选煤厂浮选尾煤和事故放水及滴漏水中的煤泥均需先进的工艺和有效的设备来加以回收,以达到充分利用国家资源、实现洗水闭路循环和保护环境的目的。为此,徐州矿务局庞庄矿洗煤一厂在唐山煤研所、沈阳矿山机器厂、洛阳矿山机器厂和江苏省煤矿设计院等单位密切配合下,应用GUD—30型无格折带过滤机与XMY340/1500—61型压滤机联合流程回收浮选尾煤,以期达到煤泥全部在厂内回收,取消厂外煤泥沉淀池和实现洗水闭路循环的目的。经过几个月来的工业性试验,取得了良好效果。现将该厂过滤压滤车间回收浮选尾煤的工艺系统及效果概述如下。 Coal preparation plant flotation tailings and accidental discharge and drip water slime requires advanced technology and effective equipment to be recycled in order to achieve full use of national resources, to achieve closed-circuit washing water and the protection of the environment. To this end, Xuzhou Coal Mining Pangzhuang coal washing plant in Tangshan Coal Research Institute, Shenyang Mining Machinery Factory, Luoyang Mining Machinery Factory and Jiangsu Coal Mining Design Institute and other units in close cooperation with the application of GUD-30-type filter with no grid Machine and XMY340 / 1500-61 filter press recovery flotation tailings coal joint process, in order to achieve all of the slime in the plant recovery, abolition of slime sedimentation tank outside the factory and achieve the purpose of closed loop washing water. After several months of industrial tests, and achieved good results. Now the plant filter press plant recovery flotation tailings technology systems and results outlined below.
