Hauv Kev Tsim Khoom Ntawm E- iav Fiber nyob rau hauv Lub Tank Rauv, Kev Tswj Ntawm Melting Kub Thiab Nplaim...

Kev tsim tawm ntawmE- iav fiber ntau (alkali-dawb iav fiber ntau)nyob rau hauv lub tank rauv yog ib tug complex high -kub melting txheej txheem. Cov txheej txheem melting kub yog qhov tseem ceeb ntawm cov txheej txheem tswj xyuas, cuam tshuam ncaj qha rau qhov zoo ntawm cov iav molten, melting efficiency, zog noj, rauv lub neej, thiab cov khoom fiber ntau kawg. Qhov ntsuas kub no tau ua tiav los ntawm kev kho cov nplaim hluav taws xob, hluav taws xob flux, thiab lwm yam.

 

I. Melting Kub ntawm E- iav

1. Melting Temperature Range: Ua kom tiav melting thiab refining ntawm E- iav feem ntau yuav tsum tau kub heev. Nws qhov chaw melting ib txwm (kub qhov chaw) kub yog feem ntau nyob rau hauv thaj tsam ntawm 1500℃- 1600℃.

Lub hom phiaj kub tshwj xeeb nyob ntawm:

* Batch muaj pes tsawg leeg: tshwj xeeb formulations (xws li seb nws muaj fluorine, qib boron, seb nws muaj titanium, thiab lwm yam) yuav cuam tshuam rau cov yam ntxwv melting.

* Lub tshuab hluav taws xob tsim: Rauv hom, qhov loj me, cov nyhuv rwb thaiv tsev, kev teeb tsa hluav taws xob, thiab lwm yam.

* Cov hom phiaj ntau lawm: Melting tus nqi, molten iav zoo yuav tsum tau.

* Cov khoom siv refractory: qhov yaig ntawm cov ntaub ntawv refractory ntawm qhov kub thiab txias txwv qhov ntsuas kub siab. Qhov ntsuas kub hauv thaj chaw ua kom zoo yog feem ntau qis dua qhov kub ntawm qhov kub (kwv yees li 20-50℃qis dua) txhawm rau pab tshem tawm npuas thiab iav homogenization. Kev ua haujlwm kub yog qhov qis dua (feem ntau ntawm 1200℃thiab 1350 degree) coj iav mus rau qhov tsim nyog viscosity thiab ruaj khov rau kev kos duab hlau.

 

2. Qhov tseem ceeb ntawm kev tswj qhov kub thiab txias: Melting Efficiency: Kev kub siab txaus yog qhov tseem ceeb rau kev ua kom tiav cov tshuaj tiv thaiv ntawm cov ntaub ntawv batch (quartz xuab zeb, pyrophyllite, boric acid / borate, limestone, thiab lwm yam), ua kom tiav cov xuab zeb hais, thiab tso tawm tag nrho cov pa roj. Qhov kub tsis txaus ua rau "cov khoom siv raw" seem (cov khoom tsis muaj quartz), pob zeb, thiab cov npuas ntau ntxiv. Iav Zoo: Kub kub txhawb kev ua kom zoo thiab homogenization ntawm iav, txo qhov tsis xws luag xws li streaks, npuas, thiab pob zeb. Cov teeb meem no cuam tshuam rau fiber ntau zog, tawg tus nqi, thiab txuas ntxiv. Viscosity: Kub ncaj qha cuam tshuam rau viscosity ntawm iav. Hlau daim duab yuav tsum tau iav nyob rau hauv ib tug tshwj xeeb viscosity ntau yam. Refractory Material Erosion: Kub kub ntau heev ua rau kom yaig ntawm cov khoom siv refractory (tshwj xeeb tshaj yog fused zirconia- corundum cib, AZS), ua rau lub neej luv luv thiab muaj peev xwm qhia txog kev tsim pob zeb refractory.

