Sugarcane sugar boiling equipment optimizing design modeling and modeling method based on field synergy principle

Abstract

The invention provides a sugarcane sugar boiling equipment optimizing design modeling and modeling method based on the field synergy principle. The modeling comprises a subsystem analysis model, a subsystem optimization model and a system optimization model. The subsystem analysis model is used for analyzing a single physical field to form a module with certain functions; the module comprises field analysis, field coupling interface analysis, field coupling coordination variables and numerical simulation analysis. The subsystem optimization model is used for analyzing two different physical field coupling coordination in the subsystem analysis model; the target function is a minimized optimized function of the difference between coupling variables and shared variables, and constraint condition is the constraint of the system; the system optimization model is used for overall coordinating the system with a plurality of physical fields for boiling sugar coordinately, and constraint condition is consistent constraints of the coupling variables and shared variables of each subsystem. By the aid of the modeling method, structure, parameters and operating parameters of the batch-type sugar boiling equipment can be designed optimally, quantity of sugar is increased, quality of sugar is improved, sugar boiling time is shortened, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of design optimization of intermittent sugarcane sugar boiling equipment, in particular to a modeling and modeling method for optimal design of sugarcane sugar boiling equipment based on the principle of field synergy. Background technique [0002] China is a big sugar producing country, and its sugar production ranks among the top in the world. In sugar-producing countries in developed foreign regions, such as Denmark, the United States, Australia and other countries, the sugar-making enterprises have advanced equipment technology and production technology, while my country's sugar-making enterprises are small in scale and backward in production technology. Most of the sugar production equipment is outdated and the technical level low. However, the investment in purchasing imported equipment is huge, and the only way out is to independently research and develop sugar production technology and equipment to improve pro...

However, since the flow of massecuite in the process of boiling sugar is a high-viscosity gas, liquid and solid multiphase flow, the information contained has various modes such as qualitative, quantitative, and semi-quantitative, and the dynamic characteristics of the massecuite circulation flow show great The randomness of the process is closely related to the type of sugar pot, the mechanical structure of the cycle, and the physical properties of the massecuite, and it changes with time and the operating parameters of the sugar cooking process. It is a very complex thermodynamic system.
