[0001] Cross-reference to related applications

[0002] This application claims the benefit of Chinese Patent Application No. 202410811323.2, filed on June 21, 2024, the contents of which are incorporated herein by reference. Technical Field

[0003] This application pertains to fluid mixing technology, specifically to fluid mixing devices. Background Technology

[0004] As the name suggests, fluid mixing devices are used to mix two or more different fluids, especially immiscible fluids, such as immiscible gases and liquids, or two immiscible liquids. The working principle of fluid mixing devices is usually based on physical or chemical methods. Through specific design structures and operating parameters, they achieve the desired mixing effect between two immiscible fluids during the mixing process. For example, by using a fluid mixing device with a microparticle function to microparticle the fluid acting as the solute, the mixing effect between the two fluids can be improved in several ways, such as increasing the contact area at the two-phase interface, reducing the solute diffusion distance, and increasing the reaction rate.

[0005] Traditional techniques often employ spraying, ultrasonic waves, and stirring to atomize fluids, thereby accelerating the mixing process. Currently, newer atomization technologies and equipment, such as Venturi jets and dissolved air pumps, are increasingly used. However, current technology still struggles to achieve fluid atomization under low-speed, low-pressure conditions, requiring high-power, high-lift water pumps to generate high-speed water flow to compress and cut liquids or gases. While this method produces smaller droplets or bubbles with high mass transfer efficiency, it consumes a great deal of power and is costly, thus limiting the application and widespread adoption of fluid atomization in fluid mixing operations.

[0020] In some embodiments, the fluid mixing device includes a propulsion mechanism, which includes a liquid pump and a jet structure connected to the discharge end of the liquid pump. The jet structure is provided with a spray nozzle, and the propulsion mechanism can drive liquid from the spray nozzle toward the top of the plurality of microporous tubes via the liquid pump.

[0021] In some embodiments, the jet structure includes a jet pipe located above the plurality of microporous tubes and arranged laterally, the two ends of the jet pipe being closed, the jet pipe having the liquid injection port and the liquid inlet communicating with the liquid discharge end of the liquid pump on the pipe wall, the liquid injection port being provided from one end of the jet pipe to the other end.

[0022] In some embodiments, the fluid mixing device includes:

[0025] In some embodiments, the annular elastic element is an annular spring.

[0026] In some embodiments, the gas release assembly includes:

[0027] The gas release plate is formed as a microporous plate;

[0028] The bottom plate is connected vertically to the gas release plate to define a gas release chamber, and the bottom plate is provided with an air inlet that communicates with the gas release chamber.

Furthermore, vibration cutting produces bubbles or liquid particles with smaller diameters than non-vibration cutting. By controlling the inflow rate and vibration frequency, micro / nano-sized bubbles or liquid particles can be generated.

Detailed Implementation

[0045] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0046] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0047] As shown in Figures 1 to 4, an exemplary embodiment of this application provides a fluid mixing device that can be disposed entirely below the surface of a liquid serving as a solvent, and can micronize a gas or another liquid serving as a solute to form micro-nano-scale bubbles or liquid particles, thereby mixing them with the liquid serving as a solvent.

[0048] Specifically, the fluid mixing device includes a main support 1, a movable support, multiple microporous tubes 2, a vibration mechanism 3, and a flow-pushing mechanism. The microporous tubes 2 are tubular structures with micropores on their walls. The movable support is movably connected to the main support 1 and has an inlet structure 6 for the flow of fluid as a solute. The multiple microporous tubes 2 are arranged on the movable support and communicate with the inlet structure 6, allowing the fluid as a solute to enter the microporous tubes 2 through the inlet structure 6 and exit from the micropores of the microporous tubes 2, forming micro / nano-scale bubbles or liquid particles. The vibration mechanism 3 includes a vibration device 301 connected to the movable support to drive the multiple microporous tubes 2 to vibrate. The flow-pushing mechanism includes a liquid pump 4 and a jet structure 5 communicating with the discharge end of the liquid pump 4. The jet structure 5 has a spray nozzle 501. The flow-pushing mechanism can drive the liquid as a solvent through the liquid pump 4, causing it to be sprayed from the spray nozzle 501 upwards towards the multiple microporous tubes 2.

