Description

Technical Field

[0001] This application relates to the field of waste gas purification equipment technology, and in particular to waste gas emission purification equipment and purification process for automotive anti-vibration expansion rubber production lines. Background Technology

[0002] The production of automotive anti-vibration expansion rubber mainly involves processes such as rubber mixing, vulcanization, and drying. These processes generate waste gases that damage the environment, requiring waste gas purification equipment to treat the collected waste gases before they are discharged. Existing waste gas purification equipment includes spray towers. The tower body is a vertical cylinder with a packing support plate at the bottom. The packing is placed on the support plate in a random or orderly manner. A packing pressure plate is installed above the packing to prevent it from being blown away by the rising airflow. Liquid is sprayed onto the packing from the spray components at the top of the tower and flows down along the surface of the packing. Waste gas is fed in from the bottom of the tower and flows counter-currently through the gaps in the packing layer. On the surface of the packing, the gas and liquid phases come into close contact for mass transfer. Then, the waste gas passes through the spray area and comes into contact with the spray liquid again, completing the purification of the waste gas. The purified gas passes through a demister layer and is discharged from the top of the tower.

[0003] However, in the operation of traditional spray towers, the liquid sprayed from the spray components flows from one packing to another. For the packing layer as a whole, the liquid flow direction can be considered random. However, for the packing close to the tower wall, the liquid flows towards the tower wall after passing through the contact point between the packing and the tower wall, and then flows down the tower wall. This part of the liquid flow returns to the packing layer. Therefore, the liquid flowing towards the tower wall near the packing layer can easily cause the liquid in the packing layer to flow towards the tower wall. After the liquid has flowed for a certain distance, the liquid flow rate in the center of the packing layer is relatively reduced, and the liquid flow sprayed from the spray components tends to converge towards the tower wall, which is the "tower wall effect". At the same time, part of the liquid sprayed from the cone-shaped surface of the spray components will directly spray onto the inner wall of the tower, causing the liquid flow at the top of the packing layer and part of the liquid flow passing through the packing layer to flow down the tower wall. This part of the liquid flow is difficult to effectively contact with the waste gas, which reduces the utilization efficiency of the sprayed liquid and leads to a decrease in the overall waste gas purification efficiency. Summary of the Invention

[0004] This application proposes a waste gas emission purification device and purification process for an automotive anti-vibration expansion adhesive production line. It has the advantages of reducing the amount of spray liquid flowing along the inner wall of the spray tower and improving the contact efficiency between the spray liquid and the waste gas, thereby solving the problem of reduced contact efficiency between the spray liquid and the waste gas caused by some of the spray liquid flowing along the tower wall in traditional spray towers.

[0005] To achieve the above objectives, this application adopts the following technical solution: exhaust gas purification equipment for automotive anti-vibration expansion rubber production line, including a tower body, an air inlet pipe fixedly installed on one side of the bottom of the tower body, a spray assembly fixedly installed on the top of the inner side of the tower body, a packing layer provided on the inner side of the tower body, and a drive mechanism, a rotating frame movably installed on the inner side of the tower body, a guide ring provided on the top of the rotating frame, a guide groove opened on the top surface of the rotating frame, and a plurality of liquid outlet holes opened on the bottom of the inner wall of the guide groove;

[0006] The guide ring is used to guide the wall flow into the guide channel, the guide channel is used to guide the collected liquid to the center of the rotating frame, and the drive mechanism can drive the rotating frame to rotate around the center line of the tower body, changing the horizontal position of the liquid outlet.

[0007] Furthermore, the packing layer includes a support plate and a pressure plate, both of which are fixedly connected to the tower body. Packing is provided between the support plate and the pressure plate. The number of rotating frames is set to match the number of packing layers. An air outlet is provided at the top of the tower body.

[0008] Furthermore, the driving mechanism includes two connecting plates fixedly connected to the top of the inner side of the tower body, a fixed cylinder fixedly connected between the two connecting plates, a drive shaft rotatably arranged on one side of the bottom of the fixed cylinder, a rotating seat fixedly sleeved on the shaft of the drive shaft, the number of rotating seats being adapted to the number of rotating frames, a liquid inlet pipe fixedly connected to one side of the fixed cylinder, and a connecting pipe fixedly connected to the other side of the fixed cylinder.

