  Hereinafter, an embodiment for implementing a garbage relay facility according to the present disclosure will be described with reference to the accompanying drawings. However, the present disclosure is not limited to only these embodiments.

<First embodiment>
(Garbage collection system)
Hereinafter, the garbage relay facility of the first embodiment will be described with reference to FIGS. As shown in FIG. 1, the refuse collection system has one secondary treatment facility (for example, a recycling center installed in each local government) 2 and a plurality of refuse transfer facilities 1A. That is, the garbage relay facility 1A is provided at a plurality of locations with respect to one secondary treatment facility 2. The garbage collected by a plurality of garbage collection vehicles M is carried into each garbage collection facility 1A in a predetermined area A set in each garbage collection facility 1A.

  Each garbage truck M that carries garbage into the garbage transfer facility 1A collects garbage along a predetermined collection route in the area A. In each area A, there are general households, restaurants, grocery stores, markets, and the like that discharge a large amount of garbage containing a large amount of organic matter such as garbage such as vegetables, meat, and fish. In each area A, there are offices, factories, public facilities, and the like that discharge a large amount of garbage that contains paper, resin, metal, and the like and that contains little organic matter.

  When the garbage truck M collects garbage on a collection route where many households, restaurants, grocery stores, and markets exist, for example, the garbage mounted on the garbage truck M has a low organic matter content. More. In addition, when the garbage truck M collects garbage on a collection route where many establishments, factories, public facilities, and the like exist, the garbage mounted on the garbage truck M has a low organic matter content.

The collection route of each garbage truck M is determined in advance for each time zone, each day of the week, and the like. Thus, for example, for each garbage truck M, the ratio of the organic matter in the actually collected garbage amount is investigated in advance for each collection route. By conducting the preparatory survey carefully, for each collection route of each garbage truck M, whether the ratio of organic matter contained in the garbage finally collected and transported to the garbage transfer facility 1A is equal to or higher than a predetermined ratio It is possible to determine or estimate whether it is less than the predetermined ratio.
The case where it is possible to “confirm” that the ratio of the organic matter in the garbage (waste) collected by the garbage truck M is included in a predetermined ratio or more means that, for example, the worker of the garbage truck M collects all the garbage collected This is a case where it is true that the organic matter is contained in a predetermined ratio or more, such as when only the garbage is found after the actual recognition. On the other hand, the case where it is possible to “estimate” that the organic matter of the garbage (waste) collected by the garbage truck M is included in a predetermined ratio or more, according to data such as the collection route and the weight measurement of the garbage truck M, In this case, it is highly likely that the amount of the organic substance is included in the predetermined amount or more. The “predetermined ratio” is a ratio at which the hydrothermal treatment apparatus can efficiently perform the hydrothermal treatment, and can be appropriately set depending on the type of the hydrothermal treatment apparatus and the conditions of the hydrothermal treatment. For example, if the processing efficiency is good when 60% (60%) or more of organic matter is included in the volume or weight of the entire waste put into the hydrothermal treatment apparatus, the predetermined ratio may be set to 60%.

  In each garbage transfer facility 1A, the garbage collection vehicle M is divided into a first garbage collection vehicle M1 and a second garbage collection vehicle M based on a predetermined ratio of organic matter contained in the garbage determined or estimated for each collection route of each garbage collection vehicle M. Garbage truck M2. The first refuse collection vehicle M1 is a refuse collection vehicle M that has passed through a collection route that collects refuse containing organic matter at a predetermined ratio or more. That is, the first refuse collection vehicle M1 carries the first refuse T1 determined or estimated to contain the organic matter at a predetermined ratio or more. The second garbage truck M2 is a garbage truck M that has passed through a collection route for collecting garbage containing less than a predetermined percentage of organic matter. That is, the second refuse collection vehicle M2 is equipped with the second refuse T2 that has been determined or estimated to contain the organic matter less than the predetermined ratio.