Kev siv hluav taws xob: Kev tswj qhov kub thiab txias yog qhov tseem ceeb ntawm kev siv hluav taws xob hauv pas dej ua ke (feem ntau suav txog ntau dua 60% ntawm tag nrho cov khoom siv hluav taws xob). Kev tswj qhov kub thiab txias kom tsis txhob kub dhau yog qhov tseem ceeb rau kev txuag hluav taws xob.

 

II. Kev cai nplaim taws

 

Kev tswj cov nplaim taws yog cov txheej txheem tseem ceeb rau kev tswj qhov kub ntawm qhov sib faib, ua kom muaj txiaj ntsig zoo, thiab tiv thaiv cov qauv ntawm qhov cub (tshwj xeeb tshaj yog lub ntsiab arch). Nws lub hom phiaj tseem ceeb yog los tsim kom muaj qhov zoo tshaj plaws qhov kub thiab txias.

 

1. Cov Txheej Txheem Tseem Ceeb: Roj rau combustion Air Ratio (Air-Fuel Ratio), tseem hu ua Oxygen- Roj piv rau cov pa ntshiab oxygen combustion systems: Lub hom phiaj: kom ua tiav combustion. Tsis tiav combustion khib nyiab roj, txo cov nplaim hluav taws kub, ua rau cov pa luam yeeb dub (carbon deposits) uas paug cov iav molten, thiab clogs tshav kub exchangers; huab cua ntau dhau tshem tawm cov cua kub ntau, txo cov thermal efficiency thiab muaj peev xwm exacerbating arch oxidation yaig. Kev hloov kho: Cov huab cua- piv txwv roj yog tswj tau raws li qhov ntsuas hluav taws xob (O₂, CO ntsiab lus).

 

E- iav qhov cub feem ntau tswj O₂ cov ntsiab lus hauv cov pa roj mus txog 1-3% (me ntsis zoo siab combustion). Impact on Atmosphere:

 

Cov huab cua -roj piv kuj tseem cuam tshuam rau lub tshuab cua sov (oxidizing lossis txo), uas muaj kev cuam tshuam me ntsis ntawm tus cwj pwm ntawm qee yam khoom siv (xws li hlau) thiab iav xim, tab sis qhov cuam tshuam me me ntawm E- iav nws tus kheej (uas yuav tsum tsis muaj xim thiab pob tshab iav). Flame Length thiab Shape:

 

Lub Hom Phiaj: Txhawm rau tsim cov nplaim hluav taws uas npog qhov chaw ntawm lub pas dej melting, muaj qee yam nruj thiab muaj peev xwm sib kis. Nplaim ntev vs. Nplaim luv:

 

Cov nplaim taws ntev: Cov cheeb tsam loj, qhov sib txawv ntawm qhov kub thiab txias, tsis tshua muaj thermal shock rau lub koov, tab sis qhov kub thiab txias hauv zos yuav tsis siab txaus, thiab nkag mus rau hauv batch "drilling" cheeb tsam yuav tsis txaus. Cov nplaim taws luv luv: Kev nruj nruj, qhov kub thiab txias hauv cheeb tsam, muaj zog nkag mus rau hauv cov txheej txheej, ua rau cov ntaub ntawv nyoos sai sai, tab sis tsis sib xws, yooj yim ua rau cov cua sov hauv zos (qhov kub kub yog qhov tseem ceeb), thiab thermal poob siab rau lub koov thiab lub mis phab ntsa. Kev hloov kho: Ua tiav los ntawm kev kho lub kaum sab xis ntawm lub qhov hluav taws xob, roj / cua txhaj tshuaj tshaj tawm (momentum piv), kev siv zog, thiab lwm yam.

