Description

本発明は、熱発生部の熱を蓄熱可能、且つ、当該蓄熱した熱を熱需要部に放熱可能な可搬式の熱搬送ユニットを備えた熱搬送システム、及び、当該熱搬送システムに利用される熱搬送ユニット、並びに、当該熱搬送ユニットを利用して前記熱発生部の熱を前記熱需要部に搬送する熱搬送方法に関する。   INDUSTRIAL APPLICABILITY The present invention is used for a heat transfer system including a portable heat transfer unit capable of storing heat of a heat generation unit and dissipating the stored heat to a heat demand unit, and the heat transfer system. The present invention relates to a heat transfer unit and a heat transfer method for transferring heat of the heat generation unit to the heat demand unit using the heat transfer unit.

ごみ焼却場、発電所、製鉄所などの施設で発生した高温の排熱は、例えばその施設に設置された発電用蒸気タービンを駆動するための高温蒸気として、現地において有効利用される。しかし、蒸気タービンを駆動した後に排出される１５０℃程度の低温蒸気などのように、比較的低温の排熱については、施設内又はその周辺での使い道が少なく、多くの場合には余剰として廃棄されてしまう。そして、近年、省エネルギ及び省資源の面で、このような余剰排熱についても有効利用することがすることが求められている。   High-temperature exhaust heat generated in facilities such as a garbage incineration plant, a power plant, and a steel mill is effectively used locally as, for example, high-temperature steam for driving a power generation steam turbine installed in the facility. However, relatively low-temperature exhaust heat, such as low-temperature steam of about 150 ° C that is exhausted after driving the steam turbine, has little use in and around the facility and is often discarded as surplus Will be. In recent years, there is a demand for effective use of such excess exhaust heat in terms of energy saving and resource saving.

余剰排熱を有効利用する技術の一つとして、トレーラなどに搭載されて蓄熱・放熱を交互に繰り返すことができる可搬式の熱搬送ユニットを利用して、ごみ焼却場などの熱発生部の熱を当該熱発生部から離れた各家庭や商業施設などの熱需要部に搬送して有効利用するというような熱搬送技術の開発が進められている。そして、従来の熱搬送ユニットとして、最も一般的に利用されている潜熱蓄熱材を用いたもの（例えば特許文献１を参照。）の他、ケミカルヒートポンプを利用した所謂ケミカルヒートポンプコンテナが知られている（例えば、特許文献２を参照。）。   As one of the technologies to effectively use surplus waste heat, heat from heat generating parts such as garbage incinerators is installed using a portable heat transfer unit that is mounted on a trailer and can alternately store and release heat. Development of a heat transfer technology is underway, in which the heat is transferred to a heat demanding part of each household or commercial facility away from the heat generating part for effective use. As a conventional heat transfer unit, a so-called chemical heat pump container using a chemical heat pump is known in addition to one using the most commonly used latent heat storage material (see, for example, Patent Document 1). (For example, see Patent Document 2).

従来のケミカルヒートポンプコンテナは、吸熱を伴う脱水反応と発熱を伴う水和反応とを可逆的に行う反応材を内部に収容してなる反応器を備えると共に、その反応器に対して、ガス通路及びそのガス通路に設けた遮断弁を介して連通され、当該ガス通路を通じて水蒸気の授受を行う蒸発凝縮器を備える。更に、反応器には、反応材と熱媒流体（特許文献１における「高温流体」）との間で熱交換を行う反応器用熱交換部が設けられており、一方、蒸発凝縮器には、蒸発凝縮器の内部を冷却水や加熱水（特許文献１における「低温流体」）との熱交換により加熱又は冷却する蒸発凝縮器用熱交換部が設けられている。
即ち、この種のケミカルヒートポンプコンテナは、反応器と蒸発凝縮器との両方が設置されており、更に、外部に対する接続部として、反応器に配置された反応器用熱交換部に対して熱媒流体の授受を行うための一対の熱媒流体用接続部と、蒸発凝縮器に配置された蒸発凝縮器用熱交換部に対して冷却水や加熱水等の低温流体の授受を行うための一対の低温流体用接続部とが必要となる。 A conventional chemical heat pump container includes a reactor containing therein a reaction material that reversibly performs a dehydration reaction with endotherm and a hydration reaction with exotherm, and a gas passage and An evaporative condenser is provided that communicates via a shut-off valve provided in the gas passage and transfers water vapor through the gas passage. Furthermore, the reactor is provided with a heat exchanger for the reactor that performs heat exchange between the reaction material and the heat transfer fluid (“high temperature fluid” in Patent Document 1), while the evaporation condenser includes There is provided an evaporative condenser heat exchange section that heats or cools the interior of the evaporative condenser by heat exchange with cooling water or heating water (“low temperature fluid” in Patent Document 1).
That is, this type of chemical heat pump container is provided with both a reactor and an evaporative condenser, and further, as a connection part to the outside, a heat transfer fluid to a heat exchange part for the reactor arranged in the reactor. A pair of low-temperature fluids for transferring and receiving low-temperature fluid such as cooling water and heating water to a pair of heating medium fluid connection parts for transferring and receiving and a heat exchanger for evaporating condensers arranged in the evaporating condenser A fluid connection is required.

