Automatic suction-off device of nuclear power station circulating water filtering system

Abstract

The invention discloses an automatic suction-off device of a nuclear power station circulating water filtering system. The automatic suction-off device comprises a connector, a suction-off pump, a suction-off pipeline and a collecting pipe ditch, wherein the suction-off pump is connected to the lower portion of the suction-off platform in a lifting mode and connected to a collecting net of the circulating water filtering system through the connector, and seawater and garbage on the collecting net are sucked in, the collecting pipe ditch is arranged on the suction-off platform, the first end of the suction-off pipeline is connected to the suction-off pump, the second end of the suction-off pipeline extends to the suction-off platform and faces the collecting pipe ditch, and the seawater and garbage pumped by the suction-off pump are conveyed into the collecting pipe ditch through the suction-off pipeline. According to the automatic suction-off device of the nuclear power station circulating water filtering system, sundries intercepted on the collecting net are sucked and collected in a suction-off mode, manual intervention does not need, the height of the suction-off pump for suction can be adjusted, up-and-down movement adjustment along with the tide level is achieved, and the device is suitable for the used environment of a large-tide-range factory site.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to an automatic suction device for a circulating water filtering system of a nuclear power plant. Background technique [0002] In order to deal with the increasingly serious outages caused by marine organisms invading the cooling water system of nuclear power plants, the current method is to set up a collection net at the seawater inlet to intercept and collect the organisms and solids in the incoming seawater. Moreover, it mainly relies on manual cleaning of the collection net. When the amount of debris collected in it is large, the entire collection net is directly replaced; when the amount of debris is small, it is manually dumped into the debris basket of the operation and maintenance ship. [0003] There are mainly following defects in the above-mentioned method at present: [0004] (1) Relying on manpower, the labor intensity is extremely high, and it is impossible to ...

AI Technical Summary

Problems solved by technology

[0004] (1) Relying on manpower, the labor intensity is extremely high, and it is impossible to work under severe weather conditions. In severe cases, due to the debris not being cleaned up in time, the net bag may rupture, and the entire pre-filtration system of the nuclear power plant will fail.

[0005] (2) Water surface operations are required, and the cooperation of ships, occupational safety risks are relatively high, and work efficiency is low
