Dab tsi yog ob-wavelength infrared absorption technology rau roj ntes?
Ob-wavelength infrared absorption twj yog ua raws li lub hauv paus ntsiab lus uas hydrocarbon gases thiab vapors nqus infrared zog ntawm tej wavelengths nyob rau hauv infrared cheeb tsam ntawm lub electromagnetic spectrum. Lub thiaj li hu ua ob wavelengths, uas yog, siv wavelength, hydrocarbons nyob rau hauv no wavelength tsis nqus infrared zog; ntsuas wavelength, hydrocarbons nyob rau hauv lub wavelength no muaj zog nqus infrared zog. Yog tias muaj cov hydrocarbons hauv cheeb tsam ntsuas, lub zog infrared ntsuas ntawm lub ntsuas ntsuas yuav qis dua li ntawm qhov ntsuas ntsuas. Cov cuab yeej muab cov concentration ntawm hydrocarbon gases thiab vapors los ntawm kev ntsuas qhov sib txawv ntawm ob.
Nws yog raws li FTIR thev naus laus zis - kev tshuaj xyuas - kuaj tshuab thiab tsim nyog rau kev tiv thaiv kev ua haujlwm thiab kev saib xyuas chaw ua haujlwm. Piv nrog rau hom catalytic combustion, nws muaj lub sijhawm teb ceev heev; nws tsis muaj qhov tshwm sim lom ntawm hom catalytic combustion; qhov tseeb tsis cuam tshuam los ntawm qhov ceev ntawm hydrocarbon gas ntws; qhov ntsuas ntau npaum li qis li 0 txog 1,000 ppm thiab siab li 0 txog 100 feem pua v/v; thiab nws tuaj yeem siv rau hauv qhov chaw inert gas vim nws tsis xav tau cov pa oxygen hauv kev ntsuas.
Nws tuaj yeem siv rau hauv qhov chaw hnyav heev los ntawm kev siv cov khoom tsis txav uas tsis cuam tshuam los ntawm kev vibration thiab poob siab; siv cov plua plav npog, txaws shields thiab daim iav cua sov tshuab; ib tug tsis-depleting electronically circulating infrared teeb qhov chaw nrog lub neej ntawm tsawg kawg yog 4 xyoo; tsis muaj kev laus ntawm tag nrho cov khoom tshwj tsis yog lub teeb; lub taub hau ntsuas muaj cov cuab yeej ntawm kev lees paub qhov yuam kev los ntawm kev ntsuas tus kheej tsis tu ncua; calibration yuav ua tau txhua txhua 6 lub hlis; yog li ntawd txo qis cov nqi txij nkawm thiab txo tus nqi ntawm kev saib xyuas piv rau FTIR txheej txheem. Lub calibration tuaj yeem ua tau txhua txhua 6 lub hlis, yog li txo qis tus nqi kho thiab muaj peev xwm ntawm lub tswb cuav piv rau FTIR thev naus laus zis.
Vim qhov kev txwv ntawm lub wavelength infrared, nws tsuas yog tsim rau hydrocarbons nrog carbon-hydrogen bonds thiab tsis tuaj yeem ntes cov pa roj xws li CS2, H2, CO, NH3, thiab hydrocarbons xws li acetylene thiab benzene. Yog li ntawd nws yog tsim nyog rau hydrocarbons ntev chains tshaj catalytic combustion sensors. Txawm hais tias thawj zaug peev yog kim, tus nqi tag nrho yog qis dua catalytic combustion tshuab.
