摘要：Device for separating a mixture consisting of at least a continuous phase (I) andof at least a conducting disperse phase (II) in the form of particles such as drops in thecontinuous phase, the two phases having different densities. The device includes at leasttwo substantially cylindrical parts (1, 3) fitted into each other which delimit an annularzone (5), introducing means (6, 7) for introducing the mixture to be separated at theperiphery of the outer tubular part (1), arranged so as to communicate a rotationalmotion to the mixture, means for applying between the two parts (1, 3) a potentialdifference capable of causing the particles of the disperse phase (II) to coalesce, receivingand decanting means (4), means (8, 9) for discharging the two phases (I) and (II) at leastpartly separated on account of the differentiated motion of the particles which havecoalesced and means for establishing a circulation of the mixture.
