Abstract
Description
Technical Field
[0001] The present invention relates to the field of micro-nano bubble technology, and more specifically to a polymer nano-scale micro-bubble generating device and application thereof. Background Art
[0002] With the rapid development of science and technology, microbubble technology is being used more and more widely in many fields. Microbubbles, especially nano-scale microbubbles, have shown great application potential in many industries such as water treatment, medical treatment, cosmetics and food processing due to their unique physical and chemical properties.
[0003] In the field of water treatment, microbubble technology has attracted much attention due to its efficient oxygen transmission capacity and adsorption capacity for pollutants. Traditional water treatment methods often fail to achieve the ideal dissolved oxygen content and organic matter decomposition effect, while microbubble technology can increase the dissolved oxygen content in the water and accelerate the decomposition process of organic matter, thereby improving the self-purification capacity and water quality of the water. In addition, microbubbles can also effectively remove suspended matter, heavy metal ions and organic pollutants in the water, providing strong support for the purification and protection of water bodies.
[0004] In the medical field, microbubble technology also shows great application prospects. As a drug carrier, microbubbles can carry and stably deliver drugs to the lesion site, achieving precise drug delivery and targeted treatment. This drug delivery method can not only improve the utilization rate and therapeutic effect of drugs, but also reduce the side effects of drugs and the pain of patients. In addition, microbubbles can also be used as a diagnostic tool for the enhancement of medical images and the location of lesions, providing doctors with more accurate and reliable information for diagnosis and treatment.
[0005] The application of microbubble technology is also of great significance in the cosmetics and food processing industries. In cosmetics, microbubbles can increase the stability and performance of products, improve the product's use effect and user experience. In food processing, microbubbles can improve the taste and texture of food, and improve the quality and nutritional value of food. In addition, microbubbles can also be used to preserve food and extend its shelf life, providing new ideas and methods for the development and innovation of the food industry.
[0006] However, despite the broad application prospects of microbubble technology in many fields, existing microbubble generating equipment still has some problems and shortcomings. For example, some equipment cannot effectively control the size and stability of the bubbles when generating microbubbles, resulting in uneven size and poor stability of the generated bubbles, which is difficult to meet the needs of practical applications. In addition, some equipment needs to be shut down when adjusting the bubble size, which not only affects production efficiency, but also increases the maintenance cost and complexity of the equipment. Summary of the invention
[0007] 1. Technical issues to be solved
[0008] In view of the problems existing in the prior art, the present invention provides a device and application of a polymer nano-scale microbubble generator. It uses the Venturi effect and Bernoulli's theorem to accurately control the size and stability of microbubbles by adjusting the fluid pressure and viscosity. The viscosity adjustment component adopts an innovative electromagnet to control the opening and closing technology of the liquid hole to achieve the precise addition of the viscosity regulator, thereby adjusting the liquid viscosity and optimizing the bubble size. The air intake component ensures that the gas is evenly distributed and forms tiny bubbles through the microporous medium layer. The device is widely used in water treatment, medical treatment, cosmetics, food processing and other industries to effectively increase the dissolved oxygen content, accelerate the decomposition of organic matter, serve as a drug carrier, and improve product stability and performance. Its continuous online adjustment function does not require shutdown adjustment and has a wide range of applicability.
[0009] 2. Technical solution
[0010] To solve the above problems, the present invention adopts the following technical solutions.
[0011] A device for generating microbubbles based on polymer nanometer scale, comprising:
[0012] A polymer liquid container, used for storing the polymer solution to be processed;
[0013] A pressure regulating pump, connected to the polymer liquid container, is used to adjust the pressure of the polymer solution to control the size and stability of the microbubbles;
[0014] A microporous structure generator, wherein the liquid inlet end is connected to a pressure regulating pump through a liquid infusion tube, and the liquid outlet end is connected to a collecting container through a liquid outlet tube, wherein a first solenoid valve is installed on the liquid infusion tube, and a second solenoid valve is installed on the liquid outlet tube;
[0015] A viscosity regulating component, mounted on the microporous structure generator, is used to provide a viscosity regulator to control the size of microbubbles;
[0016] The air inlet assembly is installed on the microporous structure generator and is used to provide the gas required for generating microbubbles.
