Real-time optimization method and device for a rare earth extraction process and computer readable storage medium

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...
