In a non-uniform electric field formed by the dust-containing gas passing through a high-voltage direct-current power supply, the negative electrode of the power supply is called as a cathode, a discharge electrode and a corona electrode, the positive electrode of the power supply is called as an anode, a collector and a precipitation electrode, and the electric field intensity near the cathode forces the gas to collide and ionize to form a large amount of positive and negative ions. Most of dust collides with negative ions to be charged negatively and flies to a dust collecting electrode, only a very small amount of dust is accumulated on the corona electrode, the dust collecting electrode and the corona electrode are periodically shaken, and the dust adsorbed by the two electrodes falls into a dust collecting hopper. After the electric dust collector operates for a period of time, dust adhesion can occur on the electrode wires and the polar plates, after the electrode wires of the electric dust collector are adhered, the discharge tips on the electrode wires are shielded, dust-containing smoke passes through the electric dust collector, dust cannot be effectively charged, and the dust collection efficiency of the electric dust collector is reduced. At present, the polar plates and the polar plates of the electric dust collector are generally treated by three modes of water washing, sand blasting, polar plate replacement.
