Description

本発明は冷凍サイクルや蒸気サイクル等の液相と気相の二相流から液相を分離する気液分離器およびこれを用いた冷凍装置や蒸気サイクル等の装置を得る技術に関する。  The present invention relates to a gas-liquid separator that separates a liquid phase from a liquid phase and a gas phase two-phase flow such as a refrigeration cycle and a vapor cycle, and a technique for obtaining a device such as a refrigeration apparatus and a vapor cycle using the same.

従来の気液分離器の例には、特許文献１（特開２００９−１０９１０２号）がある。
このものには、特許文献１の説明にもあるように流入管３１よりチャンバ３５に取り込まれたオイルと気体冷媒の二相流を、遠心力で旋回させ、このチャンバ３５内で気体冷媒からオイルを分離し、そのオイルを貯油部に溜め、底部の送油管４０より圧縮機等に帰還させたものである。
このものは、チャンバ３５および貯油部を丸棒から機械加工で円筒管を作り、これをチャンバ３５および貯油部３７としているために材料費は勿論のこと加工費等が高くなり、これを備えた冷凍装置は高価となっていた。
また、このものは流入管３１をチャンバ３５の接線方向よりチャンバ３５内に導入しているものであるが、流入管３１より上部に形成される流入管上部空間が油分離性能におよぼす影響については全く考慮していなかった。There exists patent document 1 (Unexamined-Japanese-Patent No. 2009-109102) in the example of the conventional gas-liquid separator.
In this case, as described in Patent Document 1, the two-phase flow of the oil and the gas refrigerant taken into the chamber 35 from the inflow pipe 31 is swirled by centrifugal force, and the oil is converted from the gas refrigerant to the oil in the chamber 35. The oil is stored in the oil storage part and returned to the compressor or the like through the oil feed pipe 40 at the bottom.
In this, a cylindrical tube is made by machining the chamber 35 and the oil storage part from a round bar, and this is used as the chamber 35 and the oil storage part 37. Therefore, the material cost as well as the processing cost are increased, and this is provided. The refrigeration equipment was expensive.
Further, in this case, the inflow pipe 31 is introduced into the chamber 35 from the tangential direction of the chamber 35. Regarding the influence of the upper space of the inflow pipe formed above the inflow pipe 31 on the oil separation performance. I did not consider it at all.

特許文献２（特許２０１１−２４７５７５号）の気液分離器は、容器１の上部に入口管２と気相出口管３を設け、入口管から流入した二相流を遠心力により液相と気相に分離しているが、入口管２の上部空間が気液分離性能におよぼす影響については全く考慮していなかった。  In the gas-liquid separator of Patent Document 2 (Patent No. 2011-247575), an inlet pipe 2 and a gas-phase outlet pipe 3 are provided at the upper part of the container 1, and the two-phase flow flowing from the inlet pipe is separated from the liquid phase and the gas by centrifugal force. Although they are separated into phases, no consideration was given to the influence of the upper space of the inlet pipe 2 on the gas-liquid separation performance.

特開２００９−１０９１０２号  JP 2009-109102 A 特開２０１１−２４７５７５号  JP2011-247575A

特許文献１に示された油分離器は旋回部、貯油室それぞれを機械加工しているので、量産性が悪く、高価になる等の課題があった。
また、流入管より上部に形成される流入管上部空間が油分離性能におよぼす影響を明らかにすることが課題であった。Since the oil separator shown in Patent Document 1 is machined in each of the swivel unit and the oil storage chamber, there are problems such as poor mass productivity and high cost.
Another problem is to clarify the influence of the upper space of the inflow pipe formed above the inflow pipe on the oil separation performance.

特許文献２の図１に示されるように従来の遠心力式の油分離器では、流入管の流入口と吐出管の吸込口の位置関係は、流入管の流入口と吐出管の吸込口までの距離が確保され、且つ、吐出管の吸込口は流入管よりも低い位置に構成されるのが一般的である。
また、絞り等により加工した油分離器では、特許文献２の図１に示されるように流入管の上端面の上部に必然的に流入管上部空間が形成され、その空間が油分離性能低下におよぼす影響は考慮されていなかった。As shown in FIG. 1 of Patent Document 2, in the conventional centrifugal force type oil separator, the positional relationship between the inlet of the inlet pipe and the inlet of the outlet pipe is from the inlet of the inlet pipe to the inlet of the outlet pipe. And the suction port of the discharge pipe is generally configured at a position lower than the inflow pipe.
In addition, in an oil separator processed by a throttle or the like, an inflow pipe upper space is inevitably formed in the upper part of the upper end surface of the inflow pipe, as shown in FIG. The effects were not considered.

