Description
技术领域 technical field
本实用新型涉及电解槽，尤其是涉及一种用于高纯金属镍电积冶炼的电解槽。The utility model relates to an electrolytic cell, in particular to an electrolytic cell for electrowinning smelting of high-purity metal nickel.
背景技术 Background technique
随着国内有色产业的蓬勃发展，有色产品的产量逐年攀升，特别是中国不锈钢行业的飞速发展及国产化，国内镍金属板材的用量及产量逐年提高，尤其是高纯四九金属镍电积板材，但镍资源却日趋紧张。作为镍电积，在硫酸盐体系中，普遍采用铅合金阳极，该阳极在电解过程中，表面上形成一层氧化铅(PbO2)阳极膜。该膜不是十分致密，容易被电解过程中在阳极析出的氧气冲落。悬浮在电解液中的PbO2微粒也极易附着于电积镍表面，在电解过程中包裹在阴极镍板内，增加金属镍的含铅量，降低电积镍质量。为此，镍电积工艺均采用隔膜的形式把阴阳极分开。已公开的工艺都采用阴极隔膜袋，就是用隔膜袋将阴极包起来。大型镍冶炼厂，每个电解槽有阴极隔膜袋60多个，每个隔膜袋都需安置一个可控进液管，以调节每个隔膜袋的进料量。全车间总的进液管数量达数千个。不但增加操作人数，而且要实现槽内各袋之间的流量均衡控制，操作难度也极大。因此，如何解决上述这些问题，达到金属镍品质特极(含镍99.96％-99.99％)，成本最低，生产效率较高，是急需进一步探讨的问题。。With the vigorous development of the domestic non-ferrous industry, the output of non-ferrous products has been increasing year by year, especially the rapid development and localization of China's stainless steel industry, the consumption and output of domestic nickel metal plates have increased year by year, especially high-purity 49 metal nickel electrodeposited plates , but nickel resources are increasingly tight. As nickel electrowinning, lead alloy anode is commonly used in sulfate system, and a layer of lead oxide (PbO 2 ) anode film is formed on the surface of the anode during the electrolysis process. The film is not very dense and is easily washed off by the oxygen precipitated at the anode during the electrolysis process. The PbO2 particles suspended in the electrolyte are also very easy to attach to the surface of the electro-deposited nickel, and are wrapped in the cathode nickel plate during the electrolysis process, increasing the lead content of the metal nickel and reducing the quality of the electro-deposited nickel. For this reason, the nickel electrowinning process adopts the form of diaphragm to separate cathode and anode. The disclosed technology all adopts the cathode membrane bag, is exactly to wrap the cathode with the membrane bag. In a large nickel smelter, each electrolytic cell has more than 60 cathode diaphragm bags, and each diaphragm bag needs to be equipped with a controllable liquid inlet pipe to adjust the feeding amount of each diaphragm bag. The total number of liquid inlet pipes in the whole workshop reaches thousands. Not only does it increase the number of operators, but it is also extremely difficult to realize the flow balance control among the bags in the tank. Therefore, how to solve the above-mentioned problems to achieve extremely high-quality nickel (containing 99.96%-99.99% nickel), the lowest cost, and high production efficiency is a problem that urgently needs to be further discussed. .
发明内容 Contents of the invention
本实用新型的目的在于提供一种电解槽的阴极区溶液PH值稳定、电流效率高、产品可达到金属镍板品质特极、成本低、生产效率较高的用于高纯金属镍电积冶炼的电解槽。The purpose of the utility model is to provide a solution in the cathode area of the electrolytic cell with stable pH value, high current efficiency, extremely high-quality metal nickel plate, low cost and high production efficiency for high-purity metal nickel electrowinning smelting electrolyzer.

阳极板为钛涂铱阳极板。The anode plate is a titanium-coated iridium anode plate.
阳极隔膜袋由涤纶和棉纶混纺而成。Anode separator bags are made of polyester and cotton blend.
本实用新型将传统电解槽的阴极板外套有阴极隔膜袋、电解液通过进液支管注入阴极隔膜袋和溢流堰设在槽体侧壁进行了重新设计，改成了：在钛涂铱阳极板外套有阳极隔膜袋，电解液通过进液管直接注入槽体内，在槽体内的底部安装有封闭的底流管、阳极隔膜袋的底部与底流管通过连接管连接，这样在硫酸体系中进行镍的电解，具有以下优点：In the utility model, the cathode plate of the traditional electrolytic cell is covered with a cathode diaphragm bag, and the electrolyte is injected into the cathode diaphragm bag through the liquid inlet branch pipe and the overflow weir is set on the side wall of the cell body for redesign. The plate is covered with an anode diaphragm bag, and the electrolyte is directly injected into the tank through the liquid inlet pipe. A closed underflow pipe is installed at the bottom of the tank body, and the bottom of the anode diaphragm bag is connected to the underflow pipe through a connecting pipe, so that nickel The electrolysis has the following advantages:
1、电解槽的阴极区溶液PH值稳定，溶液成分比较稳定，使阴极区溶液成分不易受隔膜袋渗漏而造成溶液成分的大幅度改变。1. The pH value of the solution in the cathode area of the electrolytic cell is stable, and the solution composition is relatively stable, so that the solution composition in the cathode area is not easily affected by the leakage of the diaphragm bag and causes a large change in the solution composition.
2、电流效率高。在电解过程中申请人观察到：当阴极液PH值低于2.5时，阴极板产生的氢气泡，随着PH值的继续降低而迅速增多。因此，电解槽的阴极区PH值稳定，是电流效率较高的主要因素。2. High current efficiency. During the electrolysis process, the applicant observed that when the pH value of the catholyte was lower than 2.5, the hydrogen bubbles generated by the cathode plate increased rapidly as the pH value continued to decrease. Therefore, the stable pH value of the cathode area of the electrolytic cell is the main factor for the high current efficiency.
3、经济效益显著。通过1、2所述的条件控制，不仅整个系统稳定、操作简单、劳动强度减小，提高了工作效率，而且电流效率高，保证产品质量稳定，电积镍质量可满足特号镍的国家标准。3. Significant economic benefits. Through the control of the conditions mentioned in 1 and 2, not only the whole system is stable, the operation is simple, the labor intensity is reduced, and the work efficiency is improved, but also the current efficiency is high, ensuring stable product quality, and the quality of electrodeposited nickel can meet the national standard of special nickel .
4、本实用新型也适用于高纯金属钴电积的冶炼。4. The utility model is also applicable to the smelting of high-purity metal cobalt electrowinning.
