Improvement in the Performance by Changing Electrode Shape in Barrier Discharge Type ESP

Abstract

In general corona discharge is used in ESP (Electrostatic Precipitator). The corona discharge type ESP can remove DEP (Diesel Exhaust particles) at high collection efficiency but at low removal efficiency for NOx and re-entrainment phenomena due to low resistivity and particle agglomeration on the electrode. Barrier discharge is effective for removal NOx. Therefore, we are used Barrier discharge in ESP In this paper, we investigated the plate type, punched hole type, and grid type electrode. As results, energy efficiency of particle collection becomes high with punched hole and grid type electrode than with plate type electrode. And then, punched hole type achieved high collection efficiency as comparison with plane type electrode at the same power consumption.
