Description

[Technical field]

[0001] The present invention relates to a reaction apparatus and a reactor. [Background technology]

[0002] There are reactors for producing desired products by providing a specific atmosphere to powdered or granular materials to be treated. For example, a reactor generally called a rotary kiln heats a hollow reaction vessel that rotates around a central axis, and produces the desired product by passing the material through the reaction vessel while rolling it. Another reactor, for example, called a roller hearth kiln, produces the desired product by passing the material or workpiece through a tunnel-shaped reaction vessel. Various other reactors have also been developed.

[0003] For example, Patent Document 1 discloses the following reaction apparatus. The reaction apparatus has a screw feeder body that serves as a pressure reaction vessel, a catalyst supplying section that introduces a catalyst into the screw feeder body, and a lower hydrocarbon supplying section that introduces lower hydrocarbons into the screw feeder body. The reaction apparatus also has a screw that transports the generated nanocarbon, a solid delivery section that delivers the catalyst and nanocarbon transported by the screw, and a gas delivery section that delivers the generated hydrogen to the outside of the feeder body.

Mode for Carrying Out the Invention

[0010] Hereinafter, the present invention will be described through embodiments of the invention, but the invention according to the claims is not limited to the following embodiments. Also, not all of the configurations described in the embodiments are essential as means for solving the problems. For clarity of explanation, the following description and drawings have been appropriately omitted and simplified. In each drawing, the same elements are denoted by the same reference numerals, and duplicate explanations are omitted as necessary.

[0011] <Embodiment 1 (Reference Example)> While referring to Fig. 1, the main configuration of the reaction apparatus according to Embodiment 1 (Reference Example) will be described. Fig. 1 is a side view of the reaction apparatus 10 according to Embodiment 1. The reaction apparatus 10 shown in the figure is shown in a state where a part thereof is cut away for easy understanding.

[0012] The reaction apparatus 10 is an apparatus for producing a product by applying conditions such as a predetermined physical stimulus to a powder or granular material to be treated. The reaction apparatus 10 includes a cylindrical reaction vessel 100 (reactor), a supply section (supply port 101) for supplying the material to be treated R10 to the reaction vessel 100, an outlet section (outlet 102) for delivering the product from the reaction vessel 100, a transport mechanism 120 (e.g., a screw) for transporting the material to be treated R10 supplied to the reaction vessel 100 from the supply section of the reaction vessel 100 to the outlet section of the reaction vessel 100, a fluid supply section (first fluid inlet 131, first fluid outlet 132, first valve 134, etc.) for supplying a fluid that comes into contact with the transported material to the inside of the reaction vessel 100, and a temperature control section (a temperature sensor 136, a temperature sensor 138, a temperature sensor 139, a temperature sensor 140, a temperature sensor 141, a temperature sensor 142, a temperature sensor 143, a temperature sensor 144, a temperature sensor 145, a temperature sensor 146, a temperature sensor 147, a temperature sensor 148, a temperature sensor 149 ... 100 The device is provided with temperature control sections (temperature control area 110, etc.) that control different areas in different directions.

[0013] The physical stimulus is not particularly limited as long as it is a means used in the process of changing the processed material into the product. The physical stimulus is, for example, a temperature change such as heating or cooling. The physical stimulus is, for example, a stress transfer such as stirring, mixing, kneading, or pulverization. The physical stimulus is, for example, a reaction involving the transfer of electrons or radicals.

[0014] In the reaction device 10, the material to be treated R10 supplied to the reaction vessel 100 is heated while being transported to the outlet side of the reaction vessel 100 by the transport mechanism 120, and a predetermined fluid that comes into contact with the material to be treated R10 being transported is supplied into the reaction vessel 100, so that the material to be treated R10 (material to be treated) is continuously treated at a predetermined temperature. The material to be treated may be a solid, a fluid, or a mixture of both. In order to stir the material to be treated while transporting it, the reaction vessel 100 itself may be rotatable, or a transport mechanism 120 having a rotatable structure may be provided in the reaction vessel 100.

[0015] The type and state of the processed material or product are not particularly limited, and may be an inorganic material such as a metal oxide or metal sulfide containing lithium as one of its components, or an organic material such as a hydrocarbon or food. The processed material may be a solid such as a powder or granular material, or a fluid such as a liquid or gas.

[0016] The processed product may pass through an intermediate in the process of changing into the product. The form or state of the intermediate is not particularly limited. The intermediate may be, for example, a product in each reaction when two or more reactions are carried out stepwise. In that case, the intermediate is, for example, an anhydrous compound produced by heating a hydrated compound. Alternatively, the intermediate may be a monosaccharide produced by hydrolysis of a polysaccharide. The intermediate may be a fired body in which at least a part of the processed product has grown into grains or been sintered. The intermediate may be in a state in which at least a part of the processed product has been liquefied or vaporized. The intermediate may be in a state in which the temperature, hardness, etc. of the processed product have changed, although it does not appear to have changed. The intermediate may be in a form or state other than those described above.

[0017] The type and state of the product are not particularly limited, and the product may be a solid such as a powder or a fluid such as a liquid or gas. The product may be a mixture containing members other than the processed material, such as a catalyst or a transport auxiliary member. The product may be a mixture containing two or more compounds, such as a main product and a by-product.

[0018] The shape and size of the processed material or product are not particularly limited, but when the processed material or product is a powder or granular material, the particle size is preferably 50 mm or less, more preferably 0.005 to 20 mm. Furthermore, when the processed material or product is in the form of a lump, the ratio of the diagonal lengths (aspect ratio) is preferably 1 to 10, more preferably 1.3 to 1.8.

[0019] The reaction apparatus 10 mainly comprises a reaction vessel 100, a temperature control area 110, a transport mechanism 120, a first fluid control area 130, and a second fluid control area 140.

[0020] The reaction vessel 100 is, for example, cylindrical, and has a supply port 101 for receiving the material to be treated and a delivery port 102 for delivering the product. The supply port 101 is an example of a supply unit of the present disclosure. The shape and configuration of the reaction vessel 100 are not particularly limited. For example, the cross-sectional shape of the reaction vessel 100 may be circular or elliptical, or may be polygonal such as a square, or may be other shapes. For example, the reaction vessel 100 may be composed of one member, or may be composed of two or more members connected together. When two or more members are connected together, for example, a fastening means such as a bolt may be used at the point where the members are connected.

