<Embodiment 1>
The main configuration of the reaction apparatus according to the first embodiment will be described with reference to FIG. 1. FIG. 1 is a side cross-sectional view of a reaction device 10 according to the first embodiment. The reaction apparatus 10 is an apparatus for producing a reaction product by applying conditions such as predetermined physical stimulation to raw materials.

The types and conditions of the raw materials and reaction products are not particularly limited, but they may be inorganic substances such as metal oxides or metal sulfides containing lithium as one of the components, or organic substances such as hydrocarbons. Good too. Further, the shape and size of the raw materials and reaction products are not particularly limited, but when the shape is blocky, the diagonal length is preferably 0.1 mm to 50 mm, more preferably 1 to 20 mm. Further, when the raw material or reaction product is in the form of a lump, the ratio of diagonal lengths (aspect ratio) is preferably 1 to 10, more preferably 1.3 to 1.8. The reactor 10 mainly includes a kiln section 100, a contact area 105, a fluid supply device 120, and a fluid suction device 130. In addition to the above configuration, the reaction apparatus 10 also includes a feeder 140, a kiln foot 150, a drive device 160, and the like.

The main components of the kiln section 100 include a raw material supply port 101, a discharge port 102, and a cylinder section 103. The raw material supply port 101 receives the raw material R10 supplied to one end side. The delivery port 102 delivers the reaction product R11 to the other end. The cylindrical portion 103 is a cylindrical member having a raw material supply port 101 at one end and a delivery port 102 at the other end, and extends rotatably along the central axis C10.

The kiln section 100 applies a predetermined temperature in the range of room temperature to 1500 degrees Celsius to the raw materials it receives. Therefore, the main structure of the kiln section 100 is formed of a member that can withstand this temperature. That is, the kiln section 100 is made of, for example, an alloy containing at least one of nickel, cobalt, chromium, iron, copper, aluminum, titanium, tungsten, niobium, tantalum, molybdenum, silicon, boron, and carbon as a component, or alumina or zirconia. It is formed of ceramics containing metal oxides, nitrides such as silicon nitride, carbides such as titanium carbide, borides such as chromium boride, or carbon such as crystalline graphite or fiber-reinforced graphite, or is formed of the above alloys and the above. It can be formed from a composite material, a coating material, or a bonding material that combines ceramics and any of the above-mentioned carbons.

The kiln section 100 may be installed at an angle so that the supply port side of the cylinder section 103 is higher than the delivery port side. In the kiln section 100 shown in FIG. 1, the central axis C10 of the cylindrical section 103 has an inclination of a predetermined angle θ with respect to the horizontal direction. Thereby, the kiln section 100 is configured such that the received predetermined raw material R10 is conveyed to the outlet 102 along the central axis C10 while contacting the inner wall of the cylindrical section 103. Note that the angle θ can be selected from the range of −90 degrees to +90 degrees.

A feeder 140 is engaged with the raw material supply port 101 of the kiln section 100 shown in FIG. 1 via a bearing 104. The feeder 140 rotatably supports the raw material supply port 101 side of the kiln section 100. That is, the feeder 140 is a support section that supports the kiln section 100. The feeder 140 receives the raw material R10 from the raw material input port 141, which is an opening provided above, and guides the received raw material R10 to the raw material supply port 101.

Further, a kiln foot 150 is engaged with the outlet 102 of the kiln section 100 via a bearing 104 . The kiln foot 150 rotatably supports the outlet 102 side. That is, the kiln foot 150 is a support part that supports the kiln section 100. Further, the kiln foot 150 has a reaction product outlet 151, and the reaction product R11 sent out from the delivery port 102 is sent out from the reaction product outlet 151. Furthermore, kiln foot 150 secures fluid supply device 120 and fluid suction device 130.

Note that the feeder 140 may fix at least one of the fluid supply device 120 and the fluid suction device 130 in place of or together with the kiln foot 150. That is, at least one of the feeder 140 and the kiln foot 150 serves as a support for fixing the fluid supply device 120 and the fluid suction device 130. At this time, for example, the feeder 140 may fix the fluid supply device 120 and the kiln foot 150 may fix the fluid suction device 130, or vice versa.

