Hauv kev tsim cov roj flue desulfurization nyob rau hauv thermal fais fab nroj tsuag, vim muaj kev cuam tshuam ntawm cov txheej txheem desulfurization thiab flue gas, cov dej khib nyiab muaj ntau cov tshuaj insoluble, xws li calcium chloride, fluorine, mercury ions, magnesium ions thiab lwm yam hlau hnyav. cov ntsiab lus.Thee thiab limestone siv hauv thermal fais fab nroj tsuag tuaj yeem ua rau muaj kuab paug loj rau cov dej khib nyiab.Tam sim no, nyob rau hauv tus txheej txheem ntawm kev txais yuav flue roj desulfurization tshuab nyob rau hauv ib co thermal fais fab nroj tsuag nyob rau hauv kuv lub teb chaws, cov dej khib nyiab generated muaj ntau suspended solids thiab ntau yam hnyav hlau ntsiab, uas yog flue gas desulfurization wastewater.
Qhov zoo ntawm cov dej khib nyiab desulfurization yog txawv ntawm lwm cov dej khib nyiab, thiab muaj cov yam ntxwv ntawm cov turbidity siab, siab salinity, muaj zog corrosiveness thiab yooj yim scaling.Raws li cov cai ntawm kev tiv thaiv ib puag ncig, desulfurization cov dej khib nyiab yuav tsum ua kom tsis muaj paug.Txawm li cas los xij, ib txwm evaporative xoom-emission technologies xws li MVR thiab MED muaj qhov tsis zoo ntawm kev nqis peev siab thiab kev ua haujlwm siab, thiab tsis tuaj yeem siv dav.Yuav ua li cas kom ua tiav "tus nqi qis thiab xoom tso tawm" ntawm cov dej khib nyiab desulfurization tau dhau los ua qhov teeb meem ceev uas yuav tsum tau daws.
Cov khoom siv kho dej khib nyiab desulfurization tuaj yeem maj mam mloog desulfurization cov dej khib nyiab los ntawm cov txheej txheem sib cais xws li Wastout, R-MF pretreatment, HT-NF sib cais, thiab HRLE txwv kev sib cais.Qhov tshwj xeeb membrane sib cais tshuab txais ultra-wide dej inlet channel, high-strength qauv tsim thiab tshwj xeeb membrane ntsiab nrog muaj zog tiv thaiv muaj kuab paug muaj peev xwm, uas ua kom lub sij hawm ntev kev ua hauj lwm ntawm lub system.Cov txheej txheem tsim ua rau nws nyuaj rau tsim ib txheej polarized ntawm daim nyias nyias, thiab muaj zog tiv thaiv kev ua qias tuaj.Kev khiav hauj lwm tus nqi ntawm lub kaw lus yog tsawg, thiab cov nqi khiav hauj lwm ib tuj dej tsuas yog 40-60% ntawm cov txheej txheem ib txwm muaj.
Tau ntev, cov dej khib nyiab desulfurization tau raug tsis quav ntsej los ntawm chav ua haujlwm vim nws tsis yog ib feem ntawm cov tub ntxhais desulfurization system.Los yog xaiv ib qho yooj yim desulfurization cov txheej txheem dej khib nyiab thaum lub sij hawm tsim kho, lossis tsuas yog tshem tawm cov kab ke.Hauv kev ua haujlwm, thermal fais fab nroj tsuag yuav tsum tau qhia meej lub hom phiaj thiab cov kev xav tau ntawm flue gas desulfurization dej khib nyiab, ua kom muaj nuj nqis ntawm kev siv thev naus laus zis, tsim cov phiaj xwm kev tswj hwm lub suab, ua kom muaj txiaj ntsig zoo, txhim kho kev tswj hwm kev ua haujlwm, thiab txhim kho cov txiaj ntsig ntawm kev tshawb fawb thiab thev naus laus zis. kev tshawb fawb thiab kev siv.
