CHAMBER FOR CONDUCTION OF HEAT-MASS EXCHANGE BETWEEN DISPERSED PARTICLES AND GASEOUS MEDIUM Russian patent published in 2018 - IPC F26B17/10 F26B3/12 B05B1/34 

FIELD: technological processes.

SUBSTANCE: invention relates to a method for drying solutions to produce a granular product with increased hygroscopicity, and can be used in various areas of chemical technologies and related industries where higher requirements on the final moisture content of the product are imposed. In the chamber for conducting heat and mass transfer between the dispersed particles and the gaseous medium containing the body, placed inside a concentric vessel with a porous wall, located inside the nozzle vessel and a device for the collection of spent coolant with a porous working surface, equipped with a drive. Nozzle comprises a hollow cylindrical body with a fitting rigidly connected to the body and coaxially disposed in the upper part of the body and having a cylindrical fluid inlet connected to a diffuser axially symmetric to the body and the fitting, the hollow conical swirler is fixed in the lower part of the cylindrical hole, the conical shell of which is fixed by means of at least three spokes fixed at one end to the conical shell of the swirler in its upper part, and at other end – in the annular groove made on the inner surface of the cylindrical hole, on the outer surface of the hollow conical swirler a screw through thread is made, and a sprayer located perpendicular to the axis of the housing and being made in the form of a solid disk is connected to the housing, at its lower part, by means of at least three spokes, the disk of the atomizer being formed by two surfaces, one of which, facing the diffuser, is a curvilinear surface, and the line forming this surface is a curve of the n-th order, and the second is the plane, or the disk of the atomizer is formed by two congruent and equidistant surfaces of the n-th order, and the spokes, by which the disk of the sprayer is fixed to the body, are straight or curved in shape.

EFFECT: use of the chamber allow to prevent pollution of the atmosphere.
