[Figure 3] FIG. 3 is an explanatory diagram of the assembly of the desulfurizer. [Figure 4] FIG. 4 is an explanatory diagram of a desulfurizer according to a reference embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0008] (Findings that formed the basis of this disclosure) FIG. 4 is an explanatory diagram of a desulfurizer 700 according to a reference embodiment studied by the present inventors.

[0009] 4(a) shows the desulfurizer 700 placed vertically. As shown in FIG. 4(a), the desulfurizer 700 includes a desulfurizing agent 761, a desulfurizing agent 762, a tube 750, a partition 770, a partition 771, and a partition 772. The tube 750 includes a side wall 750w and an internal region 750h. The side wall 750w defines the internal region 750h.

[0010] The cylinder 750 extends in a direction 780. In the inner region 750h, a gas flow 790 is formed in the direction 780. In the inner region 750h, a partition 772, a desulfurization agent 762, a partition 771, a desulfurization agent 761, and a partition 770 are arranged in this order along the direction 780.

[0011] In the vertical installation shown in (a) of Figure 4, the direction 780 is parallel to the vertical direction. The partition 772, the desulfurization agent 762, the partition 771, the desulfurization agent 761, and the partition 770 are arranged in this order from bottom to top in the vertical direction. This also applies to (c) of Figure 4.

[0012] 4(a), a gap 711 is generated between the partition 771 and the partition 770 on the vertically upper side of the desulfurization agent 761. Furthermore, a gap 712 is generated between the partition 772 and the partition 771 on the vertically upper side of the desulfurization agent 762. The generation of the gaps 711 and 712 is due to variations in the filling of the desulfurization agents 761 and 762 into the tube 750, dimensional tolerances of the components of the desulfurizer 700, etc.

[0013] 4(b) shows the desulfurizer 700 placed horizontally. In the horizontal placement shown in FIG. 4(b), the direction 780 is parallel to the horizontal direction. The partition 772, the desulfurizing agent 762, the partition 771, the desulfurizing agent 761, and the partition 770 are arranged in this order in the horizontal direction.

[0014] 4B, a gap 721 is formed between the partitions 771 and 770 on the vertically upper side of the desulfurization agent 761. Also, a gap 722 is formed between the partitions 772 and 771 on the vertically upper side of the desulfurization agent 762.

[0015] When the desulfurizer 700 is transported in a vehicle or the like while placed horizontally as shown in FIG. 4(b), and is subjected to vibration, the following phenomenon occurs: (1) Due to vibration, partition 771 is displaced in direction 780, causing a change in the width between partition 772 and partition 771, or a change in the width between partition 771 and partition 770; (2) The phenomenon (1) above causes the desulfurization agents 761 and 762 to flow and become finely divided; (3) Due to the phenomenon (2) above, the desulfurization agents 761 and 762 become more dense so that the vertically downward bias of the desulfurization agents 761 and 762 increases and the gaps 721 and 722 expand.

[0016] According to the investigations of the present inventors, When the gap 711 and the gap 712 are present in the vertical installation state of FIG. 4(a), When the desulfurization agents 761 and 762 are small in diameter and lightweight and tend to aggregate due to static electricity, Large deviations in the desulfurizing agents 761 and 762 and large gaps 721 and 722 are likely to occur.

[0017] 4(c) shows the state in which the desulfurizer 700 is placed vertically again after the above (3). Even when the desulfurizer 700 is returned from horizontal placement to vertical placement, the imbalance of the desulfurizing agents 761 and 762 is not completely eliminated. Therefore, unlike FIG. 4(a), after the desulfurizer 700 is returned to vertical placement, the upper surface 761s of the desulfurizing agent 761 and the upper surface 762s of the desulfurizing agent 762 are inclined from the horizontal direction.

[0018] Figure 4(d) is a partial enlargement of Figure 4(c). In Figure 4(d), gas flows 790a and 790b are part of gas flow 790. Desulfurization agent 761 has a portion 761a through which flow 790a passes and a portion 761b through which flow 790b passes. Compared to portion 761b, portion 761a is shorter, and therefore its desulfurization performance deteriorates more quickly.