図１から図５を用いて実施の形態１について説明する。

上記図１から図５において、１は冷凍サイクル中等に組み込まれる円筒状の油分離器であり、この油分離器１は貯油室３の上部に該貯油室３の径より小さい径に作られた分離室４を有している。１２は貯油室３の上部に設けられた斜面である。この斜面１２により貯油室３の内径と分離室４の内径は連接されている。この油分離器１の外郭体２は絞り加工、鍛造加工、若しくはプレス加工等により貯油室３と分離室４が−体で構成されている。分離室４は立ち上がり壁４ａと下向きベルマウス形状の天井壁４ｂにより構成されている。そして、上端縮径部６は下向きベルマウス形状の天井壁４ｂに連接して形成されている。さらに上端縮径部６に吐出管８が接続されている。さらに、分離室４は油と気体冷媒の二相流を分離室４の接線方向より分離室４内に取り込む流入管９を有している。この流入管９は油分離器１の上部に位置している。The first embodiment will be described with reference to FIGS.
1 is a cross-sectional view showing an oil separator according to a first embodiment including the present invention, FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, and FIG. 3 is a schematic diagram of the oil separator including the present invention. FIG. 4 is an explanatory view of a main part of an oil separator provided with the present invention, and FIG. 5 is an enlarged view of a Q part in FIG.
In FIG. 1 to FIG. 5, reference numeral 1 denotes a cylindrical oil separator that is incorporated in a refrigeration cycle or the like. The oil separator 1 is formed in the upper part of the oil storage chamber 3 to have a diameter smaller than the diameter of the oil storage chamber 3. A separation chamber 4 is provided. Reference numeral 12 denotes a slope provided at the upper portion of the oil storage chamber 3. The slope 12 connects the inner diameter of the oil storage chamber 3 and the inner diameter of the separation chamber 4 together. The outer body 2 of the oil separator 1 is composed of an oil storage chamber 3 and a separation chamber 4 which are formed by drawing, forging, pressing or the like. The separation chamber 4 includes a rising wall 4a and a downward bellmouth shaped ceiling wall 4b. The upper diameter reduced portion 6 is formed so as to be connected to the downward bellmouth-shaped ceiling wall 4b. Further, a discharge pipe 8 is connected to the upper diameter reduced diameter portion 6. Further, the separation chamber 4 has an inflow pipe 9 for taking the two-phase flow of oil and gas refrigerant into the separation chamber 4 from the tangential direction of the separation chamber 4. The inflow pipe 9 is located in the upper part of the oil separator 1.

上記流入管９は図２にも示す如く分離室４の接線方向より分離室４内に導入されている。また、この流入管９は先端部に該管の吐出管８に対向する側の一部を該管中心側に向う方向に潰した傾斜部９ａを有している。流入管９は、この傾斜部９ａにより分離室４の略軸芯に導入されている吐出管８を通り越し、分離室４を構成する立ち上がり壁内面４ｃに接近するように配設されているとともに、吐出管８に当らないように構成されている。そして、流入管９より流入する油滴３０と気体冷媒の二相流を分離室４の立ち上がり壁４ａに勢い良く当て、該油滴３０と気体冷媒の二相流を旋回させ遠心力で油の分離が効率良く行なわれるよう構成されている。
なお、上記吐出管８の吐出管吸込口８ａは、分離室４の底部に設けられた平板状バッフル板１３ａ近くにまで至っている。As shown in FIG. 2, the inflow pipe 9 is introduced into the separation chamber 4 from the tangential direction of the separation chamber 4. In addition, the inflow pipe 9 has an inclined part 9a at the distal end portion, which is a part of the pipe facing the discharge pipe 8 in a direction toward the pipe center side. The inflow pipe 9 is disposed so as to pass through the discharge pipe 8 introduced into the substantially axial center of the separation chamber 4 by the inclined portion 9a and to approach the rising wall inner surface 4c constituting the separation chamber 4, It is configured not to hit the discharge pipe 8. Then, the two-phase flow of the oil droplet 30 and the gas refrigerant flowing in from the inflow pipe 9 is vigorously applied to the rising wall 4a of the separation chamber 4, and the two-phase flow of the oil droplet 30 and the gas refrigerant is swirled to cause the oil to flow by centrifugal force. The separation is performed efficiently.
The discharge pipe suction port 8a of the discharge pipe 8 reaches the vicinity of the flat baffle plate 13a provided at the bottom of the separation chamber 4.

