発するべく鋭意研究を重ねた結果、本発明を完成した。The inventor of the present invention earnestly investigated the cause and found that the biggest cause was that the condensed water formed nearly spherical water droplets on the condensation surface. The large adhesion water vapor pressure increases the water vapor pressure near the condensing surface, and the temperature of the condensing surface causes a supercooling phenomenon, thus reducing the condensing efficiency, and the water droplets formed under such conditions are lower than the condensing surface. Because the temperature is low and the thermal conductivity of water is poor, the latent heat of condensation cannot be quickly transferred to the condensing surface, resulting in a decrease in the condensation efficiency and heat transfer efficiency of the area where water droplets are attached. They found that the formation of such water droplets was prevented and the above (1)
The present invention has been completed as a result of intensive research to develop a condensing section having a condensing surface having the properties of ) to (5).

ての効率も向上させ・ることができる。Generally, it is not known that ceramic thin films formed from inorganic paints have excellent wettability, and therefore no applications utilizing this property have been developed. By the way, in the condensation section of the aqueous solution distillation apparatus to which the present invention is directed,
As mentioned above, when water droplets adhere to the condensing surface, the distillation efficiency decreases. In particular, the closer the adhesion of water droplets is to granules, the longer they stay on the condensing surface.Moreover, the thermal conductivity of water is poor, so the latent heat of condensation cannot be transferred quickly, and the water vapor in the vicinity of the adhering water droplets increases. Condensation efficiency decreases due to increased pressure. When the condensation surface of the distillation device is formed from a ceramic thin film layer with excellent wettability formed from an inorganic paint as described above, condensed condensation is less likely to occur than when the ceramic thin film layer is not formed. At 14 minutes after starvation L-1, the condensation efficiency of the distillation device can be improved, and the surface on the back side of the condensation surface can be improved. Thermal conductivity to the evaporation surface present in the evaporation surface is improved, and the efficiency of the distillation apparatus as a whole can also be improved.

水性が向上する。As a method for forming the ceramic thin film layer, a method normally used for inorganic paints is employed. For example, an amorphous paint may be applied to the mirror surface of the substrate by spray coating, coater coating, etc., and dried and baked at room temperature to about 150°C. Although the drying firing temperature and time vary depending on the material of the substrate, in general, the higher the temperature and the longer the drying time, the better the water resistance.
