Abstract

Il est divulgué un appareil et un procédé de génération d'oxygène autonome. L'appareil de génération d'oxygène autonome divulgué comprend : un contenant de génération d'oxygène contenant un matériau cible de réaction ; un contenant de catalyseur introduit dans le récipient de génération d'oxygène et contenant un catalyseur pour la génération d'oxygène ; et une unité de séparation d'oxygène située à l'intérieur du contenant de génération d'oxygène. Le contenant de catalyseur comprend : un corps de contenant de catalyseur creux dans lequel le catalyseur est reçu ; et une ouverture formée sur un côté du corps de contenant de catalyseur pour maintenir une surface de contact constante entre le catalyseur et le matériau cible de réaction. De plus, le procédé de génération d'oxygène autonome divulgué comprend les étapes consistant à : recevoir un catalyseur pour la génération d'oxygène dans un contenant de catalyseur ; introduire le contenant de catalyseur dans un contenant de génération d'oxygène ; provoquer une réaction entre le catalyseur et un matériau cible de réaction tout en maintenant une surface de contact constante entre ceux-ci à travers une ouverture ; et générer de l'oxygène par l'intermédiaire de la réaction tout en régulant de manière stable le taux de réaction. Par conséquent, l'effet de stabilisation de la quantité de génération d'oxygène peut être obtenu par régulation stable du taux de réaction entre le catalyseur et la solution de peroxyde d'hydrogène.
