[0002] During the production process of a rubber compound factory, a large amount of dust-containing waste gas is generated in the crushing and batching processes. The dust particles in these waste gases not only pollute the environment but also pose a threat to the health of workshop operators. Prolonged exposure to such an environment may lead to respiratory diseases. At the same time, the fine particulate matter in the dust-containing waste gas will deposit on the surface of equipment, increasing equipment wear, reducing production efficiency, and affecting the normal operation of the production line. Therefore, how to efficiently collect and treat the dust-containing waste gas in the crushing and batching processes has become an important issue faced by rubber compound factories.

[0003] Existing waste gas treatment systems often have disadvantages such as low capture efficiency, large equipment floor area, and high operating costs. At the same time, the waste gas components generated in different processes vary greatly. For example, the crushing process is mainly dust, while the waste gas in the batching process may contain certain chemical odors. Therefore, conventional waste gas treatment systems are difficult to meet the waste gas treatment requirements of different processes. In addition, the selection of waste gas treatment equipment materials is also a major challenge. Traditional equipment materials may not be able to withstand long-term corrosion and high temperatures, affecting the service life of the system. Summary of the Invention
