DISPOSITIVO PER L’ASPIRAZIONE E FILTRAZIONE DI POLVERI DEVICE FOR DUST SUCTION AND FILTRATION
SOTTILI NELL’ARIA THIN IN THE AIR
DESCRIZIONE DESCRIPTION
Il presente brevetto à ̈ attinente ai dispositivi per la filtrazione e depurazione dell’aria ed in particolare concerne un nuovo dispositivo passivo per l’aspirazione e filtrazione delle polveri sottili nell’aria, atto ad essere installato su veicoli mobili quali autobus, pullman, tram o altri mezzi a circolazione prevalentemente cittadina o comunque in ambienti con elevate concentrazioni di dette polveri in atmosfera. This patent relates to devices for air filtration and purification and in particular concerns a new passive device for the aspiration and filtration of fine dust in the air, suitable for installation on mobile vehicles such as buses, buses, trams or other vehicles with mainly urban circulation or in any case in environments with high concentrations of said dust in the atmosphere.
E’ noto, e particolarmente sentito, il problema delle elevate concentrazioni in atmosfera di polveri sottili o particolato, cioà ̈ di particelle solide o liquide sospese nell'aria, aventi diametro caratteristico uguale o inferiore a 10 µm e comunemente definite PM10. The problem of high concentrations in the atmosphere of fine powders or particulates, that is solid or liquid particles suspended in the air, having a characteristic diameter equal to or less than 10 µm and commonly defined as PM10 is known and particularly felt.
Le origini delle emissioni di PM10 sono di tipo naturale, come l’erosione del suolo, la diffusione di pollini e di spore, o di tipo antropico. The origins of PM10 emissions are natural, such as soil erosion, the spread of pollen and spores, or anthropogenic.
In particolare, nelle aree urbane, tali sostanze sono principalmente generate dalla combustione dei motori a scoppio, dagli impianti di riscaldamento e dalle emissioni industriali, dal traffico veicolare. In particular, in urban areas, these substances are mainly generated by the combustion of internal combustion engines, heating systems and industrial emissions, from vehicular traffic.
Il PM10 à ̈ estremamente pericoloso per l’uomo, causa irritazioni e infiammazioni, ma anche patologie più gravi e croniche. Le polveri fini vengono infatti facilmente inalate e inoltre contengono microinquinanti molto nocivi, come metalli pesanti e idrocarburi policiclici aromatici. PM10 is extremely dangerous for humans, it causes irritation and inflammation, but also more serious and chronic pathologies. In fact, fine powders are easily inhaled and also contain very harmful micropollutants, such as heavy metals and polycyclic aromatic hydrocarbons.
Il PM10 comporta anche alterazioni delle proprietà fisiche dell’atmosfera, come la visibilità , la riflessione e la rifrazione della luce, e provoca l’annerimento delle pareti esterne di edifici e monumenti. PM10 also implies alterations in the physical properties of the atmosphere, such as visibility, reflection and refraction of light, and causes blackening of the external walls of buildings and monuments.
Sono noti vari metodi e dispositivi di trattamento dell’aria, volti all’abbattimento degli agenti inquinanti e delle polveri sottili. Various methods and devices for air treatment are known, aimed at reducing pollutants and fine dust.
Sono noti metodi e dispositivi atti a depurare e depolverizzare l’aria in ambienti chiusi o posti immediatamente a valle della fonte di inquinanti, atti a limitarne la diffusione. Methods and devices are known which are suitable for purifying and de-dusting the air in closed environments or places immediately downstream of the source of pollutants, suitable for limiting its diffusion.
Per abbattere efficacemente l’inquinamento atmosferico cittadino derivante da polveri sottili prodotte dal traffico veicolare, à ̈ anche noto l’utilizzo di dispositivi fissi di filtrazione e depurazione dell’aria collocati in ambienti urbani nelle immediate vicinanze delle strade e dei nodi viari maggiormente trafficati, allo scopo di limitare la diffusione delle polveri sottili nello spazio circostante. To effectively reduce city air pollution deriving from fine dust produced by vehicular traffic, the use of fixed air filtration and purification devices located in urban environments in the immediate vicinity of roads and traffic junctions is also known. more heavily trafficked, in order to limit the spread of fine dust in the surrounding space.