[0049] Therefore, the fluid mixing device of this exemplary embodiment can be integrally disposed in the liquid as a solvent. During the mixing operation, high-pressure gas as a solute or another liquid is introduced into multiple microporous tubes 2 through the inlet structure 6, and the movable support is driven to move back and forth by the vibration mechanism 3 to drive the microporous tubes 2 to vibrate at high frequency, thereby generating micro-nano-scale bubbles or liquid particles, and causing the micro-nano-scale bubbles or liquid particles to detach from the corresponding microporous tubes 2 to mix into the liquid as a solvent, thereby achieving the ideal mixing effect.

[0050] During the above process, due to the adsorption force of the microporous tube 2 material, bubbles or liquid particles discharged from the micropores may be unable to detach from the microporous tube 2. Therefore, under the vibration intervention of the vibration mechanism 3, the microporous tube 2 and the liquid serving as the solvent can generate high-speed relative motion. The liquid cuts the bubbles or liquid particles that have just exited the microporous tube 2, thereby overcoming the adsorption force of the microporous tube 2 on the bubbles or liquid particles. This eliminates the need to rely on the buoyancy of the bubbles or liquid particles themselves, allowing them to mix into the liquid as a solvent while still in a micro-nano scale. Vibration cutting produces bubbles or liquid particles with smaller particle sizes than non-vibration cutting. In practical applications, by controlling the inflow rate and vibration frequency, micro-nano scale bubbles or liquid particles can be produced.

[0051] Crucially, the work done by the vibration mechanism 3 is solely for driving the movable support and multiple microporous tubes 2 to vibrate and overcome the frictional resistance of the liquid. Compared to existing methods that use high-lift water pumps to generate high-speed water flow to squeeze and cut the liquid or gas as a solute, this significantly reduces operational energy consumption, thereby effectively saving operating costs. On the other hand, the fluid mixing device of this exemplary embodiment can also utilize a propulsion mechanism to pressurize the liquid as a solvent, causing it to be sprayed upwards towards the multiple microporous tubes 2, forming a liquid flow with a certain velocity. This liquid flow pushes newly formed microbubbles or liquid particles away from the microporous tubes 2, suspending the pushed-away bubbles or liquid particles in the liquid as a solvent, thereby prolonging the contact time between the bubbles or liquid particles and the solvent, and further improving the mixing effect between the two fluids.

[0052] Of course, the propulsion mechanism is suitable for propelling the liquid as a solvent in a static liquid, and can generate a certain flow rate with very low power consumption. If the fluid mixing device is placed in a flowing liquid, such as in a river with a certain flow rate, the propulsion mechanism can be turned off or not installed at all, thereby further reducing energy consumption.

[0053] In one embodiment, the microporous tube 2 includes hollow fiber microporous membrane filaments 201. Specifically, the hollow fiber microporous membrane filaments 201 are fibers processed from polysulfone and dimethylacetamide into hollow filaments. The microporous tube 2 can also be composed of a fiber bundle consisting of multiple hollow fiber microporous membrane filaments 201. Since the hollow fiber microporous membrane filaments 201 are currently mass-produced industrial products, compared with the aeration method using specially made non-industrial finished ceramic microporous plates (refer to patent: ZL202220852105.X), it can effectively reduce material costs and also achieve a lightweight design of the device. Of course, the microporous tube 2 is not limited to hollow fiber microporous membrane filaments 201, and can also include plastic microporous tubes, ceramic microporous tubes, metal microporous tubes, etc. This exemplary embodiment does not limit 2. It is understood that the smaller the diameter of the microporous tube 2, the lower the resistance and the lower the energy consumption.

[0054] In one embodiment, referring to Figures 2 and 4, the movable support includes a transverse frame 7 arranged laterally, with an inlet structure 6 disposed on the edge of the transverse frame 7. Multiple microporous tubes 2 are arranged in parallel along the transverse direction within the transverse frame 7. When gas or liquid is introduced into the inlet structure 6, the gas or liquid can only enter the multiple microporous tubes 2 through the inlet structure 6, and thus exit through the multiple micropores of the multiple microporous tubes 2. By arranging the multiple microporous tubes 2 in parallel along the transverse direction within the transverse frame 7, the multiple microporous tubes 2 can be effectively protected and stabilized.

