The vane-shaped straightening plates 214 and 215 are attached to the vertical part of the liquid supply pipe 205 so that their tips fit between the straightening plates 211 and 212, and between the straightening plates 212 and 213, respectively, and a small-diameter straightening plate 216 with a jagged periphery is also provided below the third ring-shaped straightening plate 213.
これら特許文献１～３に記載の装置によれば、河川等から汲み上げた水を噴水の様に容器内で上向きに噴出させ、落下する水流を容器内壁や水供給管の外面に設置した整流板で整流することによって容器内に流下するカーテン状の水膜を形成し、気体の置換効率を高めるために上述の様な構造を採用している。 According to the devices described in Patent Documents 1 to 3, water is pumped up from a river or other source and sprayed upward inside a container like a fountain, and the falling water flow is rectified by baffles installed on the inner wall of the container or on the outer surface of the water supply pipe, forming a curtain-like water film that flows down inside the container, and the above-mentioned structure is used to increase the efficiency of gas replacement.
本発明は、さらなる気体置換効率の向上、製造コスト並びにランニングコストの低廉化を目的としてなされた。 The present invention was made with the aim of further improving gas replacement efficiency and reducing manufacturing and running costs.
上記目的を達成するためになされた本発明の気体置換装置は、容器本体と、前記容器本体の上部で液体を噴出させる液体供給管と、前記容器本体の下部から液体を排出する液体排出管と、前記容器本体内に設置された複数段の整流板と、前記容器本体内へと置換ガスを供給する置換ガス供給管と、前記容器本体から気体を排出する気体排出管とを備え、前記容器本体内を大気圧以上に維持しつつ、前記液体供給管から噴出された液体を前記整流板に沿って流下させて前記容器本体内にカーテン状の液体膜を形成し、液体中に溶存している気体を前記置換ガスと置換する装置であって、さらに、以下の構成をも備えていることを特徴とする。
（１Ａ）前記複数段の整流板は、前記容器本体の中心付近を下端とする下り傾斜となる様に設置された半円状の板材によって構成されていること。
（１Ｂ）前記複数段の整流板は、垂直方向の投影視において、前記容器本体の中心付近で下端同士がほぼ接するか若しくは重なり合う様な互い違いの配置にて設置されていること。
（２）前記液体供給管は、前記容器本体の側壁上部から、前記複数段の整流板の内の最上段の整流板の上へと液体を供給する様に、当該最上段の整流板が固定されている側の側壁に液体噴出口を開口させる様に設置されていること。
（３）前記複数段の整流板は、前記容器本体に対して挿入可能な外径を有し、前記液体供給管の噴出口と重なる開口を有する内筒の内壁面に対して半円の周縁を溶接固定され、当該内筒と共に前記容器本体に挿入して所定位置に設置する構成とされていること。
The gas replacement device of the present invention, which has been made to achieve the above-mentioned object, comprises a container body, a liquid supply pipe which sprays liquid from the upper part of the container body, a liquid discharge pipe which discharges liquid from the lower part of the container body, a multi-stage straightening plate installed within the container body, a replacement gas supply pipe which supplies a replacement gas into the container body, and a gas discharge pipe which discharges gas from the container body, and is a device which, while maintaining the inside of the container body at or above atmospheric pressure, causes the liquid sprayed from the liquid supply pipe to flow down along the straightening plate to form a curtain-like liquid film within the container body, and replaces the gas dissolved in the liquid with the replacement gas, and is further characterized by having the following configuration.
(1A) The multiple stages of straightening plates are composed of semicircular plates arranged so as to slope downward with the lower end located near the center of the container body.
(1B) The multiple stages of straightening plates are arranged in a staggered arrangement such that their lower ends are almost in contact or overlap each other near the center of the container body when viewed in a vertical projection.
(2) The liquid supply pipe is installed so as to open a liquid outlet in the side wall to which the topmost straightening plate is fixed, so as to supply liquid from the upper part of the side wall of the container body onto the topmost straightening plate of the multiple stages of straightening plates.
(3) The multi-stage straightening plate has an outer diameter that allows it to be inserted into the container body, and its semicircular periphery is welded and fixed to the inner wall surface of an inner tube having an opening that overlaps with the outlet of the liquid supply pipe, and is configured to be inserted into the container body together with the inner tube and installed in a predetermined position.
