カソード室2と
前記カソード室2と第1方向(X方向)に対向するアノード室4と、
前記カソード室2および前記アノード室4の間にある中間室3と、
前記中間室3にあり、カソード側孔511を有するカソード側格子51、51Aと、アノード側孔521を有し、前記カソード側格子51、51Aと前記第1方向に並ぶアノード側格子52、52Aとを備えるスペーサ5、5Aと、を備え、

(電解水生成装置1の全体構成)
図1は、電解水生成装置1の概略図である。
電解水生成装置1(以下、装置1と記載)の電解槽10は、内部がカソード室2、中間室3、およびアノード室4に仕切られた三室型である。カソード室2は、図1中左側にあり、アノード室4は、図1中右側にある。中間室3は、カソード室2およびアノード室4の間にある。
図2は、電解槽10の分解斜視図である。
電解槽10は、ケースとして、カソード室フレーム24、中間室フレーム33、アノード室フレーム44を備える。フレーム24、33、44は、平面視でZ方向に長い矩形状、かつ略同一の大きさである。フレーム24、33、44において、縁には複数の孔91がある。孔91にはボルト92(図9)が通され、フレーム24、33、44が位置決めされる。フレーム24、33、44の間には、複数の要素が配置される。中間室フレーム33内には、後述するスペーサ5が配置される。この状態で、各孔91に通されるボルト92がナット93(図9)で締められることで、フレーム24、33、44が締結される。
カソード室フレーム24は、アノード室フレーム44とX方向に逆向きの構成であり、カソード室2を形成する平面視矩形の穴241がある。穴241の底における中央部には、カソード電極22に接続する配線部材222(図9)が通る孔94がある。穴241の底における-Z方向側には、カソード室2に原水を供給する孔242がY方向両側に離れて位置する。孔242は、ユニオン等の継手、配管を介して原水供給口101に接続される。カソード室フレーム24の+Z方向の面には孔243がY方向両側に離れて位置する。孔243は、ユニオン等の継手、配管を介してアルカリ水排出口23に接続され、カソード室2からアルカリ水を排出する。
図3からも、カソード電極22、フッ素メッシュシート252(図2)、陽イオン交換膜21(図2)の縁がフレーム24、33に挟持されることがわかる。
図4は、スペーサ5の-X方向側に位置するネット状クッション材312を示す平面図である。
ネット状クッション材312は、網目がひし形であり、例えばポリエチレン製で弾性を有する。ネット状クッション材312は、中間室フレーム33のZ方向両側の枠間の長さよりも短く、Y方向の幅も収容スペースSの幅よりも短い。ネット状クッション材312は、中間室フレーム33の枠部にかからない位置に配置される。スペーサ5の+X方向側に位置するネット状クッション材314も、上記ネット状クッション材312と同様の構成である。本実施形態では、ネット状クッション材312、314の厚さや、X方向に重ねる枚数を適宜設定することで、中間室3の内圧を容易に調整できる。また、ネット状クッション材312、314により、交換膜21、41にスペーサ5が直接あたることを防ぐことができ、交換膜21、41を保護できる。ネット状クッション材312、314は、スペーサ5の片側のみに設けられていてもよい。
ネット状クッション材316は、カソード側格子51とアノード側格子52との間に設けられてもよい。この場合でも、ネット状クッション材316の厚さや、X方向に重ねる枚数を適宜設定でき、中間室3の内圧を容易に調整できる。このように、スペーサ5の少なくとも片側、または格子51、52間にクッション材があることが好ましい。クッション材は、弾性および透水性を有するものであればよく、ネット状クッション材312、314のほか、例えば不織布であってもよい。
図5は、中間室フレーム33の平面図である。
中間室フレーム33において、-Z方向(Z方向の一方)側の内壁部には、塩水の供給口333がある。供給口333は、-Z方向側の各収容空間SのY方向中央部に対応する位置にあり、中間室フレーム33を貫通する。供給口333は、ユニオン等の継手、配管等を介して循環タンク81の塩水供給側に接続され、-Z方向側のスペーサ5に塩水を供給する。
