Description

本発明は、水処理装置に関するものである。
The present invention relates to a water treatment apparatus.

従来から水道管の内部に蓄積するサビは、主に水の内部に溶け込んだ酸素の影響であることが知られている。
そのために、図2に示すように、水道水などの源水を脱気装置aを介して処理水管bへ供給する水処理装置が知られている。
脱気装置aは、負圧発生器cによって発生させた負圧によって源水が含有する酸素などを水から吸引する装置であるが、そのために負圧発生ユニットdを設置する必要があった。
この真空ユニットdは、水槽eに設けた負圧発生器cとポンプpとより構成する。負圧を発生させる場合には、ポンプpを駆動して水槽e内の水を吸引して負圧発生器cに供給し、内部の水路を通過させる。
負圧発生器cは、水の水路をいったん絞り込んでベンチュリー管状に形成してある。そのために水路を通過する水の圧力によって負圧が生じるので、この負圧を水路と直交する方向に接続した負圧管fを介して脱気装置aに供給する構造である。
Conventionally, it is known that the rust accumulated in the water pipe is mainly the influence of oxygen dissolved in the water.
Therefore, as shown in FIG. 2, a water treatment apparatus is known that supplies source water such as tap water to a treated water pipe b through a deaeration device a.
The deaeration device a is a device that sucks oxygen or the like contained in the source water from the water by the negative pressure generated by the negative pressure generator c. For this purpose, it is necessary to install the negative pressure generation unit d.
The vacuum unit d includes a negative pressure generator c and a pump p provided in the water tank e. In the case of generating a negative pressure, the pump p is driven to suck water in the water tank e and supply it to the negative pressure generator c to pass through the internal water channel.
The negative pressure generator c is formed into a venturi shape by once narrowing the water channel. Therefore, since a negative pressure is generated by the pressure of water passing through the water channel, the negative pressure is supplied to the deaerator a through a negative pressure pipe f connected in a direction orthogonal to the water channel.

前記した従来の水処理装置にあっては、次のような問題点がある。
<1>真空ユニットd内では、水槽eの水を長時間循環させ続けて、負圧を発生させる構造である。
そのために水の温度が50℃程度まで上昇する場合があった。
水温が上昇すると、真空性能が低下し、その結果、目的とする脱気性能を低下させる可能性があった。
<2>水槽e内の温度上昇を避けるために、水槽e内に熱交換器gを設置する場合があったが、この熱交換器gへの供給水として脱気回路を流れる水を使用している。そのような構造であると、熱交換器g用の別回路から水の供給をうける必要がなく経済的である。しかし熱を奪った水が受水タンクhに戻ることになり、受水タンクhの水温まで上昇させてしまう場合があった。
<3>真空ユニットの水温を下げるために、熱交換器gとは別に換気扇jを設ける構造も採用されているが、この換気扇jに水槽e内の水のシリカなどが付着して故障の原因となっていた。
<4>また真空ユニットdの水槽e内の水量を一定に維持しておくために補給水用のボールタップiなどの装置が必要であり、そのための保守管理も必要となる。
<5>上記したように、長時間運転を続けると水槽内の水温が上昇するので、夜間は冷却のためにポンプpの運転を停止する必要があった。そのためにポンプ管理のタイマー、トランスなどの部品が必要であった。
<6>真空ユニットdは、上記のような各種の部材、部品を必要とするために、大型の装置となり、設置にも場所と手数を要する、不経済なものであった。
The conventional water treatment apparatus described above has the following problems.
<1> In the vacuum unit d, the water in the water tank e is continuously circulated for a long time to generate a negative pressure.
For this reason, the temperature of the water sometimes increased to about 50 ° C.
When the water temperature is increased, the vacuum performance is lowered, and as a result, the target degassing performance may be lowered.
<2> In order to avoid a temperature rise in the water tank e, there was a case where a heat exchanger g was installed in the water tank e, but water flowing through a deaeration circuit was used as supply water to the heat exchanger g. ing. Such a structure is economical because it is not necessary to receive water from a separate circuit for the heat exchanger g. However, the water from which heat has been removed returns to the water receiving tank h, and the water temperature of the water receiving tank h may be raised.
<3> In order to lower the water temperature of the vacuum unit, a structure in which a ventilation fan j is provided separately from the heat exchanger g is also employed. However, the silica of water in the water tank e adheres to the ventilation fan j and causes failure. It was.
<4> Further, in order to keep the amount of water in the water tank e of the vacuum unit d constant, a device such as a ball tap i for make-up water is necessary, and maintenance management is also required.
<5> As described above, when the operation is continued for a long time, the water temperature in the water tank rises, so that it is necessary to stop the operation of the pump p for cooling at night. For this purpose, parts such as a pump management timer and a transformer were necessary.
Since the <6> vacuum unit d requires various members and parts as described above, the vacuum unit d is a large-sized device, which is uneconomical and requires a lot of space and labor for installation.

