Kwadalwa ngo Ngokwamukisa
Kungani Ithangi Lensimbi Elinengilazi Isetshenziselwa Ukugaywa Kodaka?
Izitsha zokugaya udaka zihlanganisa zonke izindlela zokugqwala umkhumbi wokugcina ongabhekana nazo, futhi zengeza ukushisa. I-sulphide evela oketshezini, i-ammonia ekhishwa ngesikhathi sokubola kwamaprotheni, ama-acid amafutha aguquguqukayo noma nini lapho ibhayoloji icindezelwa, i-grit ekhuhla phansi, i-foam ne-scum ebusweni, kanye negobolondo eligcinwa ku-35 kuya ku-38 degrees Celsius amashumi eminyaka. Isembozo esisinda kwezintathu zalezo bese sihluleka kwesine, akusona isembozo, uhlelo lokulungisa.
Ingilazi isetshenziswa ngoba ayinazinto eziyihlaselayo kulo lonke uhlu ngesikhathi esisodwa, futhi ngoba yenza okunye okubalulekile ekusebenzeni: ihlala ibushelelezi. I-scum nezingqimba ze-rag zinamathela kancane kakhulu engilazini evuthiwe, ngakho umthamo wokusebenza kanye nezindawo zokudlulisa ukushisa ziyasinda phakathi kokuhlanza.
1. Yini Ehlasela Ingaphakathi Lomgayi Wodaka?
Izindlela ezinhlanu, ezisebenza emazingeni ahlukene ethangini futhi akuvamisile ukuthi zonke zibhalwe encazelweni efanayo.
· I-Hydrogen Sulphide: Ikhiqizwa ngokuqhubekayo oketshezini futhi ishintshwe ibe yi-sulphuric acid endaweni yegesi, ihlasela isiqongo kanye nezingqimba eziphezulu.
· I-Ammonia: Ikhishwa ngesikhathi sokubola kwamaprotheni futhi inamandla kakhulu emazingeni okushisa e-thermophilic, ikakhulukazi kwamanye ama-polymer kanye nezingxube zethusi.
· Ama-Volatile Fatty Acids: Aqoqana noma nini lapho umthwalo wemvelo noma izinga lokushisa kuphazamisa inqubo, kwehlisa i-pH futhi kuhlasela izindawo ezisengozini.
· I-Grit kanye ne-Abrasion: Isihlabathi kanye ne-grit kudaka kukhuhla phansi kanye negobolondo elingezansi, futhi kugqwalisa izinto zokumboza ezithambile kanye nezingaphezulu zikakhonkolo.
· Ukushintshashintsha Kokushisa: Ukushisa kanye nanoma yikuphi ukuguquguquka kwezinga lokushisa okuhluphayo kucindezela isibopho phakathi kokumboza kanye ne-substrate, okuyindawo lapho amafilimu anamathele eqala ukwehluleka khona.
2. Kungani Ingilazi Iphila Kukho Konke Lokhu?
Ngenxa yokuthi ingaphezulu liyinethiwekhi yengilazi engaphili ehlanganiswe nensimbi ku-820-930 degrees Celsius - akukho binder kulo okungahlaselwa yinoma yikuphi kwalokhu kusebenza kwamakhemikhali.
· Ayinazwelo ku-Sulphide ne-Acid: Akukho hydrogen sulphide noma i-sulphuric acid eyakhiwayo okuthinta ingilazi ehlanganisiwe, yingakho umqhele nezingqimba ezingaphezulu zihlala ziqinile.
· Kuzinzile nge-Ammonia: I-Ammonia emazingeni okushisa e-digester ayinakiwe inethiwekhi yengilazi, ngokungafani nezinye izinto zokufaka ezingama-polymeric kanye nezingxenye zensimbi.
· Ukuzinza Kokushisa: Ukufakwa okwenziwe emazingeni okushisa esithandazini akuthinteki neze amazinga okushisa okusebenza e-digester noma ukuhlanza emazingeni aphezulu okushisa.
· Ukumelana Nokuhuzuka: Cishe ku-6.0 esikalini se-Mohs, okumelana nokuhuzuka kwezinsimbi okugqoka amafilimu e-polymer kanye nokhonkolo.
· Amandla Aphansi Ebusweni: I-scum, igwebu kanye nezingqimba zama-rag zinamathela kancane engilazini evuthiwe, ngakho umthamo omncane ulahleka ezingxenyeni eziqinile futhi ukuhlanza kuyashesha.
3. Kusho Ukuthini Empilweni Yonke?
Ukufakwa kwe-digester okungagugi noma kungasabeli kushintsha umthwalo wokulungisa usuka ekufakweni uye ezintweni zomshini, okulula kakhulu futhi kushibhe kakhulu ukuzilungisa.
