Description

The present invention relates to a cooling device used in a treatment system that removes odorous components contained in odors discharged from a treatment device (e.g., a fermentation treatment machine), and the treatment system equipped with the cooling device.

Technologies have been proposed for fermenting materials to be treated, such as food waste, in a fermentation tank to turn them into compost (see, for example, Patent Document 1). Microorganisms (e.g., aerobic bacteria) are used to ferment the materials to be treated.

JP 2008-126161 A

In order to promote the decomposition and fermentation of the material by microorganisms, the temperature inside the fermentation tank is kept relatively high (e.g., 40°C or higher).

Meanwhile, odors are generated in the fermentation tank during the fermentation process of the material being treated. The odors are sent to a deodorizing device where most of the odorous components are removed, and then discharged to the outside. The most commonly known deodorizing method used in deodorizing devices is the adsorption method, which uses activated carbon to adsorb and remove odorous components.

However, it is known that when activated carbon is used at temperatures above 40°C, its ability to adsorb odorous components decreases. It is also known that when activated carbon becomes wet, its ability to exert its adsorption capabilities is hindered. Therefore, in order to reliably obtain the deodorizing effect of activated carbon in a deodorizing device, it is necessary to cool the odors supplied to the deodorizing device to lower the odor temperature and remove the water vapor contained in the odor. However, Patent Document 1 does not consider cooling the odors at all.

If the configuration for cooling odors is complicated, the treatment system itself, including the treatment device such as the fermentation treatment machine and the deodorization device, may become large, making it difficult to build the treatment system. For this reason, it is desirable to achieve cooling of odors with a simple configuration.

The present invention has been made to solve the above problems, and its purpose is to provide a cooling device that can cool odors with a simple configuration, and a treatment system equipped with the cooling device.

The cooling device according to one aspect of the present invention comprises a housing having an inlet through which odors discharged from a treatment device flow and an outlet through which the odors flow to a deodorizing device, and a cooling section provided on the outside of the housing for cooling the housing.

Odors can be cooled with a simple configuration.

The embodiment of the present invention will be described below with reference to the drawings.

1. Processing System
Fig. 1 is an explanatory diagram showing a schematic configuration of a treatment system 1 according to the present embodiment. The treatment system 1 includes a treatment device 2, a filter device 3, a cooling device 4, and a deodorization device 5. In Fig. 1, the arrows shown by dashed lines indicate the paths along which gas such as odor flows.

(1-1. Processing Device)
The processing device 2 is, for example, a fermentation processor 2a that ferments the material G to be processed. The material G to be processed may be, for example, food waste generated in a home or a store. In this case, the fermentation processor 2a constitutes a food waste processor. The fermentation processor 2a includes a fermenter 21 and an equipment arrangement section 22.

The equipment arrangement section 22 includes a motor 221 that serves as a power source for rotating the rotating shaft 211 in the fermentation tank 21, a power transmission section 222 (including gears, shafts, etc.) for transmitting the rotational driving force of the motor 221 to the rotating shaft 211, a blower 223 for supplying oxygen-containing gas to the air supply pipe 212, and the like.

The fermentation tank 21 ferments the material G to be treated therein. More specifically, the fermentation tank 21 has a double structure consisting of a treatment tank and a main body cover, and the material G to be treated is placed in the treatment tank and fermented. The treatment tank is heated by a heater (not shown). This maintains the inside of the treatment tank within a predetermined temperature range (e.g., 40°C or higher). As a result, fermentation by microorganisms (e.g., aerobic bacteria) contained in the material G to be treated is carried out well in the treatment tank.

The material G to be treated is loaded into the fermentation tank 21 (treatment tank) by opening the lid 21a provided, for example, at the top of the fermentation tank 21. After the material G to be treated is loaded, the lid 21a is closed and the rotating shaft 211 in the fermentation tank 21 is rotated. This causes multiple stirring claws 211a attached to the outer circumferential surface of the rotating shaft 211 to rotate, stirring the material G to be treated in the fermentation tank 21. The material G to be treated is then composted by fermentation and drying in the fermentation tank 21. The composted material G to be treated is removed from the fermentation tank 21 by reopening the lid 21a.

The position of the lid 21a is not limited to the top of the fermenter 21, but may be, for example, on the side of the fermenter 21. The shape of each stirring claw 211a and the mounting position along the rotation shaft 211 can be set arbitrarily.

Oxygen-containing gas is introduced into the fermentation tank 21 through the air supply pipe 212. This promotes fermentation of the material G to be treated by microorganisms in the fermentation tank 21.

The fermentation tank 21 is provided with an exhaust port 213. The fermentation odor (odor) generated by the fermentation of the material G to be treated in the fermentation tank 21 is discharged toward the filter device 3 through the exhaust port 213. Note that odor refers to a gas containing odorous components. The odor may contain components other than the odorous components (e.g., water vapor, nitrogen, oxygen, carbon dioxide). The odor discharged from the fermentation tank 21 may also contain dust generated by the stirring of the material G to be treated.

(1-2. Filter Device)
The filter device 3 has a filter section 31 and a storage section 32 that stores the filter section 31. A pipe 6a that is connected to an exhaust port 213 of the treatment device 2 (fermentation processor 2a) is connected to a lower part of the storage section 32. The filter section 31 is, for example, cylindrical, and is located inside and above the storage section 32.

When odors flow from the fermentation processor 2a into the storage section 32 through the pipe 6a, the dust contained in the odors cannot pass through the filter section 31 and remains on the outer surface of the filter section 31. On the other hand, odors other than dust pass through the filter section 31 from the outside to the inside in the radial direction. The odors that pass through the filter section 31 are discharged toward the cooling device 4 through the exhaust port 33 located on the upper inside of the filter section 31.

In this embodiment, the filter device 3 is provided outside the fermentation processor 2a, but it may also be provided inside the fermentation processor 2a.

