<P>PROBLEM TO BE SOLVED: To provide an electrostatic precipitator that can improve the efficiency of collecting particulates by collecting the particulates in the whole passage of particulate-containing gas to be purified, and can burn the collected particulates. <P>SOLUTION: The electrostatic precipitator includes a dust collection part, which has a discharge electrode 26 disposed in a central part, inner electrodes 25 disposed around the discharge electrode 26 so as to keep a predetermined interval therebetween, and outer electrodes 24 supported on the inner peripheral surface of a dielectric 23 disposed outside the inner electrodes 25 so as to keep a predetermined distance, in the gas passage through which the particulate-containing gas to be purified flows. A direct-current voltage is applied between the discharge electrode 26 and the dielectric 23. The particulates are collected on the outer electrodes 24 and inner electrodes 25 by electrostatic fluid force. An alternating voltage is applied between the outer electrodes 24 and the dielectric 23 to burn the collected particulates by plasma generated by surface discharge. <P>COPYRIGHT: (C)2012,JPO&INPIT |
