The invention provides an intelligent autonomous control method and system for an impurity removal reactor in a zinc liquid purification process, and relates to the technical field of information processing. The invention adopts a hybrid model switching control method combining a model predictive control method and an adaptive dynamic programming method to optimize the concentration of impurity ions in a purification and impurity removal reactor, thereby improving control precision. At the same time, the invention solves the problem that the model parameters in the model predictive control are unknown in the traditional manual setting control method due to the disturbance of the feed condition, the change of the working condition or the jump to a different working condition, which leads to the decline of the control performance, and realizes fast , to accurately realize the intelligent autonomous control of the concentration of impurity ions in the impurity removal reactor.
Description
technical field [0001] The invention relates to the technical field of information processing, in particular to an intelligent autonomous control method and system for an impurity removal reactor in a zinc liquid purification process. Background technique [0002] Zinc hydrometallurgy refers to the process of dissolving zinc in zinc calcine or other zinc sulfide materials and zinc sulfide concentrate in an aqueous solution, and then extracting metal zinc or zinc compounds from it by zinc electrowinning, which is the main process of modern zinc smelting. method. In order to meet the requirements of zinc electrowinning, it is necessary to purify various impurity ions in the zinc sulfate leaching solution to below the specified standard. It is difficult to remove these metal impurity ions, and at the same time, it has a great influence on the current efficiency of the electrolysis process. Therefore, in actual production, the purification effect of the entire purification pro...
