DESCRIZIONE DESCRIPTION
Attualmente esistono in commercio dispositivi per la sanificazione basati sull?emissione di raggi ultravioletti, la cui destinazione d?uso passa dalla sterilizzazione di acqua potabile, alla sanificazione di superfici, al trattamento dell?aria in sistemi di condizionamento, all?eliminazione di alghe negli acquari, al trattamento delle acque reflue, fino ad arrivare alla sanificazione di ambienti. Currently there are sanitizing devices on the market based on the emission of ultraviolet rays, whose intended use passes from the sterilization of drinking water, to the sanitization of surfaces, to the treatment of air in conditioning systems, to the elimination of algae in aquariums, waste water treatment, up to the sanitation of environments.
La radiazione ultravioletta ( UVGI ) ? un metodo che utilizza una breve lunghezza d'onda per inattivare i microrganismi, distruggendo acidi nucleici attraverso l?interruzione del DNA, rendendoli incapaci di svolgere le funzioni cellulari. Ultraviolet radiation (UVGI)? a method that uses a short wavelength to inactivate microorganisms, destroying nucleic acids through DNA disruption, rendering them unable to perform cellular functions.
A certe lunghezze d'onda, le radiazioni UV si rendono mutagene per batteri, virus e altri microrganismi. In particolare, a lunghezze d'onda intorno a 200 nm - 300 nm, l?UV rompe i legami molecolari all'interno DNA, producendo dimeri di timina che possono uccidere o disattivare gli organismi. Le sorgenti di UVC in commercio, attualmente, sono le seguenti: At certain wavelengths, UV radiation becomes mutagenic to bacteria, viruses and other microorganisms. Specifically, at wavelengths around 200nm - 300nm, UV breaks molecular bonds within DNA, producing thymine dimers that can kill or inactivate organisms. The sources of UVC currently on the market are the following:
? lampade al mercurio che emettono luce UV alla lunghezza d?onda di 253,7 nm. ? mercury lamps that emit UV light at a wavelength of 253.7 nm.
? LED UV che emettono luce UV a lunghezze d'onda selezionabili tra 255 e 280 nm. ? UV LEDs that emit UV light at wavelengths selectable between 255 and 280 nm.
? lampade allo xenon pulsato che emettono luce UV attraverso l'intero spettro con un picco di emissione vicino 230 nm. ? pulsed xenon lamps that emit UV light across the entire spectrum with an emission peak near 230 nm.
L'efficacia germicida dipende dal tempo di esposizione, dall'intensit? di irradiazione e dalla lunghezza d'onda della radiazione, dalla presenza di particelle che possono proteggere i microrganismi dai raggi UV, e dalla capacit? di un microrganismo di resistere alla radiazione. The germicidal efficacy depends on the exposure time, on the intensity? of irradiation and from the wavelength of the radiation, from the presence of particles that can protect microorganisms from UV rays, and from the capacity? of a microorganism to resist radiation.
In molti sistemi viene utilizzata la ridondanza nell'esporre i microrganismi ai raggi UV, facendo circolare l'aria o l'acqua ripetutamente, oppure aumentando il tempo di esposizione. In many systems, redundancy is used to expose microorganisms to UV rays, by circulating air or water repeatedly, or by increasing the exposure time.
Un metodo per misurare l'efficacia UV nelle applicazioni di disinfezione ? quello di calcolare la dose UV, ossia la quantit? di energia UV germicida assorbita da una popolazione microbica per un periodo di tempo, misurata generalmente in ?J/cm2 o, equivalentemente, in ?W*s/cm2. La Norma EN 60335-2-59 pubblica linee guida di dosaggio dei raggi UV per le applicazioni di trattamento dei microorganismi. A method to measure UV effectiveness in disinfection applications? to calculate the UV dose, ie the quantity? of germicidal UV energy absorbed by a microbial population over a period of time, generally measured in? J / cm2 or, equivalently, in? W * s / cm2. The EN 60335-2-59 standard publishes UV rays dosage guidelines for microorganism treatment applications.
