一、概述沸腾床催化反应器内催化剂的料位测量,往往是由两台差压计的输出信号作除法运算后间接获取。如图一所示,差压计 pd_1测取值 pD_1为容器底部承受的催化剂静压强,该差压计上、下两取压咀应分别设在容器底部和上部,并且保证上取压咀的位置高 First, an overview Ebullated bed catalytic reactor catalyst level measurement, often by the two differential pressure gauge output signal for indirect division. As shown in Figure 1, pd_1 differential pressure gauge pD_1 for the bottom of the container to withstand the static pressure of the catalyst, the pressure gauge on the next two pressure Tsui should be set at the bottom and top of the container, respectively, and ensure that the pressure on the nozzle High position
