Abstract

The main purpose of this study is to investigate the collection characteristics of multi-layer multi-stage porous plate system with impaction effect, experimentally. The experiment is carried out to analyze the characteristics of pressure drop and collection efficiency for the present system with the experimental parameters such as inlet velocity, tube diameter, stage number and multi-layer porous plate array, etc. In results, the collection efficiency becomes higher 65.31 to 94.27% with increment of stage number of multi-layer porous plate system (1 to 5 stages), while the gradient of increment of collection efficiency is to be lower. Additionally, it is estimated that with increment of stage number(1 to 5 stage) at inlet velocity v_(s, in)(= 0.92 ㎧ and plate arrangement [8, 8, 8, 8, 8 mm], the pressure drop becomes much higher as 17, 27, 41, 62 and 82 mmH₂O, respectively. The 5 stage multi-layer porous plate system of [10, 6, 10, 10, 10 mm] changed partially to 6 mm tube diameter, represents the higher collection efficiency over 96% for overall range but the pressure drop increases with 148 mmH₂O.
