Description

本発明は、医療施設での個別透析および在宅で慢性腎不全患者が使用することができる、一人または二人用として好適な個人透析用の人工透析用水製造装置と、それを用いた透析液製造装置に関する。   The present invention relates to an apparatus for producing artificial dialysis water for personal dialysis suitable for one or two persons that can be used by a patient with chronic renal failure at individual dialysis at home or at home, and dialysis fluid production using the apparatus. Relates to the device.

従来、電解水製造装置と逆浸透膜装置（ＲＯ装置）を組み合わせた透析用水および透析液の製造装置が知られている（特許文献１）。
これらは医療施設において、多人数の患者の治療に対応するための装置であることから、高い製造能力を有しているものであり、電解水製造装置への原水（水道水）供給量は５００Ｌ／ｈｒを超える量となる。そのため、特許文献1の人工透析用水製造装置では、４台の電解水製造装置を用いた水素含有透析用水の製造例が示されている。
また、特許文献２に示されるように、従来の電解水製造装置は電解効率を高めるために、供給水の電気伝導度を１００μＳ／ｃｍ以上とするようにイオン分を加えて所望する溶存水素濃度を達成しているため、使用する原水に制限を受けるものであった。 2. Description of the Related Art Conventionally, a dialysis water and dialysate manufacturing apparatus is known that combines an electrolyzed water manufacturing apparatus and a reverse osmosis membrane apparatus (RO apparatus) (Patent Document 1).
Since these are devices for treating a large number of patients in a medical facility, they have a high production capacity, and the amount of raw water (tap water) supplied to the electrolyzed water production device is 500L. The amount exceeds / hr. Therefore, in the artificial dialysis water production apparatus of Patent Document 1, an example of producing hydrogen-containing dialysis water using four electrolyzed water production apparatuses is shown.
Moreover, as shown in Patent Document 2, in order to increase the electrolysis efficiency of the conventional electrolyzed water production apparatus, a desired dissolved hydrogen concentration is obtained by adding an ionic component so that the electric conductivity of the supplied water is 100 μS / cm or more. Therefore, the raw water used is limited.

医療施設における個別透析や家庭での透析治療においては、大型装置は必要ではなく、小型の装置であることが望まれる。
また、地域によってはイオン分の少ない低電導度の水道水等を原水として使用する場合もあるため、低電導度の原水でも十分な治療効果をもたらす溶存水素濃度が得られるような電解効率の高い電解水製造装置が求められている。 In individual dialysis in a medical facility and dialysis treatment at home, a large device is not necessary, and a small device is desired.
Also, depending on the region, tap water with low conductivity and low conductivity may be used as raw water, so the electrolytic efficiency is high so that dissolved hydrogen concentration can be obtained with sufficient therapeutic effect even with low conductivity raw water. There is a need for an electrolyzed water production apparatus.

また、必要に応じて軟水器１の前にプレフィルターを設置することができる。 <Water production equipment for artificial dialysis for personal dialysis>
This will be described with reference to FIG.
The raw water (tap water or groundwater) and the water softener 1 are connected by a raw water line 11. At this time, when used at home, the raw water inlet and the faucet of the water softener 1 can be connected by the raw water line 11.
The raw water is sent to the water softener 1 by driving a raw water pump 21 installed in the raw water line 11.
In addition, when connected to the faucet of a water supply, the raw | natural water pump 21 can also be abbreviate | omitted by utilizing a water pressure.
Moreover, a pre filter can be installed in front of the water softener 1 as needed.

軟水器１は、原水中の硬度成分（カルシウム、マグネシウムイオン等）の濃度を低減させるためのものである。
軟水器１は、市販の軟水器を使用することができる。
軟水器１で硬度成分の濃度が低減された水は、ライン１２から吸着装置２に送られる。 The water softener 1 is for reducing the concentration of hardness components (calcium, magnesium ions, etc.) in raw water.
As the water softener 1, a commercially available water softener can be used.
The water whose hardness component concentration is reduced in the water softener 1 is sent from the line 12 to the adsorption device 2.

