Experimental Study On Strengthen The Performance Of Electrode Dust Collection Of Electrostatic Precipitator

There is a lot of particles that charge electropositive and neuter ion in exits of electrostatic precipitator. Particles that charge electropositive ion can account for 30%~50% of total amount. Strengthen the ability of collecting these dust of cathode of electrostatic precipitator, so the precipitation efficiency can be improved greatly. The objective of the study reported on this paper was to investigate the mechanisms and approaches of improvement the potential of collection dust of cathode. And under the guidance of theory, Designed and made the new-type cathode that has multi-function of collecting dust, minishing the lost of second blowing dust, weaken and overcome the discorona. Discharging characteristics of different cathode line which matching windproof board was studied though experiment. The experimental study have revealed that each cathode discharging capability was weakened by the influence of windproof board which has the same voltage with cathode. The breakthrough voltage was decreased when the windproof board increase to a certain width. It discovered that wind-proof board has function of avoiding scour by gas flow though simulation precipitator's passway using two dimensions k-εequation. All these can strengthen encollecting electropositive ion dust, minishing the lost of second blowing dust and improve efficiency of electrostatic precipitator theoretically.
