Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification devices, in particular to an asphalt waste gas purification device. Background Art

[0002] Asphalt is widely used in the industrial field. Asphalt will produce a large amount of flue gas in a short period of time during the heating process. The flue gas components are relatively complex, including solid and liquid particles condensed from the volatile components of asphalt, and organic matter in vapor state, which will cause a certain degree of pollution to the environment. The flue gas contains a variety of organic matter, including carbon ring hydrocarbons, cyclic hydrocarbon derivatives and other compounds. Many of them are harmful to human health. The main way they harm human health is to attach to floating dust below 8 um and be inhaled into the human body through the respiratory tract. At present, there are various asphalt smoke treatment devices on the market. Due to the high concentration of particulate matter and VOCs generated by asphalt smoke, the asphalt smoke purification equipment has high resistance, poor purification effect and high maintenance cost.
