Lub tshuab sib tsoo Raymond limestone ua lub luag haujlwm tseem ceeb hauv kev npaj cov hmoov limestone desulfurized. Qhov zoo ntawm lub tshuab sib tsoo Raymond limestone cuam tshuam ncaj qha rau qhov zoo, qhov zoo thiab qhov loj ntawm cov hmoov limestone. Cov hauv qab no yuav piav qhia txog cov yam ntxwv thiab cov ntawv thov tshwj xeeb ntawm lub tshuab sib tsoo Raymond limestone hauv kev sib tsoo limestone desulfurization.

1. Qhov tseem ceeb ntawm daim ntawv thov ntawm Raymond limestone zeb hauv desulfurization limestone hmoov ua

Nag hmo, thawj lub Rooj Sab Laj Txog Kev Ua lej Carbon Neutral ntawm Tuam Tshoj tau muaj nyob rau hauv Chengdu, uas ua rau thoob ntiaj teb saib xyuas "kev txhim kho ntsuab". Raws li Tuam Tshoj yog thawj tus hauv kev tso pa tawm SO2, nws yog qhov tseem ceeb kom tswj hwm cov pa tawm SO2 los ntawm cov lag luam tseem ceeb xws li cov chaw tsim hluav taws xob thermal thiab cov boilers siv thee.

Tam sim no, ntau tshaj 90% ntawm cov chaw tsim hluav taws xob thermal hauv tsev siv cov thev naus laus zis limestone-gypsum desulfurization. Cov thev naus laus zis no laus lawm thiab tus nqi qis. Ob qho txheej txheem xav tau siv cov hmoov limestone los nqus cov sulfur dioxide, thiab qhov me me ntawm cov hmoov limestone, qhov ntau dua nws yog rau kev nqus ntawm SO2.

1. Cov yam tseem ceeb uas cuam tshuam rau kev ua haujlwm ntawm limestone desulfurization

(1) Qhov zoo ntawm limestone

Feem ntau hais lus, cov ntsiab lus CaSO4 hauv limestone yuav tsum siab dua 85%. Yog tias cov ntsiab lus qis dhau, nws yuav ua rau muaj teeb meem hauv kev ua haujlwm vim muaj ntau yam tsis huv. Qhov zoo ntawm limestone yog txiav txim siab los ntawm cov ntsiab lus ntawm CaO. Qhov siab dua qhov huv ntawm limestone, qhov zoo dua qhov ua haujlwm desulfurization. Tab sis limestone tsis tas yuav muaj cov ntsiab lus CaO siab dua, qhov zoo dua. Piv txwv li, limestone nrog CaO> 54% muaj qhov huv siab thiab marble tsis yooj yim rau kev sib tsoo thiab muaj zog tshuaj lom neeg ruaj khov, yog li nws tsis haum rau siv ua tus neeg sawv cev desulfurization.

(2) Qhov loj ntawm cov pob zeb limestone (qhov zoo)

Qhov loj ntawm cov khoom me me ntawm cov pob zeb limestone cuam tshuam ncaj qha rau qhov ceev ntawm cov tshuaj tiv thaiv. Thaum thaj chaw loj dua, qhov ceev ntawm cov tshuaj tiv thaiv sai dua thiab cov tshuaj tiv thaiv tiav dua. Yog li ntawd, cov hmoov limestone uas xav tau feem ntau tuaj yeem hla dhau lub lim dej 250 mesh lossis 325 mesh, thiab qhov nrawm ntawm kev tshuaj ntsuam tuaj yeem ncav cuag 90%.

(3) Cov nyhuv ntawm limestone reactivity rau desulfurization system kev ua tau zoo

Pob zeb limestone uas muaj kev ua haujlwm siab dua tuaj yeem ua tiav qhov kev tshem tawm sulfur dioxide ntau dua thaum tswj hwm tus nqi siv limestone tib yam. Limestone reactivity siab, thiab limestone siv tus nqi kuj siab. CaCO3 ntau dhau hauv gypsum qis, uas yog, qhov huv ntawm gypsum siab.

3. Txoj cai ua haujlwm ntawm Raymond limestone sib tsoo zeb

Lub tshuab sib tsoo pob zeb Raymond limestone muaj cov khoom sib tsoo, kev tshuaj xyuas kev faib tawm, kev sau cov khoom thiab lwm yam khoom. Lub tshuab tseem ceeb siv cov qauv tsim ua ke, uas tuaj yeem siv ua lub hauv paus nqus tau. Lub kaw lus faib tawm siv cov qauv turbine classifier, thiab lub kaw lus sau cov khoom siv pulse collection.