本発明の気体置換装置によれば、容器本体の上部で液体供給管から噴出された液体は、複数段の整流板の傾斜に沿って流れ、各整流板の下端から斜め下方に流れ出す。このとき、一部の液体は、各整流板の下端からカーテン状の液体膜となって容器本体の中止付近を下に向かって流れ、その他は容器本体の中心を越えて次の段の整流板の上面に届いた後、当該整流板の下端に向かって流れる。こうして、容器本体内には、複数段の整流板の下端のそれぞれからカーテン状の液体膜が流れ落ちる状態が形成される。このとき、容器本体内には大気圧以上に加圧された置換ガスが充満しており、これが液体中に溶存している気体と置換される。そして、本発明の気体置換装置によれば、容器本体内で上段の整流板から次の段の整流板、さらに次の段の整流板といった具合にジグザグ方向に液体が流れ、各整流板の下端からのカーテン状の液体膜の形成がスムーズとなり、置換ガスとの接触面積が広がり、気体置換効率を上げることができる。この結果、液体供給ポンプの小型化や運転時の液体吐出圧力の低減などが可能となって、製造コスト並びにランニングコストの低廉化を実現することができる。 According to the gas replacement device of the present invention, the liquid ejected from the liquid supply pipe at the top of the container body flows along the inclination of the multiple-stage straightening plates and flows diagonally downward from the lower end of each straightening plate. At this time, some of the liquid forms a curtain-like liquid film from the lower end of each straightening plate and flows downward near the center of the container body, while the rest flows toward the lower end of the straightening plate after reaching the upper surface of the next stage of the straightening plate beyond the center of the container body. In this way, a state in which a curtain-like liquid film flows down from each of the lower ends of the multiple stages of straightening plates is formed in the container body. At this time, the container body is filled with replacement gas pressurized to atmospheric pressure or higher, which replaces the gas dissolved in the liquid. According to the gas replacement device of the present invention, the liquid flows in a zigzag direction from the upper stage straightening plate to the next stage straightening plate and then to the next stage straightening plate in the container body, and the formation of a curtain-like liquid film from the lower end of each straightening plate becomes smooth, the contact area with the replacement gas is expanded, and the gas replacement efficiency can be improved. As a result, it is possible to miniaturize the liquid supply pump and reduce the liquid discharge pressure during operation, thereby realizing lower manufacturing and running costs.
また、本発明の気体置換装置によれば、液体を容器本体の上部側壁から流入させることができ、容器本体内に配管する必要がなくなる。これにより、容器本体を小型化させることができる。そして、容器本体内に液体供給のための配管をする必要がなくなることから、置換ガスと液体膜との接触が邪魔されることがなく、さらなる置換効率の向上を実現することができる。この結果、製造コスト並びにランニングコストのさらなる低廉化を可能にすることができる。 Furthermore, according to the gas replacement device of the present invention , the liquid can be introduced from the upper side wall of the container body, eliminating the need for piping inside the container body. This allows the container body to be made smaller. And since it is no longer necessary to install piping for supplying liquid inside the container body, the contact between the replacement gas and the liquid film is not disturbed, and replacement efficiency can be further improved. As a result, it is possible to further reduce manufacturing costs and running costs.
さらに、本発明の気体置換装置によれば、容器本体とは別体の内筒の内壁面に対して整流板を溶接固定することから、例えば、半割の筒体に各段の整流板を溶接固定した後に一体化させるといった方法で製造した内筒を用いることもでき、小型化した容器本体の内部に複数段の整流板を容易に設置することができる。なお、内筒は、液体供給管の噴出口と開口とが重なる様に容器本体に挿入され、溶接等によって容器本体に対して固定される。 Furthermore, according to the gas replacement device of the present invention , since the straightening plates are welded to the inner wall surface of the inner cylinder, which is separate from the container body, it is possible to use an inner cylinder manufactured by, for example, welding and fixing each stage of straightening plates to a half-split cylinder and then integrating them, and it is possible to easily install multiple stages of straightening plates inside the compact container body. The inner cylinder is inserted into the container body so that the nozzle and opening of the liquid supply pipe overlap, and is fixed to the container body by welding or the like.
