摘　　要：为了提升碘吸附器在生产及应用过程中性能检测的安全性、适用性和自动化程度,以气流闭式循环设计、精准自调控技术为突破,研制出具有多功能特点的自动化循环式碘吸附器性能检测系统装置,对装置的密封性及运行稳定性进行了测试,过滤部件及系统的密封性均满足相关标准要求;装置可实现运行风量400-1400m3/h范围内任意设定值下的精确调节控制,且气流参数控制精度高、稳定性好,可实现1200m3/h风量连续循环运行24h风量变化小于3.75%,露点温度差最大不超过0.75℃,提升了实验及产品检测的准确性和安全性。在开放工况和循环工况下分别进行机械泄漏率和吸附放射性甲基碘效率试验,结果具有一致性和稳定性。In order to improve the automation, applicability and safety of performance testing of iodine adsorber in the production and application process, closed-cycle design and precise self-regulation technology were taken as breakthroughs, and an automatic circulating performance testing system with multi-functional characteristics of iodine adsorber has been developed. The sealing and operation stability of the device have been tested, which met the requirements of relevant qualification standards. The device can realize the adjustment and control of the operating air volume in the range of 400-1400m3/h, which has high control accuracy and good stability of air flow parameters. The change of air volume was less than 3.75% during 24h continuous circulation operation at 1200m3/h, and the maximum dew-point temperature difference was not more than 0.75℃, which improved the accuracy and safety of experiment and product testing. Mechanical leakage rate and adsorption efficiency of radioactive methyl iodine were tested under open and cyclic conditions respectively, and the results were consistent and stable.
