## Background
FIELD OF THE INVENTION
The present invention relates to an energy converter that makes use of a jet to generate shockwaves, especially to a fluid shockwave reactor that carries out an ultrafine crush treatment for fluid materials, or realizes catalytic treatment for chemical reactions of liquid materials.
BACKGROUND OF THE INVENTION
In the field of modern industrial production, mechanical equipments for carrying out an ultrafine crush treatment for fluid materials have been widely used, such as high pressure jet collision pulverizers, high pressure target jet pulverizers, high pressure homogenizers, etc. At present, in order to achieve ultrafine crushing effect of fluid materials, this type of equipment needs working pressure as high as 100-200 MPa or even higher. The dependence on an ultra high pressure leads to high energy consumptions in industrial productions, strict requirements on the equipment structure and equipment performance, high requirements on the particle size of fluid materials, and low levels of safety in industrial productions. The main problem within these devices lies in imperfection of their core structures. Part of the energy is released in void during processing, and therefore the crushing efficiency is reduced. As a result, without ultra-high voltage power, the ultrafine crushing effect of fluid materials can hardly be reached.
SUMMARY OF THE INVENTION
The fluid shockwave reactor according to the present invention, based on high pressure fluid crushing technology of all kinds in domestic and abroad, focused on the improvement of energy conversion efficiency, through innovative design of the core structure, has led to a highly efficient, energy saving converter.
This fluid shockwave reactor introduces laser resonance theory into fluid physics, by using the shockwave resonance energy concentration device, enhances the intensity of the shockwave produced in jet impinging process, strengthens the effect of ultrahigh pressure and cavitation in a shockwave field, and intensifies the physical and chemical effects on the treated materials. Mass number of tests and production practices have proved that, compared to various types of fluid shockwave crushers that rely on superhigh pressure, this new fluid shockwave reactor can achieve ultrafine crushing of fluid materials with lower energy consumption. Under certain conditions, this fluid shockwave reactor may also effectively catalytize the chemical reaction of fluid materials.
The present invention has broad applications in energy industry, chemical industry, building materials, food, medicine and other manufacturing areas.
The technical solution of the present invention is described as follows: The fluid shockwave reactor consists of a shockwave resonance energy concentration device and at least one set of jet collision device. The jet collision device is composed of two sets of coaxial and opposite nozzle parts, each of which has the same nozzle. The shockwave resonance energy concentration device is a chamber combined with rigid spherical concave surfaces or other rigid convergent surfaces which are able to reunite the shockwaves emitted from a focus and converge them back to the focus to produce new shockwaves. This chamber has a jet orifice (201, in FIGS. 1-3) that holds the nozzle parts and a discharge port that permits outflow of the processed fluid from the chamber. A mid-point between the two nozzles is the location where jet collisions occur, and is disposed at the center of the spherical concave surfaces or the focus of all combined convergent surfaces. The sum of the cross-sectional area of the discharge port is much greater than the total cross-sectional area of all of the nozzles, and the cross-sectional area of the discharge port and the position where the discharged port is placed can keep fulfillment of the processed fluid materials within the chamber when the fluid shockwave reactor is at work.
For example, the ratio between the sum of the cross-sectional area of the discharge port and the total cross-sectional area of all of the nozzles could be 10:1, 100:1, or 1000:1 so as to form enough pressure drop when a high pressure fluid injects through the nozzles, and therefore the jet is accelerated sufficiently.
The aforementioned combined convergent surfaces include at least one convergent concave surface, and can also include reflection plane(s) or convex surface(s). The concave surface can be a parabolic or spherical concave surface. In the description, the technical feature “a chamber combined with rigid spherical concave surfaces or other rigid convergent surfaces which are able to reunite the shockwaves emitted from a focus and converge them back to the focus to produce new shockwaves” may include other subordinate parts which do not participate convergent reflections in producing shockwaves but play a supporting role in making it “keep fulfillment of the processed fluid materials within the chamber when the fluid shockwave reactor is at work” as components of the chamber wall except for rigid spherical concave surfaces or other rigid convergent surfaces which are able to reunite the shockwaves emitted from a focus and converge them back to the focus to produce new shockwaves”.
Beneficial effects of the fluid shockwave reactor are as follows: The fluid shockwave reactor according to the present invention, focused on flowing characteristics of fluid, takes the optical resonator principle as reference and is designed a chamber structure of the fluid shockwaves. This resonant chamber structure can gather the shockwave energy produced by strong turbulence when opposite jets collide, through reflection and aggregation caused by confocal reflection chamber with different radius of curvature and intervals or caused by reflective chamber with concentric spherical concave. The turbulent area around the chamber structure forced the energy density within the shockwave radiation field raised enormously, and the materials passing through the chamber are stimulated by chamber resonance and in turn materials are ultrafine crushed. Under the condition of same power input, compared with the ordinary jet collision device, the resonant chamber structure can effectively improve the efficiency of conversion, greatly improve the treatment effect. Besides ultrafine crushing of fluid material, this fluid shockwave reactor can also play a catalytic role in the chemical reaction process of liquid materials.