吸着装置２は、ケース内に活性炭、ゼオライト等の吸着剤が充填されたものである。
吸着装置２は、残留塩素等を吸着除去するための装置である。
吸着装置２で残留塩素等が除去された水は、ライン１３から電解水製造装置３に送られる。 The adsorption device 2 is a case in which an adsorbent such as activated carbon or zeolite is filled in a case.
The adsorption device 2 is a device for adsorbing and removing residual chlorine and the like.
The water from which residual chlorine and the like have been removed by the adsorption device 2 is sent from the line 13 to the electrolyzed water production device 3.

電解水製造装置３は、軟水装置１と吸着装置２で処理した前処理水を電気分解して、電解陰極水と電解陽極水を得るためのものである。
電解水製造装置自体は公知のものであるが（例えば、特許文献１、２参照）、本発明で使用する電解水製造装置３は、一人または二人用の個人透析用の人工透析用水製造装置として好適な構造となっている。
電解水製造装置３は、電解水製造装置と、軟水器１および吸着装置２およびＲＯ装置が一体にされた装置にすることもできる。 The electrolyzed water production device 3 is for electrolyzing pretreated water treated by the soft water device 1 and the adsorption device 2 to obtain electrolytic cathodic water and electrolytic anodic water.
Although the electrolyzed water production apparatus itself is known (for example, see Patent Documents 1 and 2), the electrolyzed water production apparatus 3 used in the present invention is an artificial dialysis water production apparatus for personal dialysis for one or two persons. This is a suitable structure.
The electrolyzed water production apparatus 3 may be an apparatus in which the electrolyzed water production apparatus, the water softener 1, the adsorption device 2, and the RO device are integrated.

本発明で使用することができる電解水製造装置３を図２により説明する。
電解水製造装置３は、電気分解槽３１内にライン１３から送られた前処理水が満たされており、その中に浸漬された状態で、陰極３２が４枚と陽極３３が３枚（合計７枚）が交互に、かつ両端部側が陰極３２になるように配置されている。
また、一定回数もしくは一定時間使用ごとに電極板の極性を反転して、前記の一定回数もしくは一定時間の運転中に電解陰極水側の電極に付着したスケールを電解陽極水側に排出させることもできる。
隣接する陰極３２と陽極３３の間隔は均等間隔であり、かつ３〜５ｍｍの範囲、好ましくは３〜４．５ｍｍの範囲である。
陰極３２と陽極３３の間には隔膜３４が、陰極３２と陽極３３の間を等分に区切るように配置されており、陰極３２が配置された陰極槽４１〜４３、６２と陽極３３が配置された陽極槽５１、５２、６１に分離されている。
なお、陰極と陽極の間と陽極と陰極の間にて電解が生じるため、図２では、７枚の電極で挟まれた合計６のゾーン（電解槽）で電解が生じることになる。６つの電解槽はそれぞれ隔膜３４で２つに仕切られているので、６つの電解槽は６つの陰極セルと６つの陽極セルからなっている。 An electrolyzed water production apparatus 3 that can be used in the present invention will be described with reference to FIG.
In the electrolyzed water production apparatus 3, the pretreatment water sent from the line 13 is filled in the electrolysis tank 31, and four cathodes 32 and three anodes 33 (total) are immersed in the electrolysis water 31. 7 sheets) are alternately arranged and both end portions are arranged to be the cathodes 32.
In addition, the polarity of the electrode plate is reversed every use for a certain number of times or for a certain period of time, and the scale adhering to the electrode on the electrolytic cathodic water side during the operation for a certain number of times or for a certain time can be discharged to the electrolytic anodic water side. it can.
The interval between the adjacent cathode 32 and the anode 33 is a uniform interval and is in the range of 3 to 5 mm, preferably in the range of 3 to 4.5 mm.
A diaphragm 34 is disposed between the cathode 32 and the anode 33 so as to equally divide the cathode 32 and the anode 33, and the cathode tanks 41 to 43 and 62 in which the cathode 32 is disposed and the anode 33 are disposed. The anode tanks 51, 52 and 61 are separated.
Since electrolysis occurs between the cathode and the anode and between the anode and the cathode, in FIG. 2, electrolysis occurs in a total of six zones (electrolyzers) sandwiched between seven electrodes. Since each of the six electrolytic cells is divided into two by the diaphragm 34, the six electrolytic cells are composed of six cathode cells and six anode cells.

