Description

Technical Field

[0001] The present application relates to fluid mixing technology, and in particular to a fluid mixing device. Background Art

[0002] As the name implies, a fluid mixing device is used to mix two or more different fluids, especially two or more immiscible fluids, such as immiscible gases and liquids, two immiscible liquids, etc. The working principle of a fluid mixing device is usually based on physical or chemical methods. Through specific design structures and operating parameters, the two immiscible fluids can achieve the desired mixing effect during the mixing process. For example, by using a fluid mixing device with a micronizing function to micronize the fluid as the solute, the mixing effect between the two fluids can be improved from several aspects, such as increasing the contact area of ​​the two-phase interface, reducing the solute diffusion distance, and increasing the reaction rate.

[0003] In traditional technology, spray, ultrasound, stirring and other technologies are often used to achieve fluid micronization, thereby accelerating the mixing process. At this stage, more new micronization technologies and equipment are used, such as Venturi jet tubes, dissolved air pumps, etc. However, as far as current technology is concerned, it is still difficult to achieve fluid micronization under low speed and low pressure conditions. It is necessary to equip a high-power high-lift water pump to create a high-speed water flow to squeeze and cut the liquid or gas. Although the liquid particles or bubbles produced by this method are small and the mass transfer efficiency is high, the power consumption is extremely large and the cost is high, which to a certain extent restricts the application and promotion of fluid micronization in fluid mixing operations. Summary of the invention

[0004] In response to at least one of the above-mentioned defects or shortcomings of the prior art, the present application provides a fluid mixing device that can achieve fluid micronization, improve the mixing effect between fluids, and has extremely low operating energy consumption, which can effectively save production costs.

[0005] In order to achieve the above object, the present application provides a fluid mixing device, comprising:

[0006] Main support;

[0007] A movable bracket, movably connected to the main bracket and provided with an inlet structure;

[0008] A plurality of microporous tubes arranged on the movable support and connected to the flow inlet structure; and

[0009] The vibration mechanism comprises a vibration device connected to the movable bracket to drive the plurality of microporous tubes to vibrate.

[0010] In some embodiments, the microporous tube comprises a hollow fiber microporous membrane.

[0011] In some embodiments, the movable support includes a transverse frame arranged in the transverse direction, the inlet structure is arranged on the frame edge of the transverse frame, and the plurality of microporous tubes are arranged in parallel in the transverse direction in sequence within the transverse frame.

[0012] In some embodiments, the transverse frames are provided in plurality, and at least some of the transverse frames are arranged vertically in sequence. In any two adjacent transverse frames arranged vertically in sequence, the plurality of microporous tubes in one of the transverse frames are vertically aligned one by one with the plurality of microporous tubes in another transverse frame.

[0013] In some embodiments, the flow inlet structure includes a flow distribution groove formed in the frame edge portion and a flow inlet pipe connected to the flow distribution groove, and ends of the plurality of microporous tubes are all connected to the flow distribution groove.

[0014] In some embodiments, the transverse frame includes a first transverse frame and a second transverse frame arranged at intervals along the transverse direction, the vibration device is connected between the first transverse frame and the second transverse frame, and the vibration mechanism also includes a plurality of elastic devices arranged laterally around the movable bracket, and both ends of each of the elastic devices are respectively connected to the main bracket and the movable bracket.

[0015] In some embodiments, the fluid mixing device further comprises:

[0016] The cleaning mechanism comprises a brush and a cleaning power device, wherein the cleaning power device is used for driving the brush to move so as to clean the tube walls of the plurality of microporous tubes.

[0017] In some embodiments, the transverse frame includes a first transverse frame and a second transverse frame arranged at intervals along the transverse direction, the cleaning power device is disposed on the main bracket and includes a cleaning power shaft arranged along the vertical direction, the brush includes a first brush and a second brush, and the cleaning mechanism also includes a U-shaped connecting rod, and the first brush and the second brush are both connected to the cleaning power shaft through the U-shaped connecting rod.

[0018] In some embodiments, the fluid mixing device includes a flow-pushing mechanism, which includes a liquid pump and a jet structure connected to the discharge end of the liquid pump, and the jet structure is provided with a liquid spray port. The flow-pushing mechanism can drive the liquid to spray out from the liquid spray port toward the top of the plurality of microporous tubes through the liquid pump.

