Description

선박 조수기용 유동 방지 구조Flow prevention structure for ship's water tanker
본 발명은 선박 조수기용 유동 방지 구조에 관한 것으로서, 보다 상세하게는 증발기 내부에 채워진 해수의 유동에 의하여 담수의 생산량이 감소하거나 증발기의 해수와 응축기의 담수가 혼합되는 것을 방지할 수 있는 선박 조수기용 유동 방지구조에 관한 것이다.The present invention relates to a flow preventing structure for a marine water tanker, and more particularly, for a marine water tanker that can prevent the production of fresh water by the flow of seawater filled inside the evaporator, or to prevent the fresh water of the evaporator and the fresh water of the condenser. It relates to a flow prevention structure.
일반적으로 선박의 엔진열로 담수를 제조하는 선박용 조수기는 엔진열로 해수를 증발시키는 증발기 1개와 증발된 물을 담수로 만드는 응축기 1개로 이루어진다. 이러한 조수기의 생산량을 증대시키기 위해서는 1개로 이루어진 증발기의 용적을 증대시켜야 하기 때문에 보다 큰 설치 면적이 요구된다. In general, a marine water tanker for producing fresh water using the engine heat of the ship is composed of one evaporator for evaporating seawater with engine heat and one condenser for making fresh water from the evaporated water. In order to increase the production of such a water heater, a larger installation area is required because the volume of one evaporator must be increased.
한편, 육상용의 경우 다중 효용 담수(MED; Multi-Effect Desalinator) 방식으로 설치 면적은 동일하게 하면서 복수개의 증발기를 상하로 설치하여 담수 생산량을 증가시키는 구조를 이루게 된다.On the other hand, in the case of land use, the multi-effect fresh water (MED; Multi-Effect Desalinator) method to achieve the structure to increase the fresh water production by installing a plurality of evaporators up and down while the same installation area.
그러나 해상의 선박용 조수기는 복수개의 증발기를 상하로 설치하는 경우, 선박용 조수기의 무게 중심이 높아지므로 선박의 유동 시, 상부의 증발기 해수의 유동이 심하게 발생하여 담수 생산량 감소와 동시에 생산된 담수에 해수가 혼합되는 문제가 발생될 수 있기 때문에 증발기를 1개로만 제조하는 실정이다. However, when the marine water tanker is installed with a plurality of evaporators up and down, the center of gravity of the marine water tanker increases, so that the flow of the upper evaporator seawater occurs badly during the flow of the vessel, reducing the freshwater production and at the same time the fresh water produced Since the problem of mixing may occur, only one evaporator is manufactured.
하지만, 상기와 같은 문제점을 해소하고자 조수기에 1개의 증발기만을 적용하게 되면 선박 기관실의 협소한 공간에도 불구하고 조수기의 생산량을 증대시키기 위하여 증발기의 체적을 증가시켜야 하므로 선박의 레이아웃 설계에 어려움이 따르는 문제점을 내포한다.However, if only one evaporator is applied to the water tank to solve the above problems, it is difficult to design the layout of the ship because the volume of the evaporator must be increased to increase the output of the water tank despite the small space of the ship engine room. It involves the following problems.
본 발명은 상술한 문제점을 해결하기 위하여 창출된 것으로, 본 발명의 목적은 증발기 상부에 복수개의 다각형의 셀을 갖는 유동 방지 막을 설치하여 증발기 상부의 해수가 각 셀 공간 내부에서만 유동하도록 함으로써 증발시 내부에서의 해수 유동을 최소화 하는데 있다.The present invention was created in order to solve the above problems, an object of the present invention is to install a flow preventing membrane having a plurality of polygonal cells on the top of the evaporator to allow the seawater on the top of the evaporator to flow only inside each cell space during evaporation To minimize seawater flow.
