ʻO ka ʻokoʻa ma waena o VPSA oxygen generator a me PSA oxygen generator

Ke piʻi pono nei, VPSA (low pressure adsorption vacuum desorption) oxygen production kekahi "ʻokoʻa" oPSA oxygen hana, Ua aneane like ko lakou oxygen hana kumu, a ua hoʻokaʻawale 'ia ke kinoea hui 'ia e ka okoa i ka hiki o ka molecular kānana e "adsorb" okoa kinoea molekele. Akā ʻo ke kaʻina hana oxygen PSA ma o ka pressurize adsorption, ka hoʻoneʻe ʻana o ka lewa e hoʻokaʻawale i ka oxygen. ʻO ke kaʻina hana VPSA o ka hana oxygen ʻo ia ka desorption saturated molecular sieve ma lalo o nā kūlana vacuum.

ʻOiai ua hoʻokumu ʻia nā mea ʻelua i ka ea ma ke ʻano he mea maka, ua like ke kumu o ka hana oxygen. Akā, i ka hoʻohālikelike pono ʻana, aia kēia mau ʻokoʻa;

1. KaVPSA oxygen generatorhoʻohana i ka blower e kiʻi i ka ea maka a kaomi iā ia, ʻoiai ka PSA oxygen generator e hoʻohana i ka ea compressor e hoʻolako i ke kinoea.

2, Ma ka mea nui - zeolite molecular sieve koho, PSA oxygen generator hoʻohana sodium molecular sieve a VPSA oxygen generator hoʻohana i ka lithium molecular sieve.

3. ʻO ke kaomi adsorption o PSA oxygen generator ka mea maʻamau 0.6 ~ 0.8Mpa, a ʻo ke kaomi adsorption o VPSA oxygen generator he 0.05Mpa a ʻo ka desorption kaomi -0.05Mpa.

4, hiki i ka PSA hoʻokahi mea kanu kinoea hana hiki ke hiki i 200 ~ 300Nm³ / h, a hiki i ka VPSA hoʻokahi mea kanu kinoea hana hiki ke hiki i 7500 ~ 9000Nm³ / h.

5, VPSA pili i ka PSA, he haʻahaʻa ikehu hoʻohana (hana o 1Nm3 oxygen mana hoʻohana ≤ 0.31kW, oxygen maemae 90%, me ka oxygen compression), a oi kaiapuni.

6, E like me ka hana o ka oxygen, ka hoʻohana ʻana i ka ikehu a me ka hoʻopukapuka e koho i ke kaʻina PSA a i ʻole ke kaʻina VPSA.

ʻO VPSA oxygen generator ʻoiai ʻo ka nui o ka nui o ka mea kanu oxygen i ka nui, akā ʻo kona hemahema ʻoi aku ka paʻakikī o ka ʻōnaehana, ʻoi aku ka nui o ka nui o nā mea hana (e hoʻohālikelike ʻia me ka mea cryogenic ʻoi aku ka liʻiliʻi), nā kūlana kākoʻo a me nā pono. , e noho i kahi ākea nui, ʻaʻole hiki ke hana ʻia i ʻano pahu. A pono ia ma ka paena hoʻonoho, commissioning, mai keia wahi wale. He mau pono ko PSA.
