Cov ntses noj zaub mov hloov cov khoom siv dej hauv dej, nrog rau qee cov ntses me me thiab cws, ua cov ntses noj zaub mov uas siv ntau yam txuj ci, suav nrog cov cua kub cua kub, nias, ziab, thiab crushing. Malodorous gas yog tsim los ntawm ntau lub ntsiab lus hauv cov txheej txheem tsim khoom, thiab cov ntxhiab tsw phem ua rau huab cua phem heev.
1.Speb cov ntxhiab tsw gas
Kev siv tshuab ua ntses noj hauv kuv lub teb chaws feem ntau yog: cov khoom siv dej khib nyiab, ntub kom qhuav, pulverization,tshuab ziab khaub ncaws, thiab ua ntses noj.
Thawj yam uas ua rau muaj ntxhiab tsw yog:
1) Organized emission sources, xws liua noj kub tso pa tawm los ntawmntses mael ntub ziab rauv;
2) Cov khoom siv hluav taws xob tsis sib haum, xws li cov khoom siv raw khoom, cov dej khib nyiab, cov chaw kho dej khib nyiab, cov khoom siv hloov pauv hauv kev tsim khoom, thiab lwm yam. Lub ntsiab qhov chaw ntawm cov ntxhiab ntawm lawv yog cov kub kub ua noj, cov khoom siv raw cov ntaub ntawv, thiab cov khoom siv raw khoom.
2.Txoj kev xaiv txoj kev
Muaj ntau txoj hauv kev purification rau malodorous gas, feem ntau suav nrog cov hauv qab no:
1)Masking method (neutralization method, odor elimination method): Cov roj malodorous yog tov rau hauv cov scented sib tov los npog qhov tsw.
2)Huab cua oxidation (combustion) txoj kev: siv cov tshuaj tsw qab feem ntau nrog txo cov yam ntxwv, xws li cov organic sulfur thiab organic amines, los ua oxidative deodorization. Muaj cov thermal oxidation thiab catalytic combustion.
3)Txoj kev txau dej: Dissolving malodorous gas nrog dej kom tshem tawm malodorous tsw.
4)Kev siv tshuaj oxidation absorption: qiv cov tshuaj siv tshuaj ua haujlwm txoj kev xav, nws yog qhov tsim nyog rau kev kho cov roj khib nyiab nrog siab concentration ntawm malodorous pollutants, nrog cov thev naus laus zis, kev lag luam ruaj khov thiab cov hneev taw me me, kev ua haujlwm siab dua.
5)Txoj kev adsorption: Cov tshuaj tsw qab yog adsorbed los ntawm adsorbent activated carbon, activated av nplaum, thiab lwm yam, nrog rau siab deodorization efficiency thiab tsawg zog noj.
6)Photocatalytic oxidation txoj kev: Nyob rau hauv irradiation ntawm high-zog ultraviolet lub teeb, ntau yam tshuaj tiv thaiv (photochemical cov tshuaj tiv thaiv) xws li lub nplhaib qhib thiab rhuav cov tshuaj bonds ntawm volatile organic tebchaw (VOCs) degraded mus rau hauv tsawg molecular compounds xws li CO2 thiab H2O; ntawm ib sab, lub teeb hluav taws xob siab ultraviolet yog siv. Cov pa oxygen hauv huab cua yog irradiated los ntawm lub teeb los tsim ozone, ozone absorbs ultraviolet rays los tsim oxygen dawb radicals thiab oxygen, thiab oxygen dawb radicals reacts nrog dej vapor nyob rau hauv cov huab cua los tsim hydroxyl dawb radicals, muaj zog oxidant, thiab organic Cov pa roj yog tag nrho oxidized rau inorganic tshuaj xws li dej thiab carbon dioxide. Tsis tas li ntawd, ozone uas tsis nqus ultraviolet rays kuj yog ib qho muaj zog oxidant, thiab tom qab kev sib cuag nrog qee cov organic pov tseg, nws oxidizes los tsim cov tshuaj inorganic xws li dej thiab carbon dioxide.
7)Kev sib xyaw ua ke: Thaum cov kev xav tau deodorization siab siab thiab nws nyuaj rau ua kom tau raws li qhov yuav tsum tau ua nrog tib txoj kev ua kom huv si, siv txoj kev deodorization ua ke, uas yog, ntau txoj hauv kev siv los ua ke los txhim kho cov deodorization efficiency thiab txo cov nqi khiav lag luam.
Xaiv cov txheej txheem photocatalytic deodorization. Cov ntses pluas noj cov pa tawm yog rub tawm los ntawm cov kiv cua induced, thiab nkag mus rau hauv cov plua plav tshem tawm,Cov khoom siv cua txias thiab dehumidificationlos ntawm cov plua plav hood yeeb nkab rau pretreatment, thiab ces nkag mus rau hauvphotocatalytic deodorization khoom.Tom qab kev kho mob, nws tuaj yeem ncav cuag qhov kev tso tawm tsim nyog.
Tom qab txau cov dej txias ntau ntau, feem ntau ntawm cov txheej txheem kub kub ntawm Fanxiang cov cuab yeej yog condensed thiab xa mus rau lub deodorization ntauwd, thiab cov hmoov av sib xyaw hauv chav dej kuj raug ntxuav. Tom qab ntawd nws raug xa mus rau lub lim dej dehumidifying rau ziab hauv qab lub tshuab nqus tsev. Thaum kawg, lub chav yog hloov mus rau ib qhoion photocatalytic purifier, qhov twg ion thiab UV lub teeb raj siv los rhuav tshem cov ntxhiab tsw molecules, nqa cov chav mus rau cov qauv emission.
