Description

Technical Field

[0001] This invention relates to the field of environmental protection technology, specifically to a structure and method for increasing the solubility of gases in liquids. Background Technology

[0002] Increasing the solubility of gases in liquids is crucial for fields such as pharmaceuticals, chemicals, and environmental protection. For example, in pharmaceutical manufacturing, some drugs require gas dissolution to form particles, improving their bioavailability and efficacy; in chemical reactions, gas solubility is used to control reaction rates and product formation; and in environmental protection, gas solubility is used to clean polluted water or gases. Furthermore, increasing gas solubility in liquids can also be used to prepare highly efficient coupled reaction catalysts and improve the dyeing effects of fiber products. Therefore, studying gas solubility in liquids is of great significance and has broad application prospects in engineering.

[0003] Increasing the pressure of a liquid is a common method to increase the solubility of gases in a liquid. This is because the amount of gas dissolved in a liquid is directly proportional to its partial pressure, according to Henry's Law. Therefore, increasing the pressure of a gas in a liquid increases its partial pressure, thereby increasing its solubility. This is because when the partial pressure of a gas increases, gas molecules collide with liquid molecules more frequently at the liquid-gas interface. These collisions generate pressure, sufficient to force gas molecules into the liquid. This increases the number of gas molecules in the liquid, thus increasing its solubility.

[0004] Increasing the contact area between a liquid and a gas is a common method to improve the solubility of a gas in a liquid. The basic principle is that the larger the contact area between the liquid and the gas, the more likely gas molecules are to enter the liquid and interact with liquid molecules. Increasing the contact area between the liquid and the gas can be achieved by introducing a gas dispersant or a vortex generator.

[0005] When a gas dispersant is introduced into a liquid, it forms bubbles in the liquid, increasing the contact area between the liquid and the gas. At this time, the liquid comes into contact with the gas through the surface area of ​​the bubbles, thereby exchanging gas molecules and increasing the solubility of the gas in the liquid.

[0006] A vortex generator can increase the stirring intensity of a liquid, creating a vortex flow and increasing the contact area between the liquid and the gas. This increases the dispersion of gas molecules within the liquid, allowing them to be absorbed more quickly and improving the solubility of the gas. Increasing the contact area between the liquid and gas enhances their interaction, thereby increasing the solubility of the gas in the liquid. The solubility of gases in liquids can also be improved by lowering the temperature, increasing the viscosity of the liquid, or altering the chemical properties of the solvent.

[0007] However, among the above methods for improving solubility, using a vortex generator to provide mechanical kinetic energy requires daily maintenance and upkeep of the vortex generator equipment, and the long-term use results in a large amount of electrical energy consumption. Furthermore, methods such as adding gas dispersants, lowering the temperature, increasing the viscosity of the liquid, or changing the chemical properties of the solvent require a large amount of chemical additives that need to be added over a long period of time, which increases the cost of increasing the solubility of gas in liquid. Summary of the Invention

[0008] The purpose of this invention is to provide a structure and method for increasing the solubility of gas in liquid, in order to solve the problems mentioned in the background art, which propose to increase solubility by using a vortex generator to provide mechanical kinetic energy. This method requires daily maintenance and upkeep of the vortex generator, and the long-term use results in a large amount of electrical energy consumption. Furthermore, methods such as adding gas dispersants, lowering the temperature, increasing the viscosity of the liquid, or changing the chemical properties of the solvent require the long-term addition of large amounts of chemical additives, which increases the cost of increasing the solubility of gas in liquid.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A structure for increasing the solubility of a gas in a liquid includes an aeration head body. One end of the aeration head body has an outlet connector. An aeration pipe is axially inserted inside the aeration head body. The outlet connector abuts against one end of the aeration pipe, forming a seal. An inlet connector is located inside the aeration head body, communicating with the interior of the aeration pipe. Multiple water inlet channels are formed within the inlet connector. Multiple rubber rings are fixedly connected inside the aeration head body. Micro-gaps are formed between the inner sides of the rubber rings and the outer wall of the aeration pipe, communicating with the interior of the water inlet channels. An aeration hole is formed through the middle of the aeration pipe, and multiple nanopores are formed within the aeration pipe for the flow of gas-liquid mixtures.

[0011] Preferably, the aeration head body has multiple grooves, and a rubber ring is fixedly connected in the grooves. Both ends of the outer side of the aeration head body are provided with interface threads for connecting external water pipes.

