Description

Technical Field

[0001] The utility model relates to the technical field of cooling water towers, in particular to a vacuum cooling water tower. Background Art

[0002] A cooling tower is a device that uses the principle of water evaporation and heat absorption to reduce water temperature. It is widely used in industrial fields such as electricity, chemical industry, steel, and pharmaceuticals. Traditional cooling towers use a spray system to spray hot water onto the filler and use air flow to remove heat to achieve water cooling.

[0003] After searching, a Chinese patent with publication number CN216558391U discloses a high-efficiency cooling tower, comprising: a tower body, the interior of which is hollow and has a cooling reaction chamber; a water distributor, the input end of which is connected to the waste hot water outside, and the output end of which is flatly laid above the cooling reaction chamber and is used to evenly spray the waste hot water downward; a heat exchange radiator, which is mounted above the cooling reaction chamber, and the output end of the water distributor is passed through the heat exchange radiator and exchanges heat with the heat exchange radiator; a filler, which is mounted in the middle of the cooling reaction chamber to expand the contact area of the waste hot water and form a water film; and an airflow generating fan, which is mounted on the top of the cooling reaction chamber and is used to draw air from the outside of the tower body and exchange heat with the waste hot water on the filler.

[0004] In the above technology, by adding a heat exchange radiator, the cooling of waste hot water can be accelerated and the cooling time of waste hot water can be shortened. However, in actual use, after long-term use, the temperature of the coolant inside the heat exchange radiator will gradually increase, thereby reducing the cooling effect. In addition, after the hot water forms a water film through the filler, it will quickly fall to the bottom of the tower body. Therefore, it is difficult for the wind flow to carry away all the heat, resulting in incomplete cooling.

[0005] To this end, the utility model provides a vacuum cooling water tower. Utility Model Content

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problem of poor cooling effect of existing cooling towers in the prior art.

[0007] In order to solve the above technical problems, the utility model provides a vacuum cooling water tower, including a tower body, three spray pipes are fixedly connected to the inside of the tower body, and a plurality of filler sheets are respectively arranged inside the tower body below the three spray pipes, and the two ends of the filler sheets are respectively fixedly connected to support columns, and the support columns are fixedly connected to the tower body. A flow cavity is provided inside the filler sheet, and a plurality of turning cavities are provided inside the support column, and the flow cavity is connected to the turning cavity. The two ends of the tower body side wall are respectively fixedly connected with a conduit, and the upper and lower ends of the conduit are respectively connected to the turning cavity, and the flow cavity, the turning cavity and the conduit cooperate to form a one-way flow channel, and a water inlet is provided at one end of the tower body side wall, and a water outlet is provided at the other end of the tower body side wall, and the water inlet and the water outlet are both connected to the one-way flow channel.

[0008] In one embodiment of the present invention, a water storage tank is further included. The bottom of the water storage tank is connected to a first water pump. The output end of the first water pump is connected to a diversion pipe. The three spray pipes are all connected to the diversion pipe.

[0009] In one embodiment of the present invention, a vacuum pump is fixedly connected to the top of the tower body, a water collecting tank is provided at the bottom of the tower body, and a material receiving hopper is provided at the top of the water collecting tank.

[0010] In one embodiment of the present invention, one end of the water collection tank is connected to a drain pipe, one end of the drain pipe extends to the outside of the tower body and is connected to a second water pump, and the output end of the second water pump is connected to the water storage tank.

[0011] In one embodiment of the present invention, the output end of the second water pump is connected to a heat dissipation pipe, the heat dissipation pipe is connected to the water storage tank, and a plurality of fins are fixedly connected to the surface of the heat dissipation pipe.

[0012] In one embodiment of the present invention, the output end of the second water pump is connected to a first connecting pipe, the first connecting pipe is connected to a heat dissipation pipe, one end of the heat dissipation pipe is connected to a second connecting pipe, and one end of the second connecting pipe is connected to the top of the water storage tank.

[0015] The above technical solution of the utility model has the following advantages compared with the prior art:

