解決しようとする課題は、冷却用循環通路に残留している循環流体の温度を精度良く所定値に維持することによって、加熱から冷却への切り換え時の温度制御性を向上させることである。   The problem to be solved is to improve the temperature controllability at the time of switching from heating to cooling by accurately maintaining the temperature of the circulating fluid remaining in the cooling circulation passage at a predetermined value.

本発明は、被熱交換物を加熱あるいは冷却する熱交換室を、加熱用あるいは冷却用の循環通路でエゼクタと連通して、当該エゼクタにタンクを介して循環ポンプと接続し、当該タンクに冷却流体を補給する冷却流体補給管を接続したものにおいて、冷却用循環通路の一部を分岐して補助冷却用循環通路を接続し、当該補助冷却用循環通路に切換弁を取り付けて熱交換室と接続したものである。   In the present invention, a heat exchange chamber for heating or cooling a heat exchange object is communicated with an ejector through a circulation path for heating or cooling, and the ejector is connected to a circulation pump via a tank, and the tank is cooled. In the case where a cooling fluid supply pipe for supplying fluid is connected, a part of the cooling circulation passage is branched to connect an auxiliary cooling circulation passage, and a switching valve is attached to the auxiliary cooling circulation passage, Connected.

本発明の加熱冷却装置は、冷却用循環通路の一部を分岐して補助冷却用循環通路を接続したことにより、この補助冷却用循環通路から、冷却用循環通路と同一温度の冷却流体を、すなわち、精度良く所定温度値に維持された循環流体を、熱交換室へ供給することができ、加熱から冷却への切り換え時の温度制御性を向上させることができる。   The heating and cooling device of the present invention branches a part of the cooling circulation passage and connects the auxiliary cooling circulation passage, so that the cooling fluid having the same temperature as the cooling circulation passage can be supplied from the auxiliary cooling circulation passage. That is, the circulating fluid that is accurately maintained at the predetermined temperature value can be supplied to the heat exchange chamber, and the temperature controllability at the time of switching from heating to cooling can be improved.

本発明は、冷却用循環通路の一部を分岐して補助冷却用循環通路を接続し、当該補助冷却用循環通路に切換弁を取り付けて熱交換室と接続したものであるが、補助冷却用循環通路に取り付ける切換弁は、三方向の通路を切り換えることのできる三方切換弁を用いることが望ましい。   In the present invention, a part of the cooling circulation passage is branched to connect the auxiliary cooling circulation passage, and a switching valve is attached to the auxiliary cooling circulation passage and connected to the heat exchange chamber. As the switching valve attached to the circulation passage, it is desirable to use a three-way switching valve that can switch the passage in three directions.

本実施例においては、熱交換室として加熱や冷却を行う反応釜１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スチームや、冷却源としての冷却水によって加熱あるいは冷却するものである。   In a present Example, the example using the reaction kettle 1 which heats and cools as a heat exchange chamber is shown. A heat exchange object (not shown) placed in the reaction kettle 1 is heated or cooled by steam as a heating source supplied to the jacket portion 2 or cooling water as a cooling source.

反応釜１のほぼ全周にわたりジャケット部２を形成し、ジャケット部２の右下部に排出管１９を取り付けてエゼクタ６と接続する。排出管１９には、開閉弁２０と、蒸気は排出することがなく復水だけを自動的に出口側へ排出することのできる蒸気トラップ２１を並行に配置して、エゼクタ６のノズル部１２の吸引部と接続する。エゼクタ６のディフューザ部７をタンク８に接続する。タンク８の側方を循環通路９で循環ポンプ１０と接続し、更に管路１１でエゼクタ６のノズル部１２と連通する。   A jacket portion 2 is formed over substantially the entire circumference of the reaction kettle 1, and a discharge pipe 19 is attached to the lower right portion of the jacket portion 2 and connected to the ejector 6. In the discharge pipe 19, an on-off valve 20 and a steam trap 21 that does not discharge steam but can automatically discharge only condensate to the outlet side are arranged in parallel. Connect with suction part. The diffuser part 7 of the ejector 6 is connected to the tank 8. A side of the tank 8 is connected to a circulation pump 10 through a circulation passage 9, and further communicates with a nozzle portion 12 of the ejector 6 through a pipe 11.

管路１１を分岐して補助冷却用循環通路３を接続する。この補助冷却用循環通路３には、ジャケット部２へ供給する冷却流体の温度を任意に制御するための冷却流体熱交換器５を取り付ける。冷却流体熱交換器５は、加熱あるいは冷却用の流体を供給管２２から供給することによって、内部を通過する冷却流体の温度を任意に制御することができるものである。   The pipeline 11 is branched to connect the auxiliary cooling circulation passage 3. A cooling fluid heat exchanger 5 for arbitrarily controlling the temperature of the cooling fluid supplied to the jacket portion 2 is attached to the auxiliary cooling circulation passage 3. The cooling fluid heat exchanger 5 can arbitrarily control the temperature of the cooling fluid passing through the inside by supplying a heating or cooling fluid from the supply pipe 22.

