CHAMBER FOR CONDUCTION OF HEAT-MASS EXCHANGE BETWEEN DISPERSED PARTICLES AND GASEOUS MEDIUM Russian patent published in 2008 - IPC F26B3/12 

FIELD: heating.

SUBSTANCE: chamber for conduction of heat-mass exchange contains casing with cover, vessel with porous walls that is installed concentrically inside the casing, nozzle installed inside the casing and device for bleeding of spent gaseous medium with porous working surface, which is equipped with drive. At that inside casing there are grids fixed, between which there is a layer of inertial carrier that increases efficiency of heat-mass exchange. In order to increase efficiency of inertial carrier operation, there are at least two rods fixed to the rotating hollow porous cylinder, the axes of which are parallel to the axis of cylinder and are installed at the same distance from its axis, and additional rods are installed to every of the rods at the angle of 45...90°, which allow to intensify heat-mass exchange between gaseous medium and dispersed particles. The nozzle is made acoustic, and its resonator is made in the form of toroidal cavity or at least one spherical cavity, which is installed in the end wall of the casing that faces distributing head. At that spherical cavity is connected by calibrated opening with clearance between vertical opening in end wall of casing and rod of distributing head, at that in cross-section that is perpendicular to rod axis, the clearance has annular section, and distributing head is made in the form of casing with cover in the form of truncated cones that are connected with their large bases, at that there is a header installed in the casing with the shape of cylindrical cavity, which is connected with annular channel that is formed by external cylindrical surface of hollow rod and identical diameter openings that are coaxial to it and made accordingly in cover and casing of distributing head, with at least three channels for outlet of dispersed particles of solution that are evenly distributed along the circumference and perpendicular to rod axis, at that openings cut is located on the conical surface of distributing head cover, the incline angle of which determines the root angle of sprayed solution torch.

EFFECT: increase of drying and tempering processes efficiency.
