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. Background Technology

[0002] Gas-liquid reaction equipment, as key devices in chemical processes, is mainly used to realize mass transfer and chemical reactions between gases and liquids, and has wide applications in processes such as absorption, oxidation, hydrogenation, chlorination, and fermentation. Depending on different process requirements, commonly used industrial gas-liquid reaction equipment currently includes stirred tank reactors, bubble column reactors, packed towers, and plate towers. These devices significantly improve mass transfer efficiency through carefully designed gas-liquid two-phase contact interface morphology and optimized fluid dynamics characteristics.

[0003] Among them, stirred tank reactors occupy an important position in industrial production due to their structural characteristics. This equipment uses the rotational motion of a built-in agitator to force gas and liquid into a turbulent state within the reactor, thereby achieving sufficient gas-liquid contact and mixing. However, in practical applications, stirred tank reactors still have some technical limitations: First, when processing complex material systems containing large solid particles, conventional stirring devices often struggle to achieve completely uniform mixing, easily leading to localized uneven mixing; second, to achieve better mixing and mass transfer efficiency, the agitator power is usually high, which not only significantly increases energy costs but also raises the economic burden of equipment operation; furthermore, during long-term continuous operation, the agitator blades are subjected to continuous scouring and chemical corrosion from the material. This dual mechanical and chemical action leads to gradual wear of the agitator, resulting in a decrease in stirring efficiency, and in severe cases, even equipment failure, affecting production stability.

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

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a gas-liquid reaction device that improves the efficiency of gas-liquid reaction, reduces the energy consumption cost of gas-liquid reaction and the failure rate of gas-liquid reaction device, and can also be applied to gas-liquid reaction in liquid containing solid particles or in situations where solids are precipitated during the reaction process.

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

[0007] A gas-liquid reaction apparatus is provided, comprising:

[0008] The reaction body has a reaction chamber on it;

[0009] An ultrasonic transmitting component is disposed in the reaction body and located within the reaction chamber. The ultrasonic transmitting component is configured to generate ultrasonic waves to enable cavitation effect to occur within the reaction chamber.

[0010] A circulation component is installed on the reaction body. The circulation component has a circulation channel that communicates with the reaction chamber. The circulation component is used to provide circulation power for the liquid entering the circulation channel, so that the liquid in the reaction chamber can flow into the circulation channel and flow back into the reaction chamber under the power of the circulation component.

[0011] Optionally, the gas-liquid reaction device also includes an exhaust gas treatment component, which is located on top of the reaction body and is used to recover and treat unreacted gases in the reaction chamber.

[0012] Optionally, the exhaust gas treatment assembly includes a first connecting pipe and a compressor disposed on the first connecting pipe. Both ends of the first connecting pipe are connected to the reaction chamber, and the air inlet of the first connecting pipe is located above the ultrasonic emitting assembly, and the air outlet of the first connecting pipe is located below the ultrasonic emitting assembly. The compressor is configured to compress the gas passing through the first connecting pipe.

[0013] Optionally, the gas-liquid reaction device also includes a gas supply component, which is connected to the first connecting pipe and is used to supply gas to the first connecting pipe.

[0014] Optionally, the exhaust gas treatment assembly also includes a pressure detection element disposed on the first connecting pipe, and an air supply control element disposed on the air supply component. The pressure detection element is electrically connected to the air supply control element. The pressure detection element is configured to detect the pressure in the first connecting pipe, and the air supply control element is configured to control the opening and closing of the air supply component according to the pressure detected by the pressure detection element.

[0015] Optionally, the exhaust gas treatment component includes a gas storage device disposed on the reaction body, the gas storage device having a gas storage space that can communicate with the reaction chamber, the gas storage space being used to store unreacted gas in the reaction chamber.

[0016] Optionally, the bottom of the gas storage unit is provided with a drain port and a fourth control valve located at the drain port. The fourth control valve is used to control the opening and closing of the drain port.

[0017] Optionally, a demister is provided on the top of the reaction body, and the exhaust gas treatment assembly is connected to the demister. The demister is used to remove water vapor from the gas.

[0018] Optionally, the reaction body is provided with a vent, and the circulation component includes a second connecting pipe and a circulation pump disposed on the second connecting pipe. Both ends of the second connecting pipe are connected to the reaction chamber, and the liquid inlet of the second connecting pipe is located above the ultrasonic emitting component. The vent and the liquid outlet of the second connecting pipe are both located below the ultrasonic emitting component. The circulation pump is used to provide circulation power for the liquid entering the circulation channel.