補助冷却用循環通路３とジャケット部２の間に切換弁としての三方切換弁４を配置する。三方切換弁４の下部口に管路１４を接続して、管路１４の下端部をエゼクタ６と連通する。三方切換弁４は、補助冷却用循環通路３とジャケット部２を連通する通路と、補助冷却用循環通路３と管路１４を連通する通路とを順次、切り換えることができるものである。   A three-way switching valve 4 as a switching valve is disposed between the auxiliary cooling circulation passage 3 and the jacket portion 2. A pipe 14 is connected to the lower port of the three-way switching valve 4, and the lower end of the pipe 14 is communicated with the ejector 6. The three-way switching valve 4 can sequentially switch between a passage communicating the auxiliary cooling circulation passage 3 and the jacket portion 2 and a passage communicating the auxiliary cooling circulation passage 3 and the pipe line 14.

タンク８内の冷却水等の液体が循環ポンプ１０で循環され、管路１１からエゼクタ６のノズル部１２を通ってタンク８内へと循環すると共に、補助冷却用循環通路３と三方切換弁４及び管路１４を通ってエゼクタ６に吸引され循環する。タンク８の左側上部には、冷却流体補給管１３を接続する。   Liquid such as cooling water in the tank 8 is circulated by the circulation pump 10 and circulates from the pipe line 11 through the nozzle portion 12 of the ejector 6 into the tank 8, and the auxiliary cooling circulation passage 3 and the three-way switching valve 4. And it is sucked into the ejector 6 through the conduit 14 and circulated. A cooling fluid supply pipe 13 is connected to the upper left side of the tank 8.

反応釜１のジャケット部２に、加熱用の蒸気供給管１５を接続する。蒸気供給管１５には供給する蒸気の圧力を制御するための圧力制御弁１７を取り付ける。また、循環ポンプ１０の吐出側には、余剰流体排出管２３を接続して、タンク８内の液位を所定範囲に維持することができるようにする。   A steam supply pipe 15 for heating is connected to the jacket portion 2 of the reaction kettle 1. A pressure control valve 17 for controlling the pressure of the supplied steam is attached to the steam supply pipe 15. Further, an excess fluid discharge pipe 23 is connected to the discharge side of the circulation pump 10 so that the liquid level in the tank 8 can be maintained within a predetermined range.

反応釜1内の図示しない被熱交換物を加熱する場合は、蒸気供給管１５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内の被熱交換物に熱を与えて加熱する。加熱により蒸気の凝縮した復水及び凝縮しなかった蒸気の一部は、排出管１９と蒸気トラップ２１あるいは開閉弁２０を通ってエゼクタ６に吸引されタンク８に至る。   When heating a heat exchange material (not shown) in the reaction kettle 1, the steam is supplied from the steam supply pipe 15 to the jacket portion 2 so that the steam is heated in the reaction kettle 1. Heat to. Condensate condensed with steam by heating and part of the steam not condensed are sucked into the ejector 6 through the discharge pipe 19 and the steam trap 21 or the opening / closing valve 20 and reach the tank 8.

一方、反応釜１内の被熱交換物を冷却する場合は、循環ポンプ１０を駆動して補助冷却用循環通路３内の冷却流体を三方切換弁４からジャケット部２へ供給すると共に、エゼクタ６にも冷却流体を供給してエゼクタ６で吸引力を発生させることにより、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、冷却流体が反応釜１内の被熱交換物の熱を奪って蒸発することにより、その蒸発潜熱によって被熱交換物を気化冷却することができるものである。   On the other hand, when cooling the heat exchanged material in the reaction kettle 1, the circulation pump 10 is driven to supply the cooling fluid in the auxiliary cooling circulation passage 3 from the three-way switching valve 4 to the jacket portion 2, and the ejector 6. In addition, the cooling fluid is supplied to the ejector 6 to generate a suction force so that the inside of the jacket portion 2 is brought into a predetermined pressure state, for example, a vacuum state equal to or lower than the atmospheric pressure. By removing the heat of the heat exchanged material and evaporating it, the heat exchanged material can be vaporized and cooled by the latent heat of vaporization.

このように、加熱から冷却へと切り換える場合に、補助冷却用循環通路３内の冷却流体を優先的にジャケット部２へ供給することによって、タンク８及び循環通路９と同一温度の冷却流体を、すなわち、精度良く所定温度値に維持された循環流体を、ジャケット部２へ供給することができ、温度制御性を向上させることができる。   In this way, when switching from heating to cooling, the cooling fluid in the auxiliary cooling circulation passage 3 is preferentially supplied to the jacket portion 2, so that the cooling fluid having the same temperature as the tank 8 and the circulation passage 9 is obtained. That is, the circulating fluid that is accurately maintained at the predetermined temperature value can be supplied to the jacket portion 2, and the temperature controllability can be improved.

ジャケット部２で被冷却物の熱を奪って蒸発気化した気化蒸気及び冷却流体の残りは、開閉弁２０並びに蒸気トラップ２１からエゼクタ６に吸引されタンク８に至る。 The vaporized vapor and the remainder of the cooling fluid evaporated and evaporated by taking the heat of the object to be cooled in the jacket portion 2 are sucked into the ejector 6 from the on-off valve 20 and the steam trap 21 and reach the tank 8.

補助冷却用循環通路３に取り付けた冷却流体熱交換器５によって、補助冷却用循環通路３からジャケット部２へ供給する冷却流体の温度を更に精度良く所定温度に維持することができる。   The cooling fluid heat exchanger 5 attached to the auxiliary cooling circulation passage 3 can maintain the temperature of the cooling fluid supplied from the auxiliary cooling circulation passage 3 to the jacket portion 2 at a predetermined temperature with higher accuracy.