[0055] Furthermore, multiple horizontal frames 7 can be provided, with at least some of the horizontal frames 7 arranged sequentially in the vertical direction (i.e., multiple horizontal frames 7 stacked vertically, this arrangement is not shown in the attached figure), thereby improving space utilization and increasing the number of microporous tubes 2 to increase the yield of bubbles or liquid particles. In addition, considering that bubbles or liquid particles will pass through the gap between two adjacent microporous tubes 2 in the horizontal direction when they rise, in any two adjacent horizontal frames 7 arranged sequentially in the vertical direction, multiple microporous tubes 2 in one horizontal frame 7 are aligned vertically with multiple microporous tubes 2 in the other horizontal frame 7, so that the rising bubbles or liquid particles are not blocked by the microporous tubes 2 above, thereby improving the mixing effect between the bubbles or liquid particles and the liquid as a solvent.

[0056] In one embodiment, referring to Figures 2 and 4, the inlet structure 6 includes a distribution channel 601 and an inlet pipe 602. The distribution channel 601 can be a U-shaped channel formed in the edge of the transverse frame 7, with the ends of the multiple microporous tubes 2 connected to the distribution channel 601. One end of the inlet pipe 602 is connected to a gas supply device or a liquid supply device, and the other end is connected to the distribution channel 601, allowing high-pressure gas or liquid to enter the distribution channel 601 through the inlet pipe 602, and then be distributed by the distribution channel 601 to the multiple microporous tubes 2.

[0057] In this embodiment, multiple distribution channels 601 may be provided and distributed on both sides of the transverse frame 7. Correspondingly, multiple inlet pipes 602 may be provided and connected to multiple distribution channels 601 respectively.

[0058] In the embodiments shown in Figures 1 and 3, multiple microporous tubes 2 are arranged in parallel along the transverse direction within the transverse frame 7. To achieve this, by positioning the spray nozzle 501 of the propulsion mechanism above the multiple microporous tubes 2, the liquid flow generated by the propulsion mechanism can accurately flow above the multiple microporous tubes 2, pushing bubbles or liquid particles attached to the surface of the microporous tubes 2 away. This effectively prevents bubbles or liquid particles rising from below from pushing bubbles or liquid particles above to the liquid surface, and keeps the bubbles or liquid particles suspended in the liquid as much as possible. Furthermore, the spray nozzle 501 is positioned with a transverse opening, thereby allowing the liquid flow to be sprayed along the length of the microporous tube 2, covering the entire length of the microporous tube 2, further enhancing the mixing effect of bubbles or liquid particles.

[0059] Specifically, referring to Figures 1 and 3, the jet structure 5 can be installed on the main support 1. The jet structure 5 includes a jet pipe 502 arranged in the transverse direction, such as a PVC pipe. Both ends of the jet pipe 502 are closed, and the pipe wall is provided with the above-mentioned liquid spraying port 501 and a liquid inlet communicating with the liquid discharge end of the liquid pump 4. The liquid spraying port 501 extends from one end of the jet pipe 502 to the other end.

[0060] In one embodiment, referring to Figures 1 and 3, the transverse frame 7 includes a first transverse frame 701 and a second transverse frame 702 arranged at transverse intervals. The vibration device 301 is connected between the first transverse frame 701 and the second transverse frame 702. The vibration mechanism 3 also includes a plurality of elastic devices 302 arranged transversely around the movable support. Both ends of each elastic device 302 are respectively connected to the main support 1 and the movable support.

[0061] Specifically, in the embodiments shown in Figures 1 and 2, each elastic device 302 is arranged extending laterally. The vibration device 301 connects the first transverse frame 701 and the second transverse frame 702 via a mounting ring, so that the horizontal centers of gravity of the first transverse frame 701, the second transverse frame 702, and the vibration device 301 are all on the same plane. The vibration device 301 is configured as a vibration motor, and the output shaft of the vibration motor extends vertically. An eccentric block is connected to the end of the output shaft. The output shaft drives the eccentric block to rotate at high speed. With the coordinated operation of the elastic devices 302 arranged laterally, the first transverse frame 701 and the second transverse frame 702 can synchronously generate transverse vibration, thereby shaking off bubbles or liquid particles attached to the surface of the microporous tube 2.

