The flow path members 38 extend in the depth direction of the container through which the water vapor Wb flows, and a plurality of the flow path members 38 are arranged in the width direction of the container.

  As shown in FIG. 6B, the flow path member 38 is disposed below the top plate 37. As an example, the flow path member 38 is the reverse of the heat storage portion 42 (see FIG. 10) side as viewed from the container depth direction. It is U-shaped. Specifically, the flow path member 38 has a pair of side walls 38A whose plate surfaces face the container width direction, and an upper wall 38B that connects the upper ends of the pair of side walls 38A. As an example, the flow path member 38 is formed by pressing a stainless steel plate.

The plurality of side walls 38A are placed on the upper surface of the filter 39 (see FIG. 10).

[filter]
The filter 39 (see FIG. 10) is composed of a single metal foil formed in a single plate shape with the plate surface facing the vertical direction of the container, and stainless steel foil is used as an example. The filter 39 is rectangular when viewed from the top and bottom of the container, and has the same shape as the top plate 37 of the flow path portion 36.

The heat storage material 44 is formed in a flat rectangular parallelepiped (block) shape that spreads in the container width direction and the container depth direction as an example. The heat storage material 44 is an oxide of an alkaline earth metal as an example. A compact of calcium oxide (CaO) is used. This molded body is formed, for example, by kneading calcium oxide powder with a binder (for example, clay mineral) and firing. Furthermore, the heat storage material 44 is disposed in close contact with the filter 39 (see FIG. 10).

  Furthermore, in the reactor 20 shown in FIG. 10, the heat storage material 44 generates heat (heat radiation) with hydration combined with the water vapor Wb, and stores heat (heat absorption) with dehydration from which the water vapor Wb is desorbed. . And in reactor 20, it is set as the structure which can reversibly repeat heat dissipation and heat storage by reaction shown below.

  Further, the frame member 46 is formed in a frame shape in which the vertical direction of the container is opened, and surrounds the side surfaces of the heat storage material 44 in the container width direction and the container depth direction. Thereby, the expansion | swelling of the container width direction in the thermal storage material 44 and a container depth direction is restrained.

As another example of the heat medium, a fluid such as water may be used.

  The heat medium container 54 is open at the top in the vertical direction of the container, and the opening of the heat medium container 54 is covered with an attachment portion 80A of a regulating member 80 described later. The heat transfer medium container 54 includes a bottom plate 54A and side plates 54B, 54C, 54D, and 54E that rise upward in the vertical direction of the container at the edge of the bottom plate 54A. The side plate 54B and the side plate 54D are arranged to face each other in the container depth direction, and the side plate 54C and the side plate 54E are arranged to face each other in the container width direction.

  Further, a through hole 59A penetrating in the depth direction of the container is formed on the end side (left side in the drawing) of the side plate 54B in the container width direction. Further, a through hole 59B penetrating in the depth direction of the container is formed on the end side (right side in the figure) of the side plate 54D in the container width direction. One end of a pipe 57A is connected to the through hole 59A, and one end of the pipe 57B is connected to the through hole 59B. Thereby, the heat medium oil (not shown) that has flowed into the heat medium container 54 from the pipe 57A through the through hole 59A passes through the heat medium flow path C2 and the through hole 59B described later of the heat medium flow path member 58. It flows out to the pipe 57B.

  As shown in FIG. 4B, the heat medium flow path member 58 has a rectangular wave shape in which irregularities are seen when viewed from the container depth direction, and is formed by pressing a stainless steel plate as an example.

In addition, the heat medium flow path member 58 has an upper wall 58B that connects the upper ends of the two side walls 58A every other container width direction, and two other side walls 58A that are shifted from the upper wall 58B every other container wall direction. And a lower wall 58C connecting the lower ends of the two.

  Thus, the heat medium flow path member 58 is along the container depth direction in which the heat medium oil flows, and the plurality of side walls 58A are arranged in the container width direction. And in the heat medium flow path member 58, between the some side wall 58A becomes the heat medium flow path C2 into which heat medium oil flows.

  And in the thermal storage unit 30, the heat exchange part 52, the thermal storage part 42, the filter 39, and the flow-path part 36 are laminated | stacked from the bottom to the top in this order in the container up-down direction. That is, in the present embodiment, the vertical direction of the container is the stacking direction.

