M'gawo lopanga ma cell a haidrojeni, Membrane Electrode Assembly (MEA) imagwira ntchito ngati gawo lofunikira pakusinthira mphamvu, ndikudziwitsa mwachindunji momwe batire imagwirira ntchito komanso moyo wake wonse. Gawo loyamba la kupanga MEA kudzera pakutengera kutentha ndikusakaniza kochititsa chidwi - sitepe yofunika kwambiri yomwe imakhudza mtundu wazinthu zomaliza. Izi zimafuna kusakaniza bwino kwa Pt-C catalysts, solvents, ndi binders kupanga uniformly omwazikana khola osakaniza.
Traditional kusanganikirana kulimbana ndendende kulamulira chiwerengero cha chigawo chilichonse ndi kubalalitsidwa boma, zikubweretsa nkhani monga ❖ kuyanika osagwirizana ndi kuchepetsa chothandizira ntchito wotsatira. Kugwiritsa ntchito kwainline density mita imapereka yankho lopambana, kupangitsa kuwongolera bwino kwa magawo a zigawo ndi zotsatira za kubalalitsidwa kudzera pakuwunika zenizeni za kusintha kwa kachulukidwe ka slurry.
Kampani ya Lonnmeter Group, yomwe ikutsogolera komanso kugulitsa ma inline density meters, yadzipereka kwa zaka zambiri popereka mayankho aukadaulo kwa makasitomala padziko lonse lapansi. Mayankho awa athandiza mafakitale ambiri, mafakitale opanga magetsi, ndi mabizinesi opangira zitsulo kuchepetsa ndalama komanso kukonza bwino.
Udindo Wofunika Kwambiri Wosakaniza Slurry
Kagwiridwe kake ka ma hydrogen fuel cell MEAs kumadalira kwambiri kufanana ndi kukhazikika kwa ma catalyst slurries. Mwachitsanzo, anode slurries amafuna 15% Pt-C chothandizira uniformly omwazika mu osakaniza zosungunulira 40% deionized madzi, 40% methanol, ndi 5% ionomer njira; ma cathode slurries amafuna kuchuluka kwa chothandizira (20%) ndi binder (10%). Chiŵerengero cholondolachi sichimangokhudza maonekedwe a slurry komanso amakhudza mwachindunji kugawidwa kwa malo othandizira komanso ma proton conductivity.
Kuwongolera kachulukidwe kosayenera kungayambitse kuphatikizika kapena kusungunuka, zomwe zimapangitsa kuti pakhale makulidwe osagwirizana a chothandizira komanso ngakhale magwiridwe antchito onse a batri. Mwachitsanzo, kachulukidwe kachulukidwe kameneka kangasonyeze kutulutsa mpweya wosungunulira mopitirira muyeso, kukulitsa kukhuthala kwa slurry ndikupangitsa kuwonongeka kwa "peel lalanje" kapena "pinhole" pakupaka; kachulukidwe m'munsi angasonyeze chothandizira osakwanira, kulephera kupereka mokwanira anachita malo ndi kuchepetsa mphamvu batire.
Zoletsa Zachikhalidwe Zakuchuluka kwa Slurry Density Control
Kusanganikirana kwa slurry kwachikale kumadalira kuyeza kwake pamanja ndi kuyezetsa popanda intaneti m'mapulaimale. Njirayi imatsalira kumbuyo kwa nthawi yeniyeni - kupeza zotsatira zoyeserera kuchokera ku sampuli nthawi zambiri kumatenga mphindi 15-30, panthawi yomwe slurry imatha kulowa munjira ina, zomwe zimapangitsa kuti ziwonongeke zambiri.
Ntchito pamanja amavutika kudziwa nanoscale chothandizira tinthu agglomeration. Kuonjezera apo, zinthu monga kusintha kwa kutentha ndi kutuluka kwa zosungunulira kumayambitsa kusinthasintha kwamphamvu kwa slurries, zomwe chikhalidwe cha chikhalidwe sichingathe kulipira panthawi yeniyeni, ndikuwonjezera kuopsa kwa kusakhazikika kwa khalidwe.
