FIELD: technological processes.
SUBSTANCE: invention relates to solutions drying method to produce a granular product having increased hygroscopicity. In the chamber for conducting heat and mass transfer between the dispersed particles and the gaseous medium containing the body, a container with porous walls located inside the body concentric to it, in which the nozzles and the device for collecting the spent coolant with a porous working surface are located, grids are fixed inside the vessel between which a layer of inert carrier is poured. Nozzle contains a hollow cylindrical body, in the upper part of which an external thread is made for connection to the connection of the distribution pipeline for the supply of liquid. In the lower part of the case an outer thread is made for connection to vortex flow splitter. Case has an inner cylindrical chamber for liquid supply, and in the cylindrical chamber, a hollow conical swirler is coaxially installed with a gap with respect to the inner lateral surface of the chamber, made in the form of a conical surface with a screw through thread, the vertex of the conical surface of the hollow conical swirl is fixed to the end surface of the rod. Vortex flow dissector is fixed to the body by means of a casing having an internal thread and made in the form of a ring to which two diametrically located vertical plates are attached, connected in the lower part by a horizontally arranged rod, in the middle of which there is a second swirler made in the form of a disk with helical blades, embracing the rod in its middle part with a clearance and having stops at the edges in the form of disks arranged perpendicular to the rod.
EFFECT: method for drying solutions is provided to produce a granular product having increased hygroscopicity.
