Description

Technical Field

[0001] This invention belongs to the field of exhaust gas treatment technology, specifically a purification treatment device for the reuse of sulfonated exhaust gas. Background Technology

[0002] Sulfonated products are widely used in cosmetics, textiles, emulsion polymerization, mineral processing, pesticides, soil remediation and rubber. The sulfonation reaction is a chemical reaction in which hydrogen atoms in organic compounds are replaced by sulfonic acid groups in sulfuric acid molecules. Sulfur trioxide, sulfur dioxide and chlorine are usually used as sulfonating agents. The exhaust gas produced by the reaction also contains some unreacted sulfur oxides, so purification treatment equipment is needed to purify the sulfonation exhaust gas.

[0003] A Chinese patent with publication number CN205252880U discloses an alkaline scrubbing tower for tail gas treatment in a sulfonation process. This alkaline scrubbing tower effectively blocks small Na2SO3 and Na2SO4 particles from adhering to the water-saturated tail gas through upper and lower Pall ring packing layers, ensuring that the water-saturated tail gas after the reaction is free of gas droplets and solid particles. Before being discharged into the atmosphere, the water-saturated tail gas passes through a wire mesh packing layer to reduce its moisture content, ensuring that the final emitted tail gas meets the required standards. Because the number of alkali solution circulations during the treatment process is reduced, the working cycle of tail gas treatment in the sulfonation process is greatly reduced, thus lowering equipment energy consumption.

[0004] In current technologies, when treating exhaust gas, after the exhaust gas is transported to the purification equipment, it directly enters the packing layer for purification. This method results in the exhaust gas concentrating in a certain area of ​​the packing layer, causing excessive local purification load and insufficient purification in other areas, thus reducing the overall utilization rate and purification efficiency of the packing.

[0005] Therefore, the present invention provides a purification treatment device for the reuse of sulfonation tail gas. Summary of the Invention

A screw is fixedly installed at the output end of the drive motor. An extrusion plate is slidably installed on the inner wall of the tower body. The extrusion plate is located below the partition plate. The outer wall of the screw is threadedly connected to the inner wall of the extrusion plate.

[0011] Preferably, a positioning ring is fixedly installed on the inner wall of the tower body, the outer wall of the partition is slidably connected to the inner wall of the positioning ring, and the end of the screw away from the drive motor is fixedly connected to the axis of the partition.

[0012] Preferably, a plurality of limiting plates are slidably installed on the inner wall of the partition, and a stirring rod is fixedly installed on the bottom of each limiting plate, and the outer wall of the stirring rod is slidably connected to the inner wall of the partition.

[0014] Preferably, the elastic component includes a positioning plate symmetrically fixedly installed on the outer wall of the packing layer, and positioning columns symmetrically fixedly installed on the inner wall of the tower body. The outer walls of the positioning columns are slidably connected to the inner walls of the positioning plates, and a set of elastic elements B are fixedly installed between the positioning plates and the tower body.

[0015] Preferably, the spraying assembly includes an alkali solution container, which is fixedly installed on the outer wall of the tower body.

[0017] The beneficial effects of this invention are as follows: 1.

This uniform distribution ensures that the tail gas is in full contact with the purification medium in the packing layer, avoiding situations where the local concentration of tail gas is too high or too low in the packing layer, thereby improving the removal efficiency of harmful substances in the tail gas by the packing layer, and making the purification effect more uniform and stable.

[0018] 2. The purification treatment equipment for sulfonation tail gas reuse described in this invention uses a reciprocating lifting motion of an extrusion component. This periodic motion can precisely control the timing and flow rate of sulfonation tail gas purification. When the extrusion component descends, the tail gas enters the tower body through the inlet pipe and temporarily accumulates between the extrusion component and the homogenizing component. When the extrusion component rises, it compresses the accumulated tail gas, forming a regular tail gas treatment process, making the entire purification process more orderly and controllable.

