Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a water collector and a cooling tower. Background Technology

[0002] Conventional wet cooling towers work by spraying hot water onto the surface of the packing material, which then comes into contact with cold air passing upward through the packing. At this time, heat exchange occurs between the hot water and the cold air, and some of the hot water is evaporated. That is, the latent heat of vaporization in the evaporated water vapor is released into the air. Finally, the cooled water falls into a water pool at the bottom of the tower.

[0003] As air rises through the packing material, it exchanges heat with the sprayed water. When the air leaves the packing material, it carries a significant amount of moisture. Part of this moisture is water vapor mixed with the evaporated sprayed water, and the other part consists of small water droplets formed from the sprayed water being splashed. The former cannot be easily separated from the air using mechanical methods, but the latter can be separated from the air using a water collector, allowing the water droplets to be recovered. In the industry, the water loss caused by these tiny water droplets carried away by the air is called drift loss. Therefore, the effectiveness of the water collector directly determines the amount of drift loss in the cooling tower.

[0004] The structure of most currently used water collectors can be found in Chinese patent document CN218673215U (Patent Title: A Water Collector and Cooling Tower). Its water collection principle is that as air carrying water droplets passes through the channels between the collector plates from bottom to top, the airflow direction changes within the channels. Larger water droplets, due to their larger droplet diameter, mass, and inertia, are intercepted by the collector plates, thus separating from the airflow and eventually falling into the water pool at the bottom of the tower, thereby reducing water drift loss in the cooling tower. However, smaller water droplets in the rising airflow pass upwards along with the airflow through the airflow channels of the water collector, resulting in poor interception of these droplets. Therefore, the inventors need to improve the structure of the water collector to overcome this problem. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned defects in the prior art, it is necessary to provide a water collector with good water droplet separation effect;

[0006] It is also necessary to provide a cooling tower equipped with this water collector.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a water collector, comprising at least two layers of water collection layers stacked vertically, wherein the upper and lower water collection layers respectively form an upper water collection layer and a lower water collection layer, the upper water collection layer comprising a plurality of horizontally spaced upper water collection plates, the lower water collection layer comprising a plurality of horizontally spaced lower water collection plates, the upper and lower water collection plates being staggered and both having a downwardly curved arc structure, the area enclosed between the upper water collection plate and two adjacent lower water collection plates forming an interception cavity, the gap between two adjacent upper water collection plates forming an air outlet channel, the gap between two adjacent lower water collection plates forming an air inlet channel, and the interception cavity communicating with both the air inlet channel and the air outlet channel.

[0008] Furthermore, the orthographic projection area of ​​the upper water collecting plate on the horizontal plane γ from top to bottom is region z1, and the gap between the orthographic projections of two adjacent lower water collecting plates on the horizontal plane γ from top to bottom is region z2, and region z2 completely falls into z1.

[0009] Furthermore, the central longitudinal plane of the air intake channel is y, and the upper water collection plate is symmetrically arranged about the central longitudinal plane y of the air intake channel.

[0010] Furthermore, the central longitudinal plane of the air outlet channel is x, and the lower water collection plate is symmetrically arranged about the central longitudinal plane x of the air outlet channel.

[0011] Furthermore, the width of the air intake channel is W1, and the width of the air outlet channel is W2, where W1 = W2.

[0012] Furthermore, the upper and lower water-collecting sheets are made of PP, PVC, or ABS.

[0014] Furthermore, the cooling tower also includes a tower body and packing material installed inside the tower body, and the water collector is fixedly installed inside the tower body and located above the packing material.

[0015] The beneficial effects of this utility model are as follows: In the water collector or cooling tower of this utility model, the airflow carrying water droplets flows from bottom to top through the water collector. Specifically, the airflow passes upward through the air inlet channel through the lower water collection layer and enters the interception chamber. At this time, the airflow will be directly blocked by the top wall of the interception chamber, and the water droplets in the airflow will fully contact the top wall of the interception chamber and adhere to the lower surface of the upper water collection plate, effectively intercepting large and small water droplets, and the water droplet separation effect is outstanding.

