コンテナ型圧縮空気貯蔵発電装置Container type compressed air storage power generator
　本発明は、圧縮空気貯蔵発電装置に関する。 The present invention relates to a compressed air storage power generator.
　圧縮空気貯蔵（ＣＡＥＳ：Compressed Air Energy Storage）発電装置は、電力プラントのオフピーク時間中に電気エネルギーを圧縮空気として貯蔵し、高電力需要時間中に貯蔵した圧縮空気により発電機を作動させて電気エネルギーを生成する。 Compressed Air Storage (CAES) power generators store electrical energy as compressed air during off-peak hours of the power plant and operate the generator with compressed air stored during high power demand times to generate electrical energy. Is generated.
　通常のＣＡＥＳ発電装置は、圧縮空気の貯蔵中に圧縮熱を放出するため、エネルギー損失が生じる。これを防止してシステム効率を改善したのが断熱圧縮空気貯蔵（ＡＣＡＥＳ：Adiabatic Compressed Air Energy Storage）発電装置である。ＡＣＡＥＳ発電装置は、圧縮熱を回収及び貯蔵し、圧縮空気の貯蔵中の圧縮熱の放出を防止する。そして、貯蔵した熱を、膨張機を駆動する際の圧縮空気に戻すことでシステム効率を改善している。 An ordinary CAES power generator emits compression heat during storage of compressed air, resulting in energy loss. Adiabatic-compressed-air-energy storage (ACAES) power generators have prevented this and improved system efficiency. The ACAES generator collects and stores compression heat and prevents the release of compression heat during storage of compressed air. And the system efficiency is improved by returning the stored heat to the compressed air when the expander is driven.
　このようなＡＣＡＥＳ発電装置が、例えば、特許文献１に開示されている。 Such an ACAES power generator is disclosed in Patent Document 1, for example.
　特許文献１には、圧縮熱を熱エネルギー貯蔵（ＴＥＳ：Thermal Energy Storage）システムに保存する、ＡＣＡＥＳ発電装置が開示されている。 Patent Document 1 discloses an ACAES power generator that stores compression heat in a thermal energy storage (TES) system.
　特許文献１に開示されたものを含む従来のＣＡＥＳ発電装置は、圧縮機、発電機、及びタンクなどを全て現地組み立てするため、運搬が煩雑で施工に時間と費用がかかる。 Conventional CAES power generation devices including those disclosed in Patent Document 1 are all assembled on-site as a compressor, a generator, a tank, and the like. Therefore, transportation is complicated and time and cost are required for construction.

As described above, the number of generators 9a to 9c to be used may be adjusted by the valves 18d to 18f to adjust the amount of power to be generated.
　空気供給管１４のコンテナ４の内外の配管について説明する。空気供給管１４は、コンテナ４外のタンク８と、コンテナ４内の圧縮機５ａ～５ｃ及び発電機９ａ～９ｃを接続している。例えば、一点鎖線４Ａで示すように、空気供給管１４をコンテナ４内で合流させた後、コンテナ４外へ取り出す構成とした場合、コンテナ４外の配管は少なくできるがコンテナ４内の余剰スペースを圧迫する。これに代えて、二点鎖線４Ｂで示すように、空気供給管１４をコンテナ４外へ取り出した後、コンテナ４外で合流させる構成とした場合、コンテナ４外の配管は多いがコンテナ４内に余剰スペースを確保できる。従って、空気供給管１４の配管の処理やコンテナ４内の余剰スペースの必要性を考慮して構成を変更してもよい。 The piping inside and outside the container 4 of the air supply pipe 14 will be described. The air supply pipe 14 connects the tank 8 outside the container 4 to the compressors 5a to 5c and the generators 9a to 9c in the container 4. For example, as shown by the one-dot chain line 4A, when the air supply pipe 14 is merged in the container 4 and then taken out of the container 4, the piping outside the container 4 can be reduced, but the excess space in the container 4 can be reduced. Squeeze. Instead, as shown by a two-dot chain line 4B, when the air supply pipe 14 is taken out of the container 4 and then merged outside the container 4, there are many pipes outside the container 4, but inside the container 4 Extra space can be secured. Therefore, the configuration may be changed in consideration of the processing of the piping of the air supply pipe 14 and the necessity of extra space in the container 4.
