Detailed Description

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a longitudinal sectional view of a water producing apparatus according to an embodiment of the present invention. The water producing apparatus 1 of the present embodiment is of a double effect type including: a heater 10 for heating the liquid to be treated to generate steam; a housing 40 disposed at an upper portion of the heater 10; and a condenser 50 supported to penetrate the center of the casing 40 and having a center portion housed in the casing 40.

In the heater 10, a lower opening and an upper opening of a cylindrical container body 11 are covered with a bottom plate 12 and a closing plate 13, respectively, to form a closed space therein. The container body 11 is partitioned by a partition plate 14 extending vertically to form a first heating chamber 20 and a second heating chamber 30.

A plurality of holes are formed in the bottom plate 12 and the closing plate 13, and a plurality of

heat transfer pipes

21 and 31 extending vertically so as to penetrate through the holes are disposed in the first heating chamber 20 and the second heating chamber 30, respectively.

The bottom plate 12 is connected to a seawater inlet 15 on the lower surface side. The seawater inlet 15 is formed in a disk shape, and the inside thereof is divided by a dividing plate 15a to form a first inlet chamber 15b and a second inlet chamber 15c. The first introduction chamber 15b and the second introduction chamber 15c communicate with the lower ends of the

heat transfer pipes

21 and 31, respectively, and the liquid to be treated such as seawater introduced from the

introduction ports

15d and 15e rises inside the

heat transfer pipes

21 and 31.

Supply ports

23, 33 and

discharge ports

24, 34 are formed in side walls of the first heating chamber 20 and the second heating chamber 30, respectively. The heating fluid supplied from the

supply ports

23, 33 is discharged from the

discharge ports

24, 34 through the outside of the

heat transfer pipes

21, 31. Baffles 25 and 35 that meander the flow path of the heating fluid are provided in the first heating chamber 20 and the second heating chamber 30, respectively. The

baffles

25 and 35 are held at predetermined height positions by cylindrical spacers (not shown) fitted around the

heat transfer pipes

21 and 31.

The case 40 is a cylindrical member having a diameter larger than that of the heater 10, and has an opening 41 formed in a lower portion thereof and an upper portion 42 covered with a cover plate. The peripheral edge of the opening 41 is connected to the peripheral edge of the closing plate 13, and the case 40 is sealed.

The interior of the housing 40 is partitioned by a partition wall including a lower partition wall 43 and an upper partition wall 44, forming a first gas-water separation chamber 60 and a second gas-water separation chamber 70. The first gas-water separation chamber 60 and the second gas-water separation chamber 70 include gas-

water separation plates

61 and 71 provided directly above the

heat transfer pipes

21 and 31, and demisters 62 and 72 arranged above the gas-

water separation plates

61 and 71. The

demisters

62 and 72 are known members formed by laminating mesh plates, and the lower surfaces thereof are supported by

support members

63 and 73 attached to the condenser 50.

Vapor discharge ports

64 and 74 for discharging generated vapor are formed in the upper portions of the first gas-water separation chamber 60 and the second gas-water separation chamber 70, respectively. Further,

drain ports

65 and 75 for discharging the liquid separated from the vapor are formed in the lower portions of the first gas-water separation chamber 60 and the second gas-water separation chamber 70, respectively.

The condenser 50 includes: a receiving member 51 in the form of a channel made of a corrosion resistant material such as stainless steel and arranged to extend horizontally and partitioned by the upper partition wall 44; and a plurality of heat transfer pipes 52 housed along the receiving member 51 on both sides of the upper partitioning wall 44, and a preheater 55 including the heat transfer pipes 52 disposed on the first gas water separation chamber 60 side of the upper partitioning wall 44 is built in. Heads (not shown) are provided at both ends of heat transfer pipe 52 at positions protruding outward from case 40. The liquid to be treated such as seawater introduced into the condenser 50 is partly introduced into the first introduction chamber 15b from the introduction port 15d via the preheater 55, and the remaining part is discharged as drain water.

In the water generating apparatus 1 having the above-described configuration, the seawater as the liquid to be treated supplied to the condenser 50 condenses the vapor in the second moisture separation chamber 70, and then a part of the condensed vapor is preheated by the preheater 55 and introduced into the first introduction chamber 15b, and passes through the inside of the heat transfer pipe 21 disposed in the first heating chamber 20.

Hot water usable in the field, such as jacket cooling water for a diesel engine mounted on a ship, for example, is supplied as a heating fluid from the supply port 23 to the first heating chamber 20, and is discharged from the discharge port 24 through a flow path formed by the baffle plate 25. Thereby, the seawater passing through the heat transfer pipe 21 is heated and evaporated in the heat transfer pipe 21, and is introduced into the first gas-water separation chamber 60.

