizing aqueous suspension while passing through the reactor. 
     Existing decomposing reactors are used to decompose an aqueous solution having particles into a treated product through one or more chemical reactions. In certain cases, the particles of the aqueous solution include biological materials, such as fiber (e.g., cotton) particles, or in some cases, include organic materials, such as plastic particles. During operation, the aqueous solution in the decomposing reactor is stirred and heated in a reaction vessel for inducing the chemical reactions for the biological materials and/or the organic materials in the aqueous solution. The decomposing reactor produces the treated product through the chemical reactions of the biological materials and/or the organic materials in the aqueous solution. 
     A disadvantage of the existing decomposing reactors is that a reaction level of the aqueous solution may be inconsistent to control the chemical reactions of the particles. Specifically, referring now to  FIG. 1 , an exemplary graphical presentation  10  of a reaction level  12  of the aqueous solution is shown using the existing chemical reactor. In  FIG. 1 , an X-axis represents the reaction level  12  of the aqueous solution, and a Y-axis represents a reaction amount  14  of the aqueous solution. 
     For example, the reaction level  12  refers to a degree of chemical reaction occurred in the aqueous solution having the particles (which turns into the treated product), and the reaction amount  14  refers to a volume or weight amount of the aqueous solution having the particles. As shown in  FIG. 1 , the reaction level  12  of the aqueous solution is not constant relative to the reaction amount  14 . 
     Another disadvantage of the existing decomposing reactors is that precisely determining an optimal reaction level or amount at point  16  can be time consuming, thereby increasing operational expenses. More specifically, although the optimal reaction level and/or amount at point  16 , representing a desired reaction level and/or amount of the aqueous solution, can be achieved using the existing decomposing reactor, an insufficient reaction level at point  18  or an overabundant reaction level at point  20  may also be achieved during decomposition. 
     Such undesired reaction levels and/or amounts at points  18  and  20 , represented on gradually inclining or declining slopes, make it difficult to determine the optimal reaction amount and/or level for the aqueous solution. A proper decomposition of the aqueous solution may not be achieved without precisely determining the optimal reaction amount and/or level. 
     Thus, there is a need to develop an enhanced decomposing reactor that overcomes one or more above-described disadvantages of the existing decomposing reactors.

     DETAILED DESCRIPTION 
     Embodiments of the present disclosure will be described in detail herebelow with reference to the attached drawings. 
     Referring now to  FIG. 2 , an exemplary decomposing system  100  having an induction heating assembly  102  is shown in accordance with embodiments of the present disclosure. In the illustrated embodiment, the decomposing system  100  includes a raw material supply zone  104 , a heating treatment zone  106 , and a treated object retrieving zone  108 . The decomposing system  100  performs a decomposing treatment for converting an aqueous solution  110  having a plurality of particles  112  into a treated product  114  to be stored in the treated object retrieving zone  108  for subsequent retrieval. 
     Exemplary particles  112  include a biological material and/or an organic material. In one example, the biological material can include an agricultural waste, such as cotton, straw, corn, peanut byproducts and the like, and the organic material can include resin, plastic, polymer, polyethylene, polyester, polypropylene, and the like. Other suitable materials, such as inorganic substances, can also be included as the particles  112  to suit the application. 
     Other exemplary particles  112  can include different fiber materials. In one example, the fiber materials include plastic-based fibers, cellulose-based fibers, and/or protein-based fibers. For example, the plastic-based fibers include polyester, nylon, acrylic, and elastane fibers, the cellulose-base fibers include cotton, viscose, lyocell, and bast fibers (e.g., linen, hemp, or jute materials), and the protein-based fibers include wool and silk fibers. 
     The respective zones  104 ,  106 ,  108  can be arranged in the order shown in  FIG. 2 , and respectively treat the successively flowing and passing aqueous solution  110  to be treated by the induction heating assembly  102 . For example, the aqueous solution  110  can be fed through a hollow portion of a pipe body  116  of the induction heating assembly  102 . In one embodiment, the pipe body  116  is made of any suitable metal material, such as stainless steel. 
