Indlela i-Fused Enamel Emelana Ngayo ne-Hydrogen Sulphide
I-Hydrogen sulphide iyisitha samathangi asemsebenzini we-anaerobic. I-Fused enamel ibhekana nayo hhayi ngesembozo 'esilwa' negesi, kodwa ngendawo okungenakwenzeka ukuthi igesi isabele nayo.
I-Fused enamel imelana ne-H2S ngoba ungqimba lwayo lwengilazi ye-vitreous alunazinto ezingasebenza namakhemikhali kuma-sulphide nama-asidi e-organic, akukho binder e-organic ephukayo njengoba kwenza i-epoxy noma upende.
Indlela yokusebenza ilula: i-vitreous enamel iyingilazi encibilikisiwe phezu kwensimbi ku-820-930 C. Njengoba iyisendlalelo esingaphili, esingenazimbotshana, nesingasebenzi, ayisebenzisani ngamakhemikhali ne-H2S noma izicubu ezinamandla ezizakha, ngakho-ke akukho lutho igesi engakuhlasela.
Izici Eziyisisekelo, Izingxenye Nezinhlobo
Indawo engasebenzi: Ingilazi ayinikezi isisekelo sokugqwala kwe-sulphide; insimbi engenalutho ngaphansi kwe-H2S igqwala ngamandla (ingcindezi ye-sulphide kanye nokugqwala okuyizimbotshana).
Akukho ukubola kwezinto eziphilayo: I-epoxy nopende kuncike kusibopho esiphilayo esingase sonakale, sichithe noma sivumele ukugqwala ngaphansi kwefilimu; i-enamel ayinaso leso sibopho.
Ayidluli: Isendlalelo esincibilikisiwe asinazimbotshana, sivimba ukuxhumana phakathi kwemvelo nensimbi.
Izinzile endaweni yegesi: Lapho i-H2S ihlangana namanzi ibe yiasidi ebuthakathaka, ingilazi ihlala ingathinteki.
Izinhlelo Zokusebenza Nezimo Zokusetshenziswa
Ama-anaerobic digester, amathangi e-sludge, ukwamukela i-septage, kanye nanoma yikuphi ukugcinwa kwe-liquor yezimboni noma kamasipala okune-sulphide.
Ukucatshangelwa Kwezobuchwepheshe
I-H2S lapho ikhona umswakama yakha i-sulphurous acid ebuthakathaka futhi, ngomoya-mpilo olinganiselwe, iholela ekugqwaleni kwe-sulphide yensimbi engenalutho, okuvame ukuba kubi kakhulu esikhaleni sangenhla. I-epoxy iyamelana nayo kuphela uma inamathele ngokuphelele; noma yikuphi ukungavali kahle kuvumela ukugqwala kwangaphansi kwefilimu ukuba kusakazeke. I-enamel encibilikisiwe isusa le ndlela yokwenzeka: ingilazi eqhubekayo, engasebenzi, engangeneki emanzini engenawo umgogodla wokunamathisela ongahluleka. Imikhawulo okufanele yaziwe: i-pH ephezulu kakhulu ehlangene nezinga lokushisa eliphezulu, futhi ikakhulukazi i-hydrofluoric acid noma i-fluoride ephezulu, kungahlasela ingilazi, ngakho-ke lezi zimo eziyingqayizivele kufanele zihlolwe; ebangeni elijwayelekile le-H2S/acid lokugaya kanye ne-sludge, i-enamel ingenye yezinketho ezimelana kakhulu.
Izinzuzo Nezithiyo
Izinzuzo:
Ukungasebenzi ngamakhemikhali, ukungangeneki kwamanzi kanye nokungabi khona kwesibopho sezinto eziphilayo kwenza i-enamel encibilikisiwe ibe ngenye yezindawo zamathangi ezimelana kakhulu ne-H2S ezitholakalayo, ikakhulukazi endaweni yegesi egqwalayo.
