摘　　要：对光热发电用有机热载体再生处理工艺进行系统建模、计算分析、优化,讨论再生处理效果的影响因素和控制要求,使用闪蒸分离和塔式分离进行高沸物和低沸物分离参比考察,确定再生处理的可行工艺路线,结果表明:闪蒸分离方式分离高沸物和低沸物在技术上是可行的,分离高沸物时,当分离罐(HB-S)温度控制在313℃时可满足要求,但低沸物分离效率偏低以及损耗偏大;采用分离塔分离低沸物时选择进料温度260℃,操作压力1bar,分离塔理论板数10块,回流比3的情况下低沸物回收率高,分离效果明显好于简单的闪蒸分离。The organic heat carrier regeneration treatment process for solar thermal power generation is systematically modeled,calculated,analyzed and optimized.The influencing factors and control requirements of the regeneration treatment effect are discussed.In order to determine the feasible process route of regeneration treatment,flash separation and tower separation were used to conduct a reference survey of high and low boiling matter separation.The results show that the separation of high and low boiling substances by flash separation is technically feasible.When separating high boiling matter,the temperature of the separation tank can be controlled at 313 ℃,but the separation efficiency of low boiling matter is low and the loss is large.When the separation column is used to separate the low boiling material,the low boiling material recovery rate is high and the separation effect is obviously better than that of simple flash separation under the conditions of feeding temperature 260 ℃,operating pressure 1 bar,10 theoretical plates of the separation tower,and return ratio of 3.
