상수도 소독통합관리 시스템{Waterworks disinfection management system}Waterworks disinfection management system

본 발명은 상수도 관리 시스템에 관한 것으로서, 특히 소금물을 전기분해해서 실시간으로 차아염소산나트륨을 생산하여 상수도의 관로에 주입하되 관련된 정보를 통합하여 관리할 수 있는 상수도 소독통합관리 시스템에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply management system, and more particularly, to a water supply disinfection integrated management system capable of integrating and managing related information while producing sodium hypochlorite in real time by electrolyzing brine and injecting it into a pipeline of water supply.

일반적으로, 간이상수도는 고체염소(차아염소산칼슘) 투입기, 염소가스발생기, 차아염소산나트륨 주입장치 등을 이용하여 소독처리하고 있다. 그런데, 고체염소 투입기의 경우에는 원료 특성상 미세정량을 주입하는 것이 어려울 뿐만 아니라 원료가 습기에 취약해서 취급이 어려운 문제점이 있었다. 또한, 염소가스발생기의 경우에는 가스누출로 인한 위험성이 있어 상용화가 어려웠다. 또한, 차아염소산나트륨 주입장치의 경우에는 고농도(유효염소농도 12%)의 원료를 사용하므로 장기간 보관시 농도가 크게 낮아져서 손실이 클 뿐만 아니라 농도저하로 인해 현재의 원료농도를 알 수 없기 때문에 미세정량을 주입하기 어려운 문제점이 있었다. In general, liver abnormalities are sterilized using a solid chlorine (calcium hypochlorite) injector, a chlorine gas generator, a sodium hypochlorite injector, or the like. However, in the case of a solid chlorine injector, it is difficult to inject a minute amount due to the characteristics of the raw material, and the raw material is vulnerable to moisture, which makes it difficult to handle. In addition, in the case of the chlorine gas generator there is a risk due to gas leakage it was difficult to commercialize. In addition, the sodium hypochlorite injector uses a high concentration (12% effective chlorine concentration) of raw materials, so the concentration is lowered during long-term storage, so the loss is large and the present raw material concentration is not known due to the concentration drop. There was a problem that is difficult to inject.

이에 따라, 상수도 관리 시스템을 구축하여 미세정량의 소독수를 주입할 수 있도록 제어하고, 또한 상수도 소독장치를 체계적으로 관리할 필요성이 제기되고 있는 실정이다. Accordingly, there is a need to establish a water supply management system to control the injection of micro-quantity disinfectant water and to systematically manage the water supply disinfection device.

이에 본 발명은 상기와 같은 필요성에 부응하기 위한 것으로서, 소금물을 전기분해하여 실시간으로 차아염소산나트륨을 생산하되 상수도의 관로에 미세정량을 주입할 수 있을 뿐만 아니라 체계적으로 관리할 수 있도록 된 상수도 소독통합관리 시스템을 제공하는데 그 목적이 있다.

이하, 첨부된 도면을 참조하여 본 발명을 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

도 1은 본 발명에 따른 상수도 소독통합관리 시스템을 설명하기 위한 도면이다. 1 is a view for explaining the integrated water treatment disinfection management system according to the present invention.

도면에 도시된 바와 같이, 본 발명의 상수도 소독통합관리 시스템은 상수도의 관로에 미세정량을 주입할 수 있으며 관련된 정보를 통합하여 체계적으로 관리할 수 있도록, 혼합기(110), 전기분해조(120), 정량주입펌프(130), 유량센서(140), 제어부(150), 통신부(160) 및 무선망(테트라망)으로 연결된 감시센터(200)로 이루어진다. As shown in the figure, the water supply disinfection integrated management system of the present invention can inject microquantities into the pipeline of waterworks, so that the integrated information can be systematically managed, mixer 110, electrolysis tank 120 , The metering injection pump 130, the flow sensor 140, the control unit 150, the communication unit 160 and the monitoring center 200 is connected to a wireless network (tetra network).

상기 혼합기(110)는 원수(수돗물)를 공급하는 관로에 설치되어 3% 농도의 소금물(희석염수)을 만들어낸다. 이러한 혼합기는 이미 잘 알려진 것이므로 여기에서의 구체적인 설명은 생략한다. The mixer 110 is installed in a pipeline for supplying raw water (tap water) to produce a salt water (diluted saline) of 3% concentration. Since such a mixer is well known, a detailed description thereof will be omitted.

상기 전기분해조(120)는 차아염소산나트륨 저장조 일체형의 전기분해조로서 상기 혼합기(110)로부터 소금물을 공급받아 전기분해하여 차아염소산나트륨을 생성한 후 이를 저장한다. 예컨대, 소금물을 격막(이온교환막)이 없는 일련의 전극을 통과시키는 과정에서 전극 양단에 부가된 직류전류(DC)를 이용해서 소금을 전기분해하고 이를 물과 반응시켜 소량의 수소가스와 차아염소산나트륨(NaOCl)을 생성하 여 저장할 수 있다. 한편, 상기 혼합기(110)와 전기분해조(120) 사이에는 전기분해조(120)로 유입되는 소금물의 양을 제어할 수 있도록 제어밸브(미도시)가 설치될 수 있다. The electrolysis tank 120 is a sodium hypochlorite storage tank integrated electrolysis tank receiving the brine from the mixer 110 and electrolyzed to generate sodium hypochlorite and then stores it. For example, in the process of passing salt water through a series of electrodes without a diaphragm (ion exchange membrane), the salt is electrolyzed using a direct current (DC) added at both ends of the electrode and reacted with water to react with a small amount of hydrogen gas and sodium hypochlorite. (NaOCl) can be generated and stored. Meanwhile, a control valve (not shown) may be installed between the mixer 110 and the electrolysis tank 120 to control the amount of salt water introduced into the electrolysis tank 120.