上記のような課題を解決するために、本発明の水処理装置は、水道水などの源水を、脱気装置を介して処理水管へ供給する水処理装置であって、脱気装置は、負圧発生器によって発生させた負圧によって未処理の源水が含有する酸素などを水から吸引する装置より構成し、脱気装置と負圧発生器とに加圧状態の未処理水を供給し、負圧発生器においては、動力水の水路の一部を絞り込むことによるベンチュリー効果によって、動力水の水路に負圧を生じさせ、この負圧を負圧管によって前記の脱気装置に供給するように構成し、脱気装置の出口側に接続した処理水管は利用者へ給水可能に構成した、水処理装置を特徴としたものである。
In order to solve the above problems, a water treatment apparatus of the present invention is a water treatment apparatus that supplies source water such as tap water to a treated water pipe via a degassing apparatus, Consists of a device that draws oxygen, etc. contained in untreated source water from the water by the negative pressure generated by the negative pressure generator, and supplies untreated water in a pressurized state to the deaerator and negative pressure generator In the negative pressure generator, a negative pressure is generated in the power water channel by the venturi effect by narrowing a part of the power water channel, and the negative pressure is supplied to the deaerator through the negative pressure pipe. The treated water pipe configured as described above and connected to the outlet side of the deaeration device is characterized by a water treatment device configured to be able to supply water to the user.

本発明の水処理装置は上記のような手段を採用するから、次のような効果を得ることができる。
<1>真空を発生させるために、脱気装置の入り口側で分岐した未処理水の一部を負圧発生器3に供給する構造であり、従来のように特別な真空ユニットが不要である。
<2>従来のように真空ユニットが存在しないから、真空ユニット内で同じ水を循環させて水温を上昇させるようなことがなく、水温上昇に伴う負圧効率の低下、そのための脱気性能の低下、といった問題が一切発生しない。
<3>水温の安定した水で負圧発生を行うことができ、負圧の状態が常に安定しているから、安定した強い脱気性能を期待することができる。
<4>従来のように、負圧発生のためだけに水を循環させる必要がなく、水の温度が上昇しないから熱交換器を設置する必要がない。
<5>真空ユニットが存在しないから、そのための水槽や水量を一定に維持しておくための各種の装置や、長時間運転を続けるポンプの管理のためのブレーカーなどの部品が不要である。
<6>真空ユニットは常時同じ水で運転を続けるから、温度上昇の問題だけでなく、ポンプ周り、水槽内面、換気扇にシリカが付着する問題もあった。しかし本発明の装置は真空ユニットが存在しないので、そのような問題がまったく発生しない。
<7>水温の上昇の問題がないから、夜間に運転を停止して冷却する必要がなく、そのためのタイマーなどの設置や管理が不用である。
<8>真空を発生させるための特別なユニットがないから、装置が小型になり、設置場所が小さく、設置の手数もかからず経済的である。
<9>ポンプを、脱気装置の出口側に設置する装置も考えられるが、そのような構造であると、せっかく脱気処理の終わった水を負圧発生のための動力として使用するため、脱気装置の構造が大きくなってしまう。それに対して本発明の装置では、負圧発生の動力として使用する水は脱気処理していないから、脱気膜の本数を大幅に減少させることができ、装置の小型化、重量の軽減を図ることができる。
<10>また、ポンプを脱気装置の出口側に設置すると、処理水量の安定した確保のためには、入り口側にも未処理水を強制的に脱気装置へ供給するための別のポンプが必要になるといった不経済な問題が発生する。
それに対して本発明の装置では、脱気装置の入り側にポンプを設置してあるから、安定した処理水を確保することができる。
Since the water treatment apparatus of the present invention employs the above-described means, the following effects can be obtained.
<1> In order to generate a vacuum, the structure is such that a part of untreated water branched off at the inlet side of the deaeration device is supplied to the negative pressure generator 3, and no special vacuum unit is required as in the prior art. .
<2> Since there is no vacuum unit as in the past, the same water is not circulated in the vacuum unit to raise the water temperature, and the negative pressure efficiency is lowered due to the rise in water temperature. There will be no problems such as degradation.
<3> Since negative pressure can be generated with water having a stable water temperature and the negative pressure state is always stable, stable strong deaeration performance can be expected.
<4> As in the prior art, it is not necessary to circulate water only for generating negative pressure, and it is not necessary to install a heat exchanger because the temperature of the water does not rise.
<5> Since there is no vacuum unit, there is no need for parts such as a water tank for that purpose, various devices for keeping the amount of water constant, and a breaker for managing a pump that keeps operating for a long time.
<6> Since the vacuum unit always operates with the same water, there was a problem that silica adhered to the periphery of the pump, the inner surface of the water tank, and the ventilation fan, in addition to the problem of temperature rise. However, since the apparatus of the present invention does not have a vacuum unit, such a problem does not occur at all.
<7> Since there is no problem of an increase in water temperature, it is not necessary to stop the operation at night to cool it down, and installation and management of a timer and the like are unnecessary.
<8> Since there is no special unit for generating a vacuum, the apparatus is small, the installation place is small, and the installation is not complicated and economical.
<9> Although the apparatus which installs a pump in the exit side of a deaeration apparatus can also be considered, in order to use the water after deaeration processing as a power for generating negative pressure with such a structure, The structure of the deaerator becomes large. On the other hand, in the apparatus of the present invention, the water used as the power for generating negative pressure is not deaerated, so the number of deaeration membranes can be greatly reduced, and the apparatus can be reduced in size and weight. Can be planned.
<10> When the pump is installed on the outlet side of the degassing device, another pump for forcibly supplying untreated water to the degassing device also on the inlet side in order to ensure a stable amount of treated water There is an uneconomical problem that needs to be done.
On the other hand, in the apparatus of the present invention, since the pump is installed on the entry side of the deaeration device, stable treated water can be secured.

