As a result of intensive studies to achieve the above object, the present inventors have completed the present invention through trial and error.

２）前記水はＮａ＋型のイオン交換体で軟水化処理され、かつ、脱塩室に流す水と濃縮室に流す水の割合が１：０．５〜１．０であることを特徴とするものである。
In order to achieve the above object, the pure water apparatus of the present invention is an electric regeneration type pure water apparatus in which an anion membrane and a cation membrane of an anode and a cathode are alternately divided into a plurality of concentration chambers and a desalting chamber.

本発明の最良の実施例について、以下に図を用いて詳細に述べる。 The best embodiment of the present invention will be described in detail below with reference to the drawings.
図１は、本発明の純水装置の実施例１の構成図である。図２は、本発明の純水装置の実施例１の脱塩室の構成図である。図３は、本発明の純水装置の実施例１の電解槽部分の組立図である。図４は、本発明の脱塩室の供給水分散孔の構造を示した構成図である。本発明の実施例１の純水装置（１４）では、陰極（１０）と陽極（１１）の間をアニオン膜（７）とカチオン膜（６）で交互に複数の濃縮室（１２）と脱塩室（１３）に区切ってある。原水をポンプ（１）で加圧し、逆浸透膜（２）によって得られた透過水をＮａ＋型のイオン交換体を充填したイオン交換体塔（３）で、Ｃａ＋２、Ｍｇ＋２イオンを除去した軟水を脱塩室（１３）及び濃縮室（１２）に、それぞれ別々に、直列に流す。脱塩室（１３）には、前記軟水が水供給口（１５）から流入し、水分散孔（１６）から均一に脱塩室内へ供給され、水排出口（１７）から排出され、次の濃縮室（１２）へ流入する。脱塩室（１３）にはイオン交換体として、アニオン交換体（９）及びカチオン交換体（８）が水の流れに対して複数に分割されて交互に充填してあり、その割合はアニオン交換体を１とすると、これに対し、カチオン交換体が０．５〜０．７になるように構成されている。濃縮室（１２）には、カーボン繊維（５）が充填されている。カーボン繊維の代わりにイオン交換体を充填してもよい。 FIG. 1 is a configuration diagram of Embodiment 1 of a pure water apparatus according to the present invention. FIG. 2 is a configuration diagram of a desalting chamber of the first embodiment of the pure water apparatus of the present invention. FIG. 3 is an assembly diagram of the electrolytic cell part of Example 1 of the pure water apparatus of the present invention. FIG. 4 is a configuration diagram showing the structure of the feed water dispersion hole of the desalination chamber of the present invention. In the deionized water device (14) of Example 1 of the present invention, a plurality of concentration chambers (12) are removed between the cathode (10) and the anode (11) alternately with an anion membrane (7) and a cation membrane (6). It is divided into a salt room (13). The raw water is pressurized with the pump (1), and the permeated water obtained by the reverse osmosis membrane (2) is removed from the Ca +2 and Mg +2 ions in the ion exchanger tower (3) packed with Na + type ion exchangers. The soft water thus made is allowed to flow separately in series in the desalting chamber (13) and the concentration chamber (12). The soft water flows into the desalting chamber (13) from the water supply port (15), is uniformly supplied from the water dispersion hole (16) to the desalting chamber, is discharged from the water discharge port (17), and It flows into the concentration chamber (12). In the desalting chamber (13), as an ion exchanger, an anion exchanger (9) and a cation exchanger (8) are divided into a plurality of water flows and alternately filled, and the ratio is anion exchange. If the body is 1, the cation exchanger is configured to be 0.5 to 0.7. The concentration chamber (12) is filled with carbon fibers (5). An ion exchanger may be filled instead of the carbon fiber.
イオン交換体塔（３）から脱塩室（１３）及び濃縮室（１２）への流量は、流量計（４）で管理されている。 The flow rate from the ion exchanger tower (3) to the desalting chamber (13) and the concentrating chamber (12) is controlled by a flow meter (4).
イオン交換体塔（３）のＮａ＋型のイオン交換体は、Ｃａ＋２、Ｍｇ＋２イオンを除去すると同時に得られた軟水のｐＨが８〜９のアルカリ性になるので、濃縮室においてスケールの発生を防止することができる。 The Na + type ion exchanger in the ion exchanger tower (3) removes Ca +2 and Mg +2 ions, and at the same time, the pH of the soft water obtained becomes alkaline with 8-9, so scale is not generated in the concentration chamber. Can be prevented.
