Ukusetshenziswa kwejeneretha yesitimu embonini ye-oleochemical kuyanda kakhulu, futhi sekudonse ukunakwa okwengeziwe kumakhasimende. Ngokwezidingo ezihlukene zenqubo yokukhiqiza, amajeneretha ahlukene omusi angaklanywa. Njengamanje, ukukhiqizwa kwamajeneretha e-steam embonini ye-petroleum kuye kwaba yisiqondiso esibalulekile sokuthuthukiswa kwemishini yokukhiqiza embonini. Enqubweni yokukhiqiza, isitimu esinomswakamo othile siyadingeka njengamanzi okupholisa, futhi izinga lokushisa eliphezulu kanye nomusi wokucindezela okuphezulu kwakheka ngokusebenzisa ukuhwamuka. Ngakho-ke ungafinyelela kanjani izinga lokushisa eliphakeme kanye nemishini ye-steam ephezulu ngaphandle kokungcolisa futhi uqinisekise ukusebenza okuzinzile kwemishini ye-steam
1. Izinga lokushisa lokuhwamuka liphakathi kuka-130-150°C
Ukuthi ijeneretha yesitimu somfutho ophezulu inganikeza izinga lokushisa eliphezulu nokucindezela kuyisihluthulelo sokuqinisekisa ikhwalithi yomkhiqizo nokukhiqiza okuzinzile. Amajeneretha e-Steam angahlukaniswa abe uhlobo olulodwa lodonga, uhlobo oluhlanganisiwe nezinye izinhlobo. Imikhiqizo ngokuvamile ikhetha izinhlobo ezahlukene zamajeneretha omusi ngokuya ngenqubo yokukhiqiza. Ijeneretha yesitimu kufanele ikwazi ukuhlangabezana nezidingo zenqubo. Ukusetshenziswa kanye nohlobo lwesitimu kungakhethwa ngokunengqondo ngokuvumelana nezidingo zezimboni ezahlukene. Ingasetshenziswa ngokuqondile ekukhiqizeni i-petroleum, imboni yamakhemikhali nezinye izimboni, kodwa uma ufuna ukuba nombono omuhle we-steam, awukwazi ukukuziba ukusetshenziswa kwemishini.
2. Ingcindezi iphakathi kuka-1.2-2.5MPa
Ngemva kokuba amafutha edlula ejeneretha ye-steam, amafutha anamanzi angu-1% -2% angashesha abe yizinga lokushisa eliphezulu elingenantuthu kanye nowoyela wengcindezi ephezulu. Ngemva kokushisa okuphezulu kanye nenqubo yokucindezela okukhulu, inani elikhulu lokushisa eliphezulu nokucindezela okukhulu, umusi ongenantuthu nongenambitheki ukhiqizwa. Ijeneretha yesitimu ngokuyinhloko iyisici esibalulekile sokusebenzisa i-boiler steam generator ukuze kufezeke umsebenzi wemishini. Ngakho-ke, abakhiqizi bazosebenzisa imikhiqizo ekhiqizwe amajeneretha e-steam ohlelweni lokukhiqiza ukuze bahlinzekele izimboni ze-petroleum kanye namakhemikhali. Lokhu kungenxa yokuthi umkhiqizo ungenza imikhiqizo kawoyela namafutha ibe nenhlanzeko futhi kulula ukuyigcina.
3. Uma ingcindezi ingaphansi kuka-2.5MPa, ngeke kube khona ingozi yokuqhuma kweshubhu kubhayela
Ekukhiqizeni uwoyela, kunezinqubo eziningi ezifana nokuhlukaniswa, ukuchithwa kombala, ukuhlunga, ukugxila, njll, futhi le nqubo inezidingo eziphezulu ze-steam. Izinto zendabuko zokuhwamuka zingafinyelela kuphela ukuhwamuka kwamanzi ukuze kukhiqizwe isitimu ngaphansi komswakamo othile. Lezi zinqubo zidinga ukusetshenziswa kwe-steam. Uma izinga lokushisa le-steam lingahlangabezani nezidingo ezithile, asikho isiqinisekiso sokuthi i-boiler ngeke iqhume. Ukusetshenziswa kwamajeneretha omusi ekukhiqizeni i-petroleum kungahlangabezana nezidingo zokukhiqizwa kwe-petroleum. Kodwa-ke, ijeneretha yesitimu nayo ihlangabezane nezinkinga ezithile phakathi nokusetshenziswa kwayo, ikakhulukazi ngenxa yokonakala ohlelweni lokujikeleza kwamanzi esitimu kanye nesimiso samanzi ahwamukayo, okungaholela kalula ekushiseni okungazinzile kwebhayela, ukuqhuma kweshubhu kanye nokwehluleka kwebhoyili. Kukhona futhi amanye amabhizinisi asebenzisa amajeneretha e-steam ukukhiqiza isitimu esinengcindezi ephezulu, engeyinhle ngekhwalithi, emoshayo, futhi engasebenzi kahle. Njengamanje, amajeneretha omusi wokubuyisa uwoyela asetshenziswa kakhulu emkhakheni wemboni ye-petrochemical, futhi imikhakha yawo yokusetshenziswa nawo iya ngokuya iba banzi embonini ye-petroleum.
4. Isici sokuphepha sesistimu ephezulu
Emshinini wokushisa ophezulu kanye nomfutho ophezulu we-steam, isimiso sokusebenza se-steam generator ukusebenzisa ukushisa okukhiqizwe ama-molecule wamanzi kanye ne-steam ukufingqa umhwamuko ube amaconsi amanzi noma ukujiya umhwamuko ube amanzi noma ezinye izinto. Umhwamuko ungafakwa i-oxidized ngomoya ukuze ukhiqize amagesi avuthayo njenge-hydrogen ne-carbon monoxide. Ngale ndlela, ingasebenzisa umhwamuko wamanzi ukuze imunce inani elikhulu lokushisa ukuze ihwamulise amanzi ukuze ikhiqize umhwamuko wamanzi (umhwamuko wamanzi). Ivelu ye-calorific yalesi sitimu esinezinga eliphezulu lokushisa nomfutho ophezulu siphezulu njengo-800°C-1200°C, okuyizikhathi eziphindwe ka-4-5 kune-metal distillation, ngakho-ke singagwema ngempumelelo izingozi zokuphepha ezingaba khona zemishini noma izinhlelo, futhi uhlelo lunesici esiphezulu sokuphepha! Ngakho-ke i-steam generator iyithuluzi eliphephile uma kuqhathaniswa.
