The overall filtration process is viewed from a new perspective: There is a continuous, systematic change in the structure of the active deposition zone of a given filter layer, here as the so‐called active filtering layer. During the overall filtration process, the filtering layer is transformed from the initial clean filter medium, via continuous particle deposition under the given filtration conditions, to a new, dynamically preserved stable porous structure, i.e. the active deposition zone on the upstream side of the dust cake. Based on 3D simulations of cake formation on model filters for fabric filters, 1D deposition profiles during the continuous filtration process are evaluated and converted into a dimensionless form, to describe the structural changes in the filtering layer. The stable 1D deposition profile during the phase of surface filtration can be well described with a logistic function.

连续粉尘沉积过程中过滤层结构变化的一维视图——过滤过程整体视图的新方法

从一个新的角度看待整个过滤过程：给定过滤层的活性沉积区的结构发生连续的、系统的变化，这里称为活性过滤层。在整个过滤过程中，过滤层由最初洁净的过滤介质，在给定的过滤条件下，通过颗粒的连续沉积，转变为新的、动态保存的稳定的多孔结构，即粉尘上游侧的活性沉积区。蛋糕。基于织物过滤器模型过滤器上滤饼形成的 3D 模拟，评估连续过滤过程中的一维沉积剖面并将其转换为无量纲形式，以描述过滤层的结构变化。表面过滤阶段稳定的一维沉积剖面可以用逻辑函数很好地描述。
