Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fluidized bed apparatus. In particular, the present invention relates to a fluidized bed apparatus suitable when the internal pressure becomes high.
[0002]
[Prior art]
As an apparatus for heating or cooling an object to be processed such as resin, lysine, salt, coal, or the like and drying along with these, there is an apparatus 101 as shown in FIG. The apparatus 101 has a main body 102 having a cubic shape or a rectangular parallelepiped shape to which the workpiece P is supplied, and a dispersion plate 103 installed in the main body 102, and a flowing gas blown up through the dispersion plate 103. The workpiece P is fluidized by G. In this apparatus 101, by disposing a panel-type heat exchanger (not shown) in the flow region 104 where the workpiece P is fluidized, or by increasing or decreasing the temperature of the flowing gas G, the workpiece P The product is heated, cooled (product temperature adjustment), or dried.
[0003]
However, this conventional fluidized bed apparatus 101 is not suitable for a high pressure specification (withstand pressure structure). That is, in the upstream process of the fluidized bed apparatus 101, when the workpiece P is processed in a high pressure atmosphere (for example, reaction process), the high pressure gas flows into the fluidized bed apparatus 101 (main body 102). Therefore, it is necessary to make the fluidized bed apparatus 101 have a high pressure specification. This is the same even if the processing apparatus and the fluidized bed apparatus 101 are separated by a damper or the like. However, in the conventional fluidized bed apparatus 101, as shown in FIG. 1, since the main body 102 has a cubic or rectangular parallelepiped shape, when the high pressure specification is used, the main body 102 is reinforced to the wall of the main body 102. The auxiliary material (not shown) must be attached, or the main body 102 itself must have high strength. Therefore, the equipment cost has increased. In addition, when an auxiliary material is attached in the main body 102 (flow region 104), the effective space in the main body 102 becomes narrow, and installation and inspection of the panel heat exchanger become very difficult.
[0004]
Therefore, when the fluidized bed apparatus is of a high pressure specification, as shown in FIG. 2, the shape of the main body 102 is a vertical cylindrical shape whose axial direction is the vertical direction (see, for example, Patent Document 1).
[Patent Document 1]
Japanese Patent Laid-Open No. 5-15900 (FIG. 1)
[0005]
[Problems to be solved by the invention]
However, if the shape of the main body is a vertical cylindrical shape, when installing a panel type heat exchanger, as shown in FIG. 2 (3), the panel type heat exchanger 105A near the center, and the panel types on both sides thereof. The shape must be sequentially changed with the heat exchanger 105B and the panel heat exchangers 105C on both sides thereof. The need for panel-type heat exchangers with various shapes leads to an increase in design costs as well as equipment costs. Of course, it is also conceivable to design all panel heat exchangers in accordance with the shape of the panel heat exchanger 105Z at both ends, but in that case, the heat transfer area is reduced, and the workpiece P is sufficiently heated or cooled. You may not be able to do it.
[0006]
Therefore, the main problem of the present invention is a fluidized bed apparatus in which a panel heat exchanger can be installed so that the object to be processed can be sufficiently heated or cooled while being a high pressure specification. Is to provide.
[0007]
[Means for Solving the Problems]
The present invention that has solved the above problems is as follows.

The dispersion plate is installed below the axial center position of the main body,
A flat plate extending upward from both side edges along the axial direction of the main body of the dispersion plate is provided in the main body .
A fluidized bed apparatus.
[0008]
(Function and effect)
Since the main body to which the object to be processed is supplied is cylindrical, the high pressure specification is obtained.
Further, the main body is a horizontal type whose axial direction is the horizontal direction, and the panel heat exchanger is installed so that its panel surface is orthogonal to the axial center of the main body. ), The plurality of panel heat exchangers 5, 5... Can all have the same outer dimensions. Therefore, the fluidized bed apparatus can be economically and sufficiently heated or cooled.
[0009]
[0010]
(Function and effect)
Since the dispersion plate is disposed below the position of the main body axis, it is possible to sufficiently secure a flow region for fluidizing the workpiece. Therefore, the residence time of the object to be processed can be sufficiently secured, and the panel heat exchanger installed in the flow region can have a large area.