[0019] 3. The purification treatment equipment for sulfonated tail gas recycling described in this invention uses a uniform component and an extrusion component working together. The extrusion component provides pressure to make the tail gas overcome the resistance of the uniform component and pass through. The uniform component then shapes and homogenizes the passing tail gas. The two work together to form a highly efficient control system for tail gas entering the packing layer, which ensures that the tail gas has sufficient power to pass through the uniform component and that the tail gas enters the packing layer in the best condition for purification treatment.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 8As shown in the figure, a purification treatment device for sulfonation tail gas recycling according to an embodiment of the present invention includes a tower body 1. An air inlet pipe 2 is fixedly installed on the inner wall of the tower body 1, and a one-way valve 3 is fixedly installed on the outer wall of the air inlet pipe 2. A packing layer 4 is slidably installed on the inner wall of the tower body 1. A uniform distribution component is arranged below the packing layer 4 to ensure that the tail gas enters the packing layer 4 uniformly. A compression component is arranged below the uniform distribution component to provide power for the tail gas to pass through the uniform distribution component. A spray component for providing alkaline solution for purification is arranged on one side of the tower body 1. During the purification process, the compression component reciprocates and rises. A vent hole (not shown in the figure) is opened near the bottom of the tower body 1 to provide conditions for the rising and falling of the compression component. During descent, the sulfonated tail gas enters the interior of tower 1 through inlet pipe 2. Inside tower 1, the tail gas is temporarily blocked by the homogenizing component, remaining between the extrusion and homogenizing components. When the extrusion component rises, it compresses the sulfonated tail gas inside tower 1. Because a one-way valve 3 is installed on inlet pipe 2, the sulfonated tail gas cannot flow back through inlet pipe 2. Therefore, the increased pressure of the compressed sulfonated tail gas pushes open the homogenizing component, allowing it to pass through. As the sulfonated tail gas passes through the homogenizing component, it becomes evenly distributed under its influence, thus uniformly entering the packing layer 4. In summary, by setting up the homogenizing component, the sulfonated tail gas is evenly distributed as it passes through it before entering the packing layer 4. Uniform distribution ensures sufficient contact between the exhaust gas and the purification medium in the packing layer 4, preventing localized excessively high or low concentrations of the exhaust gas within the packing layer 4. This improves the removal efficiency of harmful substances in the exhaust gas by the packing layer 4, resulting in a more uniform and stable purification effect. The reciprocating lifting motion of the extrusion assembly precisely controls the timing and flow rate of the sulfonated exhaust gas purification. When the extrusion assembly descends, the exhaust gas enters the tower body 1 through the inlet pipe 2 and temporarily accumulates between the extrusion assembly and the uniform distribution assembly. When the extrusion assembly rises, it compresses the accumulated exhaust gas, forming a regular exhaust gas treatment process, making the entire purification process more orderly and controllable. The pressure generated when the extrusion assembly rises is the pressure generated by the sulfonated exhaust gas. The key power source for the gas passing through the uniform component is the pressure-driven method, which eliminates the need for additional complex power devices, simplifying the equipment structure. At the same time, the lifting speed and force of the extrusion component can be adjusted according to actual needs, thereby flexibly controlling the speed and pressure of the exhaust gas passing through the uniform component to meet the purification requirements under different working conditions. The uniform component and the extrusion component work together. The extrusion component provides pressure to make the exhaust gas overcome the resistance of the uniform component and pass through, while the uniform component shapes and homogenizes the passing exhaust gas. The two work together to form a highly efficient control system for the exhaust gas to enter the packing layer 4, which ensures that the exhaust gas has sufficient power to pass through the uniform component and that the exhaust gas enters the packing layer 4 in the best condition for purification treatment.

