Energy-saving chemical machinery tail gas treatment structure

Abstract

The invention relates to the technical field of tail gas treatment, and discloses an energy-saving chemical machinery tail gas treatment structure which is fixedly connected to a plurality of telescopic collecting boxes on the outer wall of the bottom of an outer air duct, and first springs are fixedly connected to the outer walls of the telescopic collecting boxes. Two bottom plates are fixedly connected to the ends, away from the telescopic collecting box, of the first springs, and connecting shafts are rotationally connected to the inner walls of the two bottom plates. The outer wall of the connecting shaft is rotationally connected with the inner wall of the telescopic collecting box. Due to the fact that the telescopic collecting box can stretch out and draw back at will along with the internal weight, when solid waste in the telescopic collecting box is accumulated to a certain degree, the telescopic collecting box can drive the two bottom plates to stretch out to the position of the limiting rod, and when the accumulated weight is larger than the elastic force applied by the first spring to the two bottom plates, the two bottom plates can be opened from the middle, and the solid waste can be collected. And solid waste accumulated in the telescopic collecting box can fall into the shell and then is discharged out of the device.

Description

Technical Field

[0001] The present invention relates to the technical field of tail gas treatment equipment, and specifically to an energy-saving chemical machinery tail gas treatment structure. Background Art

[0002] Currently, the existing technology of chemical machinery tail gas treatment devices mainly relies on the spraying method of tail gas treatment liquid. In this technology, the treatment liquid is evenly sprayed into the tail gas emission stream through a specific spraying device, aiming to capture and remove harmful components in the tail gas through chemical reactions or physical adsorption.

[0003] Among them, since solid waste and small particulate solid matter are generated in the tail gas produced by chemical machinery, and the slightly larger solid waste will enter the tail gas treatment device under the drive of the tail gas. When using treatment equipment in the form of a filter screen, problems such as filter screen clogging and difficulty in cleaning will occur, resulting in a reduction in the efficiency of treating tail gas. In response to the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an energy-saving chemical machinery tail gas treatment structure, which includes a plurality of support columns. At the outer wall of the top of the plurality of support columns, a housing is fixedly connected. It further includes:

[0005] A fixing mechanism, which is fixedly connected to the inner wall of the housing;

[0006] A limiting mechanism, which is fixedly connected to the inner wall of the housing;

[0007] A cleaning mechanism, which is fixedly connected to the outer wall of the limiting mechanism;

[0008] When the limiting mechanism moves, it will drive the cleaning mechanism to move, thereby cleaning the fixing mechanism;

[0009] Preferably, the fixing mechanism includes: a fixing component, which is fixedly connected to the inner wall of the housing; a collecting component, which is fixedly connected to the outer wall of the fixing component through a fixing part. The fixing part includes a limiting rod fixedly connected to the outer wall of the fixing component.

[0010] Preferably, the limiting mechanism includes: a limiting component, which is fixedly connected to the inner wall of the housing through a connecting part. The connecting part includes a fixing rod fixedly connected to the inner wall of the inner cavity. Two connecting rods are rotatably connected to the inner wall of the central axis of the fixing rod; a releasing component, which is rotatably connected to the limiting component through a rotating part. The rotating part includes an excitation rod rotatably connected to the inner walls of the two connecting rods.

[0011] Preferably, the cleaning mechanism includes: a cleaning component, whose outer wall is fixedly connected to the bottom inner wall of the limiting component; a recycling mechanism, whose outer wall is fixedly connected to the inner wall of the housing.

[0012] Preferably, the fixing component includes an outer air duct fixedly connected to the inner wall of the housing. A plurality of acoustic agglomeration systems are fixedly connected to the outer wall of the outer air duct. An inner air duct is fixedly connected to the outer wall of the outer air duct. A cavity is fixedly connected to the outer wall of the inner air duct.

[0013] Since a plurality of acoustic agglomeration systems are provided between the outer air duct and the cavity, when the tail gas carrying solid particles enters, the acoustic agglomeration systems will agglomerate the small particle solid particles together, reducing the concentration of small particle solid particles in the tail gas. When the agglomerated solid particles and the tail gas enter the interior of the cavity through the inner air duct, the spray pipe will release the adsorbent to mix and adsorb the solid particles in the tail gas. Since the weight of the mixture after adsorption is relatively large, it is difficult for the tail gas to blow the mixture away. As a result, the mixture will fall to the bottom of the cavity and be discharged.

