Dilution thiab Diffusion Method
Lub hauv paus ntsiab lus: Cov pa roj tsw qab tau tawm mus rau hauv qhov chaw ntawm lub qhov cub los yog diluted nrog cov ntxhiab tsw cua kom txo tau cov concentration ntawm cov tshuaj malodorous, yog li txo cov ntxhiab tsw.
Scope of Application: Haum rau kev kho cov nruab nrab - mus rau - cov pa roj carbon monoxide tsawg los ntawm cov txheej txheem (ducted) emission sources.
Qhov zoo: Tus nqi qis thiab cov khoom siv yooj yim yuav tsum tau ua.
Disadvantages: Kev kub ntxhov rau huab cua huab cua; cov tshuaj malodorous tseem nyob es tsis raug tshem tawm.
Txoj kev nqus dej
Lub hauv paus ntsiab lus: Siv cov yam ntxwv uas qee yam tshuaj malodorous yog soluble hauv dej; cov roj Cheebtsam raug coj mus rau hauv kev sib cuag nrog dej, dissolving nyob rau hauv kom tiav deodorization.
Scope of Application: Malodorous gases uas yog dej -soluble thiab originate los ntawm lub koom haum emission sources.
Qhov zoo: Cov txheej txheem yooj yim, tswj tau yooj yim, thiab cov cuab yeej siv qis ua haujlwm.
Disadvantages: Tsawg purification efficiency; yuav tsum tau siv nrog rau lwm yam technologies. Nws tsis muaj txiaj ntsig rau cov tshuaj xws li mercaptans thiab fatty acids.
Aeration Deodorization Method
Lub hauv paus ntsiab lus: Cov tshuaj malodorous tau muab faib ua -ntawm aeration- mus rau hauv cov cawv sib xyaw uas muaj cov activated sludge, uas lawv degraded los ntawm cov kab mob uas raug tshem tawm.
Scope of Application: Kev siv dav dav. Raws li xyoo 2013, txoj kev no tau ua tiav hauv Nyij Pooj rau kev tswj cov ntxhiab ntawm cov chaw kho mob thiab cov chaw kho dej phwj.
Qhov zoo: Thaum cov activated sludge tau acclimated, tshem tawm tus nqi rau malodorous Cheebtsam - muab lawv tsis pub dhau lub kaw lus load txwv - tuaj yeem ncav cuag tshaj 99.5%.
Disadvantages: Daim ntawv thov ntawm txoj kev no yog me ntsis txwv los ntawm kev txwv ntawm aeration siv.
Catalytic Oxidation txheej txheem
Lub hauv paus ntsiab lus: Cov tshuaj tiv thaiv ntauwd yog ntim nrog cov khoom ntim tshwj xeeb, uas yog sab hauv impregnated nrog ntau - media catalyst. Tsav los ntawm tus kiv cua induced, cov pa roj malodorous dhau los ntawm txheej ntim. Nws los rau hauv tag nrho kev sib cuag - ntawm qhov chaw ntawm cov khoom ntim khoom - nrog rau cov kua -theem composite oxidant, uas yog sprayed nyob rau hauv ib tug nplua pos huab ntawm tshwj xeeb nozzles. Raws li kev ua haujlwm catalytic ntawm ntau- xov xwm catalyst, cov pa phem hauv cov pa roj malodorous tau decomposed kom huv si.
Scope of Application: Kev siv dav dav; tshwj xeeb tshaj yog tsim nyog rau kev kho mob loj - ntim, nruab nrab- mus rau - cov pa paug paug siab, thiab ua kom pom kev tshem tawm zoo heev rau cov pa phem hydrophobic.
Qhov zoo: me me hneev taw, peev peev tsawg, thiab cov nqi khiav lag luam tsawg; yooj yim los tswj thiab npaj rau kev siv tam sim.
Disadvantages: Thaum resistant rau poob siab loads thiab loj heev tsis cuam tshuam los ntawm kev hloov nyob rau hauv cov pa phem concentration los yog kub, tus txheej txheem yuav tsum tau noj ib co ntawm cov tshuaj reagents.
Tsawg-Cub Plasma
Tsawg-plasma qhov kub thiab txias sawv cev rau plaub lub xeev ntawm cov teeb meem, tom qab lub xeev cov khoom, kua, thiab gaseous. Thaum cov hluav taws xob siv hluav taws xob mus txog qhov hluav taws xob hluav taws xob ntawm cov roj, cov roj molecules tau tawg los ntawm dielectric, tsim cov khoom sib xyaw uas muaj xws li electrons, ntau yam ions, atoms, thiab dawb radicals. Thaum lub sij hawm tso tawm cov txheej txheem no, txawm hais tias qhov kub ntawm electron yog qhov siab heev, qhov kub ntawm cov khoom hnyav tseem qis heev; yog li ntawd, tag nrho cov kab ke tswj hwm qhov qis -kub lub xeev-li no lub npe "low-kub plasma." Kev degradation ntawm cov pa phem los ntawm qhov qis -plasma kub yog nyob ntawm kev cuam tshuam ntawm cov high- hluav taws xob electrons, dawb radicals, thiab lwm yam khoom siv nrog cov pa phem uas muaj nyob hauv cov pa khib nyiab. Qhov kev cuam tshuam no ua rau cov pa phem molecules decompose nyob rau lub sijhawm luv luv, ua rau muaj kev cuam tshuam tom qab uas thaum kawg ua tiav lub hom phiaj ntawm cov pa phem degradation.
Tsawg-cov cuab yeej siv cua kub plasma purification muaj txiaj ntsig zoo hauv kev kho ntau yam kev ua qias tuaj, suav nrog VOCs, malodorous gases, odors, roj fumes, thiab plua plav; Nws kuj tseem siv tau rau kev tua kab mob thiab ua kom tsis muaj menyuam. Tsawg-plasma qhov kub thiab txias yog qhov kev ua kom huv huv tshiab uas yuav tsum tsis muaj tshuaj ntxiv, tsis muaj dej khib nyiab lossis cov khoom pov tseg, thiab tsis ua rau muaj kuab paug thib ob.
