PSA pressure swing adsorption nayitrogeni kupanga njira nayitrogeni mfundo

Mpweya wa carbon molecular ukhoza kuyamwa mpweya ndi nayitrogeni mumlengalenga nthawi yomweyo, ndipo mphamvu yake ya adsorption imawonjezekanso ndi kuwonjezeka kwa kuthamanga, ndipo panthawi yomweyi mphamvu ya okosijeni ndi nitrogen equilibrium adsorption ilibe kusiyana koonekeratu.Choncho, n'zovuta kukwaniritsa kulekana kwa mpweya ndi nayitrogeni kokha ndi kusintha kwamphamvu.Ngati kuganiziridwa kwina kumaperekedwa pamitengo ya adsorption, ma adsorption a oxygen ndi nitrogen amatha kusiyanitsa bwino.M'mimba mwake mamolekyu a okosijeni ndi ang'onoang'ono kuposa mamolekyu a nayitrogeni, motero kuchuluka kwa magawanidwe kumachulukana mwachangu kuposa nayitrogeni, ndiye kuti kuthamanga kwa mpweya wa cell molecular sieve adsorption wa okosijeni ndikothamanga kwambiri, kutengera pafupifupi mphindi 1 kuti mufikire zambiri. kuposa 90%;Panthawiyi, kuchuluka kwa nitrogen adsorption ndi pafupifupi 5%, kotero kuti adsorption nthawi zambiri imakhala mpweya, ndipo ena ambiri ndi nayitrogeni.Mwanjira iyi, ngati nthawi ya adsorption ikuyendetsedwa mkati mwa miniti ya 1, mukhoza poyamba kulekanitsa mpweya ndi nayitrogeni, ndiko kuti, kutsekemera ndi kutsekemera kumatheka chifukwa cha kusiyana kwa kuthamanga, pamene kupanikizika kumawonjezera kutsekemera, kutsekemera pamene kuthamanga kutsika.Kusiyanitsa pakati pa okosijeni ndi nayitrogeni kumachokera ku kusiyana kwa liwiro la adsorption pakati pa ziwirizi, kupyolera mu kulamulira kwa nthawi ya adsorption kuti akwaniritse, nthawi yolamulira ndi yochepa kwambiri, mpweya wakhala ukugwiritsidwa ntchito bwino, ndipo nayitrogeni sinakhalepo ndi nthawi yoti adsorption, anasiya. ndondomeko ya adsorption.Chifukwa chake, kusintha kwamphamvu ndi kuwongolera nthawi pakupanga nayitrogeni pogwiritsa ntchito kuthamanga kwa ma swing adsorption kuyenera kukhala mkati mwa mphindi imodzi.
