ELECTROSTATIC PRECIPITATOR

WIPO Patent Application WO/2020/026370

A1

The present invention provides an electrostatic precipitator in which it is possible to enhance the collection efficiency by suppressing effects in the ionic wind that reduce the collection effectiveness of the device. The electrostatic precipitator (1) comprises collecting electrodes (4) which have a plurality of openings formed therein and are provided along the direction of gas flow G, and discharging electrodes (5) which are disposed parallel to the collecting electrodes (4), wherein the discharging electrodes (5) have a plurality of corona discharge units (8) for corona discharge that protrude toward only one collecting electrode (4) among facing collecting electrodes (4) and are provided successively in the direction of gas flow. The plurality of collecting electrodes (4) and the plurality of discharging electrodes (5) are alternately arranged in a direction orthogonal to the direction of gas flow G. All of the respective corona discharge units (8) in an upstream region (S1) and in a downstream region (S2) in the direction of gas flow G protrude toward the same direction.
