摘　　要：冷冻脱硅氧烷系统从开机到进入稳定运行状态存在一个较长的非稳态缓冲时间段,这个过程降低了系统的脱硅氧烷处理效率和系统稳定性。这篇论文通过两组对比实验,拟合出在缓冲时间段内两组蒸发器进、出口温度随时间变化的函数,探讨了预冷器蒸发器之间的耦合关系和自身热惰性的影响因素,以及这两个问题对非稳态缓冲期的影响结果。Cryogenic siloxane removal system need a long unsteady buffering time from starting up state to stable operation state, this situation greatly reduced efficiency and stability of Cryogenic siloxane removal system. Two functions about evaporator temperature variation with time were got by the two groups of contrast test, which can be used in unsteady buffering time. It is concluded that the main reasons leading to a long unsteady buffering time were the thermal inertia of precooler and evaporator and the coupling relationship of them.