一方、本発明の気体置換装置は、容器本体と、前記容器本体の上部で液体を噴出させる液体供給管と、前記容器本体の下部から液体を排出する液体排出管と、前記容器本体内に設置された複数段の整流板と、前記容器本体内へと置換ガスを供給する置換ガス供給管と、前記容器本体から気体を排出する気体排出管とを備え、前記容器本体内を大気圧以上に維持しつつ、前記液体供給管から噴出された液体を前記整流板に沿って流下させて前記容器本体内にカーテン状の液体膜を形成し、液体中に溶存している気体を前記置換ガスと置換する装置であって、さらに、以下の構成をも備えていることを特徴とする気体置換装置でもある。
（１Ａ）前記複数段の整流板は、前記容器本体の中心付近を下端とする下り傾斜となる様に設置された半円状の板材によって構成されていること。
（１Ｂ）前記複数段の整流板は、垂直方向の投影視において、前記容器本体の中心付近で下端同士がほぼ接するか若しくは重なり合う様な互い違いの配置にて設置されていること。
（４Ａ）前記液体供給管は、前記容器本体の中心において前記複数段の整流板の内の最上段の整流板よりも上方に至る先端の液体噴出口から上方に向かって液体を噴出させる垂直管部を備えていること。
（４Ｂ）前記複数段の整流板は、その下端に前記垂直管部を受け入れる切り欠き部が形成されていること。
（４Ｃ）前記垂直管部の上部に所定距離を離して上に凸の湾曲板を設置すると共に、当該湾曲板の中心に向かって吐出口を臨ませ、前記湾曲板の周縁から前記置換ガスを前記容器本体内へと流入させる様に、前記置換ガス供給管を設置したこと。
On the other hand, the gas replacement device of the present invention comprises a container body, a liquid supply pipe that sprays liquid from the upper part of the container body, a liquid discharge pipe that discharges liquid from the lower part of the container body, a multi-stage straightening plate installed in the container body, a replacement gas supply pipe that supplies a replacement gas into the container body, and a gas discharge pipe that discharges gas from the container body, and while maintaining the inside of the container body at or above atmospheric pressure, the liquid sprayed from the liquid supply pipe is caused to flow down along the straightening plate to form a curtain-like liquid film in the container body, and the gas dissolved in the liquid is replaced with the replacement gas, and is also a gas replacement device characterized by further comprising the following configuration.
(1A) The multiple stages of straightening plates are composed of semicircular plates arranged so as to slope downward with the lower end located near the center of the container body.
(1B) The multiple stages of straightening plates are arranged in a staggered arrangement such that their lower ends are almost in contact or overlap each other near the center of the container body when viewed in a vertical projection.
(4A) The liquid supply pipe has a vertical pipe section at the center of the container body, which has a liquid outlet at its tip that extends above the uppermost straightening plate of the multiple stages of straightening plates, and which sprays liquid upward from the liquid outlet.
(4B) The multiple stages of straightening plates have cutouts at their lower ends to receive the vertical pipe sections.
(4C) An upwardly convex curved plate is placed a predetermined distance above the vertical pipe section, and the replacement gas supply pipe is installed so that the discharge port faces toward the center of the curved plate and the replacement gas flows into the container body from the periphery of the curved plate.
