dal titolo: ?APPARECCHIO SANIFICATORE PER ARIA AMBIENTALE? entitled:? SANITIZER FOR ROOM AIR?
DESCRIZIONE DESCRIPTION
L'invenzione si riferisce ad un apparecchio sanificatore per aria ambientale. The invention refers to a sanitizing device for ambient air.
L?anno 2020 sar? ricordato senza dubbio solo per il coronavirus e le sue vittime. Il derivante caos sanitario a livello mondiale ha imposto alle popolazioni l?uso prolungato di mascherine facciali e l?adozione di misure di sicurezza per prevenire il contagio, soprattutto nei posti di lavoro o aggregazione. Di fronte a questo nuovo scenario di convivenza sociale, ? necessario risolvere il problema di coniugare la necessit? di mantenere vivo il sistema economico produttivo con l?incolumit? personale. The year 2020 will be undoubtedly remembered only for the coronavirus and its victims. The resulting global health chaos has forced populations to wear face masks for a long time and to adopt safety measures to prevent contagion, especially in workplaces or gathering places. Faced with this new scenario of social coexistence, ? necessary to solve the problem of combining the need? to keep alive the productive economic system with the? safety? personal.
Risolvere o mitigare il suddetto problema ? lo scopo principale dell'invenzione, la quale ? definita nelle allegate rivendicazioni, in cui quelle dipendenti definiscono varianti vantaggiose. Fix or mitigate the above problem? the main purpose of the invention, which is defined in the attached claims, wherein the dependent ones define advantageous variants.
Si propone un apparecchio sanificatore di aria ambientale per eliminare virus e batteri. L?apparecchio comprende We propose an ambient air sanitizing device to eliminate viruses and bacteria. The appliance includes
un percorso per un flusso d?aria da sanificare a path for an air flow to be sanitized
un filtro (anche di tipo EPA) posto per intercettare il flusso d?aria e filtrarlo a filter (also of the EPA type) placed to intercept the air flow and filter it
una sorgente di radiazione, ad es. UV e/o UV-C (UV germicida), per irradiare il lato del filtro in cui il flusso d?aria penetra nel filtro e ivi uccidere virus e/o batteri. a radiation source, e.g. UV and/or UV-C (germicidal UV), to irradiate the side of the filter where the airflow enters the filter and kill viruses and/or bacteria there.
L?inattivazione dei virus e batteri ? fortemente influenzato dal tempo di esposizione alla luce UVC quindi un passaggio veloce di agenti patogeni attraverso la sorgente UVC potrebbe essere insufficiente ad ottenere una sterilizzazione dell?aria convogliata. Poich? i virus tendono in particolare a legarsi ed essere trasportati assieme al pulviscolo, alle goccioline di acqua/saliva e/o agli inquinanti presenti nell?aria, ? vantaggioso filtrarli e bloccati ad esempio sulla superficie di un filtro, ad es. anche HEPA. The inactivation of viruses and bacteria? strongly influenced by the exposure time to the UVC light therefore a fast passage of pathogens through the UVC source could be insufficient to obtain a sterilization of the conveyed air. because viruses tend in particular to bind and be transported together with dust, droplets of water/saliva and/or pollutants present in the air, ? advantageous to filter them and blocked for example on the surface of a filter, e.g. also HEPA.
Il vantaggio di mettere una sorgente di radiazione a monte del filtro ? che il filtro rimane pulito e senza depositi di batteri. Siccome sulla superficie del filtro colpita dal flusso d?aria si possono fermare agenti patogeni, tale superficie viene irradiata per lungo tempo creando condizioni ideali per inattivare virus e batteri. Quindi il flusso d?aria filtrato rimane sanificato in modo sicuro e continuo. Si evita cio? il noto fenomeno di accumulo nocivo che avviene nei filtri dei condizionatori domestici. The advantage of placing a radiation source upstream of the filter? that the filter remains clean and without bacteria deposits. Since pathogenic agents can stop on the surface of the filter affected by the air flow, this surface is irradiated for a long time creating ideal conditions for inactivating viruses and bacteria. So the filtered airflow remains sanitized safely and continuously. Is this avoided? the well-known phenomenon of harmful accumulation that occurs in the filters of domestic air conditioners.
