Abstract

La présente invention concerne appareil de récupération d'énergie dans un système de dessalement utilisant l'osmose inverse, comprenant essentiellement : un module (3) d'osmose inverse ; une paire de chambres (5) de récupération d'énergie ; et une vanne (7) de commutation de passages. Ladite vanne (7) de commutation de passages est constituée d'une ou plusieurs entrées (31) dans lesquelles entre un fluide à haute pression, au moins une paire de sorties (33 et 34) servant à évacuer alternativement du fluide à partir de l'intérieur, et au moins une paire de trous (35 et 36) de vidange servant à vidanger alternativement du fluide à partir de l'intérieur, et comprend essentiellement : un corps (30) de tube doté de parties (37-1, 37-2, 37-3 et 37-4) de plaques d'admission ou de vidange dépassant chacune au voisinage les unes des autres sur une périphérie intérieure de celui-ci entre les entrées (31), les sorties (33 et 34) et les trous (35 et 36) de vidange ; une tige (50) d'actionnement dotée d'un moyen (53-1, 53-2, 53-3 et 53-4) d'accrochage d'admission ou de vidange dépassant sur une périphérie extérieure de celle-ci de façon à correspondre aux parties (37-1, 37-2, 37-3 et 37-4) de plaques on a one-to-one basis ; et une pluralité de corps (70-1, 70-2, 70-3 et 70-4) de soupapes d'admission ou de vidange servant à bloquer l'écoulement du fluide à travers les parties (37-1, 37-2, 37-3 et 37-4) de plaques. Par conséquent, l'action d'ouverture et de fermeture des soupapes peut être commandée simultanément à l'aide d'une seule tige d'actionnement et d'un actionneur, ce qui permet de réduire considérablement les coûts d'équipement et d'exploitation et, comme l'eau concentrée à haute pression n'est pas directement vidangée dans un réservoir de vidange pendant le fonctionnement de la vanne, d'accroître considérablement le taux de récupération d'énergie de pression.
