Sci-tech Cyclonic Separation Trainer Model Env 001

Sci-tech Cyclonic Separation Trainer Model ENV 001 is a method of removing particulates from an air stream through a vortex separation process. A high speed forced vortex rotating air flow is established within a cylinder called a cyclone. Cyclones are used widely in sawmills to remove saw dust from extracted air as well as oil refineries to separate oils and gases. This Cyclone Separation Trainer is used for demonstrating the basics of cyclonic vortex separation. The apparatus comprises of four main cyclones of different diameters, a dust feed system and an air supply blower. A venturi type flow meter is provided to measure the incoming air flow rates. Each cyclone is fitted with a particle collector for dust collection. Cyclones can be run individually or in series of any two. Air flow rates can be varied by controlling the air blower speed. A dust tank is provided to inject the dust into the system. Differential pressure measurement for individual cyclones is provided to measure the pressure drop across the cyclone and hence the velocity of air in the cyclone can be determined.

Sci-tech Cyclonic Separation Trainer Model ENV 001 trainer consists of three cyclone separators mounted on frame. Two cyclone separators are made of steel & one is made of glass. The cyclones can be arranged in such way that either one cyclone can be operated at a time, or two cyclones can be operated in series. A high-volume air blower which draws large volume of air through the cyclone separator. A hopper with control valve is used to feed dust particles into the stream of air. The air mixed with particles then enters tangentially at the top inlet in the separator. The dust particles are separated in the separator & collected in container at the bottom. The filtered air leaves the separator through the outlet at the top. A Variable Speed Drive is used to vary the velocity & flow of air through the separator.

Each cyclone separator has glands to for measuring pressure difference across the cyclone. A differential pressure gauge is used to measure the differential pressure across cyclone. The air flow is measured by a venturi meter with differential pressure gauge.
