Biogas chirimwa chembwa

Musi waGunyana 1, 2010, gwenya rekutanga repasi rose rebiogas rinofambiswa netsvina yembwa rakavhurwa mupaki muCambridge, Massachusetts. Iyi purojekiti isinganzwisisike kuyedza kutarisa kutsva kwekurasa tsvina uye kuwana simba kubva kune "exotic" avo. sources.

Tsvina yembwa inoshandurwa kuita magetsi epaki

Mugadziri ane makore makumi matatu nematatu ekuAmerica muimbi Matthew Mazzotta. Chisikwa chake chazvino chinodaidzwa kuti Park Spark. Iyo system inosanganisira peya yematangi. Mune imwe yadzo, methane (anaerobic) kuvirisa kunoitwa, uye mune yechipiri, huwandu hwemvura mune yekutanga hunodzorwa. Rambi regesi rakaiswa pedyo nematangi. Mwenje unopihwa biogas kubva mutsvina yembwa. Vanofamba nembwa vanorayirwa kuti vatore mabhegi anogona kuparara, voaisa mumudziyo pedyo neimba yemwenje, votora zvinosiya imbwa pauswa, vokanda mabhegi acho muchiviriso. Ipapo iwe unofanirwa kutenderedza vhiri parutivi rwetangi, izvi zvinosanganisa zviri mukati. Seti yebhakitiriya inogara mutangi inotanga kushanda, uye mushure mechinguva, biogas ine methane inooneka. Kunyanya kushingaira kwevaridzi, kuchenesa tsvina yembwa dzavo mutangi, iyo inopisa moto wekusingaperi usingagumi.

Iyo gasi yakatsva inofanirwa kuvhenekera chikamu chenzvimbo yakapoteredza chirimwa, asi mushure mekuunganidza hurongwa hwake, VaMazzotta vakamhanyira mumatambudziko akawanda. Pakutanga zvakazoitika kuti yaive nechaji shoma yekunyatso tanga mudziyo? uye acharipira imbwa dzose dziri muguta kuti dzipedze. Mukuwedzera, tangi yaifanira kuzadzwa nemabhakitiriya akakodzera, asi akanga asiri pedyo. Pakupedzisira, munyori nevamwe vake vakatozogadzirisa zvese nekuunza ndove yemombe kubva kumapurazi aive pedyo.

Rimwe dambudziko raiva remvura. Iyo inoshandiswa muPark Spark haifaniri kunge iine chlorine, iyo inokuvadza kune maitiro ekuvirisa, i.e. haigoni kuva mvura yemuguta. Mazana anoverengeka marita ehumwe H.₂Yakaunzwa kubva kuRwizi rwaCharles. Uye, kunyangwe nekuedza kwavo kwakanyanya, vataridzi havana kubva vaona mwenje wemethane wakashambadzirwa uchishanda. Kuvirisa kwakatanga, asi padanho rekutanga pakanga paine methane shoma yekuti rambi ribatike. Vanyori vakatsanangurira vataridzi kuti mukati metangi, mabhakitiriya emethane anofanira kutanga awanda kusvika pachiyero chakakodzera, apo kukura kwavo kwakaderedzwa nekuda kwehusiku hunotonhora. Inopfuura vhiki yakapfuura gasi rakawanda kwazvo risati ragadzirwa zvokuti raigona kubatidzwa.

Sezvineiwo, murazvo wayo weblue waive mudiki zvekuti zvaisaita kuti utore mufananidzo pasi pechiedza chakajeka chemamwe marambi. Ipapo yakawedzera zvishoma nezvishoma uye nokudaro pakupedzisira yakaruramisa kuvepo kwese kuisirwa gasi rehunyanzvi. Mhedzisiro chaiyo yekuisa haisi kupenya kwemurazvo, asi hype mumapepanhau. Munyori akaverengera kubatanidzwa kwevanhu vakawanda sezvinobvira mudambudziko rekuraswa kwemarara zvine musoro. Maererano nemuimbi, chiedza chine mwero murambi chimwe chinhu chakaita semurazvo usingaperi, uchiyeuchidza vanopfuura-nekudikanwa kwekuchengetedza zvisikwa, kuderedza kuburitswa kwegasi rinopisa uye kuve nekugadzira mukugadzira simba. Munyori haatsvaki kuwana chero rubatsiro rwemari kubva kubasa rake.

Biogas yakakura

Kuiswa kwaMazzotta kunonakidza kwazvo, asi ingori maungira ezvirongwa zvakakomba. Pfungwa yekushandura tsvina yembwa kuita simba yakazvarwa muSan Francisco makore mana apfuura. Sunset Scavenger, kambani yekurasa marara yakazonzi Norcal, yaida kuita mari.

Nyanzvi dzavo dzinofungidzira kuti muSan Francisco Bay Area, tsvina yembwa inoita 4% yemarara ese epamba, anokwikwidza manapukeni muhuwandu. Uye izvo zvinoreva zviuru zvematani ezve organic zvinhu. Masvomhu, uku ndiko kugona kwakanyanya kwebiogas. Nechiyedzo, Norcal akatanga kunhonga marara embwa achishandisa midziyo yemabhegi anoodegradable poop uye matengu kuti atore "mabhegi" akazara munzvimbo dzinowanzoshanyirwa nembwa dzinofamba. Chirimwa ichi chakazoendeswa kune imwe yemiti yaivepo yebiomethane.

