Summary of the Invention

Problems to be Solved by the Invention

[0004] Unlike batch-type furnace equipment, continuous furnace equipment needs to ensure a distance for moving biomass raw materials and products in the process until the products are manufactured. Therefore, when the amount of raw materials and products increases, it is necessary to enlarge the furnace equipment. However, for example, when the furnace equipment is mounted on a vehicle or the like to make it a mobile furnace equipment, or when a stationary furnace equipment is loaded on a vehicle or the like and moved, if there are spatial restrictions on the place where the furnace equipment is installed, the size of the furnace equipment is limited, and the production amount of the products will be restricted. On the other hand, in order to process a large amount of raw materials in a short time and manufacture a large amount of products, continuous furnace equipment is more suitable than batch-type furnace equipment.

[0005] Also, for example, when transporting the completed products, mounting or loading the furnace equipment on a vehicle or the like, there may be a risk of loading the smoked carbide on the vehicle, and if the smoked carbide is left unattended, it may reignite and turn into ash.

[0006] The present disclosure has been made in view of such circumstances, and an object thereof is to provide a furnace facility that can continuously perform at least carbonization to fire extinguishing in one furnace facility and has a structure that is easy to compactify.

Means for Solving the Problems

[0007] In order to solve the above problems, the furnace facility of the present disclosure employs the following means. A furnace facility according to an aspect of the present disclosure includes a carbonization furnace that produces a carbide by carbonizing a carbide material, and a fire extinguishing chamber that extinguishes the carbide discharged from the carbonization furnace, and the fire extinguishing chamber is adjacent to the carbonization furnace.

Effects of the Invention

[0008] According to the present disclosure, it is possible to continuously perform at least carbonization to fire extinguishing in one furnace facility, and it is possible to provide a furnace facility having a structure that is easy to compactify.

Modes for Carrying Out the Invention

[0010] Hereinafter, a furnace facility according to an embodiment of the present disclosure will be described with reference to the drawings.

[0011] <Structure of the furnace equipment> The furnace equipment 100 according to an embodiment of the present disclosure is a carbonization furnace equipment / reactor equipment that manufactures carbide W2 such as biochar and biofuel using carbide W1 such as woody biomass as a raw material and carbide W2 as a product. Hereinafter, the furnace equipment 100 according to an embodiment of the present disclosure will be described by taking the furnace equipment 100 as a carbonization furnace equipment as an example.

[0012] The furnace equipment 100 is a continuous carbonization furnace equipment. As shown in FIG. 1, the furnace equipment 100 includes, for example, a carbonization furnace 111 and a fire extinguishing chamber 112. Further, the furnace equipment 100 may further include a drying chamber 113. The carbonization furnace 111 is a self-igniting furnace that manufactures carbide W2 by carbonizing carbide W1 by burning carbide W1 in an oxygen-deficient environment. The fire extinguishing chamber 112 is a chamber that extinguishes (stops the combustion reaction) and cools the carbide W2 discharged from the carbonization furnace 111. The drying chamber 113 is a chamber that dries the carbide W1 supplied from the outside and before being charged into the carbonization furnace 111.

[0013] These carbonization furnace 111, fire extinguishing chamber 112, and drying chamber 113 are defined by a container 101 and partition walls 102 and 103 provided inside the container 101. That is, the furnace equipment 100 includes a container 101, a partition wall 102, and a partition wall 103, and these define the carbonization furnace 111, the fire extinguishing chamber 112, and the drying chamber 113.