[0062] In the embodiments shown in Figures 3 and 4, each elastic device 302 extends vertically, and the vibration device 301 is connected to the first transverse frame 701 and the second transverse frame 702 via four mounting feet. The vibration device 301 is configured as a vibration motor, with its output shaft extending horizontally. An eccentric block is connected to the end of the output shaft, which drives the eccentric block to rotate at high speed. With the coordinated operation of the vertically extending elastic devices 302, the first transverse frame 701 and the second transverse frame 702 can synchronously generate vertical vibrations, which can also shake off bubbles or liquid particles adhering to the surface of the microporous tube 2.

[0063] In one embodiment, referring to Figures 1 and 3, the fluid mixing device further includes a cleaning mechanism. Specifically, the cleaning mechanism includes a brush 8 and a cleaning power unit 9. The cleaning power unit 9 is used to drive the brush 8 to move and scrub the walls of the multiple microporous tubes 2, thereby removing microbial adhesives adhering to the walls of the multiple microporous tubes 2 and preventing blockage of the micropores.

[0064] Furthermore, with the first transverse frame 701 and the second transverse frame 702 provided, the brush 8 includes a first brush and a second brush. The cleaning power unit 9 is fixed to the main support 1 by a mounting bracket and includes a vertically arranged cleaning power shaft 901. The cleaning mechanism also includes a U-shaped connecting rod 10, and both the first brush and the second brush are connected to the cleaning power shaft 901 via the U-shaped connecting rod 10. Thus, driven by the cleaning power unit 9, the U-shaped connecting rod 10 can rotate synchronously with the cleaning power shaft 901, thereby driving the first brush and the second brush to rotate around the cleaning power shaft 901. This allows the first brush and the second brush to sequentially clean the walls of the multiple microporous tubes 2 in the first transverse frame 701 and the second transverse frame 702, thereby improving cleaning efficiency.

[0065] Referring to Figures 1 and 3, two cleaning mechanisms can be provided, distributed above and below the movable support, thereby cleaning the upper and lower walls of the multiple microporous tubes 2 and further improving the cleaning effect. In practical applications, the cleaning power unit 9 can be set to drive the brush 8 to move for half a minute every 10 minutes. The specific interval and running time can also be determined according to the actual situation, and this embodiment does not limit this.

[0066] It should be further explained that for mixing immiscible liquids, the less dense liquid can be pressurized by a pump and fed into the distribution tank 601 through the inlet pipe 602. From there, it is distributed to multiple microporous tubes 2, causing the lighter liquid to precipitate through the micropores of the tubes, forming micro- and nano-sized liquid particles. Simultaneously, a vibration mechanism 3 drives the microporous tubes 2 to generate small-amplitude, high-frequency vibrations, allowing these micro- and nano-sized liquid particles to enter the other immiscible, denser liquid. After the less dense liquid has been transported, the pre-mixed liquid can be pressurized by a pump and reintroduced into the microporous tubes 2 for repeated mixing until the desired mixing effect is achieved. This method is applicable to mixing two or more liquids with different physical properties.

[0067] The low power consumption effect of the fluid mixing device in the above embodiment will be further explained below through specific parameters.

[0068] The horizontal frame 7 encloses a 60cm*25cm planar space. 10-nanometer hollow fiber microporous membrane filaments 201 are used as microporous tubes 2. The aeration length of the hollow fiber microporous membrane filaments 201 is 50cm, with a total of 100 filaments, a total length of 50 meters, and a tube diameter of 1mm.

[0069] Taking the introduced gas as an example, when the inlet gas pressure is 250 kPa, the inlet volume is 3 liters per minute, which is equivalent to an inlet volume of 3*(1+2.5)=10.5 liters under standard atmospheric pressure;

[0070] A screw air compressor is used to generate high-pressure gas. According to the parameters provided by the manufacturer, the energy consumption for gas pressurization is 0.73 watts per liter per minute.

[0071] When generating micro-nano-scale bubbles, the vibration motor of the vibration device 301 consumes 15 watts, which means that the average energy consumption for cutting 1 liter per minute is 15 / 10.5 = 1.42 watts.

