Description

Technical Field

[0001] The utility model belongs to the technical field of nuclear power plant filtering equipment, in particular to a nuclear power plant pollution interception system with a pollution interception mechanism. Background Art

[0002] The cooling system of a nuclear power plant usually introduces seawater as a cooling source. Seawater enters the nuclear power plant through the water inlet. In order to filter the seawater and intercept the solid matter in it, a seawater interception net is usually installed at the water inlet. Under long-term operation, domestic and fishery garbage in the ocean, such as plastic bags and fishing nets, will be entangled and attached to the interception net, which will then breed marine organisms, accumulate silt, and block the grille, resulting in a reduction in the cooling seawater inlet area, which in turn causes insufficient cooling sources in the nuclear power plant. At present, the means of interception and pollution removal basically adopt the form of interception by interception nets and manual regular cleaning. When the weather is less windy and waves, a special person will drive a boat to salvage the dirt in the net to the cabin. However, since seawater pollution is difficult to predict and is affected by weather, ocean currents, human activities, etc., there may be an explosive growth of dirt in the open water intake channel. If the ship cannot be launched in bad weather, the dirt will not be cleaned in time. Utility Model Content
