I-300NM3 /, 99.99 yokucoceka kwenitrogen

I-nitrojeni, njengeyona gesi ininzi esemoyeni, ayinakutshiswa kwaye ayipheli. Ayinambala, ayinasiphelo, iyabonakala, i-subinert kwaye ayixhasi bomi. Ukucoceka okuphezulu kwe-nitrogen kuhlala kusetyenziswa njengegesi yokukhusela kwiindawo apho ioksijini okanye umoya ubekelwe bucala. Umxholo we-nitrogen (N2) emoyeni ngama-78.084% (iqela levolthi ezahlukeneyo lizahlula 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 mncinci kakhulu), ubunzima beemolekyuli ngama-28, indawo yokubilisa: -195.8, inqaku lokunyanzelwa: -210.

Uxinzelelo lwe-swing adsorption (PSA) inkqubo yemveliso ye-nitrojini kukucinezelwa kwe-adsorption, ukususwa komoya esesibhakabhakeni, kufuneka usebenzise umoya ocinezelweyo. Olona xinzelelo lubalaseleyo lwe-adsorption lwekhabhoni yemolekyuli yokusefa esetyenzisiweyo ngoku yi-0.75 ~ 0.9MPa. Irhasi kuyo yonke inkqubo yemveliso ye-nitrogen iphantsi koxinzelelo kwaye inefuthe lamandla. Okwesibini, umgaqo wemveliso ye-nitrojeni ye-PSA: Utshintsho lwe-JY / CMS lotshintsho lwe-adsorption umatshini we-nitrogen yi-carbon molecular sieve njenge-adsorbent, usebenzisa uxinzelelo lwe-adsorption, inyathelo lokuyeka ukususwa kwi-adsorption yomoya kunye nokukhululwa kweoksijini, ukwahlula izixhobo ezizenzekelayo zenitrojeni. Ikharbon yokusefa yemolekyuli luhlobo lwamalahle njengezona zinto ziphambili ziphambili, emva kokuguba, ioksijini, ukubumba, ukulungiswa kwekhabhoni kunye nokusetyenzwa kwitekhnoloji yokulungisa i-groove ekhethekileyo, umphezulu kunye nangaphakathi we-cylindrical granular adsorbent ogcwele pores, nge-inki emnyama, ukuhanjiswa kwe-groove njenge kubonisiwe kumzobo ongezantsi: iikhabhoni zemolekyuli yokuluka ubungakanani bepore ukuhanjiswa kweempawu ze-O2, N2, ukuze ikwazi ukuqonda ukwahlula okunamandla. Olu nikezelo lobungakanani bepore luvumela iigesi ezahlukeneyo ukuba zisasazeke kwimingxunya yesisele seemolekyuli kumaxabiso ahlukeneyo ngaphandle kokugxotha nayiphi na igesi kumxube (umoya). Iziphumo zesefu yekhabhoni yemolekyuli ekwahlukaneni kwe-O2 kunye ne-N2 isekwe kumahluko omncinci kububanzi be-kinetic yeegesi ezimbini. I-O2 inobubanzi obuncinci be-kinetic, ke inezinga lokusasazeka okukhawulezileyo kwii-micropores ze-carbon molecular sieve, ngelixa i-N2 inobubanzi be-kinetic ubukhulu, ke inqanaba lokusasazeka lihamba kancinci. Ukusasazeka kwamanzi kunye ne-CO2 emoyeni oxineneyo kuyafana neoksijini, ngelixa iargon isasazeka kancinci. Ukugqitywa kokugqibela kwikholamu ye-adsorption ngumxube we-N2 kunye no-Ar. Iimpawu ze-adsorption ze-carbon molecular sieve ye-O2 kunye ne-N2 inokubonakaliswa ngokungenantlonelo ngumlinganiso we-adsorption curve kunye ne-adsorption curve eguqukayo: kwezi zimbini zivelisi zokujonga, kuyabonakala ukuba ukonyuka koxinzelelo lwe-adsorption kunokwenza ukuba umthamo we-adsorption we-O2 kunye no-N2 unyuke Kwangelo xesha, kwaye ukonyuka kwamandla e-adsorption ye-O2 inkulu. Uxinzelelo lwe-swing adsorption xesha lifutshane, kwaye umthamo we-adsorption we-O2 kunye ne-N2 ukude ekufikeleleni kumlinganiso (elona xabiso liphezulu), ke umahluko wenqanaba lokusasazeka kwe-O2 kunye ne-N2 yenza ukuba umthamo we-adsorption we-O2 ugqithe kakhulu kunowama-N2 ngokufutshane ixesha. Uxinzelelo lwe-swing adsorption kwimveliso ye-nitrogen kukusetyenziswa kweempawu ze-adsorption ezikhethiweyo zecarbon, ukusetyenziswa kwe-adsorption yoxinzelelo, umjikelo we-decompression desorption, ukuze umoya ucinezelwe ngokuthe ngqo kwi-adsorption tower (inokugqitywa ngenqaba enye) ukufezekisa ukwahlukana komoya, Ukuqhubeka nokuvelisa imveliso ye-nitrogen esulungekileyo.
