Chip type cathode wire of electrostatic dust collector

Abstract

The invention discloses a chip type cathode wire of an electrostatic dust collector. The chip type cathode wire comprises a cathode pole (1), wherein gear shaped barb pieces (2) are vertically arranged on the cathode pole (1) in a sheathed manner, the inner circle of each barb piece (2) is matched with the outer circle of the cathode pole (1), the top ends of gear teeth at the outer circumference of the barb pieces (2) are sharp-angled discharging ends and the sharp-angled discharging ends on the adjacent barb pieces (2) are staggered from one another or aligned to one another. According to the chip type cathode wire of the electrostatic dust collector, the gear shaped barb pieces are adopted, the ratio of the inner circle, the tooth root circle and the tooth top circle of each barb piece and the thickness of each barb piece are particularly defined, the top ends of the gear teeth on the outer circumference of the barb pieces are defined as the sharp-angled discharging ends and the sharp-angled discharging ends on the adjacent barb pieces are staggered from one another or aligned to one another, therefore, the cathode wire with the barb pieces has the characteristics of low corona onset voltage, high electric field intensity and uniform electric field distribution, has a simple structure, and is easy to manufacture and install and further suitable for promotion and application.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a sheet-type cathode wire for an electrostatic precipitator. Background technique [0002] The cathode wire is one of the core components of the electrostatic precipitator, and the structure of the cathode wire directly affects the dust removal and mist removal efficiency of the electrostatic precipitator. At present, the cathode wires of electrostatic precipitators are mostly star-shaped wires, zigzag wires, and 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 novel high-efficiency, simple-structured, easy-to-manufacture and install sheet-type cathode wire for electrostatic precipitators. The cathode wire has high rigidity and strength, and is not easy...
