도 1은 본 발명의 살균수 제조장치를 도시한 개략도1 is a schematic view showing a sterilizing water production apparatus of the present invention

이하, 본 발명의 기술적 사상을 첨부된 도면을 사용하여 더욱 구체적으로 설명한다. Hereinafter, the technical spirit of the present invention will be described in more detail with reference to the accompanying drawings.

그러나 첨부된 도면은 본 발명의 기술적 사상을 더욱 구체적으로 설명하기 위하여 도시한 일 예에 불과하므로 본 발명의 기술적 사상이 첨부된 도면의 형태에 한정되는 것은 아니다. It is to be understood, however, that the appended drawings illustrate only typical embodiments of the present invention and are not to be considered as limiting the scope of the invention.

본 발명은 차아염소산수용액 살균수를 제조하는 장치 및 방법에 관한 것이며, 염산이 아닌 염화나트륨수용액을 사용하여 차아염소산수용액 살균수를 제조하려는 목적을 갖는다.The present invention relates to an apparatus and a method for preparing sterilized aqueous hypochlorous acid solution, and has an object of preparing sterilized aqueous hypochlorous acid solution using sodium chloride solution rather than hydrochloric acid.

이를 위한 본 발명의 살균수 제조방법은, 원수와 염화나트륨을 사용하여 염화나트륨수용액을 얻는 염화나트륨수용액제조단계를 갖는다. The sterilized water production method of the present invention for this purpose, has a sodium chloride aqueous solution production step of obtaining an aqueous sodium chloride solution using raw water and sodium chloride.

또, 염화나트륨수용액제조단계에 의해 얻어진 염화나트륨수용액을 격막(31a)을 갖는 전해조(31)의 음극실(31c)과 양극실(31b)로 공급한 후 전해조(31)에서 전기분해하여 차아염소산수용액을 생성하는 전기분해단계를 갖는다.In addition, an aqueous sodium chloride solution obtained by the sodium chloride aqueous solution manufacturing step was supplied to the cathode chamber 31c and the anode chamber 31b of the electrolytic cell 31 having the diaphragm 31a, and then electrolyzed in the electrolytic cell 31 to provide an aqueous hypochlorous acid solution. Producing electrolysis step.

즉, 종래에는 염산을 전해조(31)에서 전기분해하는 방식으로 차아염소산수용액을 생산하고 있었지만 본 발명에서는 염화나트륨수용액을 전기분해하는 방식으로 차아염소산수용액을 생산하는 것이다.That is, in the past, hydrochloric acid was produced by electrolysis in the electrolytic cell 31, but in the present invention, hypochlorous acid solution was produced by electrolyzing sodium chloride solution.

차아염소산수용액을 얻기 위한 전기분해 방식은 종래와 같고, 이를 위한 전기분해수단(30)도 종래와 같은 형태 등으로 구현할 수 있으므로 이 부분에 대한 구체적인 설명은 생략한다.The electrolysis method for obtaining the hypochlorous acid solution is the same as in the prior art, and the electrolysis means 30 for this may also be embodied in the same form as in the prior art, and thus a detailed description thereof will be omitted.

전술한 설명에서 염화나트륨수용액을 제조하는 방법은 다양하게 구현 가능하다. In the above description, the method for preparing the sodium chloride solution may be variously implemented.

구체적으로 설명하면, 염화나트륨수용액제조단계는 원수가 염화나트륨저장조(10)를 경유하면서 포화염화나트륨수용액이 되도록 하는 염화나트륨수용액생성단계;Specifically, the sodium chloride aqueous solution production step is a sodium chloride aqueous solution generation step so that the raw water is a saturated sodium chloride solution while passing through the sodium chloride storage tank (10);

염화나트륨수용액생성단계에 의해 생성된 포화염화나트륨수용액과 원수를 혼합하여 희석된 염화나트륨수용액(1.5～3%정도로 희석되는 것이 바람직함)을 얻는 희석단계를 실시하는 형태로 구현될 수 있다. It can be implemented in the form of performing a dilution step to obtain a diluted sodium chloride solution (preferably diluted to about 1.5 to 3%) by mixing the saturated sodium chloride solution and raw water produced by the sodium chloride aqueous solution generation step.

