旋滤组合移动式颗粒床除尘器优化设计建模

以旋滤组合移动式颗粒床除尘器的性能-结构关系为基础,建立移动式颗粒床除尘器优化设计的数学模型。该模型以除尘效率最大为优化目标,以结构参数与运行参数间的关系为约束条件,对特定的粉尘和含尘气体以及一定的运行参数而言,优化设计变量为移动式颗粒床除尘器的结构参数(主要有进气口尺寸,旋风体直径,过滤床直径、厚度及有效过滤高度),从而确定移动式颗粒床除尘器的最佳结构尺寸。通过设计实例检验,证明了该模型具有较好的实际应用价值。

Modeling for the Optimum Design of Cyclone-filtrating Removable Grain Bed Dust Collector

Based on the relation between the performance and the structure of cyelone-filtrating removable grain bed dust collector, a mathematical model of a removable grain bed dust collector, with constraint condition of the relation between the operation parameters and structure parameters, is developed for the optimum design of highest dust-collection efficiency. For given dust, dust-contalned gas and specific operational parameters, the structure parameters, such as inlet size, diameter of cyclone device, diameter, thickness and effective height of filtrating bed, can be optimized as variables, thereby the optimal structure size of the removable grain bed dust collector is decided, mustrafion shows that such model is of great value in application.
