Description
本発明は、例えばシュリンクトンネルやスチーマーやゴムの加硫器等の各種蒸気使用装置から廃棄される廃蒸気を、熱交換して回収することにより、工場建屋の内部あるいは外部でモヤモヤと立ち込める廃蒸気を無くすことのできる廃蒸気回収装置に関する。 The present invention is, for example, waste steam discarded from various steam-using devices such as shrink tunnels, steamers, rubber vulcanizers, etc., and is recovered by exchanging heat so that it can be trapped inside and outside the factory building. 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、気化冷却式の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たものである。 The present invention discharges waste steam flowing down from a steam device to a predetermined location, and sucks it through a waste steam passage through which waste steam flows through a vapor-cooling heat exchange means and a gas-liquid separator. A two-stage jet scrubber is connected as a means, and the first stage suction port of the two-stage jet scrubber is connected to the liquid outlet of the gas-liquid separator and the second stage of the two-stage jet scrubber Is connected to the gas outlet of the gas-liquid separator.
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.
本実施例においては図１に示すように、廃蒸気通路１と、この廃蒸気通路１に接続した気化冷却式の熱交換手段２と気液分離器３、及び、吸引手段としての２段式ジェットスクラバー４とで廃蒸気回収装置を構成する。 In this embodiment, as shown in FIG. 1, a waste steam passage 1, a vaporization cooling type heat exchange means 2 and a gas-liquid separator 3 connected to the waste steam passage 1, and a two-stage type as a suction means. The jet scrubber 4 constitutes a waste steam recovery device.
廃蒸気通路１に接続した熱交換手段２は、二重管構造として、中央部５を廃蒸気通路１に接続すると共に、外周部６を気化冷却室とする。この気化冷却室６には冷却水供給管７を接続すると共に、管路１６を介して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。冷却水供給管７から気化冷却室６へ供給される冷却水が、中央部５を流下する廃蒸気から熱を奪って蒸発気化することによって、その気化潜熱でもっ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 exchanging means 2 connected to the waste steam passage 1 has a double pipe structure and connects the central portion 5 to the waste steam passage 1 and the outer peripheral portion 6 as a vaporization cooling chamber. A cooling water supply pipe 7 is connected to the evaporative cooling chamber 6 and communicates with the first stage suction port 11 of the two-stage jet scrubber 4 through a pipe line 16. The cooling water supplied from the cooling water supply pipe 7 to the evaporative cooling chamber 6 takes heat from the waste steam flowing down the central portion 5 and evaporates and vaporizes it, thereby condensing a part of the waste steam with the latent heat of vaporization. Can be made to condensate.
気化冷却室６で気化した蒸気と残った冷却水は、２段式ジェットスクラバー４の１段目の吸引口１１へ吸引される。 The vapor evaporated in the evaporative cooling chamber 6 and the remaining cooling water are sucked into the first-stage suction port 11 of the two-stage jet scrubber 4.
熱交換手段２の中央部５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、熱交換手段２から供給される蒸気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 central portion 5 of the heat exchange means 2. The gas-liquid separator 3 can perform gas-liquid separation into vapor as gas and water as liquid by turning the mixed fluid supplied from the heat exchange means 2 into a swirl flow. It 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 part of the second-stage jet scrubber 13.
廃蒸気通路１を左から右方向へ流下する廃蒸気は、熱交換手段２で一部が凝縮されて復水となり、気液分離器３で気液が分離され、分離された復水は液体出口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。 The waste steam flowing down from the left to the right in the waste steam passage 1 is partially condensed by the heat exchange means 2 to become condensate, and the gas-liquid is separated by the gas-liquid separator 3. The separated condensate is liquid While being sucked from the outlet 9 to the first stage suction port 11, the water-separated vapor is sucked from the gas outlet 8 to the second stage suction port 10.
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.
