The first gas-water separation chamber 60 and the second gas-water separation chamber 70 are provided with gas-water separation plates 61 and 71 provided just above the heat transfer tubes 21 and 31 , and gas-water separation plates 61 and 71 arranged above the gas-water separation plates 61 and 71 . Mist eliminators 62 , 72 . The mist eliminators 62 and 72 are well-known members obtained by laminating screen plates, and the lower surface side is supported by the support members 63 and 73 attached to the condenser 50 .

Moreover, in the lower part of the 1st gas-water separation chamber 60 and the 2nd gas-water separation chamber 70, the drain ports 65 and 75 which discharge|release the liquid separated from the vapor|steam are respectively formed.

The condenser 50 is provided with a groove-shaped receiving member 51 and a plurality of heat transfer tubes 52. The above-mentioned receiving member 51 is arranged to extend horizontally and is formed of a corrosion-resistant material such as stainless steel, and the interior is separated by an upper partition wall 44.

Part of the liquid to be treated such as seawater introduced into the condenser 50 is introduced into the first introduction chamber 15b from the introduction port 15d through the preheater 55, and the remainder is discharged as drain water.

The water generator 1 having the above-mentioned structure condenses the steam in the second gas-water separation chamber 70 of the seawater as the liquid to be treated supplied to the condenser 50, and then partially preheats it in the preheater 55 and introduces it into the first introduction. The chamber 15b passes through the inside of the heat transfer tube 21 arranged in the first heating chamber 20 .

In the first heating chamber 20, warm water that can be used on site, such as jacket cooling water of a diesel main engine mounted on a ship, is supplied from the supply port 23 as a heating fluid, and passes through the flow path formed by the interference plate 25. Instead, it is discharged from the discharge port 24 . Thereby, the seawater passing through the heat transfer tubes 21 is heated, evaporated in the heat transfer tubes 21 , and introduced into the first gas-water separation chamber 60 .

After the steam introduced into the first gas-water separation chamber 60 is separated by the gas-water separation plate 61 and the mist eliminator 62 after the mixed liquid droplets, a part of the steam is separated by the seawater passing through the heat transfer pipe 52 of the preheater 55 . is condensed and recovered as fresh water.

The seawater separated from the steam in the second gas-water separation chamber 70 is discharged from the drain port 75 and recovered as brine. The remaining vapor in the second gas-water separation chamber 70 is evacuated by an ejector (not shown) or the like connected to the discharge port 74 .

In the water generator 1 of the present embodiment, a liquid to be treated, such as seawater, is introduced into the heat transfer tubes 21 and 31 provided in the first heating chamber 20 and the second heating chamber 30, respectively, and the inside of the tubes is evaporated, and By introducing warm water into the first heating chamber 20 as a heating fluid, low-temperature waste heat can be used to generate condensed water, so that the water generator 1 can be reduced in size and high in efficiency.

In the water generator 1 of the present embodiment, since the heating fluid of the first heating chamber 20 is warm water, and the heating fluid of the second heating chamber 30 is steam, for example, the internal pressure of the first heating chamber 20 is relatively If it is 0.5 MPa, the internal pressure of the second heating chamber 20 becomes -0.1 MPa, and the pressure difference between the two sides of the partition plate 14 becomes large. In such a case, when the blocking plate 13 is detachably provided on the container body 11 , the partition plate 14 is bent due to the internal pressure difference of the steam, and a gap is generated between the blocking plate 13 and the partition plate 14 . , seawater permeates from the first heating chamber 20 to the second heating chamber 30 through the gap, and the purity of the steam introduced into the second heating chamber 30 may be lowered.