[0019] In some embodiments, the jet structure includes a jet tube located above the plurality of microporous tubes and extending laterally, the two ends of the jet tube are closed, the jet port and the liquid inlet connected to the discharge end of the liquid pump are opened on the tube wall of the jet tube, and the jet port extends from one end of the jet tube to the other end.

[0020] Through the above technical scheme, the fluid mixing device of the present application can be set as a whole in a liquid as a solvent. During the mixing operation, it is only necessary to pass the high-pressure gas or another liquid as a solute into multiple microporous tubes, and drive the movable bracket to move through the vibration mechanism to drive the microporous tubes to vibrate at high frequency, so as to generate micro-nano bubbles or liquid particles as solutes, and make the micro-nano bubbles or liquid particles separate from the corresponding microporous tubes to mix into the liquid as a solvent to form a uniform phase, thereby achieving an ideal mixing effect. In the process, the work done by the vibration mechanism is only used to drive the movable bracket and multiple microporous tubes to vibrate and overcome the friction resistance of the liquid.

[0038] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0039] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0040] like Figures 1 to 4 As shown, an exemplary embodiment of the present application provides a fluid mixing device that can be disposed as a whole below the liquid surface of a liquid serving as a solvent, and can micronize a gas or another liquid serving as a solute to form micro-nano bubbles or liquid particles to mix with the liquid serving as a solvent.

[0041] Specifically, the fluid mixing device includes a main support 1, a movable support, a plurality of microporous tubes 2, a vibration mechanism 3 and a flow-pushing mechanism. Among them, the movable support can be movably connected to the main support 1, and is provided with an inflow structure 6 for the flow of a fluid as a solute, and a plurality of microporous tubes 2 are arranged on the movable support and are connected with the inflow structure 6, so that the fluid as a solute enters the microporous tube 2 through the inflow structure 6, and is discharged from the micropores of the microporous tube 2 to form micro-nano bubbles or liquid particles. The vibration mechanism 3 includes a vibration device 301 connected to the movable support to be able to drive the plurality of microporous tubes 2 to vibrate, the flow-pushing mechanism includes a liquid pump 4 and a jet structure 5 connected to the discharge end of the liquid pump 4, the jet structure 5 is provided with a liquid spraying port 501, and the flow-pushing mechanism can drive the liquid as a solvent through the liquid pump 4, so that it is sprayed from the liquid spraying port 501 toward the top of the plurality of microporous tubes 2.

[0042] Therefore, the fluid mixing device of this exemplary embodiment can be integrally arranged in a liquid serving as a solvent. During the mixing operation, it is only necessary to introduce a high-pressure gas or another liquid serving as a solute into a plurality of microporous tubes 2 through the inlet structure 6, and drive the movable bracket to move back and forth through the vibration mechanism 3 to drive the microporous tubes 2 to vibrate at a high frequency, thereby generating micro-nano bubbles or liquid particles, and making the micro-nano bubbles or liquid particles separate from the corresponding microporous tubes 2 to be mixed into the liquid serving as a solvent, thereby achieving an ideal mixing effect.

[0043] In the above process, under the influence of the adsorption force of the microporous tube 2 material, the bubbles or liquid particles discharged from the micropores may be unable to escape from the microporous tube 2. For this reason, under the vibration intervention of the vibration mechanism 3, the microporous tube 2 and the liquid as a solvent can produce high-speed relative motion, and the bubbles or liquid particles just discharged from the microporous tube 2 are cut by the liquid, thereby overcoming the adsorption force of the microporous tube 2 on the bubbles or liquid particles, without relying on the buoyancy of the bubbles or liquid particles themselves, so that the bubbles or liquid particles can be mixed into the liquid as a solvent in a micro-nano state. Vibration cutting can produce bubbles or liquid particles with smaller particle sizes than non-vibration cutting. In practical applications, micro-nano bubbles or liquid particles can be produced by controlling the inflow flow rate and vibration frequency.

[0044] The key is that the work done by the vibration mechanism 3 is only used to drive the movable bracket and the multiple microporous tubes 2 to vibrate and overcome the friction resistance of the liquid. Compared with the existing high-lift water pump to create a high-speed water flow to squeeze and cut the liquid or gas as a solute, the operating energy consumption is greatly reduced, thereby effectively saving operating costs. On the other hand, the fluid mixing device of this exemplary embodiment can also use the flow-pushing mechanism to pressurize the liquid as a solvent, so that it is ejected toward the top of the multiple microporous tubes 2 to form a liquid flow with a certain flow rate, and the newly formed tiny bubbles or liquid particles are pushed away from the microporous tubes 2 by the liquid flow, and the bubbles or liquid particles after being pushed away are suspended in the liquid as a solvent, thereby prolonging the contact time between the bubbles or liquid particles and the solvent, thereby further improving the mixing effect between the two fluids.

