Description

気液分離器Gas-liquid separator
　本発明は、気液混合物から気体と液体を分離する気液分離器に関する。 The present invention relates to a gas-liquid separator that separates a gas and a liquid from a gas-liquid mixture.
　空気、冷媒ガス、プロセスガスなどのガスを圧縮するガス圧縮機は、圧縮機に吸入された空気やガスなどの気体に、冷却、潤滑等を目的として、冷凍機油等の潤滑油（液体）が用いられる。したがって、圧縮機から吐出された気体中には、潤滑油が混在している。 In a gas compressor that compresses gas such as air, refrigerant gas, and process gas, lubricating oil (liquid) such as refrigerating machine oil is added to gas such as air and gas sucked into the compressor for the purpose of cooling and lubrication. Used. Therefore, lubricating oil is mixed in the gas discharged from the compressor.
　このため、圧縮機から吐出された気体は、一旦気液分離器に導入されて、気液分離器内において冷凍機油を分離する必要がある。 Therefore, it is necessary that the gas discharged from the compressor is once introduced into the gas-liquid separator and the refrigerating machine oil is separated in the gas-liquid separator.
　このような気液分離器として、例えば下記の特許文献１には、筒状の本体部の中に、気液混合物を吹き込んで、気体と液体を遠心分離する気液分離器が開示されている。 As such a gas-liquid separator, for example, Patent Document 1 below discloses a gas-liquid separator in which a gas-liquid mixture is blown into a tubular main body to centrifuge a gas and a liquid. ..
　特許文献１に開示された気液分離器では、円筒状の圧力容器である気液分離器本体（本体部）に、内壁より所定間隔を介して湾曲形状の案内板を取り付けて、本体部の内壁と案内板との間に誘導路を形成している。 In the gas-liquid separator disclosed in Patent Document 1, a curved guide plate is attached to the gas-liquid separator main body (main body portion), which is a cylindrical pressure vessel, at predetermined intervals from the inner wall, and the main body portion is formed. A guide path is formed between the inner wall and the guide plate.

Therefore, the flow velocity of the gas-liquid mixture that has flowed into the main body decreases in the guide path. When the flow velocity of the gas-liquid mixture decreases, the gas-liquid mixture does not rotate sufficiently in the main body, and there is a possibility that the gas and the liquid cannot be separated favorably.
　本発明は上記の課題を解決するためになされたものであり、本体部に流入した気液混合物の流速を増大させて、好適に気液を分離することのできる気液分離器を提供することを目的とする。 The present invention has been made to solve the above problems, and to provide a gas-liquid separator capable of suitably separating gas-liquid by increasing the flow velocity of the gas-liquid mixture flowing into the main body.

The gas-liquid separator is provided in communication with the tubular main body, the introduction path into which the gas-liquid mixture is introduced, and a rectifying plate attached to the main body to rectify the gas-liquid mixture. And have. Further, the straightening vane has a narrow portion configured so that the distance from the inner wall of the main body portion gradually decreases toward the end portion from which the gas-liquid mixture flows out.
　上述の気液分離器によれば、整流板は、気液混合物が流出する端部に向けて、本体部の内壁との距離が徐々に狭くなるように構成される幅狭部を有するため、気液混合物の流速を増大させることができ、好適に気液を分離することができる。 According to the gas-liquid separator described above, the straightening vane has a narrow portion configured so that the distance from the inner wall of the main body gradually decreases toward the end where the gas-liquid mixture flows out.

