Rotary furnace for recycling used lead-acid batteries: Environmental protection technology helps write a new chapter in resource recycling

#Industry ·2026-05-27

In the era when modern industrial civilization and environmental protection are given equal importance, the harmless treatment and resource recovery of waste lead-acid batteries have become a global focusAs a core solution in this field, the rotary furnace technology is leading the wave of innovation in the resource recycling industry with its high efficiency, energy conservation, and environmental protection features.Innovative process, efficient recycling The rotary furnace adopts the principle of high-temperature smelting. By slowly rotating the furnace body, the materials are evenly heated, and the lead paste, grid plates, and plastic components are completely separatedIts unique temperature control system can precisely maintain the optimal reaction temperature of 1100°C to 1300°C, with a lead recovery rate of over 98%, far exceeding that of traditional processing methods.The fully enclosed design is more effective in preventing the escape of harmful gases and achieving clean productionEnvironmental advantages and dual protection Equipped with an advanced flue gas treatment system, the four-stage purification process of emergency cooling tower bag dust removal, activated carbon adsorption, and alkali solution spraying ensures that the emission concentrations of pollutants such as sulfur dioxide and lead dust are far below the national standardsFor every ton of waste batteries processed, about 3 tons of primary lead ore can be reduced, truly realizing the circular economy model of "turning waste into treasure".Intelligent control and stable operation Equipped with a PLC automatic control system, it monitors key parameters such as the furnace rotation speed, temperature curve, and oxygen content in real time.The modular design supports continuous operation for 72 hours without interruption, with a processing capacity of 10-15 tons per day, significantly enhancing the industrial scale benefitsThe application prospects are broad. At present, the technology has been successfully applied in several provincial hazardous waste disposal centers in Hunan, Jiangsu and other provinces, with a total processing volume of more than 500,000 tons.With the explosive growth of the new energy vehicle industry, this system will become an important infrastructure for ensuring the strategic security of lead resourcesThe rotary furnace technology not only solves the problem of heavy metal pollution, but also opens up a new paradigm for resource recyclingLet's join hands to promote green manufacturing, protect the green mountains and rivers with the power of technology, and build a sustainable and beautiful future together
