| 摘要 |
The present invention relates to a seawater desalination apparatus, comprising: a heater for heating seawater, and a condenser for transferring the heat of the water vapor generated from the heated seawater to the seawater to be injected into the heater, wherein a gaseous heat source is brought into direct contact with the seawater which is a liquid object to be heated so that direct heat exchange is performed between the heat source and the seawater in the heater. Consequently, direct combustion gas or high-temperature gas such as water vapor or the like introduced from an external generating plant is mixed with the seawater which is a liquid object to be heated, to transfer heat to the seawater and to thus improve heating efficiency. In addition, the condenser or the heater is free of a high pressure, to thereby reduce manufacturing and maintenance costs and the size of the apparatus. |
