Abstract:
A device for regulating a flow rate in an air-liquid centrifuge separator, for application to a separator, comprising:a fluid inlet pipe at a first level, through which a fluid to be separated is sucked into the separator; a gas outlet pipe through which, aided by an aspirating device, gas is removed from a fluid to be separated; a liquid outlet pipe, through which a liquid separated from the gas is sent on to a further device for treatment of liquids, said liquid outlet pipe being located at a second level below said first level; wherein the device for regulating a flow rate comprises a by-pass pipe, extending upwardly between the liquid outlet pipe and the fluid inlet pipe, which by-pass pipe removes the liquid from the liquid outlet pipe and transfers the liquid upwardly to the fluid inlet pipe when a pressure of the liquid in the liquid outlet pipe exceeds a predetermined level.
