Description

Technical Field

[0001] This invention belongs to the field of cooling tower technology, and in particular relates to an energy-saving and environmentally friendly mechanical ventilation cooling tower. Background Technology

[0002] In current mechanical ventilation cooling tower equipment, after the cooling air cools the medium, a large amount of cooling air is discharged into the air, forming white mist at the cooling tower outlet. This cooling air has a high wind speed and pressure (9.31 m / s, pressure 35.13 Pa) and contains high kinetic energy and a large amount of moisture. Currently, there is no solution or equipment to utilize, convert, or store this kinetic energy, nor is there any solution or equipment to recover the moisture. The only solution is to discharge and release it, resulting in a significant waste of energy and water resources. Summary of the Invention

[0013] To make the objectives, technical solutions, and advantages of this invention clearer, the following detailed embodiments are described in conjunction with the appendix. Figs. 1-3 The present invention will be described in further detail below. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0014] This invention provides an energy-saving and environmentally friendly mechanical ventilation cooling tower. The cooling tower is equipped with an exhaust assembly. At the lower end of the exhaust assembly, a heat dissipation assembly 9 and a cooling tower water tank 10 are arranged in sequence. A cooling air inlet 11 is provided between the cooling tower water tank 10 and the heat dissipation assembly 9. At the upper end of the exhaust assembly, a power generation assembly is provided. The power generation assembly includes rotatably arranged porous fiber bundle blades 4. The rotation of the porous fiber bundle blades 4 drives the wind power generator 1 to rotate and generate electricity. The electrical energy generated by the wind power generator 1 is transmitted to the control inverter unit 13 through a cable connected to the junction box 2.

[0015] The airflow driven by the exhaust assembly rotates the porous fiber bundle blades 12, converting the exhaust kinetic energy into electrical energy via a wind turbine. This electrical energy can be used to power the cooling tower itself or external equipment, reducing dependence on the external power grid and lowering operating costs. The power generation component is integrated into the upper part of the cooling tower, requiring no additional ground space, making it suitable for installation in industrial sites or densely built-up areas. In use, the cooling tower fan motor is started, driving the exhaust assembly. The airflow inside the cooling tower shroud 6 rises, driving the porous fiber bundle blades 4 to rotate. The rotation of the porous fiber bundle blades 4 drives the wind turbine 1 to generate electricity. The electrical energy is transmitted to the control inverter unit 13 through the junction box 2 and cables, where it is processed and used by the cooling tower or external equipment.

[0016] Preferably, the porous fiber bundle blade 4 is provided with a porous fiber bundle assembly, which is made of porous material and is used to adsorb water vapor in the cooling air; the porous fiber bundle assembly is connected to a condensation unit, which condenses the adsorbed water vapor into liquid water through natural cooling or active cooling; the surface of the porous fiber bundle assembly is provided with a flow guide and a water collector, and the water collector is connected to an external water pool through a condensate pipe 14.

[0017] The porous fiber bundle assembly adsorbs water vapor from the cooling air and converts it into liquid water through the condensation unit, reducing water loss. This is especially suitable for water-scarce areas or water-intensive industries. The porous fiber bundle blades simultaneously achieve "wind power generation" and "water vapor recovery," enhancing the equipment's versatility and reducing investment costs. In operation, cooling air enters the cooling tower through the cooling air inlet, exchanges heat with the heat dissipation components, and then carries water vapor upwards. The porous fiber bundle assembly adsorbs the water vapor, and the condensation unit condenses the water vapor into water through natural or active cooling. The condensate flows along the guide pipe into the water collector and is then transported to an external water tank for recycling via the condensate pipe.

[0018] Preferably, the power generation component includes a support frame 5 installed on the upper part of the cooling tower. The support frame 5 and the air collection shroud 3 adopt a modular design, which facilitates assembly, disassembly, and maintenance, reducing subsequent operation and maintenance costs. The support frame 5 is equipped with an air collection shroud 3 that connects to the cooling tower shroud 6. The air collection shroud 3 and the cooling tower shroud 6 are seamlessly connected, maximizing the collection of rising airflow, improving blade rotation efficiency, and increasing power generation. The porous fiber bundle blades 12 are rotatably disposed within the air collection shroud 6. The power generation component can be directly installed on the upper part of an existing cooling tower without changing the original structure, realizing the conversion of kinetic energy into electrical energy.

[0019] Preferably, the heat dissipation component 9 includes a plurality of evenly arranged heat dissipation fins, the upper end of the heat dissipation fins is provided with a hot water pipe 7, the hot water pipe 7 is provided with a plurality of hot water pipe nozzles 8, and the hot water pipe nozzles 8 spray hot water onto the heat dissipation fins 9.

[0020] Preferably, the heat sink is S-shaped. The S-shaped heat sink increases the contact area between the hot water and the air, and the hot water pipe nozzle sprays hot water evenly, enhancing the heat exchange effect and reducing the outlet water temperature.

[0021] Preferably, the exhaust assembly includes cooling tower fan blades 12 within the cooling tower shroud 6. The edges of the cooling tower fan blades 12 are spaced apart from the inner wall of the cooling tower shroud 6. The cooling tower fan blades 12 rotate under the action of the cooling tower fan motor. The gap design between the cooling tower fan blades 12 and the inner wall of the shroud reduces airflow friction loss, improves ventilation efficiency, and reduces fan energy consumption. The cooling tower fan blades 12 are connected to the cooling tower fan motor.

[0022] During operation, the cooling tower fan motor is turned on, driving the cooling fan blades to rotate. The blades are installed at a specific angle, generating upward thrust as they rotate, pushing the air inside the tower upwards. Because the gap between the cooling tower shroud and the blades is less than 5mm, a negative pressure zone is formed below the blades, causing external cooling air to be continuously drawn into the tower from the air inlet, flowing upwards through the heat sink assembly. At this time, hot water is evenly sprayed onto the S-shaped heat sink through hot water nozzles, forming convective heat exchange with the cooling air. The cooled water falls into the cooling tower water tank for recycling.

[0023] Hot air carrying a large amount of water vapor continues to rise (its high humidity content makes it appear white, forming water mist at the outlet). Under the thrust of the fan blades, the wind speed increases to 10-35 m / s and the pressure reaches 15-79 Pa. This high-energy airflow propels the blades with porous fiber bundles to rotate. During rotation, the porous fiber bundles collect water vapor from the cooling air, converting it into liquid water through a condensation unit. The liquid water flows along a duct to a water collector, and then through a condensate pipe to an external water tank, achieving water resource recovery while preventing the cooling tower outlet from becoming foggy, thus meeting environmental protection requirements.

[0024] The rotating blades with porous fiber bundles drive the wind turbine to generate electricity, which is then transmitted to the control inverter unit via a junction box and cables. Since the generator output frequency is below 45Hz and the voltage is 13-25V, the control inverter unit needs to regulate the frequency and voltage to obtain stable 50Hz, 380 / 220V power, which is then safely delivered to users. The remaining power is stored in an energy storage device for use during peak electricity demand.

[0025] This invention requires no modification to existing cooling towers, has a simple structure, is easy to install, and can reduce energy consumption through wind energy recovery and reduce water resource loss, resulting in significant economic benefits.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
