摘　　要：基于放射性废液蒸发的特殊要求,设计了3 000 kg/h处理量的立式热虹吸式再沸器,分析了再沸器高径比对传热性能和流动特性的影响。结果表明：Kc和？pf随L/Di的增大近似呈线性上升的趋势,xE随L/Di的增大而先减小后增大,L/LBC随L/Di的增大则呈先增大后减小的趋势,L/Di值在2.4~2.7范围内较合理。A vertical thermosiphon rebniLer was designed based on evaporation.The in ucnces of height--diameter ratio on the heat analyzed.The results show that both of Kf and Apf almost increase increases,however,the tendency of L/LBC present the opposite case. the special requirements of 3000kg/h--scale radioactive waste liquid transfer performance and flow characteristics inside the reboiler were linearly with increasing L/Di.As L/Di incrcases,xE first decreases,then Reasonable L/Di, value of reboiler is between 2.4-2.7.