Mfundo Yogwirira Ntchito ndi Ubwino Waukadaulo
Kuti athane ndi mavutowa, mainjiniya a Lonnmeter adapanga ma inline density metres kutengera mfundo ya mphamvu ya Coriolis, yomwe imayesa kugwedezeka kwamadzimadzi kuti apeze zambiri zanthawi yeniyeni molunjika mpaka ±0.001 g/cm³. Mu kusakaniza slurry wa hydrogen mafuta selo, izi mkulu-mwatsatanetsatane kuwunika zipangizo akhoza kuikidwa pa kotuluka akasinja kusakaniza kapena kufalitsidwa mapaipi mosalekeza kusonkhanitsa kachulukidwe ndi kutentha deta, ndi ma aligorivimu chipukuta misozi kuchotsa zotsatira za kutentha pa kachulukidwe.
Kupitilira Coriolis density metres, Lonnmeter yapanganso ma inline density metres monga kukonza ma foloko kachulukidwe mita ndi akupanga kachulukidwe mita kuti apereke anzeru kachulukidwe kuwunika masensa pamikhalidwe yosiyanasiyana yogwirira ntchito. Pamene kuona kuti cathode slurry kachulukidwe kuposa chandamale mtengo, dongosolo basi kuwerengetsera kupatuka ndipo anawonjezera mlingo woyenera wa zosungunulira mwa metering mpope; ngati kachulukidwe kake kakuchepa kwambiri, mowa womwazira womwaza womwazikana umawonjezeredwa. Kuwongolera kosinthika kumeneku sikumangokonza zophatikizika komanso kulosera zomwe zingachitike posanthula mbiri yakale. Kachulukidwe kachulukidwe kachulukidwe kakachulukidwe kachulukidwe kake, makinawa amayambitsa ma alarm kuti ayambitse kubalalitsidwa kosafanana kapena kupatukana kwa gawo, kupewa ngozi zamtundu wa batch kupitilira.
Zotsatira za Continuous Density Monitoring
Kukhazikika Kwama cell amafuta
Lonnmeter inline density meters athandiza opanga ma cell amafuta kuti apindule kwambiri pakusanganikirana kwa slurry. Kupyolera mu kuyang'anira nthawi yeniyeni ndi kulamulira mwanzeru, kusinthasintha kwa slurry density ranges kuchepetsedwa kwambiri kuchoka pa ± 0.03 g/cm³ kufika ± 0.001 g/cm³. Kusintha kumeneku kumathandizira mwachindunji kusasinthika kwazinthu komanso kukhazikika kwa magwiridwe antchito, ndikuwonjezera kuchuluka kwamafuta amafuta abizinesi imodzi ndi 15%.
Kuchita Bwino Kwambiri Kupanga Bwino
Nthawi yopangira batch imodzi yafupikitsidwa, ndikusungidwa kwapachaka kupitilira $300,000 pamitengo ya zinthu ndi kukonzanso. Kuphatikiza apo, kugwiritsa ntchito ma inline density metres kwakwaniritsa zonse. Mophatikizika ndi machitidwe a DCS, amalola kuwongolera kwa digito kuyambira pakuwongolera formula mpaka kutsatiridwa bwino, kuyika maziko opangira ma cell amafuta a haidrojeni.
Kufunika Kwambiri Pamakampani a Hydrogen Energy
Monga chonyamulira chachikulu cha mphamvu zoyera, ma cell amafuta a hydrogen amakumana ndi zovuta ziwiri zowongolera magwiridwe antchito ndikuchepetsa mtengo. Kugwiritsa ntchito ukadaulo wa inline density meter sikungothetsa zovuta zazikulu zakupanga kwa MEA komanso kumathandizira kukweza kwaukadaulo pamakampani onse amagetsi a hydrogen.
Ngati mukufunama inline process sensorskuti muchepetse ndalama ndikuwonjezera kuchita bwino pakupanga makina, zida zanzeru za Lonnmeter ndi chimodzi mwazosankha zanu zabwino. Kampaniyo ikuperekaZitsanzo zaulere za 100 padziko lonse lapansi-zambiri ndizochepa, choncho chitanipo kanthu mwachangu! Lumikizanani nafe kuti mupeze yankho laulere lokhazikika ndikufunsira zitsanzo zaulere.
