Title (EN) AN APPARATUS FOR CLEANING WATER
(FR) EPURATEUR D'EAU
Abstract:
(EN) The invention relates to an apparatus for electrical purification of water, said apparatus comprising a reaction chamber (1) provided with side walls (2), a bottom wall (3), a top wall (4) and a partition wall (5) dividing the reaction chamber into a first chamber (6) and a second chamber (7), each provided with a mainly vertical electrode (8), the partition wall and the electrodes being disposed at a distance from the bottom wall; an inlet (9) for the water to be purified; an outlet (10) for the purified water; a power source (11) and a gas outlet. According to the invention, the inlet for the water to be purified is located in a wall (2, 3, 4) of the first chamber (6) and the outlet (10) for the purified water in a wall (2, 3, 4) of the second chamber (7), so that the water to be purified can circulate freely from the first chamber (6) into the second chamber (7), washing the electrodes (8) and the reaction chamber (1).
(FR) La présente invention concerne un appareil d'épuration électrique de l'eau, cet appareil comportant une chambre de réaction (1) pourvue de parois latérales (2), d'un fond (3), d'un dessus (4) et d'une cloison séparatrice (5) qui divise la chambre de réaction en un compartiment (6) et un deuxième compartiment (7), chacun d'eux étant équipé d'une électrode sensiblement verticale (8). La cloison séparatrice et les électrodes sont placées à une certaine distance du fond. Il y a une entrée (9) pour l'eau à épurer, une sortie (10) pour l'eau épurée, une source d'électricité (11) et un orifice d'évacuation des gaz. Selon l'invention, l'entrée de l'eau à épurer se trouve dans une paroi (2, 3, 4) du premier compartiment (6) et la sortie (10) de l'eau épurée se trouve dans une paroi (2, 3, 4) du deuxième compartiment (7), de telle sorte que l'eau à épurer peut circuler librement du premier (6) au deuxième (7) compartiment, rinçant ainsi les électrodes (8) et la chambre de réaction (1).
