Problems solved by technology

The direct air-cooling system is greatly affected by the external environment, mainly affected by the wind speed and wind direction. It is expected that there will be hidden dangers of sudden deterioration of the vacuum that will cause the generator set to shed load or even trip.

Abstract

The invention discloses a novel indirect type air cooling device for a nuclear power plant. The indirect type air cooling device sequentially comprises a wind power generation device, a draining tower, an induced draft fan, a cooler and a cooler support. The wind power generation device is connected with the draining tower through a draft fan support, the induced draft fan is arranged between the draining tower and the cooler, the cooler comprises a circulating water pipeline, and a set of louver blade grids are arranged on the periphery of the circulating water pipeline. According to the novel indirect type air cooling device for the nuclear power plant, moisturizing-free of circulating cooling water is achieved, the water consumption for daily operation of the nuclear power plant is greatly reduced, and a technological possibility is provided for cold source establishment of the nuclear power plant in a water shortage area. Wind speed influences and wind direction influences on cooling operation working conditions of the indirect type air cooling device are small, and long-term safe and stable operation of the nuclear power plant is facilitated.

Description

technical field [0001] The invention belongs to the field of energy, and in particular relates to a novel indirect air cooling device of a nuclear power plant. Background technique [0002] my country is a country with poor water resources, and nuclear power plants consume a lot of water, and the largest water consumption is circulating cooling water. At present, the nuclear power plants that have been built in China are all located in coastal areas, and all adopt seawater direct current cooling method, and there is no limit. With the continuous construction of nuclear power plants, it will become possible to build nuclear power plants in areas with severe water shortages. However, one of the most prominent problems currently restricting the construction of nuclear power plants in severe water shortage areas is what kind of circulating water cooling system to use to meet the safe and stable operation requirements of nuclear power plants under the severe conditions in t...