(1-3. Cooling device)
The cooling device 4 cools the odor that flows in from the treatment device 2 (fermentation treatment machine 2a) through the filter device 3, and discharges the cooled odor toward the deodorization device 5b. Therefore, the cooling device 4 has an inlet 4a through which the odor discharged from the treatment device 2 flows in, and an outlet 4b through which the odor flows out to the deodorization device 5. The inlet 4a is connected to the outlet 33 of the filter device 3 through a pipe 6b. The outlet 4b is connected to the deodorization device 5 through a pipe 6c.

In this embodiment, the cooling device 4 is provided outside the fermentation processor 2a, but it may also be provided inside the fermentation processor 2a together with the filter device 3. Details of the cooling device 4 will be described later.

(1-4. Deodorizing device)
The deodorizing device 5 is a deodorizing device that removes odorous components contained in the odor flowing out from the cooling device 4. In this embodiment, the deodorizing device 5 is composed of an activated carbon adsorption tower 5a. The activated carbon adsorption tower 5a has an activated carbon adsorption section 51 that contains activated carbon that adsorbs odors.

The cooling device 4 and the deodorizing device 5 described above are mounted, for example, on a common mounting base (pallet) 7, but they may also be mounted on separate mounting bases.

The operation of the treatment system 1 having the above configuration is as follows. The treatment device 2 (fermentation treatment machine 2a) of the treatment system 1 ferments the material G to compost it. Odors such as fermentation odors (for example, 40°C or higher) generated in the fermentation treatment machine 2a are supplied to the filter device 3 via the pipe 6a. In the filter device 3, dust contained in the odor is removed by the internal filter 31. The odor from which the dust has been removed is sent from the filter device 3 via the pipe 6b to the cooling device 4. After being cooled by the cooling device 4, the odor is sent to the deodorizing device 5 via the pipe 6c. In the deodorizing device 5, most of the odor components contained in the odor are adsorbed and removed by the activated carbon in the activated carbon adsorption section 51. The gas from which the odor components have been removed is discharged to the outside from the deodorizing device 5.

Thus, the treatment system 1 of this embodiment includes a cooling device 4, a treatment device 2 that discharges odors into the cooling device 4, and a deodorization device 5 that uses activated carbon to adsorb and remove odorous components contained in the odor that flows out from the cooling device 4.

By cooling the odor discharged from the treatment device 2 in the cooling device 4, not only does the temperature of the odor drop, but the water vapor contained in the odor is condensed. This allows the water vapor to be separated from the odor as condensed water. Therefore, the cooling device 4 can supply odor at a temperature and humidity suitable for the activated carbon to perform its function (the function of adsorbing and removing odorous components) to the deodorizing device 5. Therefore, the deodorizing device 5 can reliably cause the activated carbon to perform its function of removing odorous components, thereby reliably obtaining a deodorizing effect.

The treatment system 1 of this embodiment further includes a filter device 3 that removes dust contained in the odor. The filter device 3 is located between the treatment device 2 and the cooling device 4. In other words, in the flow direction of the odor from the treatment device 2 to the cooling device 4, the filter device 3 is located upstream of the cooling device 4.

If dust is contained in the odor, the dust may cause corrosion inside the cooling device 4. In addition, when the odor is sent from the cooling device 4 to the deodorizing device 5, the dust contained in the odor may clog the fine pores in the activated carbon, which may reduce the deodorizing function of the activated carbon. By locating the filter device 3 upstream of the cooling device 4, the dust in the odor can be removed by the filter device 3 before the odor enters the cooling device 4. This makes it possible to suppress the occurrence of corrosion inside the cooling device 4 caused by the dust. In addition, it is possible to suppress the reduction in the deodorizing function of the activated carbon in the deodorizing device 5 downstream of the cooling device 4.

The processing device 2 also includes a fermentation processor 2a that ferments the material G. In this case, the odorous components contained in the odor (fermentation odor) generated by the fermentation of the material G in the fermentation processor 2a can be reliably removed by the deodorizing device 5.

[2. Details of the cooling device]
Next, the cooling device 4 will be described in detail. For ease of explanation, the directions are defined as follows. First, the direction of gravity is the Z direction. The upstream side of the direction of gravity is defined as "up" and the downstream side is defined as "down". Therefore, the direction from "up" to "down" is the positive Z direction (+Z direction), and conversely, the direction from "down" to "up" is the negative Z direction (-Z direction). The Z direction is defined as the direction from the inlet 4a to the outlet 4b within the housing 41 shown in FIG.
This corresponds to the direction along the odor flow path toward b.

In addition, in a plane perpendicular to the Z direction, two mutually perpendicular directions are defined as the X direction and the Y direction. The X direction corresponds to the left-right direction, and the Y direction corresponds to the front-rear direction. In this case, the upstream side of the X direction is defined as the "left" and the downstream side is defined as the "right". Therefore, the direction from "left" to "right" is the positive direction of the X direction (+X direction), and conversely, the direction from "right" to "left" is the negative direction of the X direction (-X direction). Furthermore, the upstream side of the Y direction is defined as the "rear" and the downstream side is defined as the "front". Therefore, the direction from "rear" to "front" is the positive direction of the Y direction (+Y direction), and conversely, the direction from "front" to "rear" is the negative direction of the Y direction (-Y direction). Furthermore, the +Y direction side of the object is defined as the front, and the -Y direction side is defined as the back. The +X direction side and the -X direction side of the object are defined as side faces. Note that the above directional definitions are provided solely for the convenience of explanation, and the directions that represent the actual arrangement and positional relationships of each component are not limited to the above directions.

Figure 2 is a perspective view of the main parts of the cooling device 4. Figure 3 is a perspective view showing the cooling device 4 of Figure 2 in an exploded state. The cooling device 4 has a housing 41, a heat insulating material 42, and a cooling section 43. Note that the cooling section 43 is not shown in Figure 3. The cooling device 4 also has a drainage section 44 (see Figure 4) described below, but the drainage section 44 is not shown in Figures 2 and 3.

