Ezweni elikhulu lokukhiqizwa kwezimboni, izixhumanisi eziningi ezibalulekile azikwazi ukwenza ngaphandle kokusekelwa kwezinto ezisebenza kahle kakhulu. Namuhla, sizokwethula okubalulekile okudlala indima ebalulekile ezimbonini zendabuko ezifana nama-kilns kanye nezinhlelo zokususa i-sulfurization -ukusabela sintered silicon carbide zobumba.
Iyini i-silicon carbide ceramic?
I-Silicon carbide ceramic yi-ceramic material ethuthukisiwe eyakhiwe nge-silicon ne-carbon. Akuyona i-ceramic evamile, kodwa "i-metamaterial" enezici eziningi ezinhle kakhulu. Inezici zamandla okushisa aphezulu, ukumelana okuhle kokugqoka, i-coefficient ephansi yokwanda okushisayo, ubunzima obuphezulu, nokumelana nokubola kwamakhemikhali, okwenza ivelele phakathi kwezinto eziningi.
I-Reaction sintered silicon carbide ceramics iwuhlobo olukhethekile lwe-silicon carbide ceramics, futhi inqubo yabo yokulungiselela ihluke kakhulu - okokuqala, izinhlayiya ezinhle ze-alpha SiC nezithasiselo zicindezelwa emzimbeni oluhlaza, bese kuthintwa nge-silicon ewuketshezi ekushiseni okuphezulu. Kuleli qophelo, ikhabhoni engenalutho ibhekana nokusabela kwamakhemikhali okumangalisayo ne-Si efakiwe, ikhiqiza u-β - SiC futhi ibophe ngokuqinile no-α - SiC. Ngesikhathi esifanayo, i-silicon yamahhala igcwalisa ama-pores, ekugcineni ithola i-ceramic material eminyene kakhulu.
Itshe legumbi eziko
I-rection sintering ye-silicon carbide ceramics iyindima ebaluleke kakhulu futhi ebalulekile kumakhilni ahlukahlukene okushisa aphezulu. Isibonelo, kumakhilo okukhiqiza e-ceramic afana nama-roller kilns, ama-tunnel kilns, ama-shuttle kilns, njll., wenziwa izingxenye ezibalulekile njengemikhono ye-nozzle, ama-crossbeam roller, namapayipi omoya abandayo.
Umkhono wenozzle yelangabi ungalawula ngempumelelo ibhalansi yezinga lokushisa ngaphakathi kuhho. Inezici zamandla okushisa aphezulu, ukumelana ne-oxidation, ukumelana nokugqoka, nokumelana nokupholisa okusheshayo nokushisa. Ngeke iphuke noma ikhubazeke ngemva kokusetshenziswa kwesikhathi eside kwezinga lokushisa, iqinisekisa izinga lokushisa elizinzile kuhhavini. Kubalulekile ukudubula imikhiqizo ye-ceramic yekhwalithi ephezulu.
Amarola e-crossbeam namapayipi omoya abandayo ngokulandelana kwawo anomthwalo wemfanelo obalulekile wokusekela kanye nokukhipha umoya. I-crossbeam roller inezici zokuzinza okuhle kwe-thermal, ukumelana ne-oxidation, kanye nokumelana nokukhuphuka kwezinga lokushisa eliphezulu. Akulula ukuguqula nokugoba ngemva kokusetshenziswa isikhathi eside emazingeni okushisa aphezulu, ukuqinisekisa ukuzinza kwesakhiwo sangaphakathi seziko kanye nokuhamba kwezinto ezibushelelezi. I-cold air duct inesibopho sokulawula ukugeleza kwegesi kanye nokusabalalisa izinga lokushisa ngaphakathi kwesithando somlilo, ukuqinisekisa ukusebenza okuvamile kwehhavini.
