DISPOSITIVO PER LA RIDUZIONE DELLE EMISSIONI NOCIVE IN VEICOLI DEVICE FOR THE REDUCTION OF HARMFUL EMISSIONS IN VEHICLES
STRADALI ROADS
Campo tecnico Technical field
La presente invenzione ha per oggetto un dispositivo per la riduzione delle emissioni nocive in veicoli stradali. The present invention relates to a device for reducing harmful emissions in road vehicles.
Arte nota Known art
È noto che l’inquinamento dovuto all’uso di veicoli stradali motorizzati, quali automobili e simili, è un problema crescente al livello mondiale. I modelli recenti di automobili sono provvisti di dispositivi anti inquinamento atti a diminuire le emissioni di gas inquinanti, generalmente integrati al sistema di scappamento dei gas emessi dal motore. It is known that pollution due to the use of motorized road vehicles, such as cars and the like, is a growing problem worldwide. Recent car models are equipped with anti-pollution devices designed to reduce polluting gas emissions, generally integrated into the exhaust system of the gases emitted by the engine.
Ad esempio il brevetto FR 2863653 presenta un dispositivo di filtraggio comprendente una cassetta provvista di una porzione a monte, atta ad essere collegata ad almeno un tubo di alimentazione di gas di scarico, e di una porzione a valle atta ad essere collegata ad almeno un tubo di evacuazione di gas di scarico. For example, the patent FR 2863653 presents a filtering device comprising a cassette provided with an upstream portion, able to be connected to at least one exhaust gas supply pipe, and a downstream portion able to be connected to at least one pipe for evacuation of exhaust gases.
Tali dispositivi, integrati nella linea di scappamento dei veicoli nuovi, non sono adattabili a veicoli vecchi che non ne sono provvisti. Inoltre, il cambio del filtro usato richiede un’operazione di smontaggio del dispositivo che risulta faticosa e richiede strumenti particolari. These devices, integrated in the exhaust line of new vehicles, are not adaptable to old vehicles that are not equipped with them. In addition, changing the used filter requires disassembly of the device which is tiring and requires special tools.
Per risolvere questo problema sono stati escogitati dei dispositivi più semplici. Ad esempio la domanda di brevetto francese FR 2870885 illustra un dispositivo per filtrare micro particelle dai gas di scarico dei veicoli motorizzati, costituito di un filtro di maglia molto sottile, fissato all’estremità di un tubo di scarico tramite una fascetta di serraggio. To solve this problem simpler devices have been devised. For example, the French patent application FR 2870885 illustrates a device for filtering micro particles from the exhaust gases of motorized vehicles, consisting of a very thin mesh filter, fixed to the end of an exhaust pipe by means of a clamp.
Tale soluzione nota non soddisfa pienamente le esigenze degli utilizzatori, in quanto propone un filtraggio meccanico dei gas di scarico, con una efficacia ridotta rispetto ai sistemi aventi un filtraggio sia meccanico che chimico. This known solution does not fully satisfy the needs of users, since it proposes a mechanical filtering of the exhaust gases, with a reduced efficiency compared to systems having both mechanical and chemical filtering.

È da notare che il dispositivo 1 secondo la presente invenzione consente di cambiare agevolmente l’elemento filtrante 9. Dopo aver aperto il coperchio 6 è possibile estrarre la cuffia 9 senza smontare l’involucro 2. È possibile anche estrarre il corpo di supporto 10 assieme all’elemento filtrante 9, per il fatto che l’involucro 2 e il corpo di supporto 10 non sono connessi l’uno all’altro. It should be noted that the device 1 according to the present invention makes it possible to easily change the filter element 9. After opening the cover 6 it is possible to extract the cap 9 without disassembling the casing 2. It is also possible to extract the support body 10 together to the filter element 9, due to the fact that the casing 2 and the support body 10 are not connected to each other.
Il dispositivo in oggetto raggiunge lo scopo di ridurre in modo efficace le emissioni nocive in veicoli stradali, operando un filtraggio sia meccanico, mediante la rete compresa nel corpo di supporto 10 e i fori 3 dell’involucro 2, che chimico, tramite l’elemento filtrante 9. The device in question achieves the purpose of effectively reducing harmful emissions in road vehicles, by operating both mechanical filtering, by means of the mesh included in the support body 10 and the holes 3 of the casing 2, and chemical, by means of the filtering element. 9.
Tale risultato è ottenuto in particolare grazie all'idea inventiva di prevedere un corpo di supporto 10 comprendente una rete metallica zincata, avvolto nella cuffia 9 a carboni attivi e inserito nell’involucro 2 provvisto di fori 3. È da notare che la presenza del corpo di supporto 9 consente di mantenere la forma di cuffia dell’elemento filtrante 9 in modo da avvolgere tutto lo spazio interno all’involucro 2 e intercettare tutti i gas in uscita dal tubo di scappamento. This result is achieved in particular thanks to the inventive idea of providing a support body 10 comprising a galvanized metal mesh, wrapped in the activated carbon cap 9 and inserted in the casing 2 provided with holes 3. It should be noted that the presence of the body support 9 allows to maintain the hood shape of the filter element 9 so as to envelop all the space inside the casing 2 and to intercept all the gases leaving the exhaust pipe.
Una prerogativa del dispositivo in oggetto è costituita dal fatto che risulta facile da montare su qualsiasi tipo di veicolo stradale, perché viene semplicemente montato all’estremità del tubo di scappamento. A prerogative of the device in question is the fact that it is easy to mount on any type of road vehicle, because it is simply mounted at the end of the exhaust pipe.
Un altro vantaggio del dispositivo in oggetto è quello di consentire di cambiare il filtro facilmente e senza utensili particolari, grazie al fatto che il dispositivo 1 è realizzato e montato all’estremità di un tubo di scarico senza necessitare nessuna connessione tra il corpo di supporto 10 e l’involucro 2. Another advantage of the device in question is that of allowing the filter to be changed easily and without special tools, thanks to the fact that the device 1 is made and mounted at the end of an exhaust pipe without requiring any connection between the support body 10. and casing 2.
