Abstract
Abstract A system for separating an entrained liquid component from a gas stream employing at least one vortex tube having a liquid outlet end and a wet gas inlet tangential to its sidewall and arranged so that wet gas rotates within the vortex tube to cause the liquid components to be forced against the interior wall surface by centrifugal action. An orifice plate closing the vortex tube first end has a concentric gas outlet opening therein. A vortex finder tube extends concentrically within the vortex tube providing an annular area between itself and the vortex tube internal wall. A gas deflector positioned within the annular area has a downwardly spiraled surface that diverts wet gas downwardly away from the wet gas inlet. In one embodiment, an outlet tube is affixed to the orifice plate central opening and is configured to divert outlet gas downwardly. In another embodiment, an energy absorbing housing surrounds the vortex tube liquid outlet end.
