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回収することによって、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 can eliminate waste steam that can be trapped in the inside or outside of a factory building by collecting waste steam that is discarded from various steam-using devices such as shrink tunnels, steamers, and rubber vulcanizers. The present invention relates to a waste steam recovery device.

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、瞬間的に且つ大量に発生する廃蒸気の全てを確実に吸引することができない問題があった。また、瞬間的に且つ大量に発生する廃蒸気を確実に吸引するためには、真空吸引手段を構成する循環ポンプの容量を大きなものとしなければならず、装置自身のコストが上昇すると共に、循環ポンプの駆動にも多くの電力を要するためにランニングコストが上昇してしまう問題があった。
特開２００２−５５８２号公報 In this waste steam recovery apparatus, there is a problem that it is impossible to reliably suck all of the waste steam generated instantaneously and in large quantities. Also, in order to reliably suck the waste steam generated instantaneously and in large quantities, the capacity of the circulation pump that constitutes the vacuum suction means must be increased, which increases the cost of the apparatus itself and increases the circulation. Since a lot of electric power is required for driving the pump, there is a problem that the running cost increases.
Japanese Patent Laid-Open No. 2002-5582

解決しようとする課題は、瞬間的に且つ大量に発生する廃蒸気を確実に吸引することのできる安価な廃蒸気回収装置を提供すること。   The problem to be solved is to provide an inexpensive waste steam recovery apparatus capable of reliably sucking waste steam generated instantaneously and in large quantities.

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所定の真空圧力状態に維持された真空タンクを連通すると共に、当該真空タンクに蒸気エゼクタの吸引口を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 communicates a vacuum tank maintained in a predetermined vacuum pressure state with a waste steam passage through which the waste steam flows, and the vacuum tank This is connected to the suction port of the steam ejector.

本発明の廃蒸気回収装置は、所定の圧力状態に維持された真空タンクを連通したことによって、廃蒸気が瞬間的に且つ大量に発生した場合、この真空タンクで廃蒸気の全てを確実に吸引することができ、一部の廃蒸気がモヤモヤと立ち昇ることを防止することができる。   The waste steam recovery device of the present invention reliably sucks all of the waste steam in this vacuum tank when waste steam is generated instantaneously and in large quantities by communicating with a vacuum tank maintained at a predetermined pressure state. It is possible to prevent some waste steam from rising.

本発明は、所定の圧力状態に維持された真空タンクを用いるものであるが、真空タンクの圧力状態と容積は、発生する廃蒸気の量、あるいは、単位時間当りの廃蒸気の発生量に応じて、適宜選定することができる。   The present invention uses a vacuum tank maintained at a predetermined pressure state. The pressure state and volume of the vacuum tank depend on the amount of waste steam generated or the amount of waste steam generated per unit time. Can be selected as appropriate.

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に接続した真空タンク２、及び、蒸気エゼクタ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 passage 1, the vacuum tank 2 connected to the waste steam passage 1, and the steam ejector 4 constitute a waste steam recovery device.

廃蒸気通路１の左端部に、円錐状の廃蒸気収集口３を設ける。廃蒸気収集口３の下方に、図示しない蒸気装置を配置する。蒸気装置で発生した廃蒸気が、廃蒸気収集口３から吸引されるものである。   A conical waste steam collection port 3 is provided at the left end of the waste steam passage 1. A steam device (not shown) is disposed below the waste steam collection port 3. Waste steam generated in the steam device is sucked from the waste steam collection port 3.

廃蒸気通路１の途中にバルブ８を介在して真空タンク２を配置する。真空タンク２は、中空円筒状で、上部に廃蒸気通路１の下端を接続する。一方、真空タンク２の下部に連通管５と蒸気・復水タンク６と接続管７を介して蒸気エゼクタ４の吸引口１０と連通する。   A vacuum tank 2 is disposed in the middle of the waste steam passage 1 with a valve 8 interposed. The vacuum tank 2 has a hollow cylindrical shape, and the lower end of the waste steam passage 1 is connected to the upper part. On the other hand, the lower part of the vacuum tank 2 communicates with the suction port 10 of the steam ejector 4 through the communication pipe 5, the steam / condensate tank 6, and the connection pipe 7.

