Separating device and method with a return flow of heavy fraction

摘要

The invention relates to a device for separating a heavy fraction from a fluid, comprising: a main channel; swirl means in the main channel; collecting means adjoining the main channel for collecting the discharge heavy fraction; a concentric additional supply conduit with an outlet and extending into the cylindrical housing; a return channel connecting the collecting means with the additional supply conduit, and deflection means wherein the outlet is encircling the circumference of the additional supply conduit. The invention also relates to a method for separating a heavy fraction from a fluid using such a device.

主权项

1. A device for separating a heavy fraction from a fluid, comprising:
a substantially cylindrical housing defining a main channel; swirl means, positioned in the main channel, for transferring a rotating movement component to the fluid moving through the main channel, thereby separating a heavy fraction; collecting means for collecting the separated heavy fraction, which radially surround openings in the cylindrical housing that are provided to let the heavy separated fraction leave the main channel; an additional supply conduit concentric to the main channel, provided with an outlet, which additional supply conduit at least partly extends into the cylindrical housing; and wherein the additional supply conduit is adapted to receive separated heavy fraction from the collecting means; the additional supply conduit is provided with deflection means, which are positioned downstream of the outlet, the deflecting means causing a fluid exiting the outlet to move in a radial direction,wherein
the outlet of the additional supply conduit is encircling the circumference of the additional supply conduit.
