摘要
近年来,加压浸出湿法冶金工程在向更大规模的发展道路受到了配套装备大型化带来的技术制约。为了适应加压浸出工艺关键核心设备-卧式反应釜的规模大型化发展,更好地保证该设备在使用过程中的可靠性与高效性。本文采用CFD流体模拟软件,针对某项目使用的300立卧式反应釜,研究其在不同长径比下的流场分布情况以及搅拌器功率消耗大小与长径比的关系。研究表明适当增加长径比有利于改善水平方向的流场特性,减小长径比有利于改善垂直方向的流场特性,减小长径比有利于搅拌功率的降低。当长径比取1.08或1.13,能够有效提高卧式反应釜内的反应效率,降低成本和系统能耗。
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.