[0016] The utility model is described in that a flow cavity is provided inside the filler sheet and a deflection cavity is provided inside the support column, so that hot water can flow in an S-shaped state in the flow cavity and the deflection cavity. At the same time, the one-way flow channel formed by the two conduits allows the hot water to flow in a single direction, avoiding the situation where some hot water is retained during the flow process, thereby ensuring that the hot water can be evenly cooled. In addition, the design of three spray pipes can cool the hot water in the one-way flow channel three times to ensure that the hot water can be thoroughly cooled. The vacuum pump provided on the top of the tower body can evacuate the interior of the tower body. Under the vacuum environment, the pressure inside the tower body will be reduced, thereby reducing the boiling point of water, so that the water sprayed from the spray pipe can evaporate at a lower temperature. During the evaporation process, it can absorb a large amount of heat from the filler sheet, thereby achieving efficient cooling of the hot water. In addition, during the cooling process, excess cooling water will drip into the water collection tank for collection. At this time, the collected cooling water can be transported to the heat dissipation pipe by the second water pump for heat dissipation, thereby ensuring the cooling effect of the cooling water. The design of the fan and fins can accelerate the heat dissipation speed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1 to 8 As shown, a vacuum cooling water tower of the present invention comprises a tower body 1, three spray pipes 2 are fixedly connected to the inside of the tower body 1, a plurality of filler sheets 3 are respectively arranged below the three spray pipes 2 inside the tower body 1, support columns 4 are respectively fixedly connected at both ends of the filler sheets 3, the support columns 4 are fixedly connected to the tower body 1, a flow cavity 5 is provided inside the filler sheet 3, a plurality of steering cavities 6 are provided inside the support columns 4, the flow cavity 5 is communicated with the steering cavity 6, a conduit 7 is respectively fixedly connected to the two ends of the side wall of the tower body 1, the upper and lower ends of the conduit 7 are respectively communicated with the steering cavity 6, the flow cavity 5, the steering cavity 6 and the conduit 7 cooperate to form a one-way flow channel, a water inlet 8 is provided at one end of the side wall of the tower body 1, a water outlet 9 is provided at the other end of the side wall of the tower body 1, and the water inlet 8 and the water outlet 9 are both communicated with the one-way flow channel;

[0029] In this embodiment, the three spray pipes 2 in the tower body 1 are equidistantly distributed up and down, and a plurality of spray ports are provided at the bottom of the spray pipe 2. The spray pipe 2 is arranged in an S-shaped winding manner, thereby expanding the spray range of the spray pipe 2. In addition, a flow cavity 5 is provided inside the packing piece 3, and a turning cavity 6 is provided in the support column 4, so that the hot water can flow in an S-shaped state in the flow cavity 5 and the turning cavity 6. At the same time, the one-way flow channel formed by the two conduits 7 allows the hot water to flow in a single direction, avoiding the situation where some hot water is retained during the flow process, thereby ensuring that the hot water can be evenly cooled. The turning cavities 6 in the two support columns 4 are staggered with each other, thereby ensuring that the hot water can turn and flow in the flow cavity 5 in one packing piece 3. When the flow cavity 5 in the adjacent packing piece 3 is turned, the conduits 7 on both sides of the flow cavity 5 can flow in the flow cavity 5 in the adjacent packing piece 3. The ends are respectively connected with the steering cavity 6 at one end of the upper and lower support columns 4. The height of the water inlet 8 is the same as the height of the top filler sheet 3, and is connected with the steering cavity 6 in one of the support columns 4. The height of the water outlet 9 is the same as the height of the bottom filler sheet 3, and is connected with the steering cavity 6 in one of the support columns 4. When cooling, hot water is first injected into the steering cavity 6 in the support column 4 through the water inlet 8. At this time, the hot water will flow in the one-way flow channel formed by the flow cavity 5 in the filler sheet 3, the steering cavity 6 in the support column 4 and the conduit 7. At this time, cooling water is injected into the three spray pipes 2, and the cooling water will be sprayed out from the water nozzle and drip onto the surface of the filler sheet 3, thereby absorbing the heat of the hot water inside the filler sheet 3, thereby realizing the cooling of the hot water, and the cooled hot water will be discharged through the water outlet 9.

[0030] like Figure 1 and Figure 2 As shown, it also includes a water storage tank 25, the bottom of the water storage tank 25 is connected to the first water pump 10, the output end of the first water pump 10 is connected to the diversion pipe 11, and the three spray pipes 2 are all connected to the diversion pipe 11;

[0031] In this embodiment, cooling water is pre-stored in the water storage tank 25. When cooling is performed, the first water pump 10 is turned on. Under the action of the first water pump 10, the cooling water will flow into the three spray pipes 2 through the diversion pipe 11, thereby achieving a spraying effect.

[0032] like Figure 4 As shown, a vacuum pump 12 is fixedly connected to the top of the tower body 1, a water collecting tank 13 is provided at the bottom of the tower body 1, and a material receiving hopper 14 is provided on the top of the water collecting tank 13;

[0033] In this embodiment, the vacuum pump 12 can perform vacuum treatment on the interior of the platform. Under the vacuum environment, the internal pressure of the tower body 1 will decrease, thereby reducing the boiling point of water, so that the water sprayed from the spray pipe 2 can evaporate at a lower temperature. During the evaporation process, a large amount of heat on the filler sheet 3 can be absorbed, thereby achieving efficient cooling of the hot water. In addition, during the spraying process, excess cooling water will drip into the water collecting tank 13 for collection for subsequent use. The cooling water can be accurately flowed into the water collecting tank 13 through the receiving hopper 14.