[0019] If the desulfurization performance of the desulfurization agent 761 deteriorates unevenly such that the desulfurization performance of the portion 761a deteriorates relatively quickly, the overall desulfurization performance of the desulfurization agent 761 deteriorates due to the influence of the portion 761a. This means that the period during which the desulfurization agent 761 as a whole exhibits the expected desulfurization performance is shortened due to the influence of the deterioration of the portion 761a. A similar phenomenon occurs in the desulfurization agent 762.

[0020] 4(a), it is possible to provide a spring positioned vertically above the partition 770 and press the partition 770 toward the partition 772 with the spring, thereby eliminating the gaps 711 and 712. However, in a configuration in which the partition 771 separates the multiple desulfurizing agents 761 and 762 between the spring and the partition 772, it is difficult to avoid misalignment of the partition 771 in the direction 780 relative to the tube 750.

[0021] For this reason, even if a spring is used, the phenomenon (1) described above still occurs in the horizontally placed state shown in Fig. 4(b), causing the desulfurization agents 761 and 762 to flow, pulverize, and become unevenly distributed, resulting in uneven deterioration of the desulfurization performance and shortening the period during which the desulfurization agents 761 and 762 as a whole exhibit the expected desulfurization performance.

[0022] Therefore, the present inventors have investigated a technique suitable for suppressing the deterioration of the desulfurization performance of the desulfurizer due to transportation of the desulfurizer.

[0023] Hereinafter, embodiments will be described in detail with reference to the drawings. However, unnecessary detailed description may be omitted. For example, detailed description of well-known matters or redundant description of substantially the same configuration may be omitted.

[0024] The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter recited in the claims.

[0025] (Embodiment) FIG. 1 is a configuration diagram of a desulfurizer 100 according to an embodiment.

[0026] The desulfurizer 100 includes a container 105 and a plurality of desulfurization agents 160. The container 105 includes a lid 177, a lid 178, a cylinder 150, a partition 170, a partition 171, a partition 172, and a partition 173. The plurality of desulfurization agents 160 include a desulfurization agent 161 and a desulfurization agent 162.

[0027] The barrel 150 includes a sidewall 150w and an interior region 150h. The sidewall 150w defines the interior region 150h. The lid 177 has an opening 175. The lid 178 has an opening 176.

[0028] The tube 150 extends in a direction 180. Specifically, the direction 180 is the direction in which the central axis of the tube 150 extends.

[0029] 1, the tube 150 extends straight, and the direction 180 is a linear direction. However, the tube 150 may have a bent portion, and the direction 180 may change along the bend.

[0030] In this embodiment, the cylinder 150 is made of metal, such as stainless steel.

[0031] In this embodiment, the multiple desulfurizing agents 160 exist as clumps. In the example of Fig. 1, the number of desulfurizing agents 160 is two, namely, desulfurizing agent 161 and desulfurizing agent 162. However, the number of desulfurizing agents 160 may be three or more.

[0032] The desulfurizing agent 161 has a first composition. The desulfurizing agent 162 has a second composition. In this embodiment, the first composition and the second composition are different from each other. However, the first composition and the second composition may be the same.

[0033] In one example, the desulfurizing agent 161 and the desulfurizing agent 162 include a resin. The desulfurizing agent 161 and the desulfurizing agent 162 including a resin may be a desulfurizing agent having a small particle size and weight.

[0034] The gas enters the interior region 150h through opening 175. The gas then passes through a plurality of desulfurization agents 160 in the interior region 150h. The gas then exits the interior region 150h through opening 176. In the desulfurizer 100, such a flow 190 of gas is formed, and sulfur components in the gas are removed.

[0035] In one example, the gas is a fuel gas. After passing through the desulfurization agent 160, the fuel gas is supplied to a reformer. In the reformer, hydrogen is produced. The hydrogen is supplied to a fuel cell. In the fuel cell, electricity is generated.

[0036] In the internal region 150h, a partition 173, a partition 172, a desulfurizing agent 162, a partition 171, a desulfurizing agent 161, and a partition 170 are arranged in this order along a direction 180. A filter (not shown) is disposed between the partition 173 and the partition 172.

