Real-Time Measurements and Control of Particle Charge as Applied to Electrostatically Enhanced Fabric Filters. Technical Progress Report

摘要

The charge and size distribution of particles and the electric field on a filter medium play important roles in increasing particulate collection efficiency, decreasing the filter resistance coefficient and improving filter cleanability of electrostatically enhanced fabric filters (ESFF). To determine quantitatively the effect of the particle's electrical mobility on the performance of an ESFF, it is necessary to perform laboratry experiments on test aerosols where both particle charge and size distribution are varied with an applied electrical field across the filter medium.
