解決しようとする問題点は、純粋蒸気使用機器での蒸気使用量が変動しても、純粋蒸気の圧力すなわち温度の変動を極力少なくすることのできる純粋蒸気発生装置を提供することである。   The problem to be solved is to provide a pure steam generator capable of minimizing fluctuations in pressure or temperature of pure steam even if the amount of steam used in the equipment using pure steam varies.

本発明は、熱交換部で純水を低圧の加熱用蒸気によって加熱することにより、不純物の少ない低圧純粋蒸気を発生するものにおいて、熱交換部に純水供給管と加熱用蒸気供給管を接続し、当該熱交換部で発生した純粋蒸気を純粋蒸気使用機器へ供給する純粋蒸気供給管を接続すると共に、当該純粋蒸気使用機器と真空ポンプを連通したことを特徴とする。   The present invention generates pure low-pressure steam with less impurities by heating pure water with low-pressure heating steam in the heat exchange section, and connects the pure water supply pipe and heating steam supply pipe to the heat exchange section. In addition, a pure steam supply pipe for supplying pure steam generated in the heat exchange section to the pure steam using equipment is connected, and the pure steam using equipment and the vacuum pump are communicated.

本発明の純粋蒸気発生装置は、純粋蒸気使用機器と真空ポンプを連通したことによって、純粋蒸気使用機器内に所定の圧力勾配が維持されて、純粋蒸気使用機器内での蒸気使用量の増減に応じて純粋蒸気使用機器内への供給蒸気量が増減することにより、純粋蒸気の圧力すなわち温度の変動を防止することができるという利点がある。   In the pure steam generator of the present invention, a predetermined pressure gradient is maintained in the pure steam using equipment by connecting the pure steam using equipment and the vacuum pump, thereby increasing or decreasing the steam usage in the pure steam using equipment. Accordingly, by increasing or decreasing the amount of steam supplied into the equipment using pure steam, there is an advantage that fluctuations in the pressure of pure steam, that is, temperature, can be prevented.

本発明は、純粋蒸気使用機器を介在して真空ポンプと熱交換部を接続したものであり、純粋蒸気使用機器での蒸気圧力すなわち蒸気温度の変動を押さえることができる。   In the present invention, a vacuum pump and a heat exchanging unit are connected via an apparatus using pure steam, and fluctuations in steam pressure, that is, steam temperature in the apparatus using pure steam can be suppressed.

図1は本発明の1実施例の構成図であって、低圧純粋蒸気を発生する熱交換部1と、純粋蒸気使用機器2、及び、真空ポンプ3で純粋蒸気発生装置を構成する。   FIG. 1 is a configuration diagram of one embodiment of the present invention, and a pure steam generator is constituted by a heat exchanging unit 1 that generates low-pressure pure steam, a pure steam using device 2, and a vacuum pump 3.

熱交換部1に純水供給管4と加熱用蒸気供給管5をそれぞれ接続する。加熱用蒸気供給管5には供給する蒸気の圧力を制御する自動制御弁6と開閉弁7を取り付ける。加熱用蒸気供給管5の出口側端部に蒸気トラップ11を取り付ける。純水供給管4は、後述する真空ポンプ3の循環水タンク8,9内を通して純水管10と接続する。純水供給管4から熱交換タンク12内へ純水が供給され、加熱用蒸気で加熱されることによって純粋蒸気を発生する。   A pure water supply pipe 4 and a heating steam supply pipe 5 are connected to the heat exchanging unit 1, respectively. An automatic control valve 6 and an on-off valve 7 for controlling the pressure of the supplied steam are attached to the heating steam supply pipe 5. A steam trap 11 is attached to the outlet side end of the heating steam supply pipe 5. The pure water supply pipe 4 is connected to the pure water pipe 10 through circulating water tanks 8 and 9 of the vacuum pump 3 described later. Pure water is supplied from the pure water supply pipe 4 into the heat exchange tank 12 and heated with heating steam to generate pure steam.

熱交換部1の上部と純粋蒸気使用機器2を純粋蒸気供給管13で接続する。供給管13には、圧力センサ14と自動制御弁15と開閉弁16及び蒸気使用機器2の入口側の圧力を検出する圧力センサ17をそれぞれ取り付ける。圧力センサ14は図示しない圧力コントローラを介して自動制御弁6と電気接続し、一方、圧力センサ17は同じくコントローラを介して自動制御弁15と電気接続する。   The upper part of the heat exchange unit 1 and the pure steam using device 2 are connected by a pure steam supply pipe 13. A pressure sensor 14, an automatic control valve 15, an on-off valve 16, and a pressure sensor 17 for detecting the pressure on the inlet side of the steam using device 2 are attached to the supply pipe 13. The pressure sensor 14 is electrically connected to the automatic control valve 6 via a pressure controller (not shown), while the pressure sensor 17 is electrically connected to the automatic control valve 15 via the controller.

純粋蒸気使用機器2内のコイル状の純粋蒸気供給管18の下端出口側は、並列に配置したバルブ19と蒸気トラップ20を介して、真空ポンプ3を構成するエゼクタ21の吸引室22と接続する。純粋蒸気使用機器2内で図示しない被加熱物を加熱して熱を奪われた供給管18内の純粋蒸気は、凝縮して復水となって、蒸気トラップ20を通って吸引室22へ吸引される。   The lower end outlet side of the coiled pure steam supply pipe 18 in the pure steam using device 2 is connected to the suction chamber 22 of the ejector 21 constituting the vacuum pump 3 through a valve 19 and a steam trap 20 arranged in parallel. . The pure steam in the supply pipe 18, which has been deprived of heat by heating an object to be heated (not shown) in the pure steam using device 2, is condensed into condensate and sucked into the suction chamber 22 through the steam trap 20. Is done.

