Analytical Modelling of Cyclone Separator as a Diesel Soot Particulate Filter with Inner and Outer Vortex Effect

摘要

The reduction of particulate emissions from diesel engine is one of the most challenging problems associated with the exhaust pollution control. Diesel Particulate Filters (DPF) hold out the prospects of substantially reducing regulated particulate emissions but the question of the reliable regeneration of filters still remains a difficult hurdle to be solved. Many of the solutions proposed to date suffer from design complexity, cost, regeneration problem and energy demands. Cyclone separator being a non-contact type particulate removal system exerts less back pressure to the diesel engine combustion. Very few studies have been done on cyclone separator as a diesel soot particulate filter. Cyclone separator with low initial cost, simple construction gives high collection efficiencies and reduced regeneration problems. This paper presents an improved computer aided analytical approach for controlling diesel soot particulate matter considering the outer vortex and inner vortex of cyclone. The result shows good agreements with existing cyclone and DPF flow characteristics.
