Yini I-Digester Vessel Okufanele Iyenze Esitshalweni Se-Anaerobic?
I-'biogas tank' eyodwa iwumbono oyiphutha. Isitshalo se-anaerobic digestion (AD) siwuchungechunge lwezitsha, ngasinye sinomsebenzi ohlukile, futhi ukuzidida kuholela ekucacisweni okungalungile.
Ngamafuphi: isitsha esisodwa siyagaya, ezinye zibhafa ukuphakelwa, zigcine igesi futhi zigcine i-digestate. Ngasinye sakhelwe uketshezi oluhlukile, igesi kanye nomsebenzi wengcindezi ohlukile.
Esitshalweni se-AD, 'i-digester' iyisitsha esivaliwe, esishisisiwe, esixutshiwe lapho ama-microorganism ephula khona izinto eziphilayo zibe yi-biogas ne-digestate. Eduze kwaso kukhona izitsha ezisekelayo: indawo yokwamukela nokubhafa ukuphakelwa, isitsha segesi, kanye nesitoreji se-digestate. Ndawonye zakha uhlelo lokugcina.
Izici Eziyisisekelo, Izingxenye Nezinhlobo
Ukutholwa nokugcinwa kwesondlo: Kubamba isondlo esingenayo (ubulongwe, izitshalo zamandla, imfucuza yokudla) amaviki angu-1-2 ukuze kuncishiswe ukuphazamiseka kokuhlinzekwa nokulungiselela isondlo ngaphambi kokusetshenziswa.
I-Digester (CSTR noma okufanayo): Isiphenduli esiyinhloko, ngokuvamile siba ku-35-38 C (mesophilic) noma 50-55 C (thermophilic), sigcinwa izinsuku ezingama-20-40 futhi sixutshwa ngokuqhubekayo. Kufanele singavumi ukungena komoya futhi sifudunyezwe.
Isigcina-gesi: Isigcina-gesi esihlukile noma esiyingxenye (ngokuvamile uphahla olunamangqamuzana amabili) esihlukanisa ingcindezi ye-digester ekufuneni kwe-CHP noma ukuthuthukiswa kwegesi.
Isigcina se-digestate: Ichibi noma ithangi elilinganiswe nesizini yokusabalalisa kanye nemithetho, hhayi umkhiqizo wansuku zonke kuphela.
Izinhlelo Zokusebenza Nezimo Zokusetshenziswa
I-Farm ne-manure AD, i-food-waste ne-industrial-effluent biogas, i-wastewater sludge digestion, kanye ne-landfill-gas-adjacent organics recovery konke kusebenzisa leli ketanga lemikhumbi, ngosayizi kusuka kumakhulu ambalwa kuya ezinkulungwaneni ezingamashumi eziningi zama-cubic metres.
Ukucatshangelwa Kwezobuchwepheshe
I-digester iyisitsha esisodwa kuphela okufanele ngasikhathi sinye singavuzi igesi, sishiselwe, sixutshwe futhi sizinzile ngokwebhayoloji. Igobolondo laso libona igesi efudumele, engena-oksijini, ene-H2S ngaphezu komugqa woketshezi kanye ne-liquor enolaka ngaphansi. Izitsha ezisekelayo zinemisebenzi elula: i-buffer ayishisi futhi ivamise ukuvuleka, isigcini segesi sibamba umfutho ophansi (5-30 mbar), kanti isitoreji se-digestate asinyakazi kakhulu.
Cacisa isitsha ngasinye ngokomsebenzi waso esikhundleni sokwakha ngokweqile lezo ezilula. Ukushisa, ukuxuba kanye nokuphathwa kwegesi kuhlanganiswe egobolondweni le-digester, ngakho-ke indawo yomlomo wokuphuma kanye nendawo yokumboza kufanele kuhlelwe njengohlelo olulodwa.
Izinzuzo Nezithiyo
Izinzuzo:
Ukuhlukanisa imisebenzi kuvumela isitsha ngasinye ukuthi silinganiswe kahle futhi simbozwe ngendlela efanele: i-digester ithola isembozo esingavuzi igesi, esimelana ne-asidi/H2S; ama-buffer namathangi e-digestate agwema ukukhokhela ukuvikeleka kwegesi okungadingekile.
Izithiyo:
Iketanga linamandla kuphela ngokwesitsha salo esibuthakathaka kunazo zonke. Ukungabi namandla okubhafa kubangela ukuphazamiseka kokuphakelwa; isitsha segesi esincane siphoca i-digester ukuthi igibele ukushintshashintsha kwengcindezi; isitoreji se-digestate esinganele sidabula imithetho yokusabalalisa. Isitsha ngasinye kufanele sicaciswe ngomsebenzi waso wangempela.

Izinqubo Ezinhle Kakhulu & Indlela Yokukhetha
Dweba lonke uchungechunge lwe-containment ngaphambi kokucacisa noma yiliphi ithangi elilodwa. Linganisa ibhafa ngokuthembeka kokuphakelayo kwakho, i-digester ngokugcinwa nokushisa umthwalo, isibambi segesi ngokushintshashintsha kwesidingo, kanye nesitoreji se-digestate ngokomthetho nesizini. Hlanganisa ukushisa, ukuxuba kanye nama-nozzle egesi ekwakhiweni kwe-digester kusukela ekuqaleni.
Umsebenzi womkhumbi we-digester ukuguqula izinto eziphilayo zibe yi-biogas ngaphansi kwezimo ezivaliwe, ezishisayo, ezixutshiwe. Kodwa ungomunye wemikhumbi emine ochungechungeni; ukucacisa ngayinye emsebenzini wayo wangempela yikho okwenza isitshalo sithembeke.
Imibuzo Evame Ukubuzwa (FAQ)
Uyini umehluko phakathi kwe-digester nesibambi segesi?
I-digester iyisitsha esivaliwe, esishisisiwe, esixutshiwe lapho kukhiqizwa khona i-biogas. Isigcina-gesi sigcina lelo gesi ngengcindezi ephansi ukuze silinganise ukunikezwa nesidingo se-CHP noma sokuthuthukisa; akusona lapho kwenzeka khona ukugaya.
Kungani izitshalo ze-AD zidinga ithangi lokugcina ukudla?
Ukulethwa kwezinto zokudla kuyenzeka ngezikhathi ezithile kodwa ukugaya kudinga ukufakwa okungaguquki. Isigcina-masonto angu-1-2 siqeda ukuphazamiseka, silungiselela ukudla kusengaphambili futhi sivikele i-biology ye-digester ekuphazamisekeni.
I-digester isebenza kuphi izinga lokushisa?
Iningi lisebenza nge-mesophilic ku-35-38 C noma i-thermophilic ku-50-55 C. Igobolondo, ukushisa kanye nokufaka insulate kufanele kubambe lelo bhendi; ukushintshashintsha kwama-degree ambalwa kwehlisa ngokubonakalayo ukuguqulwa.
Ingabe impahla ihlala isikhathi esingakanani ku-digester?
Ukugcinwa ngokuvamile kuyizinsuku ezingama-20-40 kuye nge-feedstock kanye nezinga lokushisa. Leso sikhathi sokuhlala, hhayi umthamo wethangi kuphela, sichaza usayizi we-digester.
Ingabe isitoreji se-digestate siyithangi ngempela?
Kungaba yithangi noma i-lagoon, kodwa kufanele ilinganiswe nesizini yokusabalalisa kanye nemithetho yezemvelo, hhayi umkhiqizo wansuku zonke kuphela. Ukungayilinganisi kahle kuyiphutha elivamile lokuhambisana nemithetho.
