Description

Technical Field

[0001] This application relates to the field of cooling tower technology, and in particular to a thin-film suspended packing for cooling towers. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. Its cooling effect is achieved by the heat exchange between water and air flow to generate steam. The steam evaporates and carries away the heat, thus achieving heat dissipation through evaporation, convection, and radiation. This process dissipates waste heat generated in industrial processes or refrigeration and air conditioning systems to lower the water temperature and ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.

[0003] When using cooling towers, packing material is needed to increase the contact area between air and water, thereby increasing the cooling efficiency of the water. However, when using ordinary cooling tower film-suspended packing material, the air duct will be blocked due to the packing material adhering to the surface. On the other hand, when using wavy cooling tower film-suspended packing material that leaves the air duct open, the cooling efficiency of the air is reduced due to the larger air duct. Therefore, we have proposed a new type of cooling tower film-suspended packing material. Utility Model Content

[0004] This application provides a thin-film suspended packing for cooling towers to solve the problems mentioned above.

[0005] This application provides a thin-film suspended packing for cooling towers, comprising:

[0006] The cooling tower water supply main pipe has a first packing layer and a second packing layer interlaced around its outer side;

[0007] Both the first and second filler layers are wavy, with the first filler layer being a left-sloping wave and the second filler layer being a right-sloping wave.

[0008] The first and second filler layers are both fixedly connected at equal intervals to the corrugated grooves of the first and second filler layers. Ventilation holes are opened through the middle of the first and second filler layers and on both sides of the second filler layer.

[0009] Preferably, a cooling cavity exists between the first absorbent cotton plate and the second absorbent cotton plate.

[0010] Preferably, the first filler layer and the second filler layer are pressed together.

[0024] Various embodiments of this application may exist in the form of a range. It should be understood that the description in the form of a range is merely for convenience and brevity and should not be construed as a rigid limitation on the scope of this application. Therefore, it should be considered that the range description has specifically disclosed all possible sub-ranges and single numerical values ​​within that range. For example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges, such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and single numbers within the range, such as 1, 2, 3, 4, 5, and 6, regardless of the range. In addition, whenever a numerical range is indicated in this application, it means including any referenced number (fraction or integer) within the indicated range. Unless otherwise specified, all raw materials, reagents, instruments, and equipment used in this application can be purchased commercially or prepared using existing equipment.

[0025] In this application, unless otherwise stated, directional terms such as "upper" and "lower" specifically refer to the drawing directions in the accompanying drawings. Furthermore, in this application, the terms "comprising," "including," etc., mean "including but not limited to." In this application, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In this application, "and / or" describes the relationship between related objects, indicating that three relationships may exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. A and B can be singular or plural. In this application, "at least one" means one or more, and "more than one" means two or more. "At least one," "at least one of the following," or similar expressions refer to any combination of these items, including any combination of a single item or a plural item. For example, "at least one of a, b, or c", or "at least one of a, b, and c", can both mean: a, b, c, ab, i.e., a and b, ac, bc, or abc, where a, b, and c can be a single or multiple.

[0026] like Figures 1-4 As shown in the figure, this application provides a cooling tower film suspension packing, comprising:

[0027] The cooling tower water supply main pipe 1 has a first packing layer 2 and a second packing layer 3 interlaced around its outer side;

[0028] Both the first filler layer 2 and the second filler layer 3 are wavy, with the first filler layer 2 being a left-sloping wave and the second filler layer 3 being a right-sloping wave.

[0029] The first absorbent cotton plate 6 and the second absorbent cotton plate 7 are fixedly connected at equal intervals in the corrugated groove 5 of the first filler layer 2 and the second filler layer 3. Ventilation holes 8 are opened through the middle of the first absorbent cotton plate 6 and the two sides of the second absorbent cotton plate 7.

[0030] like Figure 3 and Figure 4 As shown, there is a cooling cavity 4 between the first absorbent cotton plate 6 and the second absorbent cotton plate 7.

[0031] Specifically: air can enter the interior of cooling cavity 4.

[0032] like Figure 1 As shown, the first filler layer 2 and the second filler layer 3 are pressed together.

[0033] Specifically: the first packing layer 2 and the second packing layer 3 adopt packing layers that are already available on the market.

[0034] like Figure 3 and Figure 4 As shown, the first absorbent cotton plate 6 and the second absorbent cotton plate 7 are alternately arranged inside the corrugated groove 5.

[0035] Specifically: A first absorbent cotton plate 6 and a second absorbent cotton plate 7 are installed inside the wave groove 5. The first absorbent cotton plate 6 and the second absorbent cotton plate 7 have the same shape.

[0036] like Figure 1 and Figure 2 As shown, the corrugated ribs of the first filler layer 2 and the corrugated ribs of the second filler layer 3 are arranged intersectingly.

[0037] Specifically: the wavy ridges are arranged in a cross pattern so that the first filler layer 2 and the second filler layer 3 are not tightly fitted together, thus leaving an air duct.

[0038] like Figure 3 and Figure 4 As shown, both the first absorbent cotton plate 6 and the second absorbent cotton plate 7 are semi-circular.

[0039] Specifically: the arc shape of the first absorbent cotton plate 6 and the second absorbent cotton plate 7 is the same as the shape of the corrugated groove 5.

[0040] Principle: When the equipment is in use, the first packing layer 2 and the second packing layer 3 are attached together and then wrapped around the outside of the cooling tower water supply main pipe 1, and multiple layers are wrapped. In this way, the shape of the first packing layer 2 and the second packing layer 3 will not be affected by the wrapping, and there will be an air duct between the first packing layer 2 and the second packing layer 3.

[0041] Furthermore, each cooling cavity 4 also serves as an air passage. When the first packing layer 2 and the second packing layer 3 are in use, the cooling tower water supply main 1 is set vertically, and the first packing layer 2 and the second packing layer 3 are set vertically along with the cooling tower water supply main 1. Water flows downward from the upper end of the first packing layer 2 and the second packing layer 3, and air blows upward from between the first packing layer 2 and the second packing layer 3. The air and the flowing water come into full contact, thereby cooling the liquid. In addition, the ventilation holes 8 opened on the first absorbent cotton plate 6 and the second absorbent cotton plate 7 can increase the residence time of the air, thereby enabling the liquid to dissipate heat fully.

[0042] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed in this application.