The vapor introduced into the first gas-water separation chamber 60 is separated into liquid droplets by the gas-water separation plate 61 and the demister 62, and then a part of the vapor is condensed by the seawater passing through the heat transfer tubes 52 of the preheater 55 and recovered as fresh water. The seawater separated from the vapor in the first gas-water separation chamber 60 is discharged from the water discharge port 65, introduced into the second introduction chamber 15c, and passes through the heat transfer pipe 31 disposed in the second heating chamber 30.

The remaining vapor in the first gas-water separation chamber 60 is discharged from the discharge port 64, supplied to the supply port 33 of the second heating chamber 30 as the heating fluid, and then discharged from the discharge port 34 through the flow path formed by the baffle 35 to be recovered as fresh water. Thereby, the seawater passing through heat transfer pipe 31 is heated and evaporated in heat transfer pipe 31, and is introduced into second moisture separation chamber 70.

The droplets mixed with the vapor introduced into the second moisture separation chamber 70 are separated by the moisture separation plate 71 and the demister 72, and then a part of the vapor is condensed by the seawater passing through the heat transfer pipe 52 in the condenser 50 and recovered as fresh water. The seawater separated from the vapor in the second gas-water separation chamber 70 is discharged from the water discharge port 75 and recovered as brine. The remaining steam in the second steam-water separation chamber 70 is extracted by an ejector (not shown) or the like connected to the discharge port 74.

In the water producing apparatus 1 of the present embodiment, the treatment target liquid such as seawater is introduced into the

heat transfer pipes

21 and 31 of the first heating chamber 20 and the second heating chamber 30, and is evaporated in the pipes, and warm water is introduced into the first heating chamber 20 as the heating fluid, whereby condensed water can be generated by using low-temperature waste heat, and therefore, the water producing apparatus 1 can be downsized and highly efficient.

In the water producing apparatus 1 of the present embodiment, since the heating fluid in the first heating chamber 20 is warm water and the heating fluid in the second heating chamber 30 is steam, for example, the internal pressure of the first heating chamber 20 is 0.5MPa, and the internal pressure of the second heating chamber 20 is-0.1 MPa, which is different from this, and the pressure difference between both sides of the partition plate 14 is increased. In such a case, when the closing plate 13 is detachably provided to the vessel main body 11, the partition plate 14 is bent by the internal pressure difference of the steam, a gap is generated between the closing plate 13 and the partition plate 14, and the seawater enters the second heating chamber 30 from the first heating chamber 20 through the gap, which causes a decrease in the purity of the steam introduced into the second heating chamber 30.

In the present embodiment, as shown in fig. 2, a plurality of bolt holes 14a are formed at equal intervals in the upper end surface of the partition plate 14 integrally formed in the container body 11, and the bolt holes 14a of the partition plate 14 are used for connecting the closing plate 13 together with the bolt holes 11a formed in the peripheral flange portion of the container body 11, whereby the above-described problem is solved, that is, as shown in fig. 3, the bolt holes 13a and 14a are formed in the closing plate 13 and the partition plate 14, respectively, and the closing plate 13 is fixed to the upper end surfaces of the container body 11 and the partition plate 14 via a spacer 14b by a fastening member 16 such as a bolt. As described above, the closing plate 13 and the partition plate 14 can be detachably coupled by the coupling member 16, and thus, the occurrence of a gap due to deformation of the partition plate 14 can be reliably prevented while maintaining good maintainability. 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 coupled in the same manner as the coupling structure of the closing 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 abuts against the upper surface of the closing plate 13. As shown in fig. 3, a spacer 43a is provided between the housing 40 and the lower partitioning wall 43 and the closing plate 13, and the connector 16 inserted into the bolt hole 13a of the closing plate 13 is covered by the lower end surface of the lower partitioning wall 43. To prevent the coupler 16 from protruding from the upper surface of the closure plate 13, the coupler 16 is preferably a low-head bolt. With this structure, the coupled state of the closing plate 13 and the partition plate 14 by the coupling 16 can be maintained more reliably.

Fig. 4 is a plan view of the housing 40, showing a state in which the cover plate 42 is removed. Fig. 5 is a side view of the support member 63 attached to the support member 51. As shown in fig. 4 and 5, a plurality of brackets 64 horizontally projecting toward the first gas-water separation chamber 60 are fixed to one side wall of the horizontally extending receiving member 51 of the housing 40 by welding or the like. In the plurality of brackets 64, both end portions of the band-shaped support member 63 are attached to the brackets 64 with screws 64a, respectively. The support member 63 is fixed in a direction in which the width direction is vertical. The demister 62 has a shape and a size that occupy 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 width-direction edge portion of the support member 63 that is curved in a plan view.

A plurality of brackets 74 protruding horizontally toward the second moisture separation chamber 70 are fixed to the other side wall of the receiving member 51 by welding or the like, and both end portions of a strip-shaped support member 73 bent in a U shape are attached to the brackets 74, respectively, as in the support member 63 described above.

