Hōʻike huahana
Psa oxygen hana lako, ma lalo o ke kūlana o ka lumi lumi a me ka lewa kaomi, hoʻohana i ka VPSA kūikawā molecular kānana e koho koho i ka nitrogen, carbon dioxide a me ka wai a me nā mea haumia ʻē aʻe i ka lewa, i mea e loaʻa ai ka oxygen me ka maʻemaʻe kiʻekiʻe (93±2%). ).
Hoʻohana maʻamau ka hana oxygen kuʻuna i ke ʻano hoʻokaʻawale cryogenic, hiki ke hana i ka oxygen me ka maʻemaʻe kiʻekiʻe. Eia naʻe, he kiʻekiʻe ka waiwai o nā mea hana, a ke hana nei nā mea hana ma lalo o ke kūlana o ke kiʻekiʻe kiʻekiʻe a me ka mahana wela. He paʻakikī ka hana, he kiʻekiʻe ka mālama ʻana, a he kiʻekiʻe ka hoʻohana ʻana i ka ikehu, a pono pinepine ia e hele i nā hola he nui e hana maʻamau i ke kinoea ma hope o ka hoʻomaka ʻana.
Mai ka wā i komo ai nā lako hana oxygen psa i ka ʻoihana, ua ulu wikiwiki ka ʻenehana, no ka mea, ʻoi aku ka maikaʻi o kāna kumukūʻai ma mua o ka haʻahaʻa haʻahaʻa haʻahaʻa a ʻaʻole kiʻekiʻe loa nā koi maʻemaʻe i ke kūlana he ikaika hoʻokūkū, no laila ua hoʻohana nui ʻia i ka hoʻoheheʻe ʻana. ka hoʻonui ʻana i ka oxygen i ka umu ahi, ka hoʻomaʻemaʻe ʻana i ka pulp, ka umu aniani, ka mālama ʻana i ka wai ʻino a me nā māla ʻē aʻe.
Ua hoʻomaka mua ka noiʻi ʻana i kēia ʻenehana, akā i ka wā lōʻihi, ua lohi ka hoʻomohala ʻana.
Mai ka 1990s, ua ʻike lohi ʻia nā pono o nā lako hana oxygen psa e ka poʻe Kina, a i nā makahiki i hala iho nei, ua hoʻokomo ʻia nā kaʻina hana like ʻole.
He kūlana koʻikoʻi ka psa VPSA oxygen production lako o Hangzhou Boxiang Gas Equipment Co., Ltd.
ʻO kekahi o nā kuhikuhi hoʻomohala nui o ka psa e hōʻemi i ka nui o ka adsorbent a hoʻomaikaʻi i ka hiki ke hana o nā mea hana. Eia naʻe, hoʻokō mau ʻia ka hoʻomaikaʻi ʻana o nā kānana molekele no ka hana ʻana o ka oxygen ma ke ʻano o ka nui o ka adsorption nitrogen kiʻekiʻe, no ka mea, ʻo ka hana adsorption o nā kānana molecular ke kumu o PSA.
ʻO ka kānana molekala me ka maikaʻi maikaʻi e loaʻa i ka nui o ka nitrogen a me ka oxygen separation coefficient, ka mana adsorption saturation a me ka ikaika kiʻekiʻe.
ʻO Psa kekahi alakaʻi hoʻomohala koʻikoʻi e hoʻohana i ka pōʻai pōkole, ʻaʻole pono ia e hōʻoia i ka maikaʻi o ka molecular sieve, i ka manawa like e hoʻokumu ʻia ma luna o ka adsorption tower i loko o ka hoʻolālā ʻana i loko, i mea e pale ai i ka mea e hōʻino ai ka huahana. nā hemahema o ka hāʻawi like ʻole ʻana o ka ʻike kinoea i loko o ka hale kiaʻi adsorption, a waiho pū i mua i nā koi kiʻekiʻe no ka hoʻololi ʻana i ka valve lele.
I nā kaʻina hana oxygen PSA he nui, hiki ke hoʻokaʻawale ʻia ʻo PSA, VSA a me VPSA i ʻekolu mau ʻano.
ʻO PSA ke kaʻina hana desorption hau nui nui. Loaʻa iā ia nā pono o ka ʻāpana maʻalahi a me nā koi haʻahaʻa no nā kānana molekala, a me nā hemahema o ka hoʻohana ʻana i ka ikehu kiʻekiʻe, pono e hoʻohana ʻia i nā mea liʻiliʻi.
