Description
本発明は、閉鎖系水域におけるヘドロ等の堆積物や水中の有機系汚染物に対して、表層の酸素を多く含んだ水を深層部に対して連続的に供給し、循環流を形成させ常在微生物により水質を浄化させる装置に関する。
さらに具体的には、水面に浮遊し、例えば湖沼、河口域、ダム、貯水池、溜池、養殖場などの閉鎖性水域の淡水又は海水の浄化を図る浮遊式水質浄化装置に関するものである。In the present invention, water containing a large amount of surface layer oxygen is continuously supplied to deep layers to deposits such as sludge and water-borne organic pollutants in a closed water area, thereby forming a circulating flow. The present invention relates to an apparatus for purifying water quality by using microorganisms.
More specifically, the present invention relates to a floating water quality purification apparatus that floats on the water surface and purifies fresh water or seawater in closed water areas such as lakes, estuaries, dams, reservoirs, reservoirs, and farms.
湖沼、ダム、養殖場などの閉鎖性水域では、水の流れが殆どなく、酸素が十分に水中特に水底側に供給されず、アオコの発生やヘドロ等が蓄積し易くなる。このため、例えば、曝気装置、攪拌装置、酸素供給ポンプなどを使用して、水中に酸素を供給して水の浄化を図る技術が知られており、一部実用化されている。（例えば特許文献１及び２） In closed water areas such as lakes, dams, and farms, there is almost no flow of water, and oxygen is not sufficiently supplied to the bottom of the water, particularly water bottoms. For this reason, for example, a technique for purifying water by supplying oxygen into water using an aeration apparatus, a stirring apparatus, an oxygen supply pump, or the like is known and has been partially put into practical use. (For example, Patent Documents 1 and 2)
しかしながら、従来の曝気装置、攪拌装置、酸素供給ポンプなどの装置を用いて、閉鎖性水域の水中に空気又は酸素を供給して水の浄化を図る技術においては、装置の構造が複雑で、エネルギー消費が大きく、さらに継続的なメンテナンスが必要でその結果多大なコストがかかる等の問題があった。 However, in the technology for purifying water by supplying air or oxygen into water in a closed water area using devices such as conventional aeration devices, stirring devices, oxygen supply pumps, etc., the structure of the device is complicated, and energy There is a problem that consumption is large and further maintenance is required, resulting in high costs.
また、特許文献１に示された技術は、浮遊式で漏斗状の下部に設けられたシャフトにプロペラを備えたもので昇降流水路を形成し水底部に酸素を供給し、水質を浄化するシステムであり一定の効果があった。しかしながら、閉鎖水系においては水中や上層部にゴミ及び浮遊物等があり、プロペラに絡まり停止や破損等の多大なメンテナンスを要するという問題点があった。 In addition, the technique disclosed in Patent Document 1 is a system that purifies water quality by forming an up-down flow channel by supplying a propeller to a shaft provided in a floating and funnel-shaped lower portion and supplying oxygen to the bottom of the water. There was a certain effect. However, in the closed water system, there is a problem that there are dust and floating matters in the water and the upper layer portion, and it is entangled with the propeller and requires a great deal of maintenance such as stoppage or breakage.
本発明は、前述の課題に鑑みその課題を解決すべく鋭意検討し、エジェクター式のジェットポンプ駆動により水取り入れ口から取り入れた水の急激な下降水流を発生させ、浮遊体上部からの空気を吸引同伴させて下部への大量で急速な空気を含む下降水流を起こすことを特徴とするものである。 In view of the above-mentioned problems, the present invention has been intensively studied to solve the problems, and generates an abrupt descending flow of water taken from the water intake by an ejector-type jet pump drive, and sucks air from above the floating body. It is characterized by causing a descending water flow including a large amount of rapid air to the lower part.