Zvisinei, muna 2008 chirongwa chacho chakavharwa. Kuunganidzwa kwendove yembwa mumapaki kwakakundikana nezvikonzero zvemari chete. Kutora tani yemarara kuenda kunoraswa kwakachipa pane kutanga chirongwa chebioenergy, uye hapana ane hanya kuti imafuta akawanda sei aunowana kubva kwairi.

Mutauriri weSunset Scavenger Robert Reid akacherekedza kuti aya mabhegi anoora, iwo ega anotenderwa kukandwa mumethane fermenter, ave tabhu pachikero. Vazhinji varidzi vembwa vakadzidziswa kuchenesa mushure mekunge zvipfuwo zvavo zvajaira kushandisa mabhegi epurasitiki, ayo anobva amisa maitiro ese ekuumbwa kwemethane.

Kana iwe uchida kuti varidzi vembwa vagare vaine marara akakosha kuti aenderere mberi nekugadzirisa mumethane, unofanirwa kuisa midziyo ine mabhegi anogona kuparara kwese kwese. Uye mubvunzo unoramba usina kupindurwa, sei kutarisa kana mabhegi epurasitiki akakandwa mumabhasikiti?

Panzvimbo pesimba rembwa, Sunset Scavenger, pamwe chete nemamwe makambani, akatanga kubudisa simba "kubva muresitorendi", ndiko kuti, vakatanga kuunganidza marara ezvokudya, vachiendesa kune mamwe matangi ekuvirisa.

Varimi vanoshanda zviri nani

Mhou dziri nyore. Matanga anogadzira huwandu hwefetereza mumaindasitiri. Ndosaka zvine pundutso kuvaka nzvimbo hombe dzebiogas mumapurazi kana munharaunda dzekurima. Izvi zvinomera zvebiogas hazvingobudisi simba repurazi, asi dzimwe nguva kunyange kutengesa kune grid. Makore mashoma apfuura, chirimwa chekugadzira mupfudze wemombe 5 kuita magetsi chakatangwa muCalifornia. Chirongwa ichi chinonzi CowPower, chinonzi chabatsira zviuru nezviuru zvedzimba. Uye BioEnergy Solutions inoita mari pane izvi.

High tech fetereza

Nguva pfupi yadarika, vashandi veHewlett-Packard vakazivisa zano renzvimbo dzedata dzinofambiswa nemapfudze. PaASME International Conference muPhoenix, HP Lab masayendisiti akatsanangura kuti mombe zviuru gumi dzinogona kusangana nezvinodiwa zvesimba zve10MW data center.

Muchiitiko ichi, kupisa kunokonzerwa nedata data kunogona kushandiswa kuvandudza kushanda kweanaerobic digestion yemarara emhuka. Izvi zvinoguma nekugadzirwa kwemethane, iyo inogona kushandiswa kugadzira simba munzvimbo dze data. Iyi symbiosis inobatsira kugadzirisa dambudziko remarara rakatarisana nemapurazi anotarisana nemukaka uye kudiwa kwesimba munzvimbo yemazuva ano data.

Paavhareji, mombe yemukaka inobereka anenge 55 kg (120 pounds) emupfudze pazuva uye anenge matani 20 pagore? iyo inenge inoenderana nehuremu hwenzou ina dzakura. Ndove inogadzirwa nemhou zuva rega rega inogona "kuburitsa" 3 kWh yemagetsi, inokwana simba matatu ekuAmerica maTV kwezuva.

HP inoratidza kuti varimi vanogona kurenda nzvimbo kumasangano epamusoro-soro, vachivapa "brown energy". Muchiitiko ichi, mari yemakambani mumiti yemethane ichabhadhara mumakore asingasviki maviri, uye ivo vachawana mari inosvika zviuru zviviri zvemadhora pagore kubva pakutengesa methane simba kune vatengi venzvimbo yedata. Varimi vanozove nemari yakagadzikana kubva kumakambani eIT, ivo vachange vaine nyore sosi yesimba uye mufananidzo wevanoongorora zvakatipoteredza. Tese taizove nemethane shoma mumhepo yedu, zvichiita kuti isanyanya kunetseka nekudziya kwepasi. Methane ine inodaidzwa kuti greenhouse inogoneka kakapetwa ka2 pane yeCO₂. Nekubuda mupfudze usingabereki, methane inoramba ichiumbwa zvishoma nezvishoma uye ichiburitswa mumhepo, uye inogonawo kusvibisa mvura yepasi. Uye kana methane yapiswa, carbon dioxide haina ngozi sezvairi.

Nokuti zvinokwanisika kushandisa nesimba uye nehupfumi izvo zviri kuputsika muminda uye mashizha, uye izvi zvinonyanya kuoneka kana chando chechando chanyunguduka. Asi zvakakosha here? Asi imbwa inovigwa.
