Description

[0001] This application is a divisional application of the invention entitled "Water Making Device" with patent application number CN201810869210.2 and original filing date of August 2, 2018. Technical Field

[0002] This invention relates to a water-making device. Background Technology

[0003] Water-making devices are known for both land and ship applications. However, in ship-based water-making devices, seawater has traditionally been evaporated using steam from the ship's boiler or cooling water from the diesel engine as a heat source to produce fresh water. Examples of existing water-making devices include those disclosed in Patent Document 1.

[0004] like Figure 13 As shown, in the multi-effect water making device 100, the interior of the sealed tank 101 is divided by a partition plate 102 to form a first evaporation chamber 103 and a second evaporation chamber 104. Heaters 105 and 106 with multiple heat conduction pipes 105a and 106a are respectively provided in the lower part of the first evaporation chamber 103 and the second evaporation chamber 104.

[0005] Steam supplied as a heat source heats the seawater supplied to the first evaporation chamber 103 by passing through the interior of the heat-conducting pipe 105a of the heater 105 of the first evaporation chamber 103, causing it to evaporate. The steam generated in the first evaporation chamber 103, after passing through the demister 107 located at the top of the first evaporation chamber 103, is supplied via conduit 108 to the heater 106 of the second evaporation chamber 104, where it heats the seawater supplied to the second evaporation chamber 104 by passing through the interior of the heat-conducting pipe 106a of the heater 106, causing it to evaporate. The steam generated in the second evaporation chamber 104 is introduced into the condenser 110 by passing through the demister 109 located at the top of the second evaporation chamber 104. The supports for the demisters 107 and 109 inside the sealed tank 101, for example as disclosed in Patent Document 2, are typically supported by snap-fit ​​tabs protruding from the inner wall of the sealed tank 101.

[0006] In the condenser 110, multiple heat pipes are divided by a partition plate 111 into a group of condensing heat pipes 112 and a group of heating heat pipes 113. Steam generated in the second evaporation chamber 104 is cooled by seawater passing through the interior of the condensing heat pipes 112, becoming condensate, which is discharged from the bottom outlet 114. A portion of the seawater heated by passing through the interior of the condensing heat pipes 112 is supplied to the interior of the heating heat pipes 113, and after being heated by steam generated in the first evaporation chamber 103, it is introduced into the first evaporation chamber 103 from the seawater supply port 115, where it is heated by the heater 105 as described above.

[0010] Patent Document 2: Japanese Utility Model Application Publication No. 60-124621 Summary of the Invention

[0011] The technical problem that the invention aims to solve

[0012] Recently, due to the miniaturization and increased efficiency of diesel engines, there is a tendency to reduce the waste heat of water jacketed cooling water. On the other hand, the water demand on ships tends to increase due to the strengthening of exhaust restriction measures. Therefore, there is a demand for highly efficient water production equipment.

[0013] However, the aforementioned existing multi-effect water production device 100 is multi-effect and seeks to achieve high efficiency, but it is a structure in which steam, which serves as the heat source for the first evaporation chamber 103, is introduced into the interior of the heat-conducting pipe 105a of the heater 105. Therefore, in order to ensure the required water production volume, there is a problem that the device is large-scale and its installation inside the ship becomes difficult.

[0014] Therefore, the object of the present invention is to provide a water production apparatus that improves water production efficiency.

[0015] Technical solutions for solving technical problems

[0016] The above-mentioned object of the present invention is achieved by the following water-making apparatus: a water-making apparatus comprising: a heater for heating a liquid to be treated to generate steam; and a condenser for condensing the steam generated by the heater, wherein the interior of the container body of the heater is divided by a partition plate to form a plurality of heating chambers, each of the heating chambers having a plurality of heat-conducting pipes, the liquid to be treated introduced into the interior of the heat-conducting pipes is heated by a heating fluid introduced into the outside of the heat-conducting pipes, warm water is introduced into the preceding heating chamber as a heating fluid, and the steam of the liquid to be treated generated in the preceding heating chamber by heating with warm water is introduced into the following heating chamber as a heating fluid (i.e., the steam of the liquid to be treated generated by introducing warm water as a heating fluid into the preceding heating chamber is introduced into the following heating chamber as a heating fluid).

