It is related with the waste steam recovery device which can eliminate.
廃蒸気回収装置は、蒸気使用装置としてのシュリンクトンネルと、エゼクターと液体タンクと循環ポンプで構成された真空吸引手段とを、廃蒸気回収パイプで接続したもので、シュリンクトンネルからの廃蒸気を真空吸引手段で吸引することによって、モヤモヤと立ち込める廃蒸気を無くすことができるものである。 The waste steam recovery unit is a shrink tunnel that uses steam, and vacuum suction means that consists of an ejector, a liquid tank, and a circulation pump connected by a waste steam recovery pipe. By sucking with the sucking means, it is possible to eliminate waste steam that can get trapped.
この廃蒸気回収装置においては、エゼクターのノズル部で大量の冷却水を吐出しなければならず、エゼクター内で混合された廃蒸気と冷却水の混合流体の温度が低くなってしまい、この混合流体の使用用途が限られてしまう問題があった。 In this waste steam recovery device, a large amount of cooling water must be discharged from the nozzle part of the ejector, and the temperature of the mixed fluid of waste steam and cooling water mixed in the ejector becomes low, and this mixed fluid There was a problem that the usage of was limited.
解決しようとする課題は、廃蒸気と冷却水の混合流体の温度を比較的高く維持することのできる廃蒸気回収装置を提供すること。 The problem to be solved is to provide a waste steam recovery device that can maintain the temperature of the mixed fluid of waste steam and cooling water at a relatively high temperature.
本発明は、蒸気装置から流下してくる廃蒸気を所定箇所へ排出するものにおいて、廃蒸気の流下する廃蒸気通路に、熱交換手段と気液分離器を介在して、吸引手段としての２段式ジェットスクラバーを接続して、当該２段式ジェットスクラバーの１段目の吸引口を、上記気液分離器の液体出口に接続すると共に、２段式ジェットスクラバーの２段目の吸引口を気液分離器の気体出口と接続して、２段式ジェットスクラバーの出口側に温水タンクを接続したものである。 According to the present invention, waste steam flowing down from a steam device is discharged to a predetermined location. A heat exchange means and a gas-liquid separator are interposed in a waste steam passage through which the waste steam flows, and 2 as a suction means. Connect the stage jet scrubber, connect the first stage suction port of the two stage jet scrubber to the liquid outlet of the gas-liquid separator, and connect the second stage suction port of the two stage jet scrubber It is connected to the gas outlet of the gas-liquid separator and a hot water tank is connected to the outlet side of the two-stage jet scrubber.
本発明の廃蒸気回収装置は、熱交換手段で廃蒸気の一部を熱交換して凝縮させて復水とし、気液分離器の液体出口から２段式ジェットスクラバーの１段目の吸引口へ吸引することによって、気液分離器の気体出口から２段式ジェットスクラバーの吸引口へ吸引される廃蒸気の量が少なくなり、ジェットスクラバーで吐出する冷却水の量を大幅に減少することができ、したがって、廃蒸気と冷却水の混合流体の温度を比較的高く維持することができる。 The waste steam recovery apparatus according to the present invention heat-condenses a part of waste steam by heat exchange means to condense it into condensate, and from the liquid outlet of the gas-liquid separator, the first stage suction port of the two-stage jet scrubber Can reduce the amount of waste steam sucked from the gas outlet of the gas-liquid separator to the suction port of the two-stage jet scrubber, and can greatly reduce the amount of cooling water discharged by the jet scrubber.

廃蒸気通路１に接続した熱交換手段２を、冷却水注入管５とインラインミキサー６で構成する。冷却水注入管５には冷却水供給管７を接続すると共に、図示はしないが、冷却水供給管７の冷却水注入管５側端部には冷却水噴射ノズルを取り付けて、廃蒸気通路１から供給される廃蒸気に冷却水を噴射して、廃蒸気の一部を凝縮させて復水にさせることができるものである。 The heat exchange means 2 connected to the waste steam passage 1 is composed of a cooling water injection pipe 5 and an in-line mixer 6. A cooling water supply pipe 7 is connected to the cooling water injection pipe 5, and although not shown, a cooling water injection nozzle is attached to the end of the cooling water supply pipe 7 on the cooling water injection pipe 5 side, and the waste steam passage 1. The cooling water is jetted onto the waste steam supplied from the water, and a part of the waste steam is condensed to be condensed water.
