for a Moving Electrode Type Electrostatic Precipitator
Toshiaki MISAKA*,1, Tadashi OURA* and Takeo ARIMITSU*(Received December 7, 2005; Accepted March 23, 2006)

It is important to improve the collection efficiency of high resistivity dust particles in an electrostatic precipitator.
The moving electrode type electrostatic precipitator, which is equipped with brushes to dislodge dust particles fromthe moving collecting plate surface, is effective for collecting high resistivity dust particles. This paper describes a
study of adhesive force of dust layer on collecting plate surface and dislodgement methods of dust layer from thecollecting plate in an electrostatic precipitator. In the case of FCC (Fluid Catalytic Cracker) dust (dust resistivity=3
1014 ǡ㨯cm), an adhesive force of dust layer exceeds 8,400 N/m2, and it is difficult to dislodge the dust layer by theconventional mechanical rapping system in a collecting plate. For dislodgement of dust layer, the rotating brush type
dust removal device was observed to be effective to dislodge dust layer from collecting plates.