　制御装置１２は、制御盤２２、インバータ２４、リアクトル２６、及びコンバータ２８を含む。これらにより、コンテナ型ＣＡＥＳ発電装置２の各部は電気的に接続可能である。ただし、出力の方式によってはコンバータ２８を省略してもよい。制御装置１２はまた、圧縮機５ａ～５ｃ、発電機９ａ～９ｃ、及び弁１８ａ～１８ｆに電気的に接続されており、それぞれの動作を制御している。例えば、制御装置１２は変動電力の平滑化制御を行う。この場合、図示しない電力源からの変動電力が所定の値より大きいときは弁１８ａ～１８ｃを開いて圧縮機５ａ～５ｃを駆動し、タンク８に圧縮空気を貯蔵して蓄電する。また、図示しない電力源からの変動電力が所定の値より小さいときは弁１８ａ～１８ｃを開き、タンク８からの圧縮空気により発電機９ａ～９ｃを駆動して発電する。ここで使用される所定の値は、過去の電力需要データに基づいて必要な電力値を決定してもよい。このようにして、制御装置１２は、圧縮機５ａ～５ｃ、発電機９ａ～９ｃ、及び弁１８ａ～１８ｆを駆動制御し、変動電力を平滑化できる。制御装置１２は変動電力の平滑化制御だけでなく、先に記載のようにピークカットに使用されてもよい。 The control device 12 includes a control panel 22, an inverter 24, a reactor 26, and a converter 28. As a result, each part of the container-type CAES power generator 2 can be electrically connected. However, the converter 28 may be omitted depending on the output method. The control device 12 is also electrically connected to the compressors 5a to 5c, the generators 9a to 9c, and the valves 18a to 18f, and controls their operations. For example, the control device 12 performs smoothing control of the variable power. In this case, when the fluctuating power from a power source (not shown) is larger than a predetermined value, the valves 18a to 18c are opened to drive the compressors 5a to 5c, and the compressed air is stored in the tank 8 and stored. When the fluctuating power from a power source (not shown) is smaller than a predetermined value, the valves 18a to 18c are opened, and the generators 9a to 9c are driven by compressed air from the tank 8 to generate power. The predetermined value used here may determine a necessary power value based on past power demand data. In this way, the control device 12 can drive and control the compressors 5a to 5c, the generators 9a to 9c, and the valves 18a to 18f to smooth the fluctuating power. The control device 12 may be used not only for smoothing control of variable power but also for peak cut as described above.
　本実施形態のコンテナ４は、多種類の一般貨物輸送に使用される長さが４０フィートのコンテナである。ただし、コンテナ４の種類やサイズはこれに限定されず、例えば長さが２０フィートのコンテナなど、他に通常よく使用されるコンテナを使用してもよい。 The container 4 of the present embodiment is a container having a length of 40 feet used for various types of general cargo transportation. However, the type and size of the container 4 are not limited to this, and other commonly used containers such as a container having a length of 20 feet may be used.
　このコンテナ型ＣＡＥＳ発電装置２によれば、ＣＡＥＳ発電設備をコンテナ４内に収納する事で、運搬及び現地施工を容易にできる。さらに、発電時間によって必要容量が変わるタンク８をコンテナ４外に配置する事で、必要発電時間の短長によるＣＡＥＳ発電設備部分の設計変更が不要となり、同じパッケージ（圧縮機５ａ～５ｃ、発電機９ａ～９ｃ、及び制御装置１２）を使用できるため経済的である。また、コンテナ型であるため、複数台並べて使用でき、増設による大容量化が容易である。さらに、屋外への設置も可能である。また、コンテナ４としてサイドオープンコンテナを使用してメンテナンスを容易にしてもよい。 According to this container-type CAES power generation device 2, the CAES power generation equipment is stored in the container 4, so that transportation and on-site construction can be facilitated. Furthermore, by disposing the tank 8 whose required capacity changes depending on the power generation time outside the container 4, it is not necessary to change the design of the CAES power generation equipment due to the short required power generation time, and the same package (compressors 5a to 5c, generator Since 9a to 9c and the control device 12) can be used, it is economical. Moreover, since it is a container type, a plurality of units can be used side by side, and it is easy to increase the capacity by expansion. Furthermore, it can be installed outdoors. Further, a side open container may be used as the container 4 to facilitate maintenance.
　本実施形態では、圧縮機５ａ～５ｃ及び発電機９ａ～９ｃの両方をコンテナ４内に配置しているが、いずれか一方のみをコンテナ４内に配置してもよい。制御装置１２もまた、コンテナ４外に配置してもよい。 In this embodiment, both the compressors 5a to 5c and the generators 9a to 9c are arranged in the container 4, but only one of them may be arranged in the container 4. The control device 12 may also be disposed outside the container 4.

The first heat exchangers 30a to 30c, the second heat exchangers 32a to 32c, and the heat storage tanks 33a and 33b are connected via a heat storage fluid supply pipe 34 (see FIG. 4). In the present embodiment, in the container 4, the first heat exchangers 30a to 30c (compressors 5a to 5c) and the second heat exchangers 32a to 32c (generators 9a to 9c) are sequentially arranged from the left side in FIGS. 3A and 3B. , And the control device 12 are generally arranged in a line.
