Kumvetsetsa Kuchotsa Madzi a M'nyanja——Sea Water Reverse Osmosis Membrane

Pakali pano, kuchotsa mchere m'madzi a m'nyanja kumayendetsedwa ndi njira ziwiri zaukadaulo, zomwe ndi njira yochotsa mchere m'madzi. reverse osmosis (RO) ndi matenthedwe desalination ndondomeko zochokera Multistage Flashing System (MSF) ndi Multiple Effect Distillation (MED):

1. Reverse osmosis (RO): Kugwiritsiridwa ntchito kwa nembanemba ya reverse osmosis, pansi pa kupanikizika kwakukulu, kupyolera mu kuwunika kwa kabowo ka membrane, mchere ndi zonyansa m'madzi a m'nyanja zimalekanitsidwa kuti mupeze madzi abwino.

2. Multi-stage flash flash evaporation: madzi a m'nyanja amang'anima pansi pa zovuta zosiyanasiyana, ndipo nthunzi yamadzi ndi madzi amadzimadzi amalekanitsidwa ndi kulamulira kusintha kwa kuthamanga kuti akwaniritse cholinga chochotsa mchere.

3. Multi-effect evaporation: Ntchito Mipikisano siteji evaporator, madzi a m'nyanja pang'onopang'ono mkangano evaporator, gawo lililonse la evaporator ntchito nthunzi mu yapita siteji ya evaporator kutentha, potero kupulumutsa mphamvu.

Tekinoloje ya Reverse Osmosis (RO) imagwiritsidwa ntchito kwambiri pochotsa mchere. Reverse osmosis nembanemba ndi luso lapadera la kusefera kwa nembanemba, pogwiritsa ntchito kuthamanga kwambiri kumadzi a m'nyanja pokakamiza nembanemba, kuti alekanitse mchere, tizilombo tating'onoting'ono, zinthu zachilengedwe ndi zonyansa zina, kuti tipeze madzi abwino.

Zifukwa zomwe ukadaulo wa reverse osmosis umagwiritsidwa ntchito kwambiri muzomera za desalination ndi monga:

1. Kuchita bwino: Reverse osmosis nembanemba imakhala ndi mchere wambiri komanso kuthamanga kwambiri, komwe kumatha kuchotsa mchere ndi zonyansa m'madzi am'nyanja ndikupeza madzi abwino kwambiri.

2. Kupulumutsa mphamvu: Poyerekeza ndi njira zachikhalidwe zochotsera mchere monga pyrolysis distillation, ukadaulo wa reverse osmosis umafunika kugwiritsa ntchito mphamvu pang'ono. Mu njira yolekanitsa nembanemba, kukakamizidwa kokhako kungagwiritsidwe ntchito kuti akwaniritse kulekanitsa mchere, popanda kufunikira kwa kutentha kwakukulu ndi kupanikizika kwakukulu, motero kupulumutsa mphamvu.

3. Kukhazikika: Ukadaulo wa Reverse osmosis ndioyenera pulojekiti yochotsa mchere wamchere wamitundu yonse, kuyambira pamitengo yaying'ono yochotsa mchere wamchere kupita kumitengo yayikulu yochotsa mchere, kuti mupeze madzi okhazikika. Nthawi yomweyo, ma membrane am'mbuyo a osmosis amatha kuphatikizidwa ndikusinthidwa kuti agwirizane ndi mitundu yosiyanasiyana yamadzi komanso zofunikira zamankhwala.

4. Chuma: Ngakhale kuti ndalama zoyamba zaukadaulo wa reverse osmosis ndizokwera, mtengo wake umachepetsedwa pang'onopang'ono ndi chitukuko chaukadaulo komanso kusintha kwamphamvu. Nthawi yomweyo, chifukwa chakuchita bwino kwambiri komanso kugwiritsa ntchito mphamvu pang'ono kwaukadaulo wa reverse osmosis, ndalama zogwirira ntchito ndi kukonza zitha kuchepetsedwa ndipo phindu lazachuma litha kupitilizidwa.

Ukadaulo wochotsa mchere m'madzi a m'nyanja ndi wofunikira kwambiri pakuthana ndi vuto la kusowa kwa madzi ndikukwaniritsa kufunikira kwa madzi a anthu, ndipo umagwiritsidwa ntchito kwambiri m'mafakitale ochotsa mchere, zombo zapanyanja, kafukufuku wasayansi wapanyanja ndi zina. Komabe, ukadaulo wa desalination umakumananso ndi zovuta monga kugwiritsa ntchito mphamvu, kuyipitsidwa kwa membrane ndi kuyeretsa madzi oyipa, zomwe zimafunikira ukadaulo waukadaulo ndikuwongolera mosalekeza.

M'madzi a m'nyanja desalination nembanemba ndi mtundu wa zinthu nembanemba ntchito nembanemba kulekana ukadaulo wa madzi a m'nyanja njira desalination. Ma membrane a desalination amagwiritsidwa ntchito makamaka pamakina a reverse osmosis (RO).

Madzi a m'nyanja amadzimadzi amadzimadzi nthawi zambiri amapangidwa ndi zinthu za polima monga polyether ester (PE) kapena polyether ether ketone (PEEK), yomwe ili ndi mawonekedwe oletsa mchere wambiri, kuthamanga kwambiri komanso kukana dzimbiri. Kapangidwe ka nembanemba kawirikawiri woonda porous nembanemba, amene amalekanitsa mchere ndi zosafunika kudzera micropores mu nembanemba. Kukula kwa pore kwa nembanemba ya desalination nthawi zambiri kumakhala pakati pa 0.1-0.0001 micron, yomwe ingalepheretse kupita kwa mchere ndi zosungunulira zina, kuti madzi abwino adutse ndikukwaniritsa cholinga chochotsa mchere m'madzi am'nyanja.

