となるように補給される。BACKGROUND ART Conventionally, in steam power stations where boilers, steam turbines, etc. of ships and the like are installed, where fresh water cannot be easily obtained, water machines such as multi-effect cans are installed to extract fresh water from seawater. That is, as shown in FIG. 1, seawater 1 is introduced into a water dispenser 2, fresh water is collected, and concentrated seawater 3 is discarded. The fresh water sampled above is introduced into the receiver 5 as water for the boiler, and a considerable portion is used as water 4 for daily use such as drinking water.The fresh water in the receiver 5 is fed to the boiler 7 by the boiler pump 6. It is pumped to generate steam. This steam drives a steam turbine 8 that powers a generator, etc., is then cooled and condensed by seawater in a condenser 9, is returned to the liquid receiver 5, and is again sent to the boiler 7 by the boiler pump 6@as described above. Boiler water is circulated ◎Also, a gas-liquid multiphase flow occurs inside the tubes of the boiler, which corrodes the inner surface of the boiler tubes, but a can cleaning agent is usually added to prevent this corrosion. Therefore, boiler circulating water cannot be used for other purposes. The amount of circulating water in the boiler decreases due to extraction from the drain separator 10 of the boiler 7, partial one-pass heating, etc., but fresh water from the water dispenser 2 is replenished to keep the water amount constant. The can cleaning agent is also replenished so that the concentration remains constant.
ところで、スペースの限られた上記船舶などにおいて、

る。By the way, in the ships mentioned above where space is limited,
It is important to reduce the space taken up by equipment;
Various efforts have been made to reduce equipment space.

真水を回収するようにしたものである。In view of the above circumstances, it is an object of the present invention to provide a steam power station system that does not require a water generator such as a multi-effect can. Then, this is flashed through a pressure reducing valve to separate it into steam and concentrated seawater into a gas phase and a liquid phase, and after driving an expander with the steam, the discharged steam is condensed in a condenser to recover fresh water. This is what I did.
以下本発明を図面を参照して説明する。The present invention will be explained below with reference to the drawings.

高温に予熱する。FIG. 2 shows an embodiment of a steam power station according to the present invention. First, seawater 1 is introduced into a condenser 12 by a seawater supply pump 11, and exhaust steam from an expander, which will be described later, is condensed and the seawater is preheated.Then, this water is passed through a heat exchanger 1.
3, and further preheated to a high temperature using high-temperature, high-pressure concentrated seawater, which will be described later.

気の一部は、加熱その他の用途に使用してもよい。This preheated seawater is forced into the heater 14 and heated to a predetermined temperature while maintaining the liquid phase. The heated seawater passes through a check valve 15 and is flushed by a pressure reducing valve 16 to reduce its pressure to a predetermined value, and is then introduced into a gas-liquid separator 17 where it is separated into vapor and concentrated seawater into a gas-liquid phase. Most of this separated steam is led to and drives the expander 18, and the discharged steam is condensed in the condenser 12i and used as water 4 for daily use such as drinking. Note that a part of the steam from the gas-liquid separator 17 may be used for heating or other purposes.

The sea water is guided to a pressure reducing machine (for example, a water turbine) 19 that recovers pressure energy, and the pressure energy held therein is recovered and becomes low pressure, which is then disposed of as waste concentrated seawater 3.

17のクッション作用に負うものである。Seawater 1 is first sent through a condenser 12 and a heat exchanger 13 by a feed pump 11 . During this period, the thermal energy of steam and seawater is collected by preheating the seawater. Therefore steam and concentrated tUJ
It is possible to sufficiently recover the thermal energy held by water. In addition, since the seawater in the heater 14 is in a liquid phase, unlike a gas-liquid multiphase flow, corrosion of the heating pipe is less likely to occur.
It is less than G multiphase flow. In addition, the condensed water in the condenser 12 can be used once as daily water 4. The steam and condensed seawater are flushed by the pressure reducing valve 16 and introduced into the gas-liquid separator 17. Effect I
This allows subsequent energy recovery operations to be carried out smoothly. In particular, recovery of the pressure energy possessed by the commercially concentrated seawater from which thermal energy has been recovered is due to the cushioning effect of the gas-liquid separator 17.