[0011]
[0012]
(Function and effect)
When the main body has a rectangular parallelepiped shape or a vertical cylindrical shape as in the conventional apparatus, the cross-sectional area of the fluidized region 104 is as shown in each of (2) of FIG. 1 and FIG. It was constant. Accordingly, the superficial velocity is also constant (note that the superficial velocity can be slightly changed by increasing or decreasing the volume based on the temperature change or pressure change of the flowing gas, or by increasing the volume due to evaporation of the liquid component). There was no particular need to consider. However, when the main body has a horizontal cylindrical shape as in the apparatus of the present invention, the cross-sectional area of the flow region changes in the vertical direction. That is, the cross-sectional area increases sequentially from the lower end to the axial center position, and the cross-sectional area decreases sequentially from the axial center position to the upper end. Therefore, the superficial velocity changes, and it is necessary to make a complicated consideration about the flow state.
However, since the apparatus of the present invention is provided with flat plates extending upward from both side edges of the dispersion plate, the horizontal direction of the flow region in the vertical direction (meaning “anywhere in the vertical direction”). The cross-sectional area is constant (the same as the area of the dispersion plate). Therefore, the superficial velocity is constant, and there is no need for complicated considerations regarding the flow state.
[0013]
<Invention of Claim 2 >
The bottom region surrounded by the main body peripheral wall and the dispersion plate and the side region surrounded by the main body peripheral wall and the flat plate are in communication with each other, and the pressure in this side region and the pressure in the flow region where the workpiece is fluidized are substantially equal. The fluidized bed apparatus according to claim 1 , wherein the fluidized bed apparatus is made equal to each other.
[0014]
(Function and effect)
Since the bottom region surrounded by the main body peripheral wall and the dispersion plate and the side region surrounded by the main body peripheral wall and the flat plate are in communication with each other, the pressure in this side region and the pressure in the flow region where the workpiece is fluidized are Substantially equal. Therefore, when the flow region becomes high pressure, the side region also becomes high pressure, and pressure is not applied only in one direction (direction from the flow region to the side region) with respect to the flat plate. There is no need for flat plate reinforcement.
Moreover, when the flowing gas is heated or cooled, a heat transfer effect through the flat plate of the flowing gas can be expected.
[0015]
<Invention of Claim 3 >
The fluidized bed apparatus according to claim 1 or 2, wherein one end portion of the main body is openable, and a panel heat exchanger can be carried into the main body from the open portion.
[0016]
(Function and effect)
As shown in FIG. 4 (1), openings 90, 90... Are formed on the side surface of the main body 2, and when the panel heat exchanger 5 is carried from the openings 90, the openings 90 are formed in the panel heat. Since it is necessary to form the same number as the number of exchangers 5, it leads to an increase in equipment cost and design cost. Further, the opening 90 is sealed with, for example, a cover material (not shown) after the panel heat exchanger 5 is carried in. However, since the opening 90 is a curved surface, the structure for sealing the opening 90 is complicated. It will be a thing. Therefore, the equipment cost and the design cost are further increased. Furthermore, depending on the structure of the apparatus, the flat plate 6 may become an obstacle to carrying in the panel heat exchanger 5.
On the other hand, in the apparatus of the present invention, one end of the main body can be opened, and the panel heat exchanger can be carried into the main body from this open part. This is enough to prevent an increase in equipment and design costs. Moreover, since the opening portion side end edge of the main body can be a simple annular flange corresponding to the pressure, it can be handled with a simple structure.・ An increase in design cost is prevented.
[0017]
<Invention of Claim 4 >
A rail member extending along the axial direction is provided in the main body, and supported by loading means that is movable on the rail member so that the panel heat exchanger is loaded into the main body from the open portion. The fluidized bed apparatus according to claim 3 .
[0018]
(Function and effect)
A rail member extending along the axial direction is provided in the main body, supported by a loading means that is movable on the rail member, and a panel heat exchanger is loaded into the main body from the opening. Therefore, the operation of installing the panel heat exchanger in the main body is simplified.
[0019]
<Invention of Claim 5 >
The fluidized bed apparatus according to claim 4 , wherein the fluidized gas blown into the side region from the bottom region is blown out toward the upper surface of the rail member from the side region.
[0020]
(Function and effect)
When the workpiece is fluidized, a part of the workpiece is deposited on the rail material. Therefore, there is a possibility that the whole object to be processed cannot be completely dried. However, in the apparatus of the present invention, the flowing gas blown from the bottom region to the side region is blown out from the side region toward the upper surface of the rail material. There is no accumulation. Therefore, the entire workpiece can be completely dried.

[0022]
(Function and effect)
The flat plate has its upper edge reaching the inner wall of the main body, and a part of the flat plate can be freely opened along the axial direction, and a rail material is provided on the side region side from the opening, and when the workpiece is fluidized Since the opening is closed, the workpiece is not deposited on the rail material.

