Description

Technical Field

[0001] This utility model belongs to the field of chemical production technology, and in particular relates to a gas-liquid reaction device with microbubble preparation function. Background Technology

[0002] Gas-liquid reaction equipment is a specialized device used in chemical processes to achieve mass transfer and reaction between gases and liquids. It is widely used in processes such as absorption, oxidation, hydrogenation, chlorination, and fermentation. Currently, commonly used gas-liquid reaction equipment includes stirred tank reactors, bubble column reactors, packed towers, and plate towers. These devices significantly improve the efficiency of the mass transfer process by optimizing the morphology of the gas-liquid two-phase contact interface and the fluid dynamics characteristics.

[0003] In existing technologies, some gas-liquid reaction devices incorporate ultrasonic enhancement technology. This technology uses an ultrasonic transducer to emit ultrasonic waves, which, when propagating in the liquid, induce cavitation, generating numerous micron-sized bubbles. These microbubbles possess a large specific surface area, a fast reaction rate, and a low rise velocity, significantly improving the efficiency of the gas-liquid reaction. However, existing ultrasonic-enhanced gas-liquid reaction devices typically only employ a single ultrasonic transducer, leading to complex interference effects, the formation of standing wave fields unfavorable for energy transfer, or multipath reflection within a limited space. These adverse factors not only deplete the energy of the ultrasonic waves but also affect the generation density, trajectory, and spatial distribution uniformity of the microbubbles, thus limiting the overall efficiency of the gas-liquid reaction and restricting the practical application of ultrasonic enhancement technology.

[0004] Therefore, there is an urgent need for a gas-liquid reaction device with microbubble preparation function to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a gas-liquid reaction device with microbubble preparation function, which can avoid the occurrence of ultrasonic interference effect, standing wave field generation and multipath reflection phenomenon, reduce ultrasonic energy loss and ensure the efficiency of gas-liquid reaction.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A gas-liquid reaction device with microbubble preparation function is provided, comprising:

[0008] The reaction element is provided with a reaction chamber.

[0009] An ultrasonic transmitting assembly is disposed within a reaction chamber. The ultrasonic transmitting assembly includes multiple ultrasonic transducers and several ultrasonic absorbers. The multiple ultrasonic transducers are spaced apart in a vertical direction, and an ultrasonic absorber is disposed between any two adjacent ultrasonic transducers. A serpentine reaction channel is formed between the multiple ultrasonic transducers, through which liquids and gases can pass. The ultrasonic transducers are configured to emit ultrasonic waves, and the ultrasonic absorbers are configured to absorb reflected ultrasonic waves.

[0010] Optionally, the ultrasonic transducer is provided with a first perforation, and the ultrasonic absorber is provided with a second perforation. The first perforation of the ultrasonic transducer and the second perforation of the adjacent ultrasonic absorber are arranged in a horizontally staggered manner.

[0011] Optionally, the ultrasonic energy absorber includes a metal support and an energy-absorbing layer encased in the metal support, the energy-absorbing layer being configured to absorb reflected ultrasonic waves.

[0012] Optionally, the ultrasonic energy-absorbing component may also include an elastic adhesive layer, which is disposed between the metal support and the energy-absorbing layer and is bonded to both the metal support and the energy-absorbing layer.

[0013] Optionally, the ultrasonic transducer includes a main body and a plurality of transducers disposed on the main body, the plurality of transducers being arranged in a matrix, and the transducers being configured to convert electrical signals into mechanical vibrations to generate ultrasonic waves.

[0014] Optionally, the gas-liquid reaction device with microbubble preparation function also includes a support, which is set inside the reaction chamber and detachably connected to the reaction components, and the ultrasonic emission component can be installed on the support.

[0015] Optionally, the gas-liquid reaction device with microbubble preparation function also includes a circulation component disposed on the reaction vessel. The circulation component is provided with a circulation channel communicating with the reaction chamber. The circulation component is used to provide circulation power for the liquid entering the circulation channel, so that the liquid flowing out from the serpentine reaction channel can flow into the circulation channel and flow back into the reaction chamber under the action of the circulation power of the circulation component.

