Description

  The present invention relates to a purifier.

  DESCRIPTION OF RELATED ART Conventionally, the desulfurizer provided with the container which has an inlet part and an outlet part, and the desulfurization agent with which the inside of the container was filled is known (for example, refer patent document 1, 2). In this desulfurizer, a desulfurization reaction is performed between the gas flowing from the inlet portion to the outlet portion inside the container and the desulfurizing agent.

Japanese Patent No. 4613022 JP 2012-149117 A

  However, in a conventional purifier including the above-described desulfurizer, if a gap is formed between the peripheral wall portion of the container and the purifying agent by using, for example, a granulating agent as the purifying agent, the inside of the container The fluid on the peripheral wall side (outer diameter side) is easier to flow than the center side of the container (the flow resistance becomes lower). For this reason, the flow rate is higher on the peripheral wall portion side of the container than on the center side of the container, and there is a possibility that a drift occurs inside the container.

  Further, when a drift occurs in the interior of the container in this way, the purification reaction by the purification agent is promoted on the peripheral wall portion side of the container rather than the center side of the container. In this case, since the purifier reaches the end of its life at the timing when the purifying agent no longer undergoes the purifying reaction on the peripheral wall side of the container (the timing of breakthrough), the life of the purifier becomes shorter than expected from the original performance. There is a fear.

  Then, an object of this invention is to provide the purifier which can extend a lifetime.

  In order to achieve the above object, the purifier according to claim 1 is a container having an inlet part and an outlet part, and is filled in the container and disposed between the inlet part and the outlet part. The cleaning agent is disposed between the inlet portion side end portion and the outlet portion side end portion of the cleaning agent, protrudes from the peripheral wall portion of the container to the inside of the container, and And a drift suppression unit provided along the circumferential direction.

  According to this purifier, the drift suppressing part is disposed between the end on the inlet side and the end on the outlet side of the purifier. The drift suppressing portion protrudes from the peripheral wall portion of the container to the inside of the container and is provided along the circumferential direction of the container. Accordingly, since the flow of fluid on the peripheral wall portion side (outer diameter side) of the container can be suppressed by the drift suppressing portion, the fluid flow velocity on the peripheral wall portion side of the container is brought close to the fluid flow velocity on the center side of the container. Can do. Thereby, since the drift in the inside of a container can be suppressed, the purification reaction by a purification agent can be similarly performed on the peripheral wall side and the center side of the container. As a result, the lifetime of the purifier can be extended as compared with the conventional purifier that does not include the drift suppressing portion.

  A purifier according to a second aspect is the purifier according to the first aspect, wherein the drift suppressing portion extends in a ring shape along a circumferential direction of the container.

  According to this purifier, the drift suppressing part extends in an annular shape along the circumferential direction of the container. Therefore, the flow of the fluid on the peripheral wall portion side of the container can be suppressed over the circumferential direction of the container. Thereby, the drift in the inside of a container can be suppressed more effectively.

  The purifier according to claim 3 is the purifier according to claim 1 or 2, wherein a plurality of the drift suppressing portions are provided at intervals in the direction of fluid flow inside the container. It is said that.

  According to this purifier, a plurality of drift suppressing portions are provided at intervals in the direction of fluid flow inside the container. Therefore, the flow of fluid on the peripheral wall portion side of the container can be suppressed by the drift suppressing portion at a plurality of positions in the direction of fluid flow. Thereby, the drift in the inside of a container can be suppressed over the direction of the flow of the fluid in the inside of a container.

  The purifier according to claim 4 is the purifier according to any one of claims 1 to 3, wherein the drift suppressing portion is configured such that a fluid flow direction in the container is a plate thickness direction. It is set as the structure formed in the plate shape.

  According to this purifier, the drift suppressing portion is formed in a plate shape in which the direction of fluid flow inside the container is the plate thickness direction. Therefore, it is possible to suppress the installation space of the drift suppression unit from expanding in the direction of fluid flow inside the container. Thereby, it can suppress that a container enlarges in the direction of the flow of a fluid. Further, when the fluid flowing along the peripheral wall portion of the container hits the plate-shaped drift suppressing portion, the fluid peels from the peripheral wall portion of the container, and the flow rate of the fluid flowing on the peripheral wall portion side of the container is suppressed. Thereby, the flow velocity distribution of the fluid passing through the purifying agent can be made closer to uniform.

