Description

【０００１】
【発明の属する技術分野】
本発明は、主としてダムや湖沼など、水質浄化のために水中に空気を噴出させて水を循環させる散気装置に関するものである。
【０００２】
【従来の技術】
従来、閉鎖海域や、湖沼の水質改善を目的とした散気装置によるばっ気循環が行われている。
散気装置の作用は、散気装置から出る気泡の上昇により生じる連続した上昇流を駆動力として、湖沼等の全体の水を混合循環させて温度躍層の発達を抑え、深層の貧酸素化を防止したり、底泥からのリンの溶出による水質の悪化を解消させるものである。また、同時に藻類を光の到達しない深層に移送させることにより藻類、特にアオコ等の藍藻類の増殖を抑制するものである。
【０００３】
従来の散気装置は、円周状に配置した複数のノズルから圧縮空気を真上に噴出させて空気によって水を連行しながら浮上させているので、空気はノズルの上方にのみ上昇している。上昇流を発生させて水を循環させるという観点からは、空気をできるだけ広い範囲にわたって上昇させることが好ましく、従来の散気装置はエネルギー効率が良くなかった。
【０００４】
【発明が解決しようとする課題】
簡単な散気装置によって気泡が上昇する面積を拡大し、効率よく水を循環させることができる装置を得ることをその課題とするものである。
【０００５】
【課題を解決するための手段】
本発明は、圧縮空気導入部の上に吸水部を配し、さらにその上に散気部を設け、圧縮空気導入部には圧縮空気導入管を設け、吸水部は横方向からと下方向から水が導入されるようにし、さらに散気部にはスパイラルガイドを配し、圧縮空気導入部の上面と散気部の下面の間に形成された吸水部の中心部には水が通過する開口を設け、吸水部の周辺は開放し、開口と周辺の間には中心部の開口に向けて水が周辺から流入するように、整流板を中心部の開口に向って適宜間隔を置いて設け、整流板間に圧縮空気分配管の先端を中心部の開口に向けて取付けた渦流式散気装置からなる。
【０００６】
【発明の実施の形態】
本発明の渦流式散気装置は、上下方向に３段の部分から構成され、その最下部には圧縮空気導入部１、その上には吸水部２、そして最上部には散気部３からなる。そしてそれらの各部は次のごとき構成からなる。
最下部の圧縮空気導入部１には圧縮空気導入管４が設けてあり、その圧縮空気導入管４は装置の中心部に導入され、そこから圧縮空気分配管５が上部の吸水部２に向かって分散配置されている。
【０００７】
次に圧縮空気導入部１の上方に設けた吸水部２には、多数の整流板６が図４に示すように吸水部２の全周にわたって均等に曲線状に配置されており、それらの各整流板６により形成された各空間内に前述の圧空分配管５の先端部が突出し、それらの先端部は夫々中心方向に向かって曲げられており、先端にはノズル２０が取付けられている。
【０００８】
また、この吸水部２の底部中央には水が上方に吸引され、導入される開口７が穿設されている。
ついで最上部の散気部３には、その外周に複数の部屋に区切られた浮力体８が設置され、その上方にはバルブ９が取付けられて空気の導入、排出を適宜行うようにしている。
【０００９】
また浮力体８の側面には連通孔１０が多数穿設され、水の浮力体８への流入・排出が可能のようにできている。そして浮力体８の内側にはスパイラルガイド１１が中心体１２の側面に多数均等に取付けされ、その先端側は浮力体８の内壁に固定している。中心体１２の下端を逆円錐体とすれば、水の上昇抵抗を減じるのに効果的である。
【００１０】
また浮力体８およびスパイラルガイド１１の上方は外部に開放状態となっている。なお、浮力体８は、本発明の渦流式散気装置の設置や移動をより容易にするためのものであるので、圧縮空気により水を効率よく循環混合させるという機能には直接関係がないので、散気部に浮力体を設けずに、単に筒状部材を設けてもよい。
【００１１】
以上が本発明の渦流式散気装置の構成であり、次にその作用について以下説明する。
本発明の渦流式散気装置を設置する際には、まず浮力体８にバルブ９を通して空気を入れ、その中の水を浮力体８に設けた連通孔１０から排出させることにより水上に浮上させて所定位置まで運び、次いで浮力体８内の空気を排出しながら連通孔１０から水を浮力体８内に導入することにより水中の適当位置まで降下させる。
【００１２】
次いで適当位置に係留するために、水底に位置させた重錘に連結したロープの他端を該渦流式散気装置に連結し、上方への移動をそれらのロープにより抑止し、一方それらのロープを張設するために該渦流式散気装置にバルーン等の浮力発生体を取付けたり、又は浮力体８内への空気量を増加させて積極的に浮力を生じさせること等により渦流式散気装置を上方に常に引張られる状態にして定位置に係留するようにする。
【００１３】
浮力体８を設けない場合は、揚重機を有する船舶で渦流式散気装置を所定位置まで運び、次いで揚重機により水中の適当位置まで吊り降ろし、水底に位置させた重錘に連結したロープの他端を該散気装置に連結し、該散気装置にバルーン等の浮力発生体を取付けることにより設置する。
さて、本発明の散気装置による水の循環混合を行う場合には、先ず圧縮空気を圧縮空気導入管４に導入し、その圧縮空気は圧縮空気分配管５を経由して吸水部２に導出される。
【００１４】
そこで圧縮空気分配管５の先端のノズル２０は中心方向に曲げて向けているから圧空の噴出により、気泡が発生し、気泡は中心部付近で上昇し始めるので、周辺の水は整流板６に沿って周囲から中心方向に向けて導入される。
それと同時に当然ながら開口７を通って下方の水も上方に運ばれることになる。したがって吸水部２では水は横方向からと下方から同時に吸引されて上方に運ばれることになる。
【００１５】
次に、上方、即ち散気部３に上昇した気泡は、スパイラルガイド１１に至り、スパイラルガイド１１に沿って斜め上方に水面方向に向かって渦流状に上昇することになる。この場合スパイラルガイド１１を使用したから気泡がスパイラルガイド１１から斜め上方に噴出し、噴出される気泡の面積が広がり上昇流を発生させる面積を広げることができる。
【００１６】
さらに、スパイラルガイド１１を固設している中心体１２を特に設けたために、一般には中心部分の上方ではどうしても上昇する気泡がオーバーラップして上昇流を発生させる効率が悪かったところ、この中心体１２の存在により渦流式散気装置の上方では上記のごとく上昇する気泡のオーバーラップ現象が殆ど生じず、丁度平行的に万遍なく気泡が上昇して効率よい散気現象を生ずるようにすることができ、そのように中心体１２の直径等を設計することができるのである。また浮力体８の中を複数の部屋に仕切ることにより、浮力の微細変更を可能にすることができる。
【００１７】
【発明の効果】
▲１▼．本発明の散気装置は、圧縮空気導入部、吸水部および散気部を下から上に順次配列したことにより、全体としてコンパクトに作ることができ、かつこの配列によって効率的に上昇流を発生させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to an air diffuser that circulates water by jetting air into water for purification of water quality such as dams and lakes.
[0002]
[Prior art]
Conventionally, aeration is being performed by a diffuser for the purpose of improving the water quality of closed seas and lakes.
