In the process of exhausting flue gas into the atmosphere from a chimney port, due to temperature reduction, part of vaporous water and pollutants in the flue gas can be condensed, and further fog-like water vapor is formed at the chimney port, and the fog-like water vapor can be subjected to slight color change due to sky background color, sky illumination, observation angle and the like, so that colored smoke plume is formed. The "colored smoke plume" is usually white, and the "visual pollution" caused by the white smoke plume has become the focus of attention of the public. In addition, a large amount of water is taken away by wet flue gas, so that waste of water resources is caused, and therefore a key technology for removing and collecting water from flue gas is urgently needed.
