Abstract

L'invention concerne un agencement pour l'ajout de dioxyde de chlore (ClO2) dans de l'eau (H2O), comprenant une première conduite d'alimentation (5a) pour l'introduction d'un premier composant réactionnel (HCl), une seconde conduite d'alimentation (5b) pour l'introduction d'un second composant réactionnel (NaClO2) et un tube de mélange (7) pour le mélange et la mise en réaction des deux composants réactionnels pour former du dioxyde de chlore, les deux conduites d'alimentation (5a, 5b) débouchant dans le tube de mélange (7) et le tube de mélange (7) étant agencé coaxialement dans une conduite d'eau (8) conduisant l'eau à enrichir en dioxyde de chlore. Son objectif est de proposer une configuration concrète d'un agencement générique à faible consommation de produits chimiques. La configuration doit par ailleurs permettre de mettre à niveau des conduites d'eau existantes avec un agencement pour l'ajout de dioxyde de chlore dans l'eau (H2O) conduite par la conduite d'eau (8). Cet objectif est atteint par un disque à bride annulaire essentiellement plat (1), à partir de la périphérie duquel les deux conduites d'alimentation (5a, 5b) s'étendent vers le centre du disque à bride (1) et y débouchent dans le tube de mélange (7), le tube de mélange (7) s'étendant à partir de celles-ci perpendiculairement au plan (E) du disque à bride (1), étant fermé à son extrémité proximale à l'exception des ouvertures (6) de la conduite d'alimentation (5a, 5b) et étant ouvert à son extrémité distale, la conduite d'eau (8) comprenant deux sections de conduite (8a, 8b) reliées par un raccord à bride (9) et le disque à bride (1) étant fixé dans le raccord à bride (9).
