Ukwelashwa Kwemfucumfucu Yasekhishini & Ukubola Ngaphandle Komoya: Izixazululo Zobunjiniyela kanye Nesifundo Sasekesi Se-CSTR
Ukwanda okusheshayo kwabantu emadolobheni kanye nemikhuba yokudla eshintshayo kwenze ukwelashwa kukadoti wasekhishini kube inkinga enkulu yengqalasizinda yemvelo. Ukulahlwa ngempumelelo akugcini nje ngokunciphisa ukungcola okubi kwemvelo kodwa futhi kunikeza indlela yokukhiqizwa kwamandla avuselelekayo ngokusebenzisa ukubola okungenawo umoya. I-Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), umkhiqizi ohamba phambili e-Asia wamathangi okugcina anezikulufu, ihlinzeka ngengqalasizinda eyisisekelo yokubamba—amathangi e-Glass-Fused-to-Steel (GFS)—adingekayo ukuze kwenziwe le mibukiso eyinkimbinkimbi yokwelashwa kwamajubane ngokuphepha nangempumelelo.
1. Iphrofayili Eyinkimbinkimbi Yemfucumfucu Yasekhishini Kamasipala
E-China, inani lemifucumfucu yasekhishini kamasipala limangalisa. Ngokombiko we-Overview of the Status of Global Kitchen Waste Disposal owakhishwe yi-Tianjin University of Environmental Engineering, imifucumfucu yasekhishini ibalelwa ku-37% kuya ku-62% yenani eliphelele lemifucumfucu eqinile yasemadolobheni.
Le mifucumfucu, evelayo ekhishini lasekhaya, ezindaweni zokudlela, ezimakethe, kanye nezindawo zokucubungula ukudla, ibonisa izinselele ezihlukile zokuyelashwa ngenxa yokwakheka kwayo okudlulele:
● Ukuqukethwe Okuphezulu Kwamanzi Nokuqukethwe Okubolayo: Kuvumela ukubola okusheshayo nokubola okungalawulwa uma kungelashwanga.
● Amazinga Aphezulu Kawoyela Nenosawoti: Kwenza izindlela zokwelashwa ezijwayelekile zezinto eziphilayo zibe nzima futhi kwandisa kakhulu ukubola kweziqukathi ezijwayelekile.
Ngenkathi izindlela zendabuko zokulahla izinto zihlanganisa ukugibela, ukushisa, kanye ne-composting ye-aerobic, imboni iyashesha ukuguqukela ku-anaerobic digestion. Lobu buchwepheshe bukhulisa ukutholwa kwezinto eziphilayo, buguqule udoti onobungozi ube yi-biogas ewusizo kanye nomanyolo wezinto eziphilayo.
2. Ukuhlanganiswa Kobuchwepheshe: Inqubo ye-CSTR Anaerobic
Ukuphatha kahle umthwalo omkhulu wezinto eziphilayo ezivela emadoti asekhishini, inqubo ye-Continuous Stirred-Tank Reactor (CSTR) iyaziwa emhlabeni wonke njengenye yezindlela ezisebenza kahle kakhulu zokwelapha i-anaerobic.
Isebenza kanjani i-CSTR:
● Ukuxubeka Okuphelele: Inqubo ye-CSTR isebenzisa ukugxambukela komshini ukugcina izinto zokuvubela kanye namagciwane esesimweni esixubekile, esifanayo.
● Ukuphatha Okunamandla Aphezulu: Yakhelwe ngokukhethekile ukucubungula izinto ezingavuthiwe ezinokuqukethwe okuphezulu kwezinto ezingalungiswa, okuyenza ilungele udoti wokudla ogayiwe.
● Ukusebenza kahle kokuphendula: Ngokuvimbela izinto ukuthi zingahlukaniseki zibe izendlalelo, umshini wokugxambukela ugcwalisa ukuxhumana phakathi kwezinto eziphilayo namagciwane akhiqiza i-methane. Izinto eziphilayo ziqhubeka nokujikeleza ziye phansi kwesitsha sokuphendula, kancane kancane kuqedwe inqubo yokubola kwezinto eziphilayo.
