Description

Technical Field

[0001] The invention relates to the field of bubble making equipment, and in particular to a micro-nano bubble making equipment and process. Background Art

[0002] The tiny bubbles in the liquid are called micron bubbles when the bubble diameter is below 100μm, and the bubbles with a diameter of less than 100nm are called nano bubbles. Micro-nano bubbles refer to bubbles with a diameter between tens of microns and hundreds of nanometers when bubbles occur. This type of bubble is between micron bubbles and nano bubbles, and has physical and chemical properties that regular bubbles do not have. There is a special gas state at the interface between gas and liquid. Microbubbles are tiny bubbles with a diameter of less than fifty microns (um) when bubbles occur, also called micro-nano bubbles. After microbubbles occur, the bubbles shrink by themselves. In this process, the bubbles become smaller, so the rising speed becomes slower, resulting in high melting efficiency.

[0003] In the prior art, micro-bubbles are generally formed by ultrasonic or spray methods. However, the bubbles in this forming method are relatively large in volume. When new bubbles are generated, old bubbles will be squeezed and broken, so the storage time is relatively short. Summary of the invention

[0009] A preferred technical solution, wherein the physical stripping tube is provided with an injection portion, a separation block 1 and a separation block 2 in sequence, and the physical stripping tube is divided into a pressure chamber 1 and a pressure chamber 2 by the separation block 1, and the pressure chamber 1 is connected with the pressure chamber 2 through a guide hole 1 provided on the surface of the separation block 1 near the edge, the guide hole 1 is a Y-shaped structure, and the end of the guide hole 1 is provided toward the middle of the separation block 2, the separation block 1 and the separation block 2 are both arc-shaped surfaces on one side facing the injection portion, and the separation block 2 is provided with a guide hole 2 in a Y-shaped structure, and the pressure chamber 2 is connected to the outside through the guide hole 2.

[0010] A preferred technical solution, the injection part includes a conical shell and a ball, the other side of the conical shell away from the opening is provided with a spherical hole connected to the opening, and the ball is rotatably installed in the spherical hole;

[0011] A flow channel running through both ends is arranged in the ball, and the flow channel is connected with the opening, so as to guide the bubbles to flow through the opening and eject the bubbles outward through the flow channel.

[0012] A preferred technical solution, a convex block is provided inside the spherical hole, and a slide groove corresponding to the convex block is provided on the surface of the ball bearing, the convex block is embedded in the slide groove, the convex block and the two sides of the slide groove form a strip-shaped cavity, and a connecting hole 1 connected to the strip-shaped cavity is provided on the surface of the conical shell, and the connecting hole 1 is connected to the output end of the air compressor 2 provided outside the physical stripping tube, so that the positive and negative pressures in the strip-shaped cavity can be adjusted by the air compressor 2, so that the ball bearing rotates with the positive and negative pressures, thereby changing the direction of the bubbles ejected from the flow channel;

[0013] The flow channel includes a conical mouth, a second connecting hole, a strip groove and an injection hole. The conical mouth and the injection hole are respectively connected to the left and right sides of the second connecting hole. The strip groove extends to the surface of the ball through the injection hole. The conical mouth is arranged on the side of the second connecting hole close to the opening. The conical mouth is an expanded structure, with a large-diameter end arranged toward the opening, and the inner diameter of the conical mouth is larger than the inner diameter of the opening.

[0014] The strip-shaped groove extends toward both sides, and the injection holes are arranged equidistantly along the length direction of the strip-shaped groove.

[0015] A micro-nano bubble production process, applied to the micro-nano bubble production device, comprises the following steps:

[0016] S1: Pressurize water into the mixing tube and stir it with the stirring motor in the tube body. During the stirring process, the bubbles are dispersed and discharged into the secondary pressurized atomization tube when the pressure drops.

[0017] S2: Pressurize the secondary pressurization atomization pipe, release the pressure of atomized water through the pressurization pipe 1 and the pressurization pipe 2, and perform secondary pressurization in the pressurization pipe 1 through the air pump connected to the connecting pipe 1, and discharge the pressurized water into the pipe body;

[0020] Compared with the prior art, this technical solution has the following advantages:

[0021] Since the liquid sensor is arranged above the negative pressure extraction plate, it can monitor the liquid level of the electrolyte in the electrolysis tube in real time. This ensures that the electrolyte is not excessive or insufficient, thereby maintaining the stability and efficiency of the electrolysis process. During the electrolysis process, bubbles may rise and try to escape from the electrolyte. The liquid sensor can indirectly monitor the movement of bubbles by monitoring the liquid level and adjust the working state of the negative pressure extraction plate when necessary to ensure that the bubbles are effectively extracted and transmitted to the next stage. The electrolyte is usually corrosive or toxic, so accurate control of the liquid level is crucial to the safety of the operator. The liquid sensor provides real-time liquid level information, which helps the operator take timely measures to prevent electrolyte overflow or leakage.