  The first garbage truck M1 and the second garbage truck M2 are, for example, a vehicle registration number (license plate), an identification number assigned to the garbage truck M, an operating company of the garbage truck M, and a garbage truck. The distinction can be made by self-report etc. by the driver of M. Also, when the garbage is carried into the garbage transfer facility 1A, the weight of the garbage truck M is weighed, and the first garbage truck M1 and the second garbage truck M2 are separated according to the weight. Is also good.

As shown in FIGS. 2 and 3, a compactor 31, which is a filling device, is provided as the filling device 30A. In addition, `` filling '' includes a concept of sending to a storage tank described below by free fall or the like without pressing or consolidating garbage, and `` stuffing '' is a kind of `` filling '' This is a concept of pressing or consolidating and sending it to a storage tank described later.
Only one compactor 31 is provided for the first hopper 11A and the second hopper 21A. The compactor 31 is arranged downstream of the first hopper 11A and the second hopper 21A. The compactor 31 includes a hollow box-shaped container 31a and a pusher (not shown) provided in the container 31a.

The compactor 31 is arranged so as to be connectable to the first storage tank 12A and the second storage tank 22A. The first storage tank 12A and the second storage tank 22A are arranged on a moving table 33. The first storage tank 12A and the second storage tank 22A can be alternatively arranged at a position facing the compactor 31 by moving the movable table 33 in the horizontal direction.
When the first refuse T1 is compressed and accommodated in the first storage tank 12A, the movement of the moving table 33 causes the first storage tank 12A to be disposed at a position facing the compactor 31. When the second refuse T2 is compressed and stored in the second storage tank 22A, the movement of the movable table 33 causes the second storage tank 22A to be disposed at a position facing the compactor 31. When arranged at the opposing position, the first storage tank 12A or the second storage tank 22A is connected to communicate with the inside of the compactor 31, respectively.

  The first storage tank 12A is provided corresponding to the first hopper 11A. The first storage tank 12A is a container 13 that can be connected to the compactor 31. The container 13 has, for example, a hollow box shape. The first storage tank 12A can store a larger amount of the first refuse T1 than the first refuse collection vehicle M1.

The compactor 31 packs the first waste T1 in the container 31a into the first storage tank 12A by pressure-feeding the first waste T1 with a pusher.
As shown in FIG. 2, the first storage tank 12 </ b> A can be mounted on a transport vehicle 80 and transferred. The transport vehicle 80 carries the first storage tank 12A filled with the first refuse T1, and transfers the first storage tank 12A to the container storage 5 installed in the refuse transfer facility 1A. In the container storage 5, a plurality of first storage tanks 12A can be stored.

  The second storage tank 22A is provided corresponding to the second hopper 21A. The second storage tank 22A is a container 23 that can be connected to the compactor 31. The container 23 has, for example, a hollow box shape. In the present embodiment, the container 23 has the same shape as the container 13 that is the first storage tank 12A. The second storage tank 22A can store a larger amount of the second refuse T2 than the second refuse collection vehicle M2.

  The compactor 31 packs the second refuse T2 contained in the container 31a into the second storage tank 22A by pressure feeding with a pusher. The second storage tank 22A can be mounted on a transport vehicle 80 and transported. The transport vehicle 80 transfers the second storage tank 22A filled with the second refuse T2 to the secondary treatment facility 2 (see FIG. 1) outside the premises of the refuse transfer facility 1A. The second waste T2 packed in the second storage tank 22A is subjected to secondary processing such as incineration and recycling in the secondary processing facility 2.

(Configuration of hydrothermal treatment equipment and methane fermentation equipment)
In the premises of the garbage transfer facility 1A, there are a hydrothermal treatment device 50 for solubilizing the inputted refuse (waste) by a hydrothermal reaction and discharging the slurry and the unsolubilized residue, and a hydrothermal treatment device 50. A methane fermentation apparatus 60 that produces methane gas by subjecting the obtained slurry to methane fermentation is provided.

