Abstract

PURPOSE:To improve gas-liquid separation ability by arranging a large diameter part, which is arranged at a part of a piping, downward in flow direction and also arranging a vent pipe at the top of a riser arranged nearby the front end of the large diameter part. CONSTITUTION:A large diameter part 2 is arranged at a part of a piping 1 with a downward inclination in a flow direction A. A riser 3 is arranged nearby the front end of the large diameter part 2 in the flow direction A and a vent port 4 is installed at the top of this riser 3. Since an ability of gas-liquid separation is improved as a result, not only a steady exhaust can be made, but also a low cost and maintenance free production becomes possible. Moreover, putrefactions of inside liquid, cloggings of an exhaust valve and nozzle by contaminating substances and a fear of breakage due to freezing are avoided, because there is no holdup water in the accumulator while it is not operated.

[111 to be solved by the invention] However, so far, the dissolution performance and the ability to separate surplus gas and liquid and discharge only the surplus gas have been limited.
The current situation is that it has not reached the point of dramatic improvement. Furthermore, the various improvement ideas for improving efficiency and performance as described above have the problem of making the structure of the conventional accumulator more complicated, making it extremely difficult to manufacture, and increasing the cost. Furthermore, due to the complexity as described above, it was difficult to carefully monitor the exhaust valve in order to bring out its performance, and maintenance was also difficult. In addition, the cumulator according to the present invention is connected between the pump and the discharge nozzle by piping to absorb pressure fluctuations and exhaust excess gas, but even if the device is stopped, the conventional 7 cumulator does not remain in the piping. There was also the problem that the liquid would accumulate and become difficult to drain. If stagnant water accumulates in the 7-tsubo emulator like this, the stagnant water may rot and the contaminated liquid may be discharged the next time it is used, the rotten contaminants may clog the nozzle, or the stagnant water may freeze. This also caused problems such as damage to the piping. The present invention was invented in view of the above-mentioned conventional problems, and its purpose is to have good gas-liquid separation performance,
To provide an inexpensive accumulator that does not leave any stagnant water and does not require maintenance. [! A method for solving a problem PiF The Akiemulator of the present invention has a large diameter section 2 provided in a part of the pipe 1, and the large diameter section 2 has a downward slope in the flow direction. The device is characterized in that a riser pipe 3 is provided near the front end, and an exhaust section 4 is provided above the riser pipe 3.By adopting such a configuration, the above-mentioned object of the present invention can be achieved. has been achieved. [Function] That is, in the present invention, the flow of the liquid mixed with gas is slowed down when passing through the large diameter portion 2, and the gas in the gas-liquid mixed water is easily moved above the accumulator due to buoyancy. Excess gas is separated, and the separated gas is stored in the riser pipe 3 and exhausted from the exhaust section 4. In this case, by making the large diameter v62 slope downward in the flow direction,
The component of the buoyant force of the gas flows in the direction against the flow (as a result, the flow velocity of the gas becomes slower than the flow velocity of the liquid, further promoting the separation of gas and liquid. [Example] 1 The present invention will be described in detail below based on the embodiment shown in the attached drawings. Fig. 1 shows an embodiment of the 7'Jf: Emulator 5 of the present invention. Part of the piping 1 A cylindrical large-diameter portion 2 having a larger diameter than other portions of the pipe 1 is provided at the pipe 1, and the large-diameter portion 2 has a downward slope in the flow direction. A riser pipe 3 is provided vertically protruding upward from the upper surface near the front end in the flow direction, and an exhaust part 4 consisting of an exhaust valve is provided at the upper part of the riser pipe 3, so that the Achiemulator 5 according to the present invention is constructed. FIG. 4 is an explanatory diagram of the usage state of the seven-chiemulator 5 according to the present invention, and in the embodiment, the accumulator 5 is installed in a part of the piping 1 of the fine bubble generator 8 attached to a tank 12 such as a bathtub. The embodiment provided is shown.The accumulator 5 is provided between the pump 6 and the discharge lower, and the piping 1 connecting them is connected to the pump 61.
1 toward the discharge lower 11I. Here, the connection position of the pipe 1 on the entrance side of the large diameter section 2 is not limited to the one configured to connect to the top surface of the large diameter section 2 as shown in FIG. 1, but may be connected as shown in FIG. You can. The piping 1 of the micro bubble generator 8 has one end serving as a water intake port 9 and the other end serving as a discharge lower, and has a water supply port 99m.
