Pehea e loaʻa ai ke kinoea nitrogen maʻemaʻe kiʻekiʻe mai Air？
1. Cryogenic ea hoʻokaʻawale ala
ʻO ke kaʻina hana hoʻokaʻawale Cryogenic ua hala ma mua o 100 mau makahiki o ka hoʻomohala ʻana, a ua ʻike i nā ʻano kaʻina hana like ʻole e like me ke kiʻekiʻe kiʻekiʻe, kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, ke kaomi waena, a me ke kaʻina hana haʻahaʻa haʻahaʻa. Me ka hoʻomohala ʻana o ka ʻenehana helu ea hou a me nā mea hana, ua hoʻopau maoli ʻia ke kaʻina hana o ke kiʻekiʻe-voltage, ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, a me ka medium-voltage vacuum. ʻO ke kaʻina hana haʻahaʻa haʻahaʻa haʻahaʻa me ka hoʻohana ʻana i ka ikehu haʻahaʻa a me ka hana palekana i lilo i mea koho mua no nā ʻenehana haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa. Hoʻokaʻawale ʻia ke kaʻina hana hoʻokaʻawale haʻahaʻa haʻahaʻa haʻahaʻa i loko o nā kaʻina hana hoʻoemi waho a me nā kaʻina hana hoʻoemi kūloko e like me nā loulou hoʻopili like ʻole o ka oxygen a me nā huahana nitrogen. ʻO ka piha haʻahaʻa haʻahaʻa haʻahaʻa waho hoʻoemi kaʻina hana haʻahaʻa -pressure oxygen a i ʻole nitrogen, a laila kaomi i ke kinoea huahana i ke koi koi e hoʻolako i ka mea hoʻohana ma o kahi compressor waho. ʻO ke kaomi piha i ke kaʻina hana hoʻoemi haʻahaʻa ʻO ka oxygen wai a i ʻole ka wai nitrogen i hana ʻia e ka distillation distillation e ʻae ʻia e nā pamu wai i loko o ka pahu anuanu e vaporize ma hope o ke kaomi i koi ʻia e ka mea hoʻohana, a hāʻawi ʻia ka mea hoʻohana ma hope o ka wela hou ʻana i ka mea hoʻololi wela nui. ʻO nā kaʻina hana nui ke kānana, hoʻoemi, hoʻoluʻu, hoʻomaʻemaʻe, supercharger, hoʻonui, distillation, hoʻokaʻawale, wela - reunion, a me ka lako waho o ka ea maka.
2. ke ʻano hoʻoheheʻe ʻana i ke kaomi (PSA method)
Hoʻokumu ʻia kēia ʻano ma luna o ka ea paʻa e like me ka mea maka. ʻO ka maʻamau, hoʻohana ʻia ka molecular screening e like me ka adsorbent. Ma lalo o kekahi kaomi, hoʻohana ʻia ka ʻokoʻa o ka absorption o ka oxygen a me nā molekala nitrogen i ka lewa i nā kānana molecular like ʻole. I ka hōʻiliʻili o ke kinoea, hoʻokō ʻia ka hoʻokaʻawale ʻana o ka oxygen a me ka nitrogen; a ʻo ka molecular sieve absorbing agent i kālailai ʻia a hana hou ʻia ma hope o ka wehe ʻana i ke kaomi.
Ma waho aʻe o nā kānana molekula, hiki i nā adsorbents ke hoʻopili i ka alumina a me ke silicone.
I kēia manawa, hoʻohana ʻia ka mea hana maʻamau o ka mea hoʻololi adsorption nitrogen ma luna o ka ea paʻa, carbon molecular sieve e like me ka adsorbent, a hoʻohana i nā ʻokoʻa i ka hiki adsorption, adsorption rate, adsorption ikaika o ka oxygen a me ka nitrogen ma nā kānana molekala kalapona a ʻO ke koʻikoʻi ʻokoʻa he ʻokoʻa nā hiʻohiʻona adsorption e hiki ai ke hoʻokaʻawale i ka oxygen a me ka nitrogen. ʻO ka mea mua, ʻo ka oxygen i ka lewa ka mea mua e nā molekala kalapona, kahi e hoʻonui ai i ka nitrogen i ka pae kinoea. I mea e loaʻa mau ai ka nitrogen, pono ʻelua hale kiaʻi adsorption.
Palapala noi
1. Pa'a loa ka waiwai kemika o ka naikokene a 'a'ole pane i na mea 'ē a'e. ʻO kēia ʻano inertial e hiki ai ke hoʻohana nui ʻia i nā kaiapuni anaerobic he nui, e like me ka hoʻohana ʻana i ka nitrogen e pani i ka ea i loko o kahi pahu kikoʻī, e pāʻani ana i kahi kaʻawale, pale ahi, explosion-proof, a me anticorrosion. Hoʻohana ʻia ka ʻenekinia LPG, nā pipeline gas a me nā pūnaewele bronchial liquefied i ka noi o nā ʻoihana a me ka hoʻohana kīwila [11]. Hiki ke hoʻohana ʻia ka Nitrogen i loko o ka hoʻopaʻa ʻana i nā meaʻai i hana ʻia a me nā lāʻau lapaʻau e like me ka uhi ʻana i nā kinoea, nā kaula hoʻopaʻa, nā laina kelepona, a me nā kaʻa paʻi paʻi hiki ke hoʻonui. Ma ke ʻano he mea mālama, hoʻololi pinepine ʻia ka nitrogen me lalo o ka lepo e hoʻolohi i ka ʻino i hana ʻia e ka pilina ma waena o ke kolamu paipu a me ka wai stratum.
2. High -purity nitrogen ua hoʻohana 'ia i loko o ka metala hehee hoolei kaʻina hana e hoʻomaʻemaʻe i ka metala hehee e hoʻomaikaʻi i ka maikaʻi o ka hoolei blank. ʻO ke kinoea, pale pono ia i ka wela wela o ke keleawe, mālama i ka ʻili o ka mea keleawe, a hoʻopau i ke kaʻina hana pickling. ʻO ke kinoea umu ahi lanahu (ʻo kona haku ʻana: 64.1%N2, 34.7%CO, 1.2%H2 a me kahi wahi liʻiliʻi o CO2) ma ke ʻano he kinoea pale i ka wā e hoʻoheheʻe ai ke keleawe, no laila e hoʻohana ʻia ka maikaʻi o ka huahana.
3. Ma kahi o 10% o ka naikokene i hana ʻia ma ke ʻano he refrigerant, ʻo ia ka mea: maʻamau a palupalu a like paha me ka rubber -like solidification, haʻahaʻa -temperature processing rubber, contraction anu a me ka hoʻokomo ʻana, a me nā specimens biological, e like me ka mālama ʻana i ke koko Cool i ka lawe ʻana.
4. Hiki ke hoʻohana ʻia ka Nitrogen e synthesize i ka nitric oxide a i ʻole nitrogen dioxide e hana i ka waikawa nitric. He kiʻekiʻe kēia ʻano hana hana a haʻahaʻa ke kumukūʻai. Eia kekahi, hiki ke hoʻohana ʻia ka nitrogen no ka ammonia synthetic a me ka nitride metala.
