Abstract

La présente invention étend, en utilisant un moyen d'extension de surface (30), la surface d'une solution de dioxyde de chlore stabilisée (10) qui est irradiée avec des rayons ultraviolets (71) et conservée dans un réservoir de stockage (20), génère rapidement du dioxyde de chlore gazeux et libère le gaz à l'extérieur du récipient en utilisant des moyens de ventilation (61). Le dioxyde de chlore gazeux est libéré de manière stable en irradiant avec des rayons ultraviolets le dioxyde de chlore liquide stabilisé. Il est possible d'ajuster la concentration du dioxyde de chlore gazeux généré en ajustant la concentration de la solution de dioxyde de chlore stabilisée (10) et la puissance des rayons ultraviolets (71). En libérant directement du dioxyde de chlore gazeux faiblement concentré sans danger pour les occupants à l'intérieur d'une pièce habitée, il est possible de stériliser l'intérieur de la pièce d'un coin à l'autre. Lorsque sa concentration est élevée, il est possible de stériliser un dispositif médical à l'intérieur d'une boîte de stérilisation pour dispositifs médicaux. Par conséquent, il est possible de fournir un dispositif générateur de dioxyde de chlore gazeux pour générer rapidement et en continu du dioxyde de chlore gazeux et gérer facilement la concentration de dioxyde de chlore gazeux.
