Liyini Ithangi Legesi Elivela Emfucumfucwini? Ukuklanywa Kokugcina, Izinto Zokwakha kanye Nezindinganiso Zokuphepha
Ithangi le-biogas yisitsha esingangeni umoya esikhiqiza i-biogas — njenge-digester — noma esigcina i-biogas ngemva kokukhiqizwa, ngokuvamile ngomfutho ophansi onama-55–75% e-methane. Amathangi e-biogas anamuhla ahlanganisa izindonga ze-GFS (glass-fused-to-steel) noma ze-stainless nezingqimba zophahla ezenziwe ngobunjiniyela kanye nama-gas holder anezembozo eziphindwe kabili eziqinisekisiwe ukuthi awangeni umoya.
I-biogas eluhlaza iyisakhamuzi esingalungile: i-H2S nokufuma kwayo kugcwala kube i-sulfuric acid encibilikile ezindongeni ezipholile, kuyilapho noma yikuphi ukuvuza kungukulahlekelwa kwemali nokuyingozi yokuphepha. Ngakho-ke ithangi le-biogas liphumelela noma lihluleke ngezindlela ezimbili — ubunjiniyela bokugqwala kanye nokuqinisekiswa kokungangeni umoya.
1. Umsebenzi Wethangi Le-Biogas Yini Esitshalweni Se-Biogas?
Isitsha sokucubungula (umsebenzi we-digester): Njenge-digester ehlanganisa konke noma enezinga eliphezulu, ithangi ligcina izimo ze-anaerobic, ukuxuba nokushisa ukuze amagciwane e-methanogenic aguqule i-feedstock ibe i-biogas ngokuqhubekayo.
Isitoreji (umsebenzi we-gas holder): Ukukhiqizwa kwe-biogas akukwazi ukufana nokusetshenziswa. Isitoreji — ama-membrane holders ahlanganisiwe ophahleni lwe-digester noma imikhumbi ehlukile — ihlukanisa kokubili, iqinisekisa ukondla kwe-boiler, CHP noma indawo yokuthuthukisa.
Ukuphepha nokulawula ingcindezi: Ophahleni lwamathangi, amadivayisi okukhulula nokuxhuma kwe-flare kulawula ukwehla nokukhuphuka kwengcindezi futhi kugcina igesi ingaphakathi komkhawulo wokuqhuma ngaphansi kwazo zonke izimo zokusebenza.
2. Izinto Eziyizinto Eziyinhloko Zobunjiniyela Zamathangi E-biogas Nezophahla
Igobolondo elingagqwali elingagqwali ku-H2S condensate: Amathangi e-GFS biogas ahlanganisa i-glass enamel engenamandla nensimbi ku-820–930°C — engathinteki yi-condensate ene-asidi noma ikhemistri ye-digester kusukela ku-pH 1–14, ngokungafani namagobolondo ahlanganisiwe lapho ama-linings awo enza amabhamuza endaweni yegesi.
Ukuqinisekiswa kokungangeni kwegesi: Amathangi e-GFS aboshwe nge-bolts anama-seams ane-gaskets kanye nophahla lwe-membrane ahlolwa ukuze kutholakale ukuvuza kwegesi; izakhiwo zokwakha zihambisana ne-AWWA D103, ISO 28765 kanye ne-EN 1090, zinikeza ubufakazi obubhaliwe kubanikazi bemishwalense nabalawuli.
Ukuphathwa kwegesi okuhlanganisiwe: Ama-digester esimanje e-GFS amukela ama-mixer afakwe maphakathi, imijikelezo yokushisisa, izinto zokubamba ezinamembane amabili phezu kophahla, nama-nozzle ezinsimbi njengephakethe elilodwa lobunjiniyela — kususa ubungozi bokungahambisani phakathi kwabahlinzeki begobolondo nophahla.

Imibuzo Ejwayelekile (FAQ)
UMBUZO 1: Liyini ithangi le-biogas?
Ithangi le-biogas umkhumbi ongangeni moya okhiqiza noma ogcina i-biogas enothile nge-methane (55–75% CH4) kusuka ekuboleni kwezinto eziphilayo ngaphandle komoya. Amagobolondo e-GFS amelana nokugqwala kwe-H2S condensate ku-pH 1–14 futhi aqinisekisiwe ukuthi awangeni moya ngokwe-ISO 28765 ne-EN 1090.
Q2: Uyini umehluko phakathi kwethangi legesi elivela emfucumfucwini (biogas tank) kanye nesitsha sokugaya imfucumfucu (biogas digester)?
Isitsha sokugaya (digester) yithangi lenqubo lapho imfucumfucu empeleni yehlukaniswa khona; "ithangi legesi elivela emfucumfucwini" yigama elibanzi elihlanganisa izitsha zokugaya kanye nemithangi ehlosiwe yokugcina. Empeleni, ama-GFS digesters ahlanganisa izinto zokugcina igesi ezingama-membrane ophahleni ukuze enze yomibili le misebenzi.
Q3: Kungani igesi elivela emfucumfucwini ligqwala amathangi?
Igesi eliluhlaza elivela emfucumfucwini liqukethe i-H2S kanye nomhwamuko wamanzi. Ezindongeni ezipholile, kuba ne-condensation eyenza i-sulfuric acid encibilikisiwe ehlasela izinto zokumboza eziphilayo kanye nokhonkolo. I-enamel engenayo i-inert efakwe ensimbini ngokushisisa (glass enamel fused to steel) ayihlaselwa yilokhu kuqwalala iminyaka engaphezu kwengu-30.
Q4: Kufanele isitshalo sibe nokugcina kwegesi elivela emfucumfucwini okungakanani?
Umkhuba ojwayelekile uyisuku elingu-0.5–1 lokukhiqiza njengesiqongo, kungaba ku-holder enamathembule amabili efakwe ophahleni noma ku-holder yegesi ehlukile — okwanele ukushelela iziqongo zokukhiqiza nokudlula ngesikhathi sokuma kwe-CHP noma ukuthuthukiswa.
