300NM3 /, 99.99 ubumsulwa i-nitrogen generator

I-nitrogen, njengegesi eningi kakhulu emoyeni, ayipheli futhi ayipheli. Ayinambala, ayinaphunga, isobala, i-subinert futhi ayisekeli impilo. Ukuhlanzeka okuphezulu kwe-nitrogen kuvame ukusetshenziswa njengegesi evikelayo ezindaweni lapho umoya-mpilo noma umoya uhlukanisiwe. Okuqukethwe kwe-nitrogen (N2) emoyeni ngama-78.084% (iqembu levolumu lamagesi ahlukahlukene emoyeni lihlukaniswe laba yi-N2: 78.084%, O2: 20.9476%, Argon: 0.9364%, CO2: Other H2, CH4, N2O, O3, SO2, NO2, njll., Kodwa okuqukethwe kuncane kakhulu), isisindo samangqamuzana singama-28, iphuzu lokubilisa: -195.8, iphoyinti lokunciphisa: -210.

Inqubo yokukhiqiza ingcindezi ye-Pressure swing adsorption (PSA) ingcindezi yokukhishwa kwamakhemikhali, ukukhishwa kwomoya emkhathini, kufanele kusebenze umoya ocindezelweyo. Ingcindezi engcono kakhulu yokukhangisa nge-sieve yamangqamuzana esetshenziswa manje i-0.75 ~ 0.9MPa. Igesi kulo lonke uhlelo lokukhiqiza i-nitrogen ingaphansi kwengcindezi futhi inamandla omthelela. Okwesibili, isimiso sokukhiqizwa kwe-PSA nitrogen: Umshini we-JY / CMS ushintsho lwe-adsorption nitrogen umshini uyisihlakala se-carbon yamangqamuzana njenge-adsorbent, usebenzisa ingcindezi adsorption, i-step-down desorption simiso kusuka ku-adsorption yomoya nokukhululwa komoya-mpilo, ukuze uhlukanise imishini ezenzakalelayo ye-nitrogen. Carbon ngesihlungo yamangqamuzana uhlobo amalahle njengoba impahla main eluhlaza, emva ukugaya, namachibi, udini, carbonization futhi kusetshenzwe ngokusebenzisa ekhethekile inkatho ukucutshungulwa ubuchwepheshe, ebusweni futhi yangaphakathi cylindrical luyimbudumbudu adsorbent ukuthi ugcwele pores, ngo-inki omnyama, ukusatshalaliswa inkatho njengoba kuboniswe kumfanekiso ongezansi: izici ze-carbon molecular sieve pore size distribution of O2, N2, ngakho-ke ingabona ukwehlukana okunamandla. Lokhu kusatshalaliswa kosayizi wepore kuvumela amagesi ahlukene ukuthi angene ezimbotsheni zesihlungo samangqamuzana ngamazinga ahlukile ngaphandle kokuxosha noma yimaphi amagesi akulo mxube (umoya). Umphumela wesisefo sekhabhoni yamangqamuzana ekwehlukanisweni kwe-O2 ne-N2 kusekelwe kumehluko omncane kububanzi be-kinetic wamagesi amabili. I-O2 inobubanzi obuncane be-kinetic, ngakho-ke inezinga lokusabalalisa okusheshayo kuma-micropores we-carbon molecular sieve, kuyilapho i-N2 inobubanzi obukhulu be-kinetic, ngakho-ke izinga lokusabalalisa lihamba kancane. Ukusabalalisa kwamanzi ne-CO2 emoyeni ocindezelweyo kufana nokwe-oxygen, kuyilapho i-argon isakazeka kancane. Ukuhlushwa kokugcina okuvela kukholamu yokukhangisa kuyingxube ye-N2 ne-Ar. Izici zokukhangisa ze-carbon sieve yamangqamuzana e-O2 ne-N2 zingakhonjiswa intuitively ngejika lokulinganisa le-adsorption kanye nejika elinamandla le-adsorption: kusuka kulawa majika amabili we-adsorption, kungabonakala ukuthi ukwanda kwengcindezi ye-adsorption kungenza amandla we-adsorption we-O2 no-N2 ande ngasikhathi sinye, futhi ukwanda komthamo we-adsorption we-O2 kukhulu. Isikhathi sokukhishwa kwengcindezi ye-swing sifushane, futhi amandla we-adsorption we-O2 ne-N2 akanakude nokufinyelela (inani eliphakeme kakhulu), ngakho-ke umehluko wesilinganiso sokusakazwa kwe-O2 ne-N2 wenza umthamo we-adsorption we-O2 weqe kakhulu lowo we-N2 ngamafuphi isikhathi. Ingcindezi jika adsorption ukukhiqizwa kwe-nitrogen ukusetshenziswa kwe-carbon molecular sieve izici ze-adsorption ezikhethiwe, ukusetshenziswa kwengcindezi adsorption, decompression desorption cycle, ukuze umoya ocindezelweyo ungene endaweni yombhoshongo we-adsorption (ungaphothulwa ngumbhoshongo owodwa) ukufeza ukwahlukana komoya, ukuze ukhiqize ngokuqhubekayo ubumsulwa obuphezulu be-nitrogen yomkhiqizo.
