Abstract

The invention relates to a photovoltaic power generation and mechanical draft cooling tower combined energy-saving and efficiency-improving method and device. The method comprises the following steps: a solar cell panel is mounted above an air inlet region of an air inlet of a mechanical draft cooling tower, and shading and cooling are carried out on the air inlet region through the solar cell panel, the mounting height of the solar cell panel is determined according to the field condition and the mounting inclination angle and is not higher than an air duct of the mechanical draft cooling tower; a spray cooling device is installed in the space from the back face of the solar cell panel to the air inlet lower edge of the air inlet, and the spray amount of the spray cooling device is determined according to the environment humidity and/or the air amount of the mechanical draft cooling tower; and an automatic control device controls a water supply device to pressurize and filter circulating water in the mechanical draft cooling tower and then supply the circulating water to the spray cooling device. By means of the arrangement, the technical problems that due to the fact that an existing mechanical draft cooling tower is high in outlet water temperature in summer, equipment using cooling water is high in operation energy consumption, distributed photovoltaic power generation cost is high, and economic benefits are low can be solved.

Description

Technical field[0001]The present application relates to the field of mechanical ventilation cooling tower and photovoltaic power generation technology, and more particularly to an energy saving and efficiency method and apparatus for photovoltaic power generation and mechanical ventilation cooling tower.Background technique[0002]The existing mechanical ventilation cooling tower is water as a circulating coolant, and the water flows into contact with air and the absorbed heat is discharged to the atmosphere to reduce the water temperature. The mechanical ventilation cooling tower is generally inadequate in summer cooling, and the water temperature is high. The main reason is that the environment is elevated, the humidity is increased; the mechanical ventilation cooling tower is long-term operation, the dispersion coefficient of the filler decreases, resulting in water and air contact The area is reduced; damage is damaged, blocked phenomenon, increase the resistance in the tower, and...
