| 中文摘要: |
| 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、NOx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。 |
| 英文摘要: |
| In the condition of overcapacity and high production costs, cement enterprises are facing great pressure on NOx 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 NOx 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. |
