Jenereta ya nayitrogeni ndiukadaulo wapamwamba wolekanitsa gasi.Sieve yapamwamba kwambiri yotchedwa carbon molecular sieve (CMS) imagwiritsidwa ntchito ngati adsorbent, ndipo mpweya wa nayitrogeni woyeretsedwa kwambiri umakonzedwa polekanitsa mpweya pa kutentha kwabwino pansi pa mfundo ya pressure swing adsorption (PSA).
Kufalikira kwa ma molekyulu a okosijeni ndi mpweya wa nayitrogeni pamwamba pa sieve ya maselo ndi osiyana.Mamolekyu agasi okhala ndi ma diameter ang'onoang'ono (O2) amakhala ndi liwiro lofalikira mwachangu, ma micropores ochulukirapo omwe amalowa mu sieve ya carbon molecular, komanso kuchuluka kwa ma molekyulu akulu a gasi (N2).Pang'onopang'ono, pali ma micropores ochepa omwe amalowa mu sieve ya carbon molecular.Kusiyana kosankha kwa adsorption pakati pa nayitrogeni ndi okosijeni ndi sieve ya carbon molecular kumabweretsa kukulitsa kwa okosijeni mu gawo la adsorption pakanthawi kochepa, kukulitsa nayitrogeni mu gawo la mpweya, kotero kuti mpweya ndi nayitrogeni zimalekanitsidwa, ndipo gawo la mpweya limalemeretsedwa. nitrogen imapezeka pansi pa chikhalidwe cha PSA.
Patapita nthawi, kuyamwa kwa okosijeni ndi sieve ya maselo kumakhala koyenera.Malinga ndi kusiyanasiyana kwa ma adsorption mphamvu ya sieve ya carbon molecular to the adsorbed gasi pansi pa zipsinjo zosiyanasiyana, kukakamizidwa kumatsitsidwa kuti athetse sieve ya carbon molecular, ndipo ndondomekoyi ndi kusinthika.Malinga ndi kukakamizidwa kosiyanasiyana kosinthika, kumatha kugawidwa kukhala kusinthika kwa vacuum ndi kusinthika kwapamlengalenga.Kusinthika kwa mumlengalenga kumathandizira kusinthika kwathunthu kwa ma sieve a maselo, kupangitsa kuti zikhale zosavuta kupeza mpweya wabwino kwambiri.
The pressure swing adsorption nitrogen jenereta (yotchedwa PSA nayitrogeni jenereta) ndi chipangizo chopangira nayitrogeni chopangidwa ndikupangidwa molingana ndi ukadaulo wa kuthamanga kwa adsorption.Nthawi zambiri, nsanja ziwiri za adsorption zimalumikizidwa molumikizana, ndipo makina owongolera okhawo amawongolera nthawiyo motsatira ndondomeko yokhazikika, mosinthana imachita kutsatsa komanso kusinthika kwapang'onopang'ono, kumamaliza kupatukana kwa nayitrogeni ndi okosijeni, ndikupeza mpweya wa nayitrogeni woyeretsa kwambiri.
