PSA (Pressure Swing Adsorption) majenereta a nayitrogeni ndi machitidwe omwe amagwiritsidwa ntchito kupanga mpweya wa nayitrogeni poulekanitsa ndi mpweya. Amagwiritsidwa ntchito m'mafakitale osiyanasiyana ndikugwiritsa ntchito komwe kumafunikira nitrogen wokhazikika wa 99-99.999%.
Mfundo yofunikira ya aPSA nitrogen jeneretakumaphatikizapo kugwiritsa ntchito adsorption ndi desorption cycle. Umu ndi momwe zimagwirira ntchito:
Adsorption: Njirayi imayamba ndi mpweya wopanikizika womwe umadutsa m'chombo chomwe chili ndi zinthu zotchedwa molecular sieve. Sieve ya molekyulu imakhala yolumikizana kwambiri ndi mamolekyu okosijeni, kuwalola kuti azitha kuwatsatsa mosankha ndikulola kuti mamolekyu a nayitrogeni adutse.
Kupatukana kwa Nayitrojeni: Pamene mpweya woponderezedwa ukudutsa pa bedi la molekyulu ya sieve, mamolekyu a okosijeni amathamangitsidwa, ndikusiya mpweya wowonjezera nayitrogeni. Mpweya wa nayitrogeni umasonkhanitsidwa ndikusungidwa kuti ugwiritsidwe ntchito.
Desorption: Patapita nthawi, bedi la molecular sieve limakhala lodzaza ndi okosijeni. Panthawiyi, njira yowonongeka imayimitsidwa, ndipo kupanikizika mu chotengera kumachepetsedwa. Kuchepetsa kupanikizika kumeneku kumapangitsa kuti mamolekyu a okosijeni a adsorbed atulutsidwe mu sieve ya molekyulu, kuwalola kuti achotsedwe ku dongosolo.
Kubadwanso Kwatsopano: Oxygen ikatsukidwa, kupanikizika kumawonjezekanso, ndipo bedi la sieve la molekyulu likukonzekera kuzungulira kwina. Njira zosinthira ma adsorption ndi desorption zikupitiliza kutulutsa mpweya wa nayitrogeni mosalekeza.
PSA nitrogen jeneretaamadziwika chifukwa cha luso lawo komanso kudalirika. Amatha kupanga nayitrogeni wokhala ndi milingo yoyera kwambiri, kuyambira 95% mpaka 99.999%. Mulingo wachiyero womwe umakwaniritsidwa umadalira zofunikira zenizeni za ntchitoyo.
Majeneretawa amagwiritsidwa ntchito kwambiri m'mafakitale monga kunyamula chakudya, kupanga zamagetsi, mankhwala, kukonza mankhwala, mafuta ndi gasi, ndi ena ambiri. Amapereka maubwino monga kupanga nayitrogeni pamalo, kupulumutsa mtengo poyerekeza ndi njira zachikhalidwe zoperekera nayitrogeni, komanso kuthekera kosintha mayendedwe a nayitrogeni kutengera zosowa zenizeni.
