Determination of the Patterns in the Formation of Gas Filter Cartridge Geometries

Abstract

The optimal geometric dimensions and dependencies for gas mask filter boxes have been determined. The geometric dimensions of the filter boxes have been defined using comfort, performance, and efficiency coefficients. These coefficients have been established through computer modeling of airflow movement within gas mask filter boxes using the SolidWorks software. The base models for creating digital copies were two types of filter boxes: cylindrical and flat, which differed in their geometric dimensions. The relationships between comfort, efficiency, and performance of gas mask filters have been determined, depending on airflow resistance, filter volume and surface area, protection duration, and the geometric dimensions of the filter boxes, which influence the speed and stability of the filtration process. Rational structural parameters of filter boxes (diameter and height for cylindrical filters, as well as side dimensions and height for flat filters) have been established by comparing the dependency curves of efficiency, performance, and comfort coefficients on airflow rate and the distribution of filtration velocity throughout the filter surface.