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1-2, take the spherical indentation as a reflection surface of the shockwave resonance energy concentration device as an example, the operational principles of the fluid shockwave reactor are as follows: A fluid which has passed through the high pressure pump flows out from two nozzles 1 at a speed of hundreds m/sec or even km/sec and collides at the connection middle point, and in turn results in self-excited vibration and then forms shockwaves. As the fluid changes its movement direction, it forms a disc-shaped scattering jet having a center located at the collision point, and eventually flows out of the chamber through a discharge port. The shockwaves diffuse outwardly in the fluid filled in the chamber, relect when reaching the chamber wall formed by a rigid ball indentation 2, reunite and strengthen at a focus position, and then overlap with the primary waves produced there. This process recycles to form oscillatory waves. Under a relatively stable jet pressure, the shockwaves continuously strengthen, thereby forming a very strong resonance shockwaves. The strong resonant shockwaves alter between instantaneous high pressures and cavitation effects, which in turn has strong physical and chemical effect on the fluid material therein. When dealing with the fluid material, this is the exact reason why the fluid shockwave reactor shows better physical and chemical effect than pure jet collision device generally does.
Based on different application examples of the device, the pressures imposed by the high-pressure pump usually ranges between 5-100 MPa, commonly ranges between 1 to 30 MPa.
As shown in FIG. 3, when the fluid shockwave reactor is provided with more than one jet collision devices, its nozzles can be distributed in one plane, or in a space, but the positions of the nozzles should avoid the locations of the disc-shaped scattering jets generated by other colliding jets, namely the nozzle axes are not vertical to each other, otherwise interference between the jet flows and scattering flows will reduce the reaction effect.
According to the principle of laser resonator, it is possible to generate waves from one point and then converge them to the point so as to form a concave surface of shockwaves or combinations of concave surfaces, such as a spherical concave surface, two opposite paraboloids which are confocal and coaxial, and some curved surface combinations which include at least one convergence concave surface and combinations of flat surfaces and convex surfaces. For spherical reflection concave surfaces, the waves emitted from the center converge back there after one reflection. For two opposite paraboloids which are confocal and coaxial, waves emitted from the confocal converge back there after two reflections. For the curved surface combinations having flat surfaces and convex surfaces, due to the limitation of fluid and the complexity of structure, it belongs to a secondary or unfavorable plan in the present invention, and no further discussion herein.
Since the fluid within the chamber stays in a flow state when the fluid shockwave reactor is at work, the propagation direction of the wave is, in a certain extent, affected by the flow of medium. Therefore, there could be a deviation between the best focal point after the shockwave reflection and the geometric focus of the convergence concave, and the shockwave resonance device of the reactor shall have a certain shape for making adjustment in an extent, i.e., its shape slightly deviates from a standard spherical concave surface or paraboloid, but still called as spherical concave surface and paraboloid.
The aforementioned fluid, fluid material or processed fluid can be a continuous phase of a liquid material, and can also be a continuous phase of a gas material, the only point being that shockwaves differ in gas medium and liquid medium with respect to energy transfer efficiency and physical and chemical effect. Therefore, if not specified otherwise, fluid, fluid material or processed fluid refer to a continuous phase of a fluid material, as follows.
The present invention is further explained with reference to the following preferred embodiments.

To make high pressure sealed nozzle components and curved reflection chamber, high-strength wear-resisting ceramics is preferred.
The operation principle of the shockwave reactor with multi-sets of collision jet is as follows:
The fluid material provided by fluid power equipment under a certain pressure, goes through a feeding channel into the vortex-type feeding chamber, and then into the slotted self-servo diversion chamber, deliveries to an accelerate channel continuously and evenly, and at last forms a jet at high speed and enters into the inner chamber of the fluid shockwave reactor. When multiple high-speed jet beams collide in the reactor, and form intense turbulent jets, strong self-excited vibrations and shockwaves are produced. The geometric structure of the reflection wall inside the resonant chamber can accumulate energy, and build a vibration system with the resonant chamber structure. In this process, the fluid is not only a vibration body that produces vibrations, but also a carrier that transmits vibrating waves; the fluid medium is stimulated to generate shockwaves. When the relative velocity of the jet beams, the reflection wall radius of the resonant chamber of the fluid shockwave reactor, and the length of the chamber, are harmonized with the frequency of the shockwaves, these waves will create repeated shocks between the reflection walls of the resonant chamber, the amplitude of the shockwaves will increase incessantly. When the shockwaves reach a certain energy intensity and frequency close to the resonant frequency of the fluid material in the reactor, resonance of the fluid happens. As a result, the solid particles of the fluid entered into the fluid shockwave reactor undergo crushing effects such as fluid substances in solid particles into the fluid besides shear force crushing effects; its nucleus structure can be broken by the shockwaves. Shockwave energy can even crack links between molecules of molecular mass within the fluid material. The multiple energy amplification process, can realize the ultrafine crushing of fluid material. Meanwhile with the occurrence of catalytic conditions such as rapid heating, high frequency resonance, high-speed collision and shearing, under certain technological conditions, the fluid can undergo physical and chemical changes instantly during the same process.
