  2. Description of the Related Art Conventionally, there is a reaction device that reacts with a substance contained in a fluid from a fluid flowing in a reaction path extending in one direction to adsorb the substance. This reaction path is formed by a reaction member that adsorbs a substance contained in the fluid.

  In the reaction apparatus, a fluid flowing in one direction flows into a reaction path extending in one direction, and flows out of the reaction path in one direction. Since the reaction path extends in one direction, the pressure loss of the fluid increases. On the other hand, if the flow path cross-sectional area of the reaction path is increased to reduce the pressure loss, the contact area where the fluid per unit flow rate contacts the reaction member decreases. For this reason, the reaction amount between the substance contained in the fluid and the reaction member decreases.

  An object of the present invention is to suppress a pressure loss of a fluid from increasing in comparison with a case where a fluid flowing in one direction flows into a reaction path extending in one direction and flows out from the reaction path in one direction. Another object of the present invention is to increase a reaction amount between a substance contained in a fluid and a reaction member.

The reaction device according to claim 1 of the present invention is configured such that a fluid that flows in one direction and that flows in one direction from an end and that flows in the one direction intersects with the inflow path that intersects the one direction. A plurality of fluids are arranged side by side in the one direction between the inflow path and the outflow path that extends in the one direction while being separated from the inflow path and the fluid that flows in the one direction flows out from an end. A reaction path formed by a reaction member that reacts with a substance contained in a fluid, wherein the length in the cross direction is L, and the flow path width is W1. Then, the reaction apparatus has the reaction path satisfying the following expression (1), and has a guide member that stops the flow of the fluid flowing through the inflow path in the one direction and guides the fluid to the reaction path. It is characterized by the following.
W1 / 2 ≦ L ≦ 10W1 (1)

  According to the above configuration, the fluid flows into the inflow channel from the end of the inflow channel extending in one direction, and flows in one direction. Further, the flow of the fluid flowing in the inflow path is stopped in one direction by the guide member, the flow direction is changed, and the fluid flows (is guided) in a plurality of reaction paths arranged side by side in one direction. A substance contained in the fluid flowing through each of the plurality of reaction paths reacts with a reaction member forming the reaction path. Further, the fluid flowing through each of the plurality of reaction paths changes its flow direction, flows into an outflow path extending in one direction, and flows out of the outflow path.

  As described above, a plurality of reaction paths are provided. Further, the fluid flowing from the inflow path to the reaction path changes the flow direction and flows into the reaction path. The fluid flowing from the reaction channel to the outflow channel changes the flow direction and flows into the outflow channel. Further, when the length of the reaction path in the cross direction is L and the flow path width of the reaction path is W1, the following equation (1) is satisfied.

                    W1 / 2 ≦ L ≦ 10W1 (1)

  For this reason, compared with the case where the fluid flowing in one direction flows into the reaction path extending in one direction and flows out from the reaction path in one direction, the pressure loss of the fluid is suppressed from increasing, and The amount of reaction between the contained substance and the reaction member can be increased.

  According to the above configuration, the reaction path and the outflow path are respectively formed on both sides of the inflow path. Therefore, the amount of reaction between the substance contained in the fluid and the reaction member can be increased as compared with the case where the reaction path and the outflow path are formed only on one side of the inflow path.

  The reactor according to claim 4 of the present invention is the reactor according to any one of claims 1 to 3, wherein a plurality of the inflow paths are formed, and a plurality of the outflow paths are formed. It is characterized by being alternately arranged with the outflow channel.

  According to the above configuration, a plurality of inflow paths are formed, and a plurality of outflow paths are formed, and the inflow paths and the outflow paths are alternately arranged. Therefore, the amount of reaction between the substance contained in the fluid and the reaction member can be increased as compared with the case where at least one of the outflow path and the outflow path is one.

  In the reactor according to claim 5 of the present invention, in the reactor according to any one of claims 1 to 4, a flow width of a portion of the inflow channel where the reaction channel faces is such that a fluid flows. It is characterized in that it narrows from the upstream side to the downstream side in the flow direction.