このように構成されたケミカルヒートポンプコンテナを利用した熱搬送方法によれば、以下に示すような蓄熱操作及び放熱操作が行われることになる。
即ち、熱発生部側で行われる蓄熱操作では、反応器用熱交換部との間で循環させる熱媒流体を介して反応材に熱を与えながら、遮断弁を開放して反応器と蒸発凝縮器とを連通状態とし、更に、蒸発凝縮器用熱交換部との間で冷却水を循環させる。すると、反応器において、反応材が吸熱を伴う脱水反応を行う形態で熱を蓄えることになり、当該脱水反応により発生した水蒸気がガス通路を通じて蒸発凝縮器側に送られる。そして、蒸発凝縮器において、その水蒸気が冷却・凝縮されて凝縮水として蓄えられることになる。尚、この熱発生部側での蓄熱操作では、高温の熱を反応材に与えて反応器に当該熱を蓄熱することの他、反応器の内圧を低くして比較的低温の熱を反応材に与える形態で熱発生部側において冷熱生成を行うこともできる。
また、この蓄熱操作が完了すると、遮断弁が遮断されることで反応材の脱水状態が維持され、その状態で熱需要部に搬送される。
一方、熱需要部で行われる放熱操作では、反応器用熱交換部との間で循環させる熱媒流体を介して反応材から熱を回収しながら、遮断弁を開放して反応器と蒸発凝縮器とを連通状態とし、更に、蒸発凝縮器用熱交換部との間で加熱水を循環させる。すると、蒸発凝縮器において、凝縮水が加熱されて蒸発することで、水蒸気が発生し、その水蒸気がガス通路を通じて反応器側に送られる。そして、反応器において、その水蒸気を利用して、反応材が発熱を伴う水和反応を行う形態で熱を放出することになる。 According to the heat transfer method using the chemical heat pump container configured as described above, a heat storage operation and a heat dissipation operation as described below are performed.
That is, in the heat storage operation performed on the heat generating unit side, the reactor and the evaporation condenser are opened by opening the shut-off valve while supplying heat to the reaction material via the heat transfer fluid circulated with the heat exchange unit for the reactor. And the cooling water is circulated between the heat exchanger for the evaporative condenser. Then, in the reactor, heat is stored in a form in which the reaction material performs a dehydration reaction accompanied by endotherm, and water vapor generated by the dehydration reaction is sent to the evaporation condenser side through the gas passage. Then, in the evaporative condenser, the water vapor is cooled and condensed and stored as condensed water. In this heat storage operation on the heat generating part side, in addition to applying high temperature heat to the reaction material to store the heat in the reactor, the internal pressure of the reactor is lowered to generate relatively low temperature heat. Cold heat generation can also be performed on the heat generating unit side in the form given to the above.
Moreover, when this heat storage operation is completed, the dewatering state of the reaction material is maintained by shutting off the shutoff valve, and in this state, the reaction material is conveyed to the heat demand section.
On the other hand, in the heat radiation operation performed in the heat demand section, while recovering heat from the reaction material via the heat transfer fluid circulated between the heat exchange section for the reactor, the shutoff valve is opened and the reactor and the evaporation condenser are recovered. And the heated water is circulated with the heat exchanger for the evaporative condenser. Then, in the evaporative condenser, the condensed water is heated and evaporated to generate water vapor, and the water vapor is sent to the reactor side through the gas passage. And in a reactor, using the water vapor | steam, a reaction material will discharge | release heat in the form which performs the hydration reaction accompanied by heat_generation | fever.

しかしながら、上記従来の熱搬送ユニットを利用した熱搬送方法では、コンテナに反応器と蒸発凝縮器との両方を設置する必要があるため、蓄熱容量あたりの外形寸法が比較的大きくなっていた。また、蓄熱操作が完了した後に熱発生部から熱需要部まで搬送する際においては、蒸発凝縮器には比較的多量の水が蓄えられていることになるため、蓄熱容量あたりの重量が比較的大きくなっていた。即ち、従来の熱搬送ユニットでは、外形寸法及び重量の面で課題が存在しており、熱搬送による省エネルギ及び省資源の効果を充分に享受することができなかった。   However, in the heat transfer method using the above conventional heat transfer unit, both the reactor and the evaporative condenser need to be installed in the container, so that the outer dimensions per heat storage capacity are relatively large. In addition, when transporting from the heat generation unit to the heat demand unit after the heat storage operation is completed, a relatively large amount of water is stored in the evaporative condenser, so the weight per heat storage capacity is relatively low. It was getting bigger. That is, in the conventional heat transfer unit, there are problems in terms of external dimensions and weight, and the effects of energy saving and resource saving by heat transfer cannot be fully enjoyed.

本発明は、かかる点に着目してなされたものであり、その目的は、熱搬送ユニットのコンパクト化且つ軽量化を実現して多くの熱を搬送して省エネルギ及び省資源の効果を充分に享受できる熱搬送技術を提供する点にある。   The present invention has been made paying attention to such a point, and its purpose is to realize a compact and lightweight heat transfer unit to transfer a large amount of heat and sufficiently achieve energy saving and resource saving effects. It is in providing heat transfer technology that can be enjoyed.

上記目的を達成するための本発明に係る熱搬送システムは、
熱発生部の熱を蓄熱可能、且つ、当該蓄熱した熱を熱需要部に放熱可能な可搬式の熱搬送ユニットを備えた熱搬送システムであって、
その第１特徴構成は、
前記熱搬送ユニットに、吸熱を伴う脱水反応と発熱を伴う水和反応とを可逆的に行う反応材を内部に収容してなる反応器を設け、
前記熱発生部に、前記反応材に熱を与える与熱手段と、前記反応器から水蒸気を吸引するガス吸引手段とを設け、
前記熱需要部に、前記反応材から熱を回収する熱回収手段と、前記反応器に水蒸気を供給する水蒸気供給手段とを設けてなる点にある。 In order to achieve the above object, a heat transfer system according to the present invention comprises:
A heat transfer system including a portable heat transfer unit capable of storing heat of the heat generation unit and capable of radiating the stored heat to the heat demand unit,
The first characteristic configuration is
The heat transfer unit is provided with a reactor containing therein a reaction material that reversibly performs a dehydration reaction with endotherm and a hydration reaction with heat generation,
The heat generating unit is provided with heating means for applying heat to the reaction material, and gas suction means for sucking water vapor from the reactor,
The heat demand section is provided with a heat recovery means for recovering heat from the reaction material and a steam supply means for supplying steam to the reactor.

