Description

Technical Field

[0001] This utility model relates to the field of asphalt fume recovery technology, and in particular to an asphalt storage tank capable of recovering asphalt fume. Background Technology

[0002] Asphalt is widely used as a key raw material in many fields such as road construction and waterproofing projects. The authorization announcement number "CN221342231U" discloses an asphalt storage tank for convenient recovery of asphalt fumes. This asphalt storage tank for convenient recovery of asphalt fumes uses an exhaust fan to transport the asphalt fumes generated by hot asphalt inside the asphalt tank to the recovery tank. A water-cooled plate is installed to facilitate the condensation of the asphalt fumes inside the recovery tank. At the same time, the drive motor drives the blades to rotate, which agitates the asphalt fumes inside the recovery tank, allowing the asphalt fumes to come into uniform contact with the water-cooled plate, greatly improving the condensation efficiency and resulting in high recovery efficiency.

[0003] During the use of the above technical solution, the condensation effect of the water-cooled plate largely depends on the temperature of the cooling water. The cooling water absorbs heat from the asphalt fumes during circulation. If there is no special heat dissipation structure to dissipate the heat to the environment, the temperature of the cooling water will continue to rise. The rise in water temperature will reduce the temperature difference between the water and the asphalt fumes, thereby weakening the heat exchange effect and causing a decrease in condensation efficiency. Therefore, we propose an asphalt storage tank that can recover asphalt fumes. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an asphalt storage tank that can recover asphalt fumes. This solves the problem that the condensation effect of the water-cooled plate largely depends on the temperature of the cooling water. During the circulation process, the cooling water absorbs heat from the asphalt fumes. If there is no special heat dissipation structure to dissipate the heat to the environment, the temperature of the cooling water will continue to rise. The rise in water temperature will reduce the temperature difference between the water and the asphalt fumes, thereby weakening the heat exchange effect and causing a decrease in condensation efficiency.

Exhaust fan 8: Fixedly installed on the top of the small spray tank 6, with the exhaust end connected to the inside of the small spray tank 6, used to extract the residual flue gas inside the small spray tank 6 to achieve deep treatment of flue gas; Connecting pipe 9: It is fixedly connected to the top of the flue gas condensation box 3, and the end away from the flue gas condensation box 3 is fixedly connected to the small spray tank 6. It is used to transport the residual flue gas after condensation treatment in the flue gas condensation box 3 to the small spray tank 6. Cooling box 10: As a cooling space for cooling water, it has multiple air outlets 11 on the top to discharge air carrying heat, and multiple air inlets 13 on the side away from the flue gas condenser box 3 to draw in cold air from the outside. Heat dissipation pipes 17 are fixedly installed inside, and exhaust fans 14 are installed inside the air inlets 13. Air outlet 11: Multiple outlets are located on the top of the cooling box 10 to exhaust the air inside the cooling box 10 that carries the heat from the heat dissipation pipe 17. Return pipe 12: One end is fixedly connected to the end of condenser pipe 15 away from water pump 4, and the other end extends to the outside of flue gas condenser box 3 and is fixedly connected to heat dissipation pipe 17. It is used to transport the cooling water that has completed heat exchange and temperature rise in condenser pipe 15 to heat dissipation pipe 17. Air inlets 13: Multiple inlets are located on the side of the cooling box 10 away from the flue gas condenser box 3. An exhaust fan 14 is installed inside the cooling box 10 to allow outside cold air to enter the cooling box 10. Exhaust fans 14: Multiple fans are arranged in a linear array inside the air inlet 13 of the cooling box 10 to draw in cold air from the outside and accelerate the air flow inside the cooling box 10 to assist the cooling water in cooling down. Condenser 15: It is fixedly installed inside the flue gas condenser box 3. One end is fixedly connected to the drain end of the water pump 4, and the other end is fixedly connected to the return pipe 12. Cooling water flows inside, which can fully exchange heat with the asphalt flue gas in the flue gas condenser box 3 to liquefy the flue gas. Multiple heat dissipation fins 16 are fixedly sleeved on the outside of the heat dissipation pipe 17 to increase the contact area between the heat dissipation pipe 17 and the cold air inside the cooling box 10, and accelerate the heat dissipation of the cooling water inside the heat dissipation pipe 17. Heat dissipation pipe 17: It is fixedly installed inside the cooling box 10, and multiple heat dissipation fins 16 are fixedly sleeved on the outside. One end is connected to the condenser pipe 15 through the return pipe 12, and the other end extends to the outside of the cooling box 10 and is connected to the inside of the water storage tank 7. It is used to contain the high temperature cooling water delivered from the return pipe 12. After cooling in the cooling box 10, it flows back to the water storage tank 7.