  According to the above configuration, the flow channel width of the portion where the reaction channel faces in the inflow channel becomes narrower from the upstream side to the downstream side in the flow direction of the fluid. Therefore, the difference between the flow rate of the fluid flowing from the inflow path to one reaction path and the flow rate of the fluid flowing to the other reaction path is reduced as compared with the case where the flow path width of the inflow path is constant. be able to.

It is characterized by widening from the upstream side to the downstream side in the flow direction.

  According to the configuration described above, the flow path width of the portion where the reaction path faces in the outflow path increases from the upstream side where the fluid flows to the downstream side. For this reason, the difference between the flow rate of the fluid flowing from one reaction path to the outflow path and the flow rate of the fluid flowing from the other reaction path to the outflow path is smaller than when the flow path width of the outflow path is constant. Can be reduced.

  The reactor according to claim 7 of the present invention is the reactor according to any one of claims 1 to 6, wherein the inflow path, the outflow path, and the reaction path are two parallel flat surfaces. It is characterized by being formed between.

  According to the above configuration, the inflow path, the outflow path, and the reaction path are formed between two parallel planes. For this reason, the inflow channel, the outflow channel, and the reaction channel can be formed with a simple configuration as compared with the case where the inflow channel, the outflow channel, and the reaction channel are formed using the pipe material.

The bottom plate 16 is an example of a guide member.

  In addition, one end of the reaction path 32 faces the other side of the inflow path 12 in the apparatus width direction. Specifically, on the other side in the apparatus width direction in the inflow path 12, the side plate 14B and the reaction path 32 are arranged in this order from the near side to the far side in the apparatus depth direction. In the present embodiment, the length of the side plate 14B in the apparatus depth direction and the flow path width of the inflow path 12 (B1 in FIG. 2A) are equal to the flow path width W1 of the reaction path 32 (details will be described later). On the other hand, the length is within ± 30 [%].

  In this configuration, the exhaust gas G1 flows into the inflow path 12 from the end on the near side in the apparatus depth direction, and flows through the inflow path 12 from the near side to the depth side in the apparatus depth direction.

[Outflow channel 22]
As shown in FIGS. 1 and 2C, the outflow channel 22 is separated from the inflow channel 12 in the device width direction and extends in the device depth direction. Furthermore, the shape of the outflow channel 22 cut in a direction orthogonal to the longitudinal direction is rectangular, and has the same shape in the device depth direction.

  The outflow channel 22 includes a side plate 24A on the other side of the outflow channel 22 in the device width direction (the opposite side to the inflow channel 12) and a side plate 24B on one side of the outflow channel 22 in the device width direction (the inflow channel 12 side). And a bottom plate 26 on the near side of the outflow channel 22 in the apparatus depth direction. Further, the side plates 24A and 24B and the bottom plate 26 are formed using a metal material. The bottom plate 26 is an example of a suppressing member.

  The other end of the reaction path 32 faces one side of the outflow path 22 in the apparatus width direction. Specifically, on one side in the apparatus width direction in the outflow path 22, the side plate 24B and the reaction path 32 are arranged in this order from the back side to the front side in the apparatus depth direction. In the present embodiment, the length of the side plate 24B in the apparatus depth direction and the flow path width of the outflow path 22 (B2 in FIG. 2C) are equal to the flow path width W1 of the reaction path 32 (details will be described later). The dimensions are similar.

  In this configuration, the processing gas G2 flows through the outflow path 22 from the near side to the back side in the apparatus depth direction, and flows out of the outflow path 22 from the end on the back side in the apparatus depth direction. Further, the bottom plate 26 suppresses the fluid flowing in the device depth direction from flowing into the outflow channel 22 from the end of the outflow channel 22.

[Reaction path 32]
As shown in FIGS. 1 and 2B, three reaction paths 32 are arranged side by side in the apparatus depth direction, and connect the inflow path 12 and the outflow path 22 in the apparatus width direction. The device width direction is an example of the cross direction.