電極板（陰極と陽極）の大きさは、電解水製造装置３の大きさに合わせて調整する。本発明の人工透析用水製造装置は個人透析用であり、２５〜８０Ｌ／ｈｒ量（一人用または二人用として好適な量）の透析用水が調製されれば流量的には十分であるため、電極板も医療施設で一般的に使用されている電解水製造装置と比べると小型になる。
図２では陰極３２と陽極３３が合計で７枚であるが、８枚以上の枚数にすることもできる。前記の通り、本発明の電解装置で調製される必要水量が小さいため、水素を発生させる陰極槽における電解条件（電流密度、槽内の滞留時間）も、電極板面積、陰極槽内流量に応じて、適宜、設定される。 The size of the electrode plates (cathode and anode) is adjusted according to the size of the electrolyzed water production apparatus 3. The artificial dialysis water production apparatus of the present invention is for personal dialysis, and if dialysis water of 25 to 80 L / hr (a suitable amount for one person or two persons) is prepared, the flow rate is sufficient. The electrode plate is also smaller than the electrolyzed water production apparatus generally used in medical facilities.
In FIG. 2, the total number of the cathode 32 and the anode 33 is seven, but the number may be eight or more. As described above, since the required amount of water prepared by the electrolysis apparatus of the present invention is small, the electrolysis conditions (current density, residence time in the cell) in the cathode cell for generating hydrogen also depend on the electrode plate area and the flow rate in the cathode cell. Is set as appropriate.

電解水製造装置３の運転により陰極槽４１〜４３、６２では、溶存水素濃度の高い電解陰極水が得られ、陽極槽５１、５２、６１では、相対的に溶存水素濃度の低い電解陽極水が得られる。
電解陰極水量と電解陽極水量の生成量は、電解陰極水量の方が多くなるようにすることが望ましく、例えば電解陰極水量：電解陽極水量＝４〜６：１にすることができる。
電解陰極水は、ポンプ２２を駆動させてライン１４からＲＯ装置４に送られ、電解陽極水はライン１５から排出される。
なお、電解水製造装置３とポンプ２２の間に電解陰極水を貯水するための電解陰極水タンクを設置して、電解陰極水タンクに貯水した電解陰極水をＲＯ装置４に送るようにすることもできる。 By operation of the electrolyzed water production apparatus 3, electrolytic cathode water having a high dissolved hydrogen concentration is obtained in the cathode tanks 41 to 43, 62, and electrolytic anode water having a relatively low dissolved hydrogen concentration is obtained in the anode tanks 51, 52, 61. can get.
It is desirable that the amount of electrolytic cathodic water and electrolytic anodic water be larger than the amount of electrolytic cathodic water, for example, the amount of electrolytic cathodic water: electrolytic anodic water = 4 to 6: 1.
The electrolytic cathodic water is sent to the RO device 4 from the line 14 by driving the pump 22, and the electrolytic cathodic water is discharged from the line 15.
An electrolytic cathodic water tank for storing electrolytic cathodic water is installed between the electrolyzed water production apparatus 3 and the pump 22 so that the electrolytic cathodic water stored in the electrolytic cathodic water tank is sent to the RO device 4. You can also.

