Abstract

The invention discloses a steam generator inclined tube bundle heat exchange experimental device and method. The experimental device comprises an inclined tube bundle, a rectangular sleeve, an inlet diverging section, an outlet converging section, a rectifier, an inlet connector and an outlet connector, wherein the inlet diverging section and the inlet connector are welded at the lower part of therectangular sleeve in turn, the outlet converging section and the outlet connector are sequentially welded on the upper part of the rectangular sleeve, the inclined tube bundle is inserted into the rectangular sleeve obliquely downwards at an angle of 45 degrees from the outside through a reserved through hole, the rectifier is installed at the lower part of the rectangular sleeve, and the experimental device is connected to a whole test pipeline system through the inlet connector and the outlet connector. The experimental device has a simple overall structure, is easy to process, is low in cost, and provides a simulator for studying the flowing and heat transfer characteristics of inclined tube bundles of steam generators. The invention also provides the experimental method of the experimental device. The method can be used to carry out experiments of single-phase water and steam-water two-phase fluid, and test and verify the heat transfer characteristics of the inclined tube bundlesof the steam generators by changing inlet parameters of a working medium.

Description

technical field [0001] The invention relates to the technical field of steam generators in nuclear power plants, in particular to a steam generator inclined tube bundle heat exchange experimental device and method. Background technique [0002] The steam generator is the hub of the primary and secondary loops in the nuclear reactor. It transfers the heat generated by the primary loop to the secondary loop to generate steam to drive the steam turbine to generate electricity. Under normal working conditions, the relatively hot coolant flowing through the core flows out from the outlet nozzle of the pressure vessel, enters the steam generator through the heat pipe section, is cooled by the water on the secondary side in the U-shaped pipe area of ​​the steam generator, and then enters through the transition pipe section The main pump is boosted by the main pump and then injected into the core through the cold pipe section. The water on the secondary side gets the heat transferr...