[0034] like Figure 2 and Figure 4 As shown, one end of the water collecting tank 13 is connected to a drain pipe 15, one end of the drain pipe 15 extends to the outside of the tower body 1 and is connected to a second water pump 16, and the output end of the second water pump 16 is connected to the water storage tank 25;

[0035] In this embodiment, the design of the drain pipe 15 allows the second water pump 16 to smoothly pump out the cooling water in the water collection tank 13 and transport it to the water storage tank 25 for subsequent use.

[0036] like Figure 2 As shown, the output end of the second water pump 16 is connected to a heat dissipation pipe 17, which is connected to the water storage tank 25. A plurality of fins 18 are fixedly connected to the surface of the heat dissipation pipe 17;

[0037] In this embodiment, since the cooling water absorbs the heat of the hot water inside the filler sheet 3 during the spray cooling process, the temperature of the cooling water itself will increase. Therefore, the cooling water is dissipated by the design of the heat dissipation pipe 17 to ensure the subsequent cooling effect of the cooling water. The fins 18 arranged on the surface of the heat dissipation pipe 17 can increase the heat exchange area, thereby accelerating the heat dissipation speed. Moreover, the heat dissipation pipe 17 is arranged in an S-shaped winding manner, which can further increase the number of fins 18, thereby further accelerating the heat dissipation speed.

[0038] like Figure 2 As shown, the output end of the second water pump 16 is connected to the first connecting pipe 19, the first connecting pipe 19 is connected to the heat dissipation pipe 17, one end of the heat dissipation pipe 17 is connected to the second connecting pipe 20, and one end of the second connecting pipe 20 is connected to the top of the water storage tank 25;

[0039] In this embodiment, the design of the first connecting pipe 19 allows the output end of the second water pump 16 to be smoothly connected to the heat dissipation pipe 17 , and the design of the second connecting pipe 20 allows the heat dissipation pipe 17 to be smoothly connected to the water storage tank 25 .

[0040] like Figure 1 As shown, the bottom center of the water storage tank 25 is connected to a third connecting pipe 21, which is connected to the input end of the first water pump 10. A water inlet 22 is provided at one end of the top of the water storage tank 25;

[0041] In this embodiment, the water tank 25 can be smoothly connected to the input end of the first water pump 10 through the third connecting pipe 21. Since some cooling water will evaporate during the spraying process, it is necessary to regularly add cooling water to the water tank 25. Therefore, the design of the water inlet 22 facilitates the addition of cooling water to the water tank 25. In actual use, a water level sensor can be installed in the water tank 25 to facilitate the understanding of the amount of cooling water in the water tank 25.

[0042] like Figure 3 As shown, the tower body 1 is fixedly connected to the side wall of one end of the heat dissipation pipe 17 with an air guide cover 23, and the tower body 1 is fixedly connected to the center of the air guide cover 23 with a fan 24;

[0043] In this embodiment, the fan 24 is designed to increase the flow rate of air on the surface of the heat pipe 17 and the fin 18, thereby accelerating the heat dissipation effect. The wind guide cover 23 is designed to allow the wind flow generated by the fan 24 to blow accurately toward the heat pipe 17.

[0044] Working principle: first inject hot water into the steering cavity 6 in the support column 4 through the water inlet 8, and then the hot water will flow in the one-way flow channel formed in the flow cavity 5 in the filler sheet 3, the steering cavity 6 in the support column 4 and the conduit 7. When cooling, turn on the first water pump 10. Under the action of the first water pump 10, the cooling water will flow into the three spray pipes 2 respectively through the diversion pipe 11. At this time, the cooling water will be sprayed out from the water nozzle at the bottom of the spray pipe 2 and drip onto the surface of the filler sheet 3, thereby absorbing the heat of the hot water inside the filler sheet 3, thereby realizing the cooling of the hot water. In this process, turn on the vacuum pump 12, and the vacuum pump 12 can perform vacuum treatment on the inside of the platform. Under the vacuum environment, the internal pressure of the tower body 1 will be reduced, thereby reducing the boiling point of water, making the spray The water sprayed from the shower pipe 2 can evaporate at a lower temperature, and can absorb a large amount of heat from the filler sheet 3 during the evaporation process, thereby achieving efficient cooling of the hot water. In addition, during the spraying process, excess cooling water will drip into the water collection tank 13 for collection for subsequent use. When the water collection tank 13 is full of cooling water, the second water pump 16 is turned on at this time. The second water pump 16 can smoothly extract the cooling water in the water collection tank 13 and transport it to the heat dissipation pipe 17. At this time, the fan 24 is turned on. The wind flow generated by the fan 24 can increase the flow rate of the air on the surface of the heat dissipation pipe 17 and the fin 18, thereby accelerating the heat dissipation effect, so that the cooling water has a better cooling effect in the subsequent spraying process. Finally, the cooled hot water will be discharged through the water outlet 9.

[0045] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
