摘要
探讨了自由基与非平衡等离子体脱硝过程中自由基的产生机制及反应过程;综述了氨气、湿空气、碳氢化合物3种自由基源物质的脱硝反应机理,分析了自由基源物质对脱硝反应产物及脱硝效果的影响;指出了提高自由基源物质的转化利用率、降低脱硝反应的能耗、完善自由基在NOx转化过程中的作用机理是今后自由基与非平衡等离子体脱硝技术研究的方向。
The creation mechanism and reaction process of free radicals in denitration process using free radicals and non-equilibrium plasma were discussed. The denitration reaction mechanisms of 3 kinds of free radical sources such as NH3, humid air, hydrocarbon were summarized. The effects of different free radical sources on products and denitration efficiency were also analyzed. The direction for research on denitration process using free radicals and non-equilibrium plasma were pointed out, such as increasing the transformation ratio and utilization ratio of free radical sources, decreasing the energy consumption of denitration reaction and perfecting the function and mechanism of free radicals in NOx conversion process.
