Abstract

An electrostatic precipitation unit provided on the current market can meet application requirements for common gas and dust removing generally; and however, if dust particles with quite high adhesion force fail to be effectively and timely cleared away from the surfaces of a discharging cathode and a discharging anode, air ionization is affected, that is, the dedusting effect is affected, for example, the dedusting effect is affected during fume treatment. An electrostatic precipitation unit provided by the invention is characterized in that when electrostatic precipitation is performed for a certain period of time, through system control, a pull plate pulls a piston ring and an annular eraser to reciprocate in an anode barrel, and the annular eraser wipes away dust particles adsorbing and depositing on the inner wall of the anode barrel; when the pull plate is continued to be pulled, the right end of an inner rod abuts against the left end surface of a stopping block to press a spring, so that chuck assemblies slide on a cathode barrel, annular brushes on the chuck assemblies clear conical burrs on cathode rings away, and accordingly the cathode and anode are cleaned; and the intensity of a high voltage electric field is not affected by deposition of the dust particles, and long-term stable operation of equipment is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electrostatic dust removal, in particular to an electrostatic dust removal unit with clean cathodes and anodes. Background technique [0002] Electrostatic precipitator technology is widely used in industry and other fields. Dusty gas is electrostatically ionized when passing through a high-voltage electrostatic field, and dust particles and negative ions are combined with negative charges, and tend to discharge and deposit on the surface of the anode. It is used to purify gas or recover useful dust particles in metallurgical and chemical industries. In the strong electric field, the air molecules are ionized into cations and electrons, and the electrons encounter dust particles in the process of running to the positive electrode and adsorb each other to make the dust particles negatively charged, and finally adsorb to the anode; the cations adsorb the dust particles, making the dust particles positively ...