[0017] As a further improvement of the present invention, the microporous structure generator includes a fluid acceleration part, a gas-liquid mixing part and a fluid outlet part from the liquid inlet end to the liquid outlet end. The inner diameter of the fluid acceleration part gradually decreases along the liquid direction, the inner diameter of the gas-liquid mixing part remains unchanged, and the inner diameter of the fluid outlet part gradually increases along the liquid direction, and the increase angle is smaller than the decrease angle of the fluid acceleration part. According to the Venturi effect and Bernoulli's theorem, the cross-sectional area of the flow path is changed to increase the flow rate, reduce the pressure, and generate microbubbles. When a fluid with a certain flow rate enters the liquid inlet end and begins to accelerate to the gas-liquid mixing part through the fluid acceleration part, the fluid reaches the highest flow rate. At this time, the pressure becomes smaller, and a pressure difference is formed between the fluid inlet part and the gas-liquid mixing part. This pressure difference becomes suction. Under the action of this suction, the gas is continuously crushed and sucked into the fluid through the pores by the fluid, and becomes a gas-liquid mixture that flows out of the gas-liquid mixing part and then sprays out through the fluid outlet part. This gas-liquid mixture will contain a large number of microbubbles and nanobubbles.
[0018] As a further improvement of the present invention, the gas-liquid mixing part includes a hollow ring, an annular cavity is opened inside the hollow ring, a plurality of liquid outlet holes distributed in a circular array are opened on the inner wall of the hollow ring, a plurality of liquid holes corresponding to the liquid outlet holes are opened on the microporous structure generator, a control column is slidably installed at the opening of the liquid hole, and a plurality of electromagnets corresponding to the control column are fixedly installed on the hollow ring. The opening and closing of the liquid hole are realized by controlling the control column by the electromagnet, so that the viscosity regulator is added to the inside of the microporous structure generator to control the viscosity of the liquid, and then the size and stability of the bubbles are controlled.
[0019] As a further improvement of the present invention, the hollow ring is connected to a liquid pump through a liquid filling pipe, the liquid pump is connected to a viscosity regulator container, and a flow monitoring meter is installed on the liquid filling pipe.
[0020] As a further improvement of the present invention, the air intake component includes a gas container, the gas container is connected to an air pump, the air pump is connected to the microporous structure generator through an inflation tube, a flow monitoring meter is installed on the inflation tube, an annular air chamber is opened in the microporous structure generator, and the inflation tube is connected to the annular air chamber, and the microporous structure generator is also provided with a plurality of air holes distributed in an annular array, and the air holes are connected to the annular air chamber.
[0021] As a further improvement of the present invention, a microporous medium layer is fixedly connected to the pore opening, and is made of one of ceramics, metal powder sintered body, and polymer membrane, and the pore size is less than 2μm. The microporous medium layer distributes the gas so that it can form smaller and more uniform microbubbles when entering the liquid.
[0022] As a further improvement of the present invention, the position of the liquid hole is located at the junction of the fluid acceleration part and the gas-liquid mixing part, and the position of the air hole is located in the middle area of the gas-liquid mixing part. When the viscosity regulator is added to the liquid hole at this position, on the one hand, part of the liquid will not easily enter the liquid hole due to the pressure relationship, and on the other hand, there can be a longer path for sufficient and uniform mixing with the liquid, thereby improving the accuracy of liquid viscosity control and making the quality of the formed microbubbles better. The position of the air hole not only assists the viscosity regulator to mix evenly with the liquid, but also allows a certain amount of time for a large number of microbubbles to be formed in the liquid.
[0023] As a further improvement of the present invention, the control column includes a main column, a liquid groove is provided at one end of the main column close to the electromagnet, a release hole connected to the liquid groove is provided at one end of the main column close to the air hole, and a limiting slider is fixedly connected to one side end of the main column, a limiting groove matching the limiting slider is provided on the inner wall of the liquid hole, and the limiting slider is slidably installed in the limiting groove, when the main column is located on the inner side of the liquid hole, the release hole is blocked by the inner wall of the liquid hole, and the viscosity regulator therein cannot flow out, and when the main column moves to the outside of the liquid hole, the viscosity regulator can flow out through the release hole, and the position is facing the outlet direction.
[0024] As a further improvement of the present invention, the outlet of the release hole is inclined along the central axis direction close to the microporous structure generator and is fixedly connected to a dispersion net, and the end of the main column away from the electromagnet is fixedly connected to a sealing ring. The viscosity regulator sprayed out at an angle is more conducive to mixing with the liquid, and the sealing ring can play a role of pre-dispersion before mixing, so that the viscosity regulator and liquid are mixed more fully and evenly.
[0025] An application based on a polymer nanoscale microbubble generating device, comprising:
[0026] Used for water treatment and purification, increasing the dissolved oxygen content in water and accelerating the decomposition of organic matter;
[0027] Used in the medical field as a drug carrier or diagnostic tool;
[0028] Used in the cosmetics and food processing industries to improve product stability and performance.
