However, there are still some problems with existing waste gas treatment devices:

The condensate recovery device includes a housing with a bottom straight cylinder at the bottom of the housing; a curved exhaust pipe is installed in the middle of the side wall of the housing; a cover plate is fixed to the top flange, and a medium box is installed on the cover plate. Two medium flow channels are provided in the medium box, and a medium outlet pipe and a medium inlet pipe are provided at the top of the medium box.

[0004] An activated carbon waste gas treatment device and control method with announcement number CN118577094A includes a housing, several mounting brackets, several first adsorption modules, several second adsorption modules and several flipping mechanisms. A filter chamber is provided inside the housing, and an air inlet and an air outlet are provided on the side of the housing. Several mounting brackets are provided in the filter chamber, and a first adsorption module and a second adsorption module are fixedly mounted on each mounting bracket.

[0021] The operation method of the chemical waste gas treatment device includes the following steps:

[0022] S1: Connect the external exhaust gas pipe and the air pipe in the middle of the shell, and the exhaust gas will enter the shell. Then the device system controls the first electric cylinder to start. The first electric cylinder will push the moving cover and the loading plug cylinder to move downward synchronously through the connecting cylinder. The loading plug cylinder will drive the inner core cylinder and the loading cylinder to move synchronously. At this time, the moving cover will push the outer filter ring to move downward, and the outer filter ring will push the lifting ring to move synchronously. The locking rod on the lifting ring moves toward the locking hole, and the lifting ring further compresses the pressure spring. When the air holes on the outer filter ring and the air holes on the inner filter ring are aligned and connected, the locking rod will face the locking hole. At this time, the thrust spring will drive the locking rod to move through the reset effect, so that the locking rod enters the locking hole to form a locking structure. The control frame installed on the end of the locking rod moves synchronously, and the control frame will slide on the sliding plate. At the same time, the sliding plate will move accordingly on the base. At this time, the outer filter ring will be positioned;

[0023] S2: In the process of the movable cover and the loading plug barrel moving downward synchronously, since the air holes on the outer filter ring and the air holes on the inner filter ring are first in a dislocated and closed state, the air pressure between the movable cover and the base will increase. At this time, the gas in the movable cover will enter the connecting barrel through the lower exhaust duct and the lower docking port, and the gas in the connecting barrel will enter the adsorption block through the air exchange port and the air vent on the inner core barrel. The adsorption block is made of activated carbon material and is used to adsorb harmful components in the gas. The gas enters the air pressure cylinder after passing through the adsorption holes on the adsorption block. In the process of the loading plug barrel moving downward, the air pressure in the air pressure cylinder will drop synchronously, so that the gas can fully pass through the adsorption block to improve the adsorption efficiency. When the loading cylinder drives the one-way teeth away from the air pressure cylinder, the reset spring will push the guide plate and the one-way teeth to move through the reset action, so that the one-way teeth extend from the side wall of the loading cylinder, and at the same time, the guide plate drives the connecting rod to disengage from the socket on the limit plate;

[0024] S3: When the movable cover moves to the lowest point, the device controls the first electric cylinder to drive the connecting tube to move upward along the inner wall of the loading tube. The lower docking port of the connecting tube is no longer connected to the lower exhaust duct, while the upper docking port of the connecting tube is connected to the upper exhaust duct. At this time, the connecting tube will move upward and contact the bottom surface of the force ring. The force ring will drive the loading tube to move upward synchronously. The loading tube drives the one-way teeth to contact the port of the air pressure cylinder. The inclined surface of the one-way teeth will move under force, so that the one-way teeth will re-enter the loading tube. At the same time, the guide plate will compress the reset spring, and the end of the plug rod can enter the groove on the limit plate.

