Title:
CHEMICAL HEAT STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2018169071
Kind Code:
A
Abstract:
To provide a chemical heat storage device capable of improving a performance of a regeneration reaction of a reaction material.SOLUTION: A reactor 12 comprises multiple reaction materials of which the reaction temperatures are different from each other. The multiple reaction materials are disposed in such a manner that the reaction temperatures become lower as they are separated farther away from a heat transfer surface 18c with a flow channel 50. Thus, even a reaction material at a position where heat is unlikely to transfer may also speedily perform a regeneration reaction. The multiple reaction materials are disposed in such a manner that the reaction temperatures become lower and heat resistance becomes lower from an upstream side to a downstream side of a flow of a fluid FL within the flow channel 50. Thus, the heat resistance is low at the downstream side of the flow of the fluid FL, such that heat of the fluid FL is also transferred to the downstream-side reaction material without being concentrated to the upstream-side reaction material. The temperature of the downstream-side reaction material becomes lower than upstream-side reaction material but the downstream-side reaction material is capable of causing the regeneration reaction to occur since the reaction temperature is low.SELECTED DRAWING: Figure 2
