Steam-water separator and steam generator simulation body

Abstract

The invention discloses a steam-water separator. The steam-water separator is formed by the lower cone section (1), the ascending cylinder lower section (2), the upper cone section (3) and the ascending cylinder upper section (4); the lower cone section (1) and the upper cone section (3) are of structures with wide lower portions and narrow upper portions; the upper end of the lower cone section (1) is connected with the lower end of the ascending cylinder lower section (2); the upper end of the ascending cylinder lower section (2) is connected with the lower end of the upper cone section (3); the upper end of the upper cone section (3) is connected with the lower end of the ascending cylinder upper section (4). The invention also discloses a steam generator simulation body. According to the steam-water separator and the steam generator simulation body, rotating blades and a dryer are omitted under the condition that the test requirements are met and accordingly the structure is simple and the cost is low.

Description

technical field [0001] The patent of the invention relates to the fields of nuclear industry, thermal power generation and petrochemical industry, in particular to a steam-water separator and a steam generator simulation body. . Background technique [0002] At present, the vertical natural circulation steam generators used in pressurized water reactors mainly include two-stage steam-water separators. After leaving the heat transfer tube bundle, the steam-water mixture first enters the first-stage steam-water separator (rotary vane separator) through the ascending section to remove most of the water, and then enters the second-stage steam-water separator (herringbone plate dryer) for further dehumidification . [0003] The steam separator is an important part of the natural circulation steam generator. The steam-water separator mainly affects the steam quality, and plays an extremely important role in the safe and economical operation of the steam turbine. The structure ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome the disadvantages of the existing steam-water separator with complex structure, large resistance coefficient, large pressure drop loss when the medium flows through, and the inability to meet the requirements of the passive waste heat discharge experiment on the secondary side of the ACP1000. The steam-water separator meets the requirements of the passive waste heat discharge experiment on the secondary side, has a small resistance coefficient, and has a simple structure. At the same time, the steam-water separator can also be applied to other equipment or devices with a low flow rate of the steam-water mixture medium (less than 4m / s).
