Abstract:
A cyclone for effecting a separation on a fluid stream containing entrained particles, the cyclone including:a body having a circumferential side wall extending between upper and lower ends and defining an interior space, the side wall comprising an upper wall portion and adjacent lower wall portion tapering inwardly in a direction away from the upper wall portion, the upper wall portion defining an inlet for introducing fluid and entrained particles into the interior space and the lower wall portion defining an underflow outlet extending in the direction of the longitudinal axis of the body for removing some fluid and entrained particles; and a vortex finder projecting substantially axially into the interior space through the upper end of the body and terminating at an internal end positioned below the inlet, the vortex finder defining an overflow outlet which removes the remaining fluid and entrained particles from the cyclone; wherein the vortex finder and the upper wall portion are configured to define a feed zone of decreasing cross sectional area from the inlet to the internal end of the vortex finder.
