[0001] This invention relates to the field of gas-liquid mixing equipment technology, and specifically to a gas-liquid mixing device and method based on dynamic dissolution. Background Technology

[0002] Gas-liquid mixing refers to injecting a special gas into a liquid, allowing the gas to fully mix and react with the liquid. This reaction method is used in many chemical fields, primarily to achieve a complete reaction between the gas and the corresponding liquid to obtain desired derivatives. Existing gas-liquid mixing technologies mainly include point jet mixing, internal mixing atomizing nozzle devices, and gas-liquid mixing pumps. These methods directly mix the gas and liquid through nozzles, jets, or external mixing pumps, commonly using reaction vessels and reactors. However, these gas-liquid mixing methods are simplistic and crude, with a limited number of exhaust points within the liquid and a relatively small contact area between the gas and liquid, resulting in poor mixing reaction effects and low mixing efficiency. Summary of the Invention

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0028] The following is combined Figures 1 to 2 The following describes embodiments of the present invention.

[0029] According to an embodiment of the present invention, a gas-liquid mixing device based on dynamic dissolution is provided, comprising:

[0030] The liquid circuit unit 5 includes a liquid circuit tank, and a turbulence structure is provided in the liquid circuit tank. The turbulence structure is used to make the liquid in the liquid circuit tank flow in a vortex shape.

[0031] Gas passage unit 1 is disposed on the open end face side of the liquid passage tank, and a venting surface is provided corresponding to the open end face of the liquid passage tank.

[0032] A gas-liquid isolation membrane 4 is laid between the liquid circuit unit 5 and the gas circuit unit 1. The gas-liquid isolation membrane 4 is used to seal and cover the open end face of the liquid circuit tank.

[0033] The filter structure 2 is laid between the gas passage unit 1 and the gas-liquid isolation membrane 4. The gas in the gas passage unit 1 is suitable to enter the liquid passage tank by passing through the air passage surface, the filter structure 2, the gas-liquid isolation membrane 4 and the open end face in sequence.

[0034] The gas-liquid mixing device based on dynamic dissolution provided in this embodiment extends the liquid flow path through the liquid channel tank, and works with the gas-liquid isolation membrane 4 to increase the area and time of gas-liquid contact. By setting up a turbulence structure to create eddies in the liquid, the liquid contacts the gas-liquid isolation membrane 4 layer by layer during the flow, and the bubbles that have penetrated into the gas-liquid isolation membrane 4 near the liquid channel unit 5 are dynamically dissolved layer by layer, thereby greatly improving the efficiency of gas-liquid mixing.

[0035] Specifically, the liquid channel unit 5 also includes a substrate with a liquid channel groove having a complete long liquid channel path formed on the substrate. An open end face is formed on one side of the liquid channel groove along its length direction on the substrate. One end of the long path along the liquid channel groove is designated as the liquid channel inlet, and the other end as the liquid channel outlet. The liquid channel groove provides a strip-shaped liquid channel. As a channel for gas-liquid mixing, the liquid channel groove, in conjunction with the membrane structure of the gas-liquid isolation membrane 4, can increase the surface area of ​​the gas-liquid mixing passage and the gas-liquid contact range, thereby increasing the spatial volume and overall cycle of dynamic dissolution of gas-liquid mixed bubbles. The liquid channel groove is formed on the substrate in the form of an S-shape, U-shape, or planar spiral.

[0036] The turbulence structure is used to create a vortex-like flow of liquid in the liquid channel tank. Specific structures can refer to conventional turbulence plates or turbulence columns in existing technologies to prevent the liquid in the tank from flowing stably in a laminar state. For example... Figure 2 As shown, the side of the gas-liquid isolation membrane 4 facing the liquid channel tank is defined as the inner side 7 of the gas-liquid isolation membrane. After the gas in the gas channel unit 1 permeates through the gas-liquid isolation membrane 4 to one side of the liquid channel unit 5, several air bubbles will adhere to the inner side 7 of the gas-liquid isolation membrane. The vortex-flowing liquid in the liquid channel tank will wash away these air bubbles from the inner side 7 of the gas-liquid isolation membrane. Specifically, the microfluidic shear force of the vortex-flowing liquid in the liquid channel unit 5 is defined as F. J With the air path F Q and liquid path F Y Nonlinear F generated by different transformations J This process removes air bubbles adhering to the inner surface 7 of the gas-liquid separation membrane. Each layer of air bubbles that permeates is washed away. These air bubbles are located at F... JUnder continuous action, it will gradually and dynamically dissolve in the liquid in the liquid channel.