As described above, 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 thus the support members for the demisters 62 and 72 are not required on the inner wall surface of the casing 40. This eliminates the protrusions for supporting the

demisters

62 and 72 on the inner wall surface of the casing 40, and therefore, the operation efficiency during assembly can be improved. The case 40 is formed using an inexpensive material such as SS400, and the inner wall surface is easily subjected to corrosion-resistant coating, thereby achieving both cost reduction and durability.

Further, since the

support members

63 and 73 are attached to the condenser 50, the central sides of the

defoggers

62 and 72 are less likely to fall down, and the

defoggers

62 and 72 can be reliably supported by the

support members

63 and 73. The

mist eliminators

62, 72 are supported linearly by the edge portions of the strip-shaped

support members

63, 73, and thus the

mist eliminators

62, 72 can be stably supported while securing a vapor passage region. The support structure of the

defoggers

62 and 72 according to the present embodiment is particularly effective when the casing 40 is downsized and the installation space of the

defoggers

62 and 72 is narrow.

The shape of the

support members

63, 73 is preferably a U shape as in the present embodiment from the viewpoint of reliably supporting the entirety of the

defoggers

62, 72, but may be bent or curved into various shapes such as a polygonal shape and a wavy shape.

Further, the conventional fresh water producing apparatus disclosed in patent document 2 supports the peripheral edge of the demister by an engaging piece protruding from the inner wall surface of the closed tank. In such a demister supporting structure, the closed tank is formed of an inexpensive material having low corrosion resistance, and therefore, it is necessary to apply corrosion-resistant coating to the inner wall surface, but it takes time to completely coat the engaging piece, and there is a problem that the engaging piece becomes an obstacle and the operability is poor when the internal member is mounted. Further, the demister has a problem that the purity of condensed water is lowered because the demister is likely to fall on the opposite side of the inner wall side of the closed tank supported by the engaging piece and cannot stably perform gas-liquid separation.

One embodiment of the present invention has been described above in detail, and the specific embodiment of the present invention is not limited to the above embodiment. For example, although the partition plate 14 is reinforced by detachably fixing the closing plate 13 to the end surface of the partition plate 14 via the spacer 14b by the coupling 16 in the present embodiment, as shown in fig. 6, the reinforcing member 17 may be disposed in the second heating chamber 30 which is on the low pressure side with respect to the first heating chamber 20 of the vessel body 11.

The reinforcing members 17 are block-shaped members provided between the inner wall surface of the container body 11 and the side surfaces of the partition plates 14, and are arranged in plurality at intervals in the vertical direction. With this configuration, the partition plate 14 can be prevented from expanding toward the second heating chamber 30, and seawater can be prevented from entering the second heating chamber 30. Such a reinforcing structure by the reinforcing member 17 can also be used in combination with the above-described coupling structure of the closing plate 13 and the partition plate 14 by the coupling 16.

In the present embodiment, partition plate 14 of container main body 11 is provided in the vertical direction to divide the interior of container main body 11 into left and right sections, but first heating chamber 20 and second heating chamber 30 may be formed by providing partition plate 14 horizontally to divide the interior of container main body 11 into upper and lower sections.

In the present embodiment, the preheater 55 provided in the condenser 50 is disposed in the first moisture separation chamber 60, but as shown in fig. 7, the preheater 55 may be disposed in the second moisture separation chamber 70, and the liquid to be treated supplied to the condenser 50 may be partially preheated by the preheater 55 and introduced into the first introduction chamber 15b after the vapor in the second moisture separation chamber 70 is condensed, and the remaining part may be discharged as drain water. Alternatively, as shown in fig. 8, the preheater 55 may have a first preheater 55a disposed in the first moisture separation chamber 60 and a second preheater 55b disposed in the second moisture separation chamber 70, and the liquid to be treated supplied to the condenser 50 may be partially preheated in the second preheater 55b and the first preheater 55a and introduced into the first introduction chamber 15b after condensing the vapor in the second moisture separation chamber 70, and the remaining part may be discharged as drain water.

Further, although the water producing apparatus 1 of the present embodiment is of a double effect type, a container main body 11 is divided by a plurality of partition plates to form 3 or more heating chambers, and steam generated in a preceding heating chamber is used as a heating fluid in a succeeding heating chamber, whereby a multiple effect type having a weight of 3 or more can be formed. On the other hand, the demister may be supported by a support member fixed to the condenser, and the support member 63 may be supported by the receiving member 51 of the condenser 50 in any of the single-effect type or multiple-effect type water producing apparatuses without a partition plate. The mounting position of the support member 63 to the condenser 50 is not necessarily the receiving member 51 as in the present embodiment, and may be another position where the support member 63 can be mounted.

