　本発明は、揚水管の下端に揚水ポンプを備える揚水システムと、その揚水システムに用いる揚水管と、水頭差を有する管路に導かれた水で水車を回転させて発電機を駆動することにより発電する水力発電システムと、送水装置に接続される送水管を備える送水システムに関する。 The present invention provides a pumping system having a pumping pump at the lower end of a pumping pipe, a pumping pipe used in the pumping system, and a generator driven by rotating a water turbine with water guided to a pipe having a head difference.

　特許文献１において、地盤の改良工法が提案されている。
　この工法は、ＳＷＰ（スーパーウェルポイント）を用いて飽和地下水を負圧伝播で揚水することで、主に目的のエリアのみ集中してスポット的に水位低下が望め不飽和ゾーンを作り出す。その後、ＳＷＰの真空ポンプや、ボルテックスポンプを用いて、不飽和ゾーンの範囲で真空気化を促進して水分の除去やＶＯＣｓ（揮発性有機化合物）、油分など気化性のものを地中から除去し、地盤改良や土壌浄化を進める。
　以上、従来の地盤改良工法の基本は、地下水を真空吸引で強制排水し、不飽和ゾーンを形成して真空気化を促し、脱水及び乾燥を促進させる工法である。 In patent document 1, the improvement method of the ground is proposed.
In this construction method, the saturated groundwater is pumped up by negative pressure propagation using SWP (Super Well Point), so that only the target area is concentrated and the water level can be lowered spotwise to create an unsaturated zone. After that, use a SWP vacuum pump or vortex pump to accelerate vacuum vaporization in the range of the unsaturated zone to remove moisture, VOCs (volatile organic compounds), oily components such as oil, etc. from the ground. Promote ground improvement and soil purification.
As described above, the basis of the conventional ground improvement method is a method of forcibly draining groundwater by vacuum suction, forming an unsaturated zone, promoting vacuum vaporization, and promoting dehydration and drying.

　ところで、井戸及びＳＷＰ工法等での揚水において、湧水量が多く、ポンプ能力が不足の場合、井戸の増設を必要とするが、井戸の揚水量は、揚水ポンプの出力（能力）とその揚程により決まっており、井戸の増設工事の費用がコストアップとなっていた。

The pumping capacity of the well depends on the output (capacity) of the pump and its head. As a result, the cost of expanding wells was increasing.
And even if it tried to replace a big pumping pump in order to improve a pump capability, there existed a problem which a well diameter could not be inserted small.

　そして、その揚水には、揚水ポンプ６から５ｍ程度の高さにおいて、コンプレッサー８により圧縮エアー供給管７に圧送された圧縮エアーがノズル部７ａから斜め上方に向けて吹き出されて、吸管（すいかん）現象が発生する。その吸管現象によって、揚水管５内の揚水にエアーリフトが作用し、そのエアーリフト併用揚水による吐出し量Ｑ２が、例えば５ｔ／ｍｉｎとなって、揚程５０ｍの地上まで揚水できて、排水と同時に排気することができる。 In the pumping system having the above-described configuration, as shown by an arrow, the groundwater sucked up by the pumping pump 6 through the screen 3 and the water suction hole 1a is pumped into the pumping pipe 5 from the lower end at the lower end of the well 1. The The normal discharge amount Q1 of the pump 6 is, for example, 1 t / min.
In the pumping, the compressed air pumped to the compressed air supply pipe 7 by the compressor 8 is blown obliquely upward from the nozzle portion 7a at a height of about 5 m from the pump 6 and sucked in the suction pipe ) The phenomenon occurs. Due to the suction pipe phenomenon, an air lift acts on the pumping water in the pumping pipe 5, and the discharge amount Q2 by pumping using the air lift is, for example, 5 t / min. Can be exhausted.
　以上の揚水システムによれば、揚水ポンプ６から地上までの揚程５０ｍ、揚水ポンプ６から揚水管５における圧縮エアー供給管７の接続部までの高さ５ｍの場合、揚水ポンプ６の通常吐出し量１ｔ／ｍｉｎに対し、圧縮エアー供給管７のエアーリフト併用揚水による吐出し量５ｔ／ｍｉｎと５倍の能力アップを達成することができる。 According to the above pumping system, when the head is 50 m from the pump 6 to the ground and the height from the pump 6 to the connection of the compressed air supply pipe 7 in the pump 5 is a normal discharge amount of the pump 6. Compared to 1 t / min, the discharge rate of the compressed air supply pipe 7 by pumping with the air lift is 5 t / min, which is 5 times higher.