[0025] S4: The loading cylinder moving upward will drive the loading plug cylinder and the movable cover to move upward through the inner core cylinder, and the movable cover pulls the rubber belt at the bottom to move. Since the lower exhaust duct on the movable cover is blocked, and the air holes on the inner filter ring are connected to the air holes on the outer filter ring, negative pressure will be generated in the movable cover at this time. At this time, the exhaust gas in the outer shell will flow into the movable cover after being filtered by the inner filter ring and the outer filter ring. At the same time, the loading plug cylinder drives the adsorption block to move upward along the inner wall of the air pressure cylinder to squeeze the gas. At this time, the gas in the air pressure cylinder that has been adsorbed for the first time will pass through the other side of the adsorption block again, and then the gas adsorbed for the second time by the adsorption block will enter the connecting cylinder through the vent and ventilation port of the inner core cylinder, and the gas in the connecting cylinder will enter the exhaust cylinder through the upper docking port and the upper exhaust duct, thereby realizing efficient adsorption on both sides of the adsorption block, and the gas in the exhaust cylinder will enter the subsequent processing equipment;

[0026] S5: When the loading plug cylinder rises to the highest position, the loading cylinder will drive the one-way teeth to align with the slot. At this time, the reset spring will push the guide plate and the one-way teeth to move again, so that the one-way teeth enter the slot. At this time, the loading cylinder will be limited by the one-way teeth. At the same time, the upward moving cover will drive the thrust plate to move synchronously. The inclined surface on the thrust plate will push the force rod to move, and the force rod will drive the control frame to reset. At this time, the control frame will drive the locking rod to disengage from the locking hole, and the locking rod will no longer lock the lifting ring. At this time, the pressure spring can push the lifting ring to move upward and reset through the reset action. The outer filter ring installed on the top of the lifting ring moves synchronously, so that the air holes on the outer filter ring are misaligned with the air holes on the inner filter ring again to form a blocking structure;

[0027] S6: Then the device system will control the first electric cylinder to move downward, and the first electric cylinder will push the connecting tube to move downward, so that the connecting tube is away from the force ring, and the lower docking port at the bottom of the connecting tube will be re-connected with the lower exhaust duct, so that the gas in the movable cover can be pressed into the air pressure cylinder, and the limit plate installed on the side wall of the first electric cylinder moves synchronously so that the socket on the limit plate can be aligned with the plug-in rod. At this time, the device system controls the second electric cylinder to start, and the second electric cylinder will push the arc plate to move synchronously so that the arc plate can push the one-way teeth in the slot to move, and the one-way teeth will move out of the slot. At the same time, the arc surface of the arc plate will be flush with the inner wall of the exhaust tube, and the one-way teeth drive the plug-in rod to move synchronously through the guide plate, so that the plug-in rod can re-enter the socket. At this time, the first electric cylinder can drive the loading tube to move downward through the limit plate and the plug-in rod, thereby performing the next gas processing cycle. When the one-way teeth leave the slot, the second electric cylinder will drive the arc plate to reset.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: the environmentally friendly chemical waste gas treatment device and its use method are provided with an activated carbon adsorption structure capable of bidirectional internal circulation adsorption, so that the gas can flow in two opposite directions within the internal pores of the activated carbon, thereby fully utilizing the adsorption capacity of the activated carbon, while extending the adsorption time and improving the treatment efficiency. The device drives the gas circulation through the air pressure difference, thereby reducing the risk of activated carbon clogging. At the same time, the device can pre-filter impurities in the gas. The specific contents are as follows:

[0029] 1. A bottom surface of a force ring is provided above the connecting tube, and the outer wall of the force ring is coaxially fixedly installed on the inner wall of the loading tube. Upper exhaust ducts with equal angles are provided on the loading tube, and the upper port of the upper exhaust duct faces the inside of the exhaust tube. The lower port of the upper exhaust duct is directly above the upper docking interface. The lower part of the connecting tube slides and fits through the inner core tube and the loading plug tube. The bottom end of the connecting tube is fitly embedded in the top center of the movable cover. Lower exhaust ducts with equal angles are provided on the top of the inner wall of the movable cover, and the lower port of the lower exhaust duct faces the inside of the movable cover. The upper port of the lower exhaust duct is aligned with the lower docking interface for communication, the air exchange port in the middle of the connecting tube is connected to the air vent on the inner core tube, and the upper docking interface on the upper part of the connecting tube is fitly set A closed structure is formed on the inner wall of the loading cylinder. When the movable cover moves downward to squeeze the air, the air in the movable cover passes through the lower exhaust duct, the lower docking port, the connecting cylinder, the ventilation port and the inner core cylinder in sequence, and flows into the air holes of the adsorption block for the first adsorption of harmful components in the gas. The gas will flow into the air pressure cylinder. In the process of the movable cover and the loading plug cylinder moving upward, the position of the connecting cylinder will change, so that the lower docking port of the connecting cylinder will no longer be connected with the lower exhaust duct, and the upper docking port of the connecting cylinder will be connected with the upper exhaust duct. At this time, the loading plug cylinder will squeeze the gas in the air pressure cylinder, so that the gas can flow back into the adsorption block for secondary adsorption. The treated gas will be discharged into the exhaust cylinder through the connecting cylinder, the upper docking port and the upper exhaust duct.