　気液分離器１は、図１に示すように、筒状の本体部１０と、気液混合物が導入する導入路２０と、ガスが排気される排気流路３０と、冷凍機油が排出される油排出流路４０と、気液混合物を整流する整流板５０と、導入路２０の下方に設けられる中間板６０と、を有する。なお、以下の説明において、図３の左右方向をＸ方向、図３の上下方向をＹ方向と称する場合がある。ここで、気液分離器１はガス圧縮機に用いられ、好適には高速多気筒冷凍機に用いられ、より好適には船用高速多気筒冷凍機に用いられる。 As shown in FIG. 1, the gas-liquid separator 1 has a tubular main body 10, an introduction path 20 into which a gas-liquid mixture is introduced, an exhaust flow path 30 from which gas is exhausted, and refrigerating machine oil are discharged. It has an oil discharge flow path 40, a rectifying plate 50 for rectifying a gas-liquid mixture, and an intermediate plate 60 provided below the introduction path 20. In the following description, the left-right direction in FIG. 3 may be referred to as the X direction, and the up-down direction in FIG. 3 may be referred to as the Y direction. Here, the gas-liquid separator 1 is used in a gas compressor, preferably used in a high-speed multi-cylinder refrigerator, and more preferably used in a high-speed multi-cylinder refrigerator for ships.
　本体部１０は、上下方向に延在するように筒状に構成されている。本体部１０は、例えば鋳物によって構成されているが、特に限定されない。本体部１０の大きさは特に限定されないが、好適に気液を分離することのできる大きさにすることが好ましい。具体的には、気液混合物の滞留時間が０．６秒以上取れる容積にすることが好ましい。 The main body 10 is formed in a tubular shape so as to extend in the vertical direction. The main body 10 is made of, for example, a casting, but is not particularly limited. The size of the main body 10 is not particularly limited, but it is preferably set to a size capable of separating gas and liquid. Specifically, it is preferable to set the volume so that the residence time of the gas-liquid mixture can be 0.6 seconds or more.
　導入路２０は、図１、図２に示すように、本体部１０に連通して設けられる。導入路２０は、図３に示すようにＸ方向に沿って設けられる。導入路２０は、図３に示すように、本体部１０の中心に対してＹ方向に所定の距離だけオフセットして設けられる。 As shown in FIGS. 1 and 2, the introduction path 20 is provided so as to communicate with the main body 10. The introduction path 20 is provided along the X direction as shown in FIG. As shown in FIG. 3, the introduction path 20 is provided so as to be offset by a predetermined distance in the Y direction with respect to the center of the main body 10.
　排気流路３０は、図１に示すように、本体部１０の上方に設けられる。排気流路３０を介して、冷凍機油（液体）と分離されたガス（気体）が排気される。 As shown in FIG. 1, the exhaust flow path 30 is provided above the main body 10. The gas (gas) separated from the refrigerating machine oil (liquid) is exhausted through the exhaust flow path 30.
　排気流路３０は、図２に示すように、本体部１０の上端部１０Ａから一旦下方に延在するように構成されている。 As shown in FIG. 2, the exhaust flow path 30 is configured to once extend downward from the upper end portion 10A of the main body portion 10.
　例えば排気流路が、上端部から一旦下方に延在することなく、上方に延在する構成である場合であって、導入路２０および排気流路が近い場合、整流板５０の端部５０Ａから流出した気液混合物のうち、ガスから分離された冷凍機油が排気流路３０から排出される虞がある。 For example, when the exhaust flow path extends upward from the upper end portion without extending downward once, and the introduction path 20 and the exhaust flow path are close to each other, the exhaust flow path is from the end portion 50A of the straightening vane 50. Of the gas-liquid mixture that has flowed out, the refrigerating machine oil separated from the gas may be discharged from the exhaust flow path 30.
　これに対して、本実施形態に係る気液分離器１であれば、排気流路３０が、本体部１０の上端部１０Ａから一旦下方に延在するように構成されているため、整流板５０の端部５０Ａから流出した気液混合物のうち、ガスから分離された冷凍機油が排気流路３０から排出されることを好適に抑制することができる。 On the other hand, in the gas-liquid separator 1 according to the present embodiment, the exhaust flow path 30 is configured to extend downward once from the upper end portion 10A of the main body portion 10, so that the rectifying plate 50 Of the gas-liquid mixture flowing out from the end portion 50A, the refrigerating machine oil separated from the gas can be suitably suppressed from being discharged from the exhaust flow path 30.
