Abstract

Le dispositif de traitement et de purification d'air par photocatalyse concerné comprend : - un caisson dont la paroi inférieure (10) présente au moins une ouverture d'aspiration d'air au niveau d'une zone de périphérie de cette paroi inférieure (10) et au moins une première ouverture de soufflage d'air sur cette même paroi inférieure (10), située au niveau de la zone de périphérie opposée à l'ouverture d'aspiration d'air ; le caisson contient au moins un ventilateur apte à créer un flux d'air entre lesdites ouvertures ainsi qu'au moins un système de photocatalyse situé sur ce flux d'air et apte à traiter ce flux d'air ; - un système d'éclairage (14) situé au niveau de la paroi inférieure du caisson, côté extérieur de celui-ci, entre lesdites ouvertures, et - des moyens de fixation (9) permettant l'installation du dispositif sur un plafond ou un faux plafond. Figure pour l’abrégé : Fig. 3The device for treating and purifying air by photocatalysis in question comprises: - a box whose lower wall (10) has at least one air suction opening at a peripheral zone of this lower wall (10) and at least one first air blowing opening on this same lower wall (10), located at the peripheral zone opposite the air suction opening; the box contains at least one fan capable of creating an air flow between said openings as well as at least one photocatalysis system located on this air flow and capable of treating this air flow; - a lighting system (14) located at the lower wall of the box, on the outside thereof, between said openings, and - fixing means (9) allowing the device to be installed on a ceiling or a false ceiling.
