Description

The present invention relates to a distillation device that is easy to install.

Traditionally, distillation equipment (plants) are individually designed based on various factors, such as the chemical properties and temperature characteristics of the material to be distilled in the distillation equipment, the distillation precision required for the distillation equipment, the time required to obtain the distilled and purified product, the yield of the distilled and purified product, and the amount of material to be distilled that can be distilled per unit time. The volume of the still, the length and outer diameter of the gas-liquid contact section and condenser section, etc. are then constructed and completed at the desired installation location.

However, because the height of a distillation apparatus (plant) can range from several meters to several tens of meters, construction requires unavoidable work at height, and the distillation apparatus structure must be assembled and the distillation furnace, gas-liquid contact section, and condenser section must be installed while ensuring the safety of the workers. This poses technical challenges, requiring a high level of specialized knowledge and skill, and taking an extremely long time from design and construction to completion and operation, and inevitably resulting in high manufacturing costs.

The applicant has already proposed a precision distillation and purification apparatus as disclosed in Patent Document 1, etc.

Below, an embodiment of the present invention will be described with reference to the drawings.

[Embodiment 1]
Figures 1 to 3 are schematic diagrams showing the overall configuration of a batch-type distillation apparatus according to embodiment 1 of the present invention, where Figure 1 is a front structural view of the distillation apparatus, Figure 2 is a side structural view of the distillation apparatus, and Figure 3 is a perspective structural view of the distillation apparatus.

As shown in Figures 1 to 3, the distillation apparatus 1 according to this embodiment 1 is configured to support a distillation tower, which is an example of a distillation means, with a support structure 2 made of a steel frame or the like within the premises of a factory or the like where it is to be installed. However, the distillation apparatus 1 according to this embodiment 1 is not constructed and installed within the premises of a factory or the like where it is to be installed, but is manufactured in a dedicated manufacturing plant for manufacturing the distillation apparatus 1, which is separate from the installation site, and is then transported by a transportation means such as a trailer and installed (laid down) within the premises of the factory where it is to be installed.

As shown in Figures 1 to 3, the distillation apparatus 1 according to the first embodiment is configured by arranging a plurality of (three in the illustrated example) distillation apparatuses 1 ₁ to 1 ₃ in one direction, and integrally connecting adjacent distillation apparatuses 1 ₁ to 1 ₃ to each other. In addition, at one end (the right end in the figure) along the arrangement direction of the distillation apparatuses 1 ₁ to 1 ₃ , a support structure 2 ₄ formed to the same size as the distillation apparatuses 1 ₁ to 1 ₃ and equipped with a staircase for workers to ascend and descend is integrally connected adjacently. Note that the distillation apparatus 1 is not limited to one equipped with a plurality of distillation apparatuses 1 ₁ to 1 ₃ , and may of course be one consisting of a single distillation apparatus 1.

Each of the distillation apparatuses 1 ₁ to 1 ₃ has the same configuration. The support structure 2 of each of the distillation apparatuses 1 ₁ to 1 ₃ is set to a size equivalent to that of a container conforming to the ISO standard. The support structure 2 according to the present embodiment 1 is, for example, in accordance with a 40-foot container conforming to the ISO standard.

The International Organization for Standardization (ISO) has standardized containers to standardize transportation infrastructure and ensure efficient transportation operations, and ISO-standardized containers have the same external dimensions (outer dimensions) regardless of the manufacturer that produced the container. ISO-standardized containers are available in multiple sizes, such as 20 feet and 40 feet. The support structure 2 in this embodiment 1 may have external dimensions equivalent to those of a container that complies with the ISO standard.

The external dimensions of the support structure 2 are set to the same as a 40-foot container, with a length L of 2591 mm, a width W of 2438 mm, and a height H of 12192 mm. Note that the support structure 2 is not limited to one that complies with the 40-foot standard, and may be one that complies with other standards such as 20 feet. Furthermore, the support structure 2 may be one that complies with JIS standards in addition to ISO standards, and may be one that does not necessarily comply with ISO or JIS standards, as long as it can be transported by a transportation means such as a trailer.