[0019] Optionally, the ultrasonic transmitting assembly includes multiple ultrasonic transducers and several ultrasonic absorbers. The multiple ultrasonic transducers are arranged at intervals along the vertical direction, and an ultrasonic absorber is arranged 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.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention provides a gas-liquid reaction device. The ultrasonic waves generated by the ultrasonic transmitting component create a cavitation effect within the reaction chamber, breaking down large-volume bubbles into multiple microbubbles. Compared to large-volume bubbles, microbubbles have a larger specific surface area and a slower rising speed in the liquid, allowing for more thorough contact with the liquid, accelerating the gas-liquid reaction, and improving its efficiency. After ultrasonic treatment, the liquid in the reaction chamber enters a circulation channel. Under the power of the circulation component, the liquid re-enters the reaction chamber within the circulation channel, achieving a mixing effect between the liquid and gas, further enhancing the gas-liquid mixing effect. Compared to existing technologies, the gas-liquid reaction device provided by this invention achieves thorough gas-liquid mixing using only the ultrasonic transmitting and circulation components, improving mixing uniformity and eliminating the need for a separate stirrer. This not only reduces the energy consumption cost and failure rate of the gas-liquid reaction device but also makes it suitable for gas-liquid reactions involving solid particles in the liquid or situations where solids precipitate during the reaction, expanding the applicability of the gas-liquid reaction device.

[0035] It should be understood that in the description of this utility model, the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 6 As shown, this embodiment provides a gas-liquid reaction device that improves the efficiency of gas-liquid reaction, reduces the energy consumption cost of gas-liquid reaction and the failure rate of gas-liquid reaction device, and can also be applied to gas-liquid reactions in which the liquid contains solid particles or in situations where solids are precipitated during the reaction process.

[0039] See Figure 1 The gas-liquid reaction device includes a reaction body 1, an ultrasonic emitting component 2, and a circulation component 4. The reaction body 1 is provided with a reaction chamber 11. The ultrasonic emitting component 2 is disposed in the reaction body 1 and located in the reaction chamber 11. The ultrasonic emitting component 2 is configured to generate ultrasonic waves so that cavitation effect can occur in the reaction chamber 11. The circulation component 4 is disposed in the reaction body 1 and 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 in the reaction chamber 11 can flow into the circulation channel and flow back into the reaction chamber 11 under the power of the circulation component 4.

[0040] The gas-liquid reaction apparatus provided in this embodiment utilizes ultrasonic waves generated by the ultrasonic transmitting component 2 to induce cavitation within the reaction chamber 11. This cavitation effect breaks down large-volume bubbles within the reaction chamber 11 into multiple microbubbles. Compared to large-volume bubbles, microbubbles have a larger specific surface area and a slower rising speed in the liquid, allowing for greater contact with the liquid and accelerating the gas-liquid reaction, thus improving its efficiency. After ultrasonic treatment, the liquid within the reaction chamber 11 enters the circulation channel. Under the power of the circulation component 4, the liquid re-enters the reaction chamber 11 within the circulation channel, enabling the liquid to circulate between the reaction chamber 11 and the circulation channel. This achieves a stirring effect between the liquid and gas, further enhancing the mixing effect between the gas and liquid. Compared with the prior art, the gas-liquid reaction device provided in this embodiment can fully mix gas and liquid by using the ultrasonic emission component 2 and the circulation component 4, which improves the uniformity of mixing and eliminates the need for a stirrer. This not only reduces the energy consumption cost of gas-liquid reaction and the failure rate of gas-liquid reaction device, but also makes it applicable to gas-liquid reactions in liquids containing solid particles or in situations where solids are precipitated during the reaction, thus expanding the applicability of gas-liquid reaction device.

[0041] Specifically, compared to using a stirring paddle, the gas-liquid reaction device provided in this embodiment can reduce energy consumption by 25% to 35% and increase reaction efficiency by 40% to 60%.

[0042] In this embodiment, see Figure 1The reaction body 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 a vent, 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.

[0043] 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.

[0044] In this embodiment, see Figure 1 The gas-liquid reaction device also includes a gas explosion head 51 located at the vent. 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.

[0045] Optionally, see Figure 1 The gas-liquid reaction apparatus also includes an exhaust gas treatment component 5, which is located at the top of the reaction body 1. This component is used to recover and treat unreacted gases within the reaction chamber 11, preventing unmixed gases from being released into the surrounding air and reducing environmental pollution. The gases within the reaction chamber 11 automatically rise due to buoyancy. The location of the exhaust gas treatment component 5 at the top of the reaction body 1 improves the recovery rate of unreacted gases.

