[0012] The beneficial effects of the utility model are:

[0013] 1. When the utility model is in use, a motor is set, and the motor drives the threaded rod to rotate. When the threaded rod rotates, the piston plate is driven to move up and down on the threaded rod. When the piston plate moves down, the exhaust gas collected in the collection tank is compressed, and the exhaust gas is discharged into the exhaust gas treatment box through the exhaust pipe by opening the solenoid valve. After the exhaust gas passes through the activated carbon plate, the harmful substances in the exhaust gas are adsorbed, and the purified gas is discharged out of the exhaust gas treatment box through the vent. The device has a simple structure, and the exhaust gas can be treated by regularly starting the motor and the solenoid valve to avoid energy waste caused by continuous operation of the equipment.

[0014] 2. When the utility model is in use, an electric heating network and a fan are set.

[0022] In this embodiment, when collecting exhaust gas, the one-way valve 3 is first opened, and the exhaust gas is input into the collecting tank 1 through the intake pipe 2. When the exhaust gas stored in the collecting tank 1 is completed, the motor is started, and the motor drives the threaded rod 8 to rotate. When the threaded rod 8 rotates, it drives the piston plate 9 to move up and down on the threaded rod 8. When the piston plate 9 moves down, the exhaust gas collected in the collecting tank 1 is compressed. At this time, the solenoid valve 6 is opened, and the exhaust gas is discharged into the exhaust gas treatment box 7 through the exhaust pipe 5. After the exhaust gas passes through the activated carbon plate, the harmful substances in the exhaust gas are adsorbed, and the purified gas is discharged out of the exhaust gas treatment box 7 through the vent 13. By starting the electric heating network 11 and the fan, the fan blows the heat generated by the electric heating network 11 onto the activated carbon plate to thermally activate the filter plate 12, thereby disinfecting the harmful substances on the activated carbon plate and restoring the adsorption performance of the activated carbon plate.

[0032] In this embodiment, by setting up an activated carbon plate, the adsorption effect on harmful substances in the exhaust gas is improved, and its adsorption performance can be restored by thermal regeneration or chemical regeneration, thereby reducing operating costs and the generation of solid waste.

[0033] Working principle: when collecting the exhaust gas, first open the one-way valve 3, and the exhaust gas is input into the collection tank 1 through the intake pipe 2. When the exhaust gas is stored in the collection tank 1, the motor is started, and the motor drives the threaded rod 8 to rotate. When the threaded rod 8 rotates, it drives the piston plate 9 to move up and down on the threaded rod 8. When the piston plate 9 moves down, the exhaust gas collected in the collection tank 1 is compressed. At this time, the solenoid valve 6 is opened, and the exhaust gas is discharged into the exhaust gas treatment box 7 through the exhaust pipe 5. After the exhaust gas passes through the activated carbon plate, the harmful substances in the exhaust gas are adsorbed, and the purified gas is discharged out of the exhaust gas treatment box 7 through the vent 13. By starting the electric heating network 11 and the fan, the fan blows the heat generated by the electric heating network 11 onto the activated carbon plate to thermally activate the filter plate 12, thereby disinfecting the harmful substances on the activated carbon plate and restoring the adsorption performance of the activated carbon plate.
