Pehea e hana ai ka ʻenehana PSA Oxygen?
Pressure swing adsorption (PSA) oxygen production he ʻenehana hoʻokaʻawale kinoea e pili ana i ke kumu o ka adsorption kino. Hoʻomaʻemaʻe ia i ka oxygen mai ka lewa ma o ka adsorption koho o nā kānana molekala.
Ke Kumu Kumu o PSA Oxygen Production
- Hoʻohana ka PSA oxygen production i ka ʻokoʻa i ka hana adsorption o ka nitrogen a me ka oxygen (i ka lewa) ma ka molecular sieve, a me ke ʻano o ka hoʻololi ʻana o ka mana adsorption me ke kaomi.
- Ma lalo o nā kūlana kaulike, ʻoi aku ka maikaʻi o ke kānana molekala i ka mea hoʻohui nitrogen. Ma lalo o ka hoʻonui ʻana i ke kaomi, ʻoi aku ka kiʻekiʻe o ka adsorption o ka nitrogen ma mua o ka hiki ke adsorption ma ke kaomi haʻahaʻa.
- A hoʻokō ʻia ka desorption regeneration o ka molecular sieve ma ka hoʻololi ʻana i ke kaomi hana, ʻo ia hoʻi, pressurized adsorption a me decompression desorption, a laila e loaʻa ai ka oxygen a me ka hoʻokaʻawale ʻana.
Zeolite Molecular Sieve I Oxygen Production System
- ʻO ka mea nui o ka ʻōnaehana hana oxygen ʻo ka sieve molecular. ʻOiai ʻo ka oxygen a me ka nitrogen he mau mea -polar ʻole, e hana lākou i nā dipoles i hoʻokomo ʻia ma lalo o ka mana o nā kānana molekala zeolite.
- Aia kahi ʻume (ka ikaika inductive) ma waena o ka dipole i hoʻokomo ʻia a me ka dipole kūlohelohe o nā molekole polar. No ka mea, ʻoi aku ka nui o ka ikaika inductive o ka nitrogen ma mua o ka oxygen, ʻoi aku ka nui o ke kānana molecular i ka nitrogen ma mua o ka oxygen.
- Ke hele ka ea i loko o ka kānana zeolite molecular, ʻoi aku ka maikaʻi o ka nitrogen e ka molecular sieve a hoʻonui ʻia i loko o kona micropores, ʻoiai he wahi liʻiliʻi wale nō o ka oxygen i hoʻopili ʻia, a ʻo ka hapa nui o ia mea e hele i ka sieve mole e lilo i kinoea huahana.
Ka Hana Hana O PSA Oxygen Production
- Hoʻopiʻi mua ʻia ka ea e ka -pili ea hana piha a hele i nā kānana he nui e wehe i ka hapa nui o ka lepo a me nā haumia; a laila hoʻomaloʻo ʻia ka ea wela e kahi mea maloʻo maloʻo e hoʻoneʻe i ka wai mai ka lewa; a hope loa, komo ia i loko o ka ea waihona pahu no ka buffering a me ke kaomi stabilization, a komo i ka adsorption hale kiaʻi i hana hou ʻia a ma ke kūlana hana ma o ka pahu hoʻololi.
- I loko o ka hale kiaʻi adsorption, ua hoʻopili ʻia ka nitrogen, carbon dioxide a me nā kinoea ʻē aʻe e nā sieves mole, a hoʻonui ʻia ka oxygen mai luna o ka hale kiaʻi adsorption a komo i ka pahu pahu oxygen. Ma ka pipeline puka o ka pahu hoʻoheheʻe oxygen, hāʻawi ʻia kahi awa hoʻohālike e ʻike i ka maʻemaʻe o ka oxygen. A laila kānana ʻia ka oxygen kūpono ma o kahi kānana lepo a me kahi kānana sterilization no ka loaʻa ʻana o ka oxygen grade{2}}huahana kūpono.
- No ka loaʻa ʻana o ka oxygen pae paʻa -hua, ua lako ka lako PSA oxygen me ʻelua mau hale kiaʻi adsorption no ka hana ʻana i ka oxygen. Ke hoʻopili ʻia kekahi hale kiaʻi a hoʻopuka i ka oxygen, aia ka hale kiaʻi adsorption ʻē aʻe i kahi kūlana hou, a ʻo nā kinoea ʻē aʻe i hoʻokuʻu ʻia e ke kaʻina hana hou e hoʻopau ʻia ma o ka muffler a laila hoʻokuʻu ʻia i waho.
