Title:
SYSTEMS AND METHODS FOR REMOVING SOLIDS FROM A FLUID ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO2001081001
Kind Code:
A3
Abstract:
A System and method for removing solids from a fluid environment. The system includes a device (10) for separating solids from a fluid using cyclonic flow. The device includes a column (11) forcollecting solids to be separated from the fluid environment. Th e device (10) also includes a plenum (15) positioned circumferentially about a lower end (14) of the column (11) and an inlet (18) in tangential communication with the plenum (15) for generating a cyclonic flow pattern into the column (11). As the cyclonic flow is introduced into the column (11), the annulus (19) directs the solids in suspension upwards and towards the center of the column (11). The velocity of the flow upward is sufficiently less than the settling velocity of the solids thereby allowing the solids to fall out of suspension. The ascending fluid substantially free of solids can be collected through an upper end of the column (11). The device (10) further includes a draining assembly (30) for collecting the settled solids and for removing the solids therethrough.
