同５２−２２９５３）。[Prior Art] A gas-liquid device in which a porous drum is provided in a tank body so as to be submerged in water, and gas is supplied under pressure into the drum and the drum is rotated to eject air bubbles into the liquid from the circumferential surface of the drum. Contact devices are known (for example, Japanese Patent Publication No. 52-21991.
52-22953).

いう特長を有している。Such a gas-liquid contact system using a porous cylindrical drum includes a vertical type in which the drum is installed so that its axial direction is substantially vertical, and a horizontal type in which the drum is installed horizontally. The former vertical type (for example,
1991) has a simpler drum pivot mechanism than the latter horizontal type, and has the advantage of being particularly suitable for small-sized and small-capacity specifications.

率が低いものとなっていた。[Problems to be Solved by the Invention] However, in the conventional vertical rotating drum type gas-liquid contact device, since the drum is cylindrical as shown in FIG. The ejected air bubbles tend to rise densely near the peripheral surface of the drum, and therefore,
It was difficult for the bubbles to be dispersed throughout the entire area inside the cage, and the bubbles tended to meet and coalesce to become coarse, resulting in a low gas-liquid contact efficiency.
［問題点を解決するための手段］
本発明は、縦型回転ドラムを備えた気液接触装置におい
て、ドラムとして下方に向って拡径する形状のものを採
用したものである。[Means for Solving the Problems] The present invention is a gas-liquid contact device equipped with a vertical rotating drum, in which the drum has a shape that expands in diameter downward.
なお、気体の供給管は、例えばドラム底部の中央部より
ドラム内に装入される。Note that the gas supply pipe is inserted into the drum, for example, from the center of the bottom of the drum.

な気泡となる。[Function] In the gas-liquid contact device of the present invention, the gas supplied into the drum from the gas supply pipe is sequentially ejected from the openings provided on the circumferential surface of the drum. At this time, the drum is being rotated, and the gas ejected from the opening is subjected to shearing action, etc., and becomes minute bubbles.
而して、本発明においては、ドラムが下方に向って拡径

（イ） 開口が水平方向に分布したものとなる。According to the present invention, since the drum has a shape whose diameter increases downward, (a) the openings are distributed horizontally.
（ロ） ドラム下部では、周速が大台くなり、液体の回
転速度も大きくなる。これにより、液体の遠心力が大き
くなって、気泡がドラムから遠くまで分散される。(b) At the bottom of the drum, the circumferential speed increases and the rotational speed of the liquid also increases. This increases the centrifugal force of the liquid and disperses the air bubbles further away from the drum.
（ハ） 従って、気泡同志の合体が防止される。(c) Therefore, coalescence of bubbles is prevented.
（ニ） 気泡の液体中での滞留時間が長くなる。(d) The residence time of bubbles in the liquid becomes longer.
等の作用により、微細な気泡が広汎に分散するようにな
り、気液接触効率が高められる。Due to these effects, fine air bubbles become widely dispersed and the gas-liquid contact efficiency is increased.

Further, the drum bottom plate 18a is provided with an opening through which the gas supply pipe 28 is inserted, and a sliding member 30 is provided at the edge of this opening to prevent the lower end of the drum 18 from rotating. It has become a central pillar of the

８が接続されている。In the device of this embodiment, a truncated conical partition wall 32 having a diameter smaller than that of the drum 18 is suspended from the canopy portion 18b of the drum 18. This partition wall 32 is smaller in height than the drum 18, and the lower end of the partition wall 32 and the drum bottom plate 1
A communicating portion 34 is formed between the connecting portion 8a and the connecting portion 8a. Furthermore, a passing pressure loss is applied to the gas flow rising between the partition wall 32 and the inner circumferential surface of the drum 18, so that the gas maintains a small pressure (static pressure) as it reaches the upper part. Aperture 36 for
are set up in multiple stages. The lower part of the gas supply pipe 28 is T-shaped, and the flexible tube 3
8 are connected.

。In the gas-liquid contact device having such a configuration, when gas is supplied into the rotating drum 18 through the flexible tube 38 and the gas supply pipe 28 and the motor 16 is rotated, the gas goes around the communication portion 34 at the lower end of the partition wall 32. The nozzle 2 rises between the partition wall 32 and the inner periphery of the drum 18, and
It is ejected from 4. Then, due to the shearing action caused by the rotation of the drum 18, it is finely divided into fine bubbles.
而して、本発明では、ドラム１８が下方はど拡径してい
るので、開口２２（ノズル２４）が水平方向に分布した
ものとなり、それだけ槽体内の水平方向の広い範囲にわ
たって気泡が分散するようになる。According to the present invention, since the diameter of the drum 18 is expanded in the downward direction, the openings 22 (nozzles 24) are distributed in the horizontal direction, and the bubbles are dispersed over a wide range in the horizontal direction inside the tank. It becomes like this.
また、ドラム１８を回転させると、ドラム１８外周に接
している液体も所要の周方向の回転力を得て渦巻き状に
循環を行なうようになるが、本発明では、下方はどドラ
ム径が大きいので、ドラム下方はど周速が大きくなる。Furthermore, when the drum 18 is rotated, the liquid in contact with the outer periphery of the drum 18 also obtains the required rotational force in the circumferential direction and circulates in a spiral shape, but in the present invention, the lower drum diameter is larger. Therefore, the circumferential speed increases in the lower part of the drum.
そうすると、槽体内の液体は、ドラム下部はど高速で周
回するようになり、ドラム軸心から遠ざかる方向への速
度も、ドラム下部はど速くなる。Then, the liquid in the tank will circulate at a higher speed in the lower part of the drum, and the speed in the direction away from the drum axis will also be faster in the lower part of the drum.
そのため、この液体流中に噴出された気泡も、ドラム下
部はど大きな速度でドラム軸心から遠ざかるようになる
。Therefore, the air bubbles ejected into the liquid stream also cause the lower part of the drum to move away from the drum axis at a high speed.
このようにして、本発明によれば、第３図に示す如く、
気泡がドラム軸心から遠い箇所にも到達するようになり
、気泡の分散度が極めて高いものとなる。なお、第４図

