The electrolytic solution treatment and crushing and separation of alkaline batteries

In the environmental protection recycling process of alkaline batteries, electrolyte treatment and crushing and separation are two vital links. These two steps are not only directly related to the recovery efficiency, but also affect the environmental friendliness and resource utilization rate in the recovery process. The following is a detailed analysis of these two links.
Electrolyte treatment
Neutral treatment is the key step of electrolyte treatment. By adding an appropriate amount of acidic substances to the electrolyte, the pH value of the electrolyte can be reduced to the safe range of the pH value of the electrolyte. Salt precipitates generated during the neutralization process can be separated and processed by filtering. It should be noted that neutralization should be performed in a closed container to prevent harmful gases from reaching out.
Waste liquid treatment
After neutralized waste liquid, although its pH value has dropped to the safe range, it may still contain some pollutants that are difficult to completely remove. Therefore, these waste liquids need to be further treated, such as chemical precipitation, adsorption, membrane separation and other technologies to minimize the pollutants. The treated waste liquid can be discharged to the sewage pipe network or other forms of environmental protection disposal.
Broken and separated
Broken is a step in the recycling process of alkaline battery, and it is also a key step to separate the battery components. At present, the commonly used crushing equipment includes hammer crusher and shear crusher. These devices crushed the battery shell and electrode into smaller particles or fragments through the role of physical power.
 Siege and separation
The broken battery fragments need to be screened and separated to separate the electrode materials, electrolytes, and shells. During the screening process, the sieve network with different pores can be used for classification according to the different particle size. During the separation process, the physical properties of the electrode material, the electrolyte, and the shell can be used to separate the physical properties of the parts, and the separation of magnetic selection, floating, and vortex separation.
