Description
Technical field
The utility model belongs to metal smelt technical field, and in particular to a kind of circulation electrolysis unit.
Background technique
Aqueous solution electrolysis technique in electrolytic process, is placed on anode and cathode in the groove body that electrolyte slowly flows,
Under the action of electric field, anion is to anode displacement, and cation is to cathode displacement, by controlling certain technology item
Part, metal target cation obtains electrolytic deposition in cathode and is precipitated, to obtain high-purity electrolytic production.
Metal abides by Faraday's law during aqueous solution electrolysis, and by taking copper as an example, electrolysis amount of precipitation can use following formula
It indicates:
mCu=1.1852iAt
In formula: mCu: the copper mass (g) of precipitation, i: current density (A/m2), A: cathodal closing area (m2), t: when energization
Between (s).
By above formula, in the case where energization area is constant, only it is improved to improve tough cathode yield within the unit time
Current density.
In production practice, when current density is higher, biggish circulation rate should be used, to reduce concentration polarization.But
It is that circulation rate is too fast, and the earth of positive pole can be made not easily settled, and the loss of noble metal is caused to increase, also results in cathode matter sometimes
Measure deterioration and plate face largely long particle.Under high current density, electrolyte concentration polarization phenomenon is more serious, it is therefore desirable to choose and close
Suitable endless form.
Currently, the endless form mainly used has following several in aqueous solution electrolysis metallurgical production:
The first, upper intake lower outlet type circulation, electrolyte is directly entered the top of electrolytic cell from electrolytic cell one end, in electrolytic cell
The other end is equipped with water bag (or water outlet partition), and the electrolyte of electrolytic cell lower part is exported.
Second, bottom in and top out formula circulation, electrolyte imports electricity from the inlet tube (or in water inlet partition) of electrolytic cell one end
The lower part for solving slot, flows from bottom to top in slot, overflows from electrolytic cell other end top overflow pipe.
The third, central bottom tube aperture feed liquor circulation, overflow efflux at both ends.
4th kind, parallel jet electrolysis process (Chinese patent CN2068512U), from electrolytic cell side after electrolyte is pressurized
Face bottom liquid inlet, overflow efflux at both ends.
5th kind, top feed liquor two-way parallel flow electrolysis process (Chinese patent CN104831319A), electrolyte is from electrolysis
Two sides while feed liquor at the top of slot groove body, and take the circulation feed liquor mode of upper entering and lower leaving.
Above-mentioned several endless form can have following technical disadvantages in aqueous solution electrolysis metallurgical production:
1) the first above-mentioned endless form.In the electrolytic cell of upper entering and lower leaving, the floating earth of positive pole is contrary with feed liquor, no
Outside easy removal slot.In addition, feed liquor mode is that feed liquor is concentrated in electrolytic cell one end, and partial electrolysis liquid mass transfer and heat-transfer effect are poor, in slot
Bottom easily crystallizes, and ion concentration dilution is serious, is unfavorable for the significantly promotion of current density.
2) above-mentioned second of endless form, in the electrolytic cell of bottom in and top out, feed liquor mode be electrolytic cell one end concentrate into
Phenomena such as liquid equally exists electrolyte dispersion unevenness, is unfavorable for mass transfer and heat transfer, is unfavorable for the significantly promotion of current density.
3) the third above-mentioned endless form, electrolyte feed liquor direction is substantially and pole plate is vertical.On the one hand, two sides and bottom
There is circulation dead zone in portion, solution composition is unevenly distributed, and local depletion is serious, easily causes cathodic polarization unbalance and anodic passivity, shadow
Ring quality control.On the other hand, in use process, feed liquor aperture needs stringent alignment cathode plate face, but because a variety of causes causes
Bottom tube deformation (such as falling anode scrap) perhaps installation site it is improper occur feed liquor aperture blow-through anode plate or disorderly blow phenomenon, cause
Electrolytic cell liquid stream disorder, influences quality control.
4) above-mentioned 4th kind of endless form, power consumption is big, investment is high, and a whole set of circulatory system component is more, mostly uses
Stainless steel material.And easily there is blocking, damage in injection apparatus, high failure rate, maintenance cost is high and additional increased heavy workload.
5) above-mentioned 5th kind of endless form includes shortcoming in 4).And this patent is using upper entering and lower leaving principle,
Equally existing the floating earth of positive pole in 1), to be not easy slot inner cathode lower area electrocrystallization under removal slot is outer and high current density poor etc.
Problem is unfavorable for cathode product quality control.