[0072] The liquid pump consumes 30 watts, and the propulsion energy consumption is 2.85 watts per liter / minute (30 / 10.5 = 2.85 watts).

[0073] In summary, the total energy consumption of the fluid mixing device of this application in cutting 1 liter / minute airflow into micro-nano bubbles and pushing them into the water body is 1.42 + 0.73 + 2.85 = 5 watts; if the liquid pump 4 is not required in the flowing liquid, the total energy consumption is 1.42 + 0.73 = 2.15 watts.

[0074] If the dissolved air pump used in the existing technology is used to produce microparticles, taking the parameters disclosed by Shanghai Yidun Dissolved Air Pump as an example, the air intake of a dissolved air pump with a power of 11 kilowatts is 12.5 liters per minute, then the energy consumption per liter per minute is 880 watts.

[0075] Therefore, compared with the dissolved air pump, the fluid mixing device of this application can reduce energy consumption by at least 875 watts. If the liquid pump 4 is not required in the flowing liquid, the energy consumption can be reduced by even 877.5 watts, which greatly reduces energy consumption and saves a lot of operating costs, which is conducive to its application and promotion in actual production.

[0076] On the other hand, as shown in Figure 5, this application also provides another fluid mixing device, which further includes a gas release component, an annular elastic element 12, and a vibration device 301. The gas release component is movably connected to the main support 1 and includes a gas release plate 11 for releasing bubbles in the liquid. The annular elastic element 12 is disposed on the main support 1 and surrounds the radially outer side of the gas release plate 11. The vibration device 301 is connected to the gas release component to drive the gas release plate 11 to vibrate radially (as shown in the left-right direction of Figure 5).

[0077] In this embodiment, the gas release plate 11 is an integrated plate, which can be a circular plate, a rectangular plate, or an irregularly shaped plate, etc. The annular elastic member 12 is arranged around the gas release plate 11, which can not only form radial restraint around the gas release plate 11, but also play the role of energy storage buffer and energy release drive. The gas release plate 11 can be a hydrolysis plate that can generate bubbles by hydrolysis reaction with liquid, or it can be a microporous plate that allows gas to pass through the plate to generate bubbles. The vibration device 301 can be a vibration motor with an eccentric block connected to the output shaft.

[0078] Based on the above design, when the gas release component is immersed in the liquid, the vibration device 301 drives the gas release plate 11 to vibrate in small-amplitude, high-frequency circles around each static gas outlet point. The annular elastic element 12 stores and releases the vibration energy, forming a high-intensity tangential shear flow between the surface of the gas release plate 11 and the liquid. This directly cuts the bubbles released by the gas release plate 11. The radial motion generates fluid shear parallel to the surface of the gas release plate 11, which is more effective at removing bubbles than vertical vibration. This completely eliminates the reliance on high-power fluid shearing machines in existing technologies. Simultaneously, a small vibration motor can replace the high-energy-consuming water pump and fan system, significantly reducing the energy consumption for gas dissolution. Combined with the energy storage and release function of the annular elastic element 12, the energy efficiency of the vibration device 301 can be further improved. The energy consumption of the vibration device 301 is only used to drive the vibration and overcome the frictional resistance of the liquid, further reducing energy consumption. Furthermore, the design of the annular elastic element 12 saves more radial space than a conventional spring suspension design, making the device structure more compact and simple.

[0079] In one embodiment, the annular elastic element 12 is an annular spring, such as a plug spring with an O-shaped or V-shaped cross-section. When the vibration device 301 drives the release plate 11 to vibrate radially at high frequency, the annular spring can provide radial rigid support for the release plate 11, and focus the vibration energy onto the surface of the release plate 11 during compression and release, exciting a high-intensity tangential shear flow that instantly cuts the newly formed bubbles to the submicron level. In this embodiment, the annular spring can be a metal spring. In other embodiments, the annular elastic element 12 can also be an elastic element made of elastic material, such as an annular elastic colloid. It can be hollow or solid. Hollow annular elastic colloids have better elasticity and are more suitable for vibration conditions with high elasticity feedback.

