摘要
NOx是形成酸雨的主要污染物之一,根据国家要求必须减少NOx排放量。本文综述了湿法脱硝技术和干法脱硝技术的研究现状,对碱液吸收法、氧化吸收法、还原吸收法、络合吸收法、液相催化法、SCR和SNCR脱硝技术的脱硝率、原理和优缺点进行了评述,并对烟气脱硝技术的发展方向进行了展望。
NOx is one of the main pollutants leading to acid rain and it must be reduced according to state requirement. In this paper,the present situations of wet denitration technology and dry were summarized. The denitration rate,principles,merits and demerits of alkali absorption method,the oxidation absorption method,the reduction absorption method,the complex absorption method,the liquid phase catalysis method,SCR and SNCR,were introduced. Then,the paper finally looks into the future of denitration technologies.
