Reverse-Flow Cyclones Demister can be subdivided in two categories: tangential inlet and axial inlet.
In a reverse-flow cyclone demister with tangential inlet, the dirty gas enters at the top of the cyclone and is given a spinning motion because of its tangential entry.
Mist particles are forced to the wall by centrifugal force, coalesce and then fall down the wall due to gravity. At the bottom of the cyclone the gas flow reverses to form an inner core that leaves at the top of the unit.
In a reverse-flow cyclone demister with axial-inlet cyclone, the inlet gas is introduced down the axis of the cyclone, with centrifugal motion being imparted by permanent curved blades at the top.
Mist Particles are forced to the wall by centrifugal force, coalesce and then fall down the wall due to gravity. At the bottom of the cyclone the gas flow reverses to form an inner core that leaves at the top of the unit.
The reverse-flow cyclones demister can be arranged as a single cyclone separator or as bank of similar cyclone separators in parallel (the multicyclone).
