What is the function of the liquid seal device at the bottom of a packed absorption tower?
The function of a liquid seal is generally to stabilize the gas pressure inside the column.
Maintain a certain amount of liquid at the bottom of the absorption tower to prevent the gas from flowing through empty space.
A liquid seal refers to the use of a liquid to create a seal. General liquid seals are suitable for situations where the pressure difference between the inside and outside of the area to be sealed is not very large (such as in laboratories where oxygen is produced from hydrogen peroxide), as well as in places where high sealing standards are required or where it is not convenient to install valves. The medium used for liquid sealing is generally required not to react with the gas being sealed, and water or oil is commonly used. There are also examples of liquid seals in everyday life; you can take a look – in the kitchens or bathrooms of your home, there is usually a pipe that makes an S-shaped bend below the sink, and this too is a type of liquid seal that prevents odors from escaping from the sewer system.
Prevent gas from escaping. Air flow in the stabilizer tower.
Maintain the liquid level inside the tower to prevent gas leakage
Stabilize the pressure in the stabilizer tower to prevent gases from entering processes where they are not supposed to be
Maintain the liquid level inside the tower, prevent gas leakage, and keep the pressure within the tower at an appropriate level
If there is no liquid seal device, air will leak out directly from the bottom of the tower~! With a liquid seal device, it is possible to create a barrier that seals off the gas, thereby maintaining the pressure inside the tower
The liquid seal at the bottom of the tower is primarily used to prevent the escape of gaseous substances from within the tower and to maintain a stable operating pressure there; generally, the height of the liquid in this seal needs to be kept at a certain level!
Prevent gas short-circuiting and flowing out from the bottom of the tower.