[0014] The container 101 is a substantially rectangular parallelepiped-shaped portion, and a space is formed inside. Inside the container 101, a partition wall 102 extending vertically and a partition wall 103 extending front and back are provided. The partition wall 102 is located substantially at the center in the front-rear direction orthogonal to the vertical direction and is connected to the upper and lower portions of the container 101. That is, the partition wall 102 divides the space inside the container 101 into front and back. The partition wall 103 is located approximately at the center in the vertical direction and is connected to the front part of the container 101 and the partition wall 102. That is, the partition wall 103 divides the front space inside the container 101 vertically. At this time, the rear space inside the container 101 is used as the carbonization furnace 111, the front and lower space inside the container 101 is used as the fire extinguishing chamber 112, and the front and upper space inside the container 101 is used as the drying chamber 113. That is, the fire extinguishing chamber 112 and the drying chamber 113 are adjacent to each other vertically (the fire extinguishing chamber 112 is below and the drying chamber 113 is above), and the set of the fire extinguishing chamber 112 and the drying chamber 113 and the carbonization furnace 111 are adjacent to each other front and back.

[0015] By arranging the carbonization furnace 111, the fire extinguishing chamber 112, and the drying chamber 113 in this way, the fire extinguishing chamber 112 and the drying chamber 113 can be arranged by utilizing the vertical space. Also, the material to be carbonized W1 can be introduced into the carbonization furnace 111 in a form of dropping from the drying chamber 113, and the carbide W2 produced at the lower part of the carbonization furnace 111 can be discharged into the fire extinguishing chamber 112.

[0016] The vertically extending partition wall 102 is provided with an upper opening 102a and a first lower opening (first opening) 102b. The upper opening 102a is an opening located at the upper part of the partition wall 102 and communicates the carbonization furnace 111 and the drying chamber 113. The first lower opening 102b is an opening located at the lower part of the partition wall 102 and communicates the carbonization furnace 111 and the fire extinguishing chamber 112.

[0017] The container 101 is provided with a second lower opening (second opening) 101b. The second lower opening 101b is an opening located at the front and lower part of the container 101 and communicates the fire extinguishing chamber 112 and the outside of the container 101 (that is, the outside of the furnace equipment 100). The position of the second lower opening 101b substantially coincides with the position of the first lower opening 102b in the vertical direction.

[0018] A first gate (first opening / closing mechanism) 121 is provided at the first lower opening 102b. A second lower opening 101b is provided with a second gate (second opening / closing mechanism) 122. The first gate 121 is a gate that closes or opens the first lower opening 102b. That is, the first gate 121 can connect or separate the carbonization furnace 111 and the fire extinguishing chamber 112. The second gate 122 is a gate that closes or opens the second lower opening 101b. That is, the second gate 122 can connect or separate the fire extinguishing chamber 112 and the outside of the container 101. Thereby, the temperature environment and oxygen atmosphere in the fire extinguishing chamber 112 can be blocked from the outside.

[0019] An intake part 111a is provided on the side surface at the lower part of the carbonization furnace 111. The intake part 111a is a part for taking air from the outside of the container 101 (i.e., the outside of the furnace equipment 100) into the carbonization furnace 111, and can connect the outside of the container 101 and the carbonization furnace 111. An exhaust part 113a is provided on the side surface of the drying chamber 113. The exhaust part 113a is a part for discharging exhaust gas (which may contain pyrolysis gas as a component. The same applies hereinafter) from the drying chamber 113 to the outside of the container 101 (i.e., the outside of the furnace equipment 100), and can connect the drying chamber 113 and the outside of the container 101. Here, the position of the drying chamber 113 corresponds to the upper part of the carbonization furnace 111 in the vertical direction. Therefore, the position of the exhaust part 113a also corresponds to the upper part of the carbonization furnace 111 in the vertical direction.

[0020] Dampers (not shown) are respectively installed in the intake part 111a and the exhaust part 113a, and the amount of gas passing through the carbonization furnace 111 and the drying chamber 113 can be adjusted by their opening degrees. Also, an induced draft fan (not shown) may be installed in the exhaust part 113a or in the vicinity of the exhaust part 113a to force ventilation.

