水泥行业降氮脱硝措施及工程应用浅析

摘要

Cement industry is the second largest nitrogen oxides( NOx )emission source of China's industrial enterprise. NOx emissions control is the key for energy saving and emission reduction during the "12th Five - Year Plan" period. The implementa- tion of denitrification policy and promotion of discharge standards will reduce the NOx emission. Through reviews on common deni- gration technologies and comparison of their applications, this paper briefly analyzed the status of NOx emissions from cement in- dustry. Results show that it is feasible and urgent to enhance the NOx emission standards in cement industry. Some proposals in the application of denigration technology were put forward.%水泥行业是中国工业企业中第二大氮氧化物排放源,对水泥行业进行氮氧化物控制是中国＂十二五＂节能减排工作的重点,实施强制脱硝政策和提高排放标准有利于水泥行业减少氮氧化物排放。通过综述几种常用脱硝技术的原理和应用比较,简要分析中国当前水泥行业氮氧化物排放现状,得出提高水泥行业氮氧化物排放标准的可行性和迫切性,同时对脱硝技术应用提出建议。
