Uyini Uthangi Lokugcina I-Biogas?
Kwadalwa ngo 2024.03.21
Iyini i-Biogas Storage Tank?
Ithangi lokugcina i-biogas (elivame ukubizwa ngokuthi i-gas holder) iyisistimu ekhethekile yokugcina eklanyelwe ukugcina igesi ecebile nge-methane ekhiqizwa ngesikhathi sokubola kwe-organic waste ngaphandle komoya. Ngenxa yokuthi ukukhiqizwa kwe-biogas kuqhubeka kodwa ukusetshenziswa kwamandla kuvame ukushintshashintsha, la mathangi asebenza njengesihlanganisi esibalulekile, agcina igesi eyinsalela ngezikhathi zokuncipha kwesidingo futhi ayikhulule lapho amandla edingeka ekukhiqizeni ugesi, ekufudumezeni, noma ekuthuthukiseni ibe yi-biomethane.Ngokungafani namathangi ajwayelekile amanzi noma amakhemikhali, ukugcinwa kwe-biogas kumele kuphathe amagesi aguquguqukayo, avuthayo kuyilapho kumelana nemiphumela egqwala ye-hydrogen sulfide (H2S) evame ukutholakala ku-biogas eluhlaza.
Indima Yokugcina i-Biogas Ekuboleni Okungenamoya (Anaerobic Digestion)
I-Biogas ingxubevange eyakhiwe kakhulu yi-methane (CH4) ne-carbon dioxide (CO2). Ithangi lokugcina i-biogas linikeza umthamo odingekayo ukuze kulawulwe umfutho ngaphakathi kwesistimu yokubola okungenamoya. Ngaphandle kwesikhala sokugcina, ukushintshashintsha kokukhiqizwa kwegesi kungabangela ukukhuphuka komfutho okulimaza i-digester noma kuholele ekulahlekelweni okukhulu kwegesi ngezinhlelo zokushisa (flare systems).
Imisebenzi Eyinhloko:
1. Ukulawulwa Kwengcindezi: Igcina ingcindezi engaguquki emishinini esemanzini efana nezinjini ze-Combined Heat and Power (CHP).
2. Umthamo Wokugcina: Igcina igesi eyengeziwe ngesikhathi sokulungiswa noma ukuma kwemishini yokuguqula amandla.
3. Ukuphathwa Kwezokuphepha: Ivimbela ukuphuma kwe-methane—igesi enamandla ebamba ukushisa—emoyeni.
Izinhlobo Ezijwayelekile Zokugcina I-Biogas
Izinhlelo zokugcina i-biogas ziyahlukahluka ngokusekelwe esikalini somsebenzi, kusukela kumadigester amancane asemapulazini kuya ezimbonini ezinkulu.
Uhlobo Lokugcina | Indlela | Okufaneleka Kakhulu |
I-Double Membrane | Izingqimba ezimbili eziguquguqukayo zendwangu (ngaphakathi/ngaphandle) ezinomoya ophakathi. | Izitshalo Ze-AD Zezimboni/Zezentengiselwano |
Uphahla Olungaguquki | Uphahla oluqinile (ukhonkolo/insimbi) olunesikhala esincane segesi. | Ama-digester amancane anomthamo ophansi |
Isembozo Esintantayo | Isembozo esinwetshwayo esikhuphuka/sehla ngokuya ngevolumu yegesi. | Izikhungo zikamasipala eziphakathi nendawo |
Ibhhaluni Langaphandle | Ibhhaluni elizimele lendwangu elixhunywe ngamapayipi. | Amapulazi/Ukuhlelwa Kwamamojula |
Izinselelo Ezibalulekile Zobunjiniyela
Ukuklama ithangi lokugcina i-biogas kudinga ubunjiniyela obukhethekile ukuze kubhekwane nezakhiwo eziyingqayizivele zamakhemikhali nezomzimba zegesi.
1. Ukumelana Nokugqwala
I-biogas eluhlaza iqukethe umswakama ne-hydrogen sulfide, okudala izimo ezine-asidi. Amathangi kufanele akhiwe ngezinto ezimelana kakhulu nokugqwala njengezindwangu ezinamekwe ezikhethekile (PVC/PVDF), insimbi engagqwali, noma insimbi evitrified (ehlanganiswe nengilazi) ukuze kuvinjelwe ukonakala okusheshayo.
2. Ukuqina Kwegesi
I-Biogas iqukethe i-methane, eqhumayo uma ixutshwe nomoya. Izinhlelo zokugcina kufanele zisebenzise izinto eziphezulu, ezingangeni emoyeni kanye nezivalo ezingangeni moyini ukuze kuqinisekiswe ukugcinwa okungu-100% nokunciphisa ubungozi bokuvuza.
3. Ukuphepha nokukhulula Ingcindezi
Ithangi ngalinye lokugcina kufanele lihlanganise:
● Ama-Valve Okukhulula Ingcindezi (PRVs): Ukuvimbela ukulimala kwesakhiwo ngenxa yengcindezi eningi.
● Ama-Valve Okukhulula I-Vacuum: Ukuvimbela ithangi ekuweni lapho igesi ikhishwa noma amazinga okushisa ehla.
● Ukuvikelwa Kokuqhuma: Izinto ezingakhiqizi izinhlansi kanye nokufakwa phansi okufanele ukuze kuncishiswe ubungozi bokukhishwa kukagesi omile.
4. Ukuphathwa Kokujiya Kamanzi
Njengoba i-biogas iphola, umswakama uyajiya. Amasistimu kufanele afake izindawo zokukhipha amanzi (condensate traps) ukuze kususwe amanzi, kuvinjwe ukuqoqeka kwawo nokuvimba imigqa yegesi noma ukulimaza izinjini ezilandelayo.
Imibuzo Evame Ukubuzwa (FAQ)
Umbuzo: Kungani izimboni eziningi ze-biogas zisebenzisa amathangi ane-membrane ephindwe kabili?
A: Izinhlelo ezinolwelwesi olumbili zinikeza isixazululo sokugcina esingabizi kakhulu, esinomthamo omkhulu. Ulwelwesi olungaphandle lunikeza ukuvikelwa esimweni sezulu, kuyilapho ulwelwesi olungaphakathi lunwebeka futhi luncipha ngokuya ngevolumu yegesi. Ingcindezi yomoya esikhaleni esiphakathi kolwelwesi idala indawo yokugcina ezinzile futhi enengcindezi.
Q: Ungakwazi yini ukugcina i-biogas ethangini elijwayelekile le-propane noma lamanzi?
A: Cha. Amathangi ajwayelekile awenzelwe ukwakheka kwamakhemikhali athile e-biogas eluhlaza. I-biogas eluhlaza inamandla okugqwala, futhi amathangi ajwayelekile ngokuvamile awanakho ukuphathwa kwengcindezi, izivalo ezingangeni moya, kanye nezinto zokuphepha ezingavimbeli ukuqhuma ezidingekayo ekugcinweni kwe-methane enyakazayo.
Q: Wazi kanjani ukuthi ithangi ligcwele?
A: Amathangi esimanje okugcina i-biogas afakwe izinzwa ze-ultrasonic noma ze-radar. Lezi zinzwa zilandelela indawo yolwelwesi noma ingcindezi ngaphakathi ethangini, zinikeze idatha yesikhathi sangempela ohlelweni lokulawula lwendawo ukuze ziphathe ngokuzenzakalelayo ukugeleza kwegesi.
Ingabe unesithakazelo sokuhlola izidingo ezithile zomklamo wengqalasizinda enkulu ye-biogas?