[0037] Hereinafter, the expressions "vertical installation" and "horizontal installation" may be used for the desulfurizer 100. When the desulfurizer 100 is vertically installed, the desulfurizing agents 161 and 162 are aligned vertically. When the desulfurizer 100 is horizontally installed, the desulfurizing agents 161 and 162 are aligned horizontally. The horizontal direction is a direction perpendicular to the vertical direction.

[0038] FIG. 2 is an enlarged view of the desulfurizer 100 according to the embodiment.

[0039] The container 105 includes a positioning structure 210. The positioning structure 210 positions the partition 171 relative to the tube 150 so as to prevent displacement of the partition 171 in the direction 180 relative to the tube 150. With this configuration, even if the desulfurizer 100 is transported in a horizontal position and vibrates, displacement of the partition 171 in the direction 180 relative to the tube 150 is suppressed. This is suitable for suppressing deterioration in the desulfurization performance of the desulfurizer 100 due to transportation of the desulfurizer 100 and providing a highly reliable desulfurizer 100. Note that, unless otherwise contradictory, "positioning" may be interpreted as "fixing." Specifically, the positioning structure 210 positions the partition 171 relative to the tube 150 so as to prevent parallel movement of the partition 171 in the direction 180 relative to the tube 150.

[0040] In this embodiment, the desulfurizer 100 can assume a specific posture. The specific posture is, for example, the posture of the desulfurizer 100 when the desulfurizer 100 is placed horizontally. In the specific posture, at least one pressing force selected from the group consisting of a first pressing force from the desulfurizer 161 and a second pressing force from the desulfurizer 162 is applied to the partition 171. In the specific posture, the positioning structure 210 prevents positional deviation (specifically, translation) caused by the at least one pressing force.

[0041] In this embodiment, in the positioning structure 210, the side wall 171w of the partition 171 is fitted into the side wall 150w of the tube 150. This fitting makes it easy to ensure a contact area between the side wall 171w and the side wall 150w. This is advantageous from the viewpoint of preventing misalignment of the partition 171 in the direction 180 relative to the tube 150.

[0042] Specifically, in this embodiment, the side wall 150w includes a spiral fitting portion (hereinafter, spiral fitting portion) 150x. The side wall 171w includes a fitting portion 171x. In the positioning structure 210, the fitting portion 171x fits into the spiral fitting portion 150x.

[0043] The partition 171 can be inserted while being rotated along the spiral fitting portion 150x, so that the position of the partition 171 in the direction 180 can be determined arbitrarily.

[0044] The tube 150 may be opaque when it is made of metal, etc. Even if the tube 150 is opaque, the partition 171 can be easily positioned with high precision by inserting the partition 171 along the spiral fitting portion 150x.

[0045] The spiral fitting portion 150x extends in a direction inclined from the direction 180. Therefore, even if a force in the direction 180 is applied to the partition 171, the partition 171 tends to move along the spiral fitting portion 150x in the inclined direction. This is advantageous from the viewpoint of suppressing displacement of the partition 171 in the direction 180 relative to the tube 150. Specifically, the spiral fitting portion 150x extends so as to revolve around the central axis of the tube 150.

[0046] In the illustrated example, the fitting portion 171x is a convex portion, and this convex portion fits into a concave portion formed by the spiral fitting portion 150x. In another example, the fitting portion 171x is a concave portion, and this concave portion fits into the convex portion formed by the spiral fitting portion 150x.

[0047] In this embodiment, the partition 171 includes a mesh 171m. The mesh 171m allows the gas to pass through, while preventing the desulfurization agent 161 and the desulfurization agent 162 from passing through.

[0048] The container 105 includes a positioning structure 220. The positioning structure 220 positions the partition 172 relative to the barrel 150 to prevent misalignment of the partition 172 in the direction 180 relative to the barrel 150. Specifically, the positioning structure 220 positions the partition 172 relative to the barrel 150 to prevent translation of the partition 172 in the direction 180 relative to the barrel 150.

