Cathode wire for wet electrostatic dust collector

Abstract

The invention discloses a cathode wire for a wet electrostatic dust collector. The cathode wire comprises a cathode rod (1), and is characterized in that bur rings (2) are arranged on the cathode rod (1); the discharging points of the bur rings (2) are of sharp-pointed annular or polygonal structures; connecting pieces (4) are arranged at the two ends of the cathode rod (1) respectively, so that the cathode wire is fixed on a cathode frame through the connecting pieces (4). The bur ring type cathode wire is simple in structure and easy to manufacture and mount; the discharging points of the bur rings form the sharp-pointed annular or polygonal structures, so that the bur rings have a discharging function in each direction, and the number of discharging points can be set according to needs; the wet electrostatic dust collector with the cathode wire has the characteristics of low critical coronal voltage, high electric field intensity and uniform electric field distribution, the problem of corona dead zones of a conventional wet electrostatic dust collector is well solved, and the dust collection and defogging efficiency of the wet electrostatic dust collector is further improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a cathode wire for a wet electrostatic precipitator. Background technique [0002] The cathode wire is one of the core components of the wet electrostatic precipitator, and the structure of the cathode wire directly affects the dust removal and mist removal efficiency of the wet electrostatic precipitator. At present, the cathode wires of wet electrostatic precipitators are mostly star-shaped wires, zigzag wires, ordinary prickly wires, etc., with low current density, corona dead zone, and unsatisfactory dust and fog removal effects. Contents of the invention [0003] The object of the present invention is to solve the problems existing in the prior art, and provide a new type of cathode wire for wet electrostatic precipitator with high efficiency, simple structure, and easy manufacture and installation. The cathode wire has high rigidity and strength, is not ...

AI Technical Summary

Problems solved by technology

At present, the cathode wires of wet electrostatic precipitators are mostly star wires, zigzag wires, ordinary prickly wires, etc., the current density is low, there is a corona dead zone, and the effect of dust removal and fog removal is not ideal.
