The chemical heat storage body 20 circulates between the heat storage side device B and the heat utilization side device C by the above transport of the chemical heat storage material transport means D. The chemical heat storage material transporting means D is not limited as long as it can transport the transporting pallet 31 and may be a normal transport truck or the like.

[Operation of heat transport system A described above]
First, the heat-radiated chemical heat storage body 20a (Mg (OH) ₂ ) housed in the transport pallet 31 is charged into the reactor 10 on the heat storage side device B side. Further, the inside of the reactor 10 and the inside of the condenser 6 are evacuated by the vacuum pump 7 in order to improve the reaction rate of the heat radiated chemical heat storage body 20a. The heat transfer oil 3 that has been heated by exchanging heat with the waste heat source 1 is circulated in the reactor 10 while rotating and rotating the reactor 10 when necessary. In the reactor 10, the chemical heat storage body 20 is heated by the heat supplied by the heat transfer oil 3, and the heat storage reaction (dehydration reaction) proceeds continuously.

  Water vapor generated by the dehydration reaction is cooled by the cooling water in the condenser 6 and condensed. This condensation maintains a vacuum inside the reactor 10 and inside the condenser 6. The raised cooling water is cooled again by the cooling tower 8.

  When the heat storage reaction is completed or almost completed by heating for the required time, the inside of the reactor 10 is opened to the atmosphere to break the vacuum. Then, the chemical heat storage body 20b after heat storage is taken out from the inside of the reactor 10 through the charging / unloading outlet 16, and is accommodated again in the empty transport pallet 31. Preferably, the transport pallet 31 is maintained in an airtight state in order to prevent the chemical heat storage body 20b after heat storage from absorbing moisture in the atmosphere.

  The transport pallet 31 that is airtight and contains the chemical heat storage body 20b after heat storage is transferred from the heat storage side heat storage body transport means 30a to the transport truck 40, which is an example of the chemical heat storage body transport means D, by a lift or the like (not shown). To load. Then, the transport pallet 31 is transported to the heat utilization side device C by the transport truck 40.

  There are no distance and time restrictions on the transportation of the transportation pallet 31 by the transportation truck 40. In the case where the heat storage side device B and the heat utilization side device C are installed in an independent state in a close place, it becomes easy to effectively cope with the time gap of heat demand. In addition, when installed in a place far away, it is possible to effectively deal with both temporal and spatial gaps in heat demand.

  The transport truck 40 loaded with the transport pallet 31 travels to the heat utilization side device C, and uses the heat utilization side heat storage material transport device 30b to transfer the chemical heat storage body 20b after heat storage from the transport pallet 31 to the inside of the reaction vessel 50. throw into. On the other hand, pure water is fed into the evaporator 61 from the pure water device 62, and the inside of the reactor 50 and the evaporator 61 is evacuated by a vacuum pump 63 in order to improve the reaction rate of the chemical heat storage body 20b after heat storage. (Low pressure). In the illustrated example, a part of the steam generated in the heat exchanger 66 is supplied to the evaporator 61 as latent heat of evaporation by appropriate means, and the generated steam is supplied to the inside of the reactor 50.

  The rotation roller 17 is driven, and if necessary, the oscillating table 18 is also driven to rotate the reactor 50 and, if necessary, to oscillate the water vapor supplied inside the reactor 50. The chemical heat storage body 20b after heat storage is positively mixed. Thereby, the exothermic reaction (hydrolysis) of both proceeds continuously to generate heat. The heat generated inside the reactor 50 is recovered as sensible heat by the heat transfer oil 64. The heated heat medium oil 64 is circulated between the heat utilization side heat exchanger 66 by the heat medium oil circulation pump 65. When the heat exchanger 66 on the heat utilization side is a steam boiler as shown in the figure, the generated steam can be effectively utilized by supplying it to the steam utilization facility.

  When the heat release reaction is completed or almost completed by supplying water for a predetermined time, the inside of the reactor 50 is opened to the atmosphere and the vacuum is broken. Then, the heat radiated chemical heat storage body 20a is taken out from the inside of the reactor 50 through the charging / discharging outlet 16, and is accommodated again in the empty transport pallet 31. Here again, the transport pallet 31 is preferably maintained in an airtight state in order to prevent the radiated chemical heat storage body 20a from absorbing moisture in the atmosphere.

  The transport pallet 31 containing the heat-dissipated chemical heat storage body 20b and hermetically sealed is loaded on the transport truck 40 from the heat utilization side heat storage body transport means 30b by a lift (not shown) and returned to the heat storage side apparatus B by the transport truck 40. . On the heat storage side device B side, the transport pallet 31 is lowered from the transport truck 40 to the heat storage side heat storage material transfer device 30a by a lift or the like, and the heat-radiated chemical heat storage material 20a is again put into the reactor 10 of the heat storage side device B when appropriate. throw into.

