Abstract
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、廃蒸気に混入した空気を循環ポンプが吸引してしまうことによって、ポンプ能力が低下してしまう問題があった。 In this waste steam recovery device, there is a problem that the pump capacity is lowered by the circulation pump sucking the air mixed in the waste steam.
解決しようとする課題は、循環ポンプが混入空気を吸引することのない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 in which the circulation pump does not suck in the mixed air.
本発明は、蒸気装置から流下してくる廃蒸気を熱交換器で冷却して蒸気を凝縮させるものにおいて、熱交換器の上部に空気排出弁を取り付けると共に、熱交換器の下部に電動ポンプと液体エゼクタを順次に接続して、当該液体エゼクタの吸込室を空気排出弁の出口側と接続したものである。 The present invention cools waste steam flowing down from a steam device with a heat exchanger to condense the steam, and an air discharge valve is attached to the upper part of the heat exchanger, and an electric pump and a lower part of the heat exchanger. The liquid ejectors are sequentially connected, and the suction chamber of the liquid ejector is connected to the outlet side of the air discharge valve.
本発明の廃蒸気回収装置は、熱交換器から空気排出弁で混入空気を系外へ排出した後の温水を電動ポンプが吸引することで、ポンプが混入空気を吸引することがないために、ポンプ能力が低下することを防止することができる。 In the waste steam recovery apparatus of the present invention, the electric pump sucks the hot water after the mixed air is discharged from the heat exchanger with the air discharge valve, so that the pump does not suck the mixed air. It is possible to prevent the pump capacity from being lowered.
図１に示すように、廃蒸気通路１と、この廃蒸気通路１に接続した熱交換器２と、熱交換器２の上部に取り付けた空気排出弁３、及び、熱交換器２の下部に接続した電動ポンプ１３と液体エゼクタ５とで廃蒸気回収装置を構成する。 As shown in FIG. 1, a waste steam passage 1, a heat exchanger 2 connected to the waste steam passage 1, an air discharge valve 3 attached to the upper portion of the heat exchanger 2, and a lower portion of the heat exchanger 2. The connected electric pump 13 and the liquid ejector 5 constitute a waste steam recovery device.
廃蒸気通路１の左端部を図示しない蒸気装置と接続し、右端部を熱交換器２の左側面上部と接続することで、蒸気装置で発生した空気の混入した廃蒸気が熱交換器２内へ供給されるものである。熱交換器２内には、冷却コイル４を配置すると共に、冷却コイル４の下端を冷却水供給管６と接続し、上端を冷却水排出管７と接続する。 By connecting the left end of the waste steam passage 1 to a steam device (not shown) and connecting the right end to the upper part of the left side surface of the heat exchanger 2, waste steam mixed with air generated in the steam device is contained in the heat exchanger 2. To be supplied to. In the heat exchanger 2, the cooling coil 4 is disposed, the lower end of the cooling coil 4 is connected to the cooling water supply pipe 6, and the upper end is connected to the cooling water discharge pipe 7.
熱交換器２の上面に管路８を接続して空気排出弁３を取り付ける。空気排出弁３は、弁内部の温度が所定値、例えば４０℃以下になると自動的に開弁するもので、空気排出弁３の出口側は管路９により液体エゼクタ５の吸込室１０と接続する。 The pipe 8 is connected to the upper surface of the heat exchanger 2 and the air discharge valve 3 is attached. The air discharge valve 3 is automatically opened when the temperature inside the valve becomes a predetermined value, for example, 40 ° C. or less, and the outlet side of the air discharge valve 3 is connected to the suction chamber 10 of the liquid ejector 5 by a conduit 9. To do.
熱交換器２の下端面に管路１１を接続して、電動ポンプ１３を接続する。電動ポンプ１３の吐出口側に、弁開度を調節することのできる調節弁１５と管路６を介在して液体エゼクタ５と接続する。 The pipe 11 is connected to the lower end surface of the heat exchanger 2 and the electric pump 13 is connected. The discharge port side of the electric pump 13 is connected to the liquid ejector 5 via a control valve 15 and a pipe line 6 that can adjust the valve opening.
廃蒸気通路１から熱交換器２内へ供給された空気の混入した廃蒸気は、冷却コイル４で冷却されることで、廃蒸気だけが凝縮して温水となり、一方、混入している空気は凝縮することなく、空気排出弁３を通って液体エゼクタ５の吸込室１０へと吸引される。 The waste steam mixed with the air supplied from the waste steam passage 1 into the heat exchanger 2 is cooled by the cooling coil 4 so that only the waste steam is condensed into warm water, while the mixed air is Without being condensed, it is sucked into the suction chamber 10 of the liquid ejector 5 through the air discharge valve 3.
上記のように本発明は、電動ポンプが混入空気を吸引することがないために、ポンプ能力が低下することを防止することができる。 As described above, according to the present invention, since the electric pump does not suck the mixed air, it is possible to prevent the pump capacity from being lowered.
本発明は、蒸気を使用するあらゆる蒸気使用装置に利用することができる。 The present invention can be applied to any steam using apparatus that uses steam.