[0014] Preferably, the collection component includes a plurality of telescopic collection boxes fixedly connected to the outer wall of the bottom of the outer air duct. A first spring is fixedly connected to the outer wall of the plurality of telescopic collection boxes. One end of the first spring away from the telescopic collection box is fixedly connected to two bottom plates. A connecting shaft is rotatably connected to the inner walls of the two bottom plates; the outer wall of the connecting shaft is rotatably connected to the inner wall of the telescopic collection box.

[0015] When it is necessary to process the tail gas generated by chemical machinery, the tail gas output by the chemical machinery is input into the outer air duct. When the tail gas carrying solids enters the outer air duct, since the outer air duct is a spiral rising pipe, when relatively large solid waste enters the interior of the outer air duct, due to its own relatively large weight, the solid waste will enter the interior of the telescopic collection box in the collection component. At this time, the relatively large solid waste can be concentrated in the telescopic collection box; since the telescopic collection box can expand and contract freely according to the weight inside, when the solid waste in the telescopic collection box accumulates to a certain extent, the telescopic collection box will extend with the two bottom plates to the position of the limiting rod. When the accumulated weight is greater than the elastic force exerted by the first spring on the two bottom plates, the two bottom plates will open from the middle, causing the solid waste accumulated in the telescopic collection box to fall into the interior of the housing and then be discharged from the device.

[0016] Preferably, the limiting component includes a connecting rod rotatably connected to the inner wall of the end of the excitation rod away from it. A second spring is fixedly connected to the outer wall of the bottom of the connecting rod. One end of the second spring away from the connecting rod is fixedly connected to a piston. Two one-way plates are rotatably connected to the inner wall of the piston.

[0017] When the exhaust gas inside the inner cavity is released, the pressure inside the inner cavity will gradually decrease. At this time, as the pressure inside the inner cavity gradually decreases, the piston will gradually descend. At this time, the scraping strip connected by the connecting column will descend with the piston and can clean the inner wall downward. When the piston moves downward to a certain position, the piston will pull the second spring. At this time, the excitation rod is restricted by the third spring and the limiting ball and cannot move upward. Therefore, the excitation rod will continue to restrict the closing of the one-way plate, so that during the downward movement of the piston, the one-way plate will gradually close. When the piston descends to a certain extent, the elastic force received by the second spring is greater than the elastic force of the third spring on the limiting ball, and the excitation rod will break through the restriction of the third spring and the limiting ball and thus continue to move upward;

[0018] Preferably, the release assembly includes a sleeve fixedly connected to the inner wall of the fixed rod. Two third springs are fixedly connected to the inner wall of the sleeve. The two third springs are fixedly connected with a limiting ball at the end far from the inner wall of the sleeve. The outer wall of the excitation rod is slidably connected to the sleeve.

[0019] Since two third springs are fixedly connected to the inner wall of the sleeve and the third springs are fixedly connected with a limiting ball at the end far from the inner wall of the sleeve, when the protrusion on the excitation rod moves to the outer wall of the limiting ball, the protrusion on the excitation rod will squeeze the limiting ball. Due to the existence of the third spring, when the limiting ball is squeezed, the third spring will also be squeezed. At this time, the third spring will gradually accumulate elastic force. Since the movement of the excitation rod is restricted, the second spring will also be squeezed. When the piston continues to move to the limit position, at this time, the elastic force of the third spring is less than the elastic force accumulated by the second spring, and the excitation rod will break through the restriction of the third spring and the limiting ball and suddenly move downward. At this time, the piston moves to the limit position, so the excitation rod will strike one end of the one-way plate rotatably connected to the inner wall of the piston, causing the one-way plate to open downward. At this time, the treated exhaust gas accumulated inside the inner cavity will pass through the one-way plate;

[0020] When the piston moves upward, the piston will squeeze the second spring. Since the top of the second spring is fixedly connected with a connecting rod, the top of the connecting rod is rotatably connected with a connecting rod, and the end of the connecting rod far from the connecting rod is rotatably connected with an excitation rod. The central axis of the connecting rod is rotatably connected to the inner wall of the fixed rod. Therefore, when the elastic force of the second spring acts on the connecting rod and makes the connecting rod move upward, through the action of the connecting rod, the excitation rod moves. Due to the existence of the sleeve, the excitation rod will move downward;

