Abstract

A problem associated with conventional seawater desalination devices is that the devices are heavy and large and therefore can be installed only in specific locations. A water purification device has: a pretreatment filter (5) for removing coarse foreign substances from water; an RO membrane filter (7) for removing impurities from the water having been filtered by the pretreatment filter; a force pump (6) driven by a DC motor and delivering water to the pretreatment filter (5); a pressurizing pump (8) driven by a DC motor and delivering water to the RO membrane filter (7); an input generator (2) for generating electric power for driving the force pump (6) and the pressurizing pump (8); and a case (12) for housing the pretreatment filter (5), the RO membrane filter (7), the force pump (6), and the pressurizing pump (8). Electric power is supplied to the force pump (6) and the pressurized pump (8) through a connectable and disconnectable electrical cable (15) from the input generator (2) located outside the housing case (12).

Description

水浄化装置Water purification equipment
　本発明は、不純物が混入している水を浄化する水浄化装置に関する。 The present invention relates to a water purification apparatus that purifies water in which impurities are mixed.
地球上の水分のうちの多くが海水であり、淡水は０．７～１０％しかないと言われている。そして、２０５０年までには世界の人口は、現在より３０億人増加して９０億人になると予測され、今後ますます水不足は深刻さを増すことが見込まれている。 It is said that most of the water on the earth is seawater, and fresh water is only 0.7 to 10%. By 2050, the world's population is expected to increase by 3 billion from the present to 9 billion, and water shortages are expected to become increasingly serious in the future.
　この水不足を補うために、従来から海水から淡水を得る海水淡水化装置が知られている。この種の海水淡水化装置として、前処理装置、高圧ポンプ、逆浸透膜モジュール等を備えるものがあった。具体的には、海水淡水化装置に供給される海水は、前処理装置で固形性・溶解性物質を除去され前処理水となり、その前処理水は、高圧ポンプで加圧され、逆浸透膜を有する逆浸透膜モジュールに流入し、透過水と濃縮水に分離されるものがあった。このような従来の海水淡水化装置では、淡水の生産時に大きなエネルギーを発生させることができる高圧ポンプが用いられているので、装置自体が大重量かつ大型化していた。このように、海水淡水化装置が大重量かつ大型であるので、海水淡水化装置が設置されている施設は都市近辺に集中し、水不足が深刻な離島、僻地には設置されていないのが実情である。これについては、ヒ素やダイオキシンが混入している井戸水、河川水、湖水、溜池水などの水浄化装置についても同様である。 In order to make up for this water shortage, seawater desalination apparatuses that obtain fresh water from seawater have been known. Some seawater desalination apparatuses of this type include a pretreatment apparatus, a high-pressure pump, a reverse osmosis membrane module, and the like. Specifically, seawater supplied to the seawater desalination apparatus is pretreated water from which solid and soluble substances are removed by the pretreatment apparatus, and the pretreated water is pressurized by a high-pressure pump, and is supplied with a reverse osmosis membrane. In some cases, a reverse osmosis membrane module having a water content is separated into permeated water and concentrated water. In such a conventional seawater desalination apparatus, a high-pressure pump capable of generating large energy during the production of fresh water is used, so that the apparatus itself is heavy and large. As described above, since the seawater desalination equipment is heavy and large, the facilities where the seawater desalination equipment is installed are concentrated in the vicinity of the city and are not installed on remote islands or remote areas where water shortages are serious. It is. The same applies to water purification devices such as well water, river water, lake water, and pond water in which arsenic and dioxins are mixed.

　世界の離島、僻地には安全な水が不足している地域が多くある。このような地域では、衛生状態の悪化により、死亡率が高くなっているのが現状である。たとえば、東アフリカのウガンダでは、衛生状態の悪化による５歳未満の乳幼児死亡率が１１．５％と非常に高い。 There are many areas on the remote islands and remote areas of the world that lack safe water. In such areas, the mortality rate is increasing due to the deterioration of hygiene. For example, in Uganda, East Africa, the infant mortality rate under 5 years of age due to poor hygiene is very high at 11.5%.
　しかしながら、従来の海水淡水化装置では、装置自体が大重量かつ大型化しているため、都市近辺の特定の施設に海水淡水化装置が設置され、その施設外に持ち出して海水淡水化装置を使用することができなかった。また、従来の海水淡水化装置では高圧ポンプなどを駆動させる電力を必要とするため、電気設備が整っていない地域で使用することができなかった。 However, in the conventional seawater desalination apparatus, since the apparatus itself is heavy and large-sized, the seawater desalination apparatus is installed in a specific facility near the city, and the seawater desalination apparatus is used outside the facility. I couldn't. Moreover, since the conventional seawater desalination apparatus requires the electric power which drives a high pressure pump etc., it could not be used in the area where electric equipment is not prepared.
