Uyilo kunye nokwakhiwa kwezithando zokuqhekeka
Isishwankathelo:
Isithando somlilo esiqhekekayo sisixhobo esibalulekileyo kwimveliso enkulu ye-ethylene, esisebenzisa ii-hydrocarbons zegesi (i-ethane, i-propane, i-butane) kunye nee-hydrocarbons ezingamanzi (ioyile ekhanyayo, idizili, idizili ye-vacuum) njengezinto eziluhlaza.i-peratureye750-900, ngabaiqhekeke ngobushushu ukuvelisa izinto ezikrwada ze-petrochemical,ezifana ne-ethane, i-propane, i-butadiene, i-acetylene kunye ne-aromatics. Kukho iintlobo ezimbini ze-isithando somlilo esiqhekekayo: iisithando somlilo esikhaphukhaphu sedizili esilula kunyeiisithando somlilo esiqhekekayo se-ethane, zombini eziluhlobo oluthe nkqo lwezitofu zokufudumeza. Isakhiwo sesithando ngokubanzi sinezinto ezimbini: inxalenye ephezulu licandelo le-convection, kwaye inxalenye esezantsi licandelo le-radiant. Ityhubhu yesithando esithe nkqo kwicandelo le-radiant yinxalenye yempendulo yokufudumeza kwe-hydrocarbon yesixhobo sokuqhekeka. Ubushushu besithando yi-1260°C, kwaye iindonga kumacala omabini nasezantsi zixhotyiswe ngezitshisi zeoyile negesi. Ngenxa yeempawu ezingentla zesithando sokuqhekeka, i-fiber lining isetyenziswa kuphela kwiindonga nakumphezulu wegumbi le-radiant.
Ukuchonga izinto zokubopha ilayini:
Ukuqwalasela ukuphakamaubushushu besithando (ngesiqhelo malunga ne-1260℃)kwayeumoya obuthathaka wokunciphisangaphakathiisithando somlilo esiqhekekileyonjengoiminyaka yethu yamava oyilo nokwakha kunyeinyani yokubainani elikhulu lokuqhekekaIzitshisi ze-furnace zihlala zisasazwa kwisithando somlilo ezantsi kwaye kumacala omabini odonga, izinto zokwambathisa ze-furnace eqhekekayo zichongiwe ukuba ziquka ulwelo lwezitena ezikhazimlayo oluyimitha ezi-4 ubude. Iindawo eziseleyo zisebenzisa izinto zefayibha ezine-zirconium njengezinto ezishushu kumphezulu we-lining, ngelixa izinto zokwambathisa ezingasemva zisebenzisa iingubo zefayibha ze-ceramic ze-CCEWOOL high aluminium (high purity).
Ulwakhiwo lwelayini:
Ukuqwalasela inani elikhulu lezitshisi kwi-oven eqhekekayo kunye neempawu ze-oven ethe nkqo efana nebhokisi kwisakhiwo sayo kwaye ngokusekelwe kwiminyaka emininzi yamava ethu oyilo nokwakha, i-oven ephezulu isebenzisa ulwakhiwo lweeleya ezimbini ze-CCEWOOL high aluminium (okanye ubumsulwa obuphezulu) ii-ceramic fiber blankets + ii-central hoisting fiber components. Ii-fiber components zingafakwa kwaye ziqiniswe ngokuqinileyo kwisakhiwo se-engile yentsimbi okanye i-plug-in fiber component kwiindonga ze-oven, kwaye ulwakhiwo lukhawuleza kwaye lulula kunye nokuqhaqha kunye nokuhlanganiswa ngexesha lokugcinwa. I-fiber lining ilungile, kwaye ukusebenza kwe-heat insulation kuyamangalisa.
Uhlobo lolungiselelo lokufakelwa kwe-fiber lining:
Ngokusekelwe kwiimpawu zesakhiwo sesakhiwo sokubambelela seenxalenye zefayibha, iinxalenye zefayibha eziphakamisa umngxuma ophakathi phezulu kwesithando zenza ulungiselelo "lomgangatho weparquet". Iinxalenye zefayibha ze-engile okanye ze-plug-in ezindongeni zesithando zicwangciswe kwicala elifanayo ngokulandelelana kwicala lokusonga. Iingubo zefayibha zezinto ezifanayo kwimigca eyahlukeneyo zisongwa zibe yi-U ukuze zibuyisele ukuncitshiswa kwefayibha.