  By using the heat transport system according to the present invention as described above and repeating the above procedure, the heat is temporally transferred from the heat storage side to the heat utilization side using a chemical heat storage body that repeatedly stores and releases heat by a reversible reaction.・ Effective transportation is possible with the spatial gap eliminated. Moreover, only the chemical heat storage body 20 is transported from the heat storage side to the heat utilization side, the heat storage density during transportation on the transportation pallet 31 is greatly improved, and the transportation cost per unit heat quantity is greatly reduced.

[Other embodiments]
[Other Embodiments as Apparatus]
In FIG. 2, the reactor 10 (50) has a double shell structure, and has a heat medium passage 11 for circulating the heat medium oil 3 between the inner shell 10a and the outer shell 10b, and the inner shell 10a. The structure of the reactor 10 (50) according to the present invention includes means for stirring and flowing the chemical heat storage body 20 inside the reactor. Other configurations may be used on the condition.

  For example, it is not a double shell structure, and although not shown, an appropriate number of tube-shaped heat medium (heat medium oil 3) flow paths 11 are accommodated in a shell that accommodates the chemical heat storage body 20 and is preferably rotatable. The thing of the structure arrange | positioned may be sufficient. In the case of the reactor 10, the chemical heat storage body 20 (20 a) accommodated in the shell is stirred and fluidized, and in the case of the reactor 10, the chemical heat storage body 20 is heated by the heat supplied by the heat transfer oil 3 and the heat storage reaction ( The dehydration reaction) proceeds effectively and continuously. In the case of the reactor 50, the chemical heat storage body 20 (20b) accommodated in the shell and the supplied water vapor are positively mixed together. The exothermic reaction (hydrolysis) proceeds effectively and continuously. The generated heat is recovered by a heat medium (heat medium oil 64) flowing in the tube.

  Moreover, even if it is a case of a double shell structure, the structure which arrange | positions a heat carrier inside and a chemical heat storage body may be sufficient. Further, in the heat storage side device B, heating by electric power can be used as a heating source of the reactor 10. In that case, in order to increase thermal efficiency, it is desirable that the power heater and the chemical heat storage body be in direct contact with each other.

  The stirring method of the chemical heat storage body 20 in the reactor 10 (50) is not limited to the rotary type or the swing type as shown in FIG. 2, but as shown in FIG. A vibration motor 70 is attached to (50) to give vibration to the reactor, whereby the internal chemical heat storage body 20 is flowed and stirred. Moreover, as shown in FIG.3 (b), the chemical heat storage body 20 accommodated in the inside is arrange | positioned by arrange | positioning the stirring member 71 like a stirring rod, a blade | wing, and a screw body inside, and rotating it with the motor 72. It may be in the form of flowing and stirring.

  Furthermore, the reason why the inside of the reactor 10 (50) is evacuated is to improve the reaction rate. However, the desired reaction rate can be obtained without using a vacuum (low pressure) due to the type of the chemical heat storage body 20 or the like. Can be achieved even under atmospheric pressure and pressure without applying a vacuum. The material of the reactor 10 (50) is preferably SUS, but any material can be used as long as it has the necessary strength and corrosion resistance.

  Further, in the example shown in FIG. 1, in the heat storage side apparatus B, the example in which the waste heat from the waste heat source 1 is recovered using the heat exchanger 2 has been described. However, the waste heat is directly introduced into the reactor 10. It may be a system to do. The heat source is not limited to waste heat, and natural energy such as solar heat or geothermal heat may be used. As described above, heating by electric power is also possible. The use of the condenser 6 is not essential, and when the reaction temperature is high and a vapor pressure higher than the atmospheric pressure is generated, the atmosphere can be opened to the atmosphere. As for the cooling method, use of the cooling tower 8 is merely an example, and air cooling, cooling with a chiller, cooling with groundwater, or the like can also be used.

  The method of transporting the chemical heat storage body 20 is also exemplified by the use of the transport pallet 31. Depending on the type of the chemical heat storage body 20, etc., it can be bulk-loaded on a lorry or a closed truck. Even when the transport pallet 31 is used, it is also possible to use a material that does not have an airtight function depending on the reactivity of the chemical heat storage body.

  In the example shown in FIG. 1, although the example using the pure water apparatus 62 was shown in the heat utilization side apparatus C, industrial water and drinking water can also be used. When the desired reaction rate can be obtained from the relationship of the type of the chemical heat storage body 20, etc., it is not essential to evacuate the reactor 50, and it may be under atmospheric pressure or under pressure. The evaporator 61 is not essential, and the intended purpose can be achieved even by direct spraying of steam from another boiler or direct spraying of water, for example. The heat recovery method may be a method of directly introducing an object to be heated into the reactor 50 instead of the method of circulating the heat transfer oil 64 in the reactor 50 as described with reference to FIG. The heat exchanger 66 is not limited to a steam boiler, and various conventionally known heat exchangers such as a plate heat exchanger and a shell and tube heat exchanger as described above can be used. In addition, the use of the transport pallet 31 is also an example on the heat utilization side device C side, and depending on the type of the chemical heat storage body 20 or the like, it can be stacked on a lorry or a sealed truck. Even when the transporting pallet 31 is used, it is possible to use one having no airtight function depending on the reactivity of the chemical heat storage body.
