DEVICE WITH A FLUIDIZED SPOUTED BED OF ANNULAR FORM AND THE METHOD OF ITS WORK Russian patent published in 2018 - IPC B01J8/24 B01J19/24 F26B17/14 F23C10/02 

FIELD: technological processes; chemistry.

SUBSTANCE: invention relates to a reaction chamber of a device with a fluidized spouted bed of annular shape for carrying out various chemical reactions, including purification of gas mixtures, drying materials, pyrolysis, gasification, burning solid fuel material, as well as the way of it works. Reaction chamber of the device has at least a part of the height of the funnel-shaped, narrowing downward form with a stepped structure of the inner surface and a tube coaxial with the reaction chamber for withdrawing the treatment products. To feed the fluidizing gases and / or materials and / or reagents in the device, channels passed through the reaction chamber housing are made.

EFFECT: such form of the reaction chamber, together with the tangential supply of fluidized and other gases into it, allows to create a controlled toroidal fluidized bed in the reaction chamber, in which it is possible to regulate the rotation speed of the parts of the processed material in both the horizontal and vertical planes, and also to control the residence time in the reaction zone of parts of different fineness, the intensity of processing of materials and other parameters of technological processes.
