Abstract

The invention relates to a nuclear grade cooling tower, comprising a tower body. The tower body comprises at least one air outlet and at least one air inlet, and the inner of the tower body is provided with a fan, a water collector, a water distributor and fillers from top to bottom. The fan is used to generate the circulating air which can exchange heat with water in the water collector, in the water distributor and in the fillers to decrease the temperature in the tower. The tower is characterized in that a baffle of the air outlet is arranged in the tower body between the fan and the air outlet, and the baffle is used to avoid the influence on normal operation of the fan by the objects or strong airflow passing the air outlet. Due to the baffle of the air outlet arranged in the tower body between the fan and the air outlet, the nuclear grade cooling tower has high safety precautions, thereby ensuring the normal operation under the conditions of falling objects and strong airflow impact caused by explosion, and the severe natural conditions such as the tornado and the like.

Description

technical field [0001] The invention relates to a cooling device, in particular to a nuclear-grade cooling tower used for heat dissipation in the final heat sink of a nuclear island of a nuclear power plant. Background technique [0002] Nuclear power is widely recognized around the world as a proven technology capable of delivering large amounts of electricity at base load, reliably and without polluting the air, or emitting greenhouse gases. Hydropower, wind power, and solar power are also environmentally friendly, but they cannot guarantee long-term continuous operation with base load. [0003] The operation of nuclear power plants requires a large amount of cooling water as the final heat sink. The nuclear power units currently in operation and under construction in my country are all located in coastal areas, and are cooled by direct current cooling with seawater. The "ultimate heat sink" becomes inevitable. [0004] At present, mechanical cooling towers used in genera...
