本発明は、液体に気体を多量に溶解させる際に溶解しき
れなかった気体と液体と効率よく分離する機能を有する
アキュムレータに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an accumulator that has a function of efficiently separating gas and liquid that are not completely dissolved when a large amount of gas is dissolved in a liquid.
従来にあって気液分離装置を兼ねるアキュムレータは、
流れ方向に対して水平または下り勾配をもたすことによ
り気液混合水中の気体を上方に移動しやすくし、余剰気
体の溶解を促進させ、さらにそれでも溶解しない余剰気
体を分離している。Conventional accumulators that also function as gas-liquid separators are
By providing a horizontal or downward slope with respect to the flow direction, the gas in the gas-liquid mixed water is facilitated to move upward, promoting the dissolution of excess gas, and furthermore, the excess gas that remains undissolved is separated.

位が高(なっているため、水面の変動が激しくなると圧
力変動時に水滴までも排出部4から出てい(ことになる
。However, an accumulator with a horizontal or downward slope with respect to the flow gradient as described above is not suitable for gas separation,
Although the dissolving ability is excellent, as shown in Figure 4, the proportion of the liquid portion in the gas-liquid mixed water introduction part (rear end part 5b) in the accumulator is small, and the separated excess gas remains as large bubbles. The bubbles float above the accumulator and are violently disturbed on the water surface, resulting in rapid fluctuations in the water surface. On the other hand, since the liquid level is high at the front end portion 5a of the accumulator, if the water level fluctuates rapidly, even water droplets will come out from the discharge portion 4 when the pressure fluctuates.
本発明は上記のような問題に鑑みてなされたものであり
、その目的とするところは、溶解性能及び気液分離性能
のよい、内部の水位検知による液面制御を行うことによ

るアキュムレータを提供することにある。The present invention was made in view of the above-mentioned problems, and its purpose is to provide good dissolution performance and gas-liquid separation performance, and to control the liquid level by internal water level detection, even during pressure fluctuations. It is an object of the present invention to provide an accumulator having a structure in which liquid does not come out from an exhaust part and water does not accumulate inside when the device is stopped.
本発明のアキュムレータは、配管の途中に十分大きな管

乃至より低くなるような勾配を持った補助流路を有する
ことを特徴とするものである。The accumulator of the present invention includes a large diameter section having a sufficiently large pipe diameter in the middle of the piping, the large diameter section having an upward slope in the flow direction, and a water level detection section and a water level detection section near the front end of the large diameter section in the flow direction. It is characterized by providing a riser pipe, providing an exhaust part above the riser pipe, and further having an auxiliary flow path having a slope such that the bottom of the front end is at the same height or lower than the bottom of the rear end. .
すなわち、本発明にあっては、アキュムレータの管径を
十分大きくすることにより、アキュムレータを流れ勾配
に対して水平または下り勾配をもたせたときと同様、気
液混合水中の余剰気体は十分に分離され、分離された気
体は立ち上がり管3に溜められ排気部4から排気される
。That is, in the present invention, by making the pipe diameter of the accumulator sufficiently large, the excess gas in the gas-liquid mixed water can be sufficiently separated, similar to when the accumulator is made to have a horizontal or downward slope with respect to the flow gradient. The separated gas is stored in the riser pipe 3 and exhausted from the exhaust section 4.

キュムレータ内の水位を一定に保つことが可能である。Furthermore, by making the accumulator have an upward slope with respect to the flow direction, the proportion of liquid in the rear end portion 5b of the accumulator increases, and even if the excess gas becomes large bubbles and floats up, the excess gas flows through the liquid onto the top surface of the accumulator. Since it moves quietly along the water level, it suppresses fluctuations in the water level due to turbulence of bubbles at the rear end 5b where the water level detection part 2 is located, making it easy to detect the water level, and injecting gas when the water level rises. It is possible to keep the water level in the accumulator constant by
その結果、アキュムレータ内の液面の激しい変動や水位
の上昇によって排出部から液体が出ていくことを防止す
る。As a result, liquid is prevented from flowing out from the discharge section due to severe fluctuations in the liquid level in the accumulator or rise in the water level.
また、前端底部が後端底部と等高乃至より低くなるよう
な勾配を持った補助流路をもっているので、装置停止時
においても内部に滞留水が溜らない。In addition, since the auxiliary flow path has a slope such that the front end bottom is at the same height or lower than the rear end bottom, water does not accumulate inside the device even when the device is stopped.
本発明を以下添付図面に示す実施例に基づいて詳述する
。The present invention will be described in detail below based on embodiments shown in the accompanying drawings.

チからなる水位検知部2を設けである。FIG. 1 shows an embodiment of the accumulator 5 of the present invention. This has a cylindrical shape with a sufficiently large diameter, and has an upward slope in the flow direction, and furthermore, the pipe 3 rises upward from the upper surface near the front end 5a in the flow direction. An exhaust section 4 consisting of an exhaust valve and a water level detection section 2 consisting of a float switch are provided on the upper part of the riser pipe 3.

