Cov pa phem hauv tsev
Thaum ntxov li ntawm xyoo pua hauv lub xyoo tas los 60 lub chaw muaj pa paug nyob hauv tsev twb tau tshwm sim, nrog rau kev txhim kho tus neeg nyob ua ke, kev lag luam kho kom zoo dua tuaj, qhov teeb meem ntawm cov huab cua phem hauv tsev tuaj yeem ua ntau dua. Tib neeg muaj 90% ntawm lub sijhawm nyob thiab ua haujlwm hauv tsev, uas yog li 60% ntawm lub sijhawm nyob hauv tsev. Raws li kev soj ntsuam ntawm cov koom haum thoob ntiaj teb, muaj li 2,8 lab cov neeg tuag ncaj qha los yog tsis ncaj los ntawm qhov chaw ua kom muaj paug thoob ntiaj teb txhua xyoo, 30% tshiab thiab rov kho vaj tse hauv lub ntiaj teb muaj cov pa phem hauv tsev uas tsim kev puas tsuaj rau kev noj qab haus huv, nws yog ntau thiab tseem ceeb tshaj rau kev lim piam hauv vaj hauv tsev. Cov pa roj carbon dioxide yog ib hom kev pleev zoo tshaj plaws, muaj qhov zoo tshaj tawm adsorption rau cov pa phem sab hauv.
Cov pa phem sab hauv tsev thiab lawv cov chaw
Pollutant | Tau qhov twg los |
Aerosol | combustion, haus luam yeeb, neeg lub cev |
Asbestus | tshav kub insulating cov ntaub ntawv |
Formaldehyde | cov khoom siv hauv tsev, rooj tog |
CO | combustion, haus luam yeeb |
Microorganism | tsiaj txhu, neeg lub cev |
Ozone | niaj hnub khoom siv hauv chaw ua hauj lwm |
Haus luam yeeb haus luam yeeb | haus luam yeeb |
Radon | phab ntsa thiab lub hauv paus |
VOCS | xim, ntxuav cov neeg ua haujlwm, cov ntaub ntawv hauv tsev |
CO2 | combustion, ua pa |
Allergens | tsiaj, plaub hau, kab, paj ntoos |
Ammonia | antifreezer |
Benzene series | hnyav, polyester fiber, nplaum daim kab xev, nplaum, ntawv tha xim, xim, ntaub pua plag |
Cov paib ntawm cov paib
Kev faib tawm | micropore | nruab nrab-qhov | qhov loj |
Aperture nm | <> | 2.0 ~ 50 | > 50 |
Cua Purification Activated Car yog ua los ntawm ntoo, thee los yog txiv maj phaub plhaub, phom los yog cylindrical tsos. Rau huab cua purification, qhov zoo tshaj plaws yog txiv maj phaub plhaub .
Cov txheej txheem adsorption ntawm cov roj carbon dej kub
Cov yam ntxwv adsorption ntawm cov pa roj carbon ntau yog nyob ntawm seb nws cov pore cov khoom thiab cov khoom siv deg ntom ntws, thiab cov khoom siv deg ntom ntom tshuaj pom cov chemical adsorption ntawm cov pa. Cov pa roj carbon dioxide ua rau muaj adsorption lub cev thiab tshuaj adsorption, feem ntau yog ob qho tib si tau nrog los ntawm kev sib txig sib luag. Lub cev adsorption ntawm tsuas yog cov kev pom zoo ntawm lub zog ntawm cov adsorbs adsorate nyob rau ntawm cov adsorbent. Lub cev adsorption yog rov ua dua, txo cov adsorbent ib nrab siab nyob rau theem roj, nce qhov kev kubsiab adsorption, adsorbent ceev nrooj, tsis hloov nws cov tshuaj muaj pes tsawg leeg. Kev nqus tshuaj lom neeg muaj qhov siab xaiv, thiab ib hom ntawm cov adsorbent tsuas muaj cov nyhuv rau cov khoom tshwj xeeb. Tshuaj lom neeg adsorption yog irreversible, tom qab adsorption adsorbent hloov cov thawj yam ntxwv.
Qhov txawv ntawm lub cev adsorption thiab tshuaj adsorption
Lub Cev Adsorption | Tshuaj Adsorption | |
Adsorption Kub | Yuav tsis nyob deb tshaj lub npev ntawm cov adsorbate | Tsis muaj kev sib txuas nrog lub npau npau ntawm cov adsorbate |
Adsorption Tus Nqi | Tsis tas yuav tsum muaj zog ua kom muaj zog, adsorption tus nqi yog siab heev | Adsorption tus nqi cuam tshuam los ntawm kev ua kom lub zog thiab kub hauv ntau qhov dav |
Selectivity | Tsis xaiv | Muaj zog xaiv |
Adsorption txujci | Multimolecular txheej adsorption | Monomolecular txheej adsorption |
Daim ntawv thov
Cua purification activated carbon muaj zog ntau thaj tsam, ntau pore qauv, high mechanical zog, muaj zog adsorption peev, yooj yim regeneration. Nws muaj peev xwm siv tau cov tshuaj methanol, ammonia, radon, benzene, xylene, pa ua pa, lampblack, tshwj xeeb tshaj yog aromatic compound.
Siv dav rau kev ua kom muaj carbon dioxide, hydrogen, nitrogen, chloride hydride, ethyne, ethylene, cracking gas, inert gases, atomic equipment; Raws li qhov ntim ntawm antigas daim npog qhov ncauj, tshuaj lom roj lim; Rau kev xa tawm cov pa paug thiab cov lim dej kom huv si.