[0021] The reaction vessel 100 has an intermediate section A3 between the supply inlet 101 and the delivery outlet 102. The number and arrangement of the supply inlet 101, the delivery outlet 102, and the intermediate section A3 are not particularly limited. For example, two or more supply inlets 101 and delivery outlets 102 may be provided at each end of the intermediate section A3.

[0022] The supply port 101 may be located in the middle of the reaction vessel 100, and may have a middle section A3 and a delivery port 102 at both ends of the supply port 101. In this case, the material to be processed R10 may be supplied to the middle of the reaction vessel 100, and the product R11 may be delivered from one end side and the other end side of the reaction vessel 100, respectively. Furthermore, in this case, for example, a screw may be used as the conveying mechanism 120, and the direction of the helical convex part (spiral direction) on the screw may be reversed with the supply port 101 as the boundary, so that the material to be processed R10 may be branched and conveyed to one end side and the other end side of the reaction vessel 100, respectively, with the supply port 101 as the boundary. Alternatively, when the discharge port 102 is located in the middle of the reaction vessel 100 and the middle section A3 and the supply port 101 are provided at both ends of the discharge port 102, for example, a screw may be used as the conveying mechanism 120, and the direction of the helical convex part (spiral direction) on the screw may be reversed at the discharge port 102, for example, so that the product R11 is conveyed so as to be gathered from one end side and the other end side of the reaction vessel 100 at the discharge port 102. In this way, a means for conveying the material R10 to be processed, the product R11, etc. so as to diverge or gather in the conveying direction is desirable, for example, when a plurality of reaction devices 10 are connected in parallel.

[0023] The reaction vessel 100 is made of a material that can tolerate temperature changes occurring during the production of a product in the furnace, and contact with substances (such as materials to be processed) supplied to the furnace and substances (such as products) produced. The reaction vessel 100 and the transport mechanism 120 can be made of, for example, alloys, ceramics, carbon, and composite materials containing two or more of these. The alloys are metal members containing at least one of alloy elements such as nickel, cobalt, chromium, molybdenum, tungsten, tantalum, titanium, iron, copper, aluminum, silicon, boron, and carbon as components. The ceramics can include ceramic members such as oxides such as alumina and zirconia, carbides such as silicon carbide and titanium carbide, nitrides such as silicon nitride and titanium nitride, and borides such as chromium boride, as well as glass materials having at least a part of an amorphous structure. The carbon is a carbon member such as crystalline graphite and fiber-reinforced graphite.

[0024] The reaction apparatus 10 shown in FIG. 1 lies horizontally, has a supply port 101 at the upper left end of FIG. 1, and has an outlet port 102 at the lower right end. The reaction vessel 100 shown in FIG. 1 receives the material R10 to be treated from the supply port 101. The reaction vessel 10 conveys the material R10 received by the reaction vessel 100 from the supply port 101 (A1) of the reaction vessel 100 through the middle part A3 to the outlet port 102 (A2) of the reaction vessel 100 by a conveying mechanism 120 provided inside the reaction vessel 100. The reaction vessel 10 produces a product R11 from the material R10 to be treated by passing the material R10 through the middle part A3 of the reaction vessel 100. The reaction vessel 100 then outputs the produced product R11 from the outlet port 102.

[0025] The temperature control area 110 includes a temperature control device, i.e., a heating device or a cooling device, and controls the temperature of the reaction vessel at a predetermined position in the intermediate portion A3 between the supply port 101 and the delivery port 102. The temperature control area 110 and the like are an example of a temperature control portion of the present disclosure. The temperature control area 110 shown in FIG. 1 has a heating device surrounding the cylindrical reaction vessel 100 in the intermediate portion A3 of the reaction vessel 100. The heating device includes any heater capable of controlling temperature, such as a sheath heater, a coil heater, or a ceramic heater. The heating device performs heating in a range from room temperature to about 1000 degrees Celsius, for example. The temperature control area 110 may have a configuration in which the cylindrical reaction vessel 100 is divided and surrounded by a plurality of heating devices in the intermediate portion A3 of the reaction vessel 100. This allows different temperatures to be set individually in each of the upper, lower, left, and right portions around the reaction vessel 100, for example. In addition, the temperature of the intermediate portion A3 can be controlled for each different region in the short axis direction of the reaction vessel 100. The temperature control area 110 is arranged such that the axis AX of the transport mechanism 120 described later is fixed to each area of ​​the intermediate portion A3 of the reaction vessel 100. 120 For example, the temperature control region 110 can control the temperature change applied to the object to be treated R10 in the first fluid control region 130 and the second fluid control region 140 described below.

[0026] The temperature control area 110 may also include a control device for controlling a heating device or a cooling device. For example, the temperature control area 110 may have a thermometer for monitoring the temperature at a predetermined position of the reaction vessel 100. In addition, in the case where the heating device has a principle of heating by passing an electric current, the reaction vessel 100 may perform temperature control by monitoring the electric current value.

[0027] The temperature control area 110 may be configured to perform heating or cooling by circulating water or oil, for example. The temperature control area 110 may also be configured to perform cooling by using a Peltier element, for example. With the above-mentioned configuration, the temperature control area 110 is configured to perform heating or cooling by circulating water or oil, for example, by using a Peltier element, for example. 120 Various temperature distributions can be set along the directions.

[0028] As described above, the temperature control area 110 controls the temperature of the reaction vessel 100 (for example, the middle part A3) along the long axis AX 100 It is possible to control each of the different regions in the direction.

[0029] The conveying mechanism 120 conveys the material R10 supplied from the supply port 101 toward the discharge port 102 by extending, for example, from one end side A1 to the other end side A2 of the reaction vessel 100. The shape and conveying method of the conveying mechanism 120 of the present disclosure are not limited as long as it can convey raw materials, products, etc. The conveying mechanism 120 may be a screw provided inside the reaction vessel 100 so as to extend from one end side to the other end side of the reaction vessel 100. The conveying mechanism 120 may be a drum provided inside the reaction vessel 100 so as to extend from one end side to the other end side of the reaction vessel 100. The conveying mechanism 120 may be a belt conveyor provided inside the reaction vessel 100 so as to extend from one end side to the other end side of the reaction vessel 100. The conveying mechanism 120 may be a blower provided inside the reaction vessel 100. The conveying mechanism 120 may be a vibration generating device provided inside the reaction vessel 100. The transport mechanism 120 may be other than the above.