[0045] Of course, the flow-pushing mechanism is suitable for pushing the liquid as a solvent to flow in a stationary liquid, and can generate a liquid flow of a certain flow rate at only very low power consumption. If the fluid mixing device is set in a flowing liquid, such as a river with a certain flow rate, the flow-pushing mechanism can be turned off, or not set, thereby further reducing energy consumption.

[0046] In one embodiment, the microporous tube 2 includes a hollow fiber microporous membrane filament 201. Specifically, the hollow fiber microporous membrane filament 201 is a fiber filament processed into a hollow inner cavity using polysulfone and dimethylacetamide as raw materials, and the microporous tube 2 can also be composed of a fiber bundle composed of a plurality of hollow fiber microporous membrane filaments 201. Since the hollow fiber microporous membrane filament 201 is a large-scale industrialized finished product currently produced in large quantities, compared with the method of aeration using a specially made non-industrialized ceramic microporous flat plate (reference patent: ZL202220852105.X), the material cost can be effectively reduced, and the lightweight setting of the device can also be achieved. Of course, the microporous tube 2 is not limited to including 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 can be understood that the smaller the diameter of the microporous tube 2, the smaller the resistance and the lower the energy consumption.

[0047] In one embodiment, referring to Figure 2 and Figure 4 The movable bracket includes a transverse frame 7 arranged in the transverse direction, an inlet structure 6 is arranged on the frame edge of the transverse frame 7, and a plurality of microporous tubes 2 are arranged in parallel in the transverse direction in sequence in the transverse frame 7. After the gas or liquid is passed into the inlet structure 6, the gas or liquid can only enter the plurality of microporous tubes 2 from the inlet structure 6, and then be discharged from the plurality of micropores of the plurality of microporous tubes 2. By arranging the plurality of microporous tubes 2 in parallel in the transverse direction in sequence in the transverse frame 7, the plurality of microporous tubes 2 can be effectively protected and stabilized.

[0048] Furthermore, the transverse frames 7 may be provided with a plurality of transverse frames, at least some of which are arranged in sequence in the vertical direction (i.e., a plurality of transverse frames 7 are stacked up and down, and the attached drawings do not show this arrangement), so that the space utilization rate can be improved, and the number of microporous tubes 2 can be increased 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 transverse direction when rising, for this reason, in any two adjacent transverse frames 7 arranged in sequence in the vertical direction, the plurality of microporous tubes 2 in one transverse frame 7 and the plurality of microporous tubes 2 in another transverse frame 7 are arranged one by one in the vertical direction, so that the rising bubbles or liquid particles will not be blocked by the upper microporous tubes 2, thereby improving the mixing effect between the bubbles or liquid particles and the liquid as a solvent.

[0049] In one embodiment, referring to Figure 2 and Figure 4 , the inlet structure 6 includes a distribution groove 601 and an inlet pipe 602. The distribution groove 601 may be a U-shaped groove formed in the frame edge of the transverse frame 7, and the ends of the plurality of microporous tubes 2 are all connected to the distribution groove 601; one end of the inlet pipe 602 is connected to the gas supply device or the liquid supply device, and the other end is connected to the distribution groove 601, so that the high-pressure gas or liquid can enter the distribution groove 601 through the inlet pipe 602, and then be diverted to the plurality of microporous tubes 2 by the distribution groove 601.

[0050] In this embodiment, a plurality of flow distribution grooves 601 may be provided, distributed on both side frame edges of the transverse frame 7 , and correspondingly, a plurality of flow inlet pipes 602 may be provided, respectively connected to the plurality of flow distribution grooves 601 .

