Tsis tu ncuaMethanol concentration ntsuasNws yog ib qho tseem ceeb hauv kev tsim cov tshuaj methanol roj cell (DMFC), tshwj xeeb tshaj yog nyob rau hauv kev txhim kho lub zog tsim efficiency thiab roj teeb lub neej ntev. Lub zog tsim hluav taws xob tau txiav txim siab los ntawm oxidation cov tshuaj tiv thaiv ntawm methanol ntawm cov electrode nto, thiab oxidation cov tshuaj tiv thaiv yog cuam tshuam los ntawm cov tshuaj methanol concentration.
Qhov tseeb batching ntawm cov tshuaj methanol yog qhov yuav tsum tau ua ua ntej ntawm cov tshuaj tiv thaiv electrochemical thiab smoother electron hloov. Tsis tas li ntawd, nws lav qhov siab dua qhov tso zis hluav taws xob thiab qhov ceev tam sim no, thaum kawg txhim kho kev ua haujlwm ntawm lub zog hloov pauv. Cov zis hluav taws xob ruaj khov yog lwm qhov laj thawj rau kev tswj hwm ntawm methanol concentration. Kev sib txawv ntawm lub zog tso zis yog qhov tshwm sim ntawm kev hloov pauv hauv methanol concentration. LonnmeterMethanol concentration meteryog ib qhov zoo tshaj plaws gauges kom paub methanol concentration nyob rau hauv lub sij hawm, tshwj xeeb tshaj yog tseem ceeb nyob rau hauv automation ntau lawm kab.
Kev Ntsuas Method ntawm Methanol Concentration
No.1 Kev Ntsuas Qhov Ntsuas
Adensity meter rau cov kuasiv kev sib raug zoo ntawm qhov ceev thiab concentration ntawm cov tshuaj methanol kom paub qhov kev soj ntsuam tas li ntawm methanol concentration. Cov txiaj ntsig ntawm txoj kev no yog nyob rau hauv kev ntsuas tus txheeb ze ruaj khov thiab qhov tseeb siab raws li tus qauv preset density-concentration-temperature kev sib raug zoo qauv. Hu rau peb cov engineers kom paub ntau ntxiv txog qhovroj teeb density meterhauv kab.
No.2 Txoj Kev Refractive
Qhov concentration ntawm cov tshuaj methanol tuaj yeem raug xam los ntawm ib qho inlinedensitometerlos yogrefractometerRaws li qhov sib txawv ntawm qhov ntsuas refractive ntawm methanol thiab nws cov kuab tshuaj. Txawm hais tias nws yooj yim rau kev khiav lag luam thiab muab cov lus teb sai, qhov ntsuas qhov ntsuas tsis sib txawv ntawm qhov sib txawv. Yog li ntawd, kev kho qhov kub thiab txias yog qhov tsim nyog rau kev ntsuas kom raug.
No.3 Near-Infrared Spectroscopy (NIR)
Ib qho ze-infrared spectrometer ua haujlwm ntawm tus qauv kev sib raug zoo ntawm qhov nqus thiab methanol concentration, ua lub sijhawm kuaj xyuas cov tshuaj methanol thiab ntsuas qhov nqus ntawm cov wavelengths tshwj xeeb. Feem ntau, methanol qhia txog qhov nqus siab tshaj plaws hauv thaj tsam ze-infrared spectral.
No.4 Electrochemical Sensor
Ib qho electrochemical sensor pom methanol concentration los ntawm kev hloov pauv tam sim no lossis muaj peev xwm oxidation-txo ntawm qhov chaw. Nws ua rau lub sijhawm saib xyuas online ntawm tus nqi qis rau cov lus teb sai, siab rhiab heev thiab kev xaiv zoo. Txawm li cas los xij, kev ruaj ntseg thiab kev ua neej nyob muaj kev cuam tshuam rau kev sib kis thiab kev hloov ib puag ncig. Nws ua hauj lwm nyob rau hauv ib txwm tsuas yog tsis tu ncua calibration thiab hloov.
No.5 Roj Cell
Methanol concentration tuaj yeem raug xam los ntawm qhov tam sim no thiab qhov hluav taws xob tsim los ntawm cov roj hluav taws xob tshwj xeeb, uas cov tshuaj tiv thaiv oxidation tshwm sim los saib xyuas methanol concentration thiab siv cov peev txheej.
Hu rau peb cov engineers kom tau txais kev ntsuas kev ntsuas ntawm methanol concentration. Thov cov lus hais dawb tam sim no!
