【摘要】：基于大气压空气辉光放电等离子体技术,采用多层网状接触式电极结构在烟道中形成大面积均匀稳定的辉光放电.利用放电过程中产生的强氧化活性粒子(·OH、O、O_3)氧化脱除烟气中的SO_2和NO_x.探讨接触式电极下辉光放电等离子体的生成特性和脱硫脱硝反应机制,分析不同电极层数、氧气浓度和待处理气体初始浓度等实验条件下的烟气处理效果.结果表明,在6层网状电极,氧气浓度为8%,烟气停留时间为1.2s的实验条件下,脱硫率在96.3%以上,NO氧化率为91.2%,脱硝率为36.7%.辉光放电等离子体以其高密度的带电粒子特性在烟气处理中显示出良好的能量利用效率.
[Abstract]:Based on the atmospheric pressure air glow discharge plasma technology, a large area uniform and stable glow discharge is formed in the flue by using a multi-layer reticulated contact electrode structure. Removal of SO_2 and NO_x. from flue Gas by Oxidation of strongly oxidized active particles (OH,O,O_3) produced during discharge The formation characteristics of glow discharge plasma under contact electrode and the mechanism of desulphurization and denitrification were discussed. The effects of flue gas treatment under different electrode layers, oxygen concentration and initial concentration of gas to be treated were analyzed. The results showed that under the experimental conditions of 6 layer reticulated electrode, oxygen concentration 8% and flue gas residence time 1.2 s, the desulphurization rate was over 96.3%, the oxidation rate of NO was 91.2%, and the denitrification rate was 36.7%. Glow discharge plasma shows good energy utilization efficiency in flue gas treatment because of its high density charged particle characteristics.
