Separator for separating a mixture of two liquids

Claim 1

A separator for separating a mixture of two immiscible liquids of different densities, one of these being dispersed in the other, said separator including, superposed in a cylindrical tank, an injection chamber for injecting the mixture and disposed between a coalescence chamber and a collecting chamber for collecting the dispersed component, a tubular collector for collecting the continuous phase, said coalescence chamber being arranged concentrically around said tubular collector, a deflector separating said coalescence chamber and said injection chamber and forming an annular passage for communicating said injection chamber with the coalescence chamber, said annular passage being formed between the wall of the tank and the periphery of said deflector, funnels surmounting said deflector for communicating the coalescence chamber with the collecting chamber, said injection chamber being provided with a static central injector having vanes for imparting a centrifugal rotating motion to the mixture, a first pipe penetrating the collector and extending axially therethrough for feeding the mixture of the two liquids and opening to the vanes of said static central injector, a second pipe situated at the top of the tank for evacuation of the dispersed phase and a third pipe opening to the base of the collector for evacuation of the continuous phase.
