Abstract
Spiral-wound reverse osmosis membrane zvinhu zvakashandiswa zvakanyanya mukuchenesa mvura yemumba izvo zvinowanzoda mwero wepamusoro wekudzoreredza mvura.Membrane scaling inoramba iri chipingamupinyi chisingachinjiki chinozokanganisa kuita kwemembrane elements.Muchidzidzo ichi, takagadzira chiteshi chekudya chine diagonal kuyerera kwakananga, uko maitirwo akaongororwa nekusefa kuyedza pane chaiyo membrane zvinhu uye mabatiro ekugadziriswa kwechiteshi akaongororwa kuburikidza nekubatanidza computational fluid dynamics simulation nemhinduro yepamusoro nzira.Mhedzisiro yacho yakaratidza kuti membrane element ine novel diagonal-flow feed channels yairatidza kuyerera kwemvura yakakwira pamwe nekudzikira kwakadzikira uye kurambwa kwemunyu kwakakwira pane yakajairika ine axial kuyerera.Shanduko yenzira yekuyerera kwemvura inogona kuwedzera zvakanyanya avhareji yekuyambuka-kuyerera velocity muchiteshi, nekudaro kuwedzera kufambiswa kwevazhinji uye kuderedza concentration polarization.Kudzoreredza mvura inosvika makumi manomwe neshanu muzana uye kubuda kwemvura kwe ~ 45 L/(m2 · h), iyo yakakwana gadziriso maererano nehupamhi hwereshiyo yehupamhi uye yakamanikana painopinza/pakubuda kwediagonal-kuyerera kwekudya nzira inokurudzirwa mukati me 20-43% uye 5-10%, maererano.Iyo diagonal-yekuyerera feed chiteshi ine inovimbisa application tarisiro ye membrane kuyera kutonga.
Pfungwa huru
• Novel diagonal-flow feed channel yakagadzirirwa RO membrane zvinhu.
• Kuita kwemembrane element kwakawedzerwa nekukwira kwepamusoro uye kurambwa kwemunyu.
• Diagonal-flow feed channel inogona kukurudzira kutamisa vanhu vakawanda uye kuderedza membrane scaling.
• Diagonal-flow feed channel iri kuvimbisa kana mvura inoyerera uye chiyero chekudzorera chiri chakakwirira.
Kuburitswa kwemhedzisiro yekutsvagisa nezve inogara kwenguva refu membrane tekinoroji mumajenari epamusoro epasirese inomiririra budiriro mune yechinyakare tekinoroji uye kuongororwa kweminda mitsva, nekudaro kuvaka musimboti wekukwikwidza mukana weAngel.Mune ramangwana, Angel Group Central Research Institute icharamba ichipa iyo refu-refu dhiraivha nehunyanzvi hwekuita tekinoroji, kutsvaga zvine simba hunyanzvi hwekuita tekinoroji yekubata, uye kutora nzvimbo dzakakwirira dzemusika wekuvandudzwa kwechigadzirwa nehunyanzvi hwekutanga.