[0021] Preferably, the cleaning component includes a connecting column fixedly connected to the inner wall of the bottom of the piston. A scraping strip is fixedly connected to the outer wall of the bottom of the connecting column. A spray pipe is fixedly connected to the inner wall of the top of the housing. When the tail gas enters the inner cavity, due to the presence of the piston and the one-way plate, the pressure between the lower part of the piston and the inner wall of the inner cavity will increase. When the pressure gradually increases, the piston will move upward. Since a connecting column is fixedly connected to the outer wall of the bottom of the piston and a scraping strip is fixedly connected to the outer wall of the bottom of the connecting column, when the piston moves upward, the scraping strip will be driven to move, so that the scraping strip can clean the inner wall of the inner cavity upward;

[0022] Preferably, the recycling mechanism includes an air outlet pipe fixedly connected to the inner wall of the top of the housing. A conical air inlet sleeve is fixedly connected to the outer wall of the bottom of the air outlet pipe. A plurality of filter meshes are fixedly connected to the inner wall of the air outlet pipe. A reflux pipe is fixedly connected to the outer wall of the air outlet pipe.

[0023] When the processed tail gas reaches the conical air inlet sleeve through the one-way plate, since a plurality of filter meshes are arranged on the inner wall of the air outlet pipe, when passing through the U-shaped part of the air outlet pipe, a small part of the mixture or adsorbent carried by the tail gas will be blocked by the filter meshes and enter the reflux pipe, flow back into the device, and be discharged out of the device together with other mixtures.

[0024] The present invention has the following beneficial effects:

[0025] (1) In the present invention, a solid waste collection device is arranged at the air duct inside the device. When the tail gas carries solid waste into the device, due to the large weight of the solid waste, it will first contact the turning point of the air duct, and at this time the solid waste will enter the collection device. Compared with the filter-type filtering equipment, while effectively preventing solid substances from entering the device, the influence of blockage on the device is reduced;

[0026] (2) In the present invention, an automatic cleaning mechanism is arranged in the collection device. When the solid waste in the collection device is collected to a certain weight, the cleaning mechanism will be triggered to perform automatic cleaning to prevent the solid waste in the collection device from overflowing due to excessive amount and entering the device along with the tail gas;

[0027] (3) In the present invention, a scraper is arranged inside the device. When a mixture of solid particles and adsorption liquid accumulates on the inner wall of the device, the scraper can clean the inner wall along with the change of air pressure in the inner wall device;

[0028] (4) In the present invention, a filter mesh and a recycling component are arranged inside the air outlet pipe, which can collect and recycle the mixture carried out by the tail gas into the device and perform separation and cleaning again, so that the concentration of solid particles and mixture in the tail gas is reduced.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] Example 1, please refer to Figures 1-5 , the present invention is an energy-saving chemical machinery tail gas treatment structure, including a plurality of support columns 13, and a housing 14 is fixedly connected to the outer wall of the tops of the plurality of support columns 13. It is characterized in that it further includes:

[0044] Fixing mechanism 1, which is fixedly connected to the inner wall of the housing 14;

[0045] Limiting mechanism 2, which is fixedly connected to the inner wall of the housing 14;

[0046] Cleaning mechanism 3, which is fixedly connected to the outer wall of the limiting mechanism 2;

[0047] When the limiting mechanism 2 moves, it will drive the cleaning mechanism 3 to move, so as to clean the fixing mechanism 1;

[0048] The fixing mechanism 1 includes: a fixing component 11, which is fixedly connected to the inner wall of the housing 14; a collection component 12, which is fixedly connected to the outer wall of the fixing component 11 through a fixing member; the fixing member includes a limiting rod 125 fixedly connected to the outer wall of the fixing component 11.

[0049] The limiting mechanism 2 includes: a limiting component 21, the limiting component 21 is fixedly connected to the inner wall of the outer shell 14 through a connecting piece; the connecting piece includes a fixing rod 211 fixedly connected to the inner wall of the inner cavity 114, and two connecting rods 212 are rotatably connected to the inner wall of the central axis of the fixing rod 211; a release component 22, the release component 22 is rotatably connected to the limiting component 21 through a rotating piece; the rotating piece includes an excitation rod 221 rotatably connected to the inner walls of the two connecting rods 212.

[0050] The cleaning mechanism 3 includes: a cleaning component 31, the outer wall of the cleaning component 31 is fixedly connected to the bottom inner wall of the limiting component 21; a recycling mechanism 32, the outer wall of the recycling mechanism 32 is fixedly connected to the inner wall of the outer shell 14.

