Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to an energy-saving and environmentally friendly cooling tower. Background Technology

[0002] Cooling towers, as an important heat dissipation device, are widely used in many fields such as industrial production and air conditioning. Their working principle is mainly based on the heat exchange between water and air to generate steam. Through evaporative heat dissipation, convective heat transfer and radiative heat transfer, the residual heat generated in industry or refrigeration and air conditioning is dissipated, thereby reducing the water temperature and ensuring the normal operation of the system.

[0003] A search revealed a patent, CN218627836U, which discloses an energy-saving and environmentally friendly cooling tower. The tower includes a housing with a controller connected to the top of the front side via screws, and a water inlet pipe extending through the top of the front side. This invention offers the advantages of coordinating air cooling of the pipes and refrigerating the cooling water, thus improving heat dissipation efficiency. It addresses the problems of existing energy-saving and environmentally friendly cooling towers, which mostly rely on simple spraying to dissipate heat from the pipes. In these towers, the cooling water heats up rapidly upon contact with the pipes, significantly reducing the cooling effect during the circulating spray process. Furthermore, the towers cannot coordinate air cooling of the pipes, reducing their heat dissipation efficiency, nor can they effectively refrigerate the cooling water, making it difficult to maintain a low temperature for extended periods. This limits the applicability of energy-saving and environmentally friendly cooling towers.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] In reality, the cooling medium in cooling towers is water. When water encounters high temperatures, it vaporizes, and the vaporized water is discharged by the fan. As a large amount of cooling water is lost due to vaporization, it needs to be replenished in time to ensure the cooling effect. The aforementioned comparative documents also show a large amount of cooling water loss, which requires continuous replenishment and reduces the energy-saving and environmental protection effect of the cooling tower. Therefore, there is an urgent need in this field to improve the cooling tower to overcome the shortcomings of the existing technology. Utility Model Content

[0016] In this invention, a condenser shroud that is narrow at the top and wide at the bottom is designed so that when the vaporized cooling water floats to the surface, it comes into contact with the condenser shroud and condenses.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-8 An energy-saving and environmentally friendly cooling tower includes a tower body 1. The tower body 1 has an exhaust device 2 at its upper end, connected to the interior of the tower body 1 and used for exhausting air. A heat transfer pipe 3, connected to the outside, is located in the middle of the tower body 1 for transporting the heat transfer medium to be cooled. Several spray pipes 4, located above the heat transfer pipes 3 and used for spraying the heat transfer pipes 3, are located on one side of the tower body 1 and connected to the bottom of the tower body 1 for transporting cooling water. A first delivery pipe 6, connected to the first delivery pump 5 and several spray pipes 4, is fixedly installed. A condenser hood 7, narrow at the top and wide at the bottom, is fixedly installed above the spray pipes 4 in the upper part of the tower body 1. A lower groove 8, adapted to its inner wall, is fixedly installed at the lower part of the condenser hood 7 and connected to the outside. Condensation equipment 9 is provided both inside and outside the tower body 1. A first return water pipe 10, connected to the lower groove 8, is fixedly installed between the condenser equipment 9 outside the tower body 1 and the condenser hood 7. The condenser equipment 9 outside the tower body 1 is connected to the interior of the tower body 1.

[0032] Specifically, the aforementioned exhaust device 2 is a known technology, such as a fan. When cooling of the heat medium is required, the exhaust device 2 is turned on to discharge the heat generated during cooling. The heat medium to be cooled is circulated through the end of the heat medium conveying pipe 3 extending to the outside. At the same time, the first conveying pump 5 is turned on. The first conveying pump 5 delivers cooling water, which has been cooled or circulated at the bottom of the tower body 1, through the first conveying pipe 6 to several spray pipes 4. The water is then sprayed downwards through the spray heads at the bottom of the spray pipes 4. The cooling water comes into contact with the outside of the heat medium conveying pipe 3 and cools the heat medium inside the heat medium conveying pipe 3 through heat exchange. At the same time, when the temperature of the heat medium is high, the cooling water will vaporize when it comes into contact with the heat medium conveying pipe 3. The vaporized cooling water rises. Since the condenser 7 is narrow at the top and wide at the bottom, a large amount of... The vaporized water will come into contact with the condenser 7. When the vaporized water comes into contact with the condenser 7, it will condense. After condensation, the vaporized water will be converted back into cooling water and slide down the inner wall of the condenser 7, finally landing in the lower groove 8. The cooling water in the lower groove 8 will flow back to the condenser 9 through the first return water pipe 10. The condenser 9 is a known technology. Its main function is to cool the recovered cooling water. The cooled water is then transported back into the tower body 1, realizing the recycling of the vaporized cooling water, reducing the amount of cooling water added, and achieving energy saving and environmental protection. It is worth noting that a cooling water adding pipe is also provided on the side of the tower body 1, which is not shown in the figure. It is mainly used to add cooling water appropriately according to the cooling water loss to ensure the overall cooling effect of the cooling tower.

