水对电晕放电脱硫脱硝影响的研究

依据等离子体理论，研制了水膜式电晕放电试验模型，在不同电压下，对不同体积分数的SO2和NOx烟气的电晕放电形成机理进行了研究。实验结果表明：由于水的存在，高压电极与水膜之间的电晕放电所形成的离子风增强了烟气净化效果，脱硫、脱氮率分别达到95％和80％，这对酸雨的防治和烟气的处理以及对传统的电除尘设备的改进具有重要的意义。

Influence of Water on Corona Discharge in Flue Gas

In this paper a novel type of a water film corona discharge experiment model is designed. The reactor is composed of needle-plate electrodes that are placed in a glass container filled with the flue gas, (the plate electrode is immersed in the water). The mechanism of the formation of corona discharge in the pollution flue gas containing dust, sulfur dioxide (SO_2) and nitrogen oxides (NO_x) is investigated under the conditions that there are different concentration of sulfur dioxide and nitrogen oxides of the flue gas and different applying voltages. Based on this it is emphasized on studying the influence of water on corona discharge in flue gas. The experimental results show that the corona wind forming between high-voltage electrode and water film by corona discharge enhances the cleaning efficiency of the flue gas because of the existence of the water film, and the cleaning efficiency up to 95% and 80% of SO_2 and NO_x removal respectively under suitable conditions. This project is very significant for the prevention of acid rain and the treatment of dust of flue gas and the improvement on the traditional electrical dust precipitator.
