Embodiment Construction

[0019] A thermal state test system for steam-water separation performance based on a closed steam cycle proposed by the present invention will be further described in detail below with reference to the accompanying drawings and specific examples. Advantages and features of the present invention will be apparent from the following description and claims.

[0020] see figure 1 , In one embodiment, a thermal test system for steam-water separation performance based on a steam closed cycle, including a saturated water circulation loop, a steam circulation loop, and a test vessel body system.

[0021] The saturated water circulation loop includes a first pipeline, a main circulation pump 1 , an electric control valve 5 for the main pipeline, and a first flow meter 2 arranged on the first pipeline. The input end of the first pipeline communicates with the water outlet of the test container body system, and the output end of the first pipeline communicates with the water input end of...

Abstract

The invention discloses a steam-water separation performance thermal state test system based on steam closed cycle. A test container body system comprising a pressure container, an electric heater, asteam-water mixer and other elements is arranged, and the test container body system comprises a saturated water circulation loop comprising a first pipeline, a main circulation pump, a main pipelineelectric control valve and a first flow meter, a steam circulation loop comprising a second pipeline, a steam compressor, a steam dryer, a steam outlet electric control valve and a second flow meter.The saturated water circulation loop and the steam circulation loop are arranged on a test container body system, so that water circulation and steam circulation are realized. The electric heater heats water at the bottom of the pressure container, hot water and steam circulate through the saturated water circulation loop and the steam circulation loop respectively, and the generated high-temperature and high-pressure steam-water mixture reaches the real working condition. An electric heater and two sets of matched circulation loops are adopted, and the problems that an existing test system device is complex, and the real operation condition cannot be simulated are solved.

Description

technical field [0001] The invention belongs to the technical field of steam-water separation performance thermal state test, in particular to a steam-water separation performance thermal state test system based on steam closed cycle. Background technique [0002] High-quality steam is one of the important conditions to ensure the safe and economical operation of nuclear power plants. The steam-water separation device is a key component of the steam generator of the main equipment of the nuclear power plant. Its function is to separate the steam-water mixture in the steam generator into two phases. It not only directly determines the quality of the steam supplied to the secondary circuit steam turbine, but also has a very high separation efficiency. largely determines the size of the steam generator and the pressure drop on the secondary side. Only a properly designed steam-water separation device can meet the requirements of saturated steam humidity at the outlet of the st...
