I kēia manawa, ke paipai piha nei ka ʻoihana ʻoihana o Kina i ka mālama ʻana i ka ikehu a me ka hoʻololi ʻana i ka hōʻemi kalapona. Ua lilo ka hana ʻana o ka oxygen ma kahi e pani ai i ka oxygen ʻōmole a me ka oxygen wai i mea e pono ai no ka hōʻemi ʻana i ke kumukūʻai ma nā hale hana nui, a ke piʻi nei ka nui o ke kau ʻana o nā lako hana oxygen PSA/VPSA ma kahi i kēlā me kēia makahiki. Eia nō naʻe, aia kahi pilikia nui i ka ʻoihana: nui nā ʻoihana e alualu makapō ana i ka oxygen maʻemaʻe kiʻekiʻe, e hoʻonui pono ʻole ana i nā hoʻopukapuka lako a me nā kumukūʻai uila; a ma kekahi mau kūlana hana, ʻaʻole i kūlike ka maʻemaʻe o ka oxygen me nā kūlana, e alakaʻi ana i ka emi ʻana o ka pono hana a me ka hoʻonui ʻana i nā helu hemahema huahana.
ʻAʻole ʻoi aku ka maikaʻi o ka maʻemaʻe o ka oxygen kiʻekiʻe i nā manawa a pau. Loaʻa i nā kaʻina hana like ʻole a me nā ʻoihana ma hope o ka hana nā kūlana kūlike o ka maʻemaʻe. Ma ka hoʻohui ʻana i ke kūlana aupuni hou loa GB/T 3863-2025 Industrial Oxygen Specification a me nā ʻano loea o nā lako hana oxygen nui, hoʻokaʻawale piha kēia ʻatikala i nā pae maʻemaʻe ʻelima o ka oxygen ʻoihana, nā lako hana oxygen e pili ana, a me nā hiʻohiʻona kūpono no nā ʻoihana āpau. Hoʻopau pū ia i nā kuhi hewa koho maʻamau e kōkua i nā ʻoihana ʻoihana a me nā ʻoihana mining e koho pololei i nā lako a kāohi pono i nā kumukūʻai kinoea.
1. Haʻahaʻa ka maʻemaʻe (90% ~ 93%):Kūpono no nā hiʻohiʻona puhi ʻana i hoʻonui ʻia i ka oxygen kahi ʻaʻole kiʻekiʻe nā koi o ka nui o ka oxygen. 1. Oxygen no ka hoʻonui ʻana i ke ahi i loko o nā umu aniani, nā umu wili sima, a me nā mea puhi ʻōpala:** Manaʻo kēia e hoʻonui i ka mahana o ka lapalapa a hōʻemi i ka hoʻohana ʻana i ka ikehu, me ka ʻole o ka koi ʻana i ka oxygen maʻemaʻe kiʻekiʻe.
2. Maʻemaʻe waena (93% ~ 95%):Hoʻohana pinepine ʻia i ka oxygenation aquaculture, ka hoʻomehana ʻana o ka wai ʻino, a me kekahi mau hopena oxidation kemika liʻiliʻi. Ua lawa kēia maʻemaʻe no nā kaʻina hana aerobic biological a i ʻole nā kaʻina hana oxidation maʻamau, e hāʻawi ana i ke kumukūʻai kiʻekiʻe loa.
3. Maʻemaʻe kiʻekiʻe (≥99.2% - 99.6%):ʻO ke kūlana papa ʻoihana ʻekahi, kūpono no ka hoʻopili ʻana a me ka ʻoki ʻana i ka metala, ka hana kila metallurgical (e like me ka puhi ʻana o ka oxygen converter), ka hana kemika (e like me ka oxidation ethylene), a me nā kaʻina hana ʻē aʻe e pono ai nā hopena oxidation ikaika a i ʻole e pono ai ka pale mai nā haumia.
4. Maʻemaʻe kiʻekiʻe loa (≥99.9%):Hoʻohana ʻia i ka hana semiconductor, ka hana preform fiber optical, nā propellants aerospace, a me nā kemika maikaʻi kūikawā. He mea maʻalahi loa kēia mau hiʻohiʻona i nā haumia e like me ka makū a me nā hydrocarbons, e koi ana i ka hoʻomaʻemaʻe hohonu.
Nā Mālama Koʻikoʻi:
1. Pāpā loa i ka hoʻohuihui ʻana: Hiki i ka oxygen ʻoihana ke loaʻa nā ʻāpana liʻiliʻi o ke kalapona monoxide, kalapona ʻokikene, acetylene, a me ka ʻaila, akā ʻaʻole loa e hoʻohana ʻia no ka hanu lapaʻau, inā ʻaʻole e hoʻonāukiuki ia i ka māmā, ka lāʻau make, a i ʻole ka edema pulmonary.
