VORTEX EVAPORATING AND DRYING CHAMBER WITH INERT PACKING Russian patent published in 2018 - IPC F26B17/10 F26B3/12 F26B3/88 B05B17/04 

FIELD: technological processes.

SUBSTANCE: invention relates to the technique of drying solutions, melts and suspensions and the preparation of granules of various substances and can be used in microbiological, food, chemical and other industries. Vortex evaporating and drying chamber with an inert packing contains evaporating and drying chambers in a common housing with gas-supply and discharge pipelines, as well as a filter heat exchanger, made in the form of a nozzle from a fluidized bed of an inert nozzle, above which there is an irrigator with nozzles. Each of the nozzles contains a hollow body consisting of a cylindrical part, a conical transitional part and a cylindrical part with a large size of diametrical section. Coaxially to the body in its lower part a nozzle is attached, it is formed by a cylindrical surface, which passes into a conical surface. Said nozzle is closed with an end solid partition with a jet in its center. Said body and nozzle form three coaxially interconnected internal cylindrical chambers. In the outlet section of the nozzle diffuser, a perforated partition is installed, to which two spokes are attached, the second end of which is fixed on the inner surface of the diffuser. On the spokes in their central part, additional nozzles are freely installed, made in the form of helical drums, which are fixed to the spokes with the help of stops. In the outlet section of the nozzle diffuser, a perforated conical shell is installed between the perforated partition and additional nozzles, the top of the conical surface of which is fixed on the perforated partition, at the point of its intersection with the axis of the sprayer, while the nozzle cavity between the perforated conical shell and the surface of the perforated partition is filled with an elastic mesh element, or chips from non-ferrous metal, or plastic chips, which increases the fine dispersion of the phase of the sprayed liquid.

EFFECT: increased drying performance by increasing spray uniformity.
