Description

TECHNICAL FIELD

[0001] The utility model relates to production equipment technical field, especially a tail gas treatment system. BACKGROUND

[0002] In boron diffusion process, the treatment of tail gas is an important link in the process. The traditional tail gas treatment method is to pass the tail gas into water after preliminary cooling, and use hydrolysis reaction to keep boric oxide in the liquid bottle. However, this treatment method has obvious defects, mainly in the insufficient contact area of boric oxide and water, leading to incomplete dissolution process. Specifically, boric oxide presents large bubble state when it is passed into water, and the contact area with water is limited, resulting in the accumulation of B2O3 white powder in the pipeline. This accumulation will cause a series of process problems, such as abnormal increase of pump speed, pump membrane damage, shortening of equipment running time, finally leading to unstable process pressure, affecting film uniformity and reducing product yield.

[0003] The prior art mainly adopts three treatment schemes: using vacuum pump to form pressure difference between pump and furnace pipe to drive tail gas through water bottle; using spray device for gas cooling and absorption; or using water bottle dissolution scheme with serpentine plate to increase the dissolution path of gas in liquid water. But these schemes still have significant defects: under the action of vacuum pump, the system often has the problem of too high pump speed, leading to decreased pumping capacity, making it difficult to reach the required vacuum degree of the process, and easily causing process alarm. At the same time, the contact efficiency of gas and water is low, which is manifested in that the large gas bubbles cannot fully contact the water surface, the gas-water contact time is short, and the fixed serpentine plate can only play a simple blocking role and cannot realize efficient mixing. In addition, the venturi tube treatment structure commonly used in chemical industry performs well under normal pressure conditions, but it is not suitable for boron diffusion tail gas treatment in vacuum environment.

[0004] These technical problems urgently need a new solution that can improve the system exhaust capacity in vacuum state, ensure that the required vacuum degree of the process is maintained when the performance of the vacuum pump decreases, and realize efficient mixing of gas and water to improve the dissolution efficiency.

[0005] In view of the above problems, the prior art needs to be improved. UTILITY MODEL CONTENT

The embodiments described below with reference to the accompanying drawings are exemplary and are for the purpose of explaining the present application only, and cannot be understood as limiting the present application.

[0030] A tail gas treatment system according to embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numerals indicate the same or similar elements and / or functionality throughout the several views.

[0031] A tail gas treatment system according to embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numerals indicate the same or similar elements and / or functionality throughout the several views. Figure 1 , including a high-temperature diffusion furnace 1, a pressurized liquid mixing device 6, and a first pipeline 612, the pressurized liquid mixing device 6 is in communication with the high-temperature diffusion furnace 1 through the first pipeline 612, and the pressurized liquid mixing device 6 collects and processes waste gas and waste liquid.

[0032] The pressurized liquid mixing device 6 is in communication with the high-temperature diffusion furnace 1 through the first pipeline 612 and is responsible for collecting and processing waste gas and waste liquid. The pressurized liquid mixing device 6 can include the liquid mixing cavity 602, one end of the liquid mixing cavity 602 along the first direction is provided with the gas inlet 601, and one end of the first pipeline 612 is in communication with the gas inlet 601. Further, the pressurized liquid mixing device 6 can further include the gas injection member 604 and the gas blocking member 603, the gas injection member 604 is installed in the liquid mixing cavity 602 along the first direction, and the gas blocking member 603 is installed in the pressurized liquid mixing device 6 and located at one end of the gas injection member 604 close to the gas inlet 601. In addition, the pressurized liquid mixing device 6 can further include the first cooling member 605, and the first cooling member 605 is installed on the outer wall of the liquid mixing cavity 602.

[0033] Specifically, the design of the pressurized mixing device 6 ensures that the exhaust gas and liquid waste can be effectively collected and treated. For example, by providing the gas injection member 604 and the gas baffle 603, the mixing effect of gas and liquid can be enhanced, thereby improving the treatment efficiency of the exhaust gas and liquid waste. As a preferred embodiment, the pressurized mixing device 6 can further include the exhaust port 611, which is provided on the outer wall of the mixing cavity 602 and communicates with the inside of the mixing cavity 602, and the exhaust port 611 is provided at the end of the first cooling member 605 away from the gas inlet 601.