(2-1. Housing)
The housing 41 is a cylindrical body having a rectangular cross-sectional shape in the XY plane. In this embodiment, the long side 41a of the rectangle is located along the X direction, and the short side 41b of the rectangle is located along the Y direction. Note that the cross-sectional shape of the housing 41 is not limited to the above-mentioned rectangle, and may be a square or other polygonal shape, or may be a shape having a curved line such as a circle or an ellipse.

The housing 41 is made of metal. Metals that can be used to make up the housing 41 include metals with high thermal conductivity such as copper or aluminum, and alloys with high corrosion resistance such as stainless steel (SUS). In this embodiment, the housing 41 is made of SUS, but is not limited to this.

As shown in FIG. 3, the housing 41 has four thin plate-shaped side walls 41-1 to 41-4. The side walls 41-1 and 41-3 each have the long side 41a described above and are positioned opposite each other in the Y direction. The side walls 41-2 and 41-4 each have the short side 41b described above and are positioned opposite each other in the X direction. The side walls 41-1 to 41-4 are connected in this order clockwise when viewed from above.

The housing 41 has the inlet 4a and outlet 4b shown in FIG. 1. That is, the cooling device 1 has a housing 41 having an inlet 4a through which odor discharged from the treatment device 2 flows in, and an outlet 4b through which odor flows out to the deodorizing device 5. The inlet 4a and outlet 4b are provided in the side wall 41-4 of the housing 41. The inlet 4a and outlet 4b may be provided in any of the other side walls 41-1 to 41-3 of the housing 41. In the housing 41, the inlet 4a is located above the outlet 4b.

The side wall 41-1 of the housing 41 has rectangular openings 4c. The openings 4c are provided at intervals in the Z direction, the same number as the cooling units 43. In this embodiment, six openings 4c are provided in the side wall 41-1, but the number is not limited to this. The openings 4c are covered and sealed by a fixing plate 431 (see FIG. 5, for example) of the cooling unit 43, which will be described later, when the fixing plate 431 is fixed to the outer surface 41-1a of the side wall 41-1. Therefore, a part of the fixing plate 431 is exposed inside the housing 41 through the openings 4c. In other words, the side wall 41-1 of the housing 41 has openings 4c that expose a part of the fixing plate 431 inside the housing 41 when the fixing plate 431 is fixed to the side wall 41-1.

(2-2. Insulation materials)
The insulating material 42 covers a part of the housing 41 from the outside (the side opposite to the internal cavity (the odor flow path)). The insulating material 42 may cover the entire housing 41 from the outside. In other words, the cooling device 4 includes the insulating material 42 that covers at least a part of the housing 41. The insulating material 42 is made of, for example, a foamed plastic material. Examples of the foamed plastic material include polystyrene, polyethylene, and urethane, and an appropriate material can be selected and used from these.

By providing the cooling device 4 with the insulating material 42, for example, even in the summer when the temperature around the housing 41 is high, the insulating material 42 can prevent the heat around the housing 41 from being transferred to the housing 41. This makes it possible to prevent the efficiency of cooling the housing 41 by the cooling unit 43 from decreasing due to the environmental temperature.

The insulation material 42 is composed of individual pieces 42-1 to 42-5. The thicknesses of the individual pieces 42-1 to 42-5 are all the same, but may be different. Furthermore, the individual piece 42-1 is composed of, for example, a single sheet of insulation material, but may also be composed of multiple sheets of insulation material laid out in a tile-like pattern. Similarly, the individual pieces 42-2 to 42-5 may be composed of a single sheet of insulation material, or may also be composed of multiple sheets of insulation material.

The pieces 42-1 to 42-4 are attached to the outer surfaces of the side walls 41-1 to 41-4 of the housing 41, respectively, and cover at least a part of the side walls 41-1 to 41-4 from the outside. The pieces 42-1 and 42-3 are configured to be the same size and are formed to be longer in the X direction than the long side 41a of the housing 41. The pieces 42-2 and 42-4 are configured to be the same size and are formed to be the same length in the Y direction as the short side 41b of the housing 41. The length in the Z direction of the pieces 42-1 to 42-4 is shorter than the length in the Z direction of the housing 41, but may be the same. The piece 42-5 is attached to the pieces 42-1 to 42-4 attached to the housing 41 so as to cover them from above. As a result, the opening at the top of the housing 41 is blocked by the piece 42-5.

In the piece 42-1, an opening 42a that is rectangular when viewed from the +Y direction is formed at a position corresponding (overlapping) to the opening 4c of the housing 41. In this embodiment, six openings 42a are formed at intervals in the Z direction, corresponding to the number of cooling sections 43 and the number of openings 4c. The shape and size of the openings 42a are not particularly limited, and they need only be formed in a shape and size that allows the cooling unit 432 (see FIG. 5) of the cooling section 43, which will be described later, to fit into them.

In the piece 42-4, circular openings 42b and 42c are formed at positions corresponding (overlapping) to the inlet 4a and outlet 4b formed in the side wall 41-4 of the housing 41, respectively. That is, in the piece 42-4, the openings 42b and 42c are formed with a gap in the Z direction, and the opening 42b is located above the opening 42c. The pipe 6b shown in FIG. 1 enters the opening 42b of the piece 42-4 and is connected to the inlet 4a of the housing 41. On the other hand, the pipe 6c shown in FIG. 1 enters the opening 42c of the piece 42-4 and is connected to the outlet 4b of the housing 41.

(2-3. Cooling section)
The cooling unit 43 cools the housing 41 made of metal. The cooling unit 43 is located on the +Y direction side with respect to the housing 41. That is, the cooling device 4 includes the cooling unit 43 that is provided on the outside of the housing 41 and cools the housing 41.