The features and the beneficial effects of the shockwave reactor with multi-sets collision jet are listed as follows:
1. By using a symmetric confocal coupled resonant chamber, the reactor adjusts symmetrical torque frequency tuner for tuning and forming the shockwave radiation field.
2. In order to retrieve a higher flow collision speed, it is required to retain a certain distance between the nozzle distance and the nozzle aperture diameter. As regards the shockwave reactor with a single set collision jet, in order to improve working efficiency and increase working flow rate, it is necessary to enlarge the nozzle aperture diameter, and thus increase the distance between the nozzles. The chamber volume shares a direct ratio with three times of the nozzle distance. Increased distance between the nozzles must cause considerable enlargement of the resonant chamber, and a huge increase of affecting space of shockwaves, resulting in serious energy dispersion and reduced efficiency. The multi-sets collision jets, however, can decrease the size of each pair of jet nozzles, and thus increase working flow rate of the device within limited space, and improve the efficiency of the single equipment.
3. Directing at different materials, different processing technologies, and different working flow rates, one can adopt high pressure sealing nozzle components with different nozzle numbers, nozzle aperture diameters, etc., and reflection chambers having different focal lengths.
4. The vortex-type feeding chamber is used in this example, it can divert the feeding fluid along the inner walls of the reactor, overcome the chaotic turbulence in the feeding chamber, solve uneven feeding or congestion problem caused by accumulation of the fluid material formed by slow flowrate.
5. Slotted self-servo diversion chamber is used in this example, it can restrict particles bigger than the given diameter of jet channel from entering into the diversion chamber, overcome the fluid channel congestion problem. The inner wall of the chamber with symmetrical curves, capable of keeping steady flows, can smooth the fluid material, and make it enter the acceleration passage evenly and in order.
6. The symmetric coupled deceleration passage is used in this example, it guides the fluid material crushed in the resonant chamber. The fluid propelled with vibration by continuous material coming into the chamber; it flows orderly into the pressure deduction chamber following symmetric coupled deceleration passage. This function can effectively reduce the disturbance effect of this part fluid material on the inward jet beams within the chamber and on the reflected jets in the reflection chamber, so as to ensure stable working condition in the reactor chamber.
The applications of the fluid shockwave reactor according to the present invention are listed below:
1. Experiment to Improve the Solubility of Nimodipine in Alcohol
To a medical fluid shockwave reactor with a power of 15 kw/h, a flow rate of 2.5 m3/h is employed to treat Nimodipine and alcohol mixture under a pressure of 20 MPa. Compared with the comparative sample, solubility of Nimodipine in alcohol increases more than 195 times or above. Therefore, to dissolve the same dose, the amount of alcohol can be reduced greatly. This can effectively control the physiological stimulation when using this kind of antihypertensive drugs.

After a first level treatment, the coal granular of feeding slurry at −700 μm with an average particle size at 64 μm is decreased to the granular of the ultrafine slurry at −200 μm with an average particle size at 64 μm. Compared with the conventional coal water slurry production technology, this device can produce ultrafine coal water slurry under a relatively low energy consumption. If it is used to produce ordinary coal water slurry, then the energy consumption could be saved by 30% and above, and the technical specifications such as rheological property and stability of the coal water slurry, are improved greatly.
4. Amelioration on Mellowing Process of Liquor Products

Compared with comparative samples, the molecular group of liquor turned smaller after the treatment of the fluid shockwave reactor (Oxygen 17 of nuclear magnetic resonance: 90 Hz in original samples, and 59 Hz after treatment). Therefore, this process can effectively improve the activity of water molecules and ethanol molecules, improve their degree of association. The catalytic condition in the process has the volatilization effect on acrolein, hydrogen sulfide, etc., in the liquor. The fermentation process generally requires several months or even years to finish the microscopic chemical reaction, and can be reached instantaneously in this treatment. For the treated liquor, alcohol content is constant, the color is glittering, the aroma is pure and strong, and taste is soft and fruity.
