Pressure swing adsorption nitrogen kugadzirwa
inoshandisa mhepo seyakagadzirwa, carbon molecular sieve seye adsorbent, uchishandisa musimboti wekumanikidza swing adsorption, kushandiswa kwekabhoni molecular sieve kusarudza adsorb okisijeni nenitrogen kuparadzanisa nitrogen neokisijeni, inowanzozivikanwa sePSA nitrogen.Iyi nzira ndiyo tekinoroji nyowani yekugadzira nitrogen yakakurumidza kukura muma1970.Kuenzaniswa neyechinyakare nzira yekugadzira nitrogen, ine zvakanakira kuyerera kwakapfava, yakakwira dhigirii ye otomatiki, kukurumidza kugadzira gasi (15-30 maminetsi), kuderera kwesimba rekushandisa, kuchena kwechigadzirwa kunogona kugadziridzwa muhukuru hwakakura zvichienderana nezvinodiwa nemushandisi, kushanda nekugadzirisa zviri nyore, uye kushanda Nehunhu hwemutengo wakaderera uye kuchinjika kwakasimba, inonyatso kukwikwidza mumidziyo yekugadzira nitrogen iri pasi pe1000Nm3/h, uye iri kuwedzera kufarirwa nevashandisi vadiki nepakati nitrogen.PSA nitrogen kugadzira yave sarudzo yekutanga kune diki nepakati nitrogen vashandisi nzira.
Cryogenic Air Separation Nitrogen
Cryogenic nitrogen kugadzirwa nekuparadzaniswa kwemhepo itsika yekugadzira nitrogen ine nhoroondo yemakumi emakore akati wandei.Inoshandisa mhepo seyakagadzirwa, yakamanikidzwa uye yakacheneswa, uyezve inoshandisa kupisa kuchinjanisa kunyungudutsa mweya mumhepo yemvura.Mhepo Liquide inonyanya musanganiswa weokisijeni yemvura uye nitrogen yemvura, uchishandisa mapoinzi akasiyana emvura okisijeni uye mvura nitrogen (pa1 mhepo, nzvimbo yekuvira yepakutanga i -183 ° C, uye yekupedzisira i -196 ° C) , kuburikidza nekugadzirisa kweLiquid Air, Vaparadzanise kuti vawane nitrogen.Cryogenic mhepo yekuparadzanisa nitrogen kugadzira michina yakaoma, inovhara nzvimbo hombe, yakakwira mitengo yezvivakwa, yakawanda-nguva imwe chete yekudyara midziyo, mutengo wakakwira wekushandisa, inononoka kugadzira gasi (12-24h), yakakwirira yekuisa zvinodiwa, uye kutenderera kwakareba.Yakakwana midziyo, kuisirwa uye zvivakwa zvinhu, midziyo iri pazasi 3500Nm3/h, chiyero chekudyara chePSA mudziyo weiyo yakafanana dhizaini iri 20% -50% yakaderera pane yeiyo cryogenic mhepo yekuparadzanisa mudziyo.Cryogenic air separation nitrogen kugadzirwa kwemidziyo yakakodzera kugadzirwa kwakakura kwemaindasitiri nitrogen, nepo kugadzirwa kwepakati uye diki nitrogen haina hupfumi.
Membrane Air Separation Nitrogen Production
Kushandisa mhepo seyakagadzirwa, pasi pemamwe mamiriro ekumanikidzwa, kushandiswa kweokisijeni nenitrogen uye mamwe magasi ane akasiyana midziyo mu membrane ane akasiyana permeation mitengo yekuparadzanisa okisijeni nenitrogen.Kana ichienzaniswa nemimwe michina yekugadzira nitrogen, ine zvakanakira chimiro chakareruka, vhoriyamu diki, isina switching valve, kushomeka kugadzirisa, kukurumidza kugadzira gasi (≤3 maminetsi), uye nyore kuwedzera kugona.Iyo inonyanya kukodzera kuchena kwe nitrogen ≤ 98% yevashandisi vepakati uye vashoma nitrogen vane yakanakisa mutengo-kune-basa reshiyo.Kana hutsanana hwenitrogen huri pamusoro pe98%, mutengo wayo unodarika 15% yakakwirira kudarika PSA nitrogen jenareta yezvakatsanangurwa zvakafanana.