[0049] In this embodiment, the side wall 172w of the partition 172 is fitted into the side wall 150w in the positioning structure 220. Specifically, in this embodiment, the side wall 172w includes a fitting portion 172x. In the positioning structure 220, the fitting portion 172x is fitted into the spiral fitting portion 150x. The partition 172 can be inserted while rotating along the spiral fitting portion 150x.

[0050] In the illustrated example, the fitting portion 172x is a convex portion, and this convex portion fits into a concave portion formed by the spiral fitting portion 150x. In another example, the fitting portion 172x is a concave portion, and this concave portion fits into the convex portion formed by the spiral fitting portion 150x.

[0051] In this embodiment, the partition 172 includes a mesh 172m. The mesh 172m allows the gas to pass through while preventing the desulfurization agent 162 from passing through.

[0052] The container 105 includes a positioning structure 230. The positioning structure 230 positions the partition 173 relative to the barrel 150 to prevent misalignment of the partition 173 in the direction 180 relative to the barrel 150. Specifically, the positioning structure 230 positions the partition 173 relative to the barrel 150 to prevent translation of the partition 173 in the direction 180 relative to the barrel 150.

[0053] In the present embodiment, the side wall 173w of the partition 173 is fitted into the side wall 150w in the positioning structure 230. Specifically, in the present embodiment, the side wall 173w includes a fitting portion 173x. In the positioning structure 230, the fitting portion 173x is fitted into the spiral fitting portion 150x. The partition 173 can be inserted while rotating along the spiral fitting portion 150x.

[0054] In the illustrated example, the fitting portion 173x is a convex portion, and this convex portion fits into a concave portion formed by the spiral fitting portion 150x. In another example, the fitting portion 173x is a concave portion, and this concave portion fits into the convex portion formed by the spiral fitting portion 150x.

[0055] In this embodiment, the partition 173 includes a mesh 173m. The mesh 173m allows gas to pass through. A filter is disposed on the mesh 173m. Even if powder of the desulfurization agent 162 passes through the mesh 173m, the filter prevents the powder from passing through.

[0056] In this embodiment, a filter is disposed above the mesh 173m, while no filter is disposed above the mesh 172m. This configuration can prevent the filter above the mesh 172m from being clogged with powder of the desulfurization agent 162, while allowing the filter above the mesh 173m to prevent the powder from passing through.

[0057] The positioning structure 230 includes a plurality of protrusions 235. The protrusions 235 protrude from the side wall 150w toward the interior region 150h. The protrusions 235 support the partition 173 and prevent the partition 173 from falling due to gravity. Specifically, the protrusions 235 are dowels.

[0058] In this embodiment, the protrusion 235 protrudes from the side wall 150w toward the internal region 150h and supports the partition 172 via the partition 173. The partition 171 is in contact with the desulfurizing agent 161 and the desulfurizing agent 162. The fact that the partition 171 is in contact with the desulfurizing agent 161 and the desulfurizing agent 162 is advantageous in that the engagement between the engagement portion 171x and the spiral engagement portion 150x exerts an effect of suppressing displacement of the partition 171. On the other hand, the protrusion 235 is exposed to the hollow space in the internal region 150h. Compared to the engagement between the engagement portion and the spiral engagement portion, the protrusion 235 is more likely to exert an effect of suppressing displacement of the partition even when exposed to the hollow space. The combination of the fitting structure of the fitting portion 171x and the spiral fitting portion 150x and the protrusion 235 is a structure that takes into consideration the arrangement of the plurality of desulfurizing agents 160 and the plurality of partitions 171, 172, and 173 in the inner region 150h.

[0059] The container 105 includes a positioning structure 200. The positioning structure 200 positions the partition 170 relative to the barrel 150 to prevent misalignment of the partition 170 in a direction 180 relative to the barrel 150. Specifically, the positioning structure 200 positions the partition 170 relative to the barrel 150 to prevent translation of the partition 170 in a direction 180 relative to the barrel 150.

