Difference between liquid receiving disk and liquid sealing disk
Thread Content
What is the difference between a tower’s liquid receiving tray and its liquid seal tray? Is it due to different functions, or are there other reasons?
The part of the tray that receives the liquid flowing down from the previous tray is called the liquid receiving tray. The liquid receiving trays come in two types: concave and flat. Flat liquid receiving trays generally require an inlet weir to be installed on the tray, in order to ensure a liquid seal in the downcomer and to enable even distribution of the liquid across the tray. Installing an inlet weir not only takes up space on the plate surface but also tends to cause sediment to accumulate there, leading to blockages. The use of a concave liquid receiving tray eliminates the need for an inlet weir. The concave liquid receiving tray not only creates an effective liquid seal when the liquid level is low, but also serves as a buffer to change the direction of the liquid flow, facilitating its extraction via side lines. The liquid seal tray is generally located directly below the downcomer, where it gathers the liquid to maintain a uniform liquid level and effective seal. That’s all I can remember from what I learned before. I’ll bring my books back when I get there, and then I can answer you more specifically
The liquid seal plate is the smallest component at the end of the tray, acting as the final liquid-receiving plate
The liquid receiving tray is often part of the tray； The liquid seal disk is located below the downcomer to prevent gas short-circuiting, and it is used less frequently.
The bottommost piece is called the liquid seal disk, while the others are called liquid receiving disks. The liquid seal disc seals the gas path. Let the gas flow vertically through the distillation tray.