그런데 본 출원의 발명자는 다양한 연구와 실험을 통해 염화나트륨수용액을 전기분해하여 얻어진 차아염소산수용액의 pH 정도에 따라 살균력에 큰 차이가 발생되는 것을 알게 되었다. However, the inventors of the present application have found that a large difference occurs in the sterilization power depending on the pH of the hypochlorous acid solution obtained by electrolyzing an aqueous sodium chloride solution through various studies and experiments.

또, 차아염소산수용액이 우수한 살균력을 갖도록 하기 위해서는 pH 5~6.5가 되도록 해야 한다는 결론을 얻었다 In addition, it was concluded that in order for the hypochlorous acid solution to have excellent sterilizing power, the pH should be 5 to 6.5.

따라서 본 발명의 살균수 제조방법은, 전해조(31)의 양극실(31b)에서 생성된 차아염소산수용액에 원수를 혼합하여 살균력이 우수한 pH를 가지는 차아염소산수용액이 되도록 하는 pH조절단계를 갖는다.Therefore, the method for producing sterilizing water according to the present invention has a pH adjusting step of mixing the raw water with the hypochlorous acid solution generated in the anode chamber 31b of the electrolytic cell 31 to make the hypochlorous acid solution having excellent pH.

우수한 살균력이 확보되는 것은 pH 5～6.5이기 때문에 pH조절단계에서는 전기분해에 의해 얻어진 차아염소산수용액이 pH 5～6.5의 차아염소산수용액이 되도록 한다. (차아염소산수용액이 가지는 유리잔류염소의 수치에 따라서도 살균력에 큰 차이가 있음을 알게 되었는데 바람직한 것은 유리잔류염소가 30ppm인 경우임을 알게 되었다. 따라서 pH조절단계에서 차아염소산수용액의 유리잔류염소도 조절하는 것이 더욱 바람직하다.)Since excellent sterilizing power is pH 5∼6.5, the hypochlorous acid aqueous solution obtained by electrolysis is adjusted to pH 5∼6.5 aqueous hypochlorite solution. (It has been found that there is a big difference in bactericidal power depending on the level of free chlorine in the hypochlorous acid solution, but it is preferable that the free residual chlorine is 30 ppm. Therefore, the free chlorine in the hypochlorous acid solution is also adjusted in the pH adjusting step. More preferably.)

차아염소산수용액의 pH를 조절하기 위해서, 전기분해에 의해 얻어진 차아염소산수용액이 배관을 따라 전기분해수단(30)의 외측으로 배출되고, 이와 같이 배출된 차아염소산수용액과 원수가 혼합되도록 하는 방법이 있다.In order to adjust the pH of the hypochlorous acid solution, there is a method in which the hypochlorous acid solution obtained by electrolysis is discharged to the outside of the electrolysis means 30 along the pipe, so that the hypochlorous acid solution and the raw water discharged in this way are mixed. .

즉, 원수의 pH는 통상 7정도이므로 전기분해에 의해 얻어진 양극실(31b)의 차아염소산수용액(pH 2～3 정도임)과 혼합하여 pH 5～6.5의 차아염소산수용액이 되도록 하는 것이다.That is, since the pH of raw water is usually about 7, it is mixed with the hypochlorous acid solution (about pH 2-3) of the anode chamber 31b obtained by electrolysis so that it may be a hypochlorous acid solution of pH 5-6.5.

공지된 통상의 전기분해 방법을 본 발명에 적용할 경우 전해조(31)의 양극실(31b)에서는 pH 2～3 정도의 차아염소산수용액이 생성되고, 음극실(31c)에서는 pH 11～12 정도의 강알칼리수가 생성된다. When a known conventional electrolysis method is applied to the present invention, a hypochlorous acid aqueous solution having a pH of 2 to 3 is produced in the anode chamber 31b of the electrolytic cell 31, and a pH of 11 to 12 in the cathode chamber 31c. Strong alkaline water is produced.