[0051] The fixing component 11 includes an outer air duct 111 fixedly connected to the inner wall of the outer shell 14, several acoustic agglomeration systems 112 are fixedly connected to the outer wall of the outer air duct 111, an inner air duct 113 is fixedly connected to the outer wall of the outer air duct 111, and an inner cavity 114 is fixedly connected to the outer wall of the inner air duct 113.

[0052] The collection component 12 includes several telescopic collection boxes 121 fixedly connected to the bottom outer wall of the outer air duct 111, a first spring 122 is fixedly connected to the outer walls of the several telescopic collection boxes 121, one end of the first spring 122 away from the telescopic collection box 121 is fixedly connected to two bottom plates 123, and a connecting shaft 124 is rotatably connected to the inner walls of the two bottom plates 123; the outer wall of the connecting shaft 124 is rotatably connected to the inner wall of the telescopic collection box 121.

[0053] During use, first set the entire device in a suitable position. When it is necessary to process the tail gas generated by chemical machinery, input the tail gas output by the chemical machinery into the outer air duct 111. When the tail gas carries solids into the outer air duct 111, since the outer air duct 111 is a spiral ascending pipe, when relatively large solid waste enters the interior of the outer air duct 111, due to its relatively large own weight, the solid waste will enter the interior of the telescopic collection box 121 in the collection component 12. At this time, the relatively large solid waste can be concentrated in the telescopic collection box 121; since the telescopic collection box 121 can expand and contract freely according to the weight inside, when the solid waste in the telescopic collection box 121 accumulates to a certain extent, the telescopic collection box 121 will extend with the two bottom plates 123 to the position of the limiting rod 125. When the accumulated weight is greater than the elastic force exerted by the first spring 122 on the two bottom plates 123, the two bottom plates 123 will open from the middle, so that the solid waste accumulated in the telescopic collection box 121 will fall into the interior of the outer shell 14 and then be discharged from the device;

[0054] Example two, please refer to Figures 1-10, based on Example 1 of the present invention which is an energy-saving chemical machinery tail gas treatment structure, the limiting component 21 includes a connecting rod 213 rotatably connected to the inner wall of one end of the connecting rod 212 away from the excitation rod 221. A second spring 214 is fixedly connected to the outer wall of the bottom of the connecting rod 213. One end of the second spring 214 away from the connecting rod 213 is fixedly connected to a piston 215. Two one-way plates 216 are rotatably connected to the inner wall of the piston 215.

[0055] The release component 22 includes a sleeve 222 fixedly connected to the inner wall of the fixed rod 211. Two third springs 223 are fixedly connected to the inner wall of the sleeve 222. One end of the two third springs 223 away from the inner wall of the sleeve 222 is fixedly connected to a limiting ball 224; the outer wall of the excitation rod 221 is slidably connected to the sleeve 222.

[0056] The cleaning component 31 includes a connecting column 311 fixedly connected to the inner wall of the bottom of the piston 215. A scraping strip 313 is fixedly connected to the outer wall of the bottom of the connecting column 311. A spray pipe 312 is fixedly connected to the inner wall of the top of the housing 14.

[0057] The recovery mechanism 32 includes an air outlet pipe 321 fixedly connected to the inner wall of the top of the housing 14. A conical air inlet sleeve 322 is fixedly connected to the outer wall of the bottom of the air outlet pipe 321. A plurality of filter meshes 323 are fixedly connected to the inner wall of the air outlet pipe 321. A return pipe 324 is fixedly connected to the outer wall of the air outlet pipe 321.

[0058] Since a plurality of acoustic agglomeration systems 112 are provided between the outer air duct 111 and the inner cavity 114, when the tail gas carries solid particles into it, the acoustic agglomeration systems 112 will agglomerate the small particle solid particles together, reducing the concentration of small particle solid particles in the tail gas. When the agglomerated solid particles and the tail gas enter the interior of the inner cavity 114 through the inner air duct 113, the spray pipe 312 will release an adsorbent to mix and adsorb the solid particles in the tail gas. Since the weight of the mixture after adsorption is relatively large, it is difficult for the tail gas to blow the mixture away, so the mixture will fall to the bottom of the inner cavity 114 and be discharged;

[0059] When the tail gas enters the interior of the inner cavity 114, due to the presence of the piston 215 and the one-way plates 216, the pressure between the lower part of the piston 215 and the inner wall of the inner cavity 114 will increase. When the pressure gradually increases, the piston 215 will move upward. Since a connecting column 311 is fixedly connected to the outer wall of the bottom of the piston 215 and a scraping strip 313 is fixedly connected to the outer wall of the bottom of the connecting column 311, when the piston 215 moves upward, it will drive the scraping strip 313 to move, so that the scraping strip 313 can clean the inner wall of the inner cavity 114 upward;

