Direct swing separators for the separation of particles in gaseous mixtures and use of the separators for fluidized bed thermal or catalytic cracking

摘要

The present invention relates to a separator for separating particles from a gaseous mixture containing particles, the reactor (R) being directed towards a turning zone (3) adapted to pivot the mixture in a vertical plane at an angle of up to 360 °. A transition region (1) adapted to form a rectangular or square cross section for circulating the mixture in the cavity; An outer wall 30 provided to pivot the mixture at an angle in the range of 70 to 225 °; A deflector (10) pivoting coaxially with respect to the outer wall by at least 30 degrees and by a maximum of 90 degrees to the turning angle of the outer wall; A gas outlet 4 on the same axis as the pivot region; The separator is connected directly or indirectly to the second cyclone 12. The separator also comprises a special outlet 9 with a wall 32 connected to the transition zone 1 and is used for the fluidized bed catalytic cracking of hydrocarbon feedstocks.
