300NM3/, 99.99 jeneretha ye-nitrogen ehlanzekile

I-nitrogen, njengegesi eningi kakhulu emoyeni, ayipheli futhi ayipheli. Ayinambala, ayinaphunga, isobala, ayisekeli ukuphila. I-nitrogen ehlanzekile ivame ukusetshenziswa njengegesi evikelayo ezindaweni lapho umoya-mpilo noma umoya uhlukanisiwe. Okuqukethwe kwe-nitrogen (N2) emoyeni yi-78.084% (iqembu levolumu lamagesi ahlukahlukene emoyeni lihlukaniswe laba yi-N2: 78.084%, O2: 20.9476%, i-Argon: 0.9364%, CO2: Okunye H2, CH4, N2O, O3, SO2, NO2, njll., kodwa okuqukethwe kuncane kakhulu), isisindo samangqamuzana angama-28, iphuzu elibilayo: -195.8, iphuzu lokufingqa: -210.

Inqubo yokukhiqiza i-Pressure swing adsorption (PSA) i-nitrogen adsorption, i-atmospheric desorption, kufanele isebenzise umoya ocindezelweyo. Ingcindezi ye-adsorption engcono kakhulu yesisefo se-carbon molecular esetshenziswa manje ngu-0.75~0.9MPa. Igesi kulo lonke uhlelo lokukhiqiza i-nitrogen ingaphansi kwengcindezi futhi inomthelela wamandla. Okwesibili, isimiso sokukhiqiza i-nitrogen ye-PSA: Umshini we-JY/CMS wokushintsha ingcindezi ye-adsorption nitrogen isisefo se-carbon molecular njenge-adsorbent, usebenzisa i-pressure adsorption, isimiso sokudonsela phansi esisuka phansi ekukhangiseni komoya kanye nokukhululwa komoya-mpilo, ukuze kuhlukaniswe izisetshenziswa ezizenzakalelayo ze-nitrogen. I-Carbon molecular sieve iwuhlobo lwamalahle njengento eluhlaza eyinhloko, ngemva kokugaya, i-oxidation, ukubumba, i-carbonization futhi icutshungulwe ngobuchwepheshe obukhethekile bokucubungula i-groove, i-adsorbent yangaphakathi ye-cylindrical granular egcwele ama-pores, ngoyinki omnyama, ukusatshalaliswa kwe-groove njenge kuboniswe emfanekisweni ongezansi: izici zokusabalalisa usayizi wembotshana ye-carbon molecular sieve ye-O2, N2, ukuze ikwazi ukubona ukuhlukana okunamandla. Lokhu kusatshalaliswa kosayizi wembobo kuvumela amagesi ahlukene ukuthi asakazekele ezimbotsheni zesisefo samangqamuzana ngamanani ahlukene ngaphandle kokuxosha noma yimaphi amagesi kungxube (umoya). Umphumela we-carbon molecular sieve ekuhlukaniseni i-O2 ne-N2 usekelwe emehlukweni omncane kububanzi be-kinetic bamagesi amabili. I-O2 inobubanzi obuncane be-kinetic, ngakho-ke inenani lokusabalalisa ngokushesha kuma-micropores we-carbon molecular sieve, kuyilapho i-N2 inobubanzi obukhulu be-kinetic, ngakho izinga lokusabalalisa lihamba kancane. Ukusatshalaliswa kwamanzi kanye ne-CO2 emoyeni ocindezelwe kufana nalokho komoya-mpilo, kuyilapho i-argon isakazeka kancane. Ukugxila kokugcina okuvela kukholomu ye-adsorption kuyingxube ye-N2 ne-Ar. Izici ze-adsorption ze-carbon molecular sieve ye-O2 ne-N2 zingaboniswa ngokunembile ngejika le-adsorption elilinganayo kanye nejika le-adsorption eliguqukayo: kusuka kulawa majika amabili e-adsorption, kungabonakala ukuthi ukwanda kwengcindezi ye-adsorption kungenza amandla okukhangisa e-O2 kanye ne-N2 akhuphuke. ngesikhathi esifanayo, futhi ukwanda komthamo we-O2 adsorption kukhulu. Isikhathi sokukhangisa ngokushwibeka kwengcindezi sifushane, futhi amandla okukhangisa e-O2 ne-N2 asekude nokufinyelela ukulingana (inani eliphakeme), ngakho-ke umehluko wezinga lokusabalalisa le-O2 ne-N2 lenza umthamo we-adsorption we-O2 udlule kakhulu owe-N2 ngamafuphi. isikhathi. Ukukhiqizwa kwe-nitrogen ye-pressure swing ukusetshenziswa kwe-carbon molecular sieve selective adsorption izici, ukusetshenziswa kwe-pressure adsorption, decompression desorption cycle, ukuze umoya ocindezelwe ngokushintshana ungene kumbhoshongo we-adsorption (ungabuye uqedelwe ngombhoshongo owodwa) ukuze kuzuzwe ukuhlukaniswa komoya, ukuze ukhiqize ngokuqhubekayo umkhiqizo ohlanzekile we-nitrogen.
