Ungakuvimbela kanjani ukugqwala kwe-sulfide emathangini?
I-sulfide corrosion iyisibulala-muntu esithulekayo samathangi endlane kanye nodaka. Izindawo ezingenawo umoya zivumela amabhaktheriya anciphisa i-sulfate ukuthi aguqule i-sulfate ibe yi-hydrogen sulfide, ekhuphukayo, ihlangane nomoya kanye ne-oxygen emgqeni wamanzi bese iba i-sulfuric acid - ngezinye izikhathi ngaphansi kwe-pH 2 - idla ukhonkolo nensimbi kusukela phezulu kuye phansi. Isixazululo akusilo iqhinga elilodwa kodwa uhlelo: vimba igesi ukuthi ingakheki noma ingafinyeleli phezulu, vikela indawo ehlaselwayo, futhi khetha izinto ezingayinaki i-acid encane evelayo. Phatha ingxenye eyodwa kuphela futhi ithangi lizohluleka.
IShijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) ibhekana nokugqwala kwe-sulfide emathangini amanzi angcolile nodaka ngesembozo se-vitreous-enamel engasebenzi, ukungena komoya ukunqamula umjikelezo we-H2S, kanye nokukhethwa kwezinto ngokucophelela emgqeni wamanzi, ngoba ukuhlasela kuyinkinga yekhemistri ngaphambi kokuba kube inkinga yokumboza.
1. Lapho Ukuhlasela Kuqala Khona
Iketanga liqala emdaka ongenamoya noma enhlabathini lapho amabhaktheriya e-sulfate-reducing ekhiqiza i-H2S. Igesi ihamba iye endaweni engaphezulu, ihlangane nomoya emgqeni wamanzi bese ixhuma ibe i-sulfuric acid enyuka edongeni ngenhla nje kuketshezi. Lelo bhande elincane - indawo egxilile yokugqwala - yilapho amathangi elahleka khona, ngoba i-acid igxilile futhi i-coating incane noma ayikho lapho. Ukwazi le ndawo kuyingxenye yempi.
· Indawo Engenamoya: Amabhaktheriya enza i-H2S.
· Khuphukela Emoyeni: Igesi ihlangana nomoya.
· I-Acid Yakheka: I-sulfuric acid emgqeni.
· Umugqa Wamanzi Mubi Kakhulu: Ibhande lokuhlasela eligxilile.
· Yazi Indawo: Ingxenye yempi.
2. Isivikelo Sesembozo Esingasebenzi
Isembozo se-vitreous-enamel (GFS) ingilazi ehlanganiswe nensimbi - ayisebenzi, ayinazimbotshana futhi imelana kakhulu ne-asidi, ngakho i-sulfuric acid eyakhekayo ayinakho okuningi engakuluma kukho. Ngokungafani nopende bemvelo abangathamba noma bagawulwe yi-asidi, i-enamel ihlala izinzile, yingakho iyisivikelo esijwayelekile semisebenzi yendle ebolayo nodaka. Isembozo asiyivimbi igesi, kodwa sinqabela i-asidi indawo yokudla.
· I-Enamel Yingilazi: Ayisebenzi, ayinazimbotshana.
· Imelana Ne-Asidi: Izinzile ku-sulfuric acid.
· Akuyona Imvelo: Ngeke ithambe noma igawulwe.
· Inqabela Indawo: I-asidi ayinakho okokudla.
· Ukuvikelwa Okujwayelekile: Kukhonzo lwamanzi angcolile/udaka.
3. Ukunqamula Umjikelezo we-H2S
Ngaphandle kwesembozo, umjikelezo wegesi uhlaselwa ngqo: ukungena komoya endaweni engenhla kunciphisa futhi kususe i-H2S ngaphambi kokuba ixide; ukufakwa kwe-biocide noma i-nitrate kungacindezela amagciwane anciphisa i-sulfate emthonjeni; ukugcina udaka lungangeni kwi-anaerobic kusukela ekuqaleni kunciphisa ukwakheka. Lezi zinyathelo zinciphisa ukuthi ingakanani i-asidi efinyelela odongeni, kwandise impilo yesembozo. Ukulawula ukugqwala kuyikhemistri kanye nokumboza, hhayi ukumboza kuphela.