[0016] Optionally, the reaction element is provided with an air inlet, and the circulation component includes a first connecting pipe and a circulation pump disposed on the first connecting pipe. Both ends of the first connecting pipe are connected to the reaction chamber, and the liquid inlet of the first connecting pipe is located above the ultrasonic emitting component, while the air inlet and the liquid outlet of the first connecting pipe are located below the ultrasonic emitting component. The circulation pump is used to provide circulation power for the liquid in the circulation channel.

[0017] Optionally, the gas-liquid reaction equipment with microbubble preparation function also includes an exhaust gas treatment component, which is located on top of the reaction vessel and is used to recover and treat unreacted gases in the reaction chamber.

[0018] Optionally, the gas-liquid reaction device with microbubble preparation function also includes an ultrasonic controller, which is located on the reaction element and electrically connected to the ultrasonic emission component to control the opening and closing of the ultrasonic emission component.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention provides a gas-liquid reaction device with microbubble preparation function. Gas in the reaction chamber enters the serpentine reaction channel of the ultrasonic transmitting component along with the liquid. Ultrasonic waves generated by the ultrasonic transducer cause cavitation in the gas entering the serpentine reaction channel, transforming it from a large-volume bubble into multiple microbubbles. Compared to large-volume bubbles, microbubbles have a smaller surface area and a slower rising speed, allowing for more thorough contact with the liquid in the serpentine reaction channel, thus significantly accelerating the gas-liquid reaction and improving its efficiency. Furthermore, the cavitation effect generates instantaneous high temperature and driving force. This high temperature helps to increase the gas-liquid reaction rate, further improving the efficiency of the gas-liquid reaction; the driving force pushes the microbubbles further away to avoid aggregation and ensure the contact area between the liquid and the microbubbles. In addition, the long extension of the serpentine reaction channel not only increases the number of microbubbles generated but also increases the contact time between the gas and liquid within the ultrasonic transmitting component, further improving the efficiency and effect of the gas-liquid reaction. The ultrasonic waves generated by the ultrasonic transducers will propagate and reflect between two adjacent ultrasonic transducers. The reflected waves generated by the reflection can be absorbed by the ultrasonic energy absorber between the two ultrasonic transducers, which can significantly reduce the number of ultrasonic wave reflections and the energy loss of reflection. This will disrupt the conditions for the formation of the standing wave field and reduce the interference between multiple ultrasonic waves, significantly simplifying the propagation path of the ultrasonic waves. It will also help concentrate energy into the serpentine reaction channel, so as to ensure the uniformity of the number, trajectory and distribution of microbubbles at various positions in the serpentine reaction channel, and improve the overall efficiency of the gas-liquid reaction.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1

[0038] like Figures 1 to 6 As shown, this embodiment provides a gas-liquid reaction device with microbubble preparation function, which can avoid the occurrence of ultrasonic interference effect, standing wave field generation and multipath reflection phenomenon, reduce ultrasonic energy loss and ensure the efficiency of gas-liquid reaction.

[0039] See Figure 1 and Figure 2 The gas-liquid reaction device with microbubble preparation function includes a reaction element 1 and an ultrasonic emitting component 2. The reaction element 1 is provided with a reaction chamber 11. The ultrasonic emitting component 2 is disposed in the reaction chamber 11. The ultrasonic emitting component 2 includes multiple ultrasonic transducers 21 and several ultrasonic absorbers 22. The multiple ultrasonic transducers 21 are arranged at intervals in the vertical direction. An ultrasonic absorber 22 is provided between any two adjacent ultrasonic transducers 21. A serpentine reaction channel is formed between the multiple ultrasonic transducers 21. Liquid and gas can pass through the serpentine reaction channel. The ultrasonic transducers 21 are configured to emit ultrasonic waves, and the ultrasonic absorbers 22 are configured to absorb reflected ultrasonic waves.

