El biogas Ndiyo imwe yesimba rinogoneka uye rinovimbisa kudzokororwazve simba, kunyanya kunzvimbo dzekumaruwa kana kusawana mains chaiwo gasi. Iyo inogadzirwa kuburikidza nemaitiro ekuora kweiyo organic zvinhu nekuda kwekuita kweanaerobic bhakitiriya munzvimbo isina oxygen. Izvi zvinopa musanganiswa wemagasi, kunyanya methane (CH4) uye kabhoni dhayokisaidhi (CO2), iyo inogona kushandiswa kupisa, kubika, kugadzira magetsi uye mamwe maindasitiri ekushandisa.
Chii chinonzi biogas uye inogadzirwa sei?
Biogasi igasi rehuni rinowanikwa kubva mukuora kwemarara. Iyo tekinoroji inobvumira kugadzirwa kwayo inonzi biodigester, hurongwa hune zvinhu zvakasvibirira (marara ezvokudya, manyowa, tsvina yemvura, nezvimwewo) uye inogadzira nzvimbo isina oxygen kuitira kuti mabhakitiriya eanaerobic aite. Iyi nzira inogadzira methane, inova chikamu chikuru chebiogas uye inotarisira kukosha kwayo kwesimba.
Iyo metabolism yemabhakitiriya aya zvishoma nezvishoma inoshandura organic matter kuita biogas mumatanho akasiyana, kusanganisira:
- Hydrolysis: Mahombe organic mamorekuru anoputsika kuita mamorekuru akareruka.
- Acidgenesis: Shanduko yemamorekuru aya kuita volatile fatty acids inoitika.
- Acetogenesis: Fatty acids inoshandurwa kuita acetic acid, hydrogen uye carbon dioxide.
- Methanogenesis: Danho rekupedzisira apo mabhakitiriya anobudisa methane necarbon dioxide.
Biodigester zvikamu
Biodigesters inogona kusiyana muhukuru uye kuoma, kubva kudiki masisitimu ekushandisa pamba kusvika kune makuru maindasitiri zvirimwa. Nekudaro, vese vanogovana zvakakosha zvinhu:
- Feed tank: Pano iyo biomass yakaiswa, iyo inofanirwa kupwanywa kuti ifambise maitiro ekuora.
- Anaerobic reactor: Ndiyo nzvimbo iyo iyo biomass inogadziriswa, kubvongodzwa uye kuviriswa, zvichiita kuti hutachiona hushande nemazvo.
- Gas capture system: Iwo magasi anogadzirwa mu digester anounganidzwa uye anochengetwa kuti ashandiswe gare gare.
- Dicharge tank: Tsvina yemvura uye yakasimba inoungana pano, inogona kushandiswa zvakare sefotereza.
Biogas kushandiswa
Biogas inogona kushandiswa muzvikamu zvakawanda, ichiratidza kushandiswa kwayo kwakasiyana-siyana:
- Kugadzira magetsi emagetsi: Kupisa kwebiogas mumajenareta kunogona kugadzira magetsi nemazvo.
- Kupisa uye kubika: Inogona kushandiswa mumaboilers ekudziya kana mukicheni, senge gasi rechisikigo.
- Mafuta emotokari: Biogas inogona kucheneswa kugadzira biomethane, iyo inogona kushandiswa semafuta emotokari.
- Kugadzirwa kwefertilizer: Iyo digestate, iyo by-chigadzirwa chebiodigester, inzvimbo yakanaka kwazvo yekudya kunotsiva fetereza yemumaindasitiri.
Biogas uye denderedzwa hupfumi
Pfungwa ye denderedzwa hupfumi Inowanikwawo mukushandiswa kwebiogas. Nekutora mukana wemarara emarara ayo anowanzoraswa mumarara, kugadzirwa kwemagasi egreenhouse akadai semethane necarbon dioxide kunodziviswa, uye hurongwa hwekushandisa zvakare hunogadzirwa hunofarira zvakatipoteredza.
Nenzira iyi, zvikamu zvekurima uye zvipfuyo hazvingogone kuderedza kabhoni yavo nekushandisa biogas kugadzira simba nefetereza, asi vanogona zvakare kuita mari tsvina inogadzirwa nebasa ravo.
Biogas inobatsira
- Isimba dzokororo uye inosvikika.
- Deredza Emissions yegreenhouse magasi.
- Shandura tsvina kuita zviwanikwa zvinobatsira, kusimudzira denderedzwa hupfumi.
- Inopa simba rekuzvimirira panzvimbo yenharaunda.
Zviripachena kuti biogas ine mukana mukuru wekuva sosi yekutanga yesimba rakachena. Zvisinei, kuti simba iri rive rinobudirira, zvakakosha kuwedzera ruzivo pamusoro pekukosha kwekugadzirisa zvakanaka tsvina yehupenyu uye kukurudzira kubatanidzwa kwevanhu mukuiswa kwebiodigester, kunyanya munzvimbo dzisingasviki gasi guru.
Pasi rose, kune mienzaniso yakawanda yakabudirira yekushandisa biogas sesimba rinobva. Europe, semuenzaniso, inotova nemafekisheni anopfuura makumi matanhatu emarara anoburitsa biogas. Kuomerera kune rudzi urwu rwemagetsi ekugadzirisa zvinogona kubatsira zvakanyanya mukurwisana nekushanduka kwemamiriro ekunze, uku uchikurudzira zvakanyanya kushanda uye kunobatsira kuchengetedzwa kwemarara.
