Abstract : Cyclone, a type of particle collector widely used in the field of ambient sampling and industrial particulate control, is the principal type
of gas-solids separator that use a centrifugal force. The goal of this study is to transform conventional cyclone into a new type of cyclone
that can be used for the household vacuum cleaners. To meet the goal, first, the analysis about local environment and dust is carried out.
Second, it must have enough high-efficiency not to reduce suction power due to clogging of exhaust filter unit. Two single cyclones with
central-hopper-dust-outlet and side-wall-dust-outlet and a twin cyclone are designed and fabricated to evaluate, and compare, their dust
collection efficiencies and pressure drops. The measurements of separation efficiency for dust by using DMT test dust type 08 are carried
out. House dust experiment is additionally performed to check the local matters applicability such as tissue papers, fur and hairs. The
collection efficiency of the twin cyclone is found to be 3-6% greater than those of two single cyclones with the same body diameter, inlet
and inner cylinder diameter. Twin cyclone with a large body diameter, a small inner cylinder diameter, a short inner cylinder, a narrow
inlet has high separation efficiency. This result indicates the possibility of achieving higher collection efficiencies with a twin cyclone.
