【発明の属する技術分野】本発明は、気液混合流体より
気体を気泡の状態で分離する気泡分離装置に関するもの
で、特に、この種気液分離装置のうち、分離された気体

するものに適するようになしたものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bubble separation apparatus for separating a gas from a gas-liquid mixed fluid in the form of bubbles, and more particularly to a gas-liquid separation apparatus in which the separated gas has a bubble shape. Thus, the foam is suitable for a foam having a tendency not to collapse easily.
【０００２】従来気体混入液体より気体を分離するの
に、「図９」に示すようなサイクロン分離機が一般的に
使用されている。このサイクロン分離機は、筒状の槽１

遠心力が発生するので、重たい液体は該槽１０ａの外周
部位に、軽い気体は該槽１０ａの中心部位に気泡状とな
って集まる。そこで、上記槽１０の旋回流の中心からは
気体取出し管１５で気体を系外に取り出し、液体は下方
流出口１２より流出させるようになしてある。Conventionally, a cyclone separator as shown in FIG. 9 is generally used to separate a gas from a gas-mixed liquid. This cyclone separator has a cylindrical tank 1
The gas-mixed liquid is supplied to the inside of the tank 10a in the tangential direction from the inflow pipe 11, and a swirling flow is generated in the tank 10a. When a swirling flow is generated in the tank 10a, a centrifugal force is generated in the swirling flow, so that a heavy liquid is collected in an outer peripheral portion of the tank 10a and a light gas is collected as bubbles in a central portion of the tank 10a. Therefore, gas is taken out of the system from the center of the swirling flow of the tank 10 by a gas take-out pipe 15, and the liquid is caused to flow out from the lower outlet 12.
【０００３】なお、上記槽１０は、通常その下部に下方

この液体の一部と共に（液体のほとんどは流出口１２よ
り流出するが一部は気体取出し管１５側に流出するよう
になしてある。）気体取出し管１５ａより流出するよう
になしてある。[0003] The tank 10 is usually provided with an inverted conical portion 10b whose diameter is reduced downward at the lower portion thereof, so that the swirl flow is attenuated downstream and the swirl diameter is reduced. Inside, the whole amount is made to swirl. Further, the gas outlet pipe 15 is not simply opened at the tip thereof to the outside air, but is connected to a suction pump or the like to suck the separated gas, or the pressure of the liquid pumped from the inflow pipe 11 is applied to this liquid. (Most of the liquid flows out of the outflow port 12 but a part of the liquid flows out to the gas extraction pipe 15 side). The liquid flows out from the gas extraction pipe 15a.
【０００４】しかし、上記従来のサイクロン分離機は、
気液分離した気体が泡状となると、泡で気体取出し管１
５が詰まり、この泡が旋回流に再度捕捉されて気液分離
効率を低下する問題点を有するものであった。However, the above-mentioned conventional cyclone separator is
When the gas that has been gas-liquid separated becomes foamy, the gas extraction pipe 1
5 was clogged, and this bubble was trapped in the swirling flow again, which had the problem of reducing the gas-liquid separation efficiency.
【０００５】すなわち、従来のサイクロン分離機で発生
した泡が気体取出し管１５を塞ぐと、順次分離発生する
気体が流出しずらくなり、やがてサイクロン分離機でせ
っかく分離した気泡が液体の旋回や流れに随伴して液体
と共に下流側に流れてしまい、気液分離効率を著しく低
下することになる。[0005] That is, when the bubbles generated by the conventional cyclone separator block the gas take-out pipe 15, the gas that is sequentially generated and separated becomes difficult to flow out, and the bubbles separated by the cyclone separator eventually turn into the liquid swirl or flow. As a result, the liquid flows downstream with the liquid, and the gas-liquid separation efficiency is significantly reduced.
【０００６】そこで、上記問題点を解決する方法とし
て、サイクロン分離機に代え、解放型大型槽に気液混合
流体を長時間滞留させて自然と気体を分離排出する方法
が想定できるが、この方法は装置が大型となり、処理時
間が長いという問題点を有しておりあまり実用的で無い
とされている。Therefore, as a method for solving the above problems, a method in which a gas-liquid mixed fluid is retained for a long time in a large open tank to separate and discharge gas naturally can be supposed, instead of a cyclone separator. Has a problem that the apparatus becomes large and the processing time is long, so that it is not very practical.
【０００７】また、上記問題点の別の解決方としては、
サイクロン分離機で気泡が生じないように消泡剤を混入
する方法が想定できる。しかし、この方法は第一に消泡
剤が必要となり経費が嵩むという問題点と、さらには、
消泡剤が混入できない場合には適さないという問題点と
を有している。[0007] Another solution to the above problem is as follows.
A method of mixing an antifoaming agent so as not to generate air bubbles in the cyclone separator can be assumed. However, this method firstly requires an antifoaming agent and increases the cost, and furthermore,
There is a problem that it is not suitable when an antifoaming agent cannot be mixed.
【０００８】さらにまた別の上記問題点の解決方として

