Nyob rau hauv cov txheej txheem ntawm kev tsim khoom, tshuaj lom thiab teeb meem, volatile, flammable thiab explosive cov ntaub ntawv yuav tsum tau tiv thaiv los ntawm inert gases.Nitrogen, raws li ib tug ntawm cov inert gases, muaj ib tug nplua nuj nyob rau hauv cov pa roj, nrog rau cov ntsiab lus ntawm 79% nyob rau hauv cov huab cua, thiab tau siv dav hauv ntau lawm.Tam sim no, cov cuab yeej ua ib leeg tau siv dav hauv kev tiv thaiv kev nyab xeeb roj, hloov roj, nitrogen txhaj peb zaug roj rov qab, thee mine hluav taws kev tiv thaiv thiab tua hluav taws, nitrogen raws huab cua kho cua sov, tiv thaiv corrosion thiab tawg-pov thawj, hluav taws xob kev lag luam, integrated circuit, thiab lwm yam.

Cov pa roj carbon molecular sieves thiab zeolite molecular sieves tau siv ntau dua hauv kev tsim cov nitrogen.Kev sib cais ntawm oxygen thiab nitrogen los ntawm molecular sieve feem ntau yog raws li qhov sib txawv ntawm qhov sib txawv ntawm ob lub gases nyob rau saum npoo ntawm molecular sieve.Cov pa roj carbon molecular sieve yog cov pa roj carbon-based adsorbent nrog qee cov yam ntxwv ntawm cov pa roj carbon activated thiab molecular sieve.Cov pa roj carbon molecular sieves yog tsim los ntawm cov pores me me.Cov pa roj me me diffuses sai dua thiab nkag mus rau theem khoom ntawm molecular sieve, kom cov nitrogen enrichment tivthaiv tuaj yeem tau txais hauv theem roj.Molecular sieve nitrogen yog cua raws li raw khoom, nrog carbon molecular sieve li adsorbent, siv lub hauv paus ntsiab lus ntawm kev hloov siab adsorption, siv cov pa roj carbon molecular sieve ntawm oxygen thiab nitrogen xaiv adsorption thiab sib cais ntawm nitrogen thiab oxygen txoj kev, feem ntau hu ua PSA nitrogen ntaus ntawv. .

Raws li adsorbent rau cov roj sib txawv hauv lub peev xwm adsorption thiab adsorption ceev, adsorption thiab lwm yam sib txawv, nrog rau cov adsorbent adsorption muaj peev xwm sib txawv nrog kev hloov siab, yog li PSA nitrogen ua cov cuab yeej tuaj yeem ua tiav hauv cov xwm txheej ntawm cov roj sib xyaw adsorption kev sib cais, txo lub siab desorption adsorption los ntawm impurity Cheebtsam, thiaj li kom paub txog cov recycling ntawm roj sib cais thiab adsorbent.

Hauv qee qhov kev lag luam tawm tshiab, kev lag luam hluav taws xob, kev sib koom ua ke, npias dej haus thiab lwm yam kev siv roj inert kuj tseem nthuav dav daim ntawv thov tshiab.Piv txwv li, lub tshiab PSA nitrogen ntau lawm ntaus ntawv tau siv rau inert kev tiv thaiv ntawm lub xov tooj ntawm tes lithium roj teeb ntau lawm, nitrogen ntim rau npias thiab dej haus, nitrogen dehydration thiab ziab nyob rau hauv organosilicone ntau lawm, thiab nitrogen ntim rau khoom noj txom ncauj es tsis txhob ntawm huab cua thiab deoxidizer.Daim ntawv thov ntawm nitrogen ua rau cov khoom ntawm cov lag luam hauv cov txheej txheem thev naus laus zis, cov khoom lag luam tau raug txhim kho, kom yeej qhov kev sib tw tseem ceeb.
