[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] According to an embodiment of the utility model, a multi-tank dual-medium cooling tower is provided. Figures 1 to 4, including: a first water pipe 11 and a second water pipe 12; a first filler area 21 and a second filler area 22; a first water collecting tank 3, the first water pipe 11, the first filler area 21 and the first water collecting tank 3 are arranged correspondingly, and the first water collecting tank 3 is provided with a return pipe 31; a second water collecting tank 4, the second water pipe 12, the second filler area 22 and the second water collecting tank 4 are arranged correspondingly, and the second water collecting tank 4 is provided with a first outlet 41 and a second outlet 42, the first outlet 41 is arranged correspondingly to the first water collecting tank 3, and a filter membrane 5 is arranged on the first outlet 41; a third water collecting tank 6, the third water collecting tank 6 is arranged correspondingly to the second outlet 42, the working medium in the second water collecting tank 4 flows into the third water collecting tank 6 through the second outlet 42, the third water collecting tank 6 contains heat transfer modification additives, and the third water collecting tank 6 is provided with a circulating pump 61, and the circulating pump 61 is connected to the second water pipe 12. The multi-tank dual-working medium cooling tower of this embodiment includes two systems, one is the first working medium cooling system, and the other is the second working medium cooling system. The first water pipe 11 and the second water pipe 12 are both connected to the high-temperature water pipe outside the cooling tower. The first working medium is pure water. The high-temperature first working medium in the equipment enters through the first water pipe 11 of the cooling tower, and undergoes heat exchange in the first filler area 21 to become the low-temperature first working medium. After heat exchange, it enters the first water collection tank 3 and returns to the relevant equipment through the return pipe 31 to ensure the normal operating temperature of the equipment system and circulate cooling. The second working medium is a mixed liquid composed of a heat transfer modification additive and the first working medium. The heat transfer modification additive is nanoparticles such as aluminum oxide, copper oxide, iron oxide, and silicon carbide. The second working fluid in the third water collecting tank 6 is pumped into the second water pipe 12 by the suction action of the circulating pump 61, and the high-temperature first working fluid connected by the equipment converges and mixes with the second working fluid in the second water pipe 12 to form a high-temperature and low-concentration second working fluid. After contact heat exchange in the second filling area 22, it is converted into a low-temperature and low-concentration second working fluid, and then converges to the second water collecting tank 4. In the second water collecting tank 4, it is filtered and separated by the filter membrane 5 on the first outlet 41, and the precipitated first working fluid flows into the first water collecting tank 3 through the first outlet 41, thereby realizing the cold recovery of the second working fluid. Due to water loss, the second working medium with low temperature and high concentration is formed in the second water collection tank 4 and flows into the third water collection tank 6 through the second outlet 42. At this time, the airflow in the tower is subjected to low evaporation pre-cooling treatment. Due to the characteristics of the heat transfer modification additive itself, the evaporation of the heat transfer modification additive at a high concentration is inhibited. When the airflow in the tower is subjected to evaporation pre-cooling treatment, the temperature in the tower drops, while the temperature of the heat transfer modification additive itself rises, so that the second working medium with low temperature and high concentration is converted into the second working medium with high temperature and high concentration. Finally, the second working medium with high temperature and high concentration is sent into the second water pipe 12 again through the circulation pump 61, so as to realize the self-circulation of the second working medium in the tower. A partition design is adopted between the first filling area 21 and the second filling area 22 to prevent the low-concentration second working medium from entering the first filling area 21 and contaminating the first working medium.The water collection pool of this embodiment adopts a multi-pool design, and the second working fluid is self-circulated in an independent tower, which avoids the risk of local aggregation and blockage of the heat transfer modification additive in the refrigeration pipeline, and solves the technical problem in the related technology that the heat transfer modification additive is easy to block the pipeline during long-term operation and affect the refrigeration system.

The first filling area 21 is in the middle of the cooling tower, the second filling area 22 is arranged around the first filling area 21, the first water pipe 11 and the second water pipe 12 are located at the top of the cooling tower, and the first working medium and the second working medium are subjected to gravity and enter the first water collecting tank 3 and the second water collecting tank 4 respectively through the first filling area 21 and the second filling area 22. The third water collecting tank 6 is located at the bottom of the tower for receiving the second working medium from the second water collecting tank 4.

