Title: Apparatus for separating solid particles from mixture of fluid and solid particles
Inventor: HENDORIKUSU EHIDEIUSU ANTONIA
IPC: B04C7/00
Filed: 1989-09-20
Abstract: PURPOSE: To efficiently separate solid particles by disposing a swirl chamber and a cyclone separator having a central longitudinal axis common with the swirl chamber and providing the cyclone separator with a swirl tube. CONSTITUTION: The mixture composed of gas and solid particles is introduced through a tangential inlet 9 and an inlet opening 7 into the swirl chamber 3. The tangential inlet 9 imparts a first swirl to the mixture around the central longitudinal axis 5 of the swirl chamber 3 cooperatively with the curved wall of the swirl chamber 3.
