Detailed Description

The present invention will be described below with reference to embodiments of the invention, but the following embodiments do not limit the invention in the claims. Furthermore, not all combinations of features described in the embodiments are necessary for the solution of the invention.

Fig. 1 is a diagram showing an example of a generating apparatus 100 according to an embodiment of the present invention. The generating apparatus 100 includes a housing unit 10 and an input unit 20. The housing unit generates an alkali solution 30 for treating exhaust gas, and houses the generated alkali solution 30. The housing 10 generates an alkaline solution 30 for treating exhaust gas discharged from a power plant of a ship, a factory, or the like, for example. Treating the exhaust gas means removing Sulfur Oxides (SO) _x ) Nitrogen Oxides (NO) _x ) And the like. The housing portion 10 is, for example, a water tank.

The input unit 20 inputs Mg (magnesium) 22 into the housing unit 10. The input unit 20 is, for example, a hopper. The input portion 20 may be disposed above the housing portion 10. The input unit 20 may input Mg (magnesium) 22 into the housing unit 10 from above the housing unit 10. Mg (magnesium) 22 may be granular. The Mg (magnesium) 22 being in the form of particles may be in a state in which at least a part of the surface of the Mg (magnesium) 22 is curved, or may be in a state in which it is planar. The input unit 20 can input a plurality of granular Mg (magnesium) 22 into the housing unit 10.

The housing 10 has an anode 40 and a cathode 42. The anode 40 is maintained at a predetermined first potential V1. The cathode 42 is maintained at a predetermined second potential V2. The second potential V2 is lower than the first potential V1. Anode 40 and cathode 42 are in contact with alkaline solution 30. Anode 40 and cathode 42 are connected to a power source 90.

The anode 40 is formed of Mg (magnesium). The cathode 42 is formed of a material having a smaller ionization tendency than Mg (magnesium). The cathode 42 is formed of, for example, stainless steel.

The housing portion 10 has a side plate 12 and a bottom plate 14. The alkali solution 30 is contained in the inner space 16 surrounded by the side plates 12 and the bottom plate 14. Above the alkaline solution 30 is the water surface 32.

In the present specification, technical matters are sometimes described using orthogonal coordinate axes of the X axis, the Y axis, and the Z axis. In the present invention, the XY plane is a plane parallel to the plate surface of the base plate 14, and the Z axis direction is a direction perpendicular to the plate surface of the base plate 14. The XY plane may be a horizontal plane and the Z axis direction may be parallel to the gravitational direction. In the present specification, the direction from the anode 40 to the cathode 42 in the XY plane is referred to as the X-axis direction, and the direction orthogonal to the X-axis in the XY plane is referred to as the Y-axis direction.

In the present specification, the water surface 32 side of the alkaline solution 30 in the Z-axis direction is referred to as "upper", and the bottom plate 14 side is referred to as "lower". In the present specification, the top view means that the housing 10 is viewed from the water surface 32 toward the bottom plate 14 in the Z-axis direction.

The bottom plate 14 is disposed below the alkaline solution 30. In fig. 1, the side plate 12 on the anode 40 side is the side plate 12-1 and the side plate 12 on the cathode 42 side is the side plate 12-2, respectively, but the side plate 12 may be one side plate 12 surrounding the internal space 16 in a plan view.

The predetermined area in the housing portion 10 is set as the input area 24. The input region 24 is the region between the anode 40 and the cathode 42. The input unit 20 inputs Mg (magnesium) 22 into the input region 24. The input region 24 may be a predetermined region in the XY plane in a plan view, and may be a predetermined region upward from the bottom plate 14 in the internal space 16 in the Z axis direction.

The housing portion 10 may have a carry-in port 80 and a carry-out port 82. The liquid 130 for generating the alkali solution 30 can be carried into the housing portion 10 through the carrying-in port 80. The liquid 130 is, for example, H ₂ O (water). Liquid 130 is H ₂ In the case where O (water) and anode 40 are formed of Mg (magnesium), H ₂ The electrolytic decomposition reaction formula of O (water) is represented by the following

chemical formulas

1 and 2.

[ chemical formula 1]

Mg→Mg ²⁺ +2e ^-

[ chemical formula 2]

2H ₂ O+2e ^- →H ₂ +2OH ^-

Chemical formula 1 and chemical formula 2 are chemical reactions at the anode 40 and the cathode 42, respectively. Alkali ions (in this case OH) are generated at the cathode 42 ^- (hydroxide ion)). Thus, the alkaline solution 30 can treat exhaust gas discharged from power plants of ships, factories, and the like. The alkali solution can be carried out of the housing 10 through the carrying-out port 82. In addition, H generated by chemical formula 2 ₂ The (hydrogen) may be discharged to the outside of the production apparatus 100 or may be reused in a fuel cell or the like.

In the generating apparatus 100, the input unit 20 inputs Mg (magnesium) 22 into the input region 24 of the housing unit 10. The Mg (magnesium) 22 charged into the charging region 24 shows the chemical reaction represented by chemical formula 1 described above, similarly to the anode 40. Therefore, in the production apparatus 100, the alkali solution 30 is easily and rapidly produced as compared with the case where Mg (magnesium) 22 is not added.