[0060] When the piston 215 moves upward, the piston 215 will squeeze the second spring 214. Since the top of the second spring 214 is fixedly connected to the connecting rod 213, the top of the connecting rod 213 is rotatably connected to the connecting rod 212, and one end of the connecting rod 212 away from the connecting rod 213 is rotatably connected to the actuating rod 221. The middle axis of the connecting rod 212 is rotatably connected to the inner wall of the fixed rod 211. Therefore, when the elastic force of the second spring 214 acts on the connecting rod 213 and causes the connecting rod 213 to move upward, through the action of the connecting rod 212, the actuating rod 221 moves. Due to the existence of the sleeve 222, the actuating rod 221 will move downward;

[0061] Since the third spring 223 is fixedly connected to the inner wall of the sleeve 222, and one end of the third spring 223 away from the inner wall of the sleeve 222 is fixedly connected to the limiting ball 224. Therefore, when the protrusion on the actuating rod 221 moves to the outer wall of the limiting ball 224, the protrusion on the actuating rod 221 will squeeze the limiting ball 224. Due to the existence of the third spring 223, when the limiting ball 224 is squeezed, the third spring 223 will also be squeezed. At this time, the third spring 223 will gradually accumulate elastic force. Since the movement of the actuating rod 221 is restricted, the second spring 214 will also be squeezed. When the piston 215 continues to move to the extreme position, at this time, the elastic force of the third spring 223 is less than the elastic force accumulated by the second spring 214, and the actuating rod 221 will suddenly move downward breaking through the restriction of the third spring 223 and the limiting ball 224. At this time, the piston 215 moves to the extreme position, so the actuating rod 221 will strike one end of the one-way plate 216 rotatably connected to the inner wall of the piston 215, causing the one-way plate 216 to open downward. At this time, the treated exhaust gas accumulated inside the inner cavity 114 will pass through the one-way plate 216;

[0062] After the exhaust gas inside the inner cavity 114 is released, the pressure inside the inner cavity 114 will gradually be released. At this time, since the pressure inside the inner cavity 114 gradually decreases, the piston 215 will gradually descend. At this time, the scraping strip 313 connected by the connecting column 311 will descend with the piston 215 and can clean the inner wall of 114 downward. When the piston 215 moves downward to a certain position, the piston 215 will pull the second spring 214. At this time, the actuating rod 221 is restricted by the third spring 223 and the limiting ball 224 and cannot move upward. Therefore, the actuating rod 221 will continue to restrict the closing of the one-way plate 216, so that during the descent of the piston 215, the one-way plate 216 will gradually close. When the piston 215 descends to a certain extent, the elastic force received by the second spring 214 is greater than the elastic force of the third spring 223 on the limiting ball 224, and the actuating rod 221 will break through the restriction of the third spring 223 and the limiting ball 224 and thus continue to move upward;

[0063] When the treated tail gas reaches the conical air inlet sleeve 322 through the one-way plate 216, since a number of filter meshes 323 are provided at the inner wall of the air outlet pipe 321, when passing through the U-shaped part of the air outlet pipe 321, a small part of the mixture or adsorbent carried by the tail gas will be blocked by the filter meshes 323 and enter the return pipe 324, flow back into the device, and be discharged out of the device together with other mixtures.

[0064] A specific application of this embodiment is as follows: During use, first set the entire device in a suitable position. When it is necessary to treat the tail gas generated by chemical machinery, input the tail gas output by the chemical machinery into the outer air duct 111. When the tail gas carries solid substances into the outer air duct 111, since the outer air duct 111 is a spiral rising pipe, when relatively large solid waste enters the interior of the outer air duct 111, due to its relatively large own weight, the solid waste will enter the telescopic collection box 121 inside the collection assembly 12. At this time, the relatively large solid waste can be concentrated in the telescopic collection box 121; since the telescopic collection box 121 can expand and contract freely according to the weight inside, when the solid waste in the telescopic collection box 121 accumulates to a certain extent, the telescopic collection box 121 will extend with two bottom plates 123 to the position of the limit rod 125. When the accumulated weight is greater than the elastic force exerted by the first spring 122 on the two bottom plates 123, the two bottom plates 123 will open from the middle, so that the solid waste accumulated in the telescopic collection box 121 will fall into the interior of the outer shell 14 and then be discharged from the device;

