Photochemical oxidation technology ntawm Lub Rooj Muag Tshuaj

Photochemical oxidation tshuab siv lub teeb excitation oxidation los ua O2, H2O2 thiab lwm cov oxidants nrog cov teeb hluav taws xob. Lub teeb uas siv tau yog UV teeb, xws li uv-H2O2, uv-O2 thiab lwm yam kev ua haujlwm, thiab tuaj yeem siv los kho VOCs, ntxhiab, thiab lwm yam tshuaj muaj zog-rau-degrade.

Tus qauv tsim

GB16297-1996

Tsim ntau yam

Nws siv cov pa tawm ntawm nws lub rooj muag xim ua nws lub ciam teb, nrog rau tus txheej txheem tsim, cov khoom siv, hluav taws xob thiab kev kub siab.

Photocatalytic Catalysis Tshuab

Photo-Oxygen Catalysis

Photochemical oxidation tshuab siv lub teeb excitation oxidation los ua O2, H2O2 thiab lwm cov oxidants nrog cov teeb hluav taws xob. Lub teeb uas siv tau yog UV teeb, xws li uv-H2O2, uv-O2 thiab lwm yam kev ua haujlwm, thiab tuaj yeem siv los kho VOCs, ntxhiab, thiab lwm yam tshuaj muaj zog-rau-degrade.

Tsis tas li ntawd, nyob rau hauv lub system nrog ultraviolet lub teeb, muaj ib qhov kev txuam ntawm ultraviolet lub teeb thiab cov hlau ion, uas zoo heev accelerates tus nqi ntawm decomposition ntawm H2O2 los tsim hydroxyl radicals, thiab txhawb nqa qhov oxidation thiab tshem tawm cov organic tshuaj.

Qhov sib txawv ntawm qhov kev yees duab ntawm cov tshuaj yeeb dej tshuaj yog qhov tshuaj lom neeg cov tshuaj tiv thaiv uas tsuas yog ua rau hauv qhov kev txiav txim ntawm lub teeb. Nyob rau hauv cov tshuaj tiv thaiv no, lub teeb zog absorbed los ntawm lub molecule yog siab rau lub xeev siab zog, thiab ces tus electronically zoo siab molecule reacts sib.

Photochemical oxidation yuav siv cov n-type semiconductors ua catalysts, TiO2 vim cov chemical thiab photochemical cov khoom muaj ruaj khov heev, qhov haum tus nqi yog qhov muaj zog tshaj, thiab tsis-cov tshuaj lom neeg pheej yig, tsim nyog, yog li photocatalytic redox tshem tawm cov pa phem feem ntau yog TiO2 ua teeb ci catalyst . Lub tshuab hluav taws xob ntawm photocatalyst oxidation yog tsuas yog tias cov catalyst yog irradiated nrog lub teeb, absorbs lub zog, undergoes electron hloov, generates "electron-qhov" khub, ncaj qha oxidizes thiab txo cov pa paug adsorbed nyob rau saum npoo, los yog oxidizes lub adsorbed hydroxyl OH- nyob rau ntawm qhov chaw. Qhov muaj zog oxidizing hydroxyl radical OH yog ua rau oxidize cov kab mob.

Los ntawm Cov Pa Hauv Ntshav:

Tsheb nrag yog qhov feem ntau qhov ntawm "peb qhov chaw" nyob rau hauv txoj kev tsim lub tsheb. Cov pa roj carbon dioxide yog qhov tseem ceeb ntawm qhov "three wastes" .Tau vim cov neeg tsis muaj kev paub txog cov pa hluav taws, kev siv cov tshuab ua kom tsis muaj roj yog tsis paub tab, thiab cov nqi kho mob nkev yog siab, cov pa nkev feem ntau raug rho tawm tsis muaj kev kho mob.

Cov pa roj cua no yog tso tawm rau hauv qhov chaw uas tsis muaj kev kho mob, thiab qee yam kev mob, yuav ua kom muaj teeb meem duab thaij, muaj feem xyuam rau qhov zoo ntawm qhov chaw, cuam tshuam kev loj hlob ntawm cov tsiaj thiab nroj tsuag thiab tib neeg kev noj qab haus huv. Qee qhov mob VOC exhausts yog crippled, teratogenic, thiab carcinogenic thiab ua rau neeg raug mob loj rau cov tib neeg raug lawv mus ntev heev.

Rau qhov kawg no, ntau lub teb chaws tau tsim cov cai thiab cov cai tswj kom txo tau cov pa roj carbon cua. Tuam Tshoj tus qauv kev tso tawm huab cua rau huab cua phem, GB 16297, tshaj tawm thiab ua raws hauv xyoo 1997, txwv cov pa tawm ntawm 33 kev lim piam, xws li benzene thiab toluene. Lub cev ntim cov organic (VOC) txau cov txheej txheem xws li xylene thiab li ntawm kev txau, sib zog, thiab ziab, txhua tus muaj VOC emissions. Tus nqi ntawm VOC uas tau ua nyob rau hauv lub txee rau lub thoob, qhov sib tw hauv chav tsev, thiab qhov chaw ntub dej yog 60%, 35%, thiab 5%, feem ntau. Tus nqi ntawm cov kua roj vanish uas ua rau peb cov txheej txheem yog 50%, feem. 20% thiab 30%.

Cov kaus poom loj hauv lub thawv tsuag los yog cov txheej txheem txeem yog VOC thiab xim phom (particles), thiab cov pa paug hauv cov qib theem thiab cov ziab kom qhuav yog VOC. Cov xim muaj hlau nplaum muaj tsawg tshaj plaws (feem ntau yog 10μm), siab viscosity, yooj yim kom sib haum ntawm cov khoom siv, yuav tsum tshem cov xim pleev xim ua ntej purified organic nkev, thiab tom qab ntawd ces tshem cov toluene thiab xylene hauv cov pa tua kom zoo txau chaw nyob. Raws li cov cai ntawm Txoj Cai Kho Kev Noj Qab Haus Huv thiab Kev Noj Qab Haus Huv, thaum lub sij hawm siv cov tshuaj tsuag, chav tsev xim yuav tsum muab hloov nrog cov huab cua, thiab yuav tsum tau qhib cov kev sib hloov ntawm huab cua (0.25 mus 1) m / s.

Lub ntsiab ntawm cov pa cua rau cov tshuaj tsuag tsuag yog cov tshuaj tsis haum rau cov thev dej. Lub ntsiab lus tseem ceeb yog cov muaj ntxhiab hydrocarbons, cawv ethers, thiab ester organic solvents. Vim yog qhov loj ntawm cov pa cua hauv lub rooj muag xim, cov pa roj carbon dioxide yog cov pa roj. Qhov concentration yog qhov tsawg, feem ntau yog 100mg / m3. Tsis tas li ntawd, lub qhov muag ntawm cov tshuaj pleev xim rau lub rooj muag tshuaj feem ntau muaj ib qho me me ntawm cov xim tsis muaj paug, tshwj xeeb tshaj yog cov xim qhuav mist los txuag lub thawv, thiab cov phom xim ntawm cov pa hauv siab, uas yuav ua rau muaj kev khuam siab rau kev kho mob nkev hauv av. kam nrog.

Cov Qauv Kev Tso Dej

Tom qab siv cov pa roj carbon dioxide lawm, nws ua tau raws li cov kev cai ntawm "Cov Txheej Txheem Kev Ruaj Ntseg Rau Cov Pa Cua" (GB16297-1996).

Cov txheej txheem emissions (raws li 15m qhov hluav taws xob). Cov kev kawm theem nrab
