밸러스트수(ballast water)란 선박이 짐을 싣지 않고 운항하는 경우에 선박의 균형을 유지하기 위해 선박 내의 밸러스트 탱크에 채우는 해수를 의미한다. 국제교역량의 증가와 함께 해상운송 비율이 점점 증가하고 있고 그에 따라 선박 수의 증가 및 대형화가 빠르게 이루어지고 있어 선박에서 사용하는 밸러스트수의 양도 크게 증가하고 있다. 선박에서 사용하는 밸러스트수의 양이 증가함에 따라 외래 해양생물종들로 인한 토착 해양생태계의 피해 발생 사례 역시 증가하고 있는바, 이러한 국제적인 환경문제를 해결하기 위해 2004년도에 국제해사기구(IMO)에서 '선박의 밸러스트수와 침전물의 통제와 관리에 대한 국제협약'이 완성되어 2009년부터 신규 건조되는 선박에 밸러스트수 처리장치가 의무적으로 설치되고 있다.Ballast water refers to seawater that fills ballast tanks in ships in order to balance the ships when the ships operate without loading. As the international trade volume increases, the rate of maritime transportation is gradually increasing. Accordingly, the number of ships and the size of ships are increasing rapidly, and the amount of ballast used by ships is also greatly increased. As the amount of ballast water used by ships increases, the incidence of damage to indigenous marine ecosystems caused by foreign marine species also increases.In 2004, the International Maritime Organization (IMO) Since 2009, the International Convention on the Control and Management of Ballast Water and Sediment of Ships has been completed, and a ballast water treatment system is mandatory to be installed on newly constructed vessels from 2009.
종래 밸러스트수를 처리하기 위한 방식으로는 밸러스트수를 해상에서 교환하거나 육상에서 처리하는 방식이 있었으나, 비효율적인 단점이 있어 선박 내에 밸러스트수를 처리하기 위한 처리시설을 설치하는 방식이 많이 활용되고 있고, 특히 밸러스트수 처리시설에 사용되는 처리방식으로 필터를 사용한 여과방식이 주로 이용되고 있는데, 선박이 대형화됨에 따라 큰 선박에서는 많은 양의 밸러스트수를 처리하여야 할 필요성이 증대되므로, 그에 따라 대용량의 밸러스트수를 처리할 수 있는 멀티케이지 타입 밸러스트수 여과장치가 사용되고 있다.Conventionally, a method for treating ballast water has been a method of exchanging ballast water at sea or treating it on land. However, there is an inefficient disadvantage, and a method of installing a ballast water treatment facility in a ship has been widely used. In particular, the filtration method using a filter is mainly used as a treatment method used in a ballast water treatment facility. As the size of a large vessel increases, the necessity of treating a large amount of ballast water increases in large vessels, and accordingly, a large amount of ballast water A multi-cage type ballast water filtration device that can handle the is used.
도 1은 종래 멀티케이지 타입 밸러스트수 여과장치의 부분절단 분해사시도이며, 도 2는 종래 멀티케이지 타입 밸러스트수 여과장치의 평면도이고, 도 3은 종래 멀티케이지 타입 밸러스트수 여과장치의 저면도인데, 이하에서는 도 1 내지 3을 참조하여 종래 멀티케이지 타입 밸러스트수 여과장치를 살펴보도록 한다.1 is a partially cutaway exploded perspective view of a conventional multi-cage type ballast water filtration device, FIG. 2 is a plan view of a conventional multi-cage type ballast water filtration device, and FIG. 3 is a bottom view of a conventional multi-cage type ballast water filtration device. In Figure 1 to 3 to look at the conventional multi-cage type ballast water filtration device.
종래 멀티케이지 타입 밸러스트수 여과장치는 상기 배출관(76)이 각각 상기 바디(72)에서 돌출되어 하나의 연결관(77)에 연통되므로, 상기 여과장치의 외부의 구성이 복잡하고 크기가 커져서 장치의 설치 및 보수가 어렵고, 특히 선박이라는 특수한 환경에서는 이러한 여과장치가 설치되는 공간 역시 매우 협소(선박 고유의 목적을 위한 공간을 넓게 확보하기 위해 기계실과 같은 공간은 상대적으로 협소하게 설계됨)하기 때문에 여과장치의 외부공간이 매우 협소하다는 점을 감안한다면, 종래와 같이 여과장치의 외부에 구성들이 집중되는 구조에서는 더욱 장치의 설치 및 보수의 어려움이 증대될 수밖에 없는 문제를 안고 있다. 또한, 상대적으로 작은 내부 면적을 차지하는 배출관(76)이 긴 길이를 가지고 절곡되므로 쉽게 이물질이 상기 배출관(76) 내부에 끼게 되어 이물질과 역세척수의 배출을 방해하는 큰 배압이 형성되는 문제가 있다.In the conventional multi-cage type ballast water filtration device, since the discharge pipes 76 protrude from the body 72 and communicate with one connection pipe 77, the external configuration of the filtration device is complicated and the size is increased. It is difficult to install and repair, especially in the special environment such as ship, because the space where the filtration device is installed is also very narrow (the space such as the machine room is designed relatively narrow to secure the space for the ship's own purpose). Given that the outer space of the very narrow, as in the conventional structure is concentrated on the outside of the filtration device has a problem that the difficulty of installation and repair of the device will further increase. In addition, since the discharge pipe 76, which occupies a relatively small inner area, is bent with a long length, foreign matter is easily trapped inside the discharge pipe 76, thereby causing a large back pressure to prevent discharge of foreign matter and backwash water.