The cooling unit 43 cools the housing 41, thereby lowering the temperature of the housing 41. This allows the odor in the housing 41, that is, the odor flowing from the processing device 2 (see FIG. 1) into the housing 41, to be cooled. In addition, in a configuration in which a heat exchanger or the like is disposed in the housing to cool the odor in the housing, in addition to the heat exchanger, piping and a pump for circulating the refrigerant are also required. As a result, not only does the housing become larger, but the configuration of the cooling device also becomes complicated. In a configuration in which the cooling unit 43 is provided on the outside of the housing 41 as in this embodiment, the cooling unit 43 can be attached to the housing 41 from the outside to easily realize the cooling device 4 that cools the odor in the housing 41. In addition, since piping and a pump that are required when a heat exchanger is used are not required, the cooling device 4 can be avoided from becoming larger and more complicated in configuration. In other words, the odor in the housing 41 can be cooled with a simple configuration of the cooling device 4.

In particular, in this embodiment, as shown in FIG. 2, six cooling units 43 are provided on the side wall 41-1 of the housing 41 along the Z direction. That is, multiple cooling units 43 are provided on the side wall 41-1 of the housing 41 along the odor flow path from the inlet 4a to the outlet 4b. The multiple cooling units 43 increase the area of the housing 41 that is cooled at one time, thereby improving the cooling effect of the housing 41 and the cooling effect of the odor inside the housing 41. It is also possible to fine-tune the cooling temperature of the odor inside the housing 41 by controlling only one of the multiple cooling units 43.

The cooling control of the cooling section 43 will be described in detail later. Of course, the number of cooling sections 43 may be one, but in terms of increasing the odor cooling effect, it is desirable to have multiple cooling sections 43. In this embodiment, the multiple cooling sections 43 are all provided on the same side wall 41-1, but they may also be provided on different side walls.

Figure 4 is a front view showing the appearance of the cooling device 4 from the Y direction. As shown in the figure, the cooling device 4 has a drainage section 44. When the housing 41 is cooled by the cooling section 43 as described above, the water vapor contained in the odor inside the housing 41 condenses into condensed water, which accumulates at the bottom 41L of the housing 41. The drainage section 44 drains the condensed water accumulated at the bottom 41L into the drainage tank 44a. In other words, the cooling device 4 has a drainage section 44 that discharges condensed water that is generated inside the housing 41 by cooling the housing 41 and accumulates at the bottom 41L of the housing 41.

The drain tank 44a is manually transported to a location suitable for discharging the condensed water (for example, a drainage location with proper sewage treatment), and the condensed water in the drain tank 44a is discarded there. If the cooling device 4 itself is installed in a location with proper drainage facilities, the drain unit 44 may drain the condensed water accumulated in the bottom 41L of the housing 41 directly to the drainage location.

The drainage section 44 has a water sealing structure 44b. The water sealing structure 44b is composed of a pipe 44b1 that is connected to the bottom 41L of the housing 41, bends upward (in the -Z direction), remains horizontal at a position at a certain height h1 from the reference h0, and then bends downward (in the +Z direction).

Condensed water generated in the housing 41 and collected at the bottom 41L flows out from the bottom 41L into the pipe 44b1 of the water seal structure 44b. Here, until the height of the condensed water in the housing 41 reaches a predetermined height h1 from the reference h0, the condensed water is kept at the same height in the pipe 44b1 of the water seal structure 44b, so the condensed water is not drained into the drain tank 44a (the condensed water accumulates in the pipe 44b1). On the other hand, when the condensed water accumulated in the bottom 41L of the housing 41 exceeds the predetermined height h1 from the reference h0, the condensed water also exceeds the predetermined height h1 in the pipe 44b1 of the water seal structure 44b, so the excess amount is drained through the pipe 44b1 into the drain tank 44a.

In this way, the drainage section 44 has a water seal structure 44b that stores the condensed water until the condensed water reaches a predetermined height h1 in the housing 41 and discharges the condensed water when the condensed water exceeds the predetermined height h1. As a result, the condensed water generated in the housing 41 is automatically discharged outside the housing 41 when the condensed water exceeds the predetermined height h1. Therefore, it is possible to eliminate the need for management of the discharge of the condensed water. In addition, compared to a configuration in which the condensed water is discharged by opening and closing a valve, it is also possible to eliminate the troublesome opening and closing of a valve. Furthermore, since the drainage section 44 has the water seal structure 44b, only the condensed water can be discharged from the drainage section 44, and only the odor separated from the condensed water can be discharged from the outlet 4b. In other words, the condensed water and the odor can be reliably separated and discharged separately.

Next, the cooling section 43 will be described in detail. FIG. 5 is a front view of the cooling device 4 from the +Y direction side with the piece 42-1 of the insulating material 42 removed. As shown in these figures, the cooling section 43 has a fixing plate 431 and a cooling unit 432.

<2-3-1. Fixing plate
The fixed plate 431 is made of metal, for example, SUS. The fixed plate 431 may be a metal plate having high thermal conductivity, such as aluminum or copper. The outer shape of the plate 431 is larger than the outer shape of the cooling unit 432 and is, for example, rectangular, but may be another shape (for example, square). That is, the cooling unit 43 has a fixing plate 431 that is fixed to the outer surface 41-1a of the side wall 41-1 of the housing 41.

Specifically, the solid plate 431 is fixed to the side wall 41-1 of the housing 41 as follows. FIG. 6 is an enlarged front view of the cooling section 43. Through holes 431a are formed in the four corners of the rectangular fixed plate 431. In addition, a through hole 431a is also formed between two adjacent corners of the fixed plate 431. In other words, a total of eight through holes 431a are formed on the periphery of the fixed plate 431. Note that the number of through holes 431a is not limited to eight, and may be set to any number.

