[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] like Figures 1-3 As shown, an energy recovery and utilization circulating water cooling tower in this embodiment includes a cooling tower body 1, both the upper and lower ends of the cooling tower body 1 are open, multiple air inlets 2 are provided on the lower side wall of the cooling tower body 1, support columns 3 are fixedly installed at the bottom of the cooling tower body 1, a circulating water recovery seat 6 is fixedly connected to the lower opening of the cooling tower body 1, a spray rod 4 is inserted into the cooling tower body 1, and multiple spray heads 401 are evenly distributed at the lower end of the spray rod 4. The feature is that a lower heat exchanger 5 is fixedly installed below the spray rod 4 inside the cooling tower body 1, and an upper heat exchange assembly is fixedly installed above the spray rod 4 inside the cooling tower body 1.

[0035] This application provides a circulating water cooling tower that can convert the heat energy of circulating water into other media for recycling and reuse. This solves the problem in the prior art where circulating water cooling towers directly discharge the heat of evaporated steam to the outside, failing to recover, store, or reuse the released heat energy, resulting in unnecessary energy waste. The overall idea of ​​this embodiment to solve the above problem is as follows: by setting a lower heat exchanger 5 that can contact the circulating water sprayed by the spray bar 4 through the spray head 401, an initial heat exchange is generated, allowing the lower heat exchanger 5 to exchange and recover the heat energy of the liquid circulating water. At the same time, the liquid circulating water can impact the lower heat exchanger 5 to generate splash, promoting the release of its heat energy. After the liquid circulating water is sprayed out through the spray head 401, hot steam will be generated. The hot steam moves upward and comes into contact with the upper heat exchange component for a second heat exchange, allowing the upper heat exchange component to exchange and recover the heat energy of the hot steam. At the same time, the emission temperature of the hot steam is reduced, reducing the impact of a large amount of hot steam emission on the surrounding environment.

[0036] like Figure 3 , Figure 7 and Figure 8As shown, the lower heat exchanger 5 is composed of an outer water storage frame and longitudinal heat exchange pipes 501, transverse heat exchange pipes 502 and diffusion heat exchange pipes 503. There are three lower heat exchangers 5, which are vertically and uniformly distributed.

[0037] As an embodiment, the lower heat exchanger 5 can receive the circulating water sprayed by the spray rod 4 through the spray head 401. The circulating water containing heat can be in sufficient contact with the lower heat exchanger 5 to complete heat exchange, increase the residence time of the circulating water and promote the heat release effect of the circulating water.

[0038] As shown in Figure 3 , Figure 4 and Figure 5 , the upper heat exchange assembly is composed of an upper heat exchange tank 7, an upper flow guide pipe 701 and a lower flow guide pipe 702. The upper flow guide pipe 701 and the lower flow guide pipe 702 are fixedly installed on the periphery of the upper heat exchange tank 7. The upper heat exchange tank 7 is fixedly installed in the central part of the cooling tower body 1 through the upper flow guide pipe 701 and the lower flow guide pipe 702.

[0039] As an embodiment, the upper heat exchange tank 7 can store a proper amount of heat recovery medium. When the circulating water sprayed by the spray rod 4 through the spray head 401 contacts with air, hot steam is generated. When the hot steam moves upward, it can contact with the upper flow guide pipe 701 and the lower flow guide pipe 702 to complete heat exchange, so that the heat recovery medium in the upper flow guide pipe 701 and the lower flow guide pipe 702 can temporarily store the heat energy.

[0040] As shown in Figure 1 , Figure 5 and Figure 6 , the heat energy recovery tank 704 is sleeved on the periphery of the cooling tower body 1. The upper flow guide pipe 701 and the lower flow guide pipe 702 are inserted into the heat energy recovery tank 704.

[0041] As an embodiment, the heat energy recovery tank 704 can be connected with the upper flow guide pipe 701 and the lower flow guide pipe 702. After completing heat exchange, the heat recovery medium in the upper flow guide pipe 701 and the lower flow guide pipe 702 can flow into the heat energy recovery tank 704 for storage, so as to ensure the stable storage effect of the heat energy and avoid heat energy dissipation.

[0042] As shown in Figure 3 , Figure 5 and Figure 6 , the upper flow guide pipe 701 and the lower flow guide pipe 702 are fixedly installed with heat conduction fins 703 on the upper and lower sidewalls. There are multiple groups of heat conduction fins 703.

[0043] As an implementation form, the heat-conducting fins 703 can increase the contact area between the upper and lower flow guide pipes 701 and 702 and the hot steam, thereby enhancing the heat exchange effect of the upper and lower flow guide pipes 701 and 702, and reducing the loss speed of the hot steam, and promoting the heat energy recovery effect.

[0044] As shown in Figure 1 , Figure 3 and Figure 5 , the upper end of the upper heat exchange tank 7 is inserted with a water injection pipe 705;

[0045] As an implementation form, the upper heat exchange tank 7 can inject an appropriate amount of heat energy recovery medium through the water injection pipe 705.

[0046] As shown in Figure 4 and Figure 6 , the cooling tower body 1 is fixedly connected with a driving motor 8 below the upper heat exchange assembly, and the driving motor 8 is fixedly connected with a fan 801 at the transmission output end;

[0047] As an implementation form, the driving motor 8 can drive the fan 801 to rotate, so that the rotating fan 801 can drive the surrounding air to flow upwards, so that the air at the lower end of the cooling tower body 1 can enter the cooling tower body 1 through the air inlet window 2 and flow upwards, forming an air flow, promoting the contact effect between the circulating water liquid and the air, and improving the heat energy release effect of the circulating water liquid.

[0048] The specific implementation process of the embodiment is as follows: in use, the driving motor 8 can drive the leaf fan 801 to rotate, so that the rotating leaf fan 801 can drive the surrounding air to flow upwards, and the circulating water can flow into the cooling tower body 1 through the spraying rod 4 and be released in the cooling tower body 1 through the spraying head 401. The sprayed circulating water will contact the flowing air, release heat energy, produce hot steam, and the circulating water will contact the lower heat exchanger 5, produce heat exchange, recover the heat energy of the liquid circulating water, and at the same time, the splashing and diffusing effect is generated when the circulating water falls on the lower heat exchanger 5, the air time is increased, the heat release effect is promoted, more hot steam is generated, the multi-layer distributed lower heat exchanger 5 can fully recover the heat energy of the circulating water and promote the overall heat release effect of the circulating water, the circulating water passing through the lower heat exchanger 5 will enter the circulating water recovery seat 6 for recycling and reuse, and the hot steam will contact the upper heat exchange assembly during the rising process. The heat energy recovery medium in the upper heat exchange tank 7 can flow into the upper and lower flow guide pipes 701 and 702 to complete diffusion, and the heat conduction fins 703 can greatly increase the contact area of the upper and lower flow guide pipes 701 and 702 with the hot steam, improve the heat exchange effect, and slow down the release speed of the hot steam, further promote the heat energy recovery effect, and the hot steam after heat exchange will be released, and the heat energy recovery medium after heat exchange can flow into the heat energy recovery tank 704 for storage.