[0024] like Figures 2 to 8As shown, the uniform assembly includes a partition 5, which is located below the packing layer 4. The outer wall of the partition 5 is attached to the inner wall of the tower body 1. Several through slots 6 are evenly provided on the top of the partition 5. A lifting seat 7 is slidably installed on the inner wall of the partition 5. Several limiting posts 8 are slidably installed on the inner wall of the lifting seat 7. The end of the limiting post 8 away from the lifting seat 7 is fixedly connected to the inner wall of the partition 5. Several elastic elements A9 are fixedly installed between the lifting seat 7 and the partition 5. Several sealing components are provided at the bottom of the lifting seat 7. The connection point between the air inlet pipe 2 and the tower body 1 is located below the partition 5. When the exhaust gas enters the tower body 1, the through slots 6 are sealed by the sealing components. Therefore, the sulfonated exhaust gas entering the tower body 1 will stay below the partition 5. During the air intake process, the extrusion component descends. After the air intake is completed, the extrusion component begins to rise. The rising extrusion component will extrude the exhaust gas. After the exhaust gas is extruded, it will push up the sealing components, thereby opening the through slots 6. Since each sealing component is connected to the lifting seat 7, therefore All the through slots 6 open simultaneously. At this time, the elastic element A9 is in an extended state. After the through slots 6 open, the exhaust gas passes through each through slot 6, thus distributing evenly below the packing layer 4, and then entering the packing layer 4 in a uniform state. After the extrusion assembly completes the pushing work of the exhaust gas, the lifting seat 7 resets under the action of the elastic element A9, thereby causing the sealing assembly to seal the through slots 6 again. In summary, when the extrusion assembly compresses the exhaust gas to a certain pressure and lifts the sealing assembly, all the through slots 6 open simultaneously. This allows the exhaust gas to pass evenly through the partition 5 from multiple through slots 6 at the same time, ensuring that the exhaust gas can enter the packing layer 4 in a uniform state, providing a foundation for subsequent high-efficiency purification. After the extrusion assembly completes the pushing work of the exhaust gas, the lifting seat 7 automatically resets under the action of the elastic element A9, and the sealing assembly seals the through slots 6 again. This automatic reset function allows the uniform component to work in a cycle without frequent manual operation, improving the automation level and working efficiency of the equipment.

[0025] like Figures 5 to 8As shown, the sealing assembly includes a sealing frame 10, the top of which is fixedly connected to the bottom of the lifting seat 7. The outer wall of the sealing frame 10 is slidably connected to the inner wall of the through groove 6. Several exhaust holes 11 are symmetrically opened on the outer wall of the sealing frame 10. In the initial state, the sealing frame 10 fits tightly against the through groove 6, forming a reliable sealing structure, ensuring that the exhaust gas will only enter the packing layer 4 for purification under appropriate pressure conditions, thus ensuring the controllability and effectiveness of the purification process. When the extrusion assembly rises, the exhaust gas is compressed, increasing the pressure and thus lifting the sealing frame 10 upwards. After the 10 moves upward, the exhaust holes 11 on its surface will be opened. After the exhaust gas passes through each channel 6, it will be further dispersed through the exhaust holes 11. This can effectively prevent the exhaust gas from concentrating in a local area when it enters the packing layer 4. If the exhaust gas enters the packing layer 4 directly with a large airflow, it may cause local areas of the packing layer 4 to become oversaturated, while other areas fail to fully exert their purification effect. The dispersion of the exhaust holes 11 can make the exhaust gas evenly distributed in all parts of the packing layer 4, making full use of the purification capacity of the packing layer 4 and improving the uniformity and stability of the purification process.

[0026] like Figures 2 to 4As shown, the extrusion assembly includes a drive motor 12, which is fixedly installed at the bottom of the inner wall of the tower body 1. A screw 13 is fixedly installed at the output end of the drive motor 12. An extrusion plate 14 is slidably installed on the inner wall of the tower body 1, located below the partition 5. The outer wall of the screw 13 is threadedly connected to the inner wall of the extrusion plate 14. Limiting blocks 15 are symmetrically fixedly installed on the outer wall of the extrusion plate 14, and the outer wall of the limiting blocks 15 is slidably connected to the inner wall of the tower body 1. When the device is working, the drive motor 12 drives the screw 13 to rotate reciprocally. The screw 13, through its threaded engagement with the extrusion plate 14, causes the extrusion plate 14 to rise and fall. When the extrusion plate 14 descends, the sulfonated exhaust gas enters the inner side of the tower body 1 through the air inlet pipe 2. When the extrusion plate 14 rises, it compresses the exhaust gas and pushes it above the partition 5 for purification. Only when a certain pressure is reached can the sealing cover be opened to allow the exhaust gas to enter. The packing material is designed to flexibly adjust the amount of exhaust gas entering the packing according to the composition, concentration, and treatment requirements of the exhaust gas, avoiding insufficient purification or premature saturation of the packing due to excessive exhaust gas. By controlling the speed and direction of the drive motor 12, the lifting speed and force of the extrusion plate 14 can be precisely adjusted, thereby achieving precise control of the sulfonated exhaust gas pressure. Under different operating conditions, the flow rate, concentration, and composition of the sulfonated exhaust gas may vary. By adjusting the parameters of the drive motor 12, the extrusion plate 14 can apply appropriate pressure to the exhaust gas, ensuring that the exhaust gas can pass smoothly through the uniform component and enter the packing layer 4 evenly, while avoiding the purification effect due to excessive or insufficient pressure. It should be noted that the thickness of the extrusion plate 14 is greater than the diameter of the inlet pipe 2. Therefore, when the extrusion plate 14 is attached to the partition 5, the inlet pipe 2 will be blocked by the extrusion plate 14, thereby preventing the sulfonated exhaust gas from entering below the extrusion plate 14 and causing exhaust gas leakage.

