Patent ID: 8353411

Claim:
A separating cyclone for separating a mixture of liquids and/or gases into a heavy fraction with one or more liquids and/or gases of a relatively high specific mass and a light fraction with one or more liquids and/or gases of a relatively low specific mass, the cyclone comprising: a cyclone tube in which a flow space is defined, wherein the cyclone tube is provided with an inlet for infeed of the mixture, a heavy fraction outlet for discharging the heavy fraction separated from the mixture and a light fraction outlet for discharging the light fraction separated from the mixture; a rotation generating unit for setting the mixture into rotation; a flow body arranged substantially concentrically in the cyclone tube and comprising a light fraction discharge channel connected to the light fraction outlet, the discharge channel comprising a channel portion having a cross-section which decreases in the flow direction; a first pressure control element connected to the heavy fraction outlet for adjusting the flow rate of the heavy fraction; a second pressure control element connected to the light fraction outlet for adjusting the flow rate of the light fraction; and control means configured to control the first and second pressure control elements to cause the interface between the heavy fraction and light fraction to make contact with an inner surface of the discharge channel during use.