ＲＯ装置４は公知のものを用いることができ、例えば、ダイセン・メンブレン・システムズ株式会社より販売されている、装置型式ＶＣＲ２０シリーズ、を用いることができる。   As the RO device 4, a known device can be used. For example, the device type VCR20 series sold by Daisen Membrane Systems Co., Ltd. can be used.

ＲＯ装置４で得られた透過水は、ライン１６から透過水タンク（ＲＯ水タンク）５に送られて貯水される。
個人透析による人工透析は、多人数透析と比べると使用頻度が低く、ＲＯ装置の停止期間が長くなり、外部からの菌汚染を生じる可能性があるため、必要に応じてＲＯ装置４の出口にＵＦ膜モジュール（ＵＦ装置）を設けて、ＵＦ膜処透過水をＲＯ水タンク（人工透析液用水タンク）５に貯水することもできる。
ＲＯ装置４では、溶存水素濃度の高い電解陰極水を処理しているため、ＲＯ水中の溶存水素濃度も高くなっており、一方、残存するイオン成分がさらに除去されており、電気伝導度は１〜２０μＳ程度にまで低下されている。
ＲＯ水タンク５内のＲＯ水は、ライン１７から採水されて人工透析液用水として使用される。
ＲＯ装置３で得られた濃縮水は、ライン１８から電解水製造装置３に送られて再度電気分解処理してもよいし、ライン１９から排出されるようにしてもよい。 The permeated water obtained by the RO device 4 is sent from the line 16 to the permeated water tank (RO water tank) 5 and stored therein.
Artificial dialysis by personal dialysis is less frequently used than multi-person dialysis, and the stop period of the RO device becomes longer and may cause bacterial contamination from the outside. A UF membrane module (UF device) may be provided, and the UF membrane treated permeated water may be stored in the RO water tank (artificial dialysate water tank) 5.
In the RO device 4, since the electrolytic cathodic water having a high dissolved hydrogen concentration is treated, the dissolved hydrogen concentration in the RO water is also high, while the remaining ionic components are further removed, and the electric conductivity is 1 It is lowered to about 20 μS.
The RO water in the RO water tank 5 is collected from the line 17 and used as artificial dialysate water.
The concentrated water obtained by the RO device 3 may be sent from the line 18 to the electrolyzed water production device 3 and may be electrolyzed again, or may be discharged from the line 19.

図１に示す製造装置は、適宜清浄水で通水洗浄することができるほか、ＲＯ装置４、タンク５および各ラインは、過酢酸水溶液等の殺菌剤で殺菌・洗浄することもできる。また、電解水製造装置３を除く前記装置類・各ラインは加熱殺菌することができる。さらに、タンク５には、ＵＶ殺菌灯を設けてもよい。 Each line of the manufacturing apparatus shown in FIG. 1 can be provided with an on-off valve, a flow meter, a thermometer, or the like made up of an electromagnetic valve or the like as necessary.
The manufacturing apparatus shown in FIG. 1 can be appropriately washed with clean water, and the RO apparatus 4, the tank 5 and each line can be sterilized and washed with a sterilizing agent such as an aqueous peracetic acid solution. Moreover, the said apparatuses and each line except the electrolyzed water manufacturing apparatus 3 can be heat-sterilized. Further, the tank 5 may be provided with a UV germicidal lamp.