[0012] Preferably, the explosion head body is tubular, with both the outlet connector and the inlet connector inserted into the explosion head body. Multiple explosion grooves are formed by fitting the outer wall of the explosion pipe and the inner wall of the explosion head body together. Multiple air outlets are provided in the outlet connector, and the air outlets communicate with the interior of the explosion grooves. The outlet connector includes a sealing cap integrally formed therewith. One end of the explosion pipe is inserted into the sealing cap, and the inner wall of the sealing cap blocks one end of the explosion pipe. The air outlet is located between the explosion head body and the sealing cap.

[0013] Preferably, the interface between the sealing cover and the aeration pipe has an adjustment channel, the aeration pipe is inserted into the adjustment channel, the adjustment channel includes a sealing port and an adjustment port, the sealing port is opened at the end of the adjustment channel and is tightly sealed to the outer wall of the aeration pipe, the adjustment port is opened inside the adjustment channel, and the aeration pipe is inserted into the adjustment port.

[0014] Preferably, the air outlet includes a short connection hole formed between the air vent head body and the sealing cover. The air outlet communicates with the interior of the air vent groove through the short connection hole. A wedge-shaped interface is provided in the inlet connector, and the wedge-shaped interface communicates with the interior of the air vent pipe.

[0015] Preferably, the aeration head body is disc-shaped, and the outlet connector and the inlet connector are integrally formed with the aeration head body. A liquid storage cavity is formed between the aeration pipe and the aeration head body. A liquid outlet groove is opened in the aeration head body. The outlet connector and the water inlet channel are connected to the inside of the liquid outlet groove. An outlet interface is opened at one end of the aeration head body.

[0016] A method for increasing the solubility of a gas in a liquid includes the following steps:

[0017] S1. Screw the aeration head body into the external water supply pipe and water outlet pipe through its external interface thread, so that the aeration head body is threadedly connected to the external water supply pipe and water outlet pipe. The water supply pipe is connected to the equipment for increasing the gas content in the solution and the water pump in the prior art, thus completing the installation of the aeration head body.

[0018] S2. By increasing the gas content in the solution and starting the water pump, gas is added to the water to form a gas-liquid mixture. The gas-liquid mixture with a certain flow rate is connected to the inlet connector and flows into the explosion head body and the explosion pipe respectively. The fluid passing through the micro gap will create a low-pressure area due to the increased flow rate. A pressure difference is generated on both sides of the explosion pipe, causing the fluid in the explosion pipe to flow into the explosion head body.

[0019] S3. When the gas-liquid mixture passes through the nanopores of the aeration pipe, it is divided by multiple nanopores to form micro-nano bubbles and a gas-liquid mixture fluid of micro-nano bubbles and micro-nano liquid, which maximizes the contact area between gas and water, improves the solubility of gas in solution, and finally flows out through the outlet connector.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] By combining the detonation head body and the detonation pipe, a gas-liquid mixture with a preset flow rate is introduced into the inlet connector and flows into the detonation head body and the detonation pipe respectively. The fluid passing through the micro gaps will create a low-pressure zone due to the increased flow rate, and a pressure difference will be generated on both sides of the detonation pipe, causing the fluid in the detonation pipe to flow into the interior of the detonation head body. The gas-liquid mixture is split through multiple nanopores in the detonation pipe to form micro-nano bubbles and gas-liquid mixtures of micro-nano bubbles and micro-nano liquids. This maximizes the contact area between the gas and water and improves the solubility of the gas in the solution. Compared with the existing technology, it eliminates the need for eddy current generators and the addition of large amounts of chemical additives such as gas dispersants, eliminates the need for daily maintenance of the detonation head body, and reduces the cost of improving the solubility of the gas in the liquid.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figures 1-3 The present invention provides:

[0028] A structure for increasing the solubility of a gas in a liquid includes an aeration head body 2, with an outlet connector 1 at one end of the aeration head body 2. An aeration pipe 3 is axially inserted inside the aeration head body 2, with the outlet connector 1 abutting against and forming a seal with one end of the aeration pipe 3. An inlet connector 5 is provided inside the aeration head body 2, communicating with the interior of the aeration pipe 3. Multiple water inlet channels 5a are formed inside the inlet connector 5. Multiple rubber rings 4 are fixedly connected inside the aeration head body 2, with micro-gaps 6 formed between the inner side of the rubber rings 4 and the outer wall of the aeration pipe 3. The micro-gaps 6 communicate with the interior of the water inlet channels 5a. An aeration hole 3a is provided through the middle of the pipe 3. Multiple nanopores are provided through the aeration pipe 3 for the flow of gas-liquid mixture. Multiple grooves are provided in the aeration head body 2. Rubber rings 4 are fixedly connected in the grooves. Both ends of the outer side of the aeration head body 2 are provided with interface threads 7. The interface threads 7 are used to connect to external water pipes. They can be threaded to water supply pipes and water outlet pipes for water supply through the interface threads 7. The water supply pipes and water outlet pipes are provided with internal threads that are compatible with the interface threads 7. The water supply pipes are internally connected to the equipment for increasing the gas content in the solution and the water pump in the prior art using the pipe connection method commonly used in the prior art.

