ABSTRACT:
Device for separating a mixture consisting of at least a continuous phase (I) and of at least a conducting disperse phase (II) in the form of particles such as drops in the continuous phase, the two phases having different densities. The device includes at least two substantially cylindrical parts (1, 3) fitted into each other which delimit an annular zone (5), introducing means (6, 7) for introducing the mixture to be separated at the periphery of the outer tubular part (1), arranged so as to communicate a rotational motion to the mixture, means for applying between the two parts (1, 3) a potential difference capable of causing the particles of the disperse phase (II) to coalesce, receiving and decanting means (4), means (8, 9) for discharging the two phases (I) and (II) at least partly separated on account of the differentiated motion of the particles which have coalesced and means for establishing a circulation of the mixture.