本発明を実施するための最良の形態は、水道水などの源水を、脱気装置を介して処理水管へ供給する水処理装置であって、脱気装置は、負圧発生器によって発生させた負圧によって源水が含有する酸素などを水から吸引する装置より構成し、脱気装置と負圧発生器とに加圧状態の源水を供給し、負圧発生器においては、動力水の水路の一部を絞り込むことによるベンチュリー効果によって、動力水の水路に負圧を生じさせ、この負圧を負圧管によって前記の脱気装置に供給するように構成し、脱気装置の出口側に接続した処理水管は利用者へ給水可能に構成した、水処理装置を特徴としたものである。
The best mode for carrying out the present invention is a water treatment device that supplies source water such as tap water to a treated water pipe via a deaeration device, and the deaeration device is generated by a negative pressure generator. It is composed of a device that sucks oxygen contained in the source water from the negative pressure and supplies the pressurized source water to the deaeration device and the negative pressure generator. A negative pressure is generated in the water channel of the power water by a venturi effect by narrowing a part of the water channel of the water, and this negative pressure is supplied to the deaeration device through the negative pressure pipe. The treated water pipe connected to is characterized by a water treatment device configured to be able to supply water to the user.

以下図面を参照しながら本発明の水処理装置の実施例について説明する。
<1>全体の構成。
本発明の水処理装置は、水道水などの源水を、脱気装置を介して処理水管へ供給する水処理装置である。
具体的には図1に示すように、受水タンク1、脱気装置2、負圧発生器3、および各装置間を連結する管によって構成する。
なお、管の適宜の箇所にバルブを設けたり、処理水を受水タンク1に戻すような配管を設ける場合があるが、本発明の機能に直接関係がないため図1では省略している。
Embodiments of the water treatment apparatus of the present invention will be described below with reference to the drawings.
<1> Overall configuration.
The water treatment apparatus of the present invention is a water treatment apparatus that supplies source water such as tap water to a treated water pipe via a deaeration device.
Specifically, as shown in FIG. 1, the water receiving tank 1, the deaeration device 2, the negative pressure generator 3, and pipes connecting the devices are used.
A valve may be provided at an appropriate position of the pipe or a pipe for returning treated water to the water receiving tank 1 may be provided, but is omitted in FIG. 1 because it is not directly related to the function of the present invention.

