目前等离子体脱硝方法存在等离子源体积庞大、能耗高、脱硝率低，需依靠传统脱硝方法协同作用等问题。基于此，本文采用小流量高浓度等离子体注入烟道中，并与烟气中H2O反应生成·OH；在无吸收剂、无催化剂及没有其它方法协同作用下，实现了在烟道中快速氧化脱除烟气量中NOx并生成资源物质酸的反应过程，当气体温度为30℃，等离子体与NO摩尔比为2时，脱硝率达到86.8%。本方法解决了目前脱硝存在的问题，为大气污染治理提供一种绿色新方法。

At present, the plasma denitration method has some drawbacks such as large dimension of plasma source, high energy consumption, and low denitri-fication rate, which needs synergistic effect of traditional denitration methods. In this paper, a smal flow of high concentration plasma were injected into the gas flue, which reacted with H2O in the gas to form ·OH. Then the NOx in flue gas were rapidly oxidized, removed and form the material resource acid in the flue, without the absorbent, catalyst and coordination with other technologies. While the gas temperature was 30℃, and the molar ratio of plasma and NO was 2, the denitrification rate could reach 86.8%. As a result, the method solves the problems of present denitration methods, providing a new green method for air pol ution control.
