300NM3 /, 99.99 yoyera nayitrogeni jenereta

Nayitrogeni, monga mpweya wochuluka kwambiri mlengalenga, sungathe ndipo sutha. Ndi yopanda mtundu, yopanda fungo, yowonekera, subinert ndipo sichichirikiza moyo. Kuyera kwambiri kwa nayitrogeni nthawi zambiri kumagwiritsidwa ntchito ngati mpweya woteteza m'malo omwe mpweya kapena mpweya umakhala wokha. Zomwe zili mu nayitrogeni (N2) mlengalenga ndi 78.084% (gulu lamagetsi am'mlengalenga agawika N2: 78.084%, O2: 20.9476%, Argon: 0.9364%, CO2: H2 ina, CH4, N2O, O3, SO2, NO2, ndi zina zambiri, koma zomwe zili zochepa kwambiri), kulemera kwake kwama cell ndi 28, malo otentha: -195.8, condensation point: -210.

Anzanu kupeta kumamatira (PSA) nayitrogeni ndondomeko kupanga ndi kuthamanga kumamatira, desorption mumlengalenga, ayenera ntchito wothinikizidwa mpweya. Kuthamanga kwabwino kwambiri kwa mpweya wa mpweya wa carbon womwe wagwiritsidwa ntchito tsopano ndi 0.75 ~ 0.9MPa. Mpweya wonse wopanga nayitrogeni umapanikizika ndipo umakhudza mphamvu. Chachiwiri, PSA yopanga nayitrogeni mfundo: JY / CMS kukakamiza kusintha kotsekemera kwa nayitrogeni makina ndi mpweya wa sieve monga adsorbent, pogwiritsira ntchito kupanikizika, kutsika pansi kotulutsa mpweya ndi kutulutsa mpweya, kuti mugawane zida zokhazokha za nayitrogeni. Mpweya wokhala ndi mpweya ndi mtundu wa malasha ngati chinthu chofunikira kwambiri, mutagaya, makutidwe ndi okosijeni, kuumba, kukhathamiritsa komanso kukonzanso ukadaulo wapakatikati, wamkati ndi wamkati wamkati wonenepa womwe umadzaza ndi ma pores, inki yakuda, kugawa kwa poyambira monga akuwonetsedwa pachithunzipa pansipa: mawonekedwe a kaboni wamasamba pore kukula kwa O2, N2, kuti athe kuzindikira kupatukana kwamphamvu. Kugawidwa kwa pore uku kumalola mpweya wosiyanasiyana kufalikira m'mitsempha ya sieve yamankhwala pamitengo yosiyana osataya mpweya uliwonse wosakanikirana (mpweya). Mphamvu ya sieve ya kaboni yamphamvu pakulekanitsidwa kwa O2 ndi N2 kutengera kusiyana kwakung'ono m'mizere yayikulu yamipweya iwiriyo. O2 imakhala ndi matenthedwe ang'onoang'ono, chifukwa chake imakhala ndi mayendedwe ofulumira kwambiri mu micropores of carbon mole sieve, pomwe N2 ili ndi kukula kwakukulu kwa kinetic, chifukwa chake kufalikira kwake kumachedwa pang'onopang'ono. Kusakanikirana kwa madzi ndi CO2 mu mpweya wopanikizika ndikofanana ndi mpweya, pomwe argon imafalikira pang'onopang'ono. Kutsiriza komaliza kuchokera pagawo lazotsatsa ndi chisakanizo cha N2 ndi Ar. Makhalidwe obwezeretsa mpweya wa kaboni wamtundu wa O2 ndi N2 amatha kuwonetsedwa mwachidwi ndi khola lofananira ndi kapangidwe kake kokhazikika: nthawi yomweyo, ndipo kuwonjezeka kwa mphamvu yotsatsira O2 ndikokulirapo. Kupsinjika kwakanthawi kwakanthawi kochepa ndikufupika, ndipo kutulutsa kwa O2 ndi N2 sikukufikira kufanana (mtengo wokwanira), chifukwa chake kusiyana kwa kufalikira kwa O2 ndi N2 kumapangitsa kutsatsa kwa O2 kupitilira kwa N2 mwachidule nthawi. Anzanu kupeta kumamatira nayitrogeni kupanga ndi ntchito mpweya maselo sieve kusankha makhalidwe kumamatira, ntchito kuthamanga kumamatira, decompression desorption mkombero, kotero kuti wothinikizidwa mpweya alternately mu kumamatira nsanja (akhoza kutha ndi nsanja imodzi) kukwaniritsa kupatukana mpweya, kuti mosalekeza kutulutsa mkulu chiyero mankhwala nayitrogeni.
