Descrizione dell?invenzione avente per titolo ?Sistema di abbattimento delle emissioni di gas serra prodotte dagli allevamenti bovini? Description of the invention entitled ?System for reducing greenhouse gas emissions produced by cattle breeding?
Campo di applicazione Field of application
La presente invenzione trova applicazione nel settore tecnico zootecnico ed ha per oggetto un sistema pensato per ridurre l?impatto ambientale degli allevamenti bovini attraverso la trasformazione dei gas serra emessi dagli stessi in energia elettrica e termica. The present invention finds application in the technical livestock sector and has as its object a system designed to reduce the environmental impact of cattle breeding through the transformation of the greenhouse gases emitted by them into electrical and thermal energy.
Stato della tecnica State of the art
Il sistema di abbattimento delle emissioni di gas serra prodotte dagli allevamenti bovini si propone come un'invenzione in linea con l?interesse sociale e mediatico sulla lotta all?inquinamento ma che, allo stato attuale, non riscontra tecnologie mature simili nel mercato. The system for reducing greenhouse gas emissions produced by cattle farming is proposed as an invention in line with the social and media interest in the fight against pollution but which, at present, does not find similar mature technologies on the market.
Uno dei tentativi effettuati nel corso degli anni per mitigare il problema del potenziale inquinante dei bovini pu? essere considerato quello dell'Universit? di Buenos Aires che, nel 2013, ha attuato un sistema artigianale per la cattura di questi gas con un sistema di cannule comunicanti direttamente con lo stomaco del bovino dal quale il gas veniva intercettato e inviato ad un cuscinetto di plastica posto sul dorso dell?animale. In Galles, invece, sono stati esaminati gli effetti di estratti a base d'aglio che potessero ridurre la produzione di metano. Entrambi tentativi che, pare, sembrano essersi arenati. One of the attempts made over the years to mitigate the problem of the polluting potential of cattle can? be considered that of the University? of Buenos Aires which, in 2013, implemented an artisanal system for the capture of these gases with a system of cannulae communicating directly with the stomach of the cattle from which the gas was intercepted and sent to a plastic pad placed on the back of the animal . In Wales, however, the effects of garlic-based extracts that could reduce methane production were examined. Both attempts which, it seems, seem to have run aground.
La gravit? dell?inquinamento derivante dagli allevamenti bovini la rappresentano i numeri: se i bovini rappresentassero una nazione, essa sarebbe la terza al mondo per emissioni di gas serra. Il settore primario ? il secondo settore pi? inquinante (24%) dopo quello dell?elettricit? e del riscaldamento (25%); mentre l?agricoltura ha trovato possibili soluzioni per mitigare tali emissioni inquinanti, lo stato di avanzamento innovativo della zootecnia sembra fermo. Gravity? the numbers represent the pollution deriving from cattle farming: if cattle represented a nation, it would be the third in the world for greenhouse gas emissions. The primary sector? the second sector more? polluting (24%) after that of electricity? and heating (25%); while agriculture has found possible solutions to mitigate these polluting emissions, the innovative state of progress of animal husbandry seems to be at a standstill.
Le emissioni di gas serra del reparto zootecnico riguardano la produzione di anidride carbonica (CO2), quella di metano (CH4), con un potenziale di gas serra 25 volte quello dell?anidride carbonica, e la produzione di protossido di azoto (N2O), il cui potenziale ? 298 volte quello dell?anidride carbonica. Greenhouse gas emissions from the livestock department concern the production of carbon dioxide (CO2), that of methane (CH4), with a greenhouse gas potential 25 times that of carbon dioxide, and the production of nitrous oxide (N2O), whose potential? 298 times that of carbon dioxide.