[0017] In this water-making device, the heater preferably has a sealing plate that seals the opening of the container body, and a plurality of heat-conducting pipes are arranged to pass through the sealing plate. The sealing plate is detachably fixed to the end face of the partition plate via a gasket and a connector. This structure may also include a housing connected to the heater via the sealing plate and supporting the condenser. The housing is preferably internally divided by partition walls to form a plurality of gas-liquid separation chambers corresponding to each of the heating chambers. The partition walls are preferably arranged such that their end faces cover the connector via gaskets.

[0018] The heating chamber may include a reinforcing member that reinforces the partition plate from the inside, located on the rear-stage side of the heating chamber. Preferably, the reinforcing member is configured to divert the flow of heating fluid in the rear-stage heating chamber.

[0019] It may also include a retention section disposed on the outer peripheral surface of the container body. Preferably, the internal space of the retention section is connected to the heating chamber on the downstream side via a communication section formed in the side wall of the container body, and the heating fluid introduced into the retention section collides with the outer peripheral surface of the container body.

[0020] Preferably, the flow path of the heating fluid in the heating chamber formed in the subsequent stage gradually narrows from the upstream side to the downstream side.

[0021] In water production devices, achieving low cost while maintaining good purity of the generated condensate has become a challenge. As a solution to this challenge, a water production device can be provided, comprising: a heater for heating a liquid to be treated to generate steam; a housing having a demister for removing droplets contained in the steam generated by the heater; and a condenser for condensing the droplet-free steam, the demister being supported by a support member fixed to the heater or the condenser and housed within the housing.

[0022] In this water-making device, the support member preferably has a shape formed by bending or folding the strip-shaped component, supporting the demister at its edge in the width direction. More preferably, the support member is bent into a U-shape. The condenser can be arranged to penetrate the center of the interior of the housing. In this structure, the support members are preferably respectively disposed on both sides of the condenser.

[0038] Figure 13 This is a longitudinal section view of an existing water production device. Detailed Implementation

[0039] Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings. Figure 1 This is a longitudinal cross-sectional view of a water-making apparatus according to one embodiment of the present invention. The water-making apparatus 1 of this embodiment is a dual-effect type, including: a heater 10 for heating the liquid to be treated to generate steam; a housing 40 disposed on the upper part of the heater 10; and a condenser 50 supported in a manner that penetrates through the center of the interior of the housing 40 and whose central portion is housed inside the housing 40.

[0040] In the heater 10, the lower and upper openings of the cylindrical container body 11 are covered by the bottom plate 12 and the sealing plate 13, respectively, forming a sealed space inside. The interior of the container body 11 is divided by vertically extending partition plates 14 to form a first heating chamber 20 and a second heating chamber 30.

[0041] Multiple holes are formed in the base plate 12 and the sealing plate 13 respectively, and multiple heat conduction pipes 21 and 31 extending vertically through these holes are respectively disposed in the first heating chamber 20 and the second heating chamber 30.

[0042] The bottom plate 12 is connected to the seawater inlet 15 on its lower side. The seawater inlet 15 is formed in a disc shape and is divided internally by a partition plate 15a to form a first inlet chamber 15b and a second inlet chamber 15c. The first inlet chamber 15b and the second inlet chamber 15c are respectively connected to the lower ends of the heat-conducting pipes 21 and 31, and the treated liquid such as seawater introduced from the inlet ports 15d and 15e rises inside the heat-conducting pipes 21 and 31.

[0043] Supply ports 23 and 33 and discharge ports 24 and 34 are respectively formed on the side walls of the first heating chamber 20 and the second heating chamber 30. The heating fluid supplied from the supply ports 23 and 33 is discharged from the discharge ports 24 and 34 through the outside of the heat-conducting pipes 21 and 31. Baffles 25 and 35 are respectively provided inside the first heating chamber 20 and the second heating chamber 30 tortuously guide the flow path of the heating fluid. The baffles 25 and 35 are held at a predetermined height by cylindrical spacers (not shown) embedded in the heat-conducting pipes 21 and 31.

[0044] The housing 40 is a cylindrical component with a diameter larger than that of the heater 10. It has an opening 41 at the bottom and is covered by a cover plate at the top 42. The periphery of the opening 41 is connected to the periphery of the sealing plate 13 to seal the housing 40.

