Abstract

A cyclone separator especially useful for separating gases from solid materials which tend to cohere and foul conventional cyclones is described. The cyclone is provided with baffle means within the cyclone barrel below the natural vortex to reduce the residual spin of the gas-solid suspension below the natural vortex thereby lessening the tendency toward fouling.

Claims

1. A cyclone separator including an elongated barrel, a transition piece and a dipleg, an inlet for introducing solidladen gases tangentially into the barrel, an outlet for removing separated gases from the barrel, an outlet for removing separated solids from the transition piece and dipleg, and baffle means for reducing the residual centrifugal forces of the separated solids, said baffle means being located below the outlet for removing separated gases at a distance which is equal to or greater than half the length of said barrel, and said baffle means comprising a cone part and a plurality of fins having upper and lower fin sections mounted axially on a shaft, said shaft being centrally positioned within the cyclone so that the cone part and upper fin sections extend downwardly toward the transition piece and outwardly toward the barrel walls, and the lower fin sections extend downwardly and inwardly into the transition piece.

2. The cyclone separator of claim 1 wherein the baffle contains from two to 10 fins.

3. The cyclone separator of claim 1 wherein the cone part together with the upper fin sections is about equal to half the length of said barrel, and the length of lower fin section is about one quarter the length of said barrel.

4. The cyclone separator of claim 3 wherein the maximum radial dimension of the upper and the lower fin sections of the baffle is from about half to about equal to the radius of the barrel and the minimum radial dimension is about half the maximum radial dimension.

5. The cyclone separator of claim 1 wherein the shaft is provided with support pins and stabilizing fins to center and support the shaft within the cyclone separator.
