APPARATUS FOR TREATING WATER VIA CRYSTALLISATION METHOD Russian patent published in 2014 - IPC C02F1/22 C01B5/02 B01D59/08 C02F103/04 

FIELD: chemistry.

SUBSTANCE: apparatus has a housing (5), inside of which there is a sealed variable-volume vessel (10), in the top part of which there is a filter (4) for separating heavy water crystals, above which there is an opening (3) for outlet of light water. The filter (4) is attached to the housing (5). Between the filter (4) and the bottom of the vessel (19), having a hose for inlet of water (14) to be treated, there are hollow rings (18), inside of which there are heat exchangers (12), having the shape of Archimedes' spirals connected by flexible hoses in series, and the rings themselves are connected to each other by flexible sleeves (11). The cavity of the lower heat exchanger (12) is linked by a flexible hose (14), which passes through the wall of the housing, with the inlet cavity for the heat carrier (16), having a temperature control device (15) and connected to the volume (17) of the housing (5). The cavity of the top heat exchanger (12) is connected through a valve (6) to the cavity of the outlet pipe for the heat carrier (8), having a temperature control device (7) and linked through a valve (9) to the cavity (17) of the housing (5).

EFFECT: apparatus provides cheap and easy production of deuterium-free tap water.