The function of the diffuser is to suppress the development of the thermocline by mixing and circulating the whole water such as lakes and the like using the continuous upward flow generated by the rising of the bubbles coming out of the diffuser as the driving force. It prevents the deterioration of water quality due to the elution of phosphorus from the bottom mud. At the same time, the growth of algae, particularly cyanobacteria such as blue-green algae is suppressed by transferring algae to a deep layer where light does not reach.
[0003]
In the conventional air diffuser, compressed air is ejected from a plurality of circumferentially arranged nozzles and floats while entraining water by the air, so that the air rises only above the nozzles. . From the viewpoint of circulating the water by generating an upward flow, it is preferable to raise the air over as wide a range as possible, and the conventional air diffuser is not energy efficient.
[0004]
[Problems to be solved by the invention]
It is an object of the present invention to obtain a device capable of expanding the area where bubbles rise by a simple air diffuser and circulating water efficiently.
[0005]
[Means for Solving the Problems]
In the present invention, a water absorption part is arranged on the compressed air introduction part, a diffusion part is further provided thereon, a compressed air introduction pipe is provided in the compressed air introduction part, and the water absorption part is laterally and downward as water is introduced, still more spraying component coordinated spiral guide, the center of the water-absorbing portion formed between the lower surface of the upper surface and the spraying component of the compressed air introduction section through the water opening Provide a rectifying plate at an appropriate interval toward the center opening so that water flows from the periphery toward the center opening between the openings and the periphery. The vortex air diffuser is attached between the flow straightening plates with the front end of the compressed air distribution pipe facing the opening at the center .
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The vortex-type air diffuser of the present invention is composed of three stages in the vertical direction, the compressed air introduction part 1 at the bottom, the water absorption part 2 above it, and the air diffusion part 3 at the top. Become. Each part has the following structure.
A compressed air introduction pipe 4 is provided in the lowermost compressed air introduction section 1, and the compressed air introduction pipe 4 is introduced into the center of the apparatus, from which the compressed air distribution pipe 5 is directed to the upper water absorption section 2. Are distributed.
[0007]
Next, in the water absorption part 2 provided above the compressed air introduction part 1, a large number of rectifying plates 6 are arranged uniformly in a curved shape over the entire circumference of the water absorption part 2 as shown in FIG. The leading ends of the above-described compressed air distribution pipes 5 protrude into the spaces formed by the rectifying plates 6, and the leading ends are bent toward the center, respectively, and a nozzle 20 is attached to the leading end.
[0008]
Further, an opening 7 through which water is sucked upward and introduced is formed in the center of the bottom of the water absorbing portion 2.
Next, the uppermost diffuser 3 is provided with a buoyant body 8 divided into a plurality of rooms on the outer periphery thereof, and a valve 9 is attached above the buoyant body 8 so as to appropriately introduce and discharge air. .
