Description

Technical Field

[0001] This utility model relates to the field of circulating water treatment devices, specifically to an anti-fogging, water-saving, and heat exchange structure. Background Technology

[0002] With increasingly stringent environmental protection requirements, the water-saving and defogging capabilities of industrial cooling towers have become an important indicator for evaluating their quality. However, the packing heat exchange structures currently used in cooling towers do not possess water-saving and defogging capabilities or have low capabilities, which is not conducive to reducing dripping losses and suppressing the formation of white mist, causing significant problems for users' daily use and environmental protection. Therefore, a cross-flow defogging and water-saving heat exchange structure suitable for cooling tower applications is proposed. Utility Model Content

[0003] In view of the problems existing in the background art, the purpose of this utility model is to provide an anti-fogging and water-saving heat exchange structure, which effectively solves the problems existing in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A defogging and water-saving heat exchange structure includes a water distribution layer, a module body, and air-guiding and water-collecting layers disposed on the left and right sides of the module body. The module body includes a flow guide block and a cooling block. The flow guide block is located between the water distribution layer and the cooling block. Multiple parallel first channels are correspondingly arranged in the flow guide block and the cooling block. A second channel is arranged between adjacent first channels. The first and second channels are open on all four sides. A cover plate is provided at the upper opening of the first channel. The water distribution layer includes multiple first spray water pools longitudinally disposed above the cover plate and second spray water pools disposed between adjacent first spray water pools. The first and second spray water pools are respectively connected to water pipes with valves. Multiple channels with openings on both the left and right sides are evenly distributed in the air-guiding and water-collecting layers. The channels are higher on the outside and lower on the inside.

[0006] Furthermore, the flow guide block and the cooling block each include a plurality of parallel packing plates, with adjacent packing plates forming the first channel or the second channel.

[0007] This utility model has the following beneficial technical effects:

[0008] This utility model achieves water-saving and fog-eliminating effects in cooling towers through the cooperation of the water distribution layer and the main module. Compared with existing water-saving and fog-eliminating methods for cooling towers, this application has a simple structure, low cost, and stable operation, making it suitable for widespread use.

[0012] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0013] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," and "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0014] like Figure 1-3 As shown, the anti-fogging and water-saving heat exchange structure described in this embodiment includes a water distribution layer, a module body, and air-guiding and water-collecting layers 1 arranged on the left and right sides of the module body. The module body includes a flow guide block 2 and a cooling block 3. The flow guide block 2 is located between the water distribution layer and the cooling block 3. Multiple parallel first channels 4 are arranged in the flow guide block 2 and the cooling block 3. A second channel 5 is arranged between adjacent first channels 4. The first channel 4 and the second channel 5 are open around their perimeters. A cover plate 6 is provided at the upper opening of the first channel 4 to initially close the upper opening of the first channel 4.

[0015] The longitudinal arrangement of the water distribution layer includes multiple second spray pools 7 correspondingly set above the cover plate and a first spray pool 8 set between adjacent second spray pools 7. The water outlet in the second spray pool 7 can enter all channels, while the water outlet in the first spray pool 8 is blocked by the cover plate 6 and will not enter the first channel 4. The spray pools 7 and 8 are respectively connected to water pipes with valves for transporting circulating water to be cooled. The spray pools 7 and 8 can be activated separately.

[0016] The air guide and water collection layer 1 has multiple channels 9 that are open on both the left and right sides. The channel 9 has a hexagonal cross-section and is higher on the outside and lower on the inside. This allows airflow to pass through the first channel 4 and the second channel 5 in the left and right directions, while also effectively preventing liquid droplets from splashing out and reducing the water content of the gas reaching the air outlet of the cooling tower.

[0017] The flow guide block 2 and the cooling block 3 each include several parallel packing plates 10. Adjacent packing plates 10 form a first channel 4 or a second channel 5. The surface specifications of the packing plates in the flow guide block 2 are different from those in the cooling block 3. The main function of the flow guide block 2 is to better disperse the water flow to the cooling block 3. The function of the cooling block 3 is to achieve efficient heat exchange between air and water. Preferably, the flow guide block 2 uses a staggered wave structure packing plate, and the cooling block 3 uses a dot wave structure packing plate. Alternatively, three packing plates 10 can be grouped together as a first channel 4. The first channel 4 is a three-plate, two-cavity form, with the cover plate 6 closing the upper openings of the two cavities. The second channel 5 is still a two-plate, single-cavity form. This expands the flow channel of the first channel 4. In practical applications, the appropriate method can be selected as needed.

[0018] The working principle of this embodiment is as follows:

[0019] Under the action of the induced draft fan, outside air passes through the first channel 4 and the second channel 5 in the left and right directions. When the second spray water tank 8 discharges water and the first spray water tank 7 does not discharge water, there is water in the second channel 5 and no water in the first channel 4. The air in the second channel 5 comes into contact with the spray water flow and exchanges heat to generate saturated humid and hot air. The air entering the first channel 4 exchanges heat with the water flow and air in the adjacent second channel 5 through the packing plate 10, and the temperature rises to form dry and hot air. After the saturated humid and hot air in the second channel 5 and the dry and hot air in the first channel 4 are mixed, they tend to remain in an unsaturated state, which fundamentally inhibits the generation of white mist in the cooling tower and is beneficial to environmental protection. In addition, since the moisture content of the air exiting the tower is reduced, the dripping loss and sewage discharge of the cooling tower are also effectively reduced.

[0020] When the cooling tower has a large heat load, water is discharged from the first spray water tank 7, and spray water flows down in both the first channel 4 and the second channel 5. At this time, all the air comes into contact with the water flow for heat exchange. The heat transfer efficiency of wet cooling is relatively high, which is conducive to the completion of the cooling tower's heat load. The independent switch settings of the first spray water tank 7 and the second spray water tank 8 allow users to easily switch the cooling tower mode according to actual usage needs, which is beneficial to users.

[0021] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
