摘要
本文介绍一种在动态过滤机中,以玻璃球层作为滤饼层的模型,通过颗粒层表面粒子的力平衡,用有槽与无槽的旋转圆盘研究渗滤情况下球形固体颗粒剥落的临界牵引速度,从而研究滤饼剥落机理的方法。
By using rotating ungrooved and grooveddisks,this paper introduces a study method ofsweeping mechanism of filter cake in dynamicfiltration in which a glass ball bed is regardedas the filter cake model.The ctirical tractivevelocity of the rotating disk is determined onthe basis of the force balance for a particle inthe upper most layer of the bed.
