| 摘 要： | 建立烧结金属丝网过滤器的二维结构模型,定义了多孔介质边界条件,利用Fluent6.1对过滤元件内的二维气体流动进行数学模拟计算。由此分析了丝网过滤体内的过滤状况,阐述了烧结金属丝网过滤除尘机理,将过滤过程分为4个阶段;分析了过滤参数等对过滤压降的影响。为金属丝网过滤器的设计和优化提供了一定的参考依据。

| Abstract: | Based on structure model of a Sintered Metal Mesh Filter (SMMF), a two-dimensional flow model in which the boundary conditions of porous medium are defined is established, and calculated by Fluent6.1. The condition of filtration in SMMF is analyzed, at the same time, the mechanism of filtration and the effects of parameters of filtration on the pressure drop are discussed. This article provides a reference to optimize the filter. |
