The cleaning mechanism 14 comprises a dust suction housing 143 installed on the side surface of the rotating shaft 17, and a cleaning brush 141 is arranged on the side of the dust suction housing 143 close to the first filter screen plate 9; a driving component 18 for driving the rotation of the rotating shaft 17. It further comprises a moving mechanism 15 for stirring the heat exchange liquid in the heat exchange chamber 32 while the dust suction housing 143 rotates with the rotating shaft 17. The moving mechanism 15 comprises a moving magnetic component 151 installed at one end of the dust suction housing 143 away from the rotating shaft 17, and a magnetic housing 153 installed in the heat exchange chamber 32 through an elastic component 152. The position of the magnetic housing 153 corresponds to the position of the moving magnetic component 151.

[0023] During use, the housing 1 is installed and fixed at the opening of the exhaust gas component 7 through the fixing mechanism 6. The air extraction component 19 extracts air from the interior of the housing 1, enabling the exhaust gas in the exhaust gas component 7 to enter the housing 1 through the heat exchange housing 33. The first filter plate 9 filters the exhaust gas entering the heat exchange housing 33 and at the same time obstructs the flow of the exhaust gas entering the heat exchange housing 33, increasing the contact time between the exhaust gas and the inner wall of the heat exchange housing 33, so that the heat in the exhaust gas can be effectively conducted to the heat exchange liquid, recycling the heat energy in the exhaust gas. At the same time, the driving component 18 drives the rotating shaft 17 to rotate, thereby driving the dust suction housing 143 and the cleaning brush 141 to rotate and cleaning the side surface of the first filter plate 9 to ensure the filtering effect of the first filter plate 9. While the dust suction housing 143 is rotating, the movable magnetic component 151 rotates horizontally with the dust suction housing 143 and reciprocates closer to and farther away from the magnetic housing 153. Under the magnetic force of the movable magnetic component 151 on the magnetic housing 153, when the movable magnetic component 151 passes by the magnetic housing 153, the magnetic housing 153 swings in the heat exchange chamber 32 under the magnetic force and the elastic action of the elastic component 152, thereby realizing the agitation of the heat exchange liquid in the heat exchange chamber 32 and improving the heat exchange efficiency.

When the dust collection shell 143 drives the cleaning brush 141 to rotate along with the rotating shaft 17, the cleaning brush 141 brushes off the dust on the side of the first filter plate 9. At the same time, the dust brushed off is promptly vacuumed through the dust collection pump and the dust collection hole 142 to prevent the dust brushed off the first filter plate 9 from falling onto the first filter plate 9 at a low level, thereby ensuring the cleaning effect of the first filter plate 9.

[0029] As a preferred embodiment of the present invention, the inner wall of the heat exchange chamber 32 is staggered with flow blocking components 10, which are used to block the heat exchange liquid flowing in the heat exchange chamber 32, so that the heat exchange liquid injected into the heat exchange chamber 32 through the water inlet pipe 31 can fully and effectively contact with the exhaust gas, thereby improving the heat exchange effect.

[0030] As a preferred embodiment of the present invention, the fixing mechanism 6 includes a telescopic member 61 installed on the side of the shell 1, and a clamping member 62 is provided at one end of the piston rod of the telescopic member 61.

After the shell 1 is fixed, the air pump 5 is used to inflate the inside of the first sealing airbag 41 and the second sealing airbag 8. The first sealing airbag 41 is inflated and expands to seal the gap between the shell 1 and the outer wall of the smoke exhaust component 7, and the second sealing airbag 8 is inflated and expands to seal the gap between the outer wall of the heat exchange shell 33 and the inner wall of the smoke exhaust component 7. It is suitable for smoke exhaust components 7 of different calibers and has a wider range of applications.

The air purified by the adsorption material enters the transition housing 21 through the air inlet hole 24, and the gas is sprayed to the bottom of the purification liquid through the air outlet hole 23. At the same time, the rotating shaft 17 drives the second stirring member 16 to rotate to stir the purification liquid, so that the gas can fully contact in the purification liquid. When the tail gas treatment is stopped, the water separation member 22 separates the purification liquid flowing back into the transition housing 21 through the air outlet hole 23 to prevent the purification liquid from flowing to the bottom of the partition plate 13 through the air inlet hole 24.

[0035] In use, the housing 1 is fixedly installed at the opening of the exhaust gas component 7 through the fixing mechanism 6. The air extraction component 19 extracts air from the interior of the housing 1, so that the exhaust gas in the exhaust gas component 7 enters the housing 1 through the heat exchange housing 33. The first filter plate 9 filters the exhaust gas entering the heat exchange housing 33 and at the same time blocks the flow of the exhaust gas entering the heat exchange housing 33, increasing the contact time of the exhaust gas with the inner wall of the heat exchange housing 33, so that the heat in the exhaust gas can be effectively conducted to the heat exchange liquid, recovering and utilizing the heat energy in the exhaust gas. At the same time, the driving component 18 drives the rotating shaft 17 to rotate, thereby driving the dust suction housing 143 and the cleaning brush 141 to rotate, and cleaning the side surface of the first filter plate 9 to ensure the filtering effect of the first filter plate 9. While the dust suction housing 143 is rotating, the movable magnetic component 151 rotates horizontally with the dust suction housing 143 and reciprocates close to and away from the magnetic housing 153. Under the magnetic force of the movable magnetic component 151 on the magnetic housing 153, when the movable magnetic component 151 passes by the magnetic housing 153, the magnetic housing 153 swings in the heat exchange cavity 32 under the magnetic force and the elastic action of the elastic component 152, thereby realizing the agitation of the heat exchange liquid in the heat exchange cavity 32 and improving the heat exchange efficiency; while the magnetic housing 153 is swinging, the movable component 154 moves in the magnetic housing 153, and at the same time the heat exchange liquid enters and exits the magnetic housing 153 through the perforations 155, improving the agitation effect on the heat exchange liquid; while the dust suction housing 143 drives the cleaning brush 141 to rotate with the rotating shaft 17, the cleaning brush 141 brushes off the dust on the side surface of the first filter plate 9, and at the same time timely sucks the brushed-off dust through the dust suction pump and the dust suction holes 142, preventing the dust brushed off from the first filter plate 9 from falling onto the first filter plate 9 at a lower level position and ensuring the cleaning effect on the first filter plate 9.