  The purifier according to claim 5 is the purifier according to any one of claims 1 to 4, wherein the drift suppression part is separated from the container.

  According to this purifier, since the drift suppression unit is separate from the container, the manufacture of the container can be facilitated (the manufacturing of the container including the drift suppression unit is prevented from being complicated. Can do).

  A purifier according to a sixth aspect is the purifier according to any one of the first to fourth aspects, wherein the drift suppressing portion is formed integrally with the container.

  According to this purifier, since the drift suppressing part is formed integrally with the container, it is possible to suppress an increase in the number of parts and an increase in the manufacturing process.

  A purifier according to a seventh aspect is the purifier according to any one of the first to sixth aspects, wherein the drift suppressing portion makes the flow velocity distribution of the fluid passing through the purifier uniform. Further, the protruding amount from the peripheral wall portion of the container is set.

  According to this purifier, the amount of protrusion from the peripheral wall portion of the container is set in the drift suppressing portion so that the flow velocity distribution of the fluid passing through the purifier is uniform. Thereby, since the whole purifier can be used up, the lifetime of a purifier can be extended more effectively.

  As described in detail above, according to the present invention, the life of the purifier can be extended.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the purifier 10 according to one embodiment of the present invention includes a container 12, a purifying agent 14, and a drift suppression plate 16 that is an example of a drift suppression unit.

  As an example, the container 12 is formed of a cylindrical body having a circular cross section having a cylindrical peripheral wall portion 17 and a pair of end portions 18 and 20 that close both ends in the axial direction of the peripheral wall portion 17. An inlet 22 is formed at one end 18 of the container 12, and an outlet 24 is formed at the other end 20 of the container 12. The inlet portion 22 and the outlet portion 24 are formed in a tubular shape extending along the axial direction of the container 12, and are provided on the central axis of the container 12. In FIG. 1, a part of the container 12 is cut away so that the purifier 14 inside the container 12 can be seen. The same applies to FIGS. 3, 4, 5, and 9, which will be described later.

  The cleaning agent 14 is, for example, an aggregate such as a granular material or a columnar block, and is filled in the container 12. The purifier 14 is disposed between the inlet portion 22 and the outlet portion 24 inside the container 12. As shown in FIG. 2, a pair of holding members 26 and 28 that are separated in the axial direction of the container 12 are provided inside the container 12. Each holding member 26, 28 has an annular plate member 30 and a mesh 32 provided inside the plate member 30, and the purifying agent 14 is contained in the container 12 by the pair of holding members 26, 28. It is held from both sides in the axial direction. The pair of holding members 26 and 28 are respectively separated from the end portions 18 and 20 on both sides in the axial direction of the container 12, and thereby, between the inlet portion 22 and the purifying agent 14 and between the purifying agent 14 and the outlet portion. Clearances 34 and 36 are respectively provided between the two.

  In the purifier 10, a fluid flows into the container 12 through the inlet portion 22, and the fluid that has flowed performs a purification reaction with the purifier 14 when flowing through the container 12, and then It is discharged out of the container 12 through the outlet 24. The purifier 10 provided with the purifier 14 is preferably used as a desulfurizer (room temperature adsorption desulfurizer) in a pretreatment stage in a fuel cell system using city gas, for example, and the purifier 10 is a desulfurizer. When used as, the purifier 14 is a desulfurizing agent. As this desulfurizing agent, for example, silver zeolite is used.

  The drift suppression plate 16 is for suppressing the drift in the container 12 as will be described in detail later. The drift suppression plate 16 is disposed between the end portion 14 </ b> A on the inlet portion 22 side and the end portion 14 </ b> B on the outlet portion 24 side of the purifier 14, and more specifically, the inlet portion 22 of the purifier 14. It is arranged at the center between the end portion 14A on the side and the end portion 14B on the outlet portion 24 side.

  The drift suppression plate 16 is formed of an annular plate material that is separate from the container 12, and the axial direction of the container 12 (the direction of fluid flow inside the container 12) is the plate thickness direction. It is assembled inside the peripheral wall 17. The drift suppressing plate 16 protrudes from the peripheral wall 17 to the inside of the container 12 and extends annularly along the circumferential direction of the container 12 in a state assembled to the inner side of the peripheral wall 17. The drift suppression plate 16 is formed, for example, by punching a flat metal plate and fitted inside the peripheral wall portion 17 or fixed inside the peripheral wall portion 17 by welding or the like. .

