Abstract:
1. A method for separating liquid or particulate from a flowing gas stream comprising the following steps: receiving a gas stream containing liquid or particulate; directing the gas stream through a plurality of helical flow paths having a generally vertical central axis, the helical gas flow paths forming secondary vortices with approximately equal axial and tangential flow velocities; forming a vortex core in a generally conical cavity located beneath the helical gas flow paths, the vortex core directing liquid or particulate outwardly toward a generally vertical outer tube by centrifugal force; forming a toroidal vortex ring in an annular space between the outer tube and a generally vertical inner tube that is axially aligned below the helical gas flow paths; wherein the liquid or particulate separated from the gas is directed by the toroidal vortex ring toward the outer tube, and the gas separated from the liquid or particulate flows through the inner tube.
