The vacuum of the evaporator 20 and the rehydrator 30 is connected to the maximum negative pressure portion of the water jet crying 36. The heater 10 and the rehydrator 30 are provided with a plate-type heat exchanger, which is the same as the plate-type water-making device of the conventionally known plate. As shown in the perspective view of the main part of Fig. 2, the heating is performed. The device 10 is connected between two end plates 101 and 1〇2, and is composed of two types of transfer plates. Each of the 103a and 103b is formed by a plurality of alternate laminated layers, and the edge portions are joined by the connecting rods 10a and 10a.

Each of the heat transfer plates 10a, 103b The groove portions 108a and 108b are formed on one of the surfaces, and the groove portion 108a of the heat transfer plate piece 103a is for connecting between the two raw material water circulation ports 104 and 105. On the other hand, the two warm water flow ports 106 and 20 107 are provided. Isolated, and the groove portion 108b of the heat transfer plate l〇3b is used to isolate 2 The raw water circulation ports 104 and 105 are connected to each other, and the two warm water circulation ports 106 and 107 are connected to each other. The adjacent heat transfer plates 103a and 103b are sealed by a sealing gasket (not shown). In Fig. 2, in order to facilitate understanding, the flow path formed in the laminating direction of the heat transfer plates 10a, 3b, and 3b is indicated by a solid line in a portion where the dashed line 10 200800807 does not communicate with the grooves 108a and 108b. The portion of the groove portion 1〇8a and 8〇8b is separated. By the heater 10, the raw material seawater and the warm water introduced from the raw material water inlet port 11 and the warm water inlet port 13 respectively flow through the heat transfer plate 1〇3& The groove portion 108a of the fifth groove portion 108a and the heat transfer plate piece 3b3b, so that the adjacent heat transfer plates i〇3a, i〇3b are viewed in the direction of lamination of the heat transfer plates 10a, 3b, 3b There is raw water and warm water in between. As a result, heat exchange between the raw material seawater and the warm water is performed via the heat transfer plates 103a and 103b. The seawater and warm water for the end of the heat exchange are discharged from the steam-concentrated brine outlet 12 and the warm water drain 10 outlet 14, respectively. The rehydrator 30 also has the same configuration as the heater 10. Between the two end plates 111 and 112, two types of heat transfer plates 113a and 113b are formed in a plurality of alternately laminated layers, and the edge portions are connected by The rods 30a, 30a are combined. Each of the heat transfer fins 113a and 113b is formed in a rectangular shape, and two distillation flow ports 114 and 115 which form a vapor (or distillation 15 water) flow path are disposed at a pair of corners, and two cooling waters which form a cooling water flow path are circulated. The ports 116, 117 are arranged in another diagonal. Each of the vapor introduction port 31, the distilled water discharge port 32, the cooling water introduction port 33, and the cooling water discharge port 34 is provided in one of the end plates 1 and connected to the plurality of heat transfer plates 113a and 113b, respectively, by distillation. a flow path formed by the flow port 114, a flow path formed by the distillation flow port 115, a flow path formed by the cooling water flow port 116, and a flow path formed by the cooling water flow port 117. Each of the heat transfer plates 113a and 113b The groove portions 118a and 118b are formed on one of the grooves, and the groove portion 118a of the heat transfer plate 113a is used to communicate between the two distillation ports 11 200800807 between the flow ports 114 and 115, and on the other hand, the two cooling water flow ports 116 and 117. It is isolated, and the groove portion 118 of the heat transfer plate 113b is used to isolate between the two distillation flow ports 114, 115, and the two cooling water flow ports 116, 117 are in communication. The heat exchange sheets 113a and 113b adjacent to each other are sealed by a sealing gasket (not shown). In addition, in the second drawing, in order to facilitate understanding, the flow paths formed in the stacking direction of the heat transfer plates 113a and 113b are indicated by broken lines to indicate the portions communicating with the groove portions 118a and 118b, and are separated from the groove portions 118a and 118b by solid lines. section. According to the configuration of the rehydrator 30, the water vapor and the cooling water introduced from the vapor introduction port 31 and the cooling water 10 inlet 33 pass through the groove portion 118a of the heat transfer plate piece 113a and the groove portion 118b of the heat transfer plate piece 113b, respectively. When the heat transfer sheets 113a and 113b are stacked, water vapor and cooling water pass through each other between the adjacent heat transfer sheets 113a and 113b. As a result, heat exchange between the water vapor and the cooling water is performed via the heat transfer plates 113a, 113b. The distilled water and the cooling water which are formed by the end of the heat exchange thickness 15 are discharged from the distilled water discharge port 32 and the cooling water discharge port 34, respectively. The cooling water discharged from the cooling water discharge port 34 is heated by heat exchange with water vapor, and is partially introduced into the heater 10 as raw material seawater. This configuration is the same as the conventional plate-type water-making device. However, if the cooling water is used as the raw material seawater, the temperature of the seawater of the raw material cannot be sufficiently increased, and the temperature of the raw seawater is raised to the temperature required for evaporation. A large heat transfer area is required in the heater 10. This is because the flow rate of the raw material seawater between the heat transfer sheets 10a3a is very slow, and a good heat transfer coefficient cannot be obtained, which can be clearly understood by the inventors. 