On the other hand, as shown in FIG. 3, a mounting hole 4d of approximately the same size as the through hole 431a is formed in the side wall 41-1 of the housing 41 at a position corresponding to the through hole 431a of the fixing plate 431. The fixing plate 431 can be fixed to the outer surface 41-1a of the side wall 41-1 by inserting a screw V1 (see FIG. 5) into the through hole 431a of the fixing plate 431 and the mounting hole 4d of the housing 41 from the +Y direction side, and screwing and tightening a nut (not shown) on the inside of the housing 41 (the opposite side to the fixing plate 431). Note that the cooling unit 432 is fixed to the fixing plate 431 by a method described later, so that the cooling section 43 including the fixing plate 431 and the cooling unit 432 can be fixed to the side wall 41-1 by fixing the fixing plate 431 to the side wall 41-1 of the housing 41.

The pieces 42-1 constituting the above-mentioned heat insulating material 42 are attached to the side wall 41-1 of the housing 41 after the cooling section 43 is fixed to the housing 41. At this time, as shown in FIG. 2, the cooling unit 432 protrudes in the +Y direction through the opening 42a of the piece 42-1, but the peripheral portion of the fixing plate 431 is covered by the piece 42-1 and is not exposed to the outside (+Y direction) of the housing 41.

<2-3-2. Cooling unit>
The cooling unit 432 comes into contact with the fixed plate 431 to cool the fixed plate 431. That is, the cooling section 43 has the cooling unit 432 that cools the fixed plate 431. The cooling unit 432 cools the fixed plate 431, thereby cooling the housing 41 in which the fixed plate 431 is fixed to the side wall 41-1. This ensures that the odor inside the housing 41 is cooled.

7 is a side view of the cooling unit 432 as viewed from the +X direction. FIGS. 8 and 9 are a side view of the cooling unit 432 as viewed from the +X direction and a rear view of the cooling unit 432 as viewed from the -Y direction, respectively, without illustrating a heat insulating member 432-1e, which will be described later.
The cooling unit 2 has a main body portion 432-1, heat dissipation fins 432-2, and an air-cooling portion 432-3.

The heat dissipation fins 432-2 are composed of multiple thin metal plates arranged in parallel. The heat dissipation fins 432-2 are located on the +Y direction side of the main body 432-1, that is, on the heat dissipation side of the Peltier element 432-1b (described later) of the main body 432-1. As a result, the heat generated by the Peltier element 432-1b is transferred to the heat dissipation fins 432-2, where it is released to the outside.

The mounting plate 432-1c, which will be described later, is attached to the heat absorption side (cooling side) of the Peltier element 432-1b. For this reason, it can be said that the heat dissipation fins 432-2 are located on the opposite side of the body part 432-1 to the mounting plate 432-1c. In other words, the cooling unit 432 has heat dissipation fins 432-2 that are connected to the opposite side of the body part 432-1 to the mounting plate 432-1c.

The air cooling section 432-3 is located on the +Y direction side of the heat dissipation fins 432-2 and cools the heat dissipation fins 432-2. In other words, the cooling unit 432 has an air cooling section 432-3 that cools the heat dissipation fins 432-2. The air cooling section 432-3 has a cooling fan 432-3a, a housing 432-3b, and a motor (not shown).

The cooling fan 432-3a is rotated by a motor and blows air toward the heat dissipation fins 432-2. This allows the heat dissipation fins 432-2 to be cooled. The motor is connected to the control device 48 (see FIG. 22) via two conductors 432-3c.

The housing 432-3b houses the cooling fan 432-3a and the motor. In the housing 432-3b, a mesh portion 432-3b1 is provided on the +Y direction side of the cooling fan 432-3a. This mesh portion 432-3b1 ensures ventilation when the cooling fan 432-3a rotates, and prevents the cooling fan 432-3a from coming into contact with the outside. The housing 432-3b is fastened to the heat dissipation fins 432-2 by inserting screws V2 into the four corners when viewed from the +Y direction side.

The main body 432-1 has a main body housing 432-1a that houses a Peltier element 432-1b. In other words, the cooling unit 432 has a Peltier element 432-1b. The main body housing 432-1a is fastened to the heat dissipation fins 432-2 by inserting screws V3 into the four corners when viewed from the -Y direction side.

The Peltier element 432-1b is a semiconductor element that cools an object by utilizing the Peltier effect, in which heat is transferred from one metal to the other when a current is passed through the junction between two types of metal. Specifically, the Peltier element 432-1b is configured by alternately connecting an N-type semiconductor, a metal, and a P-type semiconductor between a pair of metal plates. When a current is passed through the Peltier element 432-1b, a heat absorption phenomenon occurs at the junction between the N-type semiconductor and the P-type semiconductor, and a heat dissipation phenomenon occurs at the junction between the P-type semiconductor and the N-type semiconductor. For this reason, by bringing the metal that joins the N-type semiconductor and the P-type semiconductor into contact with one metal plate and bringing the metal that joins the P-type semiconductor and the N-type semiconductor into contact with the other metal plate, a heat absorption phenomenon occurs in one metal plate and a heat dissipation phenomenon occurs in the other metal plate. Therefore, by passing a current through the Peltier element 432-1b, the one metal plate can be cooled. Such a Peltier element 432-1b is connected to the control device 48 (see FIG. 22) via two conductors 432-1d.

In this embodiment, the one metal plate which becomes the cooling side of the Peltier element 432-1b is connected to a mounting plate 432-1c made of metal (for example, aluminum). The mounting plate 432-1c is attached to the fixed plate 431 by a method described later. That is, the cooling unit 432 of this embodiment includes a main body 432-1 which houses the Peltier element 432-1b and has a mounting plate 432-1c which is connected to the Peltier element 432-1b and attached to the fixed plate 431.

The main housing 432-1a is covered with a heat insulating member 432-1e. This makes it possible to suppress the transfer of heat between the main housing 432-1a and the outside, and to suppress loss of the cooling effect of the Peltier element 432-1b. The heat insulating member 432-1e is made of the same heat insulating material as the heat insulating material 42 (see Figures 2 and 3) described above. The external shape of the heat insulating member 432-1e when viewed from the +Y direction side is approximately the same as the external shape of the heat dissipation fins 432-2.