　油排出流路４０は、図１に示すように、本体部１０の下方に設けられる。油排出流路４０を介して、ガスと分離された冷凍機油が排出される。油排出流路４０の上方には、フロート弁９０が配置されている。フロート弁９０は公知の構成であるため、詳細な説明は省略する。 As shown in FIG. 1, the oil discharge flow path 40 is provided below the main body 10. Refrigerating machine oil separated from the gas is discharged through the oil discharge flow path 40. A float valve 90 is arranged above the oil discharge flow path 40. Since the float valve 90 has a known configuration, detailed description thereof will be omitted.
　フロート弁９０が開放することによって、本体部１０の下方に貯留された冷凍機油が油排出流路４０を介して排出され、所定時間経過後に、フロート弁９０が閉鎖して、本体部１０の下方に冷凍機油が貯留される。 When the float valve 90 is opened, the refrigerating machine oil stored under the main body 10 is discharged through the oil discharge flow path 40, and after a predetermined time elapses, the float valve 90 is closed and the lower part of the main body 10 is closed. Refrigerating machine oil is stored in.
　整流板５０は、導入路２０から導入した気液混合物を整流するとともに、導入路２０から導入した気液混合物の流速を増大させる。 The rectifying plate 50 rectifies the gas-liquid mixture introduced from the introduction path 20 and increases the flow velocity of the gas-liquid mixture introduced from the introduction path 20.
　整流板５０は、図３、図４に示すように、導入路２０の上方において本体部１０の内壁に固定されるとともに、Ｘ方向のプラス側かつＹ方向のプラス側に延在する第１延在部５１と、第１延在部５１に連続して上下方向のマイナス側に延在する第２延在部５２と、を有する。整流板５０は、図４に示すように、正面視したときに、Ｌ字状に構成されている。 As shown in FIGS. 3 and 4, the straightening vane 50 is fixed to the inner wall of the main body 10 above the introduction path 20, and is a first extension extending to the plus side in the X direction and the plus side in the Y direction. It has an existing portion 51 and a second extending portion 52 that is continuous with the first extending portion 51 and extends to the minus side in the vertical direction. As shown in FIG. 4, the straightening vane 50 is formed in an L shape when viewed from the front.
　第１延在部５１が本体部１０の内壁に対して固定される方法は、特に限定されないが、例えば溶接による固定である。なお、整流板は、本体部１０の内壁と一体的に構成されていてもよい。第１延在部５１は、図３に示すように、導入路２０から導入された気液混合物が衝突するように、導入路２０を覆うように、Ｘ方向のプラス側かつＹ方向のプラス側に延在する。 The method of fixing the first extending portion 51 to the inner wall of the main body portion 10 is not particularly limited, but is fixed by welding, for example. The straightening vane may be integrally formed with the inner wall of the main body 10. As shown in FIG. 3, the first extending portion 51 covers the introduction path 20 so that the gas-liquid mixture introduced from the introduction path 20 collides with the plus side in the X direction and the plus side in the Y direction. Extends to.
　第１延在部５１は、図３、図４に示すように、上方から視たときかつ正面視したときに、直線状に構成されている。また、第２延在部５２は、図４に示すように、正面視したときに、直線状に構成されている。 As shown in FIGS. 3 and 4, the first extending portion 51 is formed in a straight line when viewed from above and when viewed from the front. Further, as shown in FIG. 4, the second extending portion 52 is formed in a straight line when viewed from the front.
　上述したように、第１延在部５１が導入路２０の上方において、本体部１０の内壁に固定されているため、第１延在部５１が邪魔板として作用して、導入路２０から導入した気液混合物のうち、冷凍機油が排気流路３０から排出されることを好適に抑制することができる。 As described above, since the first extending portion 51 is fixed to the inner wall of the main body portion 10 above the introduction path 20, the first extending portion 51 acts as an obstacle plate and is introduced from the introduction path 20. Of the resulting gas-liquid mixture, it is possible to preferably prevent the refrigerating machine oil from being discharged from the exhaust flow path 30.