Ngokombono wezingxenye ezenziwe ngokwezifiso, i-react sintered silicon carbide inezinzuzo ezisobala ekukhiqizeni izingxenye zomlilo. Ngenxa yobukhulu bayo obucishe bushintshe ngaphambi nangemva kokucwiliswa, ingacutshungulwa ibe yinoma yikuphi ukuma nosayizi ngemva kokubunjwa. Abakhiqizi beziko bangenza ngendlela oyifisayo ubujamo obuhlukahlukene kanye nokucaciswa kwezingxenye ngokuya ngemiklamo ehlukene yeziko kanye nezidingo zokukhiqiza, bahlangabezane nezidingo zokukhiqiza zemikhiqizo emise okwezinga elikhulu neyinkimbinkimbi, okunzima ukuthi ezinye izinto zifezeke.
Umugqa wokuvikela oqinile wesistimu ye-desulfurization
Emkhakheni wokuvikelwa kwemvelo okufana ne-power plant desulfurization, i-reaction sintered silicon carbide ceramics nayo idlala indima ebalulekile, ibonakala kakhulu engxenyeni eyinhloko yamabhomu e-desulfurization. I-flue gas ekhishwa ezitshalweni zikagesi iqukethe inani elikhulu lokungcola okufana ne-sulfur dioxide, futhi imibhobho ye-desulfurization ingamathuluzi abalulekile okususa lezi zinto ezingcolile.
I-reaction sintered silicon carbide desulfurization nozzle inezinto ezinhle kakhulu ezifana namandla aphezulu, ubulukhuni obuphezulu, ukumelana nokugqwala okuqinile, ukumelana nokugqoka, nokumelana nezinga lokushisa eliphezulu. Inokuphila kwenkonzo okungavamile ngaphansi kwezimo ezinzima, ezingenakuqhathaniswa nezinto ezivamile. Izinhlobo ezivame ukusetshenziswa ze-desulfurization nozzles zihlanganisa imibhobho e-spiral kanye nama-vortex nozzles, anemiklamo ehlukene nezimiso zokusebenza, kodwa angakwazi ukwenza i-atomize i-desulfurizer futhi ixhumane nayo ngokugcwele ne-flue gas, ngaleyo ndlela izuze umphumela omuhle we-desulfurization.
Ngomklamo oyingqayizivele wesakhiwo, umlomo wombhobho ovunguzayo wenza uketshezi olukulwelwesi olungaphandle lushaye indawo ezungezayo endaweni ethile ku-engeli ethile ku-nozzle, lushintshe indlela yokufafaza bese lushiya umlomo wombhobho, kwakheka inkungu eqinile eyindilinga, enganikeza ama-engeli ahlukahlukene wokufutha, futhi isenamandla aphezulu okumunca ngaphansi kwengcindezi ephansi kakhulu. I-vortex nozzle ivumela i-slurry ukuthi ingene egumbini elishwibayo lombhobho lisuka lapho libheke khona, bese likhipha i-orifice ngama-engeli angakwesokudla liye lapho lingena khona. I-spray incane futhi ifana, futhi isiteshi se-vortex sikhulu, okungekho lula ukuvinjelwa.
Ezingxenyeni ezenziwe ngokwezifiso zezinhlelo ze-desulfurization, i-react sintered silicon carbide ingenza ngendlela oyifisayo umumo we-nozzle ofaneleke kakhulu, usayizi, kanye nezici zokufutha ngokuya ngezinqubo ezihlukene ze-desulfurization, amazinga okugeleza kwegesi e-flue, ukugxila, kanye neminye imingcele, iqinisekisa ukusebenza kahle nokuzinzile kohlelo lwe-desulfurization kanye nokuhlangabezana nezidingo eziqinile zemvelo.
Izitsha zobumba ze-silicon carbide ze-reaction sintered zidlala indima engenakuthathelwa indawo emikhakheni yezimboni yendabuko efana nama-kilns nezinhlelo zokususa i-sulfurization ngenxa yezindawo zazo ezihlukile kanye nezinzuzo ezingenziwa ngendlela oyifisayo. Banikeza isiqinisekiso esiqinile sokusebenza okuphumelelayo, okuzinzile, nokuhambisana nemvelo kokukhiqizwa kwezimboni futhi bafaka umfutho oqinile ekuthuthukisweni kwezobuchwepheshe kanye nokuthuthukiswa kwezimboni zendabuko.
