Description
Spent lead-acid batteries generally come from scrapped cars and electric bicycles, and lead-acid batteries can be divided into starting (liquid-rich) lead-acid batteries, power (liquid-lean) lead-acid batteries, and other types according to the difference in structure and use. Spent lead-acid batteries contain 11%~30% (mass) electrolyte.
In the dismantling stage, the outflow of electro-liquid is sealed and stored, and the neutralization tank is regularly pumped into the neutralization tank, sodium carbonate and other agents are added, and anhydrous sodium sulfate is produced through processes such as filtration and centrifugation.
Activity Description
This dataset represents the treatment process of the electrolyte discharged during the disassembly phase, including energy and auxiliary material consumption, wastewater discharge, and waste generation.
Process Description
Collect the electrolyte discharged during the disassembly of waste lead-acid batteries and carry out neutralization treatment.