· Ngenisa umoya: Susa i-H2S endaweni engenhla.
· I-Biocide/Nitrate: Cindezela amabhaktheriya.
· Gwema Indawo Engenamoya: Khawulela ukwakheka.
· I-Acid Encane: Yandisa impilo ye-lining.
· Ikhemistri Kanye Ne-Coating: Hhayi i-coating yodwa.

Isiqinisekiso Sobunjiniyela Nosekelo Lwephrojekthi
Wonke amathangi anikezwa yiShijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) aklanywa ngokuhambisana ne-AWWA D103-09 kanye ne-EN 1090 ngokuqinisekiswa kwe-finite element yomthwalo wegobongo, uphahla kanye nama-nozzle, ahlanganiswa ku-820-930°C ngaphansi kokulawulwa kwe-ISO 9001 ne-ISO 45001, ahlolwa nge-holiday test ku-1500 V kuyo yonke indawo engaphezulu, futhi ahlanganiswa ngamabhawodi e-Grade 8.8 kanye ne-sealant eqinisekiswe umkhiqizi. Ukulawulwa kokugqwala kunikezwa ngezicaciso ze-lining, isu lokungenisa umoya kanye ne-biocide elihambisana nomsebenzi, kanye nohlelo lokuhlola olugxile kubhande lwe-waterline, ukuze umnikazi alwe namakhemikhali kanye ne-coating ndawonye esikhundleni se-coating iyodwa.
Ukugqwala kwe-sulfide kunqotshwa njengohlelo, hhayi njenge-coating: ulwelwesi lwe-vitreous-enamel olungasebenzi lwenza ukuthi i-sulfuric acid ingabi nendawo yokudla, ukungena komoya kanye ne-biocide kuphula umjikelezo we-H2S ngaphambi kokuba i-asidi yakheke, futhi impahla efanele ibekwa ebangeni lamanzi lapho ukuhlasela kugxila khona. Udonga olungaphezulu nje kuketshezi yilona ndawo okufanele ivikelwe kakhulu, ngoba yilapho amathangi elahlekelwa khona.
Imibuzo Evame Ukubuzwa (FAQ)
Ingabe i-enamel ivimbela ukwakheka kwegesi le-H2S?
Cha - i-enamel ivikela indawo engaphezulu; ayivimbi amagciwane ekwenzeni igesi. Yingakho ukungena komoya kanye, lapho kufanele khona, ukufakwa kwe-biocide noma i-nitrate kuyingxenye yohlelo olufanayo. I-lining iyisivikelo lapho i-asidi ivela; ukuncishiswa komjikelezo kulawula ukuthi ingakanani i-asidi evelayo.
Kungani umugqa wamanzi uyindawo embi kakhulu?
Yilapho i-H2S ihlangana nomoya-mpilo futhi ibe i-sulfuric acid, egxilile odongeni endaweni encane. Futhi yilapho izinto zokumboza zizacile kakhulu uma zifakwe kabi. Ukuvikela nokuhlola leyo ndawo kuyisenzo esisodwa esinomthelela omkhulu kakhulu ekuphathweni kokugqwala kwe-sulfide.
Ingabe amathangi kakhonkolo nawo angathola lokhu?
Yebo - ukhonkolo uhlaselwa yile asidi efanayo futhi ungahlakazeka kabi. I-enamel-clad noma insimbi eboshwe kahle, enokungena komoya, iyisivikelo esivamile; ukhonkolo ngaphandle kwesivikelo emsebenzini we-H2S kuyindlela yokwehluleka eyaziwayo.
Ingabe isivikelo singenziwa ngendlela evumelana nethangi lami?
Yebo. Izinga lokufaka uphahla, izinga lokungena komoya, isu lesibulala-magciwane kanye nempahla yomugqa wamanzi kuhlelwa ngokulingana namakhemikhali akho odaka kanye nesimo sezulu, futhi kunikezwa ngohlelo lokuhlola olugxile ebhandeni lomugqa wamanzi.