[0021] A first conveyor (first conveying device) 131 is installed in the carbonization furnace 111. The first conveyor 131 is a device on which the material to be carbonized W1 and / or the carbide W2 (hereinafter also referred to as the "conveyed material") is placed and which conveys the carbide W2 toward the fire extinguishing chamber 112 (toward the front of the furnace equipment 100). The first conveyor 131 is driven by a driving part such as a motor (not shown). The first conveyor 131 is installed so that its conveying surface is substantially horizontal. A second conveyor (second conveying device) 132 is installed in the fire extinguishing chamber 112. The second conveyor 132 is a device on which the carbide W2 is placed and which conveys the carbide W2 toward the outside of the container 101 (toward the front of the furnace equipment 100). The second conveyor 132 is driven by a driving part such as a motor (not shown). The second conveyor 132 is installed so that its conveying surface is substantially horizontal. The height of the conveying surface of the second conveyor 132 substantially coincides with the height of the conveying surface of the first conveyor 131. A third conveyor (third conveying device) 133 is installed in the drying chamber 113. The third conveyor 133 is a device on which the material to be carbonized W1 is placed and which conveys the material to be carbonized W1 toward the carbonization furnace 111 (toward the rear of the furnace equipment 100). The third conveyor 133 is driven by a driving part such as a motor (not shown). The third conveyor 133 is installed so that its conveying surface is substantially horizontal.

[0022] A raw material input part 141 is provided in the drying chamber 113. The raw material input part 141 is a device for inputting the material to be carbonized W1 as a raw material from the outside of the container 101 into the drying chamber 113. The lower end of the raw material input part 141 is an opening through which the material to be carbonized W1 is discharged, and is located above the rear part (front part when viewed from the furnace equipment 100) in the advancing direction of the third conveyor 133.

[0023] The furnace equipment 100 may be provided with at least one of an inert gas supply device 150 for supplying an inert gas (for example, nitrogen gas) to the fire extinguishing chamber 112 and a water spraying device 160 for spraying water into the fire extinguishing chamber 112. The inert gas supply device 150 has an inert gas supply pipe 151 and a regulating valve 152, and is configured such that the flow rate of the inert gas supplied to the fire extinguishing chamber 112 through the inert gas supply pipe 151 can be adjusted by the regulating valve 152. The inert gas is supplied to the inert gas supply pipe 151 from a device (not shown). The water spraying device 160 has a water supply pipe 161 and a regulating valve 162, and is configured such that the flow rate of the water sprayed to the fire extinguishing chamber 112 through the water supply pipe 161 can be adjusted by the regulating valve 162. The water is supplied to the water supply pipe 161 from a device (not shown).

[0024] The furnace facility 100 may be provided with a control unit 170. The control unit 170 is a device that executes control necessary for the operation of the furnace facility 100, such as control of each device (each gate, each transfer device, each valve, each measurement unit, and each analysis unit) provided in the furnace facility 100, processing of information acquired from each device, and relaying of signal transmission and reception between each device. The control unit 170 (Controller) includes, for example, a CPU (Central Processing Unit: processor), a main memory device (Main Memory), a secondary storage device (Secondary storage: memory), etc. Further, the control unit 170 may include a communication unit for transmitting and receiving information to and from other devices. The main memory device is composed of a writable memory such as a cache memory, a RAM (Random Access Memory), etc., and is used as a work area for reading the execution program of the CPU, writing processing data by the execution program, etc. The secondary storage device is a non-transitory computer-readable recording medium (non-transitory computer readable storage medium). The secondary storage device is, for example, a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, etc. A series of processes for realizing various functions are stored in a secondary storage device in the form of a program as an example. The CPU reads this program into the main memory device and executes information processing and arithmetic operations, thereby realizing various functions. Note that the program may be applied in a form where it is pre-installed in the secondary storage device, a form where it is provided in a state stored in a computer-readable storage medium, a form where it is distributed via wired or wireless communication means, etc. A computer-readable storage medium is a magnetic disk, magneto-optical disk, CD-ROM, DVD-ROM, semiconductor memory, etc.

