本発明は、熱交換室内で被熱交換物を直接に又は間接に熱交換して、被熱交換物を冷却する冷却装置に関する。 The present invention relates to a cooling device that cools a heat exchange object by directly or indirectly exchanging the heat exchange object in a heat exchange chamber.
冷却装置は、熱交換室を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すると共に、当該タンクへ冷却水を供給することによるタンク内水温の制御部を設けることによって、蒸気の急凝縮に起因するハンマー現象に伴う振動や衝撃を防止することができるものである。 The cooling device communicates the heat exchange chamber with an ejector, connects the ejector to the circulation pump via a tank, and provides a tank water temperature control unit by supplying cooling water to the tank. It is possible to prevent vibrations and shocks associated with the hammer phenomenon caused by the rapid condensation of water.
この冷却装置においては、冷却温度の切り換え時に、所定の冷却温度に時間遅れなく速やかに制御することができず、その結果として冷却装置の温度制御性を悪化させる問題があった。これは、冷却温度を切り換える時に、冷却のための所定の温度状態に変更するために時間を要してしまうためである。
解決しようとする課題は、冷却温度の切り換え時の時間遅れを極力少なくして、冷却装置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 of the cooling device by minimizing the time delay when switching the cooling temperature.
本発明は、被熱交換物を冷却する熱交換室を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、熱交換室に冷却用真空タンクを接続して、当該冷却用真空タンクの下端に管路を介してエゼクタに接続すると共に、当該管路に急速自動開閉弁を取り付けて、被熱交換物を冷却する場合は、急速自動開閉弁を開弁して、あらかじめ所定の真空状態に維持した冷却用真空タンクと接続することにより、冷却水が被熱交換物の熱を奪って蒸発することで、被熱交換物を時間遅れなく気化冷却するものである。 In the present invention, a heat exchange chamber for cooling a heat exchange object is communicated with an ejector, and the ejector is connected to a circulation pump via a tank, and a cooling fluid supply pipe for supplying a cooling fluid is connected to the tank. In addition, a cooling vacuum tank is connected to the heat exchange chamber and connected to an ejector via a pipe line at the lower end of the cooling vacuum tank, and a quick automatic on-off valve is attached to the pipe line, When cooling the water, the rapid automatic on-off valve is opened and connected to a cooling vacuum tank that has been maintained in a predetermined vacuum state in advance, so that the cooling water takes the heat of the heat exchanged material and evaporates. The material to be heat-exchanged is vaporized and cooled without time delay .
本発明の冷却装置は、熱交換室に冷却用真空タンクを接続したことにより、この冷却用真空タンクをあらかじめ、所定の真空状態に維持しておくことによって、冷却用真空タンクと熱交換室を連通すると直ちに、熱交換室を所定の真空状態へと切り換えることができ、時間遅れなく冷却温度を切り換えることができる。 The cooling device of the present invention connects the cooling vacuum tank and the heat exchange chamber by connecting the cooling vacuum tank to the heat exchange chamber and maintaining the cooling vacuum tank in a predetermined vacuum state in advance. Immediately after communication, the heat exchange chamber can be switched to a predetermined vacuum state, and the cooling temperature can be switched without time delay.
本発明は、熱交換室に冷却用真空タンクを接続するものであるが、これらのタンクの容積や形状は、熱交換室の容積や、タンクと熱交換室との配管接続状況等に応じて適宜設計することができる。 In the present invention, a cooling vacuum tank is connected to the heat exchange chamber. The volume and shape of these tanks depend on the volume of the heat exchange chamber, the pipe connection status between the tank and the heat exchange chamber, and the like. It can be designed as appropriate.
本実施例においては、熱交換室として冷却を行う反応釜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、反応釜１のジャケット部２へ供給する冷却源としての冷却水によって冷却するものである。 In the present embodiment, an example using a reaction kettle 1 that performs cooling as a heat exchange chamber is shown. A heat exchange material (not shown) placed inside the reaction kettle 1 is cooled by cooling water as a cooling source supplied to the jacket portion 2 of the reaction kettle 1.
