Patent ID: 7279020

Claim:
An axial flowing droplet catching demisting cyclone for the separation of a mixture of gas and liquid, comprising an inlet ( 30 ) for gas which contains liquid droplets, and an outlet ( 31 ) for substantially dry gas, a generally cylindrical cyclone tube ( 16 ) which includes at least one patch of slots or perforations ( 19 ) to allow part of the fluid including separated liquid to flow out of the cyclone tube ( 16 ), and a swirl inducing member ( 17 , 18 ) for inducing swirl on the incoming fluid; the improvement comprising, the swirl inducing member (l 7 , 18 ) comprises a cascade of vanes which are attached to a generally cylindrical core body and which extend outwardly therefrom toward the inner wall of the cyclone tube ( 16 ), said vanes being cambered in the longitudinal direction from the leading edge ( 23 ) to the trailing edge ( 24 ), and said vanes having a shape that promotes a rotational velocity component that increases when moving in the radial direction from the inner wall of the cyclone tube ( 16 ) toward the outer wall of the core body.
