水泥窑协同处置危废中硫对生产的影响研究

Research on the influence of sulfur in hazardous waste treated by cement kiln on production

采用水泥窑协同处置工业试验,对应用水泥窑协同处置危险废物无害化处理与资源化利用进行了研究。经过预处理的危险废物作为替代燃料用于水泥熟料生产,研究表明,本试验中将质量分数1.75%硫含量危废按照2 t/h、2.5 t/h、3 t/h泵送入窑,对熟料的质量和产量基本无影响,同时SO2排放完全符合水泥工业大气污染物排放标准。

In this paper, the industrial test of cement kiln collaborative disposal is used to study the application of cement kiln collaborative disposal of hazardous waste harmless treatment and resource utilization. The pretreated hazardous waste is used as an alternative fuel for cement clinker production. The research shows that the hazardous waste with 1.75% sulfur content is pumped into the kiln according to 2 t/h, 2.5 t/h and 3 t/h,which has no effect on the quality and output of clinker, and the SO2 emission fully meets the air pollutant emission standard of water sludge industry.