[0030] 2. An inner filter ring and an outer filter ring are slidably inserted in the ring groove at the bottom of the movable cover, and the bottom surface of the inner filter ring is coaxially fixedly mounted on the upper surface of the base, and the outer filter ring is coaxially fitted on the outer wall of the inner filter ring. The bottom of the outer filter ring slides through and is mounted on the top of the base, and the bottom surface of the outer filter ring is coaxially fixedly mounted on the upper surface of the lifting ring. The lifting ring is slidably fitted on the inner wall of the base, and a rubber belt is fixedly connected between the top of the inner filter ring and the inner wall of the movable cover. The air holes on the inner filter ring and the air holes on the outer filter ring are staggered to form a blocking structure, and the top end face of the outer filter ring contacts the inner wall of the movable cover, so that the movable cover can push the inner filter ring to move. At this time, the air holes on the inner filter ring will be connected with the air holes on the outer filter ring to filter the passing gas. At the same time, the moving movable cover can produce a certain cleaning effect on the outer filter ring. BRIEF DESCRIPTION OF THE DRAWINGS

The tooth head of the one-way tooth 3004 is fitted on the inner wall of the top port of the air pressure cylinder 20. The loading cylinder 23 moving downward will drive the one-way tooth 3004 away from the air pressure cylinder 20. At this time, the reset spring 3003 will push the guide plate 3001 and the plug rod 3002 to move synchronously through the reset action, so that the plug rod 3002 is disengaged from the socket 29 on the limit plate 28, so that the first electric cylinder 22 no longer passes through the limit plate 28. 8 drives the loading cylinder 23 to move, and the port at the top of the air pressure cylinder 20 is coaxially fixedly connected to the exhaust cylinder 21, and the lower part of the inner wall of the exhaust cylinder 21 is fitted with the top of the loading cylinder 23, the inner side of the loading cylinder 23 is coaxially provided with the moving end of the first electric cylinder 22, and the top of the first electric cylinder 22 is fixedly connected to the top of the inner wall of the exhaust cylinder 21 by bolts, the bottom of the moving end of the first electric cylinder 22 is coaxially fixedly connected to the connecting cylinder 2601, the bottom surface of the force ring 27 is provided above the connecting cylinder 2601, and the outer wall of the force ring 27 is coaxially fixedly installed on the loading cylinder 23. On the inner wall of the loading cylinder 23, the force ring 27 is coaxially sleeved on the outside of the moving end of the first electric cylinder 22. The loading cylinder 23 is provided with upper exhaust ducts 25 distributed at equal angles, and the upper end of the upper exhaust duct 25 faces the inside of the exhaust cylinder 21, and the lower end of the upper exhaust duct 25 is directly above the upper docking port 2602. When the first electric cylinder 22 drives the connecting cylinder 2601 to move upward, the connecting cylinder 2601 will drive the upper docking port 2602 and the upper exhaust duct 25 to connect. At this time, the gas in the connecting cylinder 2601 can be discharged through the upper exhaust duct 25.