　蓄熱流体供給管３４の内部には蓄熱流体が流れている。蓄熱流体供給管３４には蓄熱流体を流動させるためのポンプ３６ａ～３６ｆが設けられている。蓄熱流体は、ポンプ３６ａ～３６ｆからの圧力によって、第１熱交換器３０ａ～３０ｃと第２熱交換器３２ａ～３２ｃと蓄熱タンク３３ａ，３３ｂとの間を循環流動する。 The heat storage fluid flows inside the heat storage fluid supply pipe 34. The heat storage fluid supply pipe 34 is provided with pumps 36a to 36f for causing the heat storage fluid to flow. The heat storage fluid circulates and flows between the first heat exchangers 30a to 30c, the second heat exchangers 32a to 32c, and the heat storage tanks 33a and 33b by the pressure from the pumps 36a to 36f.
　第１熱交換器３０ａ～３０ｃは、各圧縮機５ａ～５ｃに対して１つずつ設けられている。第１熱交換器３０ａ～３０ｃは、圧縮機５ａ～５ｃとタンク８の間の空気供給管１４を流れる空気と、蓄熱流体供給管３４を流れる蓄熱流体との間で熱交換する。具体的には、圧縮機５ａ～５ｃにより圧縮され、その際に圧縮熱を付加された空気から熱回収し、この熱で蓄熱流体を加熱する。加熱された蓄熱流体は、蓄熱流体供給管３４を通じて第１蓄熱タンク３３ａに供給される。 The first heat exchangers 30a to 30c are provided one for each of the compressors 5a to 5c. The first heat exchangers 30a to 30c exchange heat between the air flowing through the air supply pipe 14 between the compressors 5a to 5c and the tank 8 and the heat storage fluid flowing through the heat storage fluid supply pipe 34. Specifically, heat is recovered from the air compressed by the compressors 5a to 5c and added with heat of compression at that time, and the heat storage fluid is heated by this heat. The heated heat storage fluid is supplied to the first heat storage tank 33 a through the heat storage fluid supply pipe 34.
　第１蓄熱タンク３３ａは、第１熱交換器３０ａ～３０ｃで加熱され、昇温した蓄熱流体を貯蔵する。第１蓄熱タンク３３ａは、貯蔵している昇温した蓄熱流体の熱を外部に放出しないように、断熱部材から形成されていることが好ましい。第１蓄熱タンク３３ａで貯蔵されている昇温した蓄熱流体は蓄熱流体供給管３４を通じて第２熱交換器３２ａ～３２ｃに供給される。 The first heat storage tank 33a stores the heat storage fluid heated by the first heat exchangers 30a to 30c and heated. It is preferable that the 1st heat storage tank 33a is formed from the heat insulation member so that the heat | fever of the heat storage fluid which temperature-rises stored may not be discharge | released outside. The heated heat storage fluid stored in the first heat storage tank 33a is supplied to the second heat exchangers 32a to 32c through the heat storage fluid supply pipe.
　第２熱交換器３２ａ～３２ｃは、各発電機９ａ～９ｃに対して１つずつ設けられている。第２熱交換器３２ａ～３２ｃは、蓄熱流体供給管３４を流れる昇温した蓄熱流体と、タンク８と発電機９ａ～９ｃの間の空気供給管１４を流れる圧縮空気との間で熱交換する。具体的には、昇温した蓄熱流体から熱回収し、この熱で圧縮空気を加熱する。加熱され、昇温した圧縮空気は、空気供給管１４を通じて発電機９ａ～９ｃに供給される。第２熱交換器３２ａ～３２ｃで熱回収され降温した蓄熱流体は、蓄熱流体供給管３４を通じて第２蓄熱タンク３３ｂに供給される。 One second heat exchanger 32a to 32c is provided for each of the generators 9a to 9c. The second heat exchangers 32a to 32c exchange heat between the heated heat storage fluid flowing through the heat storage fluid supply pipe 34 and the compressed air flowing through the air supply pipe 14 between the tank 8 and the generators 9a to 9c. . Specifically, heat is recovered from the heated heat storage fluid, and the compressed air is heated with this heat. The heated and heated compressed air is supplied to the generators 9a to 9c through the air supply pipe. The heat storage fluid that has been heat-recovered and cooled by the second heat exchangers 32a to 32c is supplied to the second heat storage tank 33b through the heat storage fluid supply pipe.
　第２蓄熱タンク３３ｂは、第２熱交換器３２ａ～３２ｃで熱回収され、降温した蓄熱流体を貯蔵する。第２蓄熱タンク３３ｂは、貯蔵している蓄熱流体の熱を外部に放出しないように、断熱部材から形成されていることが好ましい。第２蓄熱タンク３３ｂで貯蔵されている蓄熱流体は蓄熱流体供給管３４を通じて第１熱交換器３０ａ～３０ｃに供給される。 The second heat storage tank 33b stores the heat storage fluid that has been heat-recovered and lowered in temperature by the second heat exchangers 32a to 32c. The second heat storage tank 33b is preferably formed of a heat insulating member so as not to release the heat of the stored heat storage fluid to the outside. The heat storage fluid stored in the second heat storage tank 33b is supplied to the first heat exchangers 30a to 30c through the heat storage fluid supply pipe.
