Mutu:Kupititsa patsogolo Kuchita kwa Spiral-wound Reverse Osmosis Membrane Elements ndi Novel Diagonal-flow Feed Channel

Ndemanga
Zinthu za Spiral-wound reverse osmosis membrane zakhala zikugwiritsidwa ntchito kwambiri pakuyeretsa madzi am'nyumba zomwe nthawi zambiri zimafuna kuti madzi azibweza kwambiri.Kukula kwa ma membrane kumakhalabe chopinga chosatheka chomwe chingawononge magwiridwe antchito a membrane.Mu kafukufukuyu, tidapanga njira yodyetsera yomwe ili ndi njira yoyendera ma diagonal, yomwe machitidwewo adawunikidwa poyesa kusefera pa zinthu zenizeni za membrane ndipo zomwe zimakhudzidwa ndi kasinthidwe ka tchanelo zidawunikidwa kudzera pakuphatikiza mphamvu zamadzimadzi zoyeserera ndi njira yoyankhira pamwamba.Zotsatira zake zidawonetsa kuti gawo la nembanemba lomwe lili ndi njira zodyetserako za diagonal-flow feed likuwonetsa kuchulukira kwamadzi komanso kutsika kocheperako komanso kukana mchere wambiri kuposa wamba komwe kumayendera axial.Kusintha kwa kayendedwe ka madzi kungathe kuonjezera kuthamanga kwa kayendedwe ka madzi mu njirayo, motero kumapangitsa kuti anthu ambiri asamuke komanso kuchepetsa kugawanika kwa maganizo.Kuti madzi abwezeretsedwe ndi 75% ndi kutuluka kwa madzi kwa ~ 45 L/(m2·h), masinthidwe oyenera okhudzana ndi kuchuluka kwa m'lifupi mwake ndi mipata yopapatiza panjira yolowera / potulutsiramo ma diagonal-flow feed channels akulimbikitsidwa mkati mwa 20-43% ndi 5-10%, motero.Njira yodyetsera ya diagonal-flow feed ili ndi chiyembekezo chodalirika chogwiritsa ntchito kuwongolera ma membrane.
Mfundo zazikuluzikulu
• Novel diagonal-flow feed channel anapangidwira RO nembanemba zinthu.
• Kugwira ntchito kwa nembanemba kunalimbikitsidwa ndi kusinthasintha kwakukulu ndi kukana mchere.
• Diagonal-flow feed channel ikhoza kulimbikitsa kusamutsa anthu ambiri ndikuchepetsa kukweza kwa membrane.
• Njira ya chakudya cha diagonal-flow feed imapangitsa kuti madzi azituluka ndi kuchira kwambiri.

Kusindikizidwa kwa zotsatira za kafukufuku wokhudzana ndi ukadaulo wa membrane wokhalitsa m'manyuzipepala apamwamba padziko lonse lapansi kukuwonetsa kutsogola kwaukadaulo wakale komanso kuwunika kwatsopano, zomwe zimapangitsa kuti Angel akhale ndi mwayi wampikisano.M'tsogolomu, Angel Group Central Research Institute ipitiliza kupititsa patsogolo luso laukadaulo kwanthawi yayitali, kutsata mwamphamvu luso laukadaulo kuti lipezeke, ndikukhala pachimake pamsika wazinthu zatsopano ndi matekinoloje oyambilira.
