Abstract
An improved discharge wire for use in an electrostatic precipitator which is used for collecting pollutant particles contained in a flow of exhaust gas. The improved discharge wire is a chain having a plurality of chain links made of conductive material. There is provided at least one needle-like member made of conductive material on at least one of the chain links. As an electric potential is applied to the chain, the needle-like member emits corona current. The corona current charges the pollutant particles such that the pollutant particles are forced by the electric field to a collecting member.
Claims1
A discharge wire for use in an electrostatic precipitator which is used for collecting pollutant particles contained in a flow of exhaust gas, the electrostatic precipitator having a collecting member made of conductive material and a means for impressing an electric field across said discharge wire and the collecting member;, said discharge wire comprising:
- a chain having a plurality of chain links made of conductive material, said chain being disposed near said collecting member;
- at least one needle-like member made of conductive material provided on at least one of the chain links;
- and
- wherein as the electric field is impressed across said chain and the collecting member, said needle-like member will discharge corona current such that pollutant particles nearby are charged and thereby attracted by and accumulated on the collecting member.
