The article from the perspective of the design process by filtering dust removal mechanism,estimates of the inertial filter in the filter capture efficiency,the efficiency of Brownian diffusion,direct interception efficiency and a variety of effects that can be drawn to the combined effect of the total filtration efficiency,based on pressure lower estimates of stainless steel sintered metal fiber felt filter accuracy and service life,ensuring the use of filters provides a theoretical basis.%文章从工艺设计的角度通过过滤除尘机理,测算了滤料中过滤器的惯性捕捉效率、布朗扩散效率、直接拦截效率以及各种效应的联合效应得出所能达到的过滤总效率,根据压降测算出不锈钢烧结金属纤维毡的过滤精度和使用寿命,保证过滤器的使用提供了理论依据。
