Isimiso sokukhiqizwa kwe-nitrogen ye-PSA
I-diameter yama-molecule e-oksijini incane kunaleyo yama-molecule e-nitrogen, ngakho-ke isivinini sokusabalalisa sishesha izikhathi ezingamakhulukhulu kune-nitrogen, ngakho-ke ijubane le-carbon molecular sieve adsorption of oxygen liyashesha kakhulu, ukukhanga cishe umzuzu owodwa ukuze kufinyelele ngaphezu kwalokho. 90%;Kuleli qophelo, i-nitrogen adsorption cishe i-5% kuphela, ngakho-ke ngokuvamile i-oxygen, kanti enye ingxenye enkulu ye-nitrogen.Ngale ndlela, uma isikhathi se-adsorption silawulwa ngaphakathi kweminithi elingu-1, i-oxygen ne-nitrogen ingahlukaniswa ekuqaleni, okungukuthi, i-adsorption kanye ne-desorption ifinyelelwa ngokuhlukana kwengcindezi, ingcindezi iyanda lapho i-adsorption, ingcindezi iyancipha lapho i-desorption.Umehluko phakathi kwe-oxygen ne-nitrogen ubonakala ngokulawula isikhathi se-adsorption, esifushane kakhulu.I-oksijeni isikhangisiwe ngokugcwele, kuyilapho i-nitrogen ingazange ibe nesikhathi sokukhangisa, ngakho imisa inqubo yokukhanga.Ngakho-ke, ingcindezi swing adsorption ukukhiqizwa nitrogen ukuba kube nengcindezi izinguquko, kodwa futhi ukulawula isikhathi phakathi 1 iminithi.

Izici Zomkhiqizo
Imishini yokukhiqiza i-nitrogen ye-molecular Ukuthembeka okuphezulu, ukusebenza okuphezulu kanye nezindleko eziphansi zokusebenza Ukusebenzela umhlaba cishe iminyaka engama-20
Kutholwe inombolo yobuchwepheshe obunelungelo lobunikazi obuphelele kusixazululo sokukhiqiza igesi esizeni
Ukonga Amandla kufika ku-10% ~ 30%
Iminyaka engu-20 yokugxila ocwaningweni lomkhiqizo nasekuthuthukisweni nasekusetshenzisweni, enobuchwepheshe abambalwa obunelungelo lobunikazi, ukukhetha kwe-adsorbent yekhwalithi ephezulu, ukusebenza okuphezulu kokulawulwa kohlelo okonga kufikela ku-10% ~ 30%
Impilo yenkonzo yeminyaka eyishumi
Umshini wonke uklanyelwe futhi usetshenziswe iminyaka engu-10. Imikhumbi yokucindezela, ama-valve ahleliwe, amapayipi, izihlungi nezinye izingxenye eziyinhloko zesiqinisekiso sekhwalithi yeminyaka engu-20.
Ukuklama okuqinile kwezimo zohlelo lokusebenza
Ngaphansi kwezimo ezilandelayo, isisetshenziswa sokwenza i-nitrogen sisebenza ngokuzinza nangokuqhubekayo sigcwele ngokugcwele.
Izinga lokushisa le-ambient: -20 ° C kuya +50 ° C
Umswakamo we-ambient: ≤95%
Umfutho wegesi omkhulu: 80kPa ~ 106kPa
Qaphela: ingaklanywa ngokukhethekile kulezi zimo zokusebenza ezingenhla
Ukufakwa kalula nokugcinwa
Idizayini yesimanje yezimboni eqinile futhi enengqondo, ukumodela okulungiselelwe, ubuchwepheshe obuhle, uma kuqhathaniswa nezinye izinto zokukhiqiza i-nitrogen inokwethenjelwa okuphezulu, umjikelezo wenkonzo omude, ukufakwa kwemishini kuhlanganisa indawo encane, ukufakwa kalula nokugcinwa.
