Multi cyclone dust collector & Multi cyclone separator works on the same principle as single cyclone dust collector using inertia & Centrifugal force forming dual vortex to separate heavier dusts from dust laden gas. The efficiency of a cyclone seperators in collecting finer dusts is highly depends on the amount of centrifugal forces created and longer residence time to allow more dusts to settle down. These two factors increases better separation of particles. The centrifugal force can be increased by reducing the cyclone diameter and the residence time can be increased by increasing the cone height. To match with airflow requirements and optimal pressure drop, large number of thinner and longer cyclones are arranged in parallel and combining all inlets in to one common inlet and all outlets into one common outlets. The pressure drop of Multicyclone is comparably higher than a single cyclones of same CFM but this higher pressure drop yields higher efficiency.
