Description

Technical Field

[0001] The invention relates to the technical field of power generation, and in particular to a cooling tower waste water power generation device. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses water and air flow to exchange heat and generate steam. The steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer, and radiation heat transfer. It is an evaporative heat dissipation device that dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature to ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower. Cooling towers are divided into open cooling towers and closed cooling towers according to whether water and air are in direct contact. A return water tank is generally provided below the open cooling tower. In addition to being directly supplied to the production workshop, a portion of the return water from the cooling tower is directly returned to the return water tank. How to use the residual water in the return water tank to generate electricity while reducing the modification of the cooling tower pipeline has become a difficult problem that needs to be solved urgently by technicians in this field.

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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.

[0022] like Figure 1-3 As shown, a cooling tower waste water power generation device includes a water collecting component 1 and a hydro-turbine generator 2. The hydro-turbine generator 2 is installed on the water collecting component 1. The water collecting component 1 is placed in a return water tank below the cooling tower. The return water in the cooling tower flows into the return water tank after passing through the water collecting component 1 and the hydro-turbine generator 2 in sequence.

[0023] Specifically, the water collection assembly 1 includes a mounting plate 12, a water tank 11 is mounted on one side of the mounting plate 12, the hydro-generator 2 is mounted on the other side, and a support rod 13 is mounted on the bottom of the mounting plate 12; a water outlet hole is opened on the side wall of the water tank 11, and the water inlet of the hydro-generator 2 and the water outlet hole on the side wall of the water tank 11 are connected by a pipe.

[0024] Specifically, a float switch 14 is placed inside the water tank 11, and a controller 15 is also installed on the mounting plate 12. An electric valve is provided on the pipeline between the water inlet of the hydro-generator 2 and the water outlet of the side wall of the water tank 11, and the electric valve and the float switch 14 are both electrically connected to the controller 15.

[0025] Specifically, the hydro-generators 2 are provided in plurality and are evenly distributed on the mounting plate 12 .

[0026] Specifically, the length of the support rod 13 is greater than the height of the return pool.

[0027] Specifically, an inclined baffle plate 16 is installed on the side wall of the water tank 11 , and the baffle plate 16 is located directly above the mounting plate 12 .

[0028] Specifically, the water collection components 1 are provided in plurality and arranged in an array in the water return pool, and the water tanks 11 of every two adjacent water collection components 1 are connected by a pipeline.

[0029] Specifically, the hydro-turbine generator used in the present invention is a horizontal hydro-turbine generator.

[0030] The use process of the present invention is as follows:

[0031] First, multiple hydro-turbine generators 2 are installed on the mounting plate 12, and the hydro-turbine generators and the water tank 11 are connected together through pipes. Then, the water collection component 1 installed with the hydro-turbine generators 2 is placed in the return water tank. Finally, the above operation is repeated to place an array of multiple water collection components 1 installed with the hydro-turbine generators 2 in the return water tank.

[0032] The residual water falling from the cooling tower into the return water tank is first collected by the water collecting component 1, and then the collected residual water in the water tank 11 in the water collecting component 1 flows into the hydro-generator 2 through a pipeline, driving the hydro-generator 2 to generate electricity, and finally, the residual water flows from the hydro-generator 2 to the return water tank.

[0033] In order to increase the impact force of water flow, a float switch 14 is arranged in the water tank 11, a controller 15 is arranged on the mounting plate 12, and an electric valve is arranged on the connecting pipe between the water tank 11 and the hydro-turbine generator 2. When the remaining water in the water tank 11 is collected to a preset water level, the float switch 14 sends a signal to the controller 15. After the controller 15 receives the signal, the controller's electric valve opens, and the remaining water in the water tank 11 flows to the hydro-turbine generator through the pipe.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