ʻO VSA, a i ʻole ka lewa kaomi adsorption vacuum desorption kaʻina, loaʻa ka pōmaikaʻi o ka hoʻohana ʻana i ka ikehu haʻahaʻa a me ka hemahema o nā lako paʻakikī a me ka nui o ka hoʻopukapuka kālā.
ʻO VPSA ke kaʻina hana o ka hoʻoheheʻe ʻana ma o ke kaomi lewa. Loaʻa iā ia nā pōmaikaʻi o ka hoʻohana ʻana i ka ikehu haʻahaʻa a me ka hana kiʻekiʻe o ka sieve molecular. ʻOi aku ka haʻahaʻa o ka huina kālā o nā lako ma mua o ke kaʻina VSA, a ʻo nā hemahema he mea kiʻekiʻe nā koi no ka molecular sieve a me ka valve.
Hoʻohana ʻo Hangzhou Boxiang kinoea i ke kaʻina VPSA, a hoʻomaikaʻi maikaʻi i ke kaʻina hana kuʻuna a me ke kaʻina hana, ʻaʻole ia e hōʻemi wale i ka hoʻohana ʻana i ka ikehu i ka liʻiliʻi (e pili ana i ka hoʻohana ʻana i ka sieve molecular mole like), akā hoʻokō pū i ka pahuhopu o ka maʻalahi a me ka miniaturization. o nā lako, ho'ēmi i ka hoʻopukapuka kālā, a he kiʻekiʻe ka hana / kumu kūʻai lākiō.
ʻO ka ʻōnaehana hana oxygen psa holoʻokoʻa i haku ʻia me ka blower, pump vacuum, switching valve, absorber a me ka oxygen pressure booster unit of oxygen balance tank.
Ma hope o ka wehe ʻia ʻana o nā ʻāpana lepo e ka kānana suction, kaomi ʻia ka ea maka i 0.3 ~ 0.4 Barg e Roots blower a komo i kekahi o nā adsorbents.
Hoʻopihaʻia ka adsorbent i ka adsorbent, kahi i hoʻopiliʻia ai ka wai, carbon dioxide, a me kahi liʻiliʻi o nā mea kinoea'ē aʻe ma ka puka o ka adsorbent e ka alumina hoʻonāukiʻia ma lalo, a laila hoʻopiliʻia ka nitrogen e ka alumina a me ka zeolite. ma luna o ke kānana molekala 13X.
ʻO ka oxygen (me ka argon) ka mea i hoʻopili ʻole ʻia a hoʻokuʻu ʻia mai ka puka o luna o ka adsorber i ka pahu kaulike oxygen ma ke ʻano he huahana.
Ke hoʻopili ʻia ka adsorbent i kekahi ʻano, hiki i ka adsorbent ke kūlana saturation. I kēia manawa, e hoʻohana ʻia ka ʻūhā ʻūlū e hoʻomāmā i ka adsorbent ma o ke kīwī hoʻololi (kūʻē i ke kuhikuhi o adsorption), a ʻo ke degere hū he 0.45 ~ 0.5BARg.
ʻO ka wai i hoʻopaʻa ʻia, carbon dioxide, nitrogen a me kahi mea liʻiliʻi o nā ʻāpana kinoea ʻē aʻe e puhi ʻia i loko o ka lewa a hoʻōla hou ʻia ka adsorbent.
Hoʻololi kēlā me kēia adsorber ma waena o nā pae aʻe:
- adsorption
- desorption
- hehi
ʻO nā ʻanuʻu kaʻina hana maʻamau ʻekolu i hoʻokele ʻia e ka PLC a me ka ʻōnaehana valve hoʻololi.
Kumu Hana
ʻO nā ʻanuʻu kaʻina hana maʻamau ʻekolu i hoʻokele ʻia e ka PLC a me ka ʻōnaehana valve hoʻololi.
1. Ke kumu o ka hoʻokaʻawale ʻana i ka ea psa e hana i ka oxygen
ʻO nā mea nui i ka lewa he nitrogen a me ka oxygen. No laila, hiki ke koho ʻia nā adsorbents me nā koho adsorption like ʻole no ka nitrogen a me ka oxygen a hiki ke hoʻolālā ʻia ke kaʻina hana ʻenehana kūpono e hoʻokaʻawale i ka nitrogen a me ka oxygen e hana i ka oxygen.
Loaʻa nā manawa quadrupole ʻelua a me ka oxygen, akā ʻoi aku ka nui o ka manawa quadrupole o ka nitrogen (0.31 A) ma mua o ka oxygen (0.10 A), no laila ʻoi aku ka ikaika o ka hiki ke adsorption ma nā kānana molekala zeolite ma mua o ka oxygen (ʻoi aku ka ikaika o ka nitrogen me nā ion ma ka ʻili. o ka zeolite).