[0029] 3. Beneficial effects

[0031] (1) The present invention uses polymer liquid as the working medium and combines components such as a pressure regulating pump and a microporous structure generator to achieve effective control of the size and stability of the generated bubbles.

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.
[0042] Example:
[0043] See also Figure 1-6 , a device for generating microbubbles based on polymer nanometer scale, comprising:
[0044] A polymer liquid container 1, used for storing the polymer solution to be processed;
[0045] A pressure regulating pump 2, connected to the polymer liquid container 1, for regulating the pressure of the polymer solution to control the size and stability of the microbubbles;
[0046] A microporous structure generator 5, the liquid inlet end is connected to the pressure regulating pump 2 through the liquid infusion tube 3, the liquid outlet end is connected to the collection container through the liquid outlet tube 6, the liquid infusion tube 3 is installed with a solenoid valve 1 4, and the liquid outlet tube 6 is installed with a solenoid valve 2 7;
[0047] A viscosity adjustment component, mounted on the microporous structure generator 5, for providing a viscosity adjuster to control the size of microbubbles;
[0048] The air inlet assembly is installed on the microporous structure generator 5 and is used to provide the gas required for generating microbubbles.
[0049] The microporous structure generator 5 includes a fluid acceleration part 501, a gas-liquid mixing part 502 and a fluid outlet part 503 from the liquid inlet end to the liquid outlet end. The inner diameter of the fluid acceleration part 501 gradually decreases along the liquid direction, the inner diameter of the gas-liquid mixing part 502 remains unchanged, and the inner diameter of the fluid outlet part 503 gradually increases along the liquid direction, and the increase angle is smaller than the decrease angle of the fluid acceleration part 501. According to the Venturi effect and Bernoulli's theorem, the cross-sectional area of the flow path is changed to increase the flow rate, reduce the pressure, and generate microbubbles. When a fluid with a certain flow rate enters the liquid inlet end and begins to accelerate to the gas-liquid mixing part 502 through the fluid acceleration part 501, the fluid reaches the highest flow rate. At this time, the pressure decreases, and a pressure difference is formed between the fluid inlet part and the gas-liquid mixing part. This pressure difference becomes suction. Under the action of this suction, the gas is continuously crushed and sucked into the fluid through the pores 19 by the fluid, and becomes a gas-liquid mixture that flows out of the gas-liquid mixing part 502 and then sprays out through the fluid outlet part 503. This gas-liquid mixture will contain a large number of microbubbles and nanobubbles.
[0050] The gas-liquid mixing section 502 includes a hollow ring 8, an annular cavity is provided inside the hollow ring 8, a plurality of liquid outlet holes distributed in a circular array are provided on the inner wall of the hollow ring 8, a plurality of liquid holes 20 corresponding to the liquid outlet holes are provided on the microporous structure generator 5, a control column 21 is slidably installed at the opening of the liquid hole 20, and a plurality of electromagnets 22 corresponding to the control column 21 are fixedly installed on the hollow ring 8. The opening and closing of the liquid hole 20 are realized by controlling the control column 21 by the electromagnet 22, so that the viscosity regulator is added to the inside of the microporous structure generator 5 to control the viscosity of the liquid, thereby controlling the size and stability of the bubbles.
[0051] The hollow ring 8 is connected to a liquid pump 10 through a liquid filling pipe 12 , the liquid pump 10 is connected to a viscosity regulator container 9 , and a flow rate monitoring meter 11 is installed on the liquid filling pipe 12 .
[0052] The air intake component includes a gas container 13, which is connected to an air pump 14. The air pump 14 is connected to the microporous structure generator 5 through an air filling tube 15. A flow monitor 16 is installed on the air filling tube 15. An annular air chamber 17 is provided in the microporous structure generator 5, and the air filling tube 15 is connected to the annular air chamber 17. A plurality of air holes 19 distributed in an annular array are also provided inside the microporous structure generator 5, and the air holes 19 are connected to the annular air chamber 17.
[0053] A microporous medium layer 18 is fixedly connected to the opening of the pore 19, and is made of one of ceramics, metal powder sintered body, and polymer membrane, and the pore size is less than 2μm. The microporous medium layer 18 distributes the gas so that it can form smaller and more uniform microbubbles when entering the liquid.