(Function and effect)
Since the upper end of the main body is opened and a sedimentation chamber having an exhaust port is connected so as to cover the opening, the horizontal cross-sectional area of the upper end of the main body is enlarged. Tower speed is reduced. Therefore, the object to be processed that is discharged together with the exhaust gas from the exhaust port is reduced.
[0025]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
3, 5, and 6 show a fluidized bed apparatus 1 according to the present embodiment.
The fluidized bed apparatus 1 includes a main body 2 to which a workpiece P is supplied, a dispersion plate 3 installed in the main body 2, and a plurality of panel types installed in the main body 2 above the dispersion plate 3. The heat exchanger 5 is mainly included.
[0026]
A flowing gas G blowing port 7 is formed at the bottom of the main body 2, and compressed air or the like is supplied from the flowing gas blowing port 7 to a bottom region 30 surrounded by the peripheral wall of the main body 2 and the dispersion plate 3. Fluid gas G is blown. The flowing gas G blown into the bottom region 30 is further blown up through the dispersion plate 3, and the workpiece P is fluidized by the blowing gas G. The fluidized workpiece P is heated or cooled in contact with the panel heat exchanger 5.
[0027]
As shown in FIG. 3 (1) and FIG. 6, the main body 2 has a horizontal cylindrical shape whose axial direction is the horizontal direction. At the upper end of the main body 2, a supply port 8 for the workpiece P and exhaust ports 9 and 9 for the flowing gas G are formed. The workpiece P supplied from the supply port 8 is moved in the axial direction (rightward in the drawing) while being flowed by the flowing gas G, and the discharge port of the workpiece P provided at one end of the main body 2. 10 is discharged out of the apparatus. The workpiece discharge port 10 is provided with a rotary valve 11, and the discharge of the workpiece P to the outside of the apparatus is controlled.
[0028]
As shown in FIG. 6, heating or cooling of the panel heat exchanger 5 is performed by supplying a heat medium / refrigerant from a heat medium / refrigerant supply pipe 16 such as steam, hot water, or cooling water. The heat medium / refrigerant used for heating or cooling the workpiece P is discharged from the heat medium / refrigerant discharge pipe 17.
[0029]
The panel heat exchanger 5 is preferably in the form of a panel having a square or rectangular heat transfer surface from the viewpoint of improving the heat transfer efficiency, and this heat transfer surface (panel surface) is the main body 2. It is preferable that it is installed so as to be orthogonal to the axial center. However, the specific structure is not particularly limited. For example, as shown in (1) of FIG. 14, a thin box-shaped panel body 5A connected to the heat medium / refrigerant supply pipe 16 and the heat medium / refrigerant discharge pipe 17 is provided, and the inner space thereof is horizontal. What was partitioned off by the some flow-path control board 5a, 5a ... extended in the direction can be used. The flow path control plate 5a is provided so that one end is connected to the inner wall of the panel body 5A and the other end is separated from the inner wall of the panel body 5A. It is connected to the inner wall of 5A.) The channel control plates 5a and 5a adjacent to each other in the vertical direction are provided such that the end portions on the separated side are located on the opposite sides in the longitudinal direction of the channel control plate. Accordingly, the heat medium / refrigerant supplied from the heat medium / refrigerant supply pipe 16 moves downward while meandering from one end to the other end and from the other end to the other end in the panel body 5A. 17 will be discharged. In the panel heat exchanger 5 of this form, the panel body 5A is reinforced by the flow path control plate 5a, so that the panel type heat exchanger 5 can sufficiently withstand even if a large pressure is applied to the panel body 5A.
[0030]
Further, as the panel heat exchanger 15, a panel portion is formed by meandering pipes 5b connected to the heat medium / refrigerant supply pipe 16 and the heat medium / refrigerant discharge pipe 17, as shown in FIG. It is also possible to use what has been made. In the panel type heat exchanger 5 of this embodiment, all members constituting the panel type heat exchanger 5 serve as heat transfer surfaces (by the way, the previous flow path control plate 5a is not a heat transfer surface). This is suitable for reducing the weight of the panel heat exchanger 5.
[0031]
Further, when steam is used as the heat medium, the panel-type heat exchanger 5 having the configuration shown in FIG. 14 (1) may be configured without the flow path control plates 5a, 5a.
