Abstract

This application relates to the technical field of nuclear power plant steam systems, and provides a steam-water separation reheater system for nuclear power plants, including a steam-water separation reheater, a drain tank, a transmission device, and a display column. The steam-water separation reheater is connected to the drain tank through a condensate pipe. The display column is connected to the drain tank through the transmission device. The steam-water separation reheater is used to connect the exhaust steam of the high-pressure cylinder for dehumidification and heating. The drain tank is used to receive the water generated during the operation of the steam-water separation reheater through the condensate pipe. The transmission device It is used to transmit the liquid in the drain tank to the display column, and cool the liquid during the transmission process, and the display column is used to display the liquid level in the drain tank. In the steam-water separation reheater system of the above-mentioned nuclear power plant, the drain box can prevent condensed water from affecting the working performance of the steam-water separation reheater, and the transmission device can reduce the temperature of the liquid in the drain tank and display column, reduce the flashing range, and make the liquid level fluctuation small , reducing the number of unplanned downtime and improving reliability.

Description

technical field [0001] The present application relates to the technical field of nuclear power plant steam systems, and in particular, to a nuclear power plant steam-water separation reheater system. Background technique [0002] When the turbo-generator is working, the steam generated by the nuclear island steam generator expands in the high-pressure cylinder, and the thermal energy is converted into mechanical energy, which makes the blades rotate to drive the generator to generate electricity. The steam expands step by step in the high-pressure cylinder to do work, the pressure and temperature of the steam gradually decrease, and the humidity of the exhaust steam leaving the last-stage blade of the high-pressure cylinder is high. In order to improve the working conditions of the low-pressure cylinder, a steam-water separation reheater is usually installed. After the exhaust steam of the high-pressure cylinder enters the steam-water separation and reheater, it first passes...
