Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a novel anti-fogging cooling tower. Background Technology

[0002] During the operation of a cooling tower, cooling air comes into contact with wastewater or steam, absorbing waste heat and achieving cooling. However, this process generates some evaporated water vapor, which escapes into the environment, leading to water loss. Cooling towers are particularly prone to plume phenomena, exhibiting large amounts of water vapor, especially in low-temperature and high-humidity environments. This is particularly common in the central and eastern regions of China, where low winter temperatures and high humidity exacerbate the plume phenomenon, creating visual pollution. This plume not only affects the aesthetics of the surrounding environment but also negatively impacts the quality of life for nearby residents. Summary of the Invention

[0003] This disclosure provides a novel structure for eliminating fog in cooling towers, which at least solves the above-mentioned technical problems existing in the prior art.

[0004] According to a first aspect of this disclosure, a novel anti-fogging cooling tower is provided, including a base disposed on the ground; A main frame, which is mounted on a base and extends along a first direction; A stuffing box, which is mounted on the main frame; A flow diversion unit, which is installed on the main frame, is used to divert hot water into the packing tank; It also includes a defogging unit, which is installed on the main frame to perform defogging treatment inside the cooling tower.

[0005] Furthermore, the defogging unit includes, The ventilation duct is fixedly installed on the upper side of the main frame and is located on the upper side of the packing box; A demister, which is installed inside the air duct to eliminate fog inside the air duct; A fan is installed inside the air duct and is located above the demister to blow water mist from the packing box into the air duct.

[0018] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0019] During the operation of a cooling tower, cooling air comes into contact with wastewater or steam, thereby absorbing waste heat and achieving cooling. However, this process generates some evaporated water vapor, which escapes into the environment through the air, leading to water loss. Especially under conditions of low ambient temperature and high humidity, cooling towers are more prone to plume phenomena, exhibiting a large amount of water vapor mist.

[0020] Please see Figure 1 , Figure 2 and Figure 3 To address the aforementioned problems, this embodiment provides a novel anti-fogging cooling tower, comprising a base 1 disposed on the ground; a main frame 3 disposed on the base 1, the main frame 3 extending along a first direction, and the main frame 3 including baffles 4 disposed on its periphery; wherein the first direction is the height direction.

[0021] The packing box 7 is mounted on the main frame 3; the packing box 7 includes a packing layer and an air layer; a flow guiding unit is mounted on the main frame 3 to guide hot water into the packing box 7; and a demisting unit is mounted on the main frame 3 to perform demisting treatment inside the cooling tower.

[0022] The main frame 3 extends along the first direction, providing not only a robust support structure for the entire cooling tower but also space for the installation and operation of other components such as the stuffing box 7 and the air diversion unit. The material filled inside the stuffing box 7 helps improve cooling efficiency by increasing the contact area between water and air, achieving more efficient heat exchange. The air diversion unit is designed to guide hot water into the stuffing box 7, ensuring uniform water flow and promoting the heat exchange process. The demisting unit plays a crucial role in demisting, removing water mist from the cooling tower through physical or chemical methods, improving the cooling tower's efficiency and environmental friendliness. The overall working principle is as follows: hot water is transported to the stuffing box 7 through the air diversion unit, where it fully contacts the air for heat exchange, transferring heat to the air and lowering the hot water temperature. Subsequently, the dispersed water mist is effectively removed by the demisting unit, thus achieving efficient cooling and maintaining clean surrounding air.

[0023] There are generally two main anti-fogging technologies currently available. One is to install a regulating vent and an anti-fogging module on the water collector. When obvious "white smoke" appears at the cooling tower outlet, the regulating vent is opened to introduce dry air to mix with the humid air inside the tower, thus achieving the effect of anti-fogging. The second method uses finned tubes: an air inlet window is arranged on the upper part of the water collector, and finned tubes are arranged at the inlet of the air window. Hot water is introduced into the finned tubes. When fog removal is required, the air inlet window is opened to heat the air entering the tower with the hot water from the finned tubes, and mixes with the saturated humid and hot air inside the tower to reduce the humidity of the air exiting the tower, thereby achieving the purpose of fog removal.

[0024] However, both of these technologies require increasing the height of the cooling tower, which directly leads to larger profiles and increased material usage, thus increasing operating costs.

[0025] Please see Figure 2 and Figure 3 To address the aforementioned technical issues, the demisting unit includes a duct 12, which is fixedly installed on the upper side of the main frame 3, that is, fixedly installed on the upper surface of the main frame 3. At the same time, the duct 12 is also connected to the interior of the main frame 3, and the duct 12 is located on the upper side of the packing box 7. Demister 11, which is installed inside the air duct 12 to eliminate fog inside the air duct 12; A fan 13 is installed inside the air duct 12, above the demister 11, to blow water mist from the packing box 7 into the air duct 12. A hygrometer is installed inside the air duct 12 to detect the humidity level.

