DESCRIZIONE DESCRIPTION
La presente invenzione ha per oggetto un sistema per l'individuazione del livello di inquinamento di un ambiente indoor in riferimento a composti catalizzabili mediante nanotecnologie foto catalitiche. Le nanotecnologie foto catalitiche principalmente a base di biossido di titanio nano strutturato producono sollecitati da radiazione UV radicali che catalizzano al contatto sostanze organiche come virus, germi e alcune molecole organiche nocive per l'uomo fra cui benzene, toluene, formaldeide, monossido di carbonio, biossido di zolfo e biossido di azoto. The present invention relates to a system for identifying the pollution level of an indoor environment with reference to compounds that can be catalysed by photo-catalytic nanotechnologies. Photo-catalytic nanotechnologies mainly based on nano-structured titanium dioxide produce radicals stressed by UV radiation that catalyze organic substances such as viruses, germs and some organic molecules harmful to humans including benzene, toluene, formaldehyde, carbon monoxide, sulfur dioxide and nitrogen dioxide.
Secondo quanto noto, l'attività foto catalitica del biossido di titanio à ̈ in grado di catalizzare importanti molecole nocive come il biossido o azoto, i VOC (composti volatili organici quali formaldeide ,toluene,benzene) e il monossido di carbonio in sostanze non nocive per l'uomo come biossido di carbonio e inerti. As is known, the photo-catalytic activity of titanium dioxide is able to catalyze important harmful molecules such as dioxide or nitrogen, VOCs (volatile organic compounds such as formaldehyde, toluene, benzene) and carbon monoxide into harmless substances. for humans as carbon dioxide and inert materials.
In particolare, la presente invenzione trova applicazione in centri commerciali o negozi in genere, scuole, ospedali, studi medici e dentistici . In particular, the present invention finds application in shopping centers or shops in general, schools, hospitals, medical and dental offices.
La recente diffusione delle nanotecnologie attive rende perciò necessaria la presenza di uno strumento che possa rilevare il livello di inquinamento indoor nano-catalizzabile e monitorare l'azione della fotocatalisi. The recent diffusion of active nanotechnologies therefore makes it necessary to have an instrument that can detect the level of nano-catalysable indoor pollution and monitor the action of photocatalysis.
I sistemi attuali effettuano un monitoraggio di VOC, CO (monossido di carbonio) ,N02 (biossido di azoto) e S02 (biossido di zolfo) non affine ad applicazioni fotocatalitiche della nanotecnologia. Un esempio di stato dell'arte relativo ai sistemi di rilevazione degli inquinanti à ̈ rappresentato dal patent GB 2420616 dal titolo "Personal pollution monitor" . Current systems monitor VOC, CO (carbon monoxide), N02 (nitrogen dioxide) and S02 (sulfur dioxide) not related to photocatalytic applications of nanotechnology. An example of the state of the art relating to pollutant detection systems is represented by patent GB 2420616 entitled "Personal pollution monitor".
In questo contesto, il compito tecnico alla base della presente invenzione à ̈ proporre un sistema per la determinazione del livello di inquinamento indoor fotocatalizzabile mediante nanotecnologie e del monitoraggio della fotocatalisi stessa. In this context, the technical task underlying the present invention is to propose a system for determining the level of indoor pollution that can be photocatalyzed by means of nanotechnologies and for monitoring the photocatalysis itself.
In particolare, Ã ̈ scopo della presente invenzione mettere a disposizione un sistema che determini tale rischio analizzando e correlando le informazioni dei sensori VOC, monossido di carbonio, gas esausti (biossido di azoto e biossido di zolfo) e del sensore fotoelettrico. In particular, it is an object of the present invention to provide a system that determines this risk by analyzing and correlating the information of the VOC, carbon monoxide, exhaust gas (nitrogen dioxide and sulfur dioxide) sensors and of the photoelectric sensor.
