Cov ntsiab lus tseem ceeb ntawm huab cua yog nitrogen (78%) thiab oxygen (21%), yog li nws tuaj yeem hais tias huab cua yog qhov tsis txaus rau kev npaj nitrogen thiab oxygen.PSA oxygen cog.Nitrogen feem ntau yog siv rau hluavtaws ammonia, hlau kho cua sov tiv thaiv huab cua, inert tiv thaiv roj hauv tshuaj lom neeg ntau lawm (pib thiab kaw cov kav dej purging, nitrogen sealing yooj yim oxidized tshuaj), grain cia, txiv hmab txiv ntoo preservation, hluav taws xob kev lag luam, thiab lwm yam. Oxygen yog Feem ntau yog siv los ua oxidant hauv metallurgy, auxiliary gas, kev kho mob, kev kho dej khib nyiab, siab viav vias adsorption nitrogen cog thiab tshuaj lom neeg kev lag luam.Yuav ua li cas pheej yig cais huab cua los tsim cov pa oxygen thiab nitrogen yog qhov teeb meem mus sij hawm ntev kawm thiab daws los ntawm cov kws tshuaj.
Ntshiab nitrogen tsis tuaj yeem muab rho tawm ncaj qha los ntawm qhov xwm txheej, yog li kev sib cais huab cua yog thawj qhov kev xaiv.Txoj kev sib cais huab cua muaj xws li cov txheej txheem kub qis, siab viav vias adsorption txoj kev thiab txoj kev sib cais membrane.Nrog rau kev loj hlob sai ntawm kev lag luam, nitrogen tau siv dav hauv kev lag luam chemical, electronics, metallurgy, khoom noj khoom haus, tshuab thiab lwm yam.Tuam Tshoj qhov kev thov rau nitrogen yog loj hlob ntawm ib xyoos twg ntawm ntau tshaj 8%.Lub chemistry ntawm nitrogen tsis yog tiag tiag.Nws yog inert heev nyob rau hauv tej yam kev mob zoo tib yam thiab tsis yooj yim rau react nrog lwm yam tshuaj.Yog li ntawd, nitrogen yog dav siv raws li kev kho Gas thiab sealing gas nyob rau hauv metallurgy, electronics, tshuaj lom neeg kev lag luam thiab lwm yam lag luam.Feem ntau hais lus, purity ntawm kev tu roj yog 99.99%, thiab qee qhov xav tau ntau tshaj 99.998% high-purity nitrogen.
Kua nitrogen generator yog ib qho yooj yim txias qhov chaw, uas yog ntau thiab ntau lug siv nyob rau hauv cov phev cia nyob rau hauv cov khoom noj khoom haus kev lag luam, kev ua hauj lwm thiab tsiaj txhu.Hauv kev tsim cov khoom siv hluavtaws ammonia hauv kev lag luam chiv, hydrogen nitrogen sib xyaw hauv cov khoom siv ammonia pub roj yog ntxuav thiab ua kom zoo nrog cov kua nitrogen ntshiab.Cov ntsiab lus ntawm inert gas tej zaum yuav tsawg heev, thiab cov ntsiab lus ntawm carbon monoxide thiab oxygen yuav tsum tsis txhob ntau tshaj 20ppm.
Kev sib cais ntawm daim nyias nyias ntawm cov huab cua tau txais lub hauv paus ntsiab lus ntawm permeation, uas yog, qhov sib txawv ntawm cov pa oxygen thiab nitrogen nyob rau hauv nonporous polymer membrane yog txawv.Thaum cov pa oxygen thiab nitrogen yog adsorbed rau ntawm qhov chaw ntawm cov ntaub ntawv polymer, vim tias qhov concentration gradient ntawm ob sab ntawm daim nyias nyias, cov roj tau diffuses thiab dhau los ntawm cov ntaub ntawv polymer, thiab tom qab ntawd desorbs ntawm lwm sab ntawm daim nyias nyias.Vim tias qhov ntim ntawm cov pa oxygen molecule tsawg dua li ntawm nitrogen molecule, qhov diffusion tus nqi ntawm cov pa hauv polymer membrane yog ntau dua li ntawm nitrogen molecule.Nyob rau hauv txoj kev no, thaum huab cua nkag mus rau ib sab ntawm daim nyias nyias, oxygen enriched cua tuaj yeem tau ntawm sab nraud thiab nitrogen tuaj yeem tau ntawm tib sab.
Nitrogen thiab oxygen enriched cua tuaj yeem tau txais tsis tu ncua los ntawm kev sib cais huab cua nrog cov txheej txheem membrane.Tam sim no, kev xaiv coefficient ntawm polymer membrane rau oxygen thiab nitrogen sib cais tsuas yog li 3.5, thiab cov permeability coefficient kuj tsawg heev.Cov nitrogen concentration ntawm cov khoom sib cais yog 95 ~ 99%, thiab cov pa oxygen tsuas yog 30 ~ 40%.Membrane sib cais ntawm huab cua feem ntau yog nqa tawm ntawm chav tsev kub, 0.1 ~ 0.5 × 106pa.