[0009] Furthermore, the driving mechanism also includes a rotating shaft and a transmission mechanism. The rotating shaft is rotatably connected to the fixed cylinder, and several blades are fixedly connected to the outer side of the rotating shaft. One end of the connecting pipe is connected to the spray assembly, and the rotating shaft drives the transmission shaft to rotate at a reduced speed through the transmission mechanism.

[0010] Furthermore, the transmission mechanism includes a transmission gear, which is fixedly sleeved with a rotating shaft, and a connecting gear is fixedly sleeved on the top of the transmission shaft, with the connecting gear meshing with the transmission gear.

[0011] Furthermore, a number of movable plates for sealing the liquid outlet holes are slidably arranged at the bottom of the inner wall of the guide channel. The movable plates have a number of connecting holes, the number of connecting holes being adapted to the number of liquid outlet holes sealed by the corresponding movable plates. An adjusting spring is fixedly connected to one side of the movable plate, and an adjusting mechanism is also included. The adjusting mechanism is used to drive the movable plate to move radially relative to the rotating frame, adjusting the corresponding state of the connecting holes and the liquid outlet holes.

[0012] Furthermore, the adjustment mechanism includes an adjustment plate, which is fixedly connected to the rotating seat. The outer wall surface of the adjustment plate has a wave-like shape. A connecting rod is fixedly connected to one side of the movable plate. An adjustment wheel is rotatably arranged on one side of the bottom of the connecting rod. The distance from the rotation center of the rotating frame to different liquid outlets in a plurality of liquid outlets of a single rotating frame is different.

[0013] Furthermore, a limiting rod is slidably sleeved on the inner side of the drive shaft, the top surface of the limiting rod is connected to the cavity of the fixed cylinder, the cross-section of the limiting rod is T-shaped, a return spring is movably sleeved on one end of the limiting rod, a through hole is opened on one side of the top of the drive shaft, a limiting block is fixedly sleeved on the rod body of the limiting rod, the number of limiting blocks is adapted to the number of rotating frames, a moving rod is fixedly connected to one side of the connecting rod, a fixed block is slidably sleeved on the outer side of the moving rod, and the fixed block is fixedly connected to the drive shaft.

[0014] The exhaust gas purification process of the automotive anti-vibration expansion rubber production line includes the following steps:

[0015] S1: The exhaust gas is introduced from the bottom of the tower and liquid is supplied into the spray assembly, so that the spray assembly sprays liquid to the bottom of the tower to purify the exhaust gas.

[0016] S2: The drive mechanism drives the transmission shaft to rotate, and the transmission shaft drives the corresponding rotating frame to rotate. At the same time, the liquid flow on the inner wall of the tower flows through the outer wall of the guide ring and falls into the guide groove.

[0017] S3: The liquid flows along the guide groove toward the center of the rotating frame. When the liquid flows through the outlet hole, it is discharged from the outlet hole. At the same time, the rotating frame rotates to change the horizontal position of the outlet hole, so that the liquid discharged from the outlet hole falls in the horizontal plane along the corresponding annular distribution.

[0018] S4: During the process of the exhaust gas passing through the tower cavity, it comes into contact with the liquid on the surface of the packing after passing through the liquid outlet and the liquid distribution of the spray component, and the exhaust gas comes into contact with the liquid discharged from the liquid outlet and the liquid output of the spray component, thus purifying the exhaust gas.

[0019] S5: The purified gas is discharged from the top of the tower after being demisted, and the liquid used for purification is recovered from the bottom of the tower.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The exhaust gas purification equipment for the automotive anti-vibration expansion adhesive production line provided in this application guides the liquid flowing on the inner wall of the tower into the guide channel through the guide ring. The liquid in the guide channel flows along the guide channel and is discharged at the liquid outlet. In conjunction with the drive mechanism, the rotating frame is rotated, which changes the position of the liquid outlet, so that the rotating frame arranges the liquid in a ring. This recovers and redistributes the wall flow, improves the overall utilization efficiency of the sprayed liquid, and ensures the uniformity of the liquid redistribution arrangement. It also prevents the liquid sprayed by the spray components from flowing to the inner wall of the tower and being difficult to return, which would reduce the contact efficiency between gas and liquid and improve the reliability of the purification equipment.