2. Hoʻoholo ke kaʻina hana i ka maʻemaʻe: Hoʻokō maʻalahi ka hoʻokaʻawale ʻana o ka ea cryogenic i ka maʻemaʻe kiʻekiʻe (≥99.5%), ʻo ka adsorption swing pressure (PSA) e hana maʻamau i ka maʻemaʻe 90%-95%, a ʻo ka hoʻokaʻawale ʻana o ka membrane ka maʻemaʻe haʻahaʻa loa (30%-50%). Pono ke koho e kūlike me nā koi pālua o ka maʻemaʻe a me ka nui o ke kinoea no ke kūlana kikoʻī.
3. Nā ʻokoʻa maʻamau: ʻO ke kūlana aupuni GB/T 3863 e koi ana he ≥99.5% ka pae oxygen ʻoihana I, a he ≥99.2% ka pae II. Ma nā hana kūpono, inā ʻaʻohe kapu kūikawā o ke kaʻina hana i nā mea haumia, ua lawa ka 93% no ka hapa nui o nā pono kuni a me ka mahi ʻana i ka wai. ʻAʻohe pono e alualu makapō i ka maʻemaʻe kiʻekiʻe e mālama i nā kumukūʻai.
ʻEkolu mau manaʻo kuhihewa i hoʻohana pinepine ʻia no ke koho ʻana i ka ʻoihana:
Kuhihewa 1: ʻO ke kiʻekiʻe o ka maʻemaʻe o ka oxygen ʻo ia hoʻi nā hopena hana maikaʻi aʻe. ʻOiaʻiʻo: ʻO kēlā me kēia 1% piʻi ʻana o ka maʻemaʻe e hoʻonui nui i ka hoʻohana ʻana i ka mana o ka mea hana oxygen. Ua lawa ka 93% oxygen no nā kaʻina hana maʻamau i nā mea kūkulu hale, ka mālama ʻana i ka wai ʻino, a me nā pila lithium. ʻO ke koho makapō ʻana i ka 99.5% oxygen maʻemaʻe kiʻekiʻe e hoʻonui pololei i nā kumukūʻai uila ma mua o 30%.
Kuhihewa 2: Hiki i nā mea hana oxygen ʻoihana ke pani i ka oxygen lapaʻau. ʻOiaʻiʻo: ʻOiai ma 93% ka maʻemaʻe, ʻaʻohe o nā mea hana oxygen ʻoihana i nā mea hoʻomaʻemaʻe kinoea lapaʻau a me nā mea kānana a loaʻa nā haumia e like me ka makū a me ka lepo. Ua pāpā loa ʻia lākou mai ka hoʻohana ʻia ʻana no ka hoʻolako ʻana i ka oxygen hanu kanaka. Pili nā mea ʻelua i nā kūlana palekana ʻokoʻa loa.
ʻŌlelo Hoʻopunipuni 3: Pono nā kūlana kākoʻo puhi a pau i ka oxygen maʻemaʻe kiʻekiʻe. ʻOiaʻiʻo: No nā umu a me nā paila maʻamau, ua lawa ka hoʻonui ʻana i ka oxygen hoʻokaʻawale membrane 25%-40%, e hāʻawi ana i ka maikaʻi o ke kumukūʻai ma mua o nā mea hana oxygen sieve molekala. ʻO ke koho ʻana i ke kumu hoʻohālike kūpono no kāu mau pono kikoʻī ke kī i ka hōʻemi ʻana i ke kumukūʻai.
Hōʻuluʻulu manaʻo:ʻO ke kumumanaʻo koʻikoʻi no ke koho ʻana i nā mea hana oxygen ʻoihana: kūpono no nā kūlana hana, ʻaʻole pono ke kiʻekiʻe o ka maʻemaʻe. No ke kākoʻo kuni kumu, kūpono ka hoʻonui ʻana i ka oxygen hoʻokaʻawale membrane; no ka hana ʻoihana maʻamau, ua ʻōlelo ʻia he 93% nā mea hana oxygen PSA maʻamau; ʻo nā kaʻina hana kiʻekiʻe wale nō e koi ana i ka oxygen maʻemaʻe kiʻekiʻe cryogenic o 99.5% a ʻoi aku paha. Ma mua o ke kūʻai ʻana i nā mea hana oxygen, pono nā ʻoihana e wehewehe pono i kā lākou mau koi maʻemaʻe kinoea hana a me ka nui o ke kahe e hoʻokō maoli i ka hana palekana a me ka mālama ikehu.