Mentre il protossido di azoto deriva in larghissima parte dalla decomposizione del letame non gestito, anidride carbonica e metano derivano dal processo digestivo dei bovini. Nel corso degli anni si ? quindi ovviato all?inefficienza della gestione del letame impiegandolo come substrato per la produzione di biogas in digestori; per quanto riguarda invece l?abbattimento degli altri due gas serra non si ? ancora trovata alcuna soluzione, nonostante la decomposizione del letame sia responsabile solo del 16% dell?inquinamento derivante dal settore primario, mentre il processo digestivo, con l?emissione dei gas serra che causa, ne ? la causa per il 40% dell?inquinamento. While nitrous oxide comes largely from the decomposition of unmanaged manure, carbon dioxide and methane come from the digestive process of cattle. Over the years yes? therefore the inefficiency of manure management was overcome by using it as a substrate for the production of biogas in digesters; However, as far as the abatement of the other two greenhouse gases is concerned, this is not the case. no solution has yet been found, despite the fact that the decomposition of manure is responsible for only 16% of the pollution deriving from the primary sector, while the digestive process, with the emission of greenhouse gases it causes, is responsible for it. the cause of 40% of pollution.
Presentazione dell?invenzione Presentation of the invention
Scopo della presente invenzione ? quello di ridurre l?impatto ambientale degli allevamenti bovini e rendere autonomo a livello energetico l?intero stabilimento dell?allevamento partendo dal metano e l?anidride carbonica espulsi dalla cavit? orale e anale dei bovini ed ottenendo energia termica ed elettrica a seguito della loro combustione. Purpose of the present invention? is to reduce the environmental impact of cattle breeding and make the entire breeding establishment energy independent, starting from the methane and carbon dioxide expelled from the cavity. oral and anal of cattle and obtaining thermal and electrical energy following their combustion.
Il sistema in questione, pensato integrato all?allevamento bovino, ? composto da tre fasi: l?aspirazione, la filtrazione e la cogenerazione. Tutte e tre aventi come oggetto la miscela gassosa, comprendente i gas serra metano e anidride carbonica espulsi dalle cavit? orale e anale dei bovini, presente all?interno dello stabilimento. L?aspirazione avverrebbe grazie a cappe aspiranti posizionate strategicamente in posizioni favorevoli all?intercettazione dei gas emessi dalla cavit? boccale dei bovini, in quanto da essa deriva il 97% delle emissioni in questione. The system in question, designed to be integrated with cattle breeding, is composed of three phases: suction, filtration and cogeneration. All three having as their object the gaseous mixture, including the greenhouse gases methane and carbon dioxide expelled from the cavities? oral and anal of cattle, present inside the plant. The extraction would take place thanks to extractor hoods strategically positioned in positions favorable to the interception of the gases emitted from the cavity. bovine mug, as 97% of the emissions in question derive from it.
La miscela gassosa, una volta intercettata dalle cappe aspiranti, viene convogliata in condotti, i quali la indirizzeranno nell?impianto di cogenerazione per la trasformazione in energia elettrica e termica. All?interno di questi condotti pu? essere prevista l?installazione di filtri deputati all?eliminazione di eventuali impurit? aspirate presenti nell?atmosfera interna lo stabilimento dell?allevamento bovino. Tale passaggio pu? avere una duplice funzione: evitare danni all?impianto di cogenerazione ed aumentare il potere calorifico della miscela gassosa combusta dall?impianto stesso. Una volta prodotta energia elettrica e termica, queste possono essere usate per il sostentamento energetico dello stabilimento o destinate ad altri fini a piacimento dell?allevatore, a questo punto in grado di guadagnare o in termini di risparmio o in termini di vendita ai gestori di rete l?energia prodotta. The gaseous mixture, once intercepted by the extractor hoods, is conveyed into ducts, which will direct it to the cogeneration plant for transformation into electrical and thermal energy. Inside these ducts can? be expected to install filters designed to eliminate any impurities? aspirate present in the internal atmosphere of the cattle breeding establishment. This passage can have a dual function: avoid damage to the cogeneration system and increase the calorific value of the gaseous mixture combusted by the system itself. Once electrical and thermal energy has been produced, these can be used to sustain the plant's energy or used for other purposes as desired by the farmer, who is at this point able to earn either in terms of savings or in terms of sales to network operators. the energy produced.
