Description
Technical Field
The invention belongs to the technical field of recycling treatment of solid wastes, in particular relates to a recycling treatment method of waste zinc-manganese batteries such as zinc-manganese dry batteries and alkaline zinc-manganese batteries, and belongs to an innovative technology for recycling the waste zinc-manganese batteries.
Background
Batteries have found widespread use in many areas of modern society. Particularly, china has become a world with battery production and export through the product structure adjustment in recent years in the battery industry. In 2008, the sales income of the battery industry exceeds 2000 million yuan, the output of the chemical batteries exceeds 320 million, and the export quantity exceeds 250 million. The production of zinc-manganese batteries (including zinc-manganese dry batteries and alkaline zinc-manganese batteries) accounts for about two-thirds of the production. It is estimated that each 10 million alkaline zinc manganese cells produced will consume 0.52 million tons of metallic zinc, 1.1 million tons of manganese dioxide, 906 tons of copper, 0.45 million tons of cold rolled steel, and 0.16 million tons of potassium hydroxide. Because each active substance used for producing the battery still exists in the battery after the service life of the battery is over, the recovery treatment of the waste battery can realize the recycling of the substances such as zinc, manganese and the like contained in the battery, relieve the increasingly severe global resource pressure and solve the potential pollution problem of the waste battery to the environment.
In the last decades, people mainly treat valuable substances in waste zinc-manganese batteries based on a pyrometallurgical or hydrometallurgical process flow when researching the recovery treatment technology of the zinc-manganese batteries. The methods generally crush the battery, and then sequentially separate and recover mercury, zinc, manganese, copper, electrolyte and the like. The pyrometallurgical process is sequentially separated according to the volatility difference of different substances in the battery under the high-temperature condition, and the method has the advantages of short process flow, high recovery efficiency and large energy consumption and equipment investment; the wet-process metallurgy method dissolves the battery waste materials firstly and then separates the battery waste materials, has complex process flow, is easy to realize the respective recovery of different species in the battery, and can bring secondary pollution. With the technical progress, the use of common zinc-manganese dry batteries is gradually eliminated in recent years, and mercury-free alkaline zinc-manganese batteries are used for mass production and use instead. The alkalization rate has been reported to approach 90% in some developed countries, and 50% in china, and this figure is increasing at a constant rate. It is foreseen that the waste zinc manganese cells faced in the near future will be mainly mercury-free alkaline zinc manganese cells.

1) Crushing the battery and recovering electrolyte;
2) Separating iron and organic matter components from the washed crushed material;
3) Acid dissolving and separating the remainder;
4) Recovering zinc from the filtrate.
In the step 1), the shell of the waste battery is opened, and then the electrolyte in the waste battery is separated by a water washing method.
The shell of the battery in the step 1) is firstly broken and opened, the pole core material can fall off from the shell in the subsequent ball milling process, and the electrolyte is recovered by a filtering method after the broken material is soaked by adding water.
In the step 2), an iron shell, a conductive rod, a diaphragm, an outer packaging film and an organic matter component of a sealing ring are separated from the water-washed crushed objects by using a method comprising ball milling, screening and magnetic separation.
And 2) performing ball milling on the water-washed crushed materials by using a ball mill in the step 2) to enable the battery pole core materials to fall off from the battery shell, then separating the battery shell, the battery pole core conductive rod and the organic matter components by using a screening method, and finally separating the diaphragm, the outer packaging film and the sealing ring by using magnetic separation.
In the step 3), the rest separated out of iron and organic components is dissolved by using sulfuric acid, and then the dissolved matter is filtered to respectively obtain a filtrate containing zinc ions and filter residues containing manganese compounds.
Dissolving the remainder of separated iron and organic components by using 0.5-6mol/L sulfuric acid in the step 3), and then respectively obtaining filtrate containing zinc ions and filter residue containing manganese compounds by using a filtration method.
In the step 4), zinc in the filtrate is recovered by an electrolytic deposition method.