II compito tecnico precisato e lo scopo specificato sono sostanzialmente raggiunti da un sistema per il monitoraggio del livello di inquinamento indoor foto catalizzabile mediante nanotecnologia attiva comprendente le caratteristiche tecniche esposte in una o più delle unite rivendicazioni. The specified technical task and the specified purpose are substantially achieved by a system for monitoring the level of photo-catalysable indoor pollution by means of active nanotechnology comprising the technical characteristics set out in one or more of the appended claims.
Ulteriori caratteristiche e vantaggi della presente invenzione appariranno maggiormente chiari dalla descrizione indicativa, e pertanto non limitativa, di una forma di realizzazione preferita ma non esclusiva di un sistema di monitoraggio di ambienti indoor, come illustrato nell'unita figura 1 che à ̈ una rappresentazione schematica di un sistema in accordo con la presente invenzione. Further characteristics and advantages of the present invention will become clearer from the indicative, and therefore non-limiting, description of a preferred but not exclusive embodiment of an indoor environment monitoring system, as illustrated in the unit Figure 1 which is a schematic representation of a system in accordance with the present invention.
Il sistema di monitoraggio dell'inquinamento fotocatalizzabile mediante nanotecnologia in accordo con la presente invenzione à ̈ applicabile in ogni caso entro un'area delimitata chiusa o aperta. A titolo di esempio, tale area delimitata può essere quella di un centro commerciale, di una aula di una scuola, di una sala operatoria, di una galleria stradale. The photocatalizable pollution monitoring system by means of nanotechnology in accordance with the present invention is applicable in any case within a closed or open delimited area. By way of example, this delimited area can be that of a shopping center, a classroom in a school, an operating room, a road tunnel.
Il metodo prevede, in via preliminare, di associare a ciascun inquinante 1 rilevato nell'area delimitata "A" un corrispondente valore. The method provides, as a preliminary step, to associate a corresponding value to each pollutant 1 detected in the delimited area "A".
Tale valore può essere definito in base ad un sistema di misura espresso in ppm (parti per milione) . Alternativamente, il valore può essere definito in base ad un sistema di riferimento relativo. In questo caso, ad esempio, il valore rilevato può essere definito in relazione ad un valore standard di riferimento. This value can be defined on the basis of a measurement system expressed in ppm (parts per million). Alternatively, the value can be defined on the basis of a relative reference system. In this case, for example, the measured value can be defined in relation to a standard reference value.
In un database 2, viene effettuato il salvataggio dei valori rilevati di ogni inquinante 1. In a database 2, the measured values of each pollutant 1 are saved.
Inoltre, al valore di ciascun inquinante 1 viene associata la relativa tipologia di inquinante espressa dal gruppo di sensori 3 di riferimento (VOC,monossido di carbonio,gas esausti). Furthermore, the relative type of pollutant expressed by the reference sensor group 3 (VOC, carbon monoxide, exhaust gas) is associated with the value of each pollutant 1.
Il gruppo di sensori 3 Ã ̈ caratterizzato da un sensore di VOC 9, un sensore di monossido di carbonio 10 e un sensore di gas esausti 11. Sensor group 3 features a VOC sensor 9, a carbon monoxide sensor 10 and an exhaust gas sensor 11.
Il gruppo di sensori 3 Ã ̈ montato su una scheda hardware con microcontrollore 4 dotato di interfaccia di rete tcp/ip 5. The sensor group 3 is mounted on a hardware board with microcontroller 4 equipped with a tcp / ip 5 network interface.
I valori di tensione di output dei relativi sensori 9,10,11 , viene quindi interpretato secondo dei valori di riferimento presenti nel database 2, che rappresentano la base di conoscenza per interpretare i dati 1 registrati. The output voltage values of the relative sensors 9,10,11 are then interpreted according to the reference values present in the database 2, which represent the knowledge base for interpreting the recorded data 1.
Per unità di elaborazione 6 si può intendere un comune calcolatore o un web server in cui sia contenuto il database 2. By processing unit 6 we can mean a common computer or a web server in which the database 2 is contained.
