Inqubo yokubuyisa i-sodium sulfate ekukhiqizweni kwebhethri le-lithium

Enqubweni yokuphinda usebenzise kabusha kwamabhethri we-ternary lithium namabhethri we-lithium iron phosphate, i-sulfuric acid kanye ne-caustic soda kuguqulwe ngokungafanele kusawoti we-sodium sulfate ngenxa yezidingo zobuchwepheshe ngenxa yezidingo zobuchwepheshe. Isixazululo esiluhlaza esiqukethe i-sodium sulfate ikakhulukazi sifaka ikhambi le-Lithium Sast System, ikhambi ngemuva kokukhishwa kwe-lithium iron phosphate, ikhambi ngemuva kokwelashwa kwe-lithium lithium ngosawoti we-lithium lithium nge Ukukhishwa kosawoti kwe-nickel-cobalt-manganelt-manganelt, ikhambi ngemuva kokuhlelwa kwe-nickel-cobalt-manganese, njll. Lezi zixazululo ziqondile noma zihlanjululwe ohlelweni lwe-mvr i-sodium sulfate. Inqubo yokukhiqiza eyinhloko imi ngalendlela elandelayo:

1. Hlanganisa uketshezi
I-Brinethate ye-Ternary nickel-cobalt ye-brine, i-tithium iron phosphate ngemuva kokuxazulula i-lithium, i-lithium iron phobate debolt manganel ukukhishwa kwama-sickel

2. Ukususa ukungcola nokucwengisisa
Ngemuva kokulungiswa kwesisombululo se-sodium sulfate by kewun alkali + sodium sulfide ukujula ukuze ususe izinsimbi ezisindayo (cindezela uchofoze inani elincane le-nickel ne-cobalt slag, buyela ukuze uphinde usebenzise kabusha), lungisa i-PH kuya ku-5 ~ 7; Ngemuva kokuhlaziywa kokufanelekile, kufakwa ithangi eliluhlaza okotshani, futhi ithangi eliluhlaza owuketshezi lidlala indima yokugcina nokulawula uketshezi oluhlaza ukuze ahlangane nokusebenza okuqhubekayo kwe-MVR Wastewater Evaporator. Ithangi eliluhlaza uketshezi lifakwe iphampu eluhlaza eluhlaza. Iphampu eluhlaza eluhlaza ihambisa ngokulinganayo isisombululo samanzi se-sodium sulfate sokulula kohlelo lokuhwamuka. I-valve yokulawula ngemuva kokuthi iphampu eluhlaza uketshezi ilungiswe ukuze ilondoloze ibhalansi phakathi kwenani lokuphakamisa loketshezi oluhlaza kanye nenani lokuhwamuka.

3. Isixazululo Sokubuyisa
I-sodium sulfate crystaydrate amakristalu akhiqizwe ngohlelo lwe-lithium usawoti angezwa emanzi ancibilikisiwe kanye namanzi okugeza ama-lithium aphansi ukuze akhishwe ethangini elihlukile le-sodium sulfate bese eligcinwa ngqo ohlelweni lwe-mvr.

I-4. I-MVR i-Ekfaping kanye ne-Crystallization of sodium sulfate solution
Isixazululo esinamanzi aqukethe i-sodium sulfate sishaywa yi-condensate prebeter bese singena egumbini lokuhwamuka kohlelo lwe-crystallization lwe-mvr. Uhlelo lwe-MVR EkAPoration luhlome nge-vertical Heat Exchanger ngemuva kokusakazwa okuphoqelekile ukujikeleza kwegazi. Ngaphansi kwesenzo sephampu yokujikeleza okuphoqelekile, uketshezi lwezinto ezibonakalayo lugeleza ekusakazweni kwegumbi lokuhwamuka - I-Exchanger Exchanger - I-Exchanger CalchAnger - I-Exchanger Consanger - Ukuhlukaniswa okuqinile kwegesi kufuthelwa egumbini lokushisa. I-slurry kasawoti ehlanganisiwe ithunyelwa ekukhishweni kosawoti yipompo yokukhipha ukuze igxile ukugxilisa nokuhlukaniswa, bese idedelwa ku-shrist kasawoti ukuze iqoqe futhi yahlukaniswa futhi yahlukaniswa, futhi ekugcineni yadedelwa e-centrifugal yokwehlukaniswa kwe-centrifugal. I-filtrate ye-centrifugal kanye ne-superstanation yokwakheka kasawoti iqoqwa ethangini le-filtrate yathunyelwa emuva ku-mvr evaporator ukuze ihanjiswe kanye ne-crystallization. I-sodium sulfate ehlukaniswe ne-centrifuge ingena ohlelweni lokumisa.

5. Ukomisa - Ukupakishwa
I-sodium sulfate etholwe kusuka ku-crystallization iqukethe inani elincane lamanzi, futhi ngokuya ngesimo sokuphinda futhi, kunqunywe ukuthi kufanele lisebenzise imishini yomiswa ukunciphisa amanzi. Okokusebenza komiswa kungafakwa ushukela embhedeni (Lawula amazinga okushisa okushisa ~ 150 ℃), vula umbhede ocwebezelayo oshukumisayo kanye nedivaysi yokuqoqa uketshezi, bese ithuthwa eya empumelelweni yokuqothula uketshezi ye-sodium sulfate ukuthola imikhiqizo yesikulufa se-anhydrous sodium sulfate (okuqukethwe kwamanzi <0.5%), ukupakishwa kokuthumela ngaphandle.
