摘要
核设施产生的放射性废水中含有微小的固体悬浮物,收集废水的储槽在长期静置过程中,固体悬浮物会沉积在储槽底部。为避免接收放射性废液的储槽发生固体悬浮物沉积现象,本文通过设计合理的水力循环搅拌装置对废液储槽中的流体进行充分搅拌,以保证处理放射性废水时水中固体悬浮物分布均匀,不出现死角,同时采用CFD软件对水力循环搅拌装置进行数值模拟分析,并对废液储槽内搅拌效果进行分析评价,最终通过完工设备的试验验证模拟结果。
Radioactive waste water generated form nuclear facilities usually contain suspended solids. In the process of waste of waste water collection, suspended solid will be deposited at the bottom of the storage tank, therefore, in order to avoid this phenomenon, we should design hydraulic cycle stirring device to stir waste water in storage tank, and ensure the suspended solid to distribute evenly. In this paper, the author use the CFD software to simulation analysis the hydraulic cycle stirring device, and evaluate the effect of stirring, and verify the simulation results through the actual device.
