Electrostatic precipitator

摘要

An electrostatic precipitator (1) including a charger (10) to charge dust particles in air and a collector (20) to collect the dust particles. The collector (20) includes a collector case (100) including high-voltage electrodes (300), to which high-voltage is applied, low-voltage electrodes (400) alternately stacked with the high-voltage electrodes (300) so as to be grounded, and first electrode support elements (130) to support the high-voltage (300) and low-voltage electrodes (400) with a distance therebetween. The first electrode support elements (130) include electrode contact terminals (510, 520) to support extreme edge portions of the high-voltage (300) and low-voltage electrodes (400). The high-voltage (300) and low-voltage electrodes (400) are formed of a conductive material, or a non-conductive material, the surface of which is subjected to conductive treatment. The electrode contact terminals (520) for the high-voltage electrodes (300) are formed of a semiconductive material. Accordingly, it is possible to maintain a constant distance between the electrodes and to prevent insulation breakdown without deterioration in the performance of the collector (20).
