ABSTRACT:
An electric dust collector apparatus is disclosed herein; which comprises an inlet port for dust-containing gas, a main body duct of said electric dust collector, an outlet port for clean gas, and an exhaust port for collected dust; a plurality of channel-shaped collector electrodes disposed at an equal interval and in parallel to each other along a plane transverse of a gas flow within the main body duct with their opening directed to an upstream side; a plurality of channel-shaped driver electrodes disposed upstream of said collector electrodes at an equal interval, along a plane transverse of the gas flow within the main body duct in a staggered relationship to said respective collector electrodes, in parallel to each other and to said collector electrodes and as insulated from said collector electrodes with their openings directed to a downstream side; a plurality of corona discharge electrodes disposed midway between adjacent ones of said driver electrodes in parallel thereto and opposed to inner surfaces of the openings of said collector electrodes in parallel thereto, as insulated from both said driver and collector electrodes; a D.C. high voltage source for applying a D.C. high voltage between said driver electrodes and said collector electrodes; a variable D.C. high voltage source for applying a D.C. high voltage having a variable voltage value between said corona discharge electrodes and said driver electrodes, and/or a variable, periodically varying, high voltage source for applying a periodically varying high voltage, whose peak value and/or period are variable, between said corona discharge electrodes and said driver electrodes; and hammering means for applying mechanical impacts to said collector electrodes, driver electrodes and corona discharge electrodes.
