Kapangidwe ndi Kapangidwe ka Uvuni Wosweka
Chidule:
Chitofu chosweka ndi chida chofunikira kwambiri pakupanga ethylene yayikulu, yomwe imagwiritsa ntchito ma hydrocarbons a gaseous (ethane, propane, butane) ndi ma hydrocarbons amadzimadzi (mafuta opepuka, dizilo, dizilo yopumira) ngati zopangira.peratureya750-900ndikusweka kwa kutentha kuti apange zinthu zopangira petrochemical,monga ethane, propane, butadiene, acetylene ndi aromatics. Pali mitundu iwiri yang'anjo yosweka:ng'anjo yopepuka ya dizilo ndiang'anjo yosweka ya ethane, zonse ziwiri ndi mtundu wa ng'anjo zotenthetsera zoyima. Kapangidwe ka ng'anjo nthawi zambiri kamakhala ndi magawo awiri: gawo lapamwamba ndi gawo la convection, ndipo gawo lapansi ndi gawo la radiant. Chubu choyima cha ng'anjo chomwe chili mu gawo la radiant ndi gawo loyatsira kutentha kwa hydrocarbon ya cracking medium. Kutentha kwa ng'anjo ndi 1260°C, ndipo makoma mbali zonse ziwiri ndi pansi ali ndi zoyatsira mafuta ndi gasi. Poganizira makhalidwe omwe ali pamwambapa a cranking ng'anjo, ulusi wa ulusi nthawi zambiri umagwiritsidwa ntchito pa makoma ndi pamwamba pa chipinda chowala.
Kudziwa zipangizo zomangira:
Poganizira za kukwerakutentha kwa ng'anjo (nthawi zambiri pafupifupi 1260℃)ndimpweya wofooka wochepetsamung'anjo yoswekakomansozaka zathu zambiri zogwira ntchito yomanga ndi kupanga mapulani komansomfundo yakutikuchuluka kwakukulu kwa ming'aluZoyatsira ng'anjo nthawi zambiri zimagawidwa mu ng'anjo pansi ndipo mbali zonse ziwiri za khoma, zinthu zomangira ng'anjo yosweka zimaonedwa kuti zili ndi denga la njerwa lalitali mamita 4. Zigawo zotsalazo zimagwiritsa ntchito zigawo za ulusi zokhala ndi zirconium ngati zinthu zotentha pamwamba pa denga, pomwe zinthu zomangira kumbuyo zimagwiritsa ntchito mabulangeti a CCEWOOL high aluminium (high purity) ceramic fiber.
Kapangidwe ka m'mphepete:
Poganizira kuchuluka kwa zoyatsira moto mu ng'anjo yosweka komanso mawonekedwe a ng'anjo yotenthetsera yamtundu wa bokosi loyima komanso kutengera zaka zambiri zomwe takumana nazo popanga ndi kumanga, pamwamba pa ng'anjoyo pamagwiritsa ntchito kapangidwe ka zigawo ziwiri za CCEWOOL high aluminium (kapena high purity) ceramic fiber blankets + central hoisting fiber components. Zigawo za ulusi zimatha kuyikidwa ndikukhazikika mwamphamvu mu angle iron kapena plug-in fiber component structure pamakoma a ng'anjo, ndipo kapangidwe kake ndi kachangu komanso kosavuta komanso kuchotsedwa ndi kusonkhana panthawi yokonza. Ulusi uli ndi umphumphu wabwino, ndipo magwiridwe antchito a kutentha ndi odabwitsa.
Fomu yokhazikitsira ulusi wa fiber lining:
Kutengera ndi mawonekedwe a kapangidwe ka kapangidwe kake ka zigawo za ulusi, zigawo za ulusi wokwezera mabowo apakati pamwamba pa ng'anjo zimakhala ndi dongosolo la "pansi pa parquet". Zigawo za chitsulo cha ngodya kapena ulusi wolumikizira pamakoma a ng'anjo zimayikidwa mbali imodzi motsatizana motsatira njira yopindika. Mabulangeti a ulusi a zinthu zomwezo m'mizere yosiyanasiyana amapindidwa kukhala mawonekedwe a U kuti athandizire kuchepa kwa ulusi.