The fluid supply device 120 is a device for supplying a predetermined fluid to the kiln section 100. The predetermined fluid is a gas or a liquid, but may also include a solid such as a powder if it has fluidity. The fluid supply device 120 has a fluid supply pipe 121 and a fluid supply port 122 as main components. In addition to the above-described configuration, the fluid supply device 120 may include a storage section that stores a predetermined fluid and a pump that pumps this fluid.

The fluid supply pipe 121 is a fluid transport pipe configured to extend from one end side or the other end side of the kiln section 100 to the inside of the cylindrical section 103. In FIG. 1, the fluid supply pipe 121 is fixed to the kiln foot 150 and extends from the kiln foot 150 toward the cylindrical portion 103 of the kiln section 100.

The fluid supply port 122 is an opening provided in the fluid supply pipe 121 so that a predetermined fluid pumped by the fluid supply pipe 121 can be released into the cylindrical portion 103 . The fluid supply port 122 shown in FIG. 1 is provided with a plurality of holes. However, the fluid supply port 122 may be a single hole or may be a porous member through which a predetermined fluid can pass.

The fluid suction device 130 is a device for sucking fluid present inside the kiln section 100 and discharging it to the outside of the kiln section 100. The fluid sucked by the fluid suction device 130 includes, for example, the fluid supplied by the fluid supply device 120 that has come into contact with the raw material R10. The fluid suction device 130 mainly includes a fluid suction tube 131 and a fluid suction port 132. In addition to the above-described configuration, the fluid suction device 130 may include a suction pump for actively suctioning fluid, a forced exhaust device, and the like.

The fluid suction port 132 is an opening provided to be able to suction the fluid that has passed through the contact area 105. The fluid suction pipe 131 is a pipe that pumps the fluid sucked from the fluid suction port 132 to the outside of the kiln section 100. In FIG. 1, the fluid suction tube 131 is fixed to the kiln foot 150 and extends from the kiln foot 150 toward the cylindrical portion 103 of the kiln section 100.

The fluid supply device 120 and the fluid suction device 130 described above are made of, for example, an alloy containing at least one of nickel, cobalt, chromium, iron, copper, aluminum, titanium, tungsten, niobium, tantalum, molybdenum, silicon, boron, and carbon as a component. It is formed from ceramics containing metal oxides such as alumina and zirconia, nitrides such as silicon nitride, carbides such as titanium carbide, borides such as chromium boride, and carbon such as crystalline graphite and fiber-reinforced graphite. Alternatively, it may be formed of a composite material, a coating material, or a bonding material combining any of the above alloys, the above ceramics, and the above carbons.

Note that the fluid supply device 120 and the inner wall of the cylindrical portion 103 remain separated from each other. Similarly, the fluid suction device 130 and the inner wall of the cylindrical portion 103 remain separated from each other. Thereby, the fluid supply device 120 and the fluid suction device 130 are configured so as not to interfere with the rotation of the kiln section 100.

The fluid supply device 120 and the fluid suction device 130 may be fixed to the kiln foot 150 in a connected state, or may be fixed to the kiln foot 150 independently. The fluid supply device 120 and the fluid suction device 130 may be fixed to the kiln foot 150 and further supported by the feeder 140.

As shown in FIG. 1, the fluid suction port 132 and the fluid supply port 122 are preferably spaced apart along a direction parallel to the central axis C10. In FIG. 1, the fluid supply port 122 is located on the upstream side of the cylindrical portion 103, and discharges fluid downward where the raw material R10 is present. Further, the fluid suction port 132 is located on the downstream side away from the fluid supply port 122 in the direction along the central axis C10, and sucks the fluid present below. With such a configuration, the reaction apparatus 10 preferably provides a contact region 105 between the fluid supply port 122 and the fluid suction port 132, which is a region where the fluid supplied from the fluid supply port 122 and the raw material R10 come into contact. I can do it.

