Kunzwisisa Kubvisa Mvura Yegungwa——Sea Water Reverse Osmosis Membrane

Parizvino, kubviswa kwemvura yegungwa kunonyanya kushandiswa nenzira mbiri dzehunyanzvi, dzinoti, membrane desalination process yakavakirwa pa reverse osmosis (RO) uye thermal desalination process yakavakirwa pa Multistage Flashing System (MSF) uye Multiple Effect Distillation (MED):

1. Reverse osmosis (RO): Iko kushandiswa kwe reverse osmosis membrane, pasi pekuita kwekumanikidzwa kwepamusoro, kuburikidza nekuongorora mhedzisiro ye membrane aperture, munyu uye kusvibiswa mumvura yegungwa zvakaparadzaniswa kuti vawane mvura yakachena.

2. Multi-stage flash evaporation: mvura yegungwa inopenya pasi pezvinetso zvakasiyana-siyana, uye mhute yemvura uye mvura yemvura inoparadzaniswa nekudzora kuchinja kwekumanikidza kuti uwane chinangwa chekubvisa munyu.

3. Multi-effect evaporation: Kushandiswa kwema-multi-stage evaporator, mvura yegungwa zvishoma nezvishoma inopisa evaporator, imwe neimwe nhanho ye evaporator inoshandisa mhepo muchikamu chekare cheevaporator kupisa, nekudaro kuchengetedza simba.

Reverse osmosis (RO) tekinoroji inoshandiswa zvakanyanya mukubvisa salination zvidyarwa. Reverse osmosis membrane ndeye yakakosha membrane filtration tekinoroji, nekushandisa yakanyanya kudzvanywa kumvura yegungwa nekumanikidza membrane, kuitira kuparadzanisa munyu, tupukanana, organic zvinhu uye kumwe kusvibiswa, kuwana mvura yakachena.

Zvikonzero nei reverse osmosis tekinoroji ichishandiswa zvakanyanya muzvirimwa zve desalination zvinosanganisira:

1. Kuita kwakanaka: Iyo reverse osmosis membrane ine yakakwira munyu impedance uye yakakwira flux, iyo inogona kunyatso bvisa munyu uye tsvina mumvura yegungwa uye kuwana yemhando yepamusoro mvura yakachena.

2. Kuchengetedza magetsi: Kuenzaniswa nemaitiro echinyakare ekubvisa salination senge pyrolysis distillation, reverse osmosis tekinoroji inoda kuderera kwesimba rekushandisa. Mune membrane yekuparadzanisa maitiro, imwe chete yekumanikidza inogona kushandiswa kuti iwane kuparadzaniswa kwemunyu, pasina kudikanwa kwekushisa kwepamusoro uye kudzvinyirira kwakanyanya, nekudaro kuchengetedza simba.

3. Sustainability: Reverse osmosis tekinoroji inokodzera mapurojekiti ekubvisa salination eese saizi, kubva kudiki desalination zvidyarwa kuenda kune hombe desalination zvidyarwa, kuti uwane inoenderera mvura. Panguva imwecheteyo, reverse osmosis membranes inogona kusanganiswa uye kugadziriswa kuti ienderane kune akasiyana emvura mhando uye kurapwa zvinodiwa.

4. Economy: Kunyangwe iyo yekutanga investimendi yereverse osmosis tekinoroji yakakwira, mutengo wayo unoderedzwa zvishoma nezvishoma nekuvandudzwa kwehunyanzvi uye nekuvandudzwa kwechiyero chekuita. Panguva imwecheteyo, nekuda kwekushanda kwepamusoro uye kuderera kwesimba rekushandisa maitiro ereverse osmosis tekinoroji, mari yekushandisa uye yekugadzirisa inogona kudzikiswa uye mabhenefiti ehupfumi anogona kuvandudzwa.

Tekinoroji yekuchenesa mvura yemugungwa yakakosha zvikuru mukugadzirisa dambudziko rekushaikwa kwemvura uye kusangana nezvinodiwa nevanhu vemvura, uye inoshandiswa zvakanyanya mukubvisa salination zvidyarwa, ngarava dzinofamba mugungwa, Marine science research nedzimwe ndima. Nekudaro, tekinoroji yedesalination inotarisanawo nematambudziko akadai sekushandisa simba, kusvibiswa kwe membrane uye kurapwa kwemvura yetsvina, izvo zvinoda kuenderera mberi kwehunyanzvi hwekuvandudza tekinoroji uye kuvandudzwa.

Mvura yegungwa desalination membrane imhando ye membrane zvinhu zvinoshandiswa mu membrane yekuparadzanisa tekinoroji yemvura yegungwa desalination process. Desalination membranes inonyanya kushandiswa mune reverse osmosis (RO) membrane masisitimu.

Mvura yegungwa desalination membrane inowanzogadzirwa nezvinhu zvepolymer senge polyether ester (PE) kana polyether ether ketone (PEEK), iyo ine hunhu hwekukwirisa munyu impedance, yakakwira flux uye kusagadzikana kwekuora. Chimiro chemembra chinowanzova chitete chine porous membrane, chinoparadzanisa munyu uye tsvina kuburikidza ne micropores mu membrane. Saizi yepore ye desalination membrane kazhinji iri pakati pe 0.1-0.0001 micron, iyo inogona kudzivirira nenzira yemunyu uye mamwe masolutes, kuitira kuti mvura yakachena ipfuure nekuzadzisa chinangwa chekubvisa mvura yegungwa.

