Abstract

The invention relates to the technical field of nonferrous metallurgy and provides a measurement method and system for an electrolysis condition in a zinc electrolysis process. The method comprises the steps of building a mathematic model of the zinc electrolysis process according to a flow state characteristic of an electrolytic solution in an electrolytic bath and an electrolytic characteristic corresponding to an electrolytic reaction system in the electrolytic bath in the zinc electrolysis process; building a physical model corresponding to the electrolytic bath in an equal-ratio manner; and performing simulation on the zinc electrolysis process in the electrolytic bath according to the mathematic model and the physical model to obtain condition parameters which represent the electrolysis condition of the zinc electrolysis process. According to the measurement method and system for the electrolysis condition in the zinc electrolysis process, provided by the invention, the condition state of the zinc electrolysis process is obtained through modeling and simulation of the zinc electrolysis process, so that the convenience can be provided for optimization control of the zinc electrolysis process, the time is shortened, and the overall efficiency is improved; and meanwhile, a test does not need to be carried out, so that the method is more economic and more flexible in comparison with a conventional method.

Description

technical field

[0001] The invention relates to the technical field of nonferrous metallurgy, and more specifically, to a method and system for measuring electrolysis working conditions in the process of zinc electrolysis. Background technique

[0002] Hydrometallurgy is the main method of zinc smelting, and more than 85% of zinc in the world is produced through hydrometallurgy. Electrolysis is the largest energy-consuming process in the zinc hydrometallurgy process, and its electricity consumption accounts for more than 95% of the total electricity consumption in the hydrometallurgy zinc smelting process, and the electricity cost accounts for 30%-40% of the processing cost. Therefore, the energy saving and consumption reduction in the electrolysis process is of great significance to realize the green production of zinc hydrometallurgy.

[0003] In the process of zinc electrolysis, process parameters such as the acid / zinc ion concentration of the electrolyte and the current...