冷却水注入管５の出口側にインラインミキサー６を接続する。このインラインミキサー６は、冷却水注入管５から供給される廃蒸気と冷却水の混合流体を螺旋状に流下させることによって、混合流体の更なる混合を促進することができるものである。 An in-line mixer 6 is connected to the outlet side of the cooling water injection pipe 5. The in-line mixer 6 can promote further mixing of the mixed fluid by causing the mixed fluid of the waste steam and the cooling water supplied from the cooling water injection pipe 5 to flow down spirally.
インラインミキサー６の出口側に気液分離器３を接続する。この気液分離器３は、インラインミキサー６から供給される蒸気と冷却水と復水の混合流体を、旋回流とすることによって、気体としての蒸気と、液体としての水とに気液分離することができるものである。 The gas-liquid separator 3 is connected to the outlet side of the in-line mixer 6. This gas-liquid separator 3 gas-liquid separates into the vapor | steam as gas and the water as a liquid by making into a swirl | flow the mixed fluid of the vapor | steam supplied from the in-line mixer 6, cooling water, and condensate. It is something that can be done.
気液分離器３の右側側方に気体出口８を取り付けて、２段式ジェットスクラバー４の２段目の吸引口１０と連通し、また、気液分離器３の下端部に液体出口９を取り付けて、２段式ジェットスクラバー４の１段目の吸引口１１と連通する。 A gas outlet 8 is attached to the right side of the gas-liquid separator 3 to communicate with the second-stage suction port 10 of the two-stage jet scrubber 4, and a liquid outlet 9 is connected to the lower end of the gas-liquid separator 3. It attaches and communicates with the first stage suction port 11 of the two-stage jet scrubber 4.
２段式ジェットスクラバー４は、１段目のジェットスクラバー１２と２段目のジェットスクラバー１３を直列に配置したもので、１段目のジェットスクラバー１２の上部に高圧水供給管１４を接続すると共に、２段目のジェットスクラバー１３の下部出口側に温水排出管１５を接続する。 The two-stage jet scrubber 4 includes a first-stage jet scrubber 12 and a second-stage jet scrubber 13 arranged in series. A high-pressure water supply pipe 14 is connected to the upper part of the first-stage jet scrubber 12. A hot water discharge pipe 15 is connected to the lower outlet side of the second-stage jet scrubber 13.
温水排出管１５を、温水タンク１６の下部と接続する。円筒状の温水タンク１６の内部下方に平板状のメッシュ板１７，１８を取り付ける。このメッシュ板１７，１８には、小径の貫通孔を多数設けて、温水排出管１５から温水タンク１６内へ供給される復水と冷却水及び廃蒸気に混入していた空気との混合流体を、温水タンク１６内の温水１９と効率良く熱交換することができるようにする。 The hot water discharge pipe 15 is connected to the lower part of the hot water tank 16. Flat mesh plates 17 and 18 are attached to the lower side of the cylindrical hot water tank 16. The mesh plates 17 and 18 are provided with a large number of small-diameter through holes, and a mixed fluid of condensate supplied from the hot water discharge pipe 15 into the hot water tank 16 and air mixed in the cooling water and the waste steam. Then, heat exchange with the hot water 19 in the hot water tank 16 can be performed efficiently.

An air discharge pipe 22 is connected to the upper surface of the hot water tank 16.
廃蒸気通路１を左から右方向へ流下する廃蒸気は、冷却水注入管５で一部が凝縮されて復水となり、インラインミキサー６で更に混合を促進されて、気液分離器３で気液が分離され、分離された復水と冷却水は液体出口９から１段目の吸引口１１へ吸引されると共に、水の分離された蒸気は気体出口８から２段目の吸引口１０へ吸引される。 A part of the waste steam flowing down from the left to the right in the waste steam passage 1 is condensed in the cooling water injection pipe 5 to become condensate, further mixed by the in-line mixer 6, and then separated by the gas-liquid separator 3. The liquid is separated, and the separated condensate and cooling water are sucked from the liquid outlet 9 to the first stage suction port 11, and the water-separated vapor is fed from the gas outlet 8 to the second stage suction port 10. Sucked.
このように、気液分離器３の気体出口８から２段目の吸引口１０へ吸引される廃蒸気の量が少なくなり、ジェットスクラバー４で吐出する高圧水としての冷却水の量を大幅に減少することができ、したがって、温水排出管１５から排出される廃蒸気と冷却水の混合流体の温度を比較的高く維持することができる。 In this way, the amount of waste steam sucked from the gas outlet 8 of the gas-liquid separator 3 to the second-stage suction port 10 is reduced, and the amount of cooling water as high-pressure water discharged by the jet scrubber 4 is greatly increased. Therefore, the temperature of the mixed fluid of waste steam and cooling water discharged from the hot water discharge pipe 15 can be kept relatively high.
