Abstract

Cet appareil d'alimentation en agent chimique solide est un appareil dans lequel un agent chimique est élué dans l'eau brute fournie par une pompe. L'appareil d'alimentation en agent chimique solide possède un orifice d'admission d'eau et un orifice d'évacuation d'eau dans une partie de base, et possède un boîtier ayant un couvercle de boîtier et disposé dans une partie supérieure de l'appareil. Un récipient cylindrique qui divise le boîtier en un côté circonférentiel interne et un côté circonférentiel externe, et un conduit qui relie l'orifice d'admission d'eau et la surface inférieure du récipient cylindrique sont aménagés à l'intérieur du boîtier. Le récipient cylindrique comporte une paroi de séparation. La paroi de séparation sépare l'intérieur du récipient cylindrique en parties supérieure et inférieure, et permet à l'eau brute de traverser. Un produit chimique solide hydrosoluble peut être placé sur la surface supérieure de la paroi de séparation. Un orifice d'évacuation traversant la surface latérale du récipient cylindrique est aménagé sur la surface latérale du récipient cylindrique de façon à se trouver au-dessus de la paroi de séparation. Une partie de bord s'étendant à partir de la surface latérale du récipient cylindrique est aménagée sur la surface inférieure du récipient cylindrique. L'appareil d'alimentation en agent chimique solide, dans lequel un agent chimique peut être élué de façon stable même après une utilisation à long terme, peut être incorporé dans un système de traitement d'eau.
