(Other parts)
As shown in FIGS. 7-9, the lamination | stacking unit 90 is the apparatus vertical direction (lamination direction) of the reaction medium diffusion layer 36, the filter 34, the thermal storage material layer 32, and the heat | fever fluidization part 50 which comprise the lamination | stacking unit 90, and A misregistration suppression mechanism 198 that restrains misalignment in the horizontal direction (direction intersecting the stacking direction) is provided.

  As shown in FIG. 2, four columnar support members 72 (only two are shown in FIG. 2) are provided below the laminated unit 90 to support the laminated unit 90 from below.

(Position shift suppression mechanism)
The positional shift suppression mechanism 198 is a relative displacement in the surface direction of the heat storage material layer 32, in other words, the shift in the direction intersecting the stacking direction (horizontal direction), that is, the direction intersecting the stacking direction of the filter 34 and the heat fluid portion 50. This is to suppress the misalignment. As shown in FIGS. 3 and 7 to 9, the misregistration suppressing mechanism 198 of this embodiment includes four prismatic restraining members 200 having a rectangular cross section extending in the stacking direction of the stacking unit 90. . The restraining member 200 is formed of a member having high heat resistance such as metal.

  As shown in FIG. 3, in the heat storage material layer 32, through holes 204 are formed in the vicinity of the four corners of the frame member 44 to insert the restraining member 200 in the stacking direction of the stacking unit 90. As shown, each restraining member 200 passes through the through hole 204 of each heat storage material layer 32. The restraining member 200 is inserted in the through hole 204 so as to be movable in the stacking direction.

  As shown in FIGS. 7 to 9, rectangular sandwich plates 106 are arranged on both sides of the stacking unit 90 in the stacking direction. At both ends in the longitudinal direction of the restraining member 200, screw holes (female screws) 214 into which bolts 212 penetrating holes 210 formed in the clamping plate 106 are screwed are formed. The upper end of the restraining member 200 is in contact with the lower surface of the upper sandwiching plate 106, and the bolt 212 that penetrates the hole 210 formed in the sandwiching plate 106 is screwed into the screw hole 214. It is fixed to the upper clamping plate 106.

  The lower end of the restraining member 200 is in contact with the upper surface of the lower sandwiching plate 106, and the bolt 212 that penetrates the hole 210 formed in the sandwiching plate 106 is screwed into the screw hole 214. The member 200 is fixed to the lower clamping plate 106.

  The stacking unit 90 is thus sandwiched between the pair of sandwiching plates 106 in the stacking direction. When the heat storage material molded body 40 is expanded for each member stacked in the stacking unit 90, the stacking direction interval is increased. The change is suppressed. Therefore, it is possible to suppress the occurrence of a gap between the members constituting the laminated unit 90. The interval in the stacking direction is the pitch in the stacking direction, and is the distance between the central portion of one member and the central portion of a member disposed adjacent to the one member.

  Further, since the restraining member 200 fixed to the sandwiching plate 106 passes through the through holes 204 of the heat storage material layer 32 in the stacking direction, each heat storage material layer 32 is in a direction intersecting the longitudinal direction of the restraining member 200. It is constrained so that it cannot move relative to a certain horizontal direction, in other words, a direction crossing the stacking direction.

  The reaction medium diffusion layer 36, the filter 34, and the heat flow unit 50 are sandwiched and fixed from the device width direction (arrow W direction) by the restraining members 200 arranged at the four corners of the laminated unit 90.

(Operation and effect of chemical heat storage system)
Next, the operation and effect of the chemical heat storage system 10 will be described.
When heat stored in the reactor 20 in the chemical heat storage system 10 is generated (dissipated) from the heat storage material layer 32, as shown in FIG. Is switched to the heat utilization object 96. Further, the on-off valve 19 is opened, and in this state, an intermediate temperature medium is caused to flow through the heat medium flow path 17 of the evaporation condenser 12 to evaporate the water in the liquid phase part 16B. The generated water vapor W moves in the direction of the arrow D in the communication path 14 and is supplied into the reaction vessel 22.

  Subsequently, in the reaction vessel 22, the supplied water vapor W flows through the reaction medium flow portion 26 and flows through the reaction medium diffusion layer 36. Then, when the water vapor W passes through the filter 34 and comes into contact with the heat storage material molded body 40 of the heat storage material layer 32, the heat storage material molded body 40 of the heat storage material layer 32 generates heat (dissipates heat) while causing a hydration reaction. . This heat is transported to the heat utilization object 96 by the heat medium flowing in the flow path 54 of the heat flow unit 50.

