Description

해수 전기분해를 이용한 선박 평형수 처리장치{Ship's ballast water treatment system using electrolysis of sea water}Ship's ballast water treatment system using electrolysis of sea water}

본 발명은 해수 전기분해를 이용한 선박 평형수 처리장치에 관한 것으로, 열교환방식 또는 전기히터방식의 장치와 불용성 전극을 내재한 전기분해 장치를 통하여 유입 해수의 온도가 낮은 해역에서도 전기분해 장치 내에서 안정적인 산화제(차아염소산나트륨)를 생성하여 선박 평형수 탱크 내에 해양 생태계를 교란하는 해양 생물을 효과적으로 사멸하는 장치에 관한 것이다. The present invention relates to a ballast water treatment apparatus using seawater electrolysis, which is stable in an electrolysis apparatus even in a sea area where the temperature of the incoming seawater is low through an electrolysis apparatus incorporating an insoluble electrode and a heat exchange or electric heater system. An apparatus for producing an oxidant (sodium hypochlorite) to effectively kill marine organisms disrupting marine ecosystems in ballast water tanks.

일반적으로 화물 수송이나 여객용 대형 선박은 선적 목적물을 안전하게 운송하기 위하여 선박의 하부에 위치한 별도의 탱크에 선박 평형수를 유입하여 선박의 균형을 유지한다.In general, large cargo ships or passenger ships maintain ball balance by introducing ballast water into a separate tank located at the bottom of the ship in order to safely transport the cargo.

선박의 안전한 운항을 위해 필수적인 역할을 하는 선박 평형수는 선적 목적물의 중량 변화에 따라 유입 또는 유출이 반복된다. 이는 운반 목적물을 하역하는 항만에서 선박 평형수 탱크 내부로 유입하고, 운반 목적물을 선적하는 항만에서 선박 외부로 배출한다.The ballast water, which plays an essential role for the safe operation of the ship, is repeated inflow or outflow depending on the weight change of the loading target. This flows into the ballast water tank at the port where the transport object is unloaded and discharges out of the ship at the port loading the transport object.

이 과정에서 선박 평형수 내에 포함된 다양한 종의 해양 생물이 해역으로 이동, 배출되고, 그 지역의 토착 해양 생물의 멸종, 생물 개체군의 천이(遷移) 등 해양 생태계를 교란시키는 매우 심각한 문제를 지니고 있는 것으로 보고 되고 있다.In this process, marine species of various species contained in ballast water are transported and discharged into the sea, and there are very serious problems that disturb marine ecosystems such as extinction of indigenous marine organisms in the area and transition of biological populations. It is reported.

이러한 문제점은 선박 평형수를 다른 해역권의 항만에서 배출하기 전에 선박 평형수 내에 포함된 해양 생물을 사멸처리하여 배출함으로서 근본적으로 해결할 수 있다. This problem can be fundamentally solved by killing and discharging marine life contained in the ballast water before discharging the ballast water from ports in other sea areas.

국제해사기구(IMO, International Maritime Organization)에서는 선박 평형수와 침전물의 배출에 의해 해양 오염과 생태계의 파괴현상을 방지하기 위하여 선박 평형수의 배출기준을 제정한 [선박 평형수 관리 협약]을 2004년도에 체결하였다.In 2004, the International Maritime Organization (IMO) established the Ballast Water Management Convention, which established the discharge standard for ballast water in order to prevent marine pollution and the destruction of ecosystems by the discharge of ballast water and sediment. Fastened to.

이는 선박의 크기와 기존 및 신조선 등의 적용 등을 고려하여 단계별로 관리하는 것을 골자로, 기존선에 대해서 선박 평형수를 목적지에 도착하기 전에 공해(公海) 상에서 교환해야 하며, 2009년도부터 건조되는 모든 선박에 대하여 선박 평형수 처리장치의 설치를 의무화 하였다. This is a management step by step considering the size of the ship and the application of existing and new ships, etc., the ballast water for the existing ship should be exchanged on the high seas before arriving at the destination, and since 2009 Mandatory installation of ballast water treatment systems for all ships.

선박 평형수 처리기술은 기존의 수처리 환경기술과 연계하여 개발되고 있다. 주로 오존, 염소, 기타 biocide, 여과, 자외선 조사, 고도산화 및 전기화학적 처리 등과 같은 화학적인 방법과 물리적인 방법으로 분류할 수 있으나, [선박 평형수 관리 협약]의 관리 지침의 처리 기준에 미달되거나, 처리 부산물이 인체, 선박 및 환경에 영향을 미칠 경우 IMO에 의해 국제적인 형식승인에서 배제되고 있다.The ballast water treatment technology is being developed in connection with the existing water treatment environmental technology. It can be classified mainly by chemical and physical methods such as ozone, chlorine, other biocide, filtration, UV irradiation, advanced oxidation and electrochemical treatment, but it does not meet the treatment criteria of the management guideline of [Ship Ballast Convention]. In addition, IMOs are excluded from international type approval by IMO when treatment by-products affect humans, vessels and the environment.

따라서, 선박 평형수 처리기술은 선박의 다양한 운항 경로에 따라 [선박 평 형수 관리 협약]의 관리 지침의 처리 기준을 만족하는 적절한 성능을 보장하기 위하여 탁도, 온도 및 염분 농도와 같은 해수 조건을 고려해야한다.Therefore, ballast water treatment technologies should consider seawater conditions such as turbidity, temperature and salinity concentrations to ensure adequate performance that meets the treatment criteria of the management guidelines of the [Ship Ballast Water Management Convention] according to the ship's various routes. .
