Description

Technical Field

[0001] This utility model relates to the technical field of cooling tower cooling equipment, and in particular to a PVC sheet cooling tower packing material with an improved corrugated structure. Background Technology

[0002] As the core equipment of industrial cooling systems, the working efficiency of cooling towers mainly depends on the heat exchange performance of the packing. As a key component in cooling towers that promotes the contact between gas and liquid phases, the structural design of the packing directly affects the cooling efficiency, water flow distribution uniformity, and equipment resistance. PVC (polyvinyl chloride) sheets have become one of the mainstream materials for cooling tower packing due to their advantages such as corrosion resistance, low cost, and good processing performance.

[0003] Traditional PVC sheets have a smooth surface, and some scale can remain on the surface during heat exchange. Scale particles easily adhere and form hard scale, which is especially prominent when the hardness of the circulating water is high. Scale buildup on the sheet surface affects the flow of water and air, reducing cooling efficiency. Traditional corrugated structures often use unidirectional guide plates to guide the liquid and air for heat exchange, but the unidirectional guide plate has limited flow guiding capacity. Water flow is prone to deviation or "channeling" phenomena in the packing layer (i.e., water flow is concentrated in a local area), resulting in reduced packing utilization. Therefore, the above problems need to be addressed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling tower packing PVC sheet with an improved corrugated structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a PVC sheet for cooling tower packing with an improved corrugated structure, comprising stacked cooling plates, wherein multiple film strips are alternately installed on the top and bottom surfaces of the cooling plates, and the film strips are equipped with a guiding mechanism and an assembly mechanism to facilitate the stacking of the cooling plates.

[0006] Preferably, the coating strip is S-shaped and the cross-section of the coating strip is trapezoidal.

[0007] Preferably, the guiding mechanism includes a plurality of first guide plates that are equidistantly and obliquely mounted on the coating strip and a second guide plate that is mounted at the turning point of the coating strip.

[0008] Preferably, both the first guide plate and the second guide plate are trapezoidal.

[0009] Preferably, both the cooling plate and the coating strip are coated with a foaming layer.

[0010] Preferably, the assembly mechanism includes a retaining bead fixed to the second guide plate and a retaining groove formed on the second guide plate, wherein the retaining bead and the retaining groove are distributed alternately.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By coating the surface of the coating strip and the cooling plate with a foaming layer, the foaming layer can expand after being heated. On the one hand, this increases the contact area between water and air, and on the other hand, the expansion of the foaming layer will squeeze out the scale on the surface, which helps to ensure the cleanliness of the cooling plate surface and improve the cooling speed and cooling effect. Furthermore, the cooperation of the first guide plate and the second guide plate facilitates the increase of the air and water flow speed, avoids channeling phenomenon, and improves the utilization rate of the packing. Ultimately, it solves the problems of poor cooling effect and low packing utilization rate caused by surface scaling in existing devices. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example: See Figure 1-3This utility model discloses a PVC sheet cooling tower packing material with an improved corrugated structure, comprising stacked cooling plates 1, which facilitate the installation of covering strips 2; multiple covering strips 2 are staggered on the top and bottom surfaces of the cooling plates 1, which facilitate the formation of a water film on the surface of the cooling plates 1; the covering strips 2 are equipped with a guiding mechanism and an assembly mechanism to facilitate the stacking of the cooling plates 1, which facilitates the increase of water and air flow rate; the assembly mechanism facilitates the stacking of the cooling plates 1; the covering strips 2 are S-shaped and have a trapezoidal cross-section.

[0019] In this invention, the guiding mechanism includes multiple first guide plates 3 equidistantly and obliquely installed on the coating strip 2 and second guide plates 4 installed at the turning points of the coating strip 2. The first guide plates 3 and the second guide plates 4 facilitate the guiding of water flow. Both the first guide plates 3 and the second guide plates 4 are trapezoidal. The surfaces of the cooling plate 1 and the coating strip 2 are coated with a foaming layer 5. The foaming layer 5 expands when heated, squeezing out scale from the surfaces of the cooling plate 1 and the coating strip 2. The assembly mechanism includes retaining beads 6 fixed to the second guide plate 4 and retaining grooves 7 formed on the second guide plate 4. The cooperation between the retaining beads 6 and the retaining grooves 7 facilitates the stacking of the cooling plates 1 layer by layer. The retaining beads 6 and the retaining grooves 7 are staggered.

[0020] Working principle: In the use of this utility model, the cooling plates 1 are stacked layer by layer through the locking beads 6 and the locking groove 7, and then placed in the cooling tower. When water droplets fall on the surface of the cooling plates 1, the coating strip 2 forms a water film with the cooling plates 1. The first guide plate 3 and the second guide plate 4 can guide the water and air. With the cooperation of the trapezoidal and S-shaped coating strip 2, the contact area between water and air is increased, thereby accelerating the heat exchange efficiency. When the surface of the cooling plates 1 is heated, the foaming layer 5 will expand, squeezing out the scale on the cooling plates 1 and the coating strip 2, and then it will be discharged with the water flow.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