[0046] In this embodiment, see Figure 1The exhaust gas treatment component 5 includes a first connecting pipe and a compressor 53 disposed on the first connecting pipe. Both ends of the first connecting pipe are connected to the reaction chamber 11, with the inlet end of the first 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 first connecting pipe. The compressor 53 compresses the gas in the first connecting pipe, thereby increasing the pressure inside the first connecting pipe, allowing the gas in the first connecting pipe to automatically flow towards the outlet end of the first connecting pipe, so that the recovered gas can re-enter the reaction chamber 11. The inlet end of the first connecting pipe is located above the ultrasonic emitting component 2, allowing unreacted gas to automatically rise into the first connecting pipe under the action of buoyancy; the outlet end of the first connecting pipe is located below the ultrasonic emitting component 2, allowing the gas to undergo cavitation again under the action of the ultrasonic emitting component 2 after re-entering the reaction chamber 11, realizing internal gas circulation, significantly improving gas utilization and reducing gas usage costs.

[0047] Specifically, the gas utilization rate of the gas-liquid reaction device provided in this embodiment can be increased to over 80% to 95%.

[0048] Specifically, the outlet end of the first connecting pipe passes through the vent and connects to the air explosion head 51.

[0049] For example, the compressor 53 is a gas compression pump.

[0050] See Figure 1 The gas-liquid reaction apparatus also includes a gas supply component connected to a first connecting pipe for supplying gas to the first connecting pipe. This configuration allows the gas supply component to supply gas to the first connecting pipe when the amount of recovered gas is insufficient to meet the reaction requirements, thus ensuring the effectiveness of the gas-liquid reaction.

[0051] Specifically, see Figure 1 The exhaust gas treatment assembly 5 also includes a pressure detection element 54 disposed on the first connecting pipe, and a gas supply control element 62 disposed 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 first connecting pipe, and the gas supply control element 62 is configured to control the opening and closing of the gas supply component according to the pressure detected by the pressure detection element 54. The inner cavity of the first connecting pipe and the reaction chamber 11 form an interconnected and closed space. Therefore, the pressure measured by the pressure detection element 54 is the pressure inside the reaction chamber 11. This allows the operator to obtain the gas reaction status inside the reaction chamber 11 based on the pressure of the first connecting pipe, so as to adjust the gas supply in real time and ensure the normal progress of the gas-liquid reaction. Moreover, the setting of the pressure detection element 54 and the gas supply control element 62 enables the autonomous adjustment of the gas supply in the reaction chamber 11, reduces manual operation costs, and ensures the stability of the gas supply.

[0052] When the pressure sensor 54 detects that the pressure inside the first connecting pipe is greater than the maximum pressure set for the gas-liquid reaction, it indicates that the gas supply from the first 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 unit 62 controls the gas supply device to close, thereby reducing the gas supply from the first connecting pipe to the reaction chamber 11. When the pressure sensor 54 detects that the pressure inside the first connecting pipe is less than the minimum pressure set for the gas-liquid reaction, it indicates that the gas supply from the first 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 unit 62 controls the gas supply device to open, thereby supplying gas to the first 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.

[0053] In this embodiment, see Figure 1 The exhaust gas treatment component 5 includes a gas storage component 55 disposed on the reaction body 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 of gas and facilitate the subsequent centralized treatment of the recovered gas by the staff.

[0054] See Figure 1 The gas storage component 55 is disposed on the first connecting pipe. Specifically, the first 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 component 55. One end of the fourth pipe section 524 is connected to the gas storage component 55, and the other end is connected to the second cap 14. A pressure detection component 54 is disposed on the gas storage component 55 to detect the pressure in the gas storage space. A gas supply component is connected to the gas storage component 55 to supply gas to the gas storage space. Unreacted gas can enter the first pipe section 521 and then enter the compressor 53 through the second pipe section 522 for compression. The compressed gas can enter the gas storage space of the gas storage unit 55 through the third pipe section 523. The gas in the gas storage space can enter the reaction chamber 11 through the fourth pipe section 524.

[0055] Further, see Figure 1The 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.

[0056] For example, the gas storage well is a tank.

[0057] 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.

[0058] In this embodiment, see Figure 1 A demister 57 is provided on the top of the reaction body 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.

[0059] 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.

