1. A separator for separating entrained particles from a fluid flow, the separator comprising:
- (a) a cyclone chamber having a cyclonic flow region, the cyclonic flow region having a center, a longitudinal axis, an outer peripheral portion, an inner portion and a radial width;
(b) a fluid inlet for introducing a cyclonic fluid flow to the cyclonic flow region;
(c) a fluid outlet for removing the fluid flow from the cyclone flow region;
(d) a plurality of vanes positioned in the cyclone chamber and extending inwardly towards the center, the vanes having an inner portion and an outer portion and creating a dead space; and
, (e) a cover member spaced from the bottom and positioned above the vanes.

Abstract
An anti-reentrainment device is provided for use with a cyclone separator. The anti-reentrainment device has a plurality of vane upwardly extending members positioned in the bottom of a cyclone chamber and extending radially inwardly across the bottom. The vanes separate the bottom of the cyclone from the cyclonic fluid flow portion, thereby creating a reduced flow region above deposited particles settling on the bottom of the cyclone. The device impedes the cyclonic flow from reentraining the deposited particles.

16. A separator for separating entrained particles from a fluid flow, the separator comprising:
-
(a) a cyclone chamber having a cyclonic flow region, the cyclonic flow region having a center, a longitudinal axis, an outer peripheral portion, an inner portion and a radial width;
(b) means for introducing a fluid flow to the cyclone flow region for cyclonic rotation therein;
(c) separations means for creating a plurality of non-rotational flow regions positioned beneath the cyclonic flow region;
(d) particle receiving means disposed beneath the separations means for receiving particles separated from the fluid flow; and
,(e) means for removing the fluid flow from the cyclone flow region positioned above the particle receiving means. - View Dependent Claims (17, 18, 19, 20)
