Desulfurization tower inlet temperature
Thread Content
For desulfurization towers used in power plants, the inlet air temperature is around 120 degrees; does the spray circulation liquid system have a cooling mechanism? Looking at the pictures of the desulfurization tower, it seems there is no circulating water cooling; in that case, wouldn’t the temperature of the liquid circulating inside the tower keep rising? Please give me your advice
It’s hard to say just by looking at the process flow diagram
Water will evaporate and be carried away by the smoke gases, after which the demister is used to rinse and replenish water
Is the water that evaporates used to replenish water at the defogger location? Also, doesn’t the water circulating at the bottom of the tower absorb some of the heat from the flue gas?

Water cooling can be added in the middle depending on the gas temperature
The slurry inside the tower is in a state of dynamic equilibrium: the water evaporated from the slurry is carried away by the flue gas, and part of the slurry is also discharged; the demister wash water is used to replenish this water. The temperature of the slurry is generally around 50°C.
