Izithando Zomlilo Zohlobo Lwensimbi

Ukubuka konke:
Izithando zohlobo lwe-bell zisetshenziswa kakhulu ekufakweni kokushisa okukhanyayo kanye nokwelashwa kokushisa, ngakho-ke ziyizithando zokushisa ezihlukahlukene ngezikhathi ezithile. Izinga lokushisa lihlala phakathi kuka-650 no-1100 ℃ ikakhulukazi, futhi liyashintsha ngesikhathi esichazwe ohlelweni lokushisa. Ngokusekelwe ekulayishweni kwezithando zohlobo lwe-bell, kunezinhlobo ezimbili: isithando sohlobo lwe-bell esiyisikwele kanye nesithando sohlobo lwe-bell esiyindilinga. Imithombo yokushisa yezithando zohlobo lwe-bell ikakhulukazi igesi, ilandelwe ugesi kanye namafutha alula. Ngokuvamile, izithando zohlobo lwe-bell zakhiwe izingxenye ezintathu: isivalo sangaphandle, isivalo sangaphakathi, kanye nesitofu. Idivayisi yokushisa ivame ukufakwa esivalweni sangaphandle esifakwe ungqimba lokushisa, kuyilapho izinto zokusebenza zifakwa esivalweni sangaphakathi ukuze kufudunyezwe futhi kuphole.

Izithando zohlobo lwe-bell zinomoya oqinile, zilahlekelwa ukushisa okuphansi, futhi zisebenza kahle kakhulu ekushiseni. Ngaphezu kwalokho, azidingi umnyango wesithando noma indlela yokuphakamisa kanye nezinye izindlela ezahlukene zokudlulisa imishini, ngakho zonga izindleko futhi zisetshenziswa kabanzi ezithandweni zokushisa zezinto zokusebenza.
Izidingo ezimbili ezibaluleke kakhulu zezinto zokufakelwa kwesithando isisindo esincane kanye nokusebenza kahle kwamandla kwezimbozo zokushisa.

Izinkinga ezivamile nge-refracto yendabuko elulaizitini ze-ry noma i-st elula yokuphothaIzakhiwo zihlanganisa:

1. Izinto ezivuselelayo ezinobukhulu obukhulu obuthile (ngokuvamile izitini ezivuselelayo ezilula ezivamile zinobukhulu obuthile obungu-600KG/m3 noma ngaphezulu; izinto ezivuselelayo ezilula zino-1000 KG/m3 noma ngaphezulu) zidinga umthwalo omkhulu esakhiweni sensimbi sesembozo sesithando somlilo, ngakho kokubili ukusetshenziswa kwesakhiwo sensimbi kanye nokutshalwa kwezimali ekwakhiweni kwesithando somlilo kuyanda.

2. Isembozo sangaphandle esikhulu sithinta amandla okuphakamisa kanye nendawo yaphansi yezindawo zokukhiqiza.

3. Isithando somlilo esifana nensimbi sisebenza emazingeni okushisa ahlukahlukene ngezikhathi ezithile, futhi izitini ezikhanyayo noma ezikhanyayo zinamandla okushisa amakhulu athile, zikwazi ukudlulisa ukushisa okuphezulu, futhi zisebenzisa amandla amaningi.

Kodwa-ke, imikhiqizo ye-CCEWOOL refractory fiber ine-conductivity ephansi yokushisa, isitoreji esiphansi sokushisa, kanye nobuningi obuphansi bevolumu, okuyizizathu ezibalulekile zokusetshenziswa kwayo kabanzi ezimbozweni zokushisa. Izici zimi kanje:

