摘要
对一个直径１０ｃｍ的滴流床反应器建立了一套压力在线测量系统。采样速度达到６８６次／秒，已经满足实际测量的需要。利用这一手段，对滴流床中存在的三种典型流型：滴流，过渡流和脉冲流进行了压力脉动测量，并报道了压力脉动数据的直方图分析和谱密度分析。
An on-line pressure measurement system was installed for a trickle-bed reactor with 10cm in diameter,the sampling speed was as fast as 686 times/sec which can fulfill the requirement of the practical need.With its help, the pressure pulsations of the three typical flow regimes existing in the bed which are trickling flow,transition flow and pulsing flow were measured.The pressure pulsation data were anaiyzcd by histogram and spectral density.