図３により本発明の製造装置の好ましい実施形態を説明する。
本発明の製造装置は、個人透析用の人工透析用水製造装置であることから、狭いスペースに設置することが多くなる。
図３は、本発明の製造装置を個人用としてより使い易いようにまとめた好ましい実施形態を示している。
個人透析用の人工透析用水製造装置１０は、金属製乃至は合成樹脂製の外側ケース１１内に、原水源（例えば、水道管）と接続された軟水装置１、吸着装置２、電解水製造装置３、電解陰極水タンク１２、ＲＯ装置４、ＵＦ装置１３が配置され、原水ポンプ２１、ＲＯポンプ２２が配置されている。
ＲＯ水タンク（人工透析液用水タンク）５は、ケース１１の外側にケース１１と一体にかつ着脱自在に設置されている。
破線で示した吸着装置２とＲＯポンプ２２は、反対側に配置されていることを示している。
図３で示す人工透析用水製造装置１０は、個人透析用としての十分な製造能力を維持したままで、縦幅３００〜５００ｍｍ、横幅９００〜１１００ｍｍｍ、高さが９５０〜１２００ｍｍ程度の大きさにすることができる。 A preferred embodiment of the production apparatus of the present invention will be described with reference to FIG.
Since the production apparatus of the present invention is an artificial dialysis water production apparatus for personal dialysis, it is often installed in a narrow space.
FIG. 3 shows a preferred embodiment in which the manufacturing apparatus of the present invention is summarized for easier use for personal use.
An artificial dialysis water production apparatus 10 for personal dialysis includes an outer case 11 made of metal or synthetic resin, a soft water apparatus 1, an adsorber 2, and an electrolyzed water production apparatus connected to a raw water source (for example, a water pipe). 3, the electrolytic cathode water tank 12, the RO device 4, and the UF device 13 are disposed, and the raw water pump 21 and the RO pump 22 are disposed.
The RO water tank (artificial dialysate water tank) 5 is installed outside the case 11 integrally with the case 11 and is detachable.
The adsorbing device 2 and the RO pump 22 indicated by broken lines indicate that they are arranged on the opposite side.
The water production apparatus 10 for artificial dialysis shown in FIG. 3 has a vertical width of 300 to 500 mm, a horizontal width of 900 to 1100 mm, and a height of about 950 to 1200 mm while maintaining a sufficient production capacity for personal dialysis. be able to.

本発明の製造装置は医療施設の個別透析や、家庭での在宅透析に使用できるものであるが、地域によっては原水となる水道水や地下水の電気伝導度が異なる場合がある。
本発明の製造装置で使用する電解水製造装置３は、電極枚数が７枚以上と多く、電極間の距離が小さいことから、電気伝導度が低い原水でも使用することができ、例えば、電気伝導度が４０〜１００μＳ／ｃｍと１００μＳ／ｃｍ以下の低電導度の原水でも、十分な濃度の溶存水素を含む電解陰極水を製造することができる。
また、電解電圧を７０Ｖまで高めること、電極枚数を増やすことで陰極槽数を増やし、陰極槽当たりの供給流量を相対的に少なくすることにより陰極槽内滞留時間を長くして、より電解効率を高め、低電導度の原水でも溶存水素量を増やすことができる。
本発明の電解装置においては、電解電圧を高めることにより、電流密度は、０．５Ａ／dm2〜２．０Ａ／dm2、好ましくは０．６Ａ／dm2〜１．５Ａ／dm2の範囲を設定でき、また、陰極槽内滞留時間を０．４〜２．３秒、好ましくは１〜２秒の範囲で設定することにより、効率よく高濃度の溶存水素水を製造することができる。 The production apparatus of the present invention can be used for individual dialysis in a medical facility or home dialysis at home, but the electric conductivity of tap water or groundwater as raw water may vary depending on the region.
The electrolyzed water production apparatus 3 used in the production apparatus of the present invention has a large number of electrodes of 7 or more, and since the distance between the electrodes is small, it can be used even in raw water with low electrical conductivity. Electrolytic cathodic water containing a sufficient concentration of dissolved hydrogen can be produced even with low conductivity raw water having a degree of 40 to 100 μS / cm and 100 μS / cm or less.
Also, increasing the electrolysis voltage to 70V, increasing the number of electrodes, increasing the number of cathode cells, and relatively reducing the supply flow rate per cathode cell, thereby prolonging the residence time in the cathode cell and further increasing the electrolysis efficiency. It is possible to increase the amount of dissolved hydrogen even in raw water with high conductivity and low conductivity.
In the electrolysis apparatus of the present invention, by increasing the electrolysis voltage, the current density can be set in the range of 0.5 A / dm 2 to 2.0 A / dm 2, preferably 0.6 A / dm 2 to 1.5 A / dm 2, In addition, by setting the residence time in the cathode chamber in the range of 0.4 to 2.3 seconds, preferably 1 to 2 seconds, high-concentration dissolved hydrogen water can be produced efficiently.