　以上のとおり、本発明の揚水システムを使用すると、ＳＷＰ等で、真空ポンプを使用しなくても、ある程度の真空は保持できて、真空吸引が可能となる。
　すなわち、井戸１の天端を、ＳＷＰのように、密閉型の上蓋２に加工することで、ＳＷＰ仕様となり、真空吸引が可能となる。
　また、大深度であるため、ＳＷＰのように、セパレートスクリーンのような二重管でなくても、負圧伝播での揚水が可能となる。 As described above, when the pumping system of the present invention is used, a certain degree of vacuum can be maintained with SWP or the like without using a vacuum pump, and vacuum suction is possible.
That is, by processing the top end of the well 1 into a sealed upper lid 2 like SWP, it becomes SWP specification and vacuum suction becomes possible.
Moreover, since it is a deep depth, even if it is not a double pipe like a separate screen like SWP, the pumping by negative pressure propagation is attained.
　例えばコンプレッサー圧Ｐ＝８ｋｇ／ｃｍ２のコンプレッサー８を使用すると、揚水ポンプ６と圧縮エアー供給管７を用いたエアーリフト併用揚水による揚程を、揚水ポンプ６のみの場合よりも約８０ｍ程度深く設置することができる。
　例えば揚水ポンプ６のポンプ能力が揚程Ｈ＝５ｍ位の所の揚水量及び揚水速度を、吸管現象によるエアーリフト併用揚水により格段にアップすることができる。
　すなわち、揚水ポンプ６のレベルより５ｍ位高い所でエアーリフトを行うことで、揚水ポンプ６の吸水口で負圧が生じ、吸管現象にて真空吸引することができる。 For example, if the compressor 8 with a compressor pressure P = 8 kg / cm 2 is used, the head by pumping with the air lift using the pump 6 and the compressed air supply pipe 7 is set about 80 m deeper than the case of the pump 6 alone. be able to.
For example, the pumping capacity and pumping speed when the pumping capacity of the pumping pump 6 is about H = 5 m can be significantly increased by pumping with an air lift due to a suction pipe phenomenon.
That is, by performing an air lift at a place about 5 m higher than the level of the pump 6, a negative pressure is generated at the suction port of the pump 6, and vacuum suction can be performed by a suction pipe phenomenon.

Next, FIG. 2 shows a configuration of an embodiment to which the pumping system of the present invention is applied. As in the principle explanation described above, 1 is a well (steel pipe), 2 is an upper lid, 3 is a screen, and 5 is a pumping pipe. , 6 is a pump, 7 is a compressed air supply pipe, 4 is a vacuum facility, 9 is an observation pipe, 10 is a filter material (marble gravel), 31 and 32 are auxiliary screens, and 33 is a screen connection band.
　図示のように、井戸１、上蓋２、スクリーン３、揚水管５、揚水ポンプ６及び圧縮エアー供給管７に加えて、地上に真空設備４が設置されて、井戸１の外側に沿って観測管９が埋設されており、井戸１の周囲には、５～１０ｍｍ程度の玉砂利によるフィルター材１０が埋設されている。
　なお、図示例では、井戸１の上蓋２から揚水ポンプ６の電源用の動力線２１が導出され、井戸１の下端部のスクリーン３から上の外周に下方から補助スクリーン３１・３２が装着されている。スクリーン３と補助スクリーン３１の間がスクリーン接続バンド３３で接続されるとともに、補助スクリーン３１・３２間がスクリーン接続バンド３３で接続されている。 As shown in the figure, in addition to the well 1, the upper lid 2, the screen 3, the pumping pipe 5, the pumping pump 6 and the compressed air supply pipe 7, a vacuum facility 4 is installed on the ground, and an observation tube is formed along the outside of the well 1. 9 is buried, and around the well 1, a filter material 10 made of gravel of about 5 to 10 mm is buried.
