特許文献1の水処理装置(放電装置)では、処理槽の内部が仕切板によって二つのレーンに仕切られ、仕切板に放電用の貫通孔が形成される。そして、各レーンに一つずつ設けられた電極に電圧を印加すると、仕切板の貫通孔に気泡が形成され、その気泡中で放電が生起して被処理水中に殺菌因子が発生する。特許文献1の水処理装置では、外部から供給された被処理水が二つのレーンに分配される。つまり、この水処理装置では、被処理水の流通経路において、二つのレーンが並列に配置される。 In the water treatment device (discharge device) of Patent Document 1, the inside of the treatment tank is divided into two lanes by a partition plate, and a through hole for discharge is formed in the partition plate. Then, when a voltage is applied to the electrodes provided one by one in each lane, bubbles are formed in the through holes of the partition plate, electric discharge occurs in the bubbles, and a bactericidal factor is generated in the water to be treated. In the water treatment apparatus of Patent Document 1, the water to be treated supplied from the outside is distributed to two lanes. That is, in this water treatment apparatus, two lanes are arranged in parallel in the flow path of the water to be treated.

特開2015−188844号公報JP 2015-188844

被処理水の流通経路において二つのレーンが並列に配置された従来の水処理装置では、二つのレーンに供給される被処理水の流量を均等化するための機構(例えば、流量調節弁)が必要となる。このため、水処理装置の構成の複雑化や製造コストの上昇を招くおそれがあった。 In a conventional water treatment device in which two lanes are arranged in parallel in a flow path of water to be treated, a mechanism (for example, a flow rate control valve) for equalizing the flow rates of water to be treated supplied to the two lanes is provided. You will need it. For this reason, there is a risk that the configuration of the water treatment apparatus will be complicated and the manufacturing cost will increase.

本開示の目的は、水処理装置の構成を簡素化することにある。 An object of the present disclosure is to simplify the configuration of a water treatment apparatus.

本開示の第1の態様は、電気絶縁性の仕切板(23,25)と該仕切板(23,25)によって仕切られた第1槽(16a)及び第2槽(16b)とを有して被処理水を貯留する水処理槽(15)と、上記第1槽(16a)の上記被処理水に接する第1電極(13a)と、上記第2槽(16b)の上記被処理水に接する第2電極(13b)と、上記第1電極(13a)と上記第2電極(13b)に交番波形の電圧を印加する電源(12)とを備え、上記仕切板(23,25)には、該仕切板(23,25)を貫通して水中に位置する放電孔(27)が形成され、上記放電孔(27)に形成された気泡中で放電を生起させることによって、上記第1槽(16a)及び上記第2槽(16b)の被処理水中で殺菌成分を生成させる水処理装置(10)を対象とする。そして、上記第1槽(16a)と上記第2槽(16b)のうち上記第1槽(16a)だけに上記被処理水を導入する導入通路(41)と、上記第1槽(16a)から上記第2槽(16b)へ上記被処理水を流す中間通路(42)と、上記第1槽(16a)と上記第2槽(16b)のうち上記第2槽(16b)だけから上記被処理水を導出する導出通路(43)と、上記中間通路(42)に設けられ、上記第1槽(16a)から上記第2槽(16b)へ上記被処理水が流れているときに、上記第1槽(16a)の上記被処理水と上記第2槽(16b)の上記被処理水を電気的に絶縁する中間絶縁部(32)とを備えるものである。 The first aspect of the present disclosure has an electrically insulating partition plate (23,25) and a first tank (16a) and a second tank (16b) partitioned by the partition plate (23,25). In the water treatment tank (15) for storing the water to be treated, the first electrode (13a) in contact with the water to be treated in the first tank (16a), and the water to be treated in the second tank (16b). The partition plate (23, 25) is provided with a second electrode (13b) in contact with the power supply (12) for applying a voltage of an alternating waveform to the first electrode (13a) and the second electrode (13b). , The first tank is formed by forming a discharge hole (27) located in water through the partition plate (23, 25) and causing a discharge in the bubbles formed in the discharge hole (27). The target is a water treatment apparatus (10) that produces a bactericidal component in the water to be treated in the second tank (16b) and (16a). Then, from the introduction passage (41) for introducing the water to be treated into only the first tank (16a) of the first tank (16a) and the second tank (16b), and from the first tank (16a). The intermediate passage (42) for flowing the water to be treated to the second tank (16b), and the second tank (16b) of the first tank (16a) and the second tank (16b) to be treated. When the water to be treated is flowing from the first tank (16a) to the second tank (16b) provided in the lead-out passage (43) for leading out water and the intermediate passage (42), the first It is provided with an intermediate insulating portion (32) that electrically insulates the water to be treated in one tank (16a) and the water to be treated in the second tank (16b).

