Marine pressurized water reactor circulating water system with flow rate control function, and flow rate control method thereof

Abstract

The invention relates to a marine pressurized water reactor circulating water system with flow rate control function, and a flow rate control method thereof. The system comprises: a condenser and a circulating water pump connected to the condenser; a vacuum pressure transmitter and a temperature transmitter, wherein the vacuum pressure transmitter and the temperature transmitter are arranged in the condenser, the vacuum pressure transmitter is used for detecting the vacuum pressure of the condenser, and the temperature transmitter is used for detecting a condenser seawater side inlet temperature and a condenser condensed water outlet temperature; a frequency conversion speed regulating device, wherein the frequency conversion speed regulating device at least comprises a signal input end and a signal output end, and the signal output end is connected to the circulating water pump; and a controller, wherein the controller comprises a plurality of signal input and output ports, the vacuumpressure transmitter and the temperature transmitter are respectively connected to the signal input ports of the controller, and the signal input end of the frequency conversion speed regulating device is connected to the signal output port of the controller. According to the present invention, with the system and the method, the flow rate of the circulating water in the condenser can be controlled, and the vacuum pressure and the supercooling degree of the condenser can be adaptively controlled within a set range.

Description

technical field [0001] The invention relates to a pressurized water reactor circulating water system, in particular to a marine pressurized water reactor circulating water system with a flow control function and a flow control method thereof. Background technique [0002] With the development of society, people are no longer satisfied with the development of resources on land, and began to exploit marine resources. However, the exploitation of offshore resources, the development of islands, the living of people, and the improvement of the environment all require a continuous supply of energy. [0003] As an emerging energy carrier on the ocean, ships equipped with small pressurized water reactors can provide energy supply for offshore oil exploitation and island development. In addition to fixed-point energy supply at sea, it can also be used for high-power ship energy supply and seawater desalination water supply, which is of great significance to the development of marine...

Problems solved by technology

[0004] Compared with the land environment, the marine environment is harsher, and the power consumption of ships is tight. At the same time, due to the limitation of cabin layout, there are many restrictions on backup energy and few types. At the same time, the temperature of seawater varies greatly throughout the year. The overall economy will also affect the vacuum degree of the condenser of the steam turbine generator set, which will further affect the oxygen content in the condensed water and the operating life of the steam generator