[0025] <Regarding the manufacture of the product> In the furnace facility 100 configured as described above, the product (carbide W2) is manufactured as follows.

[0026] First, the carbide W1 as a raw material is input from the raw material input section 141 into the drying chamber 113. The input carbide W1 falls onto the rear part in the traveling direction of the driving third conveyor 133 below. While the carbide W1 is being conveyed by the third conveyor 133 to the front part in the traveling direction (the part close to the carbonization furnace 111), the carbide W1 is dried. The drying is performed by the high-temperature exhaust gas led from the carbonization furnace 111 to the drying chamber 113 through the upper opening 102a. The carbide W1 that has reached the front part in the traveling direction of the third conveyor 133 and has finished drying is input into the carbonization furnace 111 through the upper opening 102a.

[0027] Note that when the carbide W1 that has fallen onto the rear part in the traveling direction of the driving third conveyor 133 has spread over the entire conveying surface, the input of the carbide W1 from the raw material input section 141 is stopped and the third conveyor 133 is stopped, and in this state, the carbide W1 is dried. After drying, the third conveyor 133 may be driven again to input the carbide W1 into the carbonization furnace 111.

[0028] The material to be carbonized W1 fed into the carbonization furnace 111 falls downward toward the first conveyor 131 below. The material to be carbonized W1 stacked on the first conveyor 131 burns in an oxygen-deficient environment and is carbonized by the heat generated by the combustion. At this time, among the stacked materials to be carbonized W1, the material to be carbonized W1 whose upper part is less carbonized and the material to be carbonized W1 whose lower part is more carbonized (carbide W2) are formed. That is, the upper part is the self-ignition area A1, and the lower part is the carbonization area A2. In other words, the inside of the carbonization furnace 111 includes the self-ignition area A1 and the carbonization area A2, the carbonization area A2 is located on the conveying surface of the first conveyor 131, and the self-ignition area A1 is located above the carbonization area A2.

[0029] The high-temperature exhaust gas generated by the combustion and carbonization of the material to be carbonized W1 moves to the upper part of the carbonization furnace 111. At this time, after the high-temperature exhaust gas is guided from the carbonization furnace 111 to the drying chamber 113 through the upper opening 102a as a gas inlet, it is discharged from the drying chamber 113 to the outside of the container 101 through the exhaust part 113a. By this exhaust gas flow, the material to be carbonized W1 in the drying chamber 113 is dried. Note that an opening (another gas inlet) different from the upper opening 102a may be provided in the partition wall 102 so that more high-temperature exhaust gas is likely to be guided to the drying chamber 113.

[0030] When dropping the material to be carbonized W1 toward the first conveyor 131, from the viewpoints of efficient and uniform combustion and carbonization, it is preferable to form a layer of the material to be carbonized W1 with a uniform thickness on the conveying surface of the first conveyor 131. Therefore, the furnace equipment 100 may include a chute 142. The chute 142 has one end (rear end) and the other end (front end) located below the rear end, and is a component that guides the material to be carbonized W1 moving from the rear end to the front end (the material to be carbonized W1 flowing due to the inclination) to a predetermined position.

[0031] The rear end of the chute 142 is located immediately adjacent to the front part in the advancing direction of the third conveyor 133. Accordingly, the carbide W1 conveyed by the third conveyor 133 can be smoothly transferred onto the chute 142.

[0032] The front end of the chute 142 is configured to be able to arbitrarily change its position above the first conveyor 131. Specifically, the front end of the chute 142 may move in the vertical direction, may move in the front-rear direction, or may move in the depth direction (front / rear). As shown in FIG. 2, for example, the front end of the chute 142 may move from the front to the rear so as to be located at the front in the conveying direction of the first conveyor 131 at the start of the charging of the carbide W1 and to be located at the rear in the conveying direction of the first conveyor 131 at the end of the charging of the carbide W1.

