  • Apparatus and method for separating particles from a cyclonic fluid flow
    Patent number: 6533834
    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.

  • Apparatus and method for separating particles from a cyclonic fluid flow
    Publication number: 20010010189
    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.

  • Apparatus and method for separating particles from a cyclonic fluid flow
    Patent number: 6251296
    Abstract: A particle separation member is provided for use with a cyclone separator. The particle separation member divides the separator into a cyclone chamber and a particle receiving chamber. The cyclone chamber and the particle receiving chamber communicate via a plurality of apertures in the particle separation member. The separation member comprises two cooperating members movable between an open position and a closed position to provide access to the particle receiving chamber to empty the collected contents therefrom.