And (5) electrolyzing in the step 4) by using a lead plate or a titanium plate as an electrode material of the electrolytic cell, and obtaining the metal zinc on the cathode by a direct current electrolysis method.

At present, zinc-manganese dry batteries in waste zinc-manganese batteries mainly use zinc as a shell, alkaline zinc-manganese batteries use iron as a battery shell, and collected waste zinc-manganese batteries are generally a mixture of the two types of batteries. Many zinc-manganese batteries also use iron as the current collector for the battery electrodes. In general, the iron is used in a large amount in the whole waste zinc-manganese battery, and the iron is recovered by the ironHigh value zinc has a great influence. Therefore, the iron separation method directly influences the formulation of the recycling treatment process flow and the economic benefit of the process. In the invention, the iron component in the crushed material is separated by a screening method after the battery is crushed and the electrolyte is washed away, thereby simplifying the process flow and reducing the requirements of the process on equipment and chemicals. In addition, the crushed materials are washed by water to recover the electrolyte, and then the washed materials are subjected to ball milling treatment, so that the pole core materials can fall off from the battery shell and the conducting rod in a small particle form, the subsequent screening and separating operation requirements are met, and the purpose of separating an iron shell, the conducting rod, organic components and the like from the crushed materials is realized. The undersize obtained in the screening process is mainly zinc, zinc compounds and manganese compounds. In addition, the invention utilizes the characteristic that zinc and the chemical combination energy thereof are dissolved in sulfuric acid, and manganese dioxide is not dissolved in dilute sulfuric acid, so that the aim of dissolving zinc in undersize with sulfuric acid with a certain concentration and then separating manganese by a filtering method can be realized. The filter residue obtained by filtering is a manganese compound, and can be directly dried and sold as a raw material. The ions in the filtrate are mainly zinc ions, but the product after the manganese dioxide discharge can be partially dissolved into divalent manganese ions to enter the solution, so the filtrate also contains a small amount of manganese ions. Compared with the methods of organic matter extraction, chemical precipitation and the like, the method adopts an electrolysis method to separate zinc and manganese ions in the solution containing divalent zinc ions and manganese ionsThe preferred method of manganese. In particular, the method can directly obtain high-purity electrolytic zinc. In the process of electrolyzing zinc, because the room temperature environment condition is adopted, manganese ions can be left in the electrolyte. ZnSO in electrolyte during electrolysis 4 The content of (A) is controlled to be 160-50g/L, so that the current efficiency of the whole electrolysis process can be improved. The acidity of the electrolyzed solution is increased and the solution can be reused in the previous acid dissolution step. When the manganese content in the residual solution after electrolysis is excessively high, the manganese is separated in the form of manganese dioxide by using a method of alkali precipitation, roasting and sulfuric acid dissolution. Whole recovery pointAfter the treatment is finished, electrolyte, an iron shell, a conductive rod, zinc and manganese compounds, a diaphragm, a sealing ring, an outer packaging film and the like can be obtained. In particular, the method has no high-temperature roasting process, so that the generation of secondary pollutants in the waste gas can be avoided. Although sulfuric acid is used in the zinc-manganese separation process, the acid shows the characteristic of being reusable in combination with the subsequent electrolytic separation process, and the consumable is actually water, so that the possibility of secondary pollution caused by the acid is low. When treating a high manganese content electrolyte, the recovered electrolyte may be used for acid neutralization and precipitation. The characteristics of the process flow not only can ensure that the secondary pollutants generated in the whole recovery process are few and can be treated harmlessly, but also can improve the economic benefit of the whole flow. Compared with the prior art, the invention has the following advantages or effects:
1) The method for recycling the zinc-manganese dry battery and the alkaline zinc-manganese battery is a disposable battery which is most widely used at present, and the method not only can solve the environmental protection problem caused by the waste batteries, but also can realize the recycling of valuable substances contained in the waste batteries.