[0033] Accordingly, the dried carbide W1 conveyed by the third conveyor 133 can be dropped at an arbitrary position on the first conveyor 131, and a layer of carbide W1 with a uniform thickness can be formed on the conveying surface of the first conveyor 131. Further, the layer of carbide W1 with a uniform thickness becomes a layer of carbide W2 with a uniform thickness as combustion and carbonization progress.

[0034] As shown in FIG. 1, when the carbonization of the carbide W1 in the carbonization area A2 is completed (that is, when the carbide W2 is formed on the conveying surface of the first conveyor 131), the first gate 121 is opened with the second gate 122 closed, and the first conveyor 131 and the second conveyor 132 are driven.

[0035] At this time, the position of the first lower opening 102b corresponds to the position of the carbonization area A2 in the vertical direction.

[0036] Further, as shown in FIG. 2, the furnace facility 100 may include a separation plate 143. The separation plate 143 is a member for preventing the conveyed material above a certain height line Lh from being conveyed toward the first lower opening 102b. In other words, the separation plate 143 is a member for allowing the conveyed material below a certain height line Lh to be conveyed toward the first lower opening 102b.

[0037] The separation plate 143 is, for example, as follows. The separation plate 143 is a member extending from the partition wall 102 toward the carbonization furnace 111, and has a base end portion 143a attached to the partition wall 102 and a tip end portion 143b inclined downward. The tip end portion 143b is connected to the base end portion 143a and is configured such that the inclination angle can be arbitrarily changed. The position of the height line Lh is determined by the position of the tip (the lowermost end) of the tip end portion 143b. The position of the height line Lh can be adjusted by changing the inclination angle of the tip end portion 143b or moving the separation plate 143 (vertical movement). The position of the height line Lh is set, for example, at a position where the conveyed material placed on the first conveyor 131 is separated into the carbide W2 below and the material to be carbonized W1 above.

[0038] With these configurations, only the carbide W2 will transfer to the second conveyor 132 through the first lower opening 102b and be discharged into the fire extinguishing chamber 112.

[0039] As shown in FIG. 1, the first lower opening 102b is a cut gate, and the opening area is known in advance. Therefore, the control unit 170 can calculate the discharge amount of the carbide W2 and the production amount of the product based on the conveyance speed set for the first conveyor 131 and the opening area of the first lower opening 102b. Further, the control unit 170 may determine the input amount of the material to be carbonized W1 in consideration of the balance with the discharge amount of the carbide W2.

[0040] When the discharge of carbide W2 is completed (i.e., when carbide W2 is transferred from the first conveyor 131 to the second conveyor 132), stop the first conveyor 131 and the second conveyor 132 and close the first gate 121.

[0041] After the discharge of carbide W2 is completed, the carbide W1 that was in the spontaneous combustion area A1 before the discharge moves to the carbonization area A2.

[0042] During or after the discharge of carbide W2, due to the driving of the first conveyor 131 and the blocking of the conveyed material by the cut gate or the separation plate 143 of the first lower opening 102b, the carbide W1 may be biased towards the front part in the conveying direction of the first conveyor 131. Therefore, as shown in FIG. 3, the furnace facility 100 may be provided with at least one baffle plate 144. The baffle plate 144 is a plate extending in the vertical direction and is installed at least in the spontaneous combustion area A1. In the case of FIG. 3, two baffle plates 144 arranged in the front-rear direction at substantially the same height position are installed. Thereby, even if the first conveyor 131 is driven, it becomes difficult for the carbide W1 to be biased towards the front part in the conveying direction of the first conveyor 131. Also, if the bias of the carbide W1 occurs, the bias may be evened out by reversing the first conveyor 131. When the distance between the partition wall 102 and the front baffle plate 144 and the distance between the front baffle plate 144 and the rear baffle plate 144 are L, for example, by reversing the first conveyor 131 so that the conveying surface returns by L / 2, the biased carbide W1 comes into contact with the baffle plate 144 and collapses, and the bias of the carbide W1 can be eliminated.

