積を大きくする必要があるという欠点がある。At present, various types of seawater desalination equipment are provided, and one similar to the present invention is an evaporation-type multi-stage flash type seawater desalination equipment (Japanese Patent Publication No. 41-1986-1).
No. 14898) When seawater from the sea is directly introduced (without heating) into a freshwater generator, the heat transfer area of the water generator's evaporator must be increased to ensure a constant amount of fresh water due to the low seawater temperature. The disadvantage is that it needs to be large.
本発明の目的は、造水装置蒸発器伝熱面積を小さくする
ことができる海水淡水化装置を提供することＫある。An object of the present invention is to provide a seawater desalination device that can reduce the heat transfer area of the evaporator of the water production device.

ラントの復水器出口の温められた海水を用いる点にある
。A feature of the present invention is that warmed seawater at the outlet of a condenser of a steam plant is used as the seawater introduced into the evaporator of the fresh water generator.

の伝熱面積を小さくすることができる。Generally, the local temperature distribution of the evaporator heat exchanger tube is as shown in FIG. In FIG. 1, if the evaporator inlet seawater temperature Tel is raised to Tc,', the heat exchanger tube length can be shortened from flL to L'. Therefore, the heat transfer area of the fresh water generator evaporator can be reduced as a result.
以下本発明の実施例を図面を用いて説明する。 Embodiments of the present invention will be described below with reference to the drawings.

空ポンプ８によって真空にされている。In FIGS. 2 and 3, cold seawater l discharged from the circulating water pump 9 undergoes heat exchange in the condenser 2 and becomes warm seawater 3. A portion of the warm seawater is guided to the evaporator 4, where the seawater is heated on the surface of the heat transfer tube 5 and emits purple light. The evaporated water vapor is led to the Iv rice bowl 6 and condensed to produce fresh water 7. Evaporator 4 and condenser 6 are evacuated by vacuum pump 8.

プ９出口の海水ｌを用いているので、特に冷却水供給の
ためのポンプを必要としない。In this embodiment, seawater l from the outlet of the circulation pump 9 is used as the cooling water for the condenser 6, so a pump for supplying cooling water is not particularly required.

としての熱効率の向上が計れる。As a heating method for the evaporator, steam 11 from the steam turbine IO is used, and the output rod 12 is sent to the heater 13 and returned to the condensate system. At this time, as shown in Fig. 1, the outlet drain humidity T H2' fl and the condenser outlet humidity T
The higher the temperature is than R2, the higher the heat recovery rate will be. Further, as a method of cooling the condenser 6, condensed water 14 at the outlet of the condenser is used, and water vapor is condensed to become fresh water 7. At this time, condensate 14
absorbs the latent heat of water vapor and recovers heat. Overall, it is possible to improve the thermal efficiency of the steam turbine plant and seawater desalination plant as a whole.
