Pehea e hana ai ka VPSA Oxygen Plant?

ʻO VPSA, a i ʻole Vacuum Pressure Swing Adsorption, he ʻenehana hou i hoʻohana ʻia i ka hana ʻana o ka oxygen maʻemaʻe kiʻekiʻe. ʻO kēia kaʻina hana i ka hoʻohana ʻana i kahi kānana molekala kūikawā e hoʻopili i nā mea haumia e like me ka nitrogen, carbon dioxide, a me ka wai mai ka lewa ma ke kaomi ʻana i ka lewa. Hoʻopau ʻia ka sieve ma lalo o nā kūlana vacuum, hoʻokuʻu i kēia mau haumia a hana i ka oxygen me kahi pae maʻemaʻe o 90-93%. ʻO kēia kaʻina hana cyclical maikaʻi loa a pili i ke kaiapuni, e lilo ia i mea koho maikaʻi loa no nā ʻoihana e koi ana i ka nui o ka oxygen maʻemaʻe.

ʻO kaVPSA mea kanu oxygene hana ana ma o ka mooolelo o na mea maalea, e like me ka blower, ka pahu hau, ka pahu hoʻololi, ka hale kiaʻi adsorption, a me ka pahu kaulike oxygen. Hoʻomaka ke kaʻina hana me ka lawe ʻana i ka ea maka, kahi i kānana ʻia e wehe i nā ʻāpana lepo. Hoʻopili ʻia kēia ea kānana e kahi mea puhi Roots i kahi kaomi o 0.3-0.5 BARG a kuhikuhi ʻia i kekahi o nā hale kiaʻi adsorption. I loko o ka hale kiaʻi, pili ka ea me nā mea adsorbent. Ma ka lalo o ka hale kiaʻi, hoʻopili ka alumina i ka wai, carbon dioxide, a me nā kinoea ʻē aʻe. Ma luna aʻe o kēia papa, hoʻopili nā kānana molekole zeolite i ka nitrogen, e ʻae ana i ka oxygen a me ka argon e hele ma ke ʻano he kinoea huahana. A laila e hōʻiliʻili ʻia kēia kinoea momona i ka oxygen i loko o ka pahu kaulike oxygen.

Ke hoʻomau nei ke kaʻina hana adsorption, hele mālie nā mea adsorbent i ka saturation. I kēia manawa, hoʻololi ka ʻōnaehana i kahi pae hana hou. ʻO ka pahu hoʻololi e kuhikuhi i ke kahe ma ka ʻaoʻao ʻē aʻe, a ʻo kahi pahu ʻūhā e hoʻemi i ke kaomi i ka hale kiaʻi i 0.65-0.75 BARG. Hoʻokuʻu ʻia kēia ʻano vacuum i nā mea haumia adsorbed, a laila hoʻokuʻu ʻia i ka lewa, e hoʻoulu hou i ka adsorbent no ka pōʻai hou.

ʻO kaVPSA oxygen generatorua hoʻolālā ʻia no ka hana mau ʻana, e hāʻawi ana i kahi lako paʻa o ka oxygen maʻemaʻe kiʻekiʻe. ʻO kona kūpono a me ka hilinaʻi e lilo ia i mea koʻikoʻi i nā ʻoihana like ʻole, me ka lāʻau lapaʻau, ka hana ʻana, a me ka metallurgy. ʻO ka hiki ke hana i ka oxygen ma ka pūnaewele e hōʻemi i nā pilikia logistical a me nā kumukūʻai e pili ana i nā ʻano hāʻawi oxygen kuʻuna, e like me ka hāʻawi ʻana i ka wai a i ʻole ka hoʻopuka kinoea.

Eia kekahi, hiki ke hoʻonui ʻia ka ʻenehana VPSA, e ʻae ana i nā hoʻoponopono e hoʻokō i nā pae koi oxygen like ʻole. ʻO kēia maʻalahi, i hui pū ʻia me kāna mau pōmaikaʻi kaiapuni a me ka uku-pono, hoʻonoho i ka VPSAO₂mea kanu hanama ke ʻano he alakaʻi alakaʻi no ka hoʻokumu ʻana o ka oxygen i ka ʻāina ʻoihana hou. Ke hoʻomau nei nā ʻoihana e ʻimi i nā ʻano hana hoʻomau a me ka maikaʻi, kū ka mea kanu oxygen VPSA ma ke ʻano he ʻenehana noʻonoʻo i mua e hoʻokō nei i kēia mau koina me ka hōʻoia ʻana i ka hāʻawi mau ʻana o ka oxygen kiʻekiʻe.
