冷却水として海水が用いられてｂる。Conventional seawater desalination equipment consists of an evaporator (flash evaporator) that generates steam from seawater and a condenser that condenses the generated steam. A vessel is used, and seawater is used as cooling water in the tube.

It requires heat transfer tubes, and seawater is used as the cooling water in the condenser tubes.
It has drawbacks such as scale adhesion and microbial contamination due to seawater passing through the heat transfer tube.

とする海水淡水化装置である。Ninth Means for Solving Problem C) In order to achieve the above object, the present invention uses an electric fusion type condenser that is brought into direct contact with fresh water instead of the multi-tubular surface type condenser. Furthermore, although the fresh water taken out from the electric fusion condenser is at a high temperature, this heat is recovered by exchanging it with raw seawater. That is, the present invention provides a seawater desalination apparatus comprising an evaporator that generates steam from seawater and a condenser that condenses the generated steam, in which an electrolytic condenser that is brought into direct contact with fresh water is used as the condenser, and This seawater desalination apparatus is characterized in that it is equipped with a heat exchange device for exchanging heat between the fresh water from the electrofusion condenser and raw seawater.

昇し、電融式凝縮器２ａから高温の淡水が取出される。To explain the operation of this seawater desalination device, raw seawater 9 is introduced into the heat exchanger 3, where it is heat exchanged with high-temperature fresh water from the electric condenser 2a, and then heated to a predetermined temperature by the heater 4. Then, it is sequentially supplied to flash evaporators 1a, 1b, and Ic. The remaining evaporated seawater is transferred to the heat exchanger 3.
The steam generated in the flash evaporators 1a, 1b, and Ic is introduced into the flash evaporators 1a, 1b, and Ic and discharged after heat exchange with the raw material seawater 9, respectively.
Introduced into 2c. Each of the electrolytic condensers 2a, 2b, and 2c is constructed so that low-temperature fresh water, which is lower than the internal pressure saturated steam temperature, falls in the form of water droplets in a pattern, so that the water droplets and steam come into direct contact with each other. As a result, the water droplets and the steam exchange heat, causing the steam to condense and mix with fresh water. The above-mentioned low-temperature fresh water is first introduced into the electrolytic condenser 5i2c from the fresh water tank 5 by the fresh water pump 7, where the steam is condensed to produce fresh water mixed with condensed water, and this fresh water is used as the low-temperature fresh water for the electrolytic condenser 2b. In addition, the low-temperature fresh water in the electric melt condenser 152a is the fresh water containing condensed water in the electric melt condenser 2b. In this way, the temperature of the low-temperature fresh water for steam 4 condensation increases in the order of the electro-fusion condenser 2C and 21% 2a, and the high-temperature fresh water is taken out from the electro-fusion condenser 2a.

ある。As described in detail above, the present invention uses an electric fusion type condenser in direct contact with fresh water instead of the conventional multi-tubular surface condenser as a condenser, so no heat transfer tubes are required. C,
This results in a significant cost reduction and the effect that there is no need to clean dirt generated on the heat transfer surface. Furthermore, since the present invention is equipped with a heat exchange device that exchanges heat between high-temperature fresh water from an electrothermal condenser and raw seawater, the heat of this high-temperature fresh water can be effectively recovered and used. It is.
