This study targets the control of typical and bulk lead-based solid waste pollutants and the resource utilization of waste residues, and conducts research on the basic properties of raw materials including lead paste, zinc hydrometallurgy leaching residue, slag-making flux limestone, and typical side-blown smelting reduction slag. Based on the optimized slag composition obtained from the co-smelting material composition and the thermodynamic properties of slag viscosity, the law of lead-based solid waste co-smelting process was investigated using computational fluid dynamics (CFD)-based numerical simulation methods, and a stable control scheme for enhanced smelting parameters of side-top blowing furnaces was proposed. Aiming at the efficient utilization of flue gas waste heat, the changes of flow field and thermal field inside the flue duct were simulated and analyzed, the spin-condensation heat transfer technology for high-temperature flue gas dust and slag and the flue gas waste heat utilization technology using energy storage materials were studied, and solutions to problems such as low heat transfer efficiency caused by flue deposition of high-temperature flue gas dust and slag and ineffective loss of high-temperature and low-temperature flue gas waste heat were put forward. Focusing on the suppression and resourceful transformation of flue gas pollutants and the harmless treatment of waste residues, in-situ control methods for gaseous pollutants including dioxins, SO₂ and NOₓ during the smelting process were researched. The design drawings of oxygen lance with a service life of more than 6 months and design documents of refractory lining with a service life of more than 12 months were developed. A complete set of enhanced side-top blowing smelting equipment for typical and bulk lead-based solid waste co-smelting with an annual processing capacity of 200,000 tons was successfully developed and applied as a demonstration project. Based on the final research results, the basic properties of typical and bulk lead-based solid waste co-smelting raw materials and the law of smelting process were clarified, the slag type of smelting slag was optimized, the variation laws of pressure field and temperature field around the oxygen lance were obtained, the in-situ control methods for flue gas pollutants such as dioxins during the smelting process and flue gas waste heat utilization technologies were proposed, and the research and development of key equipment for typical and bulk lead-based solid waste co-smelting and the demonstration project were successfully carried out.
