Embodiment Construction
[0078] The hierarchical optimization control method for the whole process of hydrometallurgy is characterized in that under the condition that the production management department determines the total output and total consumption, the optimization control problem of the whole process is divided into two parts: process-level index optimization and process-level loop setting optimization. To realize the multi-level structure, that is, firstly optimize the indicators of each key production process, and then realize the optimization of the key control loop setting of each process on the basis of the optimization results of the process indicators; The correlation model of each process index, with the goal of maximizing the economic benefits of the whole process, takes the process index as the decision variable, establishes the process index optimization model to realize the process index optimization; on the basis of the process model of each process, introduces the process index opt...

The invention provides a layered optimization control technology for the whole process of hydrometallurgy. Under the condition that the production management department determines the total output and total consumption, the optimization control problem of the whole process is divided into process-level index optimization and process-level loop setting optimization. A two-tier structure is implemented. First of all, by establishing the correlation model of each process index that describes the relationship between the output and minimum consumption of each process in hydrometallurgy, and then, on the basis of each process model, establish a process optimization model and solve it, and then realize the design of key control loops. set optimization. The present invention also provides a software system for implementing the above-mentioned whole process optimization control technology, which includes a main program, a database and an interface. The invention is applied to a hydrometallurgical production process, which reduces production costs and improves economic benefits.
Description
technical field [0001] The invention belongs to the field of hydrometallurgy, and proposes a layered optimization control method for the entire process of hydrometallurgy, and further provides a layered optimization control technology for the entire process of hydrometallurgy. Background technique [0002] Hydrometallurgy has the advantages of high efficiency, cleanness, and is suitable for the recovery of low-grade complex metal mineral resources. It is especially suitable for the characteristics of my country's mineral resources, which are rich in lean ore, complex symbiosis, and high impurity content. It is of great significance to improve the comprehensive utilization rate, reduce the output of solid waste, and reduce environmental pollution. [0003] In recent years, research on hydrometallurgical technology and equipment has progressed rapidly. However, the hydrometallurgical process is complex, with various types of equipment and harsh process conditions, such as high...