     In  FIG. 2 , the raw material supply zone  104  includes a tank  118  for storing a proper amount of the aqueous solution  110  to be treated by the induction heating assembly  102 . A feed path  120  formed of a metal pipe (e.g., stainless steel) is connected at one end to the tank  118  and at the other end to the induction heating assembly  102 . A typical example of the tank  118  has a tank capacity of 1000 liters (L), a discharge pressure of 0.1 megapascal (MPa), and a flow rate of 10-40 liter per minute (L/min). However, the tank capacity, the discharge pressure, and the flow rate can vary to suit different applications. A pump  122 , for example, can be connected to the feed path  120  for increasing the discharge pressure of the aqueous solution  110  and for forcibly securing the flow rate of the aqueous solution  110  in the feed path  120 . 
     As shown in  FIG. 2 , the heating treatment zone  106  includes the induction heating assembly  102  having the pipe body  116 . To induce the chemical reaction in the aqueous solution  110 , the induction heating assembly  102  inductively heats the aqueous solution  110  to a predetermined treatment temperature while the aqueous solution  110  is fed in the pipe body  116 . Specifically, the pipe body  116  of the heating treatment zone  106  includes one or more metal pipes  124  functioning as a feed heating kiln body. An exemplary treatment temperature ranges approximately between 100-350 degrees Celsius (° C.). 
     Further, the induction heating assembly  102  includes one or more heating induction coils  126  configured to surround at least a portion of the metal pipes  124 , and a high-frequency power supply unit  128  configured to inductively drive the heating induction coils  126 . In order to use a hollow portion of the metal pipe  124  as a flow path for the aqueous solution  110 , the metal pipe  124  has one end communicating with and connected to a discharge end of the feed path  120  of the raw material supply zone  104 , and is made of stainless steel to be inductively heated by the heating induction coils  126 . 
     A typical inner diameter of each metal pipe  124  is approximately 50 millimeters (mm) or 2 inches and a typical length of each metal pipe  124  is approximately 10 meters. In embodiments, the inner diameter of each metal pipe  124  can range between 2 and 4 inches, and the length of each metal pipe  124  can range between 10 and 80 meters depending on the type of substance of the particles  112  in the aqueous solution  110 . For example, for cotton particles, the length can be about 10 meters, but for plastic particles, the length can be about 50 meters. However, the inner diameter and the length can vary to suit different applications. 
     In one embodiment, an overall length of the metal pipe(s)  124  used in the induction heating assembly  102  is determined based on a predetermined reaction time period associated with the aqueous solution  110 . The predetermined reaction time period may refer to a residence time of the aqueous solution  110  in the induction heating assembly  102  (e.g., see  FIG. 3 , first heating region  138  and/or second heating region  140 ) for obtaining the optimal reaction level and/or amount for the aqueous solution  110  having the particles  112 . 
     In one embodiment, the metal pipe  124  may be disposed with an upward inclination to facilitate a feed of the aqueous solution  110  to be treated. However, in another embodiment, the feed path  120  may be disposed with a downward inclination to facilitate the feed of the aqueous solution  110 . Other suitable arrangements are also contemplated to suit the application. 
     Referring now to  FIGS. 2, 3, and 4 , each heating induction coil  126  is formed by winding an electric conductor, e.g., a copper pipe, and is supported by an insulator  130  so that a substantially constant space is maintained between the heating induction coil  126  and an outer peripheral surface of the metal pipe  124 . A winding pitch of the heating induction coil  126  may be constant or may be varied depending on the application. In one embodiment, the insulator  130  is disposed between the metal pipe  124  and the heating induction coil  126 . 
     The high-frequency power supply unit  128  generates and passes a high-frequency current enough to increase the temperature of the metal pipe  124  to a predetermined treatment temperature, e.g., 100-350° C., for the aqueous solution  110  to be treated using the heating induction coils  126 . An exemplary energization frequency of the high-frequency power supply unit  128  can be approximately 20 kilohertz (KHz) and a maximum output can be approximately 270 kilowatts (KW). However, the frequency and the maximum output of the high-frequency power supply unit  128  can vary to suit different applications. 
