Rotary furnace for recycling used lead-acid batteries: a key technology for environmental protection and resource recycling

#Industry ·2026-04-06

Under the background of the circular economy and green development, the harmless treatment and resource recovery of used lead-acid batteries have become a global focus of attention. Rotary furnace technology, as the core process for treating used lead-acid batteries, is injecting strong momentum into sustainable development with its high efficiency, environmental protection, and resource utilization characteristics. I. What is rotary furnace technology? A rotary furnace is a device used to treat hazardous waste through high-temperature pyrolysis. Its main component is a tilted, rotatable furnace body. Through the coordinated operation of the temperature control system, exhaust gas treatment system, and automatic feeding and discharging devices, it achieves efficient separation and recovery of valuable metals (such as lead and antimony) from used lead-acid batteries, while ensuring the safe disposal of hazardous substances (such as acid solution and plastics). II. Technical Advantages and Highlights 1. High resource recovery rate: The lead recovery rate can reach over 98%, far exceeding that of traditional treatment methods; 2. Strong environmental compliance: Integrated exhaust gas purification systems effectively control the emissions of pollutants such as dioxins and sulfur oxides; 3. High energy utilization efficiency: Waste heat recovery technology significantly reduces energy consumption, meeting the requirements of low-carbon and circular development; 4. High degree of automation: Reduces the risk of manual operation and improves processing efficiency and safety. III. Application Value and Industry Significance This technology not only solves the hidden danger of used lead-acid batteries polluting soil and water, but also converts waste resources into high-purity lead ingots, plastic pellets, and other industrial raw materials, truly achieving "turning waste into treasure". At present, it has become a core equipment choice for battery recycling enterprises and environmental technology companies, helping to build a closed-loop industrial chain of "battery production - use - recycling - regeneration". Conclusion Rotary furnace technology is not only a practitioner of environmental responsibility, but also a driver of the resource revolution. With the dual tracks of technological innovation and policy support, this process will continue to provide solid support for global green transformation, allowing used batteries to be given a new life and contributing to the harmonious coexistence of humans and nature. --- *Note: The content of this article is based on general technical knowledge.
