Procedure and device for fast separation of solid particles and gaseous fluids and their use

摘要

A receptacle (14) open in its upper part into which opens a conduit (13), is inserted between a device (11) for fast extraction and the stripping zone (18). The receptacle (14) consists at its base of at least one diffuser (15) fed in fluidization gas and to which the solid particles are put in a dense fluidized bed state (17), whose density ranges between 300 and 800 kg.m-3, then escape by overflow from the receptacle (14) toward the stripping zone (18) located below.
