본 발명은 간이 상수시설, 수영장 또는 목욕탕용 살균 목적의 전기화학적 살균제 발생 장치에 관한 것으로, 더욱 상세하게는 일정량의 차아염소산소다를 발생시켜 주입함으로써 적정농도의 잔류염소량을 자동으로 항상 유지할 수 있는 전기화학적 살균제 발생 시스템에 관한 것이다.The present invention relates to an electrochemical disinfectant generating device for sterilization purposes for simple water supply facilities, swimming pools or baths, and more particularly, by generating and injecting a certain amount of sodium hypochlorite, an electric power capable of automatically maintaining an appropriate concentration of residual chlorine at all times. A chemical fungicide generating system.

종래의 소독방법은 일반 정수장 및 소규모 정수시설, 수영장 및 목욕탕등에서는 소독용 약품으로 고농도의 액체 염소를(NaOCl) 사용하고 있으며 안전설비 보완으로 사고 위험성은 줄어들고 있으나 아직 안전관리에 많은 문제점을 가지고 있다. 따라서, 화학약품을 사용하지 않는 전기화학적인 차아염소산소다 발생장치가 그 대안이 될 수 있다. 그런데, 전기화학장치는 직류전원에의해 운전이 되고, 에너지 및 환경보호 측면에서 전기화학적 살균제발생 시스템의 구동전원으로 재생에너지(태양전지 또는 풍력에너지)의 도입이 필요하다.Conventional disinfection methods use high-concentration liquid chlorine (NaOCl) as a disinfectant in general water purification plants, small water purification facilities, swimming pools and baths, and the risk of accidents is reduced by supplementing safety facilities, but there are still many problems in safety management. . Thus, an electrochemical sodium hypochlorite generator that does not use chemicals may be an alternative. By the way, the electrochemical device is driven by a DC power supply, and in terms of energy and environmental protection, it is necessary to introduce renewable energy (solar cell or wind energy) as a driving power source of the electrochemical sterilizer generation system.

본 발명은 상기 종래 기술의 문제점을 해소하기 위해 안출된 것으로, 전기화학적 차아염소산 소다 발생기의 전원으로 재생에너지(태양전지 또는 풍력에너지에의한 전력 공급)시스템을 도입함으로써 인체에 무해하며, 최소의 유지비로무인작동되는 간이상수시설 또는 수영장 또는 목욕탕등의 살균 목적용 전기화학적 차아염소산소다 발생기를 제공하는 데 그 목적이 있다.The present invention has been made to solve the problems of the prior art, by introducing a renewable energy (power supply by solar cells or wind energy) as a power source of electrochemical hypochlorite soda generator, harmless to the human body An object of the present invention is to provide an electrochemical sodium hypochlorite generator for sterilization purposes, such as an unattended operation facility or swimming pool or bathhouse, which is operated unattended for maintenance costs.

상술한 목적을 달성하기 위해 본 발명은, 액상의 차아염소산나트륨(NaOCl)를 발생시키는 전기화학적 반응부; 발생된 차아염소산나트륨(NaOCl)를 저장하는 저장부, 차아염소산 소다를 공급하기 위한 저장조 하부에 설치된 펌프와; 상기 전기화학 반응부에 전원을 공급하기 위한 솔라셀 또는 풍력에너지 및 야간 또는 흐린날을 대비한 보조 직류 전원부로 구성된 전원 공급부를 포함하는 시스템을 특징으로 한다.The present invention to achieve the above object, the electrochemical reaction unit for generating a liquid sodium hypochlorite (NaOCl); A storage unit for storing the generated sodium hypochlorite (NaOCl), and a pump installed at a lower portion of the reservoir for supplying sodium hypochlorite; It characterized by a system comprising a power supply consisting of a solar cell or wind energy for supplying power to the electrochemical reaction unit and an auxiliary DC power supply for night or cloudy days.

이하 본 발명의 바람직한 실시예를 첨부된 도면으로 상세하게 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.