Since Mg (magnesium) 22 fed into the feeding region 24 shows the chemical reaction represented by chemical formula 1, it tends to be small as the chemical reaction time elapses. Since the generating apparatus 100 includes the input unit 20, when the Mg (magnesium) 22 to be input into the input region 24 is small, the input unit 20 can easily input a new Mg (magnesium) 22 into the input region 24. Therefore, in the production apparatus 100, the chemical reactions represented by chemical formula 1 and chemical formula 2 described above are likely to continue, as compared with the case where the input unit 20 is not provided.

In the case where electric power is not supplied from the power source to the anode 40 and the cathode 42, chemical reactions represented by chemical formula 1 and chemical formula 2 are not likely to occur on both the anode 40 and the cathode 42. In the case where the chemical reactions represented by

chemical formulas

1 and 2 do not occur on both the anode 40 and the cathode 42, passivation of the surface of Mg (magnesium) 22 sometimes occurs. When the surface of Mg (magnesium) 22 is passivated, the potential difference V' between the first potential V1 (potential of anode 40) and the second potential V2 (potential of cathode 42) can be maintained at a potential difference larger than the potential difference V when the surface of Mg (magnesium) 22 is not passivated by power supply 90. The potential difference V' is, for example, 1.2 times the potential difference V.

When the potential difference between the first potential V1 (potential of the anode 40) and the second potential V2 (potential of the cathode 42) is maintained at the potential difference V' for a predetermined time, the passivated portion of the Mg (magnesium) 22 surface peels off. Therefore, the potential difference between the first potential V1 (the potential of the anode 40) and the second potential V2 (the potential of the cathode 42) can be returned to the potential difference V. The predetermined time for which the potential difference between the first potential V1 and the second potential V2 is maintained at the potential difference V' is, for example, 10 minutes.

When electric power is continuously supplied from the power supply 90 to the anode 40 and the cathode 42, the surface of the Mg (magnesium) 22 is less likely to be passivated. Accordingly, it is preferable to continuously supply electric power from the power supply 90 to the anode 40 and the cathode 42.

The width of the particle diameter of Mg (magnesium) 22 is set to be width Dm. In the case where the granular Mg (magnesium) 22 is spherical, the width Dm may be the diameter of the spherical Mg (magnesium) 22. In the case where the granular Mg (magnesium) 22 is not spherical, the width Dm may be the maximum width of the particle diameter of the granular Mg (magnesium) 22. The width Dm is, for example, 3.0mm or more and less than 10.00mm.

The receptacle 10 may have 1 or more first screens 50. In this example, the housing portion 10 has 2 first screens 50 (first screen 50-1 and first screen 50-2). In this example, the first screen 50-1 is disposed on the anode 40 side in the X-axis direction, and the first screen 50-2 is disposed on the cathode 42 side in the X-axis direction.

The first screen 50 may have a plate shape having a plate surface parallel to the YZ plane. The first screen 50 may be provided with openings (described later) penetrating the plate-like plate surface in the X-axis direction. A plurality of such openings may be provided in the first screen 50. The alkaline solution 30 is able to pass through the first screen 50.Mg (magnesium) 22 cannot pass through the first screen 50.

The first screen 50 may be non-conductive. Nonconductors may be referred to as having a conductivity of 10 ^-6 S/m or less. Nonconductors may also refer to conductors of conductivity 10 ^-12 A material of a multiple or less. The conductor may be referred to as having a conductivity of 10 ⁶ S/m or more. The first screen 50 of this example is, for example, resin or the like.

Anode 40 and drop zone 24 may be separated by a first screen 50 (in this case, first screen 50-1). Thereby, the anode 40 and the Mg (magnesium) 22 put into the input region 24 are easily isolated. Thus, the anode 40 and Mg (magnesium) 22 charged into the charging region 24 easily show the chemical reaction expressed by chemical formula 1 described above in addition. Accordingly, the alkali solution 30 is easily and rapidly generated as compared with the case where the anode 40 and the throw-in area 24 are not isolated by the first screen 50.

The cathode 42 and the input area 24 may be separated by another first screen 50 (in this case, first screen 50-2). Thereby, the cathode 42 and the Mg (magnesium) 22 put into the input region 24 are easily isolated. Thus, the cathode 42 and the Mg (magnesium) 22 put into the input region 24 are less likely to be short-circuited.

The input area 24 may be an area between the first screen 50-1 and the first screen 50-2 in the X-axis direction. In the X-axis direction, the first screen 50-1 may be disposed at an end position on the anode 40 side of the input region 24, and the first screen 50-2 may be disposed at an end position on the cathode 42 side of the input region 24.

The first screen 50 may be disposed between the carry-in port 80 and the carry-out port 82 in the flow path of the alkali solution 30. In this example, the flow path of the alkaline solution 30 is in the direction from the cathode 42 to the anode 40. The first screen 50 is disposed between the carry-in port 80 and the carry-out port 82 in the flow path, and the alkali solution 30 produced by the reaction represented by chemical formula 1 and chemical formula 2 is easily carried out from the housing portion 10 through the carry-out port 82.

