Muaj nitrogen ntau lawmsiv huab cua ua cov khoom siv raw, cais cov pa oxygen thiab nitrogen los ntawm nws. Cov txheej txheem tseem ceeb suav nrog cov txheej txheem cryogenic, lub siab viav vias adsorption txoj kev, thiab txoj kev sib cais membrane.
1. Txoj kev Cryogenic
Loj -scale industrial nitrogen tiam feem ntau siv cov tsoostxoj kev cryogenic. Txoj kev no siv cov huab cua los ua cov khoom siv raw: nyob rau hauv ib chav tsev sib cais cua cryogenic, huab cua yog txias txias thiab liquefied, ces oxygen thiab nitrogen raug cais los ntawm rectification raws li lawv cov ntsiab lus kub sib txawv.
Raws li ib txwm siv tshuab cua sib cais, cov txheej txheem cryogenic tau ua haujlwm rau tib neeg rau ntau xyoo lawm thiab tseem yog qhov tseem ceeb ntawm cov khoom siv nitrogen hauv Suav teb. Nrog rau cov keeb kwm kev lag luam ntev, nws yog qhov zoo- nkag siab thiab muaj qhov zoo tsis tuaj yeem hloov pauv (xws li, cov roj muaj peev xwm loj, cov khoom siab nitrogen purity, ruaj khov ua haujlwm) - nws kuj muaj cov txiaj ntsig tshwj xeeb: thaum tsim cov nitrogen, nws yields lwm cov pa roj xws li oxygen thiab argon. Yog li, txoj kev cryogenic tseem tseem muaj qhov loj thiab nruab nrab - daim ntawv thov sib cais huab cua.
Txawm li cas los xij, nws muaj cov txheej txheem nyuaj, kev xav tau siab rau cov cuab yeej tsim khoom, kev teeb tsa, thiab kev ua haujlwm, siab ib qho - lub sijhawm peev thiab cov nqi tsim vaj tsev, cov hneev taw loj, thiab cov pa roj qeeb (12 ~ 24 teev). Txoj kev cryogenic yog kev lag luam rau loj- nplai muaj nitrogen tiam sis tsis yog rau cov ntawv me me thiab nruab nrab- nplai.
2. Siab viav vias adsorption
Siab Swing Adsorption (PSA)yog ib ceg tseem ceeb ntawm cov uas tsis yog -cryogenic gas sib cais technologies nyob rau hauv cov roj sib cais science. Nws tau tsim tawm txawv teb chaws sai heev thaum xyoo 1960s thiab thaum ntxov 1970s.Siab viav vias adsorption nitrogen tiamsiv huab cua ua cov khoom siv raw thiab carbon molecular sieve ua tus adsorbent; Nws cais cov pa thiab nitrogen los ntawm PSA txoj cai, leveraging cov kev xaiv adsorption ntawm oxygen thiab nitrogen los ntawm carbon molecular sieve.
Piv nrog cov tsoos cryogenic nitrogen tiam,siab viav vias adsorption nitrogen tiammuaj cov yam ntxwv sib txawv: adsorption tshwm sim hauv chav tsev kub (tsis muaj teeb meem cryogenic), cov txheej txheem ntws yooj yim, cov cuab yeej siv tau yooj yim, lub tsev yog compact (tuaj yeem ntsia tau rau hauv qhov chaw seem uas twb muaj lawm), pib / kaw tau yooj yim, pib nrawm (ntau ntau lawm hauv 15 ~ 30 feeb), kev siv hluav taws xob tsawg, kev siv nyiaj tsawg, kev nqis peev yog txo, kev ua haujlwm thiab kev saib xyuas yog yooj yim 2} skid{{ yooj yim, adaptability muaj zog, thiab cov khoom roj purity tuaj yeem hloov kho raws li qhov xav tau. Los ntawm techno-kev xav txog kev lag luam, PSA ua tau zoo tshaj txoj kev cryogenic hauv cov khoom siv nitrogen uas muaj peev xwm tsawg dua 3000 Nm³ / hr. Rau chav nyob nrog lub peev xwm ntawm 1000 Nm³ / hr lossis qis dua,PSA nitrogen generatorcov cuab yeej muaj kev sib tw heev thiab nrov ntawm cov me thiab nruab nrab - cov neeg siv loj.
3. Membrane sib cais
Membrane sib cais huab cua sib cais yog qhov siab - thev naus laus zis tsim tawm txawv teb chaws hauv xyoo 1980s, koom nrog cov khoom siv polymer. Nws yog ib qho ntawm kaum siab tshaj - thev naus laus zis kev lag luam ntawm lub xyoo pua 21st, thiab muaj cov lus hais thoob ntiaj teb: "Leej twg masters membrane technology tuav lub neej yav tom ntej ntawm kev lag luam tshuaj." Txawm hais tias nws pib lig, nws tau tsim kho sai thiab tau nce qib hauv Suav teb tsuas yog xyoo tas los no.
Lub hauv paus ntsiab lus ntawmmembrane cais nitrogen tiamyog siv huab cua raws li cov khoom siv raw: nyob rau hauv ib qho kev siab, oxygen thiab nitrogen yog sib cais los ntawm lawv qhov sib txawv permeation tus nqi los ntawm hollow fiber membrane. Piv nrog rau ob txoj hauv kev, membrane sib cais nitrogen tiam muaj qhov zoo xws li cov qauv siv yooj yim dua, ntim me dua, tsis muaj qhov hloov pauv, kev ua haujlwm yooj yim dua thiab kev saib xyuas, kev tsim roj sai dua, thiab kev nthuav dav yooj yim. Txawm li cas los xij, hollow fiber ntau daim nyias nyias muaj kev huv dua rau cov cua compressed; lawv cov ntsiab lus lim yog qhov ua rau muaj kev laus thiab corrosion (ua rau tsis ua haujlwm, uas feem ntau tsis tuaj yeem hloov pauv, yuav tsum tau hloov daim nyias nyias). Tam sim no, hollow fiber ntau yuav tsum tau tuaj ntawm txawv teb chaws, ua rau lawv kim.
Membrane sib cais nitrogen tiam yog tsim rau me me thiab nruab nrab- cov neeg siv nitrogen loj uas xav tau nitrogen purity Tsawg dua lossis sib npaug li 98%, muab tus nqi zoo - ua haujlwm piv. Txawm li cas los xij, thaum nitrogen purity siab tshaj 98% yuav tsum tau, nws cov nqi yog kwv yees li 30% siab dua li ntawm PSA units ntawm tib lub ntsiab lus.
Hauv cov ntsiab lus, thaum sib piv cov yam xws li kev tsim khoom, kev yooj yim ntawm kev teeb tsa / kev ua haujlwm / kev tu, thiab kev tsim khoom / ua haujlwm cov nqi,PSA nitrogen generatormuaj qhov zoo xws li kev nqis peev tsawg, kev ua haujlwm yooj yim, kev saib xyuas yooj yim, thiab kev siv hluav taws xob tsawg.
