VOC thiab cua purifier hauv tsev

Yuav luag txhua tus paub txog "tus phooj ywg qub" ntawm smog hauv huab cua. Tab sis hais txog huab cua muaj kuab paug, koj tsuas paub cov teeb meem xws li PM2.5, tab sis koj puas paub tias VOC yog dab tsi?

VOC (Volatile Organic Compounds), uas yog, volatile organic compounds, kom meej, muaj ob hom lus hais txog VOC: ib qho yog VOC nyob rau hauv lub ntsiab lus zoo tib yam, uas tsuas yog piav txog dab tsi yog volatile organic compound, los yog volatile nyob rau hauv dab tsi tej yam kev mob Organic teeb meem; tab sis los ntawm qhov kev xav ntawm kev tiv thaiv ib puag ncig, nws hais txog hom kev ua kom muaj zog ntawm cov organic teeb meem, uas yog, hom volatile organic teeb meem uas tuaj yeem tsim kev puas tsuaj.

VOC yog ib qho tseem ceeb precursors rau PM2.5. Sab nraum VOC feem ntau yog los ntawm alkanes, alkenes, aromatics, aldehydes thiab ketones uas ua los ntawm cov roj combustion thiab lub tsheb tso; thaum nyob sab hauv VOC los ntawm kev hlawv cov thee thiab cov nkev ntuj. Xws li cov khoom combustion, cov pa luam yeeb los ntawm kev haus luam yeeb, cua sov thiab ua noj, kev tsim kho thiab cov khoom siv kho kom zoo nkauj (tshwj xeeb yog cov xim pleev xim, kua nplaum, thiab lwm yam), cov rooj tog zaum, cov khoom siv hauv tsev, cov neeg ua haujlwm tu thiab tawm ntawm tib neeg lub cev.

VOC muaj nyob rau hauv cov huab cua nyob rau hauv daim ntawv ntawm evaporation ntawm ib txwm kub. Nws muaj kev cuam tshuam loj heev rau tib neeg kev noj qab haus huv. Nws toxicity, irritation, carcinogenicity thiab tsw tshwj xeeb yuav cuam tshuam rau ntawm daim tawv nqaij thiab mucous daim nyias nyias thiab ua rau mob hnyav rau tib neeg lub cev. Thiab VOC muaj nyob hauv yuav luag txhua lub ces kaum ntawm peb lub neej. Cov pab pawg tsis muaj zog nyob ib puag ncig peb, xws li cov poj niam cev xeeb tub, cov neeg laus, thiab cov menyuam yaus, muaj zog tiv thaiv huab cua tsis zoo. Yog tias lawv raug cov pa phem ntau dhau mus ntev, lawv yuav ua rau muaj kab mob loj xws li leukemia. Yog li ntawd, ua ntej qhov mob tshwm sim, , Peb yuav tsum ua kom sai li sai tau siv cov pa phem tiv thaiv thiab tswj kev ntsuas.

Txhawm rau tiv thaiv VOC kev puas tsuaj, peb yuav tsum pib los ntawm qhov chaw. Hauv kev kho cov khoom siv khib nyiab, adsorbents xws li cov pa roj carbon activated feem ntau yog siv rau adsorption. Txawm li cas los xij, vim muaj peev xwm adsorption tsawg ntawm cov pa roj carbon activated, ntau cov pa roj carbon activated yog siv rau hauv cov txheej txheem kho. Ib qho me me ntawm cov pa roj carbon activated tuaj yeem hais tias yog ib qho poob rau hauv lub thoob rau kev kho VOC. Txawm li cas los xij, nyob rau xyoo tas los no, vim yog lub teb chaws txoj kev tswj hwm nruj, kev tswj hwm ntawm VOC sab nraum zoov tau txhim kho zoo heev.
