摘要：The device for separating particles in at least one separation chamber from agaseous mixture has an inlet for the mixture connected to an elongated reactor (R) whichsupplies the mixture and a first outlet (4) producing a gaseous effluent from theseparation which contains a small quantity of particles and a second outlet (9) producingthe majority of the particles. The separation chamber combines a transition zone (1)connected to the inlet with a rectangular or square section passage carrying the mixtureto a coiled zone (3). The coiled zone is designed to rotate the mixture in the verticalplane through an angle of less than 360 degrees and comprises two vertical walls (6)between which the rotation occurs, and an external wall (30) describing the coil turningthe mixture through between 70 and 225 degrees , and an internal deflector wall (10)connected tangentially to the transition zone and coiling coaxially with the external wallthrough an angle of at least 30 degrees and at most 90 degrees . The first outlet is oneor two tubes, each accessed by a hole pierced in one (each) of the vertical walls of the
coiled zone. The outlet is coaxial with the coiled zone so the connection of the outlet andthe deflector is tangential. The second outlet has a first wall (31) connected to theexternal wall of the coiled zone and a second wall (32) connected to the transition zoneor the reactor. Also claimed is the use of the above separator where the reactor is acatalytic cracker of hydrocarbons.