　また、整流板５０の第１延在部５１は、図３に示すように、上方から視たときに、気液混合物が流出する端部５０Ａに向けて、本体部１０の内壁との距離が徐々に狭くなるように構成される幅狭部５３を有する。すなわち、幅狭部５３近傍において、第１延在部５１の端部５０Ａに向けて徐々に本体部１０の内壁に近づいている。この構成によれば、気液混合物の流速を増大させることができ、より好適に気液を分離することができる。 Further, as shown in FIG. 3, the first extending portion 51 of the straightening vane 50 has a distance from the inner wall of the main body portion 10 toward the end portion 50A from which the gas-liquid mixture flows out when viewed from above. It has a narrow portion 53 that is configured to be gradually narrowed. That is, in the vicinity of the narrow portion 53, the inner wall of the main body portion 10 is gradually approached toward the end portion 50A of the first extending portion 51. According to this configuration, the flow velocity of the gas-liquid mixture can be increased, and the gas-liquid can be separated more preferably.
　ここで、例えば、導入路２０における気液混合物の流速が４ｍ／ｓ～１０ｍ／ｓであるとき、整流板５０の端部５０Ａにおける気液混合物の流速は、６ｍ／ｓ～１５ｍ／ｓである。 Here, for example, when the flow velocity of the gas-liquid mixture in the introduction path 20 is 4 m / s to 10 m / s, the flow velocity of the gas-liquid mixture at the end portion 50A of the straightening vane 50 is 6 m / s to 15 m / s. ..
　中間板６０は、図１に示すように、導入路２０よりも下方に設けられる。中間板６０は、本体部１０の内径よりも小さい内径を備える。中間板６０はいわゆるドーナツ形状を備えている。中間板６０の内径は、特に限定されないが、本体部１０の内径の０．４～０．６倍である。 As shown in FIG. 1, the intermediate plate 60 is provided below the introduction path 20. The intermediate plate 60 has an inner diameter smaller than the inner diameter of the main body 10. The intermediate plate 60 has a so-called donut shape. The inner diameter of the intermediate plate 60 is not particularly limited, but is 0.4 to 0.6 times the inner diameter of the main body 10.
　中間板６０は、本体部１０に対して別体に構成されており、中間板６０は、例えば溶接によって、本体部１０に対して固定されている。 The intermediate plate 60 is configured separately from the main body 10, and the intermediate plate 60 is fixed to the main body 10 by welding, for example.
　中間板６０は、ＸＹ平面に沿って形成される。すなわち、中間板６０は、気液分離器１に対して傾斜することなく、略水平となるように構成される。このように中間板６０は、水平方向に沿って設けられるため、容易に製造することができる。 The intermediate plate 60 is formed along the XY plane. That is, the intermediate plate 60 is configured to be substantially horizontal with respect to the gas-liquid separator 1 without being inclined. Since the intermediate plate 60 is provided along the horizontal direction in this way, it can be easily manufactured.
　このように中間板６０が設けられることによって、中間板が設けられない構成と比較して、上下方向に沿う旋回領域Ｒ（図２参照）が狭くなり、旋回速度を向上させることができる。したがって、気液を好適に分離することができる。 By providing the intermediate plate 60 in this way, the turning region R (see FIG. 2) along the vertical direction becomes narrower and the turning speed can be improved as compared with the configuration in which the intermediate plate is not provided. Therefore, gas and liquid can be suitably separated.
　以上のように構成された気液分離器１において、気液混合物が導入路２０から導入されると、導入された気液混合物は、本体部１０の内壁および整流板５０の間を流れつつ、整流板５０の端部５０Ａから流出する。ここで、整流板５０は幅狭部５３を有するため、気液混合物の流速が増大した状態で整流板５０の端部５０Ａから流出する。整流板５０の端部５０Ａから流出した気液混合物は、本体部１０の内壁を旋回することによって、気液が遠心分離される（図３参照）。 In the gas-liquid separator 1 configured as described above, when the gas-liquid mixture is introduced from the introduction path 20, the introduced gas-liquid mixture flows between the inner wall of the main body 10 and the straightening vane 50 while flowing. It flows out from the end portion 50A of the straightening vane 50. Here, since the straightening vane 50 has a narrow portion 53, it flows out from the end portion 50A of the straightening vane 50 in a state where the flow velocity of the gas-liquid mixture is increased. The gas-liquid mixture flowing out from the end portion 50A of the straightening vane 50 is centrifuged by swirling the inner wall of the main body portion 10 (see FIG. 3).
