Description

Technical Field

[0001] The present invention relates to the technical field of cooling towers, and particularly to a cooling device. Background Art

[0002] A cooling tower is a device used to reduce the temperature of circulating cooling water and is widely used in industrial and civil fields. Its core function is to dissipate the heat in the circulating water into the atmosphere through the heat exchange between water and air, thereby reducing the water temperature and ensuring the continuous and effective operation of the cooling system.

[0003] For example, the anti-blocking cooling tower disclosed in the patent document with the publication number CN204373449U includes a main body. An upwardly opening hot air discharge port is formed at the top of the main body, a cold air inlet is provided at the lower part of the main body, and a water collecting pool is provided at the bottom of the main body; a water distribution pipe connected to a hot water addition port is provided in the main body, and the water distribution pipe is provided with nozzles; a water dispersion area is provided below the nozzles in the main body, a water collector is communicated with the water dispersion area, and a cooling area is provided between the water dispersion area and the cold air inlet. Cold air enters the cooling area from the cold air inlet, thereby cooling the hot water in the cooling area. After the cold air is cooled, it forms hot air, and then is discharged from the hot air discharge port to realize the cooling of the circulating water.

[0004] Although the existing cooling tower can realize the cooling of circulating water through cold air, the air needs to be introduced by an induced draft fan provided at the hot air discharge port. When the induced draft fan works, it consumes a large amount of electric energy, thereby increasing the energy consumption of the cooling tower and resulting in a relatively high energy consumption of the cooling tower. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above technical deficiencies and propose a cooling device to solve the technical problem of relatively high energy consumption of the cooling tower in the prior art.

[0006] To achieve the above technical purpose, the present invention adopts the following technical solutions: The present invention provides a cooling device, including: A tower body provided with a cooling chamber, an air inlet, and an air outlet, wherein the air inlet and the air outlet are respectively communicated with both ends of the cooling chamber; A cooling bed installed in the cooling chamber for the water body to be cooled to adhere to; A water turbine fan located at the air outlet; and A pipeline water supply member, the water outlet end of which is connected to the water turbine fan for supplying water to the water turbine fan to drive the water turbine fan to rotate.

[0007] In some embodiments, the pipeline water supply member includes a main water supply pipe, a first water supply branch pipe, and a second water supply branch pipe. The main water supply pipe is located outside the tower body. The first water supply branch pipe is connected to the main water supply pipe and the water turbine fan. The second water supply branch pipe is connected to the main water supply pipe and extends to one side of the cooling bed close to the air outlet.

[0008] In some embodiments, the pipeline water supply member further includes a spray head module. The spray head module is installed on one side of the second water supply branch pipe close to the cooling bed and is used for spraying water towards the cooling bed.

[0009] In some embodiments, the water turbine fan includes a turbine, a blade frame, and a water outlet pipe. The blade frame is arranged at the air outlet. The turbine is connected to the blade frame. The water outlet pipe is connected to the turbine and is arranged in a staggered manner with the second water supply branch pipe. The water outlet pipe can direct the water body discharged from the turbine towards the cooling bed.

[0010] In some embodiments, a plurality of spaced water outlet holes are arranged along the extending direction of the water outlet pipe.

[0011] In some embodiments, the cooling device further includes a water receiving plate. The water receiving plate is located on one side of the cooling bed close to the air inlet, and the water receiving plate is provided with communication holes.

[0012] In some embodiments, the cooling device further includes a gas dispersing plate. The gas dispersing plate is fixed to the inner wall of the cooling chamber and is located on one side of the communication hole close to the cooling bed.

[0013] In some embodiments, the cooling bed is slidably connected to the inner wall of the tower body.

[0014] In some embodiments, the cooling device further includes an adjusting unit. The adjusting unit includes a support ring and a plurality of adjusting support frames. The support ring is fixed to the tower body and is located on one side of the cooling bed close to the air inlet. Each of the adjusting support frames is fixed to the support ring along the circumferential direction of the support ring. Each of the adjusting support frames is threadedly connected with an adjusting screw rod, and the adjusting screw rod abuts against the cooling bed.