<2>受水タンク1。
受水タンク1は、水を貯めるための水槽であり、ビルやマンションの地下や屋上などに設置する。
この受水タンク1へは、水道水や地下水などの源水を、源水供給管p1を介して供給する。
受水タンク1の水位を一定に保つために、受水タンク1内の水面に浮かべたフロートの昇降によって、源水供給用のポンプの運転、停止を行う。
<2> Receiving tank 1.
The water receiving tank 1 is a water tank for storing water, and is installed in the basement or rooftop of a building or condominium.
Source water such as tap water or groundwater is supplied to the water receiving tank 1 through a source water supply pipe p1.
In order to keep the water level of the water receiving tank 1 constant, the pump for supplying the source water is operated and stopped by raising and lowering the float floated on the water surface in the water receiving tank 1.

<3>脱気装置2。
脱気装置2は、源水が含有している酸素などを、水中から除去するための装置である。
そのために、脱気装置2は、酸素透過膜で構成した多数のパイプ21群によって構成する。
そして、このパイプ21群の周囲には負圧状態の空間を形成しておく。
この負圧によって、酸素透過膜のパイプ21を通過する水から、水が含有する酸素などを吸引して排除することができる。
なお、脱気装置2としては酸素透過膜で構成したパイプ21内を負圧状態に形成し、この負圧によって、パイプ21の周囲を通過する水から、水が含有する酸素などを吸引する構造のものを採用することもできる。
<3> Deaerator 2.
The deaeration device 2 is a device for removing oxygen and the like contained in the source water from the water.
For this purpose, the deaeration device 2 is constituted by a large number of pipes 21 group constituted by oxygen permeable membranes.
A space in a negative pressure state is formed around the pipe 21 group.
By this negative pressure, oxygen or the like contained in water can be sucked out from the water passing through the pipe 21 of the oxygen permeable membrane.
The deaerator 2 has a structure in which the inside of the pipe 21 composed of an oxygen permeable membrane is formed in a negative pressure state, and oxygen or the like contained in water is sucked from the water passing around the pipe 21 by this negative pressure. It is also possible to adopt.

<4>ポンプによる水の供給。
受水タンク1と脱気装置2の間には加圧ポンプPを設置する。
このポンプPの動力によって脱気装置2に受水タンク1内の未処理水を供給し、この未処理水を脱気装置2のパイプ21内を通過させる。
パイプ21内を通過して脱気処理のおわった水は出口に接続した処理水管p5に供給する。
この処理水管p5は利用者へ給水するための管であり、例えば家庭の水道の蛇口に接続する。
処理水管p5の一部は、受水タンク1へ戻す。
その結果、ポンプPは常時運転を続けていても、利用者の利用量以上の余剰水は、受水タンク1へ戻ることになる。そのために処理水管p5と受水タンク1の接続部には逆止弁を設けておき、受水タンク1から処理水管p5へ未処理水が浸入することがないように構成する。
<4> Water supply by a pump.
A pressurizing pump P is installed between the water receiving tank 1 and the deaerator 2.
Untreated water in the water receiving tank 1 is supplied to the deaeration device 2 by the power of the pump P, and the untreated water is passed through the pipe 21 of the deaeration device 2.
The water that has passed through the pipe 21 and has been deaerated is supplied to the treated water pipe p5 connected to the outlet.
This treated water pipe p5 is a pipe for supplying water to the user, and is connected to, for example, a faucet of a domestic water supply.
A part of the treated water pipe p5 is returned to the water receiving tank 1.
As a result, even if the pump P is continuously operated, surplus water exceeding the usage amount of the user returns to the water receiving tank 1. For this purpose, a check valve is provided at the connection between the treated water pipe p5 and the water receiving tank 1 so that untreated water does not enter the treated water pipe p5 from the water receiving tank 1.

<5>負圧発生器3。
負圧発生器3は、水が通過する水路をいったん絞り込んでベンチュリー管状に形成した筒体である。
その水路に水を通過させると、絞り込み部分を通過する水の通過速度が上昇し、その圧力によって負圧が生じる。
そのために負圧発生器3には前記のポンプPで加圧した圧力水を、動力水管p6を介して供給する。
この圧力水の通過で発生した負圧を、圧力水の通路と直交する方向に接続した負圧管p4に付与する。
<5> Negative pressure generator 3.
The negative pressure generator 3 is a cylindrical body that is once formed by narrowing down a water passage through which water passes.
When water is passed through the water channel, the passage speed of the water passing through the narrowed portion increases, and a negative pressure is generated by the pressure.
Therefore, the pressure water pressurized by the pump P is supplied to the negative pressure generator 3 through the power water pipe p6.
The negative pressure generated by the passage of the pressure water is applied to the negative pressure pipe p4 connected in the direction orthogonal to the passage of the pressure water.