　このように、蓄熱流体は、第１熱交換器３０ａ～３０ｃで加熱され、第１蓄熱タンク３３ａで貯蔵され、第２熱交換器３２ａ～３２ｃで冷却され、第２蓄熱タンク３３ｂで貯蔵され、第１熱交換器３０ａ～３０ｃへと戻り加熱され、これを繰り返す。 Thus, the heat storage fluid is heated by the first heat exchangers 30a to 30c, stored in the first heat storage tank 33a, cooled by the second heat exchangers 32a to 32c, and stored in the second heat storage tank 33b. It returns to the 1st heat exchangers 30a-30c, is heated, and this is repeated.
　蓄熱流体供給管３４のコンテナ４の内外の配管については空気供給管１４と同様である。蓄熱流体供給管３４は、コンテナ４外の蓄熱タンク３３ａ，３３ｂと、コンテナ４内の第１熱交換器３０ａ～３０ｃ及び第２熱交換器３２ａ～３２ｃを接続している。例えば、一点鎖線４Ａで示すように、蓄熱流体供給管３４をコンテナ４内で合流させた後、コンテナ４外へ取り出す構成とした場合、コンテナ４外の配管は少なくできるがコンテナ４内の余剰スペースを圧迫する。これに代えて、二点鎖線４Ｂで示すように、蓄熱流体供給管３４をコンテナ４外へ取り出した後、コンテナ４外で合流させる構成とした場合、コンテナ４外の配管は多いがコンテナ４内に余剰スペースを確保しやすい。従って、蓄熱流体供給管３４の配管の処理やコンテナ４内の余剰スペースの必要性を考慮して構成を変更してもよい。 The piping inside and outside the container 4 of the heat storage fluid supply pipe 34 is the same as the air supply pipe 14. The heat storage fluid supply pipe 34 connects the heat storage tanks 33 a and 33 b outside the container 4 to the first heat exchangers 30 a to 30 c and the second heat exchangers 32 a to 32 c in the container 4. For example, as shown by the one-dot chain line 4A, when the heat storage fluid supply pipe 34 is joined in the container 4 and then taken out of the container 4, the piping outside the container 4 can be reduced, but the excess space in the container 4 can be reduced. Squeeze. Instead, as shown by a two-dot chain line 4B, when the heat storage fluid supply pipe 34 is taken out of the container 4 and then merged outside the container 4, there are many pipes outside the container 4, but inside the container 4 It is easy to secure extra space. Therefore, the configuration may be changed in consideration of the processing of the piping of the heat storage fluid supply pipe 34 and the necessity of excess space in the container 4.
　本実施形態では、図４のようにポンプ３６ａ～３６ｆがコンテナ４内に設けられている。このようにすることで、運搬及び施工が容易になる。しかし、ポンプ３６ａ～３６ｆは必ずしもコンテナ４内に限らず、図５のようにコンテナ４外に設けられていてもよい。このようにすれば、コンテナ４内に余剰スペースを確保しやすい。また、本実施形態では、蓄熱流体供給管３４が合流して一本になっている位置にポンプを設けるようにすれば、ポンプ台数を減らすことができる。 In this embodiment, pumps 36a to 36f are provided in the container 4 as shown in FIG. By doing in this way, conveyance and construction become easy. However, the pumps 36a to 36f are not necessarily provided inside the container 4, and may be provided outside the container 4 as shown in FIG. In this way, it is easy to secure a surplus space in the container 4. In the present embodiment, the number of pumps can be reduced by providing the pumps at positions where the heat storage fluid supply pipes 34 are joined together.
　本実施形態のコンテナ型ＣＡＥＳ発電装置２によると、発電時間によって必要容量が変わる蓄熱タンク３３ａ，３３ｂをコンテナ４外に配置することで、必要発電時間の短長によるＣＡＥＳ発電設備の設計変更を不要にできる。従って、同じパッケージを使用でき、経済的である。 According to the container type CAES power generation device 2 of the present embodiment, the heat storage tanks 33a and 33b whose required capacity changes depending on the power generation time are arranged outside the container 4, so that the design change of the CAES power generation facility due to the short required power generation time is unnecessary. Can be. Therefore, the same package can be used and it is economical.
