When the saturated wet flue gas discharged from the chimney during production comes into contact with the ambient air with a lower temperature, during the cooling process of the flue gas, the water vapor contained in the flue gas is supersaturated and condensed, and the condensed water droplets refract and scatter the light, thereby causing the plume Showing white or gray, called "white smoke".

It is mainly to heat the condensed unsaturated flue gas with the heat of the high-temperature flue gas in the production process through the heat absorbed by the heat exchanger, condense the flue gas when the saturated wet flue gas is at a low temperature, and separate out the flue gas. Most of the moisture and pollutants in the air, and then the condensed low-temperature flue gas is heated to turn the original saturated flue gas into unsaturated flue gas. At the same time, it can improve the water and electricity consumption of the original system, improve the stable and efficient operation of the original system, and reduce energy consumption.

Advantages of de-whitening technology

1. Adjust the outlet temperature of the heat exchanger according to the operating load
2. Adjust the physical and chemical environment of flue gas to ensure that the system does not scale or block ash
3. Ensure the water balance and heat balance of the system
4. The modular design of the unit is convenient for installation and maintenance
5. Good condensation effect and low investment cost
6. Reasonable design, scientific flow field, low operating cost and high system stability
