Abstract: It often produces a stronger cohesive force coating to deal with weakening of cohesive force between the
between high resistivity dust and polar plate in ESP,but high resistivity dust and the polar plate.
cleaning and papping always have not been order 2. THEINFLUENCE OF COATING ON FORCE
to reduce cohesive force between high resistivity dust and CONDITIONS OF DUST
polar plate, the influence of coating on force conditions of The existing theory of dust trapping considers that, when dust
dust is analyzed in this paper, through theoretical analysising gets into the border region of laminar flow where Coulomb
and calculating the appropriate coating materials are selected, force plays the role, and attaches to the collecting dust polar
and experimental equipment is designed by the authors. Based plate, the dust can be arrested on the set.
on the experimental results, the coating can significantly After dust particles in the electric force field are separated
