Nā hiʻohiʻona huahana o PSA nitrogen generator

Me ka hoʻomohala wikiwiki ʻana o ka ʻoihana, ua hoʻohana nui ʻia ka nitrogen ma nā ʻano o nā kemika, nā mea uila, nā metallurgy, nā meaʻai, nā mīkini, a me nā mea ʻē aʻe.ʻAʻole hana kemika ʻo Nitrogen, a paʻa loa ia ma lalo o nā kūlana maʻamau, a ʻaʻole maʻalahi ke hana kemika me nā mea ʻē aʻe.No laila, hoʻohana nui ʻia ka nitrogen e like me ke kinoea pale a me ka hoʻopaʻa ʻana i ke kinoea i ka ʻoihana metallurgical, ʻoihana uila, a me ka ʻoihana kemika.ʻO ka maʻamau, ʻo ka maʻemaʻe o ke kinoea pale he 99.99%, a ʻo kekahi e koi ana i ka nitrogen maʻemaʻe kiʻekiʻe ma mua o 99.998%.ʻOi aku ka maʻalahi o ka wai hau hau, a ʻoi aku ka maʻalahi o ka hoʻohana ʻana i ka ʻoihana meaʻai, ka ʻoihana lapaʻau, a me ka mālama ʻana i ka pua o ka mahiʻai holoholona.I ka hana ʻana o ka amonia synthetic i ka ʻoihana mea kanu kemika, inā holoi ʻia a hoʻomaʻemaʻe ʻia ke kinoea maka o ka ammonia synthetic-hydrogen a me nā kinoea i hui pū ʻia me ke kinoea wai maʻemaʻe, hiki ke liʻiliʻi loa ka ʻike o ke kinoea inert, a me ka ʻike o ka sulfur. ʻAʻole ʻoi aku ka nui o ka monoxide a me ka oxygen ma mua o 20 ppm.

ʻAʻole hiki ke huki pololei ʻia ka nitrogen maʻemaʻe mai ke ʻano, a hoʻohana nui ʻia ka hoʻokaʻawale ʻana o ka ea.ʻO nā ʻano hana hoʻokaʻawale ea he: cryogenic method, pressure swing adsorption method (PSA), membrane separation method.

Hoʻomaka i ke kaʻina hana a me nā mea hana o PSA nitrogen generator

Hoʻolauna i ke kahe kaʻina

Hoʻokomo ka ea i ka ea compressor ma hope o ka wehe ʻana i ka lepo a me nā mea ʻino mechanical ma o ka kānana ea, a ua hoʻopili ʻia i ke kaomi koi.Ma hope o ka hoʻomaʻemaʻe ʻana i ka hoʻomaʻemaʻe ʻana, hoʻomaʻemaʻe ʻia, a me ka hoʻomaʻemaʻe ʻana i ka lepo, hoʻopuka ʻia ka ea i hoʻopaʻa ʻia maʻemaʻe e hōʻoia i ka hoʻohana ʻana i nā kānana molekala i ka hale kiaʻi adsorption.ola.

Aia ʻelua mau hale kiaʻi adsorption i hoʻolako ʻia me ka kānana molekala kalapona.Ke hana nei kekahi hale kiaʻi, hoʻopau ʻia ka hale kiaʻi ʻē aʻe no ka desorption.Ke komo nei ka ea maʻemaʻe i ka hale kiaʻi adsorption hana, a i ka wā e hele ai i loko o ka molecular sieve, oxygen, carbon dioxide a me ka wai e adsorbed e ia.ʻO ke kinoea e kahe ana i ka hopena puka he nitrogen a me ka nui o ka argon a me ka oxygen.

ʻO kekahi hale kiaʻi (desorption tower) e hoʻokaʻawale i ka oxygen adsorbed, carbon dioxide a me ka wai mai nā pores o ka molecular sieve a hoʻokuʻu iā ia i ka lewa.Ma kēia ala, lawe ʻia nā hale kiaʻi ʻelua e hoʻopau i ka hoʻokaʻawale ʻana o ka nitrogen a me ka oxygen a hoʻomau i ka hoʻopuka ʻana i ka nitrogen.ʻO ka maʻemaʻe o ka nitrogen i hoʻopuka ʻia e ke kaomi ʻana (_bian4 ya1) adsorption he 95% -99.9%.Inā makemake ʻia ka nitrogen maʻemaʻe kiʻekiʻe, pono e hoʻohui ʻia nā mea hoʻomaʻemaʻe nitrogen.

ʻO ka 95% -99.9% nitrogen output mai ke kaomi swing adsorption nitrogen generator komo i ka mea hoʻomaʻemaʻe nitrogen, a ma ka manawa like i hoʻohui ʻia ka nui kūpono o ka hydrogen ma o ka flowmeter, a me ka hydrogen a me ka oxygen trace i loko o ka nitrogen e catalytically reacted i loko. ʻO ka hale kiaʻi deoxygenation o nā mea hoʻomaʻemaʻe e wehe ai Hoʻomaʻalili ʻia ka oxygen e kahi condenser wai, hoʻoheheʻe ʻia ka mea hoʻokaʻawale wai mahu, a laila maloʻo hohonu e kahi mea maloʻo (hoʻohana ʻia ʻelua mau hale kiaʻi hoʻomaloʻo adsorption: hoʻohana ʻia kekahi no ka adsorption a ʻO ka hoʻomaloʻo ʻana e wehe i ka wai, ua wela ka ʻē aʻe no ka desorption a me ka drainage e loaʻa ai ke kiʻekiʻe-maʻemaʻe nitrogen. ʻO ka maʻemaʻe o ka naikokene hiki ke hiki i 99.9995%. I kēia manawa, ʻo ka nui loa o ka hana ʻana o ke kaomi swing adsorption nitrogen i ka honua he 3000m3n/h.