  Further, the shape of the reaction path 32 cut in a direction perpendicular to the longitudinal direction is rectangular, and has the same shape in the apparatus width direction. One end of the reaction path 32 faces the inflow path 12, and the other end of the reaction path 32 faces the outflow path 22.

  The reaction path 32 is formed by reaction plates 34 and 36 on both sides of the reaction path 32 in the apparatus depth direction. Two reaction plates 34 are arranged so as to partition adjacent reaction paths 32. Further, two reaction plates 36 are arranged so as to sandwich the two reaction plates 34 from the apparatus depth direction. In the following description, for convenience, the three reaction paths 32 may be referred to as a reaction path 32A, a reaction path 32B, and a reaction path 32C in this order from the near side in the apparatus depth direction.

  In the present embodiment, the thickness of the reaction plate 36 is, for example, 0.1 μm or more and 4 mm or less, and the thickness of the reaction plate 34 is twice the thickness of the reaction plate 36. It has been. The width of the reaction path 32 (W1 in FIG. 2 (B)) is set to 0.1 [μm] or more and 5 [mm] or less.

                            W1 / 2 ≦ L ≦ 10W1 (1)

  The length L of the reaction path 32 is determined by the point of intersection of the center line of the reaction path 32 and a line connecting one end of the reaction plates 34 and 36 forming the reaction path 32 (one end of the reaction path 32). It is the length up to the intersection (the other end of the reaction path 32) between the center line of the path 32 and the line connecting the other ends of the reaction plates 34 and 36 forming the reaction path 32.

(Action)
Next, the operation of the reactor 10 will be described in comparison with the reactor 500 according to the comparative embodiment. First, the configuration of the reaction device 500 according to the comparative embodiment will be described.

[Configuration of reaction apparatus 500]
The reaction device 500 has a reaction path 532 extending in the depth direction of the device, as shown in FIG. As shown in FIG. 4B, the reaction path 532 is formed between two parallel planes 40A and 42A that are separated in the vertical direction of the apparatus. The reaction path 532 includes reaction plates 534 on both sides of the reaction path 532 in the apparatus width direction.

  The reaction plate 534 is formed using zeolite, and the thickness of the reaction plate 534 is the same as the thickness of the reaction plate 36 of the reaction device 10. The flow path width of the reaction path 532 (B4 in FIG. 4B) is the same as the flow path width W1 of the reaction path 32 in the reaction apparatus 10 (see FIG. 2B). Further, the length (L10 in FIG. 4) of the reaction path 532 is set to be three times the length L (see FIG. 1) of the reaction path 32 in the reaction apparatus 10.

  That is, the length L10 of the reaction path 532 is the same as the sum of the lengths L of the three reaction paths 32, and the volume of the flow path of the reaction path 532 of the reaction apparatus 500 is three. This is the same as the total flow volume in the reaction path 32. The contact area between the exhaust gas G1 flowing through the reaction path 532 of the reaction apparatus 500 and the reaction plate 534 is the same as the total contact area between the exhaust gas G1 flowing through the reaction path 32 of the reaction apparatus 10 and the reaction plates 34 and 36. It has been.

[Operation of reactor 500]
Exhaust gas G1 discharged from the factory containing nitrogen and carbon dioxide flows into the reaction path 532 from the end of the reaction path 532 of the reaction apparatus 500 shown in FIG. In the present embodiment, for example, the exhaust gas G1 at 25 [° C.] flows into the reaction path 532 at a space velocity of 300 [h ⁻¹ ].

  The exhaust gas G1 that has flowed into the reaction path 532 flows through the reaction path 532 to the depth side in the apparatus depth direction (arrow K1 in the figure). Furthermore, carbon dioxide contained in the exhaust gas G1 flowing through the reaction path 532 is adsorbed by the reaction plate 534 formed using zeolite. Further, the processing gas G2 from which the carbon dioxide has been removed from the exhaust gas G1 flows out from the end of the reaction path 532 on the far side in the apparatus depth direction.

  When recovering the carbon dioxide adsorbed by the reaction plate 534, for example, high-temperature air is caused to flow into the reaction path 532 from one end of the reaction path 532 of the reaction device 500. Then, carbon dioxide is desorbed from the reaction plate 534, and the desorbed carbon dioxide is recovered.

