Description

Technical Field

[0001] This invention relates to the field of cooling tower technology, and in particular to a high-efficiency water collection device and arrangement method for cooling towers. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. Cooling is achieved through the evaporation of water, and the cooling water can be continuously recycled, thus reducing waste costs from an economic perspective. The cooling method involves spraying hot water onto the surface of a heat dissipation material, allowing it to come into contact with the moving air. At this time, a sensible heat exchange occurs between the hot water and the cold air, and some of the hot water evaporates, releasing its latent heat of vaporization into the air. Finally, the cooled water falls into a water tank and is pumped to a heat exchanger to absorb heat again.

[0003] In traditional cooling towers, the water tank is typically located directly below the tower. During operation, water flows directly into the tank after passing through the packing material. This method has several drawbacks: if the distance between the tank and the tower is too short, airflow is obstructed, reducing cooling efficiency; if the distance is too long, water splashes out, wasting water. To improve cooling efficiency and reduce water waste, we propose a water collection device positioned between the packing material and the tank to address these issues. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency water collection device and arrangement method for cooling towers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency water collection device for cooling towers includes a water collection section composed of multiple water collection mechanisms arranged at equal intervals. Each water collection mechanism includes at least one water collection trough, which is inclined at an angle of less than 5°. The water collection trough includes a V-shaped cross-section with an opening angle of 55°-65°. At least one horizontal plate of equal length to the trough is provided at the upper edge of the trough, and a vertical plate is fixedly installed at the edge of the horizontal plate.

[0007] Preferably, the overlap distance between adjacent water collection mechanisms is greater than the width of the horizontal plate.

[0008] Preferably, the spacing between adjacent tanks is 1.5-2 times the height of the tank.

[0009] Preferably, the water collection mechanism includes a first water collection mechanism, a second water collection mechanism, and a third water collection mechanism.

[0010] The first water collection mechanism includes a first water collection trough, a second water collection trough, and a third water collection trough arranged from top to bottom. A first connecting plate is connected between the first water collection trough, the second water collection trough, and the third water collection trough. The first connecting plate is located on the extension surface of the side wall of the first water collection trough, the second water collection trough, and the third water collection trough.

[0011] The second water collection mechanism includes a first water collection trough, and a first connecting plate is provided at the lower end of the first water collection trough along the extension surface of its side wall;

[0012] The third water collection mechanism includes a first water collection trough and two corresponding second water collection troughs. The second water collection troughs are connected to the side wall of the first water collection trough through a second connecting plate.

[0013] Preferably, a method for arranging a high-efficiency water collection device for a cooling tower includes the following steps:

[0014] Step 1: Determine the number and type of water collection mechanisms based on the dimensions of the water tower;

[0015] Step 2: Fix the third water collection mechanism in the middle of the water tower, fix the first water collection mechanism on both sides of the third water collection mechanism, and make the first water collection trough in the third water collection mechanism flush with the second water collection trough in the first water collection mechanism. Finally, install the second water collection mechanism in the area at the edge of the water collection section.

[0016] Step 3: Install a water tank on the outer wall of the water tower that is compatible with the water collection section.

[0017] Preferably, the opening angle of the tank, the overlap distance between adjacent water collection mechanisms, and the layer spacing between adjacent tanks are determined based on the flow rate and temperature of the water in the water tower.

[0018] The beneficial effects of this invention are:

[0019] 1. In this device, the water collection section is located below the packing. When the water tower is running, air flows upward from the bottom of the water collection section, and circulating water is sprayed downward. The air exchanges heat with the circulating water above through the water collection section. All the circulating water is collected by the water collection section, and there is no circulating water below the water collection section. The heat exchange effect of the water tower is good, and water droplets are not easy to splash out, reducing the waste of water resources.

[0020] 2. The tank is equipped with horizontal plates to prevent droplets from flowing along the lower wall and vertical plates to prevent splashing, which further reduces the waste of water resources.

[0021] 3. Based on the flow rate and temperature of the water in the water tower, determine the opening angle of the tank, the overlap distance between adjacent water collection mechanisms, and the layer spacing between adjacent tanks. When the water temperature is high, increasing the opening angle and the layer spacing between adjacent tanks can improve the heat exchange effect. When the water flow rate is large, it is necessary to appropriately increase the overlap distance between adjacent water collection mechanisms to reduce water loss. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Reference Figure 1-9 A high-efficiency water collection device for cooling towers includes a water collection section 1, which is composed of multiple water collection mechanisms arranged at equal intervals. Each water collection mechanism includes at least one water collection trough, which is inclined at an angle of less than 5°. The water collection trough includes a V-shaped trough body 101 with an opening angle of 55°-65°. At least one horizontal plate 102 of the same length as the trough body 101 is provided at the upper edge of the trough body 101, and a vertical plate 103 is fixedly installed at the edge of the horizontal plate 102.