[0045] The interior of the housing 40 is divided by a partition wall comprising a lower partition wall 43 and an upper partition wall 44, forming a first gas-liquid separation chamber 60 and a second gas-liquid separation chamber 70. The first gas-liquid separation chamber 60 and the second gas-liquid separation chamber 70 include gas-liquid separation plates 61 and 71 disposed directly above the heat-conducting pipes 21 and 31, and demisters 62 and 72 disposed above the gas-liquid separation plates 61 and 71. The demisters 62 and 72 are known components formed by stacking mesh plates, and their lower surfaces are supported by support members 63 and 73 mounted on the condenser 50.

[0046] Vapor outlets 64 and 74 for discharging generated vapor are respectively formed in the upper parts of the first gas-water separation chamber 60 and the second gas-water separation chamber 70. In addition, drain outlets 65 and 75 for discharging liquid separated from vapor are respectively formed in the lower parts of the first gas-water separation chamber 60 and the second gas-water separation chamber 70.

[0047] The condenser 50 includes: a horizontally extending, channel-shaped receiving member 51 internally separated by an upper partition wall 44, comprising a guide groove made of a corrosion-resistant material such as stainless steel; and a plurality of heat-conducting pipes 52 housed along the receiving member 51 on both sides of the upper partition wall 44, and a preheater 55 containing the heat-conducting pipes 52 disposed on the side of the first gas-liquid separation chamber 60 of the upper partition wall 44. At both ends of the heat-conducting pipes 52, heads (not shown) are provided at positions protruding outward from the housing 40. Seawater or other treated liquid introduced into the condenser 50 is partially introduced into the first inlet chamber 15b via the preheater 55 through the inlet 15d, while the remainder is discharged as effluent.

[0048] In the water production device 1 with the above structure, the seawater, which is the liquid to be treated and supplied to the condenser 50, is preheated by the preheater 55 after the steam in the second gas-water separation chamber 70 is condensed and introduced into the first inlet chamber 15b, and then passes through the heat-conducting pipe 21 arranged in the first heating chamber 20.

[0049] For example, warm water that can be used on-site, such as the water jacket cooling water of a diesel engine installed on a ship, is supplied as a heating fluid from the supply port 23 into the first heating chamber 20 and discharged from the outlet 24 through the flow path formed by the baffle 25. As a result, the seawater passing through the heat pipe 21 is heated and evaporated in the heat pipe 21 and is introduced into the first gas-water separation chamber 60.

[0050] The steam introduced into the first gas-water separation chamber 60, after being separated from the mixed liquid droplets by the gas-water separation plate 61 and the demister 62, has a portion of the steam condensed by seawater passing through the heat pipe 52 of the preheater 55 and recovered as fresh water. The seawater separated from the steam in the first gas-water separation chamber 60 is discharged from the drain port 65 and introduced into the second inlet chamber 15c, passing through the heat pipe 31 configured in the second heating chamber 30.

[0051] The remaining vapor in the first gas-water separation chamber 60 is discharged from the outlet 64. After being supplied as a heating fluid to the supply port 33 of the second heating chamber 30, it is discharged from the outlet 34 through the flow path formed by the baffle 35 and is recycled as fresh water. Thus, the seawater passing through the heat pipe 31 is heated and evaporated in the heat pipe 31 and introduced into the second gas-water separation chamber 70.

[0052] The steam introduced into the second gas-water separation chamber 70 is separated from the mixed liquid droplets by the gas-water separation plate 71 and the demister 72. A portion of the steam is condensed in the condenser 50 by seawater passing through the heat pipe 52 and recovered as fresh water. The seawater separated from the steam in the second gas-water separation chamber 70 is discharged from the drain outlet 75 and recovered as brine. The remaining steam in the second gas-water separation chamber 70 is extracted by a vent (not shown) or similar device connected to the drain outlet 74.

[0053] The water production device 1 of this embodiment introduces the treated liquid, such as seawater, into the interior of the heat-conducting pipes 21 and 31 of the first heating chamber 20 and the second heating chamber 30, respectively, so that it evaporates inside the pipes. Furthermore, by introducing warm water as the heating fluid into the first heating chamber 20, condensate can be generated using low-temperature waste heat. Therefore, the water production device 1 can be miniaturized and made more efficient.