平板状バッフル板１３ａは、立ち上がり壁４ａに係止されている。さらにＡ外郭体２ａにはビード１１が設けられている。さらにＡ外郭体２ａの下端には貯油室３の底部を覆うＡ蓋体１４ａと下端縮径部５を形成するＢ外郭体２ｂが溶接され、Ｂ外郭体２ｂの下端縮径部５には送油管７が接続されている。なお、Ａ蓋体１４ａ絞り加工または鍛造加工またはプレス加工されたものである。  The flat baffle plate 13a is locked to the rising wall 4a. Further, a bead 11 is provided on the outer shell 2a. Further, an A lid 14a covering the bottom of the oil storage chamber 3 and a B outer body 2b forming a lower end reduced diameter portion 5 are welded to the lower end of the A outer body 2a, and the lower end reduced diameter portion 5 of the B outer body 2b is fed to the lower end reduced diameter portion 5. An oil pipe 7 is connected. The A lid 14a has been drawn, forged, or pressed.

以上の構成において、分離室４内における油分離の作用について以下に説明する。
分離室４内における油分離を促す作用は、図３に示した油分離器１において、流入管９から分離室４に流入する油と気体冷媒の二相流の大部分は、分離室４の立ち上がり壁内面４ｃに沿ってＡ旋回流３７ａのように旋回しながら流入管９の下方に流れる。その間、気体冷媒に比べて比重の大きな油滴３０は、Ａ旋回流３７ａにより発生する遠心力により分離室４の立ち上がり壁内面４ｃに沿い下向油膜３１となり旋回しながら下方の貯油室３に流れる。一方、油分離を妨げる作用としては、図３に示した油分離器１において、油を分離した気体冷媒は分離室４内を旋回しながらＡ旋回流３７ａとなり、吐出管８の下方に至り吐出管吸込口８ａから吸い込まれる。なお、この種の油分離器では、その使用条件によっては微細な油滴３０を遠心力により分離室４の立ち上がり壁内面４ｃに捕捉できない場合もあり、捕捉できなかった微細な油滴３０は吐出管吸込口８ａから気体冷媒とともに吸い込まれ、その現象が油分離性能を１００％にすることを難しくしている。In the above configuration, the operation of oil separation in the separation chamber 4 will be described below.
In the oil separator 1 shown in FIG. 3, the action of promoting oil separation in the separation chamber 4 is that most of the two-phase flow of oil and gas refrigerant flowing into the separation chamber 4 from the inflow pipe 9 is in the separation chamber 4. It flows below the inflow pipe 9 while swirling along the rising wall inner surface 4c like the A swirl flow 37a. Meanwhile, the oil droplets 30 having a larger specific gravity than the gas refrigerant become a downward oil film 31 along the rising wall inner surface 4c of the separation chamber 4 by the centrifugal force generated by the A swirl flow 37a and flow into the lower oil storage chamber 3 while swirling. . On the other hand, as an action to prevent oil separation, in the oil separator 1 shown in FIG. 3, the gas refrigerant from which the oil has been separated turns into the A swirl flow 37 a while swirling in the separation chamber 4, and reaches the lower part of the discharge pipe 8 to be discharged. It is sucked from the tube suction port 8a. In this type of oil separator, depending on the use conditions, fine oil droplets 30 may not be captured on the rising wall inner surface 4c of the separation chamber 4 by centrifugal force, and the fine oil droplets 30 that could not be captured are discharged. It is sucked together with the gaseous refrigerant from the pipe suction port 8a, and this phenomenon makes it difficult to make the oil separation performance 100%.