[0065] Since a number of acoustic agglomeration systems 112 are provided between the outer air duct 111 and the inner cavity 114, when the tail gas carries solid particulate matter and enters, the acoustic agglomeration systems 112 will agglomerate the small particulate solid matter therein, reducing the concentration of small particulate solid matter in the tail gas. When the agglomerated solid particulate matter and the tail gas enter the interior of the inner cavity 114 through the inner air duct 113, the spray pipe 312 will release the adsorbent to mix and adsorb the solid particulate matter in the tail gas. Since the weight of the mixture after adsorption is relatively large, it is difficult for the tail gas to drive the mixture to continue moving, so the mixture will fall to the bottom of the inner cavity 114 and then be discharged;

[0066] When the tail gas enters the interior of the inner cavity 114, due to the presence of the piston 215 and the one-way plate 216, the pressure below the piston 215 and the inner wall of the inner cavity 114 will increase. When the pressure gradually increases, the piston 215 will move upward. Since a connecting column 311 is fixedly connected to the bottom outer wall of the piston 215, and a scraping strip 313 is fixedly connected to the bottom outer wall of the connecting column 311, when the piston 215 moves upward, it will drive the scraping strip 313 to move, so that the scraping strip 313 can clean the inner wall of the inner cavity 114 upward.

[0067] When the piston 215 moves upward, the piston 215 will squeeze the second spring 214. Since the top of the second spring 214 is fixedly connected to the connecting rod 213, the top of the connecting rod 213 is rotatably connected to the connecting rod 212. One end of the connecting rod 212 away from the connecting rod 213 is rotatably connected to the actuating rod 221. The middle axis of the connecting rod 212 is rotatably connected to the inner wall of the fixed rod 211. Therefore, when the elastic force of the second spring 214 acts on the connecting rod 213 and causes the connecting rod 213 to move upward, through the action of the connecting rod 212, the actuating rod 221 moves. Due to the existence of the sleeve 222, the actuating rod 221 will move downward;

[0068] Since the third spring 223 is fixedly connected to the inner wall of the sleeve 222, and one end of the third spring 223 away from the inner wall of the sleeve 222 is fixedly connected to the limiting ball 224. Therefore, when the protrusion on the actuating rod 221 moves to the outer wall of the limiting ball 224, the protrusion on the actuating rod 221 will squeeze the limiting ball 224. Due to the existence of the third spring 223, when the limiting ball 224 is squeezed, the third spring 223 will also be squeezed. At this time, the third spring 223 will gradually accumulate elastic force. Since the movement of the actuating rod 221 is restricted, the second spring 214 will also be squeezed. When the piston 215 continues to move to the extreme position, at this time, the elastic force of the third spring 223 is less than the elastic force accumulated by the second spring 214, and the actuating rod 221 will suddenly move downward breaking through the restriction of the third spring 223 and the limiting ball 224. At this time, the piston 215 moves to the extreme position, so the actuating rod 221 will strike one end of the one-way plate 216 rotatably connected to the inner wall of the piston 215, causing the one-way plate 216 to open downward. At this time, the treated tail gas accumulated inside the inner cavity 114 will pass through the one-way plate 216;

[0069] After the tail gas inside the inner cavity 114 is released, the pressure inside the inner cavity 114 will gradually be released. At this time, since the pressure inside the inner cavity 114 gradually decreases, the piston 215 will gradually descend. At this time, the scraping strip 313 connected by the connecting column 311 will descend along with the piston 215, and can clean the inner wall of 114 downward. When the piston 215 moves downward to a certain position, the piston 215 will pull the second spring 214. At this time, the actuating rod 221 is restricted by the third spring 223 and the limiting ball 224 and cannot move upward. Therefore, the actuating rod 221 will continue to restrict the closing of the one-way plate 216, so that during the descent of the piston 215, the one-way plate 216 will gradually close. When the piston 215 descends to a certain extent, the elastic force received by the second spring 214 is greater than the elastic force of the third spring 223 on the limiting ball 224, and the actuating rod 221 will break through the restriction of the third spring 223 and the limiting ball 224 and thus continue to move upward;

[0070] When the processed tail gas reaches the conical air inlet sleeve 322 through the one-way plate 216, since a plurality of filter screens 323 are provided at the inner wall of the air outlet pipe 321, when passing through the U-shaped part of the air outlet pipe 321, a small part of the mixture or adsorbent carried by the tail gas will be blocked by the filter screens 323 and enter the reflux pipe 324, flow back into the device, and be discharged out of the device together with other mixtures.
