CATALYSTS DRYING AND CALCINATION PLANT Russian patent published in 2018 - IPC F26B9/06 F26B3/12 F26B20/00 B05B17/04 

FIELD: technological processes.

SUBSTANCE: invention relates to a method for drying solutions to produce a granular product with increased hygroscopicity, and can be used in various areas of chemical technologies and related industries where higher requirements on the final moisture content of the product are imposed. Catalyst drying and calcination plant comprises a spray dryer with a sprayer comprising a body, a nozzle with a blind partition and a nozzle at its center, the body and nozzle form three coaxial inner cylindrical chambers. In an outlet section of the diffuser of the sprayer attached to an end surface of a cylindrical part of the body, a perforated partition is installed to which at least two spokes are fixed to one end at the point of its intersection with the axis of the sprayer, second end of which is fixed to an inner surface of the diffuser in such a way that the spokes are perpendicular to the inner surface of the diffuser, and on the spokes, in their central part, additional sprayers are freely installed, made in the form of screw drums, which are fixed on the spokes with the help of stops.

EFFECT: increasing the efficiency of drying and calcination processes.
