Abstract

The invention discloses a corrugated plate assembly for a dryer of an ACP1000 nuclear power vapor generator. The corrugated plate assembly comprises a base plate, water blocking components and supporting components, wherein the water blocking components and the supporting components are positioned on the base plate. Corrugated corrugations are formed on the base plate, the water blocking components are arranged at the positions of the crests of the front and / or the rear of the base plate or the tail end flat section of the base plate, and the supporting components are arranged at the positions of the flat sections of the two tail ends of the rear of the base plate. The corrugated plate assembly for the dryer of the ACP1000 nuclear power vapor generator is of a double-hook corrugated plate mode with a distance frame or a distance block, selective optimization is performed on the shape, structure and dimension of the base plate corrugations, the water blocking components and the supporting components, the corrugated plate assembly has high steam-water separation efficiency and low flow resistance so as to be suitable for the dryer of the ACP1000 nuclear power vapor generator, and the water content of steam processed through the corrugated plate assembly can be as low as about 0.1%. The corrugated plate assembly is simple in structure, rational in design, convenient to install, easy to manufacture and low in cost.

Description

technical field [0001] The invention relates to steam drying and steam-water separation technology in the field of nuclear power, in particular to a corrugated plate assembly for an ACP1000 nuclear power steam generator drier. Background technique [0002] The nuclear power steam generator is one of the three major devices in the nuclear island. It transfers the heat generated by the nuclear reactor to the secondary side of the steam generator. The steam generated is dried by the primary and secondary steam-water separation devices and drives the turbogenerator to generate electricity. The dried steam needs to meet the requirement that the humidity is less than 0.25%. [0003] Among them, the first-stage steam-water separation device mostly adopts a swirling vane separator, and its steam-water separation efficiency is about 90%; The steam circulation channel is formed, and the wet steam changes the flow direction many times in the curved channel, and the fine water droplets...