[0051] exist Figure 1 and Figure 3 In the illustrated embodiment, a plurality of the microporous tubes 2 are arranged in parallel in the transverse direction in the transverse frame 7. To this end, by setting the liquid spraying port 501 of the flow-pushing mechanism above the plurality of microporous tubes 2, the liquid flow generated by the flow-pushing mechanism can accurately flow to the top of the plurality of microporous tubes 2, and push the bubbles or liquid particles attached to the surface of the microporous tubes 2 to detach, thereby effectively preventing the bubbles or liquid particles of the microporous tubes 2 rising from below from lifting the bubbles or liquid particles above to the liquid surface, and making the bubbles or liquid particles as much as possible suspended in the liquid as a solvent. In addition, the liquid spraying port 501 is arranged to open in the transverse direction, thereby being able to spray the liquid flow along the length direction of the microporous tube 2, so that the flow range of the liquid flow covers the full length of the microporous tube 2, and further improving the mixing effect of the bubbles or liquid particles.

[0052] Specifically, refer to Figure 1 and Figure 3 The jet structure 5 can be set on the main support 1, and the jet structure 5 includes a jet pipe 502 arranged in the transverse direction, such as a PVC pipe. The two ends of the jet pipe 502 are closed, and the above-mentioned spray port 501 and the liquid inlet connected to the discharge end of the liquid pump 4 are opened on the pipe wall. The spray port 501 extends from one end of the jet pipe 502 to the other end.

[0053] In one embodiment, referring to Figure 1 and Figure 3 The transverse frame 7 includes a first transverse frame 701 and a second transverse frame 702 arranged at intervals along the transverse direction, the vibration device 301 is connected between the first transverse frame 701 and the second transverse frame 702, and the vibration mechanism 3 also includes a plurality of elastic devices 302 arranged around the movable bracket in the transverse direction, and both ends of each elastic device 302 are respectively connected to the main bracket 1 and the movable bracket.

[0054] Specifically, in Figure 1 and Figure 2In the embodiment shown, each elastic device 302 is arranged to extend in the transverse direction, and the vibration device 301 connects the first transverse frame 701 and the second transverse frame 702 through 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 is arranged to extend in the vertical direction. The shaft end of the output shaft is connected to an eccentric block, and the eccentric block is driven to rotate at a high speed through the output shaft. Under the coordinated operation of each elastic device 302 arranged to extend in the transverse direction, the first transverse frame 701 and the second transverse frame 702 can synchronously generate transverse vibrations, thereby playing a role in shaking off bubbles or liquid particles attached to the surface of the microporous tube 2.

[0055] exist Figure 3 and Figure 4 In the illustrated embodiment, each elastic device 302 is arranged to extend vertically, and the vibration device 301 is connected to the first transverse frame 701 and the second transverse frame 702 through four mounting feet. The vibration device 301 is configured as a vibration motor, and the output shaft of the vibration motor is arranged to extend horizontally, and the shaft end of the output shaft is connected to an eccentric block, which is driven by the output shaft to rotate at a high speed, and under the coordinated operation of each elastic device 302 arranged to extend vertically, the first transverse frame 701 and the second transverse frame 702 can synchronously generate vertical vibrations, and similarly, can play a role in shaking off bubbles or liquid particles attached to the surface of the microporous tube 2.

[0056] In one embodiment, referring to Figure 1 and Figure 3 The fluid mixing device further comprises a cleaning mechanism. Specifically, the cleaning mechanism comprises a brush 8 and a cleaning power device 9, wherein the cleaning power device 9 is used to drive the brush 8 to move to clean the tube walls of the plurality of microporous tubes 2, thereby removing microbial adhesive bodies attached to the tube walls of the plurality of microporous tubes 2 to avoid clogging the micropores.

[0057] Furthermore, in the case where the first transverse frame 701 and the second transverse frame 702 are provided, the brush 8 includes a first brush and a second brush, the cleaning power device 9 is fixed to the main bracket 1 through a mounting bracket and includes a cleaning power shaft 901 arranged vertically, and the cleaning mechanism also includes a U-shaped connecting rod 10, and the first brush and the second brush are both connected to the cleaning power shaft 901 through the U-shaped connecting rod 10. Therefore, under the drive of the cleaning power device 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, so that the first brush and the second brush sequentially wash the tube walls of the multiple microporous tubes 2 in the first transverse frame 701 and the second transverse frame 702, thereby improving the cleaning efficiency.

[0058] Reference Figure 1 and Figure 3 , two cleaning mechanisms may be provided, and the two cleaning mechanisms are distributed above and below the movable bracket, so that the upper and lower tube walls of multiple microporous tubes 2 can be cleaned, further improving the cleaning effect. In practical applications, the cleaning power device 9 can be set to drive the brush 8 to move for half a minute every 10 minutes. The specific interval time and running time can also be determined according to actual conditions, and this embodiment does not limit this.