[0030] The size of the transport mechanism 120 is not particularly limited, and may be shorter than the overall length of the reaction vessel 100, for example. The material forming the transport mechanism 120 is not particularly limited, but it is desirable that the transport mechanism 120 is formed from a material that can tolerate temperature changes occurring during the production of a product, and contact with substances (such as processed materials) supplied into the vessel and substances (such as products) produced, similar to the reaction vessel 100. The transport mechanism may be formed from, for example, alloys, ceramics, carbon, and composite materials containing two or more of these materials.

[0031] 1 is an example of a screw mechanism, and a spiral convex portion 121 is formed around a main axis extending in the longitudinal direction of the reaction vessel 100. The convex portion 121 rotates while in contact with the material to be treated R10, whereby the conveying mechanism 120 conveys the material to be treated R10 from the supply port side to the delivery port side.

[0032] The shape of the convex portion 121 shown in FIG. 1 is an example, and the shape of the convex portion 121 is not limited to this. The convex portion 121 may have a different shape for each region of the reaction vessel 100. More specifically, for example, the pitch of the spiral of the convex portion 121 may change. The spiral shape of the convex portion 121 may be two-stranded instead of one-stranded. The convex portion 121 may have a portion that is not a spiral shape. The convex portion 121 may be provided in a direction in which the apex of the convex portion forms an angle of 90 degrees with respect to the long axis direction of the screw. Furthermore, the convex portion 121 may extend in a direction in which the angle forms an angle of 0 degrees with respect to the long axis direction of the screw. This allows the reaction device 10 to set the moving speed and behavior of the object present inside the reaction vessel 100 for each region. More specifically, for example, the reaction device 10 transports, stirs, mixes, retains, kneads, or crushes the object in the reaction vessel 100.

[0033] The transport mechanism 120 is supported by a shaft at both ends (one end side A1, the other end side A2) of the reaction vessel 100. The transport mechanism 120 illustrated in FIG. 1 is a screw, and is connected (coupled) to a drive device 150 at one end side B1. The drive device 150 is an example of a drive device for the transport mechanism 120 in the present disclosure. The drive device 150 includes a motor 151 provided on one end side of the reaction vessel 10, and a reducer 152 provided between the motor 151 and one end side A1 of the reaction vessel 100. The reducer 152 includes an input shaft coupled to the rotating shaft of the motor 151 and an output shaft coupled to one end side B1 of the transport mechanism 120, and reduces the rotation of the rotating shaft of the motor 151 and transmits it to the transport mechanism 120 to rotate the transport mechanism 120. The drive device 150 may be set to be capable of changing the rotation speed of the transport mechanism 120. In this case, the driving device 150 may be a motor with a variable rotation speed, or may be a combination of a motor with a fixed rotation speed and a reducer with a variable reduction ratio.

[0034] The first fluid control region 130 includes a first fluid inlet 131 and a first fluid outlet 132 for passing the first fluid through the reaction vessel 100 in a predetermined region in the intermediate section A3. The first fluid control region 130 is provided between the supply port 101 and the second fluid control region 140 in the reaction vessel 100. The first fluid inlet 131 is connected to a first fluid supply pipe 133, and supplies the first fluid supplied from the first fluid supply pipe 133 to the reaction vessel 100. The first fluid supply pipe 133 includes a first valve 134 for adjusting the flow rate of the first fluid. The first fluid supply pipe 133 may also supply the first fluid to the reaction vessel 100 intermittently while controlling the time by opening and closing the first valve 134. The first fluid outlet 132 connected to the first fluid discharge pipe 135 is a hole for discharging the fluid in the first fluid control region 130 to the outside of the reaction vessel 100. The first fluid discharge pipe 135 may be provided with a valve or discharge mechanism for adjusting the flow rate or flow speed of the fluid discharged from the reaction vessel 100. The discharge mechanism is, for example, a suction mechanism such as a pump or an ejector using the Venturi effect. A plurality of first fluid inlets 131 and first fluid outlets 132 may be provided. In the first fluid control region 130, the locations where the first fluid inlets 131 and first fluid outlets 132 are provided are not particularly limited, and they may be provided at the top, bottom, or side of the reaction vessel 100. In addition, the first fluid inlet 131 may be provided at the bottom of the reaction vessel 100 and the first fluid outlet 132 may be provided at the top of the reaction vessel 100 to generate an airflow in a predetermined direction in the reaction vessel. In this way, the first fluid is easily brought into contact with the treatment object, and the reaction of the treatment object can be suitably carried out. Moreover, by making the inner diameter of the first fluid inlet 131 smaller than the inner diameter of the first fluid supply pipe 133, the first fluid may be vaporized when it is supplied to the reaction vessel 100. In this way, the temperature of the atmosphere around the object to be treated can be adjusted by the heat of vaporization, and the reaction of the object to be treated can be suitably controlled.

[0035] With the above-mentioned configuration, the reaction device 10 makes the treatment product R10 into an intermediate by contacting the treatment product R10 with the first fluid in the first fluid control region 130. The reaction device 10 also discharges the fluid after contacting the treatment product R10 to the outside of the first fluid control region 130. The reaction device 10 can promote the reaction by the first fluid by transporting the treatment product R10 or the intermediate product while the transport mechanism 120 rotates and further contacting the first fluid. The form and composition of the first fluid are not limited as long as it has fluidity. The first fluid may be a gas or a liquid. The first fluid may be a dispersion liquid in which a solid is dispersed in a liquid. The temperature of the reaction vessel 100 and the transport mechanism 120 can be partially controlled by supplying the first fluid to the reaction device 10. Therefore, the reaction device 10 can efficiently control the temperature of the treatment product R10 and efficiently turn the treatment product R10 into an intermediate product. Before the first fluid is supplied to the reaction vessel 100, a mechanism for adjusting the temperature and pressure of the first fluid may be provided.

[0036] The second fluid control region 140 includes a second fluid inlet 141 and a second fluid outlet 142 for passing a second fluid in a region in the intermediate portion A3 different from the first fluid control region 130. That is, the second fluid control region 140 can have a configuration equivalent to that of the first fluid control region 130 in a region different from the first fluid control region 130.

[0037] The second fluid control region 140 is provided between the first fluid control region 130 and the delivery port 102 in the reaction vessel 100. The second fluid inlet 141 is connected to a second fluid supply pipe 143, and supplies the second fluid supplied from the second fluid supply pipe 143 to the reaction vessel 100. The second fluid supply pipe 143 includes a second valve 144 for adjusting the flow rate of the second fluid. The second fluid supply pipe 143 may supply the second fluid while controlling the time timing of supplying the second fluid to the reaction vessel 100 to be an intermittent interval by opening and closing the second valve 144. The second fluid outlet 142 connected to the second fluid discharge pipe 145 is a hole for discharging the fluid in the second fluid control region 140 to the outside of the reaction vessel 100. The second fluid discharge pipe 145 may include a valve or discharge mechanism for adjusting the flow rate or flow speed of the fluid discharged from the reaction vessel 100. The discharge mechanism is, for example, a suction mechanism such as a pump or an ejector. The first fluid inlet 131, the first fluid outlet 132, and the first valve 134 are an example of a fluid supply unit of the present disclosure.

