摘要
为了研究煤矿矿井水污泥离心脱水性能,预测现场污泥离心脱水的效果,试验分析了离心分离因素(Z)、分离时间(t)对污泥浓度(S)的影响,构建了S-lg Zkt曲线。结果表明,对于煤矿矿井水污泥S与lg Zkt具有线性相关性;k=1.8时拟合度最高,煤矿矿井水污泥离心脱水性能可用S=c+alg Z1.8t表示;其中c、a是表示污泥性质的参数,可以通过试验确定;该曲线方程可用于离心脱水机选型或预测现场离心脱水效果。
In order to research the centrifugal dewatering property of coal mine water sludge,and predict the effect of centrifugal dewatering on the field, the influence of centrifugal separation factor（Z） and separation time（t） on sludge concentration（S） were analyzed by experiment, S-lg Z^kt curves were constructed. The results show that the S has linear correlation in coal mine water sludge with lg Z^kt. The fitting degree is the highest when k =1.8, the centrifugal performance of coal mine water sludge should be expressed by S =c ＋alg Z^1.8t, the sludge property parameters of ca can be determined by experiment. The curve equation can be used for selection of centrifugal dewatering machine and prediction the effect of centrifugal dewatering at plant.
