Abstract:The synergistic smelting process for lead-based solid waste with multiple metals is of great significance to achieving green treatment and efficient recovery, avoiding environmental pollution, and promoting carbon peaking and carbon neutrality. The efficient monitoring and intelligent warning system adopts the technology of integrating digital mechanism modelling and digital simulation modelling. Not only the complex mechanism model containing feed decomposition, element distribution and product coalescence is constructed, but also the three-dimensional production scene for continuous smelting process of lead-based solid waste is built. It intuitively and realistically displays the workshop building structure, production equipment attribute and dynamic production process, achieving digitalization and visualization of the entire smelting process. Moreover, through production data monitoring with the coupling analysis of mechanism models, as well as the warning analysis for equipment key parameter and on-site personnel safety, process personnel can understand any production details in real time, make more scientific and efficient decisions, and ensure the safe and stable operation of the production process.
