Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of circulating water cooling devices, specifically relating to a cooling tower. Background Technology
[0002] In existing cooling towers, after cold air is drawn into the bottom of the tower, it generally flows directly upward along the inner wall of the tower. The cold air is unevenly distributed at the bottom of the tower and has a short residence time, resulting in low heat exchange efficiency. This leads to a decrease in the cooling efficiency of the circulating water, thus affecting the use of the circulating water. Summary of the Invention
[0003] The purpose of this invention is to provide a cooling tower that is highly efficient at reducing the temperature of circulating water, addressing the shortcomings of existing technologies.
[0004] The technical solution adopted in this utility model is as follows.
[0005] A cooling tower includes a cooling water pool, several vertically arranged support columns, and a tower body. The tower body is connected to the cooling water pool via the support columns and is in the shape of a circular cylinder. An induced draft fan is installed at the top of the tower body. A vertical pipe is installed vertically along the center line of the tower body. Several grid-shaped dividing plates with their top surfaces parallel to the ground are installed horizontally inside the tower body. Several ring plates are arranged radially along the vertical pipe on each grid-shaped dividing plate, and the cross-section of each ring plate passing through the center line of the tower body is a wavy line. The vertical pipe passes through the center of each grid-shaped dividing plate, and its top end is connected to several spray pipes perpendicular to the center line of the tower body. The spray pipes are located above the uppermost ring plate and are arranged in a ring array along the vertical pipe. The bottom end of the vertical pipe is located below the lowermost grid-shaped dividing plate, and a water inlet is provided below the lowermost grid-shaped dividing plate of the vertical pipe. The water inlet is connected to a water pump installed outside the cooling water pool via a water inlet pipe.
[0006] The beneficial effects of this invention are as follows: The water pump draws circulating water from the inlet into the riser, then into the spray pipe, and finally sprays it out. The spray pipe is located above the uppermost ring plate and arranged in a ring array along the riser, ensuring thorough dispersion of the circulating water. The circulating water falls through the gaps between the ring plates and eventually into the cooling water tank. An induced draft fan is installed at the top of the tower, and cool air moves from bottom to top through the gaps between the ring plates, ultimately being discharged from the fan. Because the cross-section of the ring plate along the centerline of the tower is wavy, the circulating water does not fall directly into the cooling water tank; it spends a longer time passing through the gaps between the ring plates, resulting in a better cooling effect.
[0007] As a preferred technical solution, the bottom end of the riser is connected to the center of the bottom surface of the cooling water tank.
[0008] As a preferred technical solution, the tower body is made of metal. Using a metal tower body provides excellent heat dissipation.
[0009] As a preferred technical solution, the outer radial surface of the tower body is vertically provided with several metal heat sinks, which are arranged in a ring along the center line of the tower body. The presence of metal heat sinks allows for rapid dissipation of heat from the ring plates.
[0010] As a preferred technical solution, each spray pipe is equipped with several nozzles. The nozzles spray the circulating liquid, resulting in good heat dissipation.
[0011] As a preferred technical solution, a water pump is installed outside the cooling water tank, and the water pump is connected to the cooling water tank through a water pumping pipe.
[0012] As a preferred technical solution, several reinforcing ribs with their top surfaces parallel to the ground are coaxially arranged at the bottom of the tower body, and these reinforcing ribs are connected to each supporting column. In this way, the overall rigidity of the tower body is good.
[0013] As a preferred technical solution, a filter screen is installed on one of the reinforcing ribs, and the filter screen is higher than the top surface of the cooling water tank. The filter screen can filter impurities from the circulating water. Attached Figure Description

Detailed Implementation
[0025] The present invention will now be further described in conjunction with the accompanying drawings and embodiments.
[0026] Example 1. As... Figure 1-8 As shown, a cooling tower includes a cooling water tank 1, several vertically arranged support columns 2, and a tower body 3. The tower body 3 is connected to the cooling water tank 1 through the support columns 2. The tower body 3 is in the shape of a circular cylinder, and an induced draft fan 4 is provided at the top of the tower body 3. A riser 5 is vertically arranged on the center line of the tower body 3. Several grid dividing plates 6 with their top surfaces parallel to the ground are arranged horizontally inside the tower body 3. Several ring plates 7 are arranged radially along the riser 5 on each grid dividing plate 6. The cross section of each ring plate 7 passing through the center line of the tower body 3 is a wavy line. The riser 5 passes through the center of each grid dividing plate 6, and its top end is connected to several spray pipes 8 perpendicular to the center line of the tower body 3. The spray pipes 8 are located above the uppermost ring plate 7 and are arranged in a ring array along the riser 5. The bottom end of the riser 5 is located below the lowermost grid dividing plate 6. A water inlet 9 is provided below the lowermost grid dividing plate 6 of the riser 5. The water inlet 9 is connected to a water pump 11 located outside the cooling water tank 1 through a water inlet pipe 10. Specifically, in this embodiment, there are 6 support columns 2, arranged in a ring along the riser 5. The riser 5 is a steel pipe. The grid dividing plate 6 is a steel plate. The grid of the grid dividing plate 6 is used for water passage.
[0027] Tower body 3 is made of metal. Specifically, tower body 3 is made of bent and welded steel plates, which provides good heat dissipation.
[0028] The outer radial surface of the tower body 3 is provided with several metal heat sinks 12, which are arranged in a ring along the center line of the tower body 3.
[0029] Each spray pipe 8 is equipped with several nozzles 13. The nozzles 13 spray the circulating liquid, resulting in good heat dissipation.
[0030] A water pump 14 is installed outside the cooling water tank 1, and the water pump 14 is connected to the cooling water tank 1 through a water pumping pipe 15.
[0031] Three reinforcing ribs 16 with their top surfaces parallel to the ground are coaxially arranged at the bottom of the tower body 3, and the reinforcing ribs 16 are connected to each supporting column 2. In this way, the overall rigidity of the tower body is good.
[0032] The water pump 11 draws circulating water from the inlet 9 into the riser 5, then from the riser 5 into the spray pipe 8, and finally sprays it out from the spray pipe 8. The circulating water falls through the gaps between the ring plates 7 and finally into the cooling water tank 1. An induced draft fan 4 is installed at the top of the tower body 3. Cool air moves from bottom to top through the gaps between the ring plates 7 and is finally discharged from the induced draft fan 4. Because the cross-section of the ring plates 7 passing through the centerline of the tower body 3 is wavy, the circulating water does not fall directly into the cooling water tank 1; it takes a relatively long time to pass through the gaps between the ring plates 7, resulting in a better cooling effect. Under the action of the induced draft fan 4, air flows from bottom to top along the gaps between the ring plates 7; water flows from top to bottom along the gaps between the ring plates 7. Metal heat sinks 12 are provided to quickly dissipate the heat from the ring plates 7.
[0033] Example 2. (As shown) Figure 9 As shown, the difference between this embodiment and Embodiment 1 is that the bottom end of the riser 5 is connected to the center of the bottom surface of the cooling water tank 1. This results in better rigidity of the tower body.
[0034] Example 3. (As shown) Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that a filter screen 17 is installed on one of the reinforcing rib rings 16, and the filter screen 17 is higher than the top surface of the cooling water tank 1. The filter screen is provided to filter impurities from the circulating water.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