Un altro vantaggio della combinazione di una sorgente di radiazione e di un filtro a valle della sorgente di radiazione ? che l?azione filtrante diventa molto pi? efficace. Siccome per eliminare i batteri conta il tempo di esposizione alla sorgente di radiazione, il filtro li trattiene per un tempo sufficiente affinch? la sorgente di radiazione renda inattiva la carica virale/batterica. Another advantage of the combination of a radiation source and a filter downstream of the radiation source? that the filtering action becomes much more? effective. Since the time of exposure to the radiation source counts to eliminate bacteria, the filter retains them for a sufficient time so that they are released. the radiation source inactivates the viral/bacterial load.
In una variante preferita, l?apparecchio comprende una seconda sorgente di radiazione per irradiare il lato del filtro in cui il flusso d?aria esce dal filtro e ivi uccidere virus e/o batteri.. La seconda sorgente di radiazione migliora l?azione battericida dell?apparecchio e a qualit? dell?aria che esce dall?apparecchio, e preferibilmente ? una sorgente di radiazione UV e/o UV-C (UV germicida). In a preferred variant, the apparatus comprises a second radiation source for irradiating the side of the filter where the air flow exits the filter and killing viruses and/or bacteria there. The second radiation source improves the bactericidal effect of the appliance and quality of the air that comes out of the appliance, and preferably ? a source of UV and/or UV-C (germicidal UV) radiation.
In una variante preferita, l?apparecchio comprende un involucro esterno che delimita detto percorso per il flusso d?aria. Tale percorso allora si estende in una cavit? interna dell?involucro, e inizia su una presa d?aria posta sulla superficie dell?involucro e termina su una uscita d?aria posta sulla superficie dell?involucro. In a preferred variant, the apparatus comprises an outer casing which delimits said path for the air flow. This path then extends into a cavity? internal part of the casing, and begins on an air intake placed on the surface of the casing and ends on an air outlet placed on the surface of the casing.
L?apparecchio comprende preferibilmente una ventola o mezzi per creare una portata forzata di aria costituente detto flusso. In particolare la ventola o detti mezzi sono montati dentro l?involucro, per compattezza e massima efficienza di portata di flusso d?aria, oppure sono montati all?esterno dell?involucro. The apparatus preferably comprises a fan or means for creating a forced flow of air constituting said flow. In particular, the fan or said means are mounted inside the casing, for compactness and maximum efficiency of the air flow rate, or they are mounted outside the casing.
L?apparecchio comprende preferibilmente un pre-filtro posto, rispetto alla direzione di avanzamento del flusso d?aria, a monte della sorgente di irradiazione che irradia il lato (del filtro) che il flusso d?aria penetra. The apparatus preferably comprises a pre-filter placed, with respect to the direction of advancement of the air flow, upstream of the source of radiation which irradiates the side (of the filter) that the air flow penetrates.
Una o ciascuna sorgente di radiazione pu? essere ad es. One or each radiation source can be eg.
? una lampada UV e/o UV-C e/o un diodo led con luce emessa a frequenza UV e/o UV-C, preferibilmente coadiuvata anche da un filtro (anche di tipo HEPA); e/o ? a UV and/or UV-C lamp and/or a LED diode with light emitted at a UV and/or UV-C frequency, preferably also assisted by a filter (also of the HEPA type); and/or
? una lampada o diodo laser UV, in particolare UV-C, e/o ? a UV lamp or laser diode, in particular UV-C, and/or
? montata dentro l?involucro o sulla superficie esterna dell?involucro; e/o ? mounted inside the casing or on the external surface of the casing; and/or
? montata dentro l?involucro, installata nella cavit? interna. In questo caso anche il filtro per intercettare il flusso d?aria e filtrarlo ? installato dentro la cavit?. ? mounted inside the casing, installed in the cavity? internal. In this case also the filter to intercept the flow of air and filter it? installed inside the cavity?.
Una lampada o diodo laser UV, in particolare UV-C, determinano un deciso abbattimento (anche oltre il 90%) di virus (H1N1), virus A influenza, compreso il Covid 19. A UV lamp or laser diode, in particular UV-C, determine a decisive reduction (even over 90%) of viruses (H1N1), influenza A viruses, including Covid 19.