上記熱搬送システムの第１特徴構成によれば、熱発生部にガス吸引手段が設けられている共に熱需要部に水蒸気供給手段が設けられているので、熱搬送ユニットに蒸発凝縮器を設ける必要がなく、熱搬送ユニット側の反応材に吸熱を伴う脱水反応をさせて熱発生部の熱を熱搬送ユニット側の反応器へ蓄える蓄熱操作と、熱搬送ユニット側の反応材に発熱を伴う水和反応をさせて反応器に蓄えた熱を熱需要部側へ放出する放熱操作とを実行する形態で、熱発生部から熱需要部へ熱を搬送することができる。
即ち、熱発生部においては、与熱手段を作動させて反応材に熱を与えながら吸引手段を作動させて反応器からガスとしての水蒸気を吸引する形態で、上記蓄熱操作を実行することができる。
一方、熱需要部においては、熱回収手段を作動させて反応材から熱を回収しながら供給手段を作動させて反応器に水蒸気を供給する形態で、上記放熱操作を実行することができる。
よって、熱搬送ユニットは、蒸発凝縮器を省略することで、蓄熱容量あたりの外形寸法を比較的小さくでき、更には、蓄熱操作において反応材の脱水反応により発生した水蒸気は、凝縮水として熱搬送ユニットに蓄えるのではなく熱発生部側に排出するので、蓄熱容量あたりの重量を比較的小さくできる。
従って、本発明の熱搬送システムにより、熱搬送ユニットのコンパクト化且つ軽量化を実現して多くの熱を搬送して省エネルギ及び省資源の効果を充分に享受できる熱搬送技術を提供することができる。 According to the first characteristic configuration of the heat transfer system, the heat generating unit is provided with the gas suction unit, and the heat demanding unit is provided with the water vapor supply unit. Therefore, it is necessary to provide the evaporative condenser in the heat transfer unit. Heat storage operation that causes the reaction material on the heat transfer unit side to perform a dehydration reaction with endotherm and stores the heat of the heat generation unit in the reactor on the heat transfer unit side, and water that generates heat on the reaction material on the heat transfer unit side Heat can be transported from the heat generating part to the heat demanding part in a form in which a heat radiation operation is performed to release the heat stored in the reactor to the heat demanding part side through a sum reaction.
That is, in the heat generation unit, the heat storage operation can be performed in a form in which the suction unit is operated while operating the heating unit to apply heat to the reaction material to suck the water vapor as the gas from the reactor. .
On the other hand, in the heat demand section, the heat radiation operation can be performed in such a form that the steam is supplied to the reactor by operating the supply means while operating the heat recovery means to recover heat from the reaction material.
Therefore, by omitting the evaporative condenser, the heat transfer unit can make the outer dimensions per heat storage capacity relatively small, and further, the water vapor generated by the dehydration reaction of the reaction material in the heat storage operation is heat transferred as condensed water. Since the heat is not stored in the unit but is discharged to the heat generating part, the weight per heat storage capacity can be made relatively small.
Therefore, by the heat transfer system of the present invention, it is possible to provide a heat transfer technology that can realize a compact and lightweight heat transfer unit to transfer a large amount of heat and fully enjoy the effects of energy saving and resource saving. it can.

上記熱搬送システムの第２特徴構成によれば、熱発生部での蓄熱操作において、与熱手段は、反応器に配置された反応器用熱交換部に接続された状態で、熱発生部側で熱を与えて加熱した熱媒流体を反応器用熱交換部に供給しながら、同反応器用熱交換部において反応材の脱水反応による吸熱作用により冷却された熱媒流体を熱発生部側に取り出すという合理的な構成で、熱発生部側の熱を熱搬送ユニットの反応器の反応材に与えることができる。
一方、熱需要部での放熱操作において、熱回収手段は、反応器に配置された反応器用熱交換部に接続された状態で、反応器用熱交換部で反応材の水和反応による発熱作用により加熱された熱媒流体を熱需要部側に取り出しながら、熱需要部側で冷却した熱媒流体を反応器用熱交換部に供給するという合理的な構成で、熱搬送ユニットの反応器の反応材から熱を回収することができる。 According to the second characteristic configuration of the heat transfer system, in the heat storage operation at the heat generation unit, the heating means is connected to the heat exchange unit for the reactor disposed in the reactor, and on the heat generation unit side. While supplying the heat transfer fluid heated by supplying heat to the heat exchange section for the reactor, the heat transfer fluid cooled by the endothermic action by the dehydration reaction of the reaction material in the heat exchange section for the reactor is taken out to the heat generation section side. With a rational configuration, heat on the heat generating unit side can be applied to the reaction material of the reactor of the heat transfer unit.
On the other hand, in the heat radiation operation in the heat demand section, the heat recovery means is connected to the heat exchange section for the reactor arranged in the reactor, and generates heat due to the hydration reaction of the reaction material in the reactor heat exchange section. With the rational configuration of supplying the heat transfer fluid cooled on the heat demand section side to the heat exchange section for the reactor while taking out the heated heat transfer fluid to the heat demand section side, the reaction material of the reactor of the heat transfer unit Heat can be recovered.