12 200800807 Therefore, in the present embodiment, a preheating device is provided in order to raise the temperature of the raw seawater introduced into the heater 10 to a temperature close to the evaporation temperature. Specifically, as shown in Fig. 1, a heat exchanger 40 is disposed between the cooling water discharge port 34 and the raw material water introduction port 11, and is introduced into the warm water of the heater 1 5. A part of the isothermal water of the outer casing cooling water is used as a heating source of the heat exchanger 40, and the temperature of the raw material seawater passing through the heat exchanger 4 can be efficiently increased to a desired temperature. According to the plate-type water-making apparatus 1a of the present embodiment, a part of the cooling water discharged from the rehydrator 3 is heated in the heat exchanger 40, and then the seawater is introduced as the raw material 10 into the heater 10. Therefore, along the The raw material seawater flowing through the heat transfer sheet i〇3a of the heater 10 is evaporated at an initial stage, and can exchange heat with the warm water flowing along the heat transfer sheet 103b at a high speed. Therefore, since the heat transfer coefficient of the heater 10 can be increased, the miniaturization and low cost of the heater 1 can be achieved. The configuration of the heat exchanger 40 is not particularly limited, and may be, for example, a plate type heat exchanger. Since the number of sheets of the plate-type heat exchanger is easy to adjust, the preheating temperature of the raw seawater is easily controlled, and the flow rate of the fluid can be increased, so that the heat exchange efficiency can also be improved. Further, it is also possible to achieve an effect that the flow path is less likely to occur. 20 (Second Embodiment) - Fig. 3 is a schematic configuration view of a plate type water generator according to a second embodiment of the present invention, and Fig. 4 is a perspective view of a main part of the rehydrator. The plate-type water-making device 1b of the present embodiment is installed in the preheating unit of the raw material seawater in the rehydrator 30, and is replaced by the younger one.> The sad plate-type water-making device 1a is provided with a heat exchanger 13 200800807 40. In the third and fourth embodiments, the same components as those in the first embodiment shown in Figs. 1 and 2 are denoted by the same reference numerals and the description thereof will not be repeated. As shown in Fig. 4, the water repregator 39 of the present embodiment is provided with a partition plate 39a between the adjacent two heat transfer plates 113a and 113b. The partition plate 3 has the distillation flow ports 114, 115 and the cooling water flow port 116 as in the case of the heat transfer plates 113a and 113b, and the cooling water flow port 117 through which the introduced cooling water can pass is not provided. Further, the other end plate 112 forms a raw material seawater discharge port 10 which communicates with the cooling water introduction port 33 via the cooling water circulation ports 116 and 117 of the heat transfer plates 113a and 113b and the cooling water circulation port 116 of the partition plate 39a. 341 ° In the rehydrator 39 having the above configuration, the cooled seawater introduced by the one end plate 111 via the cooling water introduction port 33 exchanges heat with water vapor through a portion of the laminated heat transfer plates 113a, 113b. And a part of the cooled seawater after the heat exchange is discharged from the one end plate 111 via the cooling water discharge port 15 outlet 34. The residual portion of the cooled seawater after the heat exchange is again exchanged with the water vapor via the remaining portions of the laminated heat transfer sheets 113a and 113b, and is discharged from the raw material seawater discharge port 341 of the other end plate 112. The cooled seawater discharged from the raw material seawater discharge port 341 is introduced into the raw material water introduction port 11 of the heater 10 as shown in Fig. 3 . The rehydrator 39 in the plate type water generator lb of the present embodiment is heat-exchanged between the cooled seawater discharged from the raw material seawater discharge port 341 and the water vapor, and is disposed between the partition plate 39a and the other end plate 112. Further, since heat exchange is performed with water vapor, the temperature of the cooled seawater discharged from the rehydrator 30 shown in Fig. 2 is high. In other words, the rehydrator 39 of the present embodiment forms a preheating portion 41 for preheating the seawater of the raw material introduced into the heater i, between the partition plates 39a and 14 200800807 - 5 • 10 and the other end plate 112. The same effect as the first embodiment can be achieved. The temperature or flow rate of the cooled seawater discharged from the raw material seawater discharge port 341 can be easily adjusted by appropriately selecting the insertion position of the partition plate 39a between the plurality of laminated heat transfer plates 113a and 113b. In other words, as the insertion position of the partition plate 39 & is moved from the other end plate 112 side to the one end plate U1 side, the temperature of the raw material seawater discharged from the raw material seawater discharge port 341 becomes high, and the heat recovery rate increases. In the present embodiment, only one partition plate 39a is provided. However, when a plurality of heat transfer plates 113a and 113b are present between the partition plate 39a and the other end plate 112, a partition plate may be further provided. Its heat exchange with water vapor can be repeated. Further, the means for forming the flow path of the cooling water is not necessarily limited to the configuration in which the partitioning plate 39a is provided, and may be, for example, a switch having a cooling water flow port in which the heat transfer plate 113a or 113b is closed. Other components. 