Lub pas dej hauv qab bubbling tshuab yog teem ib los yog ob kab ntawm bubbling ntsiab lus nyob rau hauv lub pas dej ua ke hauv qab ntawm lub melting cheeb tsam thiab lub clarification cheeb tsam ntawm lub iav melting rauv, yog li bubbling ib tug tej yam siab ntawm cov pa mus rau hauv lub kiln, thiab tsav lub iav ib puag ncig cov kua. kom txav mus los ntawm qhov nce txav ntawm cov npuas tsis ua kom puas lub cev convection ntawm cov kua iav, yog li txhawb kev nthuav dav thiab homogenization ntawm cov kua iav.
Qhov zoo ntawm Bubbling Technology
Tom qab bubbling, lub voj voog ua kua ntws los ntawm hauv qab mus rau sab saum toj yog ntxiv ze ntawm qhov chaw kub ntawm lub khob melting rauv, raws li qhia hauv daim duab 1, kom cov cua sov convection tsim los ntawm qhov chaw kub yog ntxiv dag zog, uas tuaj yeem cuam tshuam cov khoom siv hluav taws xob zoo. tseem tsis tau yaj los ntawm ntws mus rau thaj chaw qhia meej. Qhov nce ntawm npuas ua rau lub zog ntawm cov iav ib puag ncig cov kua thiab txhawb nqa kev tshem tawm npuas hauv cov kua iav. Kev ua haujlwm ntawm kev ua npuas dej ua rau muaj qhov kub thiab txias ntawm cov kua iav hauv qab ntawm lub pas dej, ntxiv dag zog rau kev sib hloov ntawm cov iav kua, tuaj yeem txhim kho cov tshuaj sib xws thiab thermal uniformity ntawm cov iav kua, txhim kho cov khoom sib xws ntawm iav. , thiab txo qhov tsis xws luag xws li npuas, pob zeb thiab streaks hauv cov khoom. Bubbling kuj tuaj yeem ua rau kom lub ntim tawm thiab txuag lub zog. Hauv kev tsim cov khoom siv iav ntau yam, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem melting ntawm cov xim iav nrog cov cua sov permeability xws li xim av thiab ntsuab, cov tshuab bubbling zoo dua.
Qauv thiab installation ntawm bubbling nozzle
Vim tias qhov kub thiab txias ntawm cov kua iav hauv qab ntawm lub pas dej tau nce ntau heev tom qab bubbling, qhov khiav ceev ntawm cov iav kua nyob ze ntawm lub nozzle yog ceev, tshwj xeeb tshaj yog cov iav kua nyob rau hauv lub immovable txheej nyob rau hauv qab ntawm lub pas dej ua ke yog tseem koom nyob rau hauv lub ntws, yog li aggravating erosion ntawm refractory bricks cov ntaub ntawv nyob rau hauv qab ntawm lub pas dej ua ke ze ntawm lub bubbling point. Yog tias nws tsis ua haujlwm zoo, nws yog qhov yooj yim los ua kom tawg thiab ua rau lub neej luv luv. Yog li ntawd, lub bubbling nozzle yuav tsum tiv taus kub, yaig, siab zog, thiab tsis yooj yim rau oxidize. Feem ntau siv cov ntaub ntawv xws li platinum thiab platinum rhodium (raws li lub taub hau ntawm lub nozzle), cov cua sov-resistant steel, corundum, silicon dimolybdenum, hlau ceramics, thiab lwm yam. Lub puab txoj kab uas hla ntawm lub bubbling nozzle feem ntau yog 1 ~ 3 hli, thiab ib tug xov tooj ntawm me me. Qhov feem ntau qhib ntawm lub nozzle, uas yog yooj yim rau kev tsim npuas thiab tuaj yeem tiv thaiv cov iav kua los ntawm ntws rov qab mus rau hauv lub bubbling nozzle. Lub nozzle refractory bricks yuav tsum tau ua los ntawm 41 oxidation txoj kev AZS cib nrog muaj zog corrosion kuj. Tsis tas li ntawd, ob kab ntawm lub pas dej hauv qab cib ua ntej thiab tom qab lub pob zeb nozzle yuav tsum yog 50 ~ 100 hli siab tshaj lwm cov pas dej hauv qab cib, thiab cov pob zeb nozzle yuav tsum yog 50 ~ 100 hli siab tshaj ob kab ntawm lub pas dej hauv qab cib ua ntej thiab tom qab, tsim ib qho kev taw qhia, raws li qhia hauv daim duab 2. Qhov tob ntawm lub bubbling nozzle rau hauv cov kua iav yog qhov tseem ceeb heev rau bubbling. Yog tias nws mus tob heev, cov nyhuv nplawm ntawm cov kua iav tsis muaj zog txaus, thiab cov iav viscosity tsawg, thiab cov iav kua yog yooj yim ntws rov qab rau hauv lub nozzle thaum lub sij hawm bubbling; Yog hais tias nws mus tob heev, qhov yaig ntawm cov khoom siv refractory bricks nyob rau hauv qab ntawm lub pas dej ua ke yog hnyav heev, uas yuav cuam tshuam rau lub neej ntawm lub melting rauv. Lub nozzle feem ntau yog 200 ~ 500mm siab tshaj lub pas dej hauv qab thiab 50 ~ 100mm siab tshaj lub nozzle cib los tiv thaiv cov iav kua los ntawm ntws ceev heev thiab scouring lub bubbler nozzle thiab ua rau lub bubbler raj raug thaiv.