[0040] The gas-liquid reaction apparatus with microbubble preparation function provided in this embodiment allows gas in the reaction chamber 11 to enter the serpentine reaction channel of the ultrasonic transmitting component 2 along with the liquid. The ultrasonic waves generated by the ultrasonic transducer 21 cause cavitation of the gas entering the serpentine reaction channel, transforming it from a large-volume bubble into multiple microbubbles. Compared to large-volume bubbles, microbubbles have a smaller specific surface area and a slower rising speed, allowing for sufficient contact with the liquid in the serpentine reaction channel, thus significantly accelerating the gas-liquid reaction speed and improving its efficiency. Furthermore, the cavitation effect generates instantaneous high temperature and driving force. This high temperature helps to increase the gas-liquid reaction speed, further improving the efficiency of the gas-liquid reaction; the driving force pushes the microbubbles further away to avoid bubble aggregation and ensure the contact area between the liquid and the microbubbles. In addition, the long extension of the serpentine reaction channel not only increases the number of microbubbles generated but also increases the contact time between the gas and liquid in the ultrasonic transmitting component 2, thereby further improving the efficiency and effect of the gas-liquid reaction. The ultrasonic waves generated by the ultrasonic transducer 21 will propagate and reflect between two adjacent ultrasonic transducers 21. The reflected waves generated by the reflection can be absorbed by the ultrasonic energy absorber 22 between the two ultrasonic transducers 21, which can significantly reduce the number of ultrasonic wave reflections and the energy loss of reflection. This will disrupt the conditions for the formation of the standing wave field and reduce the interference between multiple ultrasonic waves, significantly simplify the propagation path of the ultrasonic waves, and help concentrate energy into the serpentine reaction channel to ensure the uniformity of the number, trajectory and distribution of microbubbles at each position in the serpentine reaction channel, thereby improving the overall efficiency of the gas-liquid reaction.

[0041] Specifically, the ultrasonic energy absorber 22 can reduce the loss of ultrasonic energy, so that the utilization rate of ultrasonic waves in the ultrasonic transmitting assembly 2 can reach more than 60%.

[0042] For example, see Figure 2 The ultrasonic transmitting component 2 includes three ultrasonic transducers 21 and two ultrasonic absorbers 22.

[0043] Optionally, see Figure 2The ultrasonic transducer 21 has a first perforation 211, and the ultrasonic absorber 22 has a second perforation 221. The first perforation 211 of the ultrasonic transducer 21 and the second perforation 221 of the adjacent ultrasonic absorber 22 are staggered in the horizontal direction. This arrangement allows liquid to flow from one side of the ultrasonic transducer 21 to the other side through the first perforation 211, and from one side of the ultrasonic absorber 22 to the other side through the second perforation 221. The flow directions of the liquid on the upper and lower sides of each ultrasonic transducer 21 and each ultrasonic absorber 22 are opposite. That is, the serpentine reaction channel is composed of the first perforation 211 of multiple ultrasonic transducers 21, the second perforation 221 of several ultrasonic absorbers 22, and the space between each ultrasonic transducer 21 and its adjacent ultrasonic absorber 22, thereby realizing the serpentine flow of liquid in the ultrasonic emitting assembly 2, fully increasing the contact time between gas and liquid in the ultrasonic emitting assembly 2, and improving the efficiency and effect of gas-liquid reaction.

[0044] See Figure 2 In the orientation of the ultrasonic transducer 21, the first perforation 211 is located at the right end of the ultrasonic transducer 21, and the second perforation 221 is located at the left end of the ultrasonic absorber 22. This arrangement allows the extension length of the serpentine reaction channel to be maximized.

[0045] For example, see Figure 1 , Figure 3 and Figure 5 The reaction chamber 11 has a circular cross-sectional shape. Both the ultrasonic transducer 21 and the ultrasonic absorber 22 adopt a disk structure. The first perforation 211 extends along the thickness direction of the ultrasonic transducer 21, and the second perforation 221 extends along the thickness direction of the ultrasonic absorber 22.

