Abstract:
PURPOSE: A seawater desalting device having hydrophilic and hydrophobic moisture separation part is provided to form moisture separation part which can be changed into hydrophilic and hydrophobic property and to collect moisture from the vapor and to obtain moisture from the vaporized seawater easily. CONSTITUTION: The seawater desalting device having hydrophilic and hydrophobic moisture separation part includes: a fresh water segregation(20); a moisture separation part; an transform unit; and a fresh water transfer pipe(51). The fresh water segregation flows in the vapor vaporized from the reaction chamber(10) through the vapor conveying pipe(11). The moisture separation part is arranged inside the fresh water segregation. The moisture separation part has the moisture separation section. The moisture separation section separates moisture from the vapor transferred from the reaction chamber. The transform unit is installed in one side of the fresh water segregation. The transform unit changes the surface property of the moisture separation section of the moisture separation part into the hydrophilic or hydrophobic. The fresh water transfer pipe is installed in the lower part of the fresh water segregation. The fresh water transfer pipe transfers the separated moisture to the fresh water reservoir(50).

본 발명은 탁도 측정용 프로브에 관한 것으로서, 더욱 상세하게는 시료수의 탁도를 측정하기 위한 프로브에 마련된 발광창 및 수광창에 고분자막을 형성하여 미생물 또는 부유물질의 침착을 방지함으로써 시료수의 탁도를 정밀하게 측정할 수 있는 프로브에 관한 것이다. 본 발명은 광이 투과되는 발광창 및 수광창이 마련된 하우징과, 하우징에 내장되며 상기 발광창을 통해 상기 하우징의 외부에 위치하는 시료수로 광을 발산하는 발광부와, 하우징에 내장되며 상기 수광창을 통해 입사되는 광을 검출하는 광검출기와, 발광창 및 상기 수광창의 표면에 각각 형성되며 상기 시료수 중에 함유된 미생물 또는 부유물질의 침착을 방지하기 위한 고분자막을 구비한다. 상기한 바와 같이 본 발명의 탁도 측정용 프로브에 의하면 시료수 중에 함유된 미생물, 초미립자들을 정밀하게 검출할 수 있다. 또한, 발광창 및 수광창에 형성된 고분자막은 물과 결합할 수 있는 수산화기(-OH)가 존재하지 않기 때문에 액체상태로 존재하는 배양액 내의 미생물이나 부유물질과의 상호 결합력을 감소시켜 침착현상을 방지 또는 최소화시켜 탁도 검출능력을 향상시킨다. 탁도, 탁도센서, 프로브, 고분자막, 침착, 졸겔
Abstract:
PURPOSE: A turbidity measuring probe with a macromolecule membrane modified to hydrophobic sol-gel is provided to precisely detect various sizes of particles and microorganism with one probe by building an ultraviolet diode, an infrared diode and a laser diode in a housing. CONSTITUTION: A turbidity measuring probe(10) with a macromolecule membrane modified to hydrophobic sol-gel comprises a housing(20), a light emitting part(30), a photo detector(40), and polymer layers(80). The housing comprises a light emitting window(25) through which light is transmitted and a light receiving window(27). The light emitting part is built in the housing. The light emitting part emits the light through the light emitting window to the sample water located outside the housing. The photo detector is built in the housing. The photo detector detects the light which is incident through the light receiving window. The polymer layers are respectively formed on the surfaces of the light emitting window and the light receiving window. The polymer layer prevents the suspended matter or the microorganism contained in the sample water from sinking.