[0060] In the present embodiment, the side wall 170w of the partition 170 is fitted into the side wall 150w in the positioning structure 200. Specifically, in the present embodiment, the side wall 170w includes a fitting portion 170x. In the positioning structure 200, the fitting portion 170x is fitted into the spiral fitting portion 150x. The partition 170 can be inserted while rotating along the spiral fitting portion 150x.

[0061] In the illustrated example, the fitting portion 170x is a convex portion, and this convex portion fits into a concave portion formed by the spiral fitting portion 150x. In another example, the fitting portion 170x is a concave portion, and this concave portion fits into the convex portion formed by the spiral fitting portion 150x.

[0062] In this embodiment, the partition 170 includes a mesh 170m. The mesh 170m allows the gas to pass through while preventing the desulfurization agent 161 from passing through.

[0063] In this embodiment, the positioning structure 220 can position the partition 172 at a position 225 relative to the cylinder 150 in the direction 180. The internal region 150h has a volume equal to the volume of the desulfurization agent 162 between the position 225 in the direction 180 and the position 215 in the direction 180. The spiral fitting portion 150x extends so as to straddle the position 215 in the direction 180. With this configuration, the partition 171 can be inserted along the spiral fitting portion 150x until there is no gap between the partition 171 and the desulfurization agent 162. Note that the direction from the position 225 toward the position 215 in the direction 180 is the same as the direction from the desulfurization agent 162 toward the desulfurization agent 161.

[0064] In this embodiment, the positioning structure 210 can position the partition 171 at a position 217 relative to the cylinder 150 in the direction 180. The internal region 150h has a volume equal to the volume of the desulfurization agent 161 between the position 217 in the direction 180 and the position 207 in the direction 180. The spiral fitting portion 150x extends so as to straddle the position 207 in the direction 180. Note that the direction from the position 217 toward the position 207 in the direction 180 is the same as the direction from the desulfurization agent 162 toward the desulfurization agent 161.

[0065] Fig. 3 is an explanatory diagram of the assembly of the desulfurizer 100. In Fig. 3, the spiral fitting portion 150x, the fitting portion 170x, the fitting portion 171x, the fitting portion 172x, the fitting portion 173x, and the like are not shown.

[0066] 3(a), a lid 177 is welded to the tube 150. The tube 150 is provided with a plurality of protrusions 235.

[0067] 3(b), the partition 173 with the filter disposed therein is inserted along the spiral fitting portion 150x until the partition 173 abuts the protrusion 235. Next, the partition 172 is inserted along the spiral fitting portion 150x until the partition 172 abuts the partition 173.

[0068] Next, as shown in FIG. 3(c), the desulfurizing agent 162 is filled on the partition 172.

[0069] Next, as shown in FIG. 3(d), the partition 171 is inserted along the spiral fitting portion 150x until the partition 171 comes into contact with the desulfurizing agent 162.

[0070] Next, as shown in FIG. 3(e), the desulfurizing agent 161 is filled on the partition 171.

[0071] 3(f), the partition 170 is inserted along the spiral fitting portion 150x until the partition 170 contacts the desulfurizing agent 161. Next, the lid 178 is welded to the cylinder 150.

[0072] In the illustrated example, the partitions 170, 171, 172, and 173 have fitting portions 170x, 171x, 172x, and 173x, respectively. Specifically, the fitting portions 170x, 171x, 172x, and 173x have the same structure and dimensions. This uniformity is advantageous from the viewpoint of standardizing multiple parts in the desulfurizer 100 and reducing costs.

[0073] However, it is not essential that the structures and dimensions of the partitions 170, 171, 172, and 173 be identical. For example, a configuration may be adopted in which the partition 171 has a fitting portion 171x that fits into the spiral fitting portion 150x, while at least one selected from the group consisting of the partitions 170, 172, and 173 does not have a fitting portion that fits into the spiral fitting portion 150x. The partition 170 can be positioned by the protrusion 235 even if it does not have the fitting portion 170x.

[0074] 1, the gas passes through the opening 175, the inner region 150h, and the opening 176 in this order. However, the gas may pass through the opening 176, the inner region 150h, and the opening 175 in this order.