<6>負圧管の接続。
負圧発生器3において発生した負圧は、負圧管p4を介して脱気装置2に供給する。この負圧によって、脱気装置2内の酸素透過膜製のパイプ21内を通過する水から酸素が吸引されて排出される。
あるいは、負圧管p4を、酸素透過膜で構成したパイプ21側に接続し、パイプ21内を負圧状態に形成し、一方、パイプ21の周囲には水を供給する管を接続して、パイプ21の周囲を通過する水から、水が含有する酸素などをパイプ21内に吸引するような配管方式を採用することもできる。
<6> Connection of negative pressure tube.
The negative pressure generated in the negative pressure generator 3 is supplied to the deaerator 2 through the negative pressure pipe p4. Due to this negative pressure, oxygen is sucked and discharged from the water passing through the pipe 21 made of the oxygen permeable membrane in the deaeration device 2.
Alternatively, the negative pressure pipe p4 is connected to the pipe 21 side made of an oxygen permeable membrane, and the inside of the pipe 21 is formed in a negative pressure state, while a pipe for supplying water is connected around the pipe 21, It is also possible to adopt a piping system in which oxygen or the like contained in water is sucked into the pipe 21 from the water passing around the pipe 21.

<7>処理工程。
源水供給管p1から水道水などを受水タンク1に供給する。
受水タンク1の水は、脱気装置2の供給側に設置したポンプPの動力によって、未処理水管p2を介して脱気装置2に供給される。
未処理水は脱気装置2の内部の酸素透過膜製のパイプ21内を通過する際に、周囲の負圧によって含有している酸素を除去処理する。
処理の終わった水は脱気装置2の出口側に接続した処理水管p5から家庭などの最終使用者に供給する。
一方、ポンプPの出口側で分岐した動力水管p6からの水は、負圧発生器3に供給して、負圧を発生させる。
この負圧を、負圧管p4を介して脱気装置2に供給し、通過中の水から酸素などを脱気する作用を行う。
このように、本発明の水処理装置は脱気装置で処理する前の未処理水の一部を負圧発生器3に戻すことによって負圧を発生させ、この負圧で未処理水の脱気を行うことができる。
<7> Processing step.
Tap water or the like is supplied to the water receiving tank 1 from the source water supply pipe p1.
The water in the water receiving tank 1 is supplied to the deaeration device 2 through the untreated water pipe p2 by the power of the pump P installed on the supply side of the deaeration device 2.
When the untreated water passes through the oxygen-permeable membrane pipe 21 inside the deaerator 2, it removes oxygen contained by the surrounding negative pressure.
The treated water is supplied to a final user such as a household through a treated water pipe p5 connected to the outlet side of the deaerator 2.
On the other hand, the water from the power water pipe p6 branched on the outlet side of the pump P is supplied to the negative pressure generator 3 to generate a negative pressure.
This negative pressure is supplied to the degassing device 2 via the negative pressure pipe p4, and the function of degassing oxygen and the like from the passing water is performed.
As described above, the water treatment apparatus of the present invention generates a negative pressure by returning a part of the untreated water before being treated by the deaeration device to the negative pressure generator 3, and the negative pressure removes the untreated water. I can do it.

<8>他の実施例。
上記の構成は、図1に示すように、ポンプPによって加圧状態の未処理水を、脱気装置2と負圧発生器3とに供給する構造であった。
しかし図2に示すように、受水タンク1と脱気装置2との間に脱気用ポンプPを設置して脱気装置2に加圧状態の未処理水を供給し、受水タンク1と負圧発生器3との間に他のポンプPを設置して負圧発生器3に加圧状態の未処理水を供給する構成を採用することもできる。
<8> Other embodiments.
As shown in FIG. 1, the above configuration is a structure in which untreated water in a pressurized state is supplied to the deaerator 2 and the negative pressure generator 3 by the pump P.
However, as shown in FIG. 2, a degassing pump P is installed between the water receiving tank 1 and the degassing device 2 to supply pressurized untreated water to the degassing device 2. It is also possible to adopt a configuration in which another pump P is installed between the negative pressure generator 3 and untreated water in a pressurized state is supplied to the negative pressure generator 3.