즉, 양극실에서는 강산성의 차아염소산수용액이 생성되고, 음극실(31c)에서는 강알칼리수가 생성되는 것이다.That is, a strongly acidic hypochlorous acid solution is produced in the anode chamber, and strong alkaline water is produced in the cathode chamber 31c.

그러므로 본 발명에서는 양극실(31b)의 차아염소산수용액에 원수를 섞어 살균력이 우수한 pH를 가지는 차아염소산수용액을 얻는 것이다.(전해조(31)의 음극실(31c)에서 생성되는 강알칼리수는 세정제 등으로 사용할 수 있다.)Therefore, in the present invention, the hypochlorous acid solution having excellent pH and excellent sterilizing power is obtained by mixing raw water with the hypochlorous acid solution in the anode chamber 31b. (The strong alkaline water generated in the cathode chamber 31c of the electrolytic bath 31 is used as a cleaning agent. I can use it.)

전기분해수단(30)의 외부로 배출된 차아염소산수용액이 원수와 혼합되도록 함에 있어서는 전해조(31)에서 생성된 차아염소산수용액이 배관을 따라 전기분해수단(30)의 외부로 배출되고, 그 과정에서 배관 내부로 원수가 공급됨으로써 이동되던 차아염소산수용액과 원수가 섞이도록 하는 방법을 사용할 수 있다.When the hypochlorous acid solution discharged to the outside of the electrolysis means 30 is mixed with the raw water, the hypochlorous acid solution generated in the electrolytic cell 31 is discharged to the outside of the electrolysis means 30 along the pipe, and in the process Raw water may be fed into the pipe to mix the hypochlorous acid solution with the raw water.

이때 차아염소산수용액과 원수의 혼합수단으로는 벤츄리관이나 사이클론형 또는 임펠러나 오리피스 등에 의해 혼합, 교반되는 형태로 구현할 수 있다.At this time, as the means for mixing the hypochlorous acid solution and the raw water can be implemented in a form that is mixed, stirred by a venturi tube, a cyclone type or an impeller or orifice.

이와 같이 전기분해과정을 통해 양극실(31b)에서 생성된 차아염소산수용액을 직접 원수와 혼합하는 방식을 채용하므로 낮은 pH 영역에서 생성되는 염소(Cl₂) 가스를 직접 원수와 반응시켜 pH 5～6.5 영역의 차아염소산수용액으로 환원하므로 염소가스를 공정 외부로 유출되지 않게 하여 안전하고 안정적인 pH 범위의 차아염소산수용액을 생성할 수 있다. As such, the method of directly mixing the hypochlorous acid solution generated in the anode chamber 31b with the raw water through the electrolysis process reacts the chlorine (Cl₂) gas produced in the low pH region with the raw water to pH 5∼6.5 region. Since it is reduced to the hypochlorous acid solution of the chlorine gas does not flow out of the process can produce a hypochlorous acid solution in a safe and stable pH range.

상기와 같이 원수와 혼합된 상태의 차아염소산수용액의 pH를 pH측정기(41)를 통해 측정하고, 이 측정된 데이터에 근거하여 전기분해수단(30)에 공급되는 전류량을 조절하는 방법을 통해 pH 5～6.5의 차아염소산수용액을 확보할 수 있다.As described above, the pH of the hypochlorous acid solution mixed with the raw water is measured through the pH meter 41, and the pH 5 is adjusted by adjusting the amount of current supplied to the electrolysis means 30 based on the measured data. A hypochlorous acid aqueous solution of ˜6.5 can be obtained.

또, pH측정기(41)를 통해 측정된 데이터에 근거하여 전해조(31)로 공급되는 염화나트륨수용액의 농도나 공급량을 조절하는 방법 등으로 원하는 pH 5～6.5의 차아염소산수용액을 확보할 수 있다.In addition, a hypochlorous acid aqueous solution having a desired pH of 5 to 6.5 can be secured by adjusting the concentration or supply amount of the sodium chloride aqueous solution supplied to the electrolytic cell 31 based on the data measured by the pH meter 41.
