Spending smaller and drop has time enough sedimentation；Therefore, the present invention recommends the caliber of liquid phase bottom pipe 7 to be managed for 1.5 times of the pipe 5 that has a down dip
Footpath, while expansion tube 6 produces injection effect, drop hits wall deposition；The minimum of the entrance of liquid phase bottom pipe 7 to the bottom of standpipe 9 is long
Degree passes through superficial gas velocity in water-drop sedimentation velocity formula combination liquid phase bottom pipe 7 and determined.
5) standpipe 9 is the passage of the liquid phase of gas phase push pipe 3 and the gas phase swapace of liquid phase bottom pipe 7, should ensure that droplet settling speed
Degree is more than the average gas velocity in the section of standpipe 9, therefore can be solved with the superficial gas velocity of standpipe 9 by simultaneous water-drop sedimentation velocity formula
Obtain the minimum value of the caliber of standpipe 9；When standpipe 9 is not completely filled with by the liquid in liquid phase bottom pipe 7, it is believed that standpipe 9 can be just
Often work, therefore, the pressure transient equation arrived by Bernoulli equation and liquid plug can solve liquid phase can reach in standpipe 9
The maximum height arrived, the minimum value of the height of standpipe 9 is highly used as using this.
6) length of separator other parts component can be obtained according to geometrical relationship computing.
