The Experimental Research of NO Removal by Dielectric Barrier Discharge at Atmospheric Pressure

摘要

A set of experimental set-up of coaxial cylinder-tube dielectric barrier discharge reactor is designed to investigate NO removal with non-thermal plasma produced by barrier discharges. Experimental results show that the method is effective. The influences of length of the discharge region, the discharge gap, the amplitude and frequency of applied voltage on the NO removal rate are also investigated respectively. The results show that removal rate of NO increased with increasing length of the discharge region and the power voltage. As discharge gap and power frequency increasing, the removal rate of NO increases first and then decreases.
