Description
本発明は、蒸気の凝縮した高温復水を、再蒸発タンク内で再蒸発させて蒸気として再度利用する復水の再蒸発装置に関する。 The present invention relates to a condensate re-evaporation device that re-evaporates high-temperature condensate with condensed steam and reuses it as steam in a re-evaporation tank.
従来の復水の再蒸発装置は、蒸気使用機器に蒸気を供給する蒸気供給管にエゼクタを介在し、蒸気使用機器の出口側にスチームトラップを介して再蒸発タンクを接続して、再蒸発タンクの上部をエゼクタと接続したもので、再蒸発タンクで高温復水から再蒸発した蒸気をエゼクタで吸引して有効活用することができるものである。 A conventional condensate re-evaporation device has an ejector interposed in a steam supply pipe for supplying steam to steam-using equipment, and a re-evaporation tank is connected to the outlet side of the steam-using equipment via a steam trap. The upper part is connected to an ejector, and the steam re-evaporated from the high-temperature condensate in the re-evaporation tank can be sucked with the ejector and effectively used.
この復水の再蒸発装置においては、再蒸発タンク内での復水の再蒸発量が不十分なために、再蒸発蒸気を確実に有効活用できていない問題があった。 This condensate re-evaporation apparatus has a problem that the re-evaporated steam cannot be effectively used because the amount of condensate re-evaporation in the re-evaporation tank is insufficient.
解決しようとする課題は、再蒸発タンク内での復水の再蒸発量を増やして、再蒸発蒸気を確実に有効活用することのできる復水の再蒸発装置を提供すること。 The problem to be solved is to provide a condensate re-evaporation device that increases the amount of re-evaporation of condensate in the re-evaporation tank and can reliably utilize re-evaporated steam.
本発明は、再蒸発タンクに復水供給管を接続して、当該再蒸発タンク内で高温復水の再蒸発した蒸気を吸引する吸引手段を接続したものにおいて、復水供給管を復水を溜め置く復水溜容器と、大気圧以下の真空状態に維持された再蒸発タンクを復水溜容器の上方へ配置して当該復水溜容器と再蒸発タンクを連通する連通管とで形成して、当該連通管の復水溜容器側端部にフロートを接続し、当該フロートによって連通管の復水溜容器側端部が復水溜容器内上面の高温復水中に開口したものである。 In the present invention, a condensate supply pipe is connected to a re-evaporation tank, and suction means for sucking re-evaporated steam of high-temperature condensate in the reevaporation tank is connected. A condensate reservoir to be stored, and a re-evaporation tank maintained in a vacuum state below atmospheric pressure are arranged above the condensate reservoir and formed with a communication pipe communicating the condensate reservoir and the reevaporation tank. A float is connected to the condensate container end of the communication pipe, and the condensate container end of the communication pipe opens into the high-temperature condensate on the upper surface of the condensate container.
本発明の復水の再蒸発装置は、復水溜容器と再蒸発タンクを連通する連通管の復水溜容器側端部にフロートを接続して、このフロートにより連通管の復水溜容器側端部が復水溜容器内上面の高温復水中に開口することによって、再蒸発タンク内へ上面の高温復水が優先的に供給され、再蒸発タンク内での復水の再蒸発量を増やして再蒸発蒸気を確実に有効活用することができる。 The condensate re-evaporation apparatus of the present invention has a float connected to the condensate container side end of the communication pipe that communicates the condensate reservoir and the reevaporation tank, and the end of the condensate container side of the communication pipe is connected by this float. By opening the high-temperature condensate in the upper surface of the condensate reservoir, the high-temperature condensate on the upper surface is preferentially supplied into the re-evaporation tank, and the amount of re-evaporation of the condensate in the re-evaporation tank is increased. Can be effectively utilized.
本発明の復水の再蒸発装置の連通管は、フロートが復水溜容器内上面を自由に浮上降下することができるように、弾力性のあるフレキシブルチューブを用いることが好適である。 The communication pipe of the condensate re-evaporating apparatus according to the present invention preferably uses an elastic flexible tube so that the float can freely float up and down the upper surface of the condensate reservoir.