[0043] After the discharge of carbide W2 is completed, new carbide W1 is charged into the spontaneous combustion area A1 where there is spatial room. At this time, if the bias of the carbide W1 caused by the driving of the first conveyor 131 occurs, the position of the front end of the chute 142 may be adjusted to charge the carbide W1 into the part where the carbide W1 is less. Then, again, combustion in the self-ignition area A1 and carbonization in the carbonization area A2 will proceed.

[0044] During the discharge of the carbide W2 from the carbonization furnace 111, the carbide W1 may be charged into the carbonization furnace 111 from the drying chamber 113, or the charging may be stopped, and it is appropriately selected based on the amount of the carbide W1 stacked in the self-ignition area A1 and the carbonization area A2.

[0045] By closing the first gate 121 and the second gate 122, the temperature environment and oxygen atmosphere in the fire extinguishing chamber 112 are in a state of being blocked from the outside. The carbide W2 in such a fire extinguishing chamber 112 is automatically extinguished and cooled when the fire extinguishing chamber 112 falls into a low-oxygen state.

[0046] At this time, by supplying an inert gas to the fire extinguishing chamber 112 by the inert gas supply device 150, the oxygen concentration can be forcibly and quickly reduced. Also, by spraying water into the fire extinguishing chamber 112 by the water spraying device 160, it is possible to forcibly and quickly extinguish the fire and reduce the temperature. Note that the inert gas supply device 150 and the water spraying device 160 may be used separately or in combination.

[0047] When the fire extinguishing and cooling of the carbide W1 are completed, the second gate 122 is opened, and the second conveyor 132 is driven to discharge the carbide W2 as a product from the fire extinguishing chamber 112 to the outside of the container 101. When there is no more carbide W2 on the second conveyor 132 and the discharge of the carbide W2 is completed, the second conveyor 132 is stopped and the second gate 122 is closed. As a result, the fire extinguishing chamber 112 is in a state where it can receive the carbide W2 again.

[0048] <Regarding the control of the second gate> A fire extinguishing chamber thermometer 172a may be provided in the fire extinguishing chamber 112. The fire extinguishing chamber thermometer 172a is a means for measuring the temperature of the fire extinguishing chamber 112.

[0049] Based on the measured value of the fire extinguishing chamber thermometer 172a, the control unit 170 can open the second gate 122 or drive the second conveyor 132.

[0050] Specifically, after the carbide W2 is discharged from the carbonization furnace 111 to the fire extinguishing chamber 112, when the temperature of the sealed fire extinguishing chamber 112 becomes equal to or lower than a predetermined temperature, the control unit 170 determines that the carbide W2 has been extinguished and sufficiently cooled, opens the second gate 122, and then can drive the second conveyor 132. The "sufficiently cooled" mentioned here means a state in which the temperature of the carbide W2 has been reduced to a temperature at which there is no risk of re-ignition even if the carbide W2 is discharged from the fire extinguishing chamber 112. Thereby, the carbide W2 with no risk of re-ignition can be discharged from the fire extinguishing chamber 112.

[0051] <Regarding the control of the conveyor and the raw material input unit> The carbonization furnace 111 may be provided with at least any one of a gas thermometer 171a, a gas analyzer 171b, and a conveyed material analyzer 171c. The gas thermometer 171a is a means for measuring the temperature of the exhaust gas (gas generated by the combustion and carbonization of the carbide W1) in the carbonization furnace 111. The gas analyzer 171b is a means for analyzing the components of the exhaust gas. The "components" mentioned here are, for example, hydrocarbons such as water vapor, carbon monoxide, hydrogen, carbon dioxide, and methane. The conveyed material analyzer 171c is a means for analyzing the components of the carbide W1 and / or the carbide W2. The "components" mentioned here are the water content, fixed carbon, volatile matter, etc.

