Embodiment Construction

[0016] A double-hook corrugated plate for a pressurized water reactor steam generator dryer according to the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as figure 1 As shown, a double-hook corrugated plate for a pressurized water reactor steam generator dryer according to the present invention mainly includes a corrugated plate 1 and several water retaining hooks 2 .

[0018] The wave plate 1 has 6 waves, that is, the wave plate 1 has 6 peaks and 6 valleys.

[0019] A water retaining hook 2 is respectively connected to the inner and outer surfaces of each peak and trough of the corrugated plate 1 by means of resistance welding.

[0020] A tail water retaining hook 3 is also provided at the tail end of the corrugated plate 1 . The water retaining hook 3 at the tail is integrally formed with the corrugated plate 1 , that is, the tail end of the corrugated plate 1 is bent to form a hook-...

Abstract

The invention provides a double hook waveform plate for a pressurized water reactor steam generator dryer, and can meet the design requirements of the steam generators. The a double hook waveform plate includes one waveform plate with a plurality of waveforms; the inner and outer surfaces of each peak of the waveform plate are respectively connected to a water retaining hook; the inner surface and outer surface of each trough on the waveform plate are respectively connected to a water retaining hook; and the rear end of the waveform plate is provided with one rear water retaining hook. The double hook waveform plate of the invention has high water-steam separation efficiency, steam with humidity about 20% enters the dryer double hook waveform plate for further separation, and dry steam with humidity of no more than 0.25% is obtained, so as to the meet the design requirements of steam generators. The double hook waveform plate has larger wetted area and more effective water droplets capture than the existing structures, so the separation effect is better.

Description

technical field [0001] The invention relates to the technical field of design of a pressurized water reactor steam generator drier, in particular to a double-hook corrugated plate technology for a pressurized water reactor steam generator drier. Background technique [0002] The steam generator is the heat exchange equipment between the primary and secondary circuits of the pressurized water reactor nuclear power plant. It is used to transfer the heat of the reactor coolant to the secondary side, so that the water on the secondary side becomes steam, and the steam passes through the primary separator and After the dryer, the steam turbine is driven to generate electricity after leaving the steam generator. [0003] The corrugated plate is the core component of the steam generator dryer. Under the action of centrifugal force, inertial force and adhesion force of the wet steam, the water droplets in the steam adhere to the corrugated plate and form a water film, and the water ...
