摘　　要：为满足受限空间或小风量核设施通风系统对碘吸附器的需要,设计了一种椭圆结构的碘吸附器。针对该碘吸附器进行了内部流场模拟分析和整机性能测试。试验结果表明:碘吸附器内部气流分布均匀,结构设计合理,体积小、重量轻、与系统连接方便快捷,在300 m^(3)/h流量下阻力小于300 Pa,机械泄漏率小于0.01%,放射性甲基碘吸附效率大于99.99%,总体满足核设施通风系统中碘吸附器放射性碘的净化处理需求,并实现了工程应用。In order to meet the needs of iodine adsorber in the ventilation system of nuclear facilities with confined space or small air flow rate,an elliptical iodine adsorber was designed.The internal flow field simulation analysis and overall performance test of the iodine adsorber were carried out.The experimental results show that the internal air flow distribution in the iodine adsorber is uniform,the structural design is reasonable,the volume is small,the weight is light,and the connection with the system is convenient and fast.Under the flow rate of 300 m^(3)/h,the resistance is less than 300 Pa,the mechanical leakage rate is less than 0.01%,and the adsorption efficiency of the adsorber of radioactive methyl iodine is more than 99.99%.It generally meets the purification and treatment requirements of specified application of nuclear facility,and the engineering application is realized.
