1.1 Txheej txheem cej luam ntawm thee npaj cog
Longquan Coal Plant Plant ntawm Taiyuan Coal Gasification Company yog ib qho loj-scale dual-system nrog tsim peev xwm ntawm 5.00Mt / a uas tsuas yog tsim coking thee thiab coj mus rau hauv tus account cov thermal thee.Lub coarse slime system ntawm cov thee npaj cog nyiaj rau 5% ntawm cov thee raw cov nqi thiab muaj peev xwm ua tiav ib teev ntawm 56.82t / h.
1.2 Txheej txheem sorting
Cov txheej txheem kev npaj cov thee hauv kev tsim cov thee npaj cog yog raws li hauv qab no: Tom qab cov thee raw tau deslimed thiab tshuaj ntsuam (lub desliming screen yog 1 hli), 50 ~ 1 hli yog sib cais los ntawm ib tug desliming thiab pressureless peb-khoom hnyav-nruab nrab cyclone. , 1 ~ 0.25mm Cov coarse coal slime yog sib cais los ntawm TBS, thiab -0.25mm zoo coal slime yog zoo tu qab tso los ntawm thickening thiab lim xovxwm raws li ib tug nruab nrab coal khoom.
2.1 Kev sib cais thiab rov qab txheej txheem ntawm coarse slime ua ntej kev hloov pauv
Kev sib cais thiab rov qab txheej txheem ntawm coarse slime ua ntej kev hloov pauv ntawm Longquan Coal Preparation Plant yog: cyclone concentration + TBS sib cais + cyclone concentration + arc sieve desliming thiab dewatering + centrifuge dewatering.Cov txheej txheem tshwj xeeb yog qhia hauv daim duab 1.

2.2 Muaj teeb meem
Table 1 qhia cov ntaub ntawv sim sieving ntawm cov nkhaus sieve cov tswv yim thiab cov khoom siv dhau ntawm lub vijtsam thaum lub nkhaus sieve tau siv los txiav thiab categorize TBS concentrate overflow ua ntej kev hloov pauv.Los ntawm kev sib piv ntawm cov ntaub ntawv ntsuam xyuas, nws tuaj yeem pom tias qhov sib txawv ntawm cov hmoov tshauv ntawm cov khoom tuaj thiab cov sieve yog tsawg dua 5%, uas qhia tau hais tias qhov kev tshuaj ntsuam xyuas ntawm lub arc sieve yog tsawg thiab cov hmoov tshauv txo. yog neeg pluag heev.
Table 1 Kev tshuaj ntsuam xyuas cov ntaub ntawv ntawm arc sieve ua ntej kev hloov pauv thev naus laus zis
Longquan Coal Preparation Plant muaj cov hmoov tshauv siab, loj gangue sludge, siab hauv cov tshauv, tsis tshua muaj siab tawm los, thiab cov khoom lag luam loj nruab nrab.Yog li ntawd, nyob rau hauv kev xyaum ntau lawm, tus thawj tsim ntawm cov ntxhib slime sib cais thiab rov qab txheej txheem mas muaj cov nram qab no teeb meem:
Cov txheej txheem qub tau txais qhov kev tshuaj ntsuam arc-zoo li qhov kev tshuaj ntsuam qis dua los txiav cov ntxhib, sludge thiab dewater ntws ntawm TBS concentrate.Vim tias qhov tshwm sim ntawm av nkos loj ntawm gangue nyob rau hauv cov thee nyoos thiab cov ntsiab lus siab ntawm cov av tshauv nplua nuj, nws yuav ua rau inevitably ua rau: lub vijtsam nkhaus muaj ntau cov av nkos siab, uas ua rau cov hmoov tshauv siab ntawm cov ntxhib. thiab huv si;lub vijtsam nkhaus siv cov hlau tsis muaj steel Lub qhov screen slotted muaj qhov sib txawv loj ntawm lub vijtsam thiab yog ib qho yooj yim rau hnav, uas yuav ua rau muaj ntau cov hmoov tshauv coarse slime rau stray thiab poob coarse huv si.Nyob rau tib lub sijhawm, lub vijtsam yuav tsum tau hloov ntau zaus.
3.1 Technological transformation plan
Txhawm rau txhim kho tus nqi rov qab ntawm cov thee huv thiab cov txiaj ntsig kev lag luam, Longquan Coal Preparation Plant ua ke nrog Anhui Fangyuan Plastic Co., Ltd. los hloov cov txheej txheem sib cais sib cais.Tom qab ua qauv qhia, nws ncaj qha txais yuav Anhui Fangyuan Plastic Co., Ltd. los tsim kev tshuaj ntsuam xyuas kev ua haujlwm siab, FY-HVS-1500 laminated high-frequency screen nrog cov nyhuv desilting zoo hloov lub vijtsam nkhaus kom ua tau zoo thiab ua tau zoo txiav TBS overflow khoom thiab tshuaj ntsuam. nws.
3.2 Cov qauv thiab txoj hauv kev ua haujlwm ntawm FY-HVS-1500 laminated high zaus screen.
Fangyuan FY-HVS-1500 high-frequency stacked screen yog ib yam ntawm cov cuab yeej siv tshuab uas siv cov kev vibration siab ntawm qhov screen thiab lub ntiajteb txawj nqus ntawm cov khoom kom ua tiav kev faib tawm raws li qhov loj me ntawm cov khoom.Nws cov qauv yog tsuas yog tsim los ntawm tus neeg xa khoom, lub feeder, thiab sab sauv thiab sab npo thav ntawv., High-frequency vibration motor, khoom sau hopper ntawm qhov screen, cov khoom sau tank nyob rau hauv lub vijtsam, ncej thiab txhawb nqa platform.Lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab sieve yog qhia hauv daim duab 2. Nws cov yam ntxwv tseem ceeb thiab qhov zoo yog raws li hauv qab no.
