And the amount of cooling fluid required can be reduced.

本発明は、熱交換流体を所定温度まで加熱又は冷却するヒートポンプを設けたものであるが、ヒートポンプとしては、圧縮機と凝縮器と膨張弁と蒸発器とそれらを接続する管路とで構成される従来周知のものを用いることができる。   The present invention is provided with a heat pump for heating or cooling the heat exchange fluid to a predetermined temperature. The heat pump is composed of a compressor, a condenser, an expansion valve, an evaporator, and a pipe line connecting them. Conventionally known ones can be used.

本実施例においては、熱交換室として反応釜１のジャケット部２を用いた例を示す。反応釜１の内部に入れた図示しない被熱交換物を、ジャケット部２に供給する加熱源としての加熱用蒸気、あるいは、冷却源としての冷却流体、例えば冷却水によって熱交換するものである。   In the present embodiment, an example in which the jacket portion 2 of the reaction kettle 1 is used as a heat exchange chamber is shown. A heat exchange material (not shown) placed in the reaction kettle 1 is heat-exchanged by heating steam as a heating source supplied to the jacket portion 2 or a cooling fluid as a cooling source, for example, cooling water.

反応釜１のほぼ全周にわたりジャケット部２を形成して、このジャケット部２に吸引手段としての組み合わせ真空ポンプ４と、加熱流体としての蒸気供給管８、及び、冷却流体供給管５を接続する。   A jacket portion 2 is formed over almost the entire circumference of the reaction kettle 1, and a combined vacuum pump 4 as a suction means, a steam supply pipe 8 as a heating fluid, and a cooling fluid supply pipe 5 are connected to the jacket portion 2. .

冷却流体供給管５の下方部は、組み合わせ真空ポンプ４の循環路１５の一部と接続すると共に、上方部をジャケット部２と接続する。   The lower part of the cooling fluid supply pipe 5 is connected to a part of the circulation path 15 of the combination vacuum pump 4 and the upper part is connected to the jacket part 2.

ジャケット部２の右側上部には、流量調節弁７を介在した蒸気供給管８を接続する。この蒸気供給管８から、所定圧力すなわち温度の加熱用蒸気が、ジャケット部２へ供給されることによって、反応釜１内の被加熱物を加熱することができるものである。   A steam supply pipe 8 with a flow rate adjusting valve 7 interposed is connected to the upper right portion of the jacket part 2. By supplying steam for heating at a predetermined pressure, that is, temperature from the steam supply pipe 8 to the jacket portion 2, the object to be heated in the reaction kettle 1 can be heated.

蒸気供給管８と並行してバイパス管路１１を設けて、スチームエゼクタ１２を取り付ける。スチームエゼクタ１２の吸引口に後述するフラッシュ蒸気管９の一端を接続する。   A bypass pipe 11 is provided in parallel with the steam supply pipe 8 and a steam ejector 12 is attached. One end of a flash steam pipe 9 to be described later is connected to the suction port of the steam ejector 12.

ジャケット部２の下方に排出管２０，２１を接続して、組み合わせ真空ポンプ４のエゼクタ１０と接続する。排出管２０には蒸気トラップ２２を取り付け、また、排出管２１には制御弁２３を取り付ける。   The discharge pipes 20 and 21 are connected below the jacket portion 2 and connected to the ejector 10 of the combination vacuum pump 4. A steam trap 22 is attached to the discharge pipe 20, and a control valve 23 is attached to the discharge pipe 21.

組み合わせ真空ポンプ４を、エゼクタ１０と、循環ポンプ１４と冷水タンク１３とヒートポンプ３を順次に循環路１５で連通して形成すると共に、循環ポンプ２４と温水タンク２５とヒートポンプ３を循環路２６で連通して形成する。冷水タンク１３の底部には、ヒートポンプ３の冷却部２７を配置する。また、温水タンク２５の底部にはヒートポンプ３の加熱部２８を配置する。   The combination vacuum pump 4 is formed by sequentially connecting the ejector 10, the circulation pump 14, the cold water tank 13, and the heat pump 3 through the circulation path 15, and the circulation pump 24, the hot water tank 25, and the heat pump 3 are communicated through the circulation path 26. To form. A cooling unit 27 of the heat pump 3 is disposed at the bottom of the cold water tank 13. A heating unit 28 of the heat pump 3 is disposed at the bottom of the hot water tank 25.

循環路１５と２６の接続部には三方切換弁２９を接続する。三方切換弁２９の上部弁をエゼクタ１０と接続する。温水タンク２５の上部には、フラッシュ蒸気管９を接続すると共に、余ったフラッシュ蒸気を排出するフラッシュ蒸気排出管３０を接続する。なお、フラッシュ蒸気管９には、温水タンク２５からスチームエゼクタ１２へのフラッシュ蒸気の通過だけを許容する逆止弁６を取り付ける。 A three-way switching valve 29 is connected to the connection between the circulation paths 15 and 26. The upper valve of the three-way switching valve 29 is connected to the ejector 10. A flash steam pipe 9 is connected to the upper part of the hot water tank 25, and a flash steam discharge pipe 30 for discharging excess flash steam is connected. A check valve 6 that allows only flash steam to pass from the hot water tank 25 to the steam ejector 12 is attached to the flash steam pipe 9.

エゼクタ１０と冷水タンク１３の上部を管路３１で接続すると共に、エゼクタ１０と温水タンク２５の上部を管路３２で接続する。 The upper part of the ejector 10 and the cold water tank 13 is connected by a pipe line 31, and the upper part of the ejector 10 and the hot water tank 25 is connected by a pipe line 32.