[0029] See also Figure 1 The multi-tank dual-medium cooling tower of this embodiment further includes a flow guide assembly 7, which is located in the first water collecting tank 3, and a flow guide pipe 71 of the flow guide assembly 7 is connected to the first outlet 41. The flow guide pipe 71 serves as a bridge between the second water collecting tank 4 and the first water collecting tank 3, and transports the first working medium precipitated from the second water collecting tank 4 to the first water collecting tank 3.

[0030] See also Figure 1 and Figure 2 In the multi-tank dual-medium cooling tower of this embodiment, the flow guide assembly 7 also includes a manifold 72. There are multiple manifolds 71, one end of each manifold 71 is connected to the first outlet 41, and the other end of each manifold 71 is connected to the manifold 72. The working fluid entering each manifold 71 flows into the first water collecting tank 3 through the manifold 72. There are multiple first outlets 41, and each first outlet 41 is connected to each manifold 71. With the manifold 72 as the central axis, each manifold 71 is diffused toward the periphery, so that the first working fluid precipitated in the second water collecting tank 4 can quickly flow into the first water collecting tank 3.

[0031] See also Figure 1 and Figure 2In the multi-tank dual-medium cooling tower of this embodiment, the flow guide assembly 7 further includes a support column 73, and one end of the manifold 72 away from the flow guide 71 is connected to the support column 73, and the support column 73 is located in the first water collecting tank 3, and the support column 73 is used to support the manifold 72.

[0032] See also Figure 3 In the multi-tank dual-medium cooling tower of this embodiment, a first partition plate 43 is further provided in the second water collecting tank 4. One end of the first partition plate 43 is connected to the shell 8 of the multi-tank dual-medium cooling tower, and the other end of the first partition plate 43 is extended in the direction close to the guide pipe 71. The first partition plate 43 has an angle with the horizontal plane. The end of the first partition plate 43 close to the cooling tower shell 8 is high, and the end close to the first outlet 41 is low. The entire first partition plate 43 is in an inclined state. In this way, in the second water collecting tank 4, the low-temperature and low-concentration second working medium is affected by the first partition plate 43, and preferentially contacts the filter membrane 5 to separate, so as to precipitate the first working medium and flow into the first water collecting tank 3 from the guide pipe 71.

[0033] See also Figure 3 In the multi-tank dual-medium cooling tower of this embodiment, a second partition plate 44 is further provided in the second water collecting tank 4, and the second partition plate 44 is spaced apart from the first partition plate 43. One end of the second partition plate 44 is connected to the wall of the second water collecting tank 4, and the other end of the second partition plate 44 is extended toward the shell 8, and the second partition plate 44 is horizontally provided. The first partition plate 43 plays a role in preferentially precipitating the first working medium, and the second partition plate 44 plays a role in diverting and guiding the second working medium in the second water collecting tank 4, so that the low-temperature and high-concentration second working medium flows to the second outlet 42.

[0034] See also Figure 1 and Figure 2 In the multi-tank dual-medium cooling tower of this embodiment, an air inlet 81 is also provided on the shell 8, and the air inlet 81 is located between the second water collecting tank 4 and the third water collecting tank 6. The cooling fan 9 supplies air into the cooling tower, and the low-temperature and high-concentration second working medium forms a spray rain curtain on the vertical surface of the air inlet 81, and performs low-evaporation pre-cooling treatment on the airflow entering the tower. The high-concentration second working medium is affected by its own characteristics, and its evaporation is limited, and heat absorption from the environment is dominant, thereby becoming a high-temperature and high-concentration second working medium.

[0035] See also Figure 1 and Figure 2In the multi-tank dual-medium cooling tower of this embodiment, the first water pipe 11 is provided with a first nozzle 111, and the first nozzle 111 is multiple, and each first nozzle 111 is arranged at intervals; the second water pipe 12 is provided with a second nozzle 121, and the second nozzle 121 is multiple, and each second nozzle 121 is arranged at intervals; the second outlet 42 is provided with a third nozzle 421, and the third nozzle 421 is multiple, and each third nozzle 421 is arranged at intervals. Through the spraying treatment of each nozzle, the cooling effect is effectively reduced.

