Ijeneretha ye-nitrogen iwubuchwepheshe obuphambili bokuhlukanisa igesi.Isisefo se-carbon molecular molecular (CMS) sekhwalithi ephezulu sisetshenziswa njenge-adsorbent, futhi igesi ye-nitrogen ehlanzekile kakhulu ilungiswa ngokuhlukanisa umoya ezingeni lokushisa elivamile ngaphansi komgomo we-pressure swing adsorption (PSA).
Amazinga okusabalalisa ama-molecule e-oxygen negesi ye-nitrogen ebusweni besisefo samangqamuzana ahlukile.Amangqamuzana egesi anobubanzi obuncane (O2) anezinga lokusabalalisa ngokushesha, ama-micropore amaningi angena kusisefo se-carbon molecular, kanye nezinga lokusabalalisa lama-athomu amakhulu egesi (N2).Kancane kancane, kukhona ama-micropores ambalwa angena kusihlungo se-carbon molecular.Umehluko okhethiwe we-adsorption phakathi kwe-nitrogen nomoya-mpilo ngesisefo se-carbon molecular sieve uholela ekuthuthukisweni komoya-mpilo esigabeni se-adsorption ngesikhathi esifushane, ukunothiswa kwe-nitrogen esigabeni segesi, ukuze kuhlukaniswe umoya-mpilo ne-nitrogen, futhi isigaba segesi sinothiswe. i-nitrogen itholakala ngaphansi kwesimo se-PSA.
Ngemva kwesikhathi esithile, ukungeniswa komoyampilo ngesisefo samangqamuzana kuyalinganisela.Ngokomthamo we-adsorption ohlukile we-carbon molecular sieve kuya kugesi ekhangisiwe ngaphansi kwengcindezi ehlukene, ingcindezi iyehliswa ukuze yenze isisefo se-carbon molecular sieve, futhi inqubo iwukuvuselelwa kabusha.Ngokusho kwengcindezi ehlukene yokuvuselela, ingahlukaniswa ibe ukuvuselelwa kwe-vacuum kanye nokuvuselelwa kabusha kwengcindezi yasemkhathini.Ukuvuselelwa kwe-atmospheric kusiza ukuvuselelwa okuphelele kwezisefo zamangqamuzana, okwenza kube lula ukuthola amagesi ahlanzekile aphezulu.
Ijeneretha ye-press swing adsorption nitrogen generator (ebizwa ngokuthi i-PSA nitrogen generator) iyithuluzi elikhiqiza i-nitrogen elaklanywa futhi lakhiqizwa ngokuya ngobuchwepheshe be-press swing adsorption.Ngokuvamile, le mibhoshongo yokukhangisa emibili ixhunywe ngokuhambisana, futhi uhlelo lokulawula oluzenzakalelayo lulawula ngokuqinile isikhathi ngokulandelana okuthile okuhlelekayo, ngokushintshana lwenza i-adsorption yokucindezela kanye nokuvuselelwa kabusha kokucindezela, luqedele ukuhlukaniswa kwe-nitrogen nomoya-mpilo, futhi ithola igesi ye-nitrogen ehlanzekile kakhulu.