[0059] It should be noted that, for the mixing operation between immiscible liquids, the liquid with a lower density can be pressurized by a liquid pump, and enter the distribution groove 601 through the inlet pipe 602, and then diverted from the distribution groove 601 to multiple microporous tubes 2, so that the liquid with a lower density is precipitated from the micropores of the multiple microporous tubes 2 to form micro-nano liquid particles. At the same time, the multiple microporous tubes 2 are driven by the vibration mechanism 3 to produce a small high-frequency vibration, so that the micro-nano liquid particles enter another immiscible liquid with a higher density. After the liquid with a lower density is transported, the mixed liquid after preliminary mixing can be pressurized by a liquid pump and then input into multiple microporous tubes 2, so that it is repeatedly mixed until the preset mixing effect is achieved. This method can be applied to the mixing operation between two or more liquids with different physical properties.

[0060] The low power consumption effect of the fluid mixing device of the present application is further described below through specific parameters.

[0061] The transverse frame 7 encloses a plane space of 60cm*25cm, and a 10-nanometer hollow fiber microporous membrane filament 201 is used as the microporous tube 2. The aeration length of the hollow fiber microporous membrane filament 201 is 50cm, with a total of 100 filaments, a total length of 50 meters, and a tube diameter of 1mm.

[0062] Taking the gas as an example, when the intake pressure is 250Kpa, the intake volume is 3 liters per minute, which is equivalent to the intake volume under standard atmospheric pressure 3*(1+2.5)=10.5 liters;

[0063] A screw air compressor is used to generate high-pressure gas. According to the parameters provided by the manufacturer, the energy consumption for gas pressure boost is 0.73 watts per liter per minute.

[0064] When generating micro-nano bubbles, the energy consumption of the vibration motor of the vibration device 301 is 15 watts, that is, the average energy consumption of 1 liter / minute cutting is 15 / 10.5=1.42 watts;

[0065] The energy consumption of the liquid pump 4 is 30 watts, and the energy consumption of the push flow is 1 liter / minute 30 / 10.5=2.85 watts;

[0066] In summary, the total energy consumption of the fluid mixing device of the present application for cutting 1 liter / minute of airflow into micro-nano bubbles and pushing the bubbles into the water body is 1.42+0.73+2.85=5 watts; if no liquid pump 4 is required in the flowing liquid, the total energy consumption is 1.42+0.73=2.15 watts.

[0067] If the dissolved air pump in the prior art is used to produce microparticles, taking the parameters disclosed by Shanghai Yidun dissolved air pump as an example, the dissolved air pump with a power of 11 kilowatts has an air intake of 12.5 liters per minute, and the energy consumption of 1 liter / minute is 880 watts.

[0068] Therefore, compared with the dissolved air pump, the fluid mixing device of the present application can reduce the energy consumption by at least 875 watts. If there is no need to set a liquid pump 4 in the flowing liquid, the energy consumption can even be reduced by 877.5 watts, which greatly reduces the energy consumption and greatly saves the cost of use, which is conducive to application and promotion in actual production.

[0069] In general, the fluid mixing device of the present application can be used as a micro-nano bubble generator, and the micro-nano bubble generator is the core key of the micro-nano bubble technology. Therefore, the present application can greatly reduce the energy consumption of the micro-nano bubble generator. For example, in the above case, the energy consumption is reduced by more than 400 times. It is worth noting that the micro-nano bubble technology has been applied in Japan since 2000. Over the past 20 years, researchers around the world have found that it has unimaginable effects in many fields such as national defense and military industry, river and lake water management, sewage and wastewater treatment, green and high-yield agriculture, soil management, industrial flotation, ozone oxidation performance improvement, ship speed-up, medical health, energy and chemical industry, carbon peak and carbon neutrality, etc. However, because the energy consumption of the generator that produces micro-nano bubbles is extremely high and the cost is greater than the benefit, the application scale is very small and no industry has been formed. This application has opened up the last mile of the application of micro-nano bubble technology, and can bring about large-scale application of micro-nano bubble technology. For example, it can be applied in the aquaculture industry to achieve ultra-high-density fish farming. Moreover, compared with the microporous flat plate materials used in the previous patent (ZL202220852105.X), this application has greatly reduced the cost, which is more conducive to industrialization, and its economic value will be immeasurable.
