水泥窑协同处置村镇生活垃圾的一种新模式

A new co-processing model for township domestic waste in the cement kiln system

通过对广西村镇生活垃圾特点的分析,结合水泥窑处置生活垃圾技术现状,提出了一种将村镇生活垃圾进行一定处理,然后随三次风直接喷入分解炉的水泥窑协同处置新模式。试验表明:80 t/d的掺烧范围内,用该模式处置村镇生活垃圾对水泥窑工况、水泥熟料品质以及窑尾污染物排放的影响不明显,处置效果可以达到"减量化、无害化、资源化"的目标,并且工艺简单、投资成本低,为村镇生活垃圾的处置提供了一条新途径。

Based on the analysis of domestic waste features of towns and villages in Guangxi, and present situation of disposal technology using NSP （ new suspension preheater） kiln, a new model was put forward. The domestic waste was sprayed into preheater with the tertiary air after a simple preprocessing. The experiment results showed that： there was no obvious effect on the operation of kiln, the quality of clinker and the emission of pollutants from the stack with this new model when the co-incinerating quantity was within the limits of 80 t/d. At the same time, the goal,“reduction, harmless, resources”, was achieved. It also was of the advantages of simple process, low cost and thus provides a new approach for the disposal of domestic waste.
