Description
Technical Field
The utility model relates to the technical field of hydrometallurgy, in particular to an electrolysis device for metal electrorefining, which is simple to operate, high in electrolysis efficiency and good in electrolysis product quality.
Background
Electrorefining is a common purification technique for hydrometallurgy. In the process of electrolysis, crude metal is used as an anode, a salt solution containing metal to be prepared is used as electrolyte, and impurities with the dissolving potential being more positive than that of refined metal are remained in the anode or deposited in anode mud by controlling the electrolysis potential, and are separated and recovered by other methods; and impurities with a dissolution potential more negative than the refined metal dissolve into the solution and do not precipitate on the cathode, thereby obtaining refined high-purity metal on the cathode. Electrolytic refining has been used to separate and purify valuable metal elements, which are used in many ways in the purification of copper, zinc, silver and various noble metals.
At present, in the electrolytic refining process, heat balance and material balance are two major conditions of stable operation of electrolysis: the low temperature in the electrolysis process affects the electrolysis efficiency, and the high temperature easily causes a large amount of bubbles to be attached to the surface of the cathode, affects the surface quality of refined metal and prevents metal deposition; in the electrolysis process, the concentration of the electrolyte is uneven, so that the homogeneous degree and concentration polarization phenomenon of the electrolyte are caused, and the voltages of all the polar plates are inconsistent, thereby affecting the electrolysis efficiency and the quality of the electrolyzed product.
In the prior art, in order to solve the heat balance problem in the electrolysis process, a mode of directly introducing steam into the electrolyte to directly control the temperature exists, but a large amount of water is brought in to cause the imbalance of the components of the electrolyte; the water jacket or the oil jacket is arranged outside the electrolytic tank, and the electrolyte is indirectly heated through hot water or hot oil, but the structure is complex, so that the risk of leakage and pollution of the electrolyte exists, and the replacement of a heating part in the water jacket or the oil jacket is complicated; there are also heating parts added in the liquid storage tank of the electrolyzer, which is solved by directly supplying the hot electrolyte into the electrolyzer, but the electrolyte circulation amount is smaller because the volume of the electrolyzer is larger, the electrolyte with higher temperature needs to be introduced to maintain the temperature in the electrolyzer, and the excessive temperature can cause the change of part of components in the electrolyte, thereby influencing the normal operation of the electrolysis. In order to solve the material balance problem, an analysis device and a feeding mechanism are added on a liquid storage tank or an electrolytic tank to maintain the material balance of electrolyte supplied into the electrolytic tank, but the electrolyte is easy to generate upper and lower layering in the electrolytic tank, and is highest at an electrolyte inlet, and is lowered to an electrolyte outlet along with electrolysis consumption, so that the electrolyte in the electrolytic tank is unbalanced; for this reason, there are also solutions in which stirring means are added to the upper part or side part of the electrolytic cell, but the electrolytic electrode is limited due to the occupation of the electrolytic space, which affects the electrolytic efficiency, and the surface quality of the electrolytic product is also affected by the vigorous stirring of the electrode side. Therefore, the temperature control of the electrolyte, the homogeneous degree of the electrolyte and the concentration polarization phenomenon in the electrolysis process are difficult to solve or eliminate, so that a plurality of researchers have improved ideas, such as a cyclone electrolysis technology, and part of technical indexes are improved in production. However, improvements such as cyclone electrolysis technology not only have the problem of high equipment design, manufacturing and maintenance costs, resulting in insufficient coverage of application, but also have less closely related research and production because of different requirements from basic experimental research to industrial production.