[0022] 2. The exhaust gas purification equipment for the automotive anti-vibration expansion adhesive production line provided in this application changes the relative position of the movable plate and the rotating frame through an adjustment mechanism, thereby changing the corresponding state of the connecting hole and the liquid outlet hole. In conjunction with the rotation of the rotating frame, compared with fixed-point liquid outlet, this purification equipment guides the collected wall flow along the ring when the liquid outlet hole is open, increasing the area of ​​the liquid distribution zone and ensuring the uniformity of liquid reception in the bottom packing layer. At the same time, when the liquid outlet hole is closed, liquid accumulates in the guide channel, preventing the liquid from flowing out of the first liquid outlet hole during the flow of the guide channel, which would result in only a small amount of liquid flowing out of some liquid outlet holes. This further ensures the uniformity of liquid distribution and improves the reliability of the exhaust gas purification equipment. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1, as Figures 1-8 The exhaust gas purification equipment for an automotive anti-vibration expansion rubber production line includes a tower body 1. An air inlet pipe 2 is fixedly installed on one side of the bottom of the tower body 1. The air inlet pipe 2 is used to connect with exhaust gas collection equipment to guide the exhaust gas into the tower body 1. An air outlet 3 is opened at the top of the tower body 1. (See reference...) Figure 2 A spray assembly 4 is fixedly installed on the top of the inner side of the tower body 1. The spray assembly 4 is used to spray liquid onto the inner side of the tower body to form a spray layer. The liquid sprayed down from the top of the tower comes into contact with the exhaust gas, and the pollutants in the exhaust gas are absorbed by the liquid or undergo chemical reactions, thereby achieving the purification of the exhaust gas.

[0037] A packing layer is installed on the inner side of tower body 1 near the top. (See reference) Figure 3The packing layer includes a support plate 5 and a pressure plate 6. Both the support plate 5 and the pressure plate 6 are fixedly connected to the tower body 1. Packing is provided between the support plate 5 and the pressure plate 6. The packing is placed on the support plate 5 in a random stacking manner, or it can be placed on the support plate 5 in a block-like manner. The pressure plate 6 is used to restrict the packing from being blown away by the rising airflow. The liquid sprayed by the spray assembly 4 can fall onto the packing and flow down along the gap surface of the packing. A demisting layer is provided at the top of the inner side of the tower body 1. The demisting layer can be a gas flow layer with a baffle plate demister, or it can be a gas flow layer with a wire mesh demister. The bottom of the tower body 1 is connected to the reflux assembly.

[0038] Before the exhaust gas is sprayed for purification, it can be pre-treated by filtration to remove large particulate dust. When the purification equipment is in use, the exhaust gas is sent in through the inlet pipe 2 at the bottom of the tower, and the spray component 4 sprays out liquid. The exhaust gas passes through the packing layer and comes into contact with the liquid that continuously passes through the gaps in the packing layer in a relatively countercurrent manner on the surface of the packing. After passing through the spray layer, during the contact between the liquid and the exhaust gas, the pollutants in the exhaust gas are absorbed by the liquid or undergo chemical reactions, thereby purifying the exhaust gas. The purified exhaust gas passes through the demister layer and is discharged from the outlet 3 at the top of the tower 1. The sprayed liquid is recovered through the reflux component.

[0039] Two connecting plates 26 are fixedly connected to the top of the inner side of the tower body 1, and a fixing cylinder 10 is fixedly connected between the two connecting plates 26. (See reference) Figure 6 A drive shaft 11 is rotatably mounted on one side of the bottom of the fixed cylinder 10. The drive shaft 11 is rotatably sleeved with the pressure plate 6. A rotating seat 18 is fixedly sleeved on the shaft body of the drive shaft 11. The rotating frame 7 is composed of a straight plate and an annular plate connected longitudinally and transversely. The rotating seat 18 is fixedly installed at the center position of the corresponding rotating frame 7, that is, the axis of the drive shaft 11 is collinear with the rotation center line of the rotating frame 7. The rotating seat 18 is rotatably sleeved with the corresponding support plate 5. The system also includes a drive mechanism.

