[0002] Dust-containing flue gas generally contains a large amount of harmful substances such as particulate matter, heavy metals, and acidic gases. These substances are not only harmful to human health but also cause serious environmental pollution. Therefore, a reasonable method is needed to treat the flue gas. However, currently, the flue gas treatment generally filters and adsorbs the dust in the flue gas through a dust removal bag. After long-term use, the dust accumulates on the surface of the dust removal bag, which will affect the dust removal efficiency and lead to a deterioration in the flue gas treatment effect. Moreover, the adsorbed dust is generally treated by blowing, and there will be some dead corners that cannot be treated, and the dust removal bag cannot be thoroughly cleaned, resulting in a deterioration in the dust removal effect.