一方、油分離性能を低下させる要因は流入管上端部９ｂの上の流入管上部空間４ｅにもある。以下にその問題を説明する。なお、流入管上部空間４ｅは流入管上端部９ｂと流入管上端部９ｂより上部の立ち上がり壁内面４ｃと天井壁内面４ｄとで構成された空間である。図３および図４に示したように、流入管上端部９ｂの上に流入管上部空間４ｅが存在すると流入管９から分離室４に流入した二相流の一部は流入管上部空間４ｅにも流入し、その二相流は流入管上部空間４ｅでＢ旋回流３７ｂのように旋回しながら上方に流れる。ここで、気体冷媒に比べて比重の大きな油滴３０は旋回により発生する遠心力により分離室４の立ち上がり壁内面４ｃに沿い上向油膜３２となり旋回しながら上方に流れて、立ち上がり壁内面４ｃと天井壁内面４ｄを接続する半径Ｒの円弧（以下、コーナー円弧の半径Ｒと称す）と、立ち上がり壁内面４ｃとの接続点Ｑ（以下、Ｑ点と称す）に達する。このとき図５に示すように、コーナー円弧の半径Ｒと、滑らかに接続する天井壁内面円弧との接続点Ｘにおける半径Ｒの円の接線と外郭体の軸芯に垂直な平面がなす角度θ（以下、角度θと称す）が大きい場合、分離室立ち上がり壁内面４ｃに沿い旋回しながらＱ点に達した油はさらに天井壁内面４ｄに沿い流れる。その後油は、吐出管の外表面に沿う油膜３３となり、落下し吐出管吸込口８ａの下端から気体冷媒とともに吸い込まれるので、油分離性能の低下の原因となる。この油分離性能の低下を防止するためには、角度θを小さくし、Ｑ点を通り、天井壁内面４ｄ側に上がろうとする上向油膜３２の流れを分断することである。なお、Ｂ旋回流３７ｂのように旋回しながら上昇する流れが上向油膜３２である。さらに、コーナー円弧の半径Ｒ（図５に図示）を小さくすることでも可能である。  On the other hand, the factor which reduces oil separation performance is also in the inflow pipe upper space 4e above the inflow pipe upper end portion 9b. The problem will be described below. The inflow pipe upper space 4e is a space constituted by an inflow pipe upper end portion 9b, a rising wall inner surface 4c and a ceiling wall inner surface 4d above the inflow tube upper end portion 9b. As shown in FIG. 3 and FIG. 4, when the inflow pipe upper space 4e exists on the inflow pipe upper end portion 9b, a part of the two-phase flow that flows into the separation chamber 4 from the inflow pipe 9 enters the inflow pipe upper space 4e. The two-phase flow flows upward while swirling like a B swirl flow 37b in the inflow pipe upper space 4e. Here, the oil droplet 30 having a larger specific gravity than the gas refrigerant becomes an upward oil film 32 along the rising wall inner surface 4c of the separation chamber 4 due to the centrifugal force generated by swirling, and flows upward while swirling. It reaches a connection point Q (hereinafter referred to as Q point) between the arc R of radius R (hereinafter referred to as corner radius R) connecting the ceiling wall inner surface 4d and the rising wall inner surface 4c. At this time, as shown in FIG. 5, the angle θ formed by the tangent of the circle of radius R at the connection point X between the radius R of the corner arc and the ceiling wall inner surface arc smoothly connected and the plane perpendicular to the axis of the outer shell When the angle (hereinafter referred to as the angle θ) is large, the oil that has reached the point Q while turning along the separation chamber rising wall inner surface 4c further flows along the ceiling wall inner surface 4d. Thereafter, the oil becomes an oil film 33 along the outer surface of the discharge pipe, falls, and is sucked together with the gaseous refrigerant from the lower end of the discharge pipe suction port 8a, which causes a decrease in oil separation performance. In order to prevent the deterioration of the oil separation performance, the flow of the upward oil film 32 that attempts to rise to the ceiling wall inner surface 4d side through the Q point is reduced by reducing the angle θ. The upward rising oil film 32 is a flow that rises while swirling like the B swirling flow 37b. Further, it is possible to reduce the radius R (shown in FIG. 5) of the corner arc.

一方、流入管上部空間４ｅに流入した二相流の気体冷媒も流入管上部で旋回しながら上方に流れるが、流入管上部空間４ｅの天井壁内面４ｄで図３に破線で示した様に吐出管近傍に沿う下向気体流３４となる。そのとき、分離しきれずに残っている微細な油滴３０を巻き込み、吐出管吸込口８ａから気体冷媒とともにその微細な油滴３０が吸い込まれ、油分離性能の低下の原因となる。  On the other hand, the two-phase gaseous refrigerant flowing into the inflow pipe upper space 4e also flows upward while swirling in the upper part of the inflow pipe, but is discharged from the inner surface 4d of the ceiling wall of the inflow pipe upper space 4e as shown by the broken line in FIG. A downward gas flow 34 along the vicinity of the pipe is obtained. At that time, the fine oil droplets 30 that cannot be separated are entrained, and the fine oil droplets 30 are sucked together with the gaseous refrigerant from the discharge pipe suction port 8a, which causes a decrease in oil separation performance.

以上に述べた現象はいずれも流入管上部空間４ｅの油滴３０に起因しており、流入管上部空間４ｅの容積Ｖが小さい程その空間に存在する油滴３０の量も少なくなるため、流入管上部空間４ｅの容積Ｖを小さくすることにより油分離性能の低下の原因を取り除くことができる。
以上の考え方に基づき、Ｈｍ／Ｄｉと油分離性能、角度θと油分離性能、およびコーナー円弧の半径Ｒと油分離性能の関係を、それぞれ実験により明らかにした結果を図６、図７および図８に示す。All the phenomena described above are caused by the oil droplets 30 in the inflow pipe upper space 4e. The smaller the volume V of the inflow pipe upper space 4e, the smaller the amount of oil droplets 30 present in that space. By reducing the volume V of the pipe upper space 4e, the cause of the decrease in oil separation performance can be eliminated.
Based on the above concept, the relationship between Hm / Di and oil separation performance, angle θ and oil separation performance, and the radius R of the corner arc and oil separation performance are clarified through experiments, respectively. It is shown in FIG.

