This invention discloses an intelligent simulation and computation method for complex chemical reactions. Combining multimodal data fusion, deep learning models, and physically constrained networks (PINNs), along with reinforcement learning optimization strategies, it achieves efficient and accurate prediction of reaction processes and intelligent control of reactor parameters. The method first constructs a reaction model using graph neural networks (GNNs) and physically constrained neural networks (PINNs), embedding core equations from chemical kinetics, mass transfer, and fluid dynamics to ensure the prediction results conform to physical laws. Then, based on the proximal strategy optimization (PPO) algorithm, it achieves real-time optimization of reaction conditions, dynamically adjusting operating parameters such as temperature, pressure, and flow rate to maximize reaction conversion, selectivity, and energy efficiency. This invention can be widely applied to chemical reaction systems such as catalytic reactions, multiphase reactors, microchannel reactors, and drug synthesis, significantly improving computational efficiency and accuracy, reducing the computation time of traditional methods, and providing intelligent online optimization and control solutions for industrial chemical reaction processes.
