衝突板に不織布を用いたインパクタのオイルミストの除去性能 Oil Mist Collection Performance of Impactor with Impaction Plate Covered with Unwoven Fabrics
Collection performance of impactor with impaction plate covered with various unwoven fabrics was experimentally studied by using oil mist particles. As a result, it was found that (1) application of high-porosity unwoven fabrics on impaction plate drastically raises the collection efficiency and reduces the 50% cut-off size although it degrades the classification performance, (2) 50% cut-off diameter of impactor with unwoven fabrics is insensitive to the nozzle air velocity, V<SUB>n</SUB>, and the nozzle diameter, W, and it is as small as 1 μm for 15 < V<SUB>n</SUB> < 40 m/s at W = 4. 7 mm, (3) If the pressure drop of a fabric is equal to that of an impactor, the collection efficiency of impactor with the fabric is the same as the filtration efficiency of the fabric.
