Yuav ua li cas cov pa pa tawm ntawm lub fume hood yuav tsum tau kho?

Organic pov tseg cov pa phem qhov chaw yog dav faib nyob rau hauv cov xwm. Txhawm rau kom tsis txhob muaj pa phem thiab cuam tshuam rau tib neeg kev noj qab haus huv, kev ua kom huv ntawm chav kuaj pa roj yog ib qho teeb meem uas yuav tsum tau daws kom raws sijhawm. Nyob rau hauv cov txheej txheem tsim khoom tiag tiag, ntxiv rau kev txo cov roj noj thiab kev siv cov kuab tshuaj organic, nrog rau kev txo cov tiam thiab emissions ntawm cov pa roj carbon monoxide, peb feem ntau siv cov pa roj cua kev kho mob xws li adsorption, catalytic combustion, low-temperature plasma treatment, Kev kho photocatalytic, thiab lwm yam. Xaiv cov nqi qis, tsis muaj zog, thiab tsis muaj kev ua qias tuaj thib ob hauv kev kho cov pa roj raws li cov xwm txheej tshwj xeeb xws li tso pa roj ntau thiab muaj pes tsawg leeg. Feem ntau, kev lag luam petrochemical siv cov txheej txheem xws li condensation, nqus, thiab ncaj combustion.

1. Condensation method: Cov khoom siv hluav taws xob tsim hluav taws xob tau ncaj qha mus rau hauv cov kev daws teeb meem, thiab cov txiaj ntsig ntawm cov organic tuaj yeem rov qab los ntawm lub condenser nrog adsorption, nqus, thiab phaj sib cais. Cov txheej txheem no yog tsim rau siab concentration, low-temperature organic pov tseg gas, thiab yuav tsum tau txhawb nqa cov khoom siv tub yees nyob rau hauv cov dej tsis txaus.
2. Txoj kev nqus dej: Kev siv dav dav ntawm lub cev nqus dej suav nrog kev ua kom huv ntawm cov pa tso pa tawm ntawm cov kua nqus dej, cua sov tom qab saturation ntawm cov kua nqus dej, rov qab los ntawm cov dej condensed, thiab kev ntsuam xyuas roj; Txoj kev no siv tau rau qhov kub thiab txias tsis tshua muaj siab, tab sis yuav tsum muaj kev teeb tsa ntawm thermal tsom xam rov qab cov cuab yeej, cov khoom ntim loj, thiab kev nqis peev siab.
Activated carbon adsorption feem ntau yog siv los adsorb pa pa. Tom qab adsorption saturation, activated carbon yog regenerated, tso pa tawm, thiab catalytic combustion converts nws mus rau hauv cov khoom tsis muaj teeb meem. Cov regenerated activated carbon yog siv tas li. Tom qab qee qhov kev tsim kho tshiab, lub peev xwm adsorption ntawm cov pa roj carbon activated txo qis, thiab cov pa roj carbon activated yuav tsum tau rov tsim dua lossis hloov.
3. Activated carbon adsorption tam sim no yog ib txoj hauv kev siv los kho cov pa roj carbon monoxide pov tseg. Cov pa roj carbon activated muaj qhov ua tau zoo adsorption rau benzene khib nyiab roj, tab sis tsis muaj peev xwm adsorption rau hydrocarbon pov tseg roj. Qhov tsis zoo ntawm cov pa roj carbon activated adsorption thaum siv yog qhov kev khiav hauj lwm tus nqi siab thiab nws tsis haum rau siv nyob rau hauv qhov chaw ntub dej. Cov pa roj carbon activated feem ntau muaj cov pa roj carbon activated thiab activated carbon fibers. Tus nqi ntawm cov pa roj carbon activated yog pheej yig, tab sis cov nyhuv tsis zoo. Piv nrog activated carbon fiber, activated carbon muaj tus nqi siab dua thiab kev ua tau zoo dua.
4. Direct combustion method: siv cov roj los yog roj ua cov roj pab rau combustion, cua sov cov roj sib xyaw, thiab decomposing high-temperature teeb meem tshuaj mus rau hauv cov khoom tsis zoo; Txoj kev no muaj cov txheej txheem cov cuab yeej siv yooj yim, kev nqis peev tsawg, thiab cov pa roj purification zoo.
5. Catalytic combustion txoj kev: cua sov tso pa roj los ntawm catalytic combustion los hloov tsis muaj teeb meem thiab tsw ntxhiab carbon dioxide thiab dej; Txoj kev no muaj qhov zoo ntawm qhov kub tsis tshua muaj hluav taws xob, txuag hluav taws xob, siab purification tus nqi, kev ua haujlwm yooj yim, me me hneev taw, loj peev, thiab tsim nyog rau qhov kub thiab txias lossis siab concentration organic pov tseg roj.