[0033] As a technical optimization of this utility model, a second delivery pump 11 is provided on one side of the tower body 1 and communicates with its interior. An annular pipe 13 located on the upper side of the condenser hood 7 is fixedly installed inside the tower body 1. A second delivery pipe 12 is fixedly installed between the annular pipe 13 and the second delivery pump 11. Several water leakage holes 14 adapted to the condenser hood 7 are opened at the lower part of the annular pipe 13. A second return water pipe 15 adapted to the position of the condenser hood 7 is fixedly installed between the condensing equipment 9 and the side of the tower body 1.

[0034] Specifically, during the cooling process, the second delivery pump 11 is turned on. The second delivery pump 11 delivers the low-temperature cooling water in the tower body 1 to the position of the annular pipe 13 through the second delivery pipe 12, and drips onto the upper side of the condenser 7 through several water leakage holes 14 to cool the condenser 7 and improve the condensation effect of the condenser 7 on the vaporized cooling water. The cooling water in the upper part of the condenser 7 is collected and returned to the condensation equipment 9 through the second return water pipe 15. The condensation equipment 9 cools the heat-exchanged cooling water again and delivers it to the tower body 1.

[0035] As a technical optimization of this utility model, a filter plate 16 with several filter holes is fixedly installed inside the tower body 1. The filter plate 16 is located below the heat medium conveying pipe 3. A drive motor 17 is fixedly installed on one side of the tower body 1. A cleaning component 19 for cleaning the upper part of the filter plate 16 is provided on the upper part of the filter plate 16. A drive screw 18 with one end fixedly installed to the output end of the drive motor 17 is rotatably connected between the opposite side walls inside the tower body 1. The drive screw 18 passes through the upper part of the cleaning component 19 and is threadedly connected to it. A maintenance port 20 adapted to the position of the filter plate 16 is opened through one side of the tower body 1. A sealing plate 21 adapted to the maintenance port 20 is provided at the position of the maintenance port 20. An installation cover plate 22 for installing and fixing is fixedly installed on one side of the sealing plate 21. A sealing strip 23 is embedded between the installation cover plate 22 and the inner side wall of the maintenance port 20. The sealing strip 23 is elastic.

[0036] Specifically, cooling water is filtered through filter plate 16. Larger impurities (such as scale buildup on the outer surface of the heat transfer pipe 3) remain on the upper part of filter plate 16, ensuring the cleanliness of the cooling water at the bottom of the tower body 1. During the cooling process, the drive motor 17 can be turned on intermittently or at set times via programming. The output end of the drive motor 17 rotates reciprocally, which drives the drive screw 18 to rotate reciprocally. When the drive screw 18 rotates, it drives the cleaning component 19 to move back and forth on the upper part of the filter plate 16. The lower surface of the cleaning component 19 can be a brush, etc., which mainly serves to clean larger impurities on the filter plate 16. The impurities can be cleaned. When there are many impurities on the filter plate 16, the mounting cover 22, which is installed by bolts, is removed. The sealing plate 21 and the mounting cover 22 located in the maintenance port 20 are taken out. The filtered impurities remaining on the upper part of the filter plate 16 are removed with professional tools. Then the mounting cover 22 and the sealing plate 21 are reinstalled. During installation, the sealing strip 23 is embedded between the mounting cover 22 and the inner wall of the maintenance port 20 to ensure the sealing effect of the maintenance port 20, improve the cleanliness of the cooling water at the bottom of the tower body 1, and facilitate the maintenance and cleaning of the upper part of the filter plate 16.

[0037] As a technical optimization of this utility model, ventilation louvers 24 are fixedly installed on multiple sides of the tower body 1. The ventilation louvers 24 are mainly used to accelerate the heat dissipation effect of cooling water, and they can be selectively installed in actual applications.

They are mature technologies and have been fully disclosed, so they will not be repeated in the instruction manual. All of the electrical products mentioned above are equipped with power cords, and they are electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power cords.
