Asphalt is a commonly used high-viscosity organic chemical material. Asphalt is used in many fields. When asphalt is produced, a large amount of asphalt fumes containing fine tar particles are often produced due to heating. Flue gas contains carbocyclic hydrocarbons, cyclic hydrocarbon derivatives and various other compounds, which not only pollutes the atmospheric environment, but also harms human health.

Asphalt smoke pollution is mainly concentrated in the finished material loading area and when the asphalt mixture is unloaded. In order to prevent the asphalt smoke and dust generated in the loading area of the asphalt mixing station from endangering human health and polluting the surrounding environment, the flue gas purification device during asphalt processing and use has become increasingly important, and purification equipment must be used to effectively Contain and improve the air quality of the surrounding environment.