[0027] like Figures 3 to 4 As shown, a positioning ring 16 is fixedly installed on the inner wall of the tower body 1. The outer wall of the partition plate 5 is slidably connected to the inner wall of the positioning ring 16. The end of the screw 13 away from the drive motor 12 is fixedly connected to the axis of the partition plate 5. The partition plate 5 is rotatably installed on the inner side of the positioning ring 16. At the same time, one end of the screw 13 is fixed to the partition plate 5. Therefore, when the screw 13 rotates, it will drive the partition plate 5 to rotate together. During the rotation of the partition plate 5, the position of the through groove 6 on it changes continuously, which is equivalent to providing channels for the exhaust gas to enter the packing layer 4 from different angles. This makes the exhaust gas more dispersed when passing through the through groove 6, avoiding the problem of excessive or insufficient local airflow caused by the exhaust gas always passing through a few fixed positions. Combined with the sealing and dispersion functions of the uniform component, it further improves the uniformity of the exhaust gas entering the packing layer 4, creating good conditions for efficient purification.

[0028] like Figure 4 and Figure 6As shown, several limiting plates 17 are slidably installed on the inner wall of the partition 5. A stirring rod 18 is fixedly installed at the bottom of each limiting plate 17, and the outer wall of the stirring rod 18 is slidably connected to the inner wall of the partition 5. The stirring rods 18 are distributed at the air inlet of the air inlet pipe 2. When the partition 5 rotates, the stirring rods 18 rotate accordingly. When the sulfonated tail gas enters the tower body 1 from the air inlet pipe 2 and accumulates below the partition 5, these stirring rods 18 can immediately stir the newly entered tail gas. Since the newly entered tail gas may have unstable airflow and uneven component distribution, the stirring action of the stirring rods 18 can quickly make the tail gas mix evenly, breaking up any potential localized mixing issues. The concentration difference prepares for the subsequent uniform entry into the packing layer 4 and efficient purification treatment. The stirring rod 18 is slidably connected to the partition plate 5. When the extrusion plate 14 is in contact with the partition plate 5, the stirring rod 18 will be squeezed into the inner side of the partition plate 5. During the air intake stage, the stirring rod 18 normally stirs the exhaust gas. When the extrusion plate 14 rises to squeeze the exhaust gas, the stirring rod 18 enters the inner side of the partition plate 5 and will not hinder the upward movement of the extrusion plate 14. This ensures that the extrusion plate 14 can smoothly squeeze and push the exhaust gas into the packing layer 4. At the same time, when the extrusion plate 14 descends and resets, the stirring rod 18 can extend again to continue stirring the exhaust gas, realizing seamless collaborative work between the components.