本発明に係る熱搬送システムの第３特徴構成は、上記第１乃至第２特徴構成の何れかに加えて、
前記熱発生部に設けた前記ガス吸引手段が、前記反応器に連通するガス通路に接続可能に配置され、前記ガス通路を通じて前記反応器から前記水蒸気を吸引して外部に排出するガス吸引ポンプで構成されている点にある。 In addition to any of the first to second feature configurations described above, the third feature configuration of the heat transfer system according to the present invention includes:
A gas suction pump, wherein the gas suction means provided in the heat generation unit is arranged to be connectable to a gas passage communicating with the reactor, and sucks the water vapor from the reactor through the gas passage and discharges it to the outside; It is in the point which is comprised.

上記熱搬送システムの第３特徴構成によれば、熱発生部での蓄熱操作において、熱搬送ユニット側の反応器からガスを吸引するガス吸引手段を、上記ガス吸引ポンプで構成することができる。即ち、熱発生部での蓄熱操作において、上記ガス吸引ポンプを反応器に接続した状態で作動させることで、常時反応器から水蒸気等のガスを吸引して反応器の内圧を低く維持し、反応材の脱水反応を継続させることができる。   According to the 3rd characteristic structure of the said heat transfer system, the gas suction means which attracts | sucks gas from the reactor by the side of a heat transfer unit in the heat storage operation in a heat generation part can be comprised with the said gas suction pump. That is, in the heat storage operation in the heat generation part, by operating the gas suction pump connected to the reactor, gas such as water vapor is constantly sucked from the reactor to keep the internal pressure of the reactor low, and the reaction The dehydration reaction of the material can be continued.

Heat for the condenser that cools the inside of the condenser by heat exchange between the condenser disposed so as to be connectable to a gas passage communicating with the reactor and the cooling water by the gas suction means provided in the heat generation unit. It is in the point comprised by the exchange part and the suction pump for condensers which can discharge | emit the water accumulated in the said condenser, and can pressure-reduce the said condenser.

上記熱搬送システムの第４特徴構成によれば、熱発生部での蓄熱操作において熱搬送ユニット側の反応器からガスを吸引するガス吸引手段を、上記凝縮器、上記凝縮器用熱交換部、並びに、上記凝縮器用吸引ポンプで構成することができる。即ち、熱発生部での蓄熱操作において、先ず、凝縮器に溜まっている水を排出した状態で、凝縮器用吸引ポンプを作動させることで、凝縮器を減圧することができる。次に、そのように減圧された凝縮器を熱搬送ユニット側の反応器に接続した状態で、凝縮器用熱交換部に冷却水を通流させることで、凝縮器並びに反応器の内圧を低く維持しながら、水蒸気等のガスを反応器から凝縮器へ向けて通流させることができるので、凝縮器における水蒸気の凝縮を伴って反応材の脱水反応を継続させることができる。   According to the fourth characteristic configuration of the heat transfer system, the gas suction means for sucking gas from the reactor on the heat transfer unit side in the heat storage operation in the heat generation unit includes the condenser, the heat exchanger for the condenser, and The condenser suction pump can be used. That is, in the heat storage operation in the heat generating unit, first, the condenser can be decompressed by operating the condenser suction pump in a state where the water accumulated in the condenser is discharged. Next, with the condenser thus depressurized connected to the reactor on the heat transfer unit side, the cooling water is passed through the heat exchanger for the condenser to keep the internal pressure of the condenser and the reactor low. However, since a gas such as water vapor can flow from the reactor toward the condenser, the dehydration reaction of the reaction material can be continued with the condensation of water vapor in the condenser.

本発明に係る熱搬送システムの第５特徴構成は、上記第１乃至第４特徴構成の何れかに加えて、
前記熱需要部に設けた前記水蒸気供給手段が、前記反応器に連通するガス通路に接続可能に配置された蒸発器と、前記蒸発器の内部を加熱水との熱交換により加熱する蒸発器用熱交換部と、前記蒸発器に給水可能な給水部とで構成されている点にある。 In addition to any of the first to fourth feature configurations described above, the fifth feature configuration of the heat transfer system according to the present invention includes:

また、このような構成において、蒸発器並びに反応器の内圧を低くするほど、蒸発器用熱交換部に通流させる加熱水の温度を低くすることができ、例えば、加熱水として常温の水道水を利用した場合でも、低圧の蒸発器においてその加熱水との熱交換により水を加熱して水蒸気を発生させることができる。 According to the fifth characteristic configuration of the heat transfer system, the water vapor supply means for supplying the vapor to the reactor on the heat transfer unit side in the heat radiation operation in the heat demand unit includes the evaporator, the heat exchanger for the evaporator, It can comprise with a water supply part and the said suction pump for evaporators. That is, in the heat radiation operation in the heat demand section, first, water can be supplied to the evaporator by the water supply section, and water can be stored in the evaporator. Next, in such a state that the evaporator in which water is stored is connected to the reactor, the heating water is allowed to flow through the evaporator heat exchanging portion, while maintaining the internal pressure of the evaporator and the reactor low, Since water vapor can flow from the evaporator to the reactor, the hydration reaction of the reactant can be continued with evaporation of the water in the evaporator.
Further, in such a configuration, the lower the internal pressure of the evaporator and the reactor, the lower the temperature of the heated water flowing through the heat exchanger for the evaporator, for example, normal temperature tap water can be used as the heated water. Even when it is used, it is possible to generate water vapor by heating water by heat exchange with the heated water in a low-pressure evaporator.

The gas sucked by the gas suction pump B11 is exhausted after being appropriately treated.

