摘要
Filtration resistance and efficiency are the key properties of glass fiber air filter media.In practice,various fibers are combined to optimize the contradiction of filtration resistance and efficiency.For studying high performance filter media,it’s of great importance to predict the filtration resistance.The theoretical calculations are mainly confined to the ideal filter media constituted by only one kind of fiber.This paper aims at multi-component glass fiber filter media,and filtration resistance is calculated theoretically using specific surface area of different glass fibers by Kozeny-Carman Equation.The theoretical filtration resistance is very close to the experimental results with correlation coefficient R2 =0.9969.It will definitely benefit the optimal design of filter media.
