Study of SO_2 Removal Using Dielectric Barrier Corona Discharge

Sun Yan-zhou

Abstract

The dielectric barrier corona discharge in a wire-cylinder reactor is studied.The discharge power is calculated using the V-q Lissajous figure.With increasing the applied voltage,the discharges change from corona to stable barrier discharge.In the stable barrier discharge stage,the amplitude of continuous discharge current reaches some mA,and the power density hundreds of mW·cm -3 .It is shown that higher voltage and larger discharge space in the stable discharge stage can improve energy utilization factor of SO 2 removal.