     Exemplary arrangements of the metal pipes  124  in the induction heating assembly  102  can be in a horizontal, vertical, or diagonal attitude to suit different applications. However, the diagonal attitude can be selected in consideration of a type of particles  112  and/or the feed of the aqueous solution  110 . For example, as shown in  FIG. 4 , the metal pipe  124  can be preferably installed in an attitude in which a longitudinal axis L of the metal pipe  124  is oriented in a direction angled with respect to a horizontal plane  132  (e.g., a ground surface). 
     An exemplary angle α of the metal pipe  124  ranges approximately between 3 and 30 degrees relative to the horizontal plane  132 . As such, there is a height difference between opposite ends of the metal pipe  124 , and the aqueous solution  110  travels from a lower end of the metal pipe  124  to a higher end of the metal pipe  124 . 
     Returning to  FIGS. 2 and 3 , the heating induction coils  126  of the induction heating assembly  102  includes a first heating induction coil  134  surrounding a first heating region  138  to inductively heat the metal pipe  124  in a temperature rising portion of the induction heating assembly  102 . In the illustrated embodiment, the temperature rising portion is the first heating region  138 . The high-frequency power supply unit  128  is used to inductively drive the first heating induction coil  134 . For example, the high-frequency power supply unit  128  drives the first heating induction coil  134  in the first heating region  138  to increase the temperature of the aqueous solution  110  to the predetermined treatment temperature. 
     Also, the heating induction coils  126  of the induction heating assembly  102  includes a second heating induction coil  136  surrounding a second heating region  140  to inductively heat the metal pipe  124  in a temperature holding portion of the induction heating assembly  102 . In the illustrated embodiment, the temperature holding portion is the second heating region  140 . The high-frequency power supply unit  128  is used to inductively drive the second heating induction coil  136 . 
     For example, the high-frequency power supply unit  128  drives the second heating induction coil  136  in the second heating region  140  to maintain the temperature of the aqueous solution  110  at approximately the same predetermined treatment temperature in the first heating region  138 . 
     More specifically, the second heating induction coil  136  holds the aqueous solution  110  at approximately the same predetermined treatment temperature for a predetermined reaction period while flowing through the temperature holding portion  140 . The predetermined reaction period may refer to a residence time of the aqueous solution  110  in the induction heating assembly  102  for obtaining the optimal reaction level and/or amount for the aqueous solution  110  having the particles  112 . In one embodiment, an overall length of the metal pipe(s)  124  used in the temperature holding portion  140  is determined based on the predetermined reaction period. 
     In another embodiment, the high-frequency power supply unit  128  drives the second heating induction coil  136  to increase the temperature of the aqueous solution in the metal pipe  124  in the temperature holding portion  140  to a second predetermined temperature (e.g., 250° C.) that is higher than a first predetermined temperature (e.g., 200° C.). In one example, the first predetermined temperature is the temperature of the aqueous solution  110  in the metal pipe  124  in the temperature rising portion  138 . 
     In some embodiment, the pipe body  116  of the heating treatment zone  106  includes a first refrigerant passage  150  ( FIG. 2 ) configured for cooling the first heating induction coil  134  using the first refrigerant passage  150  associated with the temperature rising portion  138 . Similarly, the pipe body  116  of the heating treatment zone  106  includes a second refrigerant passage  152  ( FIG. 2 ) configured for cooling the second heating induction coil  136  using the second refrigerant passage  152  associated with the temperature holding portion  140 . 
     In embodiments, the first heating induction coil  134  is applied with a first predetermined electric power, and the second heating induction coil  136  is applied with a second predetermined electric power, wherein the second predetermined electric power is lower than the first predetermined electric power. For example, the first predetermined electric power can be approximately 100 KW and the second predetermined electric power can be approximately 5 KW. Other suitable amounts of electric power can be applied to suit different applications. 
     In embodiments, the predetermined reaction period can be varied based on a type of substance in the particles  112 . For example, when the type of substance in the particles  112  is a biological material, such as cotton particles, the predetermined reaction period can be approximately one (1) minute. In another example, when the type of substance in the particles  112  is an organic material, such as plastic particles, the predetermined reaction period can be approximately forty (40) minutes. 
