Isimiso sokukhiqizwa kwe-nitrogen ye-PSA
Isisefo samangqamuzana ekhabhoni singakhanga umoya-mpilo kanye ne-nitrogen kanye kanye emoyeni, futhi amandla ayo okukhangisa nawo anda ngokunyuka kwengcindezi, futhi awukho umehluko osobala kumthamo wokulinganisa wokulinganisa we-oxygen ne-nitrogen ngaphansi kwengcindezi efanayo. Ngakho-ke, kunzima ukufeza ukuhlukaniswa okuphumelelayo kwe-oxygen ne-nitrogen kuphela ngoshintsho lwengcindezi. Uma isivinini se-adsorption sicatshangelwa futhi, izakhiwo ze-adsorption zomoya-mpilo ne-nitrogen zingahlukaniswa ngempumelelo. 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 ukufinyelela ngaphezu kwalokho. 90%; Kuleli qophelo, i-nitrogen adsorption cishe i-5% kuphela, ngakho-ke i-oxygen eningi, kanti enye ingxenye enkulu ye-nitrogen. Ngale ndlela, uma isikhathi sokukhangisa silawulwa ngaphakathi kweminithi elingu-1, i-oxygen ne-nitrogen ingahlukaniswa ekuqaleni, okungukuthi, i-adsorption 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.
I-1- Air compressor; 2- isihlungi; 3 - isomisi; 4-isihlungi; Umbhoshongo wokukhangisa we-5-PSA; 6- isihlungi; 7- Ithangi le-nitrogen buffer
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 Isixazululo sokukhiqiza igesi esiphelele esizeni
Ukonga Amandla kufika ku-10% ~ 30%
Iminyaka engu-20 yokugxila ocwaningweni lomkhiqizo nasekuthuthukisweni nasekusetshenzisweni, ngobuchwepheshe abambalwa obunelungelo lobunikazi, ukukhetha kwe-adsorbent yekhwalithi ephezulu, ukusebenza okuphezulu kokulawulwa kohlelo okonga kufika 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.
Idizayini eqinile yemibandela yohlelo lokusebenza
Ngaphansi kwezimo ezilandelayo, isisetshenziswa sokwenza i-nitrogen sisebenza ngokuzinzile futhi ngokuqhubekayo 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 wesevisi omude, ukufakwa kwemishini kuhlanganisa indawo encane, ukufakwa kalula nokugcinwa.