本発明は、水面上に浮遊させる上部側が拡がった漏斗状の浮体の構造で、該浮体には下方にシャフトを接続する。漏斗状の浮体の上部に設置したポンプ駆動により水流を発生させ、エジェクター部に供給し、その際に発生した吸引力を用いて空気を浮体上部より取り込んだ水とともに大量で強力な下降流を形成させる。その結果上部の比較的酸素濃度の高い水と空気とを水底部に連続的に供給することができる。また、水流の駆動部は水中に設置したプロペラではなく上部に設置したエジェクター式のジェットポンプ駆動であるため浮遊物やゴミ等が絡まったり詰まることを低減でき装置が停止することもない。 The present invention has a funnel-like floating body structure in which the upper side floating on the water surface is widened, and a shaft is connected to the lower body. A pump is installed at the top of the funnel-shaped floating body to generate a water flow and supply it to the ejector. Using the suction force generated at that time, air is drawn from the top of the floating body to form a large and powerful downward flow. Let As a result, water and air having a relatively high oxygen concentration at the top can be continuously supplied to the bottom of the water. In addition, since the water flow driving unit is not a propeller installed in water but an ejector jet pump installed in the upper part, it is possible to reduce the entanglement and clogging of floating substances and dust, and the apparatus does not stop.
本装置は基本的に浮遊式で自由に移動するが、通常は、基点より係留ロープによって陸上の基点に連結支持して用いる。また電源供給は装置上部に設置する太陽光発電又はケーブルによる外部電源を用いてもよい。 This device is basically floating and moves freely. Usually, it is connected to a land base point by a mooring rope from the base point. The power supply may be solar power generation installed on the upper part of the apparatus or an external power supply using a cable.
本発明によるポンプ駆動の下降水流発生水質浄化装置によれば、下降流シャフトを通じて水面上部の比較的酸素を多く含んだ水と空気を水中下部に送り込むことができる。下降流に対応して上昇流が生じることにより酸素を殆ど含んでいない水中下層の水を水面上に送り出して空気中の酸素を吸収させる循環流を形成させることができる。これによって、微生物に酸素を供給し閉鎖性水域における水の浄化を効率的に達成することができる。 According to the pump-driven lower precipitation flow generation water purification device of the present invention, water and air containing a relatively large amount of oxygen at the upper surface of the water surface can be sent to the lower part of the water through the downflow shaft. By generating an upward flow corresponding to the downward flow, it is possible to form a circulating flow in which water in the lower layer of the water that contains almost no oxygen is sent to the water surface to absorb oxygen in the air. As a result, oxygen can be supplied to the microorganisms to effectively purify the water in the closed water area.
以下、本発明をより具体的に説明する。ここで、図１は浮遊式水質浄化装置の側断面図である。 Hereinafter, the present invention will be described more specifically. Here, FIG. 1 is a side sectional view of the floating water purification apparatus.
図１において、浮遊式水質浄化装置は、水面に浮遊して、酸素を多く含んだ水面及び上層水とエジェクターにより吸引した空気とを水中に供給して水の浄化を図る装置である。 In FIG. 1, the floating water purification apparatus is an apparatus that purifies water by supplying the water surface and upper layer water that contains a large amount of oxygen and air sucked by an ejector to the water surface.
図１に示した浮遊式水質浄化装置は、漏斗状の浮体１、浮体１に取付けられた降下水を誘導するシャフト４、シャフト４の上部に取付けられたエジェクター６、エジェクターに高圧水を供給するポンプ５、浮体１の周囲に設けられた水取り入れ口３と浮体に取付けられた空気取り入れ口２などから主に構成されている。 The floating water purification apparatus shown in FIG. 1 supplies a funnel-shaped floating body 1, a shaft 4 that guides falling water attached to the floating body 1, an ejector 6 attached to the upper part of the shaft 4, and high-pressure water to the ejector. The pump 5 is mainly composed of a water intake port 3 provided around the floating body 1 and an air intake port 2 attached to the floating body.
浮体１は、水面上に浮遊するもので、内部は空洞か、または、水より比重の小さい材料を充填されたもので漏斗状の逆円錐曲面の形状を有している。
浮体の大きさは、浄化する水域の対象面積とエジェクター駆動ポンプの容量や重量等により選択されるが、通常は直径で６０ｃｍ〜２００ｃｍである。The floating body 1 floats on the water surface, and the inside is hollow or filled with a material having a specific gravity smaller than that of water and has a funnel-shaped inverted conical curved surface.
The size of the floating body is selected depending on the target area of the water area to be purified and the capacity and weight of the ejector drive pump, but is usually 60 cm to 200 cm in diameter.
