300NM3/, 99.99 chiyero nayitrogeni jenereta

Nayitrojeni, monga mpweya wochuluka kwambiri mumpweya, ndi wosatha komanso wosatha. Ndiwopanda mtundu, wopanda fungo, wowonekera, wocheperako ndipo suthandizira moyo. Nayitrogeni yoyera kwambiri imagwiritsidwa ntchito ngati gasi woteteza m'malo omwe mpweya kapena mpweya umakhala pawokha. Zomwe zili mu nayitrogeni (N2) mumlengalenga ndi 78.084% (gulu lamitundu yosiyanasiyana ya mpweya mumlengalenga limagawidwa kukhala N2: 78.084%, O2: 20.9476%, Argon: 0.9364%, CO2: Zina H2, CH4, N2O, O3, SO2, NO2, etc., koma zili zochepa kwambiri), kulemera kwa maselo ndi 28, mfundo yowira: -195.8, condensation point: -210.

Pressure swing adsorption (PSA) kupanga nayitrogeni kupanga ndi kuthamanga adsorption, mumlengalenga desorption, ayenera kugwiritsa ntchito wothinikizidwa mpweya. Kuthamanga kwabwino kwa adsorption ya carbon molecular sieve yomwe imagwiritsidwa ntchito pano ndi 0.75 ~ 0.9MPa. Mpweya wamtundu wonse wa nayitrogeni umapanikizika ndipo umakhudza mphamvu. Awiri, PSA nayitrogeni kupanga mfundo: JY/CMS kuthamanga kusintha adsorption nayitrogeni makina ndi mpweya maselo sieve monga adsorbent, ntchito kuthamanga adsorption, sitepe-pansi desorption mfundo ku mpweya adsorption ndi kumasulidwa kwa mpweya, kuti apatule zida basi nayitrogeni. Mpweya wamagetsi sieve ndi mtundu wa malasha monga zopangira zazikulu, pambuyo popera, makutidwe ndi okosijeni, akamaumba, carbonization ndi kukonzedwa kudzera mwapadera poyambira processing luso, pamwamba ndi mkati cylindrical granular adsorbent kuti wodzaza pores, mu inki wakuda, kugawa poyambira monga zomwe zikuwonetsedwa m'chithunzichi: mpweya wa carbon molecular sieve pore kukula kwa mawonekedwe a O2, N2, kuti athe kuzindikira kulekanitsa kwakukulu. Kugawa kwa kukula kwa pore kumeneku kumapangitsa kuti mpweya wosiyanasiyana ulowe mu pores za sieve ya maselo mosiyanasiyana popanda kuthamangitsa mpweya uliwonse wosakanikirana (mpweya). Zotsatira za sieve ya carbon molecular pa kupatukana kwa O2 ndi N2 zimachokera ku kusiyana kochepa kwa kinetic awiri a mipweya iwiriyi. O2 ili ndi mainchesi ang'onoang'ono a kinetic, motero imakhala ndi kufalikira kwachangu mu ma micropores a carbon molecular sieve, pomwe N2 ili ndi mainchesi akulu akulu, kotero kufalikira kumachepa. Kufalikira kwa madzi ndi CO2 mu mpweya wopanikizidwa ndi ofanana ndi mpweya, pamene argon imafalikira pang'onopang'ono. Kuphatikizika komaliza kuchokera pagawo la adsorption ndi chisakanizo cha N2 ndi Ar. Makhalidwe adsorption a carbon molecular sieve ya O2 ndi N2 akhoza kuwonetsedwa mwachidwi ndi mayendedwe adsorption adsorption curve ndi mphamvu ya adsorption curve: kuchokera ku ma curve awiriwa, zikhoza kuwoneka kuti kuwonjezeka kwa kuthamanga kwa adsorption kungapangitse mphamvu ya odsorption ya O2 ndi N2 kuwonjezeka. nthawi yomweyo, ndipo kuwonjezeka kwa O2 adsorption mphamvu ndi yaikulu. Kuthamanga kugwedezeka kwa nthawi yayitali ndi yochepa, ndipo mphamvu ya O2 ndi N2 ili kutali kuti ifike pamtunda (mtengo wapatali), kotero kusiyana kwa kufalikira kwa O2 ndi N2 kumapangitsa kuti mphamvu ya O2 ikhale yopambana kwambiri ya N2 mwachidule. nthawi. Pressure swing adsorption nayitrogeni kupanga ndikugwiritsa ntchito mawonekedwe a carbon molecular sieve kusankha adsorption, kugwiritsa ntchito kuthamanga kwa adsorption, decompression desorption cycle, kotero kuti wothinikizidwa mpweya mosinthana mu nsanja ya adsorption (ingathenso kumalizidwa ndi nsanja imodzi) kuti akwaniritse kulekana kwa mpweya, kuti mosalekeza kubala mkulu chiyero mankhwala asafe.
