煤泥水药剂添加的技术改进

Technical improvement of adding slime water reagent

针对金鸡岩洗选厂入洗原煤煤质变化较大、灰分和硫分超标等问题,通过对药剂(聚丙烯酰胺)的优化选型、加药系统的技术改进及加药制度的调整,实现了闭路循环清水洗煤和药剂成本降低的目标。

Based on problems such as rather large change of raw coal quality and super-standard ash and sulfur content in coal,the target of washing coal with clear water in closed circulation and decreasing reagent cost is realized by means of optimization selecting type of reagent（polyacrylamide）,technical improvement of dosing system and adjustment of dosing regulations.
