Electrical Stimulation of Fabric Filtration

Abstract

Further progress in developing techniques for electric stimulation of fabric filtration (ESFF) will require that baghouse users participate in testing the concept and providing valuable feedback from full-scale operation experience. Participation is more likely if the ESFF system is simple, relatively inexpensive, and easy to maintain. The original one-bag laboratory baghouse developed at TRI consisted of a bag fitted with alternate live and ground wires spaced an inch apart. An approach to simpler systems has taken the form of a charged axial electrode (or "axode") with all bag electrodes grounded. The work described here centers on further simplification and optimization of this arrangement, studying the effect of axode diameter and number of grounded wires in the bag, including a system requiring no bag wires.
