Description
本発明は、蒸気使用機器で発生した蒸気の凝縮水としての復水を、ボイラーや給水タンク等の所定の復水回収先へ回収する復水回収装置に関する。 The present invention relates to a condensate recovery apparatus that recovers condensate as condensate of steam generated in a steam-using device to a predetermined condensate recovery destination such as a boiler or a water supply tank.
従来の復水回収装置は、蒸気使用機器の復水出口側を蒸気トラップと復水集合タンクと逆止弁を介して復水圧送部材に接続し、この復水圧送部材の高圧操作流体排出口に圧力制御弁を取り付けたもので、熱エネルギー損失を少なくすることができるものである。 In the conventional condensate recovery device, the condensate outlet side of the steam-using device is connected to the condensate pumping member via the steam trap, the condensate collecting tank, and the check valve, and the high-pressure operation fluid discharge port of the condensate pumping member A pressure control valve is attached to the tube, and heat energy loss can be reduced.
この復水回収装置においては、回収する復水が高温・高圧である場合に、復水回収管の内部で多量の再蒸発蒸気を発生して、復水回収管内の圧力を上昇させ、復水の流下に必要な差圧が確保できなくなり、回収すべき復水の流量が低下してしまう問題があった。 In this condensate recovery device, when the condensate to be recovered is high temperature and high pressure, a large amount of re-evaporated steam is generated inside the condensate recovery pipe to increase the pressure in the condensate recovery pipe, Therefore, there is a problem that the required differential pressure cannot be secured and the flow rate of condensate to be recovered decreases.
解決しようとする課題は、復水回収管内の再蒸発蒸気量を低減させて、回収すべき復水の流量が低下することのない復水回収装置を提供すること。 The problem to be solved is to provide a condensate recovery device that reduces the amount of re-evaporated steam in the condensate recovery pipe so that the flow rate of the condensate to be recovered does not decrease.
本発明は、蒸気使用機器で蒸気が凝縮して発生した高温・高圧の復水を、復水回収管から復水回収ポンプによって所定の復水回収先へ回収するものにおいて、復水回収管と復水回収ポンプの間に復水溜タンクを配置して、当該復水溜タンクの上部から再蒸発管をインゼクタの駆動蒸気口と接続し、当該インゼクタの給水口に冷水供給管を接続して、当該インゼクタの吐出口を復水回収管の内部と連通したものである。 The present invention recovers high-temperature and high-pressure condensate generated by condensing steam in a steam-using device from a condensate recovery pipe to a predetermined condensate recovery destination by a condensate recovery pump. A condensate tank is arranged between the condensate recovery pumps, a re-evaporation pipe is connected to the drive steam port of the injector from the upper part of the condensate tank, and a cold water supply pipe is connected to the water supply port of the injector. The injector discharge port communicates with the inside of the condensate recovery pipe.
本発明の復水回収装置は、復水溜タンクの上部から再蒸発管をインゼクタの駆動蒸気口と接続し、インゼクタの給水口に冷水供給管を接続して、インゼクタの吐出口を復水回収管の内部と連通したことにより、インゼクタの給水口から供給される給水が、インゼクタの駆動蒸気口から供給される駆動蒸気により加圧され、高圧の給水となってインゼクタの吐出口から復水回収管の内部へ供給されることで、復水回収管内の再蒸発蒸気を凝縮させて、復水回収管内の圧力を低下させ、回収すべき復水の流量の低下を防止することができる。 The condensate recovery apparatus of the present invention connects the re-evaporation pipe from the upper part of the condensate reservoir tank to the drive steam port of the injector, connects the cold water supply pipe to the water supply port of the injector, and connects the discharge port of the injector to the condensate recovery pipe The water supply supplied from the injector water supply port is pressurized by the drive steam supplied from the injector drive steam port, and becomes a high-pressure water supply from the injector discharge port to the condensate recovery pipe. By being supplied to the inside, the re-evaporated steam in the condensate recovery pipe is condensed, the pressure in the condensate recovery pipe is reduced, and the flow rate of the condensate to be recovered can be prevented from being lowered.
本発明の復水回収装置は、インゼクタの吐出口から復水回収管の内部へ高圧の給水を噴射するものであるが、この噴射部には、多孔部材や噴射ノズル等を取り付けることができる。 The condensate recovery apparatus of the present invention injects high-pressure water supply into the condensate recovery pipe from the discharge port of the injector, and a porous member, an injection nozzle or the like can be attached to the injection part.