〔蓄熱操作〕
このような熱発生部Ｂにおいては、与熱手段Ｂ２を作動させて熱搬送ユニットＡ側の反応材Ａ２に熱を与えながら、ガス吸引手段Ｂ１を作動させて熱搬送ユニットＡ側の反応器Ａ１からガスとしての水蒸気Ｓを吸引して、反応材Ａ２に脱水反応をさせる形態で、熱発生部Ｂの熱を熱搬送ユニットＡ側に蓄熱する蓄熱操作を実行することができ、その詳細について以下に説明する。 [Heat storage operation]
In such a heat generating part B, the gas suction means B1 is operated while the heating means B2 is operated to apply heat to the reaction material A2 on the heat transfer unit A side, and the reactor A1 on the heat transfer unit A side. The heat storage operation of storing the heat of the heat generation part B on the heat transfer unit A side can be executed in a form in which the water vapor S as a gas is sucked from the reaction material to cause the reaction material A2 to perform a dehydration reaction. Explained.

熱発生部Ｂにおいて蓄熱操作を実行するにあたり、先ず、反応材Ａ２が後述する放熱操作における水和反応後の水和状態である熱搬送ユニットＡを搭載したトレーラＴを準備し、熱搬送ユニットＡ側の熱媒接続部Ａ９と熱発生部Ｂ側の熱媒接続部Ｂ９とを接続して夫々の熱媒遮断弁Ａ８，Ｂ８を開放し、更に、熱搬送ユニットＡ側のガス接続部Ａ７と熱発生部Ｂ側のガス接続部Ｂ７とを接続して夫々のガス遮断弁Ａ６，Ｂ６を開放する。   In performing the heat storage operation in the heat generating part B, first, the reaction material A2 is prepared with a trailer T equipped with the heat transfer unit A which is a hydrated state after the hydration reaction in the heat release operation described later, and the heat transfer unit A Side heat medium connection part A9 and heat generation part B side heat medium connection part B9 are connected to open the respective heat medium shutoff valves A8, B8, and further, the gas connection part A7 on the heat transfer unit A side and The gas shutoff valves A6 and B6 are opened by connecting the gas connection part B7 on the heat generating part B side.

次に、上記ガス吸引ポンプＢ１１による熱搬送ユニットＡ側の反応器Ａ１からのガスの吸引を開始し、当該反応器Ａ１の内圧が例えば５ｋＰａに低下した時点で、上記循環ポンプＢ２２による熱搬送ユニットＡ側の反応器用熱交換器Ａ３への熱媒流体ＦＡ１の循環を開始すると共に、加熱用熱交換器Ｂ２１への比較的高温の加熱媒体ＦＢ１の供給を開始して熱媒流体ＦＡ１の加熱を開始する。
ここで、熱搬送ユニットＡ側の反応器Ａ１の内圧に相当する一時側圧力が例えば５ｋＰａ程度に維持されるようにガス吸引ポンプＢ１１の出力が制御され、一方、熱搬送ユニットＡ側の反応器用熱交換器Ａ３へ供給される熱媒流体ＦＡ１の温度が例えば１２０℃程度に維持されるように加熱用熱交換器Ｂ２１への加熱媒体ＦＢ１の供給量が制御される。 Next, suction of gas from the reactor A1 on the heat transfer unit A side by the gas suction pump B11 is started, and when the internal pressure of the reactor A1 decreases to, for example, 5 kPa, the heat transfer unit by the circulation pump B22 Circulation of the heating medium fluid FA1 to the A-side reactor heat exchanger A3 is started, and supply of a relatively high-temperature heating medium FB1 to the heating heat exchanger B21 is started to heat the heating medium fluid FA1.

Here, the output of the gas suction pump B11 is controlled so that the temporary pressure corresponding to the internal pressure of the reactor A1 on the heat transfer unit A side is maintained at, for example, about 5 kPa. The supply amount of the heating medium FB1 to the heating heat exchanger B21 is controlled so that the temperature of the heating medium fluid FA1 supplied to the heat exchanger A3 is maintained at about 120 ° C., for example.

そして、上記のような蓄熱操作を実行することで、熱搬送ユニットＡ側の反応器Ａ１においては、反応材Ａ２が反応器用熱交換器Ａ３における熱媒流体ＦＡ１との熱交換により加熱されながら、反応器Ａ１の内圧が常に低く維持されることになる。
すると、反応材Ａ２は、以下の化学反応式（１）で示されるように、下記ΔＨに相当する吸熱を伴う脱水反応を行う形態で、熱発生部Ｂ側の熱を蓄えることになり、この脱水反応により発生した水蒸気Ｓが、ガス吸引ポンプＢ１１により熱発生部Ｂ側に吸引されて排出されることになる。 Then, by performing the heat storage operation as described above, in the reactor A1 on the heat transfer unit A side, the reaction material A2 is heated by heat exchange with the heat transfer fluid FA1 in the reactor heat exchanger A3, The internal pressure of the reactor A1 is always kept low.
Then, as shown in the following chemical reaction formula (1), the reaction material A2 stores heat on the heat generation part B side in a form of performing a dehydration reaction with endotherm corresponding to the following ΔH. The water vapor S generated by the dehydration reaction is sucked and discharged to the heat generating part B side by the gas suction pump B11.

ＣａＣｌ2・４Ｈ2Ｏ＋ΔＨ→ＣａＣｌ2・Ｈ2Ｏ＋３Ｈ2Ｏ（ｇａｓ）・・・（１） CaCl 2 · 4H 2 O + ΔH → CaCl 2 · H 2 O + 3H 2 O (gas) (1)

上記のような蓄熱操作を実行した後には、夫々の熱媒遮断弁Ａ８，Ｂ８を遮断して熱搬送ユニットＡ側の熱媒接続部Ａ９と熱発生部Ｂ側の熱媒接続部Ｂ９との接続を解除し、更に、夫々のガス遮断弁Ａ６，Ｂ６を遮断して熱搬送ユニットＡ側のガス接続部Ａ７と熱発生部Ｂ側のガス接続部Ｂ７との接続を解除する。そして、このように反応材Ａ２が脱水反応後の脱水状態となった熱搬送ユニットＡは、トレーラＴに搭載されて、後述する熱需要部Ｃに搬送されることになる。   After performing the heat storage operation as described above, the respective heat medium shutoff valves A8 and B8 are shut off, and the heat medium connecting part A9 on the heat transfer unit A side and the heat medium connecting part B9 on the heat generating part B side are connected. The connection is released, and the gas shutoff valves A6 and B6 are shut off to release the connection between the gas connection part A7 on the heat transfer unit A side and the gas connection part B7 on the heat generation part B side. Then, the heat transfer unit A in which the reaction material A2 is in the dehydrated state after the dehydration reaction is mounted on the trailer T and is transferred to the heat demand unit C described later.