第1の態様の水処理装置(10)において、導入通路(41)から第1槽(16a)へ流入した被処理水は、中間通路(42)の中間絶縁部(32)を通過後に第2槽(16b)へ流入し、その後に導出通路(43)を流れる。つまり、この態様の水処理装置(10)では、被処理水の流通経路において、第1槽(16a)と中間絶縁部(32)と第2槽(16b)が直列に配置される。そのため、この態様の水処理装置(10)では、第1槽(16a)と第2槽(16b)のそれぞれにおける被処理水の流量が一致する。従って、この態様によれば、従来は必要であった“第1槽と第2槽のそれぞれにおける被処理水の流量を均等化するための機構”を省略でき、水処理装置(10)の構成を簡素化できる。 In the water treatment apparatus (10) of the first aspect, the water to be treated that has flowed into the first tank (16a) from the introduction passage (41) passes through the intermediate insulating portion (32) of the intermediate passage (42) and then is second. It flows into the tank (16b) and then through the lead-out passage (43). That is, in the water treatment apparatus (10) of this aspect, the first tank (16a), the intermediate insulating portion (32), and the second tank (16b) are arranged in series in the flow path of the water to be treated. Therefore, in the water treatment apparatus (10) of this aspect, the flow rates of the water to be treated in each of the first tank (16a) and the second tank (16b) are the same. Therefore, according to this aspect, it is possible to omit the "mechanism for equalizing the flow rate of the water to be treated in each of the first tank and the second tank" which was conventionally required, and the configuration of the water treatment device (10). Can be simplified.

本開示の第2の態様は、上記第1の態様において、上記導入通路(41)と、上記中間通路(42)と、上記導出通路(43)と、上記水処理槽(15)と、上記中間絶縁部(32)とが、被処理水が流通する水通路(40)を構成し、上記水通路(40)は、該水通路(40)の終端または該水通路(40)の両端だけにおいて大気に開放される気密構造となっているものである。 A second aspect of the present disclosure is, in the first aspect, the introduction passage (41), the intermediate passage (42), the outlet passage (43), the water treatment tank (15), and the above. The intermediate insulating portion (32) constitutes a water passage (40) through which the water to be treated flows, and the water passage (40) is only at the end of the water passage (40) or both ends of the water passage (40). It has an airtight structure that is open to the atmosphere.

第2の態様では、水通路(40)が気密構造となる。このため、水通路(40)の始端に被処理水を押し込むか、水通路(40)の終端から被処理水を吸い出せば、水通路(40)の全体において被処理水を流通させることが可能となる。 In the second aspect, the water passage (40) has an airtight structure. Therefore, if the water to be treated is pushed into the start end of the water passage (40) or the water to be treated is sucked out from the end of the water passage (40), the water to be treated can be circulated throughout the water passage (40). It will be possible.

本開示の第3の態様は、上記第1又は第2の態様において、上記導入通路(41)に設けられて、上記第1槽(16a)へ流入する被処理水と上記第1槽(16a)の被処理水を電気的に絶縁する入口側絶縁部(31,35)と、上記導出通路(43)に設けられて、上記第2槽(16b)の被処理水と上記第2槽(16b)から流出した被処理水を電気的に絶縁する出口側絶縁部(33)とを備えるものである。 A third aspect of the present disclosure is the water to be treated and the first tank (16a) provided in the introduction passage (41) and flowing into the first tank (16a) in the first or second aspect. ) Insulated portion (31,35) on the inlet side that electrically insulates the water to be treated, and the water to be treated in the second tank (16b) and the second tank (the second tank) provided in the lead-out passage (43). It is provided with an outlet-side insulating portion (33) that electrically insulates the water to be treated that has flowed out from 16b).

第3の態様では、水処理装置(10)に入口側絶縁部(31,35)と出口側絶縁部(33)とが設けられる。このため、水処理槽(15)の内部の被処理水と水処理槽(15)の外部の被処理水が電気的に絶縁され、水処理槽(15)の外部への電流の漏洩を防止できる。 In the third aspect, the water treatment apparatus (10) is provided with an inlet side insulating portion (31, 35) and an outlet side insulating portion (33). Therefore, the water to be treated inside the water treatment tank (15) and the water to be treated outside the water treatment tank (15) are electrically insulated to prevent the leakage of electric current to the outside of the water treatment tank (15). it can.

本開示の第4の態様は、上記第2の態様において、上記水通路(40)において上記被処理水を搬送する送水ポンプ(50)を備え、上記送水ポンプ(50)は、上記被処理水と空気の両方を搬送可能に構成されるものである。 A fourth aspect of the present disclosure includes, in the second aspect, a water supply pump (50) for transporting the water to be treated in the water passage (40), and the water supply pump (50) is the water to be treated. It is configured to be able to carry both air and air.

第4の態様では、被処理水と空気の両方を搬送可能な送水ポンプ(50)が、水処理装置(10)に設けられる。このため、送水ポンプ(50)を用いることによって、気密構造の水通路(40)に空気を導入できる。そして、送水ポンプ(50)を用いて水通路(40)へ空気を供給して水通路(40)から被処理水を排出することによって、水通路(40)に被処理水が殆ど残存しない状態を作り出すことが可能となる。従って、この態様では、送水ポンプ(50)を用いて水通路(40)から被処理水を抜き取ることが可能となり、水処理装置(10)の保守作業に要する工数を削減できる。 In the fourth aspect, the water treatment apparatus (10) is provided with a water supply pump (50) capable of transporting both water to be treated and air. Therefore, by using the water pump (50), air can be introduced into the water passage (40) having an airtight structure. Then, by supplying air to the water passage (40) using the water pump (50) and discharging the water to be treated from the water passage (40), almost no water to be treated remains in the water passage (40). Can be created. Therefore, in this embodiment, the water to be treated can be extracted from the water passage (40) by using the water pump (50), and the man-hours required for the maintenance work of the water treatment device (10) can be reduced.