[0026] The duct 12 serves as a flow channel for airflow. It is fixedly installed on the upper side of the main frame 3, above the stuffing box 7, ensuring smooth airflow from the stuffing box 7 to the outside. Moisture and water mist inside the stuffing box 7 are carried into the duct 12 by the airflow. The demister 11 is located inside the duct 12, and its function is to remove mist from the duct 12, improving the cleanliness of the exhaust gas. The fan 13 is also installed inside the duct 12, above the demister 11. It uses a strong airflow to blow water mist from the stuffing box 7 on the main frame 3 into the duct 12, allowing the airflow in the duct 12 to carry more moisture, thereby improving the working efficiency of the demister 11.

[0027] Please see Figure 2 and Figure 3 A water collector 9 is installed on the top of the stuffing box 7, and a mixing and regulating air window 10 is installed on the top of the water collector 9. The water collector 9, installed on the top of the stuffing box 7, mainly collects water droplets generated during the defogging process. The mixing and regulating air window 10, located on top of the water collector 9, regulates and mixes the air entering the stuffing box 7. It can adjust the air volume and direction according to the actual situation. By adjusting different air intake volumes and intake speeds, the fog generated by the stuffing process can be effectively eliminated, while ensuring uniform gas flow within the stuffing box 7 and maintaining a suitable working environment.

[0028] Please see Figure 2 and Figure 3 To further improve the defogging capability, a water collection basin 2 is also included. The water collection basin 2 is mounted on the base 1 and located below the packing box 7. An air inlet louver 17 is provided at the top of the water collection basin 2 and is mounted on the outer wall of the main frame 3.

[0029] The water collection basin 2 is located on the base 1, below the stuffing box 7. Its main function is to collect the atomized water and uncondensed water droplets discharged from the bottom of the stuffing box 7, thereby reducing water waste and improving the overall defogging efficiency. The air inlet louver 17 is located at the top of the water collection basin 2 and is embedded in the outer wall of the main frame 3. By adjusting the airflow speed and direction, it promotes the evaporation and discharge of water vapor in the stuffing box 7, further improving the defogging effect.

[0030] Please see Figure 2 and Figure 3 To facilitate the treatment of the cold water collected in the water collection basin 2, an overflow pipe 18 is provided on one side of the water collection basin 2, and a float ball 14 is provided on the overflow pipe 18, with the float ball 14 located inside the water collection basin 2.

[0031] The float 14 monitors the water level in the collection basin 2. Once the water level exceeds a preset height, the float 14 rises with the water level, triggering the overflow pipe 18 to open, thereby draining excess cold water from the collection basin 2 and preventing it from overflowing. The overflow pipe 18 provides a water outlet when the water level in the collection basin 2 is too high, ensuring the water level remains within a safe range. In this way, the collection basin 2 can effectively collect and treat excess cold water, preventing overflow and maintaining the normal operation of the system.

[0032] Meanwhile, a water outlet pipe 21 is fixedly connected to one side of the outer wall of the water collection basin 2, and a circulating water pump 16 is fixedly connected to one end of the water outlet pipe 21. A drain valve 20 is fixedly connected to one side of the outer wall of the water collection basin 2. This allows for the active discharge of water from the water collection basin 2.

[0033] Please see Figure 2 and Figure 3 A temperature detector 15 is installed on one outer wall of the water collection basin 2, and an electric control box is installed on the water collection basin 2. The electric control box is electrically connected to the fan 13 and the temperature detector 15. The temperature detector 15 is a PT100 model.

[0034] Specifically, during use, hot water enters the packing layer and air layer in the packing box 7 through the diversion unit; the temperature detector 15 monitors the water temperature after cooling and feeds the water temperature value back to the PLC in the electrical control box 19 to automatically control the switch of the diversion unit. When the humidity at the outlet of the fan 13 is close to 100%, the mixing and regulating vent 10 is opened and its opening is controlled by humidity. At the same time, the air volume of the fan 13 is adjusted by the frequency converter. When the humidity is adjusted to be below 95% or there is no "white smoke", the opening of the mixing and regulating vent 10 and the operating frequency of the fan 13 are fixed to achieve a highly efficient defogging effect.

[0035] Please see Figure 2 , Figure 3 and Figure 4 The diversion unit includes a water distribution pipe 22, which is located on the upper or lower side of the packing box 7. In this embodiment, the water distribution pipe 22 is located on the upper and lower sides of the packing box 7. A water inlet pipe 6 is provided at the connection of the two water distribution pipes 22 to deliver hot water to the two water distribution pipes 22; a nozzle 8, which is installed on the water distribution pipe 22 to deliver the hot water in the water distribution pipe 22 to the packing box 7; and an electric regulating valve 5, which is installed on the water distribution pipe 22 to control the amount of hot water entering the water distribution pipe 22. The electric regulating valve 5 is electrically connected to the control box.

[0036] The function of the water distribution pipe 22 is to transport hot water to the stuffing box 7. It is located on the upper or lower side of the stuffing box 7, ensuring precise delivery of hot water to the designated location. The nozzle 8 is installed on the water distribution pipe 22, evenly spraying the hot water from the pipe into the stuffing box 7, thus ensuring uniform water dispersion. The electric regulating valve 5 is located on the water distribution pipe 22 and controls the flow rate of hot water entering the pipe. It is connected to the control box via an electrical signal for automated regulation.