또한, 종래 멀티케이지 타입 밸러스트수 여과장치는 이물질과 역세척수가 배출되는 배출관(76)이 상기 바디(72) 내부에 용접되어 형성되므로, 상기 바디(72)의 내부와 배출관(76)의 부식을 방지하는 도료를 상기 배출관(76)을 상기 바디(72)에 설치한 후에 작업자가 상기 바디(72)의 내부에 들어가 도포할 수밖에 없어, 상기 바디 내부의 부식을 방지하기 위한 도장 작업이 어렵게 되어 장치의 설치 및 유지가 어려운 문제가 있다.In addition, the conventional multi-cage type ballast water filtration device is formed by welding the discharge pipe 76 for discharging foreign matter and backwash water in the body 72, the corrosion of the interior of the body 72 and the discharge pipe 76. After installing the discharge pipe 76 to the body 72 to prevent the paint to enter the inside of the body 72, the operator has no choice but to apply the coating work to prevent corrosion of the inside of the body is difficult There is a problem that is difficult to install and maintain.
또한, 종래 멀티케이지 타입 밸러스트수 여과장치는 필터(71)의 외부, 바디(72) 내부의 압력을 측정하는 제1압력센서(73)와, 각 여과유닛(필터(71)와 자동세척부(74)로 이루어진 유닛을 의미)마다 설치되어 각 여과유닛의 필터(71) 내부의 압력을 측정하는 제2압력센서(75)를 포함하여, 필터(71)에 이물질이 부착된 경우 상기 필터(71) 내부의 압력이 증가할 것이라는 이론적 배경을 기초로 상기 바디(72) 내부의 압력과 일정 범위 이상의 차압이 발생하는 여과유닛별로 순차적으로 상기 자동세척부(74)를 구동시켜, 상기 필터(71)를 역세척하였다. 하지만, 특정 여과유닛의 필터(71)를 세척하여 이물질을 제거하였음에도 상기 특정 여과유닛의 필터(71) 내부의 압력이 다시 급속하게 증가하여 타 필터(71)가 역세척되지 않고 상기 특정 유과유닛의 필터(71)가 계속적으로 역세척되는 문제가 있다.In addition, the conventional multi-cage type ballast water filtration device has a first pressure sensor 73 for measuring the pressure of the outside of the filter 71, the body 72, and each filtration unit (filter 71 and the automatic cleaning unit ( And a second pressure sensor 75 installed at each filter unit to measure the pressure inside the filter 71 of each filtration unit, and the foreign matter is attached to the filter 71. On the basis of the theoretical background that the pressure inside the body will increase, the automatic cleaning unit 74 is sequentially driven for each filtration unit in which the pressure inside the body 72 and a differential pressure of a predetermined range or more are generated, and thus the filter 71. Backwashed. However, even when the foreign matter is removed by washing the filter 71 of the specific filtration unit, the pressure inside the filter 71 of the specific filtration unit is rapidly increased again so that the other filter 71 is not backwashed, There is a problem that the filter 71 is continuously backwashed.

It is not excluded that the case is installed at the inlet of the outlet 120 of the) and the pressure inside the body 10, more specifically, the interior of the filtration chamber (S2), the filtered ballast water is measured and measured. By transmitting the value to the controller (not shown), the controller (not shown) allows the pressure inside the body 10 to be always managed.
상기 제2압력측정단계(S2)에서는 도 6에 도시된 바와 같이, 필터(20) 내부의 압력을 측정할 수 있도록 배치된 복수 개(여과유닛의 개수보다 적음)의 제2압력센서(60)를 이용하여 상기 제2압력센서(60)가 설치된 각 여과유닛별로 그 필터(20) 내부의 압력을 측정하여 그 측정값을 제어부(미도시)에 전송함으로써, 제어부(미도시)에서 필터(20) 내부의 압력을 수시로 체크할 수 있도록 한다.In the second pressure measuring step S2, as illustrated in FIG. 6, a plurality of second pressure sensors 60 (less than the number of filtration units) disposed to measure the pressure inside the filter 20.