[0055] The operation method of the chemical waste gas treatment device includes the following steps:

[0056] S1: Connect the external exhaust pipe and the air pipe in the middle of the shell 1, and the exhaust gas will enter the shell 1. Then the device system controls the first electric cylinder 22 to start. The first electric cylinder 22 will push the movable cover 15 and the loading plug cylinder 17 to move downward synchronously through the connecting tube 2601. The loading plug cylinder 17 will drive the inner core cylinder 24 and the loading cylinder 23 to move synchronously. At this time, the movable cover 15 will push the outer filter ring 5 downward, and the outer filter ring 5 will push the lifting ring 6 to move synchronously. The locking rod 9 on the lifting ring 6 moves toward the locking hole 11, and the lifting ring 6 further compresses the pressure spring 7. When the air hole on the outer filter ring 5 and the air hole on the inner filter ring 4 are aligned and connected, the locking rod 9 will face the locking hole 11. At this time, the thrust spring 10 will drive the locking rod 9 to move through the reset action, so that the locking rod 9 enters the locking hole 11 to form a locking structure. The control frame 12 installed at the end of the locking rod 9 moves synchronously. The control frame 12 will slide on the sliding plate 35, and the sliding plate 35 will move accordingly on the base 2. At this time, the outer filter ring 5 will be positioned;

[0057] S2: During the synchronous downward movement of the movable cover 15 and the loading plug cylinder 17, since the air holes on the outer filter ring 5 and the air holes on the inner filter ring 4 are first in a dislocated and closed state, the air pressure between the movable cover 15 and the base 2 will increase. At this time, the gas in the movable cover 15 will enter the connecting cylinder 2601 through the lower exhaust duct 34 and the lower docking port 2604, and the gas in the connecting cylinder 2601 will enter the adsorption block 18 through the ventilation port 2603 and the air vent on the inner core cylinder 24. The adsorption block 18 is made of activated carbon material and is used to adsorb harmful components in the gas, and the gas passes through the adsorption block 18. The gas enters the air cylinder 20 through the adsorption hole on the attachment block 18. During the downward movement of the loading plug cylinder 17, the air pressure in the air cylinder 20 will decrease synchronously, allowing the gas to fully pass through the adsorption block 18 to improve the adsorption efficiency. When the loading cylinder 23 drives the one-way teeth 3004 away from the air cylinder 20, the return spring 3003 will push the guide plate 3001 and the one-way teeth 3004 to move through the return action, causing the one-way teeth 3004 to extend from the side wall of the loading cylinder 23. At the same time, the guide plate 3001 drives the plug rod 3002 to disengage from the socket 29 on the limit plate 28.

[0058] S3: When the movable cover 15 moves to the lowest point, the device controls the first electric cylinder 22 to drive the connecting tube 2601 to move upward along the inner wall of the loading tube 23. The lower docking port 2604 of the connecting tube 2601 is no longer connected with the lower exhaust duct 34, and the upper docking port 2602 of the connecting tube 2601 is connected with the upper exhaust duct 25. At this time, the connecting tube 2601 will move upward and contact the bottom surface of the force ring 27. The force ring 27 will drive the loading tube 23 to move upward synchronously. The loading tube 23 drives the one-way teeth 3004 to contact the port of the air pressure tube 20. The inclined surface of the one-way teeth 3004 will be forced to move, so that the one-way teeth 3004 will re-enter the loading tube 23. At the same time, the guide plate 3001 compresses the return spring 3003, and the end of the connecting rod 3002 can enter the groove on the limit plate 28.

[0059] S4: The loading cylinder 23 moving upward will drive the loading plug cylinder 17 and the movable cover 15 to move upward through the inner core cylinder 24. The movable cover 15 pulls the rubber belt 16 at the bottom to move. Since the lower exhaust duct 34 on the movable cover 15 is blocked, and the air holes on the inner filter ring 4 and the air holes on the outer filter ring 5 are connected, a negative pressure will be generated in the movable cover 15. At this time, the exhaust gas in the outer shell 1 will flow into the movable cover 15 after being filtered by the inner filter ring 4 and the outer filter ring 5. At the same time, the loading plug cylinder 17 drives the adsorption block 18 along the air pressure cylinder The inner wall of the cylinder 20 moves upward to squeeze the gas. At this time, the gas in the air cylinder 20 that has been adsorbed for the first time will pass through the other side of the adsorption block 18 again. Then, the gas adsorbed for the second time by the adsorption block 18 will enter the connecting cylinder 2601 through the vent and the ventilation port 2603 of the inner core cylinder 24, and the gas in the connecting cylinder 2601 will enter the exhaust cylinder 21 through the upper docking port 2602 and the upper exhaust duct 25, thereby achieving efficient adsorption on both sides of the adsorption block 18. The gas in the exhaust cylinder 21 will enter the subsequent processing equipment.

