Lead-acid battery recycling not only effectively avoids the leakage of hazardous substances, but also recovers valuable materials such as lead, thus enabling the reuse of resources. To improve the recycling efficiency of lead-acid batteries, modern recycling equipment, especially cupola plays a crucial role in the lead-acid battery recycling process.

As a widely used metal smelting equipment, cupola is mainly used for lead refining and recycling in the process of lead-acid battery recycling. The role of the cupola is mainly reflected in:

Smelting of lead: the cupola heats the lead plates in the lead-acid batteries through high temperatures to extract the lead from other substances in the batteries.

Treatment of lead acid solution: lead-acid batteries contain a large amount of sulphuric acid solution, the cupola can not only effectively refine lead, but also deal with the lead acid solution in the smelting process to avoid its pollution of the environment.

Waste treatment: The residual materials in the recycling process need to be treated, and the cupola can effectively decompose and treat the waste battery shells and other materials that are not easy to recycle, reducing the burden on the environment.

Through the use of cupolas, lead and other metal components in lead-acid batteries can be efficiently recycled, thus reducing dependence on natural resources and minimizing the emission of hazardous substances.

The working principle of the cupola is based on the technology of pyrometallurgy. In the process of lead-acid battery recycling, the cupola smelts the lead in the used batteries at temperatures that can reach more than 1,000°C, which is enough to completely refine the lead in the lead-acid batteries. The specific steps are as follows:

Lead-acid battery placement: Firstly, the scrapped lead-acid batteries or the lead plates in them are put into the cupola furnace, and the temperature inside the furnace rises gradually.

Smelting process: At high temperatures, the lead in the lead-acid batteries is melted and separated from other impurities. This process can be accelerated by adjusting the flow of oxygen in the furnace.

Separation and collection of lead: During the smelting process, the lead is separated and collected into liquid lead through physicochemical reactions and operations inside the furnace, and finally it is collected through the lead liquid outlet.

In addition to the refining of lead, the cupola furnace is also capable of recovering other metals, such as copper and nickel, to further increase the recovery rate. By efficiently smelting lead from batteries, the cupola is able to ensure a high recovery rate while effectively reducing lead pollution.

Through the reasonable use of cupola and exhaust gas treatment equipment, the recovery of lead-acid batteries can not only achieve the recycling of resources but also effectively protect the environment and contribute to sustainable development. Therefore, promoting the continuous innovation and optimization of lead-acid battery recycling technology is an important measure to promote the green economy and environmental protection.
