AI Technical Summary
The existing cooling tower mist removal treatment reduces water mist emissions by installing a single mist eliminator, but the mist removal efficiency is limited, and there may still be problems of water mist discharge outward.
A cooling tower water-saving and mist removal device is designed, using a combination of a spiral air outlet frame and a mist removal device. The spiral air outlet frame increases the movement distance and residence time of the water vapor through the spiral structure and mist arrangement of air outlet holes, while the mist removal device reduces water mist emission by changing the water vapor flow direction or absorbing water mist.
By increasing the movement distance and residence time of water vapor, a large amount of water mist is eliminated. At the same time, the water vapor is liquefied and flows back into the tower body, achieving a water-saving effect. The inclined structure on the top of the tower accelerates the fog removal speed, and the mist disinfection device further reduces water mist emissions.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of cooling towers, in particular to a water-saving and fog-eliminating device for cooling towers. Background Art
[0002] A cooling tower is a device used to cool water or other fluids. By the principle of evaporative cooling, it reduces the temperature of the circulating water, thereby providing a cooling effect for the system. During the operation of the cooling tower, water mist will be generated. The water mist may cause the surrounding environment to be humid, increasing the risk of icing, and may carry chemical substances and microorganisms in the cooling tower, posing a potential threat to the environment and human health. The existing fog-eliminating treatment for cooling towers directly installs a fog eliminator to reduce the emission of water mist, but the fog-eliminating efficiency of a single fog eliminator is limited, and there may still be a situation where water mist is emitted outward.
[0003] In view of the above problems, a water-saving and fog-eliminating device for cooling towers is now developed. Summary of the Utility Model
[0004] In order to overcome the shortcomings that the existing fog-eliminating treatment for cooling towers directly installs a fog eliminator to reduce the emission of water mist, but the fog-eliminating efficiency of a single fog eliminator is limited, and there may still be a situation where water mist is emitted outward, the utility model provides a water-saving and fog-eliminating device for cooling towers.
[0005] The technical implementation scheme of the utility model is as follows: A water-saving and fog-eliminating device for cooling towers includes a tower body, on which a tower top is installed, on which an installation chimney is installed. A mounting plate is connected to the lower part inside the installation chimney, on which a fan is installed. A connecting plate is placed in the lower part of the installation chimney, which is located above the fan. A spiral air outlet frame is connected to the connecting plate. The spiral air outlet frame includes a mounting column and a spiral air outlet plate. The mounting column is connected to the connecting plate, and the spiral air outlet plate is connected to the mounting column. A plurality of air outlet holes are formed in the spiral air outlet plate. A fog eliminator is clamped on the mounting column, and the fog eliminator is connected to the upper part of the installation chimney.
[0006] Furthermore, the tower top is of an inclined surface structure.
[0007] Furthermore, a limiting block is provided at the lower part of the installation chimney.
[0008] Furthermore, a rubber block is provided on the mounting column.
[0009] Furthermore, the air outlet holes are arranged in a staggered manner.
[0010] Furthermore, the fog eliminator is of a detachable connection structure.
[0011] By adopting the above technical scheme, the beneficial effects of the utility model are as follows:
[0012] The utility model eliminates a large amount of water mist by setting a spiral air outlet frame. As the water vapor moves upward to the spiral air outlet frame, the spiral structure of the spiral air outlet plate and the staggered arrangement of the air outlet holes can increase the movement distance of the water vapor and extend the residence time of the water vapor, thereby eliminating a large amount of water mist. At the same time, after the water vapor liquefies, it can flow back downward into the tower body along the spiral air outlet plate, thus achieving the effect of water conservation. The inclined surface structure of the tower top can reflux the water vapor liquefied by cooling into the tower body for reuse, and can also quickly gather the remaining water vapor into the installation chimney, thereby accelerating the fog elimination speed.

[0018] Referring to the embodiments herein means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0019] A cooling tower water-saving and fog-eliminating device, as Figures 1 - 4 shown, includes a tower body 2, a tower top 1 is installed on the tower body 2, the tower top 1 is of an inclined surface structure, an installation chimney 3 is installed on the tower top 1, a limiting block is provided at the lower part of the installation chimney 3, an installation plate 4 is connected to the lower part inside the installation chimney 3, a fan 5 is installed on the installation plate 4, a connecting plate 6 is placed at the lower part of the installation chimney 3, the connecting plate 6 is located above the fan 5, a spiral air outlet frame 7 is connected to the connecting plate 6, the spiral air outlet frame 7 includes an installation column and a spiral air outlet plate, an installation column is connected to the connecting plate 6, a rubber block is provided on the installation column, a spiral air outlet plate is connected to the installation column, a plurality of air outlet holes 8 are formed in the spiral air outlet plate, the air outlet holes 8 are all arranged in a staggered manner, a fog eliminator 9 is clamped on the installation column, the fog eliminator 9 is connected to the upper part of the installation chimney 3, and the fog eliminator 9 is of a detachable connection structure.
[0020] It should be noted that a cooling tower is a device used to cool water or other fluids. By the principle of evaporative cooling, it reduces the temperature of the circulating water, thereby providing a cooling effect for the system. During the operation of the cooling tower, water mist is generated. The water mist may cause the surrounding environment to be humid, increasing the risk of icing, and may carry chemical substances and microorganisms in the cooling tower, posing a potential threat to the environment and human health. During the operation of the cooling tower, water vapor is generated inside the tower body 2. The water vapor moves upward. When the water vapor contacts the tower top 1, part of the water vapor is liquefied by the cold and flows back into the tower body 2 along the inclined surface of the tower top 1, facilitating the reuse of the water vapor. The inclined surface structure of the tower top 1 can also quickly gather the remaining water vapor into the installation chimney 3. The fan 5 can continue to cool and liquefy the water vapor while transporting the water vapor to the spiral air outlet frame 7. The spiral structure of the spiral air outlet plate and the staggered arrangement of the air outlet holes 8 can increase the movement distance of the water vapor and extend the residence time of the water vapor, thereby eliminating a large amount of water mist. At the same time, after the water vapor is liquefied, it can flow downward along the spiral air outlet plate back into the tower body 2, thus achieving the effect of water conservation. After the water mist elimination treatment by the spiral air outlet frame 7, there is still a small amount of water mist moving upward. The demister 9 can change the flow direction of the water vapor or absorb the water mist through special materials, thereby reducing the water mist emission. The installation methods of the connecting plate 6, the spiral air outlet frame 7, and the demister 9 make disassembly and replacement more convenient.
[0021] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present utility model.
