ABSTRACT: In this project, some charged characteristics, and analysis of
precipitated PM2.5 in high electrostatic field were calculated based on
theories and experiments. The connection between the charge amount and the
additional electric field intensity caused by the wet flexible collectors was
studied to reveal the mechanism of charging enhancement of PM2.5 on flexible
collectors. Some explanation about the wet ability of collectors and the
current density enhancing the precipitation process was proposed in this
project. Simultaneously, the results shows that both gas treatment time and
applied voltage have an important influence on particle collection, and the
minor factor was initial concentration.