浮体１には下方向にシャフト４が取付けられている。シャフト４は漏斗状の浮体の中心の下部でエジェクターの吐出部に直結されている。シャフトの長さは、１〜２０ｍの範囲で調整することで水域の深度が２〜３０ｍの範囲まで対応できる。 A shaft 4 is attached to the floating body 1 in the downward direction. The shaft 4 is directly connected to the discharge part of the ejector at the lower part of the center of the funnel-shaped floating body. By adjusting the length of the shaft in the range of 1 to 20 m, the depth of the water area can correspond to the range of 2 to 30 m.
エジェクターの上部に直結してエジェクターに吸引力をもたらすための高圧水を発生させるポンプが設置される。また、エジェクターの吸引部には空気取り入れ口に繋がったパイプが連結されている。
エジェクター駆動用のポンプの吐出容量は浮体の大きさに適合するものだが、通常は２０００〜２００００Ｌ／時間の範囲である。
エジェクターの口径は、通常、注入部の口径が直径５０ｍｍ〜１６０ｍｍでノズル部の口径が直径１０ｍｍ〜４０ｍｍの範囲である。A pump is installed that generates high-pressure water directly connected to the top of the ejector to bring suction to the ejector. A pipe connected to the air intake is connected to the suction part of the ejector.
The discharge capacity of the ejector pump is suitable for the size of the floating body, but is usually in the range of 2000 to 20000 L / hour.
The diameter of the ejector is usually in the range where the diameter of the injection part is 50 mm to 160 mm and the diameter of the nozzle part is 10 mm to 40 mm.
エジェクター駆動用のポンプは浮体の中で設置されているが、水面に設置する場合は喫水線以下になる。浮体は全体が防水処理をされており、水や海水などが進入することを防いでいる。ポンプを駆動する電力源として浮体上面に太陽電池が設置されている。また、陸上からケーブルにより外部電力を供給することも可能である。必要に応じてインバーター設備や蓄電池を設置してもよい。 The pump for driving the ejector is installed in the floating body, but when it is installed on the surface of the water, it becomes below the draft line. The entire floating body is waterproofed to prevent water and seawater from entering. A solar cell is installed on the upper surface of the floating body as a power source for driving the pump. It is also possible to supply external power from the land via a cable. You may install an inverter installation and a storage battery as needed.
本発明の浮遊式水質浄化装置は閉鎖系の水域内を自由に動き水質を浄化するものであるが、通常は基点から係留ロープによって繋がれている。 The floating water purification apparatus of the present invention moves freely in a closed water area and purifies water quality, but is usually connected by a mooring rope from a base point.
本発明の浮遊式水質浄化装置は、水域内に設置浮遊させて、供給電力によりエジェクター駆動ポンプにより強力な下降水流を発生させ下部に設置したエジェクターに減圧部を発生させる。エジェクターの吸引部分からは外部の空気が導入され水とあわされて酸素を多く含んだ流体として水域の底部に吐出される。装置外では上昇水流が起こり、酸素を多く含んだ上層の水を水中下層に供給する循環流水が浮遊式水質装置の周囲で生じ、常在微生物の活動を活発にし、閉鎖系の水域における水の浄化が効率的に達成される。 The floating-type water purification apparatus of the present invention is installed and suspended in a water area, generates a powerful descending water flow by an ejector drive pump using supplied power, and generates a decompression section in an ejector installed in the lower part. External air is introduced from the suction portion of the ejector and is discharged as water containing oxygen and discharged to the bottom of the water area. Outside the device, an updraft occurs, and circulating water that supplies oxygen-enriched upper water to the lower water layer is generated around the floating water quality device, activating the activities of resident microorganisms, and water in the closed system Purification is achieved efficiently.
本発明の浮遊式水質浄化装置によれば、ダム、湖沼、養殖場等の閉鎖系水域における水質の悪化やヘドロの蓄積等を、自動的にかつ簡便に浄化することができる。 According to the floating water quality purification apparatus of the present invention, it is possible to automatically and simply purify deterioration of water quality, accumulation of sludge, etc. in closed water areas such as dams, lakes, and farms.
