电石渣浆过滤工艺的改进设计

Carbide slag slurry filtering process improvement design

阐述了溶解乙炔生产过程中产生的电石渣浆的压滤工艺，针对压滤工艺存在的弊端，提出经初级沉淀后加入一定量的凝结剂，通过改进后的过滤工艺，分离出清水，返回生产系统循环利用，干渣形成含水量约30％～40％的半干电石渣，直接用于生产免烧砖。达到节能降耗、三废综合利用的目的。

Abstyact： This paper expounds the dissolved acetylene production process of carbide slag slurry pressure filter technology, in view of the disadvantages of pressure filtration process, put forward the primary precipitation add a certain amount of coagulant, through the improved filtering process, separating out water and return the production system recycling, dry slag formation water content about 30% - 40% of the half dry carbide slag, directly for the production of baking-free brick. Achieve saving energy and reducing consumption, and ＂three wastes＂ the purpose of comprehensive utilization.
