Uburyo bwo kugarura sodium sulfate mu ikorwa rya bateri ya lithium

Mu gikorwa cyo kongera gukoresha bateri za lithium ternary na fosfeti y'icyuma ya lithium, aside sulfurike na soda caustic byanze bikunze bihinduka umunyu wa sodium sulfate bitewe n'ikoranabuhanga rikenewe. Umuti usanzwe urimo sodium sulfate ukubiyemo cyane cyane umuti ugarura umunyu wa lithium, umuti uva mu gukora nickel-cobalt ya ternary, amazi ashyushye yo mu bwoko bwa ternary mbere yo kuvurwa, umuti uva mu gukora litium fer phosphate, umuti uva mu gukora litium fer phosphate, umuti uva mu gukora litium lyumu ukoresheje umunyu wa lithium, umuti usigaye uva mu gukora nickel-cobalt-manganese, umuti uva mu gukora nickel-cobalt-manganese, nibindi. Iyi miti isukurwa mu buryo butaziguye cyangwa busukurwa muri sisitemu ya MVR, kandi ikora neza cyane kugira ngo ikore ibicuruzwa bya sodium sulfate idafite amazi. Uburyo bw'ingenzi bwo kuyikora ni ubu bukurikira:

1. Vanga amazi
Ikiyiko cya Ternary nickel-cobalt synthesis, ternary pre-treated discharge brine, lithium iron phosphate nyuma yo guterura lithium, lithium iron phosphate discharge brine, lithium umunyu nyuma yo guterura lithium nickel cobalt manganese salt extraction residue, nickel cobalt manganese synthesis liquid n'ibindi binyobwa bivanze.

2. Gukuraho imyanda no kuyitunganya
Nyuma yo gutegura umuti wa sodium sulfate ukoresheje alkali y'amazi + sodium sulfide kugira ngo ukureho ibyuma biremereye (kanda ku ruhushya ruto rwa nikeli na kobalti, usubize ku ifunguro kugira ngo wongere ukoreshe), hindura PH kuri 5 ~ 7; Nyuma yo gusuzuma, ikigega cy'amazi kibisi cyinjizwamo, maze ikigega cy'amazi kibisi kikagira uruhare mu kubika no kugenzura amazi kibisi kugira ngo gihuze n'imikorere ihoraho ya MVR ikoresha amazi mabi. Ikigega cy'amazi kibisi gifite pompe y'amazi mbisi. Pompe y'amazi mbisi itwara amazi ya sodium sulfate neza mu buryo bungana kuri sisitemu yo gutunganya amazi. Valve yo kugenzura nyuma ya pompe y'amazi mbisi irahindurwa kugira ngo hagumane uburinganire hagati y'ingano y'amazi mbisi iterurwa n'ingano y'amazi aturuka mu mazi.

3. Igisubizo cyo gusubiza
Uduce duto twa sodium sulfate decahydrate twakozwe na sisitemu y'umunyu wa lithium twongerwa mu mazi afunze hanyuma amazi yoza ya lithium yongerwamo kugira ngo habeho umuti wa sodium sulfate wuzuye, ubikwe mu kigega cy'amazi gitandukanye hanyuma bigatwarwa mu buryo butaziguye muri sisitemu ya MVR yo guhumeka no gucukumbura.

4. Guhindura uburyo bwa MVR bwo guhumeka no gushushanya umuti wa sodium sulfate
Umuti w'amazi urimo sodium sulfate ushyushywa n'icyuma gishyushya amazi hanyuma ukinjira mu cyumba cy'umwuka cya sisitemu yo gukaraba ya MVR. Sisitemu yo gukaraba ya MVR ifite icyuma gihindura ubushyuhe gihagaze nyuma ya pompe yo gukaraba. Mu gihe cy'imikorere ya pompe yo gukaraba, amazi y'ibikoresho atembera muri ubwo buryo mu cyumba cy'umwuka - umuhindura ubushyuhe - pompe yo gukaraba yashyizweho - umuhindura ubushyuhe - icyumba cy'umwuka, amazi y'ibikoresho ashyushywa mu muhindura ubushyuhe, hanyuma itandukanyirizo rya gaze-amazi-ikomeye rigaragara mu cyumba cy'umwuka. Umunyu mwinshi woherezwa mu mwobo w'umunyu na pompe yo gukaraba kugira ngo winjire kandi winjire, hanyuma ujugunywe mu gikarabiro cy'umunyu kugira ngo uhuzwe kandi winjire, hanyuma ujugunywe mu gikarabiro cy'umunyu kugira ngo uhuzwe kandi winjire kandi winjire, hanyuma ujugunywe mu gikarabiro kugira ngo uhuzwe. Filtrate ya centrifugal n'icyuma gitandukanya umunyu bikusanyirizwa mu kigega cya filtrate hanyuma bisubizwa mu muhindura wa MVR kugira ngo winjire kandi winjire. Sulfate ya sodium itandukanijwe na centrifuge yinjira mu buryo bw'umuyumu.

5. Kumisha - Gupfunyika
Sulfate ya sodiyumu iboneka mu gukaraba irimo amazi make, kandi bitewe n'uko ikoreshwa mu kongera kuyikoresha, niho hagenwa niba ibikoresho byo kumisha bikoreshwa mu kugabanya amazi. Ibikoresho byo kumisha bishobora gukamurwa mu buryo bw'amazi (kugenzura ubushyuhe bwo kumisha ~ 150℃), gufungura agace gakamurwamo amazi n'igikoresho gishyigikira ivumbi, hanyuma bigatwarwa mu gasanduku gakamurwamo amazi hakoreshejwe icyuma gitanga screw kugira ngo haboneke ibicuruzwa bya sodiyumu ya anhydrous (amazi ari munsi ya 0.5%), bipakirwe mu mahanga.
