Zvese zvaunoda kuti uzive nezve biogas uye kugadzirwa kwayo

Kune akawanda masosi esimba rinodzokororwa, semhepo, solar, geothermal, hydraulic, pakati pevamwe. Nhasi tichaongorora sosi yesimba rinogoneka iro, kunyangwe risingazivikanwe seyapfuura, rine hukuru hukuru. Tiri kutaura nezve biogas.

Biogasi igasi kubva mukuora kweiyo organic matter iyo, pakati pezvimwe zvinobatsira, yakachena uye inodzokororwa simba. Muchinyorwa chino tichaongorora maitiro ekugadzira, mashandisiro, zvakanakira, zvisingabatsiri uye nezvimwe. Iwe unoda kuziva zvakadzama zvese zvine chekuita nebiogas?

Biogas hunhu

Biogas igasi rinogadzirwa kubva mukuora kwe organic matter. Izvi zvinowanzoitika munzvimbo dzisina oxygen kana mumidziyo yakavharwa inonzi biodigesters. Igasi rinoumbwa kunyanya methane uye carbon dioxide, iyo pamwe chete inomiririra pakati pe60% ne90% yehuwandu hwayo. Mukuwedzera, inosanganisira zviduku zvezvimwe zvikamu zvakadai sehydrogen, nitrogen uye hydrogen sulfide.

Methane Ndicho chinhu chakakosha chebiogas sezvo, segasi rechisikigo, rinopisa zvakanyanya uye saka rinoshanda semafuta.

Hunhu hwebiogas hunoita kuti ive sarudzo inogoneka kugadzira magetsi, kupisa, uye kunyangwe sebiofuel, iyo inoiisa seimwe nzira inogona kudzokororwa kune fossil fuels.

Biogas inogadzirwa sei?

Kugadzirwa kwebiogas kunotevera nzira inonzi anaerobic digestion, iyo inosanganisira kuparara kwezvinhu zvakasikwa nema microorganisms pasina oxygen. Tsvina dzakasiyana-siyana dzinogona kushandiswa, kubva mundove yemhuka, marara ekurima, kusvika kune tsvina yesuweji nemarara emumaguta.

Iyo nzira yakakamurwa kuita nhanho ina:

• Hydrolysis: Mamorekuru makuru eorganic matter akakamurwa kuita makomisheni ari nyore.
• Acidgenesis: Microorganisms inoshandura makemikari aya kuita fatty acids, alcohols uye CO2.
• Acetogenesis: Acids inoshandurwa kuita acetate uye hydrogen.
• Methanogenesis: Methane uye CO2 inogadzirwa, ichigadzira biogas inobatsira sehuni.

Kuparara kunoitika mukati biodigesters, iyo yakavharwa, midziyo isina mhepo yakagadzirirwa kugadzirisa mamiriro ekuora. Midziyo iyi inogona kusiyanisa muhukuru uye kugona, kubva kumidziyo midiki yemumba kuenda kune yakakura maindasitiri zvirimwa.

Simba rinogona kuitika

Biogas ine simba guru resimba; Ne cubic meter imwe chete yebiogas zvinokwanisika kugadzira magetsi anosvika 2 kWh, izvo zvakaenzana nekushandisa maawa matanhatu echiedza mugirobhu remwenje 60-watt kana kuisa simba mufiriji diki, inoshanda zvakanyanya kweawa imwe.

Kana ichienzaniswa nezvimwe zvinogadzirwazve, biogas ine mukana wekukwanisa kushandiswa kupisa, kubika uye kugadzira magetsi, kutora mukana wezvinhu zvakasiiwa zvingangosiiwa semarara mumarara. Uyewo hazvibvi pamamiriro ekunze akadai sesimba rezuva kana remhepo.

Chii chinonzi biodigester?

A biodigester chinhu chakavharwa, chakavharwa chisimbiso apo organic tsvina inotenderwa kuora kuti igadzire biogas. Midziyo iyi inogona kuwanikwa mudzimba, mapurazi madiki kana maindasitiri. Mabiodigester haangobudisi methane gasi chete asi anoburitsawo chigadzirwa chinonzi digestate, chinogona kushandiswa sefotereza ine chikafu chakapfuma.

Nyika dziri kutungamira mukuunza biodigester pamwero mukuru dzinosanganisira Germany, China neIndia. MuLatin America, nyika dzakaita seBrazil neArgentina dzakaitawo budiriro huru mukushandisa tekinoroji iyi kudzikisira kukanganiswa kwezvakatipoteredza uye kugadzira simba nenzira yakagadzikana.

Ikozvino kushandiswa kwebiogas

Biogas ine mashandisirwo akasiyana-siyana kubva pakugadzira magetsi muzvirimwa zvemaindasitiri kusvika pakushandisa mudzimba kupisa nekubika. Munyika dzakawanda, biogas inoshandiswa kugadzira simba kubva kumarara ekurima uye tsvina yesuweji. MuArgentina, semuenzaniso, biogas inoshandiswa kurapa kunyarara, chibereko chenzimbe chinogadzirwa mukati mekuita kwayo maindasitiri.

Kumaruwa, zvakanakira biogas zviri pachena. Inopa simba rinosvikirika kunzvimbo dziri kure uye zvinobatsira zvekurima nezvigadzirwa, senge organic fetereza, nemutengo wakaderedzwa. Uyezve, nekudzora zvirinani kusvibiswa kweorganic nebiodigesters, isu tinobatsira mukuderedza matambudziko ezvakatipoteredza sekuburitswa kwemagasi egreenhouse.

Biogas iri kushandiswawo mumaraini emazuva ano, izvo zvinoita kuti pave nemukana wekushandisa gasi remethane rinogadzirwa nekuora kwemarara. Maguta mazhinji akadai saSantiago de Chile akatotanga kushandisa biogas sechipo chesimba mugasi rechisikigo rekugovera network.

Ramangwana rinogona kuita biogas

Biogas ine ramangwana rakajeka nekuda kwekugona kwayo kuderedza tsvina uye kugadzira simba rakachena. Sezvo tekinoroji iri kufambira mberi, kushandiswa kwebiodigester kunogona kuita basa uye kusadhura, izvo zvichabatsira mukutorwa kwakanyanya kwerudzi urwu rwesimba munyika dzichiri kusimukira neavo vane zvikamu zvakakura zvekurima nezvipfuyo.

Pamusoro pezvo, hunyanzvi hunoshanda huri kugadzirwa hwekuvirisa uye kubviswa kwebiogas, iyo inovimbisa kuwedzera kushandiswa kwayo padanho reindasitiri. Pasina kupokana, biogas ichava imwe yembiru mukushanduka kuenda kumhando dzehupfumi dzakatenderedzwa, uko tsvina inodzokororwa kuita manyuko matsva esimba uye zviwanikwa zvinogona kushandiswa.

Biogas haingobatsiri kudzikisira kushanduka kwemamiriro ekunze, asi inogonawo kushandura marara kuti ive renewable simba sosi uye anobatsira byproducts akadai fetiraiza, zvichiratidza kugona kwayo sechikamu chepasi rose simba remangwana.