先ず、給水弁Ｃ１３を開放して蒸発器Ｃ１１の内部に給水ＦＣ３を供給して、蒸発器Ｃ１１の内部に給水ＦＣ３を貯留させる。次に、ガス遮断弁Ｃ６を開放すると、熱搬送ユニットＡ側の反応器Ａ１の内圧が予め低い状態であることから、蒸発器Ｃ１１の内圧も比較的低くなって、蒸発器Ｃ１１での水の沸点が比較的低くなる。そして、蒸発器用熱交換器Ｃ１２に加熱水ＦＣ１を通流させることで、蒸発器Ｃ１１に貯留する給水ＦＣ３が加熱されて沸騰し、その沸騰により生成された水蒸気Ｓがガス通路Ａ５を通じて反応器Ａ１に供給されることになる。また、上記ガス遮断弁Ｃ６を開放する前に、蒸発器用吸引ポンプＣ１４を作動させて予め蒸発器Ｃ１１を減圧するようにすれば、ガス遮断弁Ｃ６を開放した後においても、蒸発器Ｃ１１及び反応器Ａ１の内圧をより低く保つことができるので、蒸発器Ｃ１１における給水ＦＣ３の沸騰を促進させて、より多くの水蒸気Ｓを熱搬送ユニットＡ側の反応器Ａ１に供給することができる。 By operating the steam supply means C1 configured as described above, the steam S can be supplied to the reactor A1 on the heat transfer unit A side. The details of the operation procedure will be described below. .
First, the water supply valve C13 is opened, the water supply FC3 is supplied to the inside of the evaporator C11, and the water supply FC3 is stored inside the evaporator C11. Next, when the gas shut-off valve C6 is opened, since the internal pressure of the reactor A1 on the heat transfer unit A side is in a low state in advance, the internal pressure of the evaporator C11 also becomes relatively low, and the water in the evaporator C11 The boiling point is relatively low. And by making the heating water FC1 flow through the evaporator heat exchanger C12, the feed water FC3 stored in the evaporator C11 is heated and boiled, and the water vapor S generated by the boiling passes through the gas passage A5 to the reactor A1. Will be supplied. Further, if the evaporator suction pump C14 is operated to open the evaporator C11 in advance before the gas shutoff valve C6 is opened, the evaporator C11 and the reaction can be performed even after the gas shutoff valve C6 is opened. Since the internal pressure of the vessel A1 can be kept lower, boiling of the feed water FC3 in the evaporator C11 can be promoted, and more steam S can be supplied to the reactor A1 on the heat transfer unit A side.

〔放熱操作〕
このような熱需要部Ｃにおいては、熱回収手段Ｃ２を作動させて熱搬送ユニットＡ側の反応材Ａ２から熱を回収しながら、水蒸気供給手段Ｃ１を作動させて熱搬送ユニットＡ側の反応器Ａ１へ水蒸気Ｓを供給して、反応材Ａ２に水和反応をさせる形態で、熱搬送ユニットＡ側の熱を熱需要部Ｃに放熱する放熱操作を実行することができ、その詳細について以下に説明する。 [Heat dissipation operation]
In such a heat demand section C, the heat recovery means C2 is operated to recover heat from the reaction material A2 on the heat transfer unit A side, while the water vapor supply means C1 is operated to operate the reactor on the heat transfer unit A side. In the form of supplying water vapor S to A1 and causing the reaction material A2 to undergo a hydration reaction, a heat dissipating operation for dissipating the heat on the heat transfer unit A side to the heat demanding part C can be executed. explain.

熱需要部Ｃにおいて放熱操作を実行するにあたり、先ず、反応材Ａ２が前述した蓄熱操作における脱水反応後の脱水状態である熱搬送ユニットＡを搭載したトレーラＴを準備し、熱搬送ユニットＡ側の熱媒接続部Ａ９と熱需要部Ｃ側の熱媒接続部Ｃ９とを接続して夫々の熱媒遮断弁Ａ８，Ｃ８を開放し、更に、熱搬送ユニットＡ側のガス接続部Ａ７と熱需要部Ｃ側のガス接続部Ｃ７とを接続して夫々のガス遮断弁Ａ６，Ｃ６を開放する。   In performing the heat radiation operation in the heat demanding part C, first, the trailer T on which the reaction material A2 is mounted with the heat transfer unit A in the dehydration state after the dehydration reaction in the heat storage operation described above is prepared, and the heat transfer unit A side The heat medium connection part A9 and the heat medium connection part C9 on the heat demand part C side are connected to open the respective heat medium shutoff valves A8, C8, and further, the gas connection part A7 on the heat transfer unit A side and the heat demand The gas shutoff valves A6 and C6 are opened by connecting the gas connecting part C7 on the part C side.

