Cov qauv ntawm lub cub tawg me me muaj kev txiav txim siab ntawm cov kev taw qhia, kev ceev, cua-gas mixing degree thiab nplaim taws ntev ntawm cov nplaim taws. Lub preheating kub ntawm huab cua-gas thiab tus nqi ntawm cov huab cua ntau dhau los txiav txim siab qhov chaw ntawm cov nplaim taws thiab qhov kub ntawm cov nplaim taws. Yog li ntawd, cov qauv ntawm lub cub tawg me me ua lub luag haujlwm tseem ceeb hauv kev hloov hluav taws xob hauv cov kiln thiab cov txheej txheem melting ntawm iav.
Rau melting furnaces burns kua fuels, natural gas thiab coke cub gas, tus qauv ntawm lub cub tawg me me yog yooj yim, tsuas yog ib tug me me rauv qhov hluav taws xob thiab ib tug kab rov tav channel. Rau melting furnaces burner tsim roj, ntxiv rau lub qhov hluav taws xob thiab kab rov tav channel, lub cub me me kuj muaj ib tug pre-combustion chamber, ib tug me me rauv tus nplaig, ib tug cua riser thiab ib tug roj riser.
1. Lub qhov hluav taws xob
Lub qhov hluav taws xob kuj hu ua qhov hluav taws kub. Nws yog qhov chaw uas cov nplaim hluav taws tau tawm mus rau hauv qhov cub thiab qhov chaw uas cov pa hluav taws xob nqus tawm ntawm qhov cub. Thaum tus nqi ntws ntawm huab cua (thiab roj) thiab qhov kub thiab txias ntawm cov nplaim hluav taws yog qhov tas li, qhov loj ntawm qhov chaw hla ntawm qhov hluav taws xob txiav txim siab qhov ceev ntawm cov nplaim taws tawm mus rau hauv qhov cub thiab tseem cuam tshuam rau qhov ntev ntawm qhov hluav taws xob. nplaim taws. Thaum qhov chaw hla ntu ntawm lub nozzle tsis tu ncua, qhov sib piv ntawm qhov ntev mus rau qhov siab ntawm lub nozzle txiav txim siab thaj tsam ntawm cov nplaim taws ntawm cov iav kua nplaum.
Loj dhau los yog me me dhau qhov nplaim taws ceev tsis yog qhov ua tau zoo rau kev ua tiav ntawm cov txheej txheem melting. Yog hais tias qhov ceev yog loj heev, cov roj yuav tsis muaj sij hawm los hlawv tag nrho thiab yuav txuas mus rau lub qhov cub me me, los yog txawm hlawv nyob rau hauv lub tshav kub cia chamber, uas yog tsis conducive mus rau lub melting ntawm iav nyob rau hauv lub kiln, thiab nws. yog ib qho yooj yim rau hlawv lub qhov cub me me, qhov chaw cia cua sov thiab cov latticerefractory cibs. Nyob rau tib lub sijhawm, yog tias cov nplaim hluav taws kub loj dhau lawm, cov hmoov yuav raug coj mus rau hauv lub qhov cub me me, corroding lub masonry ntawm ntau qhov chaw ntawm lub cub tawg me me thiab thaiv lub lattice lub cev. Yog tias cov nplaim hluav taws kub me me dhau lawm, cov nplaim taws yuav ntab thiab tsis muaj zog, uas tsis tsim nyog rau cov cua kub hloov ntawm cov iav kua thiab cov khoom siv batch, thiab nws yog ib qho yooj yim rau hlawv lub tiaj tiaj ntawm lub nozzle ntawm lub cub tawg me me. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, nws yog qhov yuav tsum tau ua kom qhov dav ntawm lub nozzle kom ntau li ntau tau. Qhov chaw hla ntu ntawm lub nozzle feem ntau yog tiaj tus kom tau raws li qhov kev pab them nqi. Feem ntau, qhov dav ntawm lub nozzle sib txawv raws li qhov xav tau ntawm qhov kub thiab txias hauv qhov cub. Rau lub qhov cub melting nrog 7 khub ntawm qhov cub me me, qhov dav ntawm 1 #, 2 #, thiab 6 # me rauv yog tib yam, qhov dav ntawm lub taub hau ntawm 3 #, 4 #, thiab 5 # me rauv me me, thiab lub nozzle ntawm 7 # qhov cub me me yog qhov tsawg tshaj plaws.
