Title: Device intended for separating fluids and solids from a carrier fluid
Inventor: YVES LECOFFRE
IPC: B04B1/00
Filed: 1989-10-11
Abstract: The present invention relates to a device making it possible to separate the various phases of a mixture comprising at least two phases. The phases in question are liquid, solid or gaseous, at least one of them being fluid. The mixture to be separated is injected into the annular space made between two coaxial cylinders 2 and 3 and parallel to their axes, the cylinders rotating at rotation speeds which are virtually inversely proportional to their diameters. The various phases are separated in this space by a centrifuge effect and can be extracted therefrom via three channels, through the outer cylinder 2, through the gap 6 made between the two cylinders at one ends of the annular space or through the inner cylinder 3. In some cases, the cylinders may be fitted with devices which allow an additional separation. The device is furthermore fitted with impellers (rotors) 9, 10, 11, 12 through which the separated phases pass. By correctly designing (dimensioning) these wheels, the head loss (pressure drop) of the system is reduced or made zero. The rotating parts are essentially placed in a pressure-resistant container.