As shown in FIG. 4, the support structure 2 includes four support members 3-6 arranged at each corner of a rectangular area in a planar state in a vertically upright state, vertical beam members 7, 8 connecting the support members 3, 5 and support members 4, 6 adjacent to each other along the vertical direction in the horizontal plane among the four support members 3-6, and horizontal beam members 9, 10 connecting the support members 3, 4 and support members 5, 6 adjacent to each other along the horizontal direction in the horizontal plane among the four support members 3-6. For example, H-shaped steel 11 having an H-shaped cross section is used as the support members 3-6, the vertical beam members 7, 8, and the horizontal beam members 9, 10. As is well known, the H-shaped steel 11 is a shaped steel formed into an H-shaped cross section by integrally connecting two flat flanges 12, 13 arranged parallel to each other at the center along the width direction with a flat web 14, as shown in FIG. 5.

However, these support members 3 to 6, vertical beam members 7, 8, and horizontal beam members 9, 10 are not limited to being made of H-shaped steel, but may be made of steel material formed into a square tube shape with a rectangular cross section (column frame) or L-shaped steel.

Each of the support members 3 to 6 may be either one divided into a plurality of members along the longitudinal direction with a total length of 12192 mm in accordance with an ISO standard 40-foot container, or one consisting of a single member set to a total length of 12192 mm. In this embodiment 1, each of the support members 3 to 6 is divided into a plurality of members (five in the illustrated example) 3 ₁ to 3 ₅ , 4 ₁ to 4 ₅ , 5 ₁ to ₅ , 6 ₁ to 6 ₅ along the longitudinal direction (height direction).

The four support members 3-6 are arranged vertically and horizontally at intervals (distances) of 2591 mm vertically and 2438 mm horizontally, in accordance with the ISO standard for 40-foot containers. The vertical beam members 7, 8 that connect the four support members 3-6 vertically in the horizontal plane are each set to a vertical length corresponding to 2591 mm vertically, in accordance with the ISO standard for 40-foot containers. The horizontal beam members 9, 10 that connect the four support members 3-6 horizontally in the horizontal plane are each set to a horizontal length corresponding to 2438 mm horizontally (including the length of the connection with the vertical beam members 7, 8), in accordance with the ISO standard for 40-foot containers.

The H-shaped steel 11 used as the support members 3 to 6 is arranged, for example, so that the two flanges 12, 13 are positioned vertically and the web 14 is positioned horizontally. By arranging the H-shaped steel 11 in this manner, it is possible to connect adjacent support structures 2 to each other by fastening the flanges 12, 13 of the H-shaped steel 11 of adjacent support structures 2 to each other with bolts 15 and nuts 16, as shown in Figure 6.

When column frames 17 made of rectangular columns with a rectangular cross section, as shown in FIG. 7, are used as the steel material that makes up the support members 3 to 6, it is necessary to provide hand holes 18, which are openings for fastening the bolts 15 and nuts 16, when connecting the column frames 17 together. This reduces the strength of the columns, and allows rainwater and other liquids to get in through the storage lid (not shown) that closes the hand holes 18, causing corrosion.

The H-shaped steel 11 used as the vertical beam members 7, 8 and the horizontal beam members 9, 10 is arranged, for example, so that the two flanges 12, 13 are positioned along the horizontal direction and the web 14 is positioned along the vertical direction, as shown in Figure 5.

The four support members 3 to 6, the vertical beam members 7 and 8, and the horizontal beam members 9 and 10 are joined together by means of welding, bolting, or other methods to form the support structure 2.

As shown in FIG. 4, the support structure 2 is provided with partition members 20-24 that partition the support structure 3 at predetermined lengths along its longitudinal direction (height direction) in a direction intersecting the longitudinal direction. The partition members 20-24 are formed by appropriately laying a single steel plate or a steel material formed into a U-shaped cross section. As a result, the support structure 2 is divided into a plurality of layers (floors) along its longitudinal direction (height direction) by the partition members 20-24. For convenience, the first layer of the support structure 2 will be called the first floor, the second layer will be called the second floor, and so on, according to the number of floors of the building. In the illustrated embodiment 1, the support structure 2 has the first to fifth floors, with the fifth floor being the top floor. The partition members 20-24 of each floor form the ceiling of the lower floor and also serve as the floor of the upper floor. At this time, the partition member 20 on the first floor constitutes the floor of the first floor, and the partition member 24 on the fifth floor constitutes the ceiling of the fourth floor and the floor of the fifth floor.