図６は、Ｈｍ／Ｄｉに対する油分離性能の関係を示したものである。ここで、流入管上部空間４ｅの容積Ｖを分離室水平断面積Ｓで除した値は流入管上部空間４ｅの平均高さＨｍである。したがって、Ｈｍ／Ｄｉは平均高さＨｍを分離室内径Ｄｉで除した無次元平均高さを意味する。縦軸の油分離性能は、流入管９から流入する二相流の油含有率をＯＣＲ１、吐出管８から流出する二相流の油含有率をＯＣＲ２としたとき、次式で求められる値である。

Figure 0006055673
なお、ＯＣＲとは、Ｏｉｌ Ｃｉｒｃｕｌａｔｉｏｎ Ｒａｔｉｏ の略である。
図６に示すとおり、油分離性能にはＨｍ／Ｄｉ＝０．２５に変曲点があり、Ｈｍ／Ｄｉ≦０．２５とすることで良好な油分離効果を発揮する。
なお、このときの入口流量をＧｉ、当該油分離器の許容最大流量をＧｍａｘとしたとき、Ｇｉ／Ｇｍａｘ＝０．４〜０．６の場合である。FIG. 6 shows the relationship of oil separation performance with respect to Hm / Di. Here, the value obtained by dividing the volume V of the inflow pipe upper space 4e by the separation chamber horizontal sectional area S is the average height Hm of the inflow pipe upper space 4e. Therefore, Hm / Di means a dimensionless average height obtained by dividing the average height Hm by the separation chamber diameter Di. The oil separation performance on the vertical axis is a value obtained by the following equation when the oil content of the two-phase flow flowing in from the inflow pipe 9 is OCR1 and the oil content of the two-phase flow flowing out of the discharge pipe 8 is OCR2. is there.
Figure 0006055673
OCR is an abbreviation for Oil Circulation Ratio.
As shown in FIG. 6, the oil separation performance has an inflection point at Hm / Di = 0.25, and a good oil separation effect is exhibited by setting Hm / Di ≦ 0.25.
In this case, Gi / Gmax = 0.4 to 0.6, where Gi is the inlet flow rate and Gmax is the maximum allowable flow rate of the oil separator.

図７は角度θと油分離性能との関係を示したもので、横軸が角度θ、縦軸が油分離性能である。この図より、角度２８度より大きくなると性能低下が著しくなる。したがって、角度θ≦２８度とすることで天井壁内面４ｄ側に上がろうとする油の流れが分断されるので良好な油分離効果を発揮する。
また、角度θの下限値の考え方を以下に述べる。図４において、４は分離室であり、４ａは立ち上がり壁であり、４ｂは分離室天井壁、６は上端縮径部である。
図において、天井壁４ｂの加工時、先に説明した流入管上部空間４ｅの容積Ｖを小さくするために天井壁内面４ｄを角度で０度になるよう加工すれば良い訳であるが、０度に加工すると加工時の塑性変形量が大きくなることから加工時間が長くなる。したがって、角度θを０度ではなく５度以上とすることで加工時間を短くすることができるため、下限角度を５度とし、角度θの範囲を５度≦角度θ≦２８度の範囲とした。FIG. 7 shows the relationship between the angle θ and the oil separation performance, where the horizontal axis is the angle θ and the vertical axis is the oil separation performance. From this figure, the performance degradation becomes significant when the angle is larger than 28 degrees. Therefore, by setting the angle θ ≦ 28 degrees, the flow of oil going up to the ceiling wall inner surface 4d side is divided, so that a good oil separation effect is exhibited.
The concept of the lower limit value of the angle θ will be described below. In FIG. 4, 4 is a separation chamber, 4a is a rising wall, 4b is a ceiling wall of the separation chamber, and 6 is a reduced diameter portion at the upper end.
In the figure, when processing the ceiling wall 4b, the ceiling wall inner surface 4d may be processed to have an angle of 0 degrees in order to reduce the volume V of the inflow pipe upper space 4e described above. When processing is performed, the amount of plastic deformation at the time of processing increases, so the processing time becomes longer. Therefore, since the machining time can be shortened by setting the angle θ to 5 degrees or more instead of 0 degrees, the lower limit angle is set to 5 degrees, and the range of the angle θ is set to 5 degrees ≦ angle θ ≦ 28 degrees. .

