Description

Technical Field

[0002] Flue gas from waste liquid incineration is discharged through the chimney. It is rapidly cooled by the low-temperature atmosphere, and the water vapor in the flue gas condenses into liquid. The light transmittance of the flue gas decreases, forming a white plume, which shows the phenomenon of white smoke coming out of the chimney. Flue gas also contains nitrogen oxides, sulfides, various smoke particles, aerosols, and various crystalline salt particles, which will pollute the atmospheric environment. Therefore, flue gas de-whitening is not only to eliminate visual pollution, but also to eliminate harmful substances in the flue gas more thoroughly.