Imikhawulo:
I-enamel ayiyona into yonke: i-hydrofluoric acid ne-fluoride ephezulu kakhulu kuhlasela ingilazi, futhi inhlanganisela ye-pH ephezulu kakhulu/izinga lokushisa eliphezulu idinga ukuqinisekiswa. Njenganoma yiluphi ukumbozwa kwe-vitreous, umonakalo wokushayisana kufanele ulungiswe kusuka kumaphaneli esitokwe.
Ukuqhathanisa & Umhlahlandlela Wokukhetha
Into | Ukusabela kwe-H2S |
Insimbi engenalutho | Igqwalisa ngamandla (i-sulphide) |
I-Epoxy / upende | Ibamba uma kuphelele; iyahluleka ezindaweni ezingenalutho |
I-enamel encibilikisiwe (GFS) | Ayisebenzi, ayiphenduli |
Izinqubo Ezinhle Kakhulu & Indlela Yokukhetha
Cacisa i-enamel encibilikisiwe (ehlelwe ngezindawo) yokusebenza okune-H2S, qinisekisa ukuqhubeka ngokuhlolwa kwe-holiday ngephaneli ngayinye, futhi hlola izimo ezingavamile ezimbili (i-HF/fluoride, i-high-pH/high-temp eyedlulele) ngokumelene nokugeleza kwakho ngaphambi kokuqedela izinga.
I-enamel encibilikisiwe imelana ne-H2S ngoba ingilazi yayo e-vitreous ayisebenzi futhi ayidluli, ayinayo i-binder ephilayo engaqothuka njengoba kwenza i-epoxy. Ingenye yezinketho ezinhle kakhulu zokusebenza kwe-sulphide, ngaphandle kwe-fluoride kanye nezimo ezingavamile ze-high-pH/high-temperature eyedlulele.
Imibuzo Evame Ukubuzwa (FAQ)
Kungani i-H2S ingayihlaseli i-enamel?
Isendlalelo se-vitreous siyingilazi engaphili eboshwe ngensimbi; asisebenzi ngamakhemikhali ne-hydrogen sulphide noma i-asidi ebuthakathaka eyakha kuyo, futhi asinazimbobo, ngakho akukho sisekelo noma indlela yokugqwala kwe-sulphide.
Kungani i-enamel ingcono kune-epoxy ku-H2S?
I-epoxy incike ekuxhumaneni okuphelele kwezinto eziphilayo; noma yikuphi ukungavikeleki kahle kuvumela amanzi ukuthi angene ngaphansi kwefilimu futhi agqume insimbi. I-enamel ayinayo indawo yokunamathisela engahluleka, ngakho imelana ne-H2S ngisho nalapho isembozo singeqa.
I-H2S igqwala kakhulu kuphi emathangini?
Esikhaleni sekhanda nasezindaweni ezinamanzi, lapho igesi ye-H2S kanye nokujiya kwamanzi kwakha i-asidi ebuthakathaka futhi ukushintshashintsha kwamanzi nomoya kugxilisa ukuhlasela, kanye nendawo okufanele i-enamel ivikele kuyo ngezinga eliphezulu.
Ingabe i-enamel imelana nawo wonke amakhemikhali?
Cha. I-hydrofluoric acid ne-fluoride ephezulu kakhulu kuhlasela ingilazi, futhi i-pH ephezulu kakhulu ehambisana nezinga lokushisa eliphezulu idinga ukuqinisekiswa. Ekugayeni okujwayelekile kanye ne-sludge H2S/acid, imelana kakhulu.
Ingabe indawo yegesi ihlukile kunendawo engaphansi kwamanzi?
Yebo, futhi yindawo ebucayi: i-H2S ijiya lapho ibe yi-asidi. Khuphula izinga lokumboza esikhaleni segesi kanye nebhande lomugqa woketshezi esikhundleni sokuphatha ithangi lonke ngokufanayo.
