Ama-molecule e-nitrogen anezinga lokusabalalisa ngokushesha kuma-micropores we-zeolite molecular sieve, futhi ama-molecule omoya-mpilo anezinga lokusabalalisa elihamba kancane.Ukusatshalaliswa kwamanzi ne-carbon dioxide emoyeni ocindezelwe kufana nalokho kwe-nitrogen.Ekugcineni, ama-molecule e-oksijini ayacetshiswa embhoshongweni we-adsorption.I-pressure swing adsorption ukukhiqizwa komoya-mpilo kusebenzisa izici ezikhethiwe zokukhangisa ze-zeolite molecular sieve, yamukela umjikelezo wokukhangisa okucindezelwe kanye ne-decompression desorption, futhi yenza umoya ocindezelwe ungene embhoshongweni we-adsorption ngokushintshana ukuze ubone ukuhlukaniswa komoya-mpilo ne-nitrogen, ukuze uqhubeke ukhiqiza okuphezulu. - ubumsulwa kanye ne-oxygen yekhwalithi ephezulu.
Ijeneretha ye-oxygen ye-PSA yamukela i-zeolite yekhwalithi ephezulu njenge-adsorbent ngokuya ngomgomo we-press swing adsorption.Ngaphansi kwengcindezi ethile, umoya-mpilo ukhishwa emoyeni, umoya ocindezelwe ohlanziwe futhi omisiwe, futhi i-adsorption ecindezelayo kanye ne-decompression desorption yenziwa ku-adsorber.Ngenxa yomphumela we-aerodynamic, izinga lokusatshalaliswa kwe-nitrogen kuma-micropores we-zeolite molecular sieve liphezulu kakhulu kunelomoya-mpilo.I-nitrogen ithandwa kakhulu ngesisefo se-molecular ye-zeolite, futhi umoya-mpilo uyacetshiswa esigabeni segesi ukuze kwakheke umoya-mpilo ophelile.Khona-ke, ngemva kokuwohloka kokucindezela komkhathi, isisefo semolekyuli sisusa initrogen ekhangisiwe nokunye ukungcola ukuze kubonakale ukuvuselelwa.Ngokuvamile, imibhoshongo emibili ye-adsorption isethwe ohlelweni, enye i-adsorption kanye nokukhiqizwa kwe-oxygen, kanti enye i-desorption nokuvuselela.Isilawuli sohlelo lwe-PLC silawula ukuvulwa nokuvalwa kwe-valve ye-pneumatic ukwenza imibhoshongo emibili ijikeleze ngokushintshana, ukuze kuzuzwe inhloso yokukhiqiza okuqhubekayo komoya-mpilo wekhwalithi ephezulu.
