A n Cyclone separator stationary mechanical device that utilizes centrifugal force to separate solid or liquid particles from a carrier gas . Cyclones have no moving parts and available in many shapes and sizes, for example from the small 1 and 2 cm diameter source sampling cyclones which are used for particle size analysis to the large 5 m diameter cyclone separators used after wet scrubbers. What it is…
Lets make things a bit c l e a r … Vortex Finder Tangential inlet duct Bar r el Cone Dust Collector
The flow enters near the top through the tangential inlet, which gives rise to an axially descending spiral of gas and a centrifugal force field that causes the incoming particles to concentrate along, and spiral down, the inner walls of the cyclone separator. Working Principle The collected particulates are allowed to exit out an underflow pipe while the gas phase reverses its axial direction of flow and exits out through the vortex finder (gas outlet tube) .
Design Parameters a = inlet height b = inlet width Dx = vortex finder diameter Ht = total height of cyclone h = cylinder height S = Vortex finder diameter Bc = cone tip diameter

Advantages 3. T he collected product remains dry and, normally useful. 4. L ow capital investment and maintenance costs in most applications . 5. C an be used under extreme processing conditions no moving parts . 1. C an, in some processes, handle sticky or tacky solids with proper liquid irrigation. 2. C an separate either solids or liquid particulates; sometimes both. Disadvantages low efficiency for particle sizes below their ‘cut-off diameter when operated under low solids- loading conditions. usually higher pressure loss than other separator types. subject to erosive wear and fouling if solids being processed are abrasive or ‘sticky.