[0016] Compared with the prior art, the cooling device provided by the present invention includes a tower body, a cooling bed, a water-wheel blower, and a pipeline water supply member. The tower body is provided with a cooling chamber, an air inlet, and an air outlet. The air inlet and the air outlet are respectively communicated with two ends of the cooling chamber. The cooling bed is installed in the cooling chamber, and the water-wheel blower is located at the air outlet. When the water-wheel blower is started, cold air from the outside can enter the cooling chamber through the air inlet, and then contact with the high-temperature water body attached to the cooling bed, thereby taking away the heat of the high-temperature water body. After the cold air absorbs heat, it forms hot air, which is then discharged from the air outlet, thus realizing the cooling of the high-temperature water body. Since the water-wheel blower serves as an induced draft fan, it can be driven by the water supply of the pipeline water supply member, thereby reducing the energy consumption when introducing air and avoiding excessive energy consumption of the cooling device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] In order to solve the technical problem of high energy consumption of cooling towers in the prior art, an embodiment of the present invention provides a cooling device, which can be used for cooling high-temperature water bodies formed in industrial production, and drives the rotation of the blower by using the potential energy formed in the water supply process, thereby reducing the energy consumption when introducing air.

[0021] It should be noted that the cooling device described in the present invention is used for, but not limited to, high-temperature water bodies, etc. For the convenience of description, in the present invention, only the case where the cooling device is applied to high-temperature water bodies is taken as an example for description, and the principle of the cooling device applied to other types of equipment is essentially the same as that applied to high-temperature water bodies, and will not be elaborated one by one here.

[0022] The cooling device provided by the embodiment of the present invention, such as Figures 1 - 3 shown, includes a tower body 10, a cooling bed 20, a water-wheel blower 30 and a pipeline water supply member 40. The tower body 10 is provided with a cooling chamber 11, an air inlet 12 and an air outlet 13. The air inlet 12 and the air outlet 13 are respectively communicated with both ends of the cooling chamber 11; the cooling bed 20 is installed in the cooling chamber 11 for the water body to be cooled to adhere to; the water-wheel blower 30 is located at the air outlet 13; the water outlet end of the pipeline water supply member 40 is connected to the water-wheel blower 30 for supplying water to the water-wheel blower 30 to drive the water-wheel blower 30 to rotate.

[0023] In this embodiment, by setting the tower body 10, the cooling bed 20, the water-wheel blower 30 and the pipeline water supply member 40, the tower body 10 is provided with a cooling chamber 11, an air inlet 12 and an air outlet 13. The air inlet 12 and the air outlet 13 are respectively communicated with both ends of the cooling chamber 11. The cooling bed 20 is installed in the cooling chamber 11, and the water-wheel blower 30 is located at the air outlet 13. When the water-wheel blower 30 is started, external cold air can enter the cooling chamber 11 through the air inlet 12, and then contact the high-temperature water body adhering to the cooling bed 20, so as to take away the heat of the high-temperature water body. After the cold air absorbs heat, it forms hot air, and then is discharged from the air outlet 13, thereby realizing the cooling of the high-temperature water body. Since the water-wheel blower 30 is used as an induced draft fan, it can be driven by the water supply of the pipeline water supply member 40, thereby reducing the energy consumption when introducing air and avoiding excessive energy consumption of the cooling device.

[0024] In this embodiment, since the high-temperature water body contains a large hydraulic pressure when it is formed, the high-temperature water body enters the water-wheel blower 30 through the pipeline water supply member 40, and through its own hydraulic pressure, it can drive the water-wheel blower 30 to rotate, and thus there is no need to consume additional electric energy to drive the water-wheel blower 30.

[0025] In this embodiment, as Figure 1 and 3 shown, the tower body 10 is further provided with a drain port 14. The drain port 14 and the air inlet 12 are both arranged at the bottom end of the tower body 10, and the air inlet 12 is located above the drain port 14 to prevent the cooled water body from being discharged from the air inlet 12.

[0026] In one of the embodiments, as Figure 3As shown, the cooling bed 20 includes an annular frame 21 and a plurality of folded plates 22. The annular frame 21 is connected to the inner wall of the cooling chamber 11, and each folded plate 22 is fixedly arranged on the annular frame 21 at intervals along the radial direction of the annular frame 21. Specifically, the high-temperature water bodies supplied by the nozzle module 44 of the pipeline water supply member 40 and the water outlet pipe 33 will adhere to each folded plate 22. The air introduced from the air inlet 12 into the air outlet 13 will enter the gaps between the folded plates 22. During the flow of the cold air through the gaps between the folded plates 22, it will come into full contact with the high-temperature water bodies adhering to the folded plates 22, so as to achieve efficient cooling of the high-temperature water bodies.