 

Niaj hnub nimno tank furnaces feem ntau siv ntau-theem adjustable burners. Nplaim taw qhia (lub kaum sab xis): Lub Hom Phiaj:

 

Txhawm rau hloov cov cua sov kom zoo rau cov khoom siv thiab cov iav yaj, tsis txhob cuam tshuam cov nplaim hluav taws ncaj qha rau ntawm koov lossis phab ntsa ntawm lub mis. Adjustment: Kho lub suab thiab kab rov tav lub kaum sab xis ntawm lub burner lance. Pitch lub kaum sab xis: cuam tshuam cov nplaim taws cuam tshuam ntawm cov khoom siv ("licking") thiab kev pab cuam ntawm cov kua dej. Tsawg dhau ntawm lub kaum sab xis (nplaim qis dhau los) yuav ua rau cov kua dej ntog los yog cov khoom siv ya mus ua rau cov phab ntsa ntawm lub mis; Lub kaum sab xis siab dhau (nplaim taws dhau mus) ua rau qis thermal efficiency thiab cua kub ntau dhau ntawm lub koov. Kab rov tav lub kaum sab xis: cuam tshuam rau kev faib cov nplaim taws hla qhov dav ntawm qhov cub thiab qhov chaw ntawm qhov chaw kub.

2. Lub Hom Phiaj ntawm Kev Kho Nplaim:

* ** Tsim Tsim Nyog Qhov Kub Kub: ** Tsim qhov kub siab tshaj plaws (kub qhov chaw) tom qab ntawm lub pas dej ua ke (feem ntau tom qab lub sump). Qhov no yog qhov chaw tseem ceeb rau kev nthuav dav thiab homogenization ntawm cov iav molten, thiab tseem yog "lub cav" tswj cov kev taw qhia ntws ntawm cov iav molten (los ntawm qhov kub kub mus rau qhov chaw pub khoom noj thiab ua haujlwm).

* **Uniform Liquid Surface Heating:** Zam tsis txhob overheating hauv zos los yog undercooling, txo convection unevenness thiab "tuag zones" tshwm sim los ntawm kub gradients.

* ** Tiv thaiv lub Kiln Structure:** Tiv thaiv cov nplaim taws los ntawm scouring lub koov thiab lub mis phab ntsa, tiv thaiv lub zos overheating los ntawm ua kom yaig sai ntawm cov ntaub ntawv refractory.

* ** Ua kom muaj cua sov hloov pauv: ** Ua kom muaj hluav taws xob ntau tshaj plaws thiab kev sib hloov hluav taws xob hloov hluav taws xob ntawm cov nplaim hluav taws ntawm cov khoom siv thiab cov iav molten.

* ** Ruaj Ruaj Ruaj Ruaj Ruaj:** Txo qhov hloov pauv thiab ua kom ruaj khov molten iav zoo.

 

III. Kev tswj kom zoo ntawm Melting Kub thiab nplaim taws kho

1. Qhov kub thiab txias yog lub hom phiaj, nplaim taws yog qhov txhais tau tias: Kev hloov pauv nplaim taws yog txoj hauv kev tseem ceeb los tswj qhov kub thiab txias hauv qhov cub (tshwj xeeb tshaj yog qhov chaw thiab qhov kub ntawm qhov kub ntawm qhov kub). 2. Kev ntsuas kub thiab kev tawm tswv yim: Kev ntsuas kub tsis tu ncua uas siv cov thermocouples thiab cov ntsuas kub infrared tso rau ntawm qhov chaw tseem ceeb hauv qhov cub (pub inlet, qhov chaw kub, qhov chaw sov, qhov kub thiab txias) ua lub hauv paus rau kev kho cov nplaim taws.
3. Tsis Siv Neeg Tswj System: Niaj hnub nimno loj - nplai tank furnaces feem ntau siv DCS/PLC systems. Raws li qhov ntsuas kub nkhaus thiab ntsuas qhov tseem ceeb, kev tswj tsis siv neeg ntawm cov nplaim taws thiab qhov kub thiab txias tau ua tiav los ntawm kev kho qhov tsis xws li roj kom muaj nuj nqis, combustion cua ntim, thiab lub kaum sab xis burner / damper.
4. Cov txheej txheem sib npaug: Nrhiav qhov zoo tshaj qhov sib npaug ntawm kev ua kom cov iav yaj zoo (siab-kub melting, zoo refining thiab homogenization), tiv thaiv cov kiln (tsis txhob kub siab heev thiab nplaim taws yaig), thiab txo lub zog noj yog qhov tseem ceeb.