     During the predetermined reaction period, the aqueous solution  110  having the particles  112  is decomposed while flowing through the temperature rising portion  138  and the temperature holding portion  140  to obtain the optimal reaction level and/or amount for the particles  112 . For example, unlike the existing decomposing reactors, in the present disclosure, the reaction level of the aqueous solution  110  is constant relative to the reaction amount. Detailed descriptions of the reaction level and amount of the present disclosure are provided below in paragraphs relating to  FIG. 5 . 
     In embodiments, one or more metal pipes  124  are included in the temperature rising portion  138 , and similarly one or more metal pipes  124  are included in the temperature holding portion  140 . Although a single metal pipe  124  is shown in the temperature rising portion  138  and the temperature holding portion  140  in  FIG. 3 , a plurality of metal pipes  124  connected in parallel can also be used to increase a heat transfer area and a flow rate in the temperature rising portion  138  and/or the temperature holding portion  140 . In certain embodiments, the metal pipes  124  in the temperature rising portion  138  are positioned lower than the metal pipes  124  in the temperature holding portion  140 . 
     Further, in other embodiments, at least one metal pipe  124  is seamlessly connected between the temperature rising portion  138  and the temperature holding portion  140 . For example, as shown in  FIG. 3 , at least one seamless bending region  142  of the metal pipe  124  is included between the temperature rising portion  138  and the temperature holding portion  140 . In another embodiment, at least one seamless bending region  142  of the metal pipe  124  is included in the temperature holding portion  140 . Similarly, at least one seamless bending region  142  of the metal pipe  124  can be included in the temperature rising portion  138 . Any combinations of the seamless bending regions  142  in the temperature rising portion  138  and/or the temperature holding portion  140  are contemplated to suit the application. 
     Referring now to  FIG. 5 , the induction heating assembly  102  provides the reaction level of the aqueous solution  110  that is consistent for the proper chemical reactions for the particles  112 . In  FIG. 5 , an exemplary graphical presentation  30  of the reaction level and amount of the aqueous solution  110  is shown when using the induction heating assembly  102 . In  FIG. 5 , an X-axis represents a reaction level  32  of the aqueous solution  110 , and a Y-axis represents a reaction amount  34  of the aqueous solution  110 . 
     For example, the reaction level  32  refers to a degree of chemical reaction occurred in the aqueous solution  110  (which turns into the treated product  114 ), and the reaction amount  34  refers to a volume or weight amount of the aqueous solution  110 . As shown in  FIG. 5 , the reaction level  32  of the aqueous solution  110  is constant relative to the reaction amount  34 . 
     In embodiments, each metal pipe  124  has a constant cross section configuration which causes a substantially constant reaction amount for the aqueous solution  110 . In the illustrated embodiment, since only a combination of metal pipes  124  is used for high pressure piping, it is much easier and cheaper to manufacture the induction heating assembly  102  than the existing decomposing reactors. 
     Further, an optimal reaction amount at point  36 , having a desired reaction level of the aqueous solution  110  can be readily achieved using the induction heating assembly  102 . An insufficient reaction level at point  38  or an overabundant reaction level at point  40  can be readily distinguished from the desired reaction level  36  during decomposition of the particles  112 . As such, the present disclosure reduces operational time and related expenses. 
     Referring now to  FIG. 6 , in some embodiments, the hollow portion of each metal pipe  124  can include one or more lumens  144  for delivering the aqueous solution  110 . In one embodiment, the aqueous solution  110  having the plurality of particles  112  can be delivered in the temperature rising portion  138  using a static mixer  146  mounted in at least one lumen  144  of the hollow portion of the metal pipe  124 . 
     In embodiments, adjacent metal pipes  124  are connected using connecting members  148  disposed at opposite ends of each metal pipe  124 . For example, the connecting member  148  can be connected and tightened using one or more fasteners and corresponding nuts (not shown). 