[0054] In the water-making apparatus 1 of this embodiment, the heating fluid for the first heating chamber 20 is warm water, while the heating fluid for the second heating chamber 30 is steam. Therefore, for example, the internal pressure of the first heating chamber 20 is 0.5 MPa, while the internal pressure of the second heating chamber 20 is -0.1 MPa, resulting in a larger pressure difference across the partition plate 14. Under such circumstances, when the sealing plate 13 is detachably installed on the container body 11, the partition plate 14 bends due to the internal pressure difference of the steam, thereby creating a gap between the sealing plate 13 and the partition plate 14. Through this gap, seawater enters the second heating chamber 30 from the first heating chamber 20, leading to a decrease in the purity of the steam introduced into the second heating chamber 30.

[0055] Therefore, in this embodiment, as Figure 2 As shown, a plurality of bolt holes 14a are formed at equal intervals on the upper end face of the partition plate 14 integrally formed on the container body 11. Together with the bolt holes 11a formed on the peripheral flange of the container body 11, the bolt holes 14a of the partition plate 14 are used for connection with the sealing plate 13, thereby eliminating the aforementioned problem, i.e., as shown. Figure 3 As shown, bolt holes 13a and 14a are formed in the sealing plate 13 and the partition plate 14, respectively. Using bolts or other connecting parts 16, the sealing plate 13 is fixed to the upper surface of the container body 11 and the partition plate 14 via gaskets 14b. As described above, the sealing plate 13 and the partition plate 14 can be detachably connected using the connecting parts 16, thereby maintaining good maintainability and reliably preventing gaps caused by deformation of the partition plate 14. Furthermore, the bottom plate 12 and the lower surface of the partition plate 14 can be integrally fixed by welding or the like, or detachably connected in the same way as the connection structure of the sealing plate 13 and the partition plate 14 described above.

[0056] like Figure 1 As shown, the lower partition wall 43, located inside the housing 40, is configured to hang down from the lower surface of the receiving component 51 of the condenser 50, and the lower end face of the lower partition wall 43 abuts against the upper surface of the sealing plate 13. Figure 3As shown, a gasket 43a is provided between the housing 40 and the lower partition wall 43 and the closing plate 13, and the connecting member 16, which is inserted into the bolt hole 13a of the closing plate 13, is covered by the lower end face of the lower partition wall 43. To prevent the connecting member 16 from protruding from the upper surface of the closing plate 13, the connecting member 16 is preferably a low-head bolt. With this structure, the connection between the closing plate 13 and the partition plate 14 using the connecting member 16 can be maintained more reliably.

[0057] Figure 4 This is a plan view of the housing 40, showing the state with the cover 42 removed. Additionally, Figure 5 This is a side view of the support member 63 installed on the receiving member 51. (See attached image.) Figure 4 and Figure 5 As shown, the housing 40 has multiple brackets 64 protruding horizontally into the first gas-liquid separation chamber 60 fixed to one side wall of the horizontally extending receiving member 51 by welding or the like. At both ends of the multiple brackets 64, a strip-shaped support member 63 is respectively mounted to the bracket 64 with screws 64a. The support member 63 is fixed with its width direction aligned vertically. The demister 62, with a shape and size occupying the entire space between the inner wall of the housing 40 and the side wall of the receiving member 51, is mounted on the width-direction edge of the curved support member 63 when viewed from above.

[0058] On the other side wall of the receiving component 51, a plurality of brackets 74 protruding horizontally toward the second gas-water separation chamber 70 are fixed by welding or the like. Similar to the support component 63, the two ends of the U-shaped strip support component 73 are respectively installed on the brackets 74.

[0059] As described above, the entire demisters 62 and 72 can be supported solely by the support members 63 and 73 installed on the condenser 50, thus eliminating the need for support members for the demisters 62 and 72 on the inner wall of the housing 40. Consequently, protrusions for supporting the demisters 62 and 72 are absent on the inner wall of the housing 40, thereby improving operational efficiency during assembly. The housing 40 is formed using inexpensive materials such as SS400, making it easy to apply a corrosion-resistant coating to the inner wall, achieving both low cost and durability.

[0060] Furthermore, the support members 63 and 73 are mounted on the condenser 50, thereby preventing the central side of the demisters 62 and 72 from falling off, and allowing the demisters 62 and 72 to be reliably supported by the support members 63 and 73. Moreover, the demisters 62 and 72 are linearly supported by the edges of the strip-shaped support members 63 and 73, thereby ensuring the steam passage area and providing stable support for the demisters 62 and 72. The support structure for the demisters 62 and 72 in this embodiment is particularly effective when the housing 40 is miniaturized and the installation space for the demisters 62 and 72 is limited.

