Description

Technical Field

[0001] The utility model relates to the technical field of asphalt tail gas treatment, in particular to an asphalt production tail gas treatment device. Background Art

[0002] The asphalt production process produces exhaust gas, most of which is air, but it contains harmful substances such as sulfur dioxide, nitrogen oxides and benzopyrene. Asphalt production exhaust gas treatment is an important environmental protection measure aimed at reducing the impact of harmful fumes generated during asphalt production and use on the environment and human health.

[0003] If the exhaust gas generated during the asphalt production process is discharged directly, it will form industrial smog, which will make people breathe difficult at high concentrations. After entering the atmosphere, it will form acid rain, which is harmful to buildings, forests, lakes, and soil. It will also form suspended particulate matter, also known as aerosols, which enter the lungs with people's breathing and cause damage. The existing asphalt exhaust treatment device concentrates the exhaust treatment in an exhaust treatment box and adds an alkali liquid tank to purify the exhaust gas. However, the asphalt exhaust contains many difficult-to-decompose organic compounds. Using only alkali liquid for treatment cannot completely eliminate harmful substances. At the same time, it is difficult to handle and replace the alkali liquid, and it will cause frequent maintenance and high repair costs. Utility Model Content
