摘要
NO x是空气污染因子之一,国家对烟气中NO x的排放控制越来越严格,不仅对排放烟气中NO x的浓度有要求,对排放总量亦有要求。本文对烟气湿法脱硝技术和烟气干法脱硝技术的研究进展进行了综述,简述了酸液吸收法、碱液吸收法、氧化吸收法、络合吸收法、微生物法、选择性催化还原法、选择性非催化还原法等方法的基本原理、优缺点和研究现状,并对烟气脱硝技术的发展方向进行了展望。
NO x is one of the air pollution factors.The national emission control of NO x in flue gas is becoming more and more stringent.There are requirements not only for the concentration of NO x in flue gas,but also for the total emission.The research progress on wet flue gas denitrification technology and dry flue gas denitrification technology was reviewed.The basic principles,advantages and disadvantages of acid absorption method,alkali absorption method,oxidation absorption method,complex absorption method,microbial method,selective catalytic reduction method and selective non-catalytic reduction method were briefly described.The development trend of flue gas denitrification technology was also prospected.
