Description

Technical Field

[0001] The present invention relates to a steam-water separation device, belonging to the technical field of pressure vessels. Background Art

[0002] A steam generator is one of the key main equipment in a pressurized water reactor nuclear power plant. It is the pressure boundary between the primary side and the secondary side, and is used to transfer the heat of the primary side reactor coolant to the secondary side through heat transfer tubes, heating the secondary side water into saturated steam. The wet steam is separated by a steam-water separator and a dryer. The qualified steam after separation drives the steam turbine to do work and generate electricity. The steam-water separator is an important part of the steam generator. The wet steam generated by the steam generator tube bundle is initially separated by the steam-water separator to remove most of the water in the wet steam. The steam coming out of the steam-water separator enters the dryer for further separation. The main function of the steam-water separator is to reduce the steam humidity at the dryer inlet and create conditions for generating qualified steam by the steam generator.

[0003] In the existing steam generators, the steam-water separator usually uses wire meshes for filtration. After being used for a period of time, the wire meshes will become blocked and need to be maintained. However, the existing steam-water separator has a complex structure, and the disassembly and assembly are very inconvenient, which is not conducive to the later maintenance and replacement of the wire meshes.