　本発明は上記問題点に鑑みてなされたもので、電気設備が整っていない地域でも使用することができるとともに、小形軽量で持ち運び可能な水浄化装置を提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a small, lightweight and portable water purification apparatus that can be used in areas where electric facilities are not provided.
　上記課題を解決し上記目的を達成するために、本発明のうち第１の態様に係るものは、不純物が混入している水を浄化する水浄化装置であって、不純物が混入している水から粗ゴミを除去する前処理フィルタと、前処理フィルタから流送された水から不純物を除去するＲＯ膜フィルタと、ＤＣモータにより駆動され、不純物が混入している水を前処理フィルタに搬送する送圧ポンプと、ＤＣモータにより駆動され、前処理フィルタから流送された水をＲＯ膜フィルタに搬送する加圧ポンプと、送圧ポンプと加圧ポンプを駆動させるための電力を人力より発生させる人力発電機と、前処理フィルタ、ＲＯ膜フィルタ、送圧ポンプ、および加圧ポンプを収納する収納ケースと、を有し、収納ケース外の人力発電機から着脱可能の電気ケーブルを介して、送圧ポンプおよび加圧ポンプに電力が供給されることを特徴とするものである。 In order to solve the above problems and achieve the above object, the first aspect of the present invention is a water purification apparatus for purifying water in which impurities are mixed, and water in which impurities are mixed A pretreatment filter that removes coarse dust from the RO, a RO membrane filter that removes impurities from the water flown from the pretreatment filter, and a DC motor that drives the water contaminated with impurities to the pretreatment filter A pressure pump, driven by a DC motor, and a pressure pump that transports water fed from the pretreatment filter to the RO membrane filter, and electric power for driving the pressure pump and the pressure pump are generated by human power. A power generator and a storage case for storing the pretreatment filter, the RO membrane filter, the pressure pump, and the pressure pump; and an electric cable that is detachable from the power generator outside the storage case.

　近年の水浄化装置では、生成水量と費用対効果の面からＲＯ膜フィルタが広く用いられている。このＲＯ膜フィルタは０．１ｎｍと細かい膜であるため、ＲＯ膜フィルタで塩分、ヒ素やダイオキシンなどの不純物を除去するためには４．５ＭＰａ（４５気圧）以上の大きな圧力をかける必要がある。本発明によれば、加圧ポンプがＤＣモータにより駆動されるので、不純物が混入している水をＲＯ膜フィルタに高効率に通水することができ、４．５ＭＰａ以上の圧力を確保して水から塩分などの不純物を除去することができる。また、送圧ポンプおよび加圧ポンプをＤＣモータにより駆動させることにより、送圧ポンプおよび加圧ポンプを小型・軽量化ができ、その小型、軽量化された送圧ポンプおよび加圧ポンプ、前処理フィルタ、ＲＯ膜フィルタを人力発電機とは別に収納ケースに収納することにより、小型、軽量化された水浄化装置の主要部品を収納ケースに入れて移動させることが可能となる。これにより、水浄化装置を奥深い僻地などにも容易に移動させることができる。
　また、送圧ポンプと加圧ポンプを駆動させるための電力を人力より発生させる人力発電機を用いているので、発展途上国のような電気設備が整っていない地域でも不純物が混入している水から安全な飲料水を得ることができる。このように、本発明の水浄化装置を用いることにより、アフリカ地域などの水浄化システムが整っていない場所などに水浄化装置を移動させることができるとともに、移動させた地域が電気設備の整っていない地域でも、水浄化装置を用いて不純物が混入している水から安全な飲料水を生成することができる。これにより、乳幼児等の死亡率を低くすることができる。 In recent water purification apparatuses, RO membrane filters are widely used from the viewpoint of the amount of produced water and cost effectiveness. Since this RO membrane filter is a fine membrane of 0.1 nm, it is necessary to apply a large pressure of 4.5 MPa (45 atm) or more in order to remove impurities such as salt, arsenic and dioxin with the RO membrane filter. According to the present invention, since the pressure pump is driven by the DC motor, water in which impurities are mixed can be passed through the RO membrane filter with high efficiency, and a pressure of 4.5 MPa or more can be secured. Impurities such as salt can be removed from water. In addition, by driving the pressure pump and pressure pump with a DC motor, the pressure pump and pressure pump can be reduced in size and weight. By storing the filter and the RO membrane filter in the storage case separately from the human power generator, it is possible to move the main parts of the water purification device that is reduced in size and weight into the storage case. Thereby, a water purification apparatus can be easily moved also to a deep remote place.

