ʻOihana hana oxygenʻO nā mea hana, e like me ka inoa, nā mea hana i hoʻohana ʻia i ka hana ʻoihana e hana i ka oxygen.
No laila he aha ke ʻano o ka hana oxygen ʻoihana?
Hoʻohana maʻamau mākou i ke ʻano o ka hana ʻana i ka oxygen ma ka decomposing hydrogen peroxide a i ʻole potassium permanganate i loko o ka hale hana, nona nā hiʻohiʻona o ka wikiwiki wikiwiki, ka hana maʻalahi a me ka hōʻiliʻili kūpono o ka mīkini hana oxygen ʻoihana, akā kiʻekiʻe ke kumukūʻai a ʻaʻole hiki ke hana ʻia i ka nui. ka nui, no laila hiki ke hoʻohana wale ʻia i loko o ka hale hana.Pono ka hana ʻoihana e noʻonoʻo inā he mea maʻalahi ka mea hoʻoheheʻe oxygen i ka brand i maʻalahi ke loaʻa, inā he haʻahaʻa ke kumukūʻai, he haʻahaʻa paha ke kumu kūʻai, inā hiki ke hana ʻia i ka nui a me ka hopena i ke kaiapuni.
Ma lalo iho nei ka wehewehe ʻana i nā ʻano kikoʻī ohana ʻoihana oxygen.
1. ʻO ke ʻano o ka hoʻokaʻawale ʻana i ka hau hau
ʻO nā mea nui o ka ea he oxygen a me ka nitrogen.ʻOkoʻa ka hoʻohana ʻana o ka oxygen a me ka nitrogen boiling point, ʻo ka hoʻomākaukau ʻana o ka oxygen mai ka lewa i kapa ʻia ke ʻano hoʻokaʻawale ea.ʻO ka mea mua, ka ea pre-cooling, hoʻomaʻemaʻe (e wehe i kahi liʻiliʻi o ka moisture, carbon dioxide, acetylene, hydrocarbons a me nā kinoea ʻē aʻe a me ka lepo a me nā mea haumia ʻē aʻe i ka lewa), a laila hoʻopaʻa ʻia, hoʻoluʻu, no laila ka ʻumi o luna. nā mana o nā mea hana oxygen i loko o ka ea wai.
A laila, me ka hoʻohana ʻana i ka ʻokoʻa ma waena o nā wahi paila o ka oxygen a me ka nitrogen, e hoʻoheheʻe ʻia ka ea wai a condensed i nā manawa he nui i ka hale kiaʻi distillation e hoʻokaʻawale i ka oxygen a me ka nitrogen.Inā hoʻohui ʻoe i kekahi mau mea hana ʻē aʻe, hiki iā ʻoe ke unuhi i ka argon, neon, helium, krypton, xenon a me nā kinoea inert ʻē aʻe i liʻiliʻi loa i ka lewa.ʻO ka oxygen i hana ʻia e ka mea hoʻokaʻawale ea e hoʻopili ʻia e ka compressor, a ma hope o ka oxygen compressed e hoʻouka ʻia i loko o nā cylinders kiʻekiʻe no ka mālama ʻana, a i ʻole lawe pololei ʻia i nā hale hana a me nā hale hana ma o nā pipeline.
2. Molecular sieve oxygen production method (adsorption method)
Me ka hoʻohana ʻana i nā ʻano o nā molekala nitrogen i ʻoi aku ka nui ma mua o nā molekole oxygen, ua hoʻokaʻawale ʻia ka oxygen i ka lewa me ka hoʻohana ʻana i kahi kānana molekala kūikawā.ʻO ka mea mua, hoʻoikaika ka compressor i ka ea maloʻo ma o ka molecular sieve i loko o ka adsorber vacuum, ua adsorbed nā molekala nitrogen i ka lewa e ka molecular sieve, oxygen i loko o ka adsorber, i ka wā e hiki ai ka oxygen i ka adsorber i kahi nui (piʻi ka pilikia i kekahi. pae), hiki iā ʻoe ke wehe i ka valve oxygen e hoʻokuʻu i ka oxygen.
Ma hope o kekahi manawa, hoʻonui mālie ka nitrogen adsorbed e ka molecular sieve, nāwaliwali ka hiki ʻana o ka adsorption, a emi ka maʻemaʻe o ka oxygen puka, no laila pono e hoʻokuʻu ʻia ka nitrogen adsorbed ma ka molecular sieve e ka paila, a laila e hana hou. ka hana maluna.Ua kapa ʻia kēia ʻano hana o ka oxygen i ke ʻano adsorption.
