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 communicating via a plurality of apertures in the particle separation member.
Claims40
A separator for separating entrained particles from a fluid flow, the separator comprising:
- a) a cyclone chamber having an outer wall and a cyclonic flow region, the cyclonic flow region having a radial width, an outer peripheral portion, a medial portion disposed interior of the peripheral portion and an inner portion disposed interior of the medial portion, the inner portion having a radial inner extent and the outer portion having a radial outer extent;
- 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 cyclonic chamber;
- a particle separating member positioned in the cyclone chamber beneath at least a portion of the cyclonic flow region, the particle separating member having a continuous surface from the radial inner extent of the inner portion to the radial outer extent of the outer portion except for a plurality of apertures;
- and,
- d) a particle receiving chamber disposed beneath the particle separating member for receiving particles passing into the particle receiving chamber through the apertures, the particle receiving chamber having an essentially sealed bottom wherein the apertures are disposed on the particle separating member such that the medial portion of the cyclonic flow region is substantially free from said apertures and the particle separating member is configured to inhibit re-entrainment of particles from the particle receiving chamber to the cyclonic flow region.

A separator for separating entrained particles from a fluid flow, the separator comprising:
- a) a cyclone chamber for containing a cyclonic flow in a cyclonic flow region, the cyclonic flow region having a radial width, an outer peripheral portion, a medial portion disposed interior of the peripheral portion and an inner portion disposed interior of the medial portion;
- b) means for introducing a fluid flow to the cyclone flow region for cyclonic rotation therein;
- c) means for removing the fluid flow from the cyclone chamber;
- d) particle receiving means disposed beneath the cyclone flow region for receiving particles separated from the fluid flow;
- e) separation means for essentially isolating the particle receiving means from the cyclone chamber except for transporting means associated with the separation means for connecting the particle receiving means in flow communication with the cyclonic flow region such that, in operation, particles pass through the transporting means to the particle receiving means.

A method of separating entrained particles from a fluid flow, the method comprising the steps of:
- a) introducing a fluid to flow cyclonically in a chamber having a cyclonic flow region, the cyclonic flow region having a radial width, an outer peripheral portion, a medial portion disposed interior of the peripheral portion and an inner portion disposed interior of the medial portion;
- b) removing particles from the fluid flow in the cyclone chamber via passages provided beneath one or both of the peripheral and inner portions into an area beneath the passages without any substantial re-entrainment of separated material from the area to the cyclonic flow region and essentially terminating cyclonic flow in the area beneath the passages;
- and,
- c) removing the fluid flow from the chamber.
