Further, for example, Japanese Utility Model Laid-Open Publication No. 03-590003 (hereinafter referred to as "C" publication) discloses that "an inlet and an outlet are provided on the lower side wall of a vertical cylindrical tank, and the upper part communicates with the inside of the tank. A cylindrical partition separates the inflow chamber and the outflow chamber, and the inflow chamber has a sufficiently large capacity compared to the outflow chamber and has a substantially cylindrical cross section, and liquid flows into the inlet from the inflow port to the inflow chamber. An air separator provided with guide vanes so as to pivot on the inner wall of the chamber is disclosed. In addition, for example, Japanese Utility Model Laid-Open No. 03-59005
Japanese Patent Application Publication (hereinafter referred to as Japanese Utility Model Application Publication No. 2) discloses that a vertical cylindrical main body having a gas discharge valve at an upper portion and a liquid inflow port at a lower portion, and a bottom provided in the main body. A vertical cylindrical inner cylinder which is closed and has an upper opening and a lower portion having an outlet communicating with the lower portion of the main body at the same height as the inlet of the main body, and having an outlet communicating with the outside of the lower portion of the main body.

[0003]

However, the above-mentioned prior art has the following problems. (1) In the technique described in Japanese Patent Laid-Open Publication No. H06-27139, since the shape of the cylindrical container in which the intake pipe is provided is merely a cylindrical shape, the flow rate and the flow rate of the fluid into the cylindrical container are particularly irregular. In this case, the air column in which bubbles are collected tends to be formed eccentrically, and there is a problem that it is difficult to discharge the gas from the discharge pipe for removing bubbles. (2) In addition, in the technology described in Japanese Patent Publication No. A, since the discharge pipe for removing air bubbles and the extraction pipe are both located on the upper side of the cylindrical container, depending on the inflow amount and the flow velocity of the fluid, the liquid is discharged from the discharge pipe for removing air bubbles. Had to be discharged. (3) In the technique described in Japanese Patent Application Laid-Open Publication No. H8-27, since the portion of the cylindrical container where the fluid inlet is formed has a mere cylindrical shape, bubbles are collected particularly when the flow rate of the fluid into the cylindrical container is irregular. There is a problem that the formed shaft is easily formed eccentrically, and it is difficult to discharge the gas from the fluid outlet. (4) In the technique described in Japanese Patent Application Laid-Open Publication No. H08-27138, since the fluid outlet for the liquid is on the axis of the cylindrical container, turbulence is generated near the fluid outlet, and the liquid flows out steadily due to knocking or the like. There was a problem that it was difficult to make it. (5) According to the technique described in Japanese Patent Publication No. C, since the tank in which the inflow port is provided has a mere cylindrical shape, bubbles are formed particularly when the flow velocity of the fluid into the tank is irregular. There was a problem that the bubble axis was easily formed eccentrically, and it was difficult to discharge gas from the valve. (6) Further, the technique described in the publication No. C has a problem that the liquid flows out of the valve along with the gas depending on the inflow amount and the flow velocity of the fluid, because the liquid turns and turns toward the valve. Was. (7) In the technique described in Japanese Patent Application Laid-Open Publication No. H06-27139, since the inner cylinder is provided inside the main body, it is difficult to form a bubble axis formed by the collection of bubbles, and since the liquid moves toward the valve, the fluid There is a problem that the liquid flows out from the valve together with the gas depending on the inflow amount and flow velocity of the gas. (8) Further, the technology described in Japanese Patent Application Laid-Open Publication No. H11-150686 has a problem that the device is increased in size because the inner cylinder is provided inside the main body, and the productivity is lacking. (9) According to the technology described in Japanese Patent Application Publication No. H9, since the shape of the portion where the supply port of the apparatus main body is formed is simply cylindrical, bubbles are generated particularly when the flow rate of the fluid into the apparatus main body is irregular. There has been a problem that a bubble axis formed as a group is easily formed eccentrically, and it is difficult to discharge gas from the valve. (10) Further, in the technique described in Japanese Patent Application Laid-Open Publication No. H11-107, the liquid is easily formed in a turbulent flow in the vicinity of the liquid discharge port because the liquid discharge port is formed in a portion where the inner diameter of the apparatus body is small, and knocking is caused. Therefore, it is difficult to constantly discharge the liquid. (11) In the technique described in the above publication, since the inlet is formed in the cylindrical portion of the air bubble removing device, the air bubbles collect and form especially when the flow rate of the fluid into the device body is irregular. However, there is a problem that the bubble axis is easily formed eccentrically, and it is difficult to discharge gas from the valve.

The present invention has been made to solve the above-mentioned conventional problems, and has a gas axis formed therein without eccentricity, and is capable of gas-liquid separation even for a fluid containing fine bubbles. It is an object of the present invention to provide a vessel and a gas-liquid separation device capable of adjusting an internal pressure by adjusting an opening diameter adjustment valve and efficiently separating gas and liquid.

[0005]

Heavy water that does not have bubbles in the peripheral portion while rotating can flow into the liquid hollow portion 4a and be sent out from the liquid sending hole 4b, so that the liquid is sent to the liquid sending pipe 8 at a constant sending amount. Can be done. (8) The other end of the multiphase fluid injection pipe 6 is connected to a tank or the like in which the multiphase fluid is stored, and the multiphase fluid discharge pump 7 is driven to supply the multiphase fluid to the rectifying hollow portion 3a. it can.