[0046] Optionally, see Figure 6 The ultrasonic energy absorber 22 includes a metal support 222 and an energy-absorbing layer 223 encased in the metal support 222. The energy-absorbing layer 223 is configured to absorb reflected ultrasonic waves. The metal support 222 serves as the foundation structure of the entire ultrasonic energy absorber 22, providing stable support for the energy-absorbing layer 223 and ensuring the structural integrity of the ultrasonic energy absorber 22 under ultrasonic waves or other external forces, preventing deformation or damage. Furthermore, metal has good thermal conductivity; during energy absorption, the ultrasonic energy absorber 22 may generate heat, which the metal support 222 can promptly conduct away, preventing localized overheating from affecting the performance of the ultrasonic energy absorber 22 and ensuring its normal operation. The energy-absorbing layer 223 absorbs reflected ultrasonic waves, thereby reducing ultrasonic wave reflection and propagation, achieving the purpose of disrupting the formation conditions of standing wave fields and interference effects.

[0047] For example, the metal support 222 is made of a metal plate, and the energy-absorbing layer 223 is made of flexible foam. The flexible foam has a large number of micropores inside, which can effectively absorb ultrasonic energy and convert it into other forms of energy such as heat energy, thereby reducing the reflection and propagation of ultrasonic waves and achieving the purpose of absorbing ultrasonic waves. In addition, the energy-absorbing layer 223 made of flexible foam has good flexibility. When the ultrasonic energy-absorbing component 22 is subjected to external impact, the energy-absorbing layer 223 can absorb and disperse the impact energy through its own deformation, playing a role in buffering and shock absorption, and protecting the metal support 222 from damage.

[0048] In this embodiment, see Figure 6 The ultrasonic energy absorber 22 also includes an elastic adhesive layer 224, which is disposed between the metal support 222 and the energy absorber 223, and is bonded to both the metal support 222 and the energy absorber 223. The elastic adhesive layer 224 can firmly bond the metal support 222 and the energy absorber 223 together, ensuring that the layers of the ultrasonic energy absorber 22 will not separate during long-term use; moreover, the elastic adhesive layer 224 has a certain degree of elasticity, which can absorb some energy when the ultrasonic energy absorber 22 is subjected to impact or vibration, playing a certain buffering role and reducing the impact force on the metal support 222.

[0049] For example, the elastic adhesive layer 224 is a rigid microbubble adhesive layer. The microbubble structure inside the rigid microbubble adhesive layer can buffer the stress during the bonding process to a certain extent, improving the reliability and durability of the bonding; the special structure of the rigid microbubble adhesive layer can also have a certain influence on the propagation of ultrasonic waves, such as changing the reflection, refraction and absorption characteristics of ultrasonic waves, which helps to optimize the acoustic performance of the ultrasonic energy absorber 22 and improve its absorption effect of ultrasonic energy.

[0050] Optionally, see Figure 3 and Figure 4 The ultrasonic transducer 21 includes a main body 212 and multiple transducers 213 disposed on the main body 212. The multiple transducers 213 are arranged in a matrix. The transducers 213 are configured to convert electrical signals into mechanical vibrations to generate ultrasonic waves, thereby achieving the purpose of generating ultrasonic waves by the ultrasonic transducer 21. The matrix arrangement of the multiple transducers 213 not only ensures that the generated ultrasonic energy can uniformly cover the serpentine reaction channel, avoiding uneven distribution of microbubbles caused by excessively high or low local energy, which would affect the gas-liquid reaction effect, but also reduces mutual interference between the transducers 213 and enhances the directionality and focusing of the generated ultrasonic waves, thereby improving the cavitation effect on the gas.