[Operation of reactor 10]
The exhaust gas G1 containing nitrogen and carbon dioxide discharged from the factory flows into the inflow path 12 from the front end in the depth direction of the inflow path 12 of the reaction apparatus 10 shown in FIG. In the present embodiment, as an example, the exhaust gas G1 at 25 [° C.] flows into the inflow path 12 at a space velocity of 300 [h ⁻¹ ]. The exhaust gas G1 that has flowed into the inflow path 12 flows through the inflow path 12 to the depth side in the apparatus depth direction (arrow M1 in the figure).

  A part of the exhaust gas G1 flowing through the inflow path 12 flows into the reaction path 32A with the flow direction changed to the apparatus width direction (arrow M2 in the figure). The exhaust gas G1 that has flowed into the reaction path 32A flows through the reaction path 32A in the width direction of the apparatus (arrow M3 in the figure). Further, carbon dioxide contained in the exhaust gas G1 flowing through the reaction path 32A is adsorbed by the reaction plates 34 and 36 formed using zeolite. The processing gas G2 from which the carbon dioxide has been removed from the exhaust gas G1 flows from the reaction path 32A into the outflow path 22 with the flow direction changed to the apparatus depth direction (arrow M4 in the figure). The processing gas G2 that has flowed into the outflow channel 22 flows through the outflow channel 22 to the depth side in the apparatus depth direction, and flows out of the outflow channel 22 from the depth side in the device depth direction (arrow M5 in the figure).

  Further, another part of the exhaust gas G1 flowing through the inflow path 12 flows into the reaction path 32B by changing the flow direction to the apparatus width direction (arrow M6 in the figure). Then, the exhaust gas G1 flowing into the reaction path 32B flows through the reaction path 32A in the width direction of the apparatus (arrow M7 in the figure). Further, carbon dioxide contained in the exhaust gas G1 flowing through the reaction path 32B is adsorbed by a pair of reaction plates 34 formed using zeolite. Further, the processing gas G2 from which the carbon dioxide has been removed from the exhaust gas G1 flows into the outflow path 22 from the reaction path 32B with the flow direction changed to the apparatus depth direction (arrow M8 in the figure). The processing gas G2 that has flowed into the outflow channel 22 flows through the outflow channel 22 to the depth side in the apparatus depth direction, and flows out of the outflow channel 22 from the depth side in the device depth direction (arrow M5 in the figure).

  Further, the remaining portion of the exhaust gas G1 flowing through the inflow path 12 is stopped by the bottom plate 16 in the apparatus depth direction, and is guided toward the reaction path 32C. Then, the exhaust gas G1 flows into the reaction path 32C with the flow direction changed to the apparatus width direction (arrow M9 in the figure). The exhaust gas G1 flowing into the reaction path 32C flows in the reaction path 32C in the width direction of the apparatus (arrow M10 in the figure). Further, carbon dioxide contained in the exhaust gas G1 flowing through the reaction path 32C is adsorbed by the reaction plates 34 and 36 formed using zeolite. Further, the processing gas G2 from which the carbon dioxide has been removed from the exhaust gas G1 flows from the reaction path 32C into the outflow path 22 with the flow direction changed to the apparatus depth direction (arrow M11 in the figure). The processing gas G2 that has flowed into the outflow channel 22 flows through the outflow channel 22 to the depth side in the apparatus depth direction, and flows out of the outflow channel 22 from the depth side in the device depth direction (arrow M5 in the figure).

  As a result, the flow rate of the exhaust gas G1 flowing through the reaction path 32A per unit time and the flow rate of the exhaust gas G1 flowing through the reaction path 32B per unit time are controlled by the exhaust gas G flowing through the reaction path 532 of the reactor 500 per unit time. It is smaller than the flow rate of G1. Further, the flow rate of the exhaust gas G1 flowing through the reaction path 32C per unit time is smaller than the flow rate of the exhaust gas G1 flowing through the reaction path 532 of the reaction device 500 per unit time. The length L of each of the reaction paths 32A, 32B, and 32C is set to 1/3 of the length L10 of the reaction path 532 of the reaction device 500. For this reason, in the reaction device 10, an increase in the pressure loss of the exhaust gas G <b> 1 flowing through the reaction passage 32 is suppressed as compared with the reaction device 500.

