[0002] When waste gas is generated in industrial production and the airflow contains harmful substances, it is necessary to filter and clean the harmful substances in the airflow before discharging. In the field of electroplating, when the workpiece is electroplated in the electroplating tank, a large amount of waste gas will be generated due to chemical reactions and physical volatilization. Therefore, it is necessary to set a waste gas treatment device on the upper side of the electroplating tank to collect the waste gas and protect the surrounding environment. The existing method is generally to suck and discharge the waste gas through the exhaust pipe, and then install a filter element inside the exhaust pipe to filter the waste gas. However, when this method is used, the filter element will become saturated with adsorption after a period of time. Therefore, the filter element needs to be replaced regularly and in a timely manner.
