Sistimi ea ho hlaphoheloa ea NMP ke eng tlhahisong ea betri ea lithium?
Keselelekela
Tlhahisong ea betri ea lithium, NMP e sebelisoa haholo ho penteng ea electrode. Nakong ea ho omisa, ho hlahisoa likhase tse ngata tsa mosi o nang le NMP. Ntle le ho hlaphoheloa hantle, bahlahisi ba ka tobana le tahlehelo ea solvent, tšebeliso e phahameng ea matla, le khatello ea ho latela VOC.
Ka lebaka lena, litsamaiso tsa ho hlaphoheloa ha NMP li fetohile lisebelisoa tsa bohlokoa lifemeng tsa betri tsa sejoale-joale.
Sistimi ea ho hlaphoheloa ea NMP ke eng?
Sistimi ea ho hlaphoheloa ea NMP e hapa mouoane oa solvent ho tsoa khaseng ea mosi e koahelang ebe e e fetola mokelikeli o ka sebelisoang hape ka ho hlaphoheloa mocheso, ho kolobisoa ha metsi le karohano ea khase le mokelikeli.
Morero oa eona o ka sehloohong ke ho fokotsa tahlehelo ea solvent, litšenyehelo tse tlase tsa matla, le ho tšehetsa tlhahiso e hloekileng.
Hobaneng e le ea bohlokoa?
Litsi tsa betri li hloka ho laola lintlha tse 'ne ka nako e le' ngoe: tšebeliso ea li-solvent, mesi ea VOC, tlhoko ea matla a ho omisa, le tlhahiso e tsitsitseng ea tekanyo e kholo.
Mekhoa e meng e tloaelehileng e ka fihlela litlhoko tsa mantlha tsa ho hlaphoheloa, empa katleho ea tsona ea ho hlaphoheloa mocheso hangata e ka ba liphesente tse 60-75 tlas'a meralo e tloaelehileng. Bakeng sa merero e nang le litlhoko tse phahameng tsa katleho le botsitso, hangata ho nahanoa ka litharollo tse tsoetseng pele kapa tse kopaneng tsa ho hlaphoheloa.
Sistimi e sebetsa joang?
Ho hlaphoheloa ha mocheso:
- Mocheso o fapanyetsana moea o futhumatsang le o kgutlisang ho fokotsa tshebediso ya matla. Meralong e tlwaelehileng, tshebetso e itshetlehile ka sebopeho sa sistimi le maemo a tshebetso, mme bokgoni bo ka fapana ho pholletsa le diporojeke.
Ho kolobisa:
- Kamora ho hlaphoheloa mochesong, mouoane oa NMP o pholisoa hore e be mokelikeli. Ha ho bapisoa le meaho e bonolo ea ho pholisa, ho kolobisoa ha mekhahlelo e mengata hangata ho fana ka ts'ebetso e tsitsitseng haholoanyane ea ho hlaphoheloa tlas'a tlhahiso e tsoelang pele.
Karohano ea khase le mokelikeli:
- Karohano ea khase le mokelikeli e sebelisetsoa ho fokotsa ho kenngoa ha metsi le ho ntlafatsa boleng ba ho hlaphoheloa. Litsamaiso tsa motheo li ka sebelisa meaho e bonolo e qhaqhoang, e leng se ka lebisang maemong a sa tsitsang a ho khutla ha moea.
Kalafo ea VOC:
- Khase ea mohatla e phekoloa ho fihlela maemo a tikoloho. Ho latela litlhoko tsa projeke, litsamaiso tsa adsorption rotor kapa litora tsa absorption hangata li kenyelelitsoe ts'ebetsong ea ho hlaphoheloa.
Maemo a kopo
Mekhoa ea ho hlaphoheloa ea NMP e sebelisoa haholo mefuteng ea libeteri tsa EV, lifemeng tsa libeteri tsa polokelo ea matla, le mererong e meng ea ho koahela ka litlhoko tse thata tsa tikoloho le taolo ea litšenyehelo.
Li bohlokoa haholo bakeng sa mela e mahareng le e meholo ea ho koahela e hlokang ho hlaphoheloa ha solvent e tsitsitseng le litšenyehelo tse laoloang tsa ts'ebetso.
Bahlahisi ba libeteri ba mehleng ena ba ela hloko haholoanyane litharollo tse kopaneng tsa ho hlaphoheloa ho fapana le kalafo ea motheo ea mosi feela.
Mohlala, sistimi ea ho hlaphoheloa ea NMP ea Pengjin e kopanya ho hlaphoheloa ha mocheso, ho koaheloa ha mocheso ka mekhahlelo e mengata, le kalafo ea khase ea mohatla moralong o kopaneng. Sistimi ea eona ea cathode e sebelisa 90-95% ea ho khutlisa moea le phapanyetsano ea mocheso ho fihlela ho 85%. Tharollong ea eona e thehiloeng ho rotor, mesi e ka laoloa ho 5-50 mg/Nm³, ka data ea laboratori e tlase ho 1 mg/Nm³, ha tharollo ea eona e thehiloeng ho tora e ka fihlela 15-50 mg/Nm³ tlas'a ts'ebetso e tsitsitseng.
Sistimi ea ho hlaphoheloa ha NMP ha se sesebelisoa sa tikoloho feela, empa hape ke sesebelisoa se sebetsang sa ho fokotsa tahlehelo ea solvent le litšenyehelo tsa ts'ebetso.
Mekhoa ea motheo e ka lumellana le merero e menyenyane, athe litharollo tse kopantsoeng hangata li loketse haholoanyane mela e meholo ea betri ea lithium e nang le litlhoko tse phahameng tsa ho boloka matla, botsitso ba ho hlaphoheloa le taolo ea mosi.