1. Ububanzi bokushisa bokusebenza obubanzi kanye namafomu ahlukahlukene okufaka isicelo
Ngokuthuthuka kokukhiqizwa kwe-CCEWOOL ceramic fiber kanye nobuchwepheshe, imikhiqizo ye-CCEWOOL ceramic fiber ifinyelele ukuhlelwa kanye nokusebenza kwayo. Ngokuphathelene nokushisa, imikhiqizo ingahlangabezana nezidingo zamazinga okushisa ahlukene asukela ku-600 ℃ kuya ku-1500 ℃. Ngokuphathelene nokwakheka, imikhiqizo iye yathuthukisa kancane kancane izinhlobo ezahlukene zokucubungula noma imikhiqizo yokucubungula ejulile kusukela kukotini wendabuko, izingubo zokulala, imikhiqizo yefelthi kuya kumamojula efayibha, amabhodi, izingxenye ezibunjwe ngokukhethekile, iphepha, izindwangu zefayibha njalo njalo. Ingahlangabezana ngokugcwele nezidingo zama-oven ezimboni zemikhiqizo yefayibha yefayibha ezimbonini ezahlukahlukene.
2. Ubuningi bevolumu encane:
Ubuningi bemikhiqizo yefayibha ye-ceramic ngokuvamile buyi-96 ~ 160kg/m3, okungaba yi-1/3 yezitini ezilula kanye ne-1/5 yezinto ezingasetshenziswa kalula. Esithandweni esisanda kuklanywa, ukusetshenziswa kwemikhiqizo yefayibha ye-ceramic akugcini nje ngokusindisa insimbi, kodwa futhi kwenza ukulayisha/ukukhulula nokuthutha kube lula, kuqhubekisele phambili intuthuko kwezobuchwepheshe besithando sezimboni.
3. Umthamo omncane wokushisa kanye nendawo yokugcina ukushisa:
Uma kuqhathaniswa nezitini ezijikijelayo nezitini zokufaka izinto zokuvikela, umthamo wemikhiqizo yefayibha ye-ceramic uphansi kakhulu, cishe u-1/14-1/13 wezitini ezijikijelayo kanye no-1/7-1/6 wezitini zokufaka izinto zokuvikela. Esithandweni somlilo esisebenza ngezikhathi ezithile, inani elikhulu lokusetshenziswa kukaphethiloli okuhlobene nokukhiqiza lingagcinwa.
4. Ukwakhiwa okulula, isikhathi esifushane
Njengoba izingubo zokulala ze-ceramic kanye namamojula anokunwebeka okuhle kakhulu, inani lokucindezelwa lingabikezelwa, futhi asikho isidingo sokushiya amalunga okunwebeka ngesikhathi sokwakha. Ngenxa yalokho, ukwakhiwa kulula futhi kuqedwa yizisebenzi ezinekhono ezivamile.
5. Ukusebenza ngaphandle kwehhavini
Ngokusebenzisa ulwelwesi olugcwele i-fiber, izithando zingashiswa ngokushesha ziye ekushiseni kwenqubo uma zingavinjelwa ezinye izingxenye zensimbi, okuthuthukisa kakhulu ukusetshenziswa kahle kwezithando zezimboni futhi kunciphisa ukusetshenziswa kukaphethiloli okuhlobene nokungakhiqizi.
6. Ukushisa okuphansi kakhulu
I-Ceramic fiber iyinhlanganisela ye-fiber enobubanzi obungu-3-5um, ngakho-ke inokushisa okuphansi kakhulu. Isibonelo, lapho ingubo ye-fiber ye-aluminium ephezulu enobukhulu obungu-128kg/m3 ifinyelela ku-1000℃ endaweni eshisayo, i-coefficient yayo yokudlulisa ukushisa ingu-0.22(W/MK) kuphela.
7. Ukuqina okuhle kwamakhemikhali kanye nokumelana nokuguguleka komoya:
I-fiber ye-ceramic ingaguguleka kuphela ku-phosphoric acid, i-hydrofluoric acid, kanye ne-alkali eshisayo, futhi izinzile kwezinye izinto ezigqwalisayo. Ngaphezu kwalokho, amamojula e-fiber ye-ceramic enziwa ngokugoqa njalo ama-blanket e-fiber ye-ceramic ngesilinganiso esithile sokucindezela. Ngemva kokuba ubuso buphathwe, ukumelana nokuguguleka komoya kungafinyelela ku-30m/s.