[0061] From the viewpoint of reliably supporting the overall structure of the demisters 62 and 72, the shape of the support members 63 and 73 is preferably U-shaped as in this embodiment. However, it can also be bent or folded into various shapes such as polygons or waves.

[0062] Furthermore, the existing water-making device disclosed in Patent Document 2 uses a locking tab protruding from the inner wall of a sealed tank to support the periphery of the demister. This demister support structure utilizes inexpensive materials with low corrosion resistance to form the sealed tank. Therefore, a corrosion-resistant coating is required for the inner wall surface. However, completely coating the locking tab is time-consuming. Additionally, the locking tab becomes an obstacle during the installation of internal components, resulting in poor operability. Moreover, the demister is prone to falling off the opposite side of the inner wall of the sealed tank supported by the locking tab, making stable gas-liquid separation impossible and leading to a decrease in the purity of the condensate.

[0063] The above describes one embodiment of the present invention in detail, but the specific implementation of the present invention is not limited to the above embodiment. For example, in this embodiment, the partition plate 14 is strengthened by using the connecting member 16 to detachably fix the sealing plate 13 to the end face of the partition plate 14 through the gasket 14b. However, as... Figure 6 As shown, a reinforcing member 17 can be configured in the second heating chamber 30, which is on the low-pressure side relative to the first heating chamber 20 of the container body 11.

[0064] The reinforcing member 17 is a block-shaped component disposed between the inner wall of the container body 11 and the side of the partition plate 14, and multiple such components are arranged at intervals in the vertical direction. This structure also suppresses the expansion of the partition plate 14 towards the second heating chamber 30, preventing seawater from entering the second heating chamber 30. This reinforcing structure based on the reinforcing member 17 can also be used in combination with the aforementioned connecting structure of the sealing plate 13 and the partition plate 14 based on the connecting member 16.

[0065] In addition, in this embodiment, the partition plate 14 of the container body 11 is arranged in the vertical direction to divide the interior of the container body 11 into left and right. However, by arranging the partition plate 14 horizontally to divide the interior of the container body 11 into upper and lower sections, a first heating chamber 20 and a second heating chamber 30 can also be formed.

[0066] Furthermore, in this embodiment, a preheater 55 built into the condenser 50 is configured in the first gas-liquid separation chamber 60. However, as... Figure 7 As shown, the preheater 55 can also be configured in the second gas-liquid separation chamber 70. The liquid being processed supplied to the condenser 50 condenses the vapor in the second gas-liquid separation chamber 70, and a portion is preheated by the preheater 55 and introduced into the first inlet chamber 15b, while the remainder is discharged as drainage. Alternatively, as... Figure 8As shown, the preheater 55 can be configured with a first preheater 55a disposed in the first gas-liquid separation chamber 60 and a second preheater 55b disposed in the second gas-liquid separation chamber 70. The liquid to be processed supplied to the condenser 50 is condensed by the vapor in the second gas-liquid separation chamber 70. A portion of the liquid is preheated in the second preheater 55b and the first preheater 55a and then introduced into the first inlet chamber 15b. The remaining portion is discharged as drainage.

[0067] Furthermore, while the water production device 1 of this embodiment is a double-effect type, by dividing the container body 11 with multiple partitions to form three or more heating chambers, and using the steam generated in the first-stage heating chamber as the heating fluid for the subsequent-stage heating chamber, a multi-effect type with three or more stages can be formed. On the other hand, regarding the structure of supporting the demister with a support member fixed to the condenser, it can be a single-effect type without partitions. In either the single-effect or multi-effect type water production device, the support member 63 can be supported by the receiving member 51 of the condenser 50. The installation position of the support member 63 relative to the condenser 50 is not necessarily the receiving member 51 as in this embodiment; it can be any other position where the support member 63 can be installed.

