Application of Vacuum Pumps in Battery Recycling
Waste dry cell batteries, containing various heavy metals, pose a significant environmental hazard if not properly disposed of. Directly discarding them not only pollutes the environment but also represents a considerable waste of resources. Processing these batteries to eliminate their environmental hazards and recover valuable materials has been the focus of many researchers worldwide for years. The Role of Vacuum Pumps in Battery Recycling: The primary principle of using vacuum pumps in the treatment of waste dry cell batteries lies in the fact that the components of these batteries have different vapor pressures at the same temperature. Through evaporation and condensation in a vacuum environment, the components can be separated at different temperatures, facilitating comprehensive recovery and utilization. The process typically involves two main steps: Mercury Recovery: Mercury, which is easily volatile, is evaporated and condensed at around 300°C in a vacuum. This step effect
