Oxygen suav txog li 20.9% ntawm cov huab cua thiab yog ib qho tseem ceeb ntawm lub ntiaj teb huab cua. Nws kuj yog ib yam khoom tseem ceeb tshaj plaws rau tag nrho lub neej hauv ntiaj teb. Hauv qhov xwm txheej, cov pa oxygen feem ntau yog tsim los ntawm photosynthesis ntawm cov nroj tsuag ntsuab thiab cyanobacteria. Photosynthesis yog txheej txheem loj tshaj plaws nyob rau hauv lub ntiaj teb los tsim cov organic teeb meem thiab tso tawm oxygen, muab cov organic teeb meem thiab oxygen rau yuav luag tag nrho cov dej num hauv lub neej. Nyob rau tib lub sijhawm, cov pa oxygen tso tawm los ntawm photosynthesis kuj yog thawj qhov chaw ntawm oxygen nyob rau hauv qhov chaw.
Lub siab electronegativity ntawm oxygen atoms ua rau oxygen heev oxidizing. Yog li ntawd, cov pa oxygen ntawm cov purities sib txawv yog dav siv hauv cov pa oxygen-enriched combustion, hlau smelting, hlau welding, pulp bleaching, dej mov thiab kua, kev kho mob cawm, aerospace thiab ntau lwm yam teb. Tshwj xeeb, nrog rau kev txhim kho kev lag luam hauv zej zog, tib neeg muaj kev xav tau ntau dua thiab siab dua rau cov ntsuas dej zoo thiab kev nyab xeeb ntawm cov dej hauv tsev thiab cov khoom tsim tawm, thiab cov kev xav tau rau cov dej nyob ib puag ncig zoo kuj nce ntxiv, uas tso cov kev xav tau ntau dua rau kev kho dej. txheej txheem thev naus laus zis hauv kev muab dej thiab tso dej. Nyob rau tib lub sijhawm, nrog kev txhim kho thiab kev vam meej ntawm kev lag luam, kev sib tw ntawm ntau yam khoom siv kho dej thiab cov thev naus laus zis tau dhau los ua nruj, thiab kev lag luam ntawm cov txheej txheem thev naus laus zis tau dhau los ua ib qho tseem ceeb tshaj plaws rau kev ntsuas kev nce qib thiab kev ua tau zoo. ntawm txheej txheem technology. Vim li no, kev siv cov pa oxygen siab purity yog ib feem tseem ceeb ntawm ntau yam kev kho dej tshiab thiab cov txheej txheem tau dhau los ua cov ntsiab lus kub hauv kev tshawb fawb ntawm cov dej thiab cov kua dej, xws li cov pa ntshiab oxygen aeration, ozone sterilization, advanced oxidation. , thiab lwm yam NEWEK, raws li cov kws tshaj lij cov khoom siv roj av, muab lub ntiaj teb nrog kev nyab xeeb, txhim khu kev qha, kev lag luam thiab ua tau zoo siab-purity oxygen generator tshuab rau kev siv.
PSA muaj oxygen generators 95% txog 99%
PSA (Pressure Swing Adsorption) cov tshuab hluav taws xob muaj cov pa oxygen tau siv dav hauv ntau lub lag luam los tsim cov pa oxygen nrog cov purity ntau ntawm 95% mus rau 99%. Cov tshuab hluav taws xob no ua haujlwm los ntawm kev sib cais cov pa oxygen los ntawm huab cua los ntawm cov txheej txheem cyclic uas muaj adsorption thiab desorption ntawm cov pa roj ntawm cov khoom siv molecular sieve.
Cov txheej txheem PSA feem ntau suav nrog cov kauj ruam hauv qab no:
Compression: Cov huab cua nyob ib puag ncig yog compressed mus rau qhov siab siab.
Adsorption: Cov cua compressed yog dhau los ntawm ib lossis ntau lub nkoj uas muaj cov khoom siv molecular sieve, xws li zeolites lossis carbon molecular sieves. Cov ntaub ntawv no tau xaiv adsorb nitrogen, tawm hauv qab cov dej muaj zog ntawm oxygen.
Desorption: Thaum lub txaj adsorbent tau saturated nrog nitrogen, lub siab raug txo, cia cov adsorbed nitrogen los desorb los ntawm molecular sieve.
Purging: Ib feem me me ntawm cov khoom siv oxygen yog siv los ntxuav cov desorbed nitrogen los ntawm lub txaj, npaj nws rau lub voj voog adsorption tom ntej.
Lub adsorption thiab desorption cycles yog ua nyob rau hauv ib tug cyclical yam, nrog ntau cov hlab ntsha ua hauj lwm nyob rau hauv ib tug staggered ib theem zuj zus kom ntseeg tau ib tug tas mus li mov ntawm oxygen.
PSA oxygen generators yog dav siv nyob rau hauv ntau yam kev siv, xws li:
Metalworking: Oxy-roj txiav, vuam, thiab lwm yam txheej txheem hlau fabrication.
Daim ntawv thov kev kho mob: Oxygen muab rau tsev kho mob, kho ua pa, thiab oxygen concentrators.
Kev siv tshuaj lom neeg: Cov tshuaj tiv thaiv oxidation, purging, thiab daim ntaub ntawv daim pam.
Kev kho dej khib nyiab: Aeration thiab oxidation txheej txheem.
Iav manufacturing: Oxy-roj combustion rau furnaces.
Cim npe nrov: Tuam Tshoj oxygen generator tshuab rau industrial siv, Tuam Tshoj oxygen generator tshuab rau industrial siv manufacturers, lwm tus neeg