  Here, referring to FIG. 3, in the exhaust gas G1 flowing in the reaction path 632 extending in one direction (the left-right direction in the figure), carbon dioxide contained in the exhaust gas G1 forms a side of the reaction path 632. The state of being adsorbed by the pair of reaction plates 634 will be described. The reaction plate 634 is formed using zeolite.

  As shown in FIG. 3, when the exhaust gas G1 flows into the reaction path 632 from one end (the left end in the figure) of the reaction path 632, carbon dioxide contained in the exhaust gas G1 of the portion flowing on the reaction plate 634 side is removed. It reacts with 634 and is adsorbed. That is, the concentration of carbon dioxide in the exhaust gas G1 in the portion flowing on the side of the reaction plate 634 decreases. Specifically, the concentration of carbon dioxide decreases from the upstream side to the downstream side in the flow direction of the exhaust gas G1.

  Therefore, a boundary layer S1 occurs between the exhaust gas G1-1 having a high concentration of carbon dioxide and the exhaust gas G1-2 having a low concentration of carbon dioxide. Further, the boundary layer S1 and the reaction plate 634 are separated from each other in the flow channel width direction from the upstream side to the downstream side in the flow direction of the exhaust gas G1, and any distance between the boundary layer S1 and the reaction plate 634 is constant. (Saturates). Here, CFD (Computational Fluid Dynamics) analysis is performed, and based on the knowledge obtained from the analysis results, the distance from the inlet of the reaction path 632 to the position where the distance between the boundary layer S1 and the reaction plate 634 becomes constant (FIG. The middle L50) is about ten times the width of the reaction path 632 (W50 in the figure).

  Here, a region of the reaction path 632 that is 10 times or less the flow path width W50 from the inlet is defined as a region R1, and a region of the reaction path 632 that is longer than 10 times the flow path width W50 is defined as a region R2. And Then, in the region R1, the distance between the exhaust gas G1-1 having a higher concentration of carbon dioxide and the reaction plate 634 is shorter than in the region R2, and the carbon dioxide contained in the exhaust gas G1 is more effective than the reaction plate 634. Reacts and is adsorbed.

  In addition, from the viewpoint of ensuring a contact area where the exhaust gas G1 per unit flow rate contacts the reaction plate 634, the length of the reaction path 632 is at least half the length of the flow path width W50 from the inlet of the reaction path 632. Preferably, there is.

  As described above, the length of the reaction path 632 is half the length of the flow path width W50 from the viewpoint of increasing the amount of reaction between the carbon dioxide contained in the exhaust gas G1 and the reaction plate 634 formed using zeolite. It is preferable that the length is not more than 10 times the flow path width W50.

  Here, in the present embodiment, the length L of the reaction path 32 of the reaction device 10 satisfies the above-described equation (1). That is, the length L of the reaction path 32 is equal to or more than half the length of the flow path width W1 and equal to or less than 10 times the length of the flow path W1.

  In addition, three reaction paths 32 are formed in the reaction apparatus 10, and one reaction path 532 is formed in the reaction apparatus 500. Therefore, in the reaction device 10, the amount of reaction between the carbon dioxide contained in the exhaust gas G <b> 1 and the reaction plates 34 and 36 is increased as compared with the reaction device 500.

  Further, in the reaction apparatus 10, as shown in FIG. 1, the exhaust gas G1 flowing through the inflow path 12 changes its flow direction to the apparatus width direction and flows into the reaction path 32 (arrows M2, M6, M9 in FIG. 1). ). For this reason, in the reactor 10, the position at which the formation of the boundary layer S1 described above is started, as compared with the case where the exhaust gas G1 flows into the reaction path without changing the flow direction, in the flow direction of the exhaust gas G1. Move downstream. Therefore, the amount of adsorption (reaction amount) between the carbon dioxide contained in the exhaust gas G1 and the reaction plates 34 and 36 formed using zeolite is increasing.