     In some embodiments, a screw feeder, such as the static mixer  146  shown in  FIG. 6 , can be mounted in the hollow portion of the metal pipe  124 . Other suitable static mixers can be used to suit different applications. In some embodiments, a flow rate of the aqueous solution  110  can be pulsated in at least one of: the temperature rising portion  138  and the temperature holding portion  140  to avoid unwanted settlement of the particles  112  in the metal pipe  124 . In one embodiment, a control system  154  ( FIG. 2 ) communicably connected to the pump  122  via a network  156  ( FIG. 2 ) instructs the pump  122  to pulsate a power output of the pump  122  such that the flow rate of the aqueous solution  110  in the metal pipe  124  is varied. 
     In embodiments, the flow rate of the aqueous solution  110  can be pulsated in any portion of the metal pipe  124 . The settlement of the particles  112  in the metal pipe  124 , known as suspension, may cause an undesired decomposition result. Thus, the flow rate of the aqueous solution  110  in the metal pipe  124  can be set to a predetermined flow rate at which the suspension of the particles  112  does not precipitate. 
     In one embodiment, the static mixer  146  is inserted into the lumen  144  of the hollow portion of the metal pipe  124  to create the internal turbulent flow in the seamless bending region  142 . Although one or more stirring blades, e.g., with the static mixers  146 , can be used to stir or mix the aqueous solution in the metal pipe  124  during operation, the seamless bending region  142  of the metal pipe  124  can be specifically configured to create an internal turbulent flow in the seamless bending region  142 . 
     Referring now to  FIGS. 3 and 7 , in embodiments, the seamless bending region  142  has an elbowless portion between the temperature rising portion  138  and the temperature holding portion  140 . In some embodiment, the seamless bending region  142  can have the elbowless portion in the temperature rising portion  138  and/or the temperature holding portion  140 . 
     The elbowless portion may refer to a connection area between two adjacent metal pipes  124  without using any elbow or sleeve connector. For example, the elbowless portion is created by inductively heating and bending the metal pipe  124 . In embodiments, the seamless bending region  142  is included in the temperature rising portion  138  and/or the temperature holding portion  140 . 
     As shown in  FIG. 7 , in some embodiments, the seamless bending region  142  has a bending diameter R 1  that is greater than an inner diameter R 2  of the metal pipe  124  and up to three (3) times larger than the inner diameter R 2  of the metal pipe  124 . For example, the bending diameter R 1  is defined by at least a portion of a central longitudinal axis C of the metal pipe  124  in the seamless bending region  142 . An exemplary mathematical relation between R 1  and R 2  is shown below in expression (1): 
         R 2&lt; R 1≤3* R 2  (1)
 
     In this configuration, the internal turbulent flow is automatically generated within the metal pipe  124  in the seamless bending region  142  due to a current flow rate of the aqueous solution  110  in the metal pipe  124 . A cross-sectional area and a flow velocity of the metal pipe  124  can vary based on the current flow rate of the aqueous solution  110  and/or the type of substance in the particles  112 . During operation, the illustrated configuration provides the internal turbulent flow that causes a high-speed flow of the aqueous solution  110  in the metal pipe  124  to avoid clogging and also prevent unwanted precipitation or settlement of the particles  112  in the induction heating assembly  102 . 
     In embodiments, the seamless bending region  142  includes a first bent portion  142 A, a second bent portion  142 B, and a straight portion  142 C. Specifically, the first bent portion  142 A and the second bent portion  142 B are created by inductively heating and bending the metal pipe  124  such that the straight portion  142 C is disposed between the first bent portion  142 A and the second bent portion  142 B. 
     As such, the first bent portion  142 A, the straight portion  142 C, and the second bent portion  142 B are sequentially and seamlessly connected with one another without using any elbow or sleeve connector(s). At least one of the first bent portion  142 A and the second bent portion  142 B has the bending diameter R 1  that is greater than the inner diameter R 2  of the metal pipe  124  and up to three (3) times larger than the inner diameter R 2  of the metal pipe  124 . 
