NOUFERROUS METALLURGICAL EQUIPMENT

In recent years, the development of pressurized leaching hydrometallurgy engineering towards a larger scale has been hindered by the technological constraints brought about by the large-scale development of supporting equipment. In order to adapt to the large-scale development of the key core equipment of the pressure leaching process-the horizontal reactor, and better ensure the reliability and efficiency of the equipment during use, This article uses CFD fluid simulation software to study the flow field distribution and the relationship between agitator power consumption and aspect ratio of a 300 vertical horizontal reactor used in a certain project under different aspect ratios. Research has shown that increasing the aspect ratio appropriately is beneficial for improving the horizontal flow field characteristics, reducing the aspect ratio is beneficial for improving the vertical flow field characteristics, and reducing the aspect ratio is beneficial for reducing the stirring power. When the aspect ratio is set to 1.08 or 1.13, it can effectively improve the reaction efficiency in the horizontal reactor, reduce costs and system energy consumption.
