本発明は、熱交換室内で被熱交換物を間接的に熱交換して、被熱交換物を加熱する熱交換装置に関する。   The present invention relates to a heat exchange apparatus that indirectly heat-exchanges a heat exchange object in a heat exchange chamber to heat the heat exchange object.

熱交換装置は、熱交換室をエゼクタと連通して、当該エゼクタに共通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、加熱から冷却への切り換えを短時間に且つ温度ムラなく実施することができるものである。   The heat exchange device communicates the heat exchange chamber with the ejector, connects the ejector to the circulation pump via a common tank, and provides a control unit for the water temperature in the tank by supplying cooling water to the tank. Switching from heating to cooling can be performed in a short time and without temperature unevenness.

この熱交換装置においては、加熱を終えた被熱交換物を乾燥する場合に、被熱交換物を別途の乾燥機へ移し変えなければならず、生産効率が低下すると共に、熱交換装置と乾燥機の設置スペースがかさむ問題があった。
特開２００２−３１４５０号公報 In this heat exchange device, when drying the heat exchanged material after heating, the heat exchanged material must be transferred to a separate dryer, resulting in a decrease in production efficiency and the drying of the heat exchange device. There was a problem that the installation space of the machine increased.
JP 2002-31450 A

解決しようとする課題は、１台の熱交換装置で乾燥もできるようにして、生産効率の向上を図ると共に、装置の設置スペースも小さなものとすることのできる熱交換装置を得ることである。   The problem to be solved is to obtain a heat exchanging apparatus that can be dried by one heat exchanging apparatus to improve the production efficiency and can reduce the installation space of the apparatus.

本発明は、被熱交換物を収納する収納部を設けて、当該収納部の外周に熱交換室を配置し、当該熱交換室に熱交換流体供給管を接続すると共に、熱交換室をエゼクタと接続して、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、熱交換流体供給管を加熱用の蒸気源に接続すると共に、収納部の内部とエゼクタの吸引口を連通管で連通したものである。   The present invention provides a storage section for storing a heat exchange object, arranges a heat exchange chamber on the outer periphery of the storage section, connects a heat exchange fluid supply pipe to the heat exchange chamber, and ejects the heat exchange chamber to an ejector. The heat exchanging fluid supply pipe is connected to the heating steam source in the case where the ejector is connected to the circulation pump via the tank, and the cooling fluid supply pipe for supplying the cooling fluid is connected to the tank. In addition, the inside of the storage unit and the suction port of the ejector are communicated with each other through a communication pipe.

本発明の熱交換装置は、収納部の内部とエゼクタの吸引口を連通したことにより、加熱を終えた被熱交換物の収納された収納部内部を、エゼクタの吸引口で生じる吸引力でもって吸引することにより、被熱交換物の保有する水分を吸引して被熱交換物を乾燥することができる。   The heat exchanging device of the present invention communicates the inside of the storage unit and the suction port of the ejector so that the inside of the storage unit in which the heated heat exchanged material is stored has a suction force generated at the suction port of the ejector. By sucking, it is possible to suck the water held by the heat exchange material and dry the heat exchange material.

本発明は、被熱交換物を加熱し、且つ、乾燥することができるものであるが、加熱と乾燥をそれぞれ単独で実施することも、あるいは、両者を並行して実施することもできるものである。   The present invention can heat and dry the heat-exchanged material, but the heating and drying can be carried out independently or both can be carried out in parallel. is there.

本実施例においては、熱交換室として加熱を行う反応釜１のジャケット部２を用いた例を示す。収納部としての反応釜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に熱交換流体供給管３から供給する加熱源としての蒸気によって加熱するものである。   In the present embodiment, an example is shown in which a jacket portion 2 of a reaction kettle 1 that performs heating as a heat exchange chamber is used. A heat exchange material (not shown) placed inside the reaction kettle 1 serving as a storage portion is heated by steam as a heating source supplied from the heat exchange fluid supply pipe 3 to the jacket portion 2.

