Description

잔류염소 측정 장치용 시약 공급 장치Reagent supply device for residual chlorine measuring device
본 발명은 잔류염소 측정 장치에 시약을 공급하는 장치에 관한 것이다.The present invention relates to a device for supplying a reagent to a residual chlorine measuring device.
일반적으로 해상에서 운송하는 화물 선박은 유사한 화물의 상호 교환을 위하여 왕복 항해하는 선박을 제외하고는 대부분 편도 운항을 한다. 그리고, 편도 운항을 만재 상태로 항해한 후 귀환 항해 시에는 선박의 균형, 안전성 및 조종 성능 향상 등을 위하여 밸러스트 수(평형수; ballast water)를 선내로 유입하여 밸러스트 상태로 항해를 하게 된다.Generally, cargo ships transported by sea are mostly one-way except for ships reciprocating to exchange similar cargoes. In addition, after returning to the full sail after the one-way operation, the ballast water (ballast water) is introduced into the ship and sailed in the ballast state for improving the balance, safety, and steering performance of the ship.
이때, 밸러스트 수는 밸러스팅 작업(ballast시에는 선박의 균형, 안전성 및 조종 성능 향상 등을 위하여 밸러스트 수(평형수; ballast water)를 선내로 유입하여 밸러스트 상태로 항해를 하게 된다.ing operation)을 통해 한 항구에서 채워져서 다른 곳으로 이송되고, 디밸러스팅 작업(deballasting operation)을 통해 새로운 항구 내에 배출된다. 이와 같이, 먼 위치로부터 실려져 온 밸러스트 수에 포함된 해양 생물 및 병원균의 방출은 새로운 환경에 유해할 뿐만 아니라, 새로운 항구에서도 사람과 동물 모두에게 위험할 수 있다.At this time, the ballast water is ballast water (ballast water) is introduced into the ship to navigate the ballast state in order to improve the balance, safety and maneuvering performance of the ballast during ballasting (ing operation). It is filled in one port and transported to another, and discharged in a new port through a deballasting operation. As such, the release of marine organisms and pathogens contained in ballast water taken from remote locations is not only harmful to the new environment, but also dangerous to both humans and animals in new ports.
비-천연적인 해양 생물을 신규 생태계로 도입시키면, 신규 종에 대해 자연적인 방어체계를 지니고 있지 않을 수 있는 천연 식물군 및 동물군에게 파괴적인 효과를 미칠 수 있다. 또한, 콜레라와 같은 해로운 세균성 병원균이 원래의 항구에 존재할 수 있다. 이러한 병원균은 시간이 지남에 따라 밸러스트 탱크 내에서 증식되어, 이들이 방출되는 영역에서 질병을 발생시킬 수 있다.Introducing non-natural marine life into new ecosystems can have destructive effects on natural flora and fauna that may not have natural defenses against new species. In addition, harmful bacterial pathogens such as cholera may be present in the original ports. These pathogens can multiply in the ballast tanks over time, causing disease in the areas where they are released.
이러한 해양 생물 및 병원균에 의해 제기되는 위험을 제거하기 위해, 밸러스팅 작업 또는 디밸러스팅 작업 중에 밸러스트 수를 전기분해하거나 약품을 주입하여 살균 처리하는 작업을 하게 된다. 2004년 국제해사기구(IMO)에서는 선박평형수 및 침전물의 배출 규제와 관리에 관한 협약"을 채택함에 따라 국제 항해 선박은 밸러스트수 처리 장치를 설치해야 항해를 할 수 있게 되었다. 이 때문에, 밸러스트수 처리 장치의 한 구성품인 잔류염소 측정 장치에 대한 시장의 수요가 증가할 것으로 예상된다. In order to eliminate the risk posed by these marine organisms and pathogens, the ballast water is electrolyzed or injected with chemicals to sterilize during ballasting or deballasting. In 2004, the International Maritime Organization (IMO) adopted the Convention on the Regulation and Management of Ballast Water and Sediment Emissions, "allowing international sailing vessels to install a ballast water treatment system for navigation. It is expected that the market demand for residual chlorine measuring devices, one component of the processing equipment, will increase.
현재 잔류염소 측정 장치는 국내외 여러 기업들에서 제조 및 판매 중에 있으며, 상수도 및 환경 분석 등 타 분야에서도 오래전부터 사용되고 있다. 그러나, 해수 내 잔류염소 측정장치의 경우 시약 공급부가 별도의 펌프, 체크 밸브, 덕빌 체크 밸브(duckbill check valve) 등을 포함하여 구성되기 때문에, 제작의 복잡성 및 원가 상승, 부품 고장으로 인한 유지 비용이 증가한다는 문제가 있다. 특히, 체크 밸브는 온/오프를 제어하는 스프링을 포함하는데, 시약의 고착 및 부식이 발생하는 경우, 스프링의 정밀한 작동을 방해하여 시약의 누설이 발생할 수 있고, 이는 제품의 내구성 및 신뢰도를 저하시키는 원인이 되었다.Currently, residual chlorine measuring devices are being manufactured and sold by various companies at home and abroad, and have been used for a long time in other fields such as water supply and environmental analysis. However, in the case of the residual chlorine measuring device in the seawater, since the reagent supply unit includes a separate pump, a check valve, a duckbill check valve, and the like, the maintenance cost due to manufacturing complexity, cost increase, and component failure is increased. There is a problem that increases. In particular, the check valve includes a spring for controlling the on / off, which, in the event of sticking and corrosion of the reagent, may interfere with the precise operation of the spring, resulting in leakage of the reagent, which reduces the durability and reliability of the product. Caused it.