[0029] like Figures 3 to 6 and Figures 9 to 10 As shown, an mounting base 19 is fixedly installed on the inner wall of the packing layer 4. Several upper teeth 20 are fixedly installed on the bottom of the mounting base 19. Several support columns 21 are fixedly installed on the top of the partition 5. An mounting ring 22 is fixedly installed between the tops of the support columns 21. Several lower teeth 23 are fixedly installed on the top of the mounting ring 22. The lower teeth 23 and upper teeth 20 are staggered. An elastic component is provided on the outer wall of the packing layer 4. The upper teeth 20 are connected to the packing layer 4 via the mounting base 19, and the lower teeth 23 are connected to the partition 5 via the mounting ring 22 and support columns 21. When the partition 5 rotates, the lower teeth 23 rotate accordingly. During rotation, the lower teeth 23 compress the upper teeth 20, causing the upper teeth 20 to drive the mounting base 19 to vibrate up and down. When the mounting base 19 vibrates, it causes the packing layer 4 to spring back up and down. Under the action of the dynamic components, the packing particles in the packing layer 4 continuously undergo relative movement and positional changes as they vibrate up and down. This dynamic change breaks the fixed flow channels that the exhaust gas may form in the packing layer 4, allowing the exhaust gas to come into more full contact with the packing surface. Harmful substances in the exhaust gas have more opportunities to undergo purification processes such as adsorption and reaction with the active ingredients on the packing, thereby greatly improving purification efficiency and shortening purification time. In addition, the vibration of the packing layer 4 can improve mass transfer conditions. The vibration causes the liquid film on the surface of the packing to be constantly renewed, increasing the contact area and contact frequency between the exhaust gas and the liquid film, accelerating the mass transfer speed of harmful substances from the exhaust gas to the liquid film. At the same time, the vibration can also promote the diffusion of substances in the liquid film, improve mass transfer efficiency, and enable the purification medium to remove pollutants in the exhaust gas more effectively.

[0030] like Figures 1 to 2 As shown, the elastic component includes a positioning plate 24 symmetrically fixedly installed on the outer wall of the packing layer 4, and a positioning column 25 symmetrically fixedly installed on the inner wall of the tower body 1. The outer walls of the positioning columns 25 are slidably connected to the inner walls of the positioning plates 24. A set of elastic elements B26 are fixedly installed between the positioning plates 24 and the tower body 1. The positioning plates 24 are symmetrically fixed to the outer wall of the packing layer 4, and the positioning columns 25 are symmetrically fixed to the inner wall of the tower body 1. The two are slidably connected to form a vertical guide track. The packing layer 4 can only vibrate along the axial direction of the positioning columns 25 to avoid horizontal displacement or tilting and ensure vibration stability. When the packing layer 4 is subjected to external force, the elastic element B26 stores elastic potential energy. After the external force is removed, the elastic element B26 releases the potential energy and pushes the packing layer 4 to reset, forming reciprocating vibration, which provides conditions for the packing layer 4 to shake up and down.

[0031] like Figure 9 and Figure 11 As shown, the spray assembly includes an alkali solution container 27, which is fixedly installed on the outer wall of the tower body 1. A conveying pipe 28 connects the alkali solution container 27 and the tower body 1. A spray head 29 is fixedly installed at the end of the conveying pipe 28 away from the alkali solution container 27, and the spray head 29 is located above the packing layer 4. The alkali solution container 27 is used to contain alkali solution. When the device is in purification operation, the water pump inside the alkali solution container 27 is started, and the alkali solution is conveyed to the spray head 29 through the conveying pipe 28. Then, the alkali solution is evenly sprayed onto the surface of the packing layer 4 through the spray head 29. The packing layer 4 works with the alkali solution to purify the sulfonation tail gas.

[0032] like Figures 1 to 2 and Figure 11 As shown, the top of the partition 5 has several drainage channels 30, the inner wall of the tower body 1 has a guide channel 31, and the inner wall of the tower body 1 has several liquid inlets 32. All liquid inlets 32 are connected to the guide channels 31. A return pipe 33 connects the guide channels 31 to the alkali solution container 27. When the alkali solution passes through the packing layer 4, it falls onto the partition 5. The drainage channels 30 on the partition 5 allow the alkali solution to accumulate. During the rotation of the partition 5, the drainage channels 30 circulate and align with the liquid inlets 32. When the liquid inlets 32 are aligned, the alkali solution in the diversion channel 30 will enter the inner side of the guide channel 31 through the liquid inlet 32. The alkali solution entering the guide channel 31 will eventually flow back to the inner side of the alkali solution container 27 through the return pipe 33, so that the alkali solution can be recycled, reducing alkali solution waste and reducing material costs. This solution uses gravity and the rotational kinetic energy of the baffle 5 to achieve natural return. The alkali solution flows from the diversion channel 30 into the guide channel 31 through the liquid inlet 32, and then flows back to the alkali solution container 27 by gravity through the return pipe 33, without the need for additional power equipment.
