ABSTRACT:
A particle charging device is herein disclosed in which discharge electrodes and opposite electrodes are disposed in an opposed relationship, third electrodes being provided in the proximity of each said discharge electrode, and there are provided a high voltage source for applying a periodically varying high voltage between said discharge electrodes and said third electrodes, a D.C. voltage source for applying a D.C. bias voltage between the above described electrodes, and a D.C. high voltage source for applying a D.C. high voltage between said third electrodes and said opposite electrodes, whereby during the periods when the periodically varying high voltage is not applied between said discharge electrodes and said third electrodes, D.C. corona discharge originating from said discharge electrodes may be always suppressed. Also an electric dust collecting apparatus making use of said particle charging device is disclosed herein.
