[0002] In the field of industrial waste gas treatment, dust removal and pretreatment devices play a vital role, and their background technology involves complex process flows and efficient purification methods. Industrial waste gas often contains a large amount of impurities such as particulate matter, smoke, heavy metals, halogen compounds, etc. These impurities not only cause serious pollution to the environment, but also may pose a threat to human health. In the existing industrial waste gas pretreatment, most of them use filters and other methods to achieve overall pretreatment and filtration of industrial waste gas particulate impurities.