反応釜１内の被冷却物を冷却する場合は、三方切換弁２９を切り換えて、循環路１５とエゼクタ１０だけが連通して、循環路２６とエゼクタ１０は遮断しておく。循環ポンプ１４を駆動して冷水タンク１３内の冷却水を、エゼクタ１０と冷却流体供給管５からジャケット部２へ供給する。なお、一部の冷水は管路３１を通って冷水タンク１３へと循環する。   When the object to be cooled in the reaction kettle 1 is cooled, the three-way switching valve 29 is switched so that only the circulation path 15 and the ejector 10 communicate with each other, and the circulation path 26 and the ejector 10 are shut off. The circulation pump 14 is driven to supply the cooling water in the cold water tank 13 from the ejector 10 and the cooling fluid supply pipe 5 to the jacket portion 2. A part of the cold water circulates through the pipe line 31 to the cold water tank 13.

冷水タンク１３内の冷水は、ヒートポンプ３の冷却部２７によって所定の温度まで冷却されており、この冷水がエゼクタ１０を通過することにより、エゼクタ１０で所定の吸引力を発生して、排出管２０または２１を介してジャケット部２内を所定の圧力状態、例えば、大気圧以下の真空状態、とすることにより、ジャケット部２内へ噴射される冷却水が反応釜１内の被冷却物の熱を奪って蒸発気化することにより、その蒸発潜熱によって被冷却物を気化冷却することができる。 The cold water in the cold water tank 13 is cooled to a predetermined temperature by the cooling unit 27 of the heat pump 3, and when the cold water passes through the ejector 10, a predetermined suction force is generated in the ejector 10, and the discharge pipe 20 Alternatively, the inside of the jacket portion 2 is brought into a predetermined pressure state, for example, a vacuum state of atmospheric pressure or less, through 21, so that the cooling water injected into the jacket portion 2 is heated by the object to be cooled in the reaction kettle 1. By evaporating and evaporating, the object to be cooled can be vaporized and cooled by the latent heat of vaporization.

ジャケット部２で被冷却物を冷却した冷却流体の気化蒸気及び気化しきれなかった冷却水の一部は、排出管２０または２１を通ってエゼクタ１０に吸引され冷水タンク１３に至る。   The vaporized vapor of the cooling fluid that has cooled the object to be cooled by the jacket portion 2 and a part of the cooling water that could not be vaporized are sucked into the ejector 10 through the discharge pipe 20 or 21 and reach the cold water tank 13.

エゼクタ１０で発生することのできる吸引力は、エゼクタ１０を流下する流体の温度によって決まるために、ヒートポンプ３の冷却部２７の温度を適宜調節することによって、エゼクタ１０を流下する冷却水温度を調節して、エゼクタ１０の吸引力をコントロールすることができる。   Since the suction force that can be generated in the ejector 10 is determined by the temperature of the fluid flowing down the ejector 10, the temperature of the cooling water flowing down the ejector 10 is adjusted by appropriately adjusting the temperature of the cooling unit 27 of the heat pump 3. Thus, the suction force of the ejector 10 can be controlled.

一方、反応釜1内の被加熱物を加熱する場合は、蒸気供給管８から加熱に適した温度の蒸気をジャケット部２へ供給することによって、蒸気が反応釜1内の被加熱物に熱を与えて加熱する。この場合、組み合わせ真空ポンプ４の三方切換弁２９を切り換えて、循環路２６とエゼクタ１０だけを連通し、循環路１５とエゼクタ１０間は遮断すると共に、エゼクタ１０と冷却流体供給管５の間のバルブ３３も閉弁しておく。従って、循環ポンプ２４を駆動することにより、温水タンク２５内の温水は、三方切換弁２９とエゼクタ１０と管路３２を通って循環する。   On the other hand, when the object to be heated in the reaction kettle 1 is heated, the steam is heated to the object to be heated in the reaction kettle 1 by supplying steam at a temperature suitable for heating from the steam supply pipe 8 to the jacket portion 2. Give and heat. In this case, the three-way switching valve 29 of the combination vacuum pump 4 is switched so that only the circulation path 26 and the ejector 10 communicate with each other, the circulation path 15 and the ejector 10 are blocked, and between the ejector 10 and the cooling fluid supply pipe 5. The valve 33 is also closed. Therefore, by driving the circulation pump 24, the hot water in the hot water tank 25 circulates through the three-way switching valve 29, the ejector 10 and the pipe line 32.

ジャケット部２内で加熱により蒸気の凝縮した復水と一部の蒸気は、排出管２０と２１を通って、エゼクタ１０に吸引され温水タンク２５に至る。   Condensate condensed with steam in the jacket portion 2 and a part of the steam are sucked into the ejector 10 through the discharge pipes 20 and 21 and reach the hot water tank 25.

温水タンク２５内の温水は、ヒートポンプ３の加熱部２８で所定温度まで加熱されることにより、タンク２５内で再蒸発してフラッシュ蒸気となり、フラッシュ蒸気管９からスチームエゼクタ１２に吸引され、蒸気供給管８からの蒸気と混合されてジャケット部２へ供給される。 The hot water in the hot water tank 25 is heated up to a predetermined temperature by the heating unit 28 of the heat pump 3, re-evaporates in the tank 25 to become flash steam, and is sucked into the steam ejector 12 from the flash steam pipe 9 to supply steam. It is mixed with the steam from the pipe 8 and supplied to the jacket part 2.
