HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Mpweya woyeretsedwa kwambiri umagwiritsidwa ntchito kwambiri m'magawo azachipatala, mafakitale, ndi kafukufuku wasayansi. Kukula kosalekeza kwa ukadaulo wake wopanga kwapangitsa kuti pakhale zofunikira zambiri kuti mpweya ukhale woyera komanso wothandiza popanga. Nkhaniyi ipereka njira zingapo zodziwika bwino zopangira mpweya woyeretsedwa kwambiri, kusanthula mfundo zogwirira ntchito, zabwino ndi zoyipa zake, ndi zochitika zomwe zingagwiritsidwe ntchito.

1. Njira Yolekanitsira Mpweya

Njira yolekanitsa mpweya ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri popanga mpweya wabwino kwambiri. Mfundo yake yaikulu ndikulekanitsa zigawo zosiyanasiyana mumlengalenga pamalo osiyanasiyana owira pogwiritsa ntchito ukadaulo woziziritsa wa cryogenic.

1.1 Njira Yolekanitsira Mpweya Wozizira Kwambiri

Njira yolekanitsa mpweya wozizira kwambiri ndi ukadaulo wamakono wopanga mpweya wa okosijeni. Njirayi imagwiritsa ntchito kusiyana kwa kutentha kwa zinthu zosiyanasiyana mumlengalenga pansi pa kupsinjika ndi kutentha kosiyanasiyana. Kudzera m'magawo angapo a kupsinjika, kuzizira, ndi kusungunuka, mpweya wa okosijeni, nayitrogeni, ndi mpweya wina umalekanitsidwa ndi mpweya. Chipangizo cholekanitsa mpweya wozizira kwambiri chimagwiritsa ntchito nsanja zoyeretsera zokhala ndi magawo angapo kuti pamapeto pake zipeze mpweya woyera kwambiri wokhala ndi chiyero choposa 99.5%.

Ubwino wa njira yolekanitsira mpweya wozizira kwambiri ndi wakuti imatha kupanga mpweya woyera kwambiri pamlingo waukulu komanso mosalekeza, ndipo ndi yoyenera kugwiritsidwa ntchito m'mafakitale omwe amafunikira mpweya wambiri, monga kusungunula zitsulo ndi njira zopangira mankhwala. Zoyipa zake ndi zakuti ndalama zoyambira zimakhala zambiri, kugwiritsa ntchito mphamvu zambiri, komanso zofunikira pakukonza ndi kugwiritsa ntchito zida ndizokwera.

1.2 Njira Yopatulira Kukanikiza ndi Kukulitsa

Njira yolekanitsira mpweya wozizira kwambiri ndi njira yabwino yolekanitsira mpweya wozizira kwambiri. Mwa kukanikiza mpweya ndikuukulitsa mofulumira, mpweya umaziziritsidwa ndipo mpweya ndi zinthu zina zimalekanitsidwa. Njirayi ingathenso kupeza mpweya woyera kwambiri, koma poyerekeza ndi njira yachikhalidwe yolekanitsira mpweya wozizira kwambiri, kuchuluka kwa zida zake ndi kochepa ndipo ndikoyenera kupanga mpweya wozizira pang'ono.

2. Njira Yothira Madzi Othamanga (PSA)

Kuponderezedwa kwa Mpweya (PSA) ndi njira yomwe imagwiritsidwa ntchito kwambiri popanga mpweya wabwino kwambiri m'mafakitale. Mfundo ya PSA ndikugwiritsa ntchito mawonekedwe osankhidwa a okometsera mpweya (monga ma sieve a zeolite molecular) kuti apeze nayitrogeni ndi mpweya wabwino mumlengalenga. Pakapanikizika kosiyanasiyana, nayitrogeni imaponderezedwa ndikuchotsedwa motsatana, motero imapeza mpweya wabwino kwambiri.

Ubwino wa njira ya PSA ndikuti zida zake ndi zosavuta, kuyambitsa kwake kumakhala kofulumira, ndipo ndalama zogwirira ntchito ndizochepa. Sizimafuna njira yovuta yoziziritsira, motero imagwiritsidwa ntchito kwambiri pazida zazing'ono zopangira mpweya. Kuyera kwa mpweya wopangidwa ndi njira ya PSA nthawi zambiri kumakhala pakati pa 90% ndi 95%, koma kudzera mu kusintha koyenera, kuyera kumatha kuwonjezeredwa mpaka kupitirira 99%.

Komabe, kuipa kwa njira ya PSA ndikuti kupanga ndi kuyera kwa itooxygen kumachepa ndi magwiridwe antchito a adsorbent, ndipo kugwira ntchito bwino kwa dongosololi kumakhudzidwa ndi ukalamba wa adsorbent. Chifukwa chake, njira iyi ndi yoyenera kwambiri kwa mabizinesi kapena mabungwe azachipatala omwe alibe mpweya wokwanira.

Ndife opanga ndi kutumiza kunja kwa chipangizo cholekanitsa mpweya. Ngati mukufuna kudziwa zambiri za ife:
