Catalytic combustion technology ua ib qho ntawm VOCs pov tseg cov txheej txheem kho roj, vim tias nws qhov kev ua kom huv huv siab, qhov kub thiab txias qis (<350 ° C), combustion yam tsis muaj nplaim taws, yuav tsis muaj cov pa phem thib ob xws li NOx tiam, kev nyab xeeb, txuag hluav taws xob thiab kev tiv thaiv ib puag ncig thiab lwm yam ntxwv, hauv kev lag luam kev tiv thaiv ib puag ncig muaj kev cia siab zoo.Raws li qhov tseem ceeb ntawm kev sib txuas ntawm catalytic combustion system, catalyst synthesis technology thiab kev siv cov cai tseem ceeb tshwj xeeb.
1. Lub hauv paus ntsiab lus ntawm cov tshuaj tiv thaiv catalytic combustion
Lub hauv paus ntsiab lus ntawm catalytic combustion cov tshuaj tiv thaiv yog hais tias cov organic pov tseg gas yog kiag li oxidized thiab decomposed nyob rau hauv qhov kev txiav txim ntawm lub catalyst ntawm ib tug qis kub kom ua tiav lub hom phiaj ntawm purifying cov roj.Catalytic combustion yog ib qho roj-kheej theem catalytic cov tshuaj tiv thaiv, thiab nws lub hauv paus ntsiab lus yog hais tias reactive oxygen hom koom nyob rau hauv sib sib zog nqus oxidation.
Hauv cov txheej txheem catalytic combustion, kev ua haujlwm ntawm cov catalyst yog txo qis lub zog ua kom muaj zog ntawm cov tshuaj tiv thaiv, thaum cov reactant molecules yog enriched ntawm lub catalyst nto kom nce cov tshuaj tiv thaiv.Nrog kev pab los ntawm ib tug catalyst, cov organic khib nyiab roj yuav hlawv flameless ntawm ib tug qis ignition kub thiab tso ib tug loj npaum li cas ntawm tshav kub thaum oxidizing thiab decomposing rau CO2 thiab H2O.
3. Lub luag haujlwm thiab kev cuam tshuam ntawm VOCs catalyst hauv catalytic combustion system
Feem ntau, tus kheej-combustion kub ntawm VOCs yog siab, thiab ua kom lub zog ntawm VOCs combustion tuaj yeem txo los ntawm kev ua kom cov catalyst, thiaj li txo qhov kub ntawm qhov hluav taws kub, txo lub zog noj thiab txuag nqi.
Tsis tas li ntawd, qhov kub combustion ntawm cov dav dav (tsis muaj catalyst) yuav siab tshaj 600 ° C, thiab cov combustion no yuav tsim nitrogen oxides, uas feem ntau hais tias yog NOx, uas kuj yog ib qho kuab paug los tswj nruj heev.Catalytic combustion yog combustion yam tsis muaj qhov qhib nplaim taws, feem ntau hauv qab 350 ° C, yuav tsis muaj NOx tiam, yog li nws muaj kev nyab xeeb dua thiab zoo ib puag ncig.
4. Dab tsi yog airspeed?Dab tsi yog yam uas cuam tshuam rau airspeed
Nyob rau hauv VOCs catalytic combustion system, cov tshuaj tiv thaiv qhov chaw ceev feem ntau yog hais txog qhov ntim qhov chaw ceev (GHSV), xav txog kev ua cov peev txheej ntawm cov catalyst: cov tshuaj tiv thaiv qhov chaw ceev yog hais txog cov roj ua tiav ib chav tsev ib lub sijhawm ib chav tsev ntawm cov catalyst. nyob rau hauv cov xwm txheej tshwj xeeb, chav tsev yog m³ / (m³ catalyst •h), uas tuaj yeem ua kom yooj yim li h-1.Piv txwv li, cov khoom raug cim nrog qhov chaw ceev 30000h-1: nws txhais tau tias txhua lub cubic catalyst tuaj yeem tuav 30000m³ tso pa roj ib teev.Cov huab cua ceev qhia txog VOCs ua lub peev xwm ntawm cov catalyst, yog li nws muaj feem cuam tshuam nrog kev ua haujlwm ntawm catalyst.
5. Kev sib raug zoo ntawm cov khoom muaj nqi hlau thauj khoom thiab airspeed, qhov siab dua cov ntsiab lus hlau zoo dua?
Qhov kev ua tau zoo ntawm cov khoom siv hlau muaj txiaj ntsig muaj feem xyuam nrog cov ntsiab lus ntawm cov hlau muaj txiaj ntsig, qhov loj me thiab tawg.Qhov zoo tshaj plaws, cov hlau muaj txiaj ntsig zoo heev, thiab cov hlau muaj txiaj ntsig yog tam sim no ntawm cov cab kuj hauv cov khoom me me (ntau nanometers) nyob rau lub sijhawm no, thiab cov hlau tseem ceeb yog siv rau qhov loj tshaj plaws, thiab kev ua haujlwm ntawm cov catalyst yog qhov zoo. correlated nrog cov ntsiab lus muaj nuj nqis hlau.Txawm li cas los xij, thaum cov ntsiab lus ntawm cov hlau muaj txiaj ntsig zoo siab rau qee qhov, cov khoom siv hlau yooj yim sib sau ua ke thiab loj hlob mus rau hauv cov khoom loj, qhov sib cuag ntawm cov hlau muaj txiaj ntsig thiab VOCs txo qis, thiab feem ntau ntawm cov hlau muaj txiaj ntsig yog qhwv rau sab hauv, nyob rau lub sijhawm no, nce cov ntsiab lus ntawm cov khoom muaj txiaj ntsig zoo tsis yog qhov tsim nyog rau kev txhim kho cov kev ua haujlwm catalyst.