The contact area 105 is an area where the fluid discharged from the fluid supply port 122 and the raw material R10 come into contact. The area indicated by the thick two-dot chain line in FIG. 1 is the contact area 105. In the contact area 105, the raw material R10 contacts the fluid supplied from the fluid supply device 120 while rolling and flowing. As a result, the raw material R10 becomes a predetermined reaction product R11, which is conveyed to the outlet 102. Further, the fluid supplied from the fluid supply port 122 passes through the contact area 105 and is then sucked into the fluid suction port 132 located on the downstream side of the contact area 105.

The temperature control device 110 controls the temperature of the kiln section 100 by heating or cooling the outer circumference of the kiln section 100. The temperature control device 110 performs heating in a range from room temperature to about 1500 degrees Celsius, for example. The temperature control device 110 includes a heating device surrounding the cylindrical kiln section 100, for example. The heating device includes any heater whose temperature can be controlled, such as an induction heater, a sheath heater, a coil heater, or a ceramic heater. Alternatively, the heating device may be one that circulates a heated fluid by burning gas. Temperature control device 110 may include a control device for controlling the temperature of kiln section 100. For example, the temperature control device 110 may include a thermometer at a predetermined position in the kiln section 100 for monitoring the temperature.

Note that a plurality of temperature control devices 110 may be installed along the extending direction of the kiln section 100. For example, the reactor 10 has a first temperature control section 110A located on a side relatively close to the raw material supply port 101 and further away from the raw material supply port 101. The second temperature control section 110B may be provided on the side relatively close to the second temperature control section 110B. In this case, for example, the internal temperature at the raw material supply port 101 becomes room temperature in the region of the raw material supply port 101. Further, the first temperature control section 110A controls the internal temperature of the kiln section 100 to, for example, 500 degrees. Further, the second temperature control section 110B controls the internal temperature of the kiln section 100 to, for example, 1500 degrees.

In this case, the reactor 10 degreases the raw material R10 in the temperature range (500 degrees) set by the first temperature control unit 110A, and degreases the raw material R10 in the temperature range (1500 degrees) set by the second temperature control unit 110B. Raw material R10 may be sintered. As described above, the reaction apparatus 10 has a plurality of temperature control sections, so that a plurality of temperature profiles can be set along the stretching direction of the kiln section 100. With the above-described configuration, the reaction apparatus 10 rotates the kiln section 100 and heats the kiln section 100. When heat is transferred to the cylinder section 103, this heat is radiated into the inside of the kiln section 100.

The drive device 160 includes a motor and a drive force transmission section 161 that fits into a drive shaft protruding from the motor. In the drive device 160, the driving force transmission section 161 drives the driven section 106 to rotate the kiln section 100. The driving force transmission section 161 and the driven section 106 are, for example, gears configured to mesh with each other. With such a configuration, the drive device 160 rotates the kiln section 100 around the central axis C10. Thereby, the kiln section 100 transports the raw material R10 received from the raw material supply port 101 to the delivery port 102 while rolling it.

Next, with reference to FIG. 2, the process executed by the reaction apparatus 10 will be described. FIG. 2 is a flowchart of the process (reaction product manufacturing method) performed by the reaction apparatus. The flowchart shown in FIG. 2 is executed using the reaction apparatus 10, for example, by a user who uses the reaction apparatus 10 to produce a reaction product.

First, a user prepares the reaction apparatus 10 including the kiln section 100 (step S11). The reaction device 10 prepared by the user has the configuration described above.

Next, the user operates the reaction device 10 and causes the temperature control device 110 to heat the kiln section 100. That is, temperature control device 110 heats the inside of kiln section 100 to a predetermined temperature (step S12).

Next, the user operates the reaction device 10 and causes the fluid supply device 120 to supply a predetermined fluid. The user also operates the reaction device 10 to cause the fluid suction device 130 to suction fluid. As a result, the fluid supply device 120 releases a predetermined fluid from the fluid supply port 122 provided inside the cylindrical portion 103, and the fluid suction device 130 discharges a predetermined fluid from the fluid suction port 132 provided inside the cylindrical portion 103. The fluid inside the cylindrical portion 103 is suctioned from the cylindrical portion 103 (step S13).