The first refuse T1 stored in the first storage tank 12A is supplied to the hydrothermal treatment device 50. In the hydrothermal treatment apparatus 50, high-moisture-content waste containing a large amount of organic matter, such as the first refuse T1, is treated by a hydrothermal reaction. The hydrothermal treatment apparatus 50 includes a processing apparatus main body 51 having a hollow box shape, and a steam supply unit (not shown) for supplying high-temperature and high-pressure steam into the processing apparatus main body 51. At an upper portion of the processing apparatus main body 51, a processing apparatus hopper 53 for charging the first refuse T1 into the processing apparatus main body 51 is provided.
The first refuse T <b> 1 packed in the first storage tank 12 </ b> A is supplied from the processing apparatus hopper 53 into the processing apparatus main body 51 according to the processing state of the hydrothermal processing apparatus 50. A high-temperature and high-pressure steam is supplied by a steam supply unit (not shown) into the processing apparatus main body 51 into which the first refuse T1 is charged. The hydrothermal treatment device 50 causes the first refuse T1 to undergo a hydrothermal reaction under high temperature and high pressure steam under predetermined conditions.

  In the hydrothermal treatment apparatus 50, the first waste T1 is processed by the hydrothermal reaction, thereby generating the slurry 101 in which the organic matter contained in the first waste T1 is liquefied. In the hydrothermal treatment apparatus 50, substances that are not suitable for the hydrothermal reaction and substances that have not sufficiently undergone the hydrothermal reaction included in the first refuse T1 remain after the treatment by the hydrothermal reaction and are generated as the residue 102. . The substance not suitable for the hydrothermal reaction is, for example, an inorganic substance such as a metal. The hydrothermal treatment apparatus 50 separates the slurry 101 and the residue 102 and discharges them separately.

  The hydrothermal treatment device 50 is connected to the methane fermentation device 60 by a transfer pipe 70. The transport pipe 70 transports the slurry 101 discharged from the hydrothermal treatment device 50 to the methane fermentation device 60.

  The methane fermentation device 60 includes a fermentation tank 61 and a temperature adjustment unit (not shown). The methane fermentation device 60 accommodates the slurry 101 in a fermentation tank 61. The methane fermentation apparatus 60 ferments the slurry 101 by maintaining the slurry 101 in the fermentation tank 61 in a predetermined temperature environment by a temperature adjustment unit (not shown) to generate a gas containing methane gas. The generated gas (methane gas) is conveyed to a generator, a boiler, or the like by a pipeline or the like, and is used as a combustion gas.

In addition, the hydrothermal treatment device 50 is connected to the second hopper 21 </ b> A by the residual material conveyor 83. The residue 102 generated by the hydrothermal treatment device 50 is transported to the second hopper 21A by the residue transport conveyor 83. This remnant 102 is put into the second hopper 21A and is processed together with the second refuse T2.
Since the remnants 102 are conveyed to the second hopper 21A, they do not enter the hydrothermal treatment apparatus 50 again. Therefore, the hydrothermal treatment apparatus 50 can be operated efficiently.

  Note that the configuration for transporting the residuals 102 is not limited to the residuals transport conveyor 83. Any configuration may be used as long as the residue 102 can be transported to the second hopper 21A. Therefore, for example, the remnant 102 may be transported by the transport vehicle 80 or the feed pipe.

(Effects)
In the refuse transfer facility 1A, a first hopper 11A for receiving the first refuse T1 and a second hopper 21A for receiving the second refuse T2 are separately provided. Then, only the first refuse T1 determined or estimated to contain the organic matter at a predetermined ratio or more is stored in the first storage tank 12A, and is charged into the hydrothermal treatment apparatus 50. As a result, at the time of hydrothermal treatment in the hydrothermal treatment apparatus 50, the first refuse T1 containing a large amount of organic matter can be selectively introduced so that the second refuse T2 containing little organic matter is not included. As a result, a large amount of organic matter is charged into the hydrothermal treatment apparatus 50, and the hydrothermal treatment can be performed efficiently. Therefore, the efficiency of treating waste in the hydrothermal treatment apparatus 50 can be increased.