No laila, i ka wā e hele ai ka ea i loko o ka moe adsorption i loaʻa ka zeolite adsorbent ma lalo o ke kaomi, ua hoʻopili ʻia ka nitrogen e ka zeolite, a emi iki ka oxygen, no laila ua hoʻonui ʻia i loko o ke kinoea a kahe mai ka moe adsorption, e hoʻokaʻawale i ka oxygen a me ka nitrogen. loaʻa ka oxygen.
Ke hoʻopili ka molecular sieve i ka nitrogen a kokoke i ka saturation, ua hoʻopau ʻia ka ea a ua hoʻemi ʻia ke kaomi o ka moena adsorption, hiki ke hoʻopau ʻia ka naikokene adsorbed e ka molecular sieve, a hiki ke hoʻohana hou ʻia ka kānana molekika.
Hiki ke hana mau ʻia ka oxygen ma ka hoʻololi ʻana ma waena o ʻelua mau moena adsorption.
ʻO ka paila o ka argon a me ka oxygen kokoke i kekahi i kekahi, no laila paʻakikī ke hoʻokaʻawale iā lākou, a hiki ke hoʻonui ʻia i loko o ke kinoea.
No laila, hiki i ka psa oxygen production mea maʻamau ke loaʻa i ka manaʻo o 80% ~ 93% oxygen, ke hoʻohālikelike ʻia me ka neʻe ʻana o 99.5% a i ʻole ka oxygen i loko o ka mea hoʻokaʻawale ea cryogenic, i ʻike ʻia ʻo ka oxygen-rich.
E like me nā ʻano desorption like ʻole, hiki ke hoʻokaʻawale ʻia ka hana oxygen psa
ʻElua Kaʻina Hana
1. Kaʻina PSA: kaomi adsorption (0.2-0.6mpa), ka lewa desorption.
He maʻalahi nā mea hana kaʻina PSA, hoʻopukapuka liʻiliʻi, akā hāʻawi haʻahaʻa ka oxygen, hoʻohana nui i ka ikehu, kūpono no ka hana oxygen liʻiliʻi (maʻamau <200m3/h).
2. VPSA kaʻina hana: adsorption ma lalo o maʻamau puʻe a iki iki ma mua o maʻamau kaomi (0 ~ 50KPa), vacuum extraction (-50 ~ -80kpa) desorption.
Ke hoʻohālikelike ʻia me ke kaʻina hana PSA, paʻakikī nā lako kaʻina VPSA, hoʻopukapuka kiʻekiʻe, akā kiʻekiʻe kiʻekiʻe, hoʻohana haʻahaʻa haʻahaʻa, kūpono no nā manawa hana oxygen nui.
No ke kaʻina hana kaʻawale maoli, pono e noʻonoʻo ʻia nā ʻāpana ʻē aʻe i ka lewa.
ʻOi aku ka nui o ka mana adsorption o carbon dioxide a me ka wai ma nā adsorbents maʻamau ma mua o ka nitrogen a me ka oxygen. Hiki ke hoʻopiha ʻia nā adsorbents i loko o ka moena adsorption me nā adsorbents kūpono (a i ʻole ka hoʻohana ʻana i ka oxygen e hana ana i nā adsorbents iā lākou iho) i hiki iā lākou ke komo a wehe ʻia.
ʻO ka ʻike loea maʻamau o nā lako hana oxygen VPSA:
Ø hoʻohana i ka ʻenehana kiʻekiʻe, ka ʻenehana makua, ka hoʻohana ʻana i ka ikehu haʻahaʻa a me nā kumukūʻai hana o ʻelua kaʻina hale kiaʻi psa oxygen generation process;
Ø noʻonoʻo a, ma o ka nānā ʻana i kahi hoʻonohonoho piha o nā lako, kiʻekiʻe kiʻekiʻe e hōʻoia i ka hilinaʻi a me ka paʻa o ka hana ʻōnaehana;
Ø mea hana, maʻalahi ka hana maʻalahi;
Ø ka mana kaʻina hana automated, ka hoʻokele kikowaena o ka lumi hoʻomalu waena;
ʻO ka palekana ʻōnaehana Ø maikaʻi, ka nānā ʻana i nā lako, nā hana pale hewa e hoʻomaikaʻi ai;
Ø me ka haumia ʻole o ke kaiapuni;
Ø ʻO nā lako oxygen e hoʻokō i ka hoʻolaha hope loa o ka People's Republic of China nā kūlana aupuni a me ke kūlana kuhina o ka ʻoihana mechanical.