[0034] Therefore, the tail gas treatment system of the present application ensures that the exhaust gas and liquid waste can be effectively collected and treated through the cooperation of the high-temperature diffusion furnace 1 and the pressurized mixing device 6, thereby solving the problem of collection and treatment of exhaust gas and liquid waste in the tail gas treatment system. Compared with the prior art, the technical scheme of the present application has higher treatment efficiency and better mixing effect, and can more effectively solve the problem of treatment of exhaust gas and liquid waste.

[0035] In some embodiments of the present application, as shown in Figure 2 The pressurized mixing device 6 includes a mixing cavity 602, one end of the mixing cavity 602 is provided with a gas inlet 601 along a first direction, and one end of the first pipeline 612 communicates with the gas inlet 601.

[0036] Specifically, the design of the mixing cavity 602 is to ensure that the exhaust gas and liquid waste can effectively enter the cavity for treatment. The provision of the gas inlet 601 enables the exhaust gas and liquid waste to directly enter the mixing cavity 602 through the first pipeline 612, thereby realizing the continuous collection and treatment of the exhaust gas and liquid waste. As a preferred embodiment, the mixing cavity 602 can be made of corrosion-resistant materials to ensure its stability and durability during treatment of exhaust gas and liquid waste. In addition, the connection mode of the first pipeline 612 can be sealed connection to prevent leakage of exhaust gas and liquid waste during transmission.

[0037] Therefore, the pressurized mixing device 6 ensures that the exhaust gas and liquid waste can effectively enter the mixing cavity 602 for treatment by providing the mixing cavity 602 and the gas inlet 601. The connection of the first pipeline 612 further ensures the effective connection between the high-temperature diffusion furnace 1 and the pressurized mixing device 6, thereby realizing the continuous collection and treatment of the exhaust gas and liquid waste.

[0038] Briefly and deeply, the technical scheme is summarized as follows: the liquid mixing cavity 602 and the gas inlet 601 are arranged to ensure that the waste gas and waste liquid can effectively enter the liquid mixing cavity 602 for treatment. The first pipeline 612 is connected to further ensure the effective connection between the high-temperature diffusion furnace 1 and the pressurized liquid mixing device 6, so that the continuous collection and treatment of the waste gas and waste liquid are realized. Compared with the prior art, the technical scheme has the advantages that the connection problem between the pressurized liquid mixing device 6 and the high-temperature diffusion furnace 1 can be effectively solved, and the effective collection and treatment of the waste gas and waste liquid are ensured.

[0039] In some embodiments of the present application, as shown in Figure 2 The pressurized liquid mixing device 6 further comprises a gas injection member 604 and a gas blocking member 603. The gas injection member 604 is installed in the liquid mixing cavity 602 along the extension direction of the liquid mixing cavity, and the gas blocking member 603 is installed in the pressurized liquid mixing device 6 and located at one end of the gas injection member 604 close to the gas inlet 601. Figure 1

[0040] Specifically, the gas injection member 604 can be designed in various forms, for example, it can be a tubular structure with multiple small holes, or a cylindrical body with a spiral groove, which can effectively uniformly inject gas into the liquid mixing cavity 602. The gas blocking member 603 can be a flat plate structure or a ring structure with a groove, which mainly blocks the gas injected by the gas injection member 604 to form a stable flow path in the liquid mixing cavity 602, so that the water vapor and waste gas can be fully mixed.

[0041] As a preferred embodiment, the materials of the gas injection member 604 and the gas blocking member 603 can be selected as non-metallic materials resistant to corrosion, such as polytetrafluoroethylene (PTFE), to ensure their long-term stability during the treatment of waste gas and waste liquid. In addition, the installation positions of the gas injection member 604 and the gas blocking member 603 can be realized by precise machining and assembly technology, to ensure their accurate positions in the liquid mixing cavity 602.

