Abstract

Μία μέθοδος για την αφαλάτωση υδάτινου διαλύματος ηλεκτρολύτη συνίσταται στην τροφοδοσία υδάτινου διαλύματος σε ανοδικό θάλαμο (5) και την εφαρμογή ηλεκτρικού ρεύματος στην άνοδο (9) και τη κάθοδο (18). Ταυτόχρονα, η ηλεκτρόλυση στον ανοδικό θάλαμο (5) παράγει όξινο διάλυμα, το οποίο διοχετύεται σε θάλαμο αραιώσεως (7) και καθοδικό θάλαμο (8). Τα ιόντα άλατος και το οξύ μεταφέρονται επιλεκτικά μέσω μεμβρανών (2), (3), (4), πράγμα το οποίο επιφέρει την αφαλάτωση του υδάτινου διαλύματος. Το συμπύκνωμα αποβάλλεται από το θάλαμο (6) και το αφαλατωμένο διάλυμα από το θάλαμο (8). Μια συσκευή ηλεκτροδιαπηδήσεως περιλαμβάνει περίβλημα (1) με σωλήνα (13) για την τροφοδότηση υδάτινου διαλύματος που ευρίσκεται στο θάλαμο (5) και ένα σωλήνα (21) εγκατεστημένο στο θάλαμο (8) για την αποβολή του αφαλατωμένου υδάτινου διαλύματος. Το περίβλημα (1) περικλείει τις μεμβράνες (2), (3), (4) οι οποίες διαμορφώνουν ένα ανοδικό θάλαμο (5), τουλάχιστον ένα ζεύγος (22) θαλάμων και τον καθοδικό θάλαμο (8). Το ζεύγος (22) θαλάμων περιλαμβάνει ένα θάλαμο συμπυκνώσεως (6) και το θάλαμο αραιώσεως (7). Προβλέπεται η ύπαρξη διαύλου στους θαλάμους συμπυκνώσεως (6). Μια οποή (17) διανοίγεται στη μεμβράνη (4). ωOne method for desalination of an aqueous electrolyte solution is to supply an aqueous solution to an ascending chamber (5) and apply an electric current to the ascent (9) and descent (18). At the same time, electrolysis in the ascending chamber (5) produces an acidic solution, which is injected into a dilution chamber (7) and a catarrhal chamber (8). Salt and acid ions are selectively transported via membranes (2), (3), (4), which results in the desalination of aqueous solution. The concentrate is excreted from the chamber (6) and the desalinated solution is excreted from the chamber (8). An electric swing device includes a housing (1) with a tube (13) to supply a water solution in the chamber (5) and a tube (21) installed in the chamber (8) to expel the unsalted aqueous solution. Casing (1) encloses the membranes (2), (3), (4) which form an upward chamber (5), at least one pair (22) of chambers and the downward chamber (8). The pair (22) of chambers includes a condensing chamber (6) and the dilution chamber (7). There is a channel in condensing chambers (6). One (17) is opened in the membrane (4). ω
