Please select the most similar patent number from A, B, C and D. Which number is?
Disclosed are an ultraviolet lamp disinfection water purification reactor and a fabrication method therefor, the reactor comprising a reactor cavity, which is provided with a water inlet and a water outlet; an ultraviolet disinfection lamp is disposed within the reactor cavity; a rectifying device is disposed within the reactor cavity, and rectifying through holes are distributed on the rectifying device. By using a design in which a rectifying device cooperates with a ultraviolet disinfection lamp, water flow has a rectifying effect after passing through rectifying through holes of the rectifying device, such that turbulence or eddy currents may be effectively reduced, and a better purification and disinfection effect can be achieved by means of ultraviolet disinfection.
A: Provided is a disposable bioreactor comprising a reactor chamber and a connected pipe. The connected pipe is arranged on the top of the reactor chamber. The reactor chamber is composed of more than two pieces of chamber walls connected via fusion or adhesion, and comprises an intersection part, and at least one hollow arm part communicated with the connected pipe via the intersection part. The tail end of said hollow arm part is sealed. Driven by a rocking table, liquid in the reactor chamber can flow along a long shaft of the disposable bioreactor, so as to produce wave and turbulent mix, and mixing and mass transfer efficiency is increased greatly.
B: Disclosed is a flow-through sterilization device, comprising a housing having a water inlet and a water outlet, and a sterilization cylinder disposed inside the housing. An LED lamp assembly is provided at the bottom of the sterilization cylinder; the LED lamp assembly and the sterilization cylinder enclose a sterilization cavity; a reflector is provided at the top of the sterilization cavity; a water flow passage is formed between the housing and the sterilization cylinder; and the water inlet, the water flow passage, the sterilization cavity, and the water outlet are connected in sequence. The deep ultraviolet light emitted by the LED lamp assembly is incident into the sterilization cavity to sterilize the water flowing through the sterilization cavity; and the reflector reflect the deep ultraviolet light in the sterilization cavity, so that the deep ultraviolet light can repeatedly act on the water flow to further enhance the sterilization effect on the water flow. In addition, the reflector disposed on the top of the sterilization cavity can reflect the deep ultraviolet light downward into the sterilization cavity, such that dead corners in the sterilization cavity can be effectively sterilized.
C: A water tank and a dishwasher. The water tank comprises: a water tank chamber (b901); a salt feeding port (b10) arranged on a side wall of the water tank chamber (b901), and located at the downstream of a water tank water inlet (b7); and a flow rectification structure arranged on an inner wall of the water tank chamber (b901), and comprising at least one rib, the rib being located on a flowing path of salt and located at the upstream of a water tank water outlet (b8). Water flow bypasses the flow rectification structure and forms at least one bypassing path. Salt or a salt solution is fed into the water tank chamber (b901) by means of the salt feeding port (b10), and then is performed an electrolysis reaction to prepare disinfecting water. While the disinfecting water is used to disinfect tableware in the dishwasher, a pipeline through which the disinfecting water flows is also disinfected and sterilized. A certain time is required for dissolving salt in water, and the flow rectification structure is used to intercept salt blocks on the path where salt flows to the water outlet, so that the salt blocks are impacted and dispersed or the time for the salt to reach the water outlet is prolonged.
D: An ultraviolet disinfection lamp, comprising a lamp holder (1) and a lampshade (2) connected to each other, and a plurality of ultraviolet lamp tubes (3) provided in the lampshade (2). The end of the lamp holder (1) connected to the lampshade (2) is provided with a protrusion (4). A communication hole (10) communicating with the interior of the lamp holder (1) is provided in the protrusion (4). A plurality of positioning holes (5) are arranged on the protrusion (4) around the circumference of the communication hole (10). The end of the lampshade (2) connected to the lamp holder (1) is provided with a bottom cover (6) covering the protrusion (4). The bottom cover (6) is provided with a first through hole (12) correspondingly communicating the communication hole (10) and a plurality of penetrating holes (7) correspondingly communicating with the positioning holes (5). The ultraviolet lamp tubes (3) extend into the lamp holder (1) through the first through hole (12) and the communication hole (10). The bottom cover (6) is provided with a plurality of support rods (8) arranged around the ultraviolet lamp tubes (3). One end of the support rods (8) extends into the positioning holes (5) through the penetrating holes (7) and is connected to the protrusion (4), and the other end is connected to a top cover (9) covering the tops of the ultraviolet lamp tubes (3). The end of the top cover (9) facing the ultraviolet lamp tubes (3) is provided with a protective ring (11) disposed around the ultraviolet lamp tubes (3). According to the ultraviolet disinfection lamp, the lampshade is easy to install, the bulb replacement is very convenient, and the overall structure of the lamp is simple.