　第１熱交換器３０ａ～３０ｃのレイアウトについて説明する。図６Ａ，Ｂは、第１熱交換器３０ａ～３０ｃと圧縮機５ａ～５ｃのレイアウトを示す正面図及び側面図である。本実施形態で使用する圧縮機５ａ～５ｃは、２段型であり、低圧段圧縮部３８と高圧段圧縮部４０を有する。第１熱交換器３０ａ～３０ｃは、圧縮空気に対して、低圧段圧縮部３８による１段階目の圧縮熱を熱回収して冷却するインタークーラ及び高圧段圧縮部４０による２段階目の圧縮熱を熱回収して冷却するアフタークーラとしての役割を果たす。ただし、圧縮機５ａ～５ｃは２段型に限らず、３段型以上であってもよいし、又は単段型であってもよい。 The layout of the first heat exchangers 30a to 30c will be described. 6A and 6B are a front view and a side view showing a layout of the first heat exchangers 30a to 30c and the compressors 5a to 5c. The compressors 5a to 5c used in the present embodiment are of a two-stage type, and have a low-pressure stage compression unit 38 and a high-pressure stage compression unit 40. The first heat exchangers 30a to 30c are an intercooler that recovers and cools the first stage compression heat generated by the low pressure stage compression unit 38 with respect to the compressed air, and a second stage compression heat generated by the high pressure stage compression unit 40. It serves as an aftercooler that recovers and cools the heat. However, the compressors 5a to 5c are not limited to the two-stage type, and may be a three-stage type or a single-stage type.
　第２熱交換器３２ａ～３２ｃのレイアウトについては、第１熱交換器３０ａ～３０ｃと同様である。即ち、図６Ａ，Ｂにおいて、第１熱交換器３０ａ～３０ｃを第２熱交換器３２ａ～３２ｃに置換し、圧縮機５ａ～５ｃを発電機９ａ～９ｃに置換したものと同様である。ただし、第２熱交換器３２ａ～３２ｃは、第１熱交換器３０ａ～３０ｃとは異なり圧縮空気に対してヒータの役割を果たす。即ち、高圧段圧縮部４０による１段階目の膨張前に熱供給するプレヒータ及び低圧段膨張部３８による２段階目の膨張前に熱供給するインターヒータとしての役割を果たす。 The layout of the second heat exchangers 32a to 32c is the same as that of the first heat exchangers 30a to 30c. 6A and 6B, the first heat exchangers 30a to 30c are replaced with the second heat exchangers 32a to 32c, and the compressors 5a to 5c are replaced with the generators 9a to 9c. However, unlike the first heat exchangers 30a to 30c, the second heat exchangers 32a to 32c serve as a heater for the compressed air. That is, it functions as a preheater that supplies heat before the first stage expansion by the high-pressure stage compression unit 40 and an interheater that supplies heat before the second stage expansion by the low-pressure stage expansion unit 38.
　第１熱交換器３０ａ～３０ｃ（第２熱交換器３２ａ～３２ｃ）は、図６Ａ，Ｂに示すように、圧縮機５ａ～５ｃ（発電機９ａ～９ｃ）と重なるようにその下方側に配置されている。従って、このように重ねて配置することで、コンテナ４内の設置面積を大きく占有せずに空間を有効利用できる。また、圧縮機５ａ～５ｃと第１熱交換器３０ａ～３０ｃ又は発電機９ａ～９ｃと第２熱交換器３２ａ～３２ｃを重ねて近接配置していることでこれらを接続する空気供給管１４の長さを短縮できるため、内部を流れる圧縮空気の圧力損失及び熱損失を低減できる。 As shown in FIGS. 6A and 6B, the first heat exchangers 30a to 30c (second heat exchangers 32a to 32c) are arranged below the compressors 5a to 5c (generators 9a to 9c). Has been. Therefore, by arranging in such a manner, the space can be effectively used without occupying a large installation area in the container 4. Further, the compressors 5a to 5c and the first heat exchangers 30a to 30c or the generators 9a to 9c and the second heat exchangers 32a to 32c are arranged in close proximity to each other, so that the air supply pipe 14 that connects them is provided. Since the length can be shortened, the pressure loss and heat loss of the compressed air flowing inside can be reduced.
