DISTILLATION MODULE FOR CONCENTRATION AND DESALINATION OF AQUEOUS SOLUTION AND METHOD OF CONCENTRATING AND DESALTING AQUEOUS SOLUTION USING THEREOF Russian patent published in 2020 - IPC B01D61/36 

FIELD: technological processes.

SUBSTANCE: invention relates to a distillation module for concentration and desalination of an aqueous solution, comprising a heat carrier chamber, one wall of which is an evaporation surface, a condensation chamber with a coolant, one wall of which is a porous condensation surface of vapours with an air gap between the evaporation surface and the vapour condensation surface, coolant circuit with pump connected to condensation chamber. Module is characterized by that evaporation surface is made in form of solid heated wall with device of sprinkling it from gap side with initial water solution, porous surface of condensation of vapours - in form of porous plate, and pump is located after condensation chamber. Invention also relates to a method of concentrating and desalting an aqueous solution.

EFFECT: technical result is reduced contamination and membrane contamination with simplicity and cost effectiveness of desalination and concentration of aqueous solutions.
