Technical Field
[0001] This utility model relates to the field of cooling spray technology, and in particular to a cooling water spray structure for a heating furnace. Background Technology
[0002] In many industrial sectors, such as steel, chemical, and building materials, heating furnaces are commonly used equipment. For example, in the production of hot-rolled steel profiles, steel billets are heated to over 1300 degrees Celsius in the heating furnace. The heating furnace generates a large amount of heat during operation. To ensure its normal operation and service life, key components of the heating furnace, such as the furnace door and the walking beam inside the furnace, need to be cooled and protected. Cooling water pipes are usually installed in these components to circulate cooling water. The high-temperature water after cooling needs to be cooled down through effective cooling methods so that it can be recycled. Cooling spray structure is one of the key technologies to achieve this goal.
[0003] Taking a large heating furnace in a steel plant as an example, its cooling system consumes thousands of cubic meters of cooling water daily. During the spray cooling process, a large amount of cooling water vaporizes into water vapor and is discharged through the air outlet. This discharged water vapor cannot be recovered and reused, forcing enterprises to continuously replenish fresh water resources, which not only increases their dependence on local water resources but also increases water acquisition costs. Utility Model Content
[0004] The purpose of this invention is to provide a cooling water spray structure for a heating furnace. Through a collection trough on the upper surface of the cooling tower, water droplets formed by condensation of water vapor can be effectively collected. The collected water then flows through a guide channel into subsequent cooling processes such as a serpentine square tube, achieving water resource recycling and reducing waste. This function is particularly important for areas with relatively scarce water resources or scenarios with high requirements for water cost control. It not only reduces water expenses but also reduces related costs for treating and replenishing water, such as the cost of chemicals for water purification, thereby lowering the overall operating cost of the cooling system.

The baffle 4 is fixedly connected to the upper surface of the support columns 5, serving as... The baffle 4 serves to prevent external debris from falling into the cooling tower and provides an installation base for the water guide plate 6. The water guide plate 6 is fixedly connected to the lower surface of the baffle 4. The water guide plate 6 accurately guides the falling water to the collection tank 17, improving the water collection efficiency. The side wall of the guide tank 18 is provided with a serpentine square tube 19, and both ends of the serpentine square tube 19 are fixedly connected to the cooling tower 1.

The interior of the guide tank 18 is connected to the interior of the serpentine square tube 19, and the guide tank 18 delivers water to the serpentine square tube 19, providing the necessary water for the cooling process within the serpentine square tube 19. The serpentine square tube 19 extends into the interior of the cooling tower 1, facilitating water cooling within the cooling tower environment. The interior of the serpentine square tube 19 is connected to the side wall of the sealing block 20, ensuring that the sealing block 20 can effectively control the flow direction and sealing of water within the serpentine square tube 19. The position of the water guide plate 6 corresponds to the position of the collection tank 17, allowing the water guided by the water guide plate 6 to accurately fall into the collection tank 17. The cross-section of the serpentine square tube 19 is G-shaped, and this special shape further increases the contact area between water and air, improving cooling efficiency. An air outlet 2 is fixed on the upper surface of the cooling tower 1, and the air outlet 2 is located below the baffle 4. The air outlet 2 discharges hot air from the cooling tower, promoting air circulation. An exhaust fan 3 is installed inside the air outlet 2 to accelerate airflow, enhance heat exchange, and improve cooling capacity. A baffle plate 7 is fixedly connected to the inner wall of the cooling tower 1, and the baffle plate 7 is located between the two ends of the serpentine square tube 19. The baffle plate 7 prevents water from splashing out of the serpentine square tube 19 and ensures that the water flows within a specified path. Second water inlet pipes 22 are fixedly connected to both the left and right sides of the outer surface of the cooling tower 1. The second water inlet pipes 22 replenish the cooling system with new water and maintain the normal operation of the system. Several first water inlet pipes 8 are fixedly connected to the lower surface of the second water inlet pipes 22, and the first water inlet pipes 8 are located inside the cooling tower 1. The first water inlet pipes 8 disperse and deliver the water from the second water inlet pipes 22 to each nozzle 9. Several nozzles 9 are fixedly connected to the outer surface of each first water inlet pipe 8.

The packing material 11 is fixed to the outer surface of the fixed column 10, which is connected to the inner wall of the cooling tower 1. The water on the packing material 11 increases the contact area and residence time with the air, thus initially lowering the water temperature. Water falling from the outside is guided by the water guide plate 6 on the lower surface of the baffle 4 to the collection tank 17. The collection tank 17 is on the upper surface of the cooling tower 1, and the water in the collection tank 17 flows into the guide channel 18 connected to it.

On the surface, the guide channel 18 directs water to the serpentine square tube 19, whose two ends are fixedly connected to the cooling tower 1. Its cross-section is G-shaped, increasing the water flow path and contact area with air, further enhancing the cooling effect. The sealing block 20 is fixed to the side wall of the serpentine square tube 19 by positioning bolts 21 to prevent water leakage. A baffle plate 7 is located between the two ends of the serpentine square tube 19, fixed to the inner wall of the cooling tower 1, preventing water from splashing out of the serpentine square tube 19 and ensuring that the water flows within the designated path. The cooled water flows into the sinking block 15. 15 is connected to the interior of cooling tower 1 and located on the lower surface of cooling tower 1. Support leg 12 supports the entire cooling tower 1 to ensure its stability. The operating parameters of the cooling system, such as the wind speed of exhaust fan 3, can be controlled by controller 13. The cooled water is discharged from cooling tower 1 through water outlet pipe 14, which is fixed to the front surface of cooling tower 1. Filter module 16 is located on the left and right sides of the outer surface of cooling tower 1 and is connected to the interior of cooling tower 1. It filters the water in the system, removes impurities, ensures water quality, and prevents impurities from damaging the system.