[0022] When air compressor one is working, it will inject bubbles into the flow channel in the ball through the opening. Under the guidance of the conical mouth, the bubbles will flow smoothly into the connecting hole two and flow along the strip groove to the injection hole. At this time, the ball is in a stationary state, and the injection direction of the bubble is determined by the position of the injection hole. However, when we want to change the injection direction of the bubble, we need to use the power of air compressor two. Air compressor two injects gas into the strip cavity through connecting hole one, thereby changing the pressure in the cavity. Due to the interlocking design of the bump and the slide groove, when the pressure in the strip cavity changes, the ball will be acted upon by the force and begin to rotate. The rotation of the ball changes the position of the injection hole relative to the physical stripping tube, thereby realizing the control of the bubble injection direction. By adjusting the output pressure of air compressor 2, we can accurately control the rotation angle and speed of the ball, and thus achieve precise control of the bubble injection direction. By adjusting the injection direction, we can make the bubbles more evenly distributed in the physical stripping tube, which helps to reduce the aggregation and collision of bubbles, thereby improving the stability and uniformity of the bubbles. When bubbles are ejected in different directions, the collision and friction between them will be more frequent and intense, which helps to further strip the bubbles and make them smaller and more uniform. At the same time, the physical impact during the stripping process also helps to increase the activity of the bubbles. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION Embodiment 1

[0038] This embodiment is as Figures 1 to 9 As shown, the present invention proposes a micro-nano bubble production device, including a secondary pressurized atomization tube 1, a mixing tube 2, an electrolysis tube 3, and a physical stripping tube 4 that are sequentially connected, wherein the mixing tube 2 includes a tube body 21 and a stirring motor 22, and the stirring motor 22 is arrayed in the tube body 21;

[0039] The secondary pressurized atomizing tube 1 comprises a pressurized tube 11, a pressurized tube 2 12 and a fixing block 13, the pressurized tube 11 and the pressurized tube 2 12 are fixed by the fixing block 13, the pressurized tube 11 and the pressurized tube 2 12 are respectively provided with chambers 1 and 2, the chamber 1 in the pressurized tube 11 is connected to the air pump through a connecting tube 111, and the chamber 2 in the pressurized tube 2 12 is provided with a separator 121, the chambers 1 and 2 are connected through a connecting port 112, the connecting port 112 is a flared structure, and the small-diameter end of the connecting port 112 is arranged toward the chamber 1;

[0040] The chamber 1 is an expanded structure, and the connecting pipe 111 is connected to an end with a large diameter in the chamber 1.

[0041] The secondary pressurized atomizing tube 1 of the present invention uses a special structural design to pressurize the chamber 1 in the pressurized tube 1 11 by using an air pump, so that the gas quickly enters the chamber 2 of the pressurized tube 2 12 through the flared structure, where the gas is divided and refined by the partition sheet 121 to form preliminary tiny bubbles;

[0042] Compared with the ultrasonic method or spray method mentioned in the background technology, the present invention significantly improves the stability and storage time of bubbles through multi-step treatment such as secondary pressurization, electrolysis and physical stripping, which avoids the problem of old bubbles being squeezed and broken when new bubbles are generated, allowing the bubbles to maintain their micro-nanoscale size and characteristics for a longer time.

[0043] Subsequently, the mixed bubbles enter the electrolysis tube 3, where the bubbles are further refined and their stability is enhanced by electrolysis. Finally, the physical stripping tube 4 further strips and disperses the bubbles by physical methods to ensure that the bubbles finally output have the required micro-nano size and stability. The device of the present invention not only refines the bubble size, but also enhances the functionality of the bubbles. For example, electrolysis can further refine the bubbles and improve their stability.

