ELECTROSTATIC PRECIPITATOR

摘要

Disclosed is an electrostatic precipitator which can efficiently eliminate dust attached on a dust collecting plate via a simple configuration. The electrostatic precipitator comprises: a duct collecting module having dust collecting components which ionize sucked dust and adsorb the ionized dust; a blowing module sucking external air into the dust collecting module; a power source module having a unit connecting electric signals with the dust collecting module and the blowing module, generating high voltage to perform ionizing and dust collecting functions and supplying the high voltage to the dust collecting module, and supplying driving power to the blowing module; and an air injection pipe provided at the dust collecting module to be rotatable and having a plurality of injection holes located eccentrically in a circumferential direction to inject the air via the injection holes. Therefore, the present invention maintains cleanness in a workplace, reducing volume and weight to be easy to move, continuously maintains high dust collecting efficiency and reduces manufacturing costs.
