[0002] Asphalt is a complex, dark brown mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, appearing liquid with a black surface, and is soluble in carbon disulfide. Asphalt is a widely used organic cementitious material with waterproof, moisture-proof, and corrosion-resistant properties. It is an important raw material in the carbon industry. However, asphalt and its fumes are irritating to the skin and mucous membranes, and have phototoxic and carcinogenic effects. Therefore, how to more efficiently recover and reuse asphalt fumes during production while meeting environmental standards is a continuous research and development direction for the industry.

[0027] In this embodiment, a third connecting pipe 11 is fixedly connected to the outer surface of the second recycling box 6, and a spray tower 12 is fixedly connected to one end of the third connecting pipe 11.

[0028] In practical use, the flue gas that has undergone secondary recovery enters the spray tower 12 through the third connecting pipe 11 for water curtain adsorption and cooling, thereby achieving the purification effect.

[0039] Working Principle: In operation, asphalt fumes are first discharged through the inlet pipe 2 and stored inside the fumes storage tank 1. The booster pump 20 increases the pressure inside the fumes storage tank 1, driving the stored asphalt fumes to be squeezed into the subsequent recycling process for recycling. After some driving force, the fumes are discharged through the first connecting pipe 3 into the first recycling box 4. The first recycling box 4 contains water, and the fumes pass through the water for the first layer of recycling and purification, cooling and cooling down to form a layer of oily wastewater, which facilitates the first layer of recycling. The remaining fumes enter the second recycling box 6 through the second connecting pipe 5. With the help of the cooler, the cooling grid 7 and the conical cooling column 8 cool and cool the fumes. The conical cooling column 8 increases the contact area with the fumes, improving the efficiency of cooling liquefaction. The liquefied asphalt fumes are collected and guided by the conical cooling column 8 and the pocket-shaped collection pipe 9 into the recycling box 10 for recycling, realizing the secondary recycling of asphalt fumes. This effectively reduces asphalt fume emissions and enhances the environmental friendliness of the device. The flue gas after secondary recovery enters the spray tower 12 through the third connecting pipe 11 for water curtain adsorption and cooling, achieving a purification effect. The purified flue gas enters the purification box 14 through the fourth connecting pipe 13 for final adsorption. The purification box 14 is equipped with activated carbon plates for adsorption and purification. Finally, the flue gas is discharged through the discharge pipe 15. The oily wastewater inside the first recovery box 4 is recovered and cleaned through the operating door 16. The process of recovering the cooled and liquefied asphalt fume inside the second recovery box 6 can be observed through the observation window 17, improving visibility. Opening the protective cover 19 allows the recovery pipe 18 to discharge the liquefied asphalt fume recovered by the recovery box 10. The one-way valve 21 controls the flow direction of the flue gas inside the first connecting pipe 3, the second connecting pipe 5, the third connecting pipe 11, and the fourth connecting pipe 13 to prevent flue gas backflow.
