Translate skirt height and static seal in the blister
Thread Content
Regarding the dimensions of the bubble column in its design, there are terms such as skirt height and static seal; I’m not quite sure what the corresponding professional terms in Chinese are. When looking at Chinese documents on bubble column design, it’s unclear which part of the bubble column structure these terms refer to. Could you help translate this? Thank you.
Skirt height – Height of the skirt base. Static seal – Static sealant. A static seal is a seal that is created between two components that remain stable and immobile. It refers to a seal in which there is no relative movement during the operation of the bearing. Dynamic seal – Dynamic sealant. A dynamic seal is a seal that is created between two elements that move relative to each other during operation. It refers to a seal used between moving parts within a machine (or device).
A bubble column is also known as a bubble cap column or bubble head column. A type of tower equipment. It is commonly used to bring steam (or gas) into close contact with a liquid in order to facilitate mass transfer between them. The tower is equipped with multiple layers of horizontal trays, on which there are several short tubes through which steam (or gas) can pass. These tubes are covered with bubble caps having toothed edges or small grooves, and the tower is also fitted with overflow pipes. During operation, the liquid enters continuously from the upper part of the tower, flows down layer by layer through the overflow pipes, and accumulates in layers on each plate, thus forming a liquid seal ； Steam (or gas) enters from the bottom of the tower, is dispersed into small bubbles through the gaps or slots at the bottom of the bubble cap, thereby coming into full contact with the liquid; it then passes through the liquid layer to reach the surface, and rises to the upper tray. When the short tube is installed inside the tower, it is called an internal overflow type ； There are also those installed outside the tower, known as external overflow type. Bubble columns are widely used in distillation and gas absorption. The skirt height should be the height of the aforementioned short tube, serving as a static liquid seal for the liquid at the top of the tray. For discussion.
So, is the skirt height the height of H2 in the diagram (marked on the left side of the diagram), and is the static head the height of H3 in the diagram?

Additionally, \"those with short pipes installed inside the tower are called internal overflow type.\"； There are also those installed outside the tower, known as \"external overflow type.\" I’m not quite sure what this means; I don’t fully understand what it implies to have them installed inside or outside the tower. Could a friendly user please explain this in clearer terms?
Skirt height should be the height of the tower skirt base, and static seal should be H2
The skirt height should be the value of H3 in the diagram; the static seal represents the height of the liquid layer, which is not indicated in the diagram but is a parameter that must be taken into account in the design.