図８はコーナー円弧の半径Ｒと油分離性能との関係を示したもので、横軸がコーナー円弧の半径Ｒ、縦軸が油分離性能である。この図より、コーナー円弧の半径Ｒが２．５ｍｍより大きくなると、性能低下が著しくなる。したがって、コーナー円弧の半径Ｒ≦２．５ｍｍとすることで天井壁内面４ｄ側に上がろうとする油の流れが分断されるので良好な油分離効果を発揮する。  FIG. 8 shows the relationship between the radius R of the corner arc and the oil separation performance. The horizontal axis is the radius R of the corner arc, and the vertical axis is the oil separation performance. From this figure, when the radius R of the corner arc is larger than 2.5 mm, the performance deterioration becomes remarkable. Therefore, by setting the radius of the corner arc R ≦ 2.5 mm, the flow of the oil going to rise toward the ceiling wall inner surface 4d side is divided, so that a good oil separation effect is exhibited.

以上に述べたように角度θを小さくし、コーナー円弧の半径Ｒを小さくし、また図１に示すように天井壁内面４ｄを下向きベルマウス形状にすることにより、流入管上部空間４ｅの容積Ｖを小さくでき、良好な油分離性能が得られるとともに全体の高さ寸法を低くすることができる。  As described above, the volume V of the inflow pipe upper space 4e is reduced by reducing the angle θ, reducing the radius R of the corner arc, and making the ceiling wall inner surface 4d downward bellows as shown in FIG. Can be reduced, good oil separation performance can be obtained, and the overall height can be reduced.

さらに、天井壁内面４ｄを粗面とすることで、旋回流速を低下させ天井壁内面４ｄ側に上昇しようとする油および油と気体冷媒の二相流の上昇を抑制でき良好な油分離性能が得られる。  Furthermore, by making the ceiling wall inner surface 4d rough, it is possible to suppress the increase in the two-phase flow of oil and oil and gas refrigerant that lowers the swirling flow velocity and rises toward the ceiling wall inner surface 4d side, and has good oil separation performance. can get.

さらに図１の本実施の形態においては、貯油室３の底部を覆うＡ蓋体１４ａに油溜め部１０を備え、油分離器１が傾いても油を送油管７に導き易くしている。  Further, in the present embodiment of FIG. 1, an oil sump 10 is provided in the A lid 14 a that covers the bottom of the oil storage chamber 3, and oil is easily guided to the oil feed pipe 7 even when the oil separator 1 is inclined.

本実施の形態では外郭体２の下端部径に合わせてＡ蓋体１４ａを溶接し二分割で構成することで、Ａ外郭体２ａの加工方法として絞り加工、鍛造加工、プレス加工など選択肢が広がるとともに、内部構成の仕上がり確認が可能になり信頼性が増す。  In this embodiment, the A lid body 14a is welded in accordance with the diameter of the lower end portion of the outer body 2 to be divided into two parts, so that options such as drawing, forging, and pressing can be expanded as a processing method for the A outer body 2a. At the same time, it is possible to check the finish of the internal configuration, increasing reliability.

次に、バッフル板について説明する。
バッフル板の作用および効果は、貯油室内部での油の旋回流による巻き上げ防止や、貯油室での油の旋回抑制である。このバッフル板は、用途によって設けないで油分離器を構成する場合もある。
図１において、１３ａは平板状バッフル板であり、１３ｃはこの平板状バッフル板１３ａに設けられた油を流すための孔である。Next, the baffle plate will be described.
The action and effect of the baffle plate are prevention of winding-up due to the swirling flow of oil in the oil storage chamber and suppression of oil swirling in the oil storage chamber. The baffle plate may constitute an oil separator without being provided depending on the application.
In FIG. 1, 13a is a flat baffle plate, and 13c is a hole for flowing oil provided in the flat baffle plate 13a.

平板状バッフル板１３ａの軸方向、高さ方向の位置を精度よく係止するために、Ａ外郭体２ａの立ち上がり壁内面４ｃを切削加工する場合があるが、切削加工しても耐圧性が低下しないよう、本発明は貯油室３側肉厚（ｔ１）より厚く加工した分離室立ち上がり壁４ａの肉厚（ｔ２）を予め厚肉にして切削加工の寸法を考慮している。  In order to lock the position of the flat baffle plate 13a in the axial direction and the height direction with high accuracy, the rising wall inner surface 4c of the A outer body 2a may be cut. In the present invention, the thickness (t2) of the separation chamber rising wall 4a processed to be thicker than the oil storage chamber 3 side wall thickness (t1) is set to be thick in advance, and the dimensions of the cutting process are taken into consideration.

