I tēnei wā, kei te whakatairanga whānuitia e te rāngai ahumahi o Haina te tiaki pūngao me te whakaiti waro. Ko te hanga hāora i te papaanga hei whakakapi i te hāora pounamu me te hāora wai kua noho hei mea nui hei whakaiti i ngā utu i roto i ngā wheketere nui, ā, kua piki haere te rahinga tāutanga o ngā taputapu hanga hāora PSA/VPSA i te papaanga i ia tau. Heoi, he raruraru nui kei roto i te umanga: he maha ngā kamupene e whai ana i te hāora parakore teitei, e whakapiki ana i te haumi taputapu me ngā utu hiko; ā, i roto i ētahi āhuatanga whakahaere, kāore te parakore o te hāora e tutuki i ngā paerewa, e arahi ana ki te hekenga o te pai o te whakaputa me te pikinga o ngā reiti hapa hua.
Ehara i te mea he pai ake te parakore o te hāora i ngā wā katoa. He tino pakari ngā paerewa taurite parakore o ngā tukanga whakaputa me ngā ahumahi o raro. Mā te whakakotahi i te paerewa ā-motu hou GB/T 3863-2025 Industrial Oxygen Specification me ngā tawhā hangarau o ngā taputapu whakaputa hāora matua, ka whakarārangihia e tēnei tuhinga ngā taumata parakore e rima o te hāora ahumahi, ngā taputapu whakaputa hāora e rite ana, me ngā horopaki e tika ana mō ngā ahumahi katoa. Ka wetewetehia hoki ngā whakaaro hē o te kōwhiringa hei āwhina i ngā umanga ahumahi me te keri ki te whiriwhiri tika i ngā taputapu me te whakahaere tika i ngā utu hau.
1. He iti te parakore (90%~93%):He pai mō ngā āhuatanga tahunga e whakanuia ana te hāora ina kore e nui te kukū o te hāora e hiahiatia ana. 1. Hāora hei whakarei ake i te tahunga i roto i ngā oumu karāhe, ngā oumu hurihuri sima, me ngā oumu tahu para:** Ko te whāinga o tēnei he whakanui ake i te pāmahana mura me te whakaiti i te whakapaunga pūngao, me te kore e hiahiatia he hāora parakore teitei.
2. Parakore waenga (93%~95%):E whakamahia whānuitia ana i roto i te whakahāngaitanga hāora i roto i ngā mahi ahuwhenua ika, te whakahāngaitanga o te maimoatanga wai para, me ētahi tauhohenga whakahāngaitanga matū iti. He rawaka tēnei parakore mō ngā tukanga ā-hauora koiora, ngā tukanga whakahāngaitanga whānui rānei, e tuku ana i te utu tino whai hua.
3. Teitei o te parakore (≥99.2% – 99.6%):Ko te paerewa taumata tuatahi o te ahumahi, he pai mō te whakarewa me te tapahi i te konganuku, te hanga maitai whakarewa (pēnei i te pupuhi hāora kaitahuri), te hanga matū (pēnei i te waikura ethylene), me ētahi atu tukanga e hiahia ana ki ngā tauhohenga waikura kaha, e hiahia ana rānei kia tiakina mai i ngā poke.
4. Tino parakore (≥99.9%):E whakamahia ana i roto i te hanga haurua-haurua, te hanga muka whatu, ngā pūwero rererangi, me ngā matū pai motuhake. He tino tairongo ēnei āhuatanga ki ngā poke pēnei i te makuku me ngā hauwaiwai, me purenga hohonu.
Ngā Whakatūpato Matua:
1. Āraia rawatia te whakaranu: Tērā pea he iti noa te hauota waro, te hauhā waro, te acetylene, me te hinu kei roto i te hāora ahumahi, engari kaua rawa e whakamahia mō te manawa hauora, ki te kore ka pāngia e te riri o te pukahukahu, ka paitini, ka puta rānei te pupuhi o te pukahukahu.
2. Mā te tukanga e whakatau te parakore: Mā te wehenga hau cryogenic ka taea te whakatutuki i te parakore teitei (≥99.5%), ko te mimiti pēhanga (PSA) ka puta he parakore 90%-95%, ā, ko te wehenga kiriuhi te mea iti rawa te parakore (30%-50%). Me ōrite te kōwhiringa ki ngā whakaritenga takirua o te parakore me te rahinga hau mō te horopaki motuhake.
3. Ngā Rerekētanga Paerewa: E ai ki te paerewa ā-motu GB/T 3863 me ≥99.5% te taumata hāora ahumahi I, ā, me ≥99.2% te taumata II. I roto i ngā mahi whaihua, ki te kore he here motuhake mō ngā poke o te tukanga, tata ki te 93% e ranea ana mō te nuinga o ngā hiahia tahu me te whakatipu ika. Kāore he take ki te whai matapo i te parakore teitei hei penapena utu.
E toru ngā whakaaro hē e whakamahia pinepinetia ana mō te kōwhiringa ahumahi:
Whakaaro Hē 1: Ko te tikanga he pai ake ngā hua whakaputa, he nui ake te parakore o te hāora. Pono: Ko ia pikinga 1% o te parakore ka nui ake te kaha o te whakamahi hiko o te kaihanga hāora. He rawaka te 93% hāora mō ngā tukanga tuku iho i roto i ngā rauemi hanga, te maimoatanga wai para, me ngā pākahiko lithium. Mā te whiriwhiri matapo i te 99.5% hāora parakore teitei ka nui ake ngā utu hiko mā te neke atu i te 30%.
Whakaaro Hē 2: Ka taea e ngā kaihanga hāora ahumahi te whakakapi i te hāora hauora. Te Pono: Ahakoa te 93% o te parakore, kāore i ngā kaihanga hāora ahumahi ngā taputapu horoi me te tātari hau hauora, ā, kei roto hoki ngā poke pērā i te makuku me te puehu. Kāore e whakaaetia kia whakamahia hei tuku hāora manawa tangata. He rerekē rawa ngā paerewa haumaru e rua.
Pūrākau 3: Me whai hāora parakore teitei ngā āhuatanga tautoko mura katoa. Pono: Mō ngā oumu me ngā poiha noa, he rawaka te whakanui i te hāora wehenga kiriuhi 25%-40%, he pai ake te utu i ngā kaihanga hāora tātari ngota. Ko te whiriwhiri i te tauira tika mō ō hiahia motuhake te mea nui ki te whakaiti i te utu.
Whakarāpopototanga:Ko te mātāpono matua mō te whiriwhiri i ngā kaihanga hāora ahumahi ko: te mea tino pai mō ngā āhuatanga mahi, ehara i te mea ko te teitei ake o te parakore. Hei tautoko i te mura taketake, he pai te whakarei ake i te hāora wehenga kiriuhi; mō te whakaputanga ahumahi whānui, e taunakihia ana te 93% o ngā kaihanga hāora PSA paerewa; ko ngā tukanga tino tika anake e hiahia ana ki te hāora tino parakore o te 99.5% neke atu rānei. I mua i te hoko i ngā kaihanga hāora, me tautuhi mārama e ngā kamupene ā rātou whakaritenga mō te parakore o te hau tukanga me te tere rere kia tino tutuki ai te whakaputanga haumaru me te penapena pūngao.
