Nyob rau hauv daim teb ntawm kev muaj roj av ntau lawm, kua nitrogen tau dhau los ua qhov tsis tseem ceeb thiab tseem ceeb rau nws qhov tsis tshua muaj qis - kub yam ntxwv. Raws li cov txuj ci ua kua nitrogen ntau lawm, sib sib zog nqus cov kev ua kom zoo nkauj thiab kev ua kom tiav, nws yuav luag tsis yooj yim sua, nws yuav tsum ua tiav cov kev ua kom tiav los ntawm cryogenic.
Yam tseem ceeb
Ua kua nitrogen purity produced los ntawm cryogenic, sib cais raws qhov sib txawv tseem ceeb hauv cov ntsiab lus npau npau ntawm txhua qhov sib txawv hauv huab cua. Cov huab cua yog thawj zaug compressed thiab tsa lub siab, tom qab ntawd qhia rau hauv cov cuab yeej txias kom txias, thiab tom qab ntawd nkag mus rau cov khoom tseem ceeb ntawm cov pej thuam distillation ntauwd. Nyob rau hauv lub distillation ntauwd, lub boiling taw tes ntawm nitrogen yog hais txog - 196 degree, uas yog tsawg. Nws yog thawj zaug rau liquefy thiab cais los ntawm cov roj sib xyaw thaum lub sijhawm kawm maj mam. Los ntawm kev ua tib zoo tsim cov qauv sab hauv ntawm cov phiaj xwm pej thuam xws li kub thiab lwm yam, thiab lwm yam ntawm cov kua nitrogen muaj peev xwm txhim kho. Hauv cov khoom siv txias ua kom sib cais nqus cov khoom sib cais, tom qab ntau cov txheej txheem ua kua rau ntau dua 99.999%, uas yog 5n qib qib siab uas tau hais txog hauv kev lag luam.
Cov ntaub ntawv ntsig txog cov ntaub ntawv
Nyob rau hauv ib tug loj tshaj lij choj lag luam enterprise, thaum nws cov cuab yeej sib cais ntawm cov khoom siv ua kua kom zoo rau kev lag luam ua kua rau ntawm kev lag luam ua kua rau ntawm kev lag luam Piv txwv li, hluav taws xob chip tsim, siab-}}}}}}}}}}}}}}}} Lub sijhawm tsim khoom, uas tuaj yeem ua kom muaj cov nti khov kho.
Txawm li cas los xij, txawm tias kev thev naus laus zis tam sim no tuaj yeem ua tiav cov kev huv siab, nws tseem tab tom ncav cuag 100% kev coj dawb huv. Hauv kev tsim khoom tiag tiag, ntau yam txwv txoj kev txhim kho ntxiv ntawm cov kua nitrogen purity.
Qhov nyuaj ntawm raw cov ntaub ntawv
Ua ntej tshaj plaws, cov khoom siv khoom siv raw yog tsis yog ntshiab thiab muaj cov khoom xyaw ua ke. Ntxiv nrog rau lub ntsiab nitrogen thiab oxygen, nws kuj tseem muaj argon, carbon dioxide, dej vapred gases. Although before the air enters the cryogenic system, it will pass through a strict pretreatment process such as intercepting solid particles impurities by efficient filters, reducing water vapor content in the drying equipment, and strive to remove most impurities, no matter how advanced and perfect the pretreatment process is, extremely trace impurities are still inevitably retained. Piv txwv li, cov dej vapor cov ntsiab lus hauv huab cua tuaj yeem poob rau lub dew taw tes kub hauv qab -65℃tom qab pretreatment. Txawm li ntawd los, hauv cov dej muaj zog heev, ib qho me me ntawm cov dej vapor tseem tuaj yeem ua rau muaj kev cuam tshuam, uas muaj qhov tsis muaj txiaj ntsig ntawm kev ua kua ntawm cov kua nitrogen. Nyob rau hauv cov zaub mov khov kev lag luam, yog tias dej vapor implities nyob rau hauv cov khoom noj muaj kua, nws kuj yuav ua rau cov zaub mov nab kuab, nws tuaj yeem ua rau cov khoom noj kom khov, cuam tshuam thiab zoo ntawm cov zaub mov.
Thib ob, kev ua tau zoo thiab xwm txheej ntawm lub ntaus ntawv nws tus kheej tsis zoo tag nrho. Cov phiaj xwm ntauwd lossis fillers nyob rau hauv lub pej thuam distillation yog raug rov qab ua haujlwm nrog cov pa roj av, thiab hnav kom zoo rau kev ua haujlwm ntau dhau los, thiab hnav kom zoo rau kev sib cais ntawm cov nyhuv sib cais ntawm cov pej thuam distillation ntauwd. Cov khoom lag luam sealing kev ua tau zoo kuj tseem ceeb heev rau kev coj dawb huv ntawm cov kua nitrogen. Yog tias kev sib khi tsis nruj, huab cua sab nraud yuav nkag mus rau hauv cov kab ke, qhia cov pa, plua plav, thiab lwm yam kom txo cov kev ua kua ntawm cov kua nitrogen. Cov kev txheeb cais uas cuam tshuam tau qhia tau tias thaum cov khoom siv khoom siv yog tas me ntsis, lub suab nrov ntawm cov kua dej tsis ntev los ntawm 99.995% nyob rau hauv ib lub sijhawm luv luv, uas muaj qhov cuam tshuam tseem ceeb ntawm kev tsim khoom zoo. Noj Kev Kho Mob Kev Lag Luam Ua piv txwv, qis} {{{{} Cov qauv tshuaj xyuas kev ua piv txwv, ua rau txo cov qauv kev ua ub no lossis kev puas tsuaj.
Xav txog ntawm lub tswv yim lub cev
Los ntawm lub hauv paus pom kev xav tau, raws li lub hauv paus ntsiab lus ntawm thermodynamics, muaj cov kev txwv uas muaj teeb meem hauv teeb meem sib cais. Txawm hais tias infinite multion - theem distillation yog siv tag nrho cov impurogen kom ua tiav txhua yam kev ua haujlwm los ntawm kev ua haujlwm tau ua kua ntau ntau cov teeb meem tsis txaus ntseeg. Raws li cov theem distillation nce, qhov nyuaj, nqi thiab kev siv zog ntawm cov khoom siv hluav taws xob ua rau nws tsis yooj yim rau kev sib cais ua kom tiav impurities.
Cov kua nitrogen ua los ntawm cryogenic tuaj yeem ua tiav cov kev ua kom siab kawg nrog cov thev naus laus zis thiab ua tau raws li kev xav tau nruj ntawm cov kev lag luam nruj heev. Txawm li cas los xij, vim muaj kev txwv ntau yam xws li cov khoom siv raw thiab thermodynamic cov kev txwv, nws yuav luag tsis yooj yim sua kom ncav cuag 100% purity. Txawm li cas los xij, nrog kev nce qib nruam ntawm thev naus laus zis, kev nthuav dav cov khoom lag luam ntawm cov khoom siv ua kua, txhim kho cov khoom lag luam zoo nkauj ntxiv, thiab txhawb nqa kev lag luam ntau rau qib siab dua.