引や押し出しに余分な動力を必要とする問題点を有し、
さらには気泡と共に比較的多量な液体が流出し、この液
体の処理が後に問題となるものであった。Further, as another method of solving the above-mentioned problem, the air bubbles may be positively sucked out from the gas extracting pipe 15 or the air bubbles may be pushed out. And the inlet pipe 1
A method in which air bubbles are pushed out from the gas extraction pipe 15a together with a part of the liquid by the pressure of the liquid to be pumped from 1 can be assumed. However, this method has a problem that the device becomes complicated and operation management is complicated, and further, there is a problem that extra power is required for suctioning and pushing out bubbles,
Furthermore, a relatively large amount of liquid flows out together with the air bubbles, and the treatment of this liquid becomes a problem later.

体と粉塵を捕らえた気泡のみが分離排出されるようにす
ることが効率的であるが、ドレーン水が多量に混入する
とこの排水の水処理が必要で煩雑となるものである。For example, gas-phase ozone or air is mixed into drain water containing dust in a wet dust collector (a foaming foaming agent may be mixed in order to improve efficiency) to separate dust with air bubbles. In this case, if a large amount of drain water is drained together with the bubbles, the subsequent wastewater treatment containing dust becomes a problem, and only the gas used to generate the bubbles and the bubbles that capture the dust are separated and discharged as much as possible. It is efficient to do so, but if a large amount of drain water is mixed in, it is necessary to treat this waste water, and it becomes complicated.

The inflow pipe 11 to be generated is connected, and the lower part of the
And an inner bottom plate 16 communicating vertically below at the eccentric position.
A liquid outlet 12 is provided below 6, and either one or both of the liquid outlet 12 and the inflow pipe 11 flows into and out of the liquid outlet 12 from the inflow pipe 11. A flow control means 13 is provided to control the outflow amount of the liquid so as to maintain the liquid level L at a predetermined height. The tank 10 is housed, and the tank 10 is provided with a bubble discharge port 15 at a position above the liquid level L.
【００１３】それ故、本発明解放型気泡分離装置は、槽
１０内で旋回流が発生し遠心力で軽い気体は槽１０の中
心部に、気体が抜けた無気泡の重たい液体が槽１０の外
周部に集まるのは従来と同じ作用である。Therefore, in the open type bubble separation apparatus of the present invention, a swirling flow is generated in the tank 10, the gas which is light due to the centrifugal force is placed in the center of the tank 10, The action at the outer periphery is the same as in the conventional case.
【００１４】なお、旋回流が発生するのは同じである
が、その旋回流には多少従来と異なるところがある。す
なわち、従来は槽１０内の液体全量が常に旋回流となる
よう設定されているが、本発明の場合は、槽１０内の上
部では旋回流を阻止し、下部の外周部では旋回流が自然
と減衰するのを許容している。Although the swirl flow is the same, the swirl flow has some differences from the conventional one. That is, in the related art, the total amount of liquid in the tank 10 is set to always be a swirling flow. However, in the case of the present invention, the swirling flow is blocked in the upper part of the tank 10 and the swirling flow is naturally generated in the lower outer peripheral part. And it is allowed to attenuate.

にくい中心部位の谷部に集まる作用を呈する。That is, when a swirling flow is generated in the tank 10, as shown in FIGS. 8 and 9, the liquid surface tends to rise on the outer peripheral side due to the centrifugal force. P
A force in the direction indicated by 1 is applied. The force in the directions of the arrows P1 and P1 is a part of the swirling flow, and the force of the flow flowing from the inflow pipe 11 is added to this force, and the bulge on the outer peripheral side is further increased. Then, the bubbles have a function of gathering at the valley of the central portion where the outer peripheral side is raised and is difficult to take out.

Ｐ１，Ｐ１の力は外周側を盛り上げるよう作用するより
は旋回流に合成されるよう作用する。However, in the apparatus of the present invention, the swirling flow has an effect of suppressing the swirling flow at the upper portion by the swirling flow prevention plate 14, and the tendency of the outer peripheral portion to rise due to centrifugal force is reduced, so that the liquid level L is substantially horizontal. The effect is as follows. Note that the forces of the arrows P1 and P1 in FIG. 8 act so as to be combined with the swirling flow rather than act to raise the outer peripheral side.
【００１７】また、旋回流は流入配管１１より遠い槽１

呈する。The swirling flow is applied to the tank 1 farther from the inflow pipe 11.
It attenuates below 0. When the swirling flow is attenuated, its diameter is gradually reduced. Conventionally, the diameter of the tank 10 is reduced in accordance with the diameter of the swirling flow. However, in the present invention, since the lower part of the tank 10 is not reduced, a swirling flow is generated at the center of the lower part of the tank 10. In addition, the outer peripheral portion is not affected by the swirling flow. Unless affected by the swirling flow, gas-liquid separation cannot be expected, but if gas-liquid separation is completed at this location, an action that can ensure an atmosphere without gas-liquid mixing by stirring is exhibited. .

