Patent ID: 8580017

Claim:
An electrostatic precipitator comprising a charger to charge dust particles in air and a collector to collect the dust particles charged in the charger, wherein the collector includes a collector case which is provided with a plurality of high-voltage electrodes, to which high-voltage is applied, a plurality of low-voltage electrodes alternately stacked with the high-voltage electrodes so as to be grounded, first electrode support elements to support the high-voltage electrodes and low-voltage electrodes with a predetermined distance between the high-voltage electrode and the low-voltage electrode, and electrode contact terminals to support extreme edge portions of the high-voltage electrodes and low-voltage electrodes, and wherein the high-voltage electrodes and low-voltage electrodes are formed of a conductive material, or a non-conductive material, the surface of which is subjected to conductive treatment, and the electrode contact terminals for the high-voltage electrodes are formed of a semiconductive material.
