Abstract
A multi-stage axial flow cyclone separator comprising a primary swirl creating section, a swirl acceleration section, and a fluid separation section is disclosed. A fluid transfer tube is mounted axially in the middle of the inside of an outer structure of the fluid separation section for separating the light phase fluid and transferring it through an open end. Additionally, the swirl acceleration section and the fluid separation section can be annexed to a multi-stage axial flow cyclone separator according to the present invention to increase the velocity of the swirl and to increase the residence time to improve separation efficiency as desired.