[0038] With the above-mentioned configuration, the reaction device 10 contacts the intermediate after passing through the first fluid control region 130 with the second fluid in the second fluid control region 140 to generate the product R11. The reaction device 10 also discharges the fluid after contacting the intermediate to the outside of the second fluid control region 140. The form and composition of the second fluid are not limited as long as it has fluidity. The second fluid may be a gas or a liquid. The second fluid may be a dispersion liquid in which a solid is dispersed in a liquid. In addition, by supplying the second fluid to the reaction device 10, the temperature of the reaction vessel 100 and the transport mechanism 120 can be partially controlled. Therefore, the reaction device 10 can efficiently control the temperature of the intermediate, and can efficiently convert the intermediate into the product R11.

[0039] Although the configuration of the reaction device 10 has been described above, the reaction device 10 according to the first embodiment is not limited to the above configuration. For example, the number of the transport mechanisms 120 may be one or more, or may be two or more. That is, the reaction device 10 may have a plurality of transport mechanisms 120 arranged in parallel.

[0040] The cross-sectional shape of the reaction vessel 100 in a plane perpendicular to the axis of the transport mechanism 120 may have a combination defined by a Reuleaux constant width figure. In this case, the transport mechanism 120 is preferably a screw, and the cross-sectional shape of the convex portion 121 of the screw has a shape combining multiple arcs corresponding to the Reuleaux constant width figure. For example, when the cross-sectional shape inside the reaction vessel 100 is circular, the cross-sectional shape of the screw may have a Reuleaux constant width figure composed of three arcs.

[0041] The reaction vessel 100 is not limited to one lying parallel to the horizontal direction, but may have a predetermined angle with respect to the horizontal plane, and the reaction vessel 100 may have an inclined surface. The reaction device 10 has the first fluid control region 130 and the second fluid control region 140 in the intermediate section A3, but may also have a configuration for passing another fluid. That is, the reaction device 10 may have three or more fluid control regions. Alternatively, the reaction device 10 may have only the first fluid control region 130 in the intermediate section A3. The reaction device 10 is controlled by a control device described later.

[0042] Next, the function of the reaction device 10 will be described with reference to Fig. 2. Fig. 2 is a block diagram of the reaction device 10 according to the first embodiment. In addition to the configuration shown in Fig. 1, the reaction device 10 has a control device 200, a temperature control device 210, a first fluid control device 230, a second fluid control device 240, and an information input / output device 250 (information input / output unit 250).

[0043] The control device 200 is a circuit board including a calculation device such as a CPU (Central Processing Unit) and an MCU (Micro Controller Unit). The control device 200 is communicatively connected to each of the temperature control device 210, the first fluid control device 230, the second fluid control device 240, and the information input / output unit 250, and controls the configuration of each of these. The control device 200 realizes its functions by hardware and software implemented on the circuit board.

[0044] The control device 200 has, as its main functional components, an overall control unit 201, a temperature control unit 202, a transport control unit 203, a first fluid control unit 204, a second fluid control unit 205, an IF control unit 206, and a memory unit 207. These functional components of the control device 200 may be integrated or may be discrete. Furthermore, these functional components of the control device 200 may be realized by interlocking a plurality of separate devices.

[0045] The overall control unit 201 is connected to each functional configuration of the control device 200 and controls the overall operation of these functions. For example, the overall control unit 201 can perform an operation such as issuing an operation instruction to the transport control unit 203 depending on the state of the temperature supplied from the temperature control unit 202.

[0046] The temperature control section 202 is connected to the temperature control device 210 and controls the temperature of the reaction vessel 100 in the temperature control area 110. The temperature control section 202 has at least one of a heating device and a cooling device. The temperature control section 202 may also have one or more thermometers for controlling the temperature.

[0047] The transport control unit 203 is connected to the driving device 150 and controls the operation of the driving device 150. The transport control unit 203 may have, for example, a motor driving circuit for driving a motor (motor 151) included in the driving device 150. The transport control unit 203 may also have a rotation sensor for monitoring the number of rotations of the motor (motor 151).

[0048] The first fluid control section 204 controls the flow of the first fluid in the first fluid control region 130. More specifically, the first fluid control section 204 is connected to the first fluid control device 230 and controls the operation of the first fluid control device 230. The first fluid control device 230 includes a first valve 134 for pumping the first fluid. The second fluid control section 205 controls the flow of the second fluid in the second fluid control region 140. More specifically, the second fluid control section 205 is connected to the second fluid control device 240 and controls the operation of the second fluid control device 240. The second fluid control device 240 includes a second valve 144 for pumping the second fluid.

[0049] The IF control unit 206 (IF = Interface) is an interface that is connected to the information input / output unit 250 and exchanges information with the user via the information input / output unit 250. That is, the IF control unit 206 accepts operations from the user via the information input / output unit 250 and appropriately supplies information related to the accepted operations to each component of the control device 200. The IF control unit 206 also controls the state of a display unit that the information input / output unit 250 has.

[0050] The storage unit 207 is a storage device including a non-volatile memory such as a flash memory or an SSD (Solid State Drive). The storage unit 207 stores a program for the reaction device 10 to realize the functions of the present disclosure. The storage unit 207 also includes a volatile memory, and temporarily stores predetermined information when the control device 200 operates. The information input / output unit 250 has, for example, a button, a switch, or a touch panel for accepting an operation from a user. The information input / output unit 250 also includes a display device for presenting information to a user.

[0051] The above describes the functional blocks of the reaction apparatus 10. With the above-mentioned configuration, the reaction apparatus 10 transports the received treatment object R10 using the transport mechanism 120, controls the temperature of the reaction vessel 100, and controls the atmosphere in the first fluid control region 130 and the second fluid control region 140.

[0052] Next, a method for producing the product R11 (product production method) executed by the reaction device 10 will be described with reference to Fig. 3. Fig. 3 is a flowchart of the process executed by the reaction device 10. The flowchart shown in Fig. 3 starts, for example, by starting the supply of the product R10 to be treated to the reaction device 10.

