Electrostatic Collection Efficiency in Binary Fluidized Beds

Abstract

Fluidized beds of binary mixtures have been used to clean air streams containing dust particles in the size range 4.4 to 14 μ. All beds were composed of glass beads and plastic granules mixed at different proportions. The effect on the electrostatic collection efficiency of a number of variables, including type of collecting mixture, bed height, and gas velocity, was examined. To calculate the single collection efficiency from experimental results, an early model proposed by Clift et al. was used. The electrostatic collection efficiency was determined by subtracting the other individual mechanism efficiencies from the single particle collection efficiency.
