Description

本発明は、電解槽の殺菌及びカルシウム付着の除去方法に関するものである。   The present invention relates to a method for sterilizing an electrolytic cell and removing calcium adhesion.

公知の伝統的な電解槽には、殺菌ができないこと、及び陰極板にカルシウムが付着しやすい問題が存在する。殺菌の問題は、一般に紫外線ライト管もしくは極小孔のフィルターを使用して殺菌もしくは菌を除去する。また、カルシウム付着問題は、反極性の電圧をかけてカルシウムを除去するか、もしくは食用のレモン酸もしくは酢酸で洗浄する。   Known traditional electrolyzers have the problem that they cannot be sterilized and that calcium tends to adhere to the cathode plate. The problem of sterilization is generally sterilization or removal of bacteria by using a UV light tube or a microporous filter. In addition, the calcium adhesion problem is to remove calcium by applying a reverse polarity voltage, or to wash with edible lemon acid or acetic acid.

しかしながら、紫外線ライト管の殺菌もしくは如何なるフィルター材でも実施にはコストがかかり、経済効率が低い。また反極性電圧をかけると、アルカリ水が流れる管の水が酸性水に変化してしまい、反対に酸性水が流れる管の水はアルカリ水に変化してしまう。このため水流交換バルブを追加することにより、元アルカリ水道をアルカリ水に維持しなければならない。ただ、上述の方法は、水流交換バルブを設置するのに、一定の空間を要し、且つコストも上がる。もしくは残留水逆酸で洗うことを採用すると、水が流れなくなるため、採用されない。また漬け込み方式を採用すると、同様に使用上不便であり、改善が求められる。   However, sterilization of UV light tubes or any filter material is costly to implement and is not economical. When a reverse polarity voltage is applied, the water in the pipe through which the alkaline water flows changes to acidic water, and conversely, the water in the pipe through which the acidic water flows changes to alkaline water. For this reason, the original alkaline water supply must be maintained in alkaline water by adding a water flow exchange valve. However, the above-described method requires a certain space to install the water flow exchange valve and increases the cost. Alternatively, if washing with residual water reverse acid is adopted, water will not flow, so it is not adopted. In addition, the use of the soaking method is similarly inconvenient in use and requires improvement.

公知の電解水用電解槽に既存する問題を解決し、電解槽の殺菌及びカルシウム付着の除去方法を提供する。電解過程中、電解槽内に実際の電解作業より数倍以上高い瞬間相反極性パルス波をかけ、パルス波電圧によって細菌や病原菌を死滅させ、同時に振動が陰極板上の炭酸カルシウム(CaCo3)もしくはその他結合型カルシウム付着を除去し、陰極板の結晶の沈殿を防止する。   The present invention solves the problems existing in known electrolyzers for electrolyzed water, and provides a method for sterilizing electrolyzers and removing calcium adhesion. During the electrolysis process, an instantaneous reciprocal pulse wave that is several times higher than the actual electrolysis operation is applied to the electrolytic cell, and bacteria and pathogens are killed by the pulse wave voltage. At the same time, the vibration is calcium carbonate (CaCo3) on the cathode plate or other Removes bound calcium adhesion and prevents precipitation of cathode plate crystals.

請求項1の発明は、電解槽の殺菌及びカルシウム付着の除去方法において、主に電解過程中、電解槽内で実際電解作業より高い電圧の瞬間パルス波をかけ、そのパルス波の電圧の大きさは、陰陽極板の隙間と水の菌含有量及び水の硬度に基づいて決めることを特徴とする電解槽の殺菌及びカルシウム付着の除去方法としている。
請求項2の発明は、請求項1記載の電解槽の殺菌及びカルシウム付着の除去方法において、前記瞬間パルス波電圧は、その極性と実際電解作業が相反することを特徴とする電解槽の殺菌及びカルシウム付着の除去方法としている。
請求項3の発明は、請求項1記載の電解槽の殺菌及びカルシウム付着の除去方法において、前記パルス波は、その振動数が実際の出水量によって電解槽の実際容量が最小振動数であることを特徴とする電解槽の殺菌及びカルシウム付着の除去方法としている。
According to the first aspect of the present invention, in the method of sterilizing an electrolytic cell and removing calcium adhesion, an instantaneous pulse wave having a higher voltage than that of actual electrolysis is applied in the electrolytic cell mainly during the electrolysis process, and the magnitude of the voltage of the pulse wave is applied. Is a method of sterilizing an electrolytic cell and removing calcium adhesion, characterized by being determined based on the gap between the negative and positive electrode plates, the microbial content of water and the hardness of water.
According to a second aspect of the present invention, in the method for sterilizing an electrolytic cell and removing calcium adhesion according to the first aspect, the instantaneous pulse wave voltage has a contradiction between the polarity and the actual electrolysis operation. It is a method for removing calcium adhesion.
According to a third aspect of the present invention, in the method for sterilizing an electrolytic cell and removing calcium adhesion according to the first aspect, the pulse wave has an actual capacity of the electrolytic cell having a minimum frequency depending on an actual amount of water discharged. This is a method for sterilizing an electrolytic cell and removing calcium adhesion.