[0053] First, the reaction device 10 receives a predetermined material to be treated R10 from the supply port 101 (step S11).

[0054] Next, the control device 200 of the reaction device 10 controls the temperature by driving the heating device or the cooling device of the temperature control region 110 of the reaction vessel 100 via the temperature control section 202 (step S12).

[0055] Next, the control device 200 of the reaction device 10 drives the driving device 150 via the transport control unit 203. As a result, the driving device 150 drives the transport mechanism 120. Then, the transport mechanism 120 transports the received object to be processed R10 toward the outlet 102 (step S13).

[0056] Next, the control device 200 of the reaction device 10 controls the flow of the first fluid passed through the first fluid control region 130 (first atmosphere control region) via the first fluid control unit 204 (step S14).

[0057] Next, the control device 200 of the reaction device 10 controls the flow of the second fluid passed through the second fluid control region 140 (second atmosphere control region) via the second fluid control section 205 (step S15).

[0058] Next, the reaction device 10 discharges the product R11 that has passed through the second fluid control region 140 from the discharge port 102 (step S16).

[0059] The above describes the reaction method (product production method) executed by the reaction apparatus 10. The above-mentioned method is shown along the flow from when the reaction apparatus 10 produces the product R11 from the treated material R10 to when the produced product R11 is discharged. However, the reaction apparatus 10 may perform the temperature control in step S12, for example, before step S11. Also, for example, the reaction apparatus 10 may start step S14 and step S15 simultaneously.

[0060] The first embodiment (reference example) has been described above. In the above-mentioned reaction device 10, the reaction device 10 has two fluid control regions (the first fluid control region 130 and the second fluid control region 140), but the reaction device 10 may have one or three or more fluid control regions. In addition, the reaction device 10 has an axis AX 120 The reactor 10 may have a plurality of temperature control regions 110 along the direction (longitudinal direction). The above-mentioned reactor 10 brings a plurality of fluids into contact with the object to be treated R10 received from the supply port 101 in the intermediate section A3. In addition, the reactor 10 has a plurality of fluids in contact with the object to be treated R10 in the intermediate section A3 along the axis AX of the transport mechanism 120. 120 The temperature of the reaction vessel 100 is controlled along the longitudinal direction (longitudinal direction). Furthermore, the reaction device 10 can transport an object inside the reaction vessel 100 and provide a physical stimulus to it. The reaction device 10 can simultaneously and accurately perform the above-mentioned atmosphere control, temperature control, and physical control. Therefore, according to the first embodiment, a reaction device or the like that efficiently manufactures a desired product can be provided.

[0061] <Embodiment 2> Next, as the second embodiment, a configuration example for supporting the reaction vessel 100 and a configuration example for supporting the transport mechanism 120 will be described with reference to FIG. 4. This configuration example can be applied to the above-mentioned first embodiment (reference example). FIG. 4 is a side view of a reaction apparatus according to the second embodiment. FIG. 4 corresponds to FIG. 1 to which a first support section 103 and a second support section 104 have been added. Other than that, the configuration is the same as that of FIG. 1. The following description will focus on the differences from the first embodiment (reference example).

[0062] <Example of a configuration for supporting the reaction vessel 100> As shown in Fig. 4, the reaction apparatus 10 includes a first support part 103 and a second support part 104 as a structure for supporting the reaction vessel 100. The reaction vessel 100 in Fig. 4 is a cylindrical reaction vessel (furnace) including an intermediate part A3 between one end side A1 and the other end side A2, and is supported by the first support part 103 and the second support part 104 installed on a floor surface 170. The floor surface 170 may be the floor surface of a building in which the reaction apparatus 10 is installed, or may be a surface of a part of a structure constituting the reaction apparatus 10, such as the upper surface of a stand.

[0063] The first support portion 103 is disposed on a floor surface 170 below one end side A1 of the reaction vessel 100, and supports one end side A1 of the reaction vessel 100 from below. Specifically, the first support portion 103 supports one end side A1 of the reaction vessel 100 from the bottom side. 100 The reaction vessel 100 is supported in a state where it cannot move in the direction. This is realized, for example, by fixing one end side A1 of the reaction vessel 100 supported by the first support part 103 to the first support part 103 by a direct fixing means such as a bolt or welding. Alternatively, without being limited to a direct fixing means, for example, the reaction vessel 100 may be indirectly fixed by contacting one end side A1 of the reaction vessel 100 supported by the first support part 103 with a member such as a plate material or wire material separately fixed to a stand or the like.

[0064] On the other hand, the second support part 104 is disposed on a floor surface 170 below the other end side A2 of the reaction vessel 100, and supports the other end side A2 of the reaction vessel 100 from below. 100 This is realized, for example, by specific examples 1 to 3 described later.

[0065] The other end A2 of the reaction vessel 100 is aligned along the long axis AX 100 The technical significance of supporting the device in a state in which it can move in the direction is as follows.

[0066] That is, when the temperature of the reaction vessel 100 is controlled by the temperature control device 210 or the like (for example, when it is heated from room temperature to about 900 degrees) as described in the above embodiment 1 (reference example), the reaction vessel 100 moves in a direction parallel to its long axis AX 100 thermal expansion along the major axis AX 100 In this case, if the other end A2 of the reaction vessel 100 is parallel to the longitudinal axis AX 100 When the reaction vessel 100 is immobilized in the long axis AX 100 Thermal expansion in the direction of the axis ...

[0067] Therefore, the reaction vessel 100 has a long axis AX 100 In order to prevent the driving device 150 from being damaged due to thermal expansion in the direction of the axis of the reaction vessel 100, the second support portion 104 supports the other end A2 of the reaction vessel 100 in the direction of the long axis AX of the reaction vessel 100. 100 The support is supported in a state in which it can move in the direction.

[0068] Next, the other end A2 of the reaction vessel 100 is aligned along the long axis AX 100 A specific example of supporting the object in a state where the object can move in the direction will be described.

[0069] <Example 1> FIG. 5(a) shows the other end A2 of the reaction vessel 100 along the long axis AX 100 5(a) is a view seen from the direction of arrow AR1 in FIG.

