The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. During the use of the boiler, flue gas will be generated. Since the flue gas has a certain temperature and humidity, when the flue gas directly contacts the low-temperature air, it will condense into small water droplets, thus forming wet flue gas.

[0003] In order to make the flue gas emitted by the boiler more in line with environmental requirements, it is necessary to use the corresponding boiler flue gas de-whitening device. During the process of de-whitening the flue gas, some common boiler flue gas de-whitening devices mostly change the temperature of the flue gas to avoid contact and condensation between the flue gas and the air, thereby performing de-whitening treatment. However, some common boiler flue gas de-whitening devices cannot filter some smoke dust in the flue gas very well.

[0004] Therefore, it is necessary to provide a boiler flue gas whitening device to solve the above technical problems. Utility Model Content
