By providing the heat exchange container 1 with the separate steam pipe 5 for supplying the separate steam and the control valve 6, the steam separated from a steam which is originally condensed, is supplied to the heat exchange container 1, so that a temperature of the temperature-raised fluid discharged from the temperature-raised fluid discharge pipe 9 can be arbitrarily controlled.

Description

本発明は、各種蒸気使用装置で使用されて残った蒸気や、蒸気の凝縮した高温復水から発生した再蒸発蒸気などを、水等の冷却流体で熱交換して凝縮させることによって、モヤモヤと立ち込める蒸気を無くしたり、あるいは、冷却流体を熱交換して温度上昇した温水を別途使用して蒸気の保有熱を有効利用するものに関する。 In the present invention, the remaining steam used in various steam-using devices and the re-evaporated steam generated from the high-temperature condensate condensed with heat are heat-exchanged with a cooling fluid such as water to condense. The present invention relates to an apparatus that effectively uses the heat retained in steam by eliminating steam that can be trapped or by separately using hot water whose temperature has been increased by heat exchange of a cooling fluid.

従来の熱交換装置は、蒸気供給口を有する熱回収室に冷却管を内設し、この熱回収室に大気開放部を連通して、大気開放部と熱回収室の下部に凝縮液を貯溜させることにより、熱回収室内へ不凝縮気体、例えば空気等、が流入することを防止して効率良く熱交換することができるものである。 In the conventional heat exchange device, a cooling pipe is installed in a heat recovery chamber having a steam supply port, and an air opening portion is communicated with the heat recovery chamber, and condensate is stored in the air opening portion and the lower portion of the heat recovery chamber. By doing so, non-condensable gas such as air can be prevented from flowing into the heat recovery chamber and heat can be exchanged efficiently.

この熱交換装置においては、蒸気と熱交換して発生した温水の温度を、任意にコントロールすることができないために、温水の利用箇所が非常に限定された箇所だけとなってしまい、多くの温水を廃棄せざるを得なくなってしまう問題があった。これは、熱交換すべく蒸気の発生量が一定でないために、蒸気で加熱される温水の温度が不安定になるためである。 In this heat exchange device, the temperature of the hot water generated by exchanging heat with steam cannot be arbitrarily controlled, so that the location where the hot water is used is limited to a very limited amount. There was a problem that had to be discarded. This is because the temperature of the hot water heated by the steam becomes unstable because the amount of steam generated for heat exchange is not constant.

解決しようとする課題は、蒸気と熱交換して発生する温水の温度を、任意にコントロールすることができるようにして、温水を廃棄することなく幅広い用途に利用できる熱交換装置を提供すること。 The problem to be solved is to provide a heat exchanging device that can be used for a wide range of applications without discarding the hot water by arbitrarily controlling the temperature of the hot water generated by exchanging heat with steam.

本発明は、熱交換容器の内部に冷却流体管を取り付けて、当該冷却流体管に冷却流体を供給すると共に、冷却流体管の外周に蒸気を供給して、蒸気を冷却流体で熱交換することによって凝縮させ、昇温した冷却流体を系外へ排出する昇温流体排出管を設けたものにおいて、熱交換容器に別途の蒸気を供給する別途蒸気管を接続すると共に、当該別途蒸気管に供給する蒸気量を制御することのできる制御弁を取り付けたものである。 The present invention provides a cooling fluid pipe attached to the inside of a heat exchange container, supplies a cooling fluid to the cooling fluid pipe, supplies steam to the outer periphery of the cooling fluid pipe, and heat-exchanges the steam with the cooling fluid. In addition to connecting a separate steam pipe for supplying a separate steam to the heat exchange vessel, and supplying the same to the separate steam pipe It is equipped with a control valve that can control the amount of steam.

本発明の熱交換装置は、熱交換容器に別途の蒸気を供給する別途蒸気管と制御弁を取り付けたことによって、本来凝縮すべく蒸気とは別途の蒸気を熱交換容器へ供給して、昇温流体排出管から排出される昇温流体の温度を任意にコントロールすることができる。従って、昇温流体を廃棄することなく幅広い用途に利用することができる。 The heat exchange device of the present invention is provided with a separate steam pipe and a control valve for supplying separate steam to the heat exchange container, thereby supplying steam separate from steam to the heat exchange container to be originally condensed. The temperature of the heated fluid discharged from the warm fluid discharge pipe can be arbitrarily controlled. Therefore, the temperature rising fluid can be used for a wide range of applications without being discarded.

本発明の熱交換装置は、熱交換容器に別途の蒸気を供給する別途蒸気管を接続するものであるが、この別途蒸気管は、熱交換容器の容積に応じて１本のみならず、複数本を取り付けることもできる。 The heat exchange device of the present invention connects a separate steam pipe for supplying a separate steam to the heat exchange container. The number of the separate steam pipes is not limited to one depending on the volume of the heat exchange container. Books can also be attached.

熱交換容器１に接続した蒸気供給管２及び冷却流体供給管３と、熱交換容器１の中央に取り付けた大気開放管４と、大気開放管４の外周に配置した冷却流体管８、及び、熱交換容器１の上部に接続した別途蒸気管５とで熱交換装置を構成する。 A steam supply pipe 2 and a cooling fluid supply pipe 3 connected to the heat exchange container 1, an atmosphere release pipe 4 attached to the center of the heat exchange container 1, a cooling fluid pipe 8 disposed on the outer periphery of the atmosphere release pipe 4, and A heat exchange apparatus is constituted by a separate steam pipe 5 connected to the upper part of the heat exchange vessel 1.

