El biogas Lelinye lawona mandla azinzileyo nathembisayo avuselelekayo, ngakumbi kwimimandla yasemaphandleni okanye ngaphandle kokufikelela kwigesi yendalo engundoqo. Iveliswa ngenkqubo yokubola kwezinto eziphilayo ngenxa yesenzo sebhaktiriya ye-anaerobic kwindawo engena-oxygen. Oku kubangela umxube weegesi, ingakumbi i-methane (CH4) kunye nekhabhon dayoksayidi (CO2), engasetyenziselwa ukufudumeza, ukupheka, ukuvelisa umbane kunye nezinye izicelo zoshishino.
Yintoni i-biogas kwaye iveliswa njani?
I-Biogas yirhasi yamafutha efunyenwe ekuboleni kwenkunkuma ephilayo. Itekhnoloji evumela imveliso yayo ibizwa ngokuba biodigester, inkqubo equlethe izinto eziluhlaza (inkunkuma yokutya, umgquba, i-sewage sludge, njl.) kwaye idala indawo engena-oksijini ukwenzela ukuba ibhaktheriya ye-anaerobic isebenze. Le nkqubo ivelisa i-methane, eyona nxalenye iphambili ye-biogas kwaye inoxanduva lwexabiso layo lamandla.
Imetabolism yezi bhaktheriya iguqula ngokuthe ngcembe izinto eziphilayo zibe yi-biogas ngokwamanqanaba ahlukeneyo, kubandakanywa:
- IHydrolysis: Iimolekyuli ezinkulu zezinto eziphilayo ziyaqhekeka zibe ziimolekyuli ezilula.
- I-Acidogenesis: Ukuguqulwa kwezi molekyuli zibe ziiasidi eziguquguqukayo zamafutha kwenzeka.
- I-acetogenesis: Iiasidi ezinamafutha ziguqulwa zibe yiacetic acid, ihydrogen kunye necarbon dioxide.
- IMethanogenesis: Inqanaba lokugqibela apho iintsholongwane zivelisa imethane necarbon dioxide.
Amacandelo eBiodigester
I-Biodigesters inokwahluka ngobukhulu kunye nobunzima, ukusuka kwiinkqubo ezincinci zokusetyenziswa ekhaya ukuya kwizityalo ezinkulu zemizi-mveliso. Nangona kunjalo, zonke zabelana ngezinto ezisisiseko:
- Itanki yokutya: Apha i-biomass ifakwe, ekufuneka icoliwe ukuze iququzelele inkqubo yokubola.
- Isixhobo se-Anaerobic: Yindawo apho i-biomass icutshungulwa khona, iphazamiseke kwaye ivundiswe, ivumela ibhaktheriya ukuba isebenze ngokufanelekileyo.
- Inkqubo yokubamba igesi: Iigesi ezenziwe kwi-digester ziyaqokelelwa kwaye zigcinwe ukuze zisetyenziswe kamva.
- Itanki yokukhupha: Ulwelo kunye nenkunkuma eqinileyo iyaqokelelana apha, enokuthi iphinde isetyenziswe njengesichumiso.
Ukusetyenziswa kwe-Biogas
I-Biogas ingasetyenziswa kumacandelo amaninzi, igxininisa ukuguquguquka kwayo:
- Ukuveliswa kombane: Ukutsha kwe-biogas kwiijenereyitha kunokuvelisa umbane ngokufanelekileyo.
- Ukufudumeza nokupheka: Ingasetyenziswa kwiibhoyila zokufudumeza okanye ekhitshini, njengerhasi yendalo.
- Amafutha emoto: I-Biogas inokucocwa ukuze ivelise i-biomethane, enokusetyenziswa njengamafutha ezithuthi.
- Ukuveliswa kwezichumisi: I-digestate, i-by-product ye-biodigester, ngumthombo obalaseleyo wezondlo ezinokuthatha indawo yezichumisi zemizi-mveliso.
I-Biogas kunye noqoqosho lwesetyhula
Umxholo we Uqoqosho olujikelezayo Ikwakhona nasekusetyenzisweni kwe-biogas. Ngokusebenzisa inkunkuma ephilayo enokuthi ilahlwe ngokubanzi kwiindawo zokulahla inkunkuma, ukuveliswa kweegesi ze<em>greenhouse ezifana ne<em>methane kunye ne<em>carbon dioxide kuyaphetshwa, kwaye kwenziwa inkqubo yokusetyenziswa kwakhona evumelana nokusingqongileyo.
Ngale ndlela, amacandelo ezolimo kunye nemfuyo ayinakukwazi ukunciphisa i-carbon footprint ngokusebenzisa i-biogas ukuvelisa amandla kunye nezichumisi, kodwa banokwenza imali ngenkunkuma eyenziwa ngumsebenzi wabo.
Iinzuzo zeBiogas
- Ngamandla ehlaziyekayo kwaye iyafikeleleka.
- Ukunciphisa Ukukhutshwa kweegesi zegreenhouse.
- Guqula inkunkuma ibe yimithombo eluncedo, ukukhuthaza Uqoqosho olujikelezayo.
- Ibonelela ngokuzimela kwamandla kwinqanaba lendawo.
Kucacile ukuba i-biogas inamandla amakhulu okuba ngumthombo oyintloko wamandla acocekileyo. Nangona kunjalo, ukuze lo mandla ombane aphumelele, kubalulekile ukwandisa ulwazi malunga nokubaluleka kokulawula ngokufanelekileyo inkunkuma yezinto eziphilayo kunye nokukhuthaza ukuthatha inxaxheba koluntu ekufakeni i-biodigesters, ngakumbi kwiindawo apho igesi engundoqo ingafiki.
Ehlabathini lonke, kukho imizekelo emininzi eyimpumelelo yokusebenzisa i-biogas njengomthombo wamandla. IYurophu, umzekelo, sele inamaziko angaphezu kwama-60 okucocwa kwenkunkuma ephilayo evelisa i-biogas. Ukubambelela kolu hlobo lwezisombululo zamandla kunokufaka isandla kakhulu kumlo ochasene nokutshintsha kwemozulu, ngelixa ukhuthaza ulawulo lwenkunkuma olusebenzayo nolunenzuzo kokusingqongileyo.