Tali dispositivi, che contribuiscono a migliorare la qualità dell’aria nell’ambiente urbano, presentano tuttavia alcuni inconvenienti. These devices, which help to improve the quality of the air in the urban environment, however, have some drawbacks.
Innanzitutto essi hanno un ingombro e un impatto visivo che li rendono inadatti ad alcuni particolari contesti urbani, ad esempio quelli storici. First of all, they have a size and a visual impact that make them unsuitable for some particular urban contexts, for example historical ones.
Detti dispositivi comportano inoltre consumi e costi energetici elevati e comunque necessitano di essere alimentati elettricamente realizzando impianti elettrici ad hoc. Said devices also involve high energy consumption and costs and in any case need to be electrically powered by creating ad hoc electrical systems.
Oltre a ciò, i dispositivi In addition to that, the devices
noti sono collocati in una postazione fissa, interessando quindi lo spazio circostante entro un raggio d’azione limitato. known are placed in a fixed position, thus affecting the surrounding space within a limited range of action.
Oggetto del presente brevetto à ̈ un nuovo tipo di dispositivo passivo per l’aspirazione e filtrazione delle polveri sottili nell’aria, dalle PM10 fino alle nanopolveri, atto ad essere installato su veicoli mobili quali autobus, pullman, tram o altri mezzi a circolazione prevalentemente cittadina o urbana o comunque in ambienti con elevate concentrazioni di dette polveri in atmosfera. The subject of this patent is a new type of passive device for the aspiration and filtration of fine dust in the air, from PM10 to nano-dust, suitable for installation on mobile vehicles such as buses, coaches, trams or other means of transport. mainly urban or urban circulation or in any case in environments with high concentrations of said dust in the atmosphere.
Compito principale del presente trovato à ̈ quello di aspirare e filtrare l’aria, abbattendone il carico inquinante ad esempio in termini di contenuto di polveri sottili, particolarmente in ambito urbano o cittadino, e dove l’aspirazione dell’aria avviene in modo passivo ossia sfruttando la velocità di un veicolo, quale un autobus, un pullman o un tram sul quale il dispositivo à ̈ installato, eliminando totalmente i costi energetici dovuti all’aspirazione. The main task of the present invention is that of sucking and filtering the air, reducing its polluting load, for example in terms of fine dust content, particularly in an urban or city environment, and where the air is sucked in passive mode, that is by exploiting the speed of a vehicle, such as a bus, a coach or a tram on which the device is installed, totally eliminating the energy costs due to suction.
Altro scopo del presente trovato à ̈ quello di essere mobile, interessando quindi una superficie urbana più vasta rispetto a quella interessata da un dispositivo fisso. Another object of the present invention is to be mobile, thus involving a larger urban surface than that affected by a fixed device.
Altro scopo del presente trovato à ̈ interessare una superficie urbana più vicina e prossima alla zona di maggiore produzione delle polveri sottili, limitandone quindi la diffusione nell’ambiente circostante. Another object of the present invention is to involve an urban surface that is closer and closer to the area of greatest production of fine dust, thus limiting its diffusion in the surrounding environment.
Altro vantaggio del presente trovato à ̈ poter essere installato sia su mezzi di trasporto esistenti, sia integrato in mezzi di trasporto nuovi. Another advantage of the present invention is that it can be installed both on existing means of transport and integrated in new means of transport.
Altro vantaggio à ̈ quello di contenere i consumi energetici, poiché viene sfruttata la velocità di transito del veicolo, senza richiedere quindi l’installazione di mezzi di aspirazione, e viene usata l’energia elettrica generata dall’impianto elettrico del mezzo stesso, in quanto il dispositivo à ̈ alimentato a bassa tensione e assorbe una potenza molto contenuta. Another advantage is to contain energy consumption, since the vehicle transit speed is exploited, without requiring the installation of suction means, and the electricity generated by the vehicle's electrical system is used. itself, as the device is powered at low voltage and absorbs very little power.
