选煤厂煤泥水高效过滤成套装备与控制系统设计

Design of High Efficiency Filtration Equipment and Control System for Coal Slurry Water in Coal Processing Plant

选煤厂的煤泥水中含有大量的悬浮物以及有机污染物,是一个重度污染源。为了获得可以重复利用的水,就需要对煤泥水进行过滤和沉淀,目前国内采用的煤泥水处理设备存在环保风险较大、设备故障率较高、环境污染严重等问题,严重制约了煤泥水的处理进度和效果。基于此,设计出一套选煤厂煤泥水高效过滤成套装备,并且开发了与之配套的控制和监控系统,以保证各个子系统的有序运行,实践中取得了良好的应用效果。

The coal sludge water of coal processing plant contains a large amount of suspended matter and organic pollutants,which is a heavy pollution source.In order to obtain water that can be reused,coal sludge water needs to be filtered and precipitated.The coal sludge water treatment equipment currently used in China has problems such as high environmental risks,high equipment failure rate and serious environmental pollution,which seriously restrict the progress and effectiveness of coal sludge water treatment.This paper designed a set of high efficiency filtering equipment for coal sludge water in coal processing plants,and developed a control and monitoring system to ensure the orderly operation of each subsystem,and achieved good application results.