또한, 종래의 잔류염소 측정 장치의 시약 주입부는 펌프에 의해 시약을 공급하기 때문에, 시약 저장 탱크에 시약이 소량만 남는 경우, 펌프에 의한 시약의 토출량이 불안정해지고, 공기가 혼합되어 측정 장치의 신뢰도를 저하시키는 문제가 있었다.In addition, since the reagent injecting unit of the conventional residual chlorine measuring device supplies the reagent by a pump, when only a small amount of reagent remains in the reagent storage tank, the discharge amount of the reagent by the pump becomes unstable, and the air is mixed, so that the reliability of the measuring device There was a problem degrading.

도 1과 2를 참조하면, 본 발명에 따른 잔류염소 측정 장치용 시약 공급 장치는 잔류염소 측정 장치(100) 측으로 유입되는 시료(잔류염소를 함유한 유체, 예를 들면 밸러스트수)에 시약(발색 시약 및 버퍼 용액)을 주입하는 장치로서, 시료 배관(200), 시약 공급 포트(300) 시약 저장 탱크(400) 및 솔레노이드 밸브(500)를 포함한다.1 and 2, the reagent supply apparatus for the residual chlorine measuring apparatus according to the present invention is a reagent (color development) to the sample (fluid containing residual chlorine, for example, ballast water) flowing into the residual chlorine measuring apparatus 100 side; Reagent and buffer solution), including a sample pipe 200, reagent supply port 300, reagent storage tank 400 and the solenoid valve (500).
시료 배관(200)은 일측이 잔류염소 측정 장치(100)에 연결되고, 타측이 시료 메인 배관(예를 들면, 밸러스트 배관)에 연결되어, 측정 대상 시료를 잔류 염소 측정 장치(100)로 유입시킨다.One side of the sample pipe 200 is connected to the residual chlorine measuring device 100, and the other side thereof is connected to the sample main pipe (for example, ballast pipe) to introduce the sample to be measured into the residual chlorine measuring device 100. .
시약 공급 포트(300)는 시료 배관(200)의 일측에 형성되어 후술되는 시약 저장 탱크(400)의 시약이 시료 배관(200)으로 유입되도록 한다. 여기서, 시약 공급 포트(300)는 내주연에 체결 나사산을 구비하여, 후술되는 솔레노이드 밸브(500)와 나사 체결될 수 있다.The reagent supply port 300 is formed on one side of the sample pipe 200 to allow the reagent of the reagent storage tank 400 to be described later to flow into the sample pipe 200. Here, the reagent supply port 300 is provided with a fastening screw thread on the inner circumference, and may be screwed with the solenoid valve 500 to be described later.
시약 저장 탱크(400)는 소정량의 시약을 저장하고, 시약 공급 포트(300)에 거꾸로, 즉 출구가 시약 공급 포트(300) 측을 향하도록 설치된다. 이에 따라, 시약 저장 탱크(400) 내부의 시약은 중력에 의해 시약 공급 포트(300)를 거쳐 시료 배관(200) 안으로 공급될 수 있다.The reagent storage tank 400 stores a predetermined amount of reagent and is installed upside down to the reagent supply port 300, that is, the outlet is directed toward the reagent supply port 300 side. Accordingly, the reagent in the reagent storage tank 400 may be supplied into the sample pipe 200 through the reagent supply port 300 by gravity.
솔레노이드 밸브(500)는 시약 공급 포트(300)와 시약 저장 탱크(400) 사이에 설치되어, 시약 저장 탱크(400)의 시약 공급을 단속하는 역할을 한다. 여기서, 솔레노이드 밸브(500)는 시약 저장 탱크(400)의 시약이 설정된 양만큼씩 시료 배관(200)에 정량 공급되도록 작동이 제어된다. 한편, 솔레노이드 밸브(500)는 출구 측이 시약 공급 포트(300)에 나사 체결된다. 그리고, 입구 측에는 튜브(600)가 연결되고, 이 튜브(600)는 시약 저장 탱크(400)의 출구 측에 결합된다. 따라서, 시약 저장 탱크(400)의 시약은 중력에 의해 시약 저장 탱크(400)의 출구로부터 튜브(600), 솔레노이드 밸브(500) 및 시약 공급 포트(300)를 거쳐 시료 배관(200)으로 공급된다.The solenoid valve 500 is installed between the reagent supply port 300 and the reagent storage tank 400 to serve to interrupt the reagent supply of the reagent storage tank 400. Here, the solenoid valve 500 is controlled to operate so that the reagent of the reagent storage tank 400 is quantitatively supplied to the sample pipe 200 by a set amount. On the other hand, the solenoid valve 500, the outlet side is screwed to the reagent supply port (300). In addition, a tube 600 is connected to the inlet side, and the tube 600 is coupled to the outlet side of the reagent storage tank 400. Accordingly, the reagent of the reagent storage tank 400 is supplied to the sample pipe 200 by gravity from the outlet of the reagent storage tank 400 via the tube 600, the solenoid valve 500, and the reagent supply port 300. .
이와 같은 구성에 의해, 본 발명에 따른 잔류염소 측정 장치용 시약 공급 장치는 시약 저장 탱크(400)의 시약이 중력에 의해 시료 배관(200)으로 공급되기 때문에 별도의 공급 펌프를 필요로 하지 않는다. 따라서, 시약 저장 탱크(400)에 소량의 시약이 남은 경우에도 시약 공급이 안정적으로 이루어질 수 있어, 잔류염소 측정 장치(100)의 신뢰도를 유지할 수 있다.With such a configuration, the reagent supply device for the residual chlorine measuring device according to the present invention does not require a separate feed pump because the reagents of the reagent storage tank 400 are supplied to the sample pipe 200 by gravity. Therefore, even when a small amount of reagent is left in the reagent storage tank 400, the reagent supply can be made stable, and thus the reliability of the residual chlorine measuring apparatus 100 can be maintained.
