Kungani Amathangi Okugcina I-Biogas Adinga Ukwenziwa Ngokwezifiso?
Ukugcinwa kwe-biogas akukwazi ukusebenzisa ithangi elijwayelekile ngoba into egcinwayo akuwona amanzi - ingxube yegesi enengcindezi ephansi, eguquguqukayo, nebolayo okufanele igcinwe ngokuphephile futhi ibambezeleke uma ukukhiqizwa kungalingani. Ukwakheka kwegesi (i-methane, i-CO2, i-H2S, umswakama) kunquma izinto ezidingekayo kanye nokuvalwa; ingcindezi yokusebenza (ngokuvamile ama-mbar angu-5-30) inquma isakhiwo; futhi umthamo uvela ekulinganisweni kwegesi, hhayi usayizi wekhathalogi. Yenza ngokwezifiso lezi futhi ithangi liphephile; zishaye indiva futhi liyavuza, ligqwale noma lihluleke ukubambezela. Ukugcinwa kwe-biogas inkinga yokucaciswa, hhayi umkhiqizo oseshalofini.
I-Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) yenza ngokwezifiso amathangi okugcina i-biogas - ama-digester nezibambi zegesi - ngokuhambisana nokwakheka kwegesi, ingcindezi kanye nevolumu yephrojekthi ngayinye, ngoba igesi engaphansi kwengcindezi, eguquguqukayo, futhi egqwalayo ayikwazi ukugcinwa esitsheni esijwayelekile.
1. Ukwakheka Kwegesi Kuqondisa Izinto Ezisetshenziswayo
I-biogas ikakhulukazi i-methane (55-65 ekhulwini) ne-CO2, kodwa futhi ithwala umhwamuko wamanzi ne-hydrogen sulfide eyakha i-sulfuric acid emgqeni wamanzi. Leyo khemistri inquma into ezosetshenziswa: i-vitreous-enamel lining imelana ne-asidi nomswakama lapho insimbi ependiwe noma evamile ingabola khona. Izinga le-H2S ikakhulukazi linquma ukuthi indawo inobutha kangakanani, ngakho izinga le-lining likhethwa kusukela ekuhlaziyweni kwegesi, hhayi ukucatshangelwa.
· I-Methane 55-65%: Ingxenye ebalulekile.
· I-CO2 + Amanzi: Kukhona engxubeni.
· I-H2S Ikhona: Yakha i-asidi emgqeni wamanzi.
· I-Enamel Iyamelana: Ne-asidi nomswakama.
· Izinga Lisuka Ekuhlaziyweni: Alikacatshangelwa.
2. Ingcindezi Nomthamo Kubeka Ukuma
I-biogas igcinwa ngengcindezi ephansi, ngokuvamile engu-5-30 mbar, ngakho ithangi noma isigcini kufanele sakhelwe lowo mthwalo omnene kodwa ongapheli ngesivalo esithembekile - hhayi ingcindezi ephezulu yesitsha sengcindezi, futhi hhayi ukunganaki ingcindezi ngokuphelele. Umthamo ulandela ibhalansi yegesi: ukuthi ingakanani ekhiqizwayo, ukuthi iyahlukahluka kangakanani, nokuthi ingakanani ibhafa edingwa yinjini noma ibhoyila (ngokuvamile amahora angu-2-6 okukhipha okujwayelekile). Lezi zinombolo zilinganisa isigcini; umthamo ojwayelekile ungagxeka noma uchithe imali.
· 5-30 mbar: Isitoreji sengcindezi ephansi.
· Isivalo Esithembekile: Umthwalo omnene ongapheli.
· Umthamo Kusuka Kubhalansi: Ukuhlukahluka kokukhiqiza.
· Ibhafa 2-6 h: Iphakela ukusetshenziswa okungaguquki.
· Akuyona Indinganiso: Kulinganiswa ngephrojekthi.
3. Kungani Ithangi Elijwayelekile Lihluleka
Ithangi lamanzi elijwayelekile lakhelwe uketshezi, hhayi igesi: lingase lingabi naso isivalo esingavuzi igesi, isembozo esimelana nokugqwala se-H2S, kanye nomklamo wesakhiwo wengcindezi ephansi odingwa yisibambi. Faka i-biogas kulo bese uthola ukuvuza, ukugqwala okusheshayo emugqeni wamanzi, futhi akukho kubhafa kokugeleza okuguquguqukayo. Ukwenza ngokwezifiso akusona ukuhlobisa - umehluko phakathi kokugcina igesi ngokuphephile nokungayigcini nhlobo.
