Abstract:
하이브리드형 담수화 장치 및 이를 이용한 담수화 방법 및 재생 방법이 제공된다. 본 발명의 상기 담수화 장치는 염수의 염분 농도를 제 1 저감시키는 축전 탈 이온화 유닛; 및 상기 축전 탈 이온화 유닛에 의하여 염분이 제 1 저감된 염수의 염분을 제 2 저감시키는 역삼투 유닛을 포함하는 것을 특징으로 하며, 종래의 역삼투 방식의 담수화 장치의 고압 펌프 용량을 현저히 낮출 수 있으므로 전체적인 담수화 장치의 에너지 효율을 크게 증가시킬 수 있다. 즉, 역삼투 방식을 통해 담수화해야 하는 염수의 농도가 상기 담수화 장치 내의 축전 탈 이온화(CDI) 장치에 의해서, 일차적으로 낮아지기 때문에 담수화 장치 내의 반투막 근처에서 발생하는 삼투압이 감소하게 되며, 따라서 가해주어야 하는 고압펌프의 압력 또한 감소하게 되고 이로써 고압펌프 소비동력도 감소하여 결과적으로는 담수화 장치의 전체적인 에너지 효율이 증가한다.
Abstract:
In the organic electroluminescence (EL) device containing a bis-condensed derivative of 4-(dicyanomethylene)-2-methyl-6-(para-(dimethylaminostyryl)-4H-pyran, and the preparation thereof, the inventive organic electroluminescence device has a high luminescent efficiency and color coordinates based on a high purity, and is further simple in a synthesis and is prominent in a thermal stability, thereby providing great merits to a mass production of the organic electroluminescence device.
Abstract:
A magnetic bearing device according to an embodiment of the present invention includes a first stator which includes a first core and a first coil and supports a first rotator and a second stator which includes a second core and a second coil and supports a second rotator. The first core is located apart from the first rotator and encompasses the first rotator. The first coil, which is wound around the first core, receives a current for the first core and the first rotator to reach magnetic saturation and then receives a current in a range where the first core can maintain a magnetic flux density equal to or greater than a certain level so that the first core generates electromagnetic force with a magnetic flux density equal to or greater than a certain level. The second core is located apart from the second rotator and encompasses the second rotator. The second coil, which is wound around the second core, receives a current to make the second core generate electromagnetic force with a magnetic flux density varying at a certain ratio equal to or greater than a certain level according to the value of the applied current.
