Lub tshuab Raymond limestone ua lub luag haujlwm tseem ceeb hauv kev npaj cov hmoov limestone desulfurized. Qhov zoo ntawm lub tshuab 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 kev siv tshwj xeeb ntawm Raymond limestone sib tsoo tshuab hauv kev desulfurization limestone pulverization.
I. Qhov tseem ceeb ntawm daim ntawv thov ntawm Raymond limestone zeb hauv desulfurized limestone pulverization
Tam sim no, ntau tshaj 90% ntawm cov chaw tsim hluav taws xob thermal hauv Suav teb tau siv cov thev naus laus zis limestone gypsum desulfurization, uas muaj cov thev naus laus zis laus thiab pheej yig. Ob qho txheej txheem xav tau hmoov limestone kom nqus tau sulfur dioxide, thiab qhov me me ntawm cov hmoov limestone yog, qhov ntau dua rau kev nqus ntawm SO2.
II. Cov yam tseem ceeb uas cuam tshuam rau kev ua haujlwm ntawm cov limestone desulfurization
(1) Qhov zoo ntawm limestone
Feem ntau, cov ntsiab lus ntawm CaSO4 hauv limestone yuav tsum siab dua 85%. Yog tias cov ntsiab lus qis dhau, nws yuav coj qee qhov teeb meem rau 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 desulfurization efficiency. Tab sis limestone tsis tas yuav tsum muaj CaO cov ntsiab lus, qhov siab dua qhov zoo dua. Piv txwv li, limestone nrog Cao > 54% yog Dali Petrochemical vim nws qhov huv siab, tsis yooj yim rau kev sib tsoo thiab muaj zog tshuaj lom neeg ruaj khov, yog li nws tsis haum rau siv ua desulfurizer.
(2) Qhov loj ntawm cov pob zeb limestone (qhov zoo)
Qhov loj ntawm cov pob zeb limestone cuam tshuam ncaj qha rau qhov kev ua haujlwm ntawm cov tshuaj. Thaum thaj chaw tshwj xeeb loj dua, qhov kev ua haujlwm ceev dua thiab qhov kev ua haujlwm txaus. Yog li ntawd, feem ntau yuav tsum tau kom cov hmoov limestone hla dhau 250 mesh sieve lossis 325 mesh sieve mus txog 90%.
(3) Cov nyhuv ntawm limestone reactivity rau desulfurization system kev ua tau zoo
Cov limestone uas muaj kev ua haujlwm siab dua tuaj yeem ua tiav qhov kev tshem tawm sulfur dioxide ntau dua nyob rau hauv qhov xwm txheej ntawm kev tswj hwm tib tus nqi siv limestone. Limestone muaj kev ua haujlwm siab, kev siv limestone siab thiab cov ntsiab lus tsawg ntawm CaCO3 ntau dhau hauv gypsum, uas yog, gypsum muaj kev ntshiab siab.
III. Txoj cai ua haujlwm ntawm limestone Raymond zeb
Lub tshuab zeb Raymond limestone muaj cov khoom sib tsoo, kev tshuaj ntsuam xyuas qib, kev sau cov khoom thiab lwm yam khoom. Lub cav tseem ceeb siv cov qauv casting integral, thiab lub hauv paus damping tuaj yeem siv tau. Lub kaw lus faib tawm siv cov qauv ntawm cov turbine classifier, thiab lub kaw lus sau cov khoom siv pulse collection.
