【発明の詳細な説明】
本発明は液体に気体を混合させて微粒気泡を発
生させる気液混合装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas-liquid mixing device that mixes gas with a liquid to generate fine bubbles.
従来、気液混合装置としては水中ポンプで液体
を噴出せしめ、通気孔から送られた気体を強制的
に差込ませて液体中に微粒気泡を発生させる装置
があるが、水深の深い所では膨大な動力を要する
ため、実質的に２ｍ未満の水深の浅い液中でしか
使用できず、その用途は極めて限られている欠点
があつた。 Conventionally, gas-liquid mixing devices use submersible pumps to eject liquid, and gas sent through vents is forced into the liquid to generate microbubbles in the liquid. Since it requires a large amount of power, it can only be used in shallow liquids of less than 2 meters in depth, and its uses are extremely limited.
前記欠点を解消する装置も提案されているが
（例えば実公昭52−6955号等）、水深２ｍ以上の液
中でも有効に機能するものは、大規模な曝気には
適さず、しかも液体排出口および気体排出口とも
に幅狭く、複雑な構成になつているため、糸屑そ
の他の屑物による目詰りが起り易く、このため駆
動モーターに過負荷がかかり、モーター寿命を縮
めてしまい、しかも一旦屑物がからまると除去す
るのが困難で、再生利用ができない欠点があつ
た。 Devices that solve the above drawbacks have been proposed (for example, Utility Model Publication No. 52-6955, etc.), but devices that function effectively in liquids at a depth of 2 m or more are not suitable for large-scale aeration, and they do not have a liquid outlet or Because the gas exhaust ports are narrow and have a complicated configuration, they are easily clogged with lint and other debris, which overloads the drive motor and shortens the motor's life. Once entangled, it is difficult to remove and cannot be recycled.
更に、第１図に示すようにパイプ先端部にスク

に沿つた下方向に限られること、また装置の設定
は、せいぜい水中に斜め方向でしか行うことがで
きず垂直方向に設置できないこと等、その用途は
極めて限られる他、エネルギーの消費も大きいと
いう欠点があつた。 Furthermore, as shown in FIG. 1, a device has been proposed in which a screw B is attached to the tip of a pipe, and air is blown from the pipe by a water flow caused by the rotation of the screw. However, with this device, gas cannot be injected in the form of extremely fine particles, the direction of water flow is limited to the downward direction along the pipe, and the device can only be set up diagonally into the water, not vertically. Its uses are extremely limited, such as the inability to install it in any direction, and it also has the disadvantage of consuming large amounts of energy.
本発明者はこれら従来装置の欠点を解消し、汎
用性が高くしかも取扱いの簡便な装置を得んとし

を提案している（特願昭58−32890号、同58−
76256号、同58−76257号）。 The inventor of the present invention sought to eliminate the drawbacks of these conventional devices and create a device that is highly versatile and easy to handle, and as a result of intensive research, he came up with the idea of utilizing the negative pressure generated by overflow of liquid. Several types of devices have already been proposed (Patent Application No. 58-32890;
76256, 58-76257).
本発明者は更に検討を重ねた結果、一層効率的
に気液を混合できる装置を完成させるに至つた。 As a result of further studies, the present inventor has completed an apparatus that can mix gas and liquid even more efficiently.
以下実施例を示す第２図〜第３図により本発明
の内容を説明する。 The content of the present invention will be explained below with reference to FIGS. 2 and 3 showing examples.

要により通気パイプ１の下端開口部には盲板４が
配されている気液混合装置である。 The present invention comprises a ventilation pipe 1 having a gas installation port 1a above, and a curved impeller 2 attached to the ventilation pipe 1.
A plurality of gas jet ports 3, 3, 3... are bored in the ventilation pipe 1 along the back surface 2a in the rotation direction of the impeller 2, or in the ventilation pipe 1 along the back surface 2a and the back surface 2a in the rotation direction of the impeller 2. This is a gas-liquid mixing device in which a blind plate 4 is arranged at the lower end opening of the ventilation pipe 1 if necessary.
本発明装置において、通気パイプ１の形状、径
および長さは任意であり、必要に応じて適宜定め
ればよい。 In the device of the present invention, the shape, diameter, and length of the ventilation pipe 1 are arbitrary, and may be determined as necessary.
この通気パイプ１は回転機構（図中省略）に連

連結に使用する場合にはパイプ１の上方側部１ｂ
に設けるようにしてもよい（第３図参照）。 This ventilation pipe 1 is connected to a rotation mechanism (not shown) and is rotatable. Further, the diameter of the gas intake port 1a provided in the ventilation pipe 1 is not particularly limited, as long as it has a sufficient area for ventilation, and the number thereof is not limited to one. This gas intake port 1a may be provided above the ventilation pipe 1. For example, the upper end opening of the pipe 1 may be used as is, or when the upper end of the ventilation pipe 1 is used for connection with a rotating mechanism. Upper side part 1b of pipe 1
(See Figure 3).

意の向きに設定することができる。 The curved impeller 2 is fixed to the lower side 1c of the ventilation pipe 1 by suitable means, and the number of impellers may be arbitrarily determined from one to more, but the most stable result is 4 to 8 impellers. This is the case when they are installed radially. The impeller 2 may be plate-shaped or may be of a hollow type (see FIG. 2) attached to the pipe 1 so as to communicate the internal cavity with the cavity of the ventilation pipe 1. Preferably, it has a somewhat twisted shape. It is preferable for the convex curved surface 2b of the impeller 2 to face the direction of rotation of the ventilation pipe 1, that is, the direction of flow of the liquid, in order to sufficiently blow gas into the liquid using negative pressure. That is, when the ventilation pipe, and thus the impeller, rotates clockwise as shown in FIG. 2, the convex curved surface 2b of the impeller is installed upward, and conversely, when the ventilation pipe 1 rotates in the opposite direction from the clockwise direction, the convex curved surface 2b of the impeller is installed upward. It is preferable to attach the convex curve 2b downward in order to blow in the gas in the form of fine particles. However, the convex curved surface may be reversed for the purpose of increasing liquid flow, and the curved surface can be set in any direction.
インペラー２の回転による液体の流動が上向き

なお前記盲板４は上記の場合に限らず第３図の構
成でも通気パイプ１に配することができる。 When the liquid flows upward due to the rotation of the impeller 2 (see FIG. 2), it is necessary to arrange a blind plate 4 at the lower end opening of the ventilation pipe 1 to prevent the liquid from entering the inside of the pipe 1. This blind plate 4 is fitted with a size matching the diameter of the lower end opening,
It may be fixed by adhesive or other fixing means.
Note that the blind plate 4 is not limited to the above case, but can also be arranged on the ventilation pipe 1 in the configuration shown in FIG.

させる。 The device of the present invention is used by connecting the top of the ventilation pipe 1 to the rotating mechanism as described above. The rotation mechanism rotates the ventilation pipe 1, which causes the impeller 2 to rotate in the liquid and generate a vortex,
Negative pressure is generated in the liquid on the back surface of the impeller 2 in the rotating direction, and the gas that flows into the pipe 1 from the gas intake port 1a is ejected from the gas ejection holes 3, 3, 3, . . . and mixed into the vortex. The mixed gas generates extremely fine bubbles in the liquid due to the vortex and the shearing force of the impeller 2.