In the present embodiment, as shown in fig. 2, a coupling member such as a bolt is inserted through a gasket into a plurality of bolt holes 11a formed in a peripheral flange portion of the container body 11, but as shown in fig. 9, a weld portion W1 formed by fillet welding is formed over the entire circumference of the outer surface of the cylindrical end portion of the container body 11, whereby the container body 11 and the closing plate 13 can be coupled. The container body 11 and the bottom plate 12 can also be connected by forming a welded portion W2 on the outer periphery of the cylindrical end portion of the container body 11. In this case, the bottom plate 12, the closing plate 13, and the partition plate 14 can be coupled via a spacer coupler as in the present embodiment. Alternatively, as shown in fig. 10 (a), the closing plate 13 (or the bottom plate 12) and the partition plate 14 can be coupled by forming the welded portions W3, W4 on both sides in the thickness direction of the partition plate 14. As shown in fig. 10 (b), the closing plate 13 (or the bottom plate 12) and the partition plate 14 can be coupled to each other by forming a through hole 13b in the closing plate 13 (or the bottom plate 12) and forming a welded portion W5 in the through hole 13 b. The through hole 13b formed in the closing plate 13 is preferably formed at a position closed by a gasket 43a provided between the lower partition wall 43 and the closing plate 13.

The heating fluid mainly composed of vapor is introduced into the supply port 33 of the second heating chamber 30 at a high speed, and a retention portion having a collision plate against which the introduced heating fluid collides is provided between the supply port 33 and the second heating chamber 30, whereby the heat exchange efficiency of the heat transfer pipe 31 can be improved. However, in this configuration, the supply port 33 protrudes outward from the heater 10 to a large extent, which causes a problem that the water generator 1 is large in size. Then, as shown in fig. 11, it is preferable that a retention section 18 fixed by welding or the like is provided on the outer peripheral surface of the container main body 11, the internal space of the retention section 18 communicates with the second heating chamber 30 via a communication section 18a formed in the side wall of the container main body 11, and when the heating fluid is introduced into the retention section 18 from the supply port 33, the heating fluid collides with the outer peripheral surface of the container main body 11. According to this configuration, since the outer peripheral surface of the vessel body 11 functions as the collision plate, it is not necessary to newly provide the collision plate in the retention section 18, and the structure of the water producing apparatus 1 can be maintained compactly. The collision portion of the heating fluid on the outer peripheral surface of the container body 11 is not particularly limited, but is preferably below the communication portion 18 a.

Fig. 11 isbase:Sub>A sectional view showingbase:Sub>A modification of the heater 10 shown in fig. 9, taken along the sectionbase:Sub>A-base:Sub>A of fig. 9. The heating fluid introduced from the supply port 33 into the second heating chamber 30 flows in a meandering manner along the partition plate 14 by the

baffle plates

35, 35 arranged in the upper and lower directions, and is discharged from the discharge port 34. The interval S1 between the closing plate 13 and the upper baffle 35, the interval S2 between the upper and lower baffles 35, and the interval S3 between the lower baffle 35 and the bottom plate 12 are preferably S1> S2> S3. The number and arrangement of the baffles 35 in the second heating chamber 30 are not particularly limited, but since the heating fluid introduced from the supply port 33 gradually condenses inside the second heating chamber 30, the flow path of the heating fluid formed in the second heating chamber 30 by the closing plate 13, the plurality of baffles 35, and the bottom plate 12 is gradually narrowed from the upstream side to the downstream side in the same manner as the configuration shown in fig. 11, and the entire heat transfer pipe 31 can be efficiently heated.

The baffle plate provided in the second heating chamber 30 can also serve as the reinforcing member 17 shown in fig. 6. That is, as shown in fig. 12,

gaps

17a and 17b are formed between the reinforcing member 17 and the closing plate 13 and the bottom plate 12, respectively, whereby the flow of the heating fluid can be divided into the upper and lower portions of the reinforcing member 17. By causing the reinforcing member 17 to function as a baffle in this manner, it is not necessary to newly provide a baffle, and the number of assembly steps can be reduced. The flow of the heating fluid can be branched by forming a gap on the right and left sides of the reinforcing member 17 or by forming a plurality of openings or slits in the reinforcing member 17.

In the configuration for supporting the demister by the support member, in the present embodiment, the

support members

63 and 73 are fixed to the portion of the condenser 50 housed in the casing 40, but the

support members

63 and 73 may be fixed to a portion other than the inner wall surface of the casing 40. The heater 10 or the condenser 50 can be at least partially housed in the casing 40, and the

support members

63 and 73 can be fixed to the portion of the heater 10 or the condenser 50 housed in the casing 40 to support the

demisters

62 and 72. For example, the upper portion of the heater 10 shown in fig. 1 may be extended to be housed in the case 40, and the

support members

63 and 73 may be fixed to extend upward from the outer wall surface of the housed portion.
