【摘要】 针对氚工艺尾气处理的需求和源项实际情况,根据化工原理和氚的特性进行了含自动控制功能除氚系统的主要部件设计、自动控制功能设计和初步性能测试,得出了催化反应器、氚水吸附床等部件的结构尺寸,催化剂、干燥吸附剂的装填量等参数及控制软件界面;通过除氘和除氚实验初步测试了除氚系统的处理性能。结果表明,在循环处理模式下,对于1m3密闭容器中,氘体积比为6.0×10-4～2.8×10-2范围内时,35min内氘气浓度降低两个量级;通过5次对30L密闭容器内不同浓度的含氚气体进行处理,在60min内对氚的去除效率均达到了95%以上,除氚效果良好,符合设计指标,满足氚工艺的除氚要求。更多还原

【Abstract】 In order to remove waste tritium permeated from source item, autocontrol de-tritium gas system was designed according to demand and action of removing waste tritium gas from inflating tritium process,and the data of character and volumn about appliance of catalyst reaction and drying agend was calculated,the function of autocontrol software was designed also. Through the circulating disposal model test,it was result that in 1m3 closed container,deuterium consistency reduced 2 magnitude in 35min,and de-tritium system’s efficiency reached above 95% average to tritium in 30L closed container, so that the detritium system can be used in practice extensively.更多还原
