Abstract:
An apparatus for separating particles, comprising at least one separation chamber for separating said particles from a gaseous mixture, said separation chamber comprising a mixture inlet connected to a vertical elongate reactor R, for delivering said mixture, a first outlet (4) for delivering a gaseous effluent resulting from separation, containing a minor quantity of particles, and a second outlet (9) for delivering a major portion of the particles, the separation chamber comprising, in combination:a transition zone (1) connected to said inlet and adapted to form a rectangular cross section for passage of the mixture circulating from the reactor to a turning zone (3):said turning zone (3) for turning the flow, being connected to the transition zone and adapted to rotate the mixture in a vertical plane through an angle which is less than 360.degree., comprising two substantially vertical walls (6), between which said rotation occurs, and an external wall (30) defining the turn of said mixture through an angle which is in the range 70.degree. to 225.degree.; and an internal deflector wall (10) tangentially connected to the transition zone and turning substantially coaxially with the external wall through an angle of at least 30.degree. and at most the angle through which the external wall turns, plus 90.degree.;the first outlet (4) for delivering the gaseous effluent being constituted by a tube having a horizontal span in communication with an inlet (5) comprising an orifice pierced in one of the vertical walls (6) of the turning zone, or by two tubes of which each inlet is an orifice pierced in each of said walls; said first outlet being substantially coaxial with the turning zone such that the connection of said outlet and said deflector is substantially tangential;the second outlet (9) comprising a first wall (31) connected to the external wall (30) of the turning zone and a second wall (32) connected to transition zone (1) or to the reactor.
