Kev tshem tawm cov sulfur dioxide los ntawm cov roj flue los ntawm kev ziab kom qhuav, kev siv cov tshuab ziab khaub ncaws desulphurization hauv kev tiv thaiv ib puag ncig ecological, kev tsim nyog thiab kev siv ntau ntawm cov hmoov sulphates.

Kev tshem tawm cov sulfur dioxide los ntawm cov roj flue los ntawm kev ziab kom qhuav, kev siv cov tshuab ziab khaub ncaws desulphurization hauv kev tiv thaiv ib puag ncig ecological, kev tsim nyog thiab kev siv ntau ntawm cov hmoov sulphates.

Abstract:

Ib qho tseem ceeb ua ntej rau kev siv dav dav ntawm cov pos hniav ziab cov pos hniav yog seb nws puas tuaj yeem daws qhov teeb meem ntawm kev tsim kho thiab kev siv cov hmoov sulfate ntau tom qab ziab. Yuav rov tsim dua tshiab raws li kev nqus dej, ib feem ntawm cov khoom siv qhuav tuaj yeem rov ua dua tshiab, raws li lub ntiaj teb ntxiv, hloov mus ua tus neeg sawv cev muab tshuaj siv rau cov cement retarder, ua los ntawm cov khoom siv dag zog granular ...

Raws li lub ntiaj teb kev siv hluav taws xob nce xyoo los ntawm ib xyoos, kev sib xyaw thiab kev siv cov thee ua lub zog tseem ceeb, tso tawm cov sulfur dioxide ntau ntxiv nrog rau kev tsim cov kua qaub hauv cheeb tsam, tau ua rau muaj kuab paug loj rau ib puag ncig, uas cuam tshuam rau cov khoom siv hluav taws xob. ecological tshuav nyiaj li cas, ua rau loj loj kev puas tsuaj ntawm hav zoov, acidification ntawm av thiab pas dej, thiab corrosion ntawm lub tsev.

Yog li ntawd, kev tswj thiab txo cov pa tawm ntawm sulfur dioxide yog ib txoj haujlwm tseem ceeb. Ntawm ntau cov thev naus laus zis desulfurization, kev siv cov tshuaj tsuag kom qhuav kom tshem tawm cov sulfur dioxide los ntawm cov pa hluav taws xob yog ib qho cuab yeej uas tau txais kev saib xyuas ntau dua. Cov thev naus laus zis no tau kawm thawj zaug hauv xyoo 1970 thiab tau muab tso rau hauv kev lag luam thaum xyoo 1970s. Nws muaj peev txheej tsawg dua, kev ua haujlwm yooj yim, kev tshem tawm cov tshuaj sulfur siab, tsis muaj kev ua qias tuaj nruab nrab, thiab piv nrog cov txheej txheem ntub dej uas siv ntau hauv flue gas desulfurization, cov hmoov khoom tsim los ntawm cov tshuaj tsuag kom qhuav txoj kev desulfurization muaj ntau dua xaiv thiab kev loj hlob tus nqi.

Txau tshuab ziab khaub ncaws gel sulfur tuaj yeem siv dav hauv qhov tseem ceeb ua ntej yog seb nws tuaj yeem daws qhov tsim nyog thiab siv ntau cov hmoov sulfate tom qab ziab. Yuav rov tsim dua tshiab raws li kev nqus dej, ib feem ntawm cov khoom qhuav tuaj yeem rov ua dua tshiab, ua cov khoom siv ntxiv rau hauv lub ntiaj teb, hloov mus ua tus neeg sawv cev rau cov cement retardant, ua los ntawm granular dag xuab zeb thiab gravel, ua cov khoom siv hauv tsev es tsis txhob siv ntau. pob zeb thiab asphalt thiab lwm yam.
