Abstract |
The report gives results of an evaluation of the concept of using electro-fluidized beds for fine particle collection. A simple model was developed to describe the interaction between an aerosol stream and the bed material. Overall collection efficiency of the device was theoretically predicted from single target efficiency values based on electrostatic and inertial forces. Maximum predicted overall collection efficiencies range from 96% for a 1 micrometer aerosol particle to 85% for a 0.5 micrometer aerosol particle, with collector bodies of size 100 micrometers, an availability factor of 0.1, and fluidization velocities of 0.5 ft/sec. An increase in fluidization velocity or a decrease in collector number density (i.e., larger collector bodies) diminishes the overall collection efficiency for the conditions used in this investigation. The performance of the electrofluidized bed depends upon the interaction of the electrostatic forces and bed dynamics. The inherent instability of solids flow patterns in gas-fluidized beds may limit the collection efficiency that can be achieved. |