[0009]
A large number of communication holes 10 are formed in the side surface of the buoyancy body 8 so that water can flow into and out of the buoyancy body 8. A large number of spiral guides 11 are evenly attached to the side surface of the center body 12 inside the buoyancy body 8, and the tip side is fixed to the inner wall of the buoyancy body 8. If the lower end of the center body 12 is an inverted cone, it is effective to reduce the resistance to water rise.
[0010]
The upper part of the buoyancy body 8 and the spiral guide 11 is open to the outside. Note that the buoyancy body 8 is intended to facilitate the installation and movement of the vortex diffuser of the present invention, and is not directly related to the function of efficiently circulating and mixing water with compressed air. A cylindrical member may be simply provided without providing a buoyancy body in the air diffuser.
[0011]
The above is the configuration of the vortex diffuser of the present invention, and the operation thereof will be described below.
When installing the vortex diffuser of the present invention, first, air is introduced into the buoyancy body 8 through the valve 9 and the water therein is discharged from the communication hole 10 provided in the buoyancy body 8 so as to float on the water. Then, the water is introduced to the buoyancy body 8 from the communication hole 10 while discharging the air in the buoyancy body 8 and then lowered to an appropriate position in the water.
[0012]
Next, in order to moor at an appropriate position, the other end of the rope connected to the weight located at the bottom of the water is connected to the vortex diffuser, and the upward movement is restrained by the rope, while the ropes For example, a buoyancy generator such as a balloon is attached to the vortex diffuser, or the buoyancy is actively generated by increasing the amount of air into the buoyancy body 8. The device is always pulled upward and is anchored in place.
[0013]
When the buoyant body 8 is not provided, the vortex diffuser is carried to a predetermined position on a ship having a lifting machine, then suspended to an appropriate position in the water by the lifting machine, and a rope connected to a weight positioned at the bottom of the water. The other end is connected to the air diffuser, and a buoyancy generator such as a balloon is attached to the air diffuser.
When water is circulated and mixed by the air diffuser of the present invention, compressed air is first introduced into the compressed air introduction pipe 4 and the compressed air is led to the water absorption section 2 via the compressed air distribution pipe 5. Is done.
[0014]
Therefore, since the nozzle 20 at the tip of the compressed air distribution pipe 5 is bent toward the center, bubbles are generated by the jet of compressed air, and the bubbles start to rise near the center. It is introduced from the circumference to the center direction.
At the same time, naturally, the lower water is also carried upward through the opening 7. Therefore, in the water absorption part 2, water is simultaneously sucked from the lateral direction and from below and is carried upward.
[0015]
Next, the air bubbles rising upward, that is, in the air diffuser 3 reach the spiral guide 11, and rise in a vortex shape toward the water surface obliquely upward along the spiral guide 11. In this case, since the spiral guide 11 is used, the bubbles are ejected obliquely upward from the spiral guide 11, and the area of the ejected bubbles is expanded and the area for generating the upward flow can be expanded.
[0016]
Further, since the central body 12 to which the spiral guide 11 is fixed is particularly provided, the efficiency of generating the upward flow due to the overlapping of the rising bubbles is generally low above the central portion. Due to the presence of 12, the bubble overlapping phenomenon that rises as described above hardly occurs above the vortex air diffuser, and the bubbles rise just uniformly in parallel to generate an efficient air diffusion phenomenon. Thus, the diameter of the central body 12 can be designed as such. Further, by partitioning the buoyancy body 8 into a plurality of rooms, the buoyancy can be finely changed.
[0017]
【The invention's effect】
(1). The air diffuser of the present invention can be made compact as a whole by arranging the compressed air introduction part, the water absorption part and the air diffusion part sequentially from the bottom to the top, and efficiently generates an upward flow by this arrangement. Can be made.
(2). Since the vortex-type air diffuser of the present invention is configured to three-dimensionally take in the water that rises as the bubbles rise from the entire circumference and from below, the water inflow area into the device is large, and The amount of water intake can be increased, and the inflow resistance of water can be greatly reduced.
(3). The central body with a fixed spiral guide can have an appropriate diameter so as to prevent the bubble from overlapping, and the central body can be made into an inverted cone to reduce the resistance to water rise. it can.
[0018]
Further, by providing, for example, a cylinder or the like on the upper part of the central body, bubbles can be discharged more widely in the horizontal direction by the spiral guide, and the rising flow rate of water can be increased.
(4). In the air diffuser, a buoyant body, a spiral guide, and a central body are sequentially arranged from the outside, and these three members are integrally fixed. The central body is capable of preventing overlap above the rising bubbles. The guide can increase the area by diffusing the rising bubbles and enable the generation of a vortex. Furthermore, the buoyancy body can freely reduce the buoyancy by putting air in it to increase the buoyancy and water.
[0019]
In this way, the buoyancy body, the spiral guide and the central body having the respective effects can be integrated through the spiral guide so that they can be made compact and the installation volume can be minimized and the effects of the three can be sufficiently achieved.
