Nitrogen-ua cov cuab yeej yog tau los ntawm kev sib cais huab cua thiab nitrogen los ntawm cov khoom siv raw siv cua ua raw khoom.
Muaj peb hom kev lag luam nitrogen:
◆ Cryogenic cua cais nitrogen
Cryogenic cua sib cais nitrogen yog ib txwm muaj nitrogen ntau lawm txoj kev uas tau nyob rau hauv lub xyoo caum tsis ntev los no.Nws siv huab cua los ua cov khoom siv raw, yog compressed, purified, thiab tom qab ntawd siv cov cua kub pauv los ua kua dej ua kua.Cov cua ua kua feem ntau yog sib xyaw ua kua oxygen thiab kua nitrogen, uas muaj cov ntsiab lus sib txawv ntawm cov pa oxygen thiab kua nitrogen (qhov kub ntawm qhov qub yog -183 ° C ntawm 1 atm, thiab tom kawg yog -196 ° C) , thiab cov distillation los ntawm cov kua cua cais lawv kom tau nitrogen.Cov khoom siv cryogenic cua sib cais nitrogen yog qhov nyuaj, npog thaj tsam loj, muaj tus nqi siab, thiab muaj peev txheej loj hauv cov cuab yeej siv, cov nqi khiav lag luam siab, tsis tshua muaj roj (12 mus rau 24 teev), kev txhim kho siab thiab lub voj voog ntev.Cov khoom siv dav dav, kev teeb tsa thiab kev tsim kho vaj tse, cov khoom siv qis dua 3500Nm3 / h, kev nqis peev loj ntawm PSA cov cuab yeej ntawm tib cov kev qhia tshwj xeeb yog 20% ​​~ 50% qis dua qhov cua sib cais chav tsev cryogenic.Lub cryogenic cua sib cais nitrogen cog yog tsim rau loj-scale industrial nitrogen ntau lawm, thaum nruab nrab thiab me me scale nitrogen ntau lawm yog uneconomical.

◆ Molecular sieve nitrogen
Ib txoj hauv kev uas huab cua yog siv los ua raw khoom, carbon molecular sieve yog siv los ua ib qho adsorbent, lub siab viav vias adsorption txoj cai yog siv, thiab xaiv adsorption ntawm oxygen thiab nitrogen los ntawm carbon molecular sieve yog siv los cais nitrogen thiab oxygen. feem ntau hu ua PSA nitrogen ntau lawm.Txoj kev no yog ib lub tshuab tsim cov nitrogen tshiab uas tau tsim sai heev hauv xyoo 1970s.Piv nrog rau cov txheej txheem nitrogen ntau lawm, nws muaj cov txheej txheem yooj yim, qib siab ntawm automation, ceev roj ntau lawm (15 mus rau 30 feeb), kev siv hluav taws xob tsawg, cov khoom siv purity tuaj yeem hloov kho raws li cov neeg siv khoom xav tau hauv ntau yam, kev ua haujlwm yooj yim thiab kev saib xyuas. , kev lag luam Tus nqi qis thiab muaj zog adaptability ntawm cov cuab yeej, yog li nws muaj kev sib tw hauv cov khoom siv nitrogen hauv qab 1000Nm3 / h.Nws yog ntau thiab nrov ntawm cov neeg siv me me thiab nruab nrab nitrogen.PSA nitrogen tau dhau los ua thawj qhov kev xaiv rau cov neeg siv nruab nrab thiab me me nitrogen.txoj kev.

◆ Membrane cua cais nitrogen
Huab cua yog siv los ua cov khoom siv raw, thiab nyob rau hauv cov xwm txheej sib txawv, cov pa roj ntawm cov khoom sib txawv xws li oxygen thiab nitrogen muaj qhov sib txawv permeation hauv daim nyias nyias kom cais cov pa thiab nitrogen.Piv nrog rau lwm cov khoom siv nitrogen-ua, nws muaj qhov zoo ntawm cov qauv yooj yim, ntim me me, tsis muaj qhov hloov pauv, tsis tu ncua, roj ntau lawm (≤3 feeb), yooj yim muaj peev xwm nce, thiab lwm yam. Nws yog tshwj xeeb tshaj yog haum rau nitrogen purity ≤ 98. % ntawm cov neeg siv nruab nrab thiab me me nitrogen muaj tus nqi zoo tshaj plaws / kev ua tau zoo.Thaum lub purity ntawm nitrogen yog siab tshaj 98%, nws yog ntau tshaj 15% siab tshaj PSA nitrogen-ua cov cuab yeej ntawm tib specification.
