Organic khib nyiab kho cov cuab yeej yog ib qho cuab yeej tseem ceeb uas siv los ntxuav cov roj khib nyiab uas muaj cov pa phem uas tsim tawm thaum lub sij hawm tsim khoom lag luam. Nws tuaj nyob rau hauv ntau hom nrog ntau yam txuj ci, ua tau raws li kev kho mob xav tau ntawm kev lag luam sib txawv thiab rau cov roj khib nyiab nrog ntau qhov sib txawv thiab cov khoom sib xyaw. Tam sim no, cov khoom siv hluav taws xob siv hluav taws xob kho hluav taws xob hauv kev lag luam feem ntau suav nrog cov hauv qab no:
1. Cov khoom siv pa roj carbon adsorption
Cov cuab yeej ua kom cov pa roj carbon activated siv cov qauv ntxeem tau ntawm cov pa roj carbon activated (cov cheeb tsam tshwj xeeb tuaj yeem ncav cuag 800-}1500 m² / g) kom tshem tawm cov tsis muaj zog organic tebchaw (VOCs) los ntawm cov pa khib nyiab los ntawm lub cev adsorption. Nws cov txiaj ntsig tseem ceeb yog nyob rau hauv nws cov kev ua haujlwm siab adsorption (tus nqi adsorption rau cov tsis yog -cov khoom siv xws li benzene series compounds thiab cawv tuaj yeem ncav cuag ntau dua 90%), thiab nws cov qauv yooj yim thiab cov nqi khiav lag luam. Cov ntawv thov ib txwm muaj xws li kev siv cov pa khib nyiab tsawg hauv cov khw muag xim thiab cov chaw luam ntawv. Txawm li cas los xij, nws yuav tsum raug sau tseg tias cov pa roj carbon activated yuav tsum tau hloov lossis rov tsim dua tshiab tsis tu ncua tom qab saturation; txwv tsis pub, yuav muaj kuab paug thib ob. Tam sim no, cov nqi lag luam sib txawv nyob ntawm qhov kev ntim khoom (piv txwv li, kwv yees li 30,000-80,000 RMB rau 5000 m³ / h unit) thiab cov khoom siv (honeycomb activated carbon nqi 20%-30% ntau dua li cov pa roj carbon activated granular).
2. Catalytic combustion Equipment (RCO/RTO) Catalytic combustion khoom siv cov catalysts (xws li cov hlau muaj txiaj ntsig zoo li Pt thiab Pd) kom txo qis lub zog ua kom muaj zog ntawm cov organic oxidation cov tshuaj tiv thaiv, tso cov roj pov tseg kom tag nrho decomposed rau hauv CO₂ thiab H₂O ntawm qhov kub ntawm 250 .}0} Regenerative catalytic combustion (RCO) ua ke cov cua sov rov qab nrog cov khoom siv cua sov, ua tiav cov thermal efficiency ntau dua 95%, haum rau kev kho nruab nrab - rau - siab concentration (1000-5000 mg / m³) cov pa khib nyiab. Regenerative thermal oxidation (RTO), ntawm qhov tod tes, ncaj qha oxidizes ntawm qhov kub thiab txias (760-850 degree), ua tiav kev kho mob ntau dua 99%, tab sis nrog kev siv zog ntau dua. Kev nqis peev thawj zaug rau cov khoom siv no yog qhov loj (100,000-500,000 RMB), tab sis cov nqi khiav lag luam mus sij hawm tsawg tsawg, thiab nws feem ntau siv hauv kev lag luam xws li tshuaj lom neeg thiab txheej.
3. Biofilter Equipment Biofilters siv cov txheej txheem metabolic ntawm cov kab mob kom degrade organic teeb meem. Cov ntsiab lus tseem ceeb yog cov txheej txheem ntim khoom (xws li sawdust, nthuav av nplaum, thiab lwm yam), thiab cov txheej txheem tshuaj tsuag tswj hwm qhov chaw loj hlob microbial. Nws cov txiaj ntsig suav nrog tsis muaj kev ua qias tuaj nruab nrab thiab cov nqi khiav lag luam qis (tsuas yog siv hluav taws xob thiab cov khoom noj khoom haus yog xav tau). Txawm li cas los xij, nws txoj kev kho mob tau zoo cuam tshuam los ntawm qhov kub thiab txias (zoo tshaj 15{10}}35 degree), pH tus nqi (6-8), thiab av noo (40% -60%). Nws yog qhov tsim nyog rau kev kho mob qis qis (<500mg/m³) and high-volume waste gas, such as odor control in sewage treatment plants. Equipment prices vary depending on the packing volume (e.g., approximately 150,000-250,000 RMB for a 100m³ packing tank) and the℃of automation.
4. Tsawg-Tsuas Plasma Khoom Tsawg-cov khoom siv plasma kub ua rau siab -zog electrons, ions, thiab dawb radicals los ntawm siab-voltage tawm, rhuav tshem cov qauv molecular ntawm cov organic teeb meem. Nws cov yam ntxwv muaj xws li cov tshuaj tiv thaiv ceev ceev (milliseconds) thiab siv dav (nws tuaj yeem kho cov tshuaj uas muaj leej faj, nitrogen, thiab lwm yam heteroatoms). Txawm li cas los xij, nws ib leeg -kev ua haujlwm dhau los ntawm kev kho mob yog qhov tsawg (kwv yees li 60%-80%), thiab nws feem ntau yog siv los ua kev kho mob lossis ua ke nrog lwm cov thev naus laus zis. Cov khoom siv tus nqi sib txawv nyob ntawm lub zog (xws li, chav tsev 10kW tus nqi kwv yees li 50,000-100,000 RMB) thiab cov khoom siv electrode (stainless steel yog 30% pheej yig dua li titanium alloy). Nws yog tsim rau kev lag luam xws li electronics thiab pharmaceuticals.
5. Photocatalytic Oxidation Equipment Photocatalytic oxidation cov cuab yeej siv ultraviolet lub teeb kom excite catalysts xws li TiO₂ los tsim hydroxyl radicals (·OH), oxidizing thiab decomposing organic teeb meem. Nws qhov zoo muaj xws li tsis muaj consumables thiab muaj peev xwm los kho qis -concentration khib nyiab roj (<200mg/m³). However, it is limited by light intensity, waste gas humidity (requires <80%), and residence time (recommended >0.5s), thiab feem ntau yog siv hauv chav kuaj, tsev kho mob, thiab lwm qhov chaw zoo sib xws. Cov khoom siv tus nqi sib txawv nyob ntawm seb muaj pes tsawg lub teeb (piv txwv li, 20-lub teeb chav tsev nqi kwv yees li 20,000-50,000 RMB) thiab cov txheej txheem txheej txheej catalyst.
