Description

Technical Field

[0001] The utility model relates to the technical field related to tail gas treatment, and in particular to a tail gas treatment device for asphalt thermal regeneration equipment. Background Art

[0002] Asphalt thermal regeneration is a method of recycling materials by heating old asphalt. It is usually necessary to heat the asphalt surface in the old road surface to a temperature that can separate the old asphalt from the new asphalt, and then crush the old asphalt and mix it with the new asphalt. During the asphalt thermal regeneration process, a certain amount of exhaust gas will be generated due to the heating of the asphalt. In order to avoid exhaust gas pollution of the environment, the exhaust gas will be purified. There is currently an asphalt thermal regeneration equipment exhaust gas treatment device (application number: 201921569959.1) that is discharged into the atmosphere through the induced draft system. This type of asphalt thermal regeneration equipment exhaust gas treatment device first filters large particles of dust, then electrolyzes odorous gases, and finally filters fine dust. The smoke containing oil smoke will not enter the bag dust collector, which protects the bag dust collector, and the smoke is automatically cleared. The equipment has a long service life and can operate continuously for a long time.

[0003] As mentioned above, when treating the exhaust gas, it is necessary to use multiple sets of equipment to perform multi-stage dust removal to complete the purification of the exhaust gas. While there are many processing steps, the processing time is long and the processing efficiency is relatively low. Utility Model Content
