Gas harmless treatment device for automobile sealing strip production Technical Field The invention relates to the technical field of industrial waste gas treatment, in particular to a gas harmless treatment device for producing an automobile sealing strip. Background With the rapid development of the automobile industry in China and the increasingly strict environmental protection regulations, the problem of exhaust emission in the production process of automobile parts is highly valued. In the production process of the automobile sealing strip, particularly in the working procedures of mixing, extruding, vulcanizing, surface treatment and the like of rubber or plastic, a certain amount of Volatile Organic Compounds (VOCs) and other harmful gases can be generated. If the waste is not effectively treated and directly discharged, the waste can threaten the health of workers in workshops and can pollute the surrounding atmospheric environment. Therefore, the development of an efficient, reliable and economic waste gas harmless treatment device has become an urgent requirement for realizing green production and meeting the environment-friendly compliance requirement for automobile sealing strip manufacturing enterprises.
