Particle charging device and an electric dust collecting apparatus

Patent ·
OSTI ID:7277435
A particle charging device is described in which discharge electrodes and opposite electrodes are disposed in an opposed relationship, third electrodes being provided in the proximity of each discharge electrode, and there are provided a high voltage source for applying a periodically varying high voltage between the discharge electrodes and the third electrodes, a dc voltage source for applying a dc bias voltage between the above described electrodes, and a dc high voltage source for applying a dc high voltage between the third electrodes and the opposite electrodes, whereby during the periods when the periodically varying high voltage is not applied between the discharge electrodes and the third electrodes, dc corona discharge originating from said discharge electrodes may be always suppressed. Also an electric dust collecting apparatus making use of the particle charging device is described.