Thus, since the pressurizing pump 8 is driven with high efficiency by the DC motor, it is possible to ensure the pressure of 4.5 MPa or more and transport water to the RO membrane filter 7.
　オゾン生成機９は、ＲＯ膜フィルタ７から流送された濾過水に混合させるオゾンを生成させる機械である。具体的には、オゾン生成機９は、放電電極に数ｋＷの高電圧を印加して無声放電を生起し、原料気体（酸素又は酸素を含む空気）の酸素を電離させてオゾンを生成している。このオゾン生成機９により生成されたオゾンをＲＯ膜フィルタ７から流送された濾過水にエジェクターで気液混合することにより、オゾン水を生成することができる。 The ozone generator 9 is a machine that generates ozone to be mixed with the filtered water fed from the RO membrane filter 7. Specifically, the ozone generator 9 applies a high voltage of several kW to the discharge electrode to cause silent discharge, ionizes oxygen in the source gas (oxygen or air containing oxygen), and generates ozone. Yes. Ozone water can be generated by gas-liquid mixing the ozone generated by the ozone generator 9 with the filtered water fed from the RO membrane filter 7 using an ejector.

In addition, a metal lattice made of a lightweight material such as aluminum for placing the battery 3 and the ozone generator 9 is provided inside the storage case 12a.
　オゾン水排出口１０は、オゾン生成機９により生成されたオゾンとＲＯ膜フィルタ７から流送された濾過水とを混合して生成されたオゾン水の取出口である。図２では、収納ケース１２ａ外に示されているが、収納ケース１２ａの壁面に設けるようにしてもよい。そして、このオゾン水排出口１０にホースなどを繋げてオゾン水が排出される。 The ozone water discharge port 10 is an outlet for ozone water generated by mixing ozone generated by the ozone generator 9 and filtered water fed from the RO membrane filter 7. Although shown in FIG. 2 outside the storage case 12a, it may be provided on the wall surface of the storage case 12a. And ozone water is discharged by connecting a hose or the like to the ozone water discharge port 10.
　濾過水排出口１１は、ＲＯ膜フィルタ７とオゾン生成機９の流路内のＲＯ膜フィルタ７により不純物が除去された濾過水の取出口である。濾過水排出口１１についても、オゾン水排出口１０と同様、収納ケース１２ａ外に示されているが、収納ケース１２ａの壁面に設けるようにしてもよい。そして、この濾過水排出口１１にホースなどを繋げて濾過水（飲料水）が排出される。 The filtered water discharge port 11 is an outlet for filtered water from which impurities have been removed by the RO membrane filter 7 and the RO membrane filter 7 in the flow path of the ozone generator 9. The filtered water discharge port 11 is also shown outside the storage case 12a as with the ozone water discharge port 10, but it may be provided on the wall surface of the storage case 12a. And filtered water (drinking water) is discharged by connecting a hose etc. to this filtered water discharge port 11.

The size of the loading platform of the handcart 13 is formed larger than the size of the bottom surface of the storage case 12a, and four wheels are provided on the bottom surface of the cart.
　次に、水浄化装置１ａを運搬して移動させる方法について、図３を参照にしながら説明する。ここで、図３は本発明の第１実施形態における水浄化装置の運搬方法を示す図である。 Next, a method for transporting and moving the water purification apparatus 1a will be described with reference to FIG. Here, FIG. 3 is a figure which shows the conveyance method of the water purification apparatus in 1st Embodiment of this invention.
