300NM3/, 99.99 ubumsulwa nitrogen generator

I-nitrogen, njengeyona gesi ininzi emoyeni, ayipheli kwaye ayipheli. Ayinambala, ayinavumba, iyabonakala, ingaphantsi kwaye ayibuxhasi ubomi. Initrogen ecocekileyo isoloko isetyenziswa njengegesi ekhuselayo kwiindawo apho ioksijini okanye umoya wedwa. Umxholo we-nitrogen (N2) emoyeni ngu-78.084% (iqela lomthamo weegesi ezahlukeneyo emoyeni lihlulwe libe yi-N2: 78.084%, O2: 20.9476%, Argon: 0.9364%, CO2: Enye i-H2, CH4, N2O, I-O3, i-SO2, i-NO2, njl., kodwa umxholo uncinci kakhulu), ubunzima be-molecular yi-28, i-boiling point: -195.8, i-condensation point: -210.

I-Pressure swing adsorption (PSA) inkqubo yokuvelisa initrogen yi-pressure adsorption, i-atmospheric desorption, kufuneka isebenzise umoya ocinezelweyo. Olona xinzelelo lwe-adsorption lwe-carbon molecular sieve esetyenziswayo ngoku yi-0.75 ~ 0.9MPa. Irhasi kuyo yonke inkqubo yokuvelisa initrogen iphantsi koxinzelelo kwaye inefuthe lamandla. Eyesibini, umgaqo wokuvelisa i-nitrogen ye-PSA: i-JY/CMS yokutshintsha uxinzelelo lwe-adsorption umatshini we-nitrogen yi-carbon molecular sieve njenge-adsorbent, usebenzisa i-adsorption yoxinzelelo, umgaqo we-step-down desorption ukusuka kwi-adsorption air kunye nokukhululwa kwe-oksijini, ukuze ukwahlula izixhobo ezizenzekelayo ze-nitrogen. I-Carbon molecular sieve luhlobo lwamalahle njengeyona nto iphambili ekrwada, emva kokugaya, i-oxidation, ukubumba, i-carbonization kunye nokucutshungulwa ngetekhnoloji ekhethekileyo yokucubungula i-groove, umphezulu kunye ne-cylindrical granular adsorbent yangaphakathi egcwele iipores, kwi-inki emnyama, ukuhanjiswa kwegroove njengoko kuboniswe kumzobo ongezantsi: i-carbon molecular sieve ye-pore yesayizi yokusabalalisa iimpawu ze-O2, N2, ngoko inokuqonda ukwahlula okuguquguqukayo. Oku kuhanjiswa kobungakanani bepore kuvumela iigesi ezahlukeneyo ukuba zisasazeke kwiipores ze-molecular sieve ngemilinganiselo eyahlukeneyo ngaphandle kokugxotha nayiphi na igesi kumxube (umoya). Umphumo we-carbon molecular sieve ekuhlukaneni kwe-O2 kunye ne-N2 isekelwe kumahluko omncinci kwi-kinetic diameter yeegesi ezimbini. I-O2 inobubanzi obuncinci bekinetic, ngoko ke inesantya esikhawulezayo sokusasazwa kwi-micropores ye-carbon molecular sieve, ngelixa i-N2 inobubanzi obukhulu bekinetic, ngoko ke isantya sokusasazwa siyacotha. Ukusasazwa kwamanzi kunye ne-CO2 emoyeni ocinezelweyo kufana ne-oxygen, ngelixa i-argon isasazeka ngokukhawuleza. Ugxininiso lokugqibela oluvela kwikholamu ye-adsorption ngumxube we-N2 kunye ne-Ar. Iimpawu ze-adsorption ze-carbon molecular sieve ye-O2 kunye ne-N2 inokubonakaliswa ngokubonakalayo nge-equilibrium adsorption curve kunye ne-dynamic adsorption curve: ukusuka kwezi zimbini ze-adsorption curves, kunokubonwa ukuba ukwanda koxinzelelo lwe-adsorption kunokwenza umthamo we-adsorption we-O2 kunye ne-N2 yanda. ngexesha elifanayo, kunye nokunyuka kwe-adsorption ye-O2 umthamo omkhulu. Ixesha le-adsorption swing yoxinzelelo lifutshane, kwaye umthamo we-adsorption we-O2 kunye ne-N2 ukude nokufikelela kwi-equilib (ixabiso eliphezulu), ngoko ke umahluko wezinga lokusasazwa kwe-O2 kunye ne-N2 yenza umthamo we-adsorption we-O2 ugqithise kakhulu kwi-N2 ngokufutshane. ixesha lexesha. Uxinzelelo lwe-adsorption ye-nitrogen imveliso kukusetyenziswa kwe-carbon molecular sieve ekhethiweyo iimpawu ze-adsorption, ukusetyenziswa kwe-adsorption yoxinzelelo, umjikelo we-decompression desorption, ukuze umoya ucinezele ngokutshintshana kwi-adsorption tower (enokugqitywa yinqaba enye) ukufezekisa ukwahlukana komoya, ukuze ngokuqhubekayo ukuvelisa i-nitrogen yemveliso ecocekileyo.