Next, the user supplies the raw material R10 to the kiln section 100 from the raw material supply port 101 (step S14). Note that the user supplies the raw material R10 to the raw material supply port 101 by charging the raw material R10 into the feeder 140.

Next, the user rotates the kiln section 100 to transport the raw material R10 downstream and bring it into contact with a predetermined fluid in the contact area 105 (step S15). Note that the user preferably starts the rotation of the kiln section 100 after step S11 and before step S12 in order to convey the raw material R10 supplied to the kiln section 100 downstream. At this time, the reaction device 10 rotates the kiln section 100 by driving the drive device 160.

Next, the user causes the reaction product to be delivered from the delivery port 102 (step S16).

The method for producing a reaction product carried out by the reaction apparatus 10 has been described above. The above-mentioned method is shown along the flow from the reaction device 10 producing the reaction product R11 from the raw material R10 to delivering the produced reaction product R11. However, the reaction apparatus 10 may perform the rotation operation of the kiln section 100 in step S15, for example, before step S12.

Although Embodiment 1 has been described above, the configuration of Embodiment 1 is not limited to that described above. The reaction device 10 may have a configuration in which the fluid flows from the downstream side to the upstream side. The reactor 10 also has a fluid supply port 122 in the center of the kiln section 100, a first fluid suction port 132 on the upstream side of the fluid supply port 122, and a first fluid suction port 132 on the downstream side of the fluid supply port 122. A second fluid suction port 132 may be provided at the second fluid suction port 132 . That is, in this case, the fluid supplied from the fluid supply port 122 to the kiln section 100 may be branched into one directed toward the first fluid suction port 132 and one directed toward the second fluid suction port 132. With the above configuration, the reaction apparatus 10, which is a rotary kiln, can continuously and efficiently bring the raw material R10 into contact with the fluid in the contact area 105. Therefore, according to Embodiment 1, it is possible to provide a reaction apparatus and the like that efficiently manufacture a desired product.

<Embodiment 2>
Next, a second embodiment will be described. Embodiment 2 has a function of regulating the flow of fluid inside the kiln section 100.

FIG. 3 is a side cross-sectional view of the reaction device 20 according to the second embodiment. The reaction device 20 shown in FIG. 3 differs from the reaction device 10 in the shapes of the fluid supply port 122 and the fluid suction port 132. Further, the reaction apparatus 20 differs from the first embodiment in that it includes a support member 170, a baffle plate 171, and a baffle plate 172.

The fluid supply port 122 in the second embodiment is set to form an angle α with the central axis C10. As a result, the fluid supply port 122 has an opening in a direction facing the baffle plate 172. In other words, the fluid discharged from the fluid supply port 122 hits the baffle plate 172 and its flow is regulated by the baffle plate 172 . The fluid is thereby guided to the contact area 105 and comes into contact with the raw material R10.

The fluid suction port 132 in the second embodiment is set to form an angle β with the central axis C10. As a result, the fluid suction port 132 has an opening in the direction facing the baffle plate 171. In other words, the fluid that has passed through the contact area 105 is regulated by the baffle plate 171 and then sucked into the fluid suction port 132.

The support member 170 is a member that extends from the kiln foot 150, which is a support portion, to the inside of the cylindrical portion 103, and supports the baffle plate 171 and the baffle plate 172. Note that the support member 170 may be configured by combining the fluid supply pipe 121 or the fluid suction pipe 131. Support member 170 may be fixed to kiln foot 150 and further supported by feeder 140. The support member 170 may be fixed to the feeder 140, which is a support portion, and may extend from the feeder 140 to the cylindrical portion 103. Further, the support member 170 may be fixed to the feeder 140 and further supported by the kiln foot 150.