[0052] At least any one of the conveying speeds of the first conveyor 131, the second conveyor 132, and the third conveyor 133 and the amount of the carbide W1 input from the raw material input unit 141 may be adjusted based on at least any one of the measured values and analysis results of the gas thermometer 171a, the gas analyzer 171b, and the conveyed material analyzer 171c.

[0053] Specifically, the control unit 170 may adjust at least any one of the conveyance speeds of the first conveyor 131, the second conveyor 132, and the third conveyor 133 and the amount of the carbide W1 input from the raw material input unit 141 based on the measurement values and analysis results of the gas thermometer 171a and / or the gas analyzer 171b. For example, based on the measurement values and analysis results of the gas thermometer 171a and / or the gas analyzer 171b, at least one of the conveyance speeds of the first conveyor 131, the second conveyor 132, and the third conveyor 133 can be increased / reduced, at least one of the stop times of the first conveyor 131, the second conveyor 132, and the third conveyor 133 can be extended, or the input amount of the carbide W1 can be increased / reduced.

[0054] Further, the control unit 170 may adjust at least any one of the conveyance speeds of the first conveyor 131, the second conveyor 132, and the third conveyor 133 and the amount of the carbide W1 input from the raw material input unit 141 based on the analysis result of the conveyed material analyzer 171c. For example, based on the analysis result of the conveyed material analyzer 171c, the optimum reaction time for the carbonization of the carbide W1 in the carbonization furnace 111 is identified, and based on the identified reaction time, at least one of the conveyance speeds of the first conveyor 131, the second conveyor 132, and the third conveyor 133 can be increased / reduced, at least one of the stop times of the first conveyor 131, the second conveyor 132, and the third conveyor 133 can be extended, or the input amount of the carbide W1 can be increased / reduced.

[0055] Note that at least any one of a gas thermometer 173a, a gas analyzer 173b, and a conveyed material analyzer 173c may be provided in the drying chamber 113 to perform similar control.

[0056] As shown in FIG. 4, the furnace facility 100 may be mounted / loaded on, for example, a vehicle 10. Therefore, the furnace facility 100 may be provided with a connection part (not shown) used for connection to the vehicle 10 when mounted on the vehicle. Also, as shown in FIG. 5, according to the size of the vehicle 10, a plurality of furnace facilities 100 may be mounted / loaded on the vehicle 10.

[0057] According to the furnace facility 100 according to the present embodiment, the following effects can be obtained. Since it includes the carbonization furnace 111 and the fire extinguishing chamber 112, at least from carbonization to fire extinguishing can be continuously performed in one furnace facility 100. Also, since the fire extinguishing chamber 112 is adjacent to the carbonization furnace 111, the furnace facility 100 capable of performing at least from carbonization to fire extinguishing can be made compact, and for example, it can be made into a furnace facility 100 suitable for vehicle mounting.

[0058] Moreover, a drying chamber 113 may be provided. Since the drying chamber 113 is adjacent to the fire extinguishing chamber 112 above the fire extinguishing chamber 112, the drying chamber 113 and the fire extinguishing chamber 112 can be arranged by utilizing the space in the vertical direction. Also, since the set of the drying chamber 113 and the fire extinguishing chamber 112 is adjacent to the carbonization furnace 111 in a direction orthogonal to the vertical direction, the carbide W1 can be introduced into the carbonization furnace 111 in a form of dropping from the drying chamber 113 arranged above, and the carbide W2 produced at the lower part of the carbonization furnace 111 can be efficiently discharged to the fire extinguishing chamber 112 arranged below.

[0059] Also, since the carbonization furnace 111 includes the self-ignition area A1 and the carbonization area A2 located below the self-ignition area A1 inside, it becomes easier to introduce the carbide W1 from the drying chamber 113 into the self-ignition area A1, and it becomes easier to discharge the carbide W2 from the carbonization area A2 to the fire extinguishing chamber 112.