真空ポンプ3をエゼクタ21と循環水タンク8,9と循環ポンプ23及びこれらを連結する連結管路24で構成する。エゼクタ21の出口管25を分岐して循環水タンク8,9と接続し、それぞれの循環水タンク8,9の出口側は連結管路24と接続して循環ポンプ23と連設する。真空ポンプ3は、循環ポンプ23で循環水タンク8又は9内の循環水をエゼクタ21へ供給して吸引力を発生するものである。   The vacuum pump 3 includes an ejector 21, circulating water tanks 8 and 9, a circulating pump 23, and a connecting pipe line 24 connecting them. The outlet pipe 25 of the ejector 21 is branched and connected to the circulating water tanks 8 and 9, and the outlet sides of the circulating water tanks 8 and 9 are connected to the connecting pipe 24 and connected to the circulating pump 23. The vacuum pump 3 supplies the circulating water in the circulating water tank 8 or 9 to the ejector 21 by the circulating pump 23 to generate a suction force.

純水の供給源と連通した純水管10を分岐した純水分岐管26,27を、それぞれ循環水タンク8,9内をコイル状に通過して純水供給管4と連通する。また、純水管10を分岐した分岐管28,29を循環水タンク8,9へ接続して、供給する純水の量を制御することによって、タンク8,9内の水温を任意にコントロールできるようにする。なお、タンク8,9内へ純水を供給する代わりに工業用水や水道水を供給することもできる。   The pure water branch pipes 26 and 27 branched from the pure water pipe 10 communicated with the pure water supply source pass through the circulating water tanks 8 and 9 in a coil shape and communicate with the pure water supply pipe 4. Further, by connecting the branch pipes 28 and 29 branched from the pure water pipe 10 to the circulating water tanks 8 and 9 and controlling the amount of pure water supplied, the water temperature in the tanks 8 and 9 can be arbitrarily controlled. To. In addition, industrial water or tap water can be supplied instead of supplying pure water into the tanks 8 and 9.

純水管10と純水分岐管26,27を通った純水は、循環水タンク8,9内をコイル状に通過する間にタンク8,9内の循環水によって加熱されて、純水供給管4から熱交換タンク12内へ至る。このように、熱交換タンク12へ供給する純水を加熱することによって、熱交換タンク12内での純水の蒸発を効率的に行うことができる。   The pure water that has passed through the pure water pipe 10 and the pure water branch pipes 26 and 27 is heated by the circulating water in the tanks 8 and 9 while passing through the circulating water tanks 8 and 9 in a coil shape, and the pure water supply pipe 4 to the heat exchange tank 12. Thus, by heating the pure water supplied to the heat exchange tank 12, the pure water can be efficiently evaporated in the heat exchange tank 12.

タンク8,9内の循環水の温度を、例えば、40℃と70℃と異なる温度に設定しておけば、付設のバルブを操作することによって、循環ポンプ23からエゼクタ21へ供給する循環水の水温を異なる温度へ瞬時に切り替えることができる。なお、循環水タンク8,9は通常は両方を同時に使用することはなく、付設のバルブを開閉弁していずれか一方の循環水タンク8又は9を使用する。 If the temperature of the circulating water in the tanks 8 and 9 is set to a temperature different from 40 ° C. and 70 ° C., for example, the circulating water supplied from the circulation pump 23 to the ejector 21 by operating the attached valve. The water temperature can be instantly switched to a different temperature. In general, the circulating water tanks 8 and 9 are not used at the same time, and one of the circulating water tanks 8 or 9 is used by opening and closing an attached valve.

熱交換タンク12内で発生した純粋蒸気は、純粋蒸気供給管13から蒸気使用機器2へ供給されて被加熱物を加熱し凝縮して復水となって蒸気トラップ20又はバルブ19を通ってエゼクタ21に吸引される。エゼクタ21の吸引力により、あるいは、コイル状の純粋蒸気供給管18内で蒸気が凝縮してその体積が急激に減少することにより、蒸気供給管18内の純粋蒸気は大気圧以下の真空蒸気圧力に維持される。 The pure steam generated in the heat exchange tank 12 is supplied from the pure steam supply pipe 13 to the steam using device 2 to heat and condense the object to be heated to condensate and pass through the steam trap 20 or the valve 19 and ejector. 21 is aspirated. The vapor is condensed in the coiled pure steam supply pipe 18 due to the suction force of the ejector 21, and the volume of the steam is rapidly reduced, so that the pure steam in the steam supply pipe 18 has a vacuum vapor pressure below atmospheric pressure. Maintained.

エゼクタ21で吸引することによって、蒸気供給管18内には所定の圧力勾配が維持されることにより、蒸気供給管18内での蒸気使用量の増減に応じて供給蒸気量が増減することによって、純粋蒸気の圧力すなわち温度の変動を防止することができる。 By sucking with the ejector 21, a predetermined pressure gradient is maintained in the steam supply pipe 18, and the supply steam amount increases / decreases in accordance with the increase / decrease of the steam usage amount in the steam supply pipe 18, It is possible to prevent fluctuations in the pressure or temperature of pure steam.

純粋蒸気使用機器を介在して真空ポンプと熱交換部を接続したものであり、純粋蒸気使用機器での蒸気圧力すなわち蒸気温度の変動を押さえることができる。   A vacuum pump and a heat exchanging unit are connected via a device using pure steam, and fluctuations in steam pressure, that is, steam temperature in the device using pure steam can be suppressed.
