Abstract[English]
The object of the invention is a nanofiltration device for inactivating droplet- transmitted pathogens. The microdroplets are captured by filtering contaminated air on a filter material/paper with the nanoflbrillated cellulose and/or nanocellulose surface treatment containing antiseptic metal ions and an adjuvant in the retained residual water. The air is sucked into the openings of the nanofiltration device located at the bottom passes Into the center of the filter cartridge, in which a germicidal emitter emits radiation In the UV-C range of the electromagnetic wavelength spectrum is mounted. Subsequently, it flows through a filter paper containing salts of antiseptic metals, from the center from the radiator outwards through a filter paper hermetically inserted into the filter cartridge, folded harmoniously so that its surface is maximally and entirely irradiated with UV-C radiation. Antiseptic ions diffuse into the contaminated microdroplets, which with UV-C radiation deactivate viruses and disinfect bacteria. Subsequently, the droplets dry out, and the deactivated viruses and bacteria are carried away by air, which, with the help of adjuvants, receive the human body and increase the population's immunity.[French]
L'objet de l'invention est un dispositif de nano-filtration pour inactiver des agents pathogènes transmis par gouttelettes. Les microgouttelettes sont capturées par filtration d'air contaminé sur un matériau/papier filtrant avec la cellulose nanofibrillée et/ou le traitement de surface de nanocellulose contenant des ions métalliques antiseptiques et un adjuvant dans l'eau résiduelle retenue. L'air est aspiré dans les ouvertures du dispositif de nanofiltration situé au fond passe dans le centre de la cartouche filtrante, dans lequel un émetteur germicide émet un rayonnement dans la plage UV-C du spectre de longueur d'onde électromagnétique est monté. Ensuite, il s'écoule à travers un papier filtrant contenant des sels de métaux antiseptiques, depuis le centre du radiateur vers l'extérieur à travers un papier filtrant inséré hermétiquement dans la cartouche filtrante, plié harmonieusement de telle sorte que sa surface est irradiée au maximum et entièrement avec un rayonnement UV-C. Les ions antiseptiques se diffusent dans les microgouttelettes contaminées qui, avec le rayonnement UV-C, désactivent les virus et désinfectent les bactéries. Ensuite, les gouttelettes sèches, et les virus et les bactéries désactivés sont emportés par l'air, ce qui, à l'aide d'adjuvants, reçoit le corps humain et augmente l'immunité de la population.
