Nigute Uruganda rwa Oxygene rwa VPSA rukora?

VPSA, cyangwa Vacuum Pressure Swing Adsorption, ni ikoranabuhanga rishya rikoreshwa mugukora ogisijeni nziza cyane. Ubu buryo bukubiyemo gukoresha icyuma cyihariye cya molekile yihariye ihitamo imyanda nka azote, dioxyde de carbone, n’amazi ava mu kirere ku gitutu cy’ikirere. Icyo cyuma noneho kijugunywa mu bihe bya vacuum, kurekura iyo myanda no gutanga ogisijeni ifite ubuziranenge bwa 90-93%. Iyi nzira yikurikiranya irakora neza kandi yangiza ibidukikije, bigatuma ihitamo neza inganda zisaba ubwinshi bwa ogisijeni nziza.

UwitekaVPSA igihingwa cya ogisijeniikora binyuze murukurikirane rwibigize ubuhanga, harimo blower, pompe vacuum, valve ihindura, umunara wa adsorption, hamwe na tank ya ogisijeni. Inzira itangirana no gufata umwuka mubi, uyungurura kugirango ukureho umukungugu. Uyu mwuka wayungurujwe uhita ushyirwaho igitutu na Roots kumuvuduko wa 0.3-0.5 BARG hanyuma ikoherezwa murimwe muminara ya adsorption. Imbere yumunara, umwuka uhura nibikoresho bya adsorbent. Munsi yumunara, alumina ikora adsorbs amazi, dioxyde de carbone, nizindi myuka ya gaze. Hejuru yiki gipimo, molekile ya zeolite ikuramo adsorb azote, ituma ogisijeni na argon byanyura nka gaze yibicuruzwa. Iyi gaze ikungahaye kuri ogisijeni noneho ikusanyirizwa mu kigega cya ogisijeni.

Mugihe gahunda ya adsorption ikomeje, ibikoresho bya adsorbent bigenda byuzura buhoro buhoro. Kuri iyi ngingo, sisitemu ihindura icyiciro gishya. Umuyoboro uhinduranya uyobora imigendekere itandukanye, kandi pompe vacuum igabanya umuvuduko muminara kuri 0.65-0.75 BARG. Iyi vacuum irekura imyanda yamamajwe, hanyuma igasohoka mukirere, igahindura neza adsorbent kumurongo ukurikira.

UwitekaAmashanyarazi ya VPSAyagenewe gukora ubudahwema, itanga isoko ihamye ya ogisijeni yuzuye. Imikorere yacyo no kwizerwa bituma iba ikintu cyingenzi mubikorwa bitandukanye, harimo ubuvuzi, inganda, na metallurgie. Ubushobozi bwo gukora ogisijeni kurubuga bugabanya ibibazo bya logistique hamwe nigiciro kijyanye nuburyo gakondo bwo gutanga ogisijeni, nko gutanga gaze ya gaze cyangwa compression.

Byongeye kandi, tekinoroji ya VPSA ni nini, itanga ihinduka kugirango ihuze urwego rutandukanye rwa ogisijeni. Ihinduka, rifatanije ninyungu zibidukikije hamwe nigiciro-cyiza, imyanya VPSAO₂uruganda rutunganya umusaruronkigisubizo kiyobora kubyara ogisijeni mubijyanye ninganda zigezweho. Mu gihe inganda zikomeje gushakisha uburyo burambye kandi bunoze bwo kubyaza umusaruro, uruganda rwa ogisijeni rwa VPSA rugaragara nk’ikoranabuhanga ritekereza imbere ryujuje ibi bipimo mu gihe rutanga itangwa rya ogisijeni yo mu rwego rwo hejuru.