  In addition, since only the first refuse T1 is supplied to the hydrothermal treatment apparatus 50, a viewpoint of obtaining a predetermined amount of slurry as compared with the case where the first refuse T1 and the second refuse T2 are mixed and supplied. In this case, the capacity of the hydrothermal treatment apparatus 50 itself can be reduced. This makes it possible to reduce the size of the hydrothermal treatment apparatus 50 and to reduce the cost of introducing and maintaining the apparatus.

  Further, the second refuse T <b> 2 determined or estimated to contain the organic matter less than the predetermined ratio is not suitable for the hydrothermal treatment in the hydrothermal treatment apparatus 50. Such second waste T2 is not fed into the hydrothermal treatment apparatus 50, but is carried out from the waste transfer facility 1A to the secondary treatment facility 2. At this time, there is no need to carry out the first waste T1 to be treated by the hydrothermal treatment apparatus 50 to the secondary treatment facility 2. Therefore, the amount of garbage carried out to the secondary treatment facility 2 is reduced. As a result, the space for placing the garbage to be carried out to the secondary treatment facility 2 and the number of transport vehicles 80 required for carrying out the garbage can be reduced. Therefore, it is possible to reduce the cost of carrying out the second waste T2 from the waste transfer facility 1A to the secondary treatment facility 2.

  In the refuse transfer facility 1A, the hydrothermal treatment apparatus 50 discharges the slurry 101 obtained by the hydrothermal reaction and the residue 102 remaining after the treatment by the hydrothermal reaction. After that, the remnants 102 are put into the second hopper 21A. For this reason, the residue 102 is not fed into the hydrothermal treatment apparatus 50 again. Therefore, the hydrothermal treatment apparatus 50 can be operated efficiently.

  The filling device 30A of the refuse transfer facility 1A is a compactor 31. The first storage tank 12 </ b> A and the second storage tank 22 </ b> A are containers 13, 23 that can be connected to one compactor 31 and can be transferred by the transport vehicle 80. By sharing the compactor 31 between the first storage tank 12A and the second storage tank 22A, the number of the compactors 31 can be reduced. Thereby, cost reduction can be achieved.

  The container 13 as the first storage tank 12A is filled with the first refuse T1 compressed by the compactor 31. Thereby, the first refuse T1 can be stored in a reduced volume state until it is put into the hydrothermal treatment apparatus 50. Similarly, the container 23 as the second storage tank 22A is filled with the second refuse T2 compressed by the compactor 31. Therefore, the second refuse T2 can be stored with a reduced volume. Thus, the first refuse T1 and the second refuse T2 can be efficiently stored in the first storage tank 12A and the second storage tank 22A. Therefore, the number of containers 13 and 23 for storing the first refuse T1 and the second refuse T2 can be reduced. As a result, the site area required for the garbage transfer facility 1A can be reduced. Thereby, cost reduction can be achieved.

  The refuse transfer facility 1A further includes a methane fermentation device 60, a hydrothermal treatment device 50, and a transport pipe 70. Therefore, the hydrothermal reaction and the methane fermentation can be performed in the refuse transfer facility 1A, that is, in the same facility. Since the hydrothermal treatment device 50 and the methane fermentation device 60 are provided in the same facility, the time and cost for transporting the slurry 101 from the hydrothermal treatment device 50 to the methane fermentation device 60 can be reduced.

(Modification of First Embodiment)
In the first embodiment, the methane fermentation device 60, the hydrothermal treatment device 50, and the transfer pipe 70 are provided in the refuse transfer facility 1A. However, the garbage relay facility 1A is not limited to such a configuration. For example, as shown in FIG. 4, the methane fermentation device 60, the hydrothermal treatment device 50, and the transport pipe 70 may be provided in a facility B provided separately from the waste transfer facility 1A.

  In this case, the first storage tank 12A stored in the container storage 5 is transferred to the hydrothermal treatment device 50 in the facility B by the transport vehicle 80 according to the processing status of the hydrothermal treatment device 50. The first refuse T1 in the first storage tank 12A is put into the processing apparatus main body 51 from the processing apparatus hopper 53. The first refuse T1 charged into the hydrothermal treatment apparatus 50 is subjected to hydrothermal treatment by a hydrothermal reaction, as in the above-described embodiment, so that a slurry 101 and a residue 102 are generated from the first refuse T1. . The slurry 101 is subjected to a fermentation treatment in the methane fermentation apparatus 60, so that a gas containing methane gas is generated from the slurry 101. In addition, the remnants 102 are transferred to the refuse transfer facility 1A by the transport vehicle 80 or the like and thrown into the second hopper 21A. Then, the residue 102 is processed together with the second refuse T2 without using the hydrothermal treatment apparatus 50.

