Description

Technical Field

[0001] The invention relates to the technical field of cooling towers, and in particular to a closed cooling tower. Background Art

[0002] A cooling tower is a device that can cool water. There are mainly cross-flow and counter-flow types. Hot water flows vertically from the top of the tower, and air flows horizontally through the water-sprinkling filler. The airflow and water flow are orthogonal to each other for cooling, which is the cross-flow type. Water flows vertically in the tower, and the direction of the airflow is opposite to that of the water flow, which is the counter-flow type.

[0003] Taking the countercurrent closed cooling tower as an example, the closed type is closed-cycle cooling, which is to place the coil in the tower, above the coil is the water outlet of the spray system, there is filler under the coil, and there is a water storage tank under the filler. The water storage tank is connected to the spray system to guide the water in the tank to the top of the coil, and the cooling effect is guaranteed by the heat exchange of circulating air, spray water and circulating water, forming a closed cycle.

[0004] The closed tower uses steel plate as the main structure, and a steel structure frame is installed inside. In real life, the square closed tower is common. The square cooling tower uses air intake on both sides, and the exhaust fan on the top allows the air to pass through the filler and coil and then be discharged outside the tower. In detail, the hot water flows from the process device in the coil, and the water is evenly sprinkled on the coil through the nozzle on the water distribution pipe, and then drips onto the filler, and finally falls into the water storage tank. The dry and cold air outside enters the tower from the air inlet on both sides of the cooling tower after being pumped by the fan. The dry low-humidity air exchanges heat with the water film formed when the hot water flows through the surface of the filler after heat exchange under the action of the top fan. The hot air with high humidity and high-humidity value is extracted from the top, and the cooling water drips into the water collection tank and is recycled again. When the water droplets come into contact with the air, on the one hand, due to the direct heat transfer between the air and the water, on the other hand, due to the pressure difference between the water vapor surface and the air, evaporation occurs under the action of pressure, and the heat in the water is taken away, that is, evaporation heat transfer, thereby achieving the purpose of cooling.

[0005] However, the cooling efficiency of existing closed cooling towers still needs to be improved. In addition, in hot weather, after the outside air enters the cooling tower, due to its own high temperature, the efficiency of heat exchange will be reduced, and the power energy consumed by the cooling tower will also increase. Therefore, it is necessary to improve the existing cross-flow closed cooling tower to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] like Figure 1 to Figure 5 As shown, this embodiment proposes a closed cooling tower, including a tower body 1 and an exhaust fan 2, a spray system 3, a coil 24, a filler 4 and a water storage tank 5 installed on the tower body 1 from top to bottom, and also includes:

[0041] The first mobile frame 6 is arranged in the tower body 1 for vertical movement.

[0042] The first mounting plate 7 is rotatably mounted on the first moving frame 6.

[0043] The second mobile frame 8 is arranged in the tower body 1 for vertical movement. The second mobile frame 8 and the first mobile frame 6 are located on two sides of the tower body 1 relative to each other, and the movement directions of the second mobile frame 8 and the first mobile frame 6 are opposite.

[0044] The second mounting plate 9 is rotatably arranged on the second moving frame 8 . The first mounting plate 7 and the second mounting plate 9 rotate in opposite directions. There are two fillers 4 , one is arranged on the first mounting plate 7 , and the other is arranged on the second mounting plate 9 .

[0045] Furthermore, the first mobile frame 6 has two opposite first connecting parts 10 , and there are two first mounting plates 7 , which are respectively arranged on the two first connecting parts 10 , and one filler 4 is arranged between the two first mounting plates 7 .

[0046] In this embodiment, in order to solve the problem that the cooling efficiency of the closed cooling tower in the prior art is not high enough, the inventor has improved the existing closed cooling tower, and designed the filler 4 to be movable up and down, and to rotate when moving. The fillers 4 are two on the left and right, and the two fillers 4 on the left and right move in opposite directions, and the rotation directions are also opposite. The fillers 4 are installed vertically upward, and the rotation angle range of the fillers 4 is controlled to be 0° to 30°, 0° is a vertical state, when the filler 4 on the left moves to the highest position, its angle is 30°, at this time the filler 4 on the right moves to the lowest position, its angle is also 30°, and the inclination states of the two fillers 4 are It gradually moves away from the inner wall of the tower body 1, that is, at this time, the water flowing down from the side ridges of the upper filler 4 can drip into the side ridges of the lower filler 4, and then the two fillers 4, one descending and the other ascending, are in a vertical state when they meet in the middle, without interference, and do not affect their respective lifting and lowering. After that, they will continue to rotate during the lifting and lowering, and after reaching the lowest position and the highest position respectively, they will be inclined at 30°, so that the falling water can flow between the side ridges of the two fillers 4, and finally drip into the water storage tank 5, thereby lengthening the residence time of the water, and the continuous flow between the side ridges of the two fillers 4 can also accelerate its cooling. Long-term use can greatly improve the cooling efficiency of the cooling tower.