In the illustrated example, the power line 21 for the power source of the pumping pump 6 is led out from the upper lid 2 of the well 1, and the auxiliary screens 31 and 32 are attached to the outer periphery above the screen 3 at the lower end of the well 1 from below. Yes. The screen 3 and the auxiliary screen 31 are connected by a screen connection band 33, and the auxiliary screens 31 and 32 are connected by a screen connection band 33.
　地上に設置された真空設備４は、真空ポンプ４１と冷却水槽（ノッチタンク）４５とからなり、揚水管５の上端部に排水管２２がバルブ２３を介して接続されており、排水管２２は真空ポンプ４１に接続されている。
　そして、上蓋２に接続した吸気管２４が真空ポンプ４１に接続されて、真空ポンプ４１から導出された排水ホース４２が冷却水槽４５の内部に開放されている。
　また、真空ポンプ４１から導出された排気ホース４３の延長端部には、冷却水槽４５の内方上部において、排気消音装置４４が接続されている。 The vacuum equipment 4 installed on the ground includes a vacuum pump 41 and a cooling water tank (notch tank) 45, and a drain pipe 22 is connected to the upper end of the pumping pipe 5 via a valve 23. The vacuum pump 41 is connected.
The intake pipe 24 connected to the upper lid 2 is connected to the vacuum pump 41, and the drain hose 42 led out from the vacuum pump 41 is opened inside the cooling water tank 45.
Further, an exhaust silencer 44 is connected to an extended end portion of the exhaust hose 43 led out from the vacuum pump 41 at an inner upper portion of the cooling water tank 45.
　以上の揚水システムにおいて、井戸１の内部に通した圧縮エアー供給管７の下端部を上方に折り返すように屈曲させたノズル部７ａが、揚水ポンプ６の揚程位置（通常吐出し量が、例えば７ｔ／ｍｉｎの場合、揚水ポンプ６から１０ｍ程度の高さ）で、揚水管５の外周部に接続されている。
　また、井戸１の内部で揚水管５の周囲は、上蓋２で密閉されて、上蓋２に吸気管２４を介して接続した真空ポンプ４１の真空吸引により負圧状態に維持されている。
　そして、揚水管５内の揚水は、排水管２２を介して真空ポンプ４１に真空吸引されてから、排水ホース４２を介して冷却水槽４５に排水されると同時に、排気ホース４３を経て、冷却水槽４５の内方上部において、排気消音装置４４から排気される。
　これにより、揚水ポンプ６の周辺部の水と空気が吸い上げられて真空度が高められる。 In the above pumping system, the nozzle portion 7a bent so that the lower end portion of the compressed air supply pipe 7 passed through the inside of the well 1 is folded upward is the head position of the pump 6 (the normal discharge amount is, for example, 7t). In the case of / min, the pumping pump 6 is connected to the outer peripheral portion of the pumping pipe 5 at a height of about 10 m.
Further, the periphery of the pumping pipe 5 inside the well 1 is hermetically sealed with the upper lid 2 and maintained in a negative pressure state by vacuum suction of a vacuum pump 41 connected to the upper lid 2 via an intake pipe 24.
Then, the pumped water in the pumping pipe 5 is vacuum sucked by the vacuum pump 41 through the drain pipe 22, and then drained into the cooling water tank 45 through the drain hose 42, and at the same time through the exhaust hose 43, the cooling water tank Exhaust air is exhausted from the exhaust silencer 44 at the inner upper portion of 45.
Thereby, the water and air of the peripheral part of the pump 6 are sucked up, and a vacuum degree is raised.
　図３は図２の圧縮エアー供給部分の拡大断面を示すもので、図示のように、揚水ポンプ６による揚水管５内の揚水には、コンプレッサー８（図１参照）により圧縮エアー供給管７に圧送された圧縮エアーがノズル部７ａから斜め上方に向けて吹き出されて、吸管現象が発生する。その吸管現象によって、揚水管５内にエアーリフトが作用し、そのエアーリフト併用揚水による吐出し量Ｑ２及び揚程を増大して、地上まで揚水することができる。 FIG. 3 shows an enlarged cross section of the compressed air supply portion of FIG. 2. As shown in the drawing, the pumped water in the pumping pipe 5 by the pumping pump 6 is supplied to the compressed air supply pipe 7 by a compressor 8 (see FIG. 1). The compressed compressed air is blown obliquely upward from the nozzle portion 7a, and a suction pipe phenomenon occurs. By the suction pipe phenomenon, an air lift acts in the pumping pipe 5, and the discharge amount Q2 and the head by pumping with the air lift can be increased to pump the water to the ground.