[0032]
From the viewpoint of improving heat transfer efficiency, the panel heat exchanger 5 is preferably as large as possible (the panel surface is wide) as long as it can be carried into the main body 2. For example, it is possible to use one in which both side edges of the panel surface are separated from the flat plate 6 by 50 mm.
[0033]
The number of flowing gas blowing ports 7 formed at the bottom of the main body 2 can be one, but is preferably two, three, or more. As the workpiece P moves in the direction of the two axial axes of the main body, its state gradually changes (for example, it becomes dry and lighter). This is because it is necessary to change the pressure. In the present embodiment, the number of flowing gas blowing ports 7 is three.
[0034]
When there are a plurality of flowing gas blowing ports 7, it is preferable to have a plurality of bottom regions 30 in accordance with this. In the present embodiment, the partition plate 31 has three bottom regions.
[0035]
In the present embodiment, the dispersion plate 3 is installed below the position of the main body center (axial center). Although the dispersion plate 3 can be installed horizontally, it can also be installed so that it may become a downward gradient toward the moving direction of the to-be-processed object P. FIG. Flat plates 6 and 6 are provided on both side edges of the dispersion plate 3 so as to extend upward.
[0036]
Although various installation forms of the dispersion plate 3 and the flat plate 6 can be considered, as shown in FIG. 7, the bottom region 30 and the side region 40 surrounded by the peripheral wall of the main body 2 and the flat plate 6 are installed in a communicating state. Is preferred. Thereby, the pressure of the side area | region 40 and the pressure of the flow area | region 50 become substantially equal. The reason why the pressure is substantially in the flow region 50 is that it is lost by the dispersion plate 3 and the workpiece P and is not completely the same as the side region 40. However, this pressure difference is preferably designed to be within 15 KPa, and particularly preferably designed to be within 10 KPa.
[0037]
As a method for establishing the communication state, for example, a method in which the dispersion plate 3 and the flat plate 6 are installed by being supported by other members at a position away from the inner wall of the main body 2, or the flat plate 6 extends upward from the inner wall of the main body 2. A method of connecting the side edges of the dispersion plate 3 to the middle portion of the flat plate 6 and forming an opening below the dispersion plate connecting portion of the flat plate 6 can be considered.
[0038]
By the way, in the fluidized bed apparatus 1 according to the present embodiment, as shown in FIG. 4 (2) and FIG. 8, one end of the main body 2 can be opened in the axial direction, for example. The panel heat exchanger 5 can be carried into the main body 2 from 12.
[0039]
As schematically shown in FIG. 4 (2), the panel type heat exchanger 5 may be carried in one by one, but from the viewpoint of work efficiency, a plurality of panel type heat exchangers 5 are connected to each other. It is preferable to carry in as the heat exchanger group 5G. In the present embodiment, five panel type heat exchangers 5 are connected to form a panel type heat exchanger group 5G.
[0040]
The method for carrying in the panel type heat exchanger 5 or the panel type heat exchanger group 5G (hereinafter abbreviated as “panel type heat exchanger (5)” including these) is not particularly limited. However, as in the present embodiment, a pair of rail members 13, 13 along the axial direction are provided in the main body 2, and the panel-type heat is provided by the loading means 14 that is movable on the rail members 13, 13. It is preferable that the exchanger or the like (5) is supported and carried into the main body 2 from the opening portion 12.
[0041]
In the present embodiment, the carrying-in means 14 mainly includes a flat plate-like main body 14A and two wheels 14B provided on each side surface thereof. As this wheel 14B rolls on the rail member 13, as shown in FIG. 9, the carrying-in means 14 moves into the main body 2 while supporting (suspending) the panel heat exchanger or the like (5). . After the panel type heat exchanger or the like (5) is moved to a predetermined position in the main body 2, the panel type heat exchanger or the like (5) is removed from the carrying-in means 14. Then, as shown in FIG. 6, the panel-type heat exchanger or the like (5) is attached and fixed to the support 15 fixed to the flat plate 6, and further, the heat medium / refrigerant supply pipe 16 and the heat medium / refrigerant discharge pipe 17. Connect with.
[0042]
In the present embodiment, an extension rail member 13A having the same shape as the rail member 13 is connected to the edge of the rail member 13 on the opening portion 12 side. Thereby, carrying-in of panel type heat exchangers etc. (5) is facilitated.
[0043]
Moreover, in this Embodiment, the annular flanges 18 and 18 which protrude in the periphery outward are provided in the open part 12 side edge of the main body 2. As shown in FIG. Thereby, it is possible to completely prevent the workpiece P and the flowing gas G in the main body 2 from leaking to the outside during the product temperature adjustment process.