[0060] Also, since the position of the first lower opening 102b communicating between the carbonization furnace 111 and the fire extinguishing chamber 112 corresponds to the position of the carbonization area A2 of the carbonization furnace 111, only the carbide W2 can be efficiently discharged from the carbonization furnace 111 to the fire extinguishing chamber 112.

[0061] In addition, since it is provided with an exhaust part 113a provided in the drying chamber 113 and an upper opening 102a serving as a gas inlet that communicates between the carbonization furnace 111 and the drying chamber 113 and guides gas from the carbonization furnace 111 to the drying chamber 113, in a configuration where the drying chamber 113 is disposed above, the high-temperature gas (exhaust gas and / or pyrolysis gas) generated in the carbonization furnace 111 can be guided from the gas inlet to the drying chamber 113 and exhausted to the outside from the exhaust part 113a. Thereby, the material to be carbonized W1 in the drying chamber 113 can be dried by utilizing the flow of the high-temperature gas.

[0062] In addition, since it is provided with a first gate 121 for closing or opening the first lower opening 102b and a second gate 122 for closing or opening the second lower opening 101b, the fire extinguishing chamber 112 can be sealed. Thereby, the temperature environment and oxygen atmosphere in the fire extinguishing chamber 112 can be blocked from the outside, and the fire extinguishing function by the temperature reduction function and the reduction of the oxygen concentration can be exerted.

[0063] In addition, since it is provided with an inert gas supply device 150, for example, by supplying an inert gas to the fire extinguishing chamber 112 whose temperature environment and oxygen atmosphere are blocked from the outside, the oxygen concentration can be forcibly and quickly reduced.

[0064] In addition, since it is provided with a water spraying device 160, for example, by spraying water into the fire extinguishing chamber 112 whose temperature environment and oxygen atmosphere are blocked from the outside, the fire can be forcibly and quickly extinguished.

[0065] In addition, since the control unit 170 calculates the discharge amount of the carbide W2 from the conveyance speed of the carbide W2 by the first conveyor 131 and the opening area of the first lower opening 102b, for example, the input amount of the material to be carbonized W1 can be determined in consideration of the discharge amount. That is, the balance between the discharge amount of the carbide W2 and the input amount of the material to be carbonized W1 can be achieved.

[0066] Further, when the temperature of the fire extinguishing chamber 112 is equal to or lower than a predetermined temperature, the control unit 170 opens the second lower opening 101b by the second gate 122, so that the carbide W2 is extinguished, and when the temperature of the fire extinguishing chamber 112 (predetermined temperature) is reached at which it is estimated that the carbide W2 has been sufficiently cooled, the second lower opening 101b can be opened to prepare for discharging the carbide W2.

[0067] Further, since the control unit 170 determines the conveyance speed of at least any one of the first conveyor 131, the second conveyor 132, and the third conveyor 133 based on the temperature and / or the component of the gas in the carbonization furnace 111, the input amount of the material to be carbonized W1 and the discharge amount of the carbide W2 can be controlled based on the temperature and / or the component of the gas.

[0068] Further, the control unit 170 identifies the reaction time optimal for carbonizing the material to be carbonized W1 in the carbonization furnace 111 based on the component of the material to be carbonized W1 or the carbide W2 in the carbonization furnace 111, and determines the conveyance speed of at least any one of the first conveyor 131, the second conveyor 132, and the third conveyor 133 based on the identified reaction time. Therefore, based on the reaction time, the input amount of the material to be carbonized W1, the residence time of the material to be carbonized W1 in the carbonization furnace 111, and the discharge amount of the carbide W2 can be controlled.

[0069] Further, since the carbonization furnace 111 and the fire extinguishing chamber 112 are separated by a common partition wall 102, the furnace equipment 100 can be made compact.