<Second embodiment>
Next, a second embodiment will be described. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals in the drawings, and description thereof will be omitted. The second embodiment is different from the first embodiment in that the second embodiment has first and second rotating drums which also serve as a filling device and a storage tank.

(Garbage relay facility)
As shown in FIG. 5, the refuse transfer facility 1B includes a first hopper 11B, a second hopper 21B, a first rotating drum 91B, and a second rotating drum 92B.

  The first hopper 11B receives the first refuse T1 input from the first refuse collection vehicle M1. The first hopper 11B is connected to the first rotating drum 91B. The first hopper 11B sends the first refuse T1 to the first rotating drum 91B.

  The second hopper 21B receives the second refuse T2 input from the second refuse collection vehicle M2. The second hopper 21B is connected to the second rotating drum 92B. The second hopper 21B sends the second dust T2 to the second rotating drum 92B.

  As shown in FIG. 6, the first rotating drum 91B includes a drum housing 93 and internal blades 95. Further, the second rotating drum 92B includes a drum housing 94 and internal blades 96. The drum housing 94 has the same shape as the drum housing 93 of the first rotating drum 91B. Further, the internal blade 96 has the same shape as the internal blade 95 of the first rotating drum 91B. Therefore, here, the first rotary drum 91B will be described as an example.

  The drum housing 93 has a cylindrical shape extending along the central axis O. In the drum housing 93, an input port 93a facing the first hopper 11B is formed on the first side in the direction of the central axis O. The drum housing 93 has a reduced diameter portion 93b having a reduced inner diameter on the second side in the direction of the central axis O. A discharge port 93c is formed on the secondmost side of the reduced diameter portion 93b in the direction of the central axis O. An openable and closable door 93d is attached to the discharge port 93c. The drum housing 93 is supported by a plurality of support rollers 97 so as to be rotatable around a central axis O with respect to a pedestal 98 fixed on a foundation. The drum housing 93 is rotatable around a central axis O with respect to the foundation by a drive source (not shown) such as a motor.

  The internal blades 95 send the dust put into the drum housing 93 from the inlet 93a to the outlet 93c. The inner blade 95 has a spiral shape in the drum housing 93. The outer peripheral end of the inner blade 95 is fixed to the inner wall of the drum housing 93.

  In the first rotating drum 91B, first dust T1 is sent from the first hopper 11B into the drum housing 93 through the charging port 93a. In the first rotary drum 91B, the first dust T1 in the drum housing 93 is sent toward the discharge port 93c by the internal blades 95 by the rotation of the drum housing 93. Then, as the amount of the first refuse T1 put into the drum housing 93 increases, the first refuse T1 is sent while being compressed. Thus, the rotating inner blade 95 is a filling device, and serves as the first filling device 34 (first filling device) for compressing the first refuse T1 received by the first hopper 11B. Function. Further, the drum housing 93 containing the compressed first waste T1 functions as a first storage tank 12B capable of storing the first waste T1.

  Similarly, in the second rotating drum 92B, the second refuse T2 fed from the second hopper 21B into the inlet 93a is sent to the outlet 93c while being compressed. Thus, in the second rotating drum 92B, the rotating inner blade 95 is a filling device, and the second packing device 35 for compressing the second refuse T2 received by the second hopper 21B. It functions as (second filling device). Further, the drum housing 94 that is storing the compressed second waste T2 functions as a second storage tank 22B that can store the second waste T2.

  The first rotating drum 91B and the second rotating drum 92B have the same-shaped drum housing 94 and internal blades 96, but are not limited to such a configuration. That is, the first rotary drum 91B and the second rotary drum 92B may have drum housings and internal blades of different sizes and shapes.

