Ionized Fields in Electrostatic Separation. Applications to Secondary Materials.
NTIS: PB 200 047 :12 pages
Calculations based on data related to the electrostatic precipitator illustrate the variation in the electric forces on a particle with change in position in the ionized field. The feeble forces in some separators are explained by the low field intensity at midpoint locations between the electrodes. When the particles are in contact with the exterior surface of a rotating cylindrical electrode, a high field intensity at the electrode surface combined with the image charge results in large electric forces. The permissible feed velocity increases as the square root of the electrode diameter, providing high values in efficiency and feed rate capacity, particularly in surface-to-mass ratio separations such as are encountered in secondary materials recycling operations.
