Numerical Analysis of Multi Axial-Flow Cyclone for AHU Pre-Filter in Subway Station
In Korean subway station, auto suction roll filter, auto cleaning demister and electrostatic precipitator is used as pre-filter of subway station air handling unit (AHU). These kinds of filter require high maintenance and effort. To alternate these kinds of filters, we suggest cyclone type filter. A Cyclone is widely used device which remove dust or droplet by centrifugal force. It has many advantages such as constant performance, high throughput and low maintenance cost. If it is installed in subway station AHU, maintenance and effort can be reduced. The Cyclone separator is classified into tangential-flow cyclone and axial-flow cyclone according its main flow direction. Although tangential-flow cyclone is more widely used because of high particle removal rate, it cannot be installed in subway station AHU because it needs large space. However axial-flow cyclone does not require such spaces, so it can be used as a pre-filter of subway station AHU. However compare with tangential-flow cyclone, related studies are insufficient especially for axial-flow cyclone in parallel. In this study, we evaluated new kind of pre-filter which consist of multiple axial-flow cyclones connected in parallel by computational fluid dynamics (CFD).