[0037] The overlap distance 105 between adjacent water collection mechanisms is greater than the width of the horizontal plate 102.

[0038] The layer spacing 104 between adjacent tanks 101 is equal to 1.5-2 times the height of the tank 101.

[0039] The water collection mechanism includes a first water collection mechanism 2, a second water collection mechanism 3, and a third water collection mechanism 4.

[0040] The first water collection mechanism 2 includes a first water collection trough 11, a second water collection trough 12 and a third water collection trough 13 arranged from top to bottom. A first connecting plate 14 is connected between the first water collection trough 11, the second water collection trough 12 and the third water collection trough 13. The first connecting plate 14 is located on the extension surface of the side wall of the first water collection trough 11, the second water collection trough 12 and the third water collection trough 13.

[0041] The second water collection mechanism 3 includes a first water collection trough 11, and a first connecting plate 14 is provided at the lower end of the first water collection trough 11 along the extension surface of its side wall.

[0042] The third water collection mechanism 4 includes a first water collection trough 11 and two corresponding second water collection troughs 12. The second water collection troughs 12 are connected to the side wall of the first water collection trough 11 through a second connecting plate 15.

[0043] A method for arranging a high-efficiency water collection device for a cooling tower includes the following steps:

[0044] Step 1: Determine the number and type of water collection mechanisms based on the dimensions of water tower 6;

[0045] Step 2: Fix the third water collection mechanism 4 in the middle of the water tower 6, fix the first water collection mechanism 2 on both sides of the third water collection mechanism 4, and make the first water collection trough 11 in the third water collection mechanism 4 flush with the second water collection trough 12 in the first water collection mechanism 2. Finally, install the second water collection mechanism 3 in the area at the edge of the water collection part 1.

[0046] Step 3: Install a water tank 7 on the outer wall of the water tower 6 that is compatible with the water collection section 1.

[0047] Based on the flow rate and temperature of the water in the water tower 6, determine the opening angle of the tank 101, the overlap distance 105 between adjacent water collection mechanisms, and the layer spacing 104 between adjacent tanks 101.

[0048] In this device, the water collection section 1 is located below the packing. When the water tower 6 is running, air flows upward from the bottom of the water collection section 1, and circulating water is sprayed downward. The air exchanges heat with the circulating water above through the water collection section 1. All the circulating water is collected by the water collection section 1, and there is no circulating water below the water collection section 1. The heat exchange effect of the water tower 6 is good, and water droplets are not easy to splash out, thus reducing the waste of water resources.

[0049] The tank is equipped with a horizontal plate 102 to prevent droplets from flowing along the lower wall and a vertical plate 103 to prevent splashing, which further reduces the waste of water resources.

[0050] Based on the flow rate and temperature of the water in water tower 6, the opening angle of tank 101, the overlap distance 105 between adjacent water collection mechanisms, and the layer spacing 104 between adjacent tanks are determined. When the water temperature is high, increasing the opening angle and the layer spacing 104 between adjacent tanks 101 can improve the heat exchange effect. When the water flow rate is large, it is necessary to appropriately increase the spacing between adjacent water collection mechanisms.

[0051] The overlap distance between them should be reduced to minimize water loss.

[0052] In Comparative Example 1, reference Figure 10 In the water collection section 1, no third water collection mechanism 4 is provided. The first water collection mechanism 2 at its outermost edge is directly connected to the inner wall of the water tower 6. There is a blind zone between the first water collection mechanism 2 at its outermost edge and the inner wall of the water tower 6 when the airflow flows, which affects the heat exchange to a certain extent.

[0053] In Comparative Example 2, reference Figure 11In the water collection section 1, there is no third water collection mechanism 4, and the fourth water collection mechanism 5 in the middle is spliced ​​together from two first water collection mechanisms 2. As a result, there is a blind zone below the fourth water collection mechanism 5 when the airflow is flowing, which affects the heat exchange to a certain extent.

[0054] In Comparative Example 3, reference Figure 12 In the water collection section 1, no third water collection mechanism 4 is provided, and the middle water collection mechanism is spliced ​​together by two first water collection mechanisms 2 facing opposite directions. Similar to Comparative Example 2, there is a blind zone under the middle water collection mechanism when the airflow flows, which affects the heat exchange to a certain extent.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