[0054] The position of the liquid hole 20 is located at the junction of the fluid acceleration part 501 and the gas-liquid mixing part 502, and the position of the air hole 19 is located in the middle area of the gas-liquid mixing part 502. The viscosity regulator is added to the liquid hole 20 at this position. On the one hand, part of the liquid will not easily enter the liquid hole 20 due to the pressure relationship. On the other hand, there is a longer path for sufficient and uniform mixing with the liquid, which improves the accuracy of liquid viscosity control and makes the quality of the formed microbubbles better. The position of the air hole 19 not only assists the viscosity regulator to mix evenly with the liquid, but also has a certain amount of time to form a large number of microbubbles in the liquid.
[0055] The control column 21 includes a main column 2101, and a liquid groove 2102 is provided at one end of the main column 2101 close to the electromagnet 22, and a release hole 2103 connected to the liquid groove 2102 is provided at one end of the main column 2101 close to the air hole 19. A limiting slider 2105 is also fixedly connected to one side end of the main column 2101, and a limiting groove matching the limiting slider 2105 is provided on the inner wall of the liquid hole 20, and the limiting slider 2105 is slidably installed in the limiting groove. When the main column 2101 is located on the inner side of the liquid hole 20, the release hole 2103 is blocked by the inner wall of the liquid hole 20, and the viscosity regulator therein cannot flow out. When the main column 2101 moves to the outside of the liquid hole 20, the viscosity regulator can flow out through the release hole 2103, and the position is toward the outlet direction.
[0056] The outlet of the release hole 2103 is inclined along the central axis direction close to the microporous structure generator 5 and is fixedly connected to a dispersion net 2104. The end of the main column 2101 away from the electromagnet 22 is fixedly connected to a sealing ring 2106. The viscosity regulator sprayed out at an angle is more conducive to mixing with the liquid, and the sealing ring 2106 can play a role of pre-dispersion before mixing, so that the viscosity regulator and liquid are mixed more fully and evenly.
[0057] Working principle:
[0058] The infusion tube 3 transfers the polymer liquid in the polymer liquid container 1 to the microporous structure generator 5 by adjusting the liquid pressure. According to the Venturi effect and Bernoulli's theorem, the cross-sectional area of the flow path is changed to increase the flow rate, reduce the pressure, and generate microbubbles. When a fluid with a certain flow rate enters the liquid inlet end, the fluid reaches the highest flow rate when it begins to accelerate through the fluid acceleration part 501 to the gas-liquid mixing part 502. At this time, the pressure becomes smaller, and a pressure difference is formed between the fluid inlet part and the gas-liquid mixing part. This pressure difference becomes suction. Under the action of this suction, the gas is continuously crushed and sucked into the flow through the pores 19 by the fluid. The liquid in the liquid body is converted into a gas-liquid mixture and flows out of the gas-liquid mixing part 502, and then is ejected through the fluid outlet part 503. This gas-liquid mixture will contain a large number of microbubbles and nanobubbles. When the size of the bubbles needs to be adjusted, the electromagnet 22 and the liquid pump 10 are started synchronously, and the viscosity regulator is transported inside the microporous structure generator 5 in the liquid hole 20. Since the viscosity regulator is impacted and mixed from multiple angles toward the inside, it has a better mixing effect with the liquid compared to direct addition and mixing, and the change in liquid viscosity is linear, so that the size of the generated bubbles is relatively close, avoiding the situation where the bubble size is greatly different.
[0059] It is worth noting that in actual situations, the change in liquid viscosity and bubble size are not necessarily positively correlated. To a certain extent, the greater the viscosity of the liquid, the greater the interaction force and friction between its molecules, which may limit the expansion of bubbles in the liquid, resulting in a decrease in bubble size. However, it is also possible that after the viscosity increases, the vortex of the liquid decreases, which is conducive to the formation of large bubbles. At the same time, the increase in viscosity may promote the merger of bubbles and prevent the splitting of large bubbles, thereby increasing the size of the bubbles. Therefore, the size control by the viscosity regulator should be specifically debugged according to the actual situation. The debugging results can guide the effective control of the size of the bubbles during actual use. However, the increase in viscosity can improve the stability of the bubbles within a certain range. The method of using a viscosity regulator to control the bubble size in the present invention usually does not cause significant changes in other properties of the liquid, such as surface tension, so it is easier to control the size of the bubbles. Generally, high molecular polymers are used as viscosity regulators, such as polyvinyl alcohol, polyacrylamide, etc. These polymers can form a network structure in the fluid, thereby increasing the viscosity of the fluid.
[0060] The present invention can achieve continuous online adjustment of the size of generated bubbles, thereby achieving continuous output of highly stable nano-micro bubbles without stopping the machine, without the need to adjust the polymer liquid of a specified viscosity in advance, and the applicability of the present invention is wider than that of the prior art.

[0065] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