[0044] Furthermore, the electrolysis tube 3 is provided with a partition 31, and a conductive sheet 32, a liquid sensor 34, and a negative pressure extraction plate 35 arranged in the partition 31. The conductive sheet 32 ​​is arranged at the bottom of the partition 31, the negative pressure extraction plate 35 is fixed in the middle of the partition 31, and the liquid sensor 34 is arranged above the negative pressure extraction plate 35. The partition 31 is filled with an electrolyte 36, and the electrolyte 36 does not cover the negative pressure extraction plate 35. The negative pressure extraction plate 35 creates a negative pressure through an air compressor 33 arranged outside the electrolysis tube 3, and extracts bubbles in the electrolysis tube 3.

[0045] Since the liquid sensor 34 is arranged above the negative pressure extraction plate 35, it can monitor the liquid level of the electrolyte 36 in the electrolysis tube 3 in real time. This ensures that the electrolyte 36 is not excessive or insufficient, thereby maintaining the stability and efficiency of the electrolysis process. During the electrolysis process, bubbles may rise and try to escape from the electrolyte 36. The liquid sensor 34 can indirectly monitor the movement of the bubbles by monitoring the liquid level, and adjust the working state of the negative pressure extraction plate 35 when necessary to ensure that the bubbles are effectively extracted and transmitted to the next stage. The electrolyte 36 is usually corrosive or toxic, so accurate control of the liquid level is crucial to the safety of the operator. The liquid sensor 34 provides real-time liquid level information, which helps the operator take timely measures to prevent the electrolyte 36 from overflowing or leaking;

[0046] In addition, the conductive sheet 32 ​​is arranged at the bottom of the partition 31 and is in direct contact with the electrolyte 36, providing a stable current path for the electrolysis process, which helps to accelerate the electrolysis reaction and thus more efficiently generate micro-nano bubbles. The array design of the conductive sheet 32 ​​ensures uniform distribution of current in the electrolyte 36, which avoids the problem of local overheating or uneven bubble generation caused by current concentration, thereby improving the quality and consistency of the bubbles. By providing a stable current path and uniform current distribution, the conductive sheet 32 ​​helps to reduce electrolyte loss and electrode corrosion during the electrolysis process, which extends the service life of the equipment and reduces maintenance costs.

[0047] In addition, the air compressor 33 is respectively connected to the electrolysis tube 3 and the physical stripping tube 4 to transmit the bubbles extracted by the negative pressure extraction plate 35 to the physical stripping tube 4.

[0048] Furthermore, the physical stripping tube 4 is provided with an injection part 43, a separation block 1 41 and a separation block 2 42 in sequence. The physical stripping tube 4 is divided into a pressure chamber 1 411 and a pressure chamber 2 421 by the separation block 1 41. This separation provides the necessary pressure environment for the subsequent bubble stripping process. The pressure chamber 1 411 is connected to the pressure chamber 2 421 through a guide hole 1 412 provided on the surface of the separation block 1 41 near the edge. The guide hole 1 412 is a Y-shaped structure, and the end of the guide hole 1 412 is arranged toward the middle of the separation block 2 42. The separation block 1 41 and the separation block 2 42 have arc-shaped surfaces on one side facing the injection part 43. This design enables bubbles to rebound and disperse when sprayed onto the separation block 1 41 and the separation block 2 42, thereby increasing the collision and stripping opportunities between bubbles. A guide hole 2 422 with a Y-shaped structure is provided in the separation block 2 42, and the pressure chamber 2 421 is connected to the outside through the guide hole 2 422;

[0049] The guide hole 1 412 arranged near the edge of the separation block 1 41 is a key passage connecting the pressure chamber 1 411 and the pressure chamber 2 421. The Y-shaped structure of the guide hole 1 412 and the arrangement of the end thereof toward the middle of the separation block 2 42 ensure that the bubbles can be subjected to strong physical impact and dispersion when passing through.

[0050] The peeling process of physical impact bubbles is as follows:

[0051] Initial injection and pressure increase: When the air compressor 33 extracts bubbles into the physical stripping tube 4, the injection unit 43 injects the bubbles into the pressure chamber 411 and increases the pressure in the chamber;

[0052] Bubble diversion and impact: During the pressure balance process, the bubbles in the pressure chamber 1 411 are ejected to the arc surface of the separation block 2 42 through the diversion hole 1 412. During this process, the bubbles are subjected to strong physical impact, resulting in collision and peeling between them.