Therefore, in this embodiment, as shown in FIG. 2 , a plurality of bolt holes 14 a are formed at equal intervals on the upper end surface of the partition plate 14 integrally formed on the container body 11 , and the bolt holes 14 a of the partition plate 14 are connected to each other. The above-mentioned problems are eliminated by using a plurality of bolt holes 11a formed in the peripheral flange portion of the container body 11 for connection with the blocking plate 13. That is, as shown in FIG. 3 , bolt holes 13 a and 14 a are formed in the blocking plate 13 and the partition plate 14 , respectively, and the blocking plate 13 is fixed to the container body 11 and the container body 11 through the gasket 14 b by means of couplings 16 such as bolt holes. The upper end surface of the partition plate 14 is provided. In this way, the connection between the blocking plate 13 and the partition plate 14 is detachably connected by the coupling tool 16 , thereby maintaining good maintainability and reliably preventing the generation of a gap due to the deformation of the partition plate 14 . Further, the bottom plate 12 and the lower end surface of the partition plate 14 may be integrally fixed by welding or the like, or may be detachably connected similarly to the connection structure of the blocking plate 13 and the partition plate 14 .

As shown in FIG. 1 , the lower partition wall 43 provided inside the casing 40 is provided so as to hang down from the lower surface of the receiving member 51 of the condenser 50 , and the lower end surface of the lower partition wall 43 is in contact with the upper surface of the blocking plate 13 . . As shown in FIG. 3 , the housing 40 and the lower partition wall 43 and the closing plate 13 sandwich the gasket 43 a , and the connector 16 inserted into the bolt hole 13 a of the closing plate 13 is covered by the lower end surface of the lower partition wall 43 . In order to prevent the connecting tool 16 from protruding from the upper surface of the blocking plate 13, it is preferable that the connecting tool 16 is a low-head bolt. With this configuration, the connected state of the blocking plate 13 and the partition plate 14 by the connecting tool 16 can be more reliably maintained.

FIG. 4 is a plan view of the housing 40 , showing a state in which the cover plate 42 is removed. 5 is a side view of the support member 63 attached to the receiving member 51 . As shown in FIGS. 4 and 5 , the housing 40 has a plurality of brackets 64 protruding horizontally toward the first gas-water separation chamber 60 fixed to one of the side walls of the horizontally extending receiving member 51 by welding or the like. In the plurality of brackets 64, both ends of the belt-shaped support member 63 are respectively attached to the brackets 64 with screws 64a. The orientation of the support member 63 in the vertical direction in the width direction is fixed. The defogger 62 has a shape and size that occupies the entire space between the inner wall surface of the housing 40 and the side wall of the receiving member 51, and is mounted on the widthwise edge of the support member 63 which is curved in plan view.

On the other side wall of the receiving member 51, a plurality of brackets 74 protruding horizontally toward the second gas-water separation chamber 70 are fixed by welding, and similarly to the above-described supporting member 63, a belt-shaped supporting member 73 bent in a U-shape is fixed. Both ends of the , respectively, are mounted on the brackets 74 .

In this way, the entirety of the demisters 62 and 72 can be supported only by the support members 63 and 73 attached to the condenser 50 , and the support members of the demisters 62 and 72 are not required on the inner wall surface of the casing 40 . . Therefore, since the protrusions for supporting the mist eliminators 62 and 72 do not exist on the inner wall surface of the casing 40, the work efficiency at the time of assembly can be improved. The casing 40 can be formed using an inexpensive material such as SS400, and the inner wall surface can be easily coated with a corrosion-resistant coating, so that both cost reduction and durability can be achieved.

In addition, the support members 63, 73 are attached to the condenser 50, so that the collapse of the demisters 62, 72 on the central side is less likely to occur, and the demisters 62, 73 can be reliably supported by the support members 63, 73. 72. Furthermore, the demisters 62 and 72 are linearly supported by the edges of the belt-shaped support members 63 and 73, so that the demisters 62 and 72 can be stably supported while securing the passage area of the steam. The support structure of the demisters 62 and 72 of the present embodiment is particularly effective when the housing 40 is miniaturized and the installation space of the demisters 62 and 72 is small.

The shape of the support members 63 and 73 is preferably U-shaped as in the present embodiment from the viewpoint of securely supporting the entirety of the mist eliminators 62 and 72. However, the shape of the support members 63 and 73 may be made into a polygonal shape or a corrugated shape by being flexed or bent. and other shapes.