The baffle plate 171 is a plate-shaped member disposed between the fluid suction port 132 and the delivery port 102. The baffle plate 171 is supported by the support member 170 so as not to hinder the rotation of the kiln section 100. The baffle plate 171 restricts the flow of fluid in a direction parallel to the central axis C10 outside the contact area 105, which is a space formed between the fluid supply port 122 and the fluid suction port 132 in the cylindrical portion 103. That is, by arranging the baffle plate 171, the reaction device 20 can suitably guide the fluid that has passed through the contact area 105 to the fluid suction port 132 and suck this fluid.

The baffle plate 172 is a plate-shaped member disposed between the raw material supply port 101 and the fluid supply port 122, and is supported by the support member 170 similarly to the baffle plate 171. The baffle plate 172 restricts the flow of fluid in the direction parallel to the central axis C10 outside the contact area 105 in the cylindrical portion 103. That is, by arranging the baffle plate 172, the reaction device 20 can preferably guide the fluid discharged by the fluid supply port 122 to the contact area 105.

As described above, the baffle plate 171 and the baffle plate 172 are provided at one end side and the other end side, respectively, so as to sandwich the fluid supply port 122 and the fluid suction port 132 along the direction parallel to the central axis C10. There is. Thereby, the reaction device 20 can suitably form the contact region 105 and bring the fluid and the raw material R10 into contact in the contact region 105. Furthermore, the reaction device 20 can efficiently suck the fluid after contacting the raw material R10.

Note that the shape of the baffle plate in this embodiment may have an uneven or curved shape in order to achieve the purpose of this embodiment. The upper portions of the baffle plates 171 and 172 shown in FIG. 3 are bent toward the upstream side. This is for the purpose of forming a suitable flow of the fluid supplied from the fluid supply device 120. Further, the lower portions of the baffle plate 171 and the baffle plate 172 are bent toward the downstream side. The purpose of this is to smoothly transport the raw material R10 to the downstream side. The baffle plate can have various shapes other than those described above.

Next, the configuration of the baffle plate will be further described with reference to FIG. 4. FIG. 4 is a front cross-sectional view of the reaction device 20 according to the second embodiment. FIG. 4 is a cross-sectional view of the IV-IV cross section of FIG. 3 observed from a direction parallel to the central axis C10.

In the reaction apparatus 20, a temperature control device 110 is provided on the outer periphery of a kiln section 100 configured in an annular shape. The reaction device 20 also includes a support member 170, a baffle plate 171, a fluid supply device 120, and a fluid suction device 130 inside the kiln section 100.

A fluid supply device 120 and a fluid suction device 130, which are tubular holes, are formed inside the support member 170 along the stretching direction. Further, in the cross-sectional view shown in FIG. 4, the fluid suction device 130 protrudes from the lower part of the support member 170 and forms a fluid suction port 132.

The baffle plate 171 has a disk shape and is spaced apart from the inner wall of the cylindrical portion 103 to the extent that it does not come into contact with the inner wall of the cylindrical portion 103 . In addition, the distance from the inner wall of the cylindrical portion 103 is relatively large at the lower part of the baffle plate 171 in order to ensure a space for the raw material R10 to pass through. As a result, the fluid appropriately contacts the raw material R10 in the contact area 105, and is further regulated by the baffle plate 171 to be sucked from the fluid suction port 132. Further, the raw material R10 suitably contacts the fluid in the contact area 105, and is further conveyed downstream from the space provided under the baffle plate 171.

The second embodiment has been described above. With the above configuration, the reaction apparatus 20 can efficiently produce the reaction product R11. That is, according to this embodiment, it is possible to provide a reaction apparatus and the like that efficiently produce a desired product.

<Embodiment 3>

The reaction device 30 differs from the second embodiment in the configurations of a fluid supply device, a fluid suction device, baffle plates, and contact areas. Furthermore, the reactor 30 differs from the second embodiment in the aspect of the temperature control device 110.

Fluid supply device 120 in this embodiment has a plurality of first fluid supply ports 122A and second fluid supply ports 122B that can separately supply a plurality of fluids at different positions along a direction parallel to central axis C10. . This allows reactor 30 to supply fluid separately at multiple different locations.

