Abstract

n current study, the energy utilized by two types of laboratory based electrostatically assisted pulse jet filtration set-ups, viz. flat media test rig and tubular based test rig has been analyzed and compared. Three types of polyester nonwoven conductive filter media viz. polytetraflouroethylene coated media, stainless steel fibre blended with polyethylene terephthalate media and stainless steel scrim media have been characterized on both setups at three levels of aerosol charge, viz. 4 kV, 8 kV, 12 kV and without charge. The results reveal a significant drop in energy utilization ranging from 20% to 35% at pre-charge levels for both setups. Among all three materials, polytetraflouroethylene coated material is known to perform the best in both test setups. The contribution of compression energy in total power consumption is found to decrease in tubular based setup. However, the total energy consumption has been found to be the lower for flat media test rig.
