Abstract

The invention provides a production system and a production method for producing copper sulfate by using a copper electrolysis waste liquid, wherein the production system adopts a three-effect evaporation concentration device to carry out evaporation concentration on the copper electrolysis waste liquid, the evaporation efficiency is high, the waste heat of secondary steam can be recycled, energycan be effectively saved, and consumption can be reduced; a crystallization tank, a stirring tank and a centrifuge are matched to carry out cooling crystallization and solid-liquid separation on the copper electrolysis waste liquid after evaporation concentration, and the prepared copper sulfate finished product can also be automatically weighed and packaged, so that the automation degree is high,the operation is simple, and the labor force is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of copper sulfate production, in particular to a production system and a production method for producing copper sulfate from copper electrolysis waste liquid. Background technique [0002] In the production process of copper smelting, with the progress of copper electrolysis, the efficiency of the anode is higher than that of the cathode, the concentration of Cu2+ continues to rise, and the impurities continue to accumulate. The use of waste electrolyte to produce copper sulfate is an important means to adjust the balance of copper-acid in the electrolyte. An important process for copper electrolytic purification. [0003] At present, electrolytic copper production enterprises mostly adopt the conventional production process of "conventional evaporation + cooling crystallization + solid-liquid separation" to process copper electrolyte and produce crystalline copper sulfate. At present, the production process...