The heat insulating member 432-1e is provided in the ZX plane, surrounding the main housing 432-1a. This exposes the outer surface of the mounting plate 432-1c of the main housing 432-1a, i.e., the surface 432-1cS opposite the contact side with the Peltier element 432-1b in the Y direction, allowing the cooling unit 432 to be fixed to the fixing plate 431 described above. More details are as follows.

Figure 10 is an exploded perspective view of the cooling section 43. Figure 11 is a perspective view of the cooling section 43 after the cooling unit 432 has been attached to the fixed plate 431. For convenience, the partition plate 45 (see Figure 12) and slit 431c (see Figure 15) provided on the fixed plate 431 are omitted from Figures 10 and 11.

As shown in FIG. 9 and FIG. 10, mounting holes 432-1cH are provided at the four corners of the surface 432-1cS of the mounting plate 432-1c. The mounting holes 432-1cH have a female screw structure. Meanwhile, near the center of the fixed plate 431, four through holes 431b are provided at positions corresponding to the mounting holes 432-1cH of the mounting plate 432-1c. As shown in FIG. 11, the mounting plate 432-1c and the fixed plate 431 can be fixed by inserting screws V4 into the through holes 431b of the fixed plate 431 and the mounting holes 432-1cH of the mounting plate 432-1c from the -Y direction side and screwing them into the mounting holes 432-1cH. Therefore, the cooling unit 432 having the mounting plate 432-1c can be fixed to the fixed plate 431. Then, the cooling unit 43 in which the cooling unit 432 and the fixed plate 431 are integrated can be realized.

As described above, the cooling unit 432 is configured with the Peltier element 432-1b. Since the Peltier element 432-1b is small, the cooling section 43 can be configured to be small (compared to the case where a heat exchanger such as a chiller is used). Also, as described above, since the cooling section 43 is provided outside the housing 41, it can be said that the Peltier element 432-1b of the cooling unit 432 is also provided outside the housing 41. Due to such a positional relationship between the housing 41 and the Peltier element 432-1b, the Peltier element 432-1b can be protected from corrosive substances (e.g., water vapor) contained in the odor inside the housing 41. This makes it easy to use the Peltier element 432-1b as a means for cooling the odor, and a configuration in which the odor is cooled by the Peltier element 432-1b can be easily realized.

The cooling unit 432 also has the above-mentioned main body 432-1, heat dissipation fins 432-2, and air-cooling section 432-3. The mounting plate 432-1c is cooled by the Peltier element 432-1b of the main body 432-1, so that the fixed plate 431 to which the mounting plate 432-1c is attached can be cooled. This allows the housing 41 to which the fixed plate 431 is fixed to be cooled, and the odor inside the housing 41 to be cooled. Also, by attaching the mounting plate 432-1c to the fixed plate 431, the cooling unit 432 including the mounting plate 432-1c can be fixed to the fixed plate 431. Furthermore, since the heat dissipation fins 432-2 are connected to the side of the main body 432-1 opposite to the mounting plate 432-1c, the Peltier element 432-1b
The heat generated on the heat dissipation side of the heat dissipation fins 432-2 can be dissipated to the outside by the heat dissipation fins 432-2. At this time, the heat dissipation fins 432-2 are cooled by the air cooling section 432-3, so that the heat dissipation by the heat dissipation fins 432-2 can be promoted.

(2-4. Partition plate)
12 is a cross-sectional view of the cooling device 4 in any YZ plane. The cooling device 4 of this embodiment further includes a partition plate 45. The partition plate 45 is made of a thin metal plate such as SUS, and is located parallel to the Z direction in the housing 41. As a result, a part of the odor flow path from the inlet 4a to the outlet 4b (see FIG. 3) in the housing 41 is divided in the X direction by the partition plate 45. That is, the cooling device 4 further includes a partition plate 45 located along the odor flow path from the inlet 4a to the outlet 4b in the housing 41. The partition plate 45 may be made of a metal other than SUS (e.g., aluminum, copper, etc.).

The partition plate 45 is connected to the fixed plate 431 of the cooling unit 43 attached to the side wall 41-1 of the housing 41. The side wall 41-1 has an opening 4c that exposes a part of the fixed plate 431 inside the housing 41, as described above. Therefore, the partition plate 45 located inside the housing 41 is fixed to the fixed plate 431 exposed through the opening 4c of the side wall 41-1. In other words, the partition plate 45 is connected to the fixed plate 431 through the opening 4c. Note that since the fixed plate 431 is a flat plate-like member (see FIG. 10), it does not protrude into the housing 41 through the opening 4c.

In this configuration, the cooling unit 432 of the cooling section 43 can cool the housing 41 through the fixed plate 431 and at the same time cool the partition plate 45 connected to the fixed plate 431 through the opening 4c. By cooling the partition plate 45, the odor flowing in contact with the partition plate 45 in the housing 41 and the odor flowing near the partition plate 45 can be cooled. Therefore, the cooling efficiency of the odor in the housing 41 can be increased by both cooling the housing 41 itself and cooling the partition plate 45. In particular, by positioning the partition plate 45 in the housing 41, the contact area of the area where the odor comes into contact in the housing 41 is reliably increased (compared to a configuration without the partition plate 45), so that the effect of improving the cooling efficiency of the odor in the housing 41 can be easily obtained. In addition, the partition plate 45 may be connected to the inner surface of the housing 41, but by connecting it to the fixed plate 431, the cooling section 43 and the partition plate 45 can be configured as one unit (see FIG. 13), making it easier to handle the partition plate 45.

Figure 13 is a plan view showing a state in which the partition plate 45 is fixed to the fixed plate 431. A plurality of the above partition plates 45 are fixed to the fixed plate 431. The plurality of partition plates 45 are parallel to each other and fixed to the fixed plate 431 at a predetermined interval in the X direction. As a result, when the fixed plate 431 is fixed to the side wall 41-1 of the housing 41, the plurality of partition plates 45 are positioned parallel to each other in the housing 41. That is, the partition plates 45 are connected to multiple points of the fixed plate 431 and positioned parallel to each other in the housing 41. In this configuration, odors passing between two adjacent partition plates 45 in the housing 41 can be efficiently cooled by the two adjacent partition plates 45. This can reliably increase the efficiency of cooling odors in the housing 41.