  In addition, the drift suppressing plate 16 more preferably has a uniform flow velocity distribution of the fluid passing through the purifier 14 (particularly, a flow velocity distribution of the fluid passing through the purifier 14 on the downstream side of the drift suppressing plate 16). The protrusion amount from the surrounding wall part 17 is set so that it may become. The amount of protrusion of the drift suppression plate 16 from the peripheral wall portion 17 is set based on the average flow velocity, average flow rate, and cross-sectional area of the container 12 flowing from the inlet portion 22. The fact that the flow velocity distribution of the fluid passing through the purifying agent 14 is uniform can be grasped by, for example, examining a simulation or a reaction acceleration state by the purifying agent 14.

  In the purifier 10 provided with the drift suppression plate 16, for example, one end portion 18 is a lid member separate from the peripheral wall portion 17 and the other end portion 20 constituting the main body portion of the container 12. The And this purifier 10 is assembled in the following manner. That is, half of the amount of the purifying agent 14 is poured into the inside of the peripheral wall portion 17 in a state where the one end portion 18 that is a lid member is removed from the peripheral wall portion 17. Next, the drift suppression plate 16 is attached to the inner side of the peripheral wall portion 17, and then the remaining amount of the purifier 14 is poured into the inner side of the peripheral wall portion 17. The purifier 10 is assembled by attaching one end 18 to the peripheral wall 17.

  Next, the operation and effect of one embodiment of the present invention will be described.

  In order to clarify the operation and effect according to the embodiment of the present invention, a conventional example will be described first. 9 and 10 show a purifier 70 according to a conventional example. In the purifier 70 according to the conventional example, the same components as those of the purifier 10 according to the embodiment of the present invention described above are denoted by the same reference numerals, and the description thereof is omitted. The purifier 70 according to this conventional example is configured such that the drift suppression plate 16 is omitted from the purifier 10 according to the above-described embodiment of the present invention.

  However, in the purifier 70 according to this conventional example, since a gap is formed between the purifying agent 14 constituted by a granular agent or the like and the peripheral wall portion 17 of the container 12, the peripheral wall portion 17 is inside the container 12. On the side (the outer diameter side of the container 12), the fluid flows more easily than the center side of the container 12 (the flow resistance decreases). For this reason, as shown in FIG. 10, the flow velocity Va of the fluid on the peripheral wall portion 17 side of the container 12 becomes higher than the flow velocity Vb of the fluid on the center side of the container 12, and there is a possibility that drift occurs inside the container 12. . In particular, the drift in the inside of the container 12 becomes prominent on the downstream side of the central portion in the axial direction of the container 12.

  Further, when a drift occurs inside the container 12 in this way, the purification reaction by the purification agent 14 is promoted on the peripheral wall 17 side of the container 12 rather than on the center side of the container 12. In FIG. 10, the area | region which became unable to perform purification reaction among the purification agents 14 is shown by the dark dot, and the area | region which can perform purification reaction among the purification agents 14 is shown by the thin dot. In such a purifier 70, the purifier 70 reaches the end of its life at the timing when the purifying agent 14 no longer performs the purifying reaction on the peripheral wall 17 side of the container 12 (breakthrough timing). The life of the purifier 70 may be shorter than expected.

  On the other hand, according to the purifier 10 according to this embodiment shown in FIG. 2, the drift is suppressed between the end portion 14 </ b> A on the inlet portion 22 side and the end portion 14 </ b> B on the outlet portion 24 side of the purifier 14. A plate 16 is arranged. The drift suppression plate 16 protrudes from the peripheral wall portion 17 of the container 12 to the inside of the container 12 and is provided along the circumferential direction of the container 12. Therefore, the flow of fluid on the peripheral wall portion 17 side (outer diameter side) of the container 12 can be suppressed by the drift suppression plate 16, so that the fluid flow velocity Va on the peripheral wall portion 17 side of the container 12 is set to the center side of the container 12. Can be close to the fluid flow velocity Vb. Thereby, since the drift in the inside of the container 12 can be suppressed, the purification reaction by the purification agent 14 can be similarly performed on the peripheral wall portion 17 side and the center side of the container 12. As a result, the lifetime of the purifier 10 can be extended as compared with the conventional purifier that does not include the drift suppression plate 16.