(1) Txoj cai ua haujlwm ntawm Raymond limestone zeb
Cov khoom siv raug tsoo ua cov khoom me me uas tsim nyog los ntawm lub puab tsaig crusher, nqa mus rau lub hopper cia khoom los ntawm lub tshuab nqa plua plav, thiab tom qab ntawd xa mus rau lub tshuab loj qhov chaw los ntawm lub tshuab pub rau kev sib tsoo. Lub cav qhov chaw tseem ceeb tau txhawb nqa ntawm lub thav duab paj plum, thiab lub cuab yeej sib tsoo roller tig ib ncig ntawm lub hauv paus. Lub log sib tsoo roller tig kab rov tav sab nraud raws li qhov kev ua ntawm lub zog centrifugal, yog li ntawd lub log sib tsoo roller nias lub nplhaib sib tsoo, thiab lub log sib tsoo roller tig ib ncig ntawm lub log sib tsoo roller tib lub sijhawm. Cov khoom siv uas tau tsa los ntawm cov hniav sib hloov raug pov tseg ntawm lub log sib tsoo roller thiab lub nplhaib sib tsoo kom ua tiav kev ua haujlwm ntawm kev sib tsoo thiab kev sib tsoo vim yog lub log sib tsoo ntawm lub log sib tsoo.
(2) Cov txheej txheem ua haujlwm ntawm Raymond limestone mill thiab separator
Cov hmoov av raug cua tshuab los ntawm cua tshuab mus rau lub tshuab cais saum lub tshuab tseem ceeb rau kev tshuaj ntsuam, thiab cov hmoov zoo thiab ntxhib tseem poob rau hauv lub tshuab tseem ceeb rau kev sib tsoo dua. Yog tias qhov zoo ua tau raws li qhov kev qhia tshwj xeeb, nws ntws mus rau hauv lub tshuab cua daj cua dub nrog cua thiab raug tso tawm los ntawm cov yeeb nkab tso hmoov tom qab sau, uas yog cov khoom tiav (qhov loj me ntawm cov khoom tiav 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, thiab txoj kev cua 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, thiab cov xwm txheej huv hauv tsev zoo.
IV. Cov yam ntxwv ntawm Raymond limestone zeb
Lub tshuab zeb Limestone Raymond uas tsim los ntawm HCMilling (Guilin Hongcheng) yog qhov hloov tshiab txog kev siv tshuab sib tsoo R-hom. Cov ntsuas kev siv tshuab ntawm cov khoom tau zoo dua qub piv rau lub tshuab R-hom. Nws yog hom tshuab sib tsoo tshiab uas muaj kev ua haujlwm zoo thiab txuag hluav taws xob. Qhov zoo ntawm cov khoom tiav tuaj yeem yog 22-180 μ M (80-600 mesh).
(1) (Tshuab Tshiab) lub thav duab paj plum thiab lub tshuab sib tsoo ntsug, nrog cov qauv siab heev thiab tsim nyog. Lub tshuab muaj kev co tsawg heev, suab nrov tsawg, kev ua haujlwm ruaj khov thiab kev ua haujlwm txhim khu kev qha.
(2) Lub peev xwm ua cov khoom siv hauv lub sijhawm sib tsoo ntawm chav tsev 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) Cov cua seem ntawm lub pulverizer yog nruab nrog lub tshuab sau plua plav, thiab nws cov txiaj ntsig sau plua plav ncav cuag 99.9%.
(4) Nws siv cov qauv tsim tshiab, thiab lub cuab yeej sib tsoo menyuam tuaj yeem sau cov roj ib zaug txhua 300-500 teev.
(5) Nws siv cov thev naus laus zis tshwj xeeb uas tsis yooj yim hnav thiab ua los ntawm cov chromium alloy siab, uas tsim nyog dua rau kev sib tsoo thiab dov nrog zaus siab thiab thauj khoom loj, thiab nws lub neej ua haujlwm yuav luag peb npaug ntawm tus qauv kev lag luam.
Piv nrog rau cov tshuab Raymond ib txwm muaj, cov tshuab dov lub tshuab, cov tshuab pob thiab lwm yam txheej txheem, cov tshuab Raymond limestone tuaj yeem txo kev siv hluav taws xob los ntawm 20% ~ 30%, thiab tuaj yeem txhim kho kev npaj cov hmoov limestone desulfurization uas zoo rau ib puag ncig.
