Electric precipitator and electric precipitation electrode used for the same

Abstract

A plurality of discharge electrodes are grouped for respective gas passages that are defined by collecting electrodes (11-15). The discharge electrodes in each group are connected to a common power supply unit for receiving output voltage through a diode provided for each group and are connected to a spark electrode (21). The spark electrode is positioned such that it sparks between a hammer (20) in a passageway of the hammer upon striking. Each group of the discharge electrodes has a ground unit to be grounded just before the collecting electrodes on both sides thereof are struck.