상기 정량주입펌프(130)는 상기 전기분해조(120)에 저장된 차아염소산나트륨을 펌핑하여 관로에 주입한다. The metering injection pump 130 pumps the sodium hypochlorite stored in the electrolysis tank 120 and injects it into the conduit.

상기 유량센서(140)는 관로에 설치되어 유량을 감지한다. The flow sensor 140 is installed in the pipeline to detect the flow rate.

상기 제어부(150)는 관로에 설치된 유량센서(140)로부터 유량신호를 입력받고, 유량에 비례하여 차아염소산나트륨이 관로에 주입될 수 있도록 상기 전기분해조(120) 및 정량주입펌프(130)를 제어한다. 즉, 관로의 유량에 따라 적합한 양의 차아염소산나트륨이 주입될 수 있도록 제어하는 것이다. The control unit 150 receives the flow signal from the flow sensor 140 installed in the pipeline, and the electrolysis tank 120 and the metering injection pump 130 to be injected into the pipeline in proportion to the flow rate To control. That is, to control the amount of sodium hypochlorite can be injected according to the flow rate of the pipe.

상기 통신부(160)는 상기 유량센서(140)의 유량정보, 전기분해조(120) 및 정량주입펌프(130)의 제어정보 등과 같이 상수도와 관련된 소독관리정보를 무선망 등을 이용하여 외부의 상·하수도사업소 등의 감시센터(200)로 송신한다. 이때, 상기 통신부(160)는 별도의 유지비용 없이 이용할 수 있도록 디지털 TRS(주파수공용통신) 표준인 테트라(TETRA;TErrestrial Trunked RAdio), 즉 디지털 방식의 주파수 공용통신 기술인 테트라망을 이용할 수 있는 테트라 전용모뎀을 내장하고 있는 것이 좋다. 이와 같이, 전용모뎀을 장착한 테트라망을 구축함으로써 감시센터(200)에서는 별도의 유지비용 없이도 상수도 소독관리정보를 실시간으로 수신하여 확인할 수 있으며, 또한 원격으로 관리할 수가 있다. The communication unit 160 uses the wireless network to disinfect management information related to water supply such as flow rate information of the flow rate sensor 140, control information of the electrolysis tank 120, and the metering injection pump 130. Send to the monitoring center 200, such as a sewer office. At this time, the communication unit 160 can be used without a separate maintenance fee Tetra (TEr; TErrestrial Trunked RAdio), which is a digital TRS standard (Tetra), that is, dedicated Tetra, which can use a tetra-frequency network communication technology It is good to have a modem built in. As such, by establishing a tetra network equipped with a dedicated modem, the monitoring center 200 can receive and confirm water disinfection management information in real time without additional maintenance costs, and can also remotely manage it.

본 발명에 따른 상수도 소독통합관리 시스템의 작용을 설명하기로 한다. The operation of the integrated water treatment disinfection management system according to the present invention will be described.

먼저, 관로에 설치된 유량센서(140)로부터 입력되는 유량신호에 따라 제어부(150)에서는 전기분해조(120)의 전극으로 인가되는 전류를 제어하여 차아염소산나트륨 생성량을 조절하게 된다. 즉, 관로의 유량이 많을수록 더 많은 양의 차아염소산나트륨을 생성할 수 있도록 제어하는 것이다. First, the controller 150 controls the amount of sodium hypochlorite produced by controlling the current applied to the electrode of the electrolytic bath 120 according to the flow signal input from the flow sensor 140 installed in the pipeline. In other words, the greater the flow rate in the pipeline, the greater the amount of sodium hypochlorite produced.

그리고, 상기 유량센서(140)에 의한 유량신호에 의해 상기 제어부(150)는 상기 정량주입펌프(130)를 제어하여 관로의 유량에 적합하도록 차아염소산나트륨의 펌핑량을 조절하게 된다. 즉, 관로의 유량이 많을수록 더 많은 양의 차아염소산나트륨이 주입될 수 있도록 제어하는 것이다. In addition, the control unit 150 controls the metering injection pump 130 to adjust the pumping amount of sodium hypochlorite to suit the flow rate of the pipeline by the flow rate signal by the flow sensor 140. In other words, the more the flow rate of the pipe is controlled so that a larger amount of sodium hypochlorite can be injected.

또한, 상기 유량센서(140)에 의한 유량정보, 전기분해조(120) 및 정량주입펌프(130)의 제어정보 등의 상수도 소독관리정보는 통신부(160)를 통해 외부의 상·하수도사업소 등의 감시센터(200)로 실시간 전달되어 관리된다. In addition, water disinfection management information, such as flow rate information by the flow sensor 140, control information of the electrolysis tank 120 and the metering injection pump 130, such as external water and sewage offices through the communication unit 160 Real-time delivery to the monitoring center 200 is managed.