An intake pipe 10, a pump 6, and an accumulator 5 are arranged in this order. 11 in the $4 figure is a motor for driving the pump 6. However, when the pump 6 is driven by the motor 11, the liquid in the tank 12 is sucked from the water intake port 9 by the action of the pump 6, and when this liquid passes through the pipe 1, air from the intake pipe 10 is drawn into the pipe 1. The liquid mixed with air reaches the inside of the pump 6 and is pressurized within the pump 6, and this pressurization causes the air to be dissolved in the liquid. and,
The liquid in which air has been dissolved remains in a pressurized state and is transferred to pipe 1.
During this process, the accumulator 5 absorbs the pulsation of the liquid and absorbs the impact pressure when flowing through the large diameter part 2 that constitutes the accumulator 5. In addition to this, the pressurization inside the pump 6 promotes the dissolution of the air that has not been completely dissolved, and also causes the excess air that remains undissolved and mixed in the liquid to rise to the side of the riser tube 3 and remove it from the liquid. It functions to separate excess air. That is, the liquid containing air flows inside the large diameter s2 constituting the 7-kiemulator 5 as shown in FIG.
When flowing as shown by arrow A in Figure 2, the flow rate of the liquid mixed with air slows down in the large diameter section 2, so the gas in the gas-liquid mixed water tends to move upwards in the large diameter section 2 due to buoyancy. This promotes the dissolution of excess gas and separates excess gas that does not dissolve.Furthermore, since the large diameter section 2 is sloped downward in the flow direction, as shown in Figure 3, the buoyancy of the gas The velocity component v1 of the liquid flow having a velocity V, which is parallel to the velocity W, is in the opposite direction to W, and the velocity component of the bubble is T=W-
Therefore, the gas flow rate is slower than the liquid flow rate, and the bubbles are V. Since the liquid flows in this direction, the separation between the two is facilitated. The gas thus separated upward as indicated by arrow B in FIG. 2 is stored in the riser pipe 3 and exhausted from the exhaust section 4. In FIGS. 1, 2, and 3, reference numeral 13 indicates a bubble. Here, if the riser pipe 3 is not provided at a position where gas and liquid are sufficiently separated, it is possible that some of the gas may be captured and left behind, so it is provided near the front end of the large diameter n2 in the flow direction ( The liquid in which the gas that has passed through the large diameter portion 2 is dissolved is discharged into the tank 12 from the nozzle provided on the discharge lower. When the dissolved liquid is discharged, the liquid in which the gas has been dissolved goes from a pressurized state to a state where the pressure is released all at once9.
Therefore, the gas dissolved in the liquid is precipitated, and fine bubbles are generated in the liquid in the tank 12 by the precipitated gas. Here, if the tank 12 is a bathtub and air is used as a gas and hot water is used as a liquid, the microbubbles act to wrap around the surface of the bather's body, making the perceived temperature 1 to 3 degrees Celsius higher than the actual temperature.
It has the effect of reducing the sudden rise in blood pressure when taking a bath, it also has the effect of reducing the drop in body temperature after bathing and making it difficult to cool down in the water, and the bath water is dyed white with microscopic bubbles. There will also be a visual effect. By the way, the operation of the fine bubble generator 8 is stopped and the tank 12 is
When the liquid inside the accumulator 5 is drained, the liquid inside the large diameter section 2 constituting the accumulator 5 flows downward (in the direction of the flow gradient) by gravity, so that no stagnant water remains inside the large diameter section 2. [Effect of the invention 1 In the present invention, as described above, a large diameter portion is provided in a part of the piping, the large diameter portion is sloped downward in the flow direction, and the area near the front end of the large diameter portion in the flow direction is Since a riser pipe is provided at the top of the riser pipe, and an exhaust part is provided at the top of this riser pipe, when separating excess gas in the large diameter part, gas and liquid can be separated smoothly with a simple configuration, improving gas-liquid separation performance. However, this not only makes stable exhaust possible (can be manufactured at low cost and requires no maintenance, but it also eliminates the accumulation of water in the accumulator).
There is no risk of internal liquid spoiling, contaminants clogging exhaust valves or nozzles, and no risk of damage due to freezing.
