DETAILED DESCRIPTION

[0030] The application will be further described below in combination with the drawings and examples.

[0031] An energy-saving closed spray system, as shown in Figure 1 and Figure 2 , comprises a chemical cooling tower body 1, a water inlet pipe 2, a water pipe 3, a first spray head 4, a rotating mechanism 5 and a heat exchange mechanism 6, the water inlet pipe 2 is connected inside the chemical cooling tower body 1, six water pipes 3 are rotationally connected to the upper part of the water inlet pipe 2, three first spray heads 4 are rotationally connected to each water pipe 3, the rotating mechanism 5 is arranged at the top of the chemical cooling tower body 1, and the heat exchange mechanism 6 is arranged on the water inlet pipe 2.

[0032] It should be noted that when it is necessary to cool the high-temperature cooling water so that the cooling water can be recycled, the device can be used to cool the high-temperature cooling water. First, the high-temperature cooling water is introduced into the chemical cooling tower body 1 through the water inlet pipe 2, then the high-temperature cooling water is introduced through the water pipe 3, and then the high-temperature cooling water is sprayed through the first spray head 4. During the spraying process, the rotating mechanism 5 is started to spray slowly, the spraying heat exchange efficiency is improved, the sprayed high-temperature cooling water is in contact with dry cold air, so that evaporation cooling is realized, and the generated hot and humid air is discharged through the upper part of the chemical cooling tower body 1. At the same time, when the high-temperature cooling water enters the water inlet pipe 2, the heat exchange mechanism 6 is used to preliminarily perform heat exchange treatment, so as to further improve the heat exchange efficiency of the subsequent high-temperature cooling water.

[0033] As shown in Figure 2 and Figure 3As shown, the rotating mechanism 5 comprises a fixed frame 51, a control motor 52, a speed reducer assembly 53, a rotating shaft 54 and a gear 55. The fixed frame 51 is connected between the left and right sides of the upper part of the chemical cooling tower body 1. The control motor 52 is connected to the upper left part of the fixed frame 51 through bolts. The output shaft of the control motor 52 is connected with the speed reducer assembly 53. The speed reducer assembly 53 comprises a fixed seat and a gearbox. The fixed seat is connected to the upper left part of the fixed frame 51. The gearbox is connected to the fixed seat. The speed reducer assembly 53 is connected with the rotating shaft 54 at the bottom. The rotating shaft 54 passes through the fixed frame 51. The gear 55 is connected to the position where the top of the water pipe 3 passes through the lower part of the fixed frame 51. The gear 55 is also connected to the lower part of the rotating shaft 54. The gears 55 are meshed with each other.

[0034] It should be noted that when the high-temperature cooling water is sprayed for cooling, the control motor 52 can be started. The output shaft of the control motor 52 drives the speed reducer assembly 53 to start running, so that the rotating shaft 54 starts to rotate at a low speed. In this process, the adjacent gear 55 is driven by the rotating shaft 54 to rotate at a low speed, so that the gear 55 at the top of the water pipe 3 starts to rotate at a low speed. At this time, the water pipe 3 will rotate at a low speed under the drive of the adjacent gear 55, so that the high-temperature cooling water is sprayed at a low speed, so that the high-temperature cooling water can fully contact with the dry cold air and be cooled. When the cooling process is completed, the control motor 52 is turned off. In summary, the output shaft of the control motor 52 drives the speed reducer assembly 53 to rotate, so that the rotating shaft 54 drives the gear 55 to rotate at a low speed. At this time, the water pipe 3 will rotate at a low speed and spray the high-temperature cooling water at a low speed, so that the high-temperature cooling water can fully contact with the dry cold air to complete the cooling, thereby improving the cooling efficiency.

[0035] As shown in Figure 2 and Figure 4 The heat exchange mechanism 6 comprises a first connecting piece 61, a mounting column 62 and a heat exchange fin 63. The first connecting piece 61 is connected to the water pipe 3. The upper part of the first connecting piece 61 is annular and the lower part is L-shaped. The mounting column 62 is connected between the first connecting pieces 61. The mounting column 62 is attached to the water inlet pipe 2. The mounting column 62 is uniformly connected with twelve heat exchange fins 63 distributed above and below. The heat exchange fins 63 are used to assist the high-temperature cooling water in heat exchange process.

[0036] It needs to be explained that when the high-temperature cooling water is cooled and circulated, as the high-temperature cooling water is transported upwards through the water inlet pipe 2, the rotation of the water pipe 3 will drive the first connecting piece 61 to rotate, and then the mounting column 62 drives the heat exchange fin 63 to rotate. At this time, since the mounting column 62 is tightly attached to the water inlet pipe 2, when the high-temperature cooling water passes through, it can first enter the heat exchange state under the effect of the heat exchange fin 63, thereby discharging part of the heat and further improving the cooling efficiency. As described above, the first connecting piece 61 is driven to rotate by the water pipe 3, so that the mounting column 62 drives the heat exchange fin 63 to rotate, and then the high-temperature cooling water can be first heat-exchanged by the heat exchange fin 63 after entering the water inlet pipe 2, thereby discharging part of the heat and further improving the cooling efficiency.