As shown in Figures 1 and 2, the upper and lower ends of _{the support members 31-35, 41-45 , 51-55 , and 61-65} on each floor of the support structure 2 are connected to each other by diagonally arranged bracing members 25, ₂₆ made of reinforcing bars or the like. Both ends of _the bracing members 25, 26 are fixed by means of welding or bolt fastening to small rectangular connecting plates ₂₇ , 28 attached by means of welding or the like to the corners _of the support members _31-35 , _41-45 , _51-55 , and _61-65 located on the floor and ceiling _of each _floor . The bracing members 25, 26 arranged on each floor are arranged so that their orientations are alternated. It is to be noted that the bracing members 25, 26 arranged on each floor are not limited to one, and two bracing members may be arranged so as to cross each other as necessary.

In the support structure 2 according to the first embodiment, the height of the first floor (first layer) is 2550 mm, the heights of the second floor (second layer) to the fourth floor (fourth layer) are 2400 mm, and the height of the fifth floor (fifth layer) is 2442 mm. The heights of the layers may all be set to the same height or may all be set to different heights.

In the support structure 2 according to the first embodiment, as described below, the distillation pot 51, which is one of the distillation means, is placed on the first floor, which is the first layer, and its height is set to a relatively high 2,550 mm in consideration of the ease of operation of workers.

The support structure 2 according to the first embodiment is installed as follows within the premises of a factory or the like, which is the installation site where the distillation apparatuses 1 ₁ to 1 ₃ are installed.

First, on site 30 of a factory or the like where the devices are to be installed, concrete 32 is poured over a predetermined area and to a predetermined thickness in area ₃₁ in which distillation apparatuses _1-1-1-3 are to be installed, as shown in Fig. 8. Also, in installation area 31, leakage prevention wall 33 is provided over a predetermined height so as to surround installation area 31 in preparation for leakage of chemicals, as shown in Fig. 2. Also, a water tank 33a consisting of a planar rectangular area surrounded by leakage prevention wall 33 and for storing water is provided in part of leakage prevention wall 33.

In the installation area 31 where concrete 32 has been poured, as shown in Figures 9 and 10, two anchor bolts 34, 35 are embedded in the concrete 32 at both ends along the longitudinal direction of the cross beam members 9, 10 located on the bottom surface of the support structure 2, so as to be located on both sides along a direction intersecting the cross beam members 9, 10.

As shown in FIG. 9, the support structure 2 is installed in the installation area 31 in a state where it is suspended by a crane or the like so that the cross beam members 9, 10, which are an example of a structure located on the bottom surface of the support structure 2, are located between the two anchor bolts 34, 35. A base plate 37, which is an example of a plate-like member, is arranged on the cross beam members 9, 10 located on the bottom surface of the support structure 2 so as to intersect with the cross beam members 9, 10 and to cover the outer peripheral surfaces of the cross beam members 9, 10.

As shown in FIG. 10, the base plate 37 is formed by bending a steel plate into a U-shaped cross section to cover the outer peripheral surfaces of the cross beam members 9, 10, and bending both ends of the steel plate so that they extend horizontally. Both side walls 38, 39 of the base plate 37 are connected to the bottom walls 40, 41 extending horizontally by reinforcing plate parts 42, 43 with approximately triangular sides arranged at both ends along the width direction of the base plate 37. The bottom walls 40, 41 of the base plate 37 have insertion holes at positions corresponding to the two anchor bolts 34, 35 embedded in the installation area 31.

As shown in FIG. 9, the support structure 2 is placed upright at a predetermined position in the installation area 31, and the outer peripheral surfaces of the cross beam members 9, 10 located at the bottom are covered by the base plate 37. The bottom walls 40, 41 of the base plate 37 are inserted into two anchor bolts 34, 35, respectively, and fastened and fixed by nuts 34a, 35a (see FIG. 10). In addition, the cross beam members 9, 10 and the base plate 37 are connected and fixed by fastening the flanges 12 with bolts 44 and nuts 45, as shown in FIG. 10.

In the illustrated embodiment, only the horizontal beam members 9 and 10 of the support structure 2 are fastened and fixed by the base plate 37, but the vertical beam members 7 and 8 of the support structure 2 may also be fastened and fixed by the base plate 37.