[0020] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Please see Figures 1-2 This utility model provides a water collector, including at least two water collection layers stacked one above the other. In two adjacent water collection layers, the upper water collection layer forms an upper water collection layer 10, and the lower water collection layer forms a lower water collection layer 20. The upper water collection layer 10 includes a plurality of upper water collection plates 11 arranged horizontally at intervals, and the lower water collection layer 20 includes a plurality of lower water collection plates 21 arranged horizontally at intervals. The upper water collection plates 11 and the lower water collection plates 21 are staggered and both have a downwardly curved arc structure. The area enclosed between the upper water collection plate 11 and the two adjacent lower water collection plates 21 forms an interception cavity 110. The gap between two adjacent upper water collection plates 11 forms an air outlet channel 111, and the gap between two adjacent lower water collection plates 21 forms an air inlet channel 211. The interception cavity 110 is connected to both the air inlet channel 211 and the air outlet channel 111.

[0022] In operation, the water collector of this invention allows airflow carrying water droplets to flow from bottom to top through the collector. Specifically, the airflow enters the interception chamber 110 through the lower water-collecting layer 20 from the air inlet channel 211. At this point, the airflow is directly blocked by the top wall of the interception chamber 110 (i.e., the lower surface of the upper water-collecting plate 11). The water droplets in the airflow then come into full contact with the top wall of the interception chamber 110 and adhere to the lower surface of the upper water-collecting plate 11, effectively intercepting both large and small water droplets, resulting in excellent water droplet separation. In addition, the downward-curved arc structure of the upper water-collecting plate 11 facilitates the flow of airflow in the interception chamber 110 to both sides, ultimately flowing out through the air outlet channel 111, ensuring that the airflow passes smoothly through the water collector. Furthermore, in the upward-flowing airflow, in addition to a portion of the airflow entering the interception chamber 110 through the air intake channel 211, a portion of the airflow will flow directly upward to the lower water-collecting plate 21. At this time, the lower surface of the lower water-collecting plate 21 can also directly intercept the water droplets in the airflow, thereby improving the separation efficiency of the water droplets in the airflow.

[0023] In addition, the rising airflow passes through the intake channel 211 and enters the interception chamber 110, and then flows out from the outlet channel 111 through the interception chamber 110. During this process, there is a significant difference between the size of the airflow channel and the size of the space on both sides of the channel. During the flow of the airflow, due to friction, some of the sound energy is converted into heat energy and thus consumed, thereby reducing the sound of the airflow and achieving good noise reduction effect.

[0024] In this embodiment, the orthographic projection area of ​​the upper water-collecting plate 11 onto the horizontal plane γ from top to bottom is region z1, and the gap between the orthographic projections of two adjacent lower water-collecting plates 21 onto the horizontal plane γ from top to bottom is region z2, wherein region z2 completely falls within region z1. Therefore, when the rising airflow passes through the air intake channel 211 and the lower water-collecting layer 20, the upper water-collecting plate 11 can effectively intercept the airflow, ensuring the water interception effect.

[0025] In a preferred embodiment, the central longitudinal plane of the air intake channel 211 is y, and the upper water collection plate 11 is symmetrically arranged about the central longitudinal plane y of the air intake channel 211. Additionally, the central longitudinal plane of the air outlet channel 111 is x, and the lower water collection plate 21 is symmetrically arranged about the central longitudinal plane x of the air outlet channel 111, to improve aesthetics and ensure good visual consistency.

[0026] In this embodiment, the width of the air intake channel 211 is W1, and the width of the air outlet channel 111 is W2, wherein W1 = W2.

[0027] The upper water collection plate 11 and the lower water collection plate 21 can be made of PP (polypropylene), PVC (polyvinyl chloride), or ABS (acrylonitrile-butadiene-styrene copolymer). PP has high-temperature resistance and is suitable for high-temperature industrial cooling towers; PVC has good weather resistance and is suitable for hot and humid climates; while ABS has high strength and impact resistance. Users can choose according to their needs; no specific limitation is made here.

[0028] This utility model also provides a cooling tower, which includes the aforementioned water collector, a tower body, and packing material installed inside the tower body. The aforementioned water collector is fixedly installed inside the tower body and located above the packing material. Specifically, during installation, the two ends of the upper water collector 11 and the two ends of the lower water collector 21 can be fixedly connected to the inner walls of the opposite sides of the tower body, thereby achieving a fixed connection between the water collector and the tower body. In use, the rising airflow passes through the packing material and then upwards through the water collector, which traps water droplets in the airflow to achieve water vapor separation.

[0029] The cooling tower of this utility model has all the technical features of the aforementioned water collector, and therefore has the same technical effect as the aforementioned water collector.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
