He pai te tihi, ko te VPSA (te whakaheke i te pehanga iti o te whakahekenga korehau) te hanga hāora tetahi atu "rereke" oPSA hanga hāora, he rite tonu ta ratou kaupapa hanga hāora, a ka wehea te ranunga hau e te rereketanga o te kaha o te tatari molecular ki te "adsorb" nga momo ngota hau.Engari ko te mahi hanga hāora PSA na roto i te whakakorikori pehanga, te pehanga o te hau ki te wehe i te hāora.Ko te tukanga VPSA o te hanga hāora ko te whakakore i te tatari rāpoi kukū i raro i nga tikanga korehau.
Ahakoa ko nga mea e rua i runga i te hau hei rauemi mata, he rite tonu te kaupapa o te hanga hāora.Engari ki te whakataurite marie, kei reira nga rereketanga e whai ake nei;
1. TeVPSA hāora generatorka whakamahi i te pupuhi ki te tiki hau mata me te pehi, i te wa e whakamahia ana e te kaiwhakaputa hāora PSA he compressor hau hei tuku hau.
2, I roto i te waahanga matua - te whiriwhiringa tatari molecular zeolite, PSA oxygen generator ka whakamahi i te konutai molecular sieve me te VPSA oxygen generator e whakamahi ana i te tatari molecular lithium.
3. Ko te pēhanga adsorption o PSA hāora generator ko te tikanga 0.6 ~ 0.8Mpa, me te pēhanga adsorption o VPSA hāora generator ko 0.05Mpa me te pēhanga desorption ko -0.05Mpa.
4, Ka taea e te PSA kotahi te tipu te kaha o te hanga hau ki te 200 ~ 300Nm³ / h, me te VPSA kotahi te kaha o te tipu hau ka taea te eke ki te 7500 ~ 9000Nm³ / h.
5, VPSA whanaunga ki PSA, he iti kohi pūngao (production o 1Nm3 hāora kohi mana ≤ 0.31kW, hāora purenga 90%, kahore kōpeketanga hāora), me te ake taiao.
6, E ai ki te hanga hāora, paerewa kohi pūngao me te haumi ki te whiriwhiri i te tukanga PSA, te tukanga VPSA ranei.
VPSA oxygen generator ahakoa he nui te kaha o te tipu kotahi o te hāora hanga, engari ko tana ngoikoretanga he uaua ake nga taputapu punaha, he nui ake te ruri o nga taputapu (whakaritea ki te taputapu cryogenic he iti tonu), he nui ake nga tikanga tautoko me nga taputapu. , ka noho ki te waahi nui ake, kaore e taea te hanga hei ipu.A me whakauru ki runga i te waahi, ki te komihana, mai i tenei wa anake.Kei a PSA etahi painga.
