Pab neeg tshawb fawb los ntawm Angel Group Central Research Institute thiab State Key Joint Laboratory of Environment Simulation thiab Pollution Control ntawm Tsinghua University tau koom tes luam tawm ib daim ntawv nyob rau hauv Desalination, ib tug interdisciplinary journal luam tawm cov ntaub ntawv zoo ntawm desalination cov ntaub ntawv, txheej txheem thiab lwm yam technologies, ib tug ntawm cov sab saum toj peb cov ntawv xov xwm kev kawm hauv kev lag luam kho dej.
Title:Kev ua tau zoo ntawm Kauv-qhov txhab Rov qab Osmosis Membrane Elements nrog Novel Diagonal-flow Feed Channel
DOI: 10.1016/j.desal.2021.115447
Abstract
Kauv-qhov txhab rov qab osmosis membrane cov ntsiab lus tau siv dav hauv kev lim dej hauv tsev uas feem ntau xav tau cov dej rov qab siab.Membrane scaling tseem yog ib qho teeb meem cuam tshuam uas yuav ua rau tsis zoo rau kev ua haujlwm ntawm daim nyias nyias.Hauv txoj kev tshawb no, peb tau tsim ib qho tshiab pub channel nrog kab pheeb ces kaum ntws, uas cov kev ua yeeb yam tau tshuaj xyuas los ntawm cov kev sim pom ntawm cov ntaub ntawv tiag tiag thiab cov kev cuam tshuam ntawm kev teeb tsa channel tau txheeb xyuas los ntawm kev sib txuas ntawm kev sib txuas ntawm cov dej sib xyaw ua ke nrog cov lus teb saum npoo txheej txheem.Cov txiaj ntsig tau pom tias cov khoom siv membrane nrog cov kab pheeb ces kaum-kho tshiab tau nthuav tawm cov dej ntws ntau dua nrog rau qis qis qis thiab kev tsis lees ntsev ntau dua li cov lus pom zoo nrog axial flow direction.Kev hloov pauv ntawm cov dej ntws ntws tuaj yeem ua rau muaj txiaj ntsig zoo rau qhov nruab nrab ntawm kev sib tw khiav hauv cov channel, yog li txhim kho huab hwm coj hloov pauv thiab txo cov concentration polarization.Rau lub hom phiaj dej rov qab ntawm 75% thiab cov dej ntws ntawm ~ 45 L / (m2·h), qhov kev pom zoo hais txog qhov sib piv ntawm qhov dav thiab qhov nqaim qhib ntawm qhov nkag / qhov hluav taws xob ntawm kab pheeb ces kaum-flow feed channel yog qhia nyob rau hauv 20-43% thiab 5-10%, feem.Cov kab pheeb ces kaum-ntws pub channel muaj kev cia siab rau daim ntawv thov kev cia siab rau kev tswj cov txheej txheem membrane.
Qhov tseem ceeb
• Novel diagonal-flow feed channel tau tsim los rau RO membrane ntsiab.
• Kev ua tau zoo ntawm cov txheej membrane tau txhim kho nrog cov flux ntau dua thiab kev tsis kam ntsev.
• Diagonal-flow feed channel tuaj yeem txhawb kev hloov pauv loj thiab txo cov txheej txheem membrane.
• Diagonal-flow feed channel tau cog lus thaum cov dej ntws tawm thiab cov nqi rov qab siab dua.
Kev tshaj tawm cov txiaj ntsig kev tshawb fawb txog kev siv tshuab ua haujlwm ntev ntev hauv cov ntawv xov xwm thoob ntiaj teb sawv cev rau kev ua tiav ntawm kev siv thev naus laus zis thiab kev tshawb fawb ntawm cov teb tshiab, yog li tsim Angel lub hauv paus kev sib tw kom zoo dua.Nyob rau hauv lub neej yav tom ntej, Angel Group Central Research Institute yuav txuas ntxiv muab kev tsav tsheb mus sij hawm ntev nrog cov thev naus laus zis tshiab, mob siab rau nrhiav cov thev naus laus zis tshiab rau kev ntes, thiab tuav lub lag luam siab rau cov khoom lag luam tshiab nrog cov thev naus laus zis qub.