本開示の第5の態様は、上記第2の態様において、上記導出通路(43)に設けられて上記被処理水を搬送する送水ポンプ(50)を備えるものである。 A fifth aspect of the present disclosure includes, in the second aspect, a water supply pump (50) provided in the lead-out passage (43) to convey the water to be treated.

第5の態様では、導出通路(43)に設けられた送水ポンプ(50)が被処理水を吸い込む。このため、水通路(40)のうち送水ポンプ(50)の上流側に位置する部分では、そこを流れる被処理水の圧力が大気圧よりも若干低くなる。従って、この態様によれば、水通路(40)のうち送水ポンプ(50)の上流側に位置する部分からの被処理水の漏洩を抑えることができる。 In the fifth aspect, the water supply pump (50) provided in the lead-out passage (43) sucks the water to be treated. Therefore, in the portion of the water passage (40) located on the upstream side of the water supply pump (50), the pressure of the water to be treated flowing there is slightly lower than the atmospheric pressure. Therefore, according to this aspect, leakage of the water to be treated can be suppressed from the portion of the water passage (40) located on the upstream side of the water supply pump (50).

本開示の第6の態様は、上記第1〜第3の態様のいずれか一つにおいて、上記被処理水を搬送する送水ポンプ(50)を備え、上記中間絶縁部(32)は、該中間絶縁部(32)に流入した上記被処理水を液滴化することによって、上記第1槽(16a)の上記被処理水と上記第2槽(16b)の上記被処理水を電気的に絶縁するように構成され、上記送水ポンプ(50)は、上記被処理水を断続的に搬送するものである。 A sixth aspect of the present disclosure includes, in any one of the first to third aspects, a water supply pump (50) for transporting the water to be treated, and the intermediate insulating portion (32) is intermediate. By dropletizing the water to be treated that has flowed into the insulating portion (32), the water to be treated in the first tank (16a) and the water to be treated in the second tank (16b) are electrically insulated. The water supply pump (50) is configured to intermittently convey the water to be treated.

第6の態様では、送水ポンプ(50)が作動することによって、水通路(40)を被処理水が流れる。送水ポンプ(50)は、被処理水を(連続的ではなく)断続的に搬送する。このため、中間絶縁部(32)には被処理水が断続的に流入することとなり、中間絶縁部(32)において被処理水が液滴化しやすくなる。その結果、中間絶縁部(32)を小型化できる。 In the sixth aspect, the water to be treated flows through the water passage (40) by operating the water supply pump (50). The water pump (50) transports the water to be treated intermittently (not continuously). Therefore, the water to be treated intermittently flows into the intermediate insulating portion (32), and the water to be treated tends to be dropleted in the intermediate insulating portion (32). As a result, the intermediate insulating portion (32) can be miniaturized.

本開示の第7の態様は、上記第1〜第3の態様のいずれか一つにおいて、チューブポンプにより構成されて上記被処理水を搬送する送水ポンプ(50)を備えるものである。 A seventh aspect of the present disclosure comprises, in any one of the first to third aspects, a water pump (50) configured by a tube pump to convey the water to be treated.

第7の態様では、チューブポンプである送水ポンプ(50)が作動することによって、水通路(40)を被処理水が流れる。 In the seventh aspect, the water to be treated flows through the water passage (40) by operating the water pump (50), which is a tube pump.

−送水ポンプ−
図5に示すように、本実施形態の送水ポンプ(50)は、いわゆるチューブポンプである。この送水ポンプ(50)は、ポンプボディ(51)と、ポンプチューブ(53)と、ローター(54)とを一つずつ備える。
-Water pump-
As shown in FIG. 5, the water supply pump (50) of the present embodiment is a so-called tube pump. The water pump (50) includes one pump body (51), one pump tube (53), and one rotor (54).

ポンプボディ(51)は、U字状に湾曲したガイド壁(52)を備える。ポンプチューブ(53)は、例えばゴム製の可撓性を有する管である。ポンプチューブ(53)は、ポンプボディ(51)のガイド壁(52)の内側面に沿って配置される。ローター(54)は、長手方向の中央を通る回転中心軸回りに回転自在な部材である。ローター(54)は、その回転中心軸がガイド壁(52)の内側面の曲率中心と実質的に一致するように配置される。ローター(54)の両端には、ポンプチューブ(53)を押しつぶすためのローラー(55)が一つずつ設けられる。各ローラー(55)は、円柱状に形成され、その中心軸回りに回転自在となっている。 The pump body (51) includes a U-shaped curved guide wall (52). The pump tube (53) is, for example, a rubber tube having flexibility. The pump tube (53) is arranged along the inner surface of the guide wall (52) of the pump body (51). The rotor (54) is a member that is rotatable around a rotation center axis that passes through the center in the longitudinal direction. The rotor (54) is arranged such that its axis of rotation substantially coincides with the center of curvature of the inner surface of the guide wall (52). One roller (55) for crushing the pump tube (53) is provided at both ends of the rotor (54). Each roller (55) is formed in a columnar shape and is rotatable around its central axis.