Inqubo ye-CSTR idume ngokuba lula ekusebenzeni kwayo, izindleko eziphansi zokugcinwa, kanye nomkhiqizo omkhulu we-biogas.
3. Izitsha ze-GFS ze-Center Enamel: Indawo Yokugcina Ye-CSTR Efanelekayo
Ukufeza inqubo ye-CSTR kudinga isitsha sokuphendula esikwazi ukubekezelela ukugxambukela okungapheli komshini kanye nemvelo ye-biological enomthelela omkhulu, enesidididi. Izitsha ze-Glass-Fused-to-Steel (GFS) ze-Center Enamel ziyizinga lomkhakha wengqalasizinda yokubola kwe-anaerobic.
Zinokwethenjwa emazweni nasezifundeni ezingaphezu kwezi-100, izimbiza ze-GFS ezithuthukiswe yi-Center Enamel zinikeza izinzuzo ezihlukile zobunjiniyela ekwelapheni udoti wasekhishini:
● Ukumelana Nokugqwala Okungcono Kakhulu: I-vitreous enamel coating ihlanganiswe nensimbi ephezulu, idala umgoqo ongasebenzi ngokwemvelo ongamelana nokugqwala okubangelwa usawoti omningi kanye nokuba namandla e-acid okudla okubilayo.
● Ukwakhiwa Okusheshayo, Okungabizi Kancane: Umklamo we-modular bolted uvumela ukuhlanganiswa okusheshayo, kusuka phezulu kuye phansi, kunciphisa kakhulu izikhathi zephrojekthi kanye nezindleko zabasebenzi uma kuqhathaniswa nensimbi eyenziwe ngocingo noma ukhonkolo oluchithwe.
● Isikali Esingenamkhawulo: Umthamo wethangi ungakhuliswa kalula ngokungeza amanye amaringi amamodular ukuze uhlangabezane nezidingo zesikhathi esizayo zokucubungula udoti wedolobha.
4. Isifundo Sephrojekthi: Ukuphathwa Kodoti Wasemakhishini e-Beijing Fengtai
Ingqalasizinda ye-Center Enamel ihlolwe kabanzi emaphrojekthi omkhandlu wesikhathi eside, anamandla amakhulu. Isibonelo esihle kakhulu yiProjekthi Yokwelapha Udoti Wasekhishini yase-Beijing Fengtai.

Umphumela wePhrojekthi:
Ziqhubeke nokusebenza kusukela ngo-2016, lezi zinjini ezintathu ezinkulu ze-GFS zibonise ubuqotho obuphelele besakhiwo. Naphezu kwemvelo enolaka yangaphakathi ebalulekile ekugayweni kukadoti wasekhishini, izimbiza azibonisi zimpawu zokugqwala noma ukwehluleka kwe-coating, zithola ukubuyekezwa okuphezulu kubasebenzi bakamasipala kanye nabasayini be-EPC.
5. Isithembiso Sobunjiniyela Esizayo
I-Center Enamel izibophezele ekwakheni izixazululo zokugcina ezisezingeni eliphezulu, ezenziwe ngendlela efanele. Ngokuhlaziya ngokuphelele izici ezithile zodoti wasekhishini bendawo nezidingo zephrojekthi, sibambisana nezinkampani zobunjiniyela bemvelo ukusebenzisa izinhlaka ezifanele kakhulu zobuchwepheshe. Phambili, i-Center Enamel izoqhubeka nokutshala imali ku-R&D kanye nobuchwepheshe obusha bokugqoka i-enamel ukuze kwandiswe izinzuzo zezomnotho nezokusingabongile zamaphrojekthi omhlaba wonke wokuguqula udoti ube amandla.
