Three-phase cyclone separator

Three-phase cyclone separator for separating a mixture or an emulsion into a low density phase, a high density phase and an intermediate density phase, comprising a body formed by a cylindrical part extended at one of its ends by a converging, substantially conical part, at least one intake mounted tangentially on the cylindrical part and a substantially tubular element mounted on the body and communicating hydraulically therewith, wherein the substantially tubular element is mounted on an annular element closing the end of the cylindrical part opposite the substantially conical part, the substantially tubular element projecting into the body beyond the annular element, and the substantially conical part is fitted, towards its apex, with a first outlet for said low density phase and a second outlet for said high density phase and the substantially tubular element defines, at its end opposite to said body, a third outlet for said intermediate density phase and wherein the substantially tubular element, the body and the three outlets are arranged coaxially.