[0080] In one embodiment, the gas release assembly further includes a base plate 13, with the gas release plate 11 fixed to the base plate 13. A vibration device 301 is connected to the base plate 13 to drive the gas release plate 11 to vibrate. Modular fixing typically refers to the ability to easily connect and disassemble the gas release plate 11 and the base plate 13 while ensuring a stable connection. There are various ways to achieve this modular fixing, and the specific choice depends on factors such as the application scenario, stress requirements, space constraints, and cost. For example, pre-drilled threaded holes or through holes (for nuts) on the two plates can be used for connection with bolts or screws. Alternatively, commonly used modular fixing components such as quick-clamping mechanisms, snap-fit ​​devices, magnetic assemblies, pins, and bushings can be employed. This application does not limit the specific methods used.

[0081] On the one hand, by rigidly connecting the venting plate 11 to the base plate 13, the complete transmission of the vibration waveform can be ensured; on the other hand, the vibration energy of the vibration device 301 is transmitted to the venting plate 11 through the base plate 13, which can avoid uneven local amplitude of the venting plate 11 and improve the cutting efficiency of bubbles. It should be further noted that, when the base plate 13 is provided, the annular elastic element 12 can be arranged around the base plate 13, and the base plate 13 bears the impact of vibration, effectively avoiding wear on the venting plate 11.

[0082] Furthermore, when the gas release plate 11 is formed as a microporous plate, as shown in Figure 5, the gas release plate 11 and the bottom plate 13 are joined vertically to define the gas release chamber 14. The bottom plate 13 has an air inlet 1301 that communicates with the gas release chamber 14. Thus, gas can be input into the gas release chamber 14 through the air inlet 1301. After a certain gas pressure is formed in the gas release chamber 14, the gas is output through the microporous plate, forming bubbles on the surface of the microporous plate. Then, after being vibrated by the vibration device 301, the bubbles leave the surface of the microporous plate and dissolve in the liquid.

[0083] It should be noted that the microporous plate has densely arranged pores, which can generate a large number of micro- and nano-sized bubbles. In this embodiment, a ceramic microporous plate can be used as the gas release plate 11. The capillary effect of the microporous plate will cause the bubbles formed in the micropores to be unable to escape. Therefore, the high-pressure environment formed by the gas release chamber 14 and the high-frequency vibration of the vibration device 301 are needed to facilitate the release of micro- and nano-sized bubbles in the liquid.

[0084] As shown in Figure 5, the top wall of the base plate 13 has a protrusion, and the venting plate 11 abuts against the protrusion, thereby enclosing the venting cavity 14. In one embodiment, the base plate 13 and the protrusion can be integrally formed, that is, the protrusion is part of the base plate 13. In other embodiments, the protrusion and the base plate 13 are separate, wherein the protrusion can be formed as a sealing ring plate 15, which is disposed between the venting plate 11 and the base plate 13, and together with the venting plate 11 and the base plate 13, defines the venting cavity 14. Specifically, the sealing ring plate 15 is disposed around the edge of the venting plate 11. Referring to Figure 5, when the venting plate 11 is an annular venting plate, two sealing ring plates 15 can be provided accordingly, one disposed at the outer ring edge of the venting plate 11, and the other disposed at the inner ring edge of the venting plate 11. In this case, the enclosed venting cavity 14 is an annular cavity.

[0085] In the above embodiments, the sealing ring plate 15 can be a sealing rubber ring, which can effectively prevent air leakage in the gas release chamber 14 and ensure the sealing performance of the gas release chamber 14.

[0086] When the gas release plate 11 is a hydrolysis plate used to generate a hydrolysis reaction with the liquid, there is no need to set up a gas release chamber 14, a sealing ring plate 15 and a corresponding gas supply source. Simply immerse the gas release plate 11 in the liquid of the gas release plate 11 to generate bubbles through the hydrolysis reaction.

[0087] In one embodiment, the gas release plate 11 is an electrode plate. By energizing the gas release plate 11, an electrolytic reaction is carried out between the gas release plate 11 and the liquid to produce corresponding bubbles. This method is convenient, quick, and relatively environmentally friendly, and does not pollute water bodies. In other embodiments, the appropriate hydrolysis material for the gas release plate 11 can be selected according to the type of liquid and the target product. For example, when oxygen production is required, peroxide can be used to make the gas release plate 11; when hydrogen production is required, an active metal or metal hydride can be used to make the gas release plate 11. This application does not limit this.