As shown in Figures 1 and 2, before the support structure 2 configured as described above is installed in the installation area 31 of a factory or the like, a distillation tower 50 as an example of a distillation means for distilling the object to be distilled at the manufacturing plant of the distillation apparatus 1 is attached along the longitudinal direction of the support structure 2 with a strength sufficient to withstand lateral loads during transportation.

As shown in FIG. 11, the distillation apparatus 1 according to the first embodiment includes, as components constituting a distillation tower 50, a batch-type distillation still kettle 51 that contains the material to be distilled, a long gas-liquid separation section (packed tower) 52 that is continuous with the upper part of the distillation still kettle 51, a distribution section 53 that is continuous with the upper end of the gas-liquid separation section 52 and distributes the distilled and purified product, a condenser (heat exchanger) section 54 that is continuous with the upper end of the distribution section 53 and is arranged horizontally, and one or more receivers 55-57 (see FIG. 19) that contain the distilled and purified product distributed by the distribution section 53.

As shown in FIG. 11, the distillation kettle 51 is a hollow cylindrical member with a round bottom, made of titanium, nickel, or a metal with excellent thermal conductivity such as stainless steel or copper, which contains the object to be distilled. The distillation kettle 51 has a built-in spiral heating tube 58 that heats the object to be distilled by passing heating steam or the like as a heat source supplied from the outside. The outer wall of the distillation kettle 51 has a double structure with a hollow space 59. The hollow space 59 of the distillation kettle 51 is configured to be supplied with heating steam from the outside, so that the distillation kettle 51 is heated from the outside. However, the heating means for heating the distillation kettle 51 is not limited to heating steam or the like supplied from the outside through the heating tube 58 or the hollow space 59, and any means capable of heating the distillation kettle 51 may be used. For example, if the distillation kettle 51 is made of a material that can be heated by electromagnetic induction, the distillation kettle 51 may be heated by electromagnetic induction or the like.

The distillation kettle 51 used has a capacity of, for example, 400 L. However, the capacity of the distillation kettle 51 is not limited to 400 L, and it can of course be larger or smaller than this.

The distillation kettle 51 has a relatively large capacity and is made of a metal such as titanium or stainless steel, so it is the heaviest member of the distillation means. When assembling and manufacturing the distillation apparatus 1 at a manufacturing factory, the distillation kettle 51 must be attached to the support structure 2 with a strength sufficient to withstand lateral loads caused by lateral shaking during transportation.

In this embodiment 1, as shown in FIG. 12, the distillation kettle 51 is provided with an attachment member 510 consisting of a flange or the like, either integrally or separately, on its outer circumferential surface. The distillation kettle 51 is attached to the partition member 21 on the second floor of the support structure 2 via the attachment member 510 by means of fastening using bolts 512a and nuts 512b or other means, in a fixed state with a strength sufficient to withstand lateral loads during transportation.

The distillation kettle 51 is supported in a suspended state by a steel support wire 514 via a hook portion 513 provided at its upper end, as necessary. The upper end of the support wire 514 is connected to the support member 3 of the support structure 2 or the partition member 22, etc.

As shown in Figures 13 and 14, the distillation kettle 51 is not connected to the center of the flat rectangular support structure 2, but is connected at a position offset toward one end of the support structure. The distillation kettle 51 is located close to one of the four support members 3 to 6, and is spaced equally apart from the vertical and horizontal beam members. In addition, an opening 511 for sending the vaporized material to be distilled to the distillation tower is opened at the top of the distillation kettle 51, not at the center of the flat circular distillation kettle 51, but at a position offset toward one of the support members 3.

As shown in FIG. 11, a gas-liquid separation section (packed tower) 52 is fixed in a connected state to the upper end of the distillation kettle 51. The gas-liquid separation section (packed tower) 52 is connected to an opening 511 that is opened not at the center of the distillation kettle 51, but at a position offset from the center toward one of the support members 3. Therefore, as shown in FIGS. 15 to 18, the gas-liquid separation section (packed tower) 52 is arranged along the support members 3 at positions close to the support members 3 from the second to fifth floors of the support structure 2. The gas-liquid separation section (packed tower) 52 is fixed by inserting its intermediate position into an insertion hole provided in a partition member of the support structure 2, and is attached with a strength sufficient to withstand lateral loads during transportation.