[0068] The connection between the container body 11 and the sealing plate 13, in this embodiment, is as follows: Figure 2 As shown, bolts and other connecting parts are inserted into the peripheral flange of the container body 11 through a washer, forming multiple bolt holes 11a. However, as... Figure 9 As shown, by forming a welded portion W1 using fillet welding around the outer circumference of the cylindrical end of the container body 11, the container body 11 and the sealing plate 13 can be connected. The connection between the container body 11 and the bottom plate 12 can also be achieved by forming a welded portion W2 around the outer circumference of the cylindrical end of the container body 11. In this case, the connection between the bottom plate 12 and the sealing plate 13 and the partition plate 14 can be achieved using a gasket-type connector, similar to this embodiment. Alternatively, as... Figure 10 As shown in (a), by forming welding portions W3 and W4 on both sides of the partition plate 14 in the thickness direction, the closing plate 13 (or the bottom plate 12) and the partition plate 14 can be connected. Furthermore, as... Figure 10 As shown in (b), a through hole 13b is formed in the sealing plate 13 (or the base plate 12), and a welded portion W5 is formed in the through hole 13b, thereby enabling the sealing plate 13 (or the base plate 12) and the partition plate 14 to be connected. The through hole 13b formed in the sealing plate 13 is preferably formed at a position closed by a gasket 43a provided between the lower partition wall 43 and the sealing plate 13.

[0069] The heating fluid, mainly formed from steam, is introduced at high speed into the supply port 33 of the second heating chamber 30. A retention section with a collision plate that the introduced heating fluid collides with is provided between the supply port 33 and the second heating chamber 30, thereby improving the heat exchange efficiency of the heat pipe 31. However, in this structure, the supply port 33 protrudes significantly outward from the heater 10, resulting in the problem of a large-scale water production device 1. Therefore, as... Figure 11 As shown, a retention portion 18, fixed by welding or the like, is preferably provided on the outer peripheral surface of the container body 11. The internal space of the retention portion 18 is connected to the second heating chamber 30 via a connecting portion 18a formed in the side wall of the container body 11. When heating fluid is introduced into the retention portion 18 from the supply port 33, the heating fluid collides with the outer peripheral surface of the container body 11. According to this structure, the outer peripheral surface of the container body 11 acts as the aforementioned collision plate. Therefore, it is not necessary to re-install a collision plate in the retention portion 18, and the structure of the water making device 1 can be compactly maintained. The collision point of the heating fluid in the outer peripheral surface of the container body 11 is not particularly limited, but it is preferably below the connecting portion 18a.

[0070] Figure 11 It is along Figure 9 AA section representation Figure 9 The diagram shows a cross-sectional view of a modified example of the heater 10. The heating fluid introduced into the second heating chamber 30 from the supply port 33 flows in a tortuous manner along the partition plate 14 due to the upper and lower baffles 35, and is discharged from the outlet 34. The spacing S1 between the sealing plate 13 and the upper baffle 35, the spacing S2 between the upper and lower baffles 35, and the spacing 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; however, the heating fluid introduced from the supply port 33 gradually condenses inside the second heating chamber 30, therefore, compared with… Figure 11 Similarly, the configuration shown allows for efficient heating of the entire heat pipe 31 by making the flow path of the heating fluid formed in the second heating chamber 30 by the sealing plate 13, multiple baffles 35 and the bottom plate 12 gradually narrow from the upstream side to the downstream side.

[0071] The baffle installed in the second heating chamber 30 can also be used as Figure 6 The reinforcing component 17 is shown. That is, as shown... Figure 12As shown, gaps 17a and 17b are formed between the reinforcing member 17 and the closing plate 13 and the base plate 12, respectively, thereby dividing the flow of the heating fluid into upper and lower portions of the reinforcing member 17. By enabling the reinforcing member 17 to function as a baffle in this way, it is not necessary to replace the baffle, thus reducing assembly work. The flow of the heating fluid based on the reinforcing member 17 can be divided by forming gaps on the left and right sides of the reinforcing member 17, or by forming multiple openings or cuts in the reinforcing member 17.

[0072] Regarding the structure of supporting the demister with support members, in this embodiment, support members 63 and 73 are fixed to the portion of the condenser 50 housed inside the housing 40. However, support members 63 and 73 can also be fixed to a portion outside the inner wall surface of the housing 40. The heater 10 or condenser 50 can be housed at least partially inside the housing 40, and support members 63 and 73 can be fixed to the portion of the heater 10 or condenser 50 housed inside the housing 40 to support the demisters 62 and 72. For example, the length can be extended... Figure 1 The upper part of the heater 10 shown is housed inside the housing 40, and the support members 63 and 73 are fixedly extended upward from the outer wall of the housed part.
