等压滤饼过滤过程中五个基本理论问题之探讨——等压滤饼过滤过程中单位过滤面积的滤液体积与过滤时间的通用数学模型

Discussion on Five Basic Theoretical Problems of Isobaric Filter Cake inFiltration Process: General Mathematical Model of Filtrate Volume Per UnitFiltration Area and Filtration Time during Isobaric Filter Cake Filtration

简要叙述了过滤过程中,滤饼层中发生的一系列现象。提出了滤饼的分类可分为局部比阻均布滤饼与局部比阻非均布滤饼两大类,同时给出了等压滤饼过滤过程中单位过滤面积的滤液体积与过滤时间的通用数学模型。

During the filtration process, a series of phenomena occurring in the filter cake layer were briefly described. It was proposed that the classification of filter cake should be two categories: local specific resistance uniform filter cake and local specific resistance non-uniform filter cake. At the same time, the general mathematical model of the filtrate volume per unit filtration area and the filtration time was given during the filtration process of the isobaric cake.