[0051] For example, the transducer 213 employs a transducer head. The electrical oscillation signal from the excitation power supply causes a change in the electric or magnetic field of the energy storage element in the transducer head. This change, through the piezoelectric effect, generates a driving force on the mechanical vibration system of the transducer head, causing it to enter a vibration state. This, in turn, causes the medium in contact with the mechanical vibration system of the transducer head to vibrate, radiating ultrasonic waves into the medium. Specifically, the frequency of the ultrasonic transducer 21 is in the range of 20kHz to 80kHz, and the power density is 0.8W / cm². 2 ~2.0W / cm 2 Within the range.

[0052] Optionally, see Figure 1 and Figure 2 The gas-liquid reaction device with microbubble preparation function also includes a support 3, which is disposed within the reaction chamber 11 and detachably connected to the reaction component 1. The ultrasonic emitting component 2 can be installed on the support 3. This arrangement allows the support 3 to connect or disconnect the ultrasonic emitting component 2 from the reaction component 1, facilitating quick installation or removal of the ultrasonic emitting component 2 from the reaction chamber 11 by operators, thus improving the convenience of maintenance and replacement of the ultrasonic emitting component 2.

[0053] For example, the support 3 is detachably connected to the reaction chamber 11 by bolts.

[0054] Specifically, the support 3 includes an annular frame and multiple protrusions disposed on the annular frame. The multiple protrusions are arranged at intervals in the vertical direction and extend circumferentially along the annular frame. The ultrasonic transducer 21 or ultrasonic absorber 22 can be embedded between two adjacent protrusions and is circumferentially limited by the annular frame to complete the stable installation of the ultrasonic transmitting component 2 on the support 3.

[0055] Optionally, see Figure 1 and Figure 2 The gas-liquid reaction device with microbubble preparation function also includes an ultrasonic controller 61. The ultrasonic controller 61 is disposed on the reaction element 1 and electrically connected to the ultrasonic emitting component 2, and is used to control the opening and closing of the ultrasonic emitting component 2. This configuration can improve the automation level of the gas-liquid reaction device with microbubble preparation function and facilitate operation by staff.

[0056] In this embodiment, the ultrasonic controller 61 and the ultrasonic transmitting component 2 are connected by a wire 611. A protective tube is fitted on the wire 611 to prevent the liquid in the reaction chamber 11 from damaging the wire 611.

[0057] Optionally, see Figure 1The reaction chamber 1 includes a reaction cylinder 12, a first cover 13, and a second cover 14. The first cover 13 is detachably disposed at the upper end of the reaction cylinder 12 to seal the upper opening of the reaction cylinder 12. The second cover 14 is detachably disposed at the lower end of the reaction cylinder 12 to seal the lower opening of the reaction cylinder 12. The reaction cylinder 12, the first cover 13, and the second cover 14 form a reaction chamber 11. The ultrasonic emitting component 2 is located inside the reaction cylinder 12. The first cover 13 is provided with a feeding port 131, through which liquid is fed into the reaction chamber 11. The second cover 14 is provided with an air inlet, through which gas enters the reaction chamber 11. This arrangement allows the reaction chamber 11 to form a state where liquid enters from the upper end and gas enters from the lower end. Under the action of gravity, the liquid flows downward and the gas moves upward, forming a countercurrent contact. This countercurrent contact method allows for longer contact time and a larger contact area between the gas and liquid phases, enhancing the mass transfer process between the gas and liquid and improving the gas-liquid mixing effect.

[0058] Specifically, see Figure 1 The ultrasonic controller 61 is located outside the reaction element 1, and the wire 611 between the ultrasonic controller 61 and the ultrasonic transmitting assembly 2 passes through the first cover 13.

[0059] For example, flanges are provided between the first cover 13 and the reaction cylinder 12, and between the second cover 14 and the reaction cylinder 12, to ensure the sealing of the connection.

[0060] In this embodiment, see Figure 1 The gas-liquid reaction device with microbubble preparation function also includes a gas explosion head 51 set at the gas inlet. The gas explosion head 51 is configured to send gas into the reaction chamber 11 in the form of bubbles to ensure the contact area between the gas and liquid phases and enhance the mixing effect of the gas and liquid phases.