電解槽の殺菌及びカルシウム付着の除去方法は、電解槽の電解過程中、電解槽内で実際の電解作業より数倍以上高い瞬間相反パルス波をかける。このパルス波の電圧は細菌や病原菌を死滅させ、同時に振動により陰極板上の炭酸カルシウム(CaCo3)もしくはその他の結合型カルシウム付着を除去し、結晶を沈殿させない。   The electrolytic cell sterilization and calcium adhesion removal method applies an instantaneous reciprocal pulse wave several times higher than actual electrolytic work in the electrolytic cell during the electrolytic process of the electrolytic cell. The voltage of this pulse wave kills bacteria and pathogens, and at the same time, removes calcium carbonate (CaCo3) or other bound calcium adhesion on the cathode plate by vibration, and does not precipitate crystals.

電解槽の殺菌及びカルシウム付着の除去方法として、図1に示すとおり、主に電解槽(electroanalysis circuit)Aに一般の電圧をかけ、同時に電子型快速スイッチ(electronic instant switch)Cを使用して電解回路(electroanalysis circuit)A(図2に示す本発明の電解回路表示図参照)、もしくは高圧回路(high voltage pulse circuit)B(図3に示す本発明の高圧回路表示図参照)を選択する。電子型快速スイッチ(electronic instant switch)Cが電解回路Aを選択した場合、電解回路Aはオンの状態になり、また高圧回路Bはオフの状態になる。反対に電子型快速スイッチCが高圧回路Bを選択した場合、高圧回路Bはオンの状態になり、電解回路Aはオフの状態になる。   As shown in FIG. 1, as a method for sterilization of an electrolytic cell and removal of calcium adhesion, a general voltage is mainly applied to the electrolytic cell A, and at the same time, electrolysis using an electronic fast switch (electron instant switch) C is performed. A circuit (electroanalysis circuit) A (refer to the electrolytic circuit display diagram of the present invention shown in FIG. 2) or a high voltage circuit C (see the high voltage circuit display diagram of the present invention shown in FIG. 3) is selected. When the electronic fast switch C selects the electrolysis circuit A, the electrolysis circuit A is turned on and the high voltage circuit B is turned off. On the contrary, when the electronic rapid switch C selects the high voltage circuit B, the high voltage circuit B is turned on and the electrolytic circuit A is turned off.

上述の各装置が組み合わさった本発明によって、電解槽の殺菌及びカルシウム付着の除去が行われる。実際の操作として、
図4,5に示すとおり、電解の過程で、定時に瞬間的に電子型快速スイッチCが動き、電解槽10内で、実際の電解作業電圧数より倍以上高いパルス波をかけ、パルス波をかけることによって、細菌や病原菌を死滅させる。そのうち、このパルス波電圧の大きさと陰陽極板の隙間と水中に含まれる菌含有量及び硬度は正比例し、このパルス波の振動回数は実際の出水量から電解槽の実際容量を除いたものを最少振動数とする。その公式は、
パルス波振動数≧実際出水量/電解槽実際容量とする。
例として、実際出水量を毎分2000ccとする。電解槽実際容量を50ccとする。パルス波最小振動数は、2000/50=40回/分。
毎分少なくとも40回のパルス波により、水中の細菌は少なくとも一回以上の電気ショックを受ける(以上実際の数は、実際の出水量と電解槽実際容量に基づく)。
According to the present invention in which the above-described apparatuses are combined, the electrolytic cell is sterilized and the calcium adhesion is removed. As an actual operation,
As shown in FIGS. 4 and 5, in the process of electrolysis, the electronic rapid switch C instantaneously moves at a fixed time, and in the electrolytic cell 10, a pulse wave higher than the actual number of electrolysis work voltages is applied. By killing, kill bacteria and pathogens. Among them, the magnitude of the pulse wave voltage and the content and hardness of the bacteria contained in the water and the gap between the anode and anode plates are directly proportional, and the number of vibrations of this pulse wave is obtained by subtracting the actual capacity of the electrolytic cell from the actual water output. Use the lowest frequency. The formula is
Pulse wave frequency ≥ actual water output / electrolyzer actual capacity.
As an example, the actual water discharge rate is 2000 cc / min. The actual electrolytic cell capacity is 50 cc. The minimum frequency of the pulse wave is 2000/50 = 40 times / minute.
At least 40 pulse waves per minute cause the bacteria in the water to receive at least one electric shock (the actual number is based on the actual water output and the actual electrolytic cell capacity).