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、蒸気の凝縮した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を並列に配置して、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 almost the entire circumference of the reaction kettle 1, and a discharge pipe 19 is attached to the lower 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 the condensed condensate of steam to the outlet side are arranged in parallel. The suction part of the nozzle part 12 is connected. 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を分岐して冷却用流体供給通路３を接続する。この冷却用流体供給通路３には、ジャケット部２へ供給する冷却流体の流量を任意に制御するための制御弁５を取り付ける。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、冷却用流体供給通路３を通ってジャケット部２へ供給されるものである。なお、タンク８の上部には、冷却流体補給管１３を接続する。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。 The pipe 11 is branched and the cooling fluid supply passage 3 is connected. A control valve 5 for arbitrarily controlling the flow rate of the cooling fluid supplied to the jacket portion 2 is attached to the cooling fluid supply passage 3. A 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 through the cooling fluid supply passage 3 to the jacket portion. 2 is supplied. A cooling fluid supply pipe 13 is connected to the upper part of the tank 8. 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.
ジャケット部２の左側面に、管路１４を介して冷却用真空タンク１６を接続する。冷却用真空タンク１６の下端は、管路１８を介してエゼクタ６のノズル部１２と接続する。なお、管路１４には、急速自動開閉弁２２を取り付ける。 A cooling vacuum tank 16 is connected to the left side surface of the jacket portion 2 through a conduit 14. The lower end of the cooling vacuum tank 16 is connected to the nozzle portion 12 of the ejector 6 via a pipe line 18. A rapid automatic opening / closing valve 22 is attached to the pipeline 14.
反応釜１のジャケット部２の上面に、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と、加熱用流体タンク２４と、急速自動開閉弁２５を順次に取り付ける。加熱用流体タンク２４の内部には、蒸気供給管１５から所定圧力すなわち温度の蒸気が供給され、急速自動開閉弁２５を閉弁している場合は所定温度の蒸気が溜め置かれているものである。 A steam supply pipe 15 for heating is connected to the upper surface of the jacket portion 2 of the reaction kettle 1. A pressure control valve 17 for controlling the pressure of the supplied steam, a heating fluid tank 24, and a rapid automatic opening / closing valve 25 are sequentially attached to the steam supply pipe 15. Steam of a predetermined pressure, that is, temperature is supplied from the steam supply pipe 15 into the heating fluid tank 24, and when the rapid automatic opening / closing valve 25 is closed, steam of a predetermined temperature is stored. is there.
加熱用流体タンク２４の下端を、管路２６を介してエゼクタ６のノズル部１２と接続する。管路２６には、蒸気トラップ２７と開閉弁２８を並列に取り付ける。 The lower end of the heating fluid tank 24 is connected to the nozzle portion 12 of the ejector 6 through a pipe line 26. A steam trap 27 and an on-off valve 28 are attached to the pipe line 26 in parallel.
反応釜1内の図示しない被熱交換物を加熱する場合は、急速自動開閉弁２５を開弁して加熱用流体タンク２４内の加熱に適した温度の蒸気をジャケット部２へ急速に供給することによって、被熱交換物を時間遅れなく加熱することができる。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 the heat exchanged material (not shown) in the reaction kettle 1, the rapid automatic on-off valve 25 is opened to rapidly supply steam at a temperature suitable for heating in the heating fluid tank 24 to the jacket portion 2. As a result, the heat exchange object can be heated without time delay. 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.
加熱に代えて反応釜１内の被熱交換物を冷却する場合は、循環ポンプ１０を駆動して冷却用流体供給通路３からジャケット部２へ冷却流体すなわち冷却水を供給すると共に、急速自動開閉弁２２を開弁して、あらかじめ所定の真空状態に維持した冷却用真空タンク１６とジャケット部２を接続することにより、冷却水が被熱交換物の熱を奪って蒸発することで、被熱交換物を気化冷却することができる。 When the heat exchanged material in the reaction kettle 1 is cooled instead of heating, the circulating pump 10 is driven to supply the cooling fluid, that is, the cooling water from the cooling fluid supply passage 3 to the jacket portion 2, and the rapid automatic opening and closing. By opening the valve 22 and connecting the jacket 2 with the cooling vacuum tank 16 that is maintained in a predetermined vacuum state in advance, the cooling water takes the heat of the heat exchanged material and evaporates, thereby The exchange can be vaporized and cooled.
このように、加熱と冷却の切り換え時に、加熱用流体タンク２４と冷却用真空タンク１６とを切り換えることによって、時間遅れなく加熱と冷却を切り換えることができ、加熱冷却装置の温度制御性を向上させることができる。 Thus, by switching between the heating fluid tank 24 and the cooling vacuum tank 16 at the time of switching between heating and cooling, heating and cooling can be switched without time delay, and the temperature controllability of the heating and cooling device is improved. be able to.
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.
