CHAMBER FOR HEAT AND MASS EXCHANGE BETWEEN DISPERSED PARTICLES AND GASEOUS MEDIUM Russian patent published in 2013 - IPC F26B9/06 F26B3/12 B05B1/14 

FIELD: heating.

SUBSTANCE: in a chamber for heat and mass exchange between dispersed particles and a gaseous medium, comprising a body with a cover, a vessel with porous walls installed inside the body concentrically to it, nozzles installed inside the vessel and a device for bleeding of the spent coolant with the porous working surface, equipped with a drive, and inside the vessel there are lattices fixed, between which there is a layer of an inert carrier filled, which increases efficiency of heat and mass exchange. To increase efficiency of operation of the inert carrier, at least two rods are connected to the rotary hollow porous cylinder, and their axes are parallel to the axis of the cylinder, and are at identical distance from its axis, and to each of rods at the angle of 45…90° there are additional rods attached, making it possible to intensify heat and mass exchange between coolant and dispersed material, according to the invention, the body of the nozzle is made with a channel for liquid supply and comprises a coaxial rigidly connected bushing, with a nozzle fixed in its lower part made in the form of a cylindrical double-staged bushing, the upper cylindrical stage of which is connected by means of a threaded joint with a central core, made of a cylindrical part and a coaxial conical socket installed with a circular gap relative to the inner surface of the cylindrical bushing, and the circular gap is connected at least with three radial channels made in the double-staged bushing, connecting it with the circular cavity, formed by the inner surface of the bushing and the outer surface of the upper cylindrical stage, besides, the circular cavity is connected with the channel of the body for liquid supply, at the same time to the conical socket, in its lower part, there is a receptacle rigidly fixed in the form of an end round plate with at least seven radial tabs, which are bent towards the circular gap between the nozzle and the socket, on the side surface of the socket there are at least two rows of cylindrical throttling holes, with axes lying in planes perpendicular to the socket axis, and in each row there are at least three holes, besides, in the end round plate there are at least three conical throttling holes with an angle near the top of the cone lying in the range of 45° - 90°.

EFFECT: higher efficiency of drying and tempering processes.
