窑尾脱硝降氮改造措施的应用

在水泥企业产能过剩、生产成本居高不下的情况下,水泥企业面临氮氧化物减排的巨大压力,使用的脱硝氨水用量大,且存在氨逃逸风险造成二次环境污染。分析了脱硝系统工艺流程、NO;产生的机理、氨水消耗高的原因分析、通过企业技术革新措施的应用,从而实现降低氮氧化物和节省氨水的效果。

Application of transformation measures for denitrification and nitrogen reduction at kiln tail

In the condition of overcapacity and high production costs,cement enterprises are facing great pressure on NO;emission reduction,use a large amount of denitration ammonia,and there is a risk of ammonia escape,resulting in secondary environmental pollution.The process flow of denitration system,the mechanism of NO;generation,the cause analysis of high ammonia consumption,and the application of enterprise technical innovation measures are analyzed to achieve the effect of reducing nitrogen oxides and saving ammonia.