Fig. 2 is a view showing an example of the first screen 50. Fig. 2 is a view of the first screen 50 shown in fig. 1 when viewed in a direction from the input area 24 toward the anode 40. The first screen 50 may be a plate-like member having openings 51 provided in a plate surface. In this example, the plate surface is a YZ surface. The opening 51 penetrates the plate-like member in the X-axis direction. The first screen 50 of this example has a bottom edge 53. The bottom edge 53 may be in contact with the bottom plate 14 (see fig. 1) of the housing portion 10.

The width in the YZ plane of the opening 51 is set to the width Dp. In the case where the opening 51 is circular, the width Dp may be the diameter of the circular opening 51. In the case where the opening 51 is not circular, the width Dp may be the maximum width of the opening 51. The width Dp is smaller than the width Dm of the particle diameter of Mg (magnesium) 22. Thus, mg (magnesium) 22 cannot pass through the first screen 50.

The first screen 50 may have a plurality of openings 51 disposed therein. In this example, the width Dp of each of the plurality of openings 51 is equal. The first screen 50 of this example is formed by providing the plate-like member with the openings 51, but the first screen 50 may be formed by knitting linear threads into a mesh shape.

Fig. 3 is a diagram showing a generating apparatus 200 of a comparative example. The generating apparatus 200 does not include the input unit 20 and the first screen 50. The generating device 200 includes an intermediate electrode 41 made of Mg (magnesium). The generating apparatus 200 differs from the generating apparatus 100 in these respects. In the generating device 200, 3 intermediate electrodes 41 (intermediate electrodes 41-1 to 41-3) are arranged between the anode 40 and the cathode 42 on the X-axis. The intermediate electrode 41 is not connected to the power supply 90.

On the anode 40 side of the intermediate electrode 41, the chemical reaction represented by chemical formula 2 described above occurs. On the cathode 42 side of the intermediate electrode 41, the chemical reaction represented by chemical formula 1 described above occurs. Therefore, the intermediate electrode 41 tends to become smaller as the chemical reaction time passes. Since the generating apparatus 200 does not include the input unit 20, when the intermediate electrode 41 is small, new Mg (magnesium) cannot be input into the internal space 16. Therefore, in the generating apparatus 200, the chemical reactions represented by chemical formula 1 and chemical formula 2 described above are not easily continued.

Fig. 4 is a diagram showing a generating apparatus 300 of a comparative example. In the generating apparatus 300, the housing portion 10 has 3 anodes 40 (anodes 40-1 to 40-3) and 2 cathodes 42 (cathodes 42-1 and 42-2). The 3 anodes 40 and the 2 cathodes 42 are arranged in the order of the anode 40-1, the cathode 42-1, the anode 40-3, the cathode 42-2, and the anode 40-2 in the X-axis direction.

Fig. 5 is a graph showing the alkali generation rates of the generator 200 and the generator 300. The alkalinity in fig. 5 may refer to the alkali ion concentration of the alkali solution 30. The basicities of the generating device 200 and the generating device 300 increase with the lapse of time.

The base generation speed of the generating device 200 and the base generation speed of the generating device 300 are almost equal. That is, the base generation rate of the generator 200 is almost equal to the base generation rate of the generator 300, regardless of whether the intermediate electrode 41 (see fig. 3) in the generator 200 is connected to the power supply 90. Therefore, mg (magnesium) 22 (see fig. 1) in production apparatus 100 is not connected to power supply 90, but production apparatus 100 can maintain the same alkali production rate as production apparatus 300.

Fig. 6 is a diagram showing an example of the generating apparatus 100 shown in fig. 1 in a plan view. However, the input unit 20 and the power supply 90 shown in fig. 1 are omitted in fig. 6. The inner space 16 is surrounded by the side plates 12 in a plan view. Anode 40 and cathode 42 may be plate-shaped. In this example, the plate-like anode 40 has a surface 45 facing the cathode 42, and the plate-like cathode 42 has a surface 43 facing the anode 40. In this example, the

surfaces

45 and 43 are parallel to the YZ plane. The alkaline solution 30 may be sandwiched between the

faces

45 and 43 in the X-axis direction.

The first screen 50 may have a plate shape having a plate surface parallel to the YZ plane. In fig. 6, the ranges of the input regions 24 in the X-axis direction and the Y-axis direction are indicated by double arrows, respectively.

The first screen 50 may extend in the Y-axis direction from one side plate 12 to the other side plate 12 in the Y-axis direction. In this example, anode 40 and input area 24 are separated by a first screen 50-1, and cathode 42 and input area 24 are separated by a first screen 50-2.

Fig. 7 is a view showing another example of the generating apparatus 100 shown in fig. 1 in a plan view. In the production apparatus 100 of the present example, the input area 24 is surrounded by the first screen 50. The generating apparatus 100 of the present example is different from the generating apparatus shown in fig. 6 in this respect.