Il trovato si prefigge lo scopo di sanificare/decontaminare da virus, batteri, alghe, acari o spore le persone nella loro interezza, comprese le calzature, gli abiti, gli accessori ed eventuali oggetti mobili. The purpose of the invention is to sanitize / decontaminate people in their entirety from viruses, bacteria, algae, mites or spores, including footwear, clothes, accessories and any movable objects.
In particolare, con riferimento alla figura allegata, il sistema ? costituito da una cabina a base circolare (1), sulla quale sono presenti numero due porte scorrevoli (2), movimentate da un servo-attuatore automatico contenuto all?interno del vano superiore (3). Una porta ? adibita all?entrata ed una all?uscita. Il sistema intelligente rileva la persona che si avvicina alla cabina di sanificazione/decontaminazione, la porta di ingresso si apre per permettere l?ingresso della persona. Quando la persona ? entrata nella cabina, la porta di ingresso si chiude, compaiono immagini per guidare la persona durante la fase di posizionamento e vengono emesse istruzioni vocali, viene quindi avviato il trattamento di sanificazione/decontaminazione. Tale trattamento ? eseguito per mezzo di opportune sorgenti UV (4), e per mezzo di sorgenti di ioni negativi posizionate all?interno del vano superiore. In particular, with reference to the attached figure, the? consisting of a car with a circular base (1), on which there are two sliding doors (2), moved by an automatic servo-actuator contained inside the upper compartment (3). A door ? used at the entrance and one at the exit. The intelligent system detects the person approaching the sanitation / decontamination cabin, the entrance door opens to allow the person to enter. When the person? entering the cabin, the entrance door closes, images appear to guide the person during the positioning phase and voice instructions are issued, the sanitization / decontamination treatment is then started. Such treatment? performed by means of suitable UV sources (4), and by means of negative ion sources positioned inside the upper compartment.
Alla fine del trattamento, si apre automaticamente la porta dedicata per permettere l?uscita della persona che ? stata sanificata/decontaminata. Dopo che la persona ? uscita dalla cabina di trattamento, la porta di uscita si richiude automaticamente. Finch? la porta di uscita non si ? completamente chiusa, la porta di ingresso non potr? aprirsi nuovamente. At the end of the treatment, the dedicated door opens automatically to allow the exit of the person who? been sanitized / decontaminated. After the person? exit from the treatment cabin, the exit door closes automatically. Finch? the exit door does not you? completely closed, the entrance door will not be able? open again.
Il sistema registra la temperatura della persona, la durata del trattamento, il livello di irraggiamento sulla persona, la dose di radiazione applicata, data e ora, numero di persone trattate giornalmente ed eventuali anomalie riscontrate. The system records the person's temperature, the duration of the treatment, the level of irradiation on the person, the dose of radiation applied, date and time, number of people treated daily and any anomalies found.
Le impostazioni del sistema, durata del trattamento, livello di irraggiamento sulla persona e dose di radiazione applicata possono essere programmate anche da remoto per mezzo di comunicazione Bluetooth o WiFi. Alla fine del trattamento le informazioni sono condivise con i sistemi informativi aziendali in logica Industria 4.0. The system settings, duration of treatment, level of irradiation on the person and dose of radiation applied can also be programmed remotely by means of Bluetooth or WiFi communication. At the end of the processing, the information is shared with the company information systems according to Industry 4.0 logic.
Le sorgenti disponibili attualmente sul mercato hanno un ampio spettro di emissione compreso tra i 200 ? 300 nm. Non ? possibile utilizzare questo tipo di sorgenti in presenza di persone e/o animali oltre una certa dose di radiazioni UV, come specificato dal D.Lgs. 81 in materia di sicurezza sul lavoro. Restringendo la banda di emissione nel range compreso tra 200 ? 240 nm tali radiazioni non penetrano nella cute e nella cornea e quindi possono essere utilizzate per l?inattivazione di virus, batteri, spore, acari e alghe in presenza delle persone. The sources currently available on the market have a broad spectrum of emissions between 200? 300 nm. Do not ? It is possible to use this type of sources in the presence of people and / or animals over a certain dose of UV radiation, as specified by Legislative Decree 81 regarding workplace safety. By narrowing the emission band in the range between 200? 240 nm these radiations do not penetrate the skin and cornea and therefore can be used for the inactivation of viruses, bacteria, spores, mites and algae in the presence of people.
