本文报道了低温等离子体脱除NO/Subx/脱除NOx的实验室实验结果。在干式等离子体反应器和几个湿式反应器上进行了脱氮效率的研究。电抗器的几何结构是同轴的，内部放电电极和外部接地电极包裹在绝缘玻璃管上。实验中使用的是模拟烟气。在模拟气体中加入氨和水蒸气后，干式反应器的性能更好。在湿式反应器中，水和氢氧化钠溶液作为吸收剂，每种情况下的脱氮率都是相同的。以水为吸收剂，pH值降至3以下时，湿式反应器的性能保持不变。对湿式反应器的研究进一步表明，被等离子体去除的NO中约有一半被解离为N/sub2/和O/sub2/，其余的被水吸收。研究表明，湿式反应器比干式反应器对NO/subx/的脱除效果更好。
In this paper, the authors report the results of laboratory experiments on NO/sub x/ removal (DeNOx) using a nonthermal plasma process. Studies were conducted on a dry-type plasma reactor and several wet-type reactors to evaluate DeNOx efficiency. The reactor geometry was coaxial with an inner discharge electrode and an outer ground electrode wrapped on an insulating glass tube. Simulated flue gas was used in the experiment. The dry-type reactor performed better with the addition of ammonia and water vapor to the simulated gas. In the wet-type reactors, water and NaOH solution were used as absorbents and DeNOx performance was found to be the same in each case. Also, with water as the absorbent and with its pH value dropping below 3, the performance of the wet-type reactors remained constant. Studies on wet-type reactors, further, suggested that about half of NO removed by the plasma was dissociated into N/sub 2/ and O/sub 2/ and the rest was absorbed by water. The studies indicate that wet-type reactors performed better than the dry-type reactor in the removal of NO/sub x/.
