Description

Technical Field

[0001] This utility model relates to a composite flow cooling tower with adjustable air inlet position, belonging to the field of cooling tower technology. Background Technology

[0002] In existing technologies, closed-loop cooling towers generally have a fixed air inlet position and a fixed airflow direction inside the cooling tower. They cannot be adjusted according to different operating conditions in summer and winter, resulting in poor applicability and ineffective heat exchange efficiency to meet different operating conditions. Utility Model Content

[0003] This invention proposes a composite flow cooling tower with adjustable air inlet position, which aims to overcome the above-mentioned shortcomings of the existing technology and achieve good heat exchange efficiency in both summer and winter operating conditions.

[0004] The technical solution of this utility model is as follows: A composite flow cooling tower with adjustable air inlet position, the structure of which includes a tower body, inside which are coolers distributed on the left and right sides, each cooler having a water inlet and an outlet. Closable air inlet grilles are respectively installed on the outer sides of the tower body of the two coolers. Spray systems are respectively installed on the upper part of the two coolers, and closable air inlet grilles are respectively installed on the tower body above the two spray systems. Water collection tanks are respectively installed on the lower part of the two coolers, and the two water collection tanks are respectively connected to the corresponding spray systems through spray pipes passing through spray pumps. Water spraying packing is respectively installed between the two spray systems and the coolers. Closable air inlet grilles are respectively installed on the tower body outside the two water spraying packing. An air outlet is located at the center of the top of the tower body between the two spray systems, and a fan is installed inside the air outlet. Below the fan is the gap between the two water spraying packings and the two coolers inside the tower body.

[0005] During summer operation, open the closable air inlet grilles at the spray system and cooler, and close the closable air inlet grille at the water spray packing. The air entering the spray system comes into contact with the spray water and passes through the water spray packing to further reduce the spray water temperature, thus improving the heat exchange efficiency of the cooler. The air entering the cooler ensures that the spray water completely surrounds the heat exchange tubes, eliminating "dry spots" and maximizing the utilization of the heat exchange area, thereby improving the overall performance.

[0006] During winter operation, open the closable air inlet grille at the water-spraying packing, and close the closable air inlet grilles at the spray system and cooler. The air entering through the water-spraying packing passes through two channels—one for the air and one for the spray water—reducing the spray water temperature and improving the cooler's heat exchange efficiency. Because of the lower winter temperatures, the air does not directly contact the spray water, achieving a cooling effect and reducing drift.

[0007] Preferably, the water collection tank is provided with an overflow outlet, a drain outlet, and a water inlet.

[0008] The advantages of this utility model are: the structure is reasonably designed, and the direction of the air in the tower can be adjusted according to summer or winter operating conditions by opening or closing the grilles at each air inlet position, so as to ensure high heat exchange efficiency under both operating conditions.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0015] like Figure 1-4 As shown, a composite flow cooling tower with adjustable air inlet position includes a tower body 1. Inside the tower body 1 are coolers 2 distributed horizontally. Each cooler 2 has a water inlet 10 and a water outlet 11. Closable air inlet grilles 7 are respectively installed on the outer sides of the tower body 1 of the two coolers 2. A spray system 3 is installed on the upper part of each cooler 2. Closable air inlet grilles 7 are also installed on the tower body 1 above the spray systems 3. A water collection trough 6 is respectively installed on the lower part of each cooler 2, and an overflow outlet is provided on the water collection trough 6. The tower body 1 on both sides has a water inlet 12, a drain outlet 13 and a water supply outlet 14. The water collection tanks on both sides 6 are connected to the corresponding spray system 3 through the spray pipes 4 of the spray pump 5. Water spraying packing 9 is provided between the spray system 3 on both sides and the cooler 2. The tower body 1 on the outside of the water spraying packing 9 on both sides is provided with a closable air inlet grille 7. The center of the top of the tower body 1 between the spray system 3 on both sides is provided with an air outlet 15. A fan 8 is installed in the air outlet 15. The gap between the water spraying packing 9 on both sides and the cooler 2 on both sides is located below the fan 8.

[0016] During operation, the heat medium enters the cooler 2 through the inlet 10 for circulation and cooling. The cooler 2 exchanges heat with the heat medium. At the same time, the cooling water in the water collection tank 6 enters the spray system 3 through the spray pipe 4 under the action of the spray pump 5. After being cooled by the water spraying packing 9, the cooling water is evenly sprayed on the surface of the cooler 2 for heat exchange.

[0017] like Figure 1 As shown, during summer operation, the closable air inlet grilles 7 at spray system 3 and cooler 2 are opened, while the closable air inlet grille 7 at the water spray packing 9 is closed. The air entering through spray system 3 comes into contact with the spray water and passes through the water spray packing 9, further reducing the spray water temperature and improving the heat exchange efficiency of cooler 2. The air entering through cooler 2 ensures that the spray water completely surrounds the heat exchange tubes of cooler 2, eliminating "dry spots" and maximizing the utilization of its heat exchange area, thus improving performance.

[0018] like Figure 2 As shown, during winter operation, the closable air inlet grille 7 at the water-spraying packing 9 is opened, while the closable air inlet grilles 7 at the spray system 3 and the cooler 2 are closed. The air entering through the water-spraying packing 9 passes through two channels—one for the air and one for the spray water—reducing the temperature of the spray water and improving the heat exchange efficiency of the cooler 2. Because the winter climate is low, the cooling effect is achieved even without direct contact between the incoming air and the spray water, further reducing the drift rate.

[0019] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0020] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