Altro vantaggio del presente trovato à ̈ ottimizzare il rendimento di abbattimento delle poveri sottili fino ad una velocità di 70 km/h del mezzo sul quale il dispositivo à ̈ installato, grazie all’impiego di dispositivi di controllo dei valori della portata dell’aria in ingresso al dispositivo, che devono essere mantenuti entro i valori ottimali di progetto, dove à ̈ massimo il rendimento. Another advantage of the present invention is to optimize the efficiency of abatement of the thin materials up to a speed of 70 km / h of the vehicle on which the device is installed, thanks to the use of devices for controlling the values of the flow rate of the air entering the device, which must be kept within the optimal design values, where efficiency is maximum.
Questi ed altri scopi, diretti e complementari, sono raggiunti dal nuovo dispositivo passivo per l’aspirazione e filtrazione delle polveri sottili nell’aria, atto ad essere installato su veicoli mobili quali autobus, pullman, tram o altri mezzi a circolazione prevalentemente cittadina o urbana. These and other direct and complementary purposes are achieved by the new passive device for the aspiration and filtration of fine dust in the air, designed to be installed on mobile vehicles such as buses, coaches, trams or other mainly urban circulation vehicles. or urban.
Il nuovo dispositivo à ̈ atto ad essere installato o integrato in un veicolo e comprende uno o più mezzi di filtrazione dell’aria, almeno una bocca di aspirazione dell’aria, posta sul fronte anteriore rispetto alla direzione di avanzamento normale del veicolo, e almeno una bocca di espulsione del flusso d’aria filtrato. The new device is designed to be installed or integrated in a vehicle and includes one or more air filtration means, at least one air intake port, placed on the front face with respect to the normal direction of travel of the vehicle, and at least one outlet for the expulsion of the filtered air flow.
Detto nuovo dispositivo à ̈ dunque atto ad essere applicato preferibilmente sul tetto di mezzi di locomozione cittadini quali autobus, pullman, tram, mezzi di servizio urbano o simili, ossia mezzi che seguono percorsi in ambito urbano e cittadino, o comunque nelle aree maggiormente interessate dall’inquinamento da polveri sottili dovute al traffico veicolare. Said new device is therefore suitable for being preferably applied on the roof of city means of locomotion such as buses, coaches, trams, urban service vehicles or the like, i.e. vehicles that follow routes in urban and city settings, or in any case in the areas most affected by the € ™ pollution by fine dust due to vehicular traffic.
Detti dispositivi, installati su detti mezzi di locomozione che percorrono le strade cittadine, aspirano aria carica di polveri sottili attraverso detta bocca di aspirazione. Said devices, installed on said means of locomotion which travel along the city streets, suck in air charged with fine dust through said suction mouth.
Il flusso d’aria aspirata viene convogliata attraverso detti mezzi di filtrazione e viene poi espulsa in atmosfera attraverso detta bocca di espulsione, posta preferibilmente nel fronte posteriore del dispositivo, rispetto alla direzione di avanzamento normale del veicolo. The flow of sucked air is conveyed through said filtration means and is then expelled into the atmosphere through said expulsion mouth, preferably located in the rear face of the device, with respect to the normal forward direction of the vehicle.
Nel dettaglio, si prevede che detti mezzi di filtrazione comprendano un primo filtro in tessuto filtrante, ad esempio preferibilmente in classe F8, in grado di trattenere polveri fino a 4 Î1⁄4g. In detail, it is envisaged that said filtration means comprise a first filter in filtering fabric, for example preferably in class F8, capable of retaining dust up to 4 µ1⁄4g.
Detto tessuto filtrante à ̈ preferibilmente avvolto in almeno due bobine, di cui una di riavvolgimento motorizzata, atta a riavvolgere il tessuto quando la porzione investita dal flusso d’aria da filtrare à ̈ esaurita, e una di caricamento, preferibilmente a rotazione frenata o folle, su cui à ̈ avvolto il tessuto filtrante da svolgere. Said filtering fabric is preferably wound in at least two reels, one of which for motorized rewinding, suitable for rewinding the fabric when the portion hit by the air flow to be filtered is exhausted, and one for loading, preferably with braked rotation or neutral, on which the filter fabric to be unwound is wound.