  The restricting member 80 will be described later.

<Restraining part>
As shown in FIG. 7, the restraining portion 62 is composed of restraining members 63 and 64 disposed on the upper and lower sides of the heat storage units 30 and 32 in the vertical direction of the container, and bolts 68 and nuts that connect the restraining members 63 and 64. 69. In addition, since the restraint member 63 and the restraint member 64 are the same structures as an example, the restraint member 63 is demonstrated and description of the restraint member 64 is abbreviate | omitted. In FIG. 7, only one set of bolts 68 and nuts 69 is shown, and the remaining three sets of bolts 68 and nuts 69 are not shown.

  The restraining member 63 is welded to the plurality of rectangular tube members 65 arranged in the container depth direction with the container width direction as the longitudinal direction, and the plurality of rectangular tube members 65 welded along the container depth direction. And a plurality of rectangular tube members 66 for connecting 65. Further, the restraining member 63 has a plurality of rectangular tube members 67 that are coaxial with the rectangular tube member 66 and project outward from the respective rectangular tube members 65 in the container depth direction.

  The plurality of rectangular tube members 65, 66, and 67 have the same height in the vertical direction of the container. That is, the plurality of rectangular tube members 65, 66, and 67 are arranged on substantially the same plane in the vertical direction of the container.

  In addition, the rectangular tube material 67 is formed with a through hole 67A penetrating in the vertical direction of the container. The through hole 67A has a size that allows the bolt 68 to be inserted therethrough. Here, with the restraining members 63 and 64 sandwiching the heat storage units 30 and 32, the bolts 68 are inserted through the through holes 67 </ b> A of the restraining member 63 and the through holes 67 </ b> A of the restraining member 64, and the nut 69 is fastened. The heat storage units 30 and 32 are restrained by the restraining portion 62. That is, the restraining part 62 restrains the heat storage units 30 and 32 in the container vertical direction (stacking direction). In addition, the volt | bolt 68 is arrange | positioned with respect to the thermal storage units 30 and 32 at the near side and back side of a container depth direction.

(Operation of the overall configuration)
Next, the operation of the overall configuration will be described.

  When the heat stored in the reactor 20 is dissipated in the heat storage system 10, the liquid phase part is opened by the heater 18 of the evaporative condenser 12 with the on-off valve 19 opened as shown in FIG. 9A. 16B of water Wa is evaporated. Then, the generated water vapor Wb moves in the water vapor flow path 14 in the direction of arrow B and is supplied into the reactor 20.

  Subsequently, as shown in FIG. 10, in the reactor 20, the supplied water vapor Wb flows in the flow path portion 36 of the heat storage unit 30 and in the flow path portion 36 of the heat storage unit 32. And the water vapor | steam Wb in each flow-path part 36 contacts each heat storage material 44 (refer FIG. 5) through the filter 39, and the heat storage material 44 radiates heat, producing hydration reaction. This heat is transported to the object to be heated by the heat medium oil flowing in the heat exchange section 52.

  On the other hand, as shown in FIG. 9B, when heat is stored in the heat storage material 44 (see FIG. 5) of the reactor 20 in the heat storage system 10, the pipe 57A, heat exchange is performed with the on-off valve 19 opened. Heat medium oil heated by a heat source (not shown) is circulated in the part 52 and the pipe 57B. By being heated by this heat transfer oil, the heat storage material 44 undergoes a dehydration reaction, and this heat is stored in the heat storage material 44. At this time, the water vapor Wb dehydrated from the heat storage material 44 flows from the flow path portion 36 through the water vapor flow path 14 in the direction of arrow A and is introduced into the evaporative condenser 12. Then, in the vapor phase portion 16 </ b> A of the evaporative condenser 12, the water vapor Wb is cooled by the refrigerant flowing through the refrigerant flow path 17, and the condensed water Wa is stored in the liquid phase portion 16 </ b> B of the storage container 16.

