Description

Technical Field

[0001] The invention belongs to the technical field of spray cooling tower structure design, and in particular relates to a gasified grey water swirl spray cooling tower. Background Art

[0002] In industrial production, especially in the gasification process, a large amount of high-temperature gasification ash water will be generated. This ash water is not only high in temperature, but also contains a variety of solid particles and impurities. If it is discharged directly, it will not only waste heat energy, but also pollute the environment. Therefore, it is particularly important to effectively cool and purify it. When treating this type of ash water, traditional gasification ash water cooling towers generally use a single spraying technology, that is, spraying water into the tower through a fixed nozzle, using the contact between water and air for heat exchange to achieve the purpose of cooling. However, this traditional spraying method has exposed many shortcomings in practical applications.

[0003] First, the traditional spraying method often has the problem of uneven water flow distribution. Since the nozzle is fixed, the direction and intensity of the water flow are difficult to adjust, resulting in excessive water flow in some areas and insufficient water flow in other areas. This uneven water flow distribution seriously affects the efficiency of heat exchange, making the cooling effect of gray water unsatisfactory. Secondly, under the traditional spraying method, the contact area between water and air is limited, which limits the rate of heat exchange. Fixed nozzles cannot form fine water droplets, making the contact area between water droplets and air relatively small, thereby reducing the efficiency of heat exchange. Summary of the invention

[0027] Specifically in this embodiment, the water tank 8 is made of stainless steel material, which has good corrosion resistance and structural strength, ensuring the long-term stable operation of the cooling tower. The four-way pipe body 705 and the atomizing nozzle 706 in the swirl spray mechanism 7 are made of corrosion-resistant alloy materials to ensure a long-term stable swirl spray effect. The swirl disk 708 is made of lightweight and high-strength aluminum alloy material to reduce the moment of inertia and improve the rotation efficiency.

[0028] See also Figures 3 to 5As shown, the upper surface of the water tank 8 is fixedly connected with a waterproof shell 12, the inner wall of the water tank 8 is installed with a water pump 10, the output end of the water pump 10 is fixedly connected with a water pipe 11, and the top of the water pipe 11 is rotatably connected with the connecting round rod 707. The water pipe 11 is fixedly connected with the inside of the water tank 8, and the inside of the waterproof shell 12 is rotatably connected with the connecting round rod 707. The outer surface of the water tank 8 is fixedly connected with a water inlet pipe 9, and the water inlet pipe 9 is fixedly connected with the inside of the tower body 1. The bottom surface of the water tank 8 is fixedly connected with a water collecting pan 5, and the water collecting pan 5 is fixedly connected with the inner bottom wall of the tower body 1. The outer surface of the water collecting pan 5 is fixedly connected with a water outlet pipe 6, and the water outlet pipe 6 is fixedly connected with the inside of the tower body 1. The water inlet pipe 9 is made of corrosion-resistant PVC material to ensure long-term stable water flow input. The water tank 8 is made of stainless steel material, which has good corrosion resistance and structural strength, ensuring the long-term stable operation of the cooling tower. The water collecting pan 5 is made of high-strength, corrosion-resistant polypropylene material, which has good structural stability and durability.

[0029] Specifically in this embodiment, by setting the water pump 10 and the water pipe 11, the water inside the water tank 8 can be continuously and stably pumped into the inside of the four-way pipe body 705, and sprayed out through the atomizing nozzle 706, thereby ensuring the continuity and stability of the spraying, further improving the cooling efficiency of the cooling tower, and at the same time, the setting of the water collecting tray 5 and the water outlet pipe 6 enables the cooled water to be discharged in time, thereby ensuring the smooth operation of the cooling tower. The water outlet pipe 6 is made of PVC material, which has excellent corrosion resistance and smooth water flow.

[0030] The working process of the present invention is as follows: first, a sufficient amount of water is injected into the water tank 8 through the water inlet pipe 9, and then the water pump 10 is started, and the water pump 10 pumps the water inside the water tank 8 into the inside of the four-way pipe body 705 through the water pipe 11, and then the water enters the atomizing nozzle 706 and is sprayed out through the atomizing nozzle 706. At the same time, the servo motor 701 is started, and the servo motor 701 drives the rotating shaft 702 to rotate, and the rotating shaft 702 drives the first gear 703 to rotate. Since the first gear 703 is meshed with the second gear 704, the first gear 703 will drive the second gear 704 to rotate, and the second gear 704 drives the four-way pipe body 705 to rotate. The tube body 705 and the connecting round rod 707 rotate inside the waterproof shell 12, thereby driving the swirl disk 708 to rotate. During the rotation process, the swirl disk 708 guides the water sprayed from the atomizing nozzle 706 through the swirl groove 709, so that the water forms a swirl inside the tower body 1 and fully contacts with the filler 4. At the same time, the axial flow fan 3 draws the external air into the tower body 1 through the air inlet window 2 and passes through the filler 4. At this time, the air and water are fully in contact on the surface of the filler 4 and heat exchange is performed, thereby cooling the water. The cooled water falls into the water collecting tray 5 under the action of gravity and is finally discharged through the outlet pipe 6. Through the above process, the gasification ash water swirl spray cooling tower of the present invention can effectively increase the contact area between water and air, thereby improving the efficiency of heat exchange. At the same time, the swirl design also makes the water flow distribution more uniform, thereby further improving the cooling effect.
