Abstract:
A cyclonic separator for separating fluids of differing densities from a mixture thereof, comprising,a vessel,a first stage cyclone separator housed within said vessel and including a first separation chamber having an inlet for the mixture to be separated, an underflow outlet for a more dense fluid phase separated from said mixture, and an overflow outlet for a less dense fluid phase separated from said mixture,an inlet conduit communicating with said inlet of said first stage cyclone separator for conducting said mixture through the wall of said vessel to said inlet,an outlet conduit communicating with said underflow outlet of said first stage cyclone separator for conducting said more dense fluid phase from said outlet through the wall of said vessel, and,said overflow outlet of said first stage cyclone separator in use discharging said less dense fluid phase into said vessel, and including a vortex finder and means for deflecting the flow which issues from the vortex finder to promote separation therefrom of any entrained more dense fluid phase, whereby said overflow outlet and said vessel define a second stage cyclone separator, separated more dense fluid phase of the overflow mixture from the first stage being collected in said vessel.
