Abstract
The paper discusses an EPA program to develop engineering data for the application of electrostatics to fabric filtration in the form of integral particle charging and collection in a combined electric and flow field, which causes particle deposition to be dominated by electrostatic precipitation rather than by porous flow collection. A mathematical model was developed to predict the nonuniform deposition of the particulate matter and the relative pressure drop that would result from it. The model predicts both the nonuniform deposition and relative pressure drop with reasonable accuracy. Also investigated as part of the program was the use of pulse energization to equalize the corona currents among a number of electrified bags powered by the same electric power supply. Energizing the bags decreased the penetration of particles > 0.8 micrometer; the trend suggested that it should also be possible to decrease the penetration of particles < 0.8 micrometer.
