Description

Technical Field

[0001] The utility model relates to the technical field of flue gas pretreatment, and more specifically, to a flue gas pretreatment device. Background Art

[0002] In the processes of steelmaking in daily life, chemical product processing, and garbage incineration in garbage disposal, a large amount of flue gas is often generated. These flue gases contain a large amount of harmful substances such as smoke and dust, which will cause serious damage to the environment. Therefore, they need to be treated to meet the standards before they can be discharged.

[0003] In the existing technology, it is not convenient to adjust the flue gas circulation speed according to the progress of flue gas treatment. If the flue gas flow rate is too fast, the contact time between the gas and the purifier is insufficient, resulting in reduced pollutant removal efficiency. Conversely, if the flow rate is too slow, it will increase energy consumption and reduce the overall efficiency of the treatment system. At the same time, when the smoke in the flue gas is adsorbed by activated carbon rods, the adsorption efficiency of the stationary activated carbon rods is limited and needs to be cleaned frequently, which reduces the flue gas treatment efficiency.