[0061] Example 2

[0062] like Figure 1As shown, the gas-liquid reaction device with microbubble preparation function provided in this embodiment also includes a circulation component 4 disposed on the reaction element 1. The circulation component 4 is provided with a circulation channel communicating with the reaction chamber 11. The circulation component 4 is used to provide circulation power for the liquid entering the circulation channel, so that the liquid flowing out of the serpentine reaction channel can flow into the circulation channel and flow back into the reaction chamber 11 under the action of the circulation power of the circulation component 4. This arrangement allows the liquid to circulate in the circulation channel and the serpentine reaction channel, thereby achieving sufficient stirring between the liquid and the gas. Compared with the prior art, the gas-liquid reaction device with microbubble preparation function provided in this embodiment can achieve the stirring effect of gas and liquid two phases without the need for a separate stirring component. This not only effectively reduces the energy consumption of the gas-liquid reaction device and improves the efficiency of the gas-liquid reaction, but also makes it suitable for gas-liquid reactions in which the liquid contains solid particles or in situations where solids are precipitated during the reaction process.

[0063] Specifically, compared to using a stirring paddle, this embodiment can reduce energy consumption by 25% to 35% and increase reaction efficiency by 40% to 60%.

[0064] In this embodiment, see Figure 1 The reaction component 1 is equipped with an air inlet. The circulation assembly 4 includes a first connecting pipe 41 and a circulation pump 42 disposed on the first connecting pipe 41. Both ends of the first connecting pipe 41 are connected to the reaction chamber 11, and the liquid inlet of the first connecting pipe 41 is located above the ultrasonic emitting assembly 2, while the air inlet and the liquid outlet of the first connecting pipe 41 are located below the ultrasonic emitting assembly 2. The inner cavity of the first connecting pipe 41 forms a circulation channel, and the circulation pump 42 is used to provide circulation power for the liquid in the circulation channel. This arrangement allows the circulating liquid and the gas to be reacted to enter the serpentine reaction channel in the same direction (from bottom to top), ensuring that the residence time of the gas and liquid in the reaction chamber 11 is consistent and effectively preventing gas-liquid back-mixing.

[0065] See Figure 1 When the liquid level in the reaction chamber 11 is higher than the inlet end of the first connecting pipe 41, the liquid can overflow into the first connecting pipe 41. At this time, when the circulation pump 42 is turned on, the liquid in the first connecting pipe 41 can flow back into the reaction chamber 11 from the outlet end of the first connecting pipe 41 under the power of the circulation pump 42. The liquid flowing back into the reaction chamber 11 can come into contact with the bubbles generated by the gas explosion head 51 and enter the serpentine reaction channel together.

[0066] Specifically, see Figure 1The second cover 14 is provided with a liquid inlet 141, and the liquid outlet end of the first connecting pipe 41 is provided with a connecting valve 43. The first connecting pipe 41 is connected to the liquid inlet 141 through the connecting valve 43. The connecting valve 43 is used to control the opening and closing of the liquid inlet 141 so that the staff can control the liquid entering the reaction chamber 11 from the circulation channel.

[0067] For example, the connecting valve 43 is a three-way valve.

[0068] Example 3

[0069] like Figure 1 As shown, the gas-liquid reaction device with microbubble preparation function provided in this embodiment also includes a tail gas treatment component 5. The tail gas treatment component 5 is disposed on the top of the reaction element 1 and is used to recover and treat unreacted gas in the reaction chamber 11 to prevent unmixed gas from being emitted into the surrounding air, thereby reducing the degree of pollution to the surrounding environment. The gas in the reaction chamber 11 will automatically move upward under the action of buoyancy. The tail gas treatment component 5 is disposed on the top of the reaction element 1, which can improve the recovery rate of unreacted gas.

