摘要(Abstract):
为解决上湾选煤厂系统制约瓶颈,提升生产效率和产品质量,针对原煤煤质及商品煤质量变化情况,梳理生产系统各环节存在的问题,有针对性地进行系统优化。通过对原煤分级、破碎、分选、商品煤降水等环节的优化,降低块煤分选下限、产品水分、系统故障率及生产成本,提升生产效率和产品质量,达到生产效率和产品质量双提升的目的。改造后原煤分级效率由75%提升至92%,生产连续性增强,生产效率提高约2%,入选率提高约2.5%,产品质量提升0.3 MJ左右,全年可节约生产成本36万元,提质增效效果明显。
In order to solve the system restriction bottleneck of Shangwan Coal Preparation plant and improve production efficiency and product quality, according to the changes of raw coal quality and commercial coal quality, the problems existing in each link of the production system and targeted system optimization were carried out.Through the optimization of raw coal classification, crushing, sorting and commercial coal precipitation, reduce the lower limit of lump coal separation, product moisture, system failure rate and production cost, improve production efficiency and product quality, and achieve the purpose of double improvement of production efficiency and product quality.After the transformation, the classification efficiency of raw coal is increased from 75% to 92%,the production continuity is enhanced, the production efficiency is increased by about 2%,the washing rate is increased by about 2.5%,the product quality is improved by about 0.3 MJ,the annual production cost can be saved by 360 000 yuan, and the effect of quality improvement and efficiency increase is obvious.