上述の本発明に依って提供された電解槽の殺菌及びカルシウム付着の除去方法は、そのうち、瞬間パルス波電圧がカルシウム付着を除去する時、その極性と実際の電解作業は相反し、図6に示すのは本発明の電解回路とパルス波高圧回路の切換表示図である。電解過程中、その電子型快速スイッチCはCPU及び電界効果トランジスタ(Field effect transistor)制御回路によって、スピーディにスイッチを切り換え、これにより、瞬間切換及び無火花を達成し、有効に回路寿命を延ばす。   In the method of sterilization of an electrolytic cell and removal of calcium adhesion provided by the present invention described above, when the instantaneous pulse wave voltage removes calcium adhesion, the polarity and the actual electrolysis operation are contradictory. Shown is a switching display diagram of the electrolytic circuit and the pulse wave high voltage circuit of the present invention. During the electrolysis process, the electronic high-speed switch C is quickly switched by a CPU and a field effect transistor control circuit, thereby achieving instantaneous switching and no spark and effectively extending the circuit life.

図7に示すのは、本発明の電解回路で電解する時の陰陽イオン分布状態図である。また図8に示すのは、本発明の瞬間パルス波高圧が発生する時の陰陽イオン分布状態図である。電解槽10内で、実際の電解作業より数倍以上高い電圧Vaをかけた瞬間の相反極性パルス波電圧Vbは、パルス波電圧Vbによって細菌と病原菌が死滅する以外、その振動によって陰極板上に付着した炭酸カルシウム(CaCo3)もしくはその他の結合型カルシウム付着を除去し、すでに形成している炭酸カルシウム(CaCo3)もしくはその他の結合型カルシウム付着をパルス波電圧で陰極板から振り落とし、流動水で電解槽10が流れる。 FIG. 7 shows an anion / cation distribution state diagram when electrolysis is performed in the electrolytic circuit of the present invention. Further, FIG. 8 shows an anion / cation distribution state diagram when the instantaneous pulse wave high pressure of the present invention is generated. In the electrolytic cell 10, the reciprocal polarity pulse wave voltage V b at the moment when a voltage Va that is several times higher than the actual electrolysis operation is applied to the cathode due to the vibration, except that bacteria and pathogens are killed by the pulse wave voltage V b . Removing calcium carbonate (CaCo 3 ) or other bound calcium deposits deposited on the plate, shaking off the already formed calcium carbonate (CaCo 3 ) or other bound calcium deposits from the cathode plate with a pulsed voltage, The electrolytic cell 10 flows with flowing water.

上述のパルス波の電圧Vbは、実際の電解作業電圧Vaより数倍以上大きい。しかし、瞬間パルス波のバンド幅は数ミリ秒(10-3秒)であるため、発生するパルス波は平均電流Ibが実際のところ、電解回路Iaよりはるかに小さい(Ib<<Ia)ので、電解回路の正常電解に影響を与えない。また同時に発生した瞬間振動力量は、陽イオンを陰極板から剥がすだけで陰、陽イオン層の混合現象が発生するほどではない。 The pulse wave voltage V b described above is several times greater than the actual electrolysis work voltage V a . However, since the bandwidth of the instantaneous pulse wave is several milliseconds (10 −3 seconds), the generated pulse wave has an average current I b that is actually much smaller than the electrolytic circuit I a (I b << I a ) Because it does not affect the normal electrolysis of the electrolytic circuit. Further, the instantaneous vibration force generated at the same time is not so much that the cation layer mixing phenomenon occurs only by removing the cations from the cathode plate.
