The function of the water seal in a saturated hot water tower
The shifted gas entering the hot water tower has a temperature of around 160 degrees and contains a large amount of steam, which is used to recover heat within the hot water tower. The hot water, after having its heat recovered, flows into the saturation tower via a water seal to saturate the semi-water gas. The function of the water seal is to prevent semi-water gas from mixing into the shift gas when the liquid level in the hot water tower is too low, thereby avoiding an increase in the oxygen content in the shift gas.
Prevent semi-water gas from leaking into the shift gas, which could cause an increase in carbon monoxide levels in the shift gas and lead to a slight rise.
The function of the conversion water seal is to prevent air from passing between the inlet and outlet in the conversion system due to pressure differences, which could otherwise cause an increase in the level of CO at the outlet.
In addition to preventing air from entering, the function of the water seal in a saturated hot water tower is, in my opinion, to help regulate flow when there is steam resistance or when the liquid level in the hot water tower is too high, making it difficult to lower the liquid level in the saturated tower. Another point is that the hot water pump can also cause air to enter the saturated hot water tower

Actually. The circulating hot water seal between the saturated tower and the hot water tower was a design feature from times when automatic control capabilities were limited; under today’s automated control conditions, it should be possible to eliminate this seal tube by using automatic control to stabilize the liquid level at the bottom of the saturated tower.