[0042] ​Therefore, the pressurized liquid mixing device 6 ensures that the gas injection member 604 is installed along a first direction and the gas blocking piece 603 is located at one end of the gas injection member 604 close to the gas inlet 601 by installing the gas injection member 604 and the gas blocking piece 603 in the liquid mixing cavity 602. This design helps to optimize the flow path of the gas in the liquid mixing cavity 602 and improve the mixing efficiency of the gas, thereby more effectively treating the exhaust gas and liquid waste. By precisely controlling the positions of the gas injection member 604 and the gas blocking piece 603, the system can more effectively achieve gas-liquid mixing and improve the overall performance of the exhaust treatment system.

[0043] Compared with the prior art, the technical scheme of the present application significantly improves the efficiency of gas-liquid mixing by optimizing the installation positions of the gas injection member 604 and the gas blocking piece 603, and reduces the problem of uneven distribution of gas in the liquid mixing cavity 602. This not only improves the treatment efficiency of exhaust gas and liquid waste, but also reduces the maintenance cost and downtime of the equipment, thereby improving the reliability and stability of the system.

[0044] In some embodiments of the present application, as shown in Figure 2 The pressurized liquid mixing device 6 further comprises a first cooling member 605 installed on the outer wall of the liquid mixing cavity 602.

[0045] Specifically, the first cooling member 605 can be implemented in various ways, for example, water cooling or air cooling can be used to cool the liquid mixing cavity 602. As a preferred embodiment, the first cooling member 605 can be made of materials with good thermal conductivity, such as copper or aluminum, and its surface can be provided with fins to increase the heat dissipation area. Further, the first cooling member 605 can also be connected with an external cooling system to realize continuous cooling of the liquid mixing cavity 602 by circulating cooling medium.

[0046] Therefore, the pressurized liquid mixing device 6 realizes cooling treatment of the exhaust gas and liquid waste by installing the first cooling member 605 on the outer wall of the liquid mixing cavity 602. The role of this technical feature is that by installing the cooling member, the temperature of the exhaust gas and liquid waste in the liquid mixing cavity 602 can be effectively reduced, thereby improving the treatment efficiency and effect of the exhaust gas and liquid waste. This cooling treatment helps to ensure stable flow and effective mixing of the exhaust gas and liquid waste in the pressurized liquid mixing device 6, thereby improving the performance and stability of the entire exhaust treatment system. Compared with the prior art, the technical scheme of the present application significantly improves the cooling effect of the exhaust gas and liquid waste by adding a cooling member, reduces temperature fluctuations in the system, and improves the treatment efficiency and service life of the equipment.

[0047] In some embodiments of the present application, as shown inFigure 2 As shown, the pressurized mixing device 6 further comprises an exhaust port 611, which is arranged on the outer wall of the mixing cavity 602 and communicates with the interior of the mixing cavity 602, and the exhaust port 611 is arranged at the end of the first cooling member 605 away from the air inlet port 601.

[0048] Specifically, the arrangement of the exhaust port 611 enables the exhaust gas and water vapor to be effectively discharged from the mixing cavity 602 after being treated and cooled to form waste liquid. The position of the exhaust port 611 away from the air inlet port 601 avoids the backflow problem caused by insufficient gas mixing. As a preferred embodiment, the exhaust port 611 can be connected by a pipeline to ensure that the liquid can flow smoothly out of the mixing cavity 602. The exhaust port 611 can be arranged at the other end of the first cooling member 605 to utilize the structural characteristics of the cooling member to ensure that the exhaust gas that has not been sufficiently mixed with water vapor cannot pass through the exhaust port 611.

[0049] Therefore, this design not only solves the technical problem of the position of the exhaust port 611 for discharging waste liquid after treating exhaust gas in the pressurized mixing device 6, but also improves the processing efficiency and stability of the system. Compared with the prior art, the pressurized mixing device 6 of the present application can more effectively avoid the problem of insufficient gas mixing when treating exhaust gas and waste liquid, thereby improving the performance of the overall system.