[0053] Final stripping and ejection: The stripped bubbles fill the second pressure chamber 421 and are ejected outward from the second guide hole 422. During the ejection process, the bubbles are subjected to physical impact and stripping again, thereby being further refined.

[0054] The injection portion 43 is arranged in the same axial direction as the arc surface of the separation block 41 and the arc surface of the separation block 42. When bubbles are extracted into the physical stripping tube 4 through the air compressor 33, the bubbles are sprayed into the pressure chamber 411 through the injection portion 43 and the pressure in the pressure chamber 411 is increased. In the process of pressure balance, the bubbles in the pressure chamber 411 are sprayed to the arc surface of the separation block 42 through the guide hole 412, and then fill the pressure chamber 421 and then spray outward from the guide hole 422.

[0055] The injection part 43 includes a conical shell 431 and a ball 432. The conical shell 431 is connected to the air compressor 33 through an opening 4311 arranged on the side. A spherical hole 4312 connected to the opening 4311 is arranged on the other side of the conical shell 431 away from the opening 4311. The ball 432 is rotatably installed in the spherical hole 4312.

[0056] The ball 432 is provided with a flow channel running through both ends, and the flow channel is connected to the opening 4311 to guide the bubbles to flow through the opening 4311 and eject the bubbles outward through the flow channel.

[0057] In addition, a protrusion 4313 is provided on the inner side of the spherical hole 4312, and a slide groove 4325 corresponding to the protrusion 4313 is provided on the surface of the ball 432, and the protrusion 4313 is embedded in the slide groove 4325, and the protrusion 4313 and the two sides of the slide groove 4325 form a strip-shaped cavity, and a connecting hole 1 4314 connected to the strip-shaped cavity is provided on the surface of the conical shell 431, and the connecting hole 1 4314 is connected to the output end of the air compressor 2 44 provided on the outer side of the physical stripping tube 4, so as to adjust the positive and negative pressure in the strip-shaped cavity through the air compressor 2 44, so that the ball 432 rotates with the positive and negative pressure, thereby changing the direction of the bubbles ejected from the flow channel;

[0058] The flow channel includes a conical mouth 4321, a second connecting hole 4322, a strip groove 4323 and an injection hole 4324. The conical mouth 4321 and the injection hole 4324 are respectively connected to the left and right sides of the second connecting hole 4322. The strip groove 4323 extends to the surface of the ball 432 through the injection hole 4324. The conical mouth 4321 is arranged on the side of the second connecting hole 4322 close to the opening 4311. The conical mouth 4321 is a flared structure, with a large-diameter end arranged toward the opening 4311, and the inner diameter of the conical mouth 4321 is larger than the inner diameter of the opening 4311. The strip groove 4323 extends toward both sides, and the injection holes 4324 are arranged equidistantly along the length direction of the strip groove 4323.

[0059] Among them, the ball 432 is the core component of the ejection part 43, and its internal design is exquisite, aiming to guide and regulate the flow of bubbles through the flow channel. The flow channel is composed of several key parts: a conical mouth 4321, a second connecting hole 4322, a strip groove 4323 and an ejection hole 4324. These parts work together to ensure that the bubbles can be ejected from the ball 432 efficiently and controllably. The following is a detailed introduction:

[0060] The conical opening 4321 is located at one end of the flow channel, close to the opening 4311. Its expanded design not only increases the passage for bubbles to enter, but also guides the flow direction of the bubbles. The inner diameter of the conical opening 4321 is larger than the inner diameter of the opening 4311. This design helps to reduce the resistance of the bubbles when they enter the ball bearing 432, so that the bubbles can flow into the flow channel more smoothly.

[0061] The injection holes 4324 are arranged equidistantly along the length direction of the strip groove 4323 and are the channels through which the bubbles are finally ejected. The design of the injection holes 4324 ensures that the bubbles can be ejected in a uniform and controllable manner, thereby improving the accuracy and efficiency of bubble ejection;

[0062] The conical shell 431 forms a close fit with the ball 432 through its unique opening 4311, spherical hole 4312 and protrusion 4313. In particular, the interlocking design of the protrusion 4313 and the slide groove 4325 on the surface of the ball 432 not only provides support for the rotation of the ball 432, but also realizes precise control of the rotation of the ball 432 through the connection between the strip cavity and the connecting hole 4314.

