LAMINAR-FLOW CENTRIFUGAL SEPARATOR

摘要

The rotary bowl (1) of this centrifugal separator is lined with conical structures divided into sectors (7) separated by angularly offset gaps (9) so as to promote a regular spiral fluid flow therein, which is laminar and enhances separation efficiency significantly: in the case of two-phase or three-phase suspensions, a “cake” is obtained on the side wall (8). A scraper (15) rotating at a slightly different speed may be added to enable simultaneously routing of the solid cake to the outlet and continuous processing.

主权项

1. Centrifugal separator comprising a rotary bowl (1) having a peripheral wall (8), a separation structure situated in the bowl and rotating synchronously with the bowl, a mixture inlet conduit (5) situated on a rotational axis (2) of the bowl and opening (6) in the bowl, the bowl comprising at least one outlet orifice (10) for at least one light fraction of the mixture to a first axial side of the bowl, the separation structure comprising a stack of cones divided into angular sectors (7) separated by angular gaps (9), the angular gaps being covered by the sectors (7) of the immediately adjacent cones, and the sectors having peripheral ends at an identical distance from the peripheral wall.
