Umwirondoro w'isosiyete
Amazi ya azote yatunganijwe nishami ryacu afata Pressure Swing Adsorption (PSA) kugirango ategure azote nziza, hanyuma igaterwa na gaze ivanze na gaz joule-thomson Refrigeration Cycle, MRC mugihe gito) kugirango itange azote ikenewe.
Amahame yo gukora
Urebye kuri firigo yerekanwe ku gishushanyo cya 1, imikorere yayo ni: firigo yumuvuduko ukabije wa firigo ku bushyuhe bw’ibidukikije T0 (ihuye n’ingingo ya 1s) ihagarikwa muri gaze y’umuvuduko ukabije w’ubushyuhe bwo hejuru (ingingo ya 2) na compressor, na hanyuma yinjira muri cooler, nibindi bikonje bikonje ubushyuhe bwibidukikije (point 3), byinjira mubyahinduwe nubushyuhe bushya, bikomeza gukonjeshwa na gazi ya gazi yo hasi yubushyuhe bwo hasi kugeza kuri point ya 4, yinjira muri valve ya trottle, adiabatic itera kuri point 5, ubushyuhe buragabanuka, kandi bwinjira mumashanyarazi kugirango butange ubukonje Iyo ubushyuhe buzamutse bugera ku ngingo ya 6, bwinjira mu muvuduko ukabije w’umuvuduko ukabije w’ubushyuhe, kandi mugihe ukonje umuvuduko ukabije w’umuvuduko winjira, ubushyuhe bwacyo buhoro buhoro busubira ku ngingo 1, hanyuma yinjira mumuyoboro uhuza ubushyuhe hamwe na compressor. Hashobora kuba igice cya sisitemu muri iki gihe Ubushyuhe butemba, ubushyuhe burazamuka kugera ku bushyuhe bw’ibidukikije, bugaruka kuri leta kumwanya wa 1 isegonda, kandi sisitemu ikarangiza ukwezi. Sisitemu yo gukonjesha igabanya buhoro buhoro ubushyuhe ukurikije inzira yavuzwe haruguru, kandi amaherezo itanga ubushobozi bwo gukonjesha ku bushyuhe bwa firigo Tc. Mugukwirakwiza ubushyuhe bwo gukonjesha, ubushobozi bwo gukonjesha butangwa buhoro buhoro mugihe cyo kugaruka, nka gaze ya gaze naturel, nibindi.
Ibiranga firigo ivanze ya firigo
1) Gutangira vuba no gukonjesha vuba. Binyuze mu kigereranyo cya firigo ivanze, compressor ubushobozi bwo guhinduranya hamwe na trottle valve ifungura kugenzura, ibisabwa gukonjesha byihuse birashobora kugerwaho;
2) Inzira iroroshye, umubare wibikoresho ni muto, kandi sisitemu yo kwizerwa ni myinshi. Ibice byingenzi bigize sisitemu bifata compressor ikuze, ihinduranya ubushyuhe nibindi bikoresho murwego rwa firigo. Sisitemu ifite ubwizerwe buhanitse hamwe nibikoresho byinshi bituruka.
Igiciro cyiterambere cyibikoresho bivangwa na firigo ya azote igizwe ahanini nibice bibiri: amashanyarazi ya azote ya PSA hamwe nigice cya MRC. Amashanyarazi ya azote ya PSA arakuze kandi biroroshye kugura ku isoko ryimbere mu gihugu.
