AI Technical Summary

Technical Problem

In the process of hydrometallurgical zinc production, the strong coupling and nonlinear correlation between processes make it difficult to monitor the concentration of key ions in real time and accurately, and the reaction process and optimization control are difficult. In addition, the industrial field data is multi-source, heterogeneous and high-noise, which increases the difficulty of accurate modeling and optimization decision-making.

Method used

A digital twin system for hydrometallurgical zinc refining based on multi-process collaborative simulation is constructed. Through a mechanism- and data-driven architecture, a basic model framework for each process is established. Online learning is performed using a Long Short-Term Memory (LSTM) network, combined with an intelligent decision engine based on multi-agent reinforcement learning, to achieve collaborative optimization between processes.

Benefits of technology

It realizes dynamic simulation and global optimization of the entire process of hydrometallurgical zinc smelting, supports autonomous collaborative decision-making of process operation parameters, improves production efficiency and control level, and reduces overall consumption.

Abstract

本发明公开了一种基于多工序协同仿真的湿法炼锌数字孪生系统构建方法。该方法首先构建耦合各工序机理与数据驱动的混合子模型,并通过标准化接口与虚拟缓冲机制将其联接为可交互的多工序协同数字孪生体;在此基础上,引入多智能体强化学习框架,将各工序模型定义为智能体,在多工序协同数字孪生体中训练其协同决策策略,以实现全流程生产指标的全局优化;最终,该系统支持实时监控、前瞻推演与人机协同决策,从而在虚拟空间中实现生产过程的仿真、预测与闭环优化,为湿法炼锌的提质增效与协同控制提供智能化支撑。