One end of the anode 40 in the Y-axis direction is set as an end Ep1, and the other end is set as an end Ep2. One end of the cathode 42 in the Y-axis direction is set as an end En1, and the other end is set as an end En2. The position of the end Ep1 and the position of the end En1 may be the same, and the position of the end Ep2 and the position of the end En2 may be different in the Y-axis direction.

In the production apparatus 100 of the present example, the input region 24 is surrounded by the first screen 50, so that Mg (magnesium) 22 input through the input portion 20 is easily disposed between one end Ep1 and the other end Ep2 of the anode 40 and between one end En1 and the other end En2 of the cathode 42.

Fig. 8 is a diagram showing another example of the generating apparatus 100 according to the embodiment of the present invention. In this example, the housing 10 has a second screen 52. The generating apparatus 100 of the present example is different from the generating apparatus 100 shown in fig. 1 in this respect. The second screen 52 of this example is disposed between the anode 40 and the first screen 50-1 in the direction from the anode 40 to the cathode 42 (X-axis direction).

The second screen 52 may have a plate shape having a plate surface parallel to the YZ plane. The second screen 52 may be provided with openings penetrating the plate-like plate surface in the X-axis direction. A plurality of such openings may be provided in the second screen 52. The width of the openings may be equal to the width Dp (see fig. 2) of the openings 51 of the first screen 50. The alkaline solution 30 is able to pass through the second screen 52.Mg (magnesium) 22 cannot pass through the second screen 52.

The second screen 52 may be non-conductive. The second screen 52 may be formed of the same substance as the first screen 50.

The predetermined area in the housing portion 10, that is, another input area different from the input area 24 is set as an input area 25. The drop zone 25 is the zone between the anode 40 and the second screen 52. In this example, the input unit 20 inputs Mg (magnesium) 22 into the input region 24 and the input region 25. The input region 25 may be a predetermined region in the XY plane in a plan view, or may be a predetermined region upward from the bottom plate 14 in the internal space 16 in the Z axis direction.

In this example, since Mg (magnesium) 22 is charged into the charging region 25 between the anode 40 and the second screen 52 by the charging portion 20, at least a part of the Mg (magnesium) 22 charged into the charging region 25 is likely to contact with the anode 40. Since the anode 40 is formed of Mg (magnesium), the anode 40 is liable to become smaller as the chemical reaction time passes by the chemical reaction represented by chemical formula 1 described above. In this example, since at least a part of Mg (magnesium) 22 charged into the charging region 25 is in contact with the anode 40, the chemical reaction represented by chemical formula 1 and chemical formula 2 described above is likely to proceed more easily than in the case where Mg (magnesium) 22 is not charged into the charging region 25.

Fig. 9 is a diagram showing an example of the generating apparatus 100 shown in fig. 8 in a plan view. The second screen 52 may have a plate shape having a plate surface parallel to the YZ plane. In fig. 9, the ranges of the input regions 25 in the X-axis direction and the Y-axis direction are indicated by double arrows, respectively. In this example, from the end Ep1 to the end Ep2 in the Y-axis direction is a range of the input region 25.

The second screen 52 may extend in the Y-axis direction from one side plate 12 to the other side plate 12 in the Y-axis direction. In this example, anode 40 and first screen 50-1 are separated by second screen 52. .

Fig. 10 is a diagram showing another example of the generating apparatus 100 according to the embodiment of the present invention. The receptacle 10 may have a plurality of second screens 52. In this example, the housing portion 10 has 2 second screens 52 (second screen 52-1 and second screen 52-2). The generating apparatus 100 of the present example is different from the generating apparatus 100 shown in fig. 8 in this respect.

In this example, the second screen 52-1 is disposed closer to the cathode 42 than the anode 40 in the direction from the anode 40 to the cathode 42 (X-axis direction). In this example, the second screen 52-1 is disposed between the anode 40 and the first screen 50-1 in this direction (X-axis direction).

In this example, the second screen 52-2 is disposed farther from the cathode 42 than the anode 40 in the direction from the anode 40 to the cathode 42 (X-axis direction). In this example, the second screen 52-2 is disposed between the side plate 12-1 and the anode 40 in this direction (X-axis direction).

Fig. 11 is an enlarged view of anode 40, second screen 52-1 and vicinity of second screen 52-2 in fig. 10. However, the carry-out port 82 is omitted in fig. 11. One end of the anode 40 in the X-axis direction is set as an end Ep3, and the other end is set as an end Ep4. The end Ep3 is an end of the anode 40 on the side plate 12-1 side in the X-axis direction. The end Ep4 is the end of the anode 40 on the cathode 42 side in the X-axis direction.

The width between the anode 40 and the second screen 52-2 in the direction from the anode 40 to the cathode 42 (X-axis direction in this example) is set to a width Wx1. In this example, the width Wx1 is the width between the second screen 52-2 and the end Ep3 in the X-axis direction. The width between the anode 40 and the second screen 52-1 in the direction from the anode 40 to the cathode 42 (X-axis direction in this example) is set to a width Wx2. In this example, the width Wx2 is the width between the end Ep4 in the X-axis direction and the second screen 52-1. The width Wx1 may be a maximum of the width between the second screen 52-2 and the end Ep3 and the width Wx2 may be a minimum of the width between the end Ep4 and the second screen 52-1 in the Z-axis direction from the bottom plate 14 to the water surface 32.

