Description

発明の詳細な説明Detailed Description of the Invention
本発明は塩素イオン溶液を電気分解し次亜塩素酸水を生成する装置に関する  The present invention relates to an apparatus for electrolyzing a chlorine ion solution to generate hypochlorous acid water.
食塩、塩化カリウム、塩酸などの溶液のように塩素イオンを含んだ溶液を直流電流で電気分解し次亜塩素酸水を作る技術は以前から行われている。
いずれも塩素イオン(Cl)が陽極表面で電解酸化を受けて塩素(Cl)となり、さらに水と反応し、次の反応式のように次亜塩素酸を生成することを利用したものである。
Cl + HO → HOCl + HCl
それらの装置には、食塩や塩化カリウムの低濃度溶液を隔膜式電解槽で電解する装置で、特許文献1に記載されている装置や、高濃度の塩溶液を連続的に電解し、原水で希釈調製する装置で、特許文献2に記載されている装置、あるいは高濃度の原液を貯留した電解槽を水タンク内に投入して電解し、電解槽内部に生成した電解液をタンク内に混合希釈する装置で、特許文献3に記載された装置などが知られている。
しかし、連続的に生成する装置にあっては連続的に給水する設備と、装置に必要な給水量、給水圧が必要でそのような給水設備のある場所でしか使用できなかった。また、電極は常に電解液に浸漬された状態になるので電極寿命が短かった。一方、回分式の生成装置にあっては連続生成はできないため使用目的や使用方法に制限があった。
一方また、低濃度に希釈した塩素イオン溶液を電解する方式にあっては、能力を大きくするには相対的に電解槽が大型化する傾向があり、価格も高価であった。

Techniques for producing hypochlorous acid water by electrolyzing a solution containing chlorine ions such as a solution of sodium chloride, potassium chloride, hydrochloric acid, etc. with a direct current have been performed.
In both cases, chlorine ions (Cl ) are subjected to electrolytic oxidation on the anode surface to become chlorine (Cl 2 ), and further react with water to generate hypochlorous acid as in the following reaction formula. is there.
Cl 2 + H 2 O → HOCl + HCl
These devices include a device that electrolyzes a low-concentration solution of sodium chloride or potassium chloride in a diaphragm-type electrolytic cell, a device described in Patent Document 1, or a device that continuously electrolyzes a high-concentration salt solution and uses raw water. A device for dilution preparation. The device described in Patent Document 2 or an electrolytic cell storing a high concentration stock solution is introduced into a water tank for electrolysis, and the electrolytic solution generated inside the electrolytic cell is mixed in the tank. As an apparatus for diluting, an apparatus described in Patent Document 3 is known.
However, an apparatus that continuously generates water is required to be used only in a place where such a water supply facility is required because it requires a facility for continuously supplying water, a water supply amount and a water supply pressure necessary for the device. Moreover, since the electrode was always immersed in the electrolyte, the electrode life was short. On the other hand, since a batch-type production apparatus cannot perform continuous production, there are limitations on the purpose of use and method of use.
On the other hand, in the method of electrolyzing a chlorine ion solution diluted to a low concentration, the electrolytic cell has a tendency to be relatively large in order to increase the capacity, and the price is also expensive.

