煤泥水处理药剂的探索与实践

介绍了金鸡岩洗选厂工艺流程。通过对原煤性质的分析,说明入洗煤质极度恶化,为煤泥水处理带来困难。通过对煤泥水处理药剂的实验室及工业试验研究,确定了适合煤质现状的药剂组合,使高灰细粒煤泥得到快速有效沉降,达到了降低药剂用量和提高煤泥回收率的目的。 Introduce disposing process of coal slime in Jinjiyan coal washery,find that bad quality of coal slime make it hard for flocculating.After laboratory and practical research of flocculation chemicals of coal slime,confirm the best flocculanting combination which apply to current coal slime quality.This chemicals combination could quickly dispose high-ash fine coal slime.The results show that with less flocculanting can get higher recovery efficiency
