CHAMBER FOR HEAT-AND-MASS EXCHANGE BETWEEN DISPERSED PARTICLES AND GAS Russian patent published in 2014 - IPC F26B17/10 F26B3/12 B05B1/34 

FIELD: heating.

SUBSTANCE: chamber comprises body with cover and vessel with porous walls arranged inside said body and aligned therewith. Said vessel houses nozzles and used heat carrier bleeder with porous working surface and drive. Gates are secured inside said vessel while inert carrier ply is filled in there between to up the heat-and-mass exchange efficiency. Note here that at least two rods are secured to rotary hollow porous cylinder, their axes being parallel with cylinder axis. Extra rods are secured to every rod at 45-90 degrees to up the heat-and-mass exchange between heat carrier and dispersed material Nozzle case has fluid feed channel and sleeve rigidly secured and aligned therewith and provided with atomiser attached at its bottom. Said atomiser is composed by cylindrical two-step sleeve, its cylindrical part being screwed to central core and hollow cone aligned therewith. Said cone is fitted with annular clearance relative to cylindrical sleeve cylindrical surface. Said annular clearance communicates with at least three radial grooves made in said two-step sleeve for communication with annular chamber. The latter is composed by sleeve inner surface and upper cylindrical step outer surface. Note here that annular chamber communicates with case fluid feed channel. Sprayer is rigidly screwed to cone bottom part. Said sprayer is composed by round end plate with bends bent off towards aforesaid annular clearance between nozzle and hollow cone. At least two rows of cylindrical orifices, their axes located in planes perpendicular to cone axis. At least three holes are made in every row. Axes of said orifices of one row are shifted to those of orifices in the other row through 15-60 degrees. Inner surfaces of said cylindrical orifices are furnished with helical grooves.

EFFECT: higher efficiency.
