Description

Technical Field

[0001] The present invention relates to a cooling water tower, in particular to a cooling water tower with a hydroelectric power generation unit. Background Art

[0002] A cooling tower is a device that cools water, in which the water exchanges heat with the passing air, causing the water temperature to drop. It is widely used in air conditioning circulating water systems and industrial circulating water systems.

[0003] Cooling water tower structure: The water to be cooled is sprayed downward through a pipe on the top of the water tower body. In addition, there is a hair dryer on the wall of the water tower to blow air in, and there is a large exhaust fan on the top to draw air out of the top of the tower, which is conducive to air flow and accelerates the cooling of the water. There are tortuous and hollow heat dissipation plates made of PVC glue above and below the spraying pipe to increase the heat dissipation time of water droplets. It is designed in this shape because the hyperbolic shape is conducive to convection heat exchange between water and air.

[0004] However, the current functional design of cooling water towers is to solve the technical problem of how to manually or automatically filter impurities and remove scale in water. For example, the patent application No. 096212528 of Taiwan, China, for a "cooling water tower with the function of separating mud and sand in water" rarely involves carbon reduction technology and resource saving design. Therefore, how to develop a cooling water tower with a hydropower unit is a technical problem that needs to be solved urgently. Summary of the invention

[0005] The object of the present invention is to provide a cooling water tower with a hydroelectric power generation unit.

[0006] To achieve the aforementioned purpose, the present invention is a cooling water tower with a hydroelectric power generation unit, comprising: a water tower body having a water collecting trough, the water collecting trough being provided with a partition to form a water collecting trough area and a power generation trough area adjacent to the water collecting trough area; a sprinkler disposed in the water tower body and located above the water collecting trough area; a water guide plate disposed in the water tower body and located between the water collecting trough and the sprinkler, and having a water guide corresponding to the sprinkler, and a water outlet connected to the water guide and located above the water collecting trough area; and a hydroelectric power generation unit disposed in the power generation trough area of ​​the water tower body and adjacent to the partition, when water in the water collecting trough area flows through the partition and flows into the power generation trough area, the water flows through the hydroelectric power generation unit, and the hydroelectric power generation unit generates electricity through the height difference of the water.

[0007] The utility model has the following effects: by separating the water collecting tank area of ​​the water tower body into the water collecting tank area and the power generating tank area, and matching the sprinkler, the water guide plate and the hydroelectric power generating unit design, the water flowing out of the sprinkler can be guided by the water guide plate to the water collecting tank area. When the water collecting tank area is full of water, the water in the water collecting tank area will flow through the partition part and flow into the power generating tank area. At this time, the water flowing into the power generating tank area will flow through the hydroelectric power generating unit. The hydroelectric power generating unit generates electricity through the height difference of the water. Accordingly, the utility model can directly convert the cooling water of the cooling water tower that has been cooled into electrical energy, and store the generated electrical energy or use it for other loads, which has the effect of energy saving and environmental protection.

[0008] Preferably, the hydroelectric power generation unit includes a shell, a generator and a spiral blade. The shell is arranged in the power generation trough area and abuts against the partition part, and has a water inlet part and a water outlet part lower than the water inlet part. The generator has a power generation module and a power generation shaft inserted in the shell. The spiral blade can be rotatable in situ in the shell and is fixed to the power generation shaft. When the water in the sump area flows through the partition part and flows into the power generation trough area, the water will flow into the shell from the water inlet part and out from the water outlet part, and at the same time drive the spiral blade to rotate.

[0009] Preferably, the hydroelectric unit includes a shell, a generator and a runner blade. The shell is arranged in the power generation trough area and adjacent to the partition part, and has a water inlet portion against the partition part and a water outlet portion lower than the water inlet portion. The generator has a power generation module and a power generation shaft inserted in the shell. The runner blade is rotatable in situ in the shell and fixed to the power generation shaft. When the water in the sump area flows through the partition part and flows into the power generation trough area, the water will flow into the shell from the water inlet portion and out from the water outlet portion, and at the same time drive the runner blade to rotate.

[0010] Preferably, it also includes a water pumping motor, which is arranged in the power generation tank area of ​​the water tower body or outside the water tower body.

[0038] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Before presenting a detailed description, it should be noted that in the following description, similar components and part names are represented by the same reference numerals.

[0040] See also Figure 1 and Figure 2 As shown, a first embodiment of the present invention provides a cooling water tower with a hydroelectric power generation unit, which is mainly composed of a water tower body 10, a sprinkler 20, a water guide plate 30, a hydroelectric power generation unit 40, and a pumping motor 50, wherein:

[0041] The water tower body 10 is provided with a water collecting tank 11 at its bottom, and the water collecting tank 11 is provided with a partition 12 to form a water collecting tank area 111 and a power generation tank area 112 adjacent to the water collecting tank area 111. In addition, a fan 13 for air convection is provided on the top of the water tower body 10, and porous heat sinks 14 for heat dissipation are provided at intervals on the left and right sides of the inner side of the water tower body 10; since the fan 13 and the heat sink 14 are both conventional components, they are not described in detail.

[0042] The sprinkler 20 is disposed in the water tower body 10 and above the water collection tank area 111 ; the sprinkler 20 receives high-temperature cooling water from the air-conditioning system and sprinkles the water; since the sprinkler 20 is a conventional component, it will not be described in detail.

