Abstract:

The liquid lithium-lead alloy bubbler is a very important composition in the tritium unit of Chinese Dual-Functional Lithium Lead Test Blanket Module (DFLL-TBM). In order to complete the construction and run of the bubbler experimental system, overall design of the system, main circuit design and auxiliary system design have been proposed on the basis of theoretical calculations for the interaction of hydrogen isotope with lithium-lead alloy and experiment for hydrogen extraction from liquid lithium-lead alloy by bubbling with rotational jet nozzle. The key of this design is gas-liquid exchange packed column, to achieve the measurement and extraction of hydrogen isotopes from liquid lithium-lead alloy.

Key words: Lithium-lead alloy, Bubbler, Design, Hydrogen isotope

摘要：

液态锂铅合金鼓泡器是中国双功能液态锂铅测试包层氚处理单元的重要组成部分。为了完成鼓泡器实验系统的建造与运行，在多年开展氢同位素与锂铅合金相互作用的理论计算和旋转喷嘴鼓泡法提取液态锂铅中微量氢实验的基础上，提出了实验系统的总体设计、主回路设计和辅助系统设计。这个设计以气液交换填料塔为核心，实现了液态锂铅中氢同位素的测量与提取。
