PSA siab viav vias adsorption nitrogen ntau lawm mechanism nitrogen txoj cai

Cov pa roj carbon molecular sieve tuaj yeem nqus cov pa thiab nitrogen hauv huab cua tib lub sijhawm, thiab nws lub peev xwm adsorption kuj nce nrog kev nce siab, thiab tib lub siab oxygen thiab nitrogen equilibrium adsorption muaj peev xwm tsis muaj qhov txawv txav.Yog li ntawd, nws yog ib qho nyuaj rau ua kom tiav cov kev sib cais ntawm cov pa oxygen thiab nitrogen tsuas yog los ntawm kev hloov siab.Yog tias xav tau ntxiv rau cov nqi adsorption, cov khoom adsorption ntawm oxygen thiab nitrogen tuaj yeem paub qhov txawv.Txoj kab uas hla ntawm oxygen molecules yog me dua li ntawm nitrogen molecules, yog li qhov diffusion tus nqi yog ntau pua lub sij hawm sai dua li ntawm nitrogen, yog li qhov ceev ntawm carbon molecular sieve adsorption ntawm oxygen kuj ceev heev, adsorption ntawm li 1 feeb mus cuag ntau dua. ntau tshaj 90%;Lub sijhawm no, tus nqi ntawm nitrogen adsorption tsuas yog kwv yees li 5%, yog li cov adsorption feem ntau yog oxygen, thiab cov seem feem ntau yog nitrogen.Nyob rau hauv txoj kev no, yog tias lub sij hawm adsorption tswj tsis pub dhau 1 feeb, koj tuaj yeem pib cais cov pa oxygen thiab nitrogen, uas yog hais tias, adsorption thiab desorption tau tiav los ntawm qhov sib txawv siab, thaum lub siab nce adsorption, desorption thaum lub siab poob.Qhov sib txawv ntawm cov pa oxygen thiab nitrogen yog raws li qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, los ntawm kev tswj lub sij hawm adsorption kom ua tiav, lub sij hawm tswj tau luv heev, oxygen tau tag nrho adsorbed, thiab nitrogen tseem tsis tau muaj sij hawm rau adsorption, nres. cov txheej txheem adsorption.Yog li ntawd, kev hloov siab thiab lub sijhawm tswj kev tsim cov nitrogen los ntawm lub siab viav vias adsorption yuav tsum tsis pub dhau 1 feeb.