[0027] In this embodiment, as Figure 3 shown, the height of the annular frame 21 is higher than that of each folded plate 22 to prevent the water body from entering the gap between the cooling bed 20 and the cooling chamber 11 from the folded plates 22.

[0028] In this embodiment, as Figure 1 shown, a mounting frame 15 is fixed to the inner wall of the cooling chamber 11. The mounting frame 15 is located on the side of the air outlet 13 close to the cooling bed 20, and the water-wheel fan 30 is fixed to the mounting frame 15.

[0029] In this embodiment, as Figure 1 and 3 shown, the water-wheel fan 30 includes a turbine 31 and a blade frame 32. The blade frame 32 is arranged at the air outlet 13, the turbine 31 is connected to the blade frame 32, and the pipeline water supply member 40 is connected to the turbine 31. Specifically, by supplying water into the turbine 31, the pipeline water supply member 40 can drive the turbine 31 to rotate, thereby driving the blade frame 32 to rotate. Through the rotation of the blade frame 32, the introduction of cold air from the air inlet 12 and the discharge from the air outlet 13 are realized.

[0030] In this embodiment, the turbine 31 includes a housing and a turbine structure arranged inside the housing. The pipeline water supply member 40 drives the internal turbine structure to rotate by introducing high-temperature water bodies into the housing. After the high-temperature water bodies flow out of the housing, they can enter the cooling bed 20 for further cooling.

[0031] In one of the embodiments, as Figures 1 - 3As shown in the figure, the pipeline water supply member 40 includes a main water supply pipe 41, a first water supply branch pipe 42, and a second water supply branch pipe 43. The main water supply pipe 41 is located outside the tower body 10. The first water supply branch pipe 42 is connected to the main water supply pipe 41 and the water turbine blower 30. The second water supply branch pipe 43 is connected to the main water supply pipe 41 and extends to one side of the cooling bed 20 near the air outlet 13. Specifically, after the high-temperature water body enters the main water supply pipe 41, it is distributed to the first water supply branch pipe 42 and the second water supply branch pipe 43. The first water supply branch pipe 42 supplies the high-temperature water body to the water turbine blower 30, and the second water supply branch pipe 43 introduces the high-temperature water body. Since the just-introduced high-temperature water body has a large potential energy, while realizing the supply of the high-temperature water body to the cooling bed 20, the potential energy of the high-temperature water body can be used to drive the water turbine blower 30.

[0032] In this embodiment, the number of the second water supply branch pipes 43 can be adaptively set according to the supply volume and supply pressure of the high-temperature water body.

[0033] In one of the embodiments, as Figure 3 shown, the pipeline water supply member 40 further includes a spray head module 44. The spray head module 44 is installed on one side of the second water supply branch pipe 43 close to the cooling bed 20 and is used for spraying water toward the cooling bed 20. Specifically, since the just-introduced high-temperature water body has a large potential energy, after the high-temperature water body enters the spray head module 44 through the second water supply branch pipe 43, under the action of the potential energy of the high-temperature water body itself, the spray head module 44 can form a spray, so that the high-temperature water body can be evenly sprayed onto the cooling bed 20, thereby accelerating the cooling of the high-temperature water body.

[0034] In this embodiment, the spray head module 44 is several spray heads installed at intervals on the second water supply branch pipe 43, and the cooling bed 20 is evenly sprayed through the spraying of each spray head.

[0035] In one of the embodiments, as Figure 3 shown, the water turbine blower 30 further includes a water outlet pipe 33. The water outlet pipe 33 is connected to the turbine 31 and is arranged in a staggered manner with the second water supply branch pipe 43. The water outlet pipe 33 can direct the water body discharged from the turbine 31 to the cooling bed 20. Specifically, after the high-temperature water body drives the turbine 31 to rotate by using its own potential energy, it enters the water outlet pipe 33, and then leads to the cooling bed 20 from the water outlet pipe 33. Since the water outlet pipe 33 is arranged in a staggered manner with the second water supply branch pipe 43, at the junction of the staggered water outlet pipe 33 and the second water supply branch pipe 43, the high-temperature water body can be evenly distributed to the cooling bed 20, improving the cooling efficiency of the high-temperature water body.

[0036] In one of the embodiments, a plurality of spaced water outlet holes are arranged along the extending direction of the water outlet pipe 33. Specifically, the high-temperature water body entering the water outlet pipe 33 can pass out through each water outlet hole, so as to spray the high-temperature water body onto the cooling bed 20.

