Vacuum pressure swing adsorption (VPSA) oxygen production technology is a efficient and energy-saving method for prepare oxygen. Loaʻa ia i ka oxygen a me ka nitrogen kaʻawale ma o ka adsorption koho o nā kānana mole. Loaʻa i kāna kahe kaʻina hana nā loulou kumu:
1. Pūnaehana lapaʻau ea maka
Hoʻopiʻi ea: Hoʻopili ka mea puhi i ka ea a puni ma kahi o 63kPa (ke kaomi ana) e hāʻawi i ka mana no ka adsorption ma hope. ʻO ke kaʻina hana hoʻoemi e hoʻohua i ka wela kiʻekiʻe, pono e hoʻomaʻalili i ke kaʻina i makemake ʻia ka mahana (ma kahi o 5-40 ℃) e kahi mea hoʻomaʻamaʻa wai.
Hoʻomaʻemaʻe mua: Hoʻohana ʻia kahi kānana ʻelua-pae no ka wehe ʻana i nā haumia mechanical, a hoʻohana ʻia kahi mea hoʻomaloʻo e wehe i nā mea haumia e like me ka wai a me ka ʻaila noe e pale ai i ka molecular sieve adsorbent.
2. Pūnaehana hoʻokaʻawale adsorption
ʻElua hale kiaʻi hoʻololi adsorption: Ua hoʻolako ʻia ka ʻōnaehana me ʻelua mau hale kiaʻi adsorption i hoʻolako ʻia me nā sieves molecular zeolite. Ke adsorbing kekahi hale kiaʻi, hana hou ʻia ka hale kiaʻi ʻē aʻe. Compressed ea komo mai ka lalo o ka hale kiaʻi, a me ka molecular kānana preferentially adsorbs haumia e like me ka naikokene a me carbon dioxide, a me ka oxygen (maemaʻe 90% -95%) ua puka mai ka luna o ka hale kiaʻi.
Manaʻo kaomi: Mālama ʻia ke kaomi adsorption ma lalo o 55kPa, a loaʻa ka hoʻololi maʻalahi ma o nā valve pneumatic.
3. Desorption a me ka hana hou
ʻO ka hoʻoheheʻe ʻana: Ma hope o ka hoʻohui ʻana, hoʻemi ka paila ʻana i ke kaomi i loko o ka hale kiaʻi i -50kPa, hoʻopau i ka nitrogen a hoʻokuʻu iā ia i loko o ka muffler exhaust.
Hoʻomaʻemaʻe Oxygen: I ka wā hope o ka hana hou ʻana, ua hoʻokomo ʻia kekahi huahana oxygen e hoʻomaʻemaʻe i ka hale kiaʻi adsorption e hoʻomaikaʻi hou i ka pono adsorption o ka pōʻai aʻe.
4.ʻōnaehana hana huahana
Oxygen buffer: Hoʻopaʻa mua ʻia nā huahana oxygen pau ʻole i loko o kahi pahu hoʻopaʻa (ka kaomi 14-49kPa), a laila kaomi ʻia e ka mea hoʻohana e koi ʻia e ka compressor.
Ka hoʻomaʻemaʻe maʻemaʻe: Ma o nā kānana maikaʻi a me ka mālama ʻana i ke koena kahe, e hōʻoia ʻia ka puka o ka oxygen paʻa.
5.Pūnaehana mana akamai
E hoʻohana i ka PLC e hoʻokō i ka hana maʻalahi, me nā hana e like me ka nānā ʻana i ke kaomi, ka hoʻāla hewa, ka hoʻohana ʻana i ka ikehu, a me ke kākoʻo ʻana i ka nānā mamao.
Hoʻokuʻu ke kaʻina hana i ka pōʻai adsorption-desorption ma o nā loli kaomi. Hoʻohālikelike ʻia me ka ʻenehana PSA kuʻuna, hoʻemi nui ke kōkua ʻana i ka ʻenekini (ma kahi o 0.32-0.38kWh/Nm³). Ua hoʻohana nui ʻia i ke kila, kemika, ka lāʻau lapaʻau a me nā māla ʻē aʻe, a kūpono loa ia no nā hiʻohiʻona koi o ka oxygen medium a me ka nui.
Ua kūpaʻa ʻo NUZHUO GROUP i ka noiʻi noiʻi, nā lako hana a me nā lawelawe piha o nā huahana hoʻokaʻawale ea maʻamau, e hāʻawi ana i nā ʻoihana ʻenehana kiʻekiʻe a me nā mea hoʻohana huahana kinoea honua me nā hopena kinoea kūpono a piha e hōʻoia i ka loaʻa ʻana o ka huahana maikaʻi loa. Inā makemake ʻoe e ʻike i nā ʻike pili a i ʻole nā pono, e ʻoluʻolu e kelepona mai iā mākou