[0063] When the air compressor 33 is working, it will inject bubbles into the flow channel in the ball 432 through the opening 4311. Under the guidance of the conical mouth 4321, the bubbles will smoothly flow into the connecting hole 4322 and flow along the strip groove 4323 to the injection hole 4324. At this time, the ball 432 is in a stationary state, and the injection direction of the bubbles is determined by the position of the injection hole 4324.

[0064] However, when we want to change the ejection direction of the bubbles, we need to rely on the power of the air compressor 2 44. The air compressor 2 44 injects gas into the strip-shaped cavity through the connecting hole 1 4314, thereby changing the pressure in the cavity. Due to the fitting design of the protrusion 4313 and the slide groove 4325, when the pressure in the strip-shaped cavity changes, the ball 432 will be acted upon by the force and start to rotate.

[0065] The rotation of the ball 432 changes the position of the injection hole 4324 relative to the physical stripping tube 4, thereby achieving control over the direction of bubble injection. By adjusting the output pressure of the air compressor 44, we can accurately control the rotation angle and speed of the ball 432, thereby achieving precise regulation of the bubble injection direction. By adjusting the injection direction, we can make the bubbles more evenly distributed in the physical stripping tube 4, which helps to reduce the aggregation and collision of bubbles, thereby improving the stability and uniformity of the bubbles. When the bubbles are ejected in different directions, the collision and friction between them will be more frequent and intense, which helps to further strip the bubbles and make them smaller and more uniform. At the same time, the physical impact during the stripping process also helps to increase the activity of the bubbles. By controlling the rotation of the ball 432 and the injection direction of the bubbles, we can flexibly adjust the working state and parameters of the equipment, which enables the equipment to better adapt to different application scenarios and needs, and improves its flexibility and practicality. After changing the injection direction, we can more accurately control the transmission path and collection position of the bubbles, which helps to reduce the loss and waste of bubbles and improve the utilization and efficiency of the bubbles. Embodiment 2

[0066] In this embodiment, a micro-nano bubble production process is proposed, which is applied to the micro-nano bubble production device, and includes the following steps:

[0067] S1: Pressurize water into the secondary pressurization atomization pipe 1, release the pressure of the atomized water through the pressurization pipe 1 11 and the pressurization pipe 2 12, and perform secondary pressurization in the pressurization pipe 1 11 through the air pump connected to the connecting pipe 1 111, and discharge the pressurized water into the pipe body 21;

[0068] S2: Stirring with the stirring motor 22 in the tube body 21, breaking up bubbles during the stirring process, and allowing the bubbles to be discharged into the electrolysis tube 3 when the pressure drops;

[0069] S3: By electrifying the conductive sheet 32 ​​disposed in the electrolysis tube 3, the electrolyte 36 in the partition 31 and the discharged water are electrolyzed, hydrogen and oxygen in the water are stripped, bubbles are generated, and negative pressure is created at the negative pressure extraction plate 35 by the air compressor 33, and the bubbles are extracted and sprayed on the arc surface of the separation block 41 through the injection part 43, thereby increasing the pressure in the pressure chamber 411;

[0070] S4: The bubbles in the pressure chamber 1 411 are sucked into the guide hole 1 412 through the transmission of pressure, and are ejected onto the surface of the separation block 2 42 , and then ejected outward from the guide hole 2 422 .

[0071] First, in step S1, the water is pressurized and atomized through the fine design of the secondary pressurization atomization tube 1. The secondary pressure relief process of the pressurization tube 11 and the pressurization tube 2 12 not only improves the atomization effect of the water, but also performs secondary pressurization through the air pump connected to the connecting tube 111, ensuring that the water entering the tube body 21 has sufficient pressure, providing good conditions for mixing and electrolysis in subsequent steps.

[0072] When entering step S3, after the conductive sheet 32 ​​in the electrolysis tube 3 is energized, the electrolyte 36 and the mixed water are subjected to efficient electrolysis treatment. This process not only strips the hydrogen and oxygen in the water and generates a large number of micro-nano bubbles, but also realizes the precise extraction and injection of bubbles through the negative pressure environment created by the air compressor 33 at the negative pressure extraction plate 35. This design not only improves the efficiency of bubble generation, but also ensures the uniformity and consistency of the bubbles.