Almeno un lettore ottico di opacità rileva il grado di intasamento del tessuto, controllando quindi un modo automatico la traslazione e il riavvolgimento del tessuto stesso quando necessario. At least one optical opacity reader detects the degree of clogging of the fabric, thus automatically controlling the translation and rewinding of the fabric itself when necessary.
Si prevede che in posizione retrostante a detto tessuto sia collocato almeno un supporto forato rigido o semirigido, atto a mantenere detto tessuto in tensione, per garantire una filtrazione ottimale. At least one rigid or semi-rigid perforated support is provided in a position behind said fabric, suitable for keeping said fabric under tension, to ensure optimal filtration.
Detti mezzi di filtrazione comprendono inoltre, a valle di detto tessuto filtrante, uno o più elettrofiltri o celle elettrostatiche alimentate a bassa tensione, in grado di garantire la filtrazione di particelle di dimensioni caratteristiche fino a 60 nm. Said filtration means furthermore comprise, downstream of said filtering fabric, one or more low voltage electrostatic filters or electrostatic cells, capable of guaranteeing the filtration of particles with characteristic dimensions up to 60 nm.
Nella soluzione preferita, il nuovo dispositivo comprende un telaio di contenimento di detti componenti, conformata in modo tale da poter essere installato sul tetto di detti veicoli mobili. In the preferred solution, the new device comprises a frame for containing said components, shaped in such a way that it can be installed on the roof of said mobile vehicles.
Detto telaio di contenimento à ̈ preferibilmente una carcassa in vetroresina o altro materiale idoneo di peso contenuto, atta a proteggere i componenti interni e a favorire il deflusso dell’aria. Said containment frame is preferably a carcass in fiberglass or other suitable material of low weight, suitable for protecting the internal components and favoring the flow of air.
Si può anche prevedere che la superficie esterna di detta carcassa possa anche convenientemente essere utilizzata per l’applicazione ad esempio di pannelli a scopo anche pubblicitario o di sensibilizzazione. It can also be envisaged that the external surface of said casing can also be conveniently used for the application, for example, of panels for advertising or awareness raising purposes.
Detti pannelli hanno anche la funzione di coprire, riparare o nascondere il dispositivo installato sul tetto del veicolo. These panels also have the function of covering, repairing or hiding the device installed on the vehicle roof.
In alternativa, detto dispositivo à ̈ atto all’installazione integrata in detto veicolo mobile, e dove detta bocca di aspirazione à ̈ collocabile conveniente sulla parte anteriore del veicolo, rivolta nella direzione di avanzamento del veicolo stesso, ad esempio lateralmente e/o sul tetto del veicolo e/o sulla parte inferiore del veicolo. Alternatively, said device is suitable for integrated installation in said mobile vehicle, and where said suction mouth can be conveniently placed on the front part of the vehicle, facing the direction of advancement of the vehicle itself, for example laterally and / or on the roof of the vehicle and / or on the underside of the vehicle.
Il nuovo dispositivo comprende inoltre almeno un sistema di controllo della portata dell’aria da filtrare in ingresso a detti filtri, allo scopo di ottimizzarne il rendimento. The new device also comprises at least one system for controlling the flow rate of the air to be filtered at the inlet of said filters, in order to optimize their efficiency.
Infatti, il rendimento di abbattimento delle polveri sottili da parte dei mezzi di filtrazione à ̈ funzione della portata di aria in ingresso, dove all’aumentare della portata, dovuta all’aumentare della velocità dell’aria in ingresso al dispositivo, il rendimento diminuisce, secondo il diagramma di figura 1. In particolare, detto sistema di controllo ha la funzione di mantenere il rendimento di abbattimento dei filtri a valori elevati, superiori a 93% fino a velocità dell’aria in ingresso dell’ordine di 70 kilometri orari, che equivale alla velocità del veicolo. In fact, the efficiency of the reduction of fine dust by the filtration media is a function of the incoming air flow rate, where, as the flow rate increases, due to the increase in the speed of the air entering the device, the efficiency decreases, according to the diagram in figure 1. In particular, said control system has the function of maintaining the filter abatement efficiency at high values, higher than 93% up to an incoming air speed of the order of 70 kilometers per hour, which is equivalent to the speed of the vehicle.