かかる構成を備えた気体置換装置によれば、容器本体内に液体供給配管を施すものの、各整流板の下端の切り欠き部にて垂直部を受け入れることにより、配管が気体の置換の邪魔にならない様にすることができる。また、液体供給管から上向きに噴出される液体は、湾曲板に遮られ、湾曲板の上面側に臨まされた置換ガス排出口からの置換ガスの排出を邪魔することがなく、置換ガスは、湾曲板の上側の湾曲面に沿って全方向へ広がる様に容器本体内に充填され、容器本体内に隅々まで行き渡る様に供給される。特に、整流板の下端側の切り欠き部を液体供給配管の垂直部に外接する様に形成して整流板の下端と液体供給管の垂直部とを溶接固定すれば、整流板の振動抑制を行うことが可能となる。この様な溶接固定は、全ての段の整流板について実施する必要はなく、噴出する液体の勢いよく降り注ぐ上段側の何段かだけにしておいてもよい。振動の抑制により、容器本体内に形成される液体膜が安定するから、大型の容器を用いる場合の置換効率の向上が達成可能となり、この結果、製造コスト並びにランニングコストの低廉化を可能にすることができる。 According to the gas replacement device having such a configuration, although the liquid supply pipe is provided in the container body, the vertical portion is received in the cutout portion at the lower end of each straightening plate, so that the pipe does not interfere with the replacement of the gas. In addition, the liquid ejected upward from the liquid supply pipe is blocked by the curved plate, and does not interfere with the discharge of the replacement gas from the replacement gas outlet facing the upper surface side of the curved plate, and the replacement gas is filled in the container body so as to spread in all directions along the upper curved surface of the curved plate, and is supplied so as to reach every corner of the container body. In particular, if the cutout portion on the lower end side of the straightening plate is formed so as to circumscribe the vertical portion of the liquid supply pipe and the lower end of the straightening plate and the vertical portion of the liquid supply pipe are welded and fixed, it is possible to suppress the vibration of the straightening plate. It is not necessary to perform such welding and fixing for all the straightening plates, and it may be performed only for some of the upper stages where the ejected liquid falls vigorously. By suppressing vibration, the liquid film formed within the container body is stabilized, making it possible to improve the replacement efficiency when using a large container, thereby making it possible to reduce manufacturing costs and running costs.
本発明によれば、気体置換装置において、気体置換効率の向上、製造コスト並びにランニングコストの低廉化を実現することができる。 According to the present invention, it is possible to improve the gas replacement efficiency and reduce the manufacturing and running costs of a gas replacement device.

These four stages of straightening plates 31 to 34 are installed in a staggered arrangement so that their lower ends almost touch each other near the center of the container body 2 when projected vertically.
なお、本実施例においては、これら４段の整流板３１～３４は、容器本体２に対して挿入可能な外径を有する内筒４０の内壁面に対して半円の周縁を溶接固定され、当該内筒４０と共に容器本体２に対して着脱可能とされている。 In this embodiment, the four baffle plates 31 to 34 are fixed by welding the semicircular periphery to the inner wall surface of the inner cylinder 40, which has an outer diameter that allows it to be inserted into the container body 2, and are detachable from the container body 2 together with the inner cylinder 40.
内筒４０の上端には、リング状の接合板４１が溶接固定されている。この接合板４１は、上蓋２０の下端に溶接固定された接合板２０ａと合わされてボルト固定によって上蓋２０を容器本体２に対して固定するためのものである。 A ring-shaped joining plate 41 is welded to the upper end of the inner tube 40. This joining plate 41 is mated with a joining plate 20a that is welded to the lower end of the top lid 20, and is used to fix the top lid 20 to the container body 2 by bolting.
内筒４０には、容器本体２に取り付けられた液体供給管２ｉｎの噴出口と重なる開口４２が設けられている。この内筒４０は、液体供給管２ｉｎの噴出口と開口４２とが重なる様に容器本体２に挿入され、溶接等によって容器本体２に対して固定される。 The inner cylinder 40 has an opening 42 that overlaps with the nozzle of the liquid supply pipe 2in attached to the container body 2. The inner cylinder 40 is inserted into the container body 2 so that the nozzle of the liquid supply pipe 2in overlaps with the opening 42, and is fixed to the container body 2 by welding or the like.
