めたことを持ａとするが１水の淡水化装置である。The present invention aims to improve this point and provide a method and apparatus for obtaining fresh water from seawater by effectively utilizing the latent heat released when vapor returns to liquid and the nature of concentrated liquid. Yes, the gist of this is that seawater is sent to the water storage tank, water storage tank (I3), heat exchanger, and condenser in that order, and after being heated in the heater, it is heated at the evaporator gate. It is divided into an evaporated portion and a residual portion, and the evaporated portion is introduced into the condenser and condensed into fresh water by indirectly contacting the seawater flowing therethrough, and the fresh water is then passed through the heat exchanger to the above. The fresh water is stored in the water storage tank (4), and heat exchange occurs between the fresh water and the introduced seawater in this heat exchanger and the water storage tank (4), while the remaining portion is transferred to the water storage tank (B) through the heat exchanger. ) of the heat exchanger and the water storage tank, and heat exchange is caused between the residual portion and the introduced seawater in the heat exchanger and the water storage tank (5); A water storage tank (I3), a heat exchanger, a condenser, a heater, and an evaporator are connected in this order as described above, and the water is heated in the heater and evaporated in the evaporator. The evaporator, condenser, heat exchanger, and water storage tank (N are connected in this order) so that 81 cars worth of evaporation is sent to the water storage tank via the condenser and exchanger. The remaining portion was heat exchanged as described above 8.
The evaporator and the heat exchanger (and the water storage tank (13)) are connected in this order so that the water is sent to the water storage tank (13) via the water storage tank (13).