[0040] The drive mechanism is used to drive the transmission shaft 11 to rotate. Specifically, the drive mechanism includes a rotating shaft 12, see [reference]. Figure 7 The rotating shaft 12 is rotatably connected to the fixed cylinder 10. Several blades 13 are fixedly connected to the outer side of the rotating shaft 12. The blades 13 and the rotating shaft 12 form an impeller. An inlet pipe 16 is fixedly connected to one side of the fixed cylinder 10, and a connecting pipe 17 is fixedly connected to the other side of the fixed cylinder 10. The impeller divides the cavity of the fixed cylinder 10 into several parts. The inlet pipe 16 is connected to the liquid supply mechanism. Liquid enters the fixed cylinder 10 from the inlet pipe 16 and flows out through the connecting pipe 17. The liquid flow can drive the impeller to rotate. One end of the connecting pipe 17 is connected to the spray assembly 4. A transmission gear 14 is fixedly sleeved at the bottom of the rotating shaft 12, and a connecting gear 15 is fixedly sleeved at the top of the transmission shaft 11. The connecting gear 15 and the transmission gear 14 mesh with each other.

[0041] Unlike liquid-driven systems, the drive mechanism can also be configured as a drive motor whose output end is connected to the drive shaft 11. The number of packing layers must be at least one. (See [reference]). Figure 3 A rotating frame 7 is movably installed on the inner side of the tower body 1. The number of rotating frames 7 is adapted to the number of packing layers, that is, a single packing layer is located between two adjacent rotating frames 7. The number of rotating seats 18 is adapted to the number of rotating frames 7. (See reference...) Figure 5 The top surface of the rotating frame 7 is provided with a guide groove 8, which is used to collect the wall flow and guide the wall flow to the center of the tower body 1. The bottom surface of the inner wall of the guide groove 8 is set as a horizontal plane, and the bottom of the inner wall of the guide groove 8 is provided with a liquid outlet hole 9, which is used to discharge the liquid collected in the guide groove 8 from the bottom of the rotating frame 7.

[0042] The number of liquid outlet holes 9 is set to a certain number, and the several liquid outlet holes 9 are arranged radially with uniform intervals, see reference. Figure 3 The top of the rotating frame 7 is equipped with a flow guide ring 25. The flow guide ring 25 located at the top of all packing layers is fixedly installed on the inner side of the tower body 1. (See reference) Figure 8 The guide ring 25 at the bottom of the packing layer is fixedly connected to the support plate 5. A gap is left between the guide ring 25 and the rotating frame 7 to avoid contact friction during the rotation of the rotating frame 7. The guide ring 25 is used to guide the wall flow to the guide groove 8.

[0043] In use, the liquid supply mechanism pumps the liquid used to purify the waste gas into the inlet pipe 16. The liquid enters the connecting pipe 17 through the inlet pipe 16 and the fixed cylinder 10, and is then sprayed out through the spray assembly 4. The liquid flow drives the impeller in the fixed cylinder 10 to rotate. The rotating shaft 12 of the impeller rotates, which drives the transmission gear 14 to rotate. The rotation of the transmission gear 14 drives the connecting gear 15 to rotate at a reduced speed. The connecting gear 15 drives the transmission shaft 11 to rotate. The transmission shaft 11 drives the rotating seat 18 to rotate, thereby driving the corresponding several rotating frames 7 to rotate slowly. The liquid flowing onto the inner wall of the tower body 1 flows and falls under the action of gravity.

[0044] When passing through the guide ring 25, the liquid flows down along the top surface and side wall of the guide ring 25 into the guide groove 8 of the rotating frame 7. The liquid accumulates in the guide groove 8 and flows along the guide groove 8 towards the center of the rotating frame 7. The liquid flows to the liquid outlet 9 and falls from the liquid outlet 9. At the same time, the rotating frame 7 rotates, changing the horizontal position of the liquid outlet 9 and increasing the size of the distribution area of ​​the liquid flowing out of the liquid outlet 9 on the plane. This allows the liquid flow on the inner wall of the tower body 1 to be redistributed to fall near the center of the tower body 1, so that the liquid can effectively contact the exhaust gas and improve the utilization efficiency of the sprayed liquid. At the same time, the redistributed liquid can fall to the bottom packing layer at various positions in the radial and circumferential directions. Compared with the wall flow contacting the edge of the packing layer, it improves the uniformity of the redistributed liquid contact distribution with the packing layer, ensuring that the liquid forming the wall flow can participate in the flow on the surface of the packing in the packing layer and ensure the overall purification efficiency.