実施例１の気体置換装置１によれば、容器本体２の上部で液体供給管２ｉｎから噴出された液体は、４段の整流板３１～３４の傾斜に沿って流れ、各整流板３１～３４の下端から斜め下方に流れ出す。このとき、一部の液体は、各整流板３１～３４の下端からカーテン状の液体膜となって容器本体２の中止付近を下に向かって流れ、その他は容器本体２の中心を越えて次の段の整流板３２～３４の上面に届いた後、当該整流板３２～３４の下端に向かって流れる。こうして、容器本体２内には、４段の整流板３１～３４の下端のそれぞれからカーテン状の液体膜が流れ落ちる状態が形成される。このとき、容器本体２内には大気圧以上に加圧された置換ガスが充満しており、これが液体中に溶存している気体と置換される。そして、気体置換装置１によれば、容器本体２内で上段の整流板３１から次の段の整流板３２、さらに次の段の整流板３３，…といった具合にジグザグ方向に液体が流れ、各整流板３１～３４の下端からのカーテン状の液体膜の形成がスムーズとなり、置換ガスとの接触面積が広がり、気体置換効率を上げることができる。この結果、液体供給ポンプ３の小型化や運転時の液体吐出圧力の低減などが可能となって、製造コスト並びにランニングコストの低廉化を実現することができる。 According to the gas replacement device 1 of the first embodiment, the liquid ejected from the liquid supply pipe 2in at the top of the container body 2 flows along the inclination of the four straightening plates 31-34 and flows diagonally downward from the lower end of each straightening plate 31-34. At this time, some of the liquid flows downward near the center of the container body 2 as a curtain-like liquid film from the lower end of each straightening plate 31-34, while the rest flows toward the lower end of the straightening plate 32-34 after passing the center of the container body 2 and reaching the upper surface of the straightening plate 32-34 of the next stage. In this way, a state in which a curtain-like liquid film flows down from each of the lower ends of the four straightening plates 31-34 is formed in the container body 2. At this time, the container body 2 is filled with replacement gas pressurized to atmospheric pressure or higher, which replaces the gas dissolved in the liquid. Furthermore, with the gas replacement device 1, the liquid flows in a zigzag direction within the container body 2, from the upper rectifier plate 31 to the next rectifier plate 32, the next rectifier plate 33, and so on, and the formation of a curtain-like liquid film from the lower end of each rectifier plate 31-34 becomes smooth, expanding the contact area with the replacement gas and improving the gas replacement efficiency. As a result, it becomes possible to miniaturize the liquid supply pump 3 and reduce the liquid discharge pressure during operation, thereby realizing low manufacturing and running costs.
また、本実施例の気体置換装置１では、液体供給管２ｉｎは、容器本体２の側壁上部から、４段の整流板３１～３４の内の最上段の整流板３１の上へと液体を供給する様に、当該最上段の整流板３１が固定されている側の側壁に噴出口を開口させる様に設置されている。この結果、本実施例の気体置換装置１によれば、容器本体２内に配管を敷設することなく、液体を容器本体２の上部側壁から流入させることができる。これにより、容器本体２を小型化させることができる。そして、容器本体２内に液体供給のための配管をする必要がなくなることから、置換ガスと液体膜との接触が邪魔されることがなく、さらなる置換効率の向上を実現することができる。この結果、製造コスト並びにランニングコストのさらなる低廉化を可能にすることができる。 In the gas replacement device 1 of this embodiment, the liquid supply pipe 2in is installed so that the nozzle is opened on the side wall on the side where the uppermost straightening plate 31 is fixed, so that the liquid is supplied from the upper part of the side wall of the container body 2 to the top of the uppermost straightening plate 31 of the four straightening plates 31 to 34. As a result, according to the gas replacement device 1 of this embodiment, the liquid can be made to flow in from the upper side wall of the container body 2 without laying piping inside the container body 2. This allows the container body 2 to be made smaller. And since there is no need to lay piping for liquid supply inside the container body 2, the contact between the replacement gas and the liquid film is not disturbed, and the replacement efficiency can be further improved. As a result, it is possible to further reduce the manufacturing cost and running cost.
さらに、本実施例の気体置換装置１では、４段の整流板３１～３４は、容器本体２に対して挿入可能な外径を有する内筒４０の内壁面に対して半円の周縁を溶接固定され、当該内筒４０と共に容器本体に挿入して所定位置に設置する構成を採用している。この結果、本実施例の気体置換装置１によれば、容器本体２とは別体の内筒４０の内壁面に対して整流板３１～３４を溶接固定することから、例えば、半割の筒体に各段の整流板を溶接固定した後に一体化させるといった方法で製造した内筒を用いることもでき、小型化した容器本体の内部に複数段の整流板を容易に設置することができる。 Furthermore, in the gas replacement device 1 of this embodiment, the four stages of straightening plates 31-34 are welded to the inner wall surface of the inner cylinder 40, which has an outer diameter that allows it to be inserted into the container body 2, and are inserted into the container body together with the inner cylinder 40 and installed in a predetermined position. As a result, according to the gas replacement device 1 of this embodiment, since the straightening plates 31-34 are welded to the inner wall surface of the inner cylinder 40, which is separate from the container body 2, it is possible to use an inner cylinder manufactured by, for example, welding and fixing each stage of straightening plates to a half-cylinder body and then integrating them, and it is possible to easily install multiple stages of straightening plates inside the compact container body.