[0070] As shown in FIG. 5(a), in the first specific example, the other end A2 of the reaction vessel 100 is aligned along the long axis AX 100In order to make the reaction vessel 100 movable in the axial direction, a flange portion 109 is provided on the other end side A2 of the reaction vessel 100, a recess 109a is formed in the lower part of the flange portion 109, and a protrusion 104a that is inserted into the recess 109a is provided on the upper part of the second support portion 104, and the other end side A2 of the reaction vessel 100 is supported with the protrusion 104a inserted into the recess 109a. 100 The recess 109a extends in the direction of the groove 106. A gap G1 is formed between the lower surface 109b of the flange portion 109 and the upper surface 104b of the second support portion 104. A lubricant or the like may be supplied between the recess 109a and the protrusion 104a. Conversely, the protrusion 104a may be provided on the lower part of the flange portion 109, and the recess 109a into which the protrusion 104a is inserted may be formed on the upper part of the second support portion 104.

[0071] <Example 2> FIG. 5(b) shows the other end A2 of the reaction vessel 100 along the long axis AX 100 5(b) is a view seen from the direction of arrow AR1 in FIG.

[0072] As shown in FIG. 5(b), in the second example, the other end A2 of the reaction vessel 100 is aligned along the long axis AX 100In this example, in order to allow the reaction vessel 100 to move in the direction, a flange portion 109 is provided on the other end side A2 of the reaction vessel 100, a friction reduction member 111 is provided on the upper surface 104b of the second support portion 104, and the other end side A2 of the reaction vessel 100 is supported with the lower surface 109b of the flange portion 109 in contact with the friction reduction member 111. The form, shape, and material of the friction reduction member 111 are not particularly limited as long as it is a member that smoothly moves the reaction vessel 100. The friction reduction member 111 may be a member having a rotating part such as a roller or a belt. The friction reduction member 111 may be a member made of a high hardness material having a Vickers hardness (HV) of 450 or more or a Rockwell hardness (HRC) of 45 or more on the surface where the friction reduction member 111 supports the reaction vessel 100, such as a tool steel material that can be subjected to a quenching heat treatment, a nitriding steel material that can be subjected to a nitriding heat treatment, a powder metallurgy material that contains ceramic particles at least in a part, or a steel material with a coating applied to the surface. The friction reducing member 111 may be a member whose surface is coated with, for example, diamond-like carbon (DLC), titanium carbide (TiC), titanium carbonitride (TiBN), titanium boride (TiB2), vanadium carbide (VC), alumina (Al2O3), zirconia (ZrO2), or the like by a film forming means such as CVD, PVD, or thermal spraying. The friction reducing member 111 may be a member whose surface is coated with chrome plating or nickel plating (Ni-P or Ni-Co-W) by electroplating or electroless plating. The friction reducing member 111 may be a member whose surface is coated with a compound having solid lubricity such as molybdenum disulfide by a coating means such as a spray. In other words, the chemical composition of the surface (support surface) on which the friction reducing member 111 supports the reaction vessel 100 preferably contains at least one of the elements (chemical elements) of B, C, N, Al, P, Ti, V, Cr, Co, Ni, Mo, and W.

[0073] <Example 3> FIG. 5(c) shows the other end A2 of the reaction vessel 100, which is aligned along the long axis AX 100 5(c) is a view seen from the direction of arrow AR1 in FIG.

[0074] As shown in FIG. 5(c), in the third embodiment, the other end A2 of the reaction vessel 100 is aligned along the long axis AX 100 In order to make the reaction vessel 100 movable in the axial direction, a flange portion 109 having protruding portions 109c and 109d protruding on both the left and right sides (protruding in a direction intersecting (for example, perpendicular to) the long axis of the reaction vessel 100) is provided on the other end side A2 of the reaction vessel 100, and standing portions 104c and 104d are provided on the upper surface 104b of the second support portion 104, and the other end side A2 of the reaction vessel 100 is supported in a state in which the protruding portions 109c and 109d are placed on the standing portions 104c and 104d. A gap G2 is formed between the lower surface 109b of the flange portion 109 and the upper surface 104b of the second support portion 104, and gaps G3 and G4 are formed between the left and right sides of the flange portion 109 and the standing portions 104c and 104d. Lubricating oil or the like may be supplied between the protruding portions 109c and 109d and the standing portions 104c and 104d.

[0075] As in the above specific examples 1 to 3, the other end A2 of the reaction vessel 100 is aligned along the long axis AX 100 The reaction vessel 100 is supported in a movable state along its long axis AX. 100 This can prevent the drive device 150 from being damaged or the like due to a force acting on the drive device 150 caused by thermal expansion (or thermal contraction) in the direction.

[0076] <Example of configuration for supporting the transport mechanism 120> As shown in FIG. 4, the reaction apparatus 10 includes bearings 106 and 107 as a structure for supporting the screw serving as the transport mechanism 120.

[0077] The bearing 106 is provided at one end side A1 of the reaction vessel 100, and rotatably supports one end side B1 of the transport mechanism 120. The bearing 106 is, for example, a bearing or a bush. The one end side B1 of the transport mechanism 120 is connected (fixed) to the output shaft of the reducer 152. That is, the one end side B1 of the transport mechanism 120 is rotatable and is connected to the axis AX of the transport mechanism 120. 120 The actuator is supported in such a way that it cannot move in any direction.

[0078] On the other hand, the bearing 107 is provided on the other end side A2 of the reaction vessel 100, and is capable of rotating the other end side B2 of the transport mechanism 120 and is connected to the axis AX 120 The bearing 107 is an example of a third support portion and a sixth support portion of the present disclosure. The bearing 107 is, for example, a bearing or a bush. The other end B2 of the transport mechanism 120 is supported by the axis AX of the transport mechanism 120. 120 In order to allow the transport mechanism 120 to move in the direction of the axis AX of the transport mechanism 120, a predetermined range (see the range indicated by the symbol L1 in FIG. 4) of the other end side B2 of the transport mechanism 120 is not provided with a spiral convex portion 121. In addition, between the end of the other end side B2 of the transport mechanism 120 and the lid portion 108 provided on the other end side A2 of the reaction vessel 100, 120 4) into which the other end B2 of the transport mechanism 120 moving in the forward direction (right side in FIG. 4) enters (see the range indicated by the symbol L2 in FIG. 4).

[0079] The axis AX of the transfer mechanism 120 supported as described above 120 and the long axis AX of the reaction vessel 100 100 are consistent (almost consistent).

[0080] The other end B2 of the transport mechanism 120 is connected to the axis AX 120 The technical significance of supporting the device in a state in which it can move in the direction is as follows.

