듀얼 사이클론 필터를 이용한 초미세먼지 입자 유동제어

초록

The ultrafine dust removal vehicle has been recently developed to remove accumulated dust particles in railway tunnels. In order to remove the ultrafine particles as well as various size of particles, the vehicle requires prefilter system. In this paper, a dual cyclone type prefilter, therefore, was designed and applied as a new type of prefilter of the ultrafine dust removal vehicle, and its efficiency was verified through CFD analysis and design flow control. When the dual cyclone filter was applied, efficiency and maintainability has been improved as compared with the conventional mesh-typed prefilter. In addition, by efficiently collecting inhaled particles within 1.4 seconds, it is possible to reduce the load on the electric precipitator at the rear end, thereby improving the dust collecting efficiency of the dust collecting vehicle as a whole.