The number of partition plates 45 fixed to the fixed plate 431 may be one. Even in this case, the effect of improving the cooling efficiency of odors inside the housing 41 can be obtained by providing the partition plate 45.

The length in the Z direction of each partition plate 45 is shorter than the width in the Z direction of the opening 4c described above. In addition, the maximum distance in the X direction of the partition plates 45 located at both ends in the X direction is shorter than the width in the X direction of the opening 4c. As a result, when the fixing plate 431 is fixed to the side wall 41-1 of the housing 41, the cooling unit 43 can be moved from the +Y direction side to the -Y direction side so as to insert the multiple partition plates 45 into the opening 4c, and the fixing plate 431 can be fixed to the side wall 41-1. Therefore, even in a configuration in which the multiple partition plates 45 are fixed to the fixing plate 431 (not to the inner surface of the housing 41), the cooling unit 43 can be moved as described above to position the multiple partition plates 45 inside the housing 41.

14 is a side view of the partition plate 45 from the +X direction side. The partition plate 45 has a base portion 451 and a protruding portion 452. The base portion 451 is configured as a thin plate. The protruding portion 452 is configured to have the same thickness as the base portion 451. The protruding portion 452 protrudes from the base portion 451 in a direction perpendicular to the thickness direction of the base portion 451 (e.g., the X direction) (e.g., the Y direction). In other words, the partition plate 45 has a plate-shaped base portion 451 and a protruding portion 452 protruding from the base portion 451 in a direction perpendicular to the thickness direction. The length of the protruding portion 452 in the protruding direction (Y direction) is approximately equal to the thickness of the fixed plate 431 in the Y direction. In this embodiment, the number of protruding portions 452 for one base portion 451 is one, but one base portion 451 may be provided with multiple protruding portions 452.

Figure 15 is a rear view of the fixed plate 431 from the -Y direction side. The fixed plate 431 has slits 431c that receive the protrusions 452 of the partition plates 45. The number of slits 431c is equal to the number of partition plates 45 fixed to one fixed plate 431. In this embodiment, for example, seven slits 431c are provided in the fixed plate 431, but the number of slits 431c is not limited to the above seven.

In the fixed plate 431, the slits 431c are formed at a predetermined interval in the X direction and are positioned parallel to each other. The width of each slit 431c in the X direction is equal to or slightly larger than the thickness of the partition plate 45 in the X direction. On the other hand, the width of each slit 431c in the Z direction is equal to or slightly larger than the length of the protrusion 452 of the partition plate 45 in the Z direction.

16 and 17 are cross-sectional views showing the state before and after the partition plate 45 is inserted into the slit 431c of the fixed plate 431. As shown in FIG. 17, by inserting the protrusion 452 of the partition plate 45 into the slit 431c of the fixed plate 431, the partition plate 45 can be connected to the fixed plate 431 and stably supported even if the partition plate 45 itself is thin. In order to connect the partition plate 45 and the fixed plate 431 more firmly, the contact portion between the partition plate 45 and the fixed plate 431 (for example, the contact portion between the protrusion 452 of the partition plate 45 and the slit 431c) may be joined by welding.

Figure 18 is a cross-sectional view of the housing 41 cut at an arbitrary cross section (XY plane) perpendicular to the Z direction. As shown in the figure, the outer shape of the housing 41 in the XY cross section is rectangular. In other words, when the flow direction of the odor from the inlet 4a to the outlet 4b (both see Figure 3) in the housing 41 is the up-down direction (Z direction), the outer shape of the housing 41 in the cross section perpendicular to the up-down direction is rectangular. The fixing plate 431 is fixed to the side wall 41-1 of the housing 41, which includes the long side 41a of the rectangle. Furthermore, the partition plate 45 is positioned parallel to the short side 41b of the rectangle in the housing 41.

In this configuration, for example, the fixed plate 431 is fixed to the side wall 41-2 or 41-4 (see FIG. 3) including the short side 41b of the rectangle in the housing 41, and the partition plate 45 is positioned parallel to the long side 41a of the rectangle inside the housing 41, so that the protruding length of the partition plate 45 relative to the fixed plate 431 can be made shorter. This allows the partition plate 45 to be stably supported by the fixed plate 431.

(2-5. Deflection Plate)
19 and 20 are plan views each showing a schematic diagram of the deflection plate 46 of the cooling device 4. Also, FIG. 21 is a cross-sectional view of the cooling device 4 having the deflection plate 46 of FIG. 19 and FIG. 20 in any YZ plane. As shown in these figures, the cooling device 4 may further include the deflection plate 46. Note that in FIG. 19 and FIG. 20, the deflection plate 46 is shown hatched in order to easily distinguish the deflection plate 46 from other members.

The deflection plate 46 is made of a thin metal plate such as SUS, and is provided in a part of the odor flow path inside the housing 41. The deflection plate 46 may be made of a metal other than SUS (e.g., aluminum, copper, etc.). The deflection plate 46 is provided perpendicular to the Z direction inside the housing 41, but may also be provided at an angle to the Z direction.

The deflection plate 46 is connected to the lower end (+Z direction side) of the partition plate 45 described above. As a result, when the fixing plate 431 to which the partition plate 45 is connected is fixed to the housing 41, the deflection plate 46 is arranged so as to intersect with the Z direction within the housing 41. In other words, when the flow direction of the odor from the inlet 4a to the outlet 4b (both see FIG. 3) within the housing 41 is the up-down direction (Z direction), the cooling device 4 shown in FIG. 21 further includes a deflection plate 46 that is provided within the housing 41 in a part of the odor flow path intersecting with the up-down direction. The deflection plate 46 is connected to the partition plate 45.