[0081] That is, when the temperature of the reaction vessel 100 is controlled by the temperature control device 210 or the like (for example, when it is heated from room temperature to about 900 degrees Celsius) as described in the above embodiment 1 (reference example), the reaction vessel 100 rotates along its long axis AX 100 thermal expansion along the major axis AX 100 (The transfer mechanism 120 also thermally expands in the direction of its axis AX.) 120 Thermal expansion in the direction (for example, axis AX 120 In this case, if the other end B2 of the transport mechanism 120 is aligned along the axis AX 120 When the transport mechanism 120 is unable to move in the axis AX 120The transport mechanism 120 may be deformed due to thermal expansion in the direction, and the spiral convex portion 121 of the deformed transport mechanism 120 may come into contact with the inner wall of the reaction vessel 100, which may cause the transport mechanism 120 to become unable to rotate normally.

[0082] In addition, one end side B1 of the transport mechanism 120 is connected to the axis AX 120 The other end B2 of the transport mechanism 120 is set to a state in which it can move in the direction of the axis AX 120 If the reaction vessel 100 is unable to move in the direction, the other end side B2 of the conveying mechanism 120 will move due to thermal expansion and contraction of the reaction vessel 100, making it difficult to control the positions of the convex and concave portions of the screw, which may result in the material to be treated not being able to react normally.

[0083] Therefore, the transport mechanism 120 is connected to the axis AX 120 In order to prevent the conveying mechanism 120 from being deformed due to thermal expansion in the direction, the bearing 107 supports the other end B2 of the conveying mechanism 120 so as to be rotatable and to be supported by the axis AX 120 The support is supported in a state in which it can move in the direction.

[0084] As described above, the other end side B2 of the transport mechanism 120 is rotatable, and the axis AX 120 The transport mechanism 120 is supported in a state in which it can move in the axis AX 120 Therefore, deformation of the transport mechanism 120 due to thermal expansion in the direction can be prevented.

[0085] As described above, according to the second embodiment, the reaction vessel 100 is arranged along its major axis AX 100 It is possible to provide a reaction device 10 capable of preventing a malfunction caused by thermal expansion in the vertical direction.

[0086] Next, a modified example will be described.

[0087] In the above-mentioned second embodiment, an example has been described in which the reaction vessel 100 is supported so as not to be rotatable, but the present invention is not limited to this. For example, a reaction vessel 100 supported so as to be rotatable may be used.

[0088] FIG. 6 shows an example of a configuration for supporting the reaction vessel 100 so that it can rotate.

[0089] As shown in FIG. 6, the reaction apparatus 10 of this modified example includes bearings 112 and 113 as a structure for supporting the reaction vessel 100 so that the reaction vessel 100 is rotatable.

[0090] The bearing 112 is provided between the one end side A1 of the reaction vessel 100 and the first support portion 103, and is capable of rotating the one end side A1 of the reaction vessel 100 and is aligned with the long axis AX of the reaction vessel 100. 100 The reaction vessel 100 is supported in a state where it cannot move in the longitudinal direction. The bearing 112 is, for example, a bearing or a bush. A flange portion 114 is provided on one end side A1 of the reaction vessel 100. When this flange portion 114 comes into contact with the bearing 112, the one end side A1 of the reaction vessel 100 is supported in a state where it cannot move in the longitudinal direction. 100 6. A plurality of flanges 114 and bearings 112 may be provided. For example, two bearings 112 are used for one flange 114, and the flange 114 is sandwiched between the bearings 112, so that one end side A1 of the reaction vessel 100 is prevented from moving in the long axis AX of the reaction vessel 100. 100 The bearing 112 may be an annular bearing or bushing into which the one end side A1 of the reaction vessel 100 is inserted, or may be an arc-shaped bearing or bushing with a portion of the annular bearing or bushing cut out. Instead of the bearing 112, a member made of a lubricating material may be used to rotate the one end side A1 of the reaction vessel 100 and move in the longitudinal direction of the long axis AX of the reaction vessel 100. 100 The bearing 112 and the flange portion 114 are an example of a fourth support portion of the present disclosure.

[0091] On the other hand, the bearing 113 is provided between the other end side A2 of the reaction vessel 100 and the second support part 104, and is capable of rotating the other end side A2 of the reaction vessel 100 and supporting the long axis AX of the reaction vessel 100. 100The bearing 113 is, for example, a bearing or a bushing. The bearing 113 may be an annular bearing or bushing into which the other end side A2 of the reaction vessel 100 is inserted, or may be an arc-shaped bearing or bushing with a portion of the annular bearing or bushing cut out. Instead of the bearing 113, a member made of a lubricating material may be used to rotate the other end side A2 of the reaction vessel 100 and move along the long axis AX of the reaction vessel 100. 100 The reaction vessel 100 may be supported in a state in which it can move in the direction. The bearing 113 is an example of a fifth support portion of the present disclosure. The reaction vessel 100 supported rotatably in this modification is connected (coupled) at one end side A1 to a reaction vessel driving device 116 (not shown in FIG. 6) similar to the driving device 150 (screw driving device).

[0092] When using a configuration in which the reaction vessel 100 is rotatably supported as in this modified example, a rotatably supported transport mechanism 120 (see FIG. 4) may be used, or a non-rotatably supported transport mechanism 120 (not shown) may be used instead of the rotatably supported transport mechanism 120. Also, the transport mechanism 120 may be omitted.

[0093] In the above-mentioned second embodiment, the first support portion 103 that supports the one end side A1 of the reaction vessel 100 from below is used as the first support portion, but the present invention is not limited to this. 100 Any configuration may be used as the first support as long as it supports the reaction vessel 100 in a state where it cannot move in the direction. For example, although not shown, the first support may be a first support that supports one end side A1 of the reaction vessel 100 in a manner of suspending it from above, or a first support that supports one end side A1 of the reaction vessel 100 from the side.

[0094] In the above-mentioned second embodiment, an example was described in which the second support portion 104 is a support portion that supports the other end side A2 of the reaction vessel 100 from below, but this is not limited thereto. 100Any configuration of the support part may be used as long as it supports the reaction vessel 100 in a state where it can move in the direction. For example, although not shown, the second support part may be a second support part that supports the other end side A2 of the reaction vessel 100 in a manner of suspending it from above, or a second support part that supports the other end side A2 of the reaction vessel 100 from the side.

[0095] In the above embodiment, as shown in FIG. 5(a) and FIG. 7, the second support portion 104 supports the other end side A2 of the reaction vessel 100 along the long axis AX of the reaction vessel 100. 100 7 is a view seen from the direction of the arrow AR2 in FIG. 5(a). For example, the other end A2 of the reaction vessel 100 is supported in a state where it can move only in the long axis AX of the reaction vessel 100. 100 In addition to the direction, the rotation axis AX V It may be supported in a rotatable state around a vertical axis.