(1) Txoj cai ua haujlwm ntawm Raymond limestone sib tsoo zeb

Cov khoom siv raug tsoo ua ib qho me me uas ua tau raws li cov lus qhia los ntawm lub puab tsaig crusher, nqa mus rau lub hopper cia khoom los ntawm lub thoob nqa, thiab tom qab ntawd pub rau hauv chav loj los ntawm lub feeder rau kev sib tsoo. Lub cuab yeej sib tsoo roller txhawb nqa ntawm lub thav duab paj plum hauv lub tshuab tseem ceeb tig ib ncig ntawm lub axis nruab nrab. Lub log sib tsoo swings kab rov tav sab nraud nyob rau hauv qhov kev ua ntawm lub zog centrifugal, yog li ntawd lub log sib tsoo nias lub nplhaib sib tsoo thiab lub log sib tsoo tig ib ncig ntawm lub log sib tsoo tib lub sijhawm. Cov khoom siv tsa los ntawm cov hniav sib hloov raug pov tseg ntawm lub log sib tsoo thiab lub nplhaib sib tsoo, thiab raug tsoo thiab sib tsoo los ntawm lub log sib tsoo.

(2) Cov txheej txheem ua haujlwm ntawm cov hmoov xaiv ntawm Raymond limestone zeb

Cov hmoov av raug cua tshuab los ntawm cov cua ntawm lub tshuab cua mus rau lub tshuab cais saum lub tshuab tseem ceeb rau kev sib tsoo. Cov hmoov uas zoo thiab ntxhib dhau tseem yuav poob rau hauv lub tshuab tseem ceeb rau kev sib tsoo dua, thiab cov hmoov uas ua tau raws li cov lus qhia yuav ntws mus rau hauv lub tshuab cua daj cua dub nrog cua. Tom qab sau, cov khoom tiav lawm raug tso tawm los ntawm cov yeeb nkab tso hmoov (qhov loj me ntawm cov khoom tiav lawm tuaj yeem siab txog 0.008 hli). Cov cua ntshiab ntws mus rau hauv lub tshuab cua los ntawm cov yeeb nkab ntawm qhov kawg ntawm lub cua daj cua dub. Txoj kev cua tab tom ncig. Tsuas yog lub siab zoo los ntawm lub tshuab cua mus rau chav sib tsoo, cov cua ntws hauv lwm cov kav dej ntws hauv qab lub siab tsis zoo. Cov xwm txheej huv hauv tsev zoo.

4. Cov yam ntxwv ntawm Raymond limestone sib tsoo zeb

Guilin Hongcheng Raymond limestone sib tsoo zeb yog qhov hloov tshiab raws li R-hom sib tsoo zeb. Cov ntsuas kev ua haujlwm ntawm cov khoom no tau zoo dua piv rau tib lub sijhawm ntawm R-hom sib tsoo zeb. Nws yog ib hom khoom sib tsoo zeb tshiab nrog kev ua haujlwm siab thiab txuag hluav taws xob. Qhov zoo ntawm cov khoom tiav tuaj yeem hloov kho tau ntawm 22-180μm (80-600 mesh).

(1) (Tes haujlwaj tshiab) Lub thav duab paj plum thiab lub tshuab sib tsoo ntev muaj cov qauv siab heev thiab tsim nyog. Lub tshuab muaj kev co me me, suab nrov tsawg, kev ua haujlwm yooj yim thiab kev ua haujlwm txhim khu kev qha.

(2) Lub sijhawm ua cov khoom siv rau ib chav sib tsoo loj dua thiab kev ua haujlwm zoo dua. Cov zis tau nce ntau dua 40% txhua xyoo, thiab tus nqi siv hluav taws xob ntawm chav tsev tau txuag tau ntau dua 30%.

(3) Qhov cua tawm ntawm lub tshuab sib tsoo yog nruab nrog lub tshuab sau plua plav, uas nws cov txiaj ntsig sau plua plav ncav cuag 99.9%.

(4) Txais yuav tus qauv tsim tshiab ntawm kev sib khi, lub tshuab sib tsoo tuaj yeem puv nrog roj ib zaug txhua 300-500 teev.

(5) Siv cov thev naus laus zis tshwj xeeb uas tsis yooj yim hnav, nws tsim nyog dua rau kev sib tsoo ntau zaus, kev sib tsoo loj thiab kev dov, thiab lub neej ua haujlwm yuav luag peb zaug ntev dua li tus qauv kev lag luam.

In summary, compared with traditional Raymond mill, suspension roller mill, ball mill and other processes, the use of Raymond limestone mill can reduce energy consumption by 20% to 30%, which can improve the preparation of environmentally friendly desulfurized limestone powder.
