He ʻenehana hoʻokaʻawale kinoea kiʻekiʻe ka nitrogen generator.Hoʻohana ʻia ka sieve carbon molecular sieve (CMS) kiʻekiʻe i lawe ʻia e like me ka adsorbent, a ua hoʻomākaukau ʻia ke kinoea nitrogen maʻemaʻe kiʻekiʻe ma ka hoʻokaʻawale ʻana i ka ea ma ka mahana maʻamau ma lalo o ke kumu o ke kaomi swing adsorption (PSA).
ʻOkoʻa ka nui o ka diffusion o ka oxygen a me nā molekala kinoea nitrogen ma ka ʻili o ka sieve molecular.ʻOi aku ka wikiwiki o ka hoʻopuehu ʻana o nā molekele kinoea me nā anawaena liʻiliʻi (O2), ʻoi aku ka nui o nā micropores e komo ana i ke kānana mole kalapona, a me ka laiki diffusion o nā molekele kinoea anawaena nui (N2).ʻOi aku ka lohi, liʻiliʻi nā micropores e komo ana i ke kānana molekala kalapona.ʻO ka koho adsorption ʻokoʻa ma waena o ka nitrogen a me ka oxygen e ka carbon molecular sieve e alakaʻi i ka hoʻonui ʻana o ka oxygen i ka pae adsorption i kahi manawa pōkole, ka hoʻonui ʻana o ka nitrogen i ka manawa kinoea, no laila ua hoʻokaʻawale ʻia ka oxygen a me ka nitrogen, a hoʻonui ʻia ke kinoea. loaʻa ka nitrogen ma lalo o ke kūlana PSA.
Ma hope o kekahi manawa, ua kaulike ka adsorption o ka oxygen e ka molecular sieve.E like me ka like ole adsorption hiki o ka carbon molecular sieve i ke kinoea adsorbed ma lalo o ka like 'ole puʻe, ua hoʻohaʻahaʻa 'ia ke kaomi e deactivate ka carbon molecular kānana, a me ke kaʻina hana regeneration.E like me ka ʻokoʻa o ka hoʻoulu hou ʻana, hiki ke hoʻokaʻawale ʻia i loko o ka hoʻōla hou ʻana a me ka hoʻoulu hou ʻana o ka lewa.ʻO ka hoʻoulu hou ʻana o ka lewa e hoʻomaʻamaʻa i ka hana hou ʻana o nā kānana molekala, e maʻalahi ai ka loaʻa ʻana o nā kinoea maʻemaʻe kiʻekiʻe.
ʻO ka puʻupuʻu puʻupuʻu adsorption nitrogen generator (i kapa ʻia ʻo PSA nitrogen generator) he mea hana hoʻoheheʻe nitrogen i hoʻolālā ʻia a hana ʻia e like me ka ʻenehana adsorption pressure swing.ʻO ka mea maʻamau, ua pili like nā hale kiaʻi adsorption ʻelua, a ʻo ka ʻōnaehana hoʻokele ʻakomi e hoʻomalu pono i ka manawa e like me kahi kaʻina programmable kikoʻī, hoʻokō i ke kaomi adsorption a me ka decompression regeneration, hoʻopau i ka hoʻokaʻawale ʻana o ka nitrogen a me ka oxygen, a loaʻa i ke kinoea nitrogen kiʻekiʻe.
