This is a packed tower, with the gas outlet at the top. What is the structure of the part marked with a red circle?
I didn’t upload all the pictures; below the two sections of packing in the tower, and below the packing supports, there is one of these items in each case. I also guess it’s a demister, but demisters are usually installed at the gas outlet, and its shape doesn’t really resemble that of a demister either; I really don’t understand_(:з」∠)_
There’s also a return-type condenser directly connected to the tower, which isn’t shown, right? The area enclosed by the red circle in the diagram is the combined assembly of the inclined plate liquid collector and the liquid redistributor. Among them, the inclined plate type liquid collector is also known as the vane type liquid collector; examples include Sulzer’s SLF, SLR, and SLM models (each suitable for different tower diameter ranges).
Conduit groove. See the answer on floor 5 for details{:9027:}
This is a redistributor, an internal component that collects the liquid and then distributes it evenly downward through the tower
Regeneration tower outlet, liquid mist prevention device
It should be a liquid distributor; one can look at the top view or sectional views. In a packed tower, there is no overflow weir, and the liquid is distributed evenly through the distributor to facilitate gas-liquid exchange. It can be of the trough type or the tube type. If it is a defoaming device, its location should be near the gas phase outlet, and swirl plates are generally used.