　水浄化装置１ａを運搬して移動させる前に、収納ケース１２ａと連結配管１４ａにより連結されている不純物混入水タンク４　および収納ケース１２ａと電気ケーブル１５により連結されている人力発電機２を、それぞれ収納ケース１２ａから切り離す。具体的には、収納ケース１２ａの側壁面において、収納ケース１２ａ内の連結配管１４ａと収納ケース１２ａ外の連結配管１４ａが切り離される。ここで、収納ケース１２ａ内の連結配管１４ａと収納ケース１２ａ外の連結配管１４ａは、収納ケース１２ａの側壁面において着脱可能に結合されている。また同様に、収納ケース１２ａの側壁面において、収納ケース１２ａ内の電気ケーブル１５と収納ケース１２ａ外の電気ケーブル１５が切り離される。ここで、収納ケース１２ａ内の電気ケーブル１５と収納ケース１２ａ外の電気ケーブル１５についても、収納ケース１２ａの側壁面において着脱可能に結合されている。この連結配管１４ａの結合部では不純物が混入している水が漏れないように強固に結合され、また電気ケーブル１５の結合部では結合が緩まないように強固に結合されている。そして、連結配管１４ａおよび電気ケーブル１５の切り離しは、それぞれの結合部の周辺を収納ケース１２ａの方向に押圧することにより行われる。このようにすることにより、収納ケース１２ａ、不純物混入水タンク４、および人力発電機２がそれぞれ別体として構成される。なお、不純物混入水タンク４と連結配管１４ａ、および人力発電機２と電気ケーブル１５についても、上記の収納ケース１２ａの側壁面の切離方法と同様の方法により切り離すことができる。 Before transporting and moving the water purification device 1a, the impurity-mixed water tank 4 connected by the storage case 12a and the connecting pipe 14a and the human power generator 2 connected by the storage case 12a and the electric cable 15 are respectively Separate from the storage case 12a. Specifically, on the side wall surface of the storage case 12a, the connection pipe 14a in the storage case 12a and the connection pipe 14a outside the storage case 12a are separated. Here, the connecting pipe 14a in the storage case 12a and the connecting pipe 14a outside the storage case 12a are detachably coupled on the side wall surface of the storage case 12a. Similarly, on the side wall surface of the storage case 12a, the electrical cable 15 in the storage case 12a and the electrical cable 15 outside the storage case 12a are disconnected. Here, the electrical cable 15 in the storage case 12a and the electrical cable 15 outside the storage case 12a are also detachably coupled on the side wall surface of the storage case 12a. The connecting portion of the connecting pipe 14a is firmly connected so that water mixed with impurities does not leak, and the connecting portion of the electric cable 15 is firmly connected so that the connection is not loosened. Then, the connection pipe 14a and the electric cable 15 are separated by pressing the periphery of each coupling portion in the direction of the storage case 12a. By doing so, the storage case 12a, the impurity-mixed water tank 4, and the human power generator 2 are configured as separate bodies. The impurity-mixed water tank 4 and the connecting pipe 14a, and the manpower generator 2 and the electric cable 15 can also be separated by the same method as the method for separating the side wall surface of the storage case 12a.
　次に、蓄電器３、前処理フィルタ５、ＲＯ膜フィルタ７、送圧ポンプ６、加圧ポンプ８、およびオゾン生成機９が収納されている収納ケース１２ａを手押台車１３の荷台に載置させる。ここで、蓄電器３、前処理フィルタ５、ＲＯ膜フィルタ７、送圧ポンプ６、加圧ポンプ８、およびオゾン生成機９が収納されている収納ケース１２ａは軽量に構成されているので、収納ケース１２ａの手押台車１３の荷台への載置は手動により行うことができる。ここで、不純物混入水タンク４および人力発電機２については、それぞれ別の手押台車に載置させて移動させている。なお、本実施形態では、蓄電器３およびオゾン生成機９についても収納ケース１２ａに収納することとしたが、蓄電器３およびオゾン生成機９は任意の構成であるので、蓄電器３およびオゾン生成機９を設けていない場合は、蓄電器３およびオゾン生成機９は収納ケース１２ａに収納されない。また、本実施形態では。収納ケース１２ａと、不純物混入水タンク４および人力発電機２をそれぞれ別の手押台車に載置させて移動させたが、収納ケース１２ａの上部にアルミニウムなどの軽量材料からできた金属板を被せて、その金属板の上部に不純物混入水タンク４および人力発電機２を載置して移動させるようにしてもよい。また、収納ケース１２ａ、不純物混入水タンク４、および人力発電機２を車や船や飛行機で外国や離島や山奥の僻地などに運び、その外国や離島や山奥の僻地などで手押台車１３に載せ移動させるようにしてもよい。 Next, the storage case 12a in which the battery 3, the pretreatment filter 5, the RO membrane filter 7, the pressure pump 6, the pressure pump 8, and the ozone generator 9 are stored is placed on the loading platform of the handcart 13. . Here, the storage case 12a in which the capacitor 3, the pretreatment filter 5, the RO membrane filter 7, the pressure pump 6, the pressure pump 8, and the ozone generator 9 are stored is configured to be lightweight. Placement of the hand cart 13a on the loading platform 12a can be performed manually. Here, the impurity-mixed water tank 4 and the human power generator 2 are moved by being placed on separate handcarts. In the present embodiment, the storage device 3 and the ozone generator 9 are also stored in the storage case 12a. However, since the storage device 3 and the ozone generator 9 have arbitrary configurations, the storage device 3 and the ozone generator 9 are When not provided, the battery 3 and the ozone generator 9 are not stored in the storage case 12a. In the present embodiment. The storage case 12a, the impurity-contaminated water tank 4 and the manpower generator 2 were moved by placing them on separate handcarts, but the upper part of the storage case 12a was covered with a metal plate made of a lightweight material such as aluminum. Then, the impurity-mixed water tank 4 and the human power generator 2 may be placed and moved on the upper part of the metal plate. Further, the storage case 12a, the impurity-contaminated water tank 4, and the human power generator 2 are transported by car, ship or airplane to a foreign country, a remote island, or a remote mountainous area, and are transferred to the handcart 13 in the foreign country, a remote island, or a remote mountainous area. You may make it carry.