A relatively short distribution section 53 and a condenser (heat exchanger) section 54 are connected in sequence to the top of the gas-liquid separation section (packed tower) 52. The condenser (heat exchanger) section 54 is arranged in a horizontally folded state on the top floor of the support structure 2.

To explain further, the condenser (heat exchanger) section 54 is arranged diagonally from the support member 3 to the support member 6 on the top floor of the support structure 2. As a result, it is possible to arrange the condenser (heat exchanger) section 54 inside the support structure 2, which has a limited height, without unnecessarily increasing the area of the installation surface of the support structure 2.

The multiple receivers 55-57 are attached to the support structure 2 with their upper ends fixed to a partition member on the second floor of the support structure 2 and their lower ends fixed to a partition member, providing them with the strength to withstand lateral loads during transportation.

The multiple receivers 55-57 are each connected to the distribution section 53 via a double pipe 58a that constitutes a product extraction line. The double pipe 58a that constitutes the product extraction line is branched at its lower end and communicates with each of the receivers 55-57 individually. Each of the receivers 55-57 is also configured to communicate with the distribution section 53 individually via multiple valves 59a-61 that are provided on each of the branched double pipes 58a. Hot water at a required temperature is supplied to the external pipe of the double pipe 58a from a hot water facility described below.

Figure 19 is a diagram showing the piping system of the distillation apparatus according to the first embodiment.

The distillation apparatus 1 according to the first embodiment includes a distillation kettle 51, as shown in FIG. 19. At the top of the distillation kettle 51, as shown in FIG. 11, an inlet 62 is opened for introducing the material to be distilled into the distillation kettle 51, and a pressure gauge 63 is attached to detect the pressure inside the distillation kettle 51. A supply pipe 64 with valves at both ends is connected to the inlet 62 of the distillation kettle 51. At the tip of the supply pipe 64, a raw material suction port 65 is provided, as shown in FIG. 19.

In addition, a pipe 67 is connected to the top of the distillation kettle 51, which leads to a bottom manometer 66 that detects the pressure difference inside the distillation kettle 51, which is located at the lowest part (bottom) of the distillation tower 50, and a hot water return line 68 that returns the hot water inside the distillation kettle 51 is connected along the pipe 67.

In addition, a residue outlet 69 is opened at the bottom of the distillation kettle 51 to remove the residue remaining inside the distillation kettle 51 after the distillation process is completed. Also at the bottom of the distillation kettle 51, a first temperature sensor 70 is disposed to detect the temperature at the bottom of the distillation kettle 51.

The packed tower 52, which is arranged so as to be continuous with the top of the distillation still kettle 51, is provided with second to fifth temperature sensors 71 to 74, which detect the temperature of the packed tower at predetermined heights.

The distributor 53 is connected to a product outflow line 58a consisting of a double pipe that stores the distillation product distilled by passing through the packed tower 52 in a receiver. The ends of the product outflow line 58a are connected to each of the receivers 55 to 57. A sixth temperature sensor 75 is disposed in the distributor 53 to detect the temperature of the distributor 53.

At the bottom of each receiver 76-78, a product outlet 76-78 is opened, respectively, for removing the distillation product as the product. In addition, the outer wall of each receiver 55-57, which is formed in a double structure, is configured so that hot water is supplied from a hot water facility.

In addition, a pipe 81 is connected to the upper end of the distributor 53, which leads to a top manometer 80 that detects the pressure difference inside the distributor 53 located at the top (top) of the distillation tower 50, and a seventh temperature sensor 82 is installed to detect the temperature of the upper end of the distributor 53.

The condenser section 54 is also provided with a cooling water inlet 83 and a cooling water outlet 84. A pipe 86 leading to the vacuum units 95-97 is connected to the upper end of the condenser section 54, and an eighth temperature sensor 87 is disposed to detect the temperature of the upper end of the condenser section 54.

As shown in FIG. 14, the auxiliary equipment of the distillation apparatus 1 includes boiler equipment _91-93 which supplies heated steam to the distillation kettles ₅₁ of each of the distillation apparatuses _1-13 , cooling water equipment ₉₄ which supplies cooling water to the condenser sections 54 of each of the distillation apparatuses _1-13 , vacuum pump units 95-97 connected to the condenser sections ₅₄ of each of the distillation apparatuses _1-13 , and a compressor 98 which supplies compressed air to each of the distillation apparatuses _1-13 .

