Usoro mgbake nke sodium sulfate na mmepụta batrị lithium

N'ime usoro imegharị ihe nke batrị lithium na batrị lithium iron phosphate, a na-agbanwe sulfuric acid na caustic soda ka ọ bụrụ nnu sodium sulfate n'ihi ihe teknụzụ chọrọ. Ngwọta e ji mee ihe nke nwere sodium sulfate gụnyere ihe ngwọta nlọghachi nke sistemụ nnu lithium, ihe ngwọta mgbe ejiri nickel-cobalt mee ihe, ihe ngwọta tupu ọgwụgwọ ternary, ihe ngwọta mgbe ejiri lithium iron phosphate mee ihe, ihe ngwọta mgbe ejiri lithium iron phosphate mee ihe, ihe ngwọta mgbe ejiri lithium lithium mee ihe mgbe ejiri lithium nnu mee ihe, ihe ngwọta fọdụrụ nke mwepụ nnu nickel-cobalt-manganese, ihe ngwọta mgbe ejiri nickel-cobalt-manganese mee ihe, wdg. A na-asacha ngwọta ndị a ozugbo ma ọ bụ sachaa ha n'ime sistemụ evaporation MVR, yana kristal na nkụcha kachasị iji mepụta ngwaahịa sodium sulfate anhydrous. Usoro mmepụta bụ isi bụ ndị a:

1. Gwakọta mmiri mmiri ahụ
Mmiri mmepụta nickel-cobalt nke Ternary, mmiri mwepụ brine nke a gwọchara tupu oge eruo, lithium iron phosphate mgbe ọ kwụsịrị lithium, lithium iron phosphate nke a chụpụtara brine, nnu lithium mgbe ọ kwụsịrị lithium nickel cobalt manganese nke a chụpụtara nnu nickel residue, nickel cobalt manganese nke a chụpụtara mmiri na mmiri ndị ọzọ agwakọtara agwakọta.

2. Iwepụ ihe ndị na-adịghị ọcha na ime ka ha dị ọcha
Mgbe emechara nkwadebe mmiri sodium sulfate site na mmiri alkali + sodium sulfide omimi iji wepụ ọla dị arọ (pịa nzacha obere nickel na cobalt slag, weghachite na nri maka iji ya mee ihe ọzọ), gbanwee PH ka ọ bụrụ 5~7; Mgbe emechara nyocha ahụ, a na-abanye na tankị mmiri mmiri raw, tankị mmiri mmiri raw na-arụkwa ọrụ nke ịchekwa na ịchịkwa mmiri raw iji mezuo ọrụ na-aga n'ihu na nke kwụsiri ike nke MVR water evaporator. Tankị mmiri mmiri raw nwere ọkpọkọ mmiri raw. Mgbapụta mmiri mmiri raw na-ebuga ngwọta mmiri sodium sulfate n'ụzọ kwụ ọtọ na sistemụ ọgwụgwọ evaporation. A na-agbanwe valvụ njikwa mgbe mgbapụta mmiri raw gasịrị iji nọgide na-enwe nguzozi n'etiti oke ibuli mmiri raw na oke evaporation.

3. Ngwọta nloghachi
A na-agbakwunye kristal sodium sulfate decahydrate nke sistemụ nnu lithium mepụtara na mmiri a kpọchiri akpọchi na mmiri ịsa lithium dị n'ime mmiri iji mepụta mmiri sodium sulfate fọrọ nke nta ka ọ bụrụ nke jupụtara, nke a na-echekwa na tankị mmiri dị iche wee buru ya ozugbo na sistemụ MVR evaporation na integration.

4. Mwepụ MVR na kristal nke ngwọta sodium sulfate
A na-eji ihe na-ekpo ọkụ condensate eme ka mmiri mmiri nwere sodium sulfate dị ọkụ wee banye n'ime ụlọ ikuku nke sistemụ ikuku MVR. Sistemụ ikuku MVR nwere ihe na-agbanwe okpomọkụ kwụ ọtọ mgbe mgbapụta ikuku amanye gasịrị. N'okpuru ọrụ nke mgbapụta ikuku amanye, mmiri ihe ahụ na-asọfe n'ime usoro ikuku evaporation dị otú ahụ - ihe na-agbanwe okpomọkụ - ihe na-agbanwe okpomọkụ - ihe na-agbanwe okpomọkụ - ụlọ ikuku evaporation, a na-ekpo ọkụ mmiri ihe ahụ n'ime ihe na-agbanwe okpomọkụ, a na-ahụkwa nkewa gas-mmiri siri ike n'ime ụlọ ikuku evaporation. A na-eziga nnu nnu a na-etinye n'ime oghere nnu site na mgbapụta ikuku evaporation maka njupụta na nkewa, wee wụpụ ya n'ime sink nnu maka nchịkọta na njupụta na nkewa, ma mechaa wụpụ ya n'ime centrifuge maka nkewa centrifugal. A na-anakọta filtrate centrifugal na ihe na-ekewa nnu n'ime tankị filtrate ma weghachite ya na MVR evaporator maka ikuku evaporation na kristal. Sodium sulfate nke kewapụrụ na centrifuge na-abanye na sistemụ nkụ.

5. Ịkpọ nkụ - Nkwakọ ngwaahịa
Sodium sulfate nke e nwetara site na kristal nwere obere mmiri, dabere na ọnọdụ eji eme ihe ọzọ, a na-ekpebi ma a ga-eji ngwa nkụcha iji belata mmiri.
