摘　　要：吸附法可以利用吸附剂的选择吸附作用,在常温下对废气中的NO、NO 2进行深度吸附净化,再通过升温或变压实现解吸,同时得到高浓度的资源化产品NO 2。满足烟气NO_(x)超低净化排放标准并同步实现NO 2资源化回收利用,是实现变“被动”环保为“主动”环保的技术革新。鉴于NO_(x)的净化及资源化对核工业的重要性,文中综述NO_(x)吸附净化法的进展及其存在的亟待解决的问题,结合对技术发展历程、应用前景的分析,提出未来NO_(x)吸附净化法的发展方向。The adsorption method can make use of the selective adsorption of adsorbent to deeply adsorb and purify NO and NO 2 in waste gas at room temperature.Then desorption can be achieved by temperature rise or pressure swing,and high concentration resource product NO 2 is obtained.Meeting the ultra-low purification emission standard of flue gas NO_(x)and realizing the resource recovery and utilization of NO 2 at the same time is a technological innovation to change“passive”environmental protection into“active”environmental protection.In view of the importance of NO_(x)purification and recycling to the nuclear industry,the progress of NO_(x)adsorption purification method and the existing problems to be solved were summarized.The development direction of NO_(x)adsorption purification method in the future was put forward based on the analysis of technology development and application prospect.
