Maitiro ekudzoreredza sodium sulfate mukugadzirwa kwebhatiri re lithium
Mukushandiswazve kwemarara emabhatiri e-ternary lithium uye mabhatiri e-lithium iron phosphate, sulfuric acid necaustic soda zvinoshandurwa kuita sodium sulfate salts nekuda kwezvinodiwa netekinoroji. Mhinduro isina kubikwa ine sodium sulfate inonyanya kusanganisira mhinduro yekudzosa ye lithium salt system, mhinduro mushure mekugadzirwa kwe ternary nickel-cobalt, ternary pre-treatment discharge brine, mhinduro mushure mekudya kwe lithium iron phosphate, mvura inobuda ye lithium iron phosphate, mhinduro mushure mekudya kwe lithium lithium ne lithium lithium salt, mhinduro yakasara ye nickel-cobalt-manganese salt extraction, mhinduro mushure mekudya kwe nickel-cobalt-manganese, nezvimwewo. Mhinduro idzi dzinocheneswa zvakananga muMVR evaporation system, uye dzinonyanya kucheneswa uye kuomeswa kuti dzigadzire anhydrous sodium sulfate products. Maitiro makuru ekugadzira ndeaya anotevera:
1. Sanganisa mvura yacho
Mvura yakagadzirwa ne nickel-cobalt yakasanganiswa, mvura yakasanganiswa yakasanganiswa ne ternary, phosphate yesimbi yakasanganiswa ne lithium mushure mekugadzika, phosphate yesimbi yakasanganiswa ne lithium, munyu we lithium mushure mekugadzika ne lithium nickel cobalt manganese munyu wakabviswa ne nickel, nickel cobalt manganese synthesis liquid nezvimwe zvinwiwa zvakasanganiswa.
2. Kubvisa tsvina uye kunatsa
Mushure mekugadzirira sodium sulfate solution ne liquid alkali + sodium sulfide depth kubvisa heavy metals (dzvanya sefa shoma ye nickel ne cobalt slag, dzorera ku feed kuti ishandiswezve), gadzirisa PH kusvika pa 5~7; Mushure mekunge ongororo yaitwa, raw liquid tank inopinzwa, uye raw liquid tank inoita basa rekuchengetedza uye kudzora raw liquid kuti isangane nekushanda kwakasimba kweMVR wastewater evaporator. Raw liquid tank ine raw liquid pombi. Raw liquid pombi inofambisa sodium sulfate aqueous solution zvakaenzana kuenda ku evaporation treatment system. Control valve mushure me raw liquid pombi inogadziriswa kuti ichengetedze chiyero pakati pe liquid inosimudza uye evaporation.
3. Mhinduro yekudzosa
Makristaro e sodium sulfate decahydrate anogadzirwa ne lithium salt system anowedzerwa mumvura yakakomberedzwa uye mvura ye lithium wash iri pasi pemvura inogadzirwa kuti igadzire sodium sulfate solution inenge yazara, iyo inochengetwa mutangi remvura rakasiyana uye yozoendeswa zvakananga kuMVR evaporation and concentration system.
4. MVR evaporation uye crystallization ye sodium sulfate solution
Mvura ine sodium sulfate inopiswa ne condensate preheater yobva yapinda mu evaporation chamber ye MVR evaporation crystallization system. MVR evaporation system ine vertical heat exchanger mushure me forced circulation pomp. Pasi pekushanda kweforced circulation pomp, the material liquid inoyerera mu evaporation chamber yakadaro - heat exchanger - forced circulation pomp - heat exchanger - evaporation chamber, the material liquid inopiswa mu heat exchanger, uye gas-liquid-solid separation inowanikwa mu evaporation chamber. The concentrated salt slurry inotumirwa kunzvimbo inobuda salt ne discharge pomp kuti iunganidzwe uye iunganidzwe uye iparadzaniswe, uye pakupedzisira inoburitswa mu centrifuge kuti iparadzaniswe. Centrifugal filtrate ne salt separator supernatant zvinounganidzwa mu filtrate tank zvodzoserwa ku MVR evaporator kuti iparadzirwe uye igadzire crystallization. Sodium sulfate yakaparadzaniswa ne centrifuge inopinda mu drying system.
5. Kuomesa - Kurongedza
Sodium sulfate inowanikwa kubva mukuumbwa kwekristaro ine mvura shoma, uye zvichienderana nemamiriro ekushandiswazve, zvinoonekwa kana michina yekuomesa ichishandiswa kuderedza mvura. Midziyo yekuomesa inogona kuomeswa pamubhedha (kudzora tembiricha yekuomesa ~ 150℃), kuvhura mubhedha unodedera uye mudziyo wekuunganidza guruva unotsigira, wozoendeswa kunzvimbo yekuomesa pamubhedha unodedera uchishandisa sikuruu kuti uwane zvigadzirwa zve sodium sulfate (huwandu hwemvura
