However, in the actual use process, especially in the case of irregular central inlet pipelines, the current equalizing effect is very poor, so that local cathode and anode dust collection is not carried out in the electric dust removing area, and the damage rate of the filter bag is high due to too high local flow rate in the cloth bag dust removing area.