　例えば、冷凍機油の油滴が小さい場合は、遠心分離しにくい。よって、気液混合物が本体部１０の内壁を旋回する際に、油滴を集めて大きな油滴にして、本体部１０の内壁を沿って重力沈降させることができる。 For example, if the oil droplets of the refrigerating machine oil are small, it is difficult to centrifuge. Therefore, when the gas-liquid mixture swirls around the inner wall of the main body 10, oil droplets can be collected into large oil droplets and gravitationally settled along the inner wall of the main body 10.
　以上説明したように、本実施形態に係る気液分離器１は、気液混合物から気体と液体を分離する気液分離器１である。気液分離器１は、筒状の本体部１０と、本体部１０に連通して設けられ、気液混合物が導入する導入路２０と、本体部１０に取り付けられ、気液混合物を整流する整流板５０と、を有する。また、整流板５０は、気液混合物が流出する端部５０Ａに向けて、本体部１０の内壁との距離が徐々に狭くなるように構成される幅狭部５３を有する。このように構成された気液分離器１によれば、整流板５０は、気液混合物が流出する端部５０Ａに向けて、本体部１０の内壁との距離が徐々に狭くなるように構成される幅狭部５３を有するため、気液混合物の流速を増大させて、好適に気液を分離することができる。 As described above, the gas-liquid separator 1 according to the present embodiment is a gas-liquid separator 1 that separates a gas and a liquid from a gas-liquid mixture. The gas-liquid separator 1 is provided in communication with the tubular main body 10 and the main body 10, and is attached to the introduction path 20 into which the gas-liquid mixture is introduced and the main body 10 to rectify the gas-liquid mixture. It has a plate 50 and. Further, the straightening vane 50 has a narrow portion 53 configured so that the distance from the inner wall of the main body portion 10 gradually decreases toward the end portion 50A from which the gas-liquid mixture flows out. According to the gas-liquid separator 1 configured in this way, the rectifying plate 50 is configured so that the distance from the inner wall of the main body 10 gradually decreases toward the end 50A where the gas-liquid mixture flows out. Since the narrow portion 53 is provided, the flow velocity of the gas-liquid mixture can be increased to preferably separate the gas-liquid.
　また、整流板５０は、上方から視たときに、直線状に構成されている。このように構成された気液分離器１によれば、整流板５０を容易に製造することができる。 Further, the straightening vane 50 is formed in a straight line when viewed from above. According to the gas-liquid separator 1 configured in this way, the straightening vane 50 can be easily manufactured.
　また、整流板５０は正面視した際に、導入路２０の上方において、本体部１０の内壁に固定されている。このように構成された気液分離器１によれば、整流板５０の端部５０Ａから流出した気液混合物のうち、ガスから分離された冷凍機油が排気流路３０から排出されることを好適に抑制することができる。 Further, the straightening vane 50 is fixed to the inner wall of the main body 10 above the introduction path 20 when viewed from the front. According to the gas-liquid separator 1 configured in this way, it is preferable that the refrigerating machine oil separated from the gas out of the gas-liquid mixture flowing out from the end portion 50A of the straightening vane 50 is discharged from the exhaust flow path 30. Can be suppressed.
　また、気液分離器１は、導入路２０より下方に設けられ、本体部１０の内径よりも小さい内径を備える中間板６０をさらに有する。このように構成された気液分離器１によれば、上下方向に沿う旋回領域Ｒが狭くなり、旋回速度を向上させることができ、より好適に気液を分離することができる。 Further, the gas-liquid separator 1 further has an intermediate plate 60 which is provided below the introduction path 20 and has an inner diameter smaller than the inner diameter of the main body 10. According to the gas-liquid separator 1 configured as described above, the swirling region R along the vertical direction is narrowed, the swirling speed can be improved, and the gas-liquid separator can be more preferably separated.