　外国や離島や山奥の僻地などの移動場所に到着した後は、収納ケース１２ａなどを手押台車１３から降ろし、収納ケース１２ａを所定の設置場所に設置し、その収納ケース１２ａに連結配管１４ａにより不純物混入水タンク４を連結させ　また電気ケーブル１５により人力発電機２を連結させる。このようにすることにより、水浄化装置１ａの他の設置場所への移動が完了する。 After arriving at a moving place such as a foreign country, a remote island or a mountainous area, the storage case 12a and the like are lowered from the handcart 13 and the storage case 12a is installed at a predetermined installation location. The storage case 12a is connected to the storage case 12a by a connecting pipe 14a. The impure water tank 4 is connected, and the human power generator 2 is connected by the electric cable 15. By doing in this way, the movement to the other installation place of the water purification apparatus 1a is completed.
　このように、本実施形態の水浄化装置１ａによれば、送圧ポンプ６および加圧ポンプ８にＤＣモータを用いているので、送圧ポンプ６および加圧ポンプ８を小型・軽量化ができる。そして、その小型、軽量化された送圧ポンプ６および加圧ポンプ８、前処理フィルタ５、ＲＯ膜フィルタ７などを人力発電機２とは別に収納ケース１２ａに収納することにより、小型、軽量化された水浄化装置１ａの主要部品を収納ケース１２ａに入れて移動させることが可能となる。これにより、水浄化装置１ａを容易に移動させることができる。 Thus, according to the water purification apparatus 1a of this embodiment, since the DC motor is used for the pressure feed pump 6 and the pressure pump 8, the pressure feed pump 6 and the pressure pump 8 can be reduced in size and weight. . The compact and lightweight pressure pump 6 and pressurizing pump 8, pretreatment filter 5, RO membrane filter 7 and the like are housed in the housing case 12 a separately from the human power generator 2, thereby reducing the size and weight. The main components of the water purification device 1a thus made can be moved in the storage case 12a. Thereby, the water purification apparatus 1a can be moved easily.
　次に、水浄化装置１ａの使用方法について説明する。 Next, a method for using the water purification apparatus 1a will be described.
　まず、不純物混入水タンク４に、塩分が含有した海水や、ヒ素やダイオキシンが含有している井戸水、河川水、湖水、溜池水などの不純物が混入している水を貯留させる。 First, in the impurity-contaminated water tank 4, water containing impurities such as seawater containing salt, well water containing arsenic or dioxin, river water, lake water, pond water, etc. is stored.
　次に、人力発電機２を回転させて電力を発電し、その発電された電力は電気ケーブル１５を介して蓄電器３に蓄電される。なお、蓄電器３に前もって電力が蓄電されている場合は、このタイミングで人力発電機２により電力を発電させる必要はない。このように、本実施形態では、人力発電機２より発生させた電力を蓄電する蓄電器３を用いているので、水浄化装置１ａを使用していないときに人力発電機２より電力を蓄電器３に蓄電させ、その蓄電させた蓄電器３の電力を用いて送圧ポンプ６と加圧ポンプ８を駆動させることができる。これにより、水浄化装置１ａの使用時の負担を軽減させることができる。 Next, the human power generator 2 is rotated to generate electric power, and the generated electric power is stored in the battery 3 through the electric cable 15. In addition, when electric power is previously stored in the capacitor 3, it is not necessary to generate electric power by the human power generator 2 at this timing. Thus, in this embodiment, since the electric storage device 3 that stores the electric power generated from the human power generator 2 is used, the electric power is supplied from the human power generator 2 to the electric storage device 3 when the water purification device 1a is not used. The pressure-feed pump 6 and the pressure pump 8 can be driven using the electric power stored in the stored battery 3. Thereby, the burden at the time of use of the water purification apparatus 1a can be reduced.