本発明の実施例１の純水装置（１４）では、脱塩室（１３）と濃縮室（１２）の流れの割合を１：０．５〜０．８としてある。濃縮室（１２）のイオン濃度を高くして陽極（１１）と陰極（１０）の間の電気抵抗を下げて電流を流れやすくするためである。脱塩室（１３）と濃縮室（１２）の流れの割合は、１：０．５〜１の間であってもよい。 In the pure water apparatus (14) of Example 1 of the present invention, the flow ratio of the desalting chamber (13) and the concentration chamber (12) is set to 1: 0.5 to 0.8. This is because the ion concentration in the concentration chamber (12) is increased to lower the electrical resistance between the anode (11) and the cathode (10), thereby facilitating current flow. The ratio of the flow of the desalting chamber (13) and the concentration chamber (12) may be between 1: 0.5 and 1.
なお、電気抵抗を下げる手段としては、脱塩室（１３）と濃縮室（１２）の間隔を狭く（１ｍｍ以下）することにより実現できるが、圧力損失が増大し、構造が複雑になり、好ましくない。 As a means for lowering the electric resistance, it can be realized by narrowing the interval between the desalting chamber (13) and the concentrating chamber (12) (1 mm or less), but the pressure loss increases, the structure becomes complicated, Absent.
脱塩室（１３）に充填してあるイオン交換体はアニオン交換体（９）とカチオン交換体（８）であるが、アニオン交換体（９）の割合を多くすることによって、除去しにくい弱イオンであるシリカが、より速やかに除去できる。 The ion exchanger filled in the desalting chamber (13) is an anion exchanger (9) and a cation exchanger (8), but it is difficult to remove by increasing the proportion of the anion exchanger (9). Silica which is an ion can be removed more rapidly.
脱塩室（１３）に充填するイオン交換体であるアニオン交換体（９）及びカチオン交換体（８）は、厚さ方向に所定の厚さになるようにプレスし、温水に浸漬させた後、冷水に浸漬させてある。本発明の実施例１では、温水の温度は、４０℃〜５０℃、冷水の温度は、５℃〜１０℃となるようにしてある。 The anion exchanger (9) and the cation exchanger (8), which are ion exchangers filled in the desalting chamber (13), are pressed to a predetermined thickness in the thickness direction and immersed in warm water. It is immersed in cold water. In Example 1 of the present invention, the temperature of hot water is 40 ° C. to 50 ° C., and the temperature of cold water is 5 ° C. to 10 ° C.
イオン交換体の形態はいろいろあるが、繊維状のものは単独では強度が弱い。従って、本発明の実施例１では、カチオン繊維と、ポリエステル繊維あるいはポリプロピレン繊維を一定の割合、例えば、カチオン繊維を６０％〜７０％、残りをポリエステル繊維あるいはポリプロピレン繊維として混合し、不織布に加工し、綿状にしたものをカチオン交換体（８）とした。また、アニオン繊維と、ポリエステル繊維あるいはポリプロピレン繊維を一定の割合、例えば、アニオン繊維を６０％〜７０％、残りをポリエステル繊維あるいはポリプロピレン繊維として混合し、不織布に加工し、綿状にしたものをアニオン交換体（９）とした。カチオン交換体（８）とアニオン交換体（９)には空隙があるため、そのまま脱塩室に充填すると、充填密度が低い。従って、本発明の実施例１では、充填密度を上げるために、プレスしてある。 There are various forms of ion exchangers, but the fibrous one alone is weak in strength. Therefore, in Example 1 of the present invention, the cation fiber and the polyester fiber or the polypropylene fiber are mixed in a certain ratio, for example, 60% to 70% of the cation fiber and the rest as the polyester fiber or the polypropylene fiber, and processed into a nonwoven fabric. A cotton-like product was used as a cation exchanger (8). Also, anionic fibers and polyester fibers or polypropylene fibers are mixed in a certain proportion, for example, 60% to 70% of anionic fibers and the rest are mixed as polyester fibers or polypropylene fibers, processed into a non-woven fabric and made into a cotton-like anion. It was set as the exchanger (9). Since there are voids in the cation exchanger (8) and the anion exchanger (9), if the desalting chamber is filled as it is, the packing density is low. Therefore, in Example 1 of the present invention, pressing is performed to increase the packing density.
よって、本発明の実施例１の純水装置によれば、水の流れが均一で、シリカ等の弱イオンも効果的に除去できる。 Therefore, according to the pure water apparatus of Example 1 of this invention, the flow of water is uniform and weak ions, such as a silica, can also be removed effectively.