In the water supply pump (50), one end of the pump tube (53) serves as an suction port (53a), and the other end of the pump tube (53) serves as a discharge port (53b). In the water supply pump (50) shown in FIG. 5, the roller (55) rotates counterclockwise, the lower opening end of the pump tube (53) becomes the suction port (53a), and the upper opening end of the pump tube becomes the suction port (53a).

−水処理装置の運転動作−
水処理装置(10)の運転動作を説明する。水処理装置(10)の作動中は、送水ポンプ(50)のローラー(55)が連続的に回転し、電源(12)が放電水槽(15)の第1電極(13a)と第2電極(13b)に電圧を印加する。
-Operating operation of water treatment equipment-
The operation operation of the water treatment device (10) will be described. During the operation of the water treatment device (10), the roller (55) of the water pump (50) rotates continuously, and the power supply (12) is the first electrode (13a) and the second electrode (13a) of the discharge water tank (15). Apply voltage to 13b).

〈放電水槽の運転動作〉
水処理装置(10)の作動中において、放電水槽(15)は、第1電極(13a)及び第2電極(13b)が被処理水で満たされる。そのため、放電水槽(15)では、第1電極(13a)及び第2電極(13b)と、放電孔(27)とが被処理水に浸かった状態となる。電源(12)が第1電極(13a)と第2電極(13b)に電圧を付与すると、放電部材(25)の放電孔(27)において電流密度が上昇し、発生したジュール熱によって被処理水が気化する。その結果、放電孔(27)において気泡(29)が形成される。
<Operation of discharge water tank>
During the operation of the water treatment device (10), the first electrode (13a) and the second electrode (13b) of the discharge water tank (15) are filled with water to be treated. Therefore, in the discharge water tank (15), the first electrode (13a) and the second electrode (13b) and the discharge hole (27) are in a state of being immersed in the water to be treated. When the power supply (12) applies a voltage to the first electrode (13a) and the second electrode (13b), the current density increases in the discharge hole (27) of the discharge member (25), and the Joule heat generated causes the water to be treated. Evaporates. As a result, bubbles (29) are formed in the discharge holes (27).

図4に示すように、気泡(29)は、放電孔(27)の全体を占める。即ち、放電孔(27)は、その全域が気泡(29)に覆われた状態となる。この状態において、気泡(29)は、第1電極(13a)と第2電極(13b)との間における被処理水を介した導電を阻止する抵抗として機能する。このため、第1槽(16a)の被処理水は第1電極(13a)と実質的に同電位になり、第2槽(16b)の被処理水は第2電極(13b)と実質的に同電位になる。その結果、気泡(29)と水との界面が電極となり、気泡(29)内で絶縁破壊が起こって放電(スパーク放電)が生起する。気泡(29)内で放電が生起すると、第1槽(16a)及び第2槽(16b)に溜まった被処理水の中では、殺菌成分(例えば、水酸ラジカル等の活性種、過酸化水素)が発生する。 As shown in FIG. 4, the bubbles (29) occupy the entire discharge hole (27). That is, the entire discharge hole (27) is covered with bubbles (29). In this state, the bubble (29) functions as a resistor that blocks the conduction between the first electrode (13a) and the second electrode (13b) through the water to be treated. Therefore, the water to be treated in the first tank (16a) has substantially the same potential as the first electrode (13a), and the water to be treated in the second tank (16b) is substantially the same as the second electrode (13b). It becomes the same potential. As a result, the interface between the bubble (29) and water becomes an electrode, dielectric breakdown occurs in the bubble (29), and a discharge (spark discharge) occurs. When an electric discharge occurs in the bubbles (29), in the water to be treated collected in the first tank (16a) and the second tank (16b), a bactericidal component (for example, an active species such as a hydroxide radical, hydrogen peroxide) ) Occurs.

ここで、本実施形態では、電源(12)が交番波形の電圧を第1電極(13a)と第2電極(13b)に印加する、各電極(55a,55b)に印加される電圧の正負が所定時間おきに交互に入れ替わる。そのため、放電孔(27)においてはグロー放電を生起させることなくスパーク放電を生起させることができる。 Here, in the present embodiment, the power supply (12) applies the voltage of the alternating waveform to the first electrode (13a) and the second electrode (13b), and the positive and negative of the voltage applied to each electrode (55a, 55b) is It alternates at regular intervals. Therefore, in the discharge hole (27), a spark discharge can be generated without causing a glow discharge.

つまり、電極(55a,55b)に直流電源が接続されている場合、放電孔(27)における放電の形態は、電流の増加に伴ってスパーク放電からグロー放電に移行する。これに対し、本実施形態では、放電孔(27)における放電の形態がスパーク放電からグロー放電に移行する前に電極(55a,55b)に印加される電圧の正負が入れ替わるので、放電孔(27)ではグロー放電が発生せずにスパーク放電が発生し続ける。このため、放電孔(27)のグロー放電による熱的破壊が抑制され、放電孔(27)の孔径の拡大を抑制することが可能になる。 That is, when a DC power supply is connected to the electrodes (55a, 55b), the form of discharge in the discharge hole (27) shifts from spark discharge to glow discharge as the current increases. On the other hand, in the present embodiment, the positive and negative of the voltage applied to the electrodes (55a, 55b) are switched before the discharge form in the discharge hole (27) shifts from the spark discharge to the glow discharge, so that the discharge hole (27) ), Glow discharge does not occur and spark discharge continues to occur. Therefore, thermal destruction of the discharge hole (27) due to glow discharge is suppressed, and expansion of the hole diameter of the discharge hole (27) can be suppressed.

