Abstract

Le dispositif de traitement et de purification d'air concerné comprend : - deux caissons placés l'un dans l'autre, à savoir : un caisson extérieur ayant une face dite "centrale" attenante à des faces latérales formant quatre côtés du caisson par rapport à cette face centrale ; la face centrale présente une ouverture d'aspiration et les quatre faces latérales présentent des ouvertures (4) de soufflage d'air par lesquelles l'air est soufflé hors du caisson de façon à créer un effet Coanda ; le caisson intérieur présente une ouverture d'entrée d'air en regard de ladite ouverture d'aspiration du caisson extérieur et une ouverture de sortie d'air ; - des éléments (8, 12) de filtration de l'air, des éléments (9, 14) de photocatalyse et un ventilateur (20) contenus dans le caisson intérieur entre lesdites ouvertures d'entrée d'air et de sortie d'air. Figure pour l’abrégé : Fig. 11The air treatment and purification device concerned comprises: - two boxes placed one inside the other, namely: an outer box having a so-called "central" face adjoining lateral faces forming four sides of the box with respect to to this central face; the central face has a suction opening and the four side faces have air blowing openings (4) through which air is blown out of the box so as to create a Coanda effect; the inner box has an air inlet opening facing said suction opening of the outer box and an air outlet opening; - air filtration elements (8, 12), photocatalysis elements (9, 14) and a fan (20) contained in the inner box between said air inlet and air outlet openings .
