高硫洗选尾矸综合利用工艺改进的研究

Research of improving high sulfur washed refuse and tailing comprehensive utilization process

针对传统三产品重介选煤工艺和高硫洗矸脱硫生产工艺存在的主要问题,提出采用大锥角重介旋流器分选工艺改造二段中矸分选旋流器,增加煤炭回收率,减少高硫洗矸处理量,降低高硫洗矸脱硫加工生产运行成本,提高企业经济效益。

From existence main question of using the traditional three products heavy-medium cyclone to wash coal and process high sulfur washed refuse, proposed the big cone angle heavy-medium cyclone process changing into using the second heavy-medium cyclone to dispose middle and refuse, increases coal returns-ratio, reduces high sulfur washed refuse capacity, reduces high sulfur washed refuse process and operation cost, enhances the enterprise economic efficiency.