〈水通路における被処理水の流れ〉
上述したように、水通路(40)は、加湿器の水タンク(90)に接続する両端だけにおいて大気に開放された気密構造となっている(図2を参照)。このため、導出通路(43)に配置された送水ポンプ(50)を作動させると、水通路(40)の全体において被処理水が流通する。
<Flow of water to be treated in the water passage>

送水ポンプ(50)の作動中において、水通路(40)を流れる被処理水の圧力は、送水ポンプ(50)の吸入口(53a)において最も低くなり、送水ポンプ(50)の吐出口(53b)において最も高くなる。また、水通路(40)において、送水ポンプ(50)の上流側に位置する部分の圧力は、大気圧よりも若干低くなる。 During operation of the water supply pump (50), the pressure of the water to be treated flowing through the water passage (40) is the lowest at the suction port (53a) of the water supply pump (50), and the discharge port (53b) of the water supply pump (50). ) Is the highest. Further, in the water passage (40), the pressure of the portion located on the upstream side of the water supply pump (50) is slightly lower than the atmospheric pressure.

It flows into the first tank (16a) of the water tank (15).

It flows into the second tank (16b) of the discharge water tank (15). The intermediate insulating cylinder (32) electrically insulates the water to be treated in the upstream passage (42a) from the water to be treated in the downstream passage (42b) by making the inflowing water to be treated into water droplets and dropping it.

第2槽(16b)において発生した殺菌成分を含む被処理水は、導出通路(43)の上流側通路(43a)と出口側絶縁筒(33)と下流側通路(43b)とを順に通って、加湿器の水タンク(90)へ送り返される。出口側絶縁筒(33)は、流入した被処理水を水滴化して落下させることによって、上流側通路(43a)の被処理水と下流側通路(43b)の被処理水を電気的に絶縁する。 The water to be treated containing the bactericidal component generated in the second tank (16b) passes through the upstream passage (43a), the outlet side insulating cylinder (33), and the downstream passage (43b) of the outlet passage (43) in order. , Sent back to the water tank (90) of the humidifier. The outlet-side insulating cylinder (33) electrically insulates the water to be treated in the upstream passage (43a) from the water to be treated in the downstream passage (43b) by making the inflowing water to be treated into water droplets and dropping it. ..

<Drainage from the water passage>
As described above, the water pump (50), which is a tube pump, can carry both water to be treated and air. Therefore, the water to be treated can be discharged from the water passage (40) by using the water supply pump (50).

具体的に、加湿器の水タンク(90)と水処理装置(10)の導入通路(41)の間を弁等によって遮断し、導入通路(41)の上流側通路(41a)に空気が流入できるようにした状態で送水ポンプ(50)を作動させると、導入通路(41)の上流側通路(41a)へ空気が吸い込まれ、水通路(40)から被処理水が排出されてゆく。そして、送水ポンプ(50)が空気を吸い込むまで送水ポンプ(50)を作動させ続けると、水通路(40)から被処理水がほぼ完全に排出される。 Specifically, the water tank (90) of the humidifier and the introduction passage (41) of the water treatment device (10) are blocked by a valve or the like, and air flows into the upstream passage (41a) of the introduction passage (41). When the water supply pump (50) is operated in this state, air is sucked into the upstream passage (41a) of the introduction passage (41), and the water to be treated is discharged from the water passage (40). Then, when the water supply pump (50) is continuously operated until the water supply pump (50) sucks air, the water to be treated is almost completely discharged from the water passage (40).

The water treatment apparatus (10) of the present embodiment includes a discharge water tank (15), a first electrode (13a), a second electrode (13b), and a power supply (12). The discharge water tank (15) consists of a central partition wall (23) and a discharge member (25) constituting an electrically insulating partition plate, and a first tank (16a) and a second tank partitioned by the partition plate (23, 25). The water to be treated is stored with (16b). The first electrode (13a) is in contact with the water to be treated in the first tank (16a). The second electrode (13b) is in contact with the water to be treated in the second tank (16b). The power supply (12) applies a voltage to the first electrode (13a) and the second electrode (13b). The discharge member (25) constituting the partition plate is formed with a discharge hole (27) located in water through the discharge plate (26) of the discharge member (25). Then, the water treatment apparatus (10) of the present embodiment generates an electric discharge in the bubbles formed in the discharge holes (27), thereby causing the water to be treated in the first tank (16a) and the second tank (16b).

It flows into (16b) and then flows through the lead-out passage (43). That is, in the water treatment apparatus (10) of the present embodiment, the first tank (16a), the intermediate insulating cylinder (32), and the second tank (16b) are arranged in series in the flow path of the water to be treated. Therefore, in the water treatment apparatus (10) of the present embodiment, the flow rates of the water to be treated in each of the first tank (16a) and the second tank (16b) are the same. Therefore, according to the present embodiment, the "mechanism for equalizing the flow rate of the water to be treated in each of the first tank and the second tank", which has been conventionally required, can be omitted, and the water treatment apparatus (10) can be used. The configuration can be simplified.

