Title
(EN) AIR FILTRATION DEVICE
(FR) DISPOSITIF DE FILTRATION D'AIR
Abstract
(EN)
An air filtration device (1) comprising a filling (2) supporting microorganisms and plants (20), a forced air circulation system (3) provided with at least one air suction or blowing mouth (4), and a water circulation circuit (5). The filling (2) is associated with a shaper (6) for forming a vertical continuous filtering wall (7) partially delimiting a cavity (8), the device (1) comprising means for closing the cavity (8) comprising a closing wall (101) provided with the mouth (4) and in bearing contact with said continuous filtering wall (7). The shaper (6) comprises two permeable membranes (61, 63) each forming, with a frame (62, 64), the inner face (71) and outer face (72) of said continuous filtering wall (7), the filling (2) formed from a mass of organic and/or mineral elements being interposed between said membranes, the outer membrane (63) receiving the plants (20).
(FR)
Dispositif (1) de filtration d'air comprenant un garnissage (2) support de microorganismes et de végétaux (20), un système (3) de circulation forcée d'air muni d'au moins une bouche (4) d'aspiration ou de soufflage d'air, et un circuit (5) de circulation d'eau. Le garnissage (2) est associé à un conformateur (6) pour former une paroi (7) continue filtrante verticale délimitant partiellement une cavité (8), le dispositif (1) comprend des moyens de fermeture de la cavité (8) comprenant une paroi (101) de fermeture munie de la bouche(4) et en contact d'appui avec ladite paroi (7) continue filtrante.Le conformateur (6)comprend deux membranes(61,63)perméables formant chacune avec une armature (62, 64), les faces interne (71) et externe (72) de ladite paroi (7) continue filtrante, le garnissage (2) formé d'un amas d'éléments organiques et/ou minéraux étant interposé entre lesdites membranes, la membrane extérieure (63) recevant les végétaux (20).