The deflection plate 46 and the partition plate 45 can be connected in the same manner as the partition plate 45 and the fixed plate 431. That is, a protrusion that protrudes in the Z direction is provided on the partition plate, and a slit that receives the protrusion is provided on the deflection plate 46. By inserting the protrusion into the slit, the deflection plate 46 and the partition plate 45 can be connected vertically. The width of the deflection plate 46 in the Y direction is shorter than the length of the partition plate 45 in the Y direction, for example about half, but is not limited to this width.

The mounting position of the deflection plate 46 relative to the partition plate 45 is not particularly limited, but here, as shown in Figures 19 and 20, the mounting position of the deflection plate 46 is made different in the Y direction. That is, as shown in Figure 19, a deflection plate 46 is prepared that is connected to the partition plate 45 on the +Z direction side of the partition plate 45 and shifted in position toward the +Y direction side from the center in the Y direction, and a deflection plate 46 is prepared that is connected to the partition plate 45 on the +Z direction side of the partition plate 45 and shifted in position toward the -Y direction side from the center in the Y direction, as shown in Figure 20. When distinguishing between the deflection plate 46 in Figure 19 and the deflection plate 46 in Figure 20, the deflection plate 46 in Figure 19 is also referred to as deflection plate 46a, and the deflection plate 46 in Figure 20 is also referred to as deflection plate 46b.

The deflection plate 46a is arranged in the housing 41 by connecting the partition plate 45 to the fixed plate 431 and fixing the fixed plate 431 to the housing 41. The deflection plate 46b is arranged in the housing 41 by connecting the partition plate 45 to the fixed plate 431 and fixing the fixed plate 431 to the housing 41. By using two types of deflection plates 46a and 46b that are attached at different positions relative to the partition plate 45, as shown in FIG. 21, it is possible to arrange a plurality of deflection plates 46a and 46b in the Z direction in the housing 41, and to arrange two deflection plates 46a and 46b adjacent to each other in the Z direction with a shift in the Y direction. In other words, in this case, a plurality of deflection plates 46 are provided in the vertical direction in the housing 41, and two deflection plates 46a and 46b adjacent to each other in the vertical direction are positioned with a shift in the vertical direction.

When the cooling device 4 has a deflection plate 46, part of the odor that flows into the housing 41 from the inlet 4a hits the deflection plate 46 and changes its direction of travel. In other words, the odor traveling inside the housing 41 is deflected by hitting the deflection plate 46. This creates a turbulent flow of the odor inside the housing 41, and increases the number of times the odor comes into contact with the inner surface of the housing 41, the fixed plate 431, the partition plate 45, etc. This further improves the cooling efficiency of the odor inside the housing 41. In addition, because the deflection plate 46 is connected to the partition plate 45, it is easy to realize a configuration in which the deflection plate 46 is positioned in part of the odor flow path inside the housing 41.

In particular, as shown in FIG. 21, two deflection plates 46a and 46b adjacent to each other in the Z direction are
In the configuration in which the deflectors 46 are offset from each other in the Z direction, the odor flowing in the Z direction inside the housing 41 can easily increase the chance of colliding with the multiple deflectors 46 during its travel. This ensures that a turbulent flow of the odor can be generated inside the housing 41, and the above-mentioned effect of improving the cooling efficiency of the odor inside the housing 41 can be reliably obtained.

(2-6. Cooling Control)
22 is a block diagram showing a configuration related to the control of the cooling device 4. The cooling device 4 includes a temperature sensor 47 and a control device 48.

The temperature sensor 47 is provided, for example, in the pipe 6c (see FIG. 1) connected to the outlet 4b of the housing 41, and detects the temperature of the odor flowing out from the outlet 4b of the housing 41. That is, the cooling device 4 is equipped with a temperature sensor 47 that detects the temperature of the odor flowing out from the housing 41. Such a temperature sensor 47 is composed of, for example, a thermistor, but may be composed of other temperature sensors (such as a thermocouple).

The control device 48 is configured to have a main control unit 48a and a storage unit 48b. The storage unit 48b is a memory that stores various information such as the operation program of the main control unit 48a. Such a storage unit 48b is configured to include a RAM (Random Access Memory), a ROM (Read Only Memory), etc.

The main control unit 48a is composed of, for example, a CPU (Central Processing Unit) and controls the operation of each part of the cooling device 4. In particular, the main control unit 48a controls the operation of at least one of the multiple (for example, six) cooling units 43 based on the temperature of the odor detected by the temperature sensor 47. For example, the main control unit 48a includes a drive circuit that controls the current flowing to the Peltier element 432-1b included in any one of the cooling units 43. The main control unit 48a then performs PID control of the current flowing to any one of the Peltier elements 432-1b so that the temperature of the odor detected by the temperature sensor 47 approaches a target temperature (for example, 37°C). The control device 48 is connected to a power source (not shown) and is composed of other circuits and elements such as a voltage conversion circuit that converts the voltage supplied from the power source into a predetermined voltage suitable for driving the cooling unit 43.

In this way, the cooling device 4 is equipped with a control device 48 that controls at least one of the multiple cooling sections 43 based on the temperature detected by the temperature sensor 47 so that the temperature approaches the target temperature. This allows the temperature of the odor emitted from the housing 41 to be controlled with high precision to a temperature suitable for deodorization in the deodorizing device 5 (see FIG. 1). In particular, by having the control device 48 control only one of the multiple cooling sections 43, it is not necessary to use a high-performance, expensive control device 48. As a result, the cooling device 4 can be realized at low cost.

If more precise control of the temperature of the odor discharged from the housing 41 is desired rather than cost, it is desirable for the control device 48 to control the operation of two or more cooling units 43 based on the odor temperature detected by the temperature sensor 47.

[3. Other]
In this embodiment, an example has been described in which a fermentation processor 2a that ferments the material G to be treated is used as the treatment device 2, but the treatment device 2 is not limited to the fermentation processor 2a.
