摘要

用流体力学与实验观测相结合

推导出稳定动态过滤下滤饼厚度公式

指出滤饼厚度随浓度上升而增厚

且与叶轮转速同过滤半径的乘积成线性关系;给出动态过滤情况下过滤速率计算公式.各项理论关联值与试验值吻合较好

由此提出了对工业设计有指导意义的关系式.

Abstract

Based on the principles of hydrodynamics and experimental observation

a formula of cake thickness was presented. It was confirmed that the cake thickness varied not only with the product of turbine rotating velocity and the radius of filtration area

but also with the concentration of suspension. Under the condition of dynamic filtration

a formula was developed to calculate the filtration rate. The formula agreed well with the experimental results.
