Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in further detail the utility model below in conjunction with the drawings and specific embodiments.
The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
In order to understand the utility model more clearly, operate to example below with seawater desalination system, composition graphs 1 is described further Nuclear power plants seawater desalination system of the present utility model.
Nuclear power plants seawater desalination system is arranged on outside the reactor housing of reactor, by the heat-exchanging loop between vapour line and water-supply line, carries a large amount of heats to seawater.When running without the need to seawater desalination system, by heat exchanger inlets variable valve 6 and heat exchanger outlet vacuum breaker 9, heat exchanger 8 is isolated with main steam pipe 2 and water-supply line 13.
When needs seawater desalination system puts into operation, open heat exchanger inlets variable valve 6, part main steam enters heat exchanger 8, after transferring heat to seawater, vapour generator 1 is entered through service pump 10, feedwater isolation valve 11 and feed-regulating valve 12 and water-supply line 13, form closed cycle, and balance of ensuring the quality of products.Water in seawater bin 21 enters heat exchanger 8 through seawater desalination system back with water inlet line 23, seawater working shaft 24 and seawater for water regulating valve 25, enters flash tank 17 after being heated through seawater desalination system hot water line 15 and flash tank water inlet reducing valve 16.By seawater flash distillation in flash tank 17 of heating, the steam flashed off enters flash-off steam pipeline 26.Flash-off steam can be supplied to steam user 28 after flash-off steam variable valve 27, also can enter flash distillation fresh water pipeline 29, enter condenser 32 after fresh water pipe line control valve 30, after supercooled water 31 cools, is supplied to fresh water user 33.The hydrophobic of flash tank 17 through flash tank drain pipe 18 and the hydrophobic reducing valve 19 of flash tank, can be supplied to Industrial Salt user or next stage flash tank 20.Liquid level in seawater water tank 21 is maintained by source of seawater 22.