  It supplements, referring the cycle (an example) of the thermal storage system 10 about the thermal storage of the thermal storage material 44 demonstrated above, and thermal radiation. FIG. 8 shows a cycle of the heat storage system 10 (see FIG. 11) at the pressure equilibrium point shown in the PT diagram. In FIG. 8, the upper isobaric line shows a dehydration (endothermic) reaction, and the lower isobaric line shows a hydration (exothermic) reaction. Note that FIG. 11 is referred to for the configuration of the heat storage system 10.

  In this cycle, for example, when the temperature of the heat storage material 44 is stored at 410 [° C.], the water vapor Wb has an equilibrium temperature of 50 [° C.]. In the heat storage system 10, the water vapor Wb is cooled to 50 [° C.] or less by heat exchange with the refrigerant in the refrigerant flow path 17 in the evaporative condenser 12, and condensed to become water Wa.

  On the other hand, by heating with the heater 18, water vapor having a vapor pressure corresponding to the temperature of the heater 18 is generated. For example, in the cycle shown in FIG. 8, it is understood that when water vapor is generated at 5 [° C.], the heat storage material 44 radiates heat at 315 [° C.]. Thus, in the heat storage system 10 in which the inside is vacuum degassed, heat can be pumped from a low-temperature heat source in the vicinity of 5 [° C.] to obtain a high temperature of 315 [[° C.].

(Main part configuration)
Next, the regulating member 80 attached to the heat medium container 54 of the heat exchange unit 52 will be described.

  As shown in FIG. 4 (A), the regulating member 80 is formed by pressing a sheet metal, and includes a mounting portion 80A that covers the opening of the heat medium container 54 from above, and an edge portion of the mounting portion 80A. And a pair of contact portions 80B that rise upward in the vertical direction.

  The mounting portion 80A has a rectangular shape when viewed from the container vertical direction with the plate surface facing the container vertical direction (an example of the stacking direction), and is sandwiched between the heat storage unit 42 (see FIG. 2A) and the heat exchange unit 52. It is supposed to be. And 80 A of attachment parts are attached to the upper end surface of the side plates 54B, 54C, 54D, 54E of the heat-medium container 54 by welding. Thus, the heat medium flowing inside the heat medium container 54 is prevented from leaking outside.

  Further, the pair of contact portions 80B face each other in the container width direction, and the plate surface of the contact portion 80B faces the container width direction (an example of the orthogonal direction).

  As shown in FIG. 2A, the distance (dimension D in the drawing) between the pair of contact portions 80B is the length of the heat storage portion 42 in the container width direction (dimension E1 in the drawing), the flow path portion 36, and the filter. It is determined in consideration of the length of 39 (dimension E2 in the figure) and the length of the heating medium container 54 (dimension E3 in the figure).

  Furthermore, the height of the contact portion 80B (dimension H in the drawing) is the height of the heat storage portion 42 in the vertical direction of the container (dimension J in the drawing), and the height of the flow path portion 36 and the filter 39 (dimension K in the drawing). And the height of the heat medium container 54 (dimension L in the figure).

  Specifically, the dimensions E1, E2, and E3 have the same length. The dimension D is equal to or larger than the dimension E1, the dimension E2, and the dimension E3.

  The dimension H is larger than the dimension (J + K) obtained by adding the dimension K to the dimension J, and smaller than the dimension (J + K + L) obtained by adding the dimension K and the dimension L to the dimension J.

  With this configuration, when each member is stacked on the heat medium container 54 to which the regulating member 80 is attached from the upper side in the container vertical direction, the regulating member 80 regulates the position of each member in the container width direction. (Details will be described later).

(Effects of main components)
Next, the operation of assembling the heat storage unit 30 by stacking the respective members, the action of the regulating member 80 accompanying the expansion of the heat storage material 44, and the like will be described.

  About the operation | work which assembles the thermal storage unit 30, as shown to FIG. 1 (A) and FIG. 2 (A), the thermal storage part 42 is accumulated on the heat exchange part 52 from the upper direction of a container up-down direction, and also the thermal storage part 42 The channel portion 36 and the filter 39 are stacked from above in the vertical direction of the container.

  When the heat storage part 42 is stacked on the heat exchange part 52 from above in the container vertical direction, the position of the heat storage part 42 in the container width direction is regulated by the heat storage part 42 hitting the contact part 80B of the regulating member 80.
