Cryogenic mhando yakakwira yakakwira kuchena nitrogen mhepo yekuparadzanisa chirimwa mvura uye okisijeni jenareta
Product Advantages
1.Kuisa nyore uye kugadzirisa kuvonga kune modular dhizaini uye kuvaka.
2.Fully automated system yekushanda nyore uye yakavimbika.
3.Guaranteed kuwanikwa kwepamusoro-kuchena kwemagasi emaindasitiri.
4.Kuvimbiswa nekuwanikwa kwechigadzirwa muchikamu chemvura kuti chichengetwe kuti chishandiswe panguva ipi neipi yekugadzirisa mabasa.
5.Kuderedza simba rekushandisa.
6.Kutora nguva pfupi.
Minda Yekushandisa
Oxygen, nitrogen, argon uye imwe gasi isingawanzogadzirwa nemhepo yekuparadzanisa unit inoshandiswa zvakanyanya musimbi, kemikari.
indasitiri, kunatsa, girazi, rabha, zvemagetsi, hutano, chikafu, simbi, kugadzira magetsi uye mamwe maindasitiri.

Process flow
Mhepo yakapfava inobva kumhepo, inoenda nepamhepo sefa yekubvisa huruva uye imwe mechanicha particle uye inopinda isina-lub air compressor kuti inyinywe nematanho maviri compressor kusvika approx. 0.65MPa(g) .Inopinda nemuinotonhorera uye inopinda precooling unit kuti itonhodzwe kusvika 5~10℃. Inobva yaenda kushandura-pamusoro MS purifier yekubvisa hunyoro, CO2, kabhoni hydrogen. Purifier ine maviri molecular sieve izere midziyo. Imwe iri kushandiswa apo anther iri pasi pekuvandudzwa nemarara nitrogen kubva mubhokisi rinotonhora uye kuburikidza nekudziya kwehita.
Mushure mekucheneswa, chikamu chidiki chayo chinoshandiswa sekutakura gasi returbine expander, imwe inopinda mubhokisi rinotonhora kuti itonhodzwe nereflux (oxygen yakachena, pure nitrogen uye tsvina nitrogen) mune main heat exchanger. Chikamu chemhepo chinobviswa kubva pakati pechikamu chikuru chekupisa kupisa uye chinoenda kune yekuwedzera turbine yekugadzira kutonhora. Mhepo yakawanda yakawedzerwa inoenda kuburikidza ne subcooler iyo inotonhodzwa neokisijeni kubva kumusoro kwekoramu kuti iunzwe kune yepamusoro column. Chikamu chidiki chayo chinodarika nekubypass kunorasa nitrogen pombi zvakananga uye inodziyiswa kuti ibude mubhokisi rinotonhora. Chimwe chikamu chemhepo chinoramba chichitonhodzwa kusvika pedyo nemhepo yemvura inoedza kudzikisa column.
Mumhepo yakadzika mhepo, mhepo inoparadzaniswa uye inonyungudutswa semvura nitrogen uye mhepo yemvura. Chikamu chemvura nitrogen s inotorwa kubva pamusoro peiyo mbiru yepasi. Mhepo yemvura yakadzika mushure mekunyungudika uye throttled inounzwa kune yepakati chikamu chepamusoro mbiru se reflux.
Chigadzirwa okisijeni inobviswa kubva pazasi chikamu chepamusoro mbiru uye inopiswazve nemhepo yakawedzera subcooler, main heat exchange. Zvadaro inobudiswa kunze kwekoramu. Waste nitrogen inotorwa kubva kumusoro kwembiru uye inodziyiswa musubcooler uye main heat exchanger kuti ibude mukoramu. Chikamu chacho chinoshandiswa segasi rekuvandudza kweMS purifier. Naitrojeni yakachena inotorwa kubva pamusoro pembiru yekumusoro uye inopiswazve mumhepo ine mvura, mvura ine nitrogen subcooler uye main heat exchanger kuti iunzwe kunze kwekoramu.
Oxygen kunze kweiyo distillation column inomanikidzwa kune mutengi.