La comunicazione del dato 1 all'unità 6 avviene mediante protocollo di rete tcp/ip. The communication of data 1 to unit 6 takes place via the tcp / ip network protocol.
Vantaggiosamente, il dispositivo 6 può essere anche uno spazio web remoto. Advantageously, device 6 can also be a remote web space.
La scheda hardware con microcontrollore 4 monta anche un sensore fotoelettrico 7 in grado di determinare l'intensità luminosa incidente e quindi l'efficacia dell'azione fotocalitica . The hardware card with microcontroller 4 is also equipped with a photoelectric sensor 7 capable of determining the incident light intensity and therefore the effectiveness of the photocalytic action.
Alternativamente, la scheda hardware con microcontrollore 4 può essere interrogata mediante interfaccia di rete tcp/ip (wifi/ethernet) 5 per ottenere tramite interfaccia web html 8 un feedback tempo-reale in funzione di una logica standard di interpretazione tempo-reale del dato 1. Tale scheda hardware con microcontrollore 4 può quindi essere interrogata da dispositivi pc, des ktop,pa lmari ,smartphone ,tablet dotati di browser web e di connettività tcp/ip. Alternatively, the hardware card with microcontroller 4 can be interrogated via the tcp / ip network interface (wifi / ethernet) 5 to obtain real-time feedback via the html 8 web interface according to a standard logic of real-time interpretation of the data 1 This hardware card with microcontroller 4 can therefore be interrogated by pc, des ktop, pa lmari, smartphone, tablet devices equipped with web browser and tcp / ip connectivity.
Una volta che il valore dell'inquinante 1 da monitorare à ̈ individuato dal sensore di riferimento, il suo valore viene comunicato dalla scheda hardware con microcontrollore 4 al dispositivo 6 che ne salva il valore numerico, la tipologia, data e orario, radiazione rilevata dal sensore 7 nel database 2. Once the value of the pollutant 1 to be monitored is identified by the reference sensor, its value is communicated by the hardware card with microcontroller 4 to the device 6 which saves the numerical value, the type, date and time, radiation detected by the sensor 7 in database 2.
Interrogando direttamente la scheda hardware con microcontrollore 4 Ã ̈ possibile ottenere un feedback tempo reale del livello di inquinamento da materiali fotocalizzabili mediante nanotecnologia attiva grazie ai valori 1 rilevati dal gruppo di sensori 3. Inoltre, il microcontrollore 4 restituisce il grado di azione della fotocatalisi mediante il valore rilevato dal sensore 7. By directly interrogating the hardware board with microcontroller 4, it is possible to obtain a real-time feedback of the level of pollution from photocalizable materials by means of active nanotechnology thanks to the values 1 detected by the group of sensors 3. Furthermore, the microcontroller 4 returns the degree of action of the photocatalysis by means of the value detected by the sensor 7.
A titolo di esempio, la presenza di nanotecnologia attiva in un ambiente non à ̈ di per sé sufficiente a catalizzare degli inquinanti, in quanto per attivare l'effetto foto catalitico à ̈ necessaria la presenza di luce da fornire radiazione UV sufficiente all'attivazione della reazione foto catalitica stessa. Di conseguenza solo in presenza di un valore rilevato dal sensore 7 superiore ad una soglia di azione foto catalitica à ̈ possibile che la fotocatalisi sia in azione. By way of example, the presence of active nanotechnology in an environment is not in itself sufficient to catalyze pollutants, as to activate the photo-catalytic effect, the presence of light is required to provide sufficient UV radiation for activation. of the photo-catalytic reaction itself. Consequently, only in the presence of a value detected by the sensor 7 higher than a photo catalytic action threshold is it possible that the photocatalysis is in action.
L'unità di elaborazione 6, dunque, effettua una registrazione del dato inviato da 4 nel database 2. Tale dato à ̈ quindi consultabile per monitorare nel tempo l'evoluzione stessa dei valori 1 in funzione anche del valore del sensore 7. The processing unit 6, therefore, records the data sent by 4 in the database 2. This data can then be consulted to monitor the evolution of the values 1 over time as a function also of the value of the sensor 7.