図１は本実施例の構成図であって、復水回収管１と、復水溜タンク２と、復水回収ポンプ４と、インゼクタ５とで復水回収装置を構成する。 FIG. 1 is a configuration diagram of this embodiment, and a condensate recovery apparatus is constituted by a condensate recovery pipe 1, a condensate reservoir tank 2, a condensate recovery pump 4, and an injector 5.
復水回収管１の左端部は、図示しない蒸気使用機器と接続して、この蒸気使用機器で発生した復水が、復水回収管１から復水溜タンク２へ流入するものである。復水溜タンク２の下部を管路６によって復水回収ポンプ４のエゼクタ７の吸引口８と接続する。復水回収ポンプ４を、エゼクタ７と循環ポンプ９、及び、両者を連通する循環路１０とで構成する。循環路１０の一部を分岐した分岐管１１を、復水回収先としての蒸気ボイラー１２に接続する。 The left end portion of the condensate recovery pipe 1 is connected to a steam using device (not shown), and condensate generated by the steam using device flows into the condensate tank 2 from the condensate recovery tube 1. The lower part of the condensate tank 2 is connected to the suction port 8 of the ejector 7 of the condensate recovery pump 4 by a pipe 6. The condensate recovery pump 4 includes an ejector 7, a circulation pump 9, and a circulation path 10 that communicates both. A branch pipe 11 branched from a part of the circulation path 10 is connected to a steam boiler 12 as a condensate recovery destination.
復水溜タンク２の上部から再蒸発管１３をインゼクタ５の駆動蒸気口と接続する。復水溜タンク２内の高温・高圧復水の一部が再蒸発して、再蒸発管１３からインゼクタ５の駆動蒸気口へと供給される。 The re-evaporation pipe 13 is connected to the drive steam port of the injector 5 from the upper part of the condensate tank 2. A part of the high-temperature / high-pressure condensate in the condensate tank 2 is re-evaporated and supplied from the re-evaporation pipe 13 to the drive steam port of the injector 5.
インゼクタ５の上部左側面の給水口に冷水供給管１４を接続する。冷水供給管１４の他端部は、蒸気ボイラー１２へ給水するための給水タンク１５の下部と接続することで、給水タンク１５の下部に溜まった冷水を冷水供給管１４からインゼクタ５の給水口へ供給するものである。 A cold water supply pipe 14 is connected to the water supply port on the upper left side of the injector 5. The other end of the cold water supply pipe 14 is connected to the lower part of the water supply tank 15 for supplying water to the steam boiler 12 so that the cold water accumulated in the lower part of the water supply tank 15 is transferred from the cold water supply pipe 14 to the water supply port of the injector 5. To supply.
インゼクタ５の吐出口１６に管路１７を接続して復水回収管１と連通する。復水回収管１内の復水は、復水溜タンク２から復水回収ポンプ４へ吸引され、更に、蒸気ボイラー１２へ供給される。復水回収管１内を流下する高温・高圧の復水は、復水回収管１内で多量に再蒸発するが、インゼクタ５の吐出口１６と管路１７から供給される噴射冷水により冷却され、再度、復水となって復水溜タンク２内へ流下する。 A pipe 17 is connected to the discharge port 16 of the injector 5 to communicate with the condensate recovery pipe 1. Condensate in the condensate recovery pipe 1 is sucked from the condensate reservoir 2 to the condensate recovery pump 4 and further supplied to the steam boiler 12. The high-temperature and high-pressure condensate flowing down in the condensate recovery pipe 1 is re-evaporated in a large amount in the condensate recovery pipe 1, but is cooled by the jet cold water supplied from the discharge port 16 and the pipe line 17 of the injector 5. Again, it becomes condensate and flows down into the condensate tank 2.
このように、復水回収管１内の再蒸発蒸気を冷水によって凝縮させて、復水回収管１内の圧力を低下させ、回収すべき復水の流量の低下を防止することができる。 Thus, the re-evaporated steam in the condensate recovery pipe 1 can be condensed with cold water, the pressure in the condensate recovery pipe 1 can be reduced, and the flow rate of the condensate to be recovered can be prevented from decreasing.
本発明は、蒸気使用機器で発生した蒸気の凝縮水としての復水を、ボイラーや給水タンク等の所定の復水回収先へ回収する復水回収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 recovery device that recovers condensate as condensate of steam generated in a steam-using device to a predetermined condensate recovery destination such as a boiler or a water supply tank.
