Ingabe I-Hydrogen Sulphide Ililimaza Kanjani Amathangi Okugcina?
I-hydrogen sulphide iyisizathu sokuthi amathangi endle ahluleke ukusuka phezulu kuye phansi. Oketshezini, amabhaktheriya anciphisa i-sulphate akhiqiza i-sulphide. Endaweni yegesi, iqembu elihlukile lamabhaktheriya liguguqukela ku-sulphuric acid odongeni olumanzi. I-asidi bese idla umqhele nengxenye engenhla - izakhi ezingabonwa muntu futhi ezingahlolwa muntu - kuyilapho ingaphezulu eligcwele amanzi libukeka liphelele.
Ukuqonda indlela yokusebenza kushintsha imininingwane. Uma umonakalo wenzeka ngaphezu kwezinga lamanzi futhi uvela ezintweni eziphilayo, khona-ke impendulo akulona udonga olujiyile; kuyindawo engenakuhlaselwa i-asidi, kanye nesembozo esigcina igesi ingaphumi emoyeni. I-Center Enamel icacisa i-glass-fused-to-steel ngalo sizathu emsebenzini wendle nokudaka.
1. I-Hydrogen Sulphide Ivela Kuphi?
Kusuka emsebenzini wamagciwane angadingi umoya-mpilo. Amagciwane anciphisa i-sulphate aguqule i-sulphate ne-sulphur ephilayo abe yi-hydrogen sulphide lapho kungekho khona umoya-mpilo - emanzini angcolile, ezintweni ezilahlwayo, emanzini acwiliswayo nasezitsheni zokugaya.
· Amagciwane Anciphisa i-Sulphate: Ezimweni ezingenamoya-mpilo la magciwane asebenzisa i-sulphate njengokwamukela ama-electron futhi akhiphe i-sulphide njengomkhiqizo ongemuhle.
· Izimo Ezikhulisa Ukukhiqizwa: Ukushisa okufudumele, umthwalo wezinto eziphilayo onamandla, ukugcinwa isikhathi eside nezindawo ezinganyakazi konke kukhulisa ukukhiqizwa kwe-sulphide.
· Lapho Igxila Khona: Izindawo zokungenisa, amathangi okulinganisa, amathangi okugcina udaka, izitsha zokugaya, ukugcinwa kwamanzi acwiliswayo nemigudu emide yokukhuphula amanzi angcolile.
· Futhi Iyingozi Yezokuphepha: I-hydrogen sulphide inobuthi emazingeni aphansi futhi iyingozi ngokushesha emazingeni aphezulu, yingakho ukuvalelwa nokungenisa umoya kulawulwa.
2. Iguquka Kanjani Ibe I-asidi?
Esikhaleni esingaphezulu kuketshezi. Igesi ye-hydrogen sulphide incibilika kulokho kumanzi okusemdludlungu ongaphezulu koketshezi, futhi amagciwane adonsa umoya-mpilo aguqulela i-sulphide abe i-sulphuric acid.
· Isinyathelo Sezinto Eziphilayo: Amagciwane adonsa umoya-mpilo, ikakhulukazi izinhlobo ze-Thiobacillus, aguqulela i-sulphide ibe i-sulphate, akhiqize i-asidi.
· Ukuthi Kungani Ngenhla Komugqa Wamanzi: Ukusabela kudinga igesi nomoya-mpilo, okutholakala kuphela ngenhla komugqa wamanzi - yingakho kubonakala iphethini yokugqwala emqoka emqulwini.
· Umthelela Kukhonkolo: I-asidi incibilisa usimende, yehlise i-pH yendawo futhi iveze insimbi, ebese igqwala futhi yande, yenze ukhonkolo uqhekeke ngokwengeziwe.
· Umthelela Ensimbini: I-asidi ne-sulphide kusheshisa ukugqwala okujwayelekile kanye nokugqwala okungathi siqhubeke, futhi i-sulphide ingakhuthaza ukuqhekeka ensimbini enamandla aphezulu.
· Amazinga Abonwayo: Emfuleni onamandla, ofudumele, onezinto ezinamandla, ukulahleka kukakhonkolo okungamamilimitha ambalwa ngonyaka kubhalwe kahle - okwanele ukubhoboza uphahla phakathi neminyaka eyishumi.
3. Ungayimisa Kanjani?
Izindlela ezintathu, okungcono ukuthi zisetshenziswe ndawonye: gcina igesi ingaphumi emoyeni, susa i-sulphide, futhi wenze indawo ingasebenzi.
· Izembozo Ezingangeni Moya Nokwelashwa: Uphahla lwe-aluminium oluvaliwe olunokuqoqwa kwegesi kuya ku-biofilter, i-scrubber noma uhlelo lwegesi lendawo kususa kokubili iphunga nokuchayeka.
· Ukungena Komoya Lapho Izembozo Zingasetshenziswa: Ukunciphiswa nokungena komoya okulawulwayo kugcina amazinga egesi engaphansi kwezinga lapho ukugqwala nengozi kuba khona.
