Description

Technical Field

[0002] At present, the flue gas of most of the domestic power, steel, coking, and chemical industries is sprayed or wet desulfurized before being discharged, and the temperature is reduced to 45~55℃. At this time, the flue gas is usually saturated wet flue gas, which contains a large amount of water vapor, and the water vapor contains more soluble salts, SO3, gel dust, dust and other components that can form haze; if the flue gas is discharged directly from the chimney and enters the ambient air with a lower temperature, due to the low saturation humidity of the ambient air, during the process of reducing the flue gas temperature, the water vapor in the flue gas will condense to form colored plumes. In severe cases, colored plumes will also form "chimney rain" and "gypsum rain" within a certain range around the chimney. The more advanced process route for colored plume treatment in the world now is condensation first and then heating and heating. The condenser includes large-capacity condenser and ultra-large-capacity condenser.
