Development and experiment of high efficiency gradient filter based on inverse problem solving method

Abstract

Abstract In order to design the gradient filter for indoor air purification accurately and quickly, an inverse problem design method was proposed, and the best gradient filter meeting the design requirements was developed. The filtration performance test of the gradient filter was carried out, and the test results meet the design target value. The theoretical calculation values and test values of filtration efficiency and resistance are compared and analyzed. It is found that their theoretical calculation values and test values are within the normal deviation range, which verifies the feasibility and correctness of the inverse problem solving method.
