The wet dust collector is suitable for treating dust in a wet environment, but the dust collection efficiency of the existing wet dust collector is relatively low, and the current environmental-friendly emission standard requirement cannot be met.

Therefore, the research of the dust remover which has high dust removal efficiency, can meet the current environment-friendly emission requirement and can adapt to the dust treatment in the wet environment of the mine has important significance for ensuring the green development of the mining.