  In particular, the drift suppressing plate 16 has a uniform flow velocity distribution of the fluid passing through the purifying agent 14 (more specifically, a flow velocity distribution of the fluid passing through the purifying agent 14 on the downstream side of the drift suppressing plate 16). In addition, the amount of protrusion from the peripheral wall portion 17 is set. Accordingly, since the entire purifying agent 14 can be used up, the life of the purifier 10 can be more effectively extended.

  The drift suppression plate 16 extends in an annular shape along the circumferential direction of the container 12. Therefore, since the flow of the fluid on the peripheral wall portion 17 side of the container 12 can be suppressed over the circumferential direction of the container 12, it is possible to more effectively suppress the drift in the container 12. .

  Moreover, the drift suppression plate 16 is formed in a plate shape in which the axial direction of the container 12 (the direction of fluid flow in the container 12) is the plate thickness direction. Therefore, it is possible to suppress the installation space of the drift suppression plate 16 from expanding in the axial direction of the container 12. Thereby, it can suppress that the container 12 enlarges to an axial direction. Further, when the fluid flowing along the peripheral wall portion 17 of the container 12 hits the drift suppression plate 16, the fluid peels from the peripheral wall portion 17, and the flow rate of the fluid flowing on the peripheral wall portion 17 side of the container 12 is suppressed. . Therefore, this also makes it possible to make the flow velocity distribution of the fluid passing through the purifier 14 uniform.

  In addition, since the drift suppression plate 16 is separate from the container 12, the manufacture of the container 12 can be facilitated (the manufacturing of the container 12 including the drift suppression plate 16 is prevented from being complicated. Can do).

  Further, as described above, in the assembling process of the purifier 10, it is only necessary to attach the drift suppressing plate 16 to the inside of the peripheral wall portion 17 in a state where half the amount of the purifier 14 is poured into the peripheral wall portion 17. The purifier 10 can be assembled in the same procedure as the conventional purifier 70 that does not have the suppression plate 16. Thereby, compared with the conventional purifier 70 which does not have the drift suppression board 16, it can suppress that cost increases.

  Next, a modification of one embodiment of the present invention will be described.

  In the said embodiment, although the purifier 10 was suitably used as a desulfurizer (room temperature adsorption desulfurizer) in a fuel cell system, for example, things other than a desulfurizer (for example, a heat desulfurizer or a hydrogenation) In addition to a desulfurizer, a general purifier such as a catalyst may be used. Moreover, the purifier 10 may be used at normal temperature, or may be used at high temperature. Further, the cleaning agent 14 may be a material other than the desulfurizing agent. In addition, when the purifier 10 is used at room temperature, the drift suppression plate 16 may be formed of stainless steel, or may be formed of plastic or paper. Further, when the purifier 10 is used at a high temperature, the drift suppression plate 16 may be formed of stainless steel. Moreover, the purifier 10 may be configured to purify liquid as well as gas. Further, when the purifier 10 is configured to purify a liquid, for example, an ion exchange resin may be used as the purifier 14.

  Moreover, although the container 12 was formed in the cross-sectional circle shape, you may be formed in shapes (for example, square, a polygon, an ellipse, etc.) other than circular cross section. Moreover, although the container 12 was formed straight in the direction which connects the inlet part 22 and the outlet part 24, you may form in shapes (for example, bent shape) other than a straight shape.

  Moreover, although the clearance gaps 34 and 36 were each provided between the edge parts 18 and 20 of the axial direction both sides of the container 12, and the purifier 14, these clearance gaps 34 and 36 do not need to be provided ( The cleaning agent 14 may be in contact with the end portions 18 and 20 on both axial sides of the container 12).

