Abstract

La présente invention concerne un dispositif de stérilisation/purification d'air pour détecter un photocatalyseur, qui induit une photoactivation à large bande, et l'intensité/le degré de photoénergie émise vers le photocatalyseur, de façon à laisser un temps approprié pour gérer des lampes de stérilisation et un temps approprié pour remplacer celle-ci. À proximité d'un emplacement d'entrée primaire d'air contaminé, un premier module de filtre à photocatalyseur et un capteur de luminance primaire sont agencés, et un deuxième module de filtre à photocatalyseur et un capteur de luminance secondaire sont agencés. Le premier module de filtre à photocatalyseur comprend une lampe de stérilisation primaire et un photocatalyseur de type bille de céramique combinés dans un module unique. Le capteur de luminance primaire est installé entre la lampe de stérilisation primaire et le photocatalyseur de bille de céramique de façon à détecter/réguler la quantité de lumière émise par la lampe de stérilisation. Le deuxième module de filtre à photocatalyseur comprend une lampe de stérilisation secondaire et un filtre à photocatalyseur à milieu de type réseau combinés dans un module unique. Le capteur de luminance secondaire est installé entre la lampe de stérilisation secondaire et le filtre à photocatalyseur à milieu de type réseau de façon à détecter/réguler la quantité de lumière émise par la lampe de stérilisation. En conséquence, une intensité appropriée de photoénergie est détectée et régulée de façon à éviter la dégradation de la photoactivité du premier filtre à photocatalyseur et du deuxième filtre à photocatalyseur, de façon à améliorer les performances de purification, et un temps approprié pour gérer les lampes de stérilisation et un temps approprié pour remplacer celles-ci sont obtenus. La configuration à deux étages des premier et deuxième modules de filtre à photocatalyseur améliore efficacement les performances de stérilisation/purification et, même si l'un d'entre eux ne présente pas des performances normales, évite une dégradation rapide des performances de stérilisation/purification. Une technologie de commande est appliquée de sorte que, lorsque le colmatage d'un filtre à photocatalyseur par des micropoussières en suspension augmente la pression de ventilation et dégrade la quantité de ventilation, le nombre de rotations du ventilateur varie en fonction de la pression de ventilation. En conséquence, lorsque la pression de ventilation augmente, le nombre de rotations du ventilateur est augmenté pour maintenir la quantité appropriée de ventilation et, lorsque le nombre de rotations du ventilateur augmente et dépasse un nombre prédéterminé, le fonctionnement du ventilateur est arrêté, de façon à fournir une fonction de détection et de régulation du temps disponible pour remplacer les filtres à photocatalyseur.
