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、間接式の熱交換手段を介在して、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、上記熱交換手段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段目の吸引口を熱交換手段の蒸気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 a two-stage system as a suction means through an indirect heat exchange means in a waste steam passage through which the waste steam flows. A jet scrubber is connected to connect the first stage suction port of the two-stage jet scrubber to the liquid outlet of the heat exchange means, and the second stage suction port of the two-stage jet scrubber is a heat exchange means. Connected to the steam outlet.

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、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、熱交換手段の蒸気出口から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 of the present invention heat-condenses a part of the waste steam by heat exchange means to condense it into condensate, and sucks it from the liquid outlet to the first suction port of the two-stage jet scrubber. The amount of waste steam sucked from the steam outlet of the heat exchange means to the suction port of the two-stage jet scrubber can be reduced, and the amount of cooling water discharged by the jet scrubber can be greatly reduced. And the temperature of the mixed fluid of cooling water can be kept relatively high.

本発明の廃蒸気回収装置の実施例を示す構成図。The block diagram which shows the Example of the waste steam recovery apparatus of this invention.

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に接続した熱交換手段２、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, the waste steam recovery apparatus is composed of a waste steam passage 1, a heat exchange means 2 connected to the waste steam passage 1, and a two-stage jet scrubber 4 as a suction means. Constitute.

廃蒸気通路１に接続した熱交換手段２を、密閉状のタンク３と、冷却水供給管７、及び、冷却水排出管５とで間接式の熱交換手段として構成して、廃蒸気通路１からタンク３内へ供給される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 configured as an indirect heat exchange means with a sealed tank 3, a cooling water supply pipe 7, and a cooling water discharge pipe 5, and the waste steam passage 1 From this, a part of the waste steam supplied into the tank 3 can be condensed to condensate.

タンク３の右側側方に蒸気出口８を設けて、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、タンク３の下端部に液体出口９を設けて、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 steam outlet 8 is provided on the right side of the tank 3 to communicate with the second suction port 10 of the two-stage jet scrubber 4, and a liquid outlet 9 is provided at the lower end of the tank 3 to form a two-stage type. The jet scrubber 4 communicates with the first stage suction port 11.

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のタンク３内で一部が凝縮されて復水となり、その復水は液体出口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蒸気出口８から２段目の吸引口１０へ吸引される。 The waste steam that flows down from the left to the right in the waste steam passage 1 is partially condensed in the tank 3 of the heat exchange means 2 to become condensate, and the condensate is supplied from the liquid outlet 9 to the first suction port 11. And the water-separated steam is sucked from the steam outlet 8 to the second-stage suction port 10.

このように、熱交換手段２の蒸気出口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。   Thus, the amount of waste steam sucked from the steam outlet 8 of the heat exchange means 2 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 reduced. Therefore, the temperature of the mixed fluid of the waste steam and the cooling water discharged from the hot water discharge pipe 15 can be kept relatively high.