[0088] In one embodiment, as shown in FIG5, the fluid mixing device includes a lifting device 16, through which the gas release component is suspended from the main support 1. Specifically, the main support 1 is provided with a crossbeam, and the lifting device 16 includes a first lifting ring, a lifting rope, and a second lifting ring connected in sequence. The first lifting ring is fixed to the crossbeam, and the second lifting ring is fixedly connected to the gas release component, for example, by means of a bolt assembly to connect the gas release plate 11. The gas release component is suspended from the main support 1 by the lifting device 16 to form an elastic vibration system. When the vibration device 301 drives the gas release plate 11 to vibrate radially at high frequency, the lifting device 16 can release multi-dimensional degree-of-freedom stress, so that the vibration energy is focused on the gas release plate 11 without loss, which is beneficial to improving vibration efficiency and bubble shearing effect.

[0089] In one embodiment, the venting plate 11 is arranged laterally, and the main support 1 includes a support vertical plate 101 disposed on the lateral outer side of the venting plate 11. The support vertical plate 101 is provided with a support limiting groove 102 opening toward the venting plate 11. The annular elastic member 12 includes an outer ring portion embedded in the support limiting groove 102 and an inner ring portion extending beyond the support limiting groove 102 and used to abut against the outer edge portion of the annular elastic member 12. Thus, the annular elastic member 12 can be partially nested in the support limiting groove 102, and a gap can be left between the annular elastic member 12 and the venting plate 11 to allow the venting plate 11 to vibrate and displace. Moreover, when the venting plate 11 vibrates, it can be displaced to abut against the inner ring portion of the venting plate 11, forming elastic compression and release, which helps to reduce the loss of vibration energy.

[0090] This application does not limit the specific structure and number of the support vertical plate 101. For example, in the embodiment shown in Figure 5, the support vertical plate 101 can be rolled from a flat vertical plate into a cylindrical vertical plate. In this case, the venting plate 11 is located in the inner cavity of the cylindrical vertical plate. In other embodiments, multiple support vertical plates 101 can be provided. Multiple support vertical plates 101 are arranged around the venting plate 11 in sequence. Each support vertical plate 101 is provided with a support limiting groove 102. The heads and tails of each support limiting groove 102 are aligned so that the annular elastic member 12 can be embedded.

[0091] In one embodiment, as shown in FIG5, the gas release plate 11 is an annular gas release plate. When a base plate 13 is provided, the base plate 13 is also an annular base plate. The vibration device 301 is disposed in the central hole of the annular gas release plate 11 and the base plate 13. Thus, the vibration device 301 drives the annular gas release plate directly in the center, forming a concentric circle energy radiation state. The vibration wave diffuses evenly from the center of the annular gas release plate to the outer edge of the annular plate, which helps to eliminate the energy attenuation caused by eccentric vibration.

[0092] In summary, the fluid mixing device of this application can be used as a micro / nano bubble generator, which is the core of micro / nano bubble technology. Therefore, this application can significantly reduce the energy consumption of micro / nano bubble generators; as in the above case, energy consumption can be reduced by more than 400 times. It is worth noting that micro / nano bubble technology was first applied in Japan in 2000. Over the past 20 years, researchers worldwide have discovered its unimaginable effects in numerous fields, including national defense, river and lake water management, sewage and wastewater treatment, green and high-yield agriculture, soil remediation, industrial flotation, ozone oxidation performance enhancement, ship speed improvement, medical and health care, energy and chemical industry, and carbon peaking and carbon neutrality. However, because the energy consumption of micro / nano bubble generators is extremely high, the cost outweighs the benefits, resulting in a small scale of application and the lack of industrialization. This application has bridged the last mile in the application of micro-nano bubble technology, enabling its large-scale application. For example, it can be used in aquaculture to achieve ultra-high-density fish farming. Moreover, compared with the microporous flat plate material used in the previous patent (ZL202220852105.X), the cost of this application is significantly reduced, which is more conducive to industrialization. Its economic value will be immeasurable.