[0050] In some embodiments of the present application, as shown in Figure 1 As shown, the tail discharge treatment system further comprises the exhaust pipe 9, the third switch member 7 and the power member 8, one end of the exhaust pipe 9 is connected to the exhaust port 611, the other end of the exhaust pipe 9 is connected to the power member 8, and the third switch member 7 is arranged on the exhaust pipe 9.

[0051] Specifically, the exhaust pipe 9 is used to connect the exhaust port 611 and the power member 8 to ensure that the treated exhaust gas can be effectively discharged. The arrangement of the third switch member 7 provides control over the exhaust pipe 9, so that the exhaust gas discharge process can be flexibly adjusted under different process conditions. The addition of the power member 8 further improves the exhaust efficiency of the system, ensuring that the system can maintain the required process vacuum pressure value even when the performance of the vacuum pump decreases.

[0052] As a preferred embodiment, the power member 8 can adopt an electric pump or a pneumatic pump to enhance the exhaust capacity of the exhaust pipe 9 by providing power. The third switch member 7 can adopt a solenoid valve or a manual valve to achieve precise adjustment of the flow of waste liquid in the exhaust pipe 9 through control.

[0053] Therefore, by introducing the exhaust pipeline 9, the third switch 7 and the power unit 8, the application enhances the liquid discharge capacity and the gas-water mixing sufficiency of the exhaust treatment system. The exhaust pipeline 9 connects the exhaust port 611 and the power unit 8, ensuring that the mixed exhaust liquid can be effectively discharged; the third switch 7 provides control over the exhaust pipeline 9, allowing flexible adjustment of the exhaust process under different process conditions. The addition of the power unit 8 further improves the exhaust efficiency of the system, ensuring that the system can maintain the required process vacuum pressure value even when the vacuum pump performance is reduced. These features work together to improve the overall performance of the exhaust treatment system, particularly in terms of gas-water mixing and liquid discharge capacity, thereby solving the technical problems of gas-water mixing sufficiency and exhaust liquid discharge in the exhaust treatment system.

[0054] In some embodiments of the application, as shown in Figure 2 As shown in the application, the pressurized liquid mixing device 6 forms an evaporation chamber 610 in the liquid mixing cavity 602 by adding a heating element 609, so that the liquid in the liquid mixing cavity 602 can be heated and evaporated to form water vapor. Water vapor mixes with exhaust gas, increasing the contact area between exhaust gas (including boron oxide) and liquid, thereby improving the dissolution efficiency of the exhaust gas. The evaporation chamber 610 is located at the end of the gas injection element 604 away from the gas inlet 601, ensuring that the exhaust gas can fully contact the heated liquid after entering the pressurized liquid mixing device 6, further promoting the dissolution of boron oxide. The installation position of the heating element 609 is close to the evaporation chamber 610, ensuring the uniformity and effectiveness of the heating effect, thereby solving the problem of incomplete dissolution of boron oxide in the exhaust gas, reducing the accumulation of white powdery boron oxide in the exhaust, and improving the stability of the process and the yield of the product.

[0055] Specifically, the heating element 609 can be achieved by electric heating, steam heating or hot oil heating, etc. The electric heating method can directly heat the liquid mixing cavity 602 by resistance wire or electric heating tube, the steam heating method can transfer heat to the liquid mixing cavity 602 by an external steam source, and the hot oil heating method can uniformly distribute heat to the liquid mixing cavity 602 by a circulating hot oil system. As a preferred embodiment, the electric heating method is widely used because it is easy to control and adjust the temperature.