実施例２の気体置換装置５１は、図４に示す様に、容器本体５２と、ポンプ５３及びモータ５４とを架台５５に設置した構成となっている。本実施例においては、容器本体５２は、フランジ５２ｆを介して架台５５に直接固定されている。 As shown in FIG. 4, the gas replacement device 51 of the second embodiment is configured such that the container body 52, the pump 53, and the motor 54 are installed on a stand 55. In this embodiment, the container body 52 is directly fixed to the stand 55 via a flange 52f.
気体置換前の液体を装置に供給する液体供給口５２ｉｎは、容器本体５２の左側面中央付近から水平に伸びる様に設けられ、ポンプ５３から伸ばされた液体供給配管５６が接続される。また、気体置換後の液体を取り出す液体排出口５２ｏｕｔは、容器本体５２の下部側壁から水平に伸びる様に設けられている。この液体排出口５２ｏｕｔには手動式の開閉バルブ５８が装備されている。 The liquid supply port 52in, which supplies the liquid before gas replacement to the device, is provided so as to extend horizontally from near the center of the left side surface of the container body 52, and is connected to a liquid supply pipe 56 extended from the pump 53. In addition, the liquid discharge port 52out, which removes the liquid after gas replacement, is provided so as to extend horizontally from the lower side wall of the container body 52. This liquid discharge port 52out is equipped with a manual opening and closing valve 58.
容器本体５２の右側面１／２よりやや上の高さにフロート装置６０が備えられている。さらに、容器本体５２の正面には、液位確認装置６１が備えられ、容器本体５２の左右側面には、操作盤６２，６３が備えられている。 A float device 60 is provided at a height slightly above 1/2 of the right side of the container body 52. In addition, a liquid level confirmation device 61 is provided on the front of the container body 52, and operation panels 62, 63 are provided on the left and right sides of the container body 52.
また、容器本体５２の天井部には、置換ガス供給管７１、気体排出管７２，７３及び液位確認用の配管７４が備えられている。本実施例においては、置換ガス供給管７１は、天井部中心に位置する様に設置されている。 The ceiling of the container body 52 is equipped with a replacement gas supply pipe 71, gas exhaust pipes 72 and 73, and a pipe 74 for checking the liquid level. In this embodiment, the replacement gas supply pipe 71 is installed so as to be located at the center of the ceiling.
容器本体５２の内部には、図５に示す様に、容器本体５２の内部にカーテン状の液体膜を形成するための４段の整流板８１～８４と、液面の揺れを安定させるための液面安定板８５が設置されている。液面安定板８５は、実施例１の液面安定板３５と同様に、４つの扇状の開口を備え、各開口の間の位置に下方に突出する様に扇形の制水板が取り付けられたものとなっている。 As shown in Figure 5, inside the container body 52, four stages of flow straightening plates 81-84 for forming a curtain-like liquid film inside the container body 52 and a liquid level stabilizing plate 85 for stabilizing the fluctuation of the liquid level are installed. The liquid level stabilizing plate 85 has four fan-shaped openings, similar to the liquid level stabilizing plate 35 in Example 1, and fan-shaped water control plates are attached so as to protrude downward between the positions between each opening.
４段の整流板８１～８４は、容器本体５２の中心付近を下端とする下り傾斜となる様に設置された半円状の板材によって構成されている。これら４段の整流板８１～８４は、垂直方向の投影視において、容器本体５２の中心付近で下端同士がほぼ接するか重なり合う様な互い違いの配置にて設置されている。 The four tiers of straightening plates 81-84 are composed of semicircular plates that are installed so as to slope downward with their lower ends near the center of the container body 52. These four tiers of straightening plates 81-84 are installed in a staggered arrangement such that their lower ends nearly touch or overlap near the center of the container body 52 when projected vertically.
