Abstract
L'INVENTION VISE UN DISPOSITIF DE FILTRAGE POUR L'AIR RENFERME DANS UN LOCAL. CE DISPOSITIF COMPREND UN RECIPIENT AVEC UN COUVERCLE RABATTABLE QUI EST INSERE DANS LE SYSTEME DE CANAUX D'AERATION ET DANS LEQUEL SONT PLACES DES ELEMENTS FILTRANTS EN CHARBON ACTIF, EN LITHINE OU EN D'AUTRES PRODUITS CHIMIQUES, CES ELEMENTS FILTRANTS ETANT REALISES SOUS FORME DE CARTOUCHES CYLINDRIQUES ANNULAIRES OU EN FORME DE PLAQUES ET QUI PEUVENT ETRE ECHANGEES ET DISPOSEES SEPAREMENT. LE DISPOSITIF DE FILTRAGE S'APPLIQUE DANS LES INSTALLATIONS SERVANT A LA DECONTAMINATION ET L'EPURATION DE L'ATMOSPHERE DANS DES LOCAUX ISOLES OU IL FACILITE LE RECHANGE DES ELEMENTS FILTRANTS.THE INVENTION AIMS AT A FILTERING DEVICE FOR THE AIR CONTAINED IN A ROOM. THIS DEVICE INCLUDES A CONTAINER WITH A HINGED LID WHICH IS INSERTED IN THE SYSTEM OF AERATION CHANNELS AND IN WHICH ARE PLACED FILTER ELEMENTS IN ACTIVE CARBON, LITHIN OR OTHER CHEMICALS, THESE FILTER ELEMENTS BEING MADE IN THE FORM OF CYLINDRICAL, ANNULAR OR PLATE-SHAPED CARTRIDGES, WHICH CAN BE EXCHANGED AND ARRANGED SEPARATELY. THE FILTERING DEVICE IS APPLIED IN INSTALLATIONS SERVING THE DECONTAMINATION AND PURIFICATION OF THE ATMOSPHERE IN ISOLATED PREMISES WHERE IT MAKES THE REPLACEMENT OF FILTER ELEMENTS EASIER.