[0037] Air circuit unit 1 can be as follows Figure 1 The diagram shows a cavity-type structure covering the open end face of the liquid channel tank; it can also be a pipe-type structure arranged along the path of the liquid channel tank. The gas channel unit 1 has a venting surface corresponding to its open end face, allowing gas from the gas channel unit 1 to enter the liquid channel tank through the venting surface and the open end face. The edge of the gas channel unit 1 is sealed and fixedly connected to the edge of the substrate to prevent gas leakage at the gap between the gas channel unit 1 and the liquid channel unit 5. The inlet end of the gas channel unit 1 is equipped with a gas pipe connector for connecting an inlet pipe. Flow meters are respectively installed on the gas channel unit 1 and the liquid channel unit 5 to detect gas flow rate and liquid flow rate, respectively.

[0038] The filter structure 2 is used to trap impurities in the gas, preventing impurities from contaminating the liquid and affecting the permeability of the gas-liquid separation membrane 4.

[0039] The gas-liquid isolation membrane 4 is used to prevent liquid from entering the gas passage unit 1 from the liquid passage unit 5, while allowing gas from the gas passage unit 1 to enter the liquid passage unit 5. The gas-liquid isolation membrane 4 is laid flat on the liquid passage tank and covers the open end face of the liquid passage tank. As a feasible embodiment, the gas passage unit 1 is disposed above the liquid passage unit 5. After the gas permeates to the area below the gas-liquid isolation membrane 4, it forms bubbles. These bubbles adhere to the lower surface of the gas-liquid isolation membrane 4. The liquid in the liquid passage tank flows in a vortex shape and continuously carries away the attached bubbles to achieve gas-liquid mixing.

[0040] In one embodiment, the filter structure 2 includes a micro-nano filter with multiple pores.

[0041] Specifically, as a feasible implementation, the filter structure 2 is selected as a micro / nano-scale filter, which is made of stainless steel and has an inner diameter of pores less than or equal to 80 μm. The pore area accounts for at least 60% of the micro / nano-scale filter area to avoid excessive gas resistance. As an additional implementation, the filter structure 2 is selected as a millimeter-scale filter, which has multiple pores of 1 mm to 5 mm. Compared to the micro / nano-scale filter, the millimeter-scale filter has lower filtration accuracy but lower gas resistance. In an embodiment not shown, the gas-liquid mixing device based on dynamic dissolution also includes a filter plate, which is disposed on the side of the filter structure 2 away from the liquid path unit 5. Gas is adapted to pass through the filter plate and the filter structure 2 sequentially before entering the liquid path unit 5. The size of the filter pores on the filter plate is larger than the size of the pores in the filter structure 2. The filter plate is used for preliminary filtration of larger impurities.

[0042] Furthermore, the filter structure 2 abuts against the side of the gas-liquid isolation membrane 4 opposite to the liquid path unit 5. The sieve holes divide the gas in the gas path unit 1 into micro-nano-level airflows, facilitating the formation of micro-nano-level bubbles on the inner surface 7 of the gas-liquid isolation membrane, which is beneficial for improving gas-liquid mixing efficiency. Moreover, when the gas-liquid mixing device is large, such as the size of an A3 or A4 sheet of paper, the gas-liquid isolation membrane 4 is very thin and easily deformed under pressure. Therefore, the filter structure 2 is fixedly installed between the gas-liquid isolation membrane 4 and the gas path unit 1 to abut and support the gas-liquid isolation membrane 4, reducing the deformation caused by gas-liquid pressure and liquid eddy current impact, minimizing wrinkles in the gas-liquid isolation membrane 4, and preventing excessive deformation or rupture. The liquid path groove is a long path groove with a small width at its opening end face. The substrate structure surface around the opening end face can be used to support the side of the gas-liquid isolation membrane 4 opposite to the filter structure 2.