本実施例においては、液体供給管５２ｉｎは、容器本体５２の中心において４段の整流板８１～８４の内の最上段の整流板８１よりも上方に至る先端の液体噴出口から上方に向かって液体を噴出させる垂直管部９１を備えている。また、４段の整流板８１～８４は、その下端に垂直管部９１を受け入れる切り欠き部８１ａ～８４ａが形成されている。そして、これら４段の整流板８１～８４は、半円の周縁を容器本体５２の内壁面に対して溶接固定されると共に、上３段については、切り欠き部８１ａ～８３ａにて垂直管部９１にも溶接固定されている。そして、本実施例においては、垂直管部９１の上部に所定距離を離して上に凸の湾曲板９２を設置すると共に、当該湾曲板９２の中心に向かって吐出口を臨ませ、湾曲板９２の周縁から置換ガスを容器本体５２内へと流入させる様に、置換ガス供給管を設７１が設置されている。 In this embodiment, the liquid supply pipe 52in is provided with a vertical pipe section 91 that ejects liquid upward from a liquid ejection port at the tip that reaches above the topmost straightening plate 81 of the four straightening plates 81 to 84 at the center of the container body 52. The four straightening plates 81 to 84 have cutouts 81a to 84a at their lower ends to receive the vertical pipe section 91. The semicircular peripheries of these four straightening plates 81 to 84 are welded to the inner wall surface of the container body 52, and the top three tiers are also welded to the vertical pipe section 91 at the cutouts 81a to 83a. In this embodiment, a curved plate 92 that is upwardly convex is installed at a predetermined distance above the vertical pipe section 91, and a replacement gas supply pipe 71 is installed so that the discharge port faces toward the center of the curved plate 92 and replacement gas flows into the container body 52 from the periphery of the curved plate 92.
実施例２の気体置換装置５１によれば、容器本体５２の上部で垂直管部９１から噴出された液体は、４段の整流板８１～８４の傾斜に沿って流れ、各整流板８１～８４の下端から斜め下方に流れ出す。このとき、一部の液体は、各整流板８１～８４の下端からカーテン状の液体膜となって容器本体５２の中止付近を下に向かって流れ、その他は容器本体５２の中心を越えて次の段の整流板８２～８４の上面に届いた後、当該整流板８２～８４の下端に向かって流れる。こうして、容器本体５２内には、４段の整流板８１～８４の下端のそれぞれからカーテン状の液体膜が流れ落ちる状態が形成される。このとき、容器本体５２内には大気圧以上に加圧された置換ガスが充満しており、これが液体中に溶存している気体と置換される。そして、気体置換装置５１によれば、容器本体５２内で上段の整流板８１から次の段の整流板８２、さらに次の段の整流板８３，…といった具合にジグザグ方向に液体が流れ、各整流板８１～８４の下端からのカーテン状の液体膜のがスムーズに形成され、置換ガスとの接触面積が広がり、気体置換効率を上げることができる。この結果、液体供給ポンプ５３の小型化や運転時の液体吐出圧力の低減などが可能となって、製造コスト並びにランニングコストの低廉化を実現することができる。 According to the gas replacement device 51 of the second embodiment, the liquid ejected from the vertical pipe section 91 at the top of the container body 52 flows along the inclination of the four straightening plates 81-84 and flows diagonally downward from the lower end of each straightening plate 81-84. At this time, some of the liquid becomes a curtain-like liquid film from the lower end of each straightening plate 81-84 and flows downward near the center of the container body 52, while the rest passes over the center of the container body 52 and reaches the upper surface of the straightening plate 82-84 of the next stage, and then flows toward the lower end of the straightening plate 82-84. In this way, a state in which a curtain-like liquid film flows down from each of the lower ends of the four straightening plates 81-84 is formed in the container body 52. At this time, the container body 52 is filled with replacement gas pressurized to atmospheric pressure or higher, which replaces the gas dissolved in the liquid. In addition, with the gas replacement device 51, liquid flows in a zigzag direction from the upper rectifier plate 81 to the next rectifier plate 82, the next rectifier plate 83, and so on within the container body 52, and a curtain-like liquid film is smoothly formed from the lower end of each rectifier plate 81-84, increasing the contact area with the replacement gas and improving the gas replacement efficiency. As a result, it is possible to reduce the size of the liquid supply pump 53 and reduce the liquid discharge pressure during operation, thereby realizing low manufacturing and running costs.
