Support spacer block for pressurized water reactor steam generator dryer

Abstract

The invention provides a support spacer block for a double hook waveform plate of a pressurized water reactor steam generator dryer, and can meet the design requirements of the steam generator dryers. A support spacer block is used for separation of every two waveform plates of the dryer; the support spacer block has a corrugated curved shape matching that of the waveform plate; the peak of the corrugated curve of the support spacer block is provided with a groove; the top of the support spacer block is provided with a top end extending outwardly; and the left and right sides of the bottom of the support spacer block are provided with one stand bar extending outwardly respectively. The support spacer block for the double hook waveform plate of the pressurized water reactor steam generator dryer has small size and good support and hydrophobic properties to ensure that the spacing between the waveform plates achieves the desired value, so that the degree of compression of the waveform plates meets the requirements, and little influence is exerted on flow field inside the dryer. The groove arranged on the middle can help water drainage, so as to satisfy the design requirement of the steam generator dryer.

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 support spacer 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 support spacer is an important part of the steam generator dryer. It can make the corrugated plates in the dryer press and position each other, so that the distance between the plates can reach the required value, so that the separation effect can meet the design requirements.

AI Technical Summary

Problems solved by technology

[0004] The unreasonable design of the supporting spacer structure of the dryer in the steam generator will affect the performance of the dryer, so that the steam-water separation effect cannot reach the expected effect, or the plate is not compacted enough to cause flow-induced vibration or vibration