The method is not limited to the float sinch method, and other methods such as an electrode method and a capacitance method may be used.

By connecting them, an auxiliary flow path 6 is formed, and stagnant water is prevented from accumulating in the rear end portion 5b of the accumulator.
第3図は、本発明に係るアキュムレータの使用状態の説

ムレータ5を設けた実施例が示しである。FIG. 3 is an explanatory diagram of the usage state of the accumulator according to the present invention, and in an embodiment, an accumulator 5 is provided between piping 1b and 1c of a fine bubble generator 12 attached to a tank 11 such as a bathtub. An example is illustrative.
アキュムレータ5はポンプ7と吐出口9との間に設けら
れるものであり、ポンプ7とは配管1bで、吐出口9と
は配管1cとでつながれている。The accumulator 5 is provided between the pump 7 and the discharge port 9, and is connected to the pump 7 by a pipe 1b and to the discharge port 9 by a pipe 1c.
微細気泡発生装置12は、吸水口8側から順に吸気管1
0、ポンプ7、アキュムレータ5、吐出口9が配置しで
ある。The micro bubble generator 12 is connected to the intake pipe 1 in order from the water intake port 8 side.
0, pump 7, accumulator 5, and discharge port 9 are arranged.

配管1aを通過する際に吸気管10がら空気や二酸加炭

とになる。When the pump 7 is driven, the liquid in the tank lI is sucked from the water intake port 8 by the action of the pump 7, and when this liquid passes through the pipe 1a, air and gases such as carbon dioxide and the like are generated in the intake pipe 10. is inhaled and dissolved under pressure within the pump 7.
そして、気体が溶解された液体は加圧されたままの状態

用をするものである。Then, the liquid in which the gas is dissolved is sent to the discharge port 9 through the pipe 1b while still being pressurized.
During this process, when the fluid flows through the accumulator 5, the accumulator 5 not only absorbs the pulsation of the liquid and absorbs the impact pressure, but also absorbs the gas that was not completely dissolved by the pressurization in the pump 7. In addition to promoting the dissolution of
Even so, the excess gas that remains undissolved and mixed in the liquid floats to the side of the riser tube 4 to separate the excess gas from the liquid.

共にそれでも溶解しない余剰気体が分離される。In other words, when a liquid containing gas flows inside the accumulator 5 as shown by the arrow hole in Figure 2, its inner diameter is sufficiently large so that the flow velocity is sufficiently slow, and the gas in the gas-liquid mixture water easily moves upward due to buoyancy. The dissolution of the excess gas is facilitated and the excess gas that still remains undissolved is separated.

部に滞留水が残らないことになる。Furthermore, since the accumulator 5 has an upward slope in the flow direction, the rear end 5b of the accumulator 5 is filled with liquid. Since it moves quietly along the top surface of the accumulator, the disturbance of the water surface at the front end 5a of the accumulator 5 is reduced. Therefore, the water level in the accumulator 5 can be detected by the water level detection part 2 provided at the upper part of the riser pipe 3 of the front end part 5a, and by controlling the liquid level, it is possible to prevent water droplets from coming out from the exhaust part 4. It can be prevented. On the other hand, the surplus gas separated upward is stored in the riser pipe 3 as shown by arrow B and is exhausted from the exhaust section 4. In addition, the liquid that has passed through the accumulator 5 is transferred to the piping IC.
It passes through the nozzle provided at the discharge port 9 and is discharged into the tank 11. At this time, the liquid in which the gas is dissolved changes from a pressurized state to a state in which the pressure is released all at once, so that the gas dissolved in the liquid precipitates and becomes fine bubbles that spread inside the tank 11. Then, when the microbubble generator 12 is stopped and the liquid in the tank 11 is drained, the liquid in the accumulator 6 flows downward (in the direction of the flow gradient) by gravity, and no stagnant water remains inside.

れもなくなった。In the present invention, as described above, an accumulator with a sufficient pipe diameter is provided in the middle of the piping, this is made to have an upward slope in the flow direction, and a water level detection part and a riser pipe are installed near the front end in the flow direction. Since the exhaust part is provided at the top of this riser pipe, when separating excess gas, gas and liquid can be separated with a simple configuration, and turbulence on the water surface inside the accumulator is suppressed, thereby reducing the internal water level. It has become possible to control the liquid level through detection, and as a result, it has become possible to prevent liquid from flowing out from the discharge section. Moreover, despite the uphill slope, the auxiliary flow path prevents stagnant water from accumulating in the accumulator (the liquid inside will not rot, or contaminants will clog the exhaust valve or nozzle). There is no longer any risk of damage due to freezing.
