Abstract
A new axial flow cyclone dust collector was developed as the intake hood for functioning as an air cleaner in a house ventilation system. Filter maintenance poses a problem in ordinary air cleaners; however, the cyclone dust collector has no such problem. However, conventional cyclone dust collectors are not suitable as the intake hood because of their large size, long conical shape, and high pressure loss. The new developed axial flow cyclone dust collector, which is compact and has a high capture rate and low pressure loss, will be useful in solving these problems. The purpose of this study is to determine the optimum design parameters of the axial flow cyclone dust collector and verify its advantages as an intake hood in house ventilation systems. We elucidated the relationship between the design parameters of the cyclone dust collector and its performance as an intake hood for functioning as an air cleaner. The optimum design parameters, for increasing the capture rate and decreasing the pressure loss, were also shown. This cyclone intake hood works well, reducing the filter maintenance cost.