첨부된 도면 1은 본 발명에 따른 전기화학 반응부에 공급하는 전류의 계통도이고 도면 2는 간이 상수시설용 차아염소산소다 발생 및 투입장치의 구성을 나타내는 개략도이다.1 is a schematic diagram of a current supplied to an electrochemical reaction unit according to the present invention, and FIG. 2 is a schematic diagram showing the configuration of a sodium hypochlorite generation and input device for a simple water purification facility.

도1에서와 같이 전류는 태양광(8) 또는 풍력(9)에의해 발생되는 전원은 직류로 전기화학반응부(1)를 직접 구동 할 수 있다. 그러나, 태양에너지의 조사량이나 풍력에너지의 풍력의 세기는 일정치 않아 이를 보상하여야 하며, 이에 이를 위한 제어시스템을 구성하여야 한다. 일 처리 3000톤의 경우 전기화학반응기(1)을 운전하기 위해서는 약 12V*200A의 직류전원이 필요하다. 이를 위해 이 용량에 적합한 태양전지(8)또는 풍력에너지(9)를 설치한다. 이들 시스템은 주변 환경에의해 변화하므로 태양에너지 또는 풍력에너지에서 발생하는 전기 에너지 즉 전류(10)와 전압(11)을 측정하여 콘트롤러(6)에서 주어진 셋팅치와 비교를 하며 만약 전력이 부족하면 부족분을 보조전원(7)에서 추가로 공급해야 할 양을 지시한다(12). 이에 따라, 보조전원(7)에서 공급한 전류와 재생전원에서 공급하는 전류가 합해져(4) 전기분해반응부에 공급된다.As shown in FIG. 1, the electric current generated by the solar light 8 or the wind 9 may directly drive the electrochemical reaction part 1 by direct current. However, the irradiation amount of solar energy or the strength of wind power of wind energy is not constant, and this must be compensated for, and a control system for this should be configured. In the case of 3000 tons of work, DC power of about 12V * 200A is required to operate the electrochemical reactor (1). To this end, solar cells 8 or wind energy 9 suitable for this capacity are installed. Since these systems are changed by the environment, the electric energy generated from solar or wind energy, that is, current (10) and voltage (11), is measured and compared with the settings given by the controller (6). Indicates an amount to be additionally supplied from the auxiliary power source 7 (12). Accordingly, the current supplied from the auxiliary power source 7 and the current supplied from the regenerative power source are combined (4) and supplied to the electrolysis reaction unit.

도2는 도1에의해 재생전원에의해 공급된 전기에 의해 운전 가능한 일반적인 전기화학적인 차아염소산 소다 발생기이다. 이들의 작동원리를 살펴보면 다음과 같다.FIG. 2 is a typical electrochemical hypochlorite soda generator operable by electricity supplied by the regenerative power supply by FIG. The principle of operation is as follows.

In the brine saturation tank (4), the salt is saturated, and the brine saturated to about 20wt% is transferred to the bellows pump (6). At this time, the salt water is mixed with the water branched after the water softener (5), and the concentration of the mixed brine is controlled. It is adjusted to about 1 to 4 wt% by the valve 100 operated by the valve, and then supplied to the electrochemical reaction unit (electrolyzer 3). In the electrochemical reaction unit 3, a saltwater electrolysis reaction occurs by a direct current supplied from a regenerative power system and a direct current supply rectifier (1 in FIG. 1), which generates a bactericide mainly containing sodium hypochlorite. The principle of the electrochemically generated reaction of sodium hypochlorite is as follows.

The ionized chlorine ion is oxidized at the anode to produce chlorine, which is the main component of the disinfectant. In addition, the ionized sodium ions move to the cathode under an electric field, and react with unreacted hydroxide ions near the cathode to produce caustic soda of Scheme 5. In addition, hydrogen ions transferred to the cathode generate hydrogen by the reaction scheme 4.