次に、上記蒸発器用吸引ポンプＣ１４による蒸発器Ｃ１１からのガスの吸引を行って、蒸発器Ｃ１１の内圧を例えば５ｋＰａに低下させる。
そして、蒸発器用吸引ポンプＣ１４の作動を停止して、上記循環ポンプＣ２２による熱搬送ユニットＡ側の反応器用熱交換器Ａ３への熱媒流体ＦＡ１の循環を開始すると共に、熱回収用熱交換器Ｃ２１への比較的低温の循環水ＦＣ２の供給を開始して熱媒流体ＦＡ１の加熱を開始する。 Next, gas is sucked from the evaporator C11 by the evaporator suction pump C14, and the internal pressure of the evaporator C11 is reduced to, for example, 5 kPa.
Then, the operation of the evaporator suction pump C14 is stopped, and the circulation of the heat transfer fluid FA1 to the reactor heat exchanger A3 on the heat transfer unit A side by the circulation pump C22 is started, and the heat recovery heat exchanger Supply of relatively low-temperature circulating water FC2 to C21 is started, and heating of the heat medium fluid FA1 is started.

そして、上記のような放熱操作を実行することで、熱搬送ユニットＡ側の反応器Ａ１においては、熱需要部Ｃ側の蒸発器Ｃ１１にて給水ＦＣ３が沸騰して生成された水蒸気Ｓが供給されながら、反応材Ａ２が反応器用熱交換器Ａ３における熱媒流体ＦＡ１との熱交換により冷却されることになる。
すると、反応材Ａ２は、以下の化学反応式（２）で示されるように、下記Δｈに相当する発熱を伴う水和反応を行う形態で、蓄えていた熱を熱需要部Ｃ側へ放出することになり、この水和反応に必要な水蒸気Ｓが、熱需要部Ｃ側の蒸発器Ｃ１１から供給されることになる。 Then, by performing the heat radiation operation as described above, in the reactor A1 on the heat transfer unit A side, the water vapor S generated by boiling the feed water FC3 in the evaporator C11 on the heat demand section C side is supplied. However, the reaction material A2 is cooled by heat exchange with the heat medium fluid FA1 in the reactor heat exchanger A3.
Then, as shown in the following chemical reaction formula (2), the reaction material A2 releases the stored heat to the heat demand part C side in a form in which a hydration reaction accompanied by heat generation corresponding to the following Δh is performed. That is, the water vapor S necessary for this hydration reaction is supplied from the evaporator C11 on the heat demand section C side.

ＣａＣｌ2・Ｈ2Ｏ＋３Ｈ2Ｏ（ｇａｓ）−Δｈ→ＣａＣｌ2・４Ｈ2Ｏ・・・（２） CaCl 2 · H 2 O + 3H 2 O (gas) −Δh → CaCl 2 · 4H 2 O (2)

上記のような放熱操作を実行した後には、夫々の熱媒遮断弁Ａ８，Ｃ８を遮断して熱搬送ユニットＡ側の熱媒接続部Ａ９と熱需要部Ｃ側の熱媒接続部Ｃ９との接続を解除し、更に、夫々のガス遮断弁Ａ６，Ｃ６を遮断して熱搬送ユニットＡ側のガス接続部Ａ７と熱需要部Ｃ側のガス接続部Ｃ７との接続を解除する。そして、このように反応材Ａ２が水和反応後の水和状態となった熱搬送ユニットＡは、トレーラＴに搭載されて、前述した熱需要部Ｃに搬送されることになる。   After performing the heat radiation operation as described above, the respective heat medium shutoff valves A8 and C8 are shut off, and the heat medium connection part A9 on the heat transfer unit A side and the heat medium connection part C9 on the heat demand part C side are connected. The connection is released, and the gas shutoff valves A6 and C6 are shut off to release the connection between the gas connection part A7 on the heat transfer unit A side and the gas connection part C7 on the heat demand part C side. Then, the heat transfer unit A in which the reaction material A2 is in a hydrated state after the hydration reaction is mounted on the trailer T and transferred to the heat demand unit C described above.

［別実施形態］
本発明のその他の実施形態について説明する。尚、以下に説明する各実施形態の構成は、それぞれ単独で適用されるものに限られず、矛盾が生じない限り、他の実施形態の構成と組み合わせて適用することも可能である。 [Another embodiment]
Other embodiments of the present invention will be described. Note that the configuration of each embodiment described below is not limited to being applied independently, and can be applied in combination with the configuration of other embodiments as long as no contradiction arises.

