Description

Technical Field

[0001] The utility model relates to the technical field of asphalt filtering, and more specifically to an asphalt regeneration multiple filtering device. Background Art

[0002] The regeneration of asphalt is the reverse process of aging. Usually, regeneration agents can be added, such as corn oil, lubricating oil, etc. After adding the regeneration agent, the relative content of asphaltene is reduced, and the solubility of soft asphaltene to asphaltene is improved, the compatibility of asphalt is improved, the penetration and ductility of asphalt are improved, and the performance is restored or close to the original performance. At present, a large amount of harmful gases will be generated during asphalt regeneration, and direct emission will affect the surrounding environment. At present, only a powder spraying device is added to the inlet of the bag filter, so that the asphalt smoke and mineral powder are fully integrated, and the impurities in the flue gas are removed by the bag filter and then discharged. This filtering method cannot effectively filter the harmful gases generated during asphalt regeneration, but can only filter large particles of dust. It is difficult to effectively filter some harmful gases in the gas. Usually, multiple filtering methods are used for filtering. Bag filter devices are commonly used, but some stubborn dust is easily accumulated on the surface of the bag and it is not convenient to clean. Under long-term use, it is easy to affect the working efficiency of the bag and even damage the bag. In view of this situation, an asphalt regeneration multiple filtering device is proposed.