In this example, width Wx2 is larger than width Dm, and width Wx1 is smaller than width Dm. The chemical reactions represented by chemical formula 1 and chemical formula 2 described above are performed between the anode 40 and the cathode 42 in the X-axis direction. Therefore, mg (magnesium) 22 is preferably disposed between anode 40 and second screen 52-1 in the direction from anode 40 to cathode 42. In this example, since the width Wx2 is larger than the width Dm and the width Wx1 is smaller than the width Dm, the Mg (magnesium) 22 fed from the feeding section 20 is not accommodated between the second screen 52-2 and the end Ep3, but is easily accommodated between the end Ep4 and the second screen 52-1.

Fig. 12 is a diagram showing an example of the generating apparatus 100 shown in fig. 10 in a plan view. The second screen 52-1 and the second screen 52-2 may extend in the Y-axis direction from one side plate 12 to the other side plate 12 in the Y-axis direction.

Fig. 13 is a view showing another example of the generating apparatus 100 shown in fig. 10 in a plan view. In this example, the anode 40 is surrounded by a second screen 52 in a top view. The generating apparatus 100 of the present example is different from the generating apparatus 100 shown in fig. 12 in this respect.

In this example, the second screen 52 disposed closer to the side plate 12-1 than the anode 40 among the 1 second screens 52 is the second screen 52-1, and the second screen 52 disposed closer to the cathode 42 than the anode 40 is the second screen 52-2. The positions of the second screen 52-1 and the second screen 52-2 in the X-axis direction are the same as those of the example shown in fig. 10.

In the housing portion 10, the area surrounded by the second screen 52 is defined as an area 28. The region 28 may be the same as the input region 25, or may include the input region 25. In this example, the region 28 is the same as the input region 25.

The input unit 20 (see fig. 8) may input Mg (magnesium) 22 into the region 28. As described above, in this example, since the width Wx2 is larger than the width Dm (see fig. 11) and the width Wx1 is smaller than the width Dm (see fig. 11), the Mg (magnesium) 22 fed from the feeding section 20 is not accommodated between the second screen 52-2 and the end Ep3 (see fig. 11), but is easily accommodated between the end Ep4 (see fig. 11) and the second screen 52-1. Thus, mg (magnesium) 22 charged into the region 28 easily promotes the chemical reactions represented by chemical formula 1 and chemical formula 2 described above.

In the housing portion 10, a region surrounded by the first screen 50 is defined as a region 27. The region 27 may be the same as the input region 24, or may include the input region 24. In this example, the region 27 is the same as the input region 24.

The area 28 surrounded by the second screen 52 may be smaller than the area 27 surrounded by the first screen 50 in a top view. The area of the region 28 surrounded by the second screen 52 in a plan view may be smaller than the area of the region 27 surrounded by the first screen 50 in a plan view. Mg (magnesium) 22 is preferably dispersed in region 28.

Mg (magnesium) 22 is dispersed in region 28, and thus facilitates the chemical reactions represented by chemical formula 1 and chemical formula 2. Mg (magnesium) 22 is preferably near anode 40 in region 27. Mg (magnesium) 22 facilitates the chemical reactions represented by chemical formula 1 and chemical formula 2 described above by approaching anode 40 in region 27. Therefore, in a top view, the area 28 surrounded by the second screen 52 is preferably smaller than the area 27 surrounded by the first screen 50.

Fig. 14 is another enlarged view of the vicinity of the anode 40, the second screen 52 and the first screen 50 in fig. 10. However, the carry-out port 82 is omitted in fig. 14. In this example, mg (magnesium) 22 put into the region 27 surrounded by the first screen 50 is referred to as Mg (magnesium) 22-1, and Mg (magnesium) 22 put into the region 28 surrounded by the second screen 52 is referred to as Mg (magnesium) 22-2.

The width of the particle diameter of Mg (magnesium) 22-2 is the width Dm (see fig. 11). In this example, the width of the particle diameter of Mg (magnesium) 22-1 is defined as the width Dm'. The width Dm may be smaller than the width Dm'. As described above, mg (magnesium) 22-2 is preferably in contact with anode 40. The smaller the width Dm, the more easily the contact area of Mg (magnesium) 22-2 with the anode 40 becomes.

Fig. 15 is a view showing another example of the generating apparatus 100 shown in fig. 10 in a plan view. In this example, the face 45 of the anode 40 has a recess 44. In this example, the generating apparatus 100 is different from the generating apparatus 100 shown in fig. 12 in this respect. In this example, the concave portion 44 is recessed in a direction away from the cathode 42 in the X-axis direction (a direction from the cathode 42 to the anode 40). In fig. 15, mg (magnesium) 22 put into the input region 25 shown in fig. 12 is omitted.

