Lub qhov cub semi-qhuav kev tshem tawm cov roj thev naus laus zis yog cov thev naus laus zis roj flue desulfurization rau cov boilers nrog lub peev xwm ntawm 35T / H ~ 670T / H, thiab qhov ua tau zoo desulfurization tuaj yeem ncav cuag ntau dua 85%.
Kev siv tshuaj tsuag ziab yog ib txoj kev siv tshuab FGD tshiab. Piv nrog rau cov txheej txheem ntub, nws cov peev txheej pib tsawg, tab sis cov desulfurizer ntau, yog li nws feem ntau siv rau hauv cov thee sulfur nruab nrab thiab qis (
Kev tsuag kom qhuav kev siv tshuab desulfurization siv lub hauv paus ntsiab lus ntawm kev tsuag kom qhuav kom ua tiav lub hom phiaj ntawm kev tshem tawm cov pa roj flueCov txheej txheem desulfurization ntawm cov tshuaj tsuag kom qhuav yog muab faib ua 5 kauj ruam: (1) kev npaj cov khoom nqus; (2) kev ua kom cov dej nqus tau; (3) kev sib cuag thiab kev sib tov ntawm cov dej ntws thiab cov pa roj flue; (4) kev nqus cov pa roj sulfur dioxide; (5) kev tshem tawm cov khib nyiab pov tseg, thiab peb kauj ruam 2, 3 thiab 4 yog ua tiav hauv lub pej thuam nqus tshuaj tsuag.
Thaum cov atomized slurry kov cov pa roj flue hauv lub pej thuam nqus, cov absorbent pib evaporate, cov pa roj flue txias thiab humidified, thiab cov lime slurry reacts nrog SO2 los ua cov hmoov qhuav. Tag nrho cov tshuaj tiv thaiv yog muab faib ua: SO2 yog nqus los ntawm cov tee dej los tsim calcium sulfite, uas crystallizes tom qab ncav cuag saturation; CaSO3 nyob rau hauv ib feem ntawm cov tshuaj reacts nrog cov pa oxygen yaj hauv cov tee dej kom oxidize rau hauv calcium sulfate, uas crystallizes tawm. Raws li cov calcium hydroxide yaj raug noj thaum lub sijhawm desulfurization txheej txheem, ntau calcium hydroxide solids raug yaj ntxiv kom khaws cov sulfur dioxide tshem tawm cov tshuaj tiv thaiv mus ntxiv.
Hais txog kev ziab cov tee dej thiab cov txheej txheem txias thiab ua kom cov pa roj flue. Kev ziab cov tee dej feem ntau muab faib ua ob theem: theem ib yog qhov dej ntws dawb ntawm qhov chaw ntawm cov tee dej vim tias cov khoom khov hauv cov tee dej slurry tsis loj, thiab qhov ceev ntawm kev ua kom qhuav yog ceev thiab ruaj khov. Thaum cov dej ntws, cov khoom khov ntawm cov tee dej nce ntxiv, thiab theem ob tshwm sim thaum cov khoom khov loj tshwm sim ntawm qhov chaw ntawm cov tee dej. Thaum thaj chaw ntawm qhov chaw ua kom qhuav me dua, cov dej noo yuav tsum kis mus rau sab hauv ntawm cov khoom me me los ntawm cov khoom khov, qhov ceev ntawm kev ziab txo qis, qhov kub ntawm cov tee dej nce ntxiv thiab mus txog qhov kub ntawm cov pa roj flue, thiab thaum kawg sib cais los ntawm cov pa roj flue vim yog kev ua kom qhuav ntawm cov dej hauv kom tsim cov khoom khov.
Lub sijhawm uas cov tee dej yuav tsum qhuav txij thaum pib ua pa yog qhov tseem ceeb heev rau ob qho tib si kev tsim ntawm lub absorber thiab tus nqi desulfurization. Cov yam ntxwv uas cuam tshuam rau lub sijhawm ziab tee dej yog qhov loj ntawm tee dej, cov dej hauv tee dej, thiab qhov kub thiab txias mus rau qhov saturation adiabatic.
