Abstract
The utility model discloses a copper electrolysis tank which comprises a tank, a circulating pipe and an electrolyte delivery device, wherein the circulating pipe is communicated with a circulating pump outlet; the electrolyte delivery device comprises at least two delivery pipes communicated with a circulating pipe outlet; the delivery pipes are arranged on the bottom inside the tank; and two side walls of the delivery pipes are respectively provided with an electrolyte diversion outlet. Since the electrolyte delivery device is provided with the at least two delivery pipes communicated with the circulating pipe outlet, the electrolyte enters the delivery pipes from the circulating pump through the circulating pipe in the electrolysis process, thereby greatly increasing the electrolyte flow and lowering the liquid flow rate; and in the electrolysis process, the Cu<2+> diffusion rate is high, so that the electrolysis process is carried out under high current density, and thus, the production efficiency is high.
Description
Technical field
The utility model relates to a kind of copper electrolysis cells.
Background technology
At copper electrolytic process Anodic copper, with the form of bivalent cupric ion, dissolve and obtain electronics on negative electrode after precipitating metal copper.
Anode: Cu-2e=Cu
2+
Negative electrode: Cu
2++ 2e=Cu
In copper electrolytic process, the turnout of copper can be obtained by Faraday's law:
(equation 1)
Wherein, the copper amount of m for producing, unit is gram, the molar mass that M is copper, unit is g/mol; I is current density, and unit is A/m2(amperes per meter 2); A is cathode area, and unit is rice 2; T is the time, and unit is wonderful; Z is for participating in the ion combination valency of reaction; F is Faraday's number, and unit is As/mol.By (equation 1), can be found out, in the situation that the turnout (m) of the constant raising of cathode area (A) copper, only being improved current density (i) can realize.
Again because of, in electrolytic refining course of copper, if positive column Cu
2+anode-the solution interface that can not speed away spreads to cathodic area, will cause positive C u
2+concentration reaches capacity or supersaturation, produces copper sulfate and is deposited on anode surface, and the retardance anodic reaction, raise anode potential, the anode passivation phenomenon occurs.
According to electrode process kinetics of diffusion theory, the anode maximum allowable current density is obeyed following expression formula:
I
a=ZDF
(equation 2)
I in formula
afor maximum allows anodic current density (A/m
2); Z is for participating in the electronic number of reaction; F is Faraday's number; △ C is anode surface Cu
2+the Cu of saturation concentration and electrolytic solution body
2+concentration difference (kmol/m
3); δ is thickness of diffusion layer (m); D is spread coefficient (m
2/ s).D is by stokes-einstein formula decision, that is:
In formula: k is Boltzmann constant; T is absolute temperature (K); R is diffusion ion (or particle) radius (cm); Viscosity (Pa S) for electrolytic solution.
To in current density being 200,300,400A/m
2, Cu
2+and H

4concentration be respectively 40 and 190g/l, temperature be that the research of carrying out electrolysis under 65 ℃ of conditions is pointed out, the cathode surface thickness of diffusion layer is 0.1～0.2mm, Cu in cathode surface and electrolytic solution body
2+concentration differs and reaches 15～24g/l.
From (equation 2) and (equation 3), control higher electrolyte temperature, increase the internal circulating load of electrolytic solution, and suitably reduce Cu in electrolytic solution
2+concentration, be conducive to improve Cu
2+velocity of diffusion, can make electrolytic process carry out under larger current density and be unlikely to produce anode passivation.At present, electrolytic process generally adopts a transfer lime conveying electrolyte, circulation of elecrolyte amount and Cu
2+velocity of diffusion slow, cause electrolytic efficiency low.
The utility model content
The utility model purpose is to provide a kind of circulation of elecrolyte amount and Cu
2+the copper electrolysis cells that velocity of diffusion is fast, electrolytic efficiency is high.
In order to solve the problems of the technologies described above, copper electrolysis cells of the present utility model, comprise groove and circulation tube, described circulation tube and circulating-pump outlet UNICOM,, also comprising the electrolytic solution e Foerderanlage, described electrolytic solution e Foerderanlage comprises at least two transfer limes with circulation tube outlet UNICOM, described transfer lime is placed in the groove inner bottom part, and described transfer lime two side is provided with electrolytic solution shunting outlet.
Adopt structure of the present utility model, due to the electrolytic solution e Foerderanlage be provided with at least two with transfer lime with circulation tube outlet UNICOM.When electrolytic process carries out, electrolytic solution enters transfer lime by recycle pump through circulation tube, has greatly increased flow of electrolyte, and has reduced flow rate of liquid, Cu in electrolytic process
2+velocity of diffusion fast, electrolytic process is carried out under larger current density, production efficiency is high.
Described transfer lime is two and exports UNICOM by threeway and circulation tube.
The electrolytic solution shunting outlet of described two transfer limes mutually alternately.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1 along the A-A line.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
