Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a high-position water tank type high-efficiency energy-saving cooling tower. Background Art

[0002] Cooling tower equipment is the core component of the circulating water field. As a heat exchange equipment, it is widely used in industrial production, power systems and other fields. Water is circulated through water pumps, plant heat exchangers and cooling towers. The power source of water circulation is the water pump. The cost of the circulating water system is mainly the power consumption of the water pump. The larger the water volume, the higher the head, and the greater the shaft power consumed by the water pump. Therefore, reducing the head of the water pump can achieve the purpose of reducing operating costs. Conventional cooling towers are above-ground pools or semi-underground pools. According to the U-tube principle, the head of the water pump is the height difference from the pool liquid surface to the heat exchanger inlet.

[0003] In the prior art, such as Figure 2 As shown, it includes a circulating water pump, a heat exchanger, a cooling tower, a cooling tower water sprinkling filler, a water pool No. 1 and a splashing device. The water pool No. 1 and the cooling tower are both arranged on the ground. The cooling tower is respectively provided with a splashing device and a cooling tower adjacent water filler. The output end of the water pool No. 1 is connected with the input end of the circulating water pump, the output end of the circulating water pump is connected with the input end of the heat exchanger, and the output end of the heat exchanger is connected with the input end of the splashing device. When in use, the circulating water pump is started, so that the water in the water pool No. 1 enters the heat exchanger for heat exchange, and then is sprayed into the cooling tower through the splashing device. At the same time, it is cooled down with the cooperation of the cooling tower adjacent water filler.

[0004] During use, due to the fixed height of the heat exchanger, there is a large difference between the liquid level of the water in the No. 1 water tank and the height of the heat exchanger, which increases the delivery head of the circulating water pump, increases the power of the circulating water pump, and further causes an increase in electricity costs. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a high-position water tank type high-efficiency energy-saving cooling tower which reduces power loss.

[0006] The utility model discloses a high-level water tank type high-efficiency energy-saving cooling tower, comprising a circulating water pump, a heat exchanger, a cooling tower, a cooling tower water sprinkling filler and a splashing device.

The water after heat exchange is sprayed downward through a splashing device and is quickly cooled with the cooperation of the cooling tower water spraying filler. Since the high-level water tank assembly reduces the height difference between the water and the heat exchanger, the delivery head of the circulating water pump is reduced, and the power used of the circulating water pump is further reduced, thereby achieving water circulation cooling and saving electric energy. At the same time, the distance between the water surface and the splashing device of the No. 2 water tank is increased, thereby reducing the noise generated by the water sprayed by the splashing device entering the No. 2 water tank.

[0007] Preferably, the high-level water tank assembly includes a No. 2 water tank and support columns, the support columns are installed on the support surface, and the top ends of the support columns are connected to the bottom end of the No. 2 water tank; multiple groups of support columns support the No. 2 water tank, thereby increasing the height of the No. 2 water tank, further reducing the height difference between the water level inside the No. 2 water tank and the heat exchanger, and reducing the delivery head of the circulating water pump.

[0008] Compared with the prior art, the utility model has the following beneficial effects: when in use, the circulating water pump is started, so that the water in the high-level water tank assembly is transported to the inside of the heat exchanger through the circulating water pump for heat exchange operation, and the water after heat exchange is sprayed downward through the splashing device, and is quickly cooled with the cooperation of the cooling tower water spraying filler. Since the high-level water tank assembly reduces the height difference between the water and the heat exchanger, the delivery head of the circulating water pump is reduced, and the power used of the circulating water pump is further reduced, so that water circulation cooling is achieved while saving electric energy.

[0012] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively below with reference to the relevant drawings. The utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0013] Example

[0014] like Figure 1 As shown, a high-level water tank type high-efficiency energy-saving cooling tower of the utility model comprises a circulating water pump 1, a heat exchanger 2, a cooling tower 3, a cooling tower water spraying filler 4 and a splashing device 8, the circulating water pump 1 and the cooling tower 3 are arranged on the supporting surface 9, the splashing device 8 and the cooling tower water spraying filler 4 are arranged on the cooling tower 3, and also comprises a high-level water tank assembly, the high-level water tank assembly is arranged on the supporting surface 9, the high-level water tank assembly is directly below the cooling tower 3, the output end of the high-level water tank is connected to the input end of the circulating water pump 1, the output end of the circulating water pump 1 is connected to the input end of the heat exchanger 2, and the output end of the heat exchanger 2 is connected to the input end of the splashing device 8;

[0015] The high-level water tank assembly includes a No. 2 water tank 6 and a support column 7 . The support column 7 is installed on a support surface 9 , and the top ends of the support columns 7 are connected to the bottom ends of the No. 2 water tank 6 .

[0016] In this embodiment, when in use, the circulating water pump 1 is started, so that the water in the No. 2 water pool 6 is transported to the inside of the heat exchanger 2 through the circulating water pump 1 for heat exchange operation. The water after heat exchange is sprayed downward through the splashing device 8, and is quickly cooled with the cooperation of the cooling tower water spraying filler 4. Since the high-level water pool component reduces the height difference between the water and the heat exchanger 2, the delivery head of the circulating water pump 1 is reduced, and the use power of the circulating water pump 1 is further reduced, so that water circulation cooling is achieved while saving electric energy. At the same time, the No. 2 water pool 6 increases the distance between the water surface and the splashing device 8, thereby reducing the noise generated by the water sprayed by the splashing device 8 entering the No. 2 water pool 6. The circulating water pump 1 is placed directly below the No. 2 water pool 6. This design method does not require the construction of a separate pump room. A simple analysis is performed through calculation. Figure 2 The minimum head of the medium circulating water pump 1 is H = Ha-Hc, where ha is the height of the heat exchanger, Hc is the height of the liquid level of the No. 1 water tank, and H is the distance from the liquid level of the No. 1 water tank to the heat exchanger 2. Figure 2 The No. 2 water tank 6 is lifted by the support column 7, and the minimum head of the circulating water pump 1 is H”=Ha-Hc”, where Hc” is the liquid level height of the No. 2 water tank. By comparing, H” is less than H, so it can be concluded that the head of the circulating water pump 1 is greatly reduced.

[0017] The utility model relates to a high-position water tank type high-efficiency energy-saving cooling tower. The circulating water pump 1, the heat exchanger 2, the cooling tower 3, the cooling tower water sprinkling filler 4 and the splashing device 8 are purchased on the market. The technicians in the industry only need to install and operate them according to the accompanying instruction manual, without the need for the technicians in this field to make creative labor.

[0018] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
