and 3a. A fresh water tray 4 is provided to partition both tube groups. Seawater is pumped up by a seawater pump 5, enters the condenser 3 through a pipe 6, and is discharged via a pipe 61 . A valve 7 is provided in the pipe line connecting the pipe lines 6 and 61 in a bridge manner. This valve 7 is closed while the freshwater generator is in operation, but when the freshwater generator is in operation, the valves 7a and 7b provided in the pipes 6 and 61 are closed and the valve 7 is opened, allowing the seawater to flow directly into the sea. Used for disposal. The cooling seawater, which has absorbed heat in the condenser 3 and has been heated, is supplied to the brine heating chamber 8 via a valve 18 via a pipe 6 2 branching from the pipe 6 1 . Concentrated supply seawater (brine) overflows a brine discharge pipe 17 located at the center of the water generator and controls the water level, and is discharged from a valve 9 via a discharge pipe 10.

A valve 12 is provided in the pipe connecting the pipes 11 and 11 1 through a bridge, and valves 12 a and 12 b are provided in the pipes 11 and 11 1 , which are used when the fresh water generator is out of operation. The seawater heated by the heat transfer tube group 2a of the heater 2 is transferred to the main body 1.
Since the pressure inside a is reduced to about -700 mmHg, it evaporates rapidly, and the water vapor and non-condensable gas pass through the mist separator 22 and come into contact with the heat transfer tube group 3a of the condenser 3, as shown in Figure 2, to exchange heat and become water vapor. is condensed to become fresh water, which accumulates in the fresh water tray 4, and is sent via a pipe 14 to a fresh water tank (not shown) by a fresh water pump 13 via a pipe 14a.

るものである。 Seawater contains scale components such as Ca and Mg, so in order to prevent these from adhering to the surface of the heating tube, a phosphoric acid-based scale inhibitor (for example, product name: Kryfloat M203, etc.) is pumped from the chemical tank 18 to the pump 19. The seawater is supplied to the heating chamber 8 via the conduit 21 together with the seawater from the conduit 20 including the valve 20a and the orifice 20b. This chemical solution makes the scale attached to the tube surface porous, making it easier to peel off from the tube.

る。 As the mist separator, synthetic resin wires (approximately 1 mm in thickness) are intertwined into a mat shape like a "tsutakazura" for ease of handling and low pressure drop. As shown in Figures 3 to 5, the mat is made by intertwining thick synthetic resin wires and heating them by pressing, etc. to form a thick rectangular member with an S-shaped cross section. It is used as a component. The mat is made of a highly corrosion-resistant wire such as a synthetic resin wire because of its corrosion resistance against seawater, ease of handling, cost, and other considerations. However, as shown in Figure 2, if the mat is left as a simple mat (plate-shaped), that is, fixed at both ends, brine water droplets, salt, etc. will accumulate inside the mat during operation, and the middle part will sag as shown in the diagram (indicated by the broken line). This is a problem as brine and precipitates accumulate at the bottom, increasing steam ventilation resistance.

とする。 The cross section of a pine made of wire with strong corrosion resistance against seawater is bent into an approximately S-shape, and one convex curved surface of the S-shaped cross section is placed on the upper side, with the top thereof located above the upper attachment point A. The water generating device is characterized in that the condensing side wall and the main wall of the water generating device are connected to each other so that the top of the lower convex curved surface is above the lower attachment point A, thereby forming a mist separator. .

The mist separator is made of bent synthetic resin wires with a diameter of about 1 mm that are intertwined like a ``tsutakazura'' to form a plate-like mat with a thickness of about 60 mm. As shown in FIGS. 3 and 4, one end of the mat 23 is attached to the vertical side wall 4a of the condenser with a bolt 23b so as to be pressed by a seat plate 23a. Bolt holes in mats can be easily drilled by applying a red-hot iron rod with the same diameter as the bolt.

水平に対して好ましくは約30゜にする。 The other end is attached to the side wall of the apparatus main body 1a with a bolt 23b' to a mounting bracket 23c. In this case, if the mounting point A on the condenser chamber side is selected to be higher than the mounting point B on the main body side, the mat 23 will form an S-shape in cross section with the convex curved surface facing upward as shown in the figure. In this way, even if water droplets or scale accumulate on the pine, they will not sag. The line connecting points A and B should preferably be approximately 30 degrees from the horizontal.

不具合を生ずることがない。 The thick pine suitable for carrying out this invention is S.
Since it is formed into a rectangular shape with a cross section in the shape of a letter, it has a large resistance to bending, and the surface of the pine with an S-shaped cross section is all sloped, making it easy to remove the mist liquid and creating a hanging part. This prevents problems such as deposits forming on the surface of the air and increasing the flow resistance of mist-containing steam.

上の端部固定板２４を設けてマツトの垂れ下りを
防止する。 Furthermore, when the distance between points A and B is large, one or more end fixing plates 24 are provided in the middle to prevent the pine from sagging.