· Indawo Engasebenzi Endaweni Yokuphaphazela Nendawo Engaphezulu: Ingilazi ehlanganiswe nensimbi ayithinteki asidi, ngakho umqhele nezingqimba ezingaphezulu zivikelwe impilo yonke yethangi.
· Ukulawula Umthombo: Ukufaka usawoti wensimbi ukuze kuncibilike isulfide, ukufaka i-nitrate ukuze kucindezelwe amagciwane anciphisa i-sulphate, nokunciphisa ukugcinwa emanzini angemi.
· Ukuhlola Okujwayelekile: Hlola ingaphansi lophahla nengxenye engenhla yegobolondo ngomjikelezo ochaziwe; ukugqwala komqhele akubonakali phansi futhi kuyingozi kakhulu uma sekuthuthukile.
Indawo Yethangi | Indlela Eyinhloko | Isinyathelo Sokuvikela |
Ngezansi komugqa wamanzi | I-sulphide encibilikile, ama-asidi e-organic, ama-chloride | Ukugqoka okungasebenzi; i-GFS imelana nakho kokuthathu |
Indawo yokuphaphazela emgqeni wamanzi | Ukushintshana kokumanzi nokomile, umoya-mpilo uyatholakala | Indawo eqinile, engenazimbotshana; akukho ukuhlukaniswa kokugqoka |
Isikhala esingaphezulu koketshezi | Ukuguqulwa kwe-biogenic kube i-sulphuric acid | Isembozo esingangeni moya kanye ne-GFS emqhele |
Ingaphansi lophahla | Ukuncibilika kwe-asidi, izinga lokugqwala elibi kakhulu | Ingilazi ehlanganisiwe noma ulwelwesi oluvaliwe; hlola njalo |
Umoya wangaphandle | Ukukhishwa kwephunga, ukuchayeka kokuphepha | Ukuqoqwa nokwelashwa kwegesi |
Ukuqinisekiswa kobunjiniyela nokusekelwa kwephrojekthi
Wonke ithangi elethwa yi-Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) lakhiwe ngokuqinisekisa i-AWWA D103-09 kanye ne-EN 1090 ngokuqinisekiswa kwe-finite element yomzimba, uphahla kanye nemithwalo ye-nozzle, lihlanganiswe ngezinga lokushisa elingu-820-930°C ngaphansi kokulawulwa kwe-ISO 9001 kanye ne-ISO 45001, lihlolwe nge-holiday test ku-1500 V kuyo yonke ingaphezulu elingamaphesenti ayikhulu, futhi lihlanganiswe ngamabhawudi e-Grade 8.8 kanye ne-sealant eqinisekiswe ngumkhiqizi. Amathangi endle kanye ne-sludge anikezwa ngophahla lwe-aluminium olungangeni moya (gas-tight), ama-nozzle okuqoqa igesi, izindawo zokungena ezivaliwe (sealed penetrations) kanye nengqimba yeglasi ehlanganisiwe evikela ingaphezulu eliphezulu kanye nezigaba ezingenhla lapho i-biogenic acid yakheka khona.
Imibuzo Ejwayelekile (FAQ)
Iphuma kuphi i-hydrogen sulphide emathangini?
Ivela kumabhaktheriya anciphisa i-sulphate asebenza ku-sulphate nesulphur ephilayo ngaphansi kwezimo ezingenawo umoya-mpilo. Ukugcwala kwayo kukhuphuka nokushisa, amandla ezinto eziphilayo, isikhathi sokugcinwa kwamanzi, nezindawo ezinganyakazi, ngakho izindawo zokungenisa amanzi, izindawo zokulinganisa, izindawo zokugcina udaka, nama-digester yizona ezithinteka kakhulu.
Kungani ukugqwala kubi kakhulu ngaphezu komugqa wamanzi?
Ngoba ukuguqula i-hydrogen sulphide ibe i-sulphuric acid kudinga umoya-mpilo. Lokho kwenzeka kuphela endaweni yegesi, emanzini amancane agqolozele odongeni nangaphansi kophahla - yingakho izindonga eziphezulu zehluleka ngaphambi kwezansi.
Ukugqwala kwe-biogenic kuhamba ngokushesha okungakanani?
Emfuleni wendle ofudumele, onamandla aphezulu, ukulahleka kwe-concrete yophahla ngamamilimitha ambalwa ngonyaka kubhalwe kahle. Lokho kwanele ukuveza insimbi futhi kuyonakalisa uphahla phakathi neminyaka eyishumi uma kungathathwa sinyathelo.
Uyikwenza kanjani ukumisa ukugqwala kwe-sulphide?
Hlanganisa izinyathelo: isembozo esingangeni moya esinokuqoqwa nokwelashwa kwegesi, ukungena komoya okulawulwayo lapho izembozo zingenzeki, indawo engasebenzi njengengilazi ehlanganiswe nensimbi ezindaweni ezingaphezulu nasezingeni loketshezi, ukulawula umthombo ngokusebenzisa usawoti we-iron noma i-nitrate, kanye nokuhlola okuvamile kwangaphansi kophahla.
