ELECTROSTATIC PRECIPITATOR

摘要

An electrostatic precipitator (1) comprising a housing (8) having an air duct (7) for communication between an inlet (4) for sucking contaminated air (3) and an outlet (6) for discharging cleaned air (5), a section (10) for generating an air flow (9) in the air duct (7), a collecting section (14) having a plurality of adsorption plates (13) rotating in accordance with an adsorption shaft (11), and a discharge section (24) equipped with a charging plate (20) having a discharge surface (21) opposing to the adsorption surface (12) of the adsorption plate (13) and a plurality of discharge electrodes (19) provided at the edge (22) of the charging plate (20) opposing to the suction inlet. Fine particles (2) contained in the contaminated air (3) are charged by corona discharge (CD) generated from the pointed ends (23) of the discharge electrodes (19) and collected by using the Coulomb force while varying relative positional relationship of the fine particles (2) and the adsorption surface (12) at all times by means of the rotating adsorption plate (13).