[0056] Therefore, the pressurized liquid mixing device 6 forms water vapor by heating the liquid, increases the contact area of the tail gas and the liquid, and improves the dissolution efficiency of boron oxide. The design of the evaporation cavity 610 ensures that the tail gas is in sufficient contact with the heated liquid, and the reasonable installation position of the heating element 609 ensures the uniformity and effectiveness of the heating effect. These technical means work together to solve the problem of incomplete dissolution of boron oxide in the tail gas, reduce the accumulation of white powder of boron oxide in the tail gas, and improve the stability of the process and the yield of the product. Compared with the prior art, the technical scheme of the present application has significant advantages in improving the dissolution efficiency, reducing powder accumulation, improving process stability and product yield.

[0057] In some embodiments of the present application, as shown in Figure 2 The pressurized liquid mixing device 6 further comprises a second pipeline 2, one end of the second pipeline 2 is communicated with the evaporation cavity 610, and the other end of the second pipeline 2 is provided with the first switch element 607 and the one-way switch element 606. The first switch element 607 is arranged between the evaporation cavity 610 and the one-way switch element 606.

[0058] Specifically, the second pipeline 2 is designed to connect the evaporation cavity 610 with the external pipeline, and the first switch element 607 and the one-way switch element 606 are arranged on the pipeline to control the connection state of the evaporation cavity 610 and the external pipeline. The first switch element 607 is arranged between the evaporation cavity 610 and the one-way switch element 606, which can control the on-off of the evaporation cavity 610 and the external pipeline, and the one-way switch element 606 ensures that the gas and liquid can only flow in one direction to prevent backflow. As a preferred embodiment, the first switch element 607 can adopt an electromagnetic valve or a manual valve, and the one-way switch element 606 can adopt a one-way valve or a check valve.

[0059] Therefore, the pressurized liquid mixing device 6 connects the evaporation cavity 610 with the external pipeline by arranging the second pipeline 2, and arranges the first switch element 607 and the one-way switch element 606 on the pipeline to control the connection state of the evaporation cavity 610 and the external pipeline. The first switch element 607 is arranged between the evaporation cavity 610 and the one-way switch element 606, which can control the on-off of the evaporation cavity 610 and the external pipeline, and the one-way switch element 606 ensures that the gas and liquid can only flow in one direction to prevent backflow. This design solves the control problem of the connection of the evaporation cavity 610 and the external pipeline in the pressurized liquid mixing device 6 by accurately controlling the connection of the evaporation cavity 610 and the external pipeline, and ensures the stable operation and effective treatment of the system.

[0060] Further, compared with the prior art, the application has the advantages that by setting the second pipeline 2 and the corresponding switch piece, the connection state of the evaporation cavity 610 with the external pipeline is accurately controlled, the backflow of gas and liquid is avoided, and the stability and processing efficiency of the system are improved. Specifically, the setting of the first switch piece 607 and the one-way switch piece 606 enables the system to flexibly adjust the connection state of the evaporation cavity 610 with the external pipeline during operation as needed, thereby optimizing the waste gas and waste liquid processing process.

[0061] In some embodiments of the present application, as shown in Figure 2 The liquid discharge pipeline 613 is provided with the second switch piece 608, and the second switch piece 608 controls the discharge of the liquid.

[0062] Specifically, the design of the liquid discharge pipeline 613 enables the liquid to be discharged at a specific position, ensuring the accuracy of the flow path and control point of the liquid in the pressurized mixed liquid device 6. The setting of the second switch piece 608 enables the operator to control the discharge of the liquid as needed, thereby achieving accurate control of the liquid discharge. As a preferred embodiment, the second switch piece 608 can adopt an electric valve or a manual valve to adapt to different operation requirements. In addition, the liquid discharge pipeline 613 can be made of a corrosion-resistant material to ensure its long-term stability in a high-pressure and corrosive environment.

[0063] Therefore, the pressurized mixed liquid device 6 achieves accurate control of the liquid discharge by setting the liquid discharge pipeline 613 and the second switch piece 608. One end of the liquid discharge pipeline 613 is connected to the second pipeline 2, and the connection point is located between the first switch piece 607 and the evaporation cavity 610, ensuring the discharge of the liquid at a specific position. The setting of the second switch piece 608 enables the operator to control the discharge of the liquid as needed, thereby solving the control problem of the liquid discharge in the pressurized mixed liquid device 6.