  Moreover, although the inlet part 22 and the outlet part 24 were provided on the central axis of the container 12, as shown in FIG. 3, the inlet part 22 and the outlet part 24 deviate from the central axis of the container 12 ( It may be provided at an eccentric position). In addition, one of the inlet portion 22 and the outlet portion 24 is provided on the central axis of the container 12, and the other of the inlet portion 22 and the outlet portion 24 is provided at a position deviated from the central axis of the container 12 (an eccentric position). May be. Further, the inlet portion 22 and the outlet portion 24 may be provided on one side and the other side of the peripheral wall portion 17 in the axial direction, respectively. In this case, the inlet portion 22 and the outlet portion 24 may extend toward the radially outer side of the peripheral wall portion 17.

  In addition, the drift suppression plate 16 is disposed at the center between the end portion 14A on the inlet portion 22 side and the end portion 14B on the outlet portion 24 side of the purifying agent 14, but the inlet portion 22 side of the purifying agent 14 side. As long as it is between the end part 14A of this and the end part 14B by the side of the exit part 24, you may arrange | position in any position.

  Moreover, although the drift suppression plate 16 is formed in an annular plate shape extending along the circumferential direction of the container 12, each of the drift suppression plates 16 protrudes from the peripheral wall portion 17 of the container 12 to the inside of the container 12. A plurality of tongue-shaped drift suppression plates may be provided, and the plurality of drift suppression plates may be annularly arranged along the circumferential direction of the container 12.

  Further, the drift suppression plate 16 is formed perpendicular to the peripheral wall portion 17 of the container 12 in the longitudinal sectional view of the purifier 10, but the inlet portion with respect to the direction perpendicular to the peripheral wall portion 17 of the container 12. You may incline to 22 side or the exit part 24 side.

  In addition, although one drift suppression plate 16 is provided inside the container 12, as shown in FIG. 4, the container 12 has an axial direction (fluid in the container 12 inside). A plurality of drift suppression plates 16 may be provided at intervals in the direction of the flow. In this case, the number of the plurality of drift suppression plates 16 may be three or more. Thus, when a plurality of drift suppression plates 16 are provided at intervals in the axial direction of the container 12, the flow of fluid on the peripheral wall portion 17 side of the container 12 is drifted at a plurality of positions in the axial direction of the container 12. It can be suppressed by the suppression plate 16. Thereby, the drift in the inside of the container 12 can be suppressed over the axial direction of the container 12.

  In the above embodiment, the drift suppression plate 16 is separate from the container 12, but may be formed integrally with the container 12.

  Moreover, in order to suppress the drift in the container 12, the plate-shaped drift suppression board 16 was provided in the container 12, but the drift suppression part formed in shapes other than plate shape is provided. May be.

  In addition, for example, as shown in FIG. 5, by forming a constricted portion 44 at the central portion in the axial direction of the container 12, the container 12 protrudes from the peripheral wall portion 17 of the container 12 to the inside of the container 12 and The drift suppression part 46 extended cyclically | annularly along a direction may be formed. Thus, when the drift suppression part 46 is formed integrally with the container 12, an increase in the number of parts can be suppressed and an increase in the manufacturing process can be suppressed.

  Moreover, in the said embodiment, as shown in FIG. 6, the mesh 48 may be provided inside the drift suppression board 16 formed in the annular | circular shape. When the mesh 48 is provided inside the drift suppressing plate 16 as described above, the mesh 48 can suppress the flow of the purifier 14 (see FIG. 2 and the like).

  In addition, the modification which can be combined among the said several modification can be implemented combining suitably.

  Next, a comparative experiment between the purifier according to the embodiment of the present invention and the purifier according to the conventional example will be described.

  FIG. 11 shows experimental conditions relating to the comparative experiment. In this comparative experiment, adsorbent, adsorbent capacity, test tube diameter (container diameter), gas used as fluid, gas flow rate, SV (space velocity), LV (linear velocity), set temperature, set dew point, set TBM The concentration and the set DMS concentration are as shown in FIG. Further, as shown in FIG. 12, the inner and outer diameters of the drift suppressing plate used in the purifier according to the embodiment of the present invention are 9.4 mm and 15.4 mm, respectively. As shown in FIG. 13, in this comparative experiment, a purifier according to an embodiment of the present invention uses one drift suppression plate and two drift suppression plates. Moreover, as a purifier which concerns on a prior art example, what does not have a drift suppression board is used.