Desalination nembanemba imagwira ntchito yofunika kwambiri pakuchotsa mchere. Lili ndi ubwino wapamwamba kwambiri, kupulumutsa mphamvu ndi kuteteza chilengedwe, zomwe zingathe kuthetsa vuto la kusowa kwa madzi ndikupereka madzi odalirika. Pakali pano, ukadaulo wa desalination membrane wakhala imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi pochotsa mchere.

Ma nembanemba a desalination ali ndi zabwino izi kuposa njira zina zochotsera mchere:

1. Kuchita bwino: Madzi a m'nyanja amadzimadzi amadzimadzi amakhala ndi vuto la mchere wambiri, kuthamanga kwambiri komanso kulekanitsa bwino, komwe kumatha kuchotsa mchere ndi zonyansa m'madzi am'nyanja ndikupeza madzi abwino kwambiri.

2. Kupulumutsa mphamvu: Poyerekeza ndi njira zachikhalidwe zochotsera mchere monga pyrolysis distillation, nembanemba ya desalination imafuna kugwiritsa ntchito mphamvu pang'ono. Mu njira yolekanitsa nembanemba, kukakamizidwa kokhako kungagwiritsidwe ntchito kuti akwaniritse kulekanitsa mchere, popanda kufunikira kwa kutentha kwakukulu ndi kupanikizika kwakukulu, motero kupulumutsa mphamvu.

3. Kuteteza chilengedwe: Poyerekeza ndi njira zina, desalination nembanemba safunikira kugwiritsa ntchito mankhwala kapena zowonjezera kuti apewe kuipitsidwa kwa chilengedwe. Panthawi imodzimodziyo, palibe madzi owonongeka omwe amapangidwa panthawi yolekanitsa nembanemba, zomwe zimachepetsa kutaya kwa madzi.

4. Kukhazikika: ukadaulo wa desalination membrane ukhoza kusinthidwa kuti ugwirizane ndi zosowa zosiyanasiyana zogwiritsira ntchito kudzera munjira zosiyanasiyana zolekanitsa nembanemba monga reverse osmosis ndi nanofiltration. Kusinthasintha kumeneku kumapangitsa ukadaulo wa nembanemba kukhala wokwanira pama projekiti amitundu yonse yochotsa mchere, kuyambira magawo ang'onoang'ono ochotsa mchere mpaka kumitengo yayikulu yochotsa mchere, zomwe zimapangitsa kuti madzi azikhala okhazikika.

5. Chuma: Ngakhale kuti ndalama zoyambira zochotsa madzi am'nyanja zam'madzi ndizokwera, mtengo wake umachepetsedwa pang'onopang'ono ndi chitukuko chaukadaulo komanso kuwongolera sikelo. Nthawi yomweyo, chifukwa chakuchita bwino kwambiri komanso kugwiritsa ntchito mphamvu pang'ono kwa nembanemba yochotsa madzi am'nyanja, ndalama zogwirira ntchito ndi kukonza zitha kuchepetsedwa ndipo phindu lazachuma likhoza kuwongolera.

Moyo wautumiki wa nembanemba ya desalination umadalira zinthu zosiyanasiyana, kuphatikiza mtundu wa zinthu za nembanemba, momwe amagwiritsidwira ntchito nembanemba, kugwira ntchito ndi kukonza. Nthawi zambiri, moyo wa mapangidwe a nembanemba yochotsa mchere nthawi zambiri umakhala pakati pa zaka 5 ndi 10.

Izi ndi zina mwazinthu zazikulu zomwe zimakhudza moyo wautumiki wa nembanemba za desalination:

1. Mamembala azinthu: Ubwino ndi kukhazikika kwa zinthu za nembanemba zimakhudza kwambiri moyo wautumiki wa nembanemba. Zida za membrane zapamwamba zimakhala ndi kukana kwa mchere wambiri komanso kukana kwa dzimbiri, ndipo zimatha kusunga magwiridwe antchito olekanitsa pakagwiritsidwa ntchito nthawi yayitali.

2. Kagwiritsidwe ntchito: Mikhalidwe yogwirira ntchito imakhudzanso kwambiri moyo wautumiki wa nembanemba. Kuphatikizapo ubwino wa madzi, kutentha, kuthamanga ndi zina. Kutentha kwambiri, kupanikizika, kapena mankhwala omwe ali mumtundu wamadzi amatha kupangitsa kuti nembanembayo ikalamba, kusweka, kapena kutsekeka, potero kufupikitsa moyo wautumiki wa nembanembayo.

3. Kusamalira: Kuyeretsa ndi kukonza kwa membrane nthawi zonse ndikofunikira kuti muwonjezere moyo wautumiki wa nembanemba. Kuyeretsa nthawi zonse kumatha kuchotsa zonyansa ndi mchere kuchokera pamwamba pa filimuyo, kusunga kusinthasintha ndi machitidwe a filimuyo. Panthawi imodzimodziyo, kukonza nthawi zonse kungathenso kuzindikira ndi kuthana ndi kuwonongeka kapena kulephera kwa nembanemba mu nthawi kuti zisawonongeke.
