Tail gas ammonia-free denitration method and device in cement kiln production
The invention discloses a tail gas ammonia-free denitration method and device in cement kiln production. The tail gas ammonia-free denitration device is communicated with a rotary kiln. The tail gas ammonia-free denitration device comprises a decomposing furnace, a tertiary air pipe and a smoke chamber. The device further comprises a gasification furnace and a mixing chamber. The gasification furnace is in a U shape and comprises a furnace body A, a furnace body B and a gooseneck pipe. The head of the furnace body A is communicated with the head of the furnace body B through the gooseneck pipe. According to the invention, by using a reduction furnace, the reduction area of nitrogen oxide is increased, the reduction reaction of NOx in the reduction furnace is promoted, the emission of Nox is further reduced, and the required emission amount is achieved. The reduction furnace is used, so that ammonia water is prevented from being used for denitration, environmental pollution is further reduced, and environmental friendliness is achieved.
本发明公开了水泥窑生产中尾气无氨脱硝方法及装置，尾气无氨脱硝装置与回转窑连通；尾气无氨脱硝装置包括分解炉、三次风管、烟室；还包括气化炉、混合室；气化炉为U型，包括炉体A、炉体B、鹅颈管：炉体A与炉体B的头部通过鹅颈管连通。本发明通过使用还原炉，增加了氮氧化物的还原区，促进NOx在还原炉中发生还原反应，进一步降低Nox的排放，达到所要求的排放量；使用还原炉，避免了使用氨水来进行脱硝，更进一步的减少了对环境的污染，对环境友好。
