Device and process for gas-solid separation of catalytic cracking in fluidized bed with deflector under window

摘要

Device and a method for separating and stripping a gas mixture and solid particles comprising a plurality of separation (12) and pre-stripping (13) chambers distributed around a central reactor (14), each pre-stripping chamber ( 13) comprising a peripheral wall (25), two substantially vertical side walls (20) which are also the side walls of the separation chambers (12), a lower inlet opening (24) for stripping gas adapted to communicate with a stripping chamber (23), and an upper outlet opening (31) for the gas mixture and stripping gas adapted to communicate with a second separation stage, in which a baffle (28) is disposed between the stripping chamber (23) ) and the pre-stripping chamber (13) and is adapted to deflect the ascending stripping gas and forcing said stripping gas to have at least one substantially horizontal movement.