[0060] Optionally, see Figure 1 The reaction body 1 is equipped with a vent. The circulation component 4 includes a second connecting pipe 41 and a circulation pump 42 disposed on the second connecting pipe 41. Both ends of the second connecting pipe 41 are connected to the reaction chamber 11, and the liquid inlet of the second connecting pipe 41 is located above the ultrasonic emitting component 2, while the vent and the liquid outlet of the second connecting pipe 41 are located below the ultrasonic emitting component 2. The circulation pump 42 is used to provide circulation power for the liquid entering the circulation channel. This arrangement allows the circulating liquid and the gas to be reacted to enter the reaction chamber 11 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.

[0061] See Figure 1 When the liquid level in the reaction chamber 11 is higher than the inlet end of the second connecting pipe 41, the liquid can overflow into the second connecting pipe 41. At this time, when the circulation pump 42 is turned on, the liquid in the second connecting pipe 41 can flow back into the reaction chamber 11 from the outlet end of the second 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.

[0062] Specifically, see Figure 1 The second cover 14 is provided with a liquid inlet 141, and the liquid outlet end of the second connecting pipe 41 is provided with a connecting valve 43. The second 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.

[0063] For example, the connecting valve 43 is a three-way valve.

[0064] Optionally, see Figure 1 and Figure 2 The ultrasonic transmitting assembly 2 includes multiple ultrasonic transducers 21 and several ultrasonic absorbers 22. The multiple ultrasonic transducers 21 are arranged at intervals along the vertical direction, and an ultrasonic absorber 22 is arranged between any two adjacent ultrasonic transducers 21. A serpentine reaction channel is formed between the multiple ultrasonic transducers 21, through which liquids and gases can pass. The ultrasonic transducers 21 are configured to emit ultrasonic waves, and the ultrasonic absorbers 22 are configured to absorb reflected ultrasonic waves. The ultrasonic waves generated by the ultrasonic transducers 21 will propagate and reflect between two adjacent ultrasonic transducers 21. The reflected waves generated can be absorbed when they pass through the ultrasonic absorbers 22 between two ultrasonic transducers 21, which can significantly reduce the number of ultrasonic wave reflections and the energy loss from reflection. This disrupts the conditions for the formation of a standing wave field and reduces the interference between multiple ultrasonic waves, significantly simplifying the propagation path of the ultrasonic waves. It also helps to concentrate energy in the serpentine reaction channel, ensuring the uniformity of the number, trajectory, and distribution of microbubbles at various positions within the serpentine reaction channel, and improving the overall efficiency of the gas-liquid reaction. The extended length of the serpentine reaction channel not only increases the number of microbubbles generated, but also increases the contact time between gas and liquid within the ultrasonic emission component 2, thereby further improving the efficiency and effectiveness of the gas-liquid reaction.

[0065] 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%.

[0066] For example, see Figure 2 The ultrasonic transmitting component 2 includes three ultrasonic transducers 21 and two ultrasonic absorbers 22.

[0067] In this embodiment, see Figure 2 The 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.

[0068] 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.

[0069] For example, the reaction chamber 11 has a circular cross-sectional shape, and 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.

[0070] In this embodiment, 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] In this embodiment, 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.

[0075] 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.

[0076] In this embodiment, see Figure 1 and Figure 2 The gas-liquid reaction device also includes a support 3, which is disposed within the reaction chamber 11 and detachably connected to the reaction body 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 body 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.

[0077] For example, the support 3 is detachably connected to the reaction chamber 11 by bolts.

[0078] Specifically, see Figure 2 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 are circumferentially limited by the annular frame to complete the stable installation of the ultrasonic transmitting component 2 on the support 3.

[0079] In this embodiment, see Figure 1 The gas-liquid reaction apparatus also includes an ultrasonic controller 61, which is located on the reaction body 1 and electrically connected to the ultrasonic transmitting component 2, and is used to control the opening and closing of the ultrasonic transmitting component 2. This configuration improves the automation level of the gas-liquid reaction apparatus and facilitates operation by staff.

[0080] For example, the ultrasonic controller 61 is connected to the ultrasonic transmitting assembly 2 via a wire 611, and a protective tube is fitted on the wire 611 to prevent the liquid in the reaction chamber 11 from damaging the wire 611.

[0081] Optionally, see Figure 1 The gas-liquid reaction device also includes a control module 6, which is electrically connected to the ultrasonic emission component 2, the circulation component 4 and the exhaust gas treatment component 5. The control module 6 is used to control the working status of the ultrasonic emission component 2, the circulation component 4 and the exhaust gas treatment component 5 to improve the automation level of the gas-liquid reaction device.

[0082] 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.

[0083] 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.

[0084] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
