  • Chain-type discharge wire for use in an electrostatic precipitator
    Patent number: 5210678
    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.
