Ukuklama nokwakhiwa kwezitofu ze-hydrogenation
Ukubuka konke:
Isithando somlilo se-hydrogenation uhlobo lwesithando somlilo esishubhu, esihlanza futhi sicwenge uwoyela ongahluziwe ngokususa ukungcola kwawo, njenge-sulfur, i-oxygen, ne-nitrogen, kanye nokugcwala kwe-olefin ngesikhathi se-hydrogenation, ngokusebenzisa ukusabela kokuqhekeka kanye ne-isomerization ngokucindezela okuphezulu (100-150Kg/Cm2) kanye nokushisa (370-430℃). Ngokusekelwe ezinhlotsheni ezahlukene zamafutha angahluziwe acwengiwe, kunezithando ze-hydrogenation zedizili, izithando ze-hydrodesulfurization zamafutha asele, izithando ze-hydrogenation zokuhlanza uphethiloli njalo njalo.
Isakhiwo sesithando sokushisa esinomoya oshisayo sifana nesosithando sokushisa esivamile esinomoya oshisayo, ngesimo sesilinda noma ibhokisi. Isithando somlilo ngasinye sakhiwe yigumbi lemisebe kanye negumbi le-convection. Ukushisa ekamelweni le-radiant kudluliselwa ikakhulukazi yimisebe, kanti ukushisa ekamelweni le-convection kudluliselwa ikakhulukazi yi-convection. Ngokwezimo zokusabela ze-hydrogenation, ukuqhekeka, kanye ne-isomerization, izinga lokushisa lesithando somlilo esinomoya oshisayo lingaba ngu-900°C. Ngenxa yezici ezingenhla zesithando somlilo esinomoya oshisayo, ulwelwesi lwefayibha ngokuvamile lusetshenziselwa izindonga kanye nengxenye ephezulu yegumbi le-radiant. Ikamelo le-convection ngokuvamile libunjwa nge-refractory castable.
Ukunquma izinto zokwakha ulwelwesi:
Uma sibhekaizinga lokushisa lesithando (ngokuvamile cishe900℃)futhiumoya obuthakathaka wokunciphisakuihisithando sokushisa i-hydrogenationkanye neiminyaka yethu yolwazi lokuklama nokwakha kanyeiqiniso lokuthiinani elikhulu leizitofu ngokuvamile zisatshalaliswa esithandweni somlilo phezulu nangaphansi kanye nasezinhlangothini zodonga, izinto zokwembozaisithando sokushisa i-hydrogenationkunqunywe ukuthi kufaka phakathi ulwelwesi lwezitini olukhanyayo lwe-CCEFIRE oluyi-1.8-2.5m ubude. Izingxenye ezisele zisebenzisa izingxenye ze-fiber ceramic ze-CCEWOOL ezine-aluminium ephezulu njengezinto ezishisayo zolwelwesi, kanti izinto zolwelwesi lwangemuva lwezingxenye ze-fiber ceramic kanye nezitini ezikhanyayo zisebenzisa izingubo zokulala ze-fiber ezijwayelekile ze-CCEWOOL.
Isakhiwo sendwangu:
Ngokusho kokusatshalaliswa kwama-nozzle okushisa esithandweni se-hydrogenation, kunezinhlobo ezimbili zezakhiwo zesithando somlilo: isithando somlilo esiyisilinda kanye nesithando somlilo sebhokisi, ngakho-ke kunezinhlobo ezimbili zesakhiwo.
Isithando somlilo esiyisilinda:
Ngokusekelwe ezicini zesakhiwo sesithando somlilo esiyisilinda, ingxenye yesitini esikhanyayo phansi kwezindonga zesithando segumbi elikhanyayo kufanele ifakwe amathayela ngamablanketi e-CCEWOOL ceramic fiber, bese ibekwa ngezitini ezikhanyayo ze-CCEFIRE; izingxenye ezisele zingafakwa amathayela ngezingqimba ezimbili zamablanketi e-ceramic fiber ajwayelekile e-CCEWOOL, bese ibekwa ngezingxenye ze-ceramic fiber ezine-aluminium ephezulu esakhiweni sokubambelela se-herringbone.
Ingxenye ephezulu yesithando somlilo isebenzisa izendlalelo ezimbili zezingubo zokulala ze-ceramic ezijwayelekile ze-CCEWOOL, bese zihlanganiswa ngamamojula e-aluminium aphezulu esakhiweni se-anchor esilengayo esinembobo eyodwa kanye namamojula okugoqa ahlanganiswe odongeni lwesithando somlilo futhi aqiniswe ngezikulufo.
Isithando somlilo sebhokisi:
Ngokusekelwe ezicini zesakhiwo sesithando sebhokisi, ingxenye yesitini esikhanyayo phansi kwezindonga zesithando segumbi elikhazimulayo kufanele ifakwe amathayela ngamablanketi e-CCEWOOL ceramic fiber, bese ibekwa ngezitini ze-CCEFIRE lightweight refractory; okunye kungafakwa amathayela ngezingqimba ezimbili zamablanketi e-ceramic fiber ajwayelekile e-CCEWOOL, bese ibekwa ngezingxenye ze-fiber ye-aluminium ephezulu esakhiweni se-angle iron anchor.
Ingxenye ephezulu yesithando isebenzisa izendlalelo ezimbili ezinamathayili zezingubo zokulala ze-ceramic ezijwayelekile ze-CCEWOOL ezihlanganiswe namamojula e-ceramic fiber e-aluminium ephezulu esakhiweni se-anchor esilengayo esinembobo eyodwa.
Lezi zinhlobo ezimbili zesakhiwo sezingxenye zefayibha ziqinile ekufakweni nasekulungisweni, futhi ukwakhiwa kuyashesha futhi kulula kakhulu. Ngaphezu kwalokho, kulula ukuzihlukanisa nokuzihlanganisa ngesikhathi sokulungiswa. Ulwelwesi lwefayibha lunobuqotho obuhle, futhi ukusebenza kokuvikela ukushisa kuyamangalisa.
Uhlobo lokufakwa kwe-fiber lining:
Ngokwezici zesakhiwo sokubambelela sezingxenye zefayibha, izindonga zesithando zisebenzisa izingxenye zefayibha "ze-herringbone" noma "ze-angle iron", ezihlelwe ngendlela efanayo eceleni kwendlela yokugoqa. Izingubo zefayibha zezinto ezifanayo phakathi kwemigqa ehlukene zigoqwa zibe yisimo se-U ukuze kulungiswe ukuncishiswa kwefayibha.
Kwizingxenye zefayibha yokuphakamisa imbobo ephakathi ezifakwe eceleni komugqa ophakathi kuya emaphethelweni esithando somlilo esiyisilinda phezulu kwesithando somlilo, kusetshenziswa ilungiselelo "lephansi lephareli"; amabhlogo okugoqa emaphethelweni aqiniswa ngezikulufo ezishiselwe ezindongeni zesithando somlilo. Amamojula okugoqa ayanda abheke ezindongeni zesithando somlilo.
Izingxenye zefayibha zokuphakamisa imbobo ephakathi phezulu kwesithando sebhokisi zamukela ilungiselelo "lephansi lephakeji".
