Patent ID: 8690998

Claim:
An electric precipitator comprising: a charge unit disposed at an upstream part in an air flow direction; and a dust collection unit disposed at a downstream part in the air flow direction, wherein the charge unit includes a plurality of charge electrodes separated from each other, and a discharge wire disposed between two neighboring charge electrodes and separated from the charge electrodes; the dust collection unit includes a plurality of high voltage electrodes, front ends of which are opposite to the charge unit and which are separated from each other, and a plurality of low voltage electrodes, front ends of which are opposite to the charge unit and which alternate with the plurality of high voltage electrodes; and the front ends of the plurality of high voltage electrodes protrude toward the charge unit as compared to the front ends of the plurality of low voltage electrodes; and an insulating member is disposed at a high voltage electrode located in a straight line with the discharge wire in the air flow direction from among the plurality of high voltage electrodes.