[0047] Specifically, the inventor installed a set of devices for driving the filler 4 to move and rotate on the left and right inner walls of the tower body 1. Taking the left side as an example, a movable frame that can be raised and lowered is installed on the inner wall, namely the first movable frame 6. The first movable frame 6 can be raised and lowered on the slide rail through a slider. The slide rail can be directly installed on the inner wall, and the first movable frame 6 is pushed by a cylinder or an electric push rod. From a top view, the shape of the first movable frame 6 is similar to a C-shape, and has two connecting rods at both ends, namely the first connecting part 10. A rotating plate, namely the first mounting plate 7, is installed on each end of the first connecting part 10. The first mounting plate 7 can be installed on the first connecting part 10 through a rotating shaft and driven by an electric motor. Then the filler 4 is installed between the two first mounting plates 7. The filling 4 can be controlled to rise and fall while rotating at a certain rate through programs and sensors. The movement trajectory of the movable frame on the right inner wall is just opposite to that of the first movable frame 6, and the rotation trajectory of the rotating plate is also just opposite, that is, when the left filler 4 is at the highest position, it is tilted 30° to the right, and the right filler 4 is at the lowest position and tilted 30° to the left. When the two fillers 4 meet in the middle, they are both 0°, that is, they are in a vertical state, and there is no interference. When the left filler 4 is at the lowest position, it continues to tilt 30° to the right, and when the right filler 4 is at the highest position, it tilts 30° to the left, that is, the lifting and rotation of the filler 4 are reciprocating motions, and this cycle allows water to continue to flow between the side ridges of the filler 4.

[0048] Furthermore, it also includes,

[0049] There are four first mounting blocks 11, which are arranged in pairs on the two first mounting plates 7. Each first mounting block 11 has a first slideway 12.

[0050] There are four first sliding blocks 13, which are respectively set in the four first slideways 12.

[0051] There are eight first limit blocks 14 , four of which are respectively arranged on the four first sliding blocks 13 , and the other four are respectively arranged on the end surfaces of the four first mounting blocks 11 , and one filler 4 is stuck between the eight first limit blocks 14 .

[0052] In this embodiment, the inventor also designed a first mounting block 11 on the first mounting plate 7, and a first slide 12 is opened on the first mounting block 11, a first slider 13 is installed in the first slide 12, and a first limit block 14 is installed on the first slider 13, and there are four such first mounting blocks 11, which are distributed in pairs on the two first mounting plates 7, and four more first limit blocks 14 are arranged on the end face of the first mounting block 11. The eight first limit blocks 14 can clamp the eight corners of the filler 4, and the height of the clampable filler 4 can be adjusted by the first slider 13 to adapt to fillers 4 of different sizes.

[0053] Furthermore, it also includes,

[0054] There are four first fixing bolts 15 , which are respectively disposed in the four first slideways 12 to fix the four first mounting blocks 11 on the two first mounting plates 7 .

[0055] In this embodiment, the inventor further installs a first fixing bolt 15 in the first slideway 12, which can not only fix the first mounting block 11 on the first mounting plate 7, but also limit the first sliding block 13 to prevent it from falling off.

[0056] Furthermore, the second mobile frame 8 has two opposite second connecting parts 16 , and there are two second mounting plates 9 , which are respectively arranged on the two second connecting parts 16 , wherein the two fillers 4 are arranged between the two second mounting plates 9 .

[0057] Furthermore, it also includes,

[0058] There are four second mounting blocks 17, which are arranged in pairs on the two second mounting plates 9. Each second mounting block 17 has two second slideways 18.

[0059] There are four second sliding blocks 19, which are respectively set in the four second slideways 18.

[0060] There are eight second limit blocks 20 , four of which are respectively arranged on the four second sliding blocks 19 , and the other four are respectively arranged on the end surfaces of the four second mounting blocks 17 , wherein two fillers 4 are clamped between the eight second limit blocks 20 .

[0061] Furthermore, it also includes,

[0062] There are four second fixing bolts 21 , which are respectively disposed in the four second slideways 18 to fix the four second mounting blocks 17 on the two second mounting plates 9 .

[0063] In this embodiment, the structural design of the right side is the same as that of the left side.

[0064] Furthermore, it also includes,

[0065] The waterwheel 22 is disposed in the water storage tank 5 . The tower body 1 further comprises an air inlet 23 . The air inlet 23 is located above the water storage tank 5 . The waterwheel 22 is located at one side of the air inlet 23 .

[0066] In this embodiment, the inventor also installed a water wheel 22 near the air inlet 23 of the water tank 5. The water wheel 22 is driven by an external drive to lift the cooling water in the water tank 5, thereby reducing the temperature of the wind entering the air inlet 23, further improving the cooling efficiency of the cooling tower.

[0067] Example 2

[0068] The difference between this embodiment and embodiment 1 is that the left and right fillers are designed to be raised and lowered synchronously, that is, the left and right fillers are kept at the same level and raised and lowered at the same time, and the gap between the left and right fillers is adjusted to avoid interference.

[0069] The spray system 3 is controlled to spray water intermittently. The specific process is that when the ambient temperature is low, only air cooling can be enabled, that is, the spray system 3 is in a closed state. After the ambient temperature rises, the spray system 3 is gradually turned on, so that air cooling and water cooling work together to enhance the cooling. This design can reduce the energy consumption of the water pump. In addition, the air inlet 23 and the filler 4 can be staggered to reduce wind resistance, increase air volume, save energy consumption, and improve cooling efficiency.

[0070] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
