摘要
随着人们对NOx危害的逐步认识,脱除氮氧化物已成为当前紧迫的任务。尿素作为脱硝还原剂,具有易运输储存、安全可靠、运行成本低等优势,将在烟气脱硝中大显身手。文章介绍了烟气脱硝技术及其还原剂的选择,尿素制氨的方法,尿素法SCR烟气脱硝技术的工艺流程、技术特点和应用前景。
Pick to along with the people about the danger of NOx, step by step removal has become a pressing task at present. As the denitration reduetant with the advantages in easy transportation, storage, safe and reliable, low operation cost, urea will play an important role in the flue gas denitration. Flue gas denitration technique and the choice of the reducing agent, urea ammonia method, the method of urea SCR flue gas denitration technology of process flow, technical features and application prospect are introduced in this paper.
