Title (EN) METHOD OF DESALINATING WATER
(FR) PROCEDE DE DESSALEMENT DE L"EAU
Abstract: front page image
(EN)A method of desalinating water consisting in evaporation of water from an aqueous solution of salts while contacting it with air and subsequent condensation of the steam from the air. The evaporation of the water from the aqueous solution of salts while contacting it with the air is carried out with the use of the air as a primary and a secondary flows. The said primary air flow is fed into a cooling zone whereas the secondary flow, together with the aqueous solution of salts, - to an evaporation zone, where the secondary flow is moistured with the water evaporating from the aqueous solution of salts owing to the psychrometric difference of temperatures, so that the moisture content of the said secondary flow is increased, as compared with its initial moisture content, up to 3.5 to 116g/Kg, the moisturing of the secondary air flow thus leading to the cooling of the primary air flow which passes through the cooling zone. The said secondary air flow is formed by drawing off 20 to 90% by volume of the primary air flow after its passage through the cooling zone. The condensation of steam from the air is effected by feeding to a condensation zone the secondary air flow, which has passed the evaporation zone and contains the water vapours, together with the remaining 80 to 10% by volume of the primary air flow, which has passed the cooling zone.
(FR)Un procede de dessalement de l"eau consiste a evaporer l"eau d"une solution aqueuse de sel tout en la maintenant au contact de l"air, puis a condenser la vapeur d"eau de l"air. L"evaporation de l"eau de la solution aqueuse de sel, tout en maintenant celle-ci en contact avec l"air, s"effectue en utilisant l"air sous forme d"un flux primaire et d"un flux secondaire. Le flux d"air primaire alimente une zone de refroidissement tandis que le flux d"air secondaire, avec la solution aqueuse de sel, est envoye dans une zone d"evaporation, ou le flux secondaire est humidifie avec l"eau s"evaporant de la solution aqueuse de sel grace a la difference psychrometrique des temperatures, de maniere a augmenter la teneur en humidite de ce flux secondaire, par rapport a sa teneur initiale en humidite, jusqu"a 3,5-116g/kg, l"humidification du flux d"air secondaire donnant lieu au refroidissement du flux d"air primaire qui passe au travers de la zone de refroidissement. Ce flux d"air secondaire est forme en purgeant 20 a 90% en volume du flux d"air primaire apres son passage au travers de la zone de refroidissement. La condensation de la vapeur d"eau de l"air s"effectue en envoyant vers une zone de condensation le flux d"air secondaire, qui passe par la zone d"evaporation et contient la vapeur d"eau, avec les 80 a 10% en volume restant du flux d"air primaire qui passe par la zone de refroidissement.
