The movable cylinder 204 is driven to slide and rise relative to the bracket 201 through the hydraulic rod 203.

[0030] In this embodiment: the liquid guiding component 3 includes a water inlet joint 301 which is respectively fixedly connected to the fixed cylinder 202 and the movable cylinder 204, a drainage joint 302 is arranged on one side of the water inlet joint 301, and a liquid inlet joint 303 is fixedly connected to the fixed cylinder 202; water that can cool down the fixed cylinder 202 and the movable cylinder 204 is introduced into the fixed cylinder 202 or the movable cylinder 204 through the water inlet joint 301, the heated water is discharged through the drainage joint 302, and a certain amount of liquid agent that can harmlessly treat the exhaust gas is introduced into the area where the rotating cylinder 206 is located between the fixed cylinder 202 and the movable cylinder 204 through the liquid inlet joint 303.

[0032] Working principle: When the device is installed and used for waste gas treatment of biomass boilers, it is necessary to move the device to the vicinity of the biomass boiler and align the air inlet hood 401 with the position where the waste gas is generated by the biomass boiler. Then, the water inlet joint 301 and the drainage joint 302 are connected to the external water circulation equipment so that the cooling water can enter the fixed cylinder 202 or the movable cylinder 204 along a fixed path and flow out.

[0033] After the above preparations are completed, the motor 210 and the induced draft fan 404 can be operated to suck the exhaust gas generated by the biomass boiler into the continuously rotating drum 206 through the air intake hood 401, and evenly spray it between the area surrounded by the fixed drum 202 and the movable drum 204 through the mesh of the filter 208. In this process, the exhaust gas will be filtered by the filter 208, cooled by the water in the fixed drum 202 and the movable drum 204, and react with the treatment liquid under the drum 206 in turn, so that the device can complete the purification of the exhaust gas and the recovery of waste heat. The treated exhaust gas will leave the device along the air guide joint 402, the connecting pipe 403, and the induced draft fan 404 in turn;

[0034] During the use of this device, it is necessary to regularly open the liquid inlet joint 303 to replace the treatment liquid, and after the hydraulic rod 203 drives the movable cylinder 204 to rise to a certain height to separate from the fixed cylinder 202, remove the frame 207 and disassemble and clean the filter 208 thereon, so as to ensure the exhaust gas treatment effect and service life of the device.
