Description
Spent lead-acid battery typically come from scrapped automobiles and electric bicycles. Depending on structural and functional differences, lead-acid batteries can be categorized into flooded (wet) lead-acid batteries for starting applications, valve-regulated (dry) lead-acid batteries for power applications, and other types. Spent lead-acid batteries contain 24%--30% (by mass) of lead alloy components such as grid plates and terminals.
The grid plates recovered from dismantling spent lead-acid batteries have a high lead content and are directly fed into smelting furnaces after separation. The smelting temperature is approximately 900--1000 °C. Since the grid plates still carry some residual sludge, pollutants such as lead dust and lead slag are generated during the smelting process. This dataset is applicable to the smelting process of grids in spent lead-acid batteries.
Activity Description
This dataset represents the process of removing impurities from grid materials through pyrometallurgical refining, including energy and auxiliary material consumption, as well as emissions of water pollutants, air pollutants, and solid waste.
Process Description
Put the grid into the refining furnace for refining to remove impurities from the grid