実施形態2について説明する。本実施形態の水処理装置(10)は、放電水槽(15)が実施形態1の水処理装置(10)と異なる。ここでは、本実施形態の水処理装置(10)について、実施形態1の水処理装置(10)と異なる点を説明する。
<< Embodiment 2 >>
The second embodiment will be described. In the water treatment device (10) of the present embodiment, the discharge water tank (15) is different from the water treatment device (10) of the first embodiment. Here, the difference between the water treatment apparatus (10) of the present embodiment and the water treatment apparatus (10) of the first embodiment will be described.

〈放電水槽〉
図6に示すように、本実施形態の放電水槽(15)の水槽本体(20)は、上面が開口した開放型の容器状に形成される。このため、放電水槽(15)の第1槽(16a)及び第2槽(16b)に貯留された被処理水は、その圧力が大気圧と実質的に等しくなる。
<Discharge water tank>
As shown in FIG. 6, the water tank body (20) of the discharge water tank (15) of the present embodiment is formed in the shape of an open container having an open upper surface. Therefore, the pressure of the water to be treated stored in the first tank (16a) and the second tank (16b) of the discharge water tank (15) becomes substantially equal to the atmospheric pressure.

〈導入通路、噴霧ノズル〉
本実施形態の導入通路(41)には、入口側絶縁筒(31)に代えて噴霧ノズル(35)が設けられる。この噴霧ノズル(35)は、入口側絶縁部を構成する。噴霧ノズル(35)は、導入通路(41)の終端に設けられる。また、噴霧ノズル(35)は、第1槽(16a)に貯留された被処理水の水面の上方に配置され、下方に向かって被処理水を噴霧する。噴霧ノズル(35)から噴霧された被処理水は、水滴となって落下する。落下する水滴の間には、空気が存在する。このため、水通路(40)では、導入通路(41)の被処理水と第1槽(16a)の被処理水が電気的に絶縁される。
<Introduction passage, spray nozzle>
The introduction passage (41) of the present embodiment is provided with a spray nozzle (35) instead of the inlet-side insulating cylinder (31). This spray nozzle (35) constitutes an inlet-side insulating portion. The spray nozzle (35) is provided at the end of the introduction passage (41). Further, the spray nozzle (35) is arranged above the surface of the water to be treated stored in the first tank (16a), and sprays the water to be treated downward. The water to be treated sprayed from the spray nozzle (35) falls as water droplets. There is air between the falling water droplets. Therefore, in the water passage (40), the water to be treated in the introduction passage (41) and the water to be treated in the first tank (16a) are electrically insulated.

〈中間通路〉
中間通路(42)の上流側通路(42a)は、一端が水槽本体(20)の底壁部(21)を貫通して第1槽(16a)に開口する。本実施形態の水処理装置では、中間通路(42)の上流側通路(42a)に送水ポンプ(50)が設けられる。送水ポンプは、第1槽(16a)から吸い込んだ被処理水を、中間絶縁筒(32)へ向けて吐出する。
<Intermediate passage>
One end of the upstream passage (42a) of the intermediate passage (42) penetrates the bottom wall portion (21) of the water tank main body (20) and opens to the first tank (16a). In the water treatment apparatus of the present embodiment, the water supply pump (50) is provided in the upstream passage (42a) of the intermediate passage (42). The water supply pump discharges the water to be treated sucked from the first tank (16a) toward the intermediate insulating cylinder (32).

〈導出通路、出口側絶縁筒〉
導出通路(43)の上流側通路(43a)は、一端が水槽本体(20)の底壁部(21)を貫通して第2槽(16b)に開口する。本実施形態の出口側絶縁筒(33)は、放電水槽(15)の下方に配置される。第2槽(16b)の被処理水は、重力によって上流側通路(43a)を通って出口側絶縁筒(33)へ流入する。
<Outlet passage, outlet side insulation cylinder>
One end of the upstream passage (43a) of the lead-out passage (43) penetrates the bottom wall portion (21) of the water tank main body (20) and opens to the second tank (16b). The outlet-side insulating cylinder (33) of the present embodiment is arranged below the discharge water tank (15). The water to be treated in the second tank (16b) flows into the outlet side insulating cylinder (33) through the upstream side passage (43a) by gravity.

上記の各実施形態の水処理装置(10)では、送水ポンプ(50)を断続的に作動させてもよい。具体的には、送水ポンプの起動と停止を所定時間(例えば、1秒間)が経過する毎に交互に繰り返してもよい。実施形態1の水処理装置において送水ポンプを断続的に作動させると、各絶縁筒(31,32,33)に被処理水が間欠的に流入する。このため、各絶縁筒(31,32,33)では、流入した被処理水の水滴化が促進される。その結果、各絶縁筒(31,32,33)の上流側の被処理水と下流側の被処理水との間の電気絶縁性を高めることができる。
<< Other Embodiments >>
-First modification-
In the water treatment apparatus (10) of each of the above embodiments, the water pump (50) may be operated intermittently. Specifically, the start and stop of the water supply pump may be alternately repeated every time a predetermined time (for example, 1 second) elapses. When the water supply pump is operated intermittently in the water treatment apparatus of the first embodiment, the water to be treated intermittently flows into each insulating cylinder (31, 32, 33). Therefore, in each insulating cylinder (31, 32, 33), the inflow of water to be treated is promoted to become droplets. As a result, the electrical insulation between the water to be treated on the upstream side and the water to be treated on the downstream side of each insulating cylinder (31, 32, 33) can be improved.

