초록

In this work, the effects of space charge was analyzed in removal efficiency of pollutant using dielectric barrier discharges. In order to investigate effects of space charge, two dielectrics(XLPE and TR-XLPE) was chosen which are different in space charge distribution. The simultaneously measurement of space charge and discharge current was carried out in XLPE and TR-XLPE with air gap by Pulsed-Electro-Acoustic Method in ac. Also, the removal efficiency is measured by classical ozone generator(von Siemens 1875). From the experimental results, we knew that the space charge distribution affects the discharge patterns. The more space charge is in surface, the quickly discharge initiates and the magnitude of discharge is increased when polarity changes. And these affect the removal efficiency of pollutant.
