Discharge Characteristics and Applications for Electrostatic Precipitation of DC Corona with Spraying Discharge Electrodes

摘要

Some new electrode configurations and high-voltage insulation have been employed in order to force the water sprays to pass across the near corona region. In these ways, the efficiencies of charging and collecting aerosol particles increase. At the same time, the sprays ejecting from the discharge electrodes can overcome some difficulties in electrostatic precipitation, such as the back ionization of dusts with high resistivity, the reentrainment of fine dusts and the fouling of discharge electrodes. In resent years, there are increasing demands for the research of theory and application on this type of corona discharge. In this paper, we introduced the discharge characteristics and some examples for application of the DC corona with spraying discharge electrodes.