  Further, in the reaction apparatus 10, as shown in FIG. 1, the exhaust gas G1 flowing through the reaction path 32 changes its flow direction to the apparatus width direction and flows into the outflow path 22 (arrows M4, M8, M11 in FIG. 1). ). For this reason, in the reaction device 10, the boundary layer S1 in the downstream portion of the flow path of the exhaust gas G1 in the reaction path 32 is more turbulent than in the case where the exhaust gas G1 flows out of the reaction path without changing the flow direction. Is done. Therefore, the amount of adsorption (reaction amount) between the carbon dioxide contained in the exhaust gas G1 and the reaction plates 34 and 36 formed using zeolite is increasing.

  In the reactor 10, the flow path length of the exhaust gas G1 flowing through the reaction path 32A, the flow path length of the exhaust gas G1 flowing through the reaction path 32B, and the flow path length of the exhaust gas G1 flowing through the reaction path 32C are the same. It becomes. For this reason, carbon dioxide is uniformly removed from the exhaust gas G1 as compared with the case where the flow path lengths are different.

  In the reactor 10, the inflow channel 12 and the outflow channel 22 extend in the depth direction of the device. As a result, the exhaust gas G1 flowing in the apparatus depth direction flows into the inflow path 12, and the processing gas G2 from which the carbon dioxide has been removed from the exhaust gas G1 flows out of the output path 22 in the apparatus depth direction. That is, the reaction device 10 causes the exhaust gas G1 flowing in from the device depth direction to flow out in the device depth direction as the processing gas G2.

  When recovering the carbon dioxide adsorbed by the reaction plates 34 and 36, for example, high-temperature air is caused to flow into the inflow path 12 of the reaction device 10. Then, carbon dioxide is desorbed from the reaction plates 34 and 36, and the desorbed carbon dioxide is recovered.

(Summary)
As described above, in the reactor 10, the pressure loss of the exhaust gas G1 flowing through the reaction path 32 is suppressed from increasing in comparison with the reactor 500, and the carbon dioxide contained in the exhaust gas G1 is suppressed. The amount (reaction amount) adsorbed on the reaction plates 34 and 36 can be increased.

  Further, in the reaction device 10, as described above, the exhaust gas G1 that has flowed in from the device depth direction can flow out as processing gas G2 in the device depth direction. That is, in the reaction device 10, the flow direction of the exhaust gas G1 flowing into the reaction device 10 and the flow direction of the processing gas G2 flowing out of the reaction device 10 can be the same.

  Further, the bottom plate 16 stops the flow of the exhaust gas G1 flowing through the inflow path 12 in the depth direction of the apparatus, and guides the exhaust gas G1 to the reaction path 32. Thereby, the exhaust gas G1 can be caused to flow into the reaction path 32 by changing the flow direction of all the exhaust gases G1 flowing through the inflow path 12.

  The bottom plate 26 prevents fluid such as the exhaust gas G1 flowing in the depth direction of the apparatus from flowing into the outflow channel 22 from the end of the outflow channel 22. That is, the flow of the fluid that blocks the processing gas G2 flowing from the reaction path 32 into the outflow path 22 is suppressed from flowing into the outflow path 22. Therefore, the flow rate of the processing gas G2 passing through the reaction path 32 can be increased as compared with the case where the fluid flowing in the apparatus depth direction flows into the outflow path from the end of the outflow path.

  The inflow channel 12, the outflow channel 22, and the reaction channel 32 are formed between two parallel flat surfaces 40A and 42A. For this reason, the inflow path 12, the outflow path 22, and the reaction path 32 can be formed with a simple configuration as compared with the case where the inflow path, the outflow path, and the reaction path are formed using the pipe material.

