Title (EN) GAS INJECTOR FOR HYPOCHLOROUS ACID REACTOR
(FR) INJECTEUR DE GAZ POUR REACTEURS DE PRODUCTION D'ACIDE HYPOCHLOREUX
Abstract:
(EN) An elongated, generally vertically extending cocurrent reactor vessel (15) for the production of hypochlorous acid by the mixing and reaction of a liquid alkali metal hydroxide and a gaseous halogen is provided wherein a nozzle (21) is mounted near the top (14) of the reactor vessel (15) beneath the gas injector (12) to spray the liquid alkali metal hydroxide in droplets so that the halogen gas can be absorbed into the surface of the droplets simultaneously with water evaporation in the vessel. The vessel (15) has a spraying and reaction zone (25) immediately beneath the atomizer (21) and a drying zone (26) beneath the spraying and reaction zone.
(FR) Une cuve de réaction (15) allongée, généralement verticale, à courants parallèles utilisée pour produire de l'acide hypochloreux par mélange et réaction d'un hydroxyde liquide d'un métal alcalin et d'un halogène gazeux, comprend un ajutage (21) monté près de la partie supérieure (14) de la cuve de réaction (15), en-dessous de l'injecteur de gaz (12), qui vaporise l'hydroxyde liquide de métal alcalin sous forme de gouttelettes, de sorte que le gaz halogène puisse s'absorber dans la surface des gouttelettes en même temps que l'eau s'évapore dans la cuve. La cuve (15) comprend une zone de vaporistation et de réaction (25) située immédiatement en-dessous de l'atomiseur (21) et une zone de séchage (26) en-dessoous de la zone de vaporisation et de réaction.
