DEVICE FOR DRYING OF DISPERSED MATERIALS IN BOILING LAYER OF INERTIAL BODIES Russian patent published in 2008 - IPC F26B3/12 

FIELD: heating.

SUBSTANCE: in device for drying of solutions in boiling layer of inertial bodies, which contains the chamber with gas distributing grid, on which the layer of inertial bodies is installed, gas supplying box for supply of the main part of fresh coolant, and nozzles that are installed in the layer of inertial bodies with the possibility of their rotation around the chamber axis, nozzles are installed on the vertical hollow driving shaft by means of angle bracket and tubes with nozzles at the ends, which are installed in the horizontal and vertical planes, at that they may be installed with different pitch both in vertical and horizontal directions, depending on object of drying, and in the upper part of chamber, for instance, in the place of transition of cylindrical part into conical part there is a gas distributing grid, in the center of which there is a bearing assembly that serves as the bottom support of hollow driving shaft, at that to conical part of chamber there is at least one nozzle of the secondary coolant tangentially fixed with temperature that is higher than the temperature of the main part of fresh coolant. At that the different shape of inertial bodies is specified.

EFFECT: increase of plant efficiency and reduction of dried material sticking to inertial bodies.
