In the modern industrial circular economy system, the efficient disposal and resource utilization of waste lead-acid batteries have become an important issue in the field of environmental protection. Rotary furnace technology, as one of the core processes for handling waste lead-acid batteries, is driving the industry's transition towards green and low-carbon development with its unique advantages. The rotary furnace can effectively separate metal lead, plastic, and electrolyte components from lead-acid batteries through the high-temperature melting process. Its rotating design ensures uniform heating and complete reaction of materials, which not only significantly increases the lead recovery rate (up to over 98%) but also significantly reduces energy consumption and exhaust gas emissions. Combined with advanced exhaust gas treatment systems, it can effectively control the spread of pollutants such as sulfur dioxide, truly achieving clean production. In addition, this technology is both flexible and economical, and can adapt to different scales of recycling needs, helping enterprises reduce costs and increase efficiency. With increasingly stringent environmental protection policies and growing awareness of resource recycling, rotary furnace technology is bound to become an important engine for promoting the standardized disposal of waste lead-acid batteries, making a key contribution to building a sustainable future.