Lub koov nyob rau sab saum toj ntawm lub nozzle yog hu ua pem hauv ntej ca arch ntawm lub cub tawg me me; cov phab ntsa ntawm ob sab ntawm lub nozzle yog hu ua lub cub tawg me me, thiab lub cub tawg me me hook bricks hauv qab no. Txij li cov nplaim hluav taws raug txau rau hauv qhov cub lossis cov roj kub kub hauv qhov cub yog tawm los ntawm lub nozzle, cov nplaim hluav taws kub hnyiab thiab ya cov khoom yaig ua rau ib puag ncig siv tsis zoo, yog li cov cam khwb cia fused zirconium corundum refractory cib yog siv rau masonry ntau yam. qhov chaw ntawm lub nozzle.
Qhov kev ncua deb ntawm lub nozzle thiab cov kua nto yog feem ntau yuav tsum yog me me li sai tau, kom cov nplaim hluav taws nyob ze rau cov kua nto, uas yog qhov zoo rau kev hloov cua sov. Feem ntau, qhov kev ncua deb ntawm lub hauv qab cib ntawm lub nozzle thiab iav kua nto yog 400 ~ 600mm.
2. Precombustion chamber
Rau lub melting furnace burner gas, qhov chaw me me ntawm qhov cub hluav taws xob los ntawm qhov kawg ntawm tus nplaig mus rau sab ntug ntawm lub nozzle yog hu ua precombustion chamber. Tom qab cov cua preheated thiab roj nkag los ntawm sab sauv thiab qis ntawm tus nplaig koov raws li, lawv sib ntsib nyob rau hauv pem hauv ntej ntawm tus nplaig, diffuse thiab sib tsoo nrog ib leeg kom sib tov, hlawv mus rau ib qho twg, thiab tshuaj tsuag rau hauv qhov cub ntawm ib qho. lub kaum sab xis. Txhawm rau kom ntseeg tau tias cov roj tuaj yeem raug hlawv tag nrho hauv qhov cub, lub chamber precombustion plays lub luag haujlwm zoo, yog li qhov ntev ntawm lub chamber precombustion (piv txwv li qhov kev ncua deb ntawm kev sib xyaw ua ke ntawm huab cua thiab roj) kuj qhia txog lub sijhawm sib xyaw combustion. , uas yog qhov taw qhia tseem ceeb ntawm cov qauv.
Rau lub qhov cub melting uas kub hnyiab tau rau ntawm lub cub tawg me me los ntawm kev ntxig rau sab, sab saum toj lossis hauv qab ntxig ntawm rab phom tsuag, qhov chaw nyob hauv qhov cub me me kuj hu ua precombustion chamber. Rau lub qhov cub melting uas hlawv cov roj ua kua thiab cov roj ntuj los ntawm cov hauv qab ntawm lub cub tawg me me, qhov chaw nyob hauv qhov cub me me yog hu ua cua channel.
Lub precombustion chamber yog tsim los ntawm txoj kab nqes hav, ib lub qhov cub me me sab phab ntsa thiab lub cub tawg me me hauv qab phaj. Lub qhov cub me me hauv qab phaj yog tsim los ntawm cov hauv qab refractory cib, cam khwb cia hlau daim hlau los yog cov txheej txheem channel steels; lub lateral thrust ntawm txoj kab nqes koov yog yug los ntawm txoj hlua khi ntawm I-beam kab ntawm ob sab ntawm lub qhov cub me me. Cov qauv ntawm lub precombustion chamber yog ib qho tseem ceeb hauv lub koom haum ntawm cov nplaim taws ntawm tag nrho cov kiln. Lub brickwork ntawm lub pre-combustion chamber yog nyob rau hauv kev sib cuag nrog cov high-kub nplaim, yog li txoj kab nqes koov thiab sab phab ntsa siv 33# zoo tib yam cam khwb cia fused zirconium corundum cib, thiab cov me me rauv hauv qab cib siv 33# oxidation txoj kev uas tsis yog shrinkage fused. zirconium corundum cib. Qhov nqes hav thiab sab phab ntsa yog insulated los ntawm sab hauv mus rau sab nraud nrog zirconium sealing cov ntaub ntawv, high-aluminium rwb thaiv tsev bricks thiab rwb thaiv tsev txheej; lub qhov cub me me hauv qab yog insulated los ntawm sab hauv mus rau sab nraud nrog zirconium sealing cov ntaub ntawv thiab high-aluminium cib; thiab muaj ib lub hnab dej tiaj tus hauv qab no kom txo tau qhov kev khiav hauj lwm qhov kub thiab txias thaum kuaj xyuas thiab hloov lub nozzle.