では気泡はほとんど存在しない。In this way, according to the present invention, as shown in FIG.
The air bubbles reach locations far from the drum axis, and the degree of bubble dispersion becomes extremely high. Note that FIG. 4 is shown as a comparative example, and schematically shows the state of bubble dispersion in a cylindrical drum type gas-liquid contact device. As shown in FIG. 4, in the cylindrical drum 38A, air bubbles spread only to a portion close to the drum axis, and there are almost no air bubbles near the wall surface of the tank body 10.
特に、本実施例では、絞り３６が多段に設けられており

ムから遠ざかるようになり、気泡の分散度が一層高いも
のとなる。In particular, in this embodiment, the throttles 36 are provided in multiple stages, and due to the pressure loss when passing through the throttles 36, the gas rising between the partition wall 32 and the inner circumferential surface of the drum 18 is reduced as it flows upward. Retention pressure decreases. Therefore, by appropriately adjusting the opening degree of the throttle 36, high-pressure gas can be ejected from the nozzle below the drum. In this way, the bubbles ejected from below the drum will move away from the drum more quickly, and the degree of dispersion of the bubbles will be even higher.

化する。Note that the aperture 3 is adjusted so that the difference between the water pressure and the gas pressure inside and outside the drum 18 in each nozzle 24 is approximately equal.
It is also possible to adjust the opening degree of 6. In this case, it becomes possible to eject an equal amount of gas per unit time from each nozzle 24, and the diameters of bubbles generated from each nozzle 24 are made equal.
なお、本実施例装置の運転開始前の状態にあっては、ド

１８外に排出される。Note that before the apparatus of this embodiment starts operating, the drum 18 contains liquid. This liquid is pushed by the gas supplied from the gas supply pipe when the apparatus starts operating, and is also discharged out of the drum 18 by the rotational centrifugal force of the drum 18.
上記実施例では、ノズル２４を突設しているので、ドラ

ム１８を回転させると、ドラム１８の側周に接している
液体もドラム１８と共に回転するが、ドラム１８の表面
から遠ざかるにつれて液体の速度は低下してくる。In the embodiment described above, since the nozzle 24 is provided in a protruding manner, the gas is ejected from the cylinder where the speed of the liquid rotating together with the drum 18 is reduced, which increases the shearing effect of the ejected gas and makes the bubbles smaller. It has the effect of becoming. That is, when the drum 18 is rotated, the liquid in contact with the side circumference of the drum 18 also rotates with the drum 18, but the speed of the liquid decreases as it moves away from the surface of the drum 18.
従って、ノズル２４の先端では、ドラム１８の表面に比
べ、液体との相対速度差が大きくなり、噴出される気体
に大きな剪断力を作用させることが可能となるのである
。Therefore, the relative velocity difference between the tip of the nozzle 24 and the liquid is larger than that at the surface of the drum 18, and it becomes possible to apply a large shearing force to the ejected gas.
また、上記実施例では、ドラム底板１８ａが摺動部材３
０を介して気体供給管２８に枢支される構成となってお

転が行なえるという効果がある。Further, in the above embodiment, the drum bottom plate 18a is connected to the sliding member 3.
The drum 18 is supported by the gas supply pipe 28 via the gas supply pipe 28, and the drum 18 is supported at two places, upper and lower, and has the effect of being able to rotate stably.
なお、上記実施例ではドラム１８は切頭円錐形であるが

８に遊嵌するボス部材を固設するようにしても良い。In the above embodiment, the drum 18 has a truncated conical shape, but the present invention is not necessarily limited to this. For example, a conical shape or one whose diameter expands in a stepwise manner can also be adopted. Moreover, it does not have to be cylindrical, and may be polygonal. Furthermore, in the present invention, the bottom plate of the drum is not essential, and the drum may have a lid and no bottom. In this case, spokes are provided at the bottom end of the drum to extend in the radial direction. Gas supply pipe 2 at the tip of the spoke
A boss member that loosely fits into 8 may be fixedly provided.