[0036] See also Figure 4 The multi-tank dual-medium cooling tower of this embodiment sets the optimal concentration C of the working medium containing the heat transfer modification additive. L2,0 According to the flow rate of the second water pipe 12 and the concentration in the third water collection tank 6, the flow rate of the circulating pump 61 is adjusted. The flow rate calculation method of the circulating pump 61 is: Among them, Q L1,2 is the flow rate of the second water pipe 12, C L2,1 is the concentration in the third water collection tank 6.

[0037] In the multi-tank dual-medium cooling tower of this embodiment, the flow rate Q of the second water pipe 12 is known. L1,2 , the concentration C in the third water collection tank 6 L2,1 When heat transfer modification additives are used to enhance the heat transfer capacity of the working fluid in the packing area, that is, the second working fluid, the trend of heat transfer capacity changing with concentration varies with the type of modification additives and the stabilization treatment method. It generally shows two types: first increase and then decrease, and first rapid increase and then slow increase. Therefore, there is an optimal concentration C of the working fluid of the heat transfer modification additive. L2,0 In order to enhance the stability of the heat transfer modification additive in the base liquid, a common stabilization treatment method is to add a surfactant. However, the use of a surfactant will weaken the thermal performance of the modification additive, reduce the surface tension of water, increase the evaporation rate, and increase the water loss. This embodiment adopts a surfactant-free functional treatment method. The evaporation rate of the second working fluid decreases with the increase of the concentration of the heat transfer modification additive. Therefore, a high concentration of C L2,1 It can effectively reduce the evaporation rate. Finally, after the flow and concentration balance calculation, the design flow rate of the circulation pump can be determined as Q L2,1 .

[0038] For the second water collection tank 4, according to the flow balance and concentration balance principles, we can get:

[0039] Q L2，0 =Q L2，1 +Q L1，3

[0040] Q L2，0 ·C L2， 0 = Q L2，1 ·C L2，1 +QL1，3 ·C L1，3

[0041] In the formula, Q L2，0 is the flow rate of the high-temperature, low-concentration second working fluid entering the second water collection tank 4, C L2，0 is the additive concentration of the working fluid; Q L2，1 is the flow rate of the low-temperature and high-concentration second working fluid leaving the second water collection tank 4 (entering the third water collection tank 6), C L2，1 is the additive concentration of the working fluid; Q L1，3 is the flow rate of the low-temperature first working fluid leaving the second water collection tank 4 (entering the first water collection tank 3), C L1，3 is the additive concentration of the working fluid.

[0042] Since the first working fluid does not contain heat transfer modification additives, C L1，3 The value of can be 0; at the same time, it is known that the inlet and outlet flow rates of the second working fluid cooling system are equal, that is, Q L1，3 =Q L1，2 , the above formula can be further written as:

[0043] Q L2，0 =Q L2，1 +Q L1，2

[0044] Q L2，0 ·C L2，0 =Q L2，1 ·C L2，1

[0045] Finally, the above formula can be combined to determine the design flow rate Q of the circulation pump: L2，1 :

[0046]

[0047] From the calculation formula, we can know that as the concentration C in the third water collection tank 6 increases, L2，1 Increase, the operating flow rate Q of the circulating pump 61 can be reduced accordingly L2，1 , thereby greatly reducing the energy efficiency of the circulating pump and improving the overall cooling efficiency of the cooling tower.

[0048] Inlet air precooling treatment: In order to realize the self-circulation of the second working fluid in the tower body, the most direct way is to circulate the low-temperature and high-concentration second working fluid in the third water collection tank 6. Although the circulation flow rate can be controlled at a low level, it will still cause cold reflux, and the low-temperature working fluid and the high-temperature working fluid will mix at the second water pipe 12, reducing the heat exchange temperature difference between the second working fluid and the airflow entering the tower, weakening the enhanced heat exchange effect. In this embodiment, this part of the cold capacity is fully utilized, and a spray rain curtain formed by a low-temperature and high-concentration second working fluid is set at the air inlet 81. Compared with the traditional partition-type isohumidification cooling precooling, since the evaporation rate of the high-concentration second working fluid is effectively suppressed, the airflow entering the tower can be precooled with low evaporation and high-efficiency direct contact in a hot outdoor environment. This can increase the heat exchange temperature difference between the airflow and the working fluid on the one hand, and is conducive to reducing the outlet water temperature on the other hand, and the heat exchange effect of the whole tower can be significantly improved.