Mg (magnesium) 22 may be disposed in the recess 44. In this example, since the concave portion 44 is recessed in a direction away from the cathode 42, the Mg (magnesium) 22 put into the input region 25 is easily arranged between the end portion Ep1 and the end portion Ep2 in the Y-axis direction. In fig. 15, the concave portion 44 is provided from the end portion Ep1 to the end portion Ep2 in the Y-axis direction, but the concave portion 44 may be provided at a part of the surface 45 in the Y-axis direction, and the remaining part of the surface 45 in the Y-axis direction is a plate surface parallel to the YZ-plane.

Fig. 16 is a diagram showing another example of the generating apparatus 100 according to the embodiment of the present invention. In the generating apparatus 100 of the present embodiment, the housing portion 10 further includes an intermediate screen 54. The generating apparatus 100 of the present example is different from the generating apparatus 100 shown in fig. 10 in this respect.

The intermediate screen 54 may be disposed between one first screen 50 (first screen 50-1 in this example) and the other first screen (first screen 50-2 in this example) in a direction from the anode 40 toward the cathode 42 (X-axis direction in this example). The intermediate screen 54 isolates at least a portion of the drop zone 24 from the anode 40.

The intermediate screen 54 may be disposed inside the region 27 (see fig. 13) surrounded by the first screen 50. The receptacle 10 may have a plurality of intermediate screens 54. In this example, the housing portion 10 has 3 intermediate screens 54 (intermediate screen 54-1 to intermediate screen 54-3) in the X-axis direction.

The intermediate screen 54-1 to the intermediate screen 54-3 may have a plate shape having a plate surface parallel to the YZ plane. The intermediate screen 54-1 to the intermediate screen 54-3 may be provided with openings penetrating the plate surface in the X-axis direction. A plurality of such openings may be provided in the intermediate screen 54-1 to the intermediate screen 54-3. The width of the openings may be equal to the width Dp (see fig. 2) of the openings 51 of the first screen 50. The alkali solution 30 can pass through the intermediate screen 54-1 to the intermediate screen 54-3. In this example, the Mg (magnesium) 22 cannot pass through the intermediate screen 54-1 to the intermediate screen 54-3.

Fig. 17 is a diagram showing another example of the generating apparatus 100 according to the embodiment of the present invention. Fig. 17 is a top view of the generating device 100. The plurality of intermediate screens 54 may be arranged in a direction from the anode 40 to the cathode 42 (in this example, in the X-axis direction) or in a direction intersecting the direction from the anode 40 to the cathode 42 (in this example, in the Y-axis direction). In this example, the intermediate screens 54-1 to 54-3 are arranged in the X-axis direction, and the intermediate screens 54-4 to 54-6 are arranged in the Y-axis direction. The intermediate screens 54-4 to 54-6 may be in contact with the bottom plate 14 as the intermediate screens 54-1 to 54-3.

The intermediate screen 54-4 to the intermediate screen 54-6 may be disposed between the side plates 12 facing each other in the Y-axis direction. Intermediate screen 54-4 through intermediate screen 54-6 may extend in the X-axis direction from first screen 50-1 to first screen 50-2.

The intermediate screen 54-4 to the intermediate screen 54-6 may have a plate shape having a plate surface parallel to the XZ plane. The intermediate screen 54-4 to the intermediate screen 54-6 may be provided with openings penetrating the plate surface in the Y-axis direction. A plurality of such openings may be provided in intermediate screen 54-4 through intermediate screen 54-6. The width of the openings may be equal to the width Dp (see fig. 2) of the openings 51 of the first screen 50. The alkali solution 30 can pass through the intermediate screen 54-4 to the intermediate screen 54-6. In this example, the Mg (magnesium) 22 cannot pass through the intermediate screen 54-4 to the intermediate screen 54-6.

In this example, since the housing portion 10 has the intermediate screen 54, the Mg (magnesium) 22 charged into the charging area 24 is more easily dispersed in the charging area 24 than in the case where the housing portion 10 does not have the intermediate screen 54. Therefore, the chemical reaction represented by chemical formula 1 and chemical formula 2 described above is more easily promoted than in the case where the housing portion 10 does not have the intermediate screen 54.

Fig. 18 is a view showing another example of the first screen 50. In this example, the opening 51 decreases as it moves upward from the bottom plate 14 (see fig. 1). The first screen 50 of the present example differs from the first screen 50 shown in fig. 2 in this respect. In this example, the diameter of the opening 51 on the bottom side 53 side is the width Dp, and the diameter of the opening 51 disposed farthest from the bottom side 53 in the Z-axis direction is the width Dp'. The width Dp' is smaller than the width Dp.

As described above, mg (magnesium) 22 charged into the charging region 24 shows the chemical reaction represented by chemical formula 1 described above. Therefore, the Mg (magnesium) 22 tends to gradually decrease with the passage of the chemical reaction time. The reduced Mg (magnesium) 22 may float in the alkaline solution 30 (see fig. 1) in the input region 24. Therefore, when the width Dm (see fig. 1 and 11) of the Mg (magnesium) 22 is smaller than the width Dp of the opening 51, the Mg (magnesium) 22 may pass through the opening 51 above the inside of the alkaline solution 30.