The processing gas G2 from which the carbon dioxide has been removed from the exhaust gas G1 flows from the reaction paths 32B and 132B into the outflow paths 22 and 122 (arrows M8-1 and M8-2 in the figure). The processing gas G2 that has flowed into the outflow passages 22 and 122 flows out from the end of the outflow passages 22 and 122 in the depth direction of the apparatus (arrows M5-1 and M5-2 in the figure).

  Further, the remaining portion of the exhaust gas G1 flowing through the inflow path 12 is stopped by the bottom plate 16 in the depth direction of the apparatus, and is guided toward the reaction paths 32C and 132C. Then, the exhaust gas G1 changes the flow direction to the apparatus width direction and flows into the reaction paths 32C and 132C (arrows M9-1 and M9-2 in the figure). The exhaust gas G1 flowing into the reaction paths 32C and 132C flows through the reaction paths 32C and 132C (arrows M10-1 and M10-2 in the figure).

The reactor 210 has an outflow channel 222 corresponding to the outflow channel 22, side plates 224A and 224B corresponding to the side plates 24A and 24B, and a bottom plate 226 corresponding to the bottom plate 26. Further, the reaction device 210 has a side plate 214B corresponding to the side plate 14B, a side plate 274B corresponding to the side plate 124B, and a bottom plate 216 corresponding to the bottom plate 16. The bottom plate 216 is an example of a guide member.

  In this configuration, the processing gas G2 flowing from the reaction paths 132A and 282A, the processing gas G2 flowing from the reaction paths 132B and 282A, and the processing gas G2 flowing from the reaction paths 132C and 282C flow into the outflow path 122.

  As described above, in the reaction device 210, two (plural) inflow channels 12, 122 are formed, and three (plural) outflow channels 22, 122, 222 are formed. They are arranged alternately. Thereby, carbon dioxide contained in the exhaust gas G1, the reaction plates 34, 36, the reaction plates 134, 136, and the reaction plates 234, 236 are compared with the case where at least one of the inflow path and the outflow path is one. The reaction amount (adsorption amount) with the reaction plates 284 and 286 can be increased. Other operations are the same as those of the second embodiment.

<Fourth embodiment>
An example of the reaction device according to the fourth embodiment of the present invention will be described with reference to FIGS. In addition, about 4th Embodiment, the part different from 3rd Embodiment is mainly demonstrated.

Further, in the reaction device 310, the flow path width of the portion where the reaction paths 232 and 282 face in the inflow path 212 becomes narrower from the upstream side to the downstream side in the flow direction of the exhaust gas G1.

  Furthermore, in the reaction device 310, the flow path width of the portion where the reaction path 32 faces in the outflow path 22 increases from the upstream side to the downstream side in the flow direction of the processing gas G2. Further, in the reaction device 310, the flow path width of the part where the reaction paths 132 and 282 face in the outflow path 122 increases from the upstream side to the downstream side in the flow direction of the processing gas G2. Further, in the reaction device 310, the flow path width of the part where the reaction path 232 faces in the outflow path 222 increases from the upstream side to the downstream side in the flow direction of the processing gas G2.

  Specifically, the positions of the reaction plates 34 and 36 in the device width direction, the positions of the reaction plates 134 and 136 in the device width direction, the positions of the reaction plates 234 and 236 in the device width direction, and the positions of the reaction plates 284 and 286 The position in the direction is shifted in the device width direction with respect to the adjacent reaction plate. Further, the outlets of the outlets 22, 122, 222 of the reactor 310 are wider than the outlets of the outlets of the reactor 210. Thereby, the widths of the inflow paths 12, 212 and the outflow paths 22, 122, 222 are changed.

  In the above configuration, in the reaction apparatus 310, the flow rate of the exhaust gas G1 flowing from the inflow path 12 into the reaction path 32A and the discharge flow into the reaction path 32B are smaller than in the case where the flow path width of the inflow path is constant. The difference between the flow rate of the gas G1 and the flow rate of the exhaust gas G1 flowing into the reaction path 32C can be reduced.