Un altro aspetto dell?invenzione riguarda un metodo per sanificare aria ambientale onde eliminare virus e batteri. Il metodo prevede di Another aspect of the invention concerns a method for sanitizing ambient air in order to eliminate viruses and bacteria. The method involves
realizzare un percorso per un flusso d?aria da sanificare, create a path for an air flow to be sanitized,
intercettare il flusso d?aria e filtrarlo con un filtro (anche di tipo EPA), intercept the air flow and filter it with a filter (also of the EPA type),
irradiare il lato del filtro in cui il flusso d?aria penetra il filtro con una sorgente di radiazione per ivi uccidere virus e/o batteri. irradiate the side of the filter where the airflow enters the filter with a radiation source to kill viruses and/or bacteria there.
Il metodo condivide tutte le varianti esposte per l?apparecchio. The method shares all the variants shown for the device.
I vantaggi dell?invenzione saranno pi? chiari dalla seguente descrizione di una preferita forma realizzativa di apparecchio, riferimento facendo all?allegato disegno in cui ? Fig. 1 mostra una vista tridimensionale di un apparecchio sanificatore. The advantages of the invention will be more? clear from the following description of a preferred embodiment of the apparatus, with reference to the enclosed drawing in which ? Fig. 1 shows a three-dimensional view of a sanitizing device.
Un apparecchio sanificatore 10 ? qui illustrato in fig. 1 e comprende un involucro esterno cavo 12 che delimita internamente una cavit? 20. A sanitizing appliance 10 ? illustrated here in fig. 1 and comprises a hollow outer casing 12 which internally delimits a cavity? 20.
Un lato dell?involucro 12 comprende una griglia 14 per aspirare un flusso d?aria esterna F e introdurlo dentro l?involucro 12. Allo scopo l?apparecchio sanificatore 10 ? dotato di una ventola 50 che induce il flusso d?aria forzato F (indicato da frecce) verso la griglia 14 e lo fa uscire da un?altra griglia 16. One side of the casing 12 comprises a grille 14 for sucking in an external air flow F and introducing it into the casing 12. For this purpose, the sanitizing device 10 is ? equipped with a fan 50 which induces the forced air flow F (indicated by arrows) towards the grid 14 and makes it exit from another grid 16.
Il flusso F attraversa allora l?involucro 12, e durante il suo percorso dentro l?involucro 12 incontra in sequenza: The flow F then crosses the casing 12, and during its journey inside the casing 12 it encounters in sequence:
una prima lampada UVC 30, a first UVC 30 lamp,
un filtro 32 (anche tipo HEPA), e a 32 filter (also HEPA type), e
una seconda lampada UVC 34. a second UVC 34 lamp.
La prima lampada UVC 30 irradia il filtro 32 sul lato di ingresso del flusso F. La seconda lampada UVC 30 irradia il filtro 32 sul lato di uscita del flusso F. The first UVC lamp 30 irradiates the filter 32 on the inlet side of the flow F. The second UVC lamp 30 irradiates the filter 32 on the outlet side of the flux F.
Quindi il flusso d?aria F viene prelevato dall?ambiente, e durante l?avanzamento dentro l?involucro 12 viene decontaminato dalle lampade 30, 34. La lampada 30 garantisce la pulizia del filtro 32 eliminando l?accumulo di batteri sul filtro 32. Il filtro 32 rallenta e trattiene i batteri affinch? le lampade 30, 34 possano ucciderli. La lampada 35 garantisce la sanificazione del flusso F all?uscita del filtro 32 eliminando la minoranza di batteri che il filtro 32 non ha trattenuto. Then the air flow F is drawn from the environment, and during its advance inside the enclosure 12 it is decontaminated by the lamps 30, 34. The lamp 30 guarantees the cleaning of the filter 32 by eliminating the accumulation of bacteria on the filter 32. The 32 filter slows down and retains the bacteria so that? lamps 30, 34 can kill them. The lamp 35 ensures the sanitization of the flow F at the outlet of the filter 32 by eliminating the minority of bacteria which the filter 32 has not retained.
Preferibilmente la portata del flusso d?aria F viene regolato controllando il regime della ventola 50 tramite un processore (non mostrato). Preferably the airflow rate F is adjusted by controlling the speed of the fan 50 via a processor (not shown).