（１）上記実施形態では、熱発生部Ｂにおけるガス吸引手段Ｂ１を、ガス吸引ポンプＢ１１で構成したが、図４に示すように改変することができる。
即ち、図４に示すガス吸引手段Ｂ１は、反応器Ａ１に連通するガス通路Ａ５にガス接続部Ｂ７及びガス遮断弁Ｂ６を介して接続可能に配置された凝縮器Ｂ１２と、凝縮器Ｂ１２の内部を冷却水ＦＢ２との熱交換により冷却する凝縮器用熱交換器Ｂ１３（凝縮器用熱交換部の一例）と、当該凝縮器Ｂ１２を減圧可能な凝縮器用吸引ポンプＢ１５とを備えて構成されている。
上記凝縮器Ｂ１２は、内部に水を貯留することができる密閉容器で構成されており、その天井部はガス遮断弁Ｂ６を介してガス接続部Ｂ７に連通されている。
上記凝縮器用熱交換器Ｂ１３は、凝縮器Ｂ１２の内部に配置した伝熱管内に冷却水ＦＢ２を通流させる形態で当該凝縮器Ｂ１２の内部の水蒸気Ｓなどのガスと冷却水ＦＢ２との間で熱交換を行うものとして構成されている。
上記凝縮器用吸引ポンプＢ１５は、その一次側が凝縮器Ｂ１２の天井部に接続されており、凝縮器Ｂ１２の内部からガスを吸引して外部に排出することで、凝縮器Ｂ１２の内圧を低下させるように構成されている。
また、凝縮器Ｂ１２の底部には、排水弁Ｂ１４が接続されており、この排水弁Ｂ１４を開放することで、凝縮器Ｂ１２の内部に貯留する凝縮水を外部に排出することができる。
このように構成されたガス吸引手段Ｂ１を蓄熱操作において作動させることにより、熱搬送ユニットＡ側の反応器Ａ１からガスとしての水蒸気Ｓを吸引することができるのであるが、その作動手順の詳細について、以下に説明を加える。
先ず、排水弁Ｂ１４を開放して凝縮器Ｂ１２に溜まっている水を排出した後に当該排水弁Ｂ１４を遮断した状態で、凝縮器用吸引ポンプＢ１５を作動させて、凝縮器Ｂ１２の内圧を低下させる。次に、前述した与熱手段Ｂ２を作動させて反応材Ａ２を当該反応器用熱交換器Ａ３による熱交換により加熱しながら、ガス遮断弁Ｂ６を開放して、減圧された凝縮器Ｂ１２を反応器Ａ１に接続した状態で、凝縮器用熱交換器Ｂ１３に比較的低温の冷却水ＦＢ２を通流させる。
すると、凝縮器Ｂ１２において水蒸気Ｓが凝縮器用熱交換器Ｂ１３による熱交換により冷却されて凝縮することに伴って、反応器Ａ１における脱水反応により生成された水蒸気Ｓが当該反応器Ａ１からガス通路Ａ５を通じて凝縮器Ｂ１２へ向けて通流することになり、反応材Ａ２の脱水反応が継続されることになる。 (1) In the above embodiment, the gas suction means B1 in the heat generating part B is configured by the gas suction pump B11, but can be modified as shown in FIG.
That is, the gas suction means B1 shown in FIG. 4 includes a condenser B12 disposed so as to be connectable to a gas passage A5 communicating with the reactor A1 via a gas connection portion B7 and a gas shutoff valve B6, and the interior of the condenser B12. Is provided with a condenser heat exchanger B13 (an example of a condenser heat exchanging unit) that cools the condenser B12 by heat exchange with the cooling water FB2 and a condenser suction pump B15 that can depressurize the condenser B12.
The condenser B12 is formed of a sealed container capable of storing water therein, and the ceiling portion thereof is communicated with a gas connection portion B7 via a gas cutoff valve B6.
The condenser heat exchanger B13 is configured such that the cooling water FB2 flows through the heat transfer pipe disposed inside the condenser B12 and between the cooling water FB2 and the gas such as the water vapor S inside the condenser B12. It is configured to perform heat exchange.
The primary side of the condenser suction pump B15 is connected to the ceiling of the condenser B12, and the internal pressure of the condenser B12 is reduced by sucking gas from the inside of the condenser B12 and discharging it to the outside. It is configured.
In addition, a drain valve B14 is connected to the bottom of the condenser B12. By opening the drain valve B14, the condensed water stored in the condenser B12 can be discharged to the outside.
By operating the gas suction means B1 thus configured in the heat storage operation, the water vapor S as gas can be sucked from the reactor A1 on the heat transfer unit A side. A description will be added below.
First, the drain valve B14 is opened to discharge the water accumulated in the condenser B12, and then the condenser suction pump B15 is operated in a state where the drain valve B14 is shut off, thereby reducing the internal pressure of the condenser B12. Next, while the above-described heating means B2 is operated to heat the reaction material A2 by heat exchange by the reactor heat exchanger A3, the gas shut-off valve B6 is opened, and the decompressed condenser B12 is replaced with the reactor. In a state of being connected to A1, the cooling water FB2 having a relatively low temperature is passed through the condenser heat exchanger B13.
Then, as the steam S is cooled and condensed in the condenser B12 by the heat exchange by the condenser heat exchanger B13, the steam S generated by the dehydration reaction in the reactor A1 flows from the reactor A1 to the gas passage A5. Then, the refrigerant flows toward the condenser B12, and the dehydration reaction of the reactant A2 is continued.

（２）上記実施の形態では、熱需要部Ｃにおいて、蒸発器用熱交換器Ｃ１２に通流させる加熱水ＦＣ１と、熱回収用熱交換器Ｃ２１に通流させる循環水ＦＣ２とを別のものとして説明したが、例えば、蒸発器用熱交換器Ｃ１２を熱媒回収用熱交換器Ｃ２１の下流側とする形態で、それらを直列に接続して、熱媒回収用熱交換器Ｃ２１で加熱された循環水Ｆ２１を蒸発器用熱交換器Ｃ１２に供給して、水の加熱用として利用しても構わない。 (2) In the above embodiment, in the heat demand section C, the heating water FC1 to be passed to the evaporator heat exchanger C12 and the circulating water FC2 to be passed to the heat recovery heat exchanger C21 are different. As described above, for example, in a form in which the evaporator heat exchanger C12 is located downstream of the heat medium recovery heat exchanger C21, they are connected in series and are heated by the heat medium recovery heat exchanger C21. The water F21 may be supplied to the evaporator heat exchanger C12 and used for heating the water.

（３）上記実施の形態では、各種熱交換部を、一方の流体が存在する空間内に設置した伝熱管内に他方の流体を通流させて、それら流体間の熱交換を行うチューブ式の熱交換器として構成したが、例えばプレート式等の別の熱交換器として構成しても構わない。 (3) In the above-described embodiment, various heat exchanging units are tube-type tubes that allow the other fluid to flow through a heat transfer tube installed in a space where one fluid exists and exchange heat between the fluids. Although configured as a heat exchanger, it may be configured as another heat exchanger such as a plate type.
