超高温除尘技术在水泥行业应用的探讨

Discussion on Application of Ultra-high Temperature Dust Removal Technology in Cement Industry

简述了水泥行业高温烟气处理现状及高温除尘技术,讨论了在保证系统稳定可靠运行的前提下,进行窑头电除尘器改造的情况,也讨论了针对窑尾SCR脱硝,在余热锅炉之前,增加高温除尘器和SCR反应器的工艺改造方案,通过改造,可解决窑头面临的除尘器烧袋风险和余热锅炉磨损问题,也可解决窑尾SCR技术应用受限问题。

The present situation of high temperature flue gas treatment and high temperature dust removal technology in cement industry are briefly described.On the premise of ensuring stable and reliable operation of the system,the renovation of cooler electrostatic precipitator is discussed,as well as the programme that the SCR reactor for preheater is located before the waste heat boiler,the high temperature dust collector and SCR reactor are added.Through modification,the problems of bag burning risk of dust collector and wear of waste heat boiler at cooler can be solved,and the application limitation of SCR technology at preheater can also be solved.
