Urgent help needed regarding tower top deflection control issue
Thread Content
Gentlemen: There is a packing tower with a diameter of DN600 and a height of 30m; the HG Code for Tower Design specifies DN
Only adding a framework can solve this problem. Refer to JB/T4710-2005 Steel Tower Containers for details.
I believe that for a packed tower, a deflection control of H/100 is just right. With a length-to-diameter ratio of 50, if H/100 is to be maintained, the wall thickness of the tower shell or the skirt will likely need to be quite large, which may not be very suitable. Because the deflection is proportional to the fourth power of the tower height H, and inversely proportional to the cube of the tower radius R. Generally, the height of the tower cannot be reduced (as the theoretical number of theoretical plates required in the process cannot be decreased); therefore, the tower diameter is usually increased to reduce its deflection, and calculations show that the wall thickness of the tower shell can then be made more appropriate.
If the tower diameter and height are not to be changed, tower hoops can only be installed at appropriate positions on the frame to transfer part of the load to the frame