０内の下部外周部位では旋回流がほとんどなく、気液分
離された液体のみが集まるのでこの部位よりり順次排水
すれば、気液分離されて気泡を含まない液体のみを容易
に排水できる作用を呈するものである。Therefore, if the swirling flow is suppressed in the upper part of the tank 10 and the liquid surface is horizontal, the bubbles generated sequentially can easily overflow the upper opening edge or the like (there is no need to pump up or push out). It has the effect of being separable. In addition, tank 1
Since there is almost no swirling flow at the lower outer peripheral portion in 0 and only the liquid separated by gas and liquid collects, if the liquid is drained sequentially from this portion, only the liquid separated by gas and liquid and containing no air bubbles can be easily drained. To present.
【００１９】また、槽１０の上部で旋回流が抑止される
ことは、気液分離した気体または大気を旋回流で巻き込

を呈する。In addition, the suppression of the swirling flow in the upper part of the tank 10 has an effect that the gas or liquid separated from the gas or the atmosphere is not entrained by the swirling flow, so that the air bubbles can be efficiently removed.

たが、本発明はこれらの動力を必須とするものではない
ためである。Further, the present invention has an effect that the pressure loss is reduced as compared with the conventional cyclone separator. The reason that this pressure loss is small, in other words, the reason that the required power is small, is that the conventional cyclone separator not only generates the swirling flow, but also for the purpose of pumping the liquid to the downstream side, Although power for the purpose of removal was required, the present invention does not require these powers.

In the figure, reference numeral 10 denotes a tank which is a main part of the apparatus of the present invention. The tank 10 is formed in a cylindrical shape, and is connected to an inflow pipe 11 for causing a bubble-containing liquid to flow in a tangential direction in the tank 10 to generate a swirling flow in the tank 10 on a peripheral surface thereof.

A pump or the like (not shown) is connected to the upstream side of the inflow pipe 11 so that a bubble-containing liquid is ejected from the inflow pipe 11 into the tank 10 at a predetermined pressure.

Either the liquid outlet 12 or the inflow pipe 11 or both of them is connected to the flow rate of the liquid flowing from the inflow pipe 11 and the liquid flow. There is provided a flow rate adjusting means 13 for controlling the amount of the liquid flowing out from the outlet 12 to maintain the liquid level L at a predetermined height.

Adjusting the pipe diameter and the flow rate without providing these special devices may be regarded as a kind of the flow rate adjusting means 13. Although the liquid outlet 12 is provided below the layer 10 in the drawing, the liquid outlet 12 may be provided at an appropriate location as long as air bubbles are not mixed therein.
【００２６】そして、上記槽１０内の上部には一部また

てある。In the embodiments shown in FIGS. 1 and 2, the swirling flow preventing plate 14 is formed as a cross-shaped plate, and is entirely immersed at a predetermined depth from the liquid level. Accordingly, a swirling flow is generated in the tank 10, but the swirling flow cannot be swirled when the swirling flow collides with the swirling flow prevention plate 14, so that the liquid does not swirl above the swirling flow prevention plate 14.

The upper end is made substantially coincident with the liquid surface, and the swirl flow prevention plate 14 shown by a broken line is formed by immersing a lower part of the plate below the liquid surface. In the present invention, any of these methods is adopted. However, except for the case indicated by the solid line, it may be necessary to provide a bubble discharge port 15 described later at a plurality of locations on the peripheral surface of the tank 10 corresponding to the portion partitioned by the swirling flow prevention plate 14. .

出口１５より溢れ出るものである。Further, in the present invention, the tank 10 is provided with a bubble discharge port 15 above the liquid level L. If the bubble discharge port 15 is simply provided with an opening, the bubbles are sequentially generated, rise on the liquid surface of the tank 10, and eventually overflow from the bubble discharge port 15.

The air bubbles float upward at a specific gravity, reach the liquid level, and overflow from the air outlet 15. Then, the liquid from which bubbles have disappeared flows out from the liquid outlet 12.

適宜調整する等の運転管理も容易なものである。However, in the present invention, the tank 10 is limited to a tank having an open upper portion. The open type is an apparatus in which the tank 10 is opened to the atmosphere (of course, it is not necessary to positively deny that a lid is attached, but it is sufficient that the liquid level is at atmospheric pressure by communicating with the atmosphere). It can be easily configured, and the operation management such as configuring a complicated flow path and appropriately adjusting the flow velocity of each flow path is also easy.

い。Further, in the illustrated example, the upper end of the lid 10c is open, but can be closed and closed (a pressurized closed type is also possible). In addition, in the conventional cyclone, when the bubbles are clogged, the liquid surface in contact with the bubbles is swirling, so that the bubbles are caught in the liquid again and the efficiency is reduced.
In the case of the present invention, the efficiency does not decrease because the liquid surface does not turn.