　次に、送圧ポンプ６の電源スイッチをＯＮにし、蓄電器３に蓄電された電力により送圧ポンプ６を駆動させる。これにより、送圧ポンプ６の駆動力により、不純物混入水タンク４内の不純物が混入している水は連結配管１４ａを介し前処理フィルタ５に搬送され、前処理フィルタ５により不純物が混入している水から粗ゴミを取ることができる。このように、ＲＯ膜フィルタ７の前に前処理フィルタ５を用いて粗ゴミを取ることにより、ＲＯ膜フィルタ７の寿命を長くすることができる。なお、送圧ポンプ６の電源スイッチをＯＮするタイミングについては上記のタイミングである必要はなく、送圧ポンプ６により不純物混入水タンク４内の不純物が混入している水が前処理フィルタ５に搬送されるタイミング以前であれば、送圧ポンプ６の電源スイッチをＯＮするタイミングは問わない。 Next, the power switch of the pressure pump 6 is turned on, and the pressure pump 6 is driven by the electric power stored in the capacitor 3. As a result, due to the driving force of the pressure pump 6, the water in which the impurities in the impurity-mixed water tank 4 are mixed is transported to the pretreatment filter 5 through the connecting pipe 14 a, and the impurities are mixed in by the pretreatment filter 5 You can remove coarse garbage from the water. Thus, the life of the RO membrane filter 7 can be extended by removing coarse dust using the pretreatment filter 5 before the RO membrane filter 7. Note that the timing for turning on the power switch of the pressure pump 6 does not have to be the timing described above, and water in which impurities in the impurity-mixed water tank 4 are mixed is transported to the pretreatment filter 5 by the pressure pump 6. If it is before the timing to be performed, the timing to turn on the power switch of the pressure pump 6 does not matter.
　次に、加圧ポンプ８の電源スイッチをＯＮにし、蓄電器３に蓄電された電力により加圧ポンプ８を駆動させる。これにより、加圧ポンプ８の駆動力により、前処理フィルタ５から流送された水が連結配管１４ａを介しＲＯ膜フィルタ７に搬送され、ＲＯ膜フィルタ７により海水に含有されている塩分や、井戸水、河川水、湖水、溜池水に含有されているヒ素やダイオキシンなどの不純物が除去された濾過水（飲料水）を生成することができる。また、ＲＯ膜フィルタ７を用いて、塩分、ヒ素やダイオキシンなどの不純物を除去するためには４．５ＭＰａ（４５気圧）以上の大きな圧力をかける必要があるが、本実施形態の水浄化装置１ａに用いられる加圧ポンプ８はＤＣモータを用いているので、不純物が混入している水をＲＯ膜フィルタ７に高効率に通水することができ、４．５ＭＰａ以上の圧力を確保して水から塩分などの不純物を除去することができる。なお、加圧ポンプ８の電源スイッチをＯＮするタイミングについては、送圧ポンプ６と同様、上記のタイミングである必要はなく、加圧ポンプ８により不純物が混入している水をＲＯ膜フィルタ７に搬送させるタイミング以前であれば、加圧ポンプ８の電源スイッチをＯＮするタイミングは問わない。そして、ＲＯ膜フィルタ７により不純物が除去された濾過水は濾過水排出口１１から取り出すことができ、飲料水として用いることができる。 Next, the power switch of the pressure pump 8 is turned on, and the pressure pump 8 is driven by the electric power stored in the battery 3. Thereby, by the driving force of the pressurizing pump 8, the water fed from the pretreatment filter 5 is conveyed to the RO membrane filter 7 via the connection pipe 14a, and the salt content contained in the seawater by the RO membrane filter 7, It is possible to generate filtered water (drinking water) from which impurities such as arsenic and dioxin contained in well water, river water, lake water, and pond water are removed. Further, in order to remove impurities such as salt, arsenic and dioxin using the RO membrane filter 7, it is necessary to apply a large pressure of 4.5 MPa (45 atm) or more, but the water purification apparatus 1a of the present embodiment. Since the pressure pump 8 used in the process uses a DC motor, water in which impurities are mixed can be passed through the RO membrane filter 7 with high efficiency, and a pressure of 4.5 MPa or more is secured. Impurities such as salinity can be removed. The timing for turning on the power switch of the pressurizing pump 8 does not need to be the above timing as in the case of the pumping pump 6, and water in which impurities are mixed by the pressurizing pump 8 is supplied to the RO membrane filter 7. If it is before the timing to convey, the timing which turns ON the power switch of the pressurization pump 8 does not ask | require. And the filtered water from which the impurity was removed by the RO membrane filter 7 can be taken out from the filtered water discharge port 11, and can be used as drinking water.