[0043] In one embodiment, combined Figure 1 As shown, a sealing unit 3 is provided between the gas path unit 1 and the gas-liquid isolation membrane 4. The filter structure 2 is located inside the sealing unit 3 and abuts against the inner side of the sealing unit 3.

[0044] The gas-liquid mixing device based on dynamic dissolution provided in this embodiment uses a sealing unit 3 to improve the sealing effect at the edge of the gas path unit 1 and the gas-liquid isolation membrane 4, so as to prevent gas leakage at that point.

[0045] Specifically, the sealing unit 3 is a rubber or silicone gasket, the shape and size of which are adapted to the edges of the gas passage unit 1 and the gas-liquid isolation membrane 4. The opposite sides of the sealing unit 3 are respectively fitted to the adjacent sides of the gas-liquid isolation membrane 4 and the gas passage unit 1, used to seal the gaps between the edges of the gas passage unit 1 and the gas-liquid isolation membrane 4. The liquid passage unit 5 and the gas passage unit 1 clamp and fix the gas-liquid isolation membrane 4 and the sealing unit 3. The sealing unit 3 has a through hole corresponding to the air passage surface of the gas passage unit 1, and the filter structure 2 is disposed inside the through hole and abuts against the inner wall of the through hole.

[0046] In one embodiment, the liquid circuit unit 5 is made of a rigid metal material, and the gas circuit unit 1 is made of a flexible non-metallic material.

[0047] The gas-liquid mixing device based on dynamic dissolution provided in this embodiment utilizes the flexible deformation of the gas path unit 1 to match the stable structure of the liquid path unit 5, so as to improve the sealing effect between the two.

[0048] Specifically, the liquid circuit unit 5 is made of a metal with high rigidity, while the gas circuit unit 1 is made of a non-metal with a certain degree of elasticity. The edge of the gas circuit unit 1 is sealed and abutted against the gas-liquid isolation membrane 4 on the substrate through the sealing unit 3. The flexible deformation of the gas circuit unit 1 and the gas-liquid isolation membrane 4 compensates for errors during the assembly process, thereby improving the sealing effect between the gas circuit unit 1 and the liquid circuit unit 5.

[0049] In one embodiment, the gas circuit unit 1 is provided with a pressure relief valve, which is used to release pressure when the gas pressure in the gas circuit unit 1 exceeds a preset value.

[0050] Specifically, a pressure relief valve is installed to prevent the gas pressure in gas circuit unit 1 from exceeding a preset value. When gas is injected too quickly or the pressure is too high, the pressure relief valve is used to regulate the gas circuit and prevent the gas pressure in gas circuit unit 1 from exceeding the preset value. Furthermore, a silencer is installed at the outlet of the pressure relief valve to reduce the noise generated during the pressure relief process.

[0051] In one embodiment, the gas-liquid mixing device based on dynamic dissolution further includes a gas pressure detector and a liquid pressure detector, wherein the gas pressure detector is used to detect the gas pressure of the gas circuit unit 1 and the liquid pressure detector is used to detect the liquid pressure of the liquid circuit unit 5.

[0052] Specifically, gas pressure detectors and liquid pressure detectors are installed to monitor the pressure in gas circuit unit 1 and liquid circuit unit 5 in real time. The gas pressure in gas circuit unit 1 and the liquid pressure in liquid circuit unit 5 can be adjusted according to actual needs to accommodate the mixing and reaction of different liquids and gases.

[0053] In one embodiment, combined Figure 2 As shown, the gas pressure in gas circuit unit 1 is defined as Fq, and the liquid pressure in liquid circuit unit 5 is defined as Fy, where Fq > Fy.

[0054] Specifically, by making Fq > Fy, it is beneficial to accelerate the gas permeation of the gas-liquid isolation membrane 4, increase the speed at which gas enters the liquid circuit unit 5, and ensure the continuous gas-liquid mixing.

