Regarding the issue of water-gas blockage in the stripping tower, does anyone know how to solve it?
Thread Content
Our facility is equipped with a wastewater stripping unit designed for a capacity of 60 T/H; however, at present the amount of wastewater that needs to be treated is around 90–100 tons. As the air temperature rises in summer, the purified water drawn from the bottom of the stripping tower always creates an air blockage in front of the heat exchanger, resulting in poor flow of the purified water and making it difficult to maintain a stable liquid level in the stripping tower. How can this problem be solved? Note: The pressure at the top of the tower is around 0.55 Mpa; the purified water is drawn off at a level of about 0.60 above the tray level. The pressure at the bottom of the tower is around 0.62 Mpa, and the temperature at which the liquid is drawn off from the bottom of the tower is around 160°C.
Add a pump outlet to drive the heat exchanger and eliminate air resistance
Could a gas block be formed at the pump inlet?
It won’t happen; operating with air resistance is not good, and forced circulation is used to address that issue
A small amount of low-concentration fluid can be directly discharged through the drain strip pipe at the outlet of the heat exchanger, which helps to eliminate air blockages
