[0002] At present, the commonly used asphalt tank condensation asphalt fume treatment equipment includes a condenser tube, which is a hollow shell with an opening at the top. The condenser tube is provided with a smoke inlet pipe for allowing the asphalt fume to enter. The smoke inlet pipe is connected to the condenser tube. The condenser tube is filled with a cooling medium and is provided with a circulation component for circulating the cooling medium. When the asphalt fume is condensed, the asphalt fume is passed from the smoke inlet pipe into the condenser tube and then discharged from the top of the condenser tube. When the temperature of the cooling medium is greater than the set temperature, the circulation component is started to operate, and the circulation component circulates the coolant to cool it down;

[0003] However, the condensing flue gas treatment equipment in the prior art still has some shortcomings. For example, due to the heat exchange between the outer wall of the condenser tube and the outside air, the temperature of the asphalt flue gas and the cooling medium near the inner wall of the condenser tube is reduced, resulting in different temperatures of the asphalt flue gas and the cooling medium in the condenser tube. Therefore, the prior art needs to be improved. Utility Model Content