　ＣＡＥＳ発電設備をコンテナ４内に収容する場合、圧縮機５ａ～５ｃ（又は発電機９ａ～９ｃ）などが発熱するため、コンテナ４内の温度が上昇し、制御装置１２などの電子機器が高熱に晒されるおそれがある。しかし、ＡＣＡＥＳ発電設備を使用して熱回収を行う場合、コンテナ４内の温度上昇を抑制できるため、制御装置１２などの電子機器を熱によるダメージから守ることができる。さらに言えば、特願２０１４－１７２８３６号で本願出願人が提案している発生する熱を全て回収する全熱回収型のＡＣＡＥＳ発電設備を使用すれば、コンテナ４内における放熱が殆ど存在しないため、換気扇や空調設備が不要である。従って、空気の出入りが可能な通気口を設けるだけでよい。 When the CAES power generation facility is accommodated in the container 4, the compressors 5 a to 5 c (or the generators 9 a to 9 c) generate heat, so that the temperature in the container 4 rises and the electronic equipment such as the control device 12 becomes hot. There is a risk of exposure. However, when heat recovery is performed using the ACAES power generation facility, an increase in temperature in the container 4 can be suppressed, so that electronic devices such as the control device 12 can be protected from damage due to heat. Furthermore, if a total heat recovery type ACAES power generation facility that recovers all generated heat proposed by the applicant of this application in Japanese Patent Application No. 2014-172836 is used, there is almost no heat dissipation in the container 4, Ventilation fans and air conditioning equipment are not required. Therefore, it is only necessary to provide a vent hole through which air can enter and exit.

The container-type CAES power generation apparatus 2 of the present embodiment is the same as the second embodiment of FIGS. 3A to 3C and FIG. 4 except for the portion related to the container 4 (the first container 4a and the second container 4b). Therefore, the same components as those shown in FIGS. 3A to 3C and FIG.
　図７Ａ～Ｃ及び図８を参照して、本実施形態のコンテナ型ＣＡＥＳ発電装置２は、第１コンテナ４ａ及び第２コンテナ４ｂを備える。第１コンテナ４ａ及び第２コンテナ４ｂは、多種類の一般貨物輸送に使用される長さが２０フィートのコンテナである。第１コンテナ４ａ及び第２コンテナ４ｂのサイズに関しては、これに限定されず、例えば長さが４０フィートのコンテナなど、他に通常よく使用されるコンテナを使用してもよい。 7A to 7C and FIG. 8, the container-type CAES power generator 2 of the present embodiment includes a first container 4a and a second container 4b. The first container 4a and the second container 4b are containers having a length of 20 feet used for various types of general cargo transportation. The size of the first container 4a and the second container 4b is not limited to this, and other commonly used containers such as a container having a length of 40 feet may be used.
　第１コンテナ４ａ内には、圧縮機能に関する設備が収納されている。圧縮機能に関する設備には、圧縮機５ａ～５ｃ、第１熱交換器３０ａ～３０ｃ、及びこれらを制御する制御装置１２ａが含まれている。 In the first container 4a, equipment relating to the compression function is stored.

　第２コンテナ４ｂ内には、発電機能に関する設備が収納されている。発電機能に関する設備には、発電機９ａ～９ｃ、第２熱交換器３２ａ～３２ｃ、及びこれらを制御する制御装置１２ｂが含まれている。 The facility relating to the power generation function is stored in the second container 4b. Equipment related to the power generation function includes generators 9a to 9c, second heat exchangers 32a to 32c, and a control device 12b for controlling them.
　空気供給管１４及び蓄熱流体供給管３４の第１コンテナ４ａ及び第２コンテナ４ｂの内外の配管については、第２実施形態と同様である。即ち、空気供給管１４は、第１コンテナ４ａ及び第２コンテナ４ｂ内で合流してもよいし（図８の一点鎖線４Ａ参照）、第１コンテナ４ａ及び第２コンテナ４ｂ外で合流してもよい（図８の二点鎖線４Ｂ参照）。蓄熱流体供給管３４もまた同様である。ポンプ３６ａ～３６ｆについても、図８では第１コンテナ４ａ及び第２コンテナ４ｂ内に配置されているが、第１コンテナ４ａ及び第２コンテナ４ｂ外に配置されてもよいことは第２実施形態と同様である（図４及び図５参照）。 The piping inside and outside the first container 4a and the second container 4b of the air supply pipe 14 and the heat storage fluid supply pipe 34 is the same as in the second embodiment. That is, the air supply pipe 14 may merge within the first container 4a and the second container 4b (see the dashed line 4A in FIG. 8), or may merge outside the first container 4a and the second container 4b. Good (see two-dot chain line 4B in FIG. 8). The same applies to the heat storage fluid supply pipe 34. The pumps 36a to 36f are also arranged in the first container 4a and the second container 4b in FIG. 8, but may be arranged outside the first container 4a and the second container 4b as in the second embodiment. The same applies (see FIGS. 4 and 5).
　このコンテナ型ＣＡＥＳ発電装置２によれば、圧縮機能を有する第１コンテナ４ａと発電機能を有する第２コンテナ４ｂを備えることで、各コンテナ４ａ，４ｂを小型化できる。この小型化により搬送がさらに容易になるとともに、各コンテナ４ａ，４ｂを設置するレイアウトの自由度を拡張できる。 According to this container-type CAES power generator 2, each container 4a, 4b can be reduced in size by including the first container 4a having a compression function and the second container 4b having a power generation function. This downsizing further facilitates the conveyance and expands the degree of freedom of layout for installing the containers 4a and 4b.