Further, the reaction apparatus 30 in this embodiment includes a baffle plate 173. The baffle plate 173 restricts the flow of fluid in a direction parallel to the central axis C10 between the first fluid supply port 122A and the second fluid supply port 122B. The baffle plate 173 allows the reaction device 30 to separate and control the flow of the fluid discharged from the first fluid supply port 122A and the flow of the fluid discharged from the second fluid supply port 122B.

Furthermore, the fluid suction device 130 in this embodiment has a first fluid suction port 132A and a second fluid suction port 132B. The first fluid suction port 132A is provided to suck the fluid released by the first fluid supply port 122A. The second fluid suction port 132B is provided to suck the fluid released by the second fluid supply port 122B. That is, the fluid suction device 130 has a plurality of fluid suction ports provided corresponding to each of the plurality of fluid supply ports.

With the above-described configuration, the reaction device 30 includes a first contact area 105A and a second contact area 105B. That is, in the first contact area 105A, the fluid supplied from the first fluid supply port 122A comes into contact with the raw material R10, and is then sucked by the first fluid suction port 132A. The first contact area 105A is sandwiched between a baffle plate 172 and a baffle plate 173. Thereby, the first contact area 105A can suitably bring the fluid into contact with the raw material R10.

Further, in the second contact area 105B, the fluid supplied from the second fluid supply port 122B contacts the raw material R10, and is then sucked by the second fluid suction port 132B. The second contact area 105B is sandwiched between the baffle plate 173 and the baffle plate 171. Thereby, the second contact area 105B can suitably bring the fluid into contact with the raw material R10.

In the reaction apparatus 30 according to the present embodiment, the fluid supply device 120 is configured such that different types of fluids (for example, a first fluid and a second fluid) flow through the first fluid supply port 122A and the second fluid supply port 122B, respectively. may be configured. That is, in this case, the fluid supply device 120 includes a first fluid supply pipe 121A and a first fluid supply port 122A that supply the first fluid, and a second fluid supply pipe 121B and a second fluid supply port 122B that supply the second fluid. and has. In this case, the raw material R10 and the first fluid come into contact with each other in the first contact area 105A. In the second contact region 105B, the raw material R10 contacts the second fluid after contacting the first fluid downstream of the first contact region 105A. The fluid suction device 130 then suctions the first fluid in the first contact area 105A and suctions the second fluid in the second contact area 105B.

Note that the fluid suction device 130 may include a first fluid suction tube 131A corresponding to the first fluid suction port 132A and a second fluid suction tube 131B corresponding to the second fluid suction port 132B. . Such a configuration allows the reactor 30 to separately aspirate fluids in different contact areas.

With the above-described configuration, the reaction device 30 has a baffle plate 173 between the first contact area 105A and the second contact area 105B for partitioning the flow of the first fluid and the flow of the second fluid. Therefore, each contact area can be suitably separated and a desired reaction can occur in each area.

Further, in this case, the temperature control device 110 that controls the temperature of the kiln section 100 includes a first temperature control section 110A that controls the temperature of the first contact area 105A, and a second temperature control section that controls the temperature of the second contact area 105B. 110B. This allows the temperature control device 110 to separately perform temperature control on a plurality of contact areas. For example, in the temperature control device 110, the first temperature control section 110A controls the temperature of the first contact area 105A to be 500 degrees, and the second temperature control section 110B controls the temperature of the second contact area 105B to 1000 degrees. Control as follows.

The third embodiment has been described above. Note that although the reaction device 30 described above has two contact areas 105, the reaction device 30 may have three or more different contact areas. Further, the temperature control device 110 may include a cooling device that cools the downstream side of the baffle plate 171 in the configuration shown in FIG. 5, for example. In addition, one fluid supply port 122 and one fluid suction port 132 were arranged corresponding to each of the contact areas 105 of the reaction device 30 described above. However, the configuration of the contact area 105 and the corresponding fluid supply port 122 and fluid suction port 132 is not limited to this. That is, in the reaction device 30, the number of fluid supply ports 122 corresponding to one contact area 105 may be one or more than one. Further, in the reaction device 30, the number of fluid suction ports 132 corresponding to one contact area 105 may be one or more than one.

