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. Therefore, the temperature of the mixed fluid of waste steam and cooling water can be kept relatively high.
本発明は、2段式のジェットスクラバーを用いるものであるが、このジェットスクラバーは従来周知のものを適宜用いることができる。 In the present invention, a two-stage jet scrubber is used, and a conventionally known jet scrubber can be appropriately used.

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 the 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.
ジェットスクラバー4と温水タンク16の間で、温水排出管15の途中に気液分離部材26を配置する。気液分離部材26は、疎水性多孔質膜からなる中空長尺チューブを水平方向に多数本取り付けたもので、気体としての空気は透過して外部へ排出し、液体は透過することなく温水タンク16へ供給するものである。 Between the jet scrubber 4 and the hot water tank 16, a gas-liquid separation member 26 is disposed in the middle of the hot water discharge pipe 15. The gas-liquid separation member 26 has a large number of hollow long tubes made of a hydrophobic porous membrane attached in the horizontal direction. Air as a gas is permeated and discharged to the outside, and the liquid is not permeated. 16 is supplied.
温水タンク16の左側中段部に温水循環ポンプ23を接続し、その吐出管24にバルブ25を介在して高圧水供給管14と連通する。温水循環ポンプ23を駆動することで、温水タンク16内の温水を、ジェットスクラバー4の高圧駆動水とすることができるものである。 A hot water circulation pump 23 is connected to the left middle part of the hot water tank 16, and the discharge pipe 24 is connected to the high pressure water supply pipe 14 via a valve 25. By driving the hot water circulation pump 23, the hot water in the hot water tank 16 can be used as high-pressure drive water for the jet scrubber 4.
一方、温水タンク16の右側中段部に温水ポンプ20を接続して、その吐出管21を図示しない温水使用箇所と接続する。また、温水タンク16の上面には空気排出管22を接続する。 On the other hand, a hot water pump 20 is connected to the middle right portion of the hot water tank 16 and its discharge pipe 21 is connected to a hot water use location (not shown). 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.