[0096] Next, the other end A2 of the reaction vessel 100 is aligned along the long axis AX 100 In addition to the direction, the rotation axis AX V A fourth concrete example will be described, in which the object is supported in a rotatable state around a (vertical axis).

[0097] <Example 4> FIG. 8 shows the other end A2 of the reaction vessel 100 along the long axis AX 100 In addition to the direction, the rotation axis AX V FIG. 11 is a schematic diagram of a fourth specific example in which the actuator is supported in a rotatable state around a vertical axis.

[0098] As shown in FIG. 8, the protrusion 104a is connected to the rotation axis AX via a bearing or the like. V The rotation axis AX is a vertical axis. V 8. In this way, the other end A2 of the reaction vessel 100 is aligned along the long axis AX 100 In addition to the direction, the rotation axis AX V It is supported in a rotatable manner around a vertical axis.

[0099] In this way, the other end A2 of the reaction vessel 100 is aligned along the long axis AX 100 In addition to the direction, the rotation axis AX V The advantages of supporting the device in a rotatable state around a vertical axis are as follows:

[0100] That is, depending on the state of the reaction (state of the physical stimulus), the longitudinal axis AX of the reaction vessel 100 in FIG. 100 In this case, a temperature difference may occur between the left and right sides of the reaction vessel 100. 100 A phenomenon occurs in which the amount of stretching differs between the left and right sides.

[0101] For example, in FIG. 7, the long axis AX 100 When the temperature on the right side is higher and the temperature on the left side is lower, the longitudinal axis AX 100 The right side stretches more and the left side stretches less. The lengths of the arrows AR3 and AR4 in Figure 7 represent this.

[0102] As described above, the long axis AX of the reaction vessel 100 100 If the left and right sides are stretched by different amounts, horizontal stress (see arrow AR5 in FIG. 7) may be generated on the other end side A2 of the reaction vessel 100.

[0103] When this stress occurs, friction occurs between the second support portion 104 (the convex portion 104a) and the flange portion 109 (the concave portion 109a), causing the reaction vessel 100 (the other end side A2) to rotate around the long axis AX 100 There is a risk of directional movement being impeded.

[0104] Therefore, by adopting the configuration shown in FIG. 8, it becomes possible to appropriately respond to various physical stimulus situations.

[0105] In particular, when the state where a temperature difference is intentionally created between the left and right sides of the reaction vessel 100 is applied to a twin-screw type reaction vessel 100A (see FIG. 9), it is effective for controlling the reaction rate of the material to be treated. FIG. 9 shows an example of a twin-screw type reaction vessel 100A.

[0106] Next, the other end A2 of the reaction vessel 100 is aligned along the long axis AX 100 A fifth concrete example will be described in which the support is movable in the minor axis direction (see arrow AR6 in FIG. 10) in addition to the minor axis direction.

[0107] <Example 5> FIG. 10 shows the other end A2 of the reaction vessel 100 along the long axis AX 100 10 is a schematic diagram of a fifth embodiment in which the support is movable in the short axis direction (see arrow AR6 in FIG. 10) in addition to the short axis direction.

[0108] As shown in FIG. 10, the protrusion 104a is connected to the rotation axis AX via a bearing or the like. V The base 104e is supported on the second support portion 104 (upper surface 104b) so as to be rotatable around the rotation axis AX (vertical axis). The base 104e is further supported on a guide rail 104f (supported on the second support portion 104 (upper surface 104b)) so as to be movable in the minor axis direction (see arrow AR6 in FIG. 10). V 10. In this way, the other end A2 of the reaction vessel 100 is aligned along the long axis AX 100 In addition to the direction, the rotation axis AX V The actuator is supported so as to be rotatable about a vertical axis and movable in a minor axis direction (see arrow AR6 in FIG. 10).

[0109] In this way, the other end A2 of the reaction vessel 100 is aligned along the long axis AX 100 In addition to the direction, the rotation axis AX V The advantages of supporting the actuator in a state in which it can rotate around the vertical axis and move in the minor axis direction (see arrow AR6 in FIG. 10) are as follows.

[0110] When the above stress (see arrow AR5 in FIG. 7) occurs, friction occurs between the second support portion 104 (projection portion 104a) and the flange portion 109 (recess 109a), causing the reaction vessel 100 (other end side A2) to rotate around the long axis AX 100 There is a risk of directional movement being impeded.

[0111] If the deformation becomes even larger (if the stress becomes even larger), the other end side A2 of the reaction vessel 100 may tilt (see FIG. 11(b)), and the reaction vessel 100 may twist (see FIG. 11(a)). FIG. 11(a) is a diagram showing the reaction vessel 100 in a twisted state, and FIG. 11(b) is a diagram showing the reaction vessel 100 in a tilted state. Such twisting and tilting are likely to occur at the other end side A2 or the middle part A3.

[0112] Therefore, by adopting the configuration shown in Fig. 10, it becomes possible to suppress twisting of the reaction vessel 100 (see Fig. 11(c) and Fig. 11(d)). Fig. 11(c) is a diagram showing a state in which twisting of the reaction vessel 100 is suppressed, and Fig. 11(d) is a diagram showing a state in which tilting of the reaction vessel 100 is suppressed.

[0113] In the above-mentioned first and second embodiments, the temperature control section (temperature control area 110, etc.) controls the temperature of the reaction vessel 100 along the long axis AX 100 Although an example in which control is performed for each of the regions having different directions has been described, the present invention is not limited to this. That is, the number of regions for which the temperature control section (temperature control region 110, etc.) controls the temperature is not limited to a plurality of regions, and may be one region.

[0114] In addition, in the above-mentioned first and second embodiments, an example using the fluid supply unit (first fluid inlet 131, first fluid outlet 132, first valve 134, etc.) has been described, but the present invention is not limited to this. That is, a part or the whole of the fluid supply unit (first fluid inlet 131, first fluid outlet 132, first valve 134, etc.) may be omitted.

[0115] In the above-mentioned first and second embodiments, the driving device 150 is provided at one end side A1 of the reaction vessel 100 and connected to one end side B1 of the transport mechanism 120 (e.g., a screw), but the present invention is not limited to this. Another driving device may be used as a device for driving the transport mechanism 120.

[0116] The invention made by the inventor has been specifically described above based on the embodiments, but it goes without saying that the present invention is not limited to the embodiments already described, and various modifications are possible without departing from the gist of the invention.
