PSA uxinzelelo ujingi adsorption nitrogen umgaqo wokuvelisa initrogen
I-Carbon molecular sieve inokufunxa i-oksijini kunye ne-nitrogen emoyeni ngaxeshanye, kwaye amandla ayo okukhangisa nawo ayanda ngokunyuka koxinzelelo, kwaye kuxinzelelo olufanayo lwe-oxygen kunye ne-nitrogen equilibrium adsorption umthamo awunamahluko ocacileyo.Ngoko ke, kunzima ukugqiba ukwahlula okusebenzayo kwe-oksijeni kunye ne-nitrogen kuphela ngokutshintshwa koxinzelelo.Ukuba ingqwalasela eyongezelelweyo inikwe kumazinga e-adsorption, iimpawu ze-adsorption ze-oksijini kunye ne-nitrogen zinokwahlulwa ngokufanelekileyo.Idayamitha yeemolekyuli zeoksijini incinci kuneemolekyuli zenitrogen, ngoko ke izinga lokusasazwa likhawuleza kangangamakhulu amaxesha kunolo lwenitrogen, ngoko ke isantya secarbon molecular sieve adsorption yeoksijini sikwakhawuleza kakhulu, i-adsorption yemizuzu eyi-1 ukufikelela ngaphezulu. ngaphezu kwama-90%;Ngeli xesha, inani le-nitrogen adsorption limalunga ne-5% kuphela, ngoko ke i-adsorption ininzi i-oxygen, kwaye enye ininzi i-nitrogen.Ngale ndlela, ukuba ixesha le-adsorption lilawulwa ngaphakathi kwe-1 ngomzuzu, unokuqala ukwahlula i-oksijini kunye ne-nitrogen, oko kukuthi, i-adsorption kunye ne-desorption ifezekiswa ngokuhlukana koxinzelelo, xa uxinzelelo lwandisa i-adsorption, i-desorption xa uxinzelelo lwehla.Ukwahlula phakathi kwe-oksijini kunye ne-nitrogen isekelwe kumahluko wesantya se-adsorption phakathi kwezi zibini, ngokulawulwa kwexesha le-adsorption ukufezekisa, ulawulo lwexesha lufutshane kakhulu, i-oksijini sele idsorbed ngokupheleleyo, kwaye i-nitrogen ayikabi nalo ixesha lokubhengezwa. inkqubo ye-adsorption.Ke ngoko, utshintsho loxinzelelo kunye nolawulo lwexesha lokuveliswa kwenitrogen ngoxinzelelo lwe-adsorption swing kufuneka lube ngaphakathi komzuzu omnye.
