The supplied steam is supplied toward the bottom surface of the flat plate-shaped heat exchange container. After colliding with the bottom surface, the steam is dispersed and supplied into the heat exchange container, so that the entire heat exchange surface is made uniform. Can be heated.
本発明は、加熱流体供給管の熱交換容器側端部を、水平状の熱交換面とは反対側に開口するものであるが、開口する位置は、熱交換容器の形状に応じて適宜選定することができる。 In the present invention, the end portion of the heating fluid supply pipe on the side of the heat exchange container is opened on the side opposite to the horizontal heat exchange surface, but the opening position is appropriately selected according to the shape of the heat exchange container. can do.
図1において、円筒状で平板状の熱交換容器1と、この熱交換容器1の上端面に水平状に形成した熱交換面2と、熱交換容器1の内部へ蒸気を供給する加熱流体供給管3、及び、熱交換容器1の下方に連通した吸引手段6とで蒸気加熱装置を構成する。 In FIG. 1, a cylindrical and flat plate heat exchange vessel 1, a heat exchange surface 2 formed horizontally on the upper end surface of the heat exchange vessel 1, and a heating fluid supply for supplying steam to the inside of the heat exchange vessel 1 The steam heating device is constituted by the pipe 3 and the suction means 6 communicating below the heat exchange vessel 1.
加熱流体供給管3には、熱交換容器1へ供給する蒸気の量を制御するための制御弁7を取り付ける。加熱流体供給管3の熱交換容器1側端部23を、熱交換容器1のほぼ中央部で、水平状の熱交換面2とは反対側の底面20に向けて開口する。この熱交換容器1側端部23から、熱交換容器1の底面20へ向けて蒸気が供給されることで、熱交換容器1内へ分散して蒸気が供給されるものである。 A control valve 7 for controlling the amount of steam supplied to the heat exchange container 1 is attached to the heating fluid supply pipe 3. The end portion 23 of the heating fluid supply pipe 3 on the side of the heat exchange container 1 is opened toward the bottom surface 20 on the opposite side of the horizontal heat exchange surface 2 at the substantially central portion of the heat exchange container 1. Steam is supplied from the end portion 23 on the side of the heat exchange container 1 toward the bottom surface 20 of the heat exchange container 1 so that the steam is dispersed and supplied into the heat exchange container 1.
熱交換容器1に冷却水を供給する冷却水供給管5を接続して、熱交換容器1を冷却することもできるようにする。冷却水供給管5の下端は吸引手段6の一部と接続する。冷却水供給管5には、水エゼクタ11と自動弁12を介在して、熱交換容器1の内部と接続する。自動弁12が開弁することにより、熱交換容器1の内部へ冷却水が供給されるものである。冷却水供給管5の熱交換容器1側端部21には、冷却水を熱交換面2側へ噴射することのできる噴射ノズルを取り付けることが望ましい。 A cooling water supply pipe 5 for supplying cooling water to the heat exchange container 1 is connected so that the heat exchange container 1 can be cooled. The lower end of the cooling water supply pipe 5 is connected to a part of the suction means 6. The cooling water supply pipe 5 is connected to the inside of the heat exchange vessel 1 through a water ejector 11 and an automatic valve 12. When the automatic valve 12 is opened, cooling water is supplied into the heat exchange container 1. It is desirable to attach an injection nozzle capable of injecting cooling water to the heat exchange surface 2 side at the end portion 21 of the cooling water supply pipe 5 on the heat exchange container 1 side.
冷却水供給管5に取り付けた水エゼクタ11の吸込室には蒸気供給管16を接続する。水エゼクタ11内を流下する冷却水に、蒸気供給管16から加熱用の蒸気を供給することで、熱交換容器1へ供給する冷却水の温度を調節することができるものである。 A steam supply pipe 16 is connected to the suction chamber of the water ejector 11 attached to the cooling water supply pipe 5. By supplying the heating steam from the steam supply pipe 16 to the cooling water flowing down in the water ejector 11, the temperature of the cooling water supplied to the heat exchange container 1 can be adjusted.