[0070] Optionally, see Figure 1 The exhaust gas treatment component 5 includes a second connecting pipe and a compressor 53 disposed on the second connecting pipe. Both ends of the second connecting pipe are connected to the reaction chamber 11, with the inlet end of the second connecting pipe located above the ultrasonic emitting component 2 and the outlet end located below the ultrasonic emitting component 2. The compressor 53 is configured to compress the gas passing through the second connecting pipe. The compressor 53 compresses the gas in the second connecting pipe, thereby increasing the pressure inside the second connecting pipe, allowing the gas in the second connecting pipe to automatically flow towards the outlet end of the second connecting pipe, so that the recovered gas can re-enter the reaction chamber 11. The inlet end of the second connecting pipe is located above the ultrasonic emitting component 2, allowing unreacted gas to automatically rise into the second connecting pipe under the action of buoyancy; the outlet end of the second connecting pipe is located below the ultrasonic emitting component 2, allowing the gas to re-enter the serpentine reaction channel after re-entering the reaction chamber 11 and undergo cavitation, realizing internal gas circulation, significantly improving gas utilization and reducing gas usage costs.

[0071] Specifically, this setup allows the gas utilization rate to be increased to over 80% to 95%.

[0072] Specifically, the outlet end of the second connecting pipe passes through the air inlet and connects to the air explosion head 51.

[0073] For example, the compressor 53 is a gas compression pump.

[0074] In this embodiment, the gas-liquid reaction device with microbubble preparation function also includes a gas supply component, which is connected to the second connecting pipe and used to supply gas to the second connecting pipe. This arrangement allows the gas supply component to supply gas to the second connecting pipe when the amount of recovered gas is insufficient to meet the reaction requirements, thereby ensuring the effectiveness of the gas-liquid reaction within the reaction chamber 11.

[0075] See Figure 1 The exhaust gas treatment assembly 5 also includes a pressure detection element 54 installed on the second connecting pipe, and a gas supply control element 62 installed on the gas supply component. The pressure detection element 54 and the gas supply control element 62 are electrically connected. The pressure detection element 54 is configured to detect the pressure inside the second connecting pipe, and the gas supply control element 62 is configured to control the opening and closing of the gas supply component based on the pressure detected by the pressure detection element 54. The inner cavity of the second connecting pipe and the reaction chamber 11 form an interconnected and enclosed space. Therefore, the pressure measured by the pressure detection element 54 is the pressure inside the reaction chamber 11. This allows operators to obtain information about the gas reaction status inside the reaction chamber 11 based on the pressure of the second connecting pipe, and adjust the gas supply in real time to ensure the normal progress of the gas-liquid reaction. Furthermore, the installation of the pressure detection element 54 and the gas supply control element 62 enables autonomous adjustment of the gas supply within the reaction chamber 11, reducing manual operation costs and ensuring the stability of the gas supply.

[0076] Specifically, when the pressure detection element 54 detects that the pressure inside the second connecting pipe is greater than the maximum pressure set for the gas-liquid reaction, it indicates that the gas supply from the second connecting pipe to the reaction chamber 11 is greater than the amount of gas reacting in the reaction chamber 11. At this time, the gas supply control element 62 controls the gas supply element to close, thereby reducing the gas supply from the second connecting pipe to the reaction chamber 11. When the pressure detection element 54 detects that the pressure inside the second connecting pipe is less than the minimum pressure set for the gas-liquid reaction, it indicates that the gas supply from the second connecting pipe to the reaction chamber 11 is less than the amount of gas reacting in the reaction chamber 11. At this time, the gas supply control element 62 controls the gas supply element to open, thereby supplying gas to the second connecting pipe and increasing the gas supply to the reaction chamber 11. The set maximum and minimum pressures are determined according to the specific reaction conditions.

[0077] Optionally, see Figure 1 The exhaust gas treatment component 5 includes a gas storage component 55 disposed on the reaction component 1. The gas storage component 55 is provided with a gas storage space that can communicate with the reaction chamber 11. The gas storage space is used to store unreacted gas in the reaction chamber 11 to realize the recovery and storage of gas, so as to facilitate the subsequent centralized treatment of the recovered gas by the staff.