[0060] When the cam 3004 is in the closed position, the cam 3006 is in the closed position, and the cam 3007 is in the closed position, so that the cam 3008 is in the closed position, and the cam 3009 is in the closed position, so that the cam 3009 is in the closed position, and the cam 3008 is in the closed position, so that the cam 3009 is in the closed position, and the cam 3009 is in the closed position, so that the cam 3008 is in the closed position, and the cam 3009 is in the closed position, so that the cam 3009 is in the closed position, and the cam 3009 is in the closed position, so that the cam 3009 is in the closed position,

[0061] S6: Then the device system will control the first electric cylinder 22 to move downward, and the first electric cylinder 22 will push the connecting tube 2601 to move downward, so that the connecting tube 2601 is away from the force ring 27, and the lower docking port 2604 at the bottom of the connecting tube 2601 will be reconnected with the lower exhaust duct 34, so that the gas in the movable cover 15 can be pressed into the air pressure cylinder 20, and the limit plate 28 installed on the side wall of the first electric cylinder 22 moves synchronously, so that the socket 29 on the limit plate 28 can be aligned with the plug rod 3002. At this time, the device system controls the second electric cylinder 33 to start, and the second electric cylinder 33 will push the arc plate 32 to move synchronously, so that the arc The curved plate 32 can push the one-way tooth 3004 in the slot 31 to move, and the one-way tooth 3004 will move out of the slot 31. At the same time, the curved surface of the curved plate 32 will be flush with the inner wall of the exhaust pipe 21. The one-way tooth 3004 drives the plug-in rod 3002 to move synchronously through the guide plate 3001, so that the plug-in rod 3002 can re-enter the socket 29. At this time, the first electric cylinder 22 can drive the loading cylinder 23 to move downward through the limit plate 28 and the plug-in rod 3002, thereby carrying out the next gas processing cycle. When the one-way tooth 3004 leaves the slot 31, the second electric cylinder 33 will drive the curved plate 32 to reset.

At this time, the pressure spring (7) can push the lifting ring (6) to move upward and reset through the reset action, and the outer filter ring (5) installed on the top of the lifting ring (6) moves synchronously, so that the air holes on the outer filter ring (5) are misaligned with the air holes on the inner filter ring (4) again to form a blocking structure; S6: Then the device system will control the first electric cylinder (22) to move downward, and the first electric cylinder (22) will push the connecting tube (2601) to move downward, so that the connecting tube (2601) is away from the force ring (27), and the lower docking port (2604) at the bottom of the connecting tube (2601) will be reconnected with the lower exhaust duct (34), so that the gas in the movable cover (15) can be pressed into the air pressure cylinder (20), and the limit plate (28) installed on the side wall of the first electric cylinder (22) moves synchronously, so that the socket (29) on the limit plate (28) can be aligned with the plug rod (3002), and the device system controls the second electric cylinder (33) to start, and the second electric cylinder (33) will push the arc plate (32) to move synchronously, so that the arc plate (32) can push the one-way tooth (3004) in the slot (31) to move, and the one-way tooth (3004) will move out of the slot (31). At the same time, the arc surface of the arc plate (32) will be flush with the inner wall of the exhaust pipe (21). The one-way tooth (3004) drives the plug rod (3002) to move synchronously through the guide plate (3001), so that the plug rod (3002) can re-enter the socket (29). At this time, the first electric cylinder (22) can drive the loading cylinder (23) to move downward through the limit plate (28) and the plug rod (3002), thereby performing the next gas processing cycle. When the one-way tooth (3004) leaves the slot (31), the second electric cylinder (33) will drive the arc plate (32) to reset.