冷却水供給管5に取り付けた自動弁12と並列に、冷却水循環弁18を取り付ける。冷却水循環弁18は、熱交換容器1を冷却する場合に常時、微少開弁しておき、自動弁12が閉弁しても、少しの冷却水を熱交換容器1内へ供給して、冷却水の一部を絶えず循環するものである。 A cooling water circulation valve 18 is attached in parallel with the automatic valve 12 attached to the cooling water supply pipe 5. The cooling water circulation valve 18 always opens slightly when the heat exchange container 1 is cooled, and even if the automatic valve 12 is closed, a little cooling water is supplied into the heat exchange container 1 for cooling. A part of the water circulates constantly.
熱交換容器1の円弧状の底面20から管路8によりスチームトラップ4の入口側と接続する。スチームトラップ4と並列に開閉弁9を取り付ける。スチームトラップ4と開閉弁9の出口側は、吸引手段6を構成する液体エゼクタ13の吸込室10と接続する。 The arc-shaped bottom surface 20 of the heat exchange vessel 1 is connected to the inlet side of the steam trap 4 by a pipe line 8. An on-off valve 9 is attached in parallel with the steam trap 4. The outlet side of the steam trap 4 and the on-off valve 9 is connected to the suction chamber 10 of the liquid ejector 13 constituting the suction means 6.
吸引手段6を、液体エゼクタ13と冷却水タンク14と循環ポンプ15とで構成する。循環ポンプ15の駆動によって、冷却水タンク14内の冷却水を液体エゼクタ13へ供給して吸込室10で所定の吸引力を発生すると共に、冷却水供給管5から熱交換容器1へ冷却水を供給するものである。 The suction means 6 includes a liquid ejector 13, a cooling water tank 14, and a circulation pump 15. By driving the circulation pump 15, the cooling water in the cooling water tank 14 is supplied to the liquid ejector 13 to generate a predetermined suction force in the suction chamber 10, and the cooling water is supplied from the cooling water supply pipe 5 to the heat exchange container 1. To supply.
冷却水タンク14の上部に、冷却水補給管30を接続すると共に、循環ポンプ15の吐出側の管路を分岐して余剰水排出管17を接続する。 A cooling water supply pipe 30 is connected to the upper part of the cooling water tank 14, and a pipe on the discharge side of the circulation pump 15 is branched to connect an excess water discharge pipe 17.
熱交換面2を加熱する場合は、加熱流体供給管3と制御弁7から熱交換容器1内へ所定量の蒸気を供給することによって、蒸気によって加熱される。加熱流体供給管3の熱交換容器1側端部23を、水平状の熱交換面2とは反対側の底面20に向けて開口したことで、熱交換容器1内へ分散して蒸気が供給され、加熱温度ムラを防止して、熱交換面2の全体を均一に加熱することができる。
加熱により蒸気の凝縮した復水は、熱交換容器1下端の管路8からスチームトラップ4を通り、更に、液体エゼクタ13から冷却水タンク14へと至る。
When heating the heat exchange surface 2, the heat exchange surface 2 is heated by steam by supplying a predetermined amount of steam from the heating fluid supply pipe 3 and the control valve 7 into the heat exchange container 1. By opening the end portion 23 of the heating fluid supply pipe 3 on the heat exchange container 1 side toward the bottom surface 20 on the side opposite to the horizontal heat exchange surface 2, the steam is dispersed and supplied into the heat exchange container 1. Thus, uneven heating temperature can be prevented and the entire heat exchange surface 2 can be heated uniformly.
Condensate condensed with steam by heating passes from the pipe line 8 at the lower end of the heat exchange vessel 1 through the steam trap 4 and further from the liquid ejector 13 to the cooling water tank 14.
一方、熱交換面2を冷却する場合は、冷却水供給管5の自動弁12を開弁して熱交換面2の底面へ冷却水を供給することによって、熱交換面2の熱により冷却水が蒸発気化して、その蒸発潜熱でもって冷却することで、冷却効率を向上することができる。
気化した蒸気と、気化し切れなかった冷却水は、管路8から開閉弁9を通り、更に、液体エゼクタ13から冷却水タンク14へと至る。
On the other hand, when cooling the heat exchange surface 2, the automatic valve 12 of the cooling water supply pipe 5 is opened and the cooling water is supplied to the bottom surface of the heat exchange surface 2, so that the cooling water is cooled by the heat of the heat exchange surface 2. Evaporates and cools with the latent heat of vaporization, so that the cooling efficiency can be improved.
The vaporized vapor and the cooling water that has not been vaporized pass from the conduit 8 through the on-off valve 9 and further from the liquid ejector 13 to the cooling water tank 14.