[0045] When the wall flow of tower body 1 is low, the liquid flow on the guide channel 8 is exhausted when it flows through the liquid outlet 9 near the outer side of tower body 1, resulting in less or no liquid flow to the liquid outlet 9 located on the inner side.

[0046] Example 2, as Figures 1-9 Based on Embodiment 1, a plurality of movable plates 20 for sealing the liquid outlet holes 9 are slidably disposed at the bottom of the inner wall of the guide channel 8. The movable plates 20 are arranged radially and can slide relative to the rotating frame 7 in the radial direction. The top surface of the movable plates 20 is flush with the bottom surface of the inner wall of the guide channel 8. The body of the movable plates 20 has a plurality of connecting holes 21, which are arranged at uniform intervals. The number of connecting holes 21 is adapted to the number of liquid outlet holes 9 sealed by the corresponding movable plates 20. (See reference...) Figure 8 An adjusting spring 24 is fixedly connected to one side of the movable plate 20.

[0047] Adjusting spring 24 is used to push movable plate 20 toward the rotation center of rotating frame 7, so that the position of connecting hole 21 is offset from the horizontal position of liquid outlet hole 9. When adjusting spring 24 is in the contracted state, the position of connecting hole 21 corresponds to the position of liquid outlet hole 9, so that connecting hole 21 connects guide groove 8 and liquid outlet hole 9. (See reference) Figure 9 An adjusting plate 19 is fixedly installed at the bottom of the rotating seat 18. (See reference) Figure 10 The outer wall of the adjusting plate 19 has a wave-like shape, which causes the distance between the outer wall of the adjusting plate 19 and the axis of the drive shaft 11 to change back and forth. A connecting rod 22 is fixedly connected to one side of the movable plate 20. An adjusting wheel 23 is rotatably set on one side of the bottom of the connecting rod 22. The adjusting wheel 23 is used to abut against the side wall of the adjusting plate 19 in a rolling contact manner. Among the liquid outlet holes 9 corresponding to a single rotating frame 7, the distance from different liquid outlet holes 9 to the center of the rotating frame 7 is different, so that the rotation radius corresponding to different liquid outlet holes 9 is different.

[0048] During the rotation of the rotating frame 7, the rotation of the rotating frame 7 drives the movable plate 20 to rotate around the axis of the transmission shaft 11. The movable plate 20 drives the connecting rod 22 to rotate. The adjusting spring 24 pushes the movable plate 20. With the help of the connecting rod 22, the adjusting wheel 23 is kept in contact with the outer wall of the adjusting plate 19. At the same time, the connecting rod 22 drives the adjusting wheel 23 to rotate along the adjusting plate 19, so that the distance from the adjusting wheel 23 to the axis of the transmission shaft 11 increases and decreases back and forth with the rotation, changing alternately. With the help of the elastic force of the adjusting spring 24, the adjusting wheel 23 drives the connecting rod 22 to move back and forth in the radial direction of the rotating frame 7. The connecting rod 22 drives the movable plate 20 to move back and forth.

[0049] When the movable plate 20 approaches the regulating plate 19, the movable plate 20 moves the position of the connecting hole 21 away from the top of the liquid outlet 9, and the movable plate 20 keeps the liquid outlet 9 closed. At this time, the wall flow falls into the guide groove 8 and accumulates in the guide groove 8, so that liquid accumulates in the guide groove 8 at the top of several liquid outlets 9. When the movable plate 20 moves relatively away from the regulating plate 19, the position of the connecting hole 21 moves to correspond to the position of the liquid outlet 9. The liquid in the guide groove 8 flows out of the liquid outlet 9 through the connecting hole 21 while the rotating frame 7 rotates, completing the redistribution after the wall flow is collected. This avoids the packing layer receiving the wall flow from the liquid outlet 9 and concentrating it on the outside, further improving the uniformity of the redistribution of the wall flow in the liquid outlet 9. With the different rotation radii corresponding to different liquid outlets 9, the uniformity of the radial distribution of the liquid flow discharged from the liquid outlet 9 can be improved when the wall flow is small.