  14 and 15 show the results of comparative experiments. As shown in FIG. 14, the breakthrough time and the total sulfur adsorption amount increase in the case where the drift suppression plate is provided (one embodiment of the present invention) compared to the case where the drift suppression plate is not provided (conventional example). To do. Further, when there are two drift suppression plates, the total sulfur adsorption amount and breakthrough time are increased as compared with the case where there is only one drift suppression plate.

  Thus, according to one Embodiment of this invention, it became clear that the lifetime of a purifier is extended rather than the purifier which concerns on the prior art which is not equipped with a drift suppression board.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and other various modifications can be made without departing from the spirit of the present invention. It is.

  Next, a reference example will be described.

[First Reference Example]
The purifier 50 according to the first reference example shown in FIG. 7 has a structure changed as follows instead of having the drift suppression plate 16 with respect to the purifier 10 according to the embodiment of the present invention described above. Yes.

  That is, the purifier 14 filled in the container 12 has a center layer 51 and an outer layer 52 that are composed of purifiers 54A and 54B having different sizes. The center layer 51 is disposed on the center side of the container 12 and has a low flow resistance by being configured by the large purification agent 54A. The outer layer 52 is disposed on the peripheral wall 17 side (outer diameter side) of the container 12 with respect to the center layer 51 (is provided in an annular shape), and is constituted by a small purification agent 54B rather than a large purification agent 54A. Thus, the distribution resistance is higher than that of the central layer 51.

  In the purifier 50, for example, a cylindrical jig is inserted inside the container 12, and a large purification agent 54 </ b> A is poured inside the jig, and a small purification agent 54 </ b> B is placed outside the jig. Then, the center layer 51 and the outer layer 52 are formed inside the container 12 by pulling out the jig from the container 12.

  As in this first reference example, when the outer layer 52 has a lower flow resistance than the center layer 51, the flow of fluid on the peripheral wall 17 side (outer diameter side) of the container 12 can be suppressed. Therefore, the fluid flow velocity Va on the peripheral wall 17 side of the container 12 can be made closer to the fluid flow velocity Vb on the center side of the container 12. Thereby, since the drift in the inside of the container 12 can be suppressed, the purification reaction by the purification agent 14 can be similarly performed on the peripheral wall portion 17 side and the center side of the container 12. As a result, the life of the purifier 50 can be extended as compared with the conventional purifier in which the particle size of the purifier is uniform.

  If the flow resistance of the central layer 51 and the outer layer 52 (the particle diameters and ratios of the purifying agents 54A and 54B) are set so that the flow velocity distribution of the fluid passing through the purifying agent 14 is uniform, the purification is performed. Since the entire agent 14 can be used up, the life of the purifier 50 can be extended more effectively.

[Second Reference Example]
The purifier 60 according to the second reference example shown in FIG. 8 has a structure changed as follows instead of having the drift suppression plate 16 with respect to the purifier 10 according to the above-described embodiment of the present invention. Yes.

  In other words, the peripheral wall portion 17 of the container 12 is formed with a plurality of protrusions 62 that protrude inward of the container 12 and are arranged in the circumferential direction of the container 12. And the clearance gap between the surrounding wall part 17 and the purification | cleaning agent 14 is obstruct | occluded by these several protrusion parts 62. FIG.

  As described above, the gap between the peripheral wall portion 17 and the purifying agent 14 is blocked by the plurality of protrusions 62 that protrude from the peripheral wall portion 17 of the container 12 to the inside of the container 12 and are arranged in the circumferential direction of the container 12. If it is made, the flow of the fluid in the peripheral wall part 17 side (outer diameter side) of the container 12 can be suppressed. As a result, the flow velocity of the fluid on the peripheral wall portion 17 side of the container 12 can be brought close to the flow velocity of the fluid on the center side of the container 12, so that drift in the container 12 can be suppressed. As a result, since the purification reaction by the purification agent 14 can be similarly performed on the peripheral wall 17 side and the center side of the container 12, the life of the purifier 60 is longer than that of the conventional purifier that does not include the plurality of protrusions 62. Can be stretched.

  Note that if the shape and the amount of protrusion of the plurality of protrusions 62 are set so that the flow velocity distribution of the fluid passing through the purifier 14 is uniform, the entire purifier 14 can be used up. The life of the vessel 60 can be extended more effectively.

  Next, technical ideas derived from the first reference example and the second reference example will be described below.
