Abstract

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. According to the invention, a mixed model switching control method combining a model prediction control method and an adaptive dynamic programming method is adopted to carry out optimal control on the impurity ion concentration of the purification and impurity removal reactor, so that the control precision is improved. The problem that the control performance is reduced due to unknown model parameters in model prediction control caused by disturbance of feeding conditions, change of working conditions or jumping to different working conditions in a traditional manual setting control method is solved, and intelligent autonomous control over the impurity ion concentration in the impurity removal reactor is achieved rapidly and accurately.

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...
