Mhando dzekugadzira nitrojeni dzinosanganisira kudzvanya swing adsorption, membrane kupatsanurwa uye cryogenic mhepo kupatsanurwa.Nitrogen jenareta chigadzirwa chenitrogen chakagadzirwa uye kugadzirwa zvinoenderana nekumanikidza swing adsorption tekinoroji.Muchina wenitrogen unoshandisa yakakwira-mhando yekunze kabhoni molecular sieve seadsorbent uye inoshandisa musimboti wekamuri tembiricha yekumanikidza swing adsorption kuparadzanisa mweya kuburitsa yakakwira-kuchena nitrogen.Kazhinji, maviri adsorption shongwe akabatanidzwa mukufanana, uye iyo inotengeswa kunze kwenyika PLC inodzora otomatiki mashandiro eiyo kunze kwenyika pneumatic valve kuita neimwe nzira kuita yakadzvanywa adsorption uye decompression regeneration kuti ipedze nitrogen neokisijeni kupatsanurwa uye kuwana inodiwa yakakwirira-kuchena nitrogen.
Nzira yekutanga ndeyekugadzira nitrogen ne cryogenic process
Iyi nzira inotanga kudzvanya nekutonhodza mhepo, yobva yanyungudutsa mweya.Uchishandisa mapoinzi akasiyana ekuvira eokisijeni nenitrogen zvinoumba, gasi uye mvura kusangana patireyi yekoramu yedistillation yehuwandu nekutsinhana kwekupisa.Okisijeni ine nzvimbo yekubikira yakakwira inoramba yakanyungudutswa kubva muutsi ichienda mumvura, uye iyo nitrogen ine nzvimbo yakaderera yekubikira inoramba ichiendeswa kumhepo, kuitira kuti iyo nitrogen iri mumhepo inokwira irambe ichiwedzerwa, nepo okisijeni iri pasi perwizi. mvura yakakwirira uye yakakwirira.Naizvozvo, okisijeni nenitrogen zvinopatsanurwa kuwana nitrogen kana oxygen.Iyi nzira inoitwa pakudziya kwakadzika kupfuura 120K, saka inonzi cryogenic air separation.
Chechipiri ndechekushandisa pressure swing adsorption kugadzira nitrogen
Pressure swing adsorption nzira ndeyekusarudza adsorb oksijeni uye nitrogen zvikamu mumhepo kuburikidza ne adsorbent, uye kuparadzanisa mweya kuti uwane nitrogen.Kana mhepo ikamanikidzwa uye ichipfuura nepakati peiyo adsorption layer yeiyo adsorption shongwe, mamorekuru eokisijeni anonyanya kushambadzwa, uye mamorekuru enitrogen anoramba ari muchikamu chegasi kuti ave nitrogen.Kana iyo adsorption inosvika pakuenzana, mamorekuru eokisijeni adsorbed pamusoro peiyo molecular sieve anobviswa ne decompression kudzoreredza adsorption kugona kweiyo molecular sieve, ndiko kuti, adsorbent analysis.Kuti irambe ichipa nitrogen, iyo unit inowanzo shongedzerwa maviri kana anopfuura adsorption shongwe, imwe yeadsorption uye imwe yekuongorora, uye inochinjirwa kushandiswa panguva yakakodzera.
Nzira yechitatu ndeyekugadzira nitrogen nekuparadzanisa membrane
Membrane separation method ndeyekuparadzanisa nitrogen yakawanda gasi kubva kune yakasanganiswa gasi nekushandisa permeability selectivity yeorganic polymerization membrane.Iyo yakakodzera firimu zvinhu zvinofanirwa kuve nepamusoro kusarudza uye yakakwirira permeability.Kuti uwane maitiro ehupfumi, yakaonda kwazvo polymer yekuparadzanisa membrane inodiwa, saka inoda rutsigiro.Mapurojekiti ekuboora zvombo anowanzo sandara nhumbi dzokurwa dzinobaya projectiles uye hollow fiber armor kubaya projectiles.Munzira iyi, kana kugadzirwa kwegasi kwakakura, nzvimbo yefirimu inodiwa yakakura uye mutengo wefirimu wakakwira.Membrane yekuparadzanisa nzira ine chishandiso chakareruka uye chiri nyore kushanda, asi haina kunyanya kushandiswa muindasitiri.
Kupfupisa, zviri pamusoro ndiyo huru yemukati menzira dzinoverengeka dzekugadzira nitrogen.Kuparadzaniswa kwemhepo yeCryogenic kunogona kuburitsa kwete nitrogen chete, asiwo mvura nitrogen, iyo inogona kuchengetwa mumvura nitrogen yekuchengetedza tank.Kutenderera kwekushanda kwe cryogenic nitrogen kugadzirwa kunowanzo kupfuura gore rimwe, saka michina yekumira haiwanzo kutariswa kugadzirwa kwe nitrogen.Nheyo yekugadzirwa kwenitrogen ne membrane air separation ndeyekuti mweya unopinda mupolymer membrane sefa mushure mekusefa necompressor.Nekuda kwekusiyana kwekunyungudika uye diffusion coefficient yemagasi akasiyana mu membrane, chiyero chepermeation mune akasiyana gasi membranes akasiyana.Kana kuchena kwenitrogen kwakakura kupfuura 98%, mutengo unodarika 15% wakakwira kupfuura wePSA nitrogen jenareta yezvakatsanangurwa zvakafanana.
