Industrial oxygen ntau lawmcov khoom siv, raws li lub npe implies, yog cov cuab yeej siv hauv kev tsim khoom los tsim cov pa oxygen.
Yog li dab tsi yog txoj kev ntawm kev lag luam oxygen ntau lawm?
Feem ntau peb feem ntau siv cov txheej txheem ua cov pa oxygen los ntawm decomposing hydrogen peroxide los yog poov tshuaj permanganate hauv chav kuaj, uas muaj cov yam ntxwv ntawm cov tshuaj tiv thaiv sai, kev ua haujlwm yooj yim thiab yooj yim sau cov khoom siv oxygen ua tshuab, tab sis tus nqi siab thiab tsis tuaj yeem ua rau loj. kom muaj nuj nqis, yog li nws tsuas yog siv tau hauv chav kuaj.Kev tsim khoom lag luam yuav tsum xav txog seb cov khoom siv raw cov pa oxygen generator hom twg yog qhov yooj yim kom tau txais, txawm tias tus nqi pheej yig, txawm tias tus nqi qis, txawm tias nws tuaj yeem tsim tau ntau thiab muaj kev cuam tshuam rau ib puag ncig.
Cov hauv qab no piav qhia txog cov txheej txheem tshwj xeeb ntawmindustrial oxygen ntau lawm.
1. Txoj kev sib cais cua txias
Cov khoom tseem ceeb ntawm huab cua yog oxygen thiab nitrogen.Kev siv cov pa oxygen thiab nitrogen boiling point yog txawv, kev npaj cov pa oxygen los ntawm huab cua yog hu ua cua sib cais txoj kev.Ua ntej ntawm tag nrho cov, huab cua ua ntej txias, purification (kom tshem tawm ib tug me me ntawm noo noo, carbon dioxide, acetylene, hydrocarbons thiab lwm yam gases thiab plua plav thiab lwm yam impurities nyob rau hauv cov huab cua), thiab ces compressed, txias, kom lub sab saum toj kaum. hom ntawm cov tshuab hluav taws xob oxygen rau hauv cov pa ua kua.
Tom qab ntawd, siv qhov sib txawv ntawm cov ntsiab lus kub ntawm cov pa oxygen thiab nitrogen, cov cua ua kua yog evaporated thiab condensed ob peb zaug nyob rau hauv lub distillation ntauwd kom cais cov pa thiab nitrogen.Yog tias koj ntxiv qee cov khoom siv ntxiv, koj tuaj yeem rho tawm argon, neon, helium, krypton, xenon thiab lwm yam tsis tshua muaj inert gases uas muaj tsawg heev hauv huab cua.Cov pa oxygen uas tsim los ntawm cov cuab yeej sib cais huab cua yog compressed los ntawm compressor, thiab thaum kawg cov pa compressed yog loaded rau hauv siab cylinders rau cia, los yog ncaj qha thauj mus rau factories thiab workshops los ntawm pipelines.
2. Molecular sieve oxygen ntau lawm txoj kev (adsorption method)
Siv cov yam ntxwv ntawm nitrogen molecules loj dua oxygen molecules, cov pa oxygen nyob rau hauv cov huab cua yog cais tawm siv ib tug tshwj xeeb tsim molecular sieve.Ua ntej, lub compressor quab yuam cov huab cua qhuav los ntawm molecular sieve rau hauv lub tshuab nqus tsev adsorber, nitrogen molecules nyob rau hauv cov huab cua yog adsorbed los ntawm molecular sieve, oxygen rau hauv lub adsorber, thaum cov pa oxygen nyob rau hauv lub adsorber nce mus txog ib tug npaum li cas (siab mus txog ib tug tej yam. qib), koj tuaj yeem qhib lub valve kom tso cov pa oxygen.
Tom qab ib lub sijhawm, nitrogen adsorbed los ntawm molecular sieve maj mam nce, lub peev xwm adsorption tsis muaj zog, thiab purity ntawm cov zis oxygen txo, yog li cov nitrogen adsorbed ntawm molecular sieve yuav tsum tau muab tso tawm los ntawm lub tshuab nqus tsev twj tso kua mis, thiab tom qab ntawd rov ua dua. cov txheej txheem saum toj no.Hom kev tsim cov pa oxygen no tseem hu ua adsorption method.