[0043] The water guide plate 30 is obliquely disposed in the water tower body 10 and is located between the water collection tank 11 and the sprinkler 20, and has a water guide portion 31 corresponding to the sprinkler 20, and a water outlet 32 ​​connected to the water guide portion 31 and located above the water collection tank area 111; the water guide portion 31 is used to receive the water output by the sprinkler 20 and guide the water to the water outlet 32, allowing the water to flow into the water collection tank area 111.

[0044] The hydroelectric power generation unit 40 is arranged in the power generation trough area 112 of the water tower body 10 and is adjacent to the partition 12. When the water in the water collection trough area 111 flows through the partition 12 and flows into the power generation trough area 112, the water flows through the hydroelectric power generation unit 40, and the hydroelectric power generation unit 40 generates electricity through the height difference of the water. In this embodiment, the hydroelectric power generation unit 40 includes a shell 41, a generator 42 and a spiral blade 43. The shell 41 is tubular and is arranged in the power generation trough area 112 and is inclined against the partition 12. It has a water inlet part 411 and a water outlet part 412 lower than the water inlet part 411, so that a height difference is generated between the water inlet part 411 and the water outlet part 412. At the same time, the water inlet part 411 is located in the water collection trough area 111, but it is not used as The generator 42 has a power generation module 421 and a power generation shaft 422 connected to the power generation module 421 and inserted into the shell 41; the spiral blade 43 can be rotatably arranged in the shell 41 and fixedly arranged on the power generation shaft 422. When the water in the water collection trough area 111 flows through the partition 12 and flows into the power generation trough area 112, the water will flow into the shell 41 from the water inlet 411 and flow out from the water outlet 412, and at the same time drive the spiral blade 43 to rotate, and the rotating spiral blade 43 will synchronously drive the power generation shaft 422 to move, thereby enabling the generator 42 to generate electricity.

[0045] The water pumping motor 50 is disposed in the power generation tank area 112 of the water tower body 10, but the present invention is not limited thereto. The water pumping motor 50 may also be disposed outside the water tower body 10 and connected to the power generation tank area 112 of the water tower body 10 through a pipeline to pump water in the power generation tank area 122 to the cooling water circulation channel of the air conditioning system, but the present invention is not limited thereto. In the present embodiment, the water pumping motor 50 is electrically connected to the generator 42 so that part of the electricity required for the operation of the water pumping motor 50 can be provided by the generator 42.

[0046] The above is a description of the main components of the first embodiment of the present invention. The operation mode and effect of the present invention are described as follows:

[0047] When the sprinkler 20 sends the water to be cooled (such as Figure 2When the water is sprayed downward (as shown by the arrow), the water will first be received by the water guide portion 31 of the water guide plate 30 (this can be regarded as the first cooling of the water), and the received water will be guided to the water outlet 32, so that the water flows into the water collection tank area 111. When the water collection tank area 111 is full of water, the water in the water collection tank area 111 will flow through the partition 12 and flow into the power generation tank area 112. At this time, the water flowing into the power generation tank area 112 will flow through the hydroelectric power generation unit 40. Furthermore, the water will flow from the inlet The water inlet 411 flows into the shell 41 and flows out from the water outlet 412, and at the same time drives the spiral blade 43 to rotate. The rotating spiral blade 43 will synchronously drive the power generation shaft 422 to move, thereby enabling the power generation module 421 to generate electricity, that is, the hydroelectric power generation unit 40 generates electricity through the height difference of water. Accordingly, the present invention can directly convert the cooling water that has been cooled by the cooling tower into electrical energy, and store the generated electrical energy or use it for other loads, which has the effect of energy saving and environmental protection.

[0048] It is worth mentioning that, since the present embodiment electrically connects the water pumping motor 50 to the generator 42, the present invention can directly convert the cooling water cooled by the cooling tower into electrical energy. Therefore, part of the electricity required for the operation of the water pumping motor 50 can be provided by the generator 42, thereby truly achieving the effect of energy saving and environmental protection.

[0049] See also Figure 3 As shown, the cooling water tower with a hydroelectric power generation unit provided in the second embodiment of the present invention is different from the first embodiment in the type of the hydroelectric power generation unit.

[0050] The hydroelectric unit 40 is composed of a shell 41, a generator 42 and a runner blade 44, wherein the shell 41 is arranged in the power generation trough area 112 and adjacent to the partition 12, and has a water inlet portion 411 against the partition 12 and a water outlet portion 412 lower than the water inlet portion 411, the generator 42 has a power generation module 421 and a power generation shaft 422 inserted in the shell 41, the runner blade 44 can be rotatably arranged in situ in the shell 41 and fixed on the power generation shaft 422, when the water in the sump area 111 flows through the partition 12 and flows into the power generation trough area 112, the water will flow into the shell 41 from the water inlet portion 411 and out from the water outlet portion 412, and at the same time drive the runner blade 44 to rotate.

[0051] In particular, when water flows through the shell 41 , the water hits the impeller blades 44 , which is the center point of the tangential force impact, causing the impeller blades 44 to rotate and then drive the generator shaft 422 to rotate, so that the generator 42 generates electricity.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