[0037] In one embodiment, the cooling bed 20 is slidably connected to the inner wall of the tower body 10. Specifically, by the sliding connection between the cooling bed 20 and the inner wall of the tower body 10, the distance between the cooling bed 20 and the second water supply pipe and the water outlet pipe 33 can be adjusted, so that the high-temperature water body can better adhere to the cooling bed 20.

[0038] In one embodiment, as Figure 3 shown, the cooling device further includes an adjusting unit 50. The adjusting unit 50 includes a support ring 51 and a plurality of adjusting support frames 52. The support ring 51 is fixed to the tower body 10 and is located on the side of the cooling bed 20 close to the air inlet 12. Each adjusting support frame 52 is fixed to the support ring 51 along the circumferential direction of the support ring 51. Each adjusting support frame 52 is threadedly connected with an adjusting screw 53, and the adjusting screw 53 abuts against the cooling bed 20. Specifically, the cooling bed 20 can be supported by the adjusting screw 53. By screwing the adjusting screw 53, the cooling bed 20 can be driven to slide, realizing the adjustment of the cooling bed 20. Therefore, the adjusting unit 50 can not only stabilize the cooling bed 20, but also realize the adjustment of the height of the cooling bed 20.

[0039] In one embodiment, as Figure 3 shown, the cooling device further includes a water receiving plate 60. The water receiving plate 60 is located on the side of the cooling bed 20 close to the air inlet 12, and the water receiving plate 60 is provided with a communication hole 61. Specifically, the water body flowing out of the cooling bed 20 will enter the water receiving plate 60 and be received by the water receiving plate 60. The water body received by the water receiving plate 60 will flow into the bottom of the tower body 10 from the communication hole 61 and then be discharged from the drain port 14. The cold air entering the cooling chamber 11 will enter the gap between the water receiving plate 60 and the cooling bed 20 from the communication hole 61, and then diffuse in the gap between the water receiving plate 60 and the cooling bed 20. The diffused cold air will contact the water body of the water receiving plate 60 to further cool the water body, and then the diffused air will be evenly distributed to the cooling bed 20 to cool the water body of the cooling bed 20. Through the setting of the receiving plate, not only can the secondary cooling of the high-temperature water body be realized, but also the cold air can be evenly diffused to the cooling bed 20 to ensure the efficient cooling of the high-temperature water body.

[0040] In one embodiment, as Figure 3 shown, the cooling device further includes a gas diffusing plate 70. The gas diffusing plate 70 is fixed to the inner wall of the cooling chamber 11 and is located on the side of the communication hole 61 close to the cooling bed 20. Specifically, on the one hand, the gas diffusing plate 70 can prevent the water body flowing out of the cooling bed 20 from directly entering the communication hole 61. On the other hand, it can prevent the cold air entering from the communication hole 61 from being blocked, so as to prevent the cold air from directly entering the cooling bed 20, facilitating the uniform diffusion of the cold air to the cooling bed 20.

[0041] For a better understanding of the present invention, the following is combined with Figures 1 to 3The technical solution of the present invention will be described in detail: When cooling high-temperature water, the high-temperature water is introduced into the water supply main pipe 41, and then distributed to the first water supply branch pipe 42 and the second water supply branch pipe 43 through the water supply main pipe 41. The first water supply branch pipe 42 supplies the high-temperature water into the water wheel blower 30, driving the blade frame of the water wheel blower 30 to rotate, thereby driving cold air to enter the cooling chamber 11 from the air inlet 12, then entering the gap between the cooling bed 20 and the water receiving plate 60 through the communication hole 61, then entering the gaps between the folded plates 22 of the cooling bed 20, and finally discharging from the air outlet 13. After the high-temperature water passes through the water wheel blower 30, it enters the water outlet pipe 33, and then discharges from the water outlet holes of the water outlet pipe 33 to the cooling bed 20. The high-temperature water entering the second water supply branch pipe 43 is sprayed onto the cooling bed 20 through the nozzle module 44. The high-temperature water entering the cooling bed 20 enters the gaps between the folded plates 22, fully contacts the cold air between the folded plates 22, is cooled by the cold air, then is received by the water receiving plate 60, is cooled again by the water receiving plate 60, and finally enters the bottom of the tower body 10 through the communication hole 61 and is finally discharged from the drain outlet 14.

[0042] The specific embodiments of the present invention described above do not constitute a limitation to the protection scope of the present invention.
