Embodiment 1

[0119] This embodiment provides a device for real-time optimization of the rare earth extraction process, such as figure 2 As shown, the device includes a modeling module 1 for establishing a hybrid soft sensor model of the rare earth extraction and separation process. The modeling module 1 includes a mechanism modeling submodule and a support vector machine modeling submodule; a data module 2 for obtaining real-time data of the extraction and separation process; a model for evaluating and correcting the mixed soft sensor model established by the modeling module 1 Evaluation and correction module 3; construction of an optimization model of production parameters in the rare earth extraction process, and decision variable optimization module 4 for optimal solution. The data module 2 also includes a data processing sub-module for performing steady-state preprocessing on real-time data. The decision variable optimization module 4 includes an optimization model establishment subm...

Embodiment 2

[0228] This embodiment provides a method for real-time optimization of the rare earth extraction process. The method is the same as in Embodiment 1 except that the improved particle swarm optimization algorithm is replaced by the particle swarm optimization algorithm.

[0229] In Example 2, due to the use of the particle swarm optimization algorithm, compared with Example 1, it is still possible to achieve online prediction of component content and real-time optimization of key decision variables in the rare earth extraction and separation process, but the global convergence ability of the overall algorithm is relatively low. In the case of poor and single population, it has disadvantages such as easy to fall into local extremum and slow convergence speed.

[0230] In summary, the method for real-time optimization of the rare earth extraction process provided by the present invention realizes the online prediction of component content and the real-time optimization setting of k...

Abstract

The invention provides a real-time optimization method and device for a rare earth extraction process and a computer readable storage medium. The method comprises the following steps: constructing a mixed soft measurement model for the rare earth extraction process; acquiring real-time acquired data, and performing preprocessing and steady-state inspection; importing the processed real-time data into a mixed soft measurement model, and carrying out model performance evaluation and self-adaptive correction; establishing an extraction process real-time optimization model under constraint conditions by taking maximum economic benefits as a target and taking operation parameters as decision variables; and solving the optimization model to obtain an optimal control scheme. According to the method, optimal setting of the decision variables of the extraction device can be realized, so that the problems of high randomness of manual operation, high resource consumption and the like in the production process are solved, and real-time optimal operation of the extraction process is realized on the premise of ensuring stable production and meeting production index requirements, so that the purpose of maximizing the economic benefits of enterprises is achieved.

Description

technical field [0001] The invention relates to the technical field of optimization control of rare earth extraction and separation process, in particular to a method, device and computer-readable storage medium for real-time optimization of rare earth extraction process. Background technique [0002] Rare earths, as industrial "gold", are indispensable and important resources for the development of the world today. The rare earth extraction and separation process is a key process to realize the separation of rare earth elements, and the extraction effect directly determines the quality of rare earth products. [0003] At present, there is still a lot of room for improvement in the distribution characteristics of rare earth elements, the uniqueness of mineral structures, and related technologies. For example, most rare earth production enterprises still remain in the empirical operation mode of relying on off-line assays to analyze component content and manual adjustment of...
