Regarding the design of concave liquid receiving trays
Thread Content
I currently have a tower with a diameter of around 9 meters, which uses four overflow devices, inclined downcomers, and a concave liquid receiving tray. What should be the depth of this liquid receiving tray when designing it? Also, must the bottom end of this downcomer extend deep into the liquid receiving tray? The height of the bottom gap in the downcomer refers to the height between the bottom end of the downcomer and the bottom end of the liquid receiving tray, or it refers to the height relative to the plane of the tray? What is the typical value for the bottom clearance height? Please give me some advice! I’m not very familiar with the actual engineering design parameters; thank you very much! ! !
For a 9-meter tower, it’s best to have professionals design it; asking questions like this is extremely irresponsible.
Of course, it’s definitely not for my own use; I just want to learn *a bit, haha~
For a 9m high overflow tower, truss beams are definitely necessary. The depth of the concave liquid receiving tray is usually 80-120, depending also on the board spacing. However, designing a concave liquid receiving tray with truss beams is still somewhat complicated. It’s not easy to adjust during installation. I don’t know what device it is? PX? The propylene column in the million-ton ethylene plant is also just over 7 meters tall.
Thank you! It is a atmospheric tower for vacuum distillation; there are now some examples of refineries with a capacity of tens of millions of tons, so the consideration is given to large-scale atmospheric towers, and 9 meters should still be feasible.
Take a look at some knowledge about towers: one is the low gap, and the other is the flow channel; there are two dimensions involved
We have produced three sets of 10 million tons each; now we are working on the fourth set
