Fotokozani mwachidule ntchito ya PSA nitrogen jenereta?

Pogwiritsa ntchito mpweya woponderezedwa ngati zopangira, imagwiritsa ntchito adsorbent yotchedwa carbon molecular sieve kuti iwononge nayitrogeni ndi mpweya kuti ilekanitse nayitrogeni mumlengalenga.Kupatukana kwa sieve ya carbon molecular pa nayitrogeni ndi okosijeni makamaka kumatengera kufalikira kwa ma molekyulu a nayitrogeni ndi okosijeni pamwamba pa sieve ya maselo.Mamolekyu a okosijeni okhala ndi mainchesi ang'onoang'ono amafalikira mwachangu ndikulowa mugawo lolimba la sieve ya maselo;mamolekyu a nayitrogeni okhala ndi mainchesi okulirapo amafalikira Pang'onopang'ono komanso pang'ono kulowa mu gawo lolimba la sieve ya maselo, kotero kuti nayitrogeni amalemeretsedwa mu gawo la mpweya.

Patapita nthawi, sieve ya molekyulu imatha kuyamwa mpweya mpaka kufika pamlingo wina wake.Kupyolera mu decompression, mpweya wotulutsidwa ndi carbon molecular sieve umatulutsidwa, ndipo sieve ya maselo imapangidwanso.Izi zimachokera ku chikhalidwe chakuti ma sieve a maselo ali ndi mphamvu zosiyana za adsorption kwa mpweya wa adsorbed pansi pa zovuta zosiyanasiyana.Pressure swing adsorption nayitrogeni kupanga zida nthawi zambiri zimagwiritsa ntchito ma adsorbers awiri ofanana, mosinthana ndikuchita kutsatsira ndikutsitsimutsanso, ndipo nthawi yozungulira ndi pafupifupi mphindi ziwiri.
