Abstract
The invention relates to a natural-ventilation wet-type cooling tower with rain area water kinetic energy recycling function. The cooling tower comprises a cooling tower body, a rain area, a padding area arranged above the rain area, a water kinetic energy recycling impeller group arranged on the rain area and an induced draught fan group arranged on the upper side of the padding area, wherein each water kinetic energy recycling impeller in the water kinetic energy recycling impeller group is connected with a corresponding induced draught fan by virtue of a connecting rod, the rainwater in the water area naturally falls into the water kinetic energy recycling impeller group, the rainwater drives the water kinetic energy recycling impeller group to rotate, and the water kinetic energy recycling impeller group drives the induced draught fan group to rotate by virtue of the connecting rods. Under the driving of the induced draught fans, the air volume of the air inlet of the cooling tower (the ventilation quantity of the cooling tower) is increased, the air successively passes through the rain area and the padding area, and is used for cooling the recycled water. Because the ventilation quantity of the cooling tower is improved, the water temperature of the outlet of the cooling tower is lowered, and the economical efficiency of a power plant is improved.