[0078] Specifically, see Figure 1The second connecting pipe includes a first pipe section 521, a second pipe section 522, a third pipe section 523, and a fourth pipe section 524. The first pipe section 521 is connected to the first cap 13. One end of the second pipe section 522 is connected to the first pipe section 521, and the other end is connected to the compressor 53. One end of the third pipe section 523 is connected to the compressor 53, and the other end is connected to the gas storage unit 55. One end of the fourth pipe section 524 is connected to the gas storage unit 55, and the other end is connected to the second cap 14. A pressure detection element 54 is installed on the gas storage unit 55 to detect the pressure in the gas storage space. A gas supply element is connected to the gas storage unit 55 to supply gas to the gas storage space. Unreacted gas can enter the first pipe section 521 and then enter the compressor 53 via the second pipe section 522 for compression. The compressed gas can then enter the gas storage space of the gas storage unit 55 via the third pipe section 523. The gas in the gas storage space can then enter the reaction chamber 11 via the fourth pipe section 524.

[0079] See Figure 1 The second pipe section 522 is connected to the middle of the first pipe section 521. A first control valve 561 is installed at the end of the first pipe section 521 furthest from the first cover 13, controlling the opening and closing of that end of the first pipe section 521. A second control valve 562 is installed on the second pipe section 522, controlling its opening and closing. A third control valve 563 is installed on the fourth pipe section 524, controlling its opening and closing. During gas recovery processing, the first control valve 561 is closed, while the second and third control valves 562 and 563 are both open. When gas recovery is not required, the first control valve 561 can be opened and the second control valve 562 closed.

[0080] For example, the gas storage well is a tank.

[0081] In this embodiment, see Figure 1 The bottom of the gas storage unit 55 is equipped with a drain port and a fourth control valve 564 located at the drain port. The fourth control valve 564 is used to control the opening and closing of the drain port. The recovered gas carries water vapor. When a certain amount of gas is stored in the gas storage unit 55, the amount of water vapor carried into the gas storage unit 55 by the gas will also increase. The water vapor will occupy the volume of the gas, affecting the gas storage capacity of the gas storage unit 55. At this time, the fourth control valve 564 can be controlled to open the drain port to discharge the water vapor from the gas storage unit 55.

[0082] Optionally, see Figure 1 A demister 57 is provided on the top of the reaction unit 1. The exhaust gas treatment assembly 5 is connected to the demister 57. The demister 57 is used to remove water vapor from the gas so that the gas entering the exhaust gas treatment assembly 5 can be kept dry, which is convenient for subsequent gas treatment.

[0083] Specifically, see Figure 1 The demister 57 is installed on the first cover 13, and the first pipe section 521 is connected to the demister 57.

[0084] Example 4

[0085] like Figure 1 As shown, the gas-liquid reaction device with microbubble preparation function provided in this embodiment includes a reaction component 1, an ultrasonic emission component 2, a circulation component 4, an exhaust gas treatment component 5, and a control module 6. The control module 6 is electrically connected to the ultrasonic emission component 2, the circulation component 4, and the exhaust gas treatment component 5, and is used to control the working state of the ultrasonic emission component 2, the circulation component 4, and the exhaust gas treatment component 5, so as to improve the automation level of the gas-liquid reaction device with microbubble preparation function.

[0086] Specifically, see Figure 1 The control module 6 includes an ultrasonic controller 61 to control the opening and closing state of the ultrasonic transmitting component 2. The control module 6 is electrically connected to both the connecting valve 43 and the circulating pump 42 to control their opening and closing. The control module 6 includes a gas supply control component 62 to control the opening and closing of the gas supply component. The control module 6 is electrically connected to the first control valve 561, the second control valve 562, the third control valve 563, and the fourth control valve 564 to control their opening and closing.

[0087] For example, the first control valve 561, the second control valve 562, the third control valve 563 and the fourth control valve 564 are all electrically controlled valves.
