Abstract
An improvement in an electrostatic precipitator and method for removing particulate contaminants entrained in a gas stream passed through an electrode arrangement in which particulates are charged in a first electrostatic field and subjected to a second electrostatic field to be removed and collected for further disposition. The electrode arrangement includes a charging section having a charging electrode and a field electrode, and a collecting section having a repelling electrode and a collecting electrode. The field electrode and the collecting electrode are integrated, providing a relatively compact construction, and the charging electrode and the repelling electrode are electrically separated by high voltage diodes in a single power supply arrangement such that the charging section and the collecting section each are provided with a corresponding electrostatic field operated at an optimum voltage and current for respectively charging and collecting particulate contaminants entrained in the gas stream.