　次に、ＲＯ膜フィルタ７により不純物が除去された濾過水（飲料水）はオゾン生成機９に流送し、オゾン生成機９により発生させたオゾンとＲＯ膜フィルタ７から流送された濾過水とを混合させてオゾン水が生成される。具体的には、オゾン生成機９は、放電電極に数ｋＷの高電圧を印加して無声放電が生起され、原料気体（酸素又は酸素を含む空気）の酸素を電離させてオゾンが生成される。そして、このオゾン生成機９により生成されたオゾンをＲＯ膜フィルタ７から流送された濾過水にエジェクターで気液混合させることによりオゾン水が生成される。なお、本実施形態のオゾン生成機９は、蓄電器３に蓄電された電力（人力発電機２により発生させた電力）により駆動されている。そして、オゾン生成機９により発生させたオゾンとＲＯ膜フィルタ７から流送された濾過水から生成されたオゾン水はオゾン水排出口１０から取り出すことができる。 Next, the filtered water (drinking water) from which impurities have been removed by the RO membrane filter 7 is sent to the ozone generator 9, and the ozone generated by the ozone generator 9 and the filtered water sent from the RO membrane filter 7. And ozone water is generated. Specifically, the ozone generator 9 generates a silent discharge by applying a high voltage of several kW to the discharge electrode, and ionizing oxygen in the source gas (oxygen or air containing oxygen) to generate ozone. . And ozone water is produced | generated by making the ozone produced | generated by this ozone generator 9 gas-liquid mix with the filtered water sent from RO membrane filter 7 with an ejector. Note that the ozone generator 9 of the present embodiment is driven by the power stored in the battery 3 (power generated by the human power generator 2). The ozone water generated from the ozone generated by the ozone generator 9 and the filtered water sent from the RO membrane filter 7 can be taken out from the ozone water discharge port 10.
　このように、オゾン生成機９により発生させたオゾンとＲＯ膜フィルタ７から流送された濾過水とを混合させたオゾン水を用いることにより、発展途上国のような衛生状態が悪化した地域でも、オゾン水の殺菌作用（大腸菌はオゾン濃度０．９６ｐｐｍ、５秒間で殺菌、ブドウ球菌はオゾン濃度１．０８ｐｐｍ．５秒間で殺菌，インフルエンザウイルスはオゾン濃度０．９６ｐｐｍ、５秒間で殺菌）により感染症を予防し、乳幼児等の死亡率を低減させることができる。 Thus, by using ozone water in which ozone generated by the ozone generator 9 and filtered water flowed from the RO membrane filter 7 are used, even in a region where hygienic conditions such as developing countries have deteriorated, Infected by the bactericidal action of ozone water (E. coli is sterilized at 0.96 ppm for 5 seconds, staphylococci is sterilized at 1.08 ppm for 5 seconds, and influenza virus is sterilized at 0.96 ppm for 5 seconds) Can be prevented and the mortality rate of infants and the like can be reduced.
　以上説明したように、送圧ポンプ６と加圧ポンプ８を駆動させるための電力を人力より発生させる人力発電機２を用いているので、発展途上国のような電気設備が整っていない地域でも不純物が混入している水から安全な飲料水を得ることができる。このように、本実施形態の水浄化装置１ａを用いることにより、アフリカ地域などの水浄化システムが整っていない場所などに、本実施形態の水浄化装置１ａを移動させることができるとともに、移動させた地域が電気設備の整っていない地域でも、水浄化装置１ａを用いて不純物が混入している水から安全な飲料水を生成することができる。 As described above, since the human-powered generator 2 that generates electric power for driving the pressure pump 6 and the pressure pump 8 from human power is used, even in an area where electric facilities such as developing countries are not equipped. Safe drinking water can be obtained from water in which impurities are mixed. Thus, by using the water purification apparatus 1a of the present embodiment, the water purification apparatus 1a of the present embodiment can be moved and moved to a place where a water purification system such as an African region is not provided. Even if the area is not equipped with electrical facilities, safe drinking water can be generated from the water in which impurities are mixed using the water purification device 1a.
　次に、本発明の第２実施形態の水浄化装置について図４および図５を参照にしながら説明する。ここで、図４は本発明の第２実施形態における水浄化装置の組立側面図であり、図５は同水浄化装置のブロック線図である。 Next, a water purification apparatus according to a second embodiment of the present invention will be described with reference to FIGS. 4 and 5. Here, FIG. 4 is an assembled side view of the water purification device in the second embodiment of the present invention, and FIG. 5 is a block diagram of the water purification device.
　本発明の第２実施形態と第１実施形態の異なるところは、第１実施形態の水浄化装置１ａでは、送圧ポンプ６および加圧ポンプ８を用いて不純物が混入している水を搬送させたが、第２実施形態では送圧ポンプ６および加圧ポンプ８を用いず、人力駆動ポンプ１６ａ、１６ｂを用いて不純物が混入している水を搬送させるようにしたところが異なる。なお、第２実施形態においては、第１実施形態と異なるところを中心に説明する。また、第２実施形態では、第１実施形態と同一構成については、同一符号を用い、同一作用効果を奏するものとし説明は省略する。 The difference between the second embodiment and the first embodiment of the present invention is that the water purification apparatus 1a of the first embodiment uses the pressure pump 6 and the pressure pump 8 to transport water in which impurities are mixed. However, the second embodiment is different from the first embodiment in that the water pumping pump 16 and the pressure pump 8 are not used, but water in which impurities are mixed is transported using the human-powered pumps 16a and 16b. Note that the second embodiment will be described with a focus on differences from the first embodiment. Moreover, in 2nd Embodiment, about the same structure as 1st Embodiment, the same code | symbol is used and the same effect is demonstrated and description is abbreviate | omitted.
