Description
본 발명은 부식에 강한 취수 구조에 관한 것으로, 보다 상세하게는 취수 수직관과 바 스크린이 및 덮개의 재질을 부식에 강한 GRP(Glassfibre Reinforced Plastic Pipe)로 제작함으로써, 유지 및 관리가 쉽고, 아울러 무게가 콘크리트 및 카본 스틸보다 가벼워 설치상에 어려움을 해소할 수 있으며, 나아가 대용량 취수시스템에 적용시킬 수 있도록 한 것이다.The present invention relates to a corrosion resistant water intake structure, and more particularly, by making the material of the water intake vertical pipe and the bar screen and the cover into a corrosion resistant glass reinforced plastic pipe (GRP), which is easy to maintain and manage, Because it is lighter than concrete and carbon steel, it can solve the difficulty of installation and can be applied to large capacity water intake system.
통상적으로 해수담수화 증발기 및 부대 설비에 대하여 필요한 해수를 취수하는 방법에는 여러가지 형태의 해수 취수 시스템(Seawater Intake System)이 적용되고 있다.In general, various types of seawater intake systems have been applied to the method of collecting seawater required for the seawater desalination evaporator and the auxiliary equipment.
특히 해수 온도가 낮고 불순물이 적은 양질의 해수를 취수하기 위해서는 해안으로부터 소정거리 만큼 떨어진 해저(약 10m)에서 필요한 해수를 취수하는 방식(Offshore Deep Intake System)이 현재 기술적인 측면에서 가장 선호되고 있다.In particular, in order to take in high-quality seawater with low seawater temperature and low impurities, offshore deep intake system is currently preferred in terms of technology.
또한, 취수 수직관(Intake Riser)의 구조는 기본적으로 해수를 취수하는 과정에 해수에 포함된 입자가 큰 불순물이 유입되는 것을 방지하고자 바 스크린(Bar Screens)이 설치된다.In addition, the structure of the intake riser (Intake Riser) is basically installed bar screens (Bar Screens) in order to prevent the large impurities in the particles contained in the seawater in the process of taking in the seawater.
앞서기술된 취수 수직관(Intake Riser)은 부식성이 강한 해수에 견딜 수 있도록 하기 위하여 콘크리트(Concrete)로 만들어진 프레임(Frame)과 톱 플레이트(Top Plate)의 8각형 기중 형태의 형상을 가지며 각 부분(Section)에는 불순물의 제거를 위해 스틸(Steel)재질로 이루어진 바 스크린(Bar Screens)이 설치되거나 또는 전체가 스틸로 제작되는 일체형의 원통 구조로 제작된다.The intake riser described above has the shape of an octagonal lift of a frame and a top plate made of concrete in order to withstand corrosive seawater. In the section, bar screens made of steel materials are installed to remove impurities, or the entire cylindrical structure is made of steel.
그런데, 상기 바 스크린(Bar Screens)을 위한 프레임(Frame)과 톱 플레이트(Top Plate)가 콘크리트(Concrete)로 제작되기 때문에 용량이 큰 취수 수직관(Intake Riser)을 이와 같은 방식으로 설계할 경우, 취수 수직관(IntakeRiser)의 중량이 수십톤이 되어 해저에 설치시, 특별한 중장비가 필요하고, 그에 따라 설치상에 애로사항이 발생되었다.However, when the frame and the top plate for the bar screens are made of concrete, the intake riser having a large capacity is designed in this manner. When the intake riser weighed several tens of tons, installation on the sea floor required special heavy equipment, which caused difficulties in installation.
또한, 불순물 유입을 방지하기 위하여 설치되는 바 스크린(Bar Screens)은 경제적인 이유 때문에 통상 카본 스틸(Carbon Steel)로 제작되는데, 이 경우 부식성이 강한 해수로부터 부식을 방지하기 위하여 별도의 방식설비(예를들어 희생양극 : 알루미늄 덩어리)를 부착시켰으나, 이 희생양극의 부식 수명이 끝나면 부식이 급속히 진행됨으로써, 주기적으로 수중관찰이 요구되어 관리 및 유지보수에 상당한 어려움이 있었다.In addition, bar screens installed to prevent the inflow of impurities are usually made of carbon steel for economic reasons. In this case, a separate anticorrosive facility (eg, to prevent corrosion from highly corrosive seawater) is used. For example, a sacrificial anode (aluminum lump) was attached, but the corrosion progressed rapidly at the end of the corrosion life of the sacrificial anode, which required periodic underwater observations, which resulted in considerable difficulties in management and maintenance.
이에 본 발명은 상기와 같은 문제점을 해소하기 위해 제안된 것으로, 취수 수직관과 바 스크린이 및 덮개의 재질을 부식에 강한 재질로 제작함으로써, 유지 및 관리가 쉽고, 아울러 무게가 콘크리트 및 카본 스틸보다 가벼워 설치상에 어려움을 해소할 수 있으며, 나아가 대용량 취수시스템에 적용시킬 수 있도록 하는 점에 목적이 있다.Therefore, the present invention has been proposed to solve the above problems, the intake vertical pipe and bar screen and the material of the cover is made of a material resistant to corrosion, it is easy to maintain and manage, and the weight is better than concrete and carbon steel It is light and can solve the difficulties in installation, and furthermore, the purpose is to be able to apply to large capacity intake system.