In this example, the opening 51 of the first screen 50 becomes smaller as it moves upward from the bottom plate 14 (see fig. 1). Therefore, mg (magnesium) 22 that has become small due to chemical reaction is not easy to pass through the opening 51 above the inside of the alkali solution 30.

Fig. 19 is a diagram showing another example of the generating apparatus 100 according to the embodiment of the present invention. The generating apparatus 100 of the present example further includes Mg (magnesium) moving means 122. In this example, the housing portion 10 further has a connection portion 70. The generating apparatus 100 of the present example differs from the generating apparatus 100 shown in fig. 10 in these respects.

The connection 70 connects the area 27 surrounded by the first screen 50 and the area 28 surrounded by the second screen 52. The connection 70 may be a tubular member having an inner diameter that enables Mg (magnesium) 22-1 in the region 27 to pass through. The Mg (magnesium) 22-1 in the region 27 is moved into the region 28 by the Mg moving unit 122 through the connection 70. Magnesium moving unit 122 may be a pump that generates a flow of alkaline solution 30 in a direction from zone 27 to zone 28.

As described above, the width Dm (see fig. 11) of the particle diameter of Mg (magnesium) 22-2 in the region 28 may be smaller than the width Dm' (see fig. 11) of the particle diameter of Mg (magnesium) 22-1 in the region 27. As described above, mg (magnesium) 22 charged into the charging region 24 is liable to be reduced with the lapse of time by the chemical reaction represented by chemical formula 1. In the generating apparatus 100 of the present example, the magnesium moving unit 122 moves the Mg (magnesium) 22-1 having a particle diameter smaller than the width Dm' in the region 27 to the region 28. Therefore, the generating apparatus 100 of the present example can effectively use Mg (magnesium) 22-1 having a smaller width than the width Dm' of the particle size in the region 28. A new Mg (magnesium) 22-1 having a particle diameter of width Dm' can be fed into the feeding region 27 through the feeding portion 20.

The connection portion 70 may be disposed above 1/2 of the height from the bottom plate 14 to the water surface 32, or above 1/4. Mg (magnesium) 22-1 having a smaller width than width Dm' tends to move inside alkaline solution 30 to a level of 1/2 of the height from bottom plate 14 to water surface 32. Accordingly, the connection 70 may be disposed above 1/2 of the height from the floor 14 to the water surface 32.

In addition, mg (magnesium) 22-1 in region 27 can be moved to region 28 by the flow of alkali solution 30 from carry-in port 80 to carry-out port 82. In this example, the first screen 50 is disposed between the carry-in port 80 and the carry-out port 82 in the flow path of the alkali solution 30, so that the Mg (magnesium) 22-1 can be moved to the region 28 by the flow of the alkali solution 30. In the case where Mg (magnesium) 22-1 in the region 27 moves to the region 28 by the flow of the alkali solution 30, the production apparatus 100 may not include the magnesium moving means 122.

Fig. 20 is a diagram showing another example of the generating apparatus 100 according to the embodiment of the present invention. The generating apparatus 100 of the present example is different from the generating apparatus 100 shown in fig. 19 in that it further includes a stirring section 72. The stirring section 72 stirs the alkali solution 30. The stirring section 72 may be provided in the input region 24. The stirring section 72 is, for example, a propeller. The stirring section 72 may be driven by a motor.

Since the production apparatus 100 of this example includes the stirring section 72, mg (magnesium) 22 is easily dispersed in the alkali solution 30. Therefore, the production apparatus 100 of this example facilitates the chemical reactions represented by chemical formula 1 and chemical formula 2 described above.

Fig. 21 is a diagram showing an example of a generating apparatus 400 according to an embodiment of the present invention. The generating apparatus 400 is different from the generating apparatus 100 shown in fig. 10 in that the anode 40 is not provided. In the production apparatus 400, the housing portion 10 includes the cathode 42 in contact with the alkali solution 30 and the second screen 52 in contact with the alkali solution 30. In the production apparatus 400, the input unit 20 inputs Mg (magnesium) 22 into the input region 24 and the region 28 surrounded by the second screen 52 in the housing unit 10. The input area 24 is the area between the area 27 surrounded by the second screen 52 and the cathode 42.

The Mg (magnesium) 22 charged into the charging region 24 is referred to as Mg (magnesium) 22-1. The Mg (magnesium) 22 charged into the region 28 is referred to as Mg (magnesium) 22-2.Mg (magnesium) 22-2 is maintained at a predetermined first potential V1. The cathode 42 is maintained at a predetermined second potential V2. The second potential V2 is lower than the first potential V1.

Mg (magnesium) 22-2 and cathode 42 are in contact with alkaline solution 30. Mg (magnesium) 22-2 and cathode 42 are connected to a power source 90.

The second screen 52 of this example is a conductor. At least a portion of Mg (magnesium) 22-2 fed into the region 28 surrounded by the second screen 52 is in contact with the second screen 52 of the conductor. The second screen 52 may be maintained at the first potential V1.Mg (magnesium) 22-2 may be maintained at a first potential V1 by second screen 52 being maintained at a first potential V1. As described above, the conductor may refer to a conductivity of 10 ⁶ S/m or more.