[0073] Finally, in step S4, the efficient separation and injection of bubbles are achieved through the ingenious cooperation between the pressure chamber 411 and the separation blocks 41 and 42. Under the action of pressure transmission, the bubbles in the pressure chamber pass through the guide hole 412 and the guide hole 422 in turn, and finally achieve efficient external injection. This process not only improves the injection efficiency of the bubbles, but also optimizes the dispersion effect of the bubbles, so that the generated bubbles can better meet the actual application needs. Embodiment 3

[0074] like Fig.10As shown, in this embodiment, it includes a secondary pressurized atomization tube 1, a mixing tube 2, and a physical stripping tube 4. The mixing tube 2 is connected to the side of the secondary pressurized atomization tube 1, and the secondary pressurized atomization tube 1 is connected to the physical stripping tube 4. The mixing tube 2 includes a tube body 21 and a stirring motor 22. The stirring motor 22 is arrayed in the tube body 21;

[0075] The secondary pressurized atomization tube 1 comprises a pressurized tube 1 11, a pressurized tube 2 12 and a fixing block 13, the pressurized tube 1 11 and the pressurized tube 2 12 are fixed by the fixing block 13, the pressurized tube 1 11 and the pressurized tube 2 12 are respectively provided with chambers 1 and 2, the chamber 1 in the pressurized tube 1 11 is connected to the air pump through a connecting tube 1 111, and the chamber 2 in the pressurized tube 2 12 is provided with a separator 121, the chambers 1 and 2 are connected through a connecting port 112, the connecting port 112 is a flared structure, and the small-diameter end of the connecting port 112 is arranged toward the chamber 1;

[0076] The chamber 1 is an expanded structure, and the connecting pipe 111 is connected to an end with a large diameter in the chamber 1.

[0077] Based on this embodiment, a micro-nano bubble production process is also proposed, including the following steps:

[0078] S1: Pressurize water into the mixing tube 2, stir it with the stirring motor 22 in the tube body 21, break up the bubbles during the stirring process, and let the bubbles be discharged into the secondary pressurized atomization tube 1 when the pressure drops;

[0079] S2: Pressurize the secondary pressurization atomization pipe 1, release the pressure of the atomized water through the pressurization pipe 1 11 and the pressurization pipe 2 12, and perform secondary pressurization in the pressurization pipe 1 11 through the air pump connected to the connecting pipe 1 111, and discharge the pressurized water into the pipe body 21;

[0080] S3: extracting bubbles and spraying them onto the arc surface of the separation block 41 through the spraying part 43 to increase the pressure in the pressure chamber 411;

[0081] S4: The bubbles in the pressure chamber 1 411 are sucked into the guide hole 1 412 through the transmission of pressure, and are ejected onto the surface of the separation block 2 42 , and then ejected outward from the guide hole 2 422 .

[0082] In step S1, water is poured into the mixing tube 2 under pressure and stirred by the stirring motor 22, thereby effectively breaking up the bubbles in the water. This process not only promotes the initial generation of bubbles, but also makes the bubbles more evenly distributed in the mixing tube through stirring. This design helps to improve the refinement effect and stability of the bubbles in the subsequent steps.

[0083] In step S2, the secondary pressurization and atomization of water are achieved through the fine design of the secondary pressurization atomization tube 1. The coordinated use of the pressurization tube 1 11 and the pressurization tube 2 12, as well as the segmentation and refinement of the gas by the separator 121, jointly promote the generation of micro-nano bubbles. This process not only improves the refinement of the bubbles, but also enhances the stability and storage time of the bubbles.

[0084] In steps S3 and S4, the efficient stripping and ejection of bubbles is achieved through the ingenious design of the physical stripping tube 4. The coordinated use of the pressure chamber 1 411 and the separation block 1 41 and the separation block 2 42, as well as the ingenious design of the guide hole 1 412 and the guide hole 2 422, jointly promote the efficient separation of bubbles in the tube and their ejection outward. This process not only improves the ejection efficiency of the bubbles, but also optimizes the dispersion effect of the bubbles, making the generated bubbles smaller, more uniform and more stable.

[0085] The process steps in Example 3 are adjusted and optimized compared with those in Example 2. By connecting the mixing tube 2 to the side of the secondary pressurized atomizing tube 1 and omitting the use of the electrolysis tube 3, the process steps are simplified and the equipment cost is reduced. At the same time, this adjustment does not sacrifice the refinement effect and stability of the bubbles, but improves the bubble generation efficiency and injection effect by optimizing the equipment structure and process steps.

[0086] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
