Copper sludge can deliver to recovery process to reclaim valuable metal.
At present, the method for purified treatment waste solution of copper electrolysis is divided into interruption electrodeposition method and continuous electrodeposition method: at interruption electrodeposition method
As shown in Figure 1, the waste solution of copper electrolysis after crystallization separates out copper sulfate is flowed into simultaneously by head tank 1 for the technological process of reason waste solution of copper electrolysis
Electrolytic deposition output cathodic metal black copper in the Winning cell 2 of connection arrangement, the electric effusion then flowing out from Winning cell 2 is in parallel to be flowed into
Lower tank 3, then extract electric effusion from Lower tank 3 with acid-proof pump 4 and be circulated electrodeposition to head tank 1, to improve electrolysis waste solution
Clean-up effect；Continuous electrodeposition method processes the technological process of waste solution of copper electrolysis as shown in Figure 2, and electrolysis waste solution flows through head tank 1
Enter electrolytic deposition in the Winning cell 2 of arranged in series, output cathodic metal black copper, then flow out from last Winning cell 2
Electric effusion flows into Lower tank 3 with use to be discharged, can also realize the purification of logical electrolyte so by way of continuous electrolysis
Process.In general, the copper concentration flowing into the waste solution of copper electrolysis in Winning cell 2 is 45～50g/l, by multiple circulation electrodeposition
Whole outflow Winning cell, the copper concentration of the electrolytic liquid that can enter next procedure are 6～10g/l.
The product black copper being obtained using interruption electrodeposition method and continuous electrode method electrodeposition waste solution of copper electrolysis is all in bulk, these
Block black copper is only applicable to traditional hydrometallurgy to reclaim copper metal, but for " double sudden strain of a muscle " Copper making technique, due to
Flash converting furnace can only process granular material, thus leading to the smelting of melting down of these block black copper to have certain difficulty, therefore
How to ensure the effectively utilizes of the electrodeposition product of waste solution of copper electrolysis, this is the problem that enterprise is being studied always.
Content of the invention
Primary and foremost purpose of the present utility model is that a kind of electrodeposition of the offer waste solution of copper electrolysis that structure is simple, using effect is good is net
Change system.
For achieving the above object, the technical solution adopted in the utility model is: a kind of electrodeposition of waste solution of copper electrolysis purifies system
System it is characterised in that: include the Winning cell that n is sequentially arranged, the waste solution of copper electrolysis after crystallization separates out copper sulfate passes through pipeline and connects
Connect to each Winning cell, the the 1st, 2 ... ..., i ... ..., the material liquid outlet of n-1 Winning cell respectively leads to the 2nd, 3 ... ..., i+
1 ... ..., n Winning cell, the material liquid outlet of n-th Winning cell leads to the 1st Winning cell and electric effusion recovery system, and wherein i is
Natural number between 2～n-1, n >=6.
Using having the beneficial effects that technique scheme produces: compared with prior art, described in the utility model net
Winning cell in change system is the series-parallel connection feeding structure being combined using series, parallel, when specifically used, n-th Winning cell
An electric effusion part for the low copper concentration that material liquid outlet is discharged drains in electric effusion recovery system, and some can introduce first
In individual Winning cell, so can increase total liquid inlet volume of each Winning cell, reduce local copper concentration deviation, and each Winning cell can be reduced
The initial copper concentration of middle feed liquid, thus slowing down speed of separating out on negative electrode for the copper ion, so can be prevented effectively from block black copper
Generation, cleaning system disclosed in this utility model is not only easy to use, and efficiently solves the block electrodeposition of prior art
Black copper cannot directly apply to the problem of double fire refining recovery process dodged in Copper making technique.
Brief description
Fig. 1,2 it is two kinds of prior art purification process charts；
Fig. 3 is cleaning system structure chart of the present utility model.
Specific embodiment
A kind of electrodeposition cleaning system of waste solution of copper electrolysis, as shown in figure 3, it includes the n Winning cell 20 being sequentially arranged, knot
Waste solution of copper electrolysis after partial crystallization goes out copper sulfate leads to each Winning cell 20, the the 1st, 2 ... ..., i ... ..., n-1 by pipeline connection
