Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower appliances, in particular to a high-efficiency cooling tower with different filler combinations. Background Art

[0002] The cooling tower uses water as a circulating cooling medium, absorbs heat from a system and discharges it into the atmosphere to cool the circulating water system. During use, about 70% of the heat dissipation occurs in the filler.

[0003] The prior art discloses a patent CN201364079Y, which is composed of overlapping thin film filler sheets, each of which is provided with a corresponding yin-yang joint part, and two adjacent filler sheets are inserted and joined through the yin-yang joint part, and a large number of folds are formed on each filler sheet, and the folded wave surface is composed of a large number of continuous, convex small arc surfaces, and a water-breaking node is provided on the fold. Compared with the existing cooling tower thin film filler, the high heat transfer cooling tower thin film filler has an increased heat transfer area, and the heat transfer and mass transfer coefficients are greatly improved, so the thermal performance is significantly improved. Due to the good thermal performance of the filler, its design air volume can be reduced accordingly. Under the condition of low water density, its water section resistance will be further reduced, and the design value of the filler resistance has a larger reduction than the conventional design.

[0004] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, which are mainly manifested in the following aspects:

[0005] At present, most of the multi-layer film fillers on the market are arranged to achieve the cooling effect. On the one hand, there is uneven water distribution of the nozzles, resulting in high-water and low-water areas in the fillers;

[0006] On the other hand, as the cooling tower runs for a long time, the film filler will become clogged and scaled, which will seriously affect the thermal performance of the cooling tower.

[0007] In summary, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] In view of the defects in the prior art, the utility model provides a high-efficiency cooling tower with different filler combinations to solve the problem that, on the one hand, the cooling tower in traditional technology has uneven water distribution from the nozzle, resulting in the presence of high-water and low-water areas in the filler; on the other hand, as the cooling tower runs for a long time, the film filler will become clogged and scaled, which seriously affects the thermal performance of the cooling tower.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] A high-efficiency cooling tower with different filler combinations comprises a tower body, wherein a water distribution device is arranged in the tower body, and a filler support frame is also arranged in the tower body, and a grid filler and a film filler are arranged in parallel from top to bottom on the filler support frame.

[0011] As an optimized solution, a plurality of the film fillers are arranged in parallel from top to bottom, and adjacent film fillers are arranged in a staggered manner.

[0012] As an optimized solution, the filler support frame is vertically raised and lowered to adjust the distance between the grid filler, the film filler and the water distribution device.

[0013] As an optimized solution, a plurality of top columns are arranged around the inner wall of the tower body, and the top columns are arranged to be lifted vertically, and the upper ends of the top columns are connected to the lower ends of the filling support frames.

[0014] As an optimized solution, a support plate is horizontally fixedly connected to the inner wall of the tower body corresponding to each of the top columns, the top columns are threadedly connected to the support plate, a turntable is fixedly connected to the lower end of the filling support frame corresponding to each of the top columns, and the upper end of the top column is fixedly connected to the rotating end of the turntable.

[0015] As an optimized solution, the outer wall of the top column is provided with an external thread, and the support plate is provided with a threaded hole matching the external thread.

[0016] As an optimized solution, a driving sleeve is rotatably provided on the upper end surface of the support plate, and the driving sleeve is provided with a light hole that is sleeved on the top column. A driving block is vertically fixed on the upper edge of the light hole, and a driving groove is vertically provided on the upper edge of the top column, and the driving block is slidably constrained in the driving groove.

[0017] As an optimized solution, a gear ring is coaxially fixed to the outer wall of the drive sleeve, a drive motor is fixed to the upper end surface of the support plate, and a rack meshing with the gear ring is fixed to the output end of the drive motor.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The circulating cooling water is sprayed through the nozzle of the water distribution system and first falls on the mesh filler. Under the action of the mesh filler, the spray water is broken into countless small water droplets and scattered more evenly on the film filler to form a uniform and effective water film, thereby increasing the heat dissipation performance of the filler and improving the overall performance of the cooling tower;

[0020] In addition, the mesh filler has better anti-clogging and anti-scaling capabilities than the film filler, which can effectively increase the service life of the cooling tower filler, thereby ensuring the operating effect;

[0021] The filler support frame can be raised and lowered vertically, so that when the nozzle of the water distribution system is blocked or the flow is insufficient, the distance between the entire filler and the water distribution system can be adjusted to improve the heat dissipation efficiency.