このように、本変形例の水処理装置(10)は、被処理水を搬送する送水ポンプ(50)を備える。本変形例の水処理装置(10)において、中間絶縁筒(32)は、中間絶縁筒(32)に流入した被処理水を液滴化することによって、第1槽(16a)の被処理水と第2槽(16b)の被処理水を電気的に絶縁するよう。そして、送水ポンプ(50)は、被処理水を断続的に搬送する。 As described above, the water treatment apparatus (10) of the present modification includes a water supply pump (50) for transporting the water to be treated. In the water treatment apparatus (10) of this modified example, the intermediate insulating cylinder (32) drops the water to be treated that has flowed into the intermediate insulating cylinder (32) into droplets, so that the water to be treated in the first tank (16a) is treated. And electrically insulate the water to be treated in the second tank (16b). Then, the water supply pump (50) intermittently conveys the water to be treated.

本変形例の水処理装置(10)では、送水ポンプ(50)が作動することによって、水通路(40)を被処理水が流れる。送水ポンプ(50)は、被処理水を(連続的ではなく)断続的に搬送する。このため、中間絶縁筒(32)には被処理水が間欠的に流入することとなり、中間絶縁筒(32)において被処理水が液滴化しやすくなる。その結果、中間絶縁筒(32)を小型化できる。 In the water treatment device (10) of this modified example, the water to be treated flows through the water passage (40) by operating the water supply pump (50). The water pump (50) transports the water to be treated intermittently (not continuously). Therefore, the water to be treated intermittently flows into the intermediate insulating cylinder (32), and the water to be treated tends to be dropleted in the intermediate insulating cylinder (32). As a result, the intermediate insulating cylinder (32) can be miniaturized.

−第2変形例−
上記の各実施形態および変形例の水処理装置(10)では、チューブポンプ以外の形式のポンプ(例えば、インペラを有するポンプ)が、送水ポンプ(50)として用いられていてもよい。
-Second modification-
In the water treatment apparatus (10) of each of the above embodiments and modifications, a pump of a type other than the tube pump (for example, a pump having an impeller) may be used as the water supply pump (50).

−第3変形例−
図7に示すように、上記の各実施形態および各変形例の水処理装置(10)には、加湿器の水タンク(90)から流出した水の一部が被処理水として導入されてもよい。本変形例によれば、水処理装置(10)を通過する被処理水の流量を低く抑えることができる。その結果、各絶縁筒(31,32,33)では、落下する水滴の間隔が広がり、各絶縁筒(31,32,33)の上流側の被処理水と下流側の被処理水との間の電気絶縁性を高めることができる。
-Third variant-
As shown in FIG. 7, even if a part of the water flowing out from the water tank (90) of the humidifier is introduced as the water to be treated into the water treatment apparatus (10) of each of the above-described embodiments and modifications. Good. According to this modification, the flow rate of the water to be treated passing through the water treatment apparatus (10) can be suppressed to a low level. As a result, in each insulating cylinder (31,32,33), the interval between the falling water droplets is widened, and between the water to be treated on the upstream side and the water to be treated on the downstream side of each insulating cylinder (31,32,33). The electrical insulation of the product can be improved.

−第4変形例−
図8に示すように、上記の各実施形態および各変形例の水処理装置(10)は、送水ポンプ(50)に代えてベンチュリー管(56)を備えていてもよい。
-Fourth modification-
As shown in FIG. 8, the water treatment apparatus (10) of each of the above-described embodiments and modifications may include a Venturi pipe (56) instead of the water pump (50).

ベンチュリー管(56)は、中間部が括れた形状の円管である。ベンチュリー管(56)の括れた部分は、縮径部(57)である。ベンチュリー管(56)は、加湿器の水タンク(90)から流出した水が流れる管路に設けられる。本変形例の水処理装置(10)において、導入通路(41)の入口端は、ベンチュリー管(56)の縮径部(57)の上流側に接続され、導出通路(43)の出口端は、ベンチュリー管(56)の縮径部(57)に接続される。 The Venturi tube (56) is a circular tube with a constricted middle part. The constricted portion of the Venturi tube (56) is the reduced diameter portion (57). The Venturi pipe (56) is provided in the pipe where the water flowing out from the water tank (90) of the humidifier flows. In the water treatment apparatus (10) of this modification, the inlet end of the introduction passage (41) is connected to the upstream side of the reduced diameter portion (57) of the Venturi pipe (56), and the outlet end of the outlet passage (43) is. , Connected to the reduced diameter portion (57) of the Venturi tube (56).