本発明の製造装置は、原水として家庭の水道水や地下水を使用した場合、さらに上記した電気伝導度の低い原水を使用した場合においても、溶存水素濃度が１００〜１６００ppbの人工透析用水を２５〜８０Ｌ／ｈｒ量（一人用または二人用として好適な量）製造することができる。
また、本発明の電解効率の高い電解装置を適用し、軟水器、活性炭、逆浸透膜装置と一体化することにより、本発明の透析用水製造装置全体が個人透析用に適応した小型装置として、製作することが可能となる。 In the production apparatus of the present invention, when domestic tap water or groundwater is used as raw water, and even when the above-described raw water with low electrical conductivity is used, 25 to 25 water for artificial dialysis having a dissolved hydrogen concentration of 100 to 1600 ppb is used. An amount of 80 L / hr (a quantity suitable for one person or two persons) can be produced.
In addition, by applying the electrolyzer with high electrolysis efficiency of the present invention and integrating it with a water softener, activated carbon, and reverse osmosis membrane device, the entire dialysis water production apparatus of the present invention is adapted for personal dialysis, It becomes possible to produce.

本発明の製造装置により得られた溶存水素濃度の高い人工透析用水と必要成分を混合して得られた人工透析液は、抗酸化作用が高く、活性酸素種に対して抗酸化作用（還元作用）を発揮することで、人工透析患者に好ましい影響を与えることが期待される。   Artificial dialysate obtained by mixing artificial dialysis water with a high dissolved hydrogen concentration obtained by the production apparatus of the present invention and necessary components has high antioxidant action and has antioxidative action (reducing action) against active oxygen species. ) Is expected to have a positive effect on dialysis patients.

（参考例）
実施例１〜６の電解水製造装置における印加電流密度と陰極槽における滞留時間を求めた。
１．電流密度の計算
1)電極面積は、電極の横幅６９ｍｍ（0.69dm）と高さ１１０ｍｍ（1.1dm）から、
０．６９dm×１．１dm＝０．７５９dm2となる。
2)電解電流
・実施例１、３、５、６の場合は電解電流５Ａである。図２における7枚の電極によって仕切られた電解槽は６槽であり、各電解槽あたりの印可電流は、全電解電流／電解槽数で求められる。
よって、５A／６槽＝０．８３Ａ／槽となる。
・実施例２、４の場合は電解電流３．５Ａである。
よって、３．５A／６槽＝０．５８Ａ／槽となる。
3)電流密度は、電解槽当たり電流値／電極面積で求められる。
・実施例１、３、５、６の場合は、０．８３／０．７５９＝１．１Ａ／dm2となる。
・実施例２、４の場合は、０．５８／０．７５９＝０．７Ａ／dm2となる。 (Reference example)
The applied current density in the electrolyzed water production apparatuses of Examples 1 to 6 and the residence time in the cathode chamber were determined.
1. Calculation of current density
1) The electrode area is 69 mm (0.69 dm) in width and 110 mm (1.1 dm) in height.
0.69 dm × 1.1 dm = 0.759 dm 2 .
2) Electrolytic current-In the case of Examples 1, 3, 5, and 6, the electrolytic current is 5A. The number of electrolytic cells partitioned by the seven electrodes in FIG. 2 is 6, and the applied current per electrolytic cell is obtained by the total electrolytic current / the number of electrolytic cells.
Therefore, 5A / 6 tank = 0.83A / tank.
In the case of Examples 2 and 4, the electrolytic current is 3.5 A.
Therefore, 3.5 A / 6 tank = 0.58 A / tank.
3) The current density is determined by the current value per electrolytic cell / electrode area.
In the case of Examples 1, 3, 5, and 6, 0.83 / 0.759 = 1.1 A / dm 2 is obtained.
In the case of Examples 2 and 4, 0.58 / 0.759 = 0.7 A / dm 2 .

