Axial Flow Cyclones

In Axial Flow Cyclones, also known as straight-through-flow cyclones, the inlet gas is introduced down the axis of the cyclone, with centrifugal motion being imparted by permanent vanes called swirl vanes at the top.

Particles are forced to the wall by centrifugal force and then fall down the wall due to gravity. The inner vortex of air leaves at the bottom (rather than reversing direction).

The straight-through-flow cyclone can be arranged as a single cyclone separator or as bank of similar cyclone separators (the multiclone).