· Akunasivalo Segesi: Kuvuza igesi.
· I-Lining Engalungile: I-H2S iyayigqwala.
· Ayikho I-Buffer: Ukugeleza okuguquguqukayo akulawulwa.
· Ukwakhiwa Kwezinto Eziwuketshezi: Akukona kwegesi.
· Ukwenzelwa Ngendlela Ethile = Kuphephile: Umehluko ukhona ngempela.

Isiqinisekiso Sobunjiniyela Nosekelo Lwephrojekthi
Lelo thanki ngalinye elilethwa yiShijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) lakhiwe ngokuhambisana ne-AWWA D103-09 kanye ne-EN 1090 ngokuqinisekiswa kwe-finite element yomthwalo wegobolondo, uphahla kanye ne-nozzle, lihlanganiswe ku-820-930°C ngaphansi kokulawulwa kwe-ISO 9001 ne-ISO 45001, lihlolwe nge-holiday test ku-1500 V kulo lonke ubuso, futhi lihlanganiswe ngamabhawodi e-Grade 8.8 kanye ne-sealant eqinisekiswe umkhiqizi. Ithangi lilethwa lichazwe ngokuhambisana negesi yakho: izinga lokufaka uphawu olusuka ekuhlaziyweni kwegesi, isibambi esilinganiswe ngokulingana kwegesi ku-5-30 mbar, kanye ne-seal kanye nesakhiwo okufakazelwa ukuthi siyasebenza egesini elinengcindezi ephansi, ukuze isitoreji sibambe futhi sigcine i-biogas.
Amathangi okugcina i-biogas kufanele enziwe ngendlela eyenzelwe wona ngoba into egciniwe iyigesi enomfutho ophansi, eguquguqukayo, nebolayo, hhayi amanzi. Ukwakheka kwegesi (ikakhulukazi i-H2S) kunquma indawo yangaphakathi, umfutho ongu-5-30 mbar unquma isivalo nesakhiwo, kanti umthamo uvela ekulinganisweni kwegesi ukuze kubambe ukukhiqizwa uma kuqhathaniswa nokusetshenziswa okungaguquki. Ithangi elijwayelekile alinayo isivalo esingavuzi gesi, indawo yangaphakathi emelana ne-asidi kanye nomthamo ofanele - ngakho ukwenzelwa ngendlela ethile yikho okwenza ukugcinwa kuphephe kunokuba kube umhlobiso.
Imibuzo Evame Ukubuzwa (FAQ)
Ingabe i-digester ingasebenza futhi njengesigcini segesi?
Kwesinye isikhathi i-digester inendawo yegesi phezulu, kodwa isigcini esizinikele singcono ngoba sihlukanisa ukubamba kusuka ekugayeni futhi sigwema ukucindezela i-digester. Izitshalo eziningi ezithembekile ziyazihlukanisa; i-digester ihlala kumfutho wenqubo kanti isigcini sibamba okubambayo.
Ibalwa kanjani ivolumu yegesi?
Kusuka kubhalansi yegesi: izinga lokukhiqiza elijwayelekile, ukuguquguquka kwalo, kanye ne-buffer edingekayo ukumboza amahora angu-2-6 okukhipha okujwayelekile (noma iphethini yokusetshenziswa). Kuyinombolo ebalwayo evela kuma-feedstock akho nokusetshenziswa kwamandla, hhayi usayizi wethangi ojwayelekile.
Ingabe umswakama egasini ubalulekile ethangini?
Yebo - amanzi ayajiya futhi, ne-H2S, akha i-asidi emgqeni wamanzi, indawo evamile yokuhlaselwa. I-lining ne-ventilation kucaciswa ukubhekana nalokho, okungesinye isizathu sokuthi ithangi lenziwe ngokwezifiso kunokuba lijwayelekile.
Ingabe ithangi le-biogas lingenzelwa ngokwezifiso embonini yami?
Yebo. Izinga le-lining, usayizi we-holder, i-pressure seal kanye nesakhiwo kuhlelwa ngokwakheka kwegasi lakho kanye nebhalansi yegasi, kulethwa nencazelo ngesikhathi sokunikezwa.
