Abstract

A cyclone dust collector is applied in many industries. Especially the axial flow cyclone is the most simple construction and it keeps high reliability for maintenance. On the other hand, the collection efficiency of the cyclone depends not only on the inlet gas velocity but also on the feed particle concentration. The collection efficiency increases with increasing feed particle concentration. However until now the problem of how to estimate the collection efficiency depended on the feed particle concentration is remained except the investigation by Muschelknautz & Brunner[6]. Therefore in this paper one of the estimate method for the collection efficiency of the axial flow cyclones is proposed. The application to the geometrically similar type of cyclone of the body diameters D 1=30, 50, 69 and 99 mm showed in good agreement with the experimental results of the collection efficiencies which were described in detail in the paper by Ogawa & Sugiyama[8].