Furthermore, in the conventional water generator disclosed in the above-mentioned Patent Document 2, the peripheral edge portion of the mist eliminator is supported by the engaging piece protruding from the inner wall surface of the airtight tank. Since the support structure of the mist eliminator is formed of an airtight tank with low corrosion resistance and inexpensive material, the inner wall surface needs to be coated with corrosion resistance, but it takes time and labor to beautifully coat the engaging pieces. , and when the internal parts are mounted, the engaging piece interferes, and there is a problem of so-called poor workability. In addition, since the mist eliminator tends to collapse on the side opposite to the inner wall side of the airtight tank supported by the engaging piece, and stable gas-liquid separation cannot be performed, there is a possibility that the purity of the condensed water may be lowered.

One embodiment of the present invention has been described in detail above, but the specific aspect of the present invention is not limited to the above embodiment. For example, in this embodiment, the blocking plate 13 is detachably fixed to the end face of the partition plate 14 through the gasket 14b and the connector 16 to reinforce the partition plate 14. However, as shown in FIG. 6 , it is also possible to The reinforcing member 17 is arranged in the second heating chamber 30 on the low pressure side with respect to the first heating chamber 20 of the container body 11 .

The reinforcing member 17 is a block-shaped member sandwiched between the inner wall surface of the container body 11 and the side surface of the partition plate 14, and a plurality of the reinforcing members 17 are arranged with a gap therebetween in the vertical direction. Even with this configuration, the bulging of the partition plate 14 toward the second heating chamber 30 can be suppressed, and the penetration of seawater into the second heating chamber 30 can be prevented. The reinforcing structure using the reinforcing member 17 in this way may be combined with the connecting structure using the blocking plate 13 and the partition plate 14 using the above-mentioned coupling tool 16 .

Moreover, in this embodiment, the interior of the container body 11 is divided into left and right by arranging the partition plate 14 of the container body 11 in the vertical direction, but the partition plate 14 may be arranged horizontally. The inside of the container body 11 is divided into upper and lower parts to form the first heating chamber 20 and the second heating chamber 30 .

In addition, in the present embodiment, although the preheater 55 provided in the condenser 50 is configured to be arranged in the first gas-water separation chamber 60, as shown in FIG. 7, the preheater 55 may be arranged In the configuration of the second gas-water separation chamber 70, the liquid to be treated supplied to the condenser 50 is partially preheated in the preheater 55 after condensing the vapor in the second gas-water separation chamber 70, and then introduced into the first introduction chamber. 15b, the remainder is discharged as drainage. Alternatively, as shown in FIG. 8 , the preheater 55 may include a first preheater 55 a arranged in the first gas-water separation chamber 60 and a second preheater arranged in the second gas-water separation chamber 70 . After condensing the vapor in the second gas-water separation chamber 70, the liquid to be treated supplied to the condenser 50 is partially preheated in the second preheater 55b and the first preheater 55a, and introduced into the first introduction Chamber 15b, the remainder is discharged as drain.

In addition, although the water generating device 1 of the present embodiment is a dual-function type, it is also possible to use a plurality of partition plates to separate the container body 11 to form three or more heating chambers, and to combine the water generated in the preceding heating chamber. The steam is used as the heating fluid of the heating chamber in the rear stage, and thus it can be used as a multi-function type with three or more layers. On the other hand, regarding the structure of supporting the mist eliminator by means of a support member fixed to the condenser, it can also be a single-effect type without a partition plate, and water generation in either a single-effect type or a multi-effect type. In the device, the supporting member 63 can also be supported by the receiving member 51 of the condenser 50 . The mounting position of the support member 63 to the condenser 50 does not necessarily need to be the receiving member 51 as in the present embodiment, and may be any other position where the support member 63 can be mounted.

