Rotary furnace for recycling used lead-acid batteries: a technological tool for green recycling

#Industry ·2026-03-25

Today, with the rapid development of the environmental protection industry, the harmless treatment and resource recovery of waste lead-acid batteries have become a global focus of attention. The rotary furnace technology, as a core equipment in this field, is injecting strong impetus into resource recycling with its high efficiency, energy saving and environmental protection characteristics. 。 Core technical advantages The rotary furnace adopts a dynamic high-temperature roasting process, where materials are evenly heated by the slow rotation of the furnace body, effectively separating lead paste, grid plates and plastic components. Its closed design prevents the leakage of harmful gases, and combined with an advanced exhaust gas treatment system, it can achieve near-zero emissions of pollutants such as sulfur dioxide and lead dust. Compared with traditional reflective furnaces, the metal recovery rate is increased to more than 98%, and the energy consumption is reduced by more than 30%. 。 Circular economy value For every 10,000 tons of waste batteries processed, about 6,500 tons of recycled lead, 800 tons of plastic, and 2,000 tons of sodium sulfate by-products can be recovered, truly achieving the goal of "turning waste into treasure". This system not only alleviates the pressure of mining primary lead ore, but also builds a complete green industrial chain for lead-acid batteries from production, use to recycling through material closed-loop circulation. 。 Intelligent operation and maintenance system Modern rotary furnaces are equipped with an Internet of Things monitoring system, which tracks 18 key parameters such as furnace temperature, rotation speed, and oxygen concentration in real time. AI algorithms automatically optimize the combustion model, ensuring that the equipment always operates under optimal conditions. The remote diagnosis platform can warn of component wear and tear 14 days in advance, greatly improving the stability of continuous operation of the equipment. As a technical benchmark in the resource recycling industry, rotary furnace devices are replacing outdated production capacities worldwide. Its cross-disciplinary innovation integrating metallurgical engineering, environmental science, and intelligent control demonstrates the development wisdom of modern industry and ecological civilization coexistence, and provides an important technical support for the construction of waste-free cities.