The container-type CAES power generator 2 of this embodiment is the same as that of 2nd Embodiment of FIG. 5 except the part regarding the container 41 for thermal storage. Accordingly, parts similar to those in the configuration shown in FIG.
　図９を参照して、本実施形態のコンテナ型ＣＡＥＳ発電装置２は、蓄熱用コンテナ４１を備える。蓄熱用コンテナ４１は、第１蓄熱タンク３３ａ及び第２蓄熱タンク３３ｂを収納している。本実施形態においても、図５のコンテナ４Ａ，４Ｂのように、蓄熱流体供給管３４の配管に応じてそのサイズ及び構成を変更してもよい。例えば、二点鎖線４１Ｂで示すように、蓄熱流体供給管３４を蓄熱用コンテナ４１内で合流させた後、蓄熱用コンテナ４１外へ取り出してもよい。また、一点鎖線４１Ａで示すように、蓄熱流体供給管３４を蓄熱コンテナ４１外へ取り出した後、蓄熱用コンテナ４１外で合流させてもよい。従って、蓄熱流体供給管３４の配管の処理や蓄熱用コンテナ４１内の余剰スペースの必要性を考慮してサイズ及び構成を変更してもよい。 Referring to FIG. 9, the container type CAES power generator 2 of the present embodiment includes a heat storage container 41. The heat storage container 41 houses a first heat storage tank 33a and a second heat storage tank 33b. Also in the present embodiment, the size and configuration may be changed according to the piping of the heat storage fluid supply pipe 34 as in the containers 4A and 4B in FIG. For example, as indicated by a two-dot chain line 41B, the heat storage fluid supply pipe 34 may be merged in the heat storage container 41 and then taken out of the heat storage container 41. Further, as indicated by a one-dot chain line 41 </ b> A, the heat storage fluid supply pipe 34 may be taken out of the heat storage container 41 and then merged outside the heat storage container 41. Therefore, the size and configuration may be changed in consideration of the processing of the piping of the heat storage fluid supply pipe 34 and the need for the extra space in the heat storage container 41.
　蓄熱用コンテナ４１は、内側に断熱材を設けた断熱コンテナ（サーマルコンテナともいう。）であり、第１蓄熱タンク３３ａ及び第２蓄熱タンク３３ｂを分けて収納するよう内部に仕切り４２を備える。第１蓄熱タンク３３ａ及び第２蓄熱タンク３３ｂは、内部に貯蔵する蓄熱流体の温度がそれぞれ異なっているため、仕切り４２を設けることで空間を分けることができ、放熱による熱損失を防止できる。仕切り４２も断熱材により構成することでさらに熱損失を防止できる。 The heat storage container 41 is a heat insulating container (also referred to as a thermal container) provided with a heat insulating material on the inside, and includes a partition 42 inside so as to store the first heat storage tank 33a and the second heat storage tank 33b separately. Since the first heat storage tank 33a and the second heat storage tank 33b have different temperatures of the heat storage fluid stored inside, the space can be divided by providing the partition 42, and heat loss due to heat radiation can be prevented. By configuring the partition 42 with a heat insulating material, heat loss can be further prevented.
　また、本実施形態では、ポンプ３６ａ～３６ｆが蓄熱用コンテナ４１内に設けられている。このようにすることで、運搬及び施工が容易になる。しかし、ポンプ３６ａ～３６ｆは必ずしも蓄熱用コンテナ４１内に限らず、図４のようにコンテナ４内に設けられていてもよいし、コンテナ４，４１の外部に配置されてもよい。好ましくは、より施行を容易にするためにいずれかのコンテナ４，４１内に配置するのがよい。 In this embodiment, the pumps 36 a to 36 f are provided in the heat storage container 41. By doing in this way, conveyance and construction become easy. However, the pumps 36a to 36f are not necessarily provided in the heat storage container 41, and may be provided in the container 4 as shown in FIG. Preferably, it is preferable to arrange in one of the containers 4 and 41 for easier enforcement.
（第５実施形態）
　図１０は、本発明の第５実施形態に係るコンテナ型ＣＡＥＳ発電装置２を示す。本実施形態のコンテナ型ＣＡＥＳ発電装置２は、蓄熱用コンテナ４１（第３コンテナ４１ａ及び第４コンテナ４１ｂ）に関する部分以外の構成は図９の第４実施形態と同様である。従って、図９に示した構成と同様の部分については同様の符号を付して説明を省略する。 (Fifth embodiment)
FIG. 10 shows a container-type CAES power generator 2 according to a fifth embodiment of the present invention. The container-type CAES power generation device 2 of the present embodiment is the same as the fourth embodiment of FIG. 9 except for the portion related to the heat storage container 41 (the third container 41a and the fourth container 41b). Therefore, the same parts as those shown in FIG.
