Description

Technical Field

[0001] This utility model relates to the technical field of air cooler equipment, and in particular to a spray humidification type cooling nozzle for coal tar hydrogenation air cooler. Background Technology

[0002] In the coal tar hydrogenation production process, the air cooler cooling nozzle plays a crucial role. Its core function is to cool the high-temperature products after the hydrogenation reaction to a suitable temperature, ensuring that subsequent separation, purification and other processes can proceed smoothly.

[0003] However, existing cooling nozzles for coal tar hydrogenation air coolers have many shortcomings. The contact area between the cooling medium and the high-temperature hydrogenation products is limited, resulting in insufficient heat exchange and slow cooling speed. This makes it difficult to meet the rapid cooling requirements of large-scale continuous production. At the same time, there is a lack of effective energy-saving control measures. Existing cooling nozzles lack a complete water recovery and reuse mechanism, and a large amount of water is lost in the form of water mist during evaporation. This not only increases the cost of production water but also does not conform to the green production concept of energy conservation and emission reduction.

[0004] Therefore, a spray-humidified coal tar hydrogenation air cooler cooling nozzle was designed. Summary of the Invention

[0005] To overcome the shortcomings of insufficient cooling effect and high energy consumption of existing equipment, the technical problem to be solved is to provide a spray humidification type cooling nozzle for a coal tar hydrogenation air cooler.

[0006] The technical solution is as follows: A spray-humidified coal tar hydrogenation air cooler cooling nozzle includes a cooling tower, an axial flow fan, hot water pipes, cold water pipes, a cooling indoor unit, a first water pump, heat dissipation pipes, an evaporation tank, water curtains, spray pipes, a circulating water pipe, and a second water pump. An evaporation tank is installed at the top of the cooling tower, an axial flow fan is installed above the water separator, and multiple water curtains are installed at the bottom of the evaporation tank. A heat dissipation pipe is installed inside the cooling tower near the water curtains. One end of the heat dissipation pipe is connected to a hot water pipe, and the other end of the heat dissipation pipe is connected to the first water pump. The other end of the first water pump is connected to a cold water pipe, and the other ends of the hot water pipe and the cold water pipe are connected to the cooling indoor unit. A second water pump is installed inside the cooling tower, and the second water pump is connected to a circulating water pipe. A spray pipe is connected to the end of the circulating water pipe near the evaporation tank.

[0007] In one embodiment, a condenser pipe is also included, with the condenser pipe installed between the cooling tower and the indoor cooling unit.

[0008] In one embodiment, the heat dissipation pipe and the circulating water pipe adopt a spiral bending structure design.

[0009] In one embodiment, a dewatering device is also included, which is installed above the evaporation tank.

[0010] In one embodiment, the cooling tower also includes ventilation windows, with multiple ventilation windows located around its perimeter.

[0011] In one embodiment, the water curtain is formed by connecting multiple corrosion-resistant alloy links sequentially in a hinged manner. Beneficial effects

[0012] 1. This utility model atomizes water through the atomizing nozzle of the spray pipe, and combines the water curtain structure and axial flow fan to accelerate air flow, which greatly increases the contact area between water and air, improves the water evaporation rate, and thus significantly improves the cooling efficiency of coal tar hydrogenation products, meeting the cooling needs of large-scale production.

[0013] 2. This utility model uses a condenser tube to return the condensate generated by the cooling unit to the cooling tower, thus constructing a complete water resource circulation system. This avoids water waste caused by the discharge of condensate, reduces production water costs, and maintains a stable water level in the cooling tower, ensuring the continuous and stable operation of the cooling system.

Detailed Implementation

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0020] Example: A spray-humidified cooling nozzle for a coal tar hydrotreating air cooler, such as... Figure 1-4As shown, the system includes a cooling tower 1, an axial flow fan 2, a hot water pipe 3, a cold water pipe 4, a cooling indoor unit 5, a first water pump 7, a heat dissipation pipe 8, an evaporation tank 9, a water curtain 10, a spray pipe 11, a circulating water pipe 12, and a second water pump 13. The evaporation tank 9 is installed at the top of the cooling tower 1, and the axial flow fan 2 is installed above the water separator 14. Multiple water curtains 10 are installed at the bottom of the evaporation tank 9. The heat dissipation pipe 8 is installed inside the cooling tower 1 near the water curtain 10. One end of the heat dissipation pipe 8 is connected to the hot water pipe 3, and the other end of the heat dissipation pipe 8 is connected to the first water pump 7. The other end of the first water pump 7 is connected to the cold water pipe 4. The other ends of the hot water pipe 3 and the cold water pipe 4 are connected to the cooling indoor unit 5. The second water pump 13 is installed inside the cooling tower 1. The second water pump 13 is connected to the circulating water pipe 12, and the end of the circulating water pipe 12 near the evaporation tank 9 is connected to the spray pipe 11.

[0021] like Figure 1 As shown, a condenser pipe 6 is installed between the cooling tower 1 and the indoor unit 5 to allow the condensate generated by the indoor unit 5 to flow back to the cooling tower 1, thus constructing a complete water resource circulation system and avoiding the waste of water resources caused by the discharge of condensate.

[0022] like Figure 3-4 As shown, the heat dissipation pipe 8 and the circulating water pipe 12 adopt a spiral bending structure design, which greatly increases the flow path length of the fluid in the heat dissipation pipe 8 and the circulating water pipe 12, prolongs the heat exchange time between the water flow and the outside air, and between the heat dissipation pipe 8 and the water curtain 10, and enhances the heat exchange effect.

[0023] like Figure 1-2 As shown, a water separator 14 is installed above the evaporation tank 9 to effectively intercept the water mist generated during the evaporation process, prevent water from being lost with the airflow, and improve the water resource recycling rate.

[0024] like Figure 1-2 As shown, multiple air vents 101 are provided around the cooling tower 1 to introduce outside air, which works in conjunction with the airflow generated by the axial flow fan 2 to promote air circulation inside the cooling tower.

[0025] like Figure 3 As shown, the water curtain 10 is composed of multiple corrosion-resistant alloy links connected sequentially by hinges. The hinged links form a three-dimensional interlaced water flow channel, which increases the contact area between water and air, promotes uniform water flow distribution, and enhances the effects of water evaporation and heat exchange.

[0026] First, a certain amount of water is injected into the cooling tower 1 as a cooling medium. Then, the second water pump 13 is started, drawing water from the cooling tower 1 and delivering it through a spirally curved circulating water pipe 12 to the spray pipe 11. The atomizing nozzles on the spray pipe 11 atomize the water and spray it into the evaporation tank 9. The atomized water forms a water film within the evaporation tank 9, and the water flows slowly down along a water curtain 10 made of multiple layers of fiber material, falling into the cooling tower 1. During the water descent, the outside air flowing in through the vent 101 of the cooling tower 1 accelerates the evaporation of the water. Because the heat dissipation pipe 8 is installed close to the water curtain 10, the falling water can fully absorb the heat from the surface of the heat dissipation pipe 8 and evaporate, cooling the high-temperature medium inside the heat dissipation pipe 8. The water vapor that has absorbed heat is discharged from the cooling tower 1 through the axial flow fan 2. The cooled water that has absorbed heat returns to the cooling unit 5 through the first water pump 7. The cooling unit 5, through a series of operations of refrigeration components such as the compressor, condenser, and evaporator, cools the cooled water and blows out cold air to cool the coal tar hydrogenation products. The water that has absorbed heat flows back into the heat dissipation pipe 8 through the hot water pipe 3 to continue participating in the heat exchange cycle.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