[0064] Compared with the prior art, the technical scheme of the present application has the following advantages: first, by setting the liquid discharge pipeline 613 and the second switch piece 608, accurate control of the liquid discharge is achieved, avoiding unnecessary retention and waste of the liquid in the pressurized mixed liquid device 6. Second, the design of the liquid discharge pipeline 613 ensures the discharge of the liquid at a specific position, improving the working efficiency and stability of the device. Finally, the flexible control of the second switch piece 608 enables the operator to adjust the discharge amount of the liquid according to actual needs, further improving the adaptability and practicality of the device.

[0065] In some embodiments of the present application, as shown in Figure 1 The second cooling member 4, the vacuum member 3 and the fourth switching member 5 are arranged on the first pipeline 612, and the second cooling member 4 and the fourth switching member 5 are arranged on both sides of the vacuum member 3, and the fourth switching member 5 is arranged close to the pressurized mixed liquid device 6.

[0066] The second cooling member 4 is used for further cooling the exhaust gas, the vacuum member 3 is used for generating negative pressure in the system, and the fourth switching member 5 is used for controlling the flow of the exhaust gas. These components work together on the first pipeline 612 to ensure that the exhaust gas is properly cooled and pressure-regulated before entering the pressurized mixed liquid device 6, thereby improving the efficiency of exhaust gas treatment and the stability of the system. As a preferred embodiment, the second cooling member 4 can be cooled by water cooling (such as a cooling bottle) or air cooling, the vacuum member 3 can generate negative pressure by using a vacuum gauge, a mechanical pump or a molecular pump, and the fourth switching member 5 can be controlled by using an electromagnetic valve or a pneumatic valve.

[0067] Therefore, by arranging the second cooling member 4, the vacuum member 3 and the fourth switching member 5 on the first pipeline 612, the problems of insufficient exhaust gas treatment, incomplete dissolution and unstable system pressure can be effectively solved. Specifically, the arrangement of the second cooling member 4 allows the exhaust gas to be further cooled before entering the pressurized mixed liquid device 6, which helps to improve the dissolution efficiency of the exhaust gas; the arrangement of the vacuum member 3 generates negative pressure in the system, which helps to improve the exhaust capacity of the system; and the arrangement of the fourth switching member 5 can accurately control the flow of the exhaust gas, ensuring the stability of the system. Compared with the prior art, the technical solution of the present application has significant advantages in improving the efficiency of exhaust gas treatment and the stability of the system.

[0068] An embodiment of the exhaust treatment system of the present application is described below.

[0069] As shown in Figure 1 , Figure 2As shown, in the operation of the tail gas treatment system, first, the first switch 607 is opened, water is added to the evaporation cavity 610 to about 1 / 3 of the height, the heating element 609 is opened to heat the liquid in the evaporation cavity 610, and after the water evaporates, it is sprayed onto the gas blocking piece 603 through the gas spraying element 604 at high speed, the high-speed steam is folded back through the gas blocking piece 603, and then sprayed onto the inner wall of the mixed liquid cavity 602. The steam condenses into water on the inner wall of the mixed liquid cavity 602, and the solid and dust in the tail gas are dissolved in the water and left at the bottom of the steam cavity. Insoluble gas is discharged from the exhaust port 611 to the exhaust pipeline 9 and then discharged to the outside of the system through the power element 8. Wherein, after each production process cycle, the second switch 608 is opened to discharge the water solution after the treatment of the tail gas, and new pure water is replaced to restore the solubility of the tail gas.

[0070] It should be noted that in the tail gas treatment system of the above embodiment, one said booster mixed liquid device 6 can be provided, or a plurality of said booster mixed liquid devices 6 can be provided to enhance the filtering effect. Wherein, "a plurality of" in the utility model represents two or more, which will not be repeated here.