Fig. 22 is a diagram showing an example of the generating device 400 shown in fig. 21 in a plan view. The region 28 surrounded by the second screen 52 is disposed away from the cathode 42 in a plan view of the housing portion 10. In the production apparatus 400, the chemical reaction of chemical formula 1 described above is shown by Mg (magnesium) 22-1 charged into the charging region 24 and Mg (magnesium) 22-2 charged into the region 28. Thereby, an alkaline solution 30 is produced.

Fig. 23 is a diagram showing another example of the generating apparatus 100 according to the embodiment of the present invention. The generating apparatus 100 of this example is different from the generating apparatus 100 shown in fig. 1 in that it further includes a current measuring unit 97 and an input control unit 99. The input control unit 99 controls the timing of the input unit 20 to input Mg (magnesium) 22 into the input region 24. In this example, the power supply 90 is a constant voltage power supply.

The current measuring unit 97 measures the current flowing between the anode 40 and the cathode 42. This current is set to current Inp. The current measuring unit 97 is, for example, a ammeter. The input control unit 99 controls the timing of the input unit 20 to input Mg (magnesium) 22 into the input region 24 based on the current Inp measured by the current measuring unit 97.

The chemical reactions represented by chemical formula 1 and chemical formula 2 described above occur at the anode 40 and the cathode 42. Mg (magnesium) 22 charged into the charging region 24 is chemically reacted by chemical formula 1 to form magnesium ions (Mg ²⁺ ) And dissolves out into the alkaline solution 30. Therefore, as the time of the chemical reaction represented by chemical formula 1 and chemical formula 2 passes, the current flowing between the anode 40 and the cathode 42 is liable to become small. In this example, the input control unit 99 controls the timing of inputting Mg (magnesium) 22 into the input region 24 based on the current Inp, so that the chemical reactions represented by chemical formula 1 and chemical formula 2 can be easily controlled.

The input control unit 99 may control the input unit 20 to input Mg (magnesium) 22 to the input region 24 when the current Inp is smaller than a predetermined threshold current Ith. Thereby, the chemical reactions represented by chemical formula 1 and chemical formula 2 described above are easily continued.

Fig. 24 is a diagram showing another example of the generating apparatus 100 according to the embodiment of the present invention. The generating apparatus 100 of the present example is different from the generating apparatus 100 shown in fig. 1 in that it further includes a voltage measuring unit 98 and an input control unit 99. In the generating device 100 of this example, instead of the power supply 90 shown in fig. 1, a current source 92 is connected to the anode 40 and the cathode 42. In this example, the current source 92 is a constant current source.

The voltage measuring unit 98 measures the voltage between the anode 40 and the cathode 42. This voltage is set to a voltage Vnp. The voltage measuring unit 98 is, for example, a voltmeter. The input control unit 99 controls the timing of the input unit 20 to input Mg (magnesium) 22 into the input region 24 based on the voltage Vnp measured by the voltage measurement unit 98.

As the time of the chemical reaction represented by chemical formula 1 and chemical formula 2 described above passes, the voltage flowing between the anode 40 and the cathode 42 is liable to become small. In this example, the input control unit 99 controls the timing of inputting Mg (magnesium) 22 into the input region 24 based on the voltage Vnp, so that the chemical reactions represented by

chemical formulas

1 and 2 can be easily controlled.

The input control unit 99 may control the input unit 20 to input Mg (magnesium) 22 to the input region 24 when the voltage Vnp is smaller than the predetermined threshold current Vth. Thereby, the chemical reactions represented by chemical formula 1 and chemical formula 2 described above are easily continued.

Fig. 25 is a diagram showing an example of an exhaust gas treatment system 500 according to an embodiment of the present invention. The exhaust gas treatment system 500 includes an exhaust gas treatment device 110, a

generation device

100 or 400, and a mixing unit 140. In fig. 25, the range of the exhaust treatment system 500 is indicated by a dash-dot line.

The exhaust gas treatment device 110 is, for example, a scrubber for a ship. Exhaust gas 152 discharged from power plant 150 is introduced into exhaust gas treatment device 110. The power plant 150 is, for example, an engine. The exhaust gas 152 contains sulfur oxides (SO _x ) Nitrogen Oxides (NO) _x ) And the like.

The exhaust treatment device 110 treats the exhaust 152. The exhaust gas treatment device 110 discharges the wastewater 132 after the exhaust gas 152 is treated. The waste water 132 is liable to contain the above-mentioned harmful substances. Thus, the wastewater 132 becomes acidic easily.

The mixing section 140 mixes the wastewater 132 discharged from the exhaust gas treatment device 110 with the alkali solution 30 generated by the generating device 100 or the generating device 400. The mixing section 140 mixes the wastewater 132 with the alkali solution 30 to generate a liquid 160.

The mixing section 140 mixes the wastewater 132 with the alkali solution 30, so that a liquid 160 having a pH greater than that of the wastewater 132 can be produced. Liquid 160 may be introduced into exhaust treatment device 110. In the exhaust treatment device 110, the exhaust 152 may be treated with a liquid 160.