　このように、揚水管５内に吹き管状となるように圧縮エアー供給管７を取り付けることで、エアーリフトを併用できることによって、結果として、揚水ポンプ６の吐出し能力が上昇する。 Thus, by attaching the compressed air supply pipe 7 so as to form a blown tube in the pumping pipe 5, the air lift can be used together, and as a result, the discharge capacity of the pumping pump 6 is increased.
　図４は図２の圧縮エアー供給管７１を備える揚水管５１を示すもので、図示のように、揚水管５１の外周部には、圧縮エアー供給管７１が接続されている。
　すなわち、揚水管５１は、前述した長尺の揚水管５の一部をなす分割体で、その両端部にジョイント用フランジ５２を備えている。
　圧縮エアー供給管７１は、前述した長尺の圧縮エアー供給管７の下端部をなす分割体で、折り返し状屈曲部７ｂから延びるノズル部７ａが形成されている。
　そのノズル部７ａが、揚水管５１の外周部に接続されている。折り返し状屈曲部７ｂのノズル部７ａと反対側端部に、井戸１の内部に通す長尺の圧縮エアー供給管７が接続される。 FIG. 4 shows a pumping pipe 51 provided with the compressed air supply pipe 71 of FIG. 2, and a compressed air supply pipe 71 is connected to the outer peripheral portion of the pumping pipe 51 as shown in the figure.
That is, the pumping pipe 51 is a divided body that forms a part of the long pumping pipe 5 described above, and is provided with joint flanges 52 at both ends thereof.
The compressed air supply pipe 71 is a divided body that forms the lower end of the long compressed air supply pipe 7 described above, and is formed with a nozzle portion 7a extending from the folded-back bent portion 7b.
The nozzle portion 7 a is connected to the outer peripheral portion of the pumped-up pipe 51. A long compressed air supply pipe 7 passing through the inside of the well 1 is connected to the end of the folded bent portion 7b opposite to the nozzle portion 7a.
　図５は揚程－吐出し量の特性を示すもので、図示のように、例えば揚水ポンプ６のみによる揚水特性Ａに対し、圧縮エアー供給管７を用いたエアーリフト併用揚水による、吐出し量及び揚程を増大した揚水特性Ｂが得られる。
　すなわち、揚水特性Ａの揚水ポンプ６の能力で対比した場合、揚程Ｈ＝３０ｍで吐出し量Ｑ＝２．０ｔ／ｍｉｎの揚水ポンプ６において、揚水ポンプ６から高さ５．０ｍの所で圧縮エアー供給管７を用いたエアーリフトを併用すると、揚水特性Ｂで示したように、吐出し量Ｑ＝６．３ｔ／ｍｉｎに増大することができる。 FIG. 5 shows the characteristics of the lift-discharge amount. As shown in the figure, for example, the discharge amount and the discharge amount by pumping combined with an air lift using the compressed air supply pipe 7 with respect to the pumping characteristic A by the pump 6 alone. A pumping characteristic B with an increased head is obtained.
That is, when compared with the capacity of the pump 6 having the pumping characteristic A, the pump at the height of 5.0 m from the pump 6 is compressed in the pump 6 having a head H = 30 m and a discharge amount Q = 2.0 t / min. When an air lift using the air supply pipe 7 is used in combination, the discharge amount Q can be increased to 6.3 t / min as shown by the pumping characteristic B.
