[0036] In the embodiment, the top end inner wall of the corrugated pipe 5 is fixedly connected with a horizontal plate 501, the top of the horizontal plate 501 is fixedly connected with a top rod 502, the bottom end inner wall of the connecting pipe 6 is fixedly connected with a sealing ring 601, the inner wall of the sealing ring 601 is provided with a sealing disc 602, the top of the sealing disc 602 is fixedly connected with two third limiting rods 603, the third limiting rod 603 is sleeved with a third sleeve plate 604, the third sleeve plate 604 is fixedly connected with the inner wall of the connecting pipe 6, the third limiting rod 603 is sleeved with a first spring 605. Since the technology of rising the sealing disc during the expansion of the corrugated pipe is adopted, the rising of the sealing disc no longer contacts the sealing ring, the exhaust gas can be discharged from the corrugated pipe to the connecting pipe, and when the corrugated pipe is contracted, the sealing disc contacts the sealing ring, so that the exhaust gas can be prevented from entering the connecting pipe, thereby achieving the sealing effect.

[0037] Working principle: when using the device, through the inlet pipe 4 into the box 1, before the lower activated carbon layer 3 is full of attachments, the exhaust gas is treated by the lower activated carbon layer 3, the harmful substances in the exhaust gas are adsorbed by the lower activated carbon layer 3, and the emission concentration is reduced. When the lower activated carbon layer 3 is inside the box 1, the two sealing rings 7 do not contact, and the exhaust gas is discharged from the corrugated pipe 5. At this time, the sealing disc 602 contacts the sealing ring 601, plays a sealing role, and the exhaust gas cannot enter the connecting pipe 6. The exhaust gas cannot contact the upper activated carbon layer 2. The exhaust gas treated by the lower activated carbon layer 3 is discharged through the outlet pipe 10 and finally discharged through the gas outlet 12. When the lower activated carbon layer 3 is full of attachments, the lower activated carbon layer 3 is pulled out, the screw on the sealing plate 19 at the bottom is removed, the sealing plate 19 is removed, and the square plate 18 is also removed. When the square plate 18 is removed, the square plate 18 cannot extrude the round rod 17, the second spring 21 can be stretched, the first sleeve plate 2001 is pushed up, the first sleeve plate 2001 drives the corrugated pipe 5 to stretch, the corrugated pipe 5 drives the sliding rod 13 to rise, the sliding rod 13 extrudes the side plate 14 to move the side plate 14 to the square plate 18, the side plate 14 moves to drive the second sleeve plate 24 to move, the second sleeve plate 24 moves along the second limiting rod 25. When the square plate 18 is removed, the two sealing rings 7 contact each other to play a sealing role. In the process of stretching the corrugated pipe 5, the horizontal plate 501 is also lifted, the horizontal plate 501 drives the top rod 502 to rise, the top rod 502 rises to contact the sealing disc 602 to continue to rise and drive the sealing disc 602 to rise. The sealing disc 602 drives the third limiting rod 603 to move along the third sleeve plate 604. The sealing disc 602 rises to extrude the first spring 605 to make the first spring 605 contract. The exhaust gas is injected into the connecting pipe 6 through the corrugated pipe 5, discharged through the connecting pipe 6, so that the exhaust gas can be treated by the upper activated carbon layer 2. Through the isolation of the partition plate 11, the exhaust gas cannot flow to the lower activated carbon layer 3. The exhaust gas is treated by the upper activated carbon layer 2 and discharged from the gas outlet 12. When the attachments on the upper activated carbon layer 2 are full, a new lower activated carbon layer 3 is inserted into the box 1, the sliding block 8 is aligned with the sliding rail 9 and moves along the sliding rail 9, and then the sealing plate 19 is installed. The opening of the box 1 at the position of the sealing plate 19 is sealed by the sealing gasket 23, and the sealing plate 19 is fixed on the fixed frame 22 by screws. In this process, the square plate 18 extrudes the round rod 17 to make the round rod 17 move, the round rod 17 drives the fixed plate 16 to move, the fixed plate 16 drives the side plate 14 to move, the side plate 14 extrudes the sliding rod 13 to make the sliding rod 13 descend, the sliding rod 13 descends to make the corrugated pipe 5 contract, so that the two sealing rings 7 do not contact, and the exhaust gas can be discharged from the corrugated pipe 5 again, so that the exhaust gas can be treated by the lower activated carbon layer 3. When the corrugated pipe 5 contracts, the top rod 502 descends, the first spring 605 stretches,In order to make the sealing disc 602 to descend and contact with the sealing ring 601, the sealing is carried out, and the exhaust gas is prevented from entering into the connecting pipe 6, and the upper active carbon layer 2 is extracted and replaced according to the same steps.
