FIELD: heating. ^ SUBSTANCE: plant for solution drying with passive nozzle includes housing with gas-distributing lattice and injector for solution spraying. Heated chamber is located in housing in axial alignment to it. Pipe with radial orifices and expanding nozzle linked to gas-distributing nozzle is connected to the lower part of chamber and intended for supply additional coolant. Injector for solution spraying is implemented as acoustic injector containing resonator in the form of toroidal hollow or, at least, one spherical hollow located in end wall of housing, directed to distributing head. Spherical hollow is linked to gap between vertical opening in end wall and distributing head rod by means of calibrated orifice. In addition, gap cross section is circular in point perpendicular to rod cross section. Distributing head is in the shape of housing with cover represented with truncated cones interconnected by their 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. ^ 3 cl, 2 dwg |