　以上、実施形態の揚水システムによれば、下端に揚水ポンプ６を備える揚水管５の外周に接続されて、当該揚水管５内に対し斜め上方に圧縮エアーを供給する圧縮エアー供給管７と、その圧縮エアー供給管７に接続されるコンプレッサー８と、を備えて、吸管現象によるエアーリフトを併用しているため、揚水量及び揚水速度を格段に向上して、真空ポンプを用いなくても、揚程をアップして、揚水量をアップすることができる。 As described above, according to the pumping system of the embodiment, the compressed air supply pipe 7 connected to the outer periphery of the pumping pipe 5 provided with the pumping pump 6 at the lower end and supplying the compressed air obliquely upward with respect to the pumping pipe 5; The compressor 8 connected to the compressed air supply pipe 7 is used together with an air lift by suction pipe phenomenon, so that the amount of pumping and the pumping speed can be greatly improved without using a vacuum pump.

　次に、図６は本発明の揚水システムを適用した実施形態２の構成を示すもので、図２と同様、１は井戸（鋼管）、１ａは吸水孔、２は上蓋、３はスクリーン、５は揚水管、６は揚水ポンプ、７は圧縮エアー供給管、７ａはノズル部、９は観測管、１０はフィルター材（玉砂利）、３１・３２は補助スクリーン、３３はスクリーン接続バンドである。 (Embodiment 2)
Next, FIG. 6 shows the structure of Embodiment 2 to which the pumping system of the present invention is applied. As in FIG. 2, 1 is a well (steel pipe), 1a is a water absorption hole, 2 is an upper lid, 3 is a screen, 5 Is a pumping pump, 6 is a pumping pump, 7 is a compressed air supply pipe, 7a is a nozzle section, 9 is an observation pipe, 10 is a filter material (marvel), 31 and 32 are auxiliary screens, and 33 is a screen connection band.
　実施形態２は温泉揚水システムで、図示のように、井戸１、上蓋２、スクリーン３、揚水管５、揚水ポンプ６及び圧縮エアー供給管７により構成されている。
　すなわち、鋼管による井戸１において、図示のように、揚水ポンプ６により揚水管５内に揚水される温泉（源泉）には、コンプレッサー８（図１参照）により圧縮エアー供給管７に圧送された圧縮エアーがノズル部７ａから斜め上方に向けて吹き出されて、吸管現象が発生する。その吸管現象によって、揚水管５内にエアーリフトが作用し、そのエアーリフト併用揚水による吐出し量Ｑ２及び揚程を増大して、温泉を地上まで揚水することができる。 Embodiment 2 is a hot spring pumping system, which is composed of a well 1, an upper lid 2, a screen 3, a pumping pipe 5, a pumping pump 6, and a compressed air supply pipe 7, as shown in the figure.
That is, in the well 1 made of steel pipe, as shown in the drawing, the hot spring (source spring) pumped into the pumping pipe 5 by the pumping pump 6 is compressed by the compressor 8 (see FIG. 1) and pumped to the compressed air supply pipe 7. Air is blown obliquely upward from the nozzle portion 7a, and a suction tube phenomenon occurs. Due to the suction pipe phenomenon, an air lift acts in the pumping pipe 5, and the discharge amount Q <b> 2 and the pumping height by the pumping combined with the air lift can be increased to pump the hot spring to the ground.
　このように、揚水管５内に吹き管状となるように圧縮エアー供給管７を取り付けることで、エアーリフトを併用できることによって、結果として、揚水ポンプ６の温泉の吐出し能力が上昇する。
　したがって、温泉の揚水湯量及び揚水速度を格段に上げることができ、これにより、揚水過程での温度損失を極力抑えて、地上に揚水した温泉の温度を上げることができる。 In this way, by attaching the compressed air supply pipe 7 so as to be a blown pipe in the pumping pipe 5, the air lift can be used together, and as a result, the hot spring discharge capacity of the pumping pump 6 is increased.
Therefore, the amount of hot water and the pumping speed of the hot spring can be significantly increased, and thereby the temperature loss during the pumping process can be suppressed as much as possible, and the temperature of the hot spring pumped to the ground can be increased.
　以上、実施形態２の温泉揚水システムによれば、下端に揚水ポンプ６を備える揚水管５内に対し、圧縮エアー供給管７により斜め上方に圧縮エアーを供給する吸管現象によるエアーリフトを併用しているため、揚水量及び揚水速度を格段に向上して、真空ポンプを用いなくても、温泉の揚程をアップして、温泉の揚水量をアップすることができる。 As mentioned above, according to the hot spring pumping system of Embodiment 2, the air lift by the suction pipe phenomenon which supplies compressed air diagonally upward with the compressed air supply pipe 7 is used together with the pumping pipe 5 having the pump 6 at the lower end. Therefore, the pumping amount and the pumping speed can be remarkably improved, and the pumping amount of the hot spring can be increased by increasing the hot spring head without using a vacuum pump.