図6は、カソード側格子51の構成および製作方法を説明するための図である。
図6(A)に示されるように、カソード側格子51において、カソード側孔511は、平面視正方形であり、Z方向およびY方向に直線状に並ぶ。本実施形態では、カソード側孔511は、Z方向に6つ、Y方向に4つ並ぶ。
図7(A)は、カソード側格子51を示し、図7(B)は、アノード側格子52を示す。アノード側格子52は、カソード側格子51と同じものを、姿勢をZ方向に逆にして用いられる。アノード側格子52は、カソード側孔511と同様のアノード側孔521を備える。すなわち、アノード側孔521は、カソード側孔511とZ方向の長さが等しく、かつZ方向に等しい数並ぶ。また、アノード側孔521は、カソード側孔511とY方向の長さが等しく、かつY方向に等しい数並ぶ。
図8は、スペーサ5を収容した状態の中間室フレーム33を示す図である。
スペーサ5の格子51、52において、孔511、521のZ方向に延びる壁部516、526は、Y方向に同位置にあり、X方向(図8の紙面垂直方向)において当接する。このZ方向に延び、Y方向に隣り合う壁部516、526により、塩水をZ方向に案内する通路PがY方向に複数形成される。スペーサ5のY方向両端では、収容空間Sの壁部と、孔511、521のZ方向に延びる壁部516、526とから通路Pが形成される。
図9は、電解槽10の断面図である
カソード側格子51およびアノード側格子52は、収容空間S(中間室3)に流入する塩水を、-Z方向から、Z方向にずれて並ぶカソード側孔511およびアノード側孔521に交互に案内することで、X方向に蛇行させながら、+Z方向に案内する。具体的には、前述したように、+-Z方向の各スペーサ5には、格子51、52によって、Z方向に延びる通路PがY方向に並ぶように形成され、これら各通路Pに塩水は進行する。各通路Pにおいて、塩水は、Z方向にずれて並ぶカソード側孔511およびアノード側孔521に交互に案内され、X方向に蛇行しながら+Z方向に進行する。
(電解槽10Aの全体構成)
図10は、電解槽10Aを示す分解斜視図である。
電解槽10Aが電解槽10と異なる点の一つは、スペーサ5Aが簡素化され、これに伴い、中間室フレーム33Aが、スペーサ5AのY方向に亘って塩水を供給するとともに、スペーサ5Aを通過した塩水をY方向に亘って集める点である。この点については後述する。
図11は、スペーサ5Aおよび中間室フレーム33Aを示す平面図である。図11では、アノード側格子52Aに色を付けて描いている。
スペーサ5Aは、カソード側格子51Aおよびアノード側格子52Aを備える。カソード側格子51Aは、前記実施形態のカソード側格子51を作成するための格子510(図6(C))と同じものである。アノード側格子52Aは、カソード側格子51Aと同じものを使用しており、カソード側格子51Aと姿勢がZ方向に逆である。従って、本実施形態では、前記実施形態とは異なり、格子51A、52AのZ方向両側の突出部512、514、522、524を削除する手間を省くことができる。
図12は、電解槽10Aの断面図である。図12では、アノード室フレーム44Aと中間室フレーム33Aの間の要素を図示するために、アノード室フレーム44Aを完全には中間室フレーム33Aに組付けていない状態の電解槽10Aを描いている。
本実施形態においても、カソード側格子51Aおよびアノード側格子52Aは、中間室3に流入する塩水をカソード側孔511およびアノード側孔521に交互に案内することで、X方向に蛇行させる。そのため、塩水を良好に撹拌でき、中間室3によるイオン供給能力を向上できる。
スペーサ5、5Aは、任意の大きさのものを利用でき、スペーサ5、5Aに対応して電解槽10、10Aの大きさも任意に設計できる。第1実施形態において、スペーサ5の収容数は、平面方向に任意の数設置でき、スペーサ5の数に応じて、中間室フレーム33に仕切り部331、332を設けることができる。
