EMISSION INSTALLATION FOR CONCENTRATION OF LIQUID SOLUTIONS Russian patent published in 2017 - IPC G21F9/00 

FIELD: machine engineering.

SUBSTANCE: evaporator for concentrating the liquid solutions contains at least one evaporation stage including a rotary drum, a supply tube of the initial solution into its internal cavity, an evaporated solution discharge tube and a device for cleaning its inner surface. The plant is equipped with a steam compressor, the output of which is connected by a pipeline to the heating steam jacket of the drum of the first stage of evaporation, and the compressor inlet is connected by a pipeline to the inner cavity of a single-stage reel or to the inner cavity of the reel of the last stage of evaporation. The heating jacket of each stage is connected by a pipeline to the inner cavity of the reel of the previous stage. The number of stages is selected from the condition of exceeding the additional generation of steam during the transition of the steam compressed from the superheated state into the saturated state over the total difference of the condensed and generated steam flows in the reels of all evaporation stages.

EFFECT: invention allows to reduce energy costs while ensuring continuous operation.