[0021] Example 1: like Figure 1-4 As shown, in hot and humid regions, the asphalt storage tank 1 continuously generates a large amount of asphalt fumes during operation. The fumes enter the fumes condenser 3 through the exhaust pipe 2 for condensation treatment. During this process, the coolant absorbs heat and its temperature rises. The coolant in the water tank 7 is pumped by the water pump 4 to the condenser pipe 15 in the fumes condenser 3, and then enters the heat dissipation pipe 17 of the cooling box 10 through the return pipe 12.

[0022] Multiple exhaust fans 14 arranged in a linear array on the cooling tank 10 are turned on simultaneously to form a powerful airflow. The air inlet 13 introduces relatively cool outside air, which flows quickly through the heat dissipation pipe 17 under the action of the exhaust fans 14, so that the high-temperature coolant can fully exchange heat with the air. The multiple exhaust fans 14 work together to greatly accelerate the air flow speed, which can more quickly remove the heat of the coolant, so that the coolant can be cooled down quickly and then flow back to the water storage tank 7, ensuring the efficient operation of the entire coolant circulation system and continuously providing low-temperature coolant for flue gas condensation.

[0023] Example 2: like Figure 4As shown, during the peak season for asphalt production, the main body of the asphalt storage tank 1 operates under high load for a long time, resulting in a significant increase in the amount of asphalt fumes produced. This increases the cooling capacity required for condensation of the fumes and the heat absorption of the coolant.

[0024] Multiple heat dissipation fins 16 are fixedly sleeved on the outside of the heat dissipation pipe 17 inside the cooling box 10. The heat dissipation fins 16 are made of metal with high thermal conductivity. When the high temperature coolant flows through the heat dissipation pipe 17, the heat is quickly conducted to the heat dissipation fins 16. The large area design of the heat dissipation fins 16 increases the contact area with the air, enhances the convective heat transfer effect between the air and the heat dissipation fins 16, and can transfer the heat of the coolant to the air more efficiently, improve the heat dissipation efficiency of the coolant, and meet the cooling requirements of flue gas condensation under high load conditions.

[0025] Furthermore, when using this device, when asphalt is injected into the tank through the feed pipe at the top of the asphalt storage tank body 1, the asphalt fumes generated by the asphalt being heated and volatilized will accumulate in the tank. At this time, the exhaust pipe 2 fixedly connected to the top of the asphalt storage tank body 1 serves as a fumes outlet channel, stably transporting the asphalt fumes in the tank to the inside of the fumes condensation box 3, thus completing the initial collection and transfer of fumes.

[0026] Then, the water pump 4 starts, and its pumping end draws out the cooling water stored in the water storage tank 7. The cooling water is then transported through the drain end of the water pump 4 to the condenser pipe 15 that extends into the flue gas condenser box 3. Since the condenser pipe 15 is fixedly installed inside the flue gas condenser box 3, the flowing cooling water can fully exchange heat with the asphalt flue gas inside the box. The asphalt flue gas liquefies upon cooling to form liquid asphalt, thus realizing the recovery of effective components in the flue gas. The cooling water that has completed heat exchange and increased in temperature is then transported through the return pipe 12 to the heat dissipation pipe 17 inside the cooling box 10.

[0027] After the heated cooling water enters the radiator pipe 17, multiple exhaust fans 14 on the cooling tank 10 are activated. The exhaust fans 14 draw in cold air from the outside through the air inlet 13. As the cold air flows inside the cooling tank 10, it comes into contact with multiple heat dissipation fins 16 fixedly fitted to the outside of the radiator pipe 17. The heat dissipation fins 16 increase the heat dissipation area and accelerate the dissipation of heat from the cooling water inside the radiator pipe 17. The air carrying heat is then discharged through multiple air outlets 11 at the top of the cooling tank 10, thus cooling the cooling water. The cooled water extends through the radiator pipe 17 to one end outside the cooling tank 10 and flows back into the water storage tank 7. The consumed cooling water can be replenished through the water inlet pipe fixedly connected to the top of the water storage tank 7, forming a stable cooling water circulation system.

[0028] The residual flue gas after condensation treatment in the flue gas condensation box 3 is transported to the small spray tank 6 through the connecting pipe 9 fixedly connected to the top of the flue gas condensation box 3. The exhaust fan 8 fixedly installed on the top of the small spray tank 6 is started, and its exhaust end extracts the residual flue gas from the small spray tank 6, realizing the deep treatment of the flue gas. The liquid asphalt waste liquid generated by condensation in the flue gas condensation box 3 is discharged through the drain pipe 5 fixedly connected to the side of the flue gas condensation box 3 near the small spray tank 6, which facilitates subsequent treatment.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