The best mode for carrying out the present invention is an intermittent automatic electrolytic hypochlorous acid water generator having the following components and functions. That is, a storage-type electrolytic cell is provided, a means for supplying a chlorine ion solution to the electrolytic cell prior to electrolysis, and a means for mixing and diluting the electrolytic product with raw water after electrolysis, to the electrolytic cell for the chlorine ion solution prior to electrolysis This is a mechanism in which operations such as feeding, electrolysis, and mixing and dilution of the electrolysis product after electrolysis to raw water are automatically continued in this order. Mixing dilution of the electrolytic product into the raw water is appropriately combined with injecting the electrolytic product into the raw water separately stored in the storage means (hereinafter referred to as storage means A) and returning the raw water to the electrolytic cell. Finally, all the liquid in the electrolytic cell is united with the raw water stored in the storage means A to become hypochlorous acid water. Furthermore, in addition to the storage means A, a storage means (hereinafter referred to as storage means B) is provided, and the storage means B is a means for receiving and storing hypochlorous acid water generated and stored in the storage means A. It becomes a storage means for hypochlorous acid water supply. As for the transfer of hypochlorous acid water from the storage means A to the storage means B, the combined dilution with the raw water stored in the storage means A for electrolytic products and the union of the total amount are completed, and the hypochlorite is stored in the storage means A. Let it be a mechanism performed on condition that acid water is stored and the water level of storage means B is below a fixed level.
Furthermore, as the best embodiment, the electrolytic cell is a diaphragm type electrolytic cell, the chloride ion solution is a hydrochloric acid solution having a concentration of 0.1 to 0.6 molar, and a certain amount of hydrochloric acid solution It is a structure in which the supply to the electrolytic cell is performed by an automatic weighing tank.
Further, in order to deepen the understanding of the present invention, the present invention will be described in detail with reference to examples, but the scope of the present invention is not intended to be limited to these examples.
本発明を図1に基づいて説明する。(3)は原料塩酸を貯留する容器(200ml)、(2)は原料塩酸を自動的に一定量秤取する自動秤量升((株)ホクエツ製、分取量15ml)、(9)は秤取された原料塩酸を電解槽(1)((株)ホクエツ製)に移送する配管である。まず、自動秤量升の秤量部が回転し開口部が原料塩酸の貯留タンクに繋がる配管側に向くと、貯留タンクから原料塩酸が流下し秤量部に溜まる。次に秤量部が回転し、開口部が電解槽側の配管(9)に向くと、秤量された塩酸は配管(9)を経て電解槽に注入される仕組みになっている。その時、貯留タンク側の配管には秤量部の底が向いており閉塞されている。これが電解に先立ち塩素イオン溶液を電解槽へ供給する動作である。
続いて電解動作が始まる。電解槽に一定電圧をかけ、一定時間電解し終了する。その間、塩酸供給側配管は計量升で閉塞されているので逆流は阻止されている。一方、送水ポンプ(5)(ヘンミ計算尺製、ダイヤフラムポンプ)に繋がる配管(10)は送水ポンプによって閉塞されている。従って電解中に発生したガス等は貯留手段A(4)(樹脂製タンク、容量5L)に繋がる配管(10)を経て貯留手段A中に貯留された原水中に注入される。この状態で電解終了まで維持される。続いて電解生成物の原水への混合希釈が始まる。まず、送水ポンプが貯留手段Aから、予め貯留されている原水(5L)を電解槽の方向に10分間、100ml/分の流速で流す。これにより電解槽中に貯留していた電解生成物は配管(10)を経て貯留手段Aに洗い込まれる。その後、送液ポンプは逆に電解槽から貯留手段Aに向かって1分間液を流す。この間、配管(10)は貯留手段Aからの吸引圧よりも、配管(10)の途中に設置された逆止弁(6)からの吸引圧が低くなっているため、貯留手段Aから液体を吸い上げることはなく、代わりに逆止弁から外気を吸入する。これによって電解槽に貯留していた液は全て貯留手段Aに回収混合される。この動作で電解生成物は原水に混合希釈され、貯留手段Aには目的の次亜塩素酸水が生成される。
続いてバルブ7が開き、貯留手段Aに貯留されている次亜塩素酸水は貯留手段B(8)に移され、そこから各種の使用に供される。貯留手段Aには原水バルブ(13)から次回の原水が供給される。
以上の一連の動作を繰り返すことにより、貯留手段Bから連続的に外部への次亜塩素酸水の供給が行われた。
この装置を使い0.3モル濃度の塩酸を使用し、自動運転を行った結果、貯留手段Bからは、有効塩素濃度15ppm、pH6.0の次亜塩素酸水を毎分2Lで連続的に取り出すことができ、又間歇的には1分毎に2L使用することができた。
The present invention will be described with reference to FIG. (3) is a container (200 ml) for storing raw hydrochloric acid, (2) is an automatic weighing bowl (manufactured by Hokuetsu Co., Ltd., 15 ml), and (9) is a weighing machine. It is piping which transfers the taken raw material hydrochloric acid to the electrolytic cell (1) (made by Hokuetsu Co., Ltd.). First, when the weighing section of the automatic weighing basket is rotated and the opening faces the pipe connected to the raw hydrochloric acid storage tank, the raw hydrochloric acid flows down from the storage tank and accumulates in the weighing section. Next, when the weighing section rotates and the opening faces the pipe (9) on the electrolytic cell side, the weighed hydrochloric acid is injected into the electrolytic cell through the pipe (9). At that time, the bottom of the weighing unit faces the piping on the storage tank side and is closed. This is the operation of supplying a chlorine ion solution to the electrolytic cell prior to electrolysis.
Subsequently, the electrolysis operation starts. A constant voltage is applied to the electrolytic cell and electrolysis is completed for a certain time. In the meantime, the hydrochloric acid supply side pipe is blocked with a measuring rod, so that backflow is prevented. On the other hand, the pipe (10) connected to the water pump (5) (made by Henmi Kosakusha, diaphragm pump) is closed by the water pump. Therefore, gas generated during electrolysis is injected into the raw water stored in the storage means A through the pipe (10) connected to the storage means A (4) (resin tank, capacity 5L). This state is maintained until the end of electrolysis. Subsequently, the mixed dilution of the electrolytic product into the raw water begins. First, the water pump feeds raw water (5 L) stored in advance from the storage means A in the direction of the electrolytic cell for 10 minutes at a flow rate of 100 ml / min. Thereby, the electrolytic product stored in the electrolytic cell is washed into the storage means A through the pipe (10). Thereafter, the liquid feed pump flows the liquid from the electrolytic cell toward the storage means A for 1 minute. During this time, since the suction pressure from the check valve (6) installed in the middle of the pipe (10) is lower than the suction pressure from the storage means A, the pipe (10) has a liquid from the storage means A. Instead of sucking up, inhale outside air from the check valve instead. As a result, all the liquid stored in the electrolytic cell is collected and mixed in the storage means A. By this operation, the electrolytic product is mixed and diluted with raw water, and the target hypochlorous acid water is generated in the storage means A.
Subsequently, the valve 7 is opened, and the hypochlorous acid water stored in the storage means A is transferred to the storage means B (8), from which it is used for various uses. The next raw water is supplied to the storage means A from the raw water valve (13).
By repeating the above series of operations, hypochlorous acid water was continuously supplied from the storage means B to the outside.
As a result of automatic operation using 0.3 mol hydrochloric acid using this apparatus, the storage means B continuously supplied hypochlorous acid water having an effective chlorine concentration of 15 ppm and pH 6.0 at a rate of 2 L / min. It was possible to take out, and intermittently, 2 L could be used every minute.
