[0002] PS sheet, also known as organic sheet, is a plastic sheet made of polystyrene (PS) as the main raw material. It is widely used in packaging, electrical appliances, construction, transportation, lighting, medicine, industry, advertising and other fields. With the continuous development of the electronics manufacturing industry, the requirements for PS sheet production technology are also constantly improving to meet the changes in market demand.

[0003] In the process of PS sheet processing, waste gas mainly comes from the heating, melting, extrusion, and molding of raw materials, which poses a threat to the environment and human health. In the treatment of waste gas from PS sheet processing, filters are mostly used. Long-term use of filters will cause adhered dust to affect the air permeability of the filters, and workers are required to shut down the machine for cleaning, which is cumbersome and increases time, reducing the efficiency of waste gas treatment. At the same time, during the shutdown of waste gas treatment, external gas is prone to reflux through the outlet pipe, causing external impurities to enter and affect use.

[0036] During use, before collecting the gas, the gas is first filtered through the gas impurity removal mechanism 2 to reduce the particulate impurities in the gas and ensure the cleanliness of the gas. The impurities intercepted on the arc filter 24 are cleaned by the cleaning component 25 provided. The cleaning component 25 realizes the cleaning of the arc filter 24 to ensure the subsequent filtration volume of the arc filter 24 and the filtering effect.
