Technical Field

[0001] This utility model relates to facilities in the field of hydropower generation, specifically a cooling tower circulating water reuse, energy-saving and environmentally friendly cooling tower hydropower generation device. Background Technology

[0002] Currently, cooling towers are classified according to their ventilation methods: 1. Natural ventilation cooling towers, such as hyperbolic cooling towers in power plants; 2. Mechanical ventilation cooling towers, such as cooling towers in the chemical and metallurgical industries; and 3. Hybrid cooling towers that combine natural and mechanical ventilation. Cooling towers are like natural reservoirs, with the circulating water circulating day after day, wasting energy and increasing the operating costs of enterprises. Summary of the Invention

[0003] The purpose of this utility model is to provide a cooling tower power generation device that addresses the shortcomings of existing technologies, solves energy waste, reduces energy consumption, creates economic value, and is energy-saving and environmentally friendly.

[0004] A cooling tower power generation device is applied to a natural ventilation cooling tower, a mechanical ventilation cooling tower or a natural ventilation + mechanical ventilation hybrid cooling tower. The device is characterized by including a wind duct, the wind duct being located at the top of the cooling tower, a water and air exchange layer (6) being provided below the wind duct, a guide plate (7) being installed on the water and air exchange layer (6) or a water collection pool (10), and a hydroelectric power generation device (9) being provided on the water and air exchange layer (6) or a water collection pool (10).

[0005] The technical solution of this utility model is to modify the existing cooling tower structure. A guide plate is installed at a suitable position in the water-air exchange layer, which is similar to a rainstorm layer in extreme weather. This allows water droplets to concentrate and gather to form a water flow. The guide plate can delay the contact time between the water flow and the air, and also dissipate heat and cool down the water. The water flow impacts the water turbine to rotate, and the water turbine drives the generator to generate electricity. Secondly, a guide plate is installed in the water collection pool to concentrate and gather the water flow, forming a water flow similar to a flash flood on a rainy day. The water flow moves violently in the water collection pool, increasing the contact time with the air and cooling down the water. It can also impact the water turbine to rotate, and the water turbine drives the generator to generate electricity.

[0009] The following description, in conjunction with the accompanying drawings, further illustrates a cooling tower power generation device of this utility model. The drawings are schematic diagrams of a mechanical ventilation cooling tower structure. The technical solution of this utility model is a modification based on the existing cooling tower structure. The air duct (1) is located at the top of the cooling tower. The ventilation equipment (5) is installed on the air duct (1) to draw out the hot air generated by the exchange of water and air below. The water collection device (2) filters the water droplets generated by the exchange of rising water and air. The water return diversion system evenly sprays the hot water used in the production workshop to fully contact the air for cooling. The water spraying device evenly distributes water, increases the contact area, prolongs the contact time, and improves the cooling efficiency. The air exchange layer (6) facilitates heat exchange between water and air. The guide plate (7) delays heat dissipation and cooling while simultaneously causing water droplets to accumulate and form a water flow. The water flow impacts the impeller of the hydroelectric generator (9), causing it to rotate. The rotation of the impeller drives the generator to rotate via a transmission device, generating electricity. The hydroelectric generator (9) is connected to the enterprise's power grid and controlled by the enterprise's electrical system. The support (8) supports the guide plate (7). The guide plate (7) is like a shed for building a house, and the support (8) is like the pillars for building a house. The guide plate (7) can be designed as a single layer or multiple layers depending on the size, structure, and environmental conditions of the cooling tower. The water collection pool (10) collects the return water. The diversion system (3) consists of all the cooling water, makeup water, and water treatment components sprayed down. The return water is pumped back to the production workshop for recycling via a conveying device pump station. Secondly, a guide plate (7) is installed in the collection pool (10) to divide the collection pool (10) into narrow spaces so that the water flow is concentrated and forms a flow like a flash flood on a rainy day. The water flow moves violently in the collection pool, increasing the contact time with the air and cooling down. A hydroelectric generator (9) is installed at a suitable position on the collection pool (10) so that the water flow can impact the turbine to rotate, and the turbine can drive the generator to rotate and generate electricity. Depending on the scale of the cooling tower and environmental conditions, one or more hydroelectric generators can be installed. Place (9), bracket (8) in the water collection pool (10) to support and stabilize the guide plate (7), there are various types, sizes and working conditions of hydroelectric generators on shopping platforms such as Taobao and JD.com, and can also be designed and manufactured by oneself. A cooling tower power generation device is applied to natural ventilation cooling tower, mechanical ventilation cooling tower or natural ventilation + mechanical ventilation mixed cooling tower. It is characterized by including a wind duct, the wind duct is located at the top of the cooling tower, a water and air exchange layer (6) is set below the wind duct, a guide plate (7) is installed on the water and air exchange layer (6) or the water collection pool (10) has a hydroelectric power generation device (9).