The connection between the container body 11 and the closing plate 13 is shown in FIG. 2 in the present embodiment by inserting a connection tool such as a bolt through a gasket through a plurality of bolt holes formed in the peripheral flange portion of the container body 11. However, as shown in FIG. 9 , the container body 11 and the closing plate 13 may be connected by forming a welding portion W1 by fillet welding on the entire circumference of the outer surface of the cylindrical end portion of the container body 11 . The connection between the container body 11 and the bottom plate 12 may be performed by forming the welded portion W2 on the outer periphery of the cylindrical end portion of the container body 11 . In this case, the connection of the bottom plate 12, the blocking plate 13, and the partition plate 14 can be performed by a connection tool through a gasket, as in the present embodiment. Alternatively, as shown in FIG. 10( a ), the blocking plate 13 (or the bottom plate 12 ) and the partition plate 14 may be connected by forming welding portions W3 and W4 on both sides of the partition plate 14 in the thickness direction. Furthermore, as shown in FIG. 10( b ), a through hole 13 b can be formed in the blocking plate 13 (or the bottom plate 12 ), and a welded portion W5 can be formed in the through hole 13 b to connect the blocking plate 13 (or the bottom plate 12 ) and the split Separator 14 . The through hole 13b formed in the blocking plate 13 is preferably formed at a position closed by the spacer 43a sandwiched between the lower partition wall 43 and the blocking plate 13 .

Since the heating fluid mainly composed of steam is introduced into the supply port 33 of the second heating chamber 30 at a high speed, the heating fluid collides between the supply port 33 and the second heating chamber 30 by sandwiching the introduced heating fluid. The heat exchange efficiency of the heat transfer tube 31 can be improved by colliding with the retention portion of the plate. However, in this configuration, since the supply port 33 protrudes widely from the heater 10 to the outside, there is a possibility that the size of the water generator 1 may be increased. Therefore, as shown in FIG. 11 , a retention portion 18 fixed by welding or the like is provided on the outer peripheral surface of the container body 11 , and the inner space of the retention portion 18 passes through the communication portion 18 a formed on the side wall of the container body 11 . It is preferably connected to the second heating chamber 30 , and the heating fluid collides with the outer peripheral surface of the container body 11 when the heating fluid is introduced into the retention portion 18 from the supply port 33 . According to this configuration, since the outer peripheral surface of the container body 11 plays the role of the above-mentioned collision plate, there is no need to newly install the collision plate in the retention portion 18, and the structure of the water generator 1 is maintained in a compact size. The collision point of the heating fluid on the outer peripheral surface of the container body 11 is not particularly limited, but is preferably located below the communication portion 18a.

FIG. 11 is a cross-sectional view showing a modification of the heater 10 shown in FIG. 9 along the line A-A in FIG. 9 . The heating fluid introduced into the second heating chamber 30 from the supply port 33 flows along the partition plate 14 while meandering by the interference plates 35 and 35 arranged up and down, and is discharged from the discharge port 34 . The interval S1 between the blocking plate 13 and the upper interference plate 35, the interval S2 between the upper and lower interference plates 35 and 35, and the interval S3 between the lower interference plate 35 and the bottom plate 12 are preferably S1>S2>S3. The number and arrangement of the interference plates 35 in the second heating chamber 30 are not particularly limited. However, since the heating fluid introduced from the supply port 33 is gradually condensed in the second heating chamber 30, as shown in FIG. 11 In the same way, the heating fluid formed in the second heating chamber 30 by the blocking plate 13, the plurality of interference plates 35, and the bottom plate 12 is configured to gradually narrow from the upstream side to the downstream side. Therefore, the entire heat transfer tube 31 can be efficiently heated.

The interference plate provided in the second heating chamber 30 may also serve as the reinforcing member 17 shown in FIG. 6 . That is, as shown in FIG. 12 , between the reinforcing member 17 , the blocking plate 13 and the bottom plate 12 , by forming gaps 17 a and 17 b respectively, the flow of the heating fluid can be divided up and down the reinforcing member 17 . In this way, by making the reinforcing member 17 function as an interference plate, it is not necessary to newly provide a interference plate, and the installation man-hour can be reduced. The separation of the flow of the heating fluid by the reinforcing member 17 may be performed by forming gaps on the left and right sides of the reinforcing member 17 , or by forming a plurality of openings or notches in the reinforcing member 17 .

Regarding the structure for supporting the mist eliminator by the support members, in the present embodiment, the support members 63 and 73 are fixed to the part where the condenser 50 is housed inside the casing 40 , but the support members 63 and 73 may be fixed inside the casing 40 . The support members 63 and 73 are fixed to the places other than the inner wall surface of the middle.