[0044]
Furthermore, in the present embodiment, one end edge of the dispersion plate 3 and the flat plate 6 only extends to the end edge side position of the main body 2 on the opening portion 12 side. Then, a second flat plate 6 </ b> A is provided at one end edge of the dispersion plate 3 and the flat plate 6 so as to be along the open portion 12 side edge of the main body 2. Thereby, the superficial velocity is made uniform.
[0045]
As described above, when the rail members 13 and 13 are provided in the main body 2 and the panel-type heat exchanger or the like (5) is carried in using the rail members 13 and 13, the operation is facilitated. As described above, when the workpiece P is fluidized, a part of the workpiece P may be deposited on the rail members 13 and 13 and the entire workpiece P may not be completely dried. Therefore, in the present embodiment, as shown in FIG. 10, an opening 6K is formed in the upper end portion of the flat plate 6 along the axial direction, and along the lower edge of the opening 6K, and the flat plate 6 The rail material 13 was provided on the flow region 50 side. Thereby, the flowing gas G blown into the side region 40 from the bottom region 30 is blown out toward the upper surface of the rail member 13 from the side region 40 through the opening 6K, and thus the workpiece to the rail member 13 is processed. P deposition is prevented. From the viewpoint of strengthening the blowing of the flowing gas G, it is preferable to bring the rail material 13 close to the flat plate 6, and it is particularly preferable to weld the rail material 13 to the flat plate 6. When the rail member 13 is welded to the flat plate 6, the support member for the rail member 13 becomes unnecessary, and the structure inside the main body 2 becomes simple.
[0046]
In the present embodiment, the structure is such that the flowing gas G is simply blown out from the opening 6K. However, from the viewpoint of strengthening the blowing, a blowing nozzle or a blowing plate in which a large number of holes are formed at the opening position. It is preferable that the fluid gas G is blown out from these.
[0047]
The shapes of the opening, the blowing nozzle, and the blowing plate can be appropriately designed based on the blowing distance, the blowing area, the blowing pressure, the blowing amount, and the like. The blowing distance and the blowing area are determined by the shape of the rail material, the installation position, and the like. Further, the blowing pressure is a value obtained by subtracting the pressure in the side region 40 (the same pressure as the bottom region 30) and the pressure in the flow region 50 (the pressure loss in the dispersion plate 3 from the pressure in the bottom region 30 and the pressure loss in the flow region 50). ) Affected by the difference. The amount of blowout is determined by the relationship between the blowout distance, the blowout area, and the blowout pressure, but is preferably as small as possible. This is because if the amount of blowout is large, the amount of circulating gas increases, so that it is necessary to enlarge the facility, which is not economical.
[0048]
The prevention of the deposition of the workpiece P on the rail material 13 can be achieved not only by the above structure but also by a structure as shown in FIG.
That is, the upper end edge of the flat plate 6 reaches the inner wall of the main body 2 and a part of the flat plate 6 can be opened along the axial direction. The rail member 13 is provided on the side region 40 side of the opening 6L. When the material P is fluidized, the opening 6L is closed. In the present embodiment, in particular, the upper end portion of the flat plate 6 is constituted by the lid member 20, and can be opened by opening and closing the lid member 20. By closing the opening 6 </ b> L with the lid member 20, deposition of the workpiece P on the rail member 13 is prevented. FIG. 9 shows a state in which the wheel 14B rolls on the rail member 13 in the case of this structure.
[0049]
Incidentally, as described above, in the fluidized bed apparatus 1, the exhaust port 9 is formed at the upper end portion of the main body 2, and the flowing gas G is discharged from the exhaust port 9. However, depending on the dry state of the object to be processed P, a part of the object to be processed P may be contained in the flowing gas G and discharged from the exhaust port 9. Therefore, from the viewpoint of preventing this, it is preferable that the fluidized bed apparatus 1 has the structure shown in FIGS.
In other words, the upper end of the main body 2 is opened, and the sedimentation chamber 22 having the exhaust port 9 is connected so as to cover the opening. Thereby, since the horizontal cross-sectional area of the upper end of the main body 2 is enlarged and the superficial velocity is reduced, the discharge of the workpiece P from the exhaust port 9 is prevented.
[0050]
As the shape of the sedimentation chamber 22, various shapes are conceivable, but it is preferable to use an arc shape. By adopting an arc shape, pressure resistance is improved.
