Amathangi Aphahla Intantayo: Umhlahlandlela Wezobunjiniyela Nokulawulwa Kokukhishwa
I-Floating Roof Tank iyisiqukathi esikhethekile sokugcina uketshezi esenzelwe ukuqeda isikhala somoya phakathi komkhiqizo oketshezi kanye nophahla lwe-tanki. Ngokuhlala ngqo phezu komhlaba woketshezi, uphahla luyenyuka futhi lwehle ngokuphakama komkhiqizo, luvimbele ngempumelelo ukubilisa kwama-organic compounds avolatile (ama-VOC). Lobu buchwepheshe bubalulekile ekugcinweni kukaphethiloli ongahluziwe, uphethiloli, namanye ama-hydrocarbon avolatile, njengokuvikela okuyinhloko ngokumelene nokulahleka komkhiqizo, ukungcola komoya, nezingozi zomlilo.
1. Ingqikithi Yobunjiniyela: Ukuqeda Isikhala Somusi
Ethangini elijwayelekile eliphahla liqinile, "ukulahleka kokuphefumula" kwenzeka lapho izinguquko zokushisa zibangela ukuthi isikhala somusi sande futhi sinciphe, siphoqelele ama-hydrocarbon ngaphandle ngemiphefumulo ethangi. Amathangi aphahla intantayo axazulula lokhu ngokugcina ideski lihlale lithintana nolwazi.
● Ukwakhiwa: Uphahla (kungaba umklamo wensimbi, we-pontoon, noma we-sandwich-panel) lwakhiwe ukuze luntante kalula phezu kobuso bolwazi.
● Uhlelo Lokubopha: Umgodi phakathi konqenqema lwophahla nodonga lwethangi uboshwe ngezibopho zangaphambili nezesibili, ezibalulekile ekuvimbela ukuvuza komusi.
2. Izinhlobo Zophahla Oluntantayo
Onjiniyela bavame ukuhlukanisa uphahla oluntantayo ezinhlotsheni ezimbili eziyinhloko ngokusekelwe endaweni yokufakwa kwazo.
A. Uphahla Oluhlale Ngaphakathi Oluntantayo (IFR)
Lezi zifakwa ngaphakathi ethangini eliphinde libe nophahla olungaphandle oluqinile (njengodome we-aluminium noma uphahla lwe-cone).
● Isicelo: Isetshenziselwa ukulawula isimo sezulu, ukuvimbela ukuqoqwa kwezulu/iqhwa, nokugcinwa kwesibili ezindaweni eziqinile zekhwalithi yomoya.
● Inzuzo: Ivikelwe ezintweni, kunciphisa ukuguga nokudabuka esigodini sesiphrofoma kanye nohlelo lokubopha.
B. Isiphrofoma Sangaphandle Esintantayo (EFR)
Lezi zihlala phezu kwethangi ngaphandle kophahla oluqinile ngaphezulu kwazo.
● Isicelo: Ngokuvamile isetshenziselwa amathangi anobubanzi obukhulu ezindaweni ezimnene.
● Imfuneko: Kufanele ifake uhlelo lokudonsa amanzi (ngokuvamile ipayipi elihlangene noma inhlanganisela ethambile) ukususa amanzi emvula aqoqekayo esigodini sesiphrofoma ukuze kuvinjwe isiphrofoma ukuthi singacwilisi.
3. I-Matrix Eqhathanisayo: IFR vs. EFR
Lapho ukhetha umklamo wethangi, abaphathi bezindawo kufanele balinganise ukuchayeka kwemvelo ngokumelene nezindleko zemali kanye nokugcinwa.