蒸気エゼクタ４は、吸引口１０とディフューザ部１１で構成して、吸引口１０側にエゼクタ駆動用の高圧蒸気を供給する高圧蒸気管１２を接続すると共に、ディフューザ部１１の出口側に中圧蒸気管１３を接続して、別途の図示しない中圧蒸気使用箇所へと連通する。  The steam ejector 4 is composed of a suction port 10 and a diffuser unit 11, and a high-pressure steam pipe 12 that supplies high-pressure steam for driving the ejector is connected to the suction port 10 side, and an intermediate-pressure steam is connected to the outlet side of the diffuser unit 11. The pipe 13 is connected to communicate with a separate medium pressure steam use location (not shown).

蒸気エゼクタ４に接続管７を介して接続した蒸気・復水タンク６は、横長のパイプ状のものであり、上部に接続管７並びに連通管５を接続する。蒸気・復水タンク６の下部には、蒸気の凝縮した復水だけを外部へ排出する蒸気トラップ１４を取り付ける。  The steam / condensate tank 6 connected to the steam ejector 4 via a connection pipe 7 is a horizontally long pipe, and the connection pipe 7 and the communication pipe 5 are connected to the upper part. At the lower part of the steam / condensate tank 6, a steam trap 14 for discharging only condensate condensed with steam to the outside is attached.

真空タンク２から蒸気・復水タンク６内へ流下した廃蒸気は、蒸気エゼクタ４の吸引口１０へ吸引され、高圧蒸気と混合されて中圧蒸気管１３から別途の蒸気使用箇所へと供給されると共に、蒸気・復水タンク６内の一部が熱を奪われて凝縮して復水となって、蒸気トラップ１４から外部へ排出されるものである。  Waste steam that has flowed from the vacuum tank 2 into the steam / condensate tank 6 is sucked into the suction port 10 of the steam ejector 4, mixed with high-pressure steam, and supplied from the intermediate-pressure steam pipe 13 to a separate steam use location. At the same time, a part of the steam / condensate tank 6 is deprived of heat, condenses into condensate, and is discharged from the steam trap 14 to the outside.

蒸気エゼクタ４へ高圧蒸気管１２から駆動用の高圧蒸気を供給することによって、蒸気エゼクタ４の吸引口１０で所定の真空吸引力を発生することにより、真空タンク２内を所定の圧力状態に維持することができる。廃蒸気収集口３の下方で、大量の廃蒸気が瞬間的に発生した場合は、廃蒸気通路１のバルブ８を全開することによって、大量の廃蒸気は所定の圧力状態、すなわち、大気圧以下の真空圧力状態に維持された真空タンク２内へ、廃蒸気の全てが速やかに吸引される。  By supplying high-pressure steam for driving from the high-pressure steam pipe 12 to the steam ejector 4, a predetermined vacuum suction force is generated at the suction port 10 of the steam ejector 4, thereby maintaining the inside of the vacuum tank 2 at a predetermined pressure state. can do. When a large amount of waste steam is instantaneously generated below the waste steam collection port 3, the valve 8 of the waste steam passage 1 is fully opened, so that the large amount of waste steam is in a predetermined pressure state, that is, below atmospheric pressure. All of the waste steam is quickly sucked into the vacuum tank 2 maintained in the vacuum pressure state.

上記のように本発明は、廃蒸気通路１に真空タンク２を配置したことにより、モヤモヤと立ち昇る廃蒸気を無くすことができる。   As described above, by disposing the vacuum tank 2 in the waste steam passage 1, the present invention can eliminate the waste steam rising up.