With the above-described configuration, the reaction apparatus 30 can set a plurality of regions each having a different environment in one kiln section 100. Therefore, according to Embodiment 3, it is possible to provide a reaction apparatus and the like that can efficiently produce a desired product.

<Embodiment 4>
Next, Embodiment 4 will be described. FIG. 6 is a side cross-sectional view of the reaction device 40 according to the fourth embodiment. The reaction apparatus 40 according to the fourth embodiment differs from the second embodiment in the form of the baffle plate.

Support member 170 in this embodiment is fixed to kiln foot 150 and supported by feeder 140. With such a configuration, the support member 170 can support any baffle plate formed along the extending direction of the kiln section 100.

The reaction device 40 has a baffle plate 174 and a baffle plate 175. The baffle plate 174 restricts the flow of fluid in the contact area 105 along a direction parallel to the central axis C10.

In the reaction device 40, the fluid discharged from the fluid supply port 122 flows from the upstream side to the downstream side. The raw material R10 supplied from the raw material supply port 101 is also conveyed toward the delivery port 102 on the downstream side. The baffle plate 174 restricts the above-mentioned flow in the contact area 105 of the cylindrical portion 103. That is, the baffle plate 174 may be configured such that the cross-sectional area of the flow path through which the fluid passes in the contact area 105 changes.

As a result, the flow velocity and flow direction of the fluid discharged from the fluid supply port 122 in the contact area 105 can change. Alternatively, the flux of the fluid discharged from the fluid supply port 122 may change in the contact region 105 along the flow direction. Further, in accordance with this, the moving speed and moving direction of the raw material R10 that comes into contact with the fluid may change.

Note that the baffle plate 174 may restrict the flow of fluid along the rotational direction of the kiln section 100 in addition to the direction parallel to the central axis C10. For example, the baffle plate 174 may helically restrict the flow of fluid. With the above-described configuration, the baffle plate 174 can suitably restrict the flow of fluid with respect to the rolling and flowing raw material R10.

A specific example shown in FIG. 6 will be described. In the contact area 105, the baffle plate 174 is formed so that the distance from the cylindrical portion 103 gradually increases from upstream to downstream. On the relatively upstream side of the contact area 105, the flux formed by the lower surface of the baffle plate 174 and the inner wall of the cylindrical portion 103 has a cross-sectional area D10. At the center of the contact area 105, the flux formed by the lower surface of the baffle plate 174 and the inner wall of the cylindrical portion 103 has a cross-sectional area D20 larger than the cross-sectional area D10. Further, at the downstream end of the contact area 105, the flux formed by the lower surface of the baffle plate 174 and the inner wall of the cylindrical portion 103 has a cross-sectional area D30 smaller than the cross-sectional area D20.

With the above configuration, in the contact area 105, the flow velocity of the fluid decreases from the upstream toward the center, and the residence time of the raw material R10 and the fluid becomes relatively long in the center. Thereby, the reaction device 40 can make the contact time between the fluid and R10 in the contact region 105 relatively long. Therefore, according to Embodiment 4, it is possible to provide a reaction apparatus and the like that promote the reaction for producing a desired product and efficiently produce the product.

Further, the baffle plate 174 shown in FIG. 6 restricts the fluid below the fluid suction port 132 between the contact area 105 and the outlet 102 in a direction parallel to the central axis C10. As a result, the fluid and the reaction products generated after passing through the contact area 105 smoothly move to the outlet 102 . Note that at the outlet 102, the reaction product R11 falls to the reaction product outlet 151 due to its own weight, and the fluid is sucked into the fluid suction port 132.

Further, the baffle plate 175 shown in FIG. 6 is located between the raw material supply port 101 and the fluid supply port 122, and restricts the inflow of outside air flowing in from the raw material supply port 101. Further, the baffle plate 175 forms a gap between the baffle plate 175 and the cylindrical portion 103 at its lower part. Thereby, the baffle plate 175 does not prevent the raw material R10 from flowing in while suppressing the inflow of outside air. Further, the baffle plate 175 suitably guides the fluid discharged from the fluid supply port 122 located on the upstream side to the contact area 105.