ベンチュリー管(56)では、縮径部(57)を流れる水の圧力が、縮径部(57)の上流側の部分を流れる水の圧力よりも低い。本変形例の水処理装置(10)において、導入通路(41)の入口端における被処理水の圧力は、縮径部(57)の上流側の部分を流れる水の圧力と実質的に等しく、導出通路(43)の出口端における被処理水の圧力は、縮径部(57)を流れる水の圧力と実質的に等しい。従って、本変形例の水処理装置(10)の水通路では、導入通路(41)の入口端と導出通路(43)の出口端の圧力差によって被処理水が流れる。 In the Venturi tube (56), the pressure of water flowing through the reduced diameter portion (57) is lower than the pressure of water flowing through the upstream portion of the reduced diameter portion (57). In the water treatment apparatus (10) of this modification, the pressure of the water to be treated at the inlet end of the introduction passage (41) is substantially equal to the pressure of the water flowing on the upstream side of the reduced diameter portion (57). The pressure of the water to be treated at the outlet end of the lead-out passage (43) is substantially equal to the pressure of the water flowing through the reduced diameter portion (57). Therefore, in the water passage of the water treatment apparatus (10) of this modified example, the water to be treated flows due to the pressure difference between the inlet end of the introduction passage (41) and the outlet end of the outlet passage (43).

吸気用ベンチュリー管(60)は、中間部が括れた形状の円管である。吸気用ベンチュリー管(60)の括れた部分は、縮径部(61)である。吸気用ベンチュリー管(60)は、加湿器の水タンク(90)から流出した水が流れる管路に設けられる。吸気用ベンチュリー管(60)の縮径部(61)には、空気吸入管(62)の一端が接続される。空気吸入管(62)の他端は、大気中に開口する。 The intake Venturi tube (60) is a circular tube having a constricted middle portion. The constricted portion of the intake Venturi pipe (60) is the reduced diameter portion (61). The intake Venturi pipe (60) is provided in the pipe where the water flowing out from the water tank (90) of the humidifier flows. One end of the air suction pipe (62) is connected to the reduced diameter portion (61) of the intake venturi pipe (60). The other end of the air suction pipe (62) opens into the atmosphere.

本変形例の水処理装置(10)において、導入通路(41)の入口端と導出通路(43)の出口端とは、いずれも吸気用ベンチュリー管(60)における縮径部(61)の下流側の部分に接続される。また、吸気用ベンチュリー管(60)では、導入通路(41)の入口端の下流側に導出通路(43)の出口端が配置される。 In the water treatment apparatus (10) of this modified example, the inlet end of the introduction passage (41) and the outlet end of the outlet passage (43) are both downstream of the reduced diameter portion (61) in the intake venturi pipe (60). Connected to the side part. Further, in the intake venturi pipe (60), the outlet end of the outlet passage (43) is arranged on the downstream side of the inlet end of the introduction passage (41).

吸気用ベンチュリー管(60)では、縮径部(61)を流れる水の圧力が大気圧よりも低くなり、空気が空気吸入管(62)を通って縮径部(61)へ吸い込まれる。縮径部(61)から流出する水には、空気吸入管(62)から流入した空気が混入する。本変形例の水処理装置(10)では、空気の混入した水が被処理水として導入通路(41)へ流入し、この被処理水が水通路(40)を流れる。 In the intake venturi pipe (60), the pressure of water flowing through the reduced diameter portion (61) becomes lower than the atmospheric pressure, and air is sucked into the reduced diameter portion (61) through the air suction pipe (62). The water flowing out from the reduced diameter portion (61) is mixed with the air flowing in from the air suction pipe (62). In the water treatment apparatus (10) of this modified example, water mixed with air flows into the introduction passage (41) as water to be treated, and the water to be treated flows through the water passage (40).

上記の各実施形態および各変形例の水処理装置(10)の絶縁筒(31,32,33)では、内部の空気が被処理水に溶解することによって、内部の空気の量が徐々に減少するおそれがある。絶縁筒(31,32,33)内の空気の量が減少すると、絶縁筒(31,32,33)の電気絶縁性能が低下するおそれがある。一方、本変形例の水処理装置(10)では、空気の混入した水が被処理水として水通路(40)を流れる。従って、本変形例では、絶縁筒(31,32,33)に空気が補給され、絶縁筒(31,32,33)内の空気の量が確保されるため、絶縁筒(31,32,33)の電気絶縁性能を長期に亘って維持できる。 In the insulating cylinders (31, 32, 33) of the water treatment apparatus (10) of each of the above embodiments and modifications, the amount of air inside gradually decreases as the air inside dissolves in the water to be treated. There is a risk of If the amount of air in the insulating cylinder (31,32,33) decreases, the electrical insulation performance of the insulating cylinder (31,32,33) may deteriorate. On the other hand, in the water treatment apparatus (10) of this modified example, water mixed with air flows through the water passage (40) as water to be treated. Therefore, in this modification, air is supplied to the insulating cylinder (31,32,33) and the amount of air in the insulating cylinder (31,32,33) is secured, so that the insulating cylinder (31,32,33) is secured. ) Can maintain the electrical insulation performance for a long period of time.

−第6変形例−
上記の各実施形態および各変形例の水処理装置(10)の用途は、加湿用の水の浄化に限定されない。加湿用の水の浄化以外の用途に用いられる場合、水処理装置(10)は、導入通路(41)が水道に接続されていてもよい。実施形態1の水処理装置(10)の導入通路(41)を水道に接続した場合、その水通路(40)は、その終端だけにおいて大気に開放された気密構造となる。この場合は、導入通路(41)に被処理水として導入される水道水の圧力だけによって、水通路(40)において被処理水が流通するため、送水ポンプ(50)が不要となる。
-Sixth variant-