These auxiliary equipment of the distillation apparatus 1 may be arranged individually at the installation location of the distillation apparatus 1, as shown in Figure 14, or may be arranged together inside a support structure 25 arranged horizontally and configured in the same manner as the support structure ₂ , as shown in Figure 3.

<Function of the distillation apparatus>
In the distillation apparatus of this embodiment 1, the characteristics of the apparatus mean that the apparatus must be a tall structure along the vertical direction, but the distillation apparatus is assembled by attaching components along the height direction to the tall structure, and it is possible to install and operate the distillation apparatus safely, easily, and at a desired location in a shorter period of time and at lower cost than in the past, as described below.

In other words, the distillation apparatus 1 according to this embodiment 1 is designed with the capacity of the distillation still kettle 51, the outer diameter and height of the distillation tower 50, the capacity and number of receivers 55 to 57, etc., determined in advance before being installed on the premises of a factory or the like (not shown), as shown in FIG. 19.

The distillation apparatus 1 according to the first embodiment is assembled and manufactured in a factory that manufactures the distillation apparatus 1, using a support structure 2 of a size conforming to an ISO standard container as a base, as shown in Figures 1 to 3.

As shown in Figures 1 to 4, the support structure 2 is assembled as a long rectangular parallelepiped frame by connecting pillar members 3 to 6, vertical beam members 7, 8, and horizontal beam members 9, 10, which are made of H-shaped steel 11, by means of welding or other means. Partition members 20 to 24 are arranged on the floor surface of each floor of the support structure 2 to separate it. In addition, the pillar members 3 to 6 on each floor of the support structure 2 are connected to each other by diagonal bracing members to improve their strength.

Next, as shown in Figures 1 to 4, the distillation pot 51, gas-liquid separation section (packed tower) 52, distribution section 53, condenser (heat exchanger) section 54, and multiple receivers 55 to 57 that make up the distillation apparatus 1 are attached in sequence to the support structure 2 assembled as described above with a strength sufficient to withstand lateral loads during transportation, and the distillation apparatus 1 is assembled and manufactured.

The auxiliary equipment of the distillation apparatus 1 does not require work at height and may be installed individually on-site, but is assembled by arranging them all together inside a support structure ₂₅ that is configured in the same way as the support structure 2 and arranged horizontally.

The distillation apparatus 1, which has been preassembled and manufactured in a factory dedicated to distillation apparatus as described above, is placed on the bed of a trailer 100 and secured thereto using a crane or the like (not shown) as shown in FIG. 20, and is then transported to the factory where the distillation apparatus 1 will be installed.

The distillation apparatus 1 is transported to the site of a factory or the like where it is to be installed, and is suspended by a crane or the like (not shown) at the installation site where concrete has already been poured, as shown in Figures 8 to 10, and the support structure 2 is raised and the cross beam members 7 and 8 of the support structure 2 are positioned at the installation site.

Thereafter, the cross beam members 7, 8 of the support structure 2 are fixed to the installation location by fastening the anchor bolts with nuts via the base plate. The support structures 2 of adjacent distillation apparatuses 1 are connected to each other. A support structure 24, which is configured in the same way as the support structure 2 and has a spiral staircase attached thereto for workers to ascend and descend, is connected and fixed to the support structure ₂ of the distillation apparatus 1 located at the end.

Furthermore, the distillation apparatus 1 is completed by connecting the necessary piping, etc. to each component of the distillation tower 50 attached to the support structure 2, and by connecting various wiring.

In this way, the distillation apparatus 1 according to the first embodiment must be a structure equipped with a tall support structure 2 along the vertical direction due to the characteristics of the apparatus, and the distillation apparatus 1 is assembled by attaching the distillation tower 50 along the height direction to the support structure 2. This makes it possible to install and operate the distillation apparatus 1 safely and easily in a desired location in a shorter period of time and at a lower cost than in the past, without having to perform on-site assembly work at a high altitude.

In the above embodiment, a batch-type distillation apparatus is described as the distillation apparatus, but the present invention is not limited to this, and can of course be applied to a continuous distillation apparatus as well.
