Bipolar Precharger for Hybrid Electrostatic Filtration Systems

Both hybrid electrostatic filtration and agglomeration technologies can effectively improve the efficiency of fine particle collection. A system with a wire–tube bipolar precharger was developed on basis transverse plate precipitation technology. Theoretical analyses electric field flow distribution showed that uniform high turbulence intensity ion migration in novel precharger. The influence unipolar prechargers dust removal investigated. In precharger, corona current 30% higher, particles deposited surface filter bag were 19% larger, pressure drop smaller than When silicon powder median diameter 1.7 μm used, mean penetration experimental device 45% lower