Desalination membrane inoita basa rakakosha mukubvisa salination engineering. Iine zvakanakira kushanda kwepamusoro, kuchengetedza simba uye kuchengetedzwa kwezvakatipoteredza, izvo zvinogona kugadzirisa dambudziko rekushayikwa kwemvura uye kupa chitubu chemvura yakavimbika. Parizvino, desalination membrane tekinoroji yave imwe yenzira dzinoshandiswa zvakanyanya pasi rose.

Desalination membranes ine zvinotevera zvakanakira pane dzimwe nzira dzekubvisa salination:

1. Kuita kwakanaka: Mvura yegungwa desalination membrane ine yakakwira munyu impedance, yakakwira flux uye inobudirira kupatsanura kugona, iyo inogona kunyatso bvisa munyu uye tsvina mumvura yegungwa uye kuwana yemhando yepamusoro mvura yakachena.

2. Kuchengetedza magetsi: Kuenzaniswa nemaitiro echinyakare ekubvisa munyu senge pyrolysis distillation, desalination membrane inoda kuderera kwesimba rekushandisa. Mune membrane yekuparadzanisa maitiro, imwe chete yekumanikidza inogona kushandiswa kuti iwane kuparadzaniswa kwemunyu, pasina kudikanwa kwekushisa kwepamusoro uye kudzvinyirira kwakanyanya, nekudaro kuchengetedza simba.

3. Kuchengetedza kwezvakatipoteredza: Kuenzaniswa nedzimwe nzira, desalination membrane haidi kushandisa makemikari ejenti kana additives kudzivirira kusvibiswa kune nharaunda. Panguva imwecheteyo, hapana mvura yakasvibiswa inogadzirwa panguva yekuparadzanisa membrane, iyo inoderedza kusvibiswa kwemvura.

4. Sustainability: desalination membrane tekinoroji inogona kuchinjirwa kune akasiyana maapplication anodiwa kuburikidza neakasiyana membrane nzira dzekuparadzanisa dzakadai sereverse osmosis uye nanofiltration. Uku kuchinjika kunoita kuti tekinoroji yemembrane ikwane kune ese saizi yemapurojekiti ekubvisa salination, kubva kudiki desalination unit kusvika kune hombe desalination zvidyarwa, zvichiita kuti mvura irambe iripo.

5. Economy: Kunyangwe iyo yekutanga kudyara kwemvura yegungwa desalination membrane yakakwira, mutengo wayo unodzikiswa zvishoma nezvishoma nekuvandudzwa kwetekinoroji uye nekuvandudzwa kwechiyero chekuita. Panguva imwecheteyo, nekuda kwekushanda kwepamusoro uye kuderera kwesimba rekushandisa maitiro emvura yegungwa desalination membrane, kushanda uye kugadzirisa mari kunogona kuderedzwa uye hupfumi hwehupfumi hunogona kuvandudzwa.

Hupenyu hwesevhisi ye desalination membrane hunoenderana nemhando dzakasiyana siyana, kusanganisira kunaka kwe membrane zvinhu, mamiriro ekushandiswa kwe membrane, kushanda uye kugadzirisa. Kazhinji, hupenyu hwekugadzira hwema membranes emunyu hunowanzo pakati pe5 ne10 makore.

Izvi zvinotevera zvimwe zvezvinhu zvakakosha zvinokanganisa hupenyu hwesevhisi ye desalination membranes:

1. Membrane material quality: Hunhu uye kugadzikana kwe membrane zvinhu zvine chekuita kwakakosha pahupenyu hwebasa re membrane. Yepamusoro-mhando membrane zvinhu zvine yakakwira munyu kuramba uye kusagadzikana kwekuora, uye inogona kuchengetedza yakagadzikana yekuparadzanisa kuita mukushandiswa kwenguva refu.

2. Mamiriro ekushanda: Mamiriro ekushanda anewo simba guru pahupenyu hwebasa re membrane. Kusanganisira kunaka kwemvura, tembiricha, kudzvanywa uye zvimwe zvinhu. Kunyanya tembiricha, kudzvanywa, kana makemikari ari mumhando yemvura anogona kuita kuti membrane ichembe, itsemuka, kana kuvharika, nekudaro ichipfupisa hupenyu hwesevhisi ye membrane.

3. Maintenance: Nguva dzose membrane yekuchenesa uye kugadzirisa kwakakosha kuti uwedzere hupenyu hwebasa re membrane. Kuchenesa nguva dzose kunogona kubvisa kusvibiswa uye munyu kubva pamusoro pefirimu, kuchengetedza kubuda uye kushanda kwefirimu. Panguva imwecheteyo, kugadzirisa nguva dzose kunogonawo kuona uye kubata nekukuvara kana kukundikana kwe membrane munguva yekudzivirira imwe kukuvara.
