PLANT OF SOLUTIONS DRYING IN BOILING BED OF INERT BODIES Russian patent published in 2008 - IPC F26B3/12 

FIELD: heating.

SUBSTANCE: plant for solutions drying in boiling bed of inert bodies consists of drying chamber with injectors, two gas-distributing lattices. One of gas-distributing lattices contains central cone-shaped distributor and nozzle of inert bodies is located between gas-distributing lattices. Besides, the other gas distributing lattice contains cone-shaped distributor and vertical drive rod installed so that to enable its vertical and rotary movement by means of worm-gearing. Central cone-shaped distributors of lattices are directed towards each other with their tops. Each of injectors is acoustic and contains resonator in the shape of, at least, one spherical hollow situated in the end wall of body and directed to distributing head. Besides, spherical hollow is connected with gap between vertical opening in end wall and distributing head rod by means of calibrated opening. In addition, gap is of annular cross section in the section perpendicular to rod axis. Distributing head is in the shape of housing with cover represented with truncated cones interconnected by large basis. Besides, manifold in the form of cylindrical hollow is located inside the housing. Manifold is connected with annular channel formed by external cylindrical surface of hollow rod and coaxial openings of similar diameter provided in distributing head cover and housing. Distributing head is provided with, at least, three channels for solution discharge, which are evenly distributed around and perpendicular to rod axis. In addition, opening shearing is on the tapered surface of distributing head cover and inclination angle defines rooted angle of sprayed solution jet.

EFFECT: improvement of drying efficiency.