[0029] The detonator body 2 is tubular. Both the outlet connector 1 and the inlet connector 5 are inserted into the detonator body 2. Multiple detonation grooves 2c are formed between the outer wall of the detonation pipe 3 and the inner wall of the detonator body 2. Multiple outlet ports 1a are provided inside the outlet connector 1, communicating with the interior of the detonation grooves 2c. The outlet connector 1 includes an integrally formed sealing cap 1b. One end of the detonation pipe 3 is inserted into the sealing cap 1b, and the inner wall of the sealing cap 1b seals one end of the detonation pipe 3. The outlet ports 1a are located between the detonator body 2 and the sealing cap 1b. An adjustment channel 1c is provided at the interface between the sealing cap 1b and the detonation pipe 3. The detonation pipe 3 is inserted into the adjustment channel 1c. The adjustment channel 1c includes a sealing port and an adjustment... The joint consists of two parts: a sealing port located at the end of the regulating channel 1c, which is tightly sealed to the outer wall of the aeration pipe 3; and an regulating port located inside the regulating channel 1c. The aeration pipe 3 is inserted into the regulating port, and the relative sliding between the aeration pipe 3 and the regulating channel 1c adjusts the space between the aeration pipe 3 and the regulating port, thereby adjusting the pressure of the gas-liquid mixture inside the aeration pipe 3 and further controlling the solubility of the gas in the aqueous solution. The outlet 1a includes a short-circuit through hole 1d formed between the aeration head body 2 and the sealing cover 1b. The outlet 1a communicates with the interior of the aeration tank 2c through the short-circuit through hole 1d. A wedge-shaped interface 5b is provided inside the inlet connector 5, and the wedge-shaped interface 5b communicates with the interior of the aeration pipe 3.

[0030] Working principle: (Reference) Figure 1As shown, by using existing technology to increase the gas content in the solution and starting the water pump, gas is added to the water to form a gas-liquid mixture. This gas-liquid mixture is input from the inlet connector 5 and passes through the aeration head body 2 and aeration pipe 3 to form a large number of micro-nano bubbles. The gas-liquid mixture flows out from the outlet, forming a milky white "gas-in-water" fluid. When the gas and aqueous solution flow in from the inlet connector 5 at a certain flow rate, they enter the aeration pipe 3 and aeration tank 2c through the wedge-shaped interface 5b and the water inlet channel 5a, respectively. After the gas-liquid mixture enters the aeration tank 2c through the water inlet channel 5a, the aeration tank 2c and the outer side of the aeration pipe 3 are filled with gas. The gas-liquid mixture is filled with rubber ring 4. When it flows through the rubber ring 4, the flow velocity increases due to compression. The pressure between the outside of the aeration pipe 3 and the rubber ring 4 is less than the pressure inside the aeration hole 3a. At this time, due to the pressure difference between the two sides of the aeration pipe 3, the gas-liquid mixture inside the aeration hole 3a tends to flow into the aeration tank 2c with lower pressure. Utilizing the nanopores of the aeration pipe 3, the gas-liquid mixture forms a large number of tiny bubbles and micro-nano-sized aqueous fluid after passing through the aeration pipe 3, greatly increasing the contact area between the gas and the aqueous solution. The solubility of the gas in water is also correspondingly increased, forming a "water-in-gas" fluid carrying a large number of tiny bubbles. Due to the presence of a large number of bubbles in the liquid, the water-in-gas appears as a milky white fluid. The application of this method can make the solubility of the gas in water higher than that of existing technologies. When the pressure inside the aeration pipe 3 is too high, the gas-liquid mixture flows from the aeration hole 3a through the aeration pipe 3 into the regulating channel 1c, further through the short-connection through hole 1d, and out from the outlet 1a.

[0031] It should be noted that the nanopores are formed by the porous materials of the aeration pipe 3 itself, such as porous ceramic materials, porous metal materials and porous polymer materials. Specific porous ceramic materials include corundum sand, silicon carbide, cordierite, etc., porous metal materials include copper, silver, titanium, nickel and their alloys and stainless steel, etc., and porous polymer materials include bacterial cellulose, activated carbon and zeolite, etc.

[0032] A method for increasing the solubility of a gas in a liquid includes the following steps:

[0033] S1. Screw the aeration head body 2 into the external water supply pipe and water outlet pipe through the external interface thread 7, so that the aeration head body 2 is threadedly connected to the external water supply pipe and water outlet pipe. The water supply pipe is connected to the equipment for increasing the gas content in the solution and the water pump in the prior art, thus completing the installation of the aeration head body 2.

