Abstract
An anti-reentrainment device is provided for use with a cyclone separator. The anti-reentrainment device comprises a plurality of upwardly extending members positioned towards the bottom of a cyclone chamber and extending radially inwardly across the cyclone chamber. The vanes separate the lower end of the cyclone from the cyclonic fluid flow portion, thereby creating a reduced flow region above particle settling out of a fluid in the cyclone. The device impedes the cyclonic flow from reentraining the separated particles.
Claims20
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.
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.