　また、中間板６０は、水平方向に沿って設けられる。このように構成された気液分離器１によれば、中間板６０を容易に形成することができる。 Further, the intermediate plate 60 is provided along the horizontal direction. According to the gas-liquid separator 1 configured in this way, the intermediate plate 60 can be easily formed.
　なお、本発明は上述した実施形態に限定されるものではなく、特許請求の範囲内で種々改変することができる。 The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the claims.
　例えば、上述した実施形態では、整流板５０は、図３、図４に示すように、Ｘ方向のプラス側かつＹ方向のプラス側に延在する第１延在部５１と、第１延在部５１に連続して、Ｚ方向のマイナス側に延在する第２延在部５２と、を有し、Ｌ字状に構成された。しかしながら、整流板１５０は、図５、図６に示すように、Ｘ方向のプラス側かつＹ方向のマイナス側に延在する第１延在部１５１と、第１延在部１５１に連続して、上下方向のマイナス側に延在する第２延在部１５２と、第２延在部１５２に連続して、Ｘ方向のマイナス側かつＹ方向のプラス側に延在する第３延在部１５３と、を有するＵ字状に構成されていてもよい。 For example, in the above-described embodiment, as shown in FIGS. 3 and 4, the straightening vane 50 has a first extending portion 51 extending to the plus side in the X direction and the plus side in the Y direction, and a first extending portion 51. A second extending portion 52 extending to the minus side in the Z direction is provided continuously with the portion 51, and is formed in an L shape. However, as shown in FIGS. 5 and 6, the straightening vane 150 is continuous with the first extending portion 151 extending to the plus side in the X direction and the minus side in the Y direction and the first extending portion 151. , The second extending portion 152 extending to the minus side in the vertical direction and the third extending portion 153 extending to the minus side in the X direction and the plus side in the Y direction continuously to the second extending portion 152. And may be configured in a U shape having.
　また、上述した実施形態では、導入路２０は図３に示すように、本体部１０の中心に対してＹ方向に所定の距離だけオフセットして設けられた。しかしながら、導入路２０は、図５に示すように、本体部１０の中心に対してオフセットされずに構成されていてもよい。 Further, in the above-described embodiment, as shown in FIG. 3, the introduction path 20 is provided so as to be offset by a predetermined distance in the Y direction with respect to the center of the main body 10. However, as shown in FIG. 5, the introduction path 20 may be configured without being offset with respect to the center of the main body 10.
　また、上述した実施形態では、中間板６０は水平方向に沿って設けられた。しかしながら、中間板１６０は、図７に示すように、径方向内方に向けて、下方向に傾斜するように構成されていてもよい。この構成によれば、中間板１６０上の冷凍機油を傾斜面に沿って下方に落下させることができ、中間板１６０上に冷凍機油が貯留することを好適に抑制することができる。 Further, in the above-described embodiment, the intermediate plate 60 is provided along the horizontal direction. However, as shown in FIG. 7, the intermediate plate 160 may be configured to be inclined downward in the radial direction. According to this configuration, the refrigerating machine oil on the intermediate plate 160 can be dropped downward along the inclined surface, and the accumulation of the refrigerating machine oil on the intermediate plate 160 can be preferably suppressed.
　また、上述した実施形態では、整流板５０は、上方から視たときに、直線状に構成されていたが、整流板の構成は、気液混合物が流出する端部に向けて、本体部の内壁との距離が徐々に狭くなるように構成される幅狭部を有する限りにおいて限定されず、例えば、湾曲形状に構成されていてもよい。 Further, in the above-described embodiment, the straightening vane 50 is formed in a linear shape when viewed from above, but the straightening vane is configured in the main body toward the end where the gas-liquid mixture flows out. It is not limited as long as it has a narrow portion formed so that the distance from the inner wall gradually becomes narrower, and may be formed in a curved shape, for example.