　また、温泉揚水システムにより温泉をリニューアルした場合にも、吸管現象によるエアーリフト併用によって、温泉の揚水湯量及び揚水速度を格段に上げて、揚水過程での温度損失を極力抑えて、地上に揚水した温泉の温度を以前より上げることができる。 In addition, even when hot springs were renewed with the hot spring pumping system, the amount of hot water and the pumping speed of the hot springs were dramatically increased by using an air lift due to the suction pipe phenomenon, and the temperature loss during the pumping process was suppressed as much as possible to pump the water on the ground. You can raise the temperature of the hot springs.

A water discharge pipe 104 that is connected to the outer periphery of the water discharge pipe 104, a compressed air supply pipe 105 that supplies compressed air obliquely with respect to the water discharge direction into the water discharge pipe 104, and a compressed air supply pipe 105. Compressor 106.
　このように、水車１０３からの放水管１０４内の水には、コンプレッサー１０６により圧縮エアー供給管１０５に圧送された圧縮エアーがノズル部１０５ａから斜め下方に向けて吹き出されて、吸管現象が発生する。その吸管現象によって、放水管１０４内にエアーリフトが作用し、そのエアーリフト併用放水によって、水圧管路１０２内から水車１０３へ流れ込む水の速度及び水量を増大して、発電機による発電効率をアップすることができる。 As described above, the water in the water discharge pipe 104 from the water wheel 103 is blown obliquely downward from the nozzle portion 105a by the compressed air that is pressure-fed to the compressed air supply pipe 105 by the compressor 106, and a suction pipe phenomenon occurs. . The suction pipe phenomenon causes an air lift to act in the water discharge pipe 104, and the water discharge combined with the air lift increases the speed and amount of water flowing from the hydraulic pipe line 102 into the water turbine 103, thereby improving the power generation efficiency by the generator. can do.
　以上、実施形態３の水力発電システムによれば、下水車１０３からの放水管１０４内に対し、圧縮エアー供給管１０５により斜め下方に圧縮エアーを供給する吸管現象によるエアーリフトを併用しているため、水圧管路１０２内から水車１０３へ流れ込む水の速度及び水量を増大して、発電効率をアップすることができる。 As described above, according to the hydroelectric power generation system of the third embodiment, the air lift by the suction pipe phenomenon that supplies the compressed air obliquely downward by the compressed air supply pipe 105 is used together with the discharge pipe 104 from the sewer wheel 103. The speed and amount of water flowing into the water wheel 103 from the water pressure line 102 can be increased to increase the power generation efficiency.
（実施形態４）
　実施形態３では、水力発電システムに適用したが、単純な送水システムであってもよい。
　すなわち、実施形態４は、図示しないが、送水ポンプ等の送水装置に接続される送水管を備える送水システムにおいて、その送水管の外周に接続されて、当該送水管内に送水方向に対し斜めに圧縮エアーを供給する圧縮エアー供給管と、その圧縮エアー供給管に接続されるコンプレッサーと、を備える構成とする。 (Embodiment 4)
In Embodiment 3, although applied to the hydroelectric power generation system, a simple water supply system may be used.
That is, although not shown, Embodiment 4 is connected to the outer periphery of the water supply pipe in a water supply system including a water supply pipe connected to a water supply device such as a water supply pump, and is compressed obliquely with respect to the water supply direction in the water supply pipe. It is set as the structure provided with the compressed air supply pipe | tube which supplies air, and the compressor connected to the compressed air supply pipe | tube.
　このように、送水管内に送水方向に対し斜めに圧縮エアーを供給することで、吸管現象によるエアーリフト併用によって、送水量及び送水速度を格段に向上することができる。 Thus, by supplying compressed air obliquely in the water supply direction into the water supply pipe, the water supply amount and the water supply speed can be remarkably improved by the combined use of the air lift due to the suction pipe phenomenon.