　図１０を参照して、本実施形態のコンテナ型ＣＡＥＳ発電装置２は、蓄熱用コンテナ４１を備える。蓄熱用コンテナ４１は、第３コンテナ４１ａ及び第４コンテナ４１ｂを備える。第３コンテナ４１ａは、第１蓄熱タンク３３ａを収納している。第４コンテナ４１ｂは、第２蓄熱タンク３３ｂを収納している。蓄熱流体供給管３４の第３コンテナ４１ａ及び第４コンテナ４１ｂの内外の配管については、第４実施形態と同様である。即ち、蓄熱流体供給管３４は、第３コンテナ４１ａ及び第４コンテナ４１ｂ内で合流してもよいし（図１０の二点鎖線４１Ｂ参照）、第３コンテナ４１ａ及び第４コンテナ４１ｂ外で合流してもよい（図１０の一点鎖線４１Ａ参照）。ポンプ３６ａ～３６ｆについても、図１０では蓄熱用コンテナ４１内に配置されているが、蓄熱用コンテナ４１外に配置されてもよいことは第２実施形態と同様である。 Referring to FIG. 10, the container type CAES power generator 2 of the present embodiment includes a heat storage container 41. The heat storage container 41 includes a third container 41a and a fourth container 41b. The third container 41a houses the first heat storage tank 33a. The fourth container 41b houses the second heat storage tank 33b. The piping inside and outside the third container 41a and the fourth container 41b of the heat storage fluid supply pipe 34 is the same as in the fourth embodiment. That is, the heat storage fluid supply pipe 34 may merge within the third container 41a and the fourth container 41b (see the two-dot chain line 41B in FIG. 10), or merge outside the third container 41a and the fourth container 41b. (See the alternate long and short dash line 41A in FIG. 10). The pumps 36a to 36f are also arranged in the heat storage container 41 in FIG. 10, but may be arranged outside the heat storage container 41 as in the second embodiment.
　第３コンテナ４１ａ及び第４コンテナ４１ｂは、内側に断熱材を設けた断熱コンテナである。第１蓄熱タンク３３ａ及び第２蓄熱タンク３３ｂは、内部に貯蔵する蓄熱流体の温度がそれぞれ異なっているため、第３コンテナ４１ａ及び第４コンテナ４１ｂのように空間を分けることで、放熱による熱損失を防止できる。また、第１蓄熱タンク３３ａを収納する第３コンテナ４１ａと第２蓄熱タンク３３ｂを収納する第４コンテナ４１ｂを備えることで、各コンテナ４１ａ，４１ｂを小型化できる。この小型化により搬送がさらに容易になるとともに、各コンテナ４１ａ，４１ｂを設置するレイアウトの自由度を拡張できる。 The 3rd container 41a and the 4th container 41b are heat insulation containers which provided the heat insulating material inside. Since the first heat storage tank 33a and the second heat storage tank 33b are different in temperature of the heat storage fluid stored therein, dividing the space like the third container 41a and the fourth container 41b, heat loss due to heat radiation Can be prevented. Moreover, each container 41a, 41b can be reduced in size by providing the 3rd container 41a which accommodates the 1st heat storage tank 33a, and the 4th container 41b which accommodates the 2nd heat storage tank 33b. This downsizing further facilitates the conveyance and expands the degree of freedom of layout for installing the containers 41a and 41b.
　ここで記載した各実施形態では、圧縮機５ａ～５ｃと発電機９ａ～９ｃの台数が等しいものを説明した。しかし、圧縮機５ａ～５ｃと発電機９ａ～９ｃの台数・容量は揃える必要はなく、圧縮機５ａ～５ｃ側を小さく（又は少なく）して発電機９ａ～９ｃ側を大きく（又は多く）することも可能であるし、その反対も可能である。特に第３実施形態では、圧縮機能を有する第１コンテナ４ａの数と発電機能を有する第２コンテナ４ｂの数を変えて使用してもよい。 In the embodiments described here, the compressors 5a to 5c and the generators 9a to 9c are equal in number. However, the number and capacity of the compressors 5a to 5c and the generators 9a to 9c do not need to be equalized, and the compressors 5a to 5c are made smaller (or less) and the generators 9a to 9c are made larger (or more). It is possible, and vice versa. In particular, in the third embodiment, the number of first containers 4a having a compression function and the number of second containers 4b having a power generation function may be changed.
　また、本実施形態では、タンク８をコンテナ外部に隣接して設置したものを例示した。しかし、タンクはこの態様に限定されず、地下に埋設したものであってもよく、また、坑道、地下空洞をタンクとして利用してもよい。 In this embodiment, the tank 8 is installed adjacent to the outside of the container. However, the tank is not limited to this mode, and may be buried underground, or a mine shaft or underground cavity may be used as the tank.