<Embodiment 5>
Next, a fifth embodiment will be described with reference to FIG. FIG. 7 is a configuration diagram of a reaction system according to the fifth embodiment. The reaction system 1 shown in FIG. 7 is a system in which two reaction devices 10, that is, a first reaction device 10A and a second reaction device 10B are connected in series. FIG. 7 schematically shows a state in which the first reaction device 10A and the second reaction device 10B are connected. In the reaction system 1, a reaction product outlet 151A of the reaction product in the first reaction device 10A and a raw material input port 141B in the second reaction device 10B are connected.

The first reaction device 10A shown in the figure generates a reaction product A by applying a predetermined physical stimulus A to the raw material R10 received from the raw material input port 141A. The first reaction device 10A sends out the generated reaction product A from the reaction product outlet 151A.

The second fluid control region 140A receives the reaction product A sent from the reaction product outlet 151A of the first reaction device 10A into the raw material input port 141B. The second reaction device 10B generates a reaction product B from a reaction product A by applying a predetermined physical stimulus B. The second reaction device 10B sends out the generated reaction product B from the reaction product outlet 151B.

The fifth embodiment has been described above. In addition, in the above-mentioned reaction system 1, one or both of the first reaction device 10A and the second reaction device 10B may be any one of the reaction device 20, the reaction device 30, or the reaction device 40. Moreover, the reaction system 1 may be one in which three or more reaction devices are connected. With such a configuration, the reaction system 1 according to the fifth embodiment can continuously apply a plurality of physical stimuli such as stirring, rolling, heating, and cooling to the raw material. Moreover, with such a configuration, the reaction system 1 allows flexible arrangement and flexible system configuration of the system itself. That is, according to Embodiment 5, it is possible to provide a reaction system that efficiently produces a desired product that requires multiple reactions.

<Embodiment 6>
Next, a sixth embodiment will be described with reference to FIG. FIG. 8 is a configuration diagram of a reaction system according to Embodiment 6. The reaction system 2 shown in FIG. 8 has a granulation device 210 and a reaction device 10 as main components.

The granulator 210 applies pressure to the raw material, which is powder or granules, to produce granules. The granulated product is produced by applying a pressure of, for example, 10 megapascals to 700 megapascals to a granulated material consisting of secondary particles of about several tens of microns to several hundred microns. The means for applying pressure is not particularly limited, but in consideration of production efficiency, a continuous pressurization method using rotating mold rolls is preferable. Although the shape of the granules is not particularly limited, in consideration of ease of transportation in the granulator 210, it is desirable that the granules have a tablet shape such as a sphere, a disc, or an ellipsoid. As for the size of the granules, the diameter or length of the long side of the granules is generally from several millimeters to several tens of millimeters, but preferably 30 millimeters or less. Furthermore, considering the efficiency of the reaction in the granulator 210, it is desirable that the sizes of each granule are about the same. In addition, when pressurizing in the production of granules, for example, a small amount of binder resin having vinyl groups or imide groups is added for the purpose of improving granulation properties and improving the disintegration properties after the granules have reacted. Alternatively, a raw material mixed with an organic polymer binder in advance may be used. The granulator 210 supplies the manufactured granules to the raw material input port 141 .

When the reactor 10 receives the granules at the raw material input port 141, the reactor 10 supplies the received granules to the kiln section 100. The reaction device 10 applies a predetermined atmosphere and physical stimulation to the received granules to generate a reaction product. When the reaction device 10 generates a reaction product, it sends out the generated reaction product from the reaction product outlet 151.

The sixth embodiment has been described above. In the reaction system 2 according to the present embodiment, pressure is applied to the raw material in the granulating device 210, and then the raw material is stirred while being heated in the reaction device 10 in which the atmosphere is controlled. Thereby, the reaction system 2 can continuously produce, for example, an oxide-based solid electrolyte or a sulfide-based solid electrolyte. That is, according to Embodiment 6, a desired reaction product can be efficiently and continuously produced.