  Further, in the reactor 310, the flow rate of the exhaust gas G1 flowing from the inflow channel 12 into the reaction channel 132A and the flow rate of the exhaust gas G1 flowing into the reaction channel 132B are smaller than when the flow channel width of the inflow channel is constant. The difference between the flow rate and the flow rate of the exhaust gas G1 flowing into the reaction path 132C can be reduced. Accordingly, the amount of carbon dioxide of the exhaust gas G1 adsorbed in the reaction path 32A, the amount of carbon dioxide of the exhaust gas G1 adsorbed in the reaction path 32B, and the amount of carbon dioxide of the exhaust gas G1 in the reaction path 32C are reduced.

  Further, in the reactor 310, the flow rate of the processing gas G2 flowing from the reaction path 32A to the outflow path 22 and the processing flow flowing from the reaction path 32B to the outflow path 22 are different from the case where the flow path width of the outflow path is constant. The difference between the flow rate of the gas G2 and the flow rate of the processing gas G2 flowing from the reaction path 32C to the outflow path 22 can be reduced. Accordingly, the amount of carbon dioxide of the exhaust gas G1 adsorbed in the reaction path 32A, the amount of carbon dioxide of the exhaust gas G1 adsorbed in the reaction path 32B, and the amount of carbon dioxide of the exhaust gas G1 in the reaction path 32C are reduced. The difference between the adsorbed amount and the adsorbed amount can be reduced.

  The same applies to the flow rate of the processing gas G2 flowing from each reaction path to the outflow path 122 and the flow rate of the processing gas G2 flowing from each reaction path to the outflow path 222.

  Although the present invention has been described in detail with respect to a specific embodiment, the present invention is not limited to such an embodiment, and various other embodiments can be taken within the scope of the present invention. This will be clear to those skilled in the art. For example, in the above embodiment, the exhaust gas G1 flows through the inflow paths 12, 212 from the near side in the apparatus depth direction to the back side, and the processing gas G2 flows through the outflow paths 22, 122, 222 from the near side in the apparatus depth direction. Flowed to the back side. Thus, although the exhaust gas G1 and the processing gas G2 flow in the same direction, the processing gas G2 may flow in the opposite direction to the exhaust gas G1. That is, the processing gas G2 may flow from the back side in the apparatus depth direction to the front side.

  In the above embodiment, the chemical adsorption is described as an example, but physical adsorption may be used.

  In the third and fourth embodiments, two inflow paths 12, 122 are formed and three outflow paths 22, 122, 222 are formed. However, three or more inflow paths may be formed. Four or more outflow channels may be formed.

  In the above embodiment, when viewed from the vertical direction of the apparatus, the reaction path extends in a direction orthogonal to the apparatus depth direction in which the inflow path and the outflow path extend, and connects the inflow path and the outflow path. Was. However, it is only necessary that the reaction path extends in a direction crossing the direction in which the inflow path and the outflow path extend, and connects the inflow path and the outflow path.

  In the above embodiment, the inflow path and the outflow path extend in the same direction. However, the direction in which the inflow path extends and the direction in which the reaction path extends intersect, and the outflow path extends. The direction in which the reaction path extends may intersect with the direction in which the reaction path extends.

  Further, in the above embodiment, the number of reaction paths arranged in the depth direction of the apparatus is three, but may be two or four or more.

  Further, in the above embodiment, the reaction path was formed by a reaction plate formed using zeolite that adsorbs carbon dioxide contained in the exhaust gas G1. However, for example, when the fluid flowing into the reactor is a gas containing water vapor, the reaction path is formed by using silica gel or zeolite formed of silica gel or zeolite that adsorbs water vapor (water) contained in the gas containing water vapor. It is formed of a plate. In addition, for example, when the fluid flowing into the reactor is an exhaust gas, the reaction path is formed by a reaction plate formed using a catalyst that changes the nitrogen acid compound contained in the exhaust gas. In addition, for example, when the fluid flowing into the reactor is an exhaust gas, the reaction path is formed by a reaction plate formed using a catalyst that alters carbon monoxide contained in the exhaust gas.

  Although not particularly described in the above embodiment, the reaction plates may be arranged in a V shape as shown in FIG.
