| 摘要 |
The invention relates to a device for evacuating a fluid (5) which is supplied to a reaction chamber (1) containing solid particles fluidified by said fluid, through a rotary chamber (100) provided with a blade (14) wheel (13) that can discharge the solid particles concentrated along the rotary circular wall (8) of the rotary chamber into the reaction chamber, under the effect of the centrifugal force. The invention also relates to methods of catalytic polymerisation, combustion, gasification, drying, impregnation, coating or other treatments of solid particules in suspension in a fluid, or cracking, dehydrogenation or other catalytic transformations of fluids, using said device.