[0055] In one embodiment, combined Figure 1 As shown, the gas-liquid mixing device based on dynamic dissolution also includes a heating unit 6 for heating the liquid in the liquid channel tank.

[0056] The gas-liquid mixing device based on dynamic dissolution provided in this embodiment improves the gas-liquid mixing and reaction efficiency by setting a heating unit 6 to heat the liquid in the liquid channel tank.

[0057] Specifically, the heating unit 6 is disposed within the liquid channel tank to directly heat the liquid, which not only accelerates the dynamic dissolution process of gas-liquid mixing but also improves the reaction effect required for gas-liquid mixing. A clearance groove can be provided on the wall of the liquid channel tank to house the heating unit 6; alternatively, the heating unit 6 can be directly disposed within the liquid channel, with its position avoiding turbulent structures.

[0058] In one embodiment, a temperature sensor is also provided in the liquid channel tank. The temperature sensor is used to detect the liquid temperature in the liquid channel tank and is electrically connected to the heating unit 6 through a temperature controller.

[0059] Specifically, multiple temperature sensors are evenly distributed at equal intervals along the length of the liquid path tank. A temperature controller is electrically connected to both the temperature sensors and the heating unit 6. The temperature controller has a preset temperature threshold range. It receives temperature signals from the temperature sensors to obtain the temperature of the liquid in the tank. The temperature controller compares the liquid temperature with the preset threshold range. When the temperature exceeds the preset range, it controls the heating unit 6 to stop heating; when the temperature is below the preset range, it controls the heating unit 6 to heat, thus controlling the liquid temperature within the preset range to meet the temperature requirements of different gas-liquid mixing reactions. The temperature controller is located outside the liquid path unit 5 and is powered by an external power supply or battery. The heating unit 6 includes a heating tube and an electric heating wire inserted inside the heating tube. The heating tube is filled with a liquid heat-conducting medium, such as water or heat-conducting oil. The electric heating wire converts electrical energy into heat energy to heat the liquid heat-conducting medium, thereby heating the liquid in the long-path liquid tank.

[0060] Furthermore, a heating unit and a temperature sensor are also provided in the gas circuit unit 1. The heating unit in the gas circuit unit 1 is electrically connected to the temperature sensor through a temperature controller so as to preheat the gas in the gas circuit unit 1 as needed.

[0061] According to an embodiment of the present invention, another aspect provides a gas-liquid mixing method based on dynamic dissolution, employing the aforementioned gas-liquid mixing device based on dynamic dissolution, comprising: introducing liquid into a liquid channel tank and maintaining it at a preset liquid pressure; introducing the required gas into a gas channel unit 1 and maintaining it at a preset gas pressure; filtering the gas through a filter structure 2; a pressure relief valve is provided on the gas channel unit 1, and the gas pressure in the gas channel unit 1 is adjusted by the pressure relief valve; so that the gas pressure is greater than the liquid pressure; after the gas permeates into the gas-liquid isolation membrane 4, a number of bubbles will adhere to the side of the gas-liquid isolation membrane 4 near the liquid channel tank; by providing a turbulence structure in the liquid channel tank to make the liquid flow in a vortex shape, the bubbles are dynamically dissolved into the liquid layer by layer.

[0062] Specifically, the gas path unit 1 is made of a non-metallic material with a certain degree of elasticity, while the liquid path unit 5 is made of a rigid metallic material. The flexible deformation of the non-metallic material is used to complement the stable structure of the metallic material, facilitating a better sealing effect in conjunction with the sealing unit 3. A heating unit 6 is installed inside the liquid path tank, heating the liquid according to the temperature required for mixing and reacting different gases and liquids. This not only accelerates the dynamic dissolution process of gas-liquid mixing but also improves the reaction effect required for gas-liquid mixing. The vortex-like flow of liquid continuously washes away the air bubbles attached to the inner surface 7 of the gas-liquid isolation membrane. Each layer that penetrates is washed away, thus achieving layer-by-layer dynamic dissolution of the gas, facilitating simultaneous mixing and reaction of gas and liquid within the liquid path tank.

[0063] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
