Design of a Simple Gas and Solid Filtration Apparatus

Abstract

The results of experiments using needle-bonded polypropylene fibers as filter fabrics show that the air permeability of the filter fabrics depends on the type and size of needles used for fabric construction. For dust filtration, the internal structure of the filter fabrics has an effect on the resultant collection capacity based on the air permeability. A new gas and dust filtration apparatus was designed for the investigation, and the results obtained are reproducible. A regression analysis produced high correlations between pressure drop and air flow rates, which are statistically valid at a significance level of 0.1%.
