Title
(EN) CONTACT AND DEGASSING TANK FOR EQUIPMENT FOR OZONATION TREATMENT
(FR) RÉSERVOIR DE CONTACT ET DE DÉGAZAGE POUR ÉQUIPEMENT DE TRAITEMENT PAR OZONATION
Abstract
(EN)
Device (100) for the treatment and temporary storage of liquids, the device (100) comprising a tank (10), working under pressure, adapted to contain and treat fluid for the purification of ship ballast water; an inlet aperture (20) for supply of ozone, hydrogen peroxide and treatment water within the tank (10); a take-out aperture (30) for taking the fluid for purification of ballast water out from the tank (10); a tubular element (40), placed inside the tank (10) and set in fluid communication with the inlet aperture (20), the tubular element (40) being adapted to release the fluid for purification of ballast water near the bottom (101) of the tank (10). The device is characterised in that it includes at least one helical element (50, 50', 50") coaxial with the tubular element (40), the at least one helical element (50, 50', 50") being able to force the flow of fluid coming out of the tubular element (40) to rise towards the top (102) of the tank (10) following a predetermined path.

L'invention concerne un dispositif (100) pour le traitement et le stockage temporaire de liquides, le dispositif (100) comprenant un réservoir (10), fonctionnant sous pression, conçu pour contenir et traiter un fluide destiné à la purification des eaux de ballast des navires ; une ouverture d'entrée (20) pour introduire de l'ozone, du peroxyde d'hydrogène et de l'eau de traitement à l'intérieur du réservoir (10) ; une ouverture de sortie (30) pour évacuer le fluide destiné à la purification des eaux de ballast hors du réservoir (10) ; un élément tubulaire (40), placé à l'intérieur du réservoir (10) et mis en communication fluidique avec l'ouverture d'entrée (20), l'élément tubulaire (40) étant conçu pour libérer le fluide destiné à la purification des eaux de ballast à proximité du fond (101) du réservoir (10). Le dispositif est caractérisé en ce qu'il comprend au moins un élément hélicoïdal (50, 50', 50") coaxial avec l'élément tubulaire (40), au moins un des éléments hélicoïdaux (50, 50', 50") étant apte à forcer l'écoulement du fluide sortant de l'élément tubulaire (40) à s'élever vers le haut (102) du réservoir (10) suivant un trajet prédéterminé.