Superata questa velocità il rendimento della filtrazione diminuisce. Once this speed is exceeded, the filtration efficiency decreases.
Nella soluzione preferita, il nuovo dispositivo comprende un primo sistema di controllo “a labirinto†della portata di aria da filtrare, collocato a monte dei mezzi di filtrazione, a valle e in prossimità di detta bocca di aspirazione. In the preferred solution, the new device comprises a first â € œ labyrinthâ € control system for the air flow to be filtered, located upstream of the filtration means, downstream and close to said suction mouth.
Detto primo sistema di controllo “a labirinto†comprende uno o più setti posti trasversalmente alla direzione del flusso di aria in ingresso, che viene convogliata lungo un percorso a serpentina. Said first "labyrinth" control system includes one or more baffles placed transversely to the direction of the incoming air flow, which is conveyed along a serpentine path.
Almeno uno di detti setti à ̈ flessibile verso uno dei setti vicini o verso una parete, e dove la flessione di detto setto à ̈ provocata dalla spinta dell’aria in ingresso, quando la sua velocità supera un valore limite definito, ad esempio di 20 Km/h. At least one of said septa is flexible towards one of the neighboring septa or towards a wall, and where the bending of said septum is caused by the thrust of the incoming air, when its speed exceeds a defined limit value, for example of 20 Km / h.
La flessione di detto setto verso il setto vicino o verso detta parete riduce la sezione di passaggio dell’aria in ingresso, controllando quindi la portata, che deve essere mantenuta costantemente sui valori ottimali di progetto. The bending of said septum towards the neighboring septum or towards said wall reduces the passage section of the incoming air, thus controlling the flow rate, which must be kept constantly on the optimal design values.
Nella soluzione preferita, il nuovo dispositivo comprende anche almeno un ulteriore sistema di controllo o compensatore o ottimizzatore della velocità dell’aria in ingresso al dispositivo, per controllare la portata d’aria da trattare da detti filtri di abbattimento delle polveri sottili. In the preferred solution, the new device also comprises at least one further control system or compensator or optimizer of the speed of the air entering the device, to control the flow rate of air to be treated by said filters for reducing fine dust.
Detto compensatore o ottimizzatore, realizzato in fibre reticolate di acciaio, à ̈ installato a monte delle celle elettrostatiche di filtrazione e hanno la funzione di distribuire l’aria da trattare in modo che tutte dette celle trattino un’uguale portata di aria. Said compensator or optimizer, made of cross-linked steel fibers, is installed upstream of the electrostatic filtration cells and has the function of distributing the air to be treated so that all said cells treat an equal air flow.
Si prevede che in corrispondenza di detta bocca di aspirazione e di detta bocca di espulsione siano installate serrande di apertura/chiusura, comandate ciascuna da almeno un motore a bassa tensione. It is envisaged that opening / closing dampers, each controlled by at least one low voltage motor, are installed in correspondence with said suction mouth and said expulsion mouth.
Si prevede che il nuovo dispositivo sia alimentato elettricamente dall’impianto elettrico del veicolo. The new device is expected to be powered electrically by the vehicle's electrical system.
Nella soluzione preferita, si prevede l’impiego di elettrofiltri che assorbano una potenza molto bassa, ad esempio di 30W ciascuno, necessitando quindi di un’alimentazione in bassa tensione, a 24V, che viene fornita dal circuito elettrico del veicolo. In the preferred solution, the use of electrofilters is envisaged which absorb a very low power, for example of 30W each, thus requiring a low voltage power supply, 24V, which is supplied by the vehicle electrical circuit.
L’assorbimento di potenza dell’intero dispositivo à ̈ minimo, stimabile intorno ai 100W, comportando costi energetici praticamente nulli. The power consumption of the entire device is minimal, estimated at around 100W, resulting in practically zero energy costs.
