I. Qhov tseem ceeb ntawm Kev Tsim Kho Tshiab Niaj Hnub No Lime Kiln Technology

Txiv qaub yog cov khoom siv tseem ceeb thiab tseem ceeb rau kev tsim cov hlau, calcium carbide ntau lawm, refractory ntau lawm, alumina ntau lawm. Tshwj xeeb tshaj yog nyob rau hauv lub caij nyoog tshiab, cov cuab yeej tshiab, cov khoom tshiab txuas ntxiv tsim cov khoom siv calcium ntau dua thiab siv ntau dua. Kev xyaum tau ua pov thawj tias niaj hnub txiv qaub kiln thev naus laus zis yog qhov tseeb tiag tiag thiab luv luv tau txais txiaj ntsig zoo rau cov tuam txhab hlau thiab hlau, cov tuam txhab calcium carbide, cov lag luam coking thiab lwm yam. Tam sim no, cov txiaj ntsig ib tuj ntawm txiv qaub tau dhau los ntawm cov txiaj ntsig ntawm tons ntawm hlau, tons ntawm hlau, tons ntawm calcium carbide, tons ntawm coke. Cov lag luam uas tau siv cov cuab yeej siv hluav taws xob niaj hnub no tau txais txiaj ntsig zoo, thiab tau txais txiaj ntsig zoo dua rau kev sib raug zoo. Txawm li cas los xij, ntau lub tuam txhab raug txwv los ntawm kev tswj hwm ib txwm muaj kev nco qab thiab qib kev tswj hwm thiab tsis tau tsim cov cuab yeej siv hluav taws xob niaj hnub no tseem cia siab rau cov av kiln txiv qaub. Yog li ntawd, yog tias peb xav kom tswj cov pa phem ntawm cov av kiln, peb kuj yuav tsum cia siab rau kev siv cov txiv qaub niaj hnub kiln los daws cov teeb meem ntawm kev thov.

Lub npe hu ua niaj hnub tshiab thev naus laus zis txiv qaub kiln yog kev tshawb fawb ntau dua calcining txiv qaub txheej txheem nrog kev tiv thaiv ib puag ncig, kev txuag hluav taws xob, kev siv tshuab thiab automation. Vim tias cov txheej txheem no siv cov thev naus laus zis niaj hnub calcination thermal, nws tuaj yeem siv tag nrho lub zog, tshwj xeeb tshaj yog cov roj uas ua rau ib puag ncig ua rau lub zog thiab tig cov khoom pov tseg rau hauv cov khoom muaj nqis. Qhov no tsis tsuas yog tiv thaiv ib puag ncig, tab sis kuj tsim cov khoom zoo thiab cov txiv qaub qis. Nws cov txiaj ntsig ncaj qha thiab tsis ncaj, nyiaj txiag thiab kev sib raug zoo yog qhov tseem ceeb heev. Qhov no yog qhov tseem ceeb ntawm kev nyiam cov thev naus laus zis tshiab txiv qaub kiln.

2. Hom niaj hnub txiv qaub kiln tshuab

Muaj cov sib xyaw kilns los ntawm cov roj, uas yog, cov khoom siv roj, coke, coke hmoov, thee thiab gas kiln. Gas kiln muaj xws li blast furnace gas, coke cub gas, calcium carbide tail gas, furnace gas, natural gas thiab thiaj li nyob. Raws li cov qauv ntawm cov kiln, muaj ncej kiln, rotary kiln, tes tsho kiln, Vimast kiln (West Germany), Melz kiln (Switzerland), Fucas kiln (Ltalis) thiab hais txog. Nyob rau tib lub sijhawm, muaj qhov zoo siab ua haujlwm kiln thiab tsis zoo siab ua haujlwm kiln. Cov niaj hnub sib xyaw kiln nrog 800 cubic meters ib hnub tso zis qis dua 500 thiab cov pa roj niaj hnub nrog 250 cubic meters, tshwj xeeb tshaj yog lub zog txuag thiab kev tiv thaiv ib puag ncig cov txiv qaub kiln nrog blast furnace gas thiab coke cub combustion, tau tsim thiab tsim. Kev tsim thiab tsim khoom ntawm "cov txiv qaub kiln ntev nplaim taws" tau daws qhov teeb meem kub ntawm cov nqi calorific siab thiab luv luv ntawm cov roj coke cub, uas tuaj yeem siv tag nrho cov roj coke qhov cub. Los ntawm thawj coke cub roj "teeb ​​pom kev", ua paug ib puag ncig rau hauv lub zog muaj txiaj ntsig rau cov lag luam los tsim cov txiaj ntsig. Rau cov lag luam me thiab nruab nrab ntawm cov hlau thiab hlau, cov tuam txhab coking, cov tuam txhab calcium carbide, thiab kev lag luam refractory yog qhov zoo heev ntawm kev txuag hluav taws xob, kev tiv thaiv ib puag ncig, kev ua haujlwm zoo thiab kev ua haujlwm zoo.

3.Txoj hauv paus ntsiab lus thiab cov txheej txheem thev naus laus zis

Lub ntsiab ntawm limestone yog calcium carbonate, thaum lub ntsiab ntawm cov txiv qaub yog calcium oxide. Lub hauv paus ntsiab lus ntawm kev hlawv cov txiv qaub yog decompose calcium carbonate hauv limestone rau hauv cov kua qaub ntawm calcium oxide thiab carbon dioxide nrog kev pab los ntawm kub. Nws cov tshuaj tiv thaiv mis yog

CaCO 2 CaO CO 2 – 42.5 KcaI

Nws cov txheej txheem yog cov limestone thiab roj yog preheated nyob rau hauv txiv qaub kilns (yog hais tias roj kav thiab burners yog pub) thiab decarbonized ntawm 850 degrees, calcined ntawm 1200 degrees, ces txias thiab unloaded tawm ntawm lub kiln. Nws cov txheej txheem calcination tag nrho yog sib npaug rau hauv lub thawv ntim khoom. Cov duab sib txawv ntawm qhov cub muaj qhov sib txawv ua ntej, calcination, txias thiab cov hmoov tshauv tshem tawm txoj kev. Txawm li cas los xij, qee cov txheej txheem txheej txheem yog tib yam: calcination kub yog 850-1200 degrees, preheating kub yog 100-850 degrees. Cov tshauv kub yog qis dua 100 degrees. Cov khoom siv raw zoo siab, cov txiv qaub zoo yog qhov zoo; roj calorific nqi yog siab, qhov ntau npaum yog me me; lub limestone particle loj yog proportional rau lub sij hawm calcination; Qhov kev ua haujlwm nrawm nrawm yog qhov sib npaug ntawm lub sijhawm calcination thiab qhov kub ntawm calcination.
