(57) [Summary] [Purpose] To prevent the generation of noise and fire due to the discharge of parallel electrode groups, and also to prevent the generation of ozone odor due to corona discharge. [Structure] When the blower 6 is driven, gas moves in the duct 1 from upstream to downstream. Then, the electrically neutral dust d contained in the gas comes into contact with the charging mesh member 3 connected to the negative electrode of the direct current power source 5 to be negatively charged, and further, the negatively charged dust d is The adsorption filter member 4 connected to the positive electrode of the DC power source 5 is attracted and adsorbed by the Coulomb force. The gas that has become clean due to the dust d being adsorbed on the adsorption filter member 4 is sent out of the electrostatic precipitator by the blower 6. |