なお、本実施例の気体置換装置５１によれば、容器本体５２内における配管を必要とするものの、各整流板８１～８４の下端の切り欠き部８１ａ～８４ａにて垂直管部９１を受け入れることにより、配管が気体の置換の邪魔にならない様にすることができる。また、垂直管部９１から上向きに噴出される液体は、湾曲板９２に遮られ、湾曲板９２の上面側に臨まされた置換ガス排出口からの置換ガスの排出を邪魔することがなく、置換ガスは、湾曲板９２の上側の湾曲面に沿って全方向へ広がる様に容器本体５２内に充填され、容器本体５２内に隅々まで行き渡る様に供給される。特に、上３段の整流板８１～８３の下端側の切り欠き部８１ａ～８３ａを垂直管部９１に外接する様に形成して整流板８１～８３の下端と垂直管部９１とを溶接固定しているから、整流板８１～８３の振動抑制を行うことができる。こうした振動の抑制により、容器本体５２内に形成される液体膜が安定するから、大型の容器を用いる場合の置換効率の向上が達成可能となり、この結果、製造コスト並びにランニングコストの低廉化を可能にすることができる。 According to the gas replacement device 51 of this embodiment, although piping is required within the container body 52, the vertical pipe section 91 can be received in the cutouts 81a to 84a at the lower ends of the straightening plates 81 to 84, so that the piping does not interfere with the replacement of gas. In addition, the liquid ejected upward from the vertical pipe section 91 is blocked by the curved plate 92, and does not interfere with the discharge of the replacement gas from the replacement gas outlet facing the upper surface side of the curved plate 92, and the replacement gas is filled in the container body 52 so as to spread in all directions along the upper curved surface of the curved plate 92, and is supplied so as to reach every corner of the container body 52. In particular, the cutouts 81a to 83a on the lower end side of the upper three straightening plates 81 to 83 are formed so as to circumscribe the vertical pipe section 91, and the lower ends of the straightening plates 81 to 83 and the vertical pipe section 91 are welded and fixed, so that the vibration of the straightening plates 81 to 83 can be suppressed. By suppressing vibration in this way, the liquid film formed inside the container body 52 is stabilized, which makes it possible to improve replacement efficiency when using a large container, thereby making it possible to reduce manufacturing costs and running costs.
なお、実施例１，２において、ポンプの吐出圧は０．１Ｍｐａとし、吐出量については本装置の使用目的等に応じて３５Ｌ／ｍｉｎ～５ｔｏｎ／ｍｉｎの能力を有するものを使用する様にしている。また、置換ガス供給管２１，７１からは０．２Ｍｐａで容器本体２，５２内へと気体を送り込む様に供給圧を調整する供給圧調整機構を備えている。この結果、実施例１，２においては、気体圧は液体圧よりも０．１Ｍｐａ高い状態で容器内に進入し、容器内の液面を押し下げることとなる。 In Examples 1 and 2, the pump discharge pressure is 0.1 MPa, and the discharge rate is set to a capacity of 35 L/min to 5 tons/min depending on the purpose of use of the device. Also, a supply pressure adjustment mechanism is provided to adjust the supply pressure so that gas is sent from the replacement gas supply pipes 21 and 71 to the container body 2 and 52 at 0.2 MPa. As a result, in Examples 1 and 2, the gas pressure enters the container at 0.1 MPa higher than the liquid pressure, pushing down the liquid level in the container.
また、実施例１，２においては、液面高さは、フロートの上下動の範囲内に維持される様に、置換ガス供給量をコントロールしている。 In addition, in Examples 1 and 2, the amount of replacement gas supplied is controlled so that the liquid level is maintained within the range of the float's up and down movement.
加えて、実施例１，２においては、気体の置換が進んで容器本体２，５２内の置換ガス濃度が低下して液面が上昇したら、置換ガス供給管２１，７１を閉じ、気体排出管２２，２３，７２，７３を開くことにより、容器本体２，５２の内部の気体を排出する。 In addition, in Examples 1 and 2, when the gas replacement progresses and the replacement gas concentration in the container body 2, 52 decreases and the liquid level rises, the replacement gas supply pipe 21, 71 is closed and the gas exhaust pipes 22, 23, 72, 73 are opened to exhaust the gas from inside the container body 2, 52.