[0034] S2. By increasing the gas content in the solution and starting the water pump, gas is added to the water to form a gas-liquid mixture. The gas-liquid mixture with a certain flow rate is connected to the inlet connector 5 and flows into the aeration head body 2 and the aeration pipe 3 respectively. The fluid passing through the micro gap 6 will cause a low-pressure area due to the increased flow rate. A pressure difference is generated on both sides of the aeration pipe 3, causing the fluid in the aeration pipe 3 to flow into the interior of the aeration head body 2.

[0035] S3. When the gas-liquid mixture passes through the nanopores of the aeration pipe 3, it is divided by multiple nanopores to form micro-nano bubbles and a gas-liquid mixture fluid of micro-nano bubbles and micro-nano liquid, which maximizes the contact area between gas and water, improves the solubility of gas in solution, and finally flows out through the outlet connector 1.

[0036] According to the continuity theorem, when a liquid flows through an unbranched pipe, the flow rate across each cross-section is always equal. Daniel Bernoulli proposed Bernoulli's principle in 1726, which is one of the fundamental equations of fluid dynamics. Bernoulli's equation is the dynamic equation for steady flow of an ideal fluid. It explains that in the case of an incompressible fluid flowing with negligible viscous losses, the sum of the pressure potential energy, kinetic energy, and potential energy at any two points on a streamline remains constant. Essentially, it represents the conservation of the fluid's mechanical energy, expressed by the equation: +pgh = constant, where p is the pressure energy per unit volume of fluid. Here, pgh represents the kinetic energy per unit volume of fluid, and pgh represents the gravitational potential energy per unit volume of fluid. When fluids flow at the same height, their gravitational potential energy is the same. At this point, a higher fluid velocity results in lower pressure. In this invention, a gas-liquid mixture is pushed into an aeration head, and then a portion of the gas-liquid mixture is passed through porous micro / nanomaterials to form a micron-sized fluid. By increasing the contact area between water and hydrogen, the solubility of the gas in water is increased.

[0037] According to Bernoulli's equation, when a fluid passes through an obstacle, the fluid bends outward along the obstacle, and the flow velocity decreases on the side of the obstacle, forming a high-pressure zone, such as... Figure 3 As shown, when a fluid passes over an obstacle, the flow velocity increases, creating a low-pressure zone. At this time, a pressure difference is formed on both sides of the pipe wall. When the pipe wall is a porous material, the fluid outside the pipe can enter the pipe through the pressure difference. The gas-liquid mixture can form a micron-sized fluid, thus increasing the solubility of the gas in the solution.

[0038] Example 2: Please refer to Figures 1-3 Based on Embodiment 1, the tubular detonator body 2 is replaced with a disc-shaped detonator body 2, and the detonation pipe 3 also changes to a disc shape along with the detonator body 2, specifically:

[0039] The detonator body 2 is disc-shaped. The outlet connector 1 and the inlet connector 5 are integrally formed with the detonator body 2. The detonation pipe 3 and the detonator body 2 form a liquid storage chamber 3b. The detonator body 2 has a liquid outlet groove 8. The outlet connector 1 and the water inlet channel 5a are both connected to the inside of the liquid outlet groove 8. One end of the detonator body 2 has an outlet interface 2a.

[0040] Working principle: After the gas-liquid mixture flows into the inlet connector 5, part of the gas-liquid mixture will enter the outlet interface 2a. The gas-liquid mixture will flow into the storage chamber 3b through the venting hole 3a. When the gas-liquid mixture in the outlet interface 2a passes through the annular rubber ring 4, the fluid velocity increases and the pressure decreases as it passes through the extrusion section. Under the pressure difference, the gas-liquid mixture in the storage chamber 3b will permeate into the outlet interface 2a through the nanopores in the venting pipe 3. In this process, it will be dispersed into nano / micron-sized gas bubbles. After passing through multiple layers of annular rubber rings 4, the mixture in the outlet interface 2a will become a gas-liquid mixture with a higher gas concentration, gradually forming a "gas-liquid" type fluid. It will then flow into the outlet tank 8 from the inlet channel 5a, and be transferred to the outlet connector 1 from the outlet tank 8, and finally flow out from the outlet connector 1.

[0041] Compared with the technical solution of Embodiment 1, replacing the tubular gas-venting head body 2 with the disc-shaped gas-venting head body 2 increases the contact area of ​​the gas-liquid mixture and slightly increases the solubility of the gas in the liquid. However, the tubular gas-venting head body 2 is smaller in size and easier to carry.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