  On the other hand, when storing heat in the heat storage material molded body 40 of the heat storage material layer 32 in the chemical heat storage system 10, as shown in FIG. 94. Further, the on-off valve 19 is opened, and in this state, the heat medium heated by the heat source 94 flows into the flow path 54 of the heat flow unit 50. The heat storage material molded body 40 undergoes a dehydration reaction due to the heat of the heat medium flowing through the flow path 54, and this heat is stored in the heat storage material molded body 40.

  Further, the water vapor W separated from the heat storage material molded body 40 flows from the filter 34 into the reaction medium diffusion layer 36. The water vapor W that has flowed into the reaction medium diffusion layer 36 passes through the reaction medium flow portion 26, flows through the communication path 14 in the direction of arrow E, and flows into the evaporative condenser 12 as shown in FIG.

  Then, in the vapor phase portion 16 </ b> A of the evaporation condenser 12, the water vapor W is cooled by the refrigerant flowing through the heat medium flow path 17, and the condensed water is stored in the liquid phase portion 16 </ b> B of the container 16.

  Since the stacking unit 90 of the present embodiment is sandwiched between the pair of sandwiching plates 106, when the heat storage material molded body 40 expands, it is possible to suppress a change in the interval in the stacking direction of each member, It can suppress that the heat exchange efficiency between the thermal storage material reaction part 30 and the heat | fever fluidization part 50 falls.

  Further, in the laminated unit 90, the restraining member 200 fixed to the pair of sandwiching plates 106 passes through the through hole 204 formed in the frame member 44 of the heat storage material layer 32, and the horizontal direction of each heat storage material layer 32. Since the shift in the direction is suppressed, even if the heat storage material is pulverized, leakage of the heat storage material due to the horizontal shift of the heat storage material layer 32 is suppressed.

  Further, since the restraining member 200 is passed through the through hole 204 formed in the frame member 44, the restraining member 200 serves as a reinforcement of the frame member 44. Therefore, when the frame member 44 receives the expansion force from the heat storage material molded body 40, the horizontal deformation of the frame member 44 can be suppressed as compared with the case where the restraining member 200 is not penetrated.

  If the heat storage material leaks out of the heat storage material layer 32 and the density of the heat storage material or the amount of the heat storage material decreases, the heat exchange efficiency between the heat storage material reaction unit 30 and the heat fluidizing unit 50 may decrease. is there. However, the heat exchange efficiency between the heat storage material reaction unit 30 and the heat fluidizing unit 50 is reduced by suppressing the shift of the heat storage material layer 32 and suppressing the leakage of the heat storage material as in the present embodiment. Can be suppressed.

  Thus, in the reactor 20 of this embodiment, since it is suppressed that heat exchange efficiency falls and a heat loss can be suppressed, the chemical heat storage system 10 of this embodiment has efficient high performance. It will be a thing.

  When assembling the reactor 20 of the present embodiment, for example, the restraint member 200 is disposed and fixed on the sandwiching plate 106, and then the heat fluidizing portion 50, the heat storage material layer 32, the filter 34, and the reaction medium diffusion layer. Assembling can be easily performed by laminating 36 and finally placing the clamping plate 106 and fixing it to the restraining member 200. Further, the heat storage material layer 32 can be easily restrained so that the heat storage material layer 32 is not displaced in the horizontal direction by simply inserting the restraining member 200 into the through hole 204 of the heat storage material layer 32.

The restraining member 200 is fixed to the upper clamping plate 106 by being screwed into the upper clamping plate 106.

  The lower end of the restraining member 200 is in contact with the upper surface of the lower sandwiching plate 106, and the bolt 212 that penetrates the hole 210 formed in the sandwiching plate 106 is screwed into the screw hole 214. The member 200 is fixed to the lower clamping plate 106.

Thus, also in the laminated unit 90 of this embodiment, since the restraining member 200 fixed to the pair of sandwiching plates 106 passes through the through holes 204 of the heat storage material layer 32, each heat storage material layer 32 is , Shifting in the horizontal direction is suppressed.
In addition, about an effect | action, it is the same as that of 1st Embodiment, and even if a heat storage material is pulverized, the leakage of the heat storage material resulting from the shift | offset | difference of the heat storage material layer 32 is suppressed.

In addition, about the same member as embodiment mentioned above, the same code | symbol is attached | subjected, the description is abbreviate | omitted, and a different part from embodiment mentioned above is mainly demonstrated.

  In the misalignment suppressing mechanism 198 of the first embodiment, the restraining member 200 is arranged near the four corners of the frame member 44. However, in this embodiment, as shown in FIG. The restraining member 200 penetrates the formed through hole 204.

The restraining member 200 is fixed to the upper clamping plate 106 by being screwed into the upper clamping plate 106.

  The lower end of the restraining member 200 is in contact with the upper surface of the lower sandwiching plate 106, and the bolt 212 that penetrates the hole 210 formed in the sandwiching plate 106 is screwed into the screw hole 214. The member 200 is fixed to the lower clamping plate 106.