Inoltre, su tram o altri veicoli alimentati elettricamente o a motore elettrico, si può anche prevede di installare più di un dispositivo, anche di potenze maggiori, trattando quantità d’aria atmosferica ancora maggiori e minimizzando ulteriormente l’impatto ambientale Furthermore, on trams or other electrically powered or electric motor vehicles, it is also possible to install more than one device, even with higher powers, treating even greater quantities of atmospheric air and further minimizing the environmental impact.
Si prevede che il dispositivo possa essere acceso mediante apposito interruttore o comando oppure direttamente tramite accensione del veicolo. Si può infatti prevedere che detto nuovo dispositivo possa essere ad esempio collegato al quadro di accensione del veicolo, cosicché quando l’operatore gira la chiave di accensione nel quadro, provoca la contemporanea attivazione del dispositivo. It is envisaged that the device can be switched on by means of a suitable switch or command or directly by switching on the vehicle. In fact, it can be envisaged that said new device can be connected, for example, to the ignition panel of the vehicle, so that when the operator turns the ignition key in the panel, it causes the device to be activated at the same time.
Si può prevedere che il nuovo dispositivo comprenda anche almeno un sensore di pioggia che, in caso di precipitazioni, trasmette in segnale a detto motore di dette serrande delle bocche di aspirazione e di espulsione, in modo da provocare la chiusura della bocca, evitando infiltrazioni di acqua nei sistemi filtranti, e lo spegnimento del dispositivo o dei soli elettrofiltri. Nel dettaglio, in caso di pioggia, detto sensore di pioggia comanda, nell’ordine, lo spegnimento di detti elettrofiltri, la chiusura di detta serranda della bocca di aspirazione e la chiusura di detta serranda della bocca di espulsione. It can be envisaged that the new device also includes at least one rain sensor which, in the event of precipitation, transmits a signal to said motor of said shutters of the suction and expulsion openings, so as to cause the closure of the mouth, avoiding infiltration of water in the filter systems, and the switching off of the device or of the electrofilters only. In detail, in case of rain, said rain sensor commands, in order, the shutdown of said electrofilters, the closure of said shutter of the suction mouth and the closure of said shutter of the expulsion mouth.
Quando detto sensore rileva che le precipitazioni atmosferiche sono cessate, autorizza la riapertura dette serrande e riattiva detti elettrofiltri. When said sensor detects that the atmospheric precipitations have ceased, it authorizes the reopening of said shutters and reactivates said electrofilters.
Ipotizzando, per ciascun dispositivo, una portata d’aria filtrata media pari a circa 11.500 m<3>/h e considerando un veicolo come un autobus di linea che, durante una giornata, à ̈ in movimento per 19 ore, la quantità d’aria filtrata risulta pari a circa 218.500 m<3>. Assuming, for each device, an average filtered air flow rate of approximately 11,500 m <3> / h and considering a vehicle as a bus which, during a day, is in motion for 19 hours, the quantity of ™ filtered air is equal to approximately 218,500 m <3>.
Se ipotizziamo di installare il sistema su 50 autobus, la quantità di aria filtrata in un giorno sarà di circa 10.925.000 m<3>, e, quindi, di circa 327.000.000 m<3>in un mese di 30 giorni. If we assume to install the system on 50 buses, the amount of filtered air in a day will be about 10,925,000 m <3>, and therefore about 327,000,000 m <3> in a month of 30 days.
Il nuovo dispositivo può anche essere installato su veicoli più piccoli, ad esempio minibus, trattando portate d’aria inferiori, ad esempio di circa 6000 m<3>/h. The new device can also be installed on smaller vehicles, such as minibuses, treating lower airflows, for example about 6000 m <3> / h.
Un dispositivo di minori dimensioni, se invece installato su autoveicoli di servizio ad esempio sulle barre montate sul tettuccio del veicolo, può trattare portate d’aria fino a 4000 m<3>/h. A smaller device, if instead installed on service vehicles, for example on the bars mounted on the roof of the vehicle, can handle air flows up to 4000 m <3> / h.
Pertanto, il nuovo dispositivo provvede al trattamento di enormi portate di aria a costi assolutamente minimizzati. Therefore, the new device provides for the treatment of enormous air flow rates at absolutely minimized costs.