Oltre a monitorare in tempo-reale i valori degli inquinanti à ̈ quindi possibile verificarne l'evoluzione temporale facendo attenzione anche al livello di radiazione luminosa incidente. In addition to monitoring the pollutant values in real time, it is therefore possible to verify their temporal evolution by also paying attention to the level of incident light radiation.
Il sistema 6 restituisce relativamente ad un arco temporale stabilito dall'utente il valore del rischio da inquinanti fotocatalizzabili con l'algoritmo richiamato in seguito. The system 6 returns the value of the risk from photocatalizable pollutants with the algorithm referred to below, relative to a period of time established by the user.
Considerato "Ni" il primo numero che descrive il valore di VOC inquinante, †N2" il secondo numero che descrive il valore di monossido di carbonio inquinante, "N3" il terzo numero che descrive il valore di gas esausti inquinanti,ad un determinato istante "tO" di rilevazione il valore di inquinamento "ICftCJ" à ̈ un numero ottenuto dopo una normalizzazione dei dati, che includono valori di importanza dei singoli componenti, cioà ̈: Considered "Ni" the first number describing the polluting VOC value, â € N2 "the second number describing the polluting carbon monoxide value," N3 "the third number describing the polluting exhaust gas value, to a given detection instant "tO" the pollution value "ICftCJ" is a number obtained after a normalization of the data, which include values of importance of the individual components, that is:
VI = 1 - (Nl/Nlmax); V2 = 1 - (N2/N2max); VI = 1 - (Nl / Nlmax); V2 = 1 - (N2 / N2max);
V3 = 1 - (N3/N3max) con Nlmax,N2max,N3max stabiliti in base a conoscenze teoriche. Definiti γΠ, γ2, γ3 (pesi di importanza dei componenti singoli, 0<γΠ̄≤1) il valore di inquinamento complessivo "IC" à ̈ stabilito dalla formula : V3 = 1 - (N3 / N3max) with Nlmax, N2max, N3max established on the basis of theoretical knowledge. Defined γÎ, γ2, γ3 (weights of importance of the single components, 0 <γΠ̄â ‰ ¤1) the total pollution value "IC" is established by the formula:
((yl)· X VI - (γ2)~ X V2 - (y3)~ X V3)) ((yl) X VI - (γ2) ~ X V2 - (y3) ~ X V3))
IC = IC =
(Yl)<:>-(y2)<;>-(y3)<:>(Yl) <:> - (y2) <;> - (y3) <:>
Tale valore in relazione con un valore numerico soglia di riferimento ne determina il rischio da inquinamento indoor nano catalizzabile. In presenza di suddetto rischio e in presenza di una quantità di luce sufficiente ad attivare tale reazione foto catalitica la catalisi di tali inquinanti à ̈ quindi possibile . This value in relation to a numerical reference threshold value determines the risk of catalysable nano indoor pollution. In the presence of this risk and in the presence of a sufficient quantity of light to activate this photo-catalytic reaction, the catalysis of these pollutants is therefore possible.
Oltre a restituire un feedback sul livello di inquinamento il sistema à ̈ in grado di suggerire una applicazione di nanotecnologia specifica in funzione delle dimensioni dell'area "A" monitorata, in termini di metri quadri da interessare con il prodotto nanotecnologico, specifiche relative al livello di luminosità dell'ambiente e specifiche al composto nano tecnologico da utilizzare (dimensioni delle nano particelle, formulazione chimica del composto) e relativa quantità di aria pulita prevista dopo l'applicazione . In addition to providing feedback on the level of pollution, the system is able to suggest a specific application of nanotechnology according to the size of the monitored area "A", in terms of square meters to be involved with the nanotechnological product, specifications relating to the level brightness of the environment and specific to the nano technological compound to be used (size of the nano particles, chemical formulation of the compound) and relative amount of clean air expected after application.
