| Abstract |
The report describes experiments to improve fabric filter efficiency and pressure drop by use of electric fields near the filter surface. Modified fiber geometries and fabric construction are also investigated. Tests with patch filters showed pressure drops reduced to about 13 mm H2O from about 36 mm H2O upon the application of a 6 kV/cm electric field. Total fractional particle penetration was reduced to about 0.001 from 0.170 under the influence of the same field. The electric field was more effective when applied to filters having loose fibers at the surface. Deeply lobed fibers produced filters with higher efficiency, lower pressure drop, and better cleanability than filters made from round fibers. The effects were attributed to induced localized fields at the lobed surfaces. The fields were produced from collection of naturally charged particles. Fabric structure that promotes particle collection near the upstream surface of the filter gave the best performance. |
