Description

Cooling tower with hydroelectric power generation unit

The present invention relates to a cooling water tower, and in particular to a cooling water tower with a hydroelectric power generation unit.

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

Cooling water tower structure: The water to be cooled is sprayed downward through the pipe at the top of the water tower. In addition, there is a blower on the wall of the water tower to blow air in, and there is a large exhaust fan on the top to extract air out of the top of the tower, which is conducive to air flow and accelerates the cooling of water. There are zigzag hollow PVC heat sinks above and below the spray pipe to increase the heat dissipation time of water droplets. The design is in this shape because the hyperbolic shape is conducive to convection heat exchange between water and air.

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 the Republic of 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.

The purpose of the present invention is to provide a cooling water tower with a hydraulic power generation unit.

To achieve the above-mentioned purpose, the present invention is a cooling water tower with a hydraulic power generation unit, comprising: a water tower body having a water collecting tank, the water collecting tank having a partition to form a water collecting tank area and a power generation tank area adjacent to the water collecting tank area; a sprinkler disposed in the water tower body and located above the water collecting tank area; a water guide plate disposed in the water tower body and located between the water collecting tank and the sprinkler, It has a water guide corresponding to the sprinkler, and a water outlet connected to the water guide and located above the water collection tank area; and a hydraulic power generation unit, which is arranged in the power generation tank area of the water tower body and adjacent to the partition. When the water in the water collection tank area flows through the partition and flows into the power generation tank area, the water flows through the hydraulic power generation unit, and the hydraulic power generation unit generates electricity by the height difference of the water.

The effect of the present invention is that the water collecting tank of the water tower body is separated into a water collecting tank area and a power generating tank area, and the sprinkler, water guide plate and hydraulic power generating unit are designed so that 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 and flow into the power generating tank area. At this time, the water flowing into the power generating tank area will flow through the hydraulic power generating unit, and the hydraulic power generating unit generates electricity by the height difference of the water. Based on this, the present invention can directly convert the cooling water of the cooling water tower that has been cooled down 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.

Preferably, the hydraulic power generation unit includes a housing, a generator and a spiral blade. The housing is disposed in the power generation trough area and abuts against the partition, and has a water inlet and a water outlet lower than the water inlet. The generator has a power generation module and a power generation shaft inserted in the housing. The spiral blade is rotatably disposed in the housing and fixed to the power generation shaft. When the water in the water collection trough area flows through the partition and flows into the power generation trough area, the water will flow into the housing from the water inlet and out from the water outlet, and at the same time drive the spiral blade to rotate.

Preferably, the hydroelectric generating unit includes a housing, a generator and a rotor blade.

The operation mode and effect of the present invention are as follows: when the sprinkler 20 sprays the water to be cooled (as shown by the arrow in Figure 2) downward, 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 to allow the water to flow 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.
