Yuav ua li cas daws qhov tshwm sim ntawm nodulation nyob rau hauv lub teb kiln?

1, Cov nodule tshwm sim tau muab faib ua kiln nodule, annular nodule, thiab kiln phab ntsa nodule
1. Limestone tuaj yeem tsim qee yam impurities thaum lub sijhawm tsim khoom. Yog tias cov impurities no tsis raug tswj kom zoo nyob rau hauv lub qhov cub tawg, lub kiln yuav raug thaiv, yog li lub kiln yuav tsum tau ntxuav thiab khaws cia thaum siv. Tsis txhob sib sau ntau cov impurities hauv qhov cub.
2. Kev sib xyaw ua ke ntawm cov thee ntau dhau thiab qhov concentration ntawm cov nqi hluav taws xob ua rau lub zog kub hauv zos, ua rau lub luag haujlwm ntawm cov hmoov tshauv. Cov roj hnyav yog atomized los ntawm cov cuab yeej tshuaj tsuag, thiab thaj chaw saum npoo av nce ntxiv. Cov roj tee yog preheated los ntawm hluav taws xob thiab convection cua sov hloov ntawm cov phab ntsa ntawm lub cub tawg thiab sab hauv lub cub tawg, evaporated los ntawm qhov chaw, thiab combusted los ntawm diffusion ntawm ib puag ncig huab cua.
3. Kev mob siab ua haujlwm, tso tawm lub sijhawm ncua ntev dhau, tsis tuaj yeem kuaj xyuas kev tuaj koom thiab pub mis cog qoob loo;. Lub crosswind muaj zog thiab ceev ceev, nrog rau qhov cua tsis zoo nyob rau hauv nruab nrab. Qhov kub ntawm thaj tsam calcination yog qhov yuav tsum tau ua ua ntej rau nodulation. Yog tias qhov kub ntawm lub kiln tsis tuaj yeem tswj tau zoo thaum lub sijhawm tua hluav taws, teeb meem loj yuav tshwm sim hauv qhov cub. Piv txwv li, yog tias qhov cub hlawv thaum siv, qhov zoo ntawm cov txiv qaub nws tus kheej yuav raug cuam tshuam.
4. Qhov thib ob, kev sib txuas ntau dhau yuav ua rau cov khoom siv hauv qab ntawm cov khoom siv hauv lub qhov cub ua kom yooj yim dua los ua kua thiab ua raws li cov phab ntsa sab hauv ntawm lub kiln. Qhov teeb meem ntawm nodulation nyob rau hauv lub kiln kuj yuav hnyav dua.
2, Kom paub txog qhov ua rau cov kab mob rotary kiln tuberculosis, muaj ob txoj kev tiv thaiv.
1. nruj me ntsis tswj cov inlet zoo tus qauv ntawm raw limestone yog ib qho ntawm cov kev ntsuas tseem ceeb los tiv thaiv cov tsim ntawm nodules nyob rau hauv rotary kilns. Cov ntsiab lus ntawm CaCO3 hauv limestone txawv ntawm qhov chaw mus rau qhov chaw, thiab yuav tsum tau tswj ntau dua 98 feem pua, feem ntau nyob ib ncig ntawm 90 feem pua, thiab qee qhov ntawm 85 feem pua. Vim tias cov chaw tsim khoom tsis paub meej ntawm limestone raw cov ntaub ntawv thiab cov khoom tsis ruaj khov ntawm cov khoom siv raw, qhov zoo ntawm limestone yuav tsum tau tswj nruj me ntsis, thiab kev tshuaj xyuas tsis tu ncua yuav tsum tau ua kom ntseeg tau tias cov limestone ua tau raws li cov qauv.
2. Txhim khu kev ua haujlwm thiab kev tswj cov txheej txheem rotary kiln. Txhawm rau kom muaj kev ruaj ntseg ntawm cov cuab yeej ua haujlwm, nws yog ib qho tsim nyog yuav tsum tau ntxiv dag zog rau kev cob qhia cov neeg ua haujlwm thiab txuas ntxiv txhim kho qhov tseeb ntawm kev ua haujlwm. Kiln tshauv yog coj mus kuaj tsis tu ncua, thiab tus thawj combustion tus nqi yog tswj nyob rau hauv 5 feem pua, nrog CaO tshaj 90 feem pua. Kev ua haujlwm yuav tsum tsis pub tsawg dua 380ml. Raws li qhov zoo ntawm cov txiv qaub tiav, ib qho kev hloov kho tau ua rau qee qhov tseem ceeb ntawm cov khoom siv.
Hauv cov ntsiab lus, muaj peb hom nodulation nyob rau hauv rotary kilns, thiab cov laj thawj rau txhua qhov tshwm sim txawv. Yog li ntawd, thaum ua kev tiv thaiv thiab kev tswj hwm, peb yuav tsum nkag siab txog cov laj thawj txhawm rau txhawm rau daws lawv raws li lub hom phiaj, thiab ua haujlwm zoo hauv kev tiv thaiv kev ua haujlwm kom ntseeg tau tias siv cov cuab yeej siv.