図１において、再蒸発タンク１と復水溜容器２、この復水溜容器２と再蒸発タンク１を連通する連通管３と、吸引手段４、及び、蒸気タンク５とで復水の再蒸発装置を構成する。
In FIG. 1, a condensate re-evaporation apparatus is composed of a re-evaporation tank 1 and a condensate reservoir 2, a communication pipe 3 that communicates the condensate reservoir 2 and the re-evaporation tank 1, a suction means 4, and a
再蒸発タンク１は復水溜容器２の上方約９メートルの位置に配置して、連通管３で両者を連通する。連通管３の上端部６は再蒸発タンク１の上部に接続し、下端部７は復水溜容器２の復水の上面側と接続する。連通管３の下端部７には復水面に浮上する複数のフロート８を取り付ける。連通管３は、フロート８が復水面を自由に浮上降下することができるように、弾力性のあるフレキシブルチューブで製作する。連通管３と復水溜容器２とで復水供給管を構成する。復水溜容器２内は図示しない復水管から高温の復水が供給される。 The re-evaporation tank 1 is disposed at a position of about 9 meters above the condensate reservoir 2 and communicates with each other through a communication pipe 3. The upper end 6 of the communication pipe 3 is connected to the upper part of the re-evaporation tank 1, and the lower end 7 is connected to the upper surface side of the condensate reservoir 2. A plurality of floats 8 that float on the condensate surface are attached to the lower end portion 7 of the communication pipe 3. The communication pipe 3 is made of an elastic flexible tube so that the float 8 can freely rise and fall on the condensate surface. The communication pipe 3 and the condensate reservoir 2 constitute a condensate supply pipe. The condensate reservoir 2 is supplied with high-temperature condensate from a condensate pipe (not shown).
再蒸発タンク１の下部に、再蒸発タンク１内の残留復水を復水溜容器２内へ戻す復水戻し管９を接続する。再蒸発タンク１を管路１０によって、吸引手段４を構成する蒸気エゼクタ１１の吸引口１２と接続する。蒸気エゼクタ１１で発生する吸引力で再蒸発タンク１内を大気圧以下の真空状態とすることによって、復水溜容器２の上部の高温復水が再蒸発タンク１内へ吸引され、再蒸発タンク１内で高温復水が再蒸発して蒸気を発生する。再蒸発しなかった復水は、復水戻し管９から復水溜容器２内へ重力で流下する。 A condensate return pipe 9 for connecting residual condensate in the reevaporation tank 1 into the condensate reservoir 2 is connected to the lower part of the reevaporation tank 1. The reevaporation tank 1 is connected to a suction port 12 of a steam ejector 11 constituting the suction means 4 by a pipe 10. By setting the inside of the re-evaporation tank 1 to a vacuum state below atmospheric pressure by the suction force generated by the steam ejector 11, the high-temperature condensate at the top of the condensate reservoir 2 is sucked into the re-evaporation tank 1, and the re-evaporation tank 1 The hot condensate is re-evaporated and generates steam. Condensate that has not re-evaporated flows down from the condensate return pipe 9 into the condensate reservoir 2 by gravity.
吸引手段４を蒸気エゼクタ１１と水封式真空ポンプ１３で構成する。蒸気エゼクタ１１の出口側に水封式真空ポンプ１３を接続し、水封式真空ポンプ１３の出口側を管路１４により蒸気タンク５と接続する。蒸気タンク５の上部と、蒸気エゼクタ１１の入口を管路１５で接続する。
The suction means 4 is composed of a steam ejector 11 and a water ring vacuum pump 13. A water-sealed vacuum pump 13 is connected to the outlet side of the steam ejector 11, and the outlet side of the water-sealed vacuum pump 13 is connected to the
蒸気タンク５には、タンク５内へ蒸気を補給する蒸気補給管１６と、水を補給する水補給管１７を、それぞれ接続する。蒸気タンク５の上部には管路１８を介在して蒸気圧縮機１９を接続する。蒸気タンク５内の再蒸発蒸気が、蒸気圧縮機１９へ吸引されて昇圧し、出口管２０から図示しない蒸気使用箇所へと供給される。
A steam supply pipe 16 for supplying steam into the
蒸気エゼクタ１１を出た再蒸発蒸気は、水封式真空ポンプ１３で昇圧されて蒸気タンク５へ至り、一部が管路１５から蒸気エゼクタ１１へ供給され、残りの再蒸発蒸気は蒸気圧縮機１９から別途の蒸気使用箇所へと供給される。
The re-evaporated steam that has exited from the steam ejector 11 is boosted by the water-sealed vacuum pump 13 and reaches the
連通管３の下端部７にフロート８を接続して、このフロート８により連通管３の下端部７が復水溜容器２内上面の高温復水中に開口することによって、再蒸発タンク１内へ上面の高温復水が優先的に供給され、再蒸発タンク１内での復水の再蒸発量を増やして再蒸発蒸気を確実に有効活用することができる。 A float 8 is connected to the lower end portion 7 of the communication pipe 3, and the lower end portion 7 of the communication pipe 3 opens into the high temperature condensate on the upper surface of the condensate reservoir 2 by this float 8. The high-temperature condensate is preferentially supplied, and the amount of re-evaporation of the condensate in the re-evaporation tank 1 can be increased so that the re-evaporated steam can be effectively used.
本発明は、蒸気の凝縮した高温復水を、再蒸発タンク内で再蒸発させて蒸気として再度利用する復水の再蒸発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 condensate re-evaporation device in which high-temperature condensate condensed with steam is re-evaporated in a re-evaporation tank and reused as steam.