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の吸引口と接続する。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 to the suction port. 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.

本実施例においては、加熱のみならず冷却もできるようにするために、管路１１を分岐して冷却水供給管３を接続する。この冷却水供給管３には、ジャケット部２へ供給する冷却水の温度を任意に制御するための冷却水熱交換器５を取り付ける。冷却水熱交換器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水の温度を任意に制御することができるものである。   In the present embodiment, the cooling water supply pipe 3 is connected by branching the pipe 11 so that not only heating but also cooling can be performed. A cooling water heat exchanger 5 for arbitrarily controlling the temperature of the cooling water supplied to the jacket portion 2 is attached to the cooling water supply pipe 3. The cooling water heat exchanger 5 can arbitrarily control the temperature of the cooling water passing through the inside by supplying a heating or cooling fluid from the supply pipe 22.

冷却水供給管３とジャケット部２の間に、供給する冷却水の量を調節することのできる調節弁４を配置する。   Between the cooling water supply pipe 3 and the jacket portion 2, an adjustment valve 4 that can adjust the amount of cooling water to be supplied is disposed.

収納部としての反応釜１内部の上部と、エゼクタ６のノズル部１２の吸引口を、連通管１４で接続する。連通管１４に取り付けた蒸気凝縮器１８には、冷却水供給管２４と冷却水排出管２５を接続して、連通管１４内を流下する蒸気を冷却して凝縮させることができるようにする。   The upper part inside the reaction vessel 1 as a storage part and the suction port of the nozzle part 12 of the ejector 6 are connected by a communication pipe 14. The steam condenser 18 attached to the communication pipe 14 is connected to a cooling water supply pipe 24 and a cooling water discharge pipe 25 so that the steam flowing down in the communication pipe 14 can be cooled and condensed.

タンク８内の冷却水が循環ポンプ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、冷却水供給管３と調節弁４を通ってジャケット部２へも供給される。タンク８の左側上部には、冷却水補給管１３を接続する。   Cooling water in the tank 8 is circulated by the circulation pump 10 and circulates from the pipe line 11 through the nozzle part 12 of the ejector 6 into the tank 8 and through the cooling water supply pipe 3 and the regulating valve 4 to the jacket part. 2 is also supplied. A cooling water 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、加熱用の蒸気源と接続した熱交換流体供給管１５を接続する。熱交換流体供給管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、余剰水排出管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 heat exchange fluid supply pipe 15 connected to a heating steam source 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 heat exchange fluid supply pipe 15. Further, an excess water 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蒸気によって加熱する場合は、熱交換流体供給管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、加熱用の蒸気が反応釜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 with steam, by supplying steam at a temperature suitable for heating from the heat exchange fluid supply pipe 15 to the jacket portion 2, the heating steam is converted into the reaction kettle. Heat the heat-exchanged material in 1 by applying heat. 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を駆動して冷却水供給管３内の冷却水を調節弁４からジャケット部２へ供給することによって、反応釜１を冷却することができる。この場合、更に、エゼクタ６にも冷却水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、供給された冷却水が反応釜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 water in the cooling water supply pipe 3 from the control valve 4 to the jacket portion 2, whereby the reaction kettle 1 Can be cooled. In this case, further, by supplying cooling water to the ejector 6 and generating suction force by the ejector 6, the inside of the jacket portion 2 is brought into a predetermined pressure state, for example, a vacuum state below atmospheric pressure, The supplied cooling water takes the heat of the heat exchange material in the reaction kettle 1 and evaporates, whereby the heat exchange material can be vaporized and cooled by the latent heat of vaporization.

加熱の後、連通管１４から反応釜１内を吸引することによって、反応釜１内の被熱交換物の保有している水分が吸引され、被熱交換物を乾燥することができる。   After the heating, the inside of the reaction kettle 1 is sucked from the communication pipe 14, whereby the water held by the heat exchange material in the reaction kettle 1 is sucked and the heat exchange material can be dried.
