Vertical MSR structure of offshore floating reactor

Abstract

The invention discloses a vertical MSR structure of an offshore floating reactor, solves the problem that an existing MSR structure is large in occupied area and not suitable for the offshore floatingreactor, and belongs to the technical field of nuclear power. The vertical MSR structure comprises a vertical shell, a steam-water separation device and a reheater, the steam-water separation deviceand the reheater are arranged in the vertical shell and are sequentially arranged along the vertical shell from bottom to top. The reheater comprises a heat exchange tube bundle, baffle plates, a heating steam inlet connecting tube and a reheater drain outlet connecting tube; and the heating steam inlet connecting tube and the reheater drain outlet connecting tube are arranged on the upper portionand the lower portion of the heat exchange tube bundle respectively and communicated with the heat exchange tube bundle, the plurality of baffle plates are evenly distributed on the periphery of theheat exchange tube bundle, and a circulating steam outlet is formed in the upper portion of the vertical shell. The reheater and the steam-water separation assembly are arranged up and down, the occupied area is small, the vertical MSR structure can be applied to narrow space, and the overall arrangement flexibility of an offshore floating reactor unit is improved. The baffle plates are arranged,countercurrent heat exchange is achieved, and the heat exchange efficiency of the reheater is high.

Description

technical field [0001] The invention relates to a vertical MSR structure applied to offshore floating reactors, belonging to the technical field of nuclear power. Background technique [0002] Nuclear power units must be equipped with a Moisture Separator Reheater (MSR) between the high-pressure cylinder and the medium-low pressure cylinder of the steam turbine. Its function is to remove the moisture in the steam discharged from the high-pressure cylinder and heat the steam. , can reduce the erosion damage and vibration of the blades, thereby improving the safety and economy of nuclear power unit operation. [0003] With the development of the marine industry, offshore floating reactors, as an important tool for upgrading the marine economy and exploring solutions to energy problems, are also developing rapidly. The offshore floating reactor has a small footprint, compact structure, and limited space, which also puts forward more flexible requirements for the design of the ...