  In the refuse transfer facility 1B, as shown in FIG. 5, a transporting means 85 such as a conveyor for transporting the first refuse T1 to the hydrothermal treatment apparatus 50 is disposed near the discharge port 93c of the first rotary drum 91B. Is done. In the first rotating drum 91B, the opening / closing door 93d is opened when a fixed amount of the compressed first refuse T1 is stored. As a result, the compressed first refuse T1 is sent from the drum housing 93 to the transporting means 85. The first refuse T1 that has been sent out is transported by the transporting means 85 to the hydrothermal treatment apparatus 50 provided in the refuse transfer facility 1B. In the hydrothermal treatment apparatus 50, the slurry 101 and the residue 102 are generated from the first refuse T1 by performing the hydrothermal treatment by the hydrothermal reaction as in the first embodiment. The slurry 101 is sent to the methane fermentation apparatus 60 and subjected to fermentation treatment, whereby a gas containing methane gas is generated from the slurry 101. Further, the residue 102 is transferred to the second hopper 21B by the residue transport conveyor 83, and is processed together with the second waste T2.

  A transport vehicle 80 for transporting the second refuse T2 is disposed near the discharge port 93c of the second rotating drum 92B. In the second rotating drum 92B, the opening / closing door 93d is opened when a fixed amount of the compressed second refuse T2 is stored. As a result, the compressed second waste T2 is sent out from the drum housing 94 to the transport vehicle 80. The second refuse T2 sent out is transferred by the transport vehicle 80 to the secondary treatment facility 2 outside the premises of the refuse transfer facility 1B.

(Effects)
In the refuse relay facility 1B, the first filling device 34 (first filling device), which is the filling device 30B, and the first storage tank 12B are configured to be integrated, and the first rotary drum 91B is formed. It is formed. Further, the second filling device 35 (second filling device), which is the filling device 30B, and the second storage tank 22B are configured so as to be integrated with each other to form a second rotating drum 92B. The first rotary drum 91B and the second rotary drum 92B store the refuse (waste) input by being rotated while compressing the refuse.

  The refuse transfer facility 1B can store the first refuse T1 in a compressed state with the first rotating drum 91B. For this reason, the waste T1 can be stored in a state where the volume of the first waste T1 before being put into the hydrothermal treatment apparatus 50 is reduced. In addition, the refuse transfer facility 1B can store the second refuse T2 in a state where the second refuse T2 is compressed by the second rotary drum 92B. Thereby, the second refuse T2 before being transferred to the secondary treatment facility 2 can be stored in a state where the volume is reduced.

(Modification of Second Embodiment)
In the second embodiment, the garbage relay facility 1B is provided with one first rotating drum 91B and one second rotating drum 92B, but the number of each may be plural.
Also in the second embodiment, as in the modification of the first embodiment, the methane fermentation device 60, the hydrothermal treatment device 50, and the transport pipe 70 are provided in a facility provided separately from the refuse transfer facility 1B. May be provided.

(Other embodiments)
As described above, the embodiments of the present disclosure have been described in detail with reference to the drawings. However, the specific configuration is not limited to the embodiments and includes a design change or the like without departing from the gist of the present disclosure. .

  For example, the movement of the first refuse T1 and the second refuse T2 between the devices is not limited to the use of the transport vehicle 80. Instead of the transport vehicle 80, another transport means such as a conveyor may be provided.

  Further, in the embodiment, the hydrothermal treatment device 50 and the methane fermentation device 60 are connected by the transfer pipe 70, but the present invention is not limited to such a configuration. For example, the hydrothermal treatment device 50 and the methane fermentation device 60 may be separately provided at separate positions, and the slurry 101 generated by the hydrothermal treatment device 50 may be transported to the methane fermentation device 60 by a transportation means such as a vehicle. Further, the slurry 101 generated by the hydrothermal treatment device 50 may not be treated by the methane fermentation device 60. In this case, the slurry 101 can be used as, for example, an organic compost. Further, the slurry 101 may be treated by incineration.
