[0002] When producing asphalt, a large amount of high-temperature flue gas is generated by dust, and the flue gas contains a large amount of particulate pollutants, which need to be filtered. Before filtration, the flue gas needs to be cooled down first.

[0003] Chinese Patent CN220990035U discloses an asphalt fume absorption device in the production process of coated asphalt, including: a body, including a cyclone dust collector, one end of the cyclone dust collector is fixedly connected with an input pipe, the other end of the cyclone dust collector is fixedly connected with a communicating pipe, the surface of the communicating pipe is fixedly connected with an absorption box, the upper surface of the absorption box is fixedly connected with an exhaust port, and the inner surface of the input pipe is fixedly connected with a spraying device; a condensation mechanism, including a condensation pipe. By installing a condensation pipe inside the input pipe, when the asphalt fume passes through the condensation pipe device, under the action of the condensation pipe, the effect of initially increasing the dust particles of the asphalt fume is achieved, so that the asphalt fume is more fully purified after entering the cyclone dust collector, and through grooves are opened on the surface of the input pipe for the purpose of taking out the entire condensation mechanism when the condensation pipe needs to be replaced after long-term use.

[0004] When the above patent is in use, the condensation pipe is used to cool the pipeline through the pipeline. However, the shape of the condensation pipe is winding, and the dust in the flue gas is easy to accumulate inside the condensation pipe to cause blockage, and the above patent does not have the function of cleaning the condensation pipe and is easy to be blocked. Therefore, in view of the above situation, there is an urgent need to develop an asphalt fume absorption device in the production process of coated asphalt that is convenient for cleaning the condensation pipe and preventing blockage to overcome the deficiencies in current practical applications and meet current needs.
