TURBULENT EVAPORATOR AND DRYING CHAMBER WITH PASSIVE NOZZLE Russian patent published in 2008 - IPC F26B3/12 

FIELD: heating.

SUBSTANCE: turbulent evaporative and drying chamber with passive nozzle includes evaporator and dryer chambers combined in one housing with gas supply and discharge pipelines, filtering heat exchanger represented as nozzle of inert bodies boiling bed. Sprinkler located above this nozzle is represented with bearing rotated manifold with controlled throttle of primary solution supply. Exhaust dusty gases are subject to preliminary acoustic treatment in acoustic plant. Dusty gases are then supplied to cyclone with silo where the main part of gas-entrained dry material is released. Finally, gas cleaned in sleeve filter with silo. Besides, injectors are represented as acoustic injectors while resonator is in the shape of, at least, one spherical hollow located in the end wall of housing directed to distributing head. In addition, spherical hollow is connected with calibrated opening provided with gap between vertical opening in end wall of housing and distributing head rod. Gap is of circular cross section in section perpendicular to rod axis. Distributing head is represented with housing with cover in the form of 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.
