Abstract

Based on the wire-tube dielectric barrier discharge (DBD) reactor, this study investigated the effects of the materials and configurations of high-voltage pole, insulating medium layer and grounding pole on the discharge power, power factor, and ozone concentration of the reactor, respectively. The DBD reactor had the best discharge power and power factor and the highest ozone concentration when the high-voltage pole was the linear copper wire, the insulating medium material was quartz tube, and the grounding pole was the copper wire winding. Based on this optimized DBD reactor, the effect of energy density on the treatment efficiency and ozone concentration of H2S exhaust gas was further investigated. At the energy density of 2143.1 J L−1, the H2S exhaust gas treatment efficiency reached 100% and the residual ozone concentration decreased to 0 g m−3.