蒸気供給管２は、図示しない蒸気使用装置の出口側や高温復水の再蒸発タンク等と接続して、凝縮すべく蒸気を熱交換容器１内に供給する。熱交換容器１内の中央部に円筒パイプ状の大気開放管４を設ける。大気開放管４の外周に、銅製長尺パイプをコイル状に形成した冷却流体管８を配置して、冷却流体管８の下部入口側を冷却流体供給管３と接続すると共に、上部出口側は昇温流体排出管９と接続する。蒸気供給管２から熱交換容器１内に供給された凝縮すべく蒸気が冷却流体管８の外表面と接触して熱交換され凝縮するものである。 The steam supply pipe 2 is connected to an outlet side of a steam using device (not shown), a high-temperature condensate re-evaporation tank or the like, and supplies steam into the heat exchange container 1 for condensation. A cylindrical pipe-shaped open air pipe 4 is provided at the center in the heat exchange vessel 1. A cooling fluid pipe 8 in which a copper long pipe is formed in a coil shape is arranged on the outer periphery of the atmosphere opening pipe 4, and the lower inlet side of the cooling fluid pipe 8 is connected to the cooling fluid supply pipe 3, and the upper outlet side is It connects with the temperature rising fluid discharge pipe 9. In order to condense, the steam supplied from the steam supply pipe 2 into the heat exchange vessel 1 contacts the outer surface of the cooling fluid pipe 8 to exchange heat and condense.

熱交換容器１の上部に接続した別途蒸気管５に、供給する蒸気量を制御することのできる制御弁６を取り付ける。別途蒸気管５は、下方の蒸気供給管２から熱交換容器１へ供給される凝縮すべく蒸気とは別途の蒸気を熱交換容器１へ供給するものである。別途蒸気管５から熱交換容器１へ供給される別途の蒸気は、冷却流体管８で冷却流体と熱交換して昇温させるものである。 A control valve 6 capable of controlling the amount of steam to be supplied is attached to a separate steam pipe 5 connected to the upper part of the heat exchange vessel 1. The separate steam pipe 5 supplies steam, which is separate from the steam supplied to the heat exchange container 1 from the lower steam supply pipe 2 to the heat exchange container 1 for condensation. The separate steam supplied from the separate steam pipe 5 to the heat exchange vessel 1 is heated by exchanging heat with the cooling fluid in the cooling fluid pipe 8.

冷却流体管８の上部出口側に接続した昇温流体排出管９に、この昇温流体排出管９内の昇温流体の温度を検出する温度センサ７を取り付ける。また、温度センサ７は、別途蒸気管５に取り付けた制御弁６と電気的に接続する。 A temperature sensor 7 for detecting the temperature of the temperature rising fluid in the temperature rising fluid discharge pipe 9 is attached to the temperature rising fluid discharge pipe 9 connected to the upper outlet side of the cooling fluid pipe 8. The temperature sensor 7 is electrically connected to a control valve 6 attached to the steam pipe 5 separately.

蒸気供給管２から熱交換容器１内へ供給される蒸気は、冷却流体管８で冷却されて凝縮することにより復水となり、熱交換容器１の下側部１０に溜まる。この熱交換容器１の下側部１０に滞留している復水の水位が、排出管１１の上端部を越えると、排出管１１を通って復水は外部へ排出される。 The steam supplied from the steam supply pipe 2 into the heat exchange container 1 is condensed by being cooled by the cooling fluid pipe 8 and condensed in the lower portion 10 of the heat exchange container 1. When the water level of the condensate remaining in the lower portion 10 of the heat exchange container 1 exceeds the upper end of the discharge pipe 11, the condensate is discharged to the outside through the discharge pipe 11.

昇温流体排出管９から排出される昇温流体の温度を任意にコントロールするには、温度センサ７で昇温流体の温度を検出して、この検出温度が所定値よりも低い場合は、別途蒸気管５に取り付けた制御弁６の弁開度を大きくして供給する別途蒸気量を増大させることによって、昇温流体排出管９から排出される昇温流体の温度を上昇させることができる。一方、温度センサ７での検出温度が所定値よりも高い場合は、制御弁６の弁開度を小さくして供給する別途蒸気量を減少させるか、あるいは、制御弁６を全閉状態にすることによって、昇温流体の温度を降下させることができる。 In order to arbitrarily control the temperature of the temperature rising fluid discharged from the temperature rising fluid discharge pipe 9, the temperature of the temperature rising fluid is detected by the temperature sensor 7. The temperature of the heated fluid discharged from the heated fluid discharge pipe 9 can be increased by increasing the amount of additional steam supplied by increasing the valve opening degree of the control valve 6 attached to the steam pipe 5. On the other hand, when the temperature detected by the temperature sensor 7 is higher than the predetermined value, the opening amount of the control valve 6 is reduced to reduce the amount of additional steam supplied, or the control valve 6 is fully closed. As a result, the temperature of the temperature rising fluid can be lowered.

本発明は、蒸気と熱交換して発生する昇温流体の温度を任意にコントロールして、昇温流体を廃棄することなく幅広い用途に利用できる熱交換装置として利用することができる。 INDUSTRIAL APPLICABILITY The present invention can be used as a heat exchanging apparatus that can be used for a wide range of applications without arbitrarily discarding the temperature rising fluid by arbitrarily controlling the temperature of the temperature rising fluid generated by heat exchange with steam.