15 • The rehydrator 39 of the present embodiment can be formed by providing a preheating unit 41 by a small improvement of the existing rehydrator, so that it can be further miniaturized, and when the heat exchanger is provided It is especially effective when limited. Further, since the preheating unit 41 is a plate-type heat exchanger, the same effect as when the heat exchanger 40 of the first embodiment is a plate type can be obtained. In particular, the effect of clogging the flow path is not as significant as in the case of the present embodiment, and the reheater 39 has the preheating portion 41. (Embodiment 3) FIG. 5 is a schematic configuration view of a plate-type water-making apparatus according to a third embodiment of the present invention, and FIG. 6 is a perspective view of a main part of the heater. The plate of the present embodiment 15 200800807 The sheet type water generating device is provided with a preheating unit for the raw material seawater in the heater, in place of the plate type water generator la+ of the first embodiment. In the fifth and sixth embodiments, the same components as those in the first embodiment shown in Figs. 1 and 2 are denoted by the same reference numerals, and the description thereof will be omitted. As shown in Fig. 6, the heater 19 of the present embodiment is provided with a partition plate 19a between two adjacent heat transfer sheets 1 and 103b. The partition plate 19a is provided with the raw material water circulation ports 1〇4, 1〇5 and the warm water circulation ports 106 and 107 in the same manner as the heat transfer plate sheets 10a and 3b, and is not provided for introduction. The raw material seawater φ passes through the raw material water circulation port 105. Further, the raw material water introduction port η is not provided with one end plate 101, but is provided to the other end plate 102, and the raw material water introduction port passes through the raw material water circulation ports 104, 105 of the heat transfer plate sheets 10a, 103b and The raw material water circulation port 104 of the partition plate 19a is in communication with the steam-moisture salt outlet 12. In the heater 19 having the above configuration, the raw material seawater introduced from the other end plate 1〇2 through the raw material 15 water introduction port 11 Heat exchange with warm water is carried out through a portion of the laminated heat transfer sheets 103a, 103b, and the raw seawater after the heat exchange is further exchanged with heat through the heat transfer sheets 10a, 1〇3 of the residual portion, and then The one end plate 111 is discharged through the water vapor-concentrated brine outlet 12. The heater 19 in the plate-type water-making apparatus of the present embodiment is configured such that the raw material seawater introduced from the other end plate 102 is heat-exchanged between the partition plate 19a and the other end plate 102, and further heated with warm water. Heat exchange is performed so that the preheating portion 41 for preheating the raw seawater is formed between the knife partition 19a and the other end plate 1A. Therefore, the plate type water generator of the present embodiment can also achieve the same effects as those of the first embodiment up to 16 200800807. The temperature of the raw material seawater passing through the raw material water circulation port 10 of the partitioning plate 19a can be easily adjusted by appropriately selecting the insertion position of the partitioning plate 19a to the most laminated heat transfer sheets 10a, 103b. That is, as the insertion position 5 of the partitioning plate 19a is moved from the other end plate 102 side to the one end plate 101 side, the temperature of the raw material seawater passing through the raw material water circulation port 1〇4 of the partitioning plate 19a becomes high. In the present embodiment, only one partition plate 19a is provided. However, if there are a plurality of heat transfer plates 10a, 103b between the partition plate 19a and the other end plate 102, it may be configured to further separate the partitions. The heat exchange of the plates with water vapor 10 can be repeated. Further, the means for forming the flow path of the raw material seawater is not necessarily limited to the configuration in which the partitioning plate 19a is provided, and may be, for example, a raw material water flow port 1〇5 for closing the heat transfer sheet 103a or 103b. Other components such as switches. The heater 19 of the present embodiment can be configured with a preheating portion 42 by a small improvement 15 of the existing heater, so that it can be further miniaturized, and is particularly effective when the heat exchanger installation space is limited. . Further, since the preheating unit 42 is a plate-type heat exchanger, the same effect as in the case where the heat exchanger 40 of the first embodiment is a plate type can be obtained. Further, in the plate-type water-making device 1c of the present embodiment, the configuration of the rehydration device 30 is the configuration of the rehydrator 39 of the second embodiment shown in Fig. 4, and is configured to be The raw material seawater introduced into the heater 19 by the raw material seawater discharge port 341 of the water tank 39 can be further reduced in size and efficiency.