     In embodiments, each metal pipe  124  includes a first straight portion having a first predetermined length L 1 , a second straight portion having a second predetermined length L 2 , and a third straight portion having a third predetermined length L 3 . In the illustrated embodiment, L 1  is longer than L 2 , and L 2  is longer than L 3 . For example, L 2  can be the straight portion  142 C of the seamless bending region  142 . In another embodiment, L 1  is longer than L 2  and L 3 , and L 3  is longer than L 2 . Other suitable arrangements are also contemplated to suit the application. Exemplary mathematical relations between L 1 , L 2 , and L 3  are shown below in expression (2):

     Referring now to  FIG. 8 , a flow chart of an exemplary method  200  of decomposing a fluidic product, such as the aqueous solution  110 , having a plurality of particles, such as the particles  112 , in accordance with embodiments of the present disclosure. The method  200  is shown in relation to  FIGS. 1-7 . 
     The method  200  can be implemented by the control system  154  ( FIG. 2 ) communicably connected to the induction heating assembly  102  via the network  156 . In one embodiment, the steps implementing the method  200  may be in the form of computer readable program instructions stored in one of memories of electronic controllers in the control system  154  and executed by a respective processor of the electronic controllers, or other computer usable medium. 
     In another embodiment, the steps implementing the method  200  may be stored and executed on a module or controller, such as the control system  154 , which may or may not be independent from one of the electronic controllers of the decomposing system  100 . The method  200  may run continuously or may be initiated in response to one or more predetermined events, such as an initial push of a start button (not shown). Any steps of the method  200  can be executed in any order suitable for the application. 
     The method  200  begins in step  202 . In step  204 , the control system  154  instructs the first heating induction coil  134  to inductively heat the aqueous solution  110  at a first predetermined temperature (e.g., 200° C.) while flowing through the temperature rising portion  138 . As shown in  FIG. 3 , the temperature rising portion  138  has a first heating region formed of at least one metal pipe  124  in such a manner that a hollow portion of the metal pipe  124  functions as a flow path for the aqueous solution  110 . 
     In step  206 , the control system  154  instructs the first heating induction coil  134  to inductively heat the temperature rising portion  138 . In one embodiment, the first heating induction coil  134  surrounds the first heating region of the temperature rising portion  138  to inductively heat the temperature rising portion  138  using the high-frequency power supply unit  128  for driving the first heating induction coil  134 . 
     In step  208 , the control system  154  instructs the second heating induction coil  136  to hold or maintain the temperature of the aqueous solution  110  at approximately the first predetermined temperature (e.g., 200° C.) for a predetermined reaction period (e.g., 5 minutes) while flowing through the temperature holding portion  140 . As shown in  FIG. 3 , the temperature holding portion  140  has a second heating region formed of at least one metal pipe  124  in such a manner that the hollow portion of the metal pipe  124  functions as the flow path for the aqueous solution  110 . 
     In step  210 , the control system  154  instructs the second heating induction coil  136  to inductively heat the temperature holding portion  140 . In one embodiment, the second heating induction coil  136  surrounds the second heating region of the temperature holding portion  140  to inductively heat the temperature holding portion  140  using the high-frequency power supply unit  128  for driving the second heating induction coil  136 . 
     In step  212 , the control system  154  instructs the second heating induction coil  136  to continuously or intermittently perform the heating in the temperature holding portion  140  to maintain the first predetermined temperature for the predetermined reaction period to achieve proper decomposition of the particles  112  in the aqueous solution  110 . In one embodiment, the particles  112  are flowing through the temperature rising portion  138  and the temperature holding portion  140  during the predetermined reaction period. 
     The method  200  ends in step  214  and control may return to step  202 . One or more of steps  204 - 212  can be repeated as desired. 
     It should be appreciated that any steps of the method  200  described herein may be implemented by a process controller, or other similar component, of the control system  154 . Specifically, the process controller may be configured to execute computer readable instructions for performing one or more steps of the method  200 . In one embodiment, the process controller may also be configured to transition from an operating state, during which a larger number of operations are performed, to a sleep state, in which a limited number of operations are performed, thus further reducing quiescent power draw of an electrical power source for the decomposing system  100 .