　第２実施形態では、人力駆動ポンプ１６ａを用いて、人力により不純物混入水タンク４内の不純物が混入している水を前処理フィルタ５に搬送し、人力駆動ポンプ１６ｂを用いて、前処理フィルタ５から流送された水をＲＯ膜フィルタ７に搬送させている。ここで、収納ケース１２ｂと連結配管１４ｂにより連結されている人力駆動ポンプ１６ａ、収納ケース１２ｂと連結配管１４ｃ（１４ｄ）により連結されている人力駆動ポンプ１６ｂについては、収納ケース１２ｂと連結配管１４ｂ、収納ケース１２ｂと連結配管１４ｃ（１４ｄ）を切り離すことにより、収納ケース１２ｂと人力駆動ポンプ１６ａ、収納ケース１２ｂと人力駆動ポンプ１６ｂをそれぞれ分離させることができる。具体的には、第１実施形態と同様に、収納ケース１２ｂの側壁面において、収納ケース１２ｂ内の連結配管１４ｂと収納ケース１２ｂ外の連結配管１４ｂが切り離され、また収納ケース１２ｂ内の連結配管１４ｃと収納ケース１２ｂ外の連結配管１４ｃが切り離され、さらに収納ケース１２ｂ内の連結配管１４ｄと収納ケース１２ｂ外の連結配管１４ｄが切り離されることにより、収納ケース１２ｂと人力駆動ポンプ１６ａ、収納ケース１２ｂと人力駆動ポンプ１６ｂをそれぞれ分離させることができる。ここで、この収納ケース１２ｂ内の連結配管１４ｂ、１４ｃ、１４ｄと収納ケース１２ｂ外の連結配管１４ｂ、１４ｃ、１４ｄは、収納ケース１２ｂの側壁面において着脱可能に結合されている。そして、連結配管１４ｂ、１４ｃ、１４ｄの切り離しは、第１実施形態と同様、それぞれの結合部の周辺を収納ケース１２ｂの方向に押圧することにより行われる。 In the second embodiment, the human-powered pump 16a is used to transport water in which impurities in the impurity-mixed water tank 4 are mixed by human power to the pretreatment filter 5, and the human-powered pump 16b is used to transport the pretreatment filter. The water fed from 5 is conveyed to the RO membrane filter 7. Here, regarding the human-powered pump 16a connected by the storage case 12b and the connection pipe 14b, and the human-powered pump 16b connected by the storage case 12b and the connection pipe 14c (14d), the storage case 12b and the connection pipe 14b, By separating the storage case 12b and the connecting pipe 14c (14d), the storage case 12b and the human-powered pump 16a can be separated from the storage case 12b and the human-powered pump 16b, respectively. Specifically, as in the first embodiment, on the side wall surface of the storage case 12b, the connection pipe 14b in the storage case 12b and the connection pipe 14b outside the storage case 12b are separated, and the connection pipe in the storage case 12b. 14c is disconnected from the connecting pipe 14c outside the storage case 12b, and the connecting pipe 14d inside the storage case 12b is disconnected from the connecting pipe 14d outside the storage case 12b, so that the storage case 12b, the human-powered pump 16a, and the storage case 12b are separated. And the human-powered pump 16b can be separated from each other. Here, the connecting pipes 14b, 14c, 14d in the storage case 12b and the connecting pipes 14b, 14c, 14d outside the storage case 12b are detachably coupled on the side wall surface of the storage case 12b. And disconnection of connection piping 14b, 14c, and 14d is performed by pressing the circumference of each joined part in the direction of storage case 12b like a 1st embodiment.
　このように、第２実施形態の水浄化装置１ｂでは、送圧ポンプ６および加圧ポンプ８を用いていないので収納ケース１２ｂがよりコンパクト（縦横長さ：８００ｍｍ）かつ軽量になり、手押台車１３などを用いて水浄化装置１ｂ移送させる際により移送を容易にすることができる。その他、移送する際には、収納ケース１２ｂを人力駆動ポンプ１６ａおよび人力駆動ポンプ１６ｂと分離させて移送させる点などについては、第１実施形態と同様であるので、説明は省略する。 Thus, in the water purification apparatus 1b of 2nd Embodiment, since the pressure pump 6 and the pressurization pump 8 are not used, the storage case 12b becomes more compact (length and width: 800 mm) and light weight, and it is a handcart. When the water purification device 1b is transferred using 13 or the like, the transfer can be facilitated.