平板状バッフル板１３ａの固定は、立ち上がり壁４ａの外周を塑性変形させて構成することが一般的であるが、上記平板状バッフル板１３ａの固定は、立ち上がり壁４ａの外周をポンチ等を使って部分的に打ち出し、Ａ突起片１５ａを形成し固定している。この場合についても、予め立ち上がり壁４ａを厚肉化しているため耐圧性を損なうことなく平板状バッフル板１３ａの軸方向、高さ方向の位置を精度よく係止できる。また、平板状バッフル板１３ａの固定は、図１６で示すＢ突起片１５ｂのように外郭体２の外周方向に連続して形成し、固定する方法もある。  The flat baffle plate 13a is generally fixed by plastically deforming the outer periphery of the rising wall 4a. The flat plate baffle plate 13a is fixed using a punch or the like on the outer periphery of the rising wall 4a. It is partially punched to form and fix the A protrusion piece 15a. Also in this case, since the rising wall 4a is thickened in advance, the axial and height positions of the flat baffle plate 13a can be accurately locked without impairing pressure resistance. Further, the flat baffle plate 13a can be fixed by continuously forming the baffle plate 13a in the outer peripheral direction of the outer shell 2 like a B projection piece 15b shown in FIG.

In the embodiment shown in FIGS. 9 and 10, the above-described corner R can be eliminated.
That is, FIG. 9 and FIG. 10 of the third embodiment will be described with reference to FIG.
6, since Hm / Di can be further reduced as compared with the first embodiment, high oil separation performance can be obtained.
As the first means, as shown in FIG. 9, the ceiling partition plate 35 is provided on the upper portion of the rising wall 4 a, and the ceiling partition plate lower surface 35 a substantially functions as the ceiling wall of the separation chamber 4. The ceiling partition plate 35 is fixed to the discharge pipe 8. In such a configuration, the volume V of the inflow pipe upper space 4e can be reduced by reducing the distance H between the ceiling partition plate lower surface 35a and the inflow pipe upper end portion 9b as much as possible, and Hm / Di ≦ 0.25. realizable.

Except for the above-described configuration in FIG. 10, the configuration is the same as that in FIG. 1, and the operation and effect are the same.

実施の形態３Embodiment 3

図１１を用いて実施の形態３について説明する。

Ｂ蓋体１４ｂを切削加工とすることで、送油管７の位置をＢ蓋体の任意の位置に容易に変更できる。さらにＢ蓋体１４ｂの厚みを変えることにより溶接方法の選択肢を広げる構造としている。また、このＢ蓋体１４ｂには、Ｂ蓋体傾斜部２９を設け油分離器１が傾いても油を送油管７に導き易くしている。
図１１における上記構成以外は図１と同じ構成であり、その作用および効果は同じである。The third embodiment will be described with reference to FIG.

実施の形態１１Embodiment 11

図２６を用いて上記した油分離器を空気調和機等の冷凍装置に適用した例を説明する。
図２６において、冷媒が蒸発器２５で蒸発し、そこで熱を奪ってガス化し、気体冷媒が圧縮機２２で吸入圧縮される。圧縮機２２から吐出される高温および高圧の気体冷媒には、圧縮機内で必要とする潤滑、シール作用をするための油が圧縮機２２より流出される。この含まれている油が圧縮機２２以外の部品に滞留した場合、圧縮機２２の潤滑作用が失われ、場合によっては圧縮機２２が故障する可能性がある。また、熱交換するための凝縮器２３および蒸発器２５内に滞留した場合は熱交換効率が低下し、空気調和機全体の能力が低下してしまうので、圧縮機２２の下流には油分離器が設けられる。
この油分離器に上記した油分離器１を適用したものである。An example in which the oil separator described above is applied to a refrigeration apparatus such as an air conditioner will be described with reference to FIG.
In FIG. 26, the refrigerant evaporates in the evaporator 25, where it takes heat and gasifies, and the gaseous refrigerant is sucked and compressed by the compressor 22. The high-temperature and high-pressure gas refrigerant discharged from the compressor 22 flows out of the compressor 22 with oil for lubricating and sealing required in the compressor. When the contained oil stays in parts other than the compressor 22, the lubricating action of the compressor 22 is lost, and in some cases, the compressor 22 may break down. In addition, if the heat stays in the condenser 23 and the evaporator 25 for heat exchange, the heat exchange efficiency is lowered and the capacity of the entire air conditioner is lowered. Therefore, an oil separator is disposed downstream of the compressor 22. Is provided.
The oil separator 1 described above is applied to this oil separator.