２．滞留時間の算出
１）陰極槽の容積
図２の通り、電解装置は陰極３２と陽極３３が隔膜３４で等分に区切られて陰極槽と陽極槽を形成しており、それぞれの電極間距離は３．５mmでそれが等分に区切られた陰極槽、陽極槽を形成しているので、陰極槽の全容積と陽極槽の全容積は等しくなる。
電極槽は陰極槽と陽極槽を合わせて６槽あるので、陰極槽全体としては全電極槽容積の１／２（３槽分）となる。
従って、陰極槽全体容積は、６．９cm（電極高さ）×１１．０cm（電極幅）×０．３５cm（陰極槽厚み）×３（槽）＝７０．６９５cm3と計算される。
２）各実施例の陰極槽供給流量は次のように計算される。
実施例1〜４：全体供給水量３．８Ｌ／分＝５２．７７８ｍｌ／秒
５２．７７８ｍｌ／秒×５／６＝４３．９８ｍｌ／秒
実施例５：全体供給水量４．５Ｌ／分＝７５ｍｌ／秒
７５ｍｌ／秒×５／６＝６２．５ｍｌ／秒
実施例６：全体供給水量４．６Ｌ／分＝７６．６６７ｍｌ／秒
７６．６６７ｍｌ／秒×５／６＝６３．８９ｍｌ／秒
３）前記の陰極槽供給流量と陰極槽容積から陰極槽内滞留時間は下記の通りに計算される。
＜滞留時間＞
実施例１〜４：７９．６９５cm3／４３．９８ml/sec＝１．８１秒
実施例５：７９．６９５cm3／６２．５ml/sec＝１．２８秒
実施例６：７９．６９５cm3／６３．８９ml/sec＝１．２５秒 2. Calculation of residence time 1) Volume of cathode chamber As shown in FIG. 2, the electrolysis apparatus has a cathode chamber and an anode chamber that are divided equally between a cathode 32 and an anode 33 by a diaphragm 34. Since the cathode cell and the anode cell, which are equally divided at 3.5 mm, are formed, the total volume of the cathode cell is equal to the total volume of the anode cell.
Since there are six electrode tanks in total including the cathode tank and the anode tank, the entire cathode tank is ½ of the total electrode tank volume (for three tanks).
Therefore, the total volume of the cathode cell is calculated as 6.9 cm (electrode height) × 11.0 cm (electrode width) × 0.35 cm (cathode cell thickness) × 3 (cell) = 70.695 cm 3 .
2) The cathode cell supply flow rate in each example is calculated as follows.
Examples 1-4: Total water supply amount 3.8 L / min = 52.778 ml / sec
52.778 ml / sec × 5/6 = 43.98 ml / sec Example 5: Total water supply amount 4.5 L / min = 75 ml / sec
75 ml / sec × 5/6 = 62.5 ml / sec Example 6: Total water supply amount 4.6 L / min = 76.667 ml / sec
76.667 ml / sec × 5/6 = 63.89 ml / sec 3) From the cathode cell supply flow rate and the cathode cell volume, the residence time in the cathode cell is calculated as follows.
<Residence time>
Example 1~4: 79.695cm 3 /43.98ml/sec=1.81 seconds Example 5: 79.695cm 3 /62.5ml/sec=1.28 seconds Example 6: 79.695cm 3/63 .89ml / sec = 1.25 seconds