[0050] Example 3, as Figures 1-10 Based on Embodiment 1, a limiting rod 27 is slidably sleeved on the inner side of the drive shaft 11. The top surface of the limiting rod 27 communicates with the cavity of the fixed cylinder 10. The cross-section of the limiting rod 27 is T-shaped, allowing it to slide axially without disengaging from the drive shaft 11. A return spring 28 is movably sleeved on one end of the limiting rod 27. The return spring 28 is used to push the limiting rod 27 out of the drive shaft 11. The water pressure inside the fixed cylinder 10 acts on the top surface of the limiting rod 27, and the elastic force of the return spring 28 acts on the bottom surface of the wide part of the limiting rod 27. A through hole is opened on one side of the top of the drive shaft 11 to allow for pressure changes within the movable cavity at the bottom of the limiting rod 27. A limiting block 29 is fixedly sleeved on the rod of the limiting rod 27. The number of limiting blocks 29 matches the number of rotating frames 7. (See reference...) Figure 9 A movable rod 31 is fixedly connected to one side of the connecting rod 22. A fixed block 30 is slidably sleeved on the outer side of the movable rod 31. The fixed block 30 is fixedly connected to the transmission shaft 11.

[0051] When the purification equipment needs to process a large amount of waste gas in a short time, the amount of liquid pumped into the inlet pipe 16 is increased so that the amount of liquid sprayed out by the spray assembly 4 of the purification equipment remains at a high flow rate. At this time, the liquid pressure in the fixed cylinder 10 increases, and the liquid flow rate along the tower wall also increases. The rotating frame 7 continues to rotate, and the connecting rod 22 moves back and forth in the radial direction of the rotating frame 7, driving the moving rod 31 to move relative to the fixed block 30. The liquid pressure in the fixed cylinder 10 overcomes the elastic force of the return spring 28 and pushes the limit rod 27 to retract into the drive shaft 11.

[0052] When the connecting rod 22 drives the moving rod 31 away from the drive shaft 11, the moving rod 31 moves horizontally away from the bottom of the limiting block 29. The limiting rod 27 moves, causing the limiting block 29 to move to one end of the moving rod 31. The limiting adjusting spring 24 drives the moving rod 31 to move closer to the drive shaft 11, thereby limiting the moving plate 20 to move closer to the center of the rotating frame 7. The connecting hole 21 and the liquid outlet hole 9 always maintain a corresponding state, so that the opening of the liquid outlet hole 9 is kept at its maximum. Under the condition of high flow rate, the wall flow into the guide channel 8 is discharged through each liquid outlet hole 9, so that the average opening of the liquid outlet hole 9 increases over a period of time to meet the increased wall flow rate, avoiding the liquid outlet hole 9 opening being too small, causing liquid to accumulate in the guide channel 8 and overflow from the top, further improving the reliability and adaptability of the purification equipment.

[0053] The exhaust gas purification process of the automotive anti-vibration expansion rubber production line includes the following steps:

[0054] S1: The exhaust gas is introduced from the bottom of the tower body 1 and liquid is supplied into the spray assembly 4 so that the spray assembly 4 sprays liquid for purifying the exhaust gas from the bottom of the tower body 1.

[0055] S2: The drive mechanism drives the transmission shaft 11 to rotate, and the transmission shaft 11 drives the corresponding rotating frame 7 to rotate. At the same time, the liquid flow on the inner wall of the tower body 1 falls into the guide groove 8 through the outer wall of the guide ring 25.

[0056] S3: The liquid flows along the guide groove 8 toward the center of the rotating frame 7. When the liquid flows through the outlet hole 9, it is discharged from the outlet hole 9. At the same time, the rotating frame 7 rotates to change the horizontal position of the outlet hole 9, so that the liquid discharged from the outlet hole 9 falls in the horizontal plane along the corresponding annular distribution.

[0057] S4: During the process of the exhaust gas passing through the chamber of tower body 1, it comes into contact with the liquid on the surface of the packing after passing through the liquid outlet 9 and the liquid distribution of the spray assembly 4, and the exhaust gas comes into contact with the liquid discharged from the liquid outlet 9 and the liquid output of the spray assembly 4, thus purifying the exhaust gas.

[0058] S5: The purified gas is discharged from the top of tower 1 after being demisted, and the liquid used for purification is recovered from the bottom of tower 1.

[0059] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