Isici | Uphahla Oluhlale Ngaphakathi Oluntantayo (IFR) | Uphahla Oluzingezayo Ngaphandle (EFR) |
Ukuvezwa Kwemvelo | Kuncane (Kuvikelwe uphahla oluqinile) | Kuningi (Kuvezwe ngqo) |
Ukuphathwa Kwemvula/Iqhwa | Akudingekile | Kubalulekile (Kudingeka uhlelo lokudonsa amanzi) |
Ukugcinwa | Kuncane (Imfucumfucu encane) | Kuningi (Kudinga ukuhlanza ideski) |
Izindleko Zokwakha | Kuningi (Kudinga uphahla oluqinile) | Kuncane (Akukho uphahla oluqinile) |
Kungcono Kakhulu Ku | Izindawo ezinesimo sezulu esibi kakhulu / Ukuboshwa kwe-VOC | Ububanzi obukhulu / Izindawo zesimo sezulu esithambile |
4. Ukuhambisana Nokuphepha Nemithetho
Umklamo nokusebenza kwamathangi aphuhlayo kulawulwa yimigomo yomhlaba wonke yobunjiniyela, ikakhulukazi i-API 650 (Isijobelelo C & H). Izinto ezibalulekile zokuphepha zihlanganisa:
● Ubuqotho besondo lokubopha: Isondo lokubopha yilona elivame ukwehluleka. Izinhlelo zesimanje ezimbili zokubopha (isihlangu somshini esiyinhloko + isibopho somswakama esesibili) zithathwa njenge-"Best Available Control Technology" (BACT) yokunciphisa ukukhishwa kwe-VOC.
● Izinto zokuvimbela ukujikeleza: Lezi ziqinisekisa ukuthi uphahla oluncibilikayo luhlala luhambisana nodonga lwethangi, luvimbela izibopho ukuthi zingabambeki noma zingadabuki ngesikhathi sokuhamba.
● Ukucindezela umusi: Ngokukhipha indawo enomusi ovutha kalula, la mathangi anciphisa kakhulu ingozi yokuqhuma kwangaphakathi uma kuqhathaniswa namathangi anophahla oluqinile agcina umkhiqizo ofanayo.
5. Imibuzo Evame Ukubuzwa (FAQ)
Q: Ingabe ithangi elinophahla oluqinile lingaguqulwa libe yithangi elinophahla oluncibilikayo lwangaphakathi?
A: Yebo. Le yindlela ejwayelekile yokulungisa kabusha izindawo ezifuna ukuthobela imithetho eqinile yezemvelo noma ukunciphisa ukulahleka komkhiqizo ngaphandle kokwakha kabusha yonke ingxenye yethangi.
Q: Yisiphi isizathu esivame kakhulu sokuthi uphahla oluntantayo lugcwale?
A: Imbangela ejwayelekile ukwehluleka kohlelo lokudonsa amanzi (kuma-EFR) noma ukuvuza kwamaphampu okwenza kube nokuntanta. Amashejuli okuhlola afanele kanye nokugcinwa kwezimpawu kubalulekile ukuvimbela lezi zinkinga.
Q: Ingabe uphahla oluntantayo luyadingeka ekugcinweni kukadizili?
A: Kuncike kwi-flash point ethile kanye nezimfuneko zomthetho zesifunda. Noma kungafani negesi elivutha kalula njenge-gasoline, uphahla oluntantayo luvame ukusetshenziselwa ukugcinwa kukadizili okukhulu ukuvimbela ukubola nokugcina ubumsulwa bomkhiqizo.
Amathangi anophahla oluntantayo ahlala eyisixazululo esiqinisekile sobunjiniyela sokugcinwa okuphephile nokusebenzayo kwezinto eziyisidina. Ngokukhetha phakathi kwezinhlobo zangaphakathi noma zangaphandle ngokusekelwe ezidingweni zemvelo kanye nezokusebenza, izindawo zingakwazi ukukhulisa ivolumu yomkhiqizo, ukuqinisekisa ukuthobela imithetho, futhi kunciphise kakhulu umthelela emoyeni.
Ingabe usukuhlele ukuklama isikhungo esisha sokugcina, noma ingabe ufuna ukwenza ukuhlaziywa kwezindleko-nzuzo ekulungiseni izakhiwo zakho ezikhona ezineziphrofoma eziqinile ngobuchwepheshe besiphrofoma esintantayo?
