Description

세정 기능을 갖는 잔류염소 측정 장치Residual chlorine measuring device with cleaning function
본 발명은 잔류염소 측정 장치의 빛이 투과되는 부분을 세정할 수 있는 세정 기능을 갖는 잔류염소 측정 장치에 관한 것이다.The present invention relates to a residual chlorine measuring apparatus having a cleaning function capable of cleaning a portion through which light passes through the residual chlorine measuring apparatus.
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 for the ballasting operation (in the case of ballast to improve the balance, safety and maneuvering performance of the ship, etc.) and sail in the ballast state. 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 carried from remote locations is not only harmful to the new environment, but can also be 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, 해수에 최적화된 개발 제품이 아니며, 해수와 같이 잔존 이온이 과량이고 측정 방해물이 많거나 수질 상태가 좋지 않은 경우에는 측정부의 이물질로 인해 측정이 불가능하거나 신뢰도가 떨어지는 문제점이 있었다.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, it is not a development product optimized for seawater, and if there are excessive residual ions such as seawater, and there are many measurement obstacles or poor water quality, there is a problem in that measurement cannot be made due to foreign substances in the measurement unit or the reliability is low.
