Abstract
A separating cyclone for at least partially separating a mixture of fluids of different density into a light fraction with a relatively low density and a heavy fraction with a relatively high density, comprising a flow body in a flow space between the flow body and casing around the flow body wherein at least one bypass channel is provided in the distal part of the flow body, via which channels a part of the mixture flowing along the flow body in the flow space can be guided. Also, a method for separating the above stated mixtures.

Separating cyclone for at least partially separating a mixture of fluids of different density into a light fraction with a relatively low density and a heavy fraction with a relatively high density, comprising:
- an outer casing which defines a flow space through which the mixture is to flow;
- an inlet connected distally to the outer casing for admitting the mixture for separating into the flow space,
- a flow body disposed in the flow space wherein the mixture can be guided in a flow direction through the flow space and between the flow body and the outer casing and wherein the flow body has a distal part of decreasing diameter in the flow direction;
- a rotator device in the flow space for setting into rotation the mixture for separating;
- a first outlet connected proximally to the outer casing for discharging the heavy fraction from the flow space;
- a second outlet disposed in the flow space for discharging the light fraction from the flow space, and
- at least one bypass channel at the distal part of the flow body, each bypass channel being shaped and positioned for guiding a part of the mixture flowing along the flow body in the flow direction.
Flow body for placement into a separating cyclone for at least partially separating a mixture of fluids of different density into a light fraction with a relatively low density and a heavy fraction with a relatively high density, wherein the flow body comprises a proximal part on which a rotating device is arranged for setting into rotation the mixture flowing along the body, and also comprises a distal part of decreasing diameter in a flow direction of the mixture, at least one bypass channel at the distal part via which a part of the fluid flowing along the flow body can be guided.
Method for at least partially separating a mixture of fluids of different density into a light fraction with a relatively low density and a heavy fraction with a relatively high density, comprising:
- feeding the mixture for separating into a flow space defined by and between an outer casing and a flow body disposed in the casing;
- setting the mixture into rotation in the flow space;
- guiding the mixture, once set into rotation, along the flow body disposed in the flow space;
- discharging the heavy fraction via a first outlet connected proximally to the outer casing;
- discharging the light fraction from the flow space via a second outlet disposed in the flow space, and
- guiding a part of the mixture flowing along the flow body through at least one bypass channel arranged in the flow body at a distal part of the flow body.