[0037] As shown in Figure 2 and Figure 5 It also includes a swing mechanism 7, which includes a fixed rod 71, a stop rod 72, a fixed piece 73, a fixed block 74, and a spring 75. The outer edges of the lower part of the fixed frame 51 are uniformly connected with six fixed rods 71, and the fixed rods 71 correspond to the water pipes 3 respectively. The top of the first spray head 4 is connected with a stop rod 72, which can be pushed by the adjacent fixed rod 71. Three fixed pieces 73 are connected to the water pipes 3 respectively, and a fixed block 74 is connected to the first spray head 4. The fixed block 74 is slidingly connected with the adjacent fixed piece 73, and the spring 75 is connected between the fixed block 74 and the adjacent fixed piece 73.

[0038] It needs to be explained that as the water pipe 3 starts to rotate, the stop rod 72 will start to move counterclockwise, and at this time the stop rod 72 will be extruded and pushed by the adjacent fixed rod 71, so that the stop rod 72 rotates, and the first spray head 4 drives the fixed block 74 to rotate. At this time, the fixed block 74 will slide under the guidance of the fixed piece 73, and the adjacent spring 75 will be stretched under stress. As the stop rod 72 is separated from the adjacent fixed rod 71, the adjacent fixed block 74 drives the corresponding first spray head 4 to rotate and reset under the action of the spring 75, so that the stop rod 72 moves and resets. In this process, the first spray head 4 rotates by an angle of sixty degrees, thereby performing swing spraying, so that the high-temperature cooling water and dry cold air are more fully contacted.

[0039] As described above, the fixed rod 71 pushes the stop rod 72, which drives the adjacent first spray head 4 to deflect by an angle, thereby achieving the effect of swing spraying during rotation spraying, so that the high-temperature cooling water can be more fully contacted with the dry cold air, and the spraying range is increased to avoid accumulation and heat dissipation.

[0040] As shown in Figure 2 and Figure 6As shown, the device also comprises a water removal mechanism 8, which comprises a connecting frame 81, a sliding frame 82, a second connecting piece 83 and a limiting column 84. The upper part of the water inlet pipe 2 is connected with the connecting frame 81, the front part of the connecting frame 81 is provided with a protruding frame with wedge structure, the non-adjacent sides of the heat exchange fins 63 are connected with the limiting columns 84, the sliding frames 82 are slidingly connected between the limiting columns 84 on the same side, the sliding frames 82 are used for removing water from the heat exchange fins 63, the second connecting pieces 83 are connected between the bottoms of the sliding frames 82 on the same heat exchange fin 63, and the second connecting pieces 83 can be contacted and pushed by the connecting frame 81.

[0041] It should be noted that, as the water inlet pipe 3 drives the heat exchange fins 63 to start rotating, the sliding frames 82 drive the second connecting pieces 83 to move in a circular motion. As the second connecting pieces 83 contact the protruding frame on the connecting frame 81, the corresponding second connecting pieces 83 start to move upward, so that the corresponding sliding frames 82 start to slide upward. As the sliding frames 82 start to slide upward, the water on the adjacent heat exchange fins 63 is scraped off, so as to avoid the water from adhering to the heat exchange fins 63, which reduces the heat exchange effect. It should be particularly noted that, during the sliding process of the sliding frames 82, the limiting columns 84 guide the adjacent sliding frames 82 to slide stably.

[0042] In summary, the second connecting pieces 83 are pushed and extruded by the connecting frame 81, so that the corresponding sliding frames 82 slide, thereby wiping off the water on the adjacent heat exchange fins 63, avoiding the water from adhering to the heat exchange fins 63, which affects the heat exchange efficiency of the heat exchange fins 63.

[0043] As shown in Figure 2 and Figure 7 The device also comprises a disinfection mechanism 9, which comprises a guide seat 91, a guide pipe 92 and a second spray head 93. The upper sides of the left and right parts of the fixed frame 51 are connected with two guide seats 91, the guide seats 91 are provided with rib frames for improving the supportability, the guide pipe 92 is connected between the guide seats 91, the rear part of the guide pipe 92 penetrates through the chemical cooling tower body 1, and the left and right lower sides of the guide pipe 92 are connected with the second spray heads 93.

[0044] It should be noted that, in order to avoid that the high-temperature cooling water contains a large amount of bacterial impurities, the guide pipe 92 can be connected with an external device during the spraying process, so that the disinfectant is introduced into the guide pipe 92, and then the disinfectant is sprayed by the second spray head 93, thereby realizing disinfection treatment.

[0045] As shown in Figure 2 and Figure 8As shown, the chemical cooling tower body 1 further comprises a ventilation mechanism 10, which comprises a mounting frame 101, a fan motor 102 and a fan blade 103.

[0046] It should be noted that in order to improve the air circulation effect in the chemical cooling tower body 1, the fan motor 102 can be directly started to drive the fan blade 103 to rotate, thereby ensuring the air circulation in the chemical cooling tower body 1 and avoiding the accumulation of heat in the chemical cooling tower body 1.

[0047] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