· Ukufakwa Akusiyo Into Yokulungisa: Ukuhlola nokulungisa kugxila kuma-mixers, ama-seals, izinto zokushisa kanye nemishini yegesi hhayi ekufakweni.
· Akukho Mjikelezo Wokumboza Kabusha: Ngokungafani nezinto zokumboza ze-polymer, indawo yengilazi encibilikisiwe ayinaso isikhathi esichaziwe sokumboza kabusha, okususa ukuphazamiseka okukhulu okuhleliwe empilweni ye-digester.
· Umthamo Wokusebenza Uyalondolozwa: Ukunamathela okuncane kwendle kanye nokungabi nasikali sokugqwala kusho ukuthi umthamo osebenzayo uhlala useduze nomklamo.
· Ukulimala Okulungisekayo: Ukulimala kwemishini kulungiswa ngohlelo olugunyaziwe futhi kuhlolwe kabusha, kubuyiselwe izinga lokuqala esikhundleni sokulungisa nje.
· Impilo Ende Yempahla: Iminyaka engamashumi amathathu nangaphezulu iyisikhathi sokuhlela esingokoqobo, esihambisana nesikhathi sokuxhaswa ngezimali kwempahla yodaka kamasipala eminingi.
Indlela Yokuhlasela | Umthelela Ezintweni Ezinye | Ukusabela Kwe-Glass Lining |

Isiqinisekiso Sobunjiniyela Nokusekelwa Kwephrojekthi
Wonke amathangi alethwa yi-Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) aklanywa ngokuhambisana ne-AWWA D103-09 kanye ne-EN 1090 ngokuqinisekiswa kwe-finite element yomthwalo wegobolondo, uphahla kanye ne-nozzle, ahlanganiswe ku-820-930°C ngaphansi kokulawulwa kwe-ISO 9001 ne-ISO 45001, ahlolwe nge-holiday test ku-1500 V kuyo yonke indawo, futhi ahlanganiswe ngamabhawodi e-Grade 8.8 kanye ne-sealant eqinisekiswe umkhiqizi. Ama-digester ane-glass lining anikezwa ngophahla oluvaliwe kanye nama-gas dome, ukushisa kanye nokufaka insulation, ukuxuba, ukuphathwa kwegesi kanye nohlelo lokulungisa i-coating olugunyaziwe olugcinwa kukhithi yezinto zasesizeni.
"I-disho le-digester kufanele likwazi ukumelana ne-sulphide, i-ammonia, i-asidi, i-grit kanye nokushisa ngasikhathi sinye. Ingilazi iyona kuphela indawo yokumboza evamile engaxoxisani nanoma yikuphi kulokhu."
Imibuzo Evame Ukubuzwa (FAQ)
Yini ehlasela ingaphakathi le-sludge digester?
I-hydrogen sulphide kanye ne-asidi eyakha endaweni yegesi, i-ammonia ekhishwa ngesikhathi sokubola kwamaprotheni, ama-volatile fatty acids ngesikhathi sokuphazamiseka kwenqubo, i-grit nesihlabathi esikhuhla phansi, kanye nokushintsha kokushisa okuvela ekushisiseni.
Ingabe i-ammonia ilimaza izinto zokumboza ze-digester?
Ingalimaza ezinye izinto zokumboza ezenziwe nge-polymer kanye nezingxenye zensimbi, ikakhulukazi emazingeni okushisa e-thermophilic. Ubuso bengilazi encibilikisiwe abuthinteki ku-ammonia kunoma yiliphi izinga lokushisa lokusebenza le-digester.
Kungani ukunamathela kwe-scum kubalulekile?
Izendlalelo ze-scum ne-rag zinciphungula umthamo wokusebenza osebenzayo, zivimba ukushisa ukuthi kungafinyeleli okoketshezini, zivimbe ukukhishwa kwegesi futhi ekugcineni ziphoqelele ukuvalwa komsebenzi ukuze kuhlanzwe. Ingaphezulu lengilazi elibushelelezi limelana nokunamathela, ngakho umthamo omningi womklamo uhlala usetshenziseka isikhathi eside.
Ingabe i-digester ene-glass lining ihlala isikhathi esingakanani?
Iminyaka engamashumi amathathu nangaphezulu iyisikhathi sokuhlela esingokoqobo. I-coating ayinayo i-organic binder engabola, ngakho ukunakekelwa kugxila kuma-mixers, ama-seals, ukushisa kanye nemishini yegesi kunokuba kugxile ku-lining.