圧縮機２２から流入管９を介して分離室４に入った油と気体冷媒の二相流は遠心力により旋回し油を分離する。そして、分離された気体冷媒は吐出管８から凝縮器２３側に出ていき、分離された油は貯油室３に溜る。溜った油は、圧縮機２２内に高低圧の圧力差により送油管７を通って圧縮機２２に戻り、圧縮機２２の軸受部および摺動部等を潤滑する。
油分離器１の吐出管８から出た気体冷媒は、凝縮器２３で外部と熱交換することによって液冷媒となり、膨張弁２４を通って、蒸発器２５に入る。
これを繰り返すことにより空気調和機は所定の性能を確保する。
このとき、本発明を備えた油分離器１は先に説明する作用効果を奏するものである。The two-phase flow of oil and gaseous refrigerant that has entered the separation chamber 4 from the compressor 22 via the inflow pipe 9 is swirled by centrifugal force to separate the oil. Then, the separated gas refrigerant goes out to the condenser 23 side from the discharge pipe 8, and the separated oil is accumulated in the oil storage chamber 3. The accumulated oil returns to the compressor 22 through the oil feed pipe 7 due to a high-low pressure difference in the compressor 22, and lubricates the bearing portion and the sliding portion of the compressor 22.
The gaseous refrigerant discharged from the discharge pipe 8 of the oil separator 1 becomes a liquid refrigerant by exchanging heat with the outside in the condenser 23, and enters the evaporator 25 through the expansion valve 24.
By repeating this, the air conditioner ensures a predetermined performance.
At this time, the oil separator 1 provided with the present invention has the effects described above.

実施の形態１２Embodiment 12

図２７について実施の形態１２について説明する。
以上の実施例では、油を分離する例として説明したが、この分離器は油に限らず、水のミストでも同様にミスト分離器として使用できる。
次に図２７を用いて、上記したミスト分離器を、蒸気サイクル装置に適用した例を説明する。
図２７において、給水ポンプ３８で圧縮された水は、ボイラ３９で加熱され高圧水蒸気となる。このとき、高圧水蒸気には水滴ミストが混入しており、水滴ミストがタービン４０に流入するとタービンブレードに損傷を与える。したがって、タービン４０に入る前にミスト分離器１を設け、流入管９から水滴ミストが混入した高圧水蒸気を、ミスト分離器１に導き、水滴ミストを除去した高圧水蒸気を吐出管８からタービン４０に導く。タービン４０で高圧水蒸気が膨張することにより、動力を発生し、発電機４１で発電する。膨張した低圧蒸気は復水器４２で凝縮し、水となり給水ポンプ３８に供給される。一方、ミスト分離器１で分離した水滴ミストは、送液管７より給水ポンプ３８の吸込み側に戻される。
これを繰り返すことにより蒸気サイクル装置は所定の機能を確保する。
上記の如く本発明の気液分離装置は上記サイクルに適用を拡大することもできる。Embodiment 12 will be described with reference to FIG.
In the above embodiment, the oil was separated as an example. However, this separator is not limited to oil, and water mist can be used as a mist separator.
Next, an example in which the above-described mist separator is applied to a steam cycle device will be described with reference to FIG.
In FIG. 27, the water compressed by the feed water pump 38 is heated by the boiler 39 to become high-pressure steam. At this time, water droplet mist is mixed in the high-pressure steam, and when the water droplet mist flows into the turbine 40, the turbine blade is damaged. Therefore, the mist separator 1 is provided before entering the turbine 40, the high-pressure steam mixed with the water droplet mist is introduced from the inflow pipe 9 to the mist separator 1, and the high-pressure steam from which the water droplet mist has been removed is transferred from the discharge pipe 8 to the turbine 40. Lead. The high-pressure steam expands in the turbine 40 to generate power, and the generator 41 generates power. The expanded low-pressure steam condenses in the condenser 42, becomes water, and is supplied to the feed water pump 38. On the other hand, the water droplet mist separated by the mist separator 1 is returned to the suction side of the water supply pump 38 from the liquid feeding pipe 7.
By repeating this, the steam cycle apparatus ensures a predetermined function.
As described above, the gas-liquid separator of the present invention can be extended to the above cycle.

本発明は以上説明した如き構成を有するものであるから、次の効果を有するものである。
即ち、貯油室の上部に該貯油室径と同径若しくは小さな径に作られた分離室を有する円筒状油分離器であり、且つ、上記貯油室の下端縮径部に送油管を、また分離室の上端縮径部に吐出管をそれぞれ接続し、さらに、油と気体冷媒の二相流の流入管を分離室立ち上がり壁の接線方向より導入し、遠心力を使って分離室内で油と気体冷媒の二相流を分離するようにした油分離器において、流入管上端部と流入管上端部より上部の立ち上がり壁内面と天井壁内面とで構成された空間の平均高さをＨｍ、分離室の内径をＤｉとしたとき、Ｈｍ／Ｄｉ≦０．２５とするとともに、分離室を絞り加工、鍛造加工、若しくはプレス加工で構成し、さらに分離室の立ち上がり壁と天井壁を一体若しくは別体で構成した油分離器である。
このことにより、性能を阻害する空間（＝流入管上部空間）を小さくし、効率の良い油分離ができるとともに油分離器の小形化が図れるものである。Since the present invention has the configuration described above, it has the following effects.
