基于一种优化计算方法的烧结不锈钢过滤元件设计

Design of Sintered Stainless Steel Filter Element Based on An Optimized Calculation Method

本文对烧结不锈钢过滤元件的设计全过程进行了系统的梳理,并提出了一种过滤元件校核计算的优化计算方法。首先参考《多孔介质流体动力学》[1]一书,给出了流体流动特性的判定方法,进而引入系数“有效孔隙率”,对GB/T5250-2014《可渗透烧结金属材料流体渗透性的测定》[2]中的压降计算公式进行了优化,提高了过滤元件计算的准确性,也提高了过滤元件的安全性。最终通过某项目所采用的烧结不锈钢过滤元件的计算算例,为烧结不锈钢过滤元件的设计提供了切实可行的方法。

This paper systematically combs the entire design process of sintered stainless steel filter elements,and proposes an optimization calculation method for the filter element check.Firstly,refer to the book of“Dynamics of Fluids in Porous Media”[1],the determination method of fluid characteristics is given,and the coefficient“effective porosity”is introduced to optimize the pressure drop calculation formula in GB/T5250-2014“Permeable sintered metal materials-Determination of fluid permeability”[2].Thus,The calculation accuracy of the filter element is improved,and the safety of the filter element is also improved.Finally,a calculation example of the sintered stainless steel filter element used in a project is given to provide a practical method for the design of the sintered stainless steel filter element.