이러한 목적을 달성하기 위한 본 발명의 실시예에 따른 선박용 조수기는 내부에 적어도 1개 이상의 증류실을 구비하는 본체 및 상기 증류실 중 어느 1개의 증류실에 설치되는 증발기를 포함하고, 상기 증발기와 열교환하도록 해수가 공급되며, 상기 해수가 수용되는 수용부에 설치되는 유동 방지 막을 포함하는 것을 특징으로 한다. Ship water tank according to an embodiment of the present invention for achieving this object includes a main body having at least one distillation chamber therein and an evaporator installed in any one of the distillation chamber, heat exchanger with the evaporator Sea water is supplied so as to, characterized in that it comprises a flow preventing membrane installed in the receiving portion for receiving the sea water.
또한, 상기 유동 방지 막은 복수개의 직립형 격벽으로 이루어지고, 선박의 유동이 발생할 때 해수가 상기 격벽 사이에 형성되는 각각의 셀 내부에서만 유동할 수 있는 높이로 형성되는 것을 특징으로 한다.In addition, the flow preventing membrane is composed of a plurality of upright partitions, characterized in that formed when the flow of the vessel is a height that can only flow inside each cell formed between the partitions.
또한, 상기 셀의 횡단면 형상은 다각형으로 이루어지는 것을 특징으로 한다.In addition, the cross-sectional shape of the cell is characterized in that consisting of a polygon.
아울러, 상기 격벽의 높이 방향에 대하여 수직 방향으로 가로지르는 수평판이 형성되고, 상기 수평판 상에는 복수개의 유동 홀이 형성되는 것을 특징으로 한다.In addition, the horizontal plate transverse to the vertical direction with respect to the height direction of the partition wall is formed, characterized in that a plurality of flow holes are formed on the horizontal plate.
본 발명의 일 실시예에 따른 선박 조수기용 유동 방지 구조는, 선박 운항 때 파도에 의하여 선체가 롤링, 히빙 등의 유동이 발생함에도 불구하고, 조수기 내부에 채워진 해수의 쏠림을 막아 증발기의 해수와 응축기의 응축수가 섞이는 현상을 방지할 수 있다.According to an embodiment of the present invention, the flow preventing structure for the ship's water tanker prevents the seawater of the evaporator from being drawn by the seawater, even though the hull is rolled or heaved by the waves during the ship's operation. The condensate of the condenser can be prevented from mixing.
또한, 선박의 유동에 의하여 해수가 해수 및 응축수가 혼합되는 것을 방지할 수 있으므로 대용량의 응축수 생산이 필요 시 복수개의 증발기를 상하로 적층 설치하기 용이하다.In addition, since seawater and condensed water can be prevented from being mixed by the flow of the vessel, when a large amount of condensed water is required, it is easy to stack a plurality of evaporators up and down.

Here, as illustrated in FIG. 4, a horizontal plate 440 is formed to cross the vertical direction with respect to the height direction of the flow preventing membrane 430, and a plurality of flow holes 441 are formed in the horizontal plate 440. As a result, the seawater may flow upward through only the water vapor 441 which flows downward and vaporizes.
전술한 바와 같이 이루어진 본 발명의 일 실시예에 의한 선박 조수기용 유동 방지 구조에 따르면 선박이 운항 중 선체에 롤링(rolling; 좌우 유동), 히빙(heaving; 상하 유동) 등의 유동이 발생하더라도 증발기(110) 상부의 해수(W1)가 복수개의 셀(131) 내부로부터 외부로의 유동이 억제되므로 불규칙 유동이 방지될 뿐만 아니라, 증발기(110) 상부 응축기(140)의 응축수(W2)와 혼합되는 것이 방지된 다.According to the flow preventing structure for a ship water conditioner according to an embodiment of the present invention made as described above, even if a flow occurs, such as rolling (left and right flow), heaving (heaving (up and down flow)) in the hull during the operation of the evaporator ( 110, the upper sea water (W1) is suppressed because the flow from the inside of the plurality of cells 131 to the outside is not only prevented irregular flow, but also mixed with the condensed water (W2) of the upper condenser 140 of the evaporator (110). Prevented.
따라서, 선박의 유동에 구애받지 않고 복수개의 증발기를 상하로 설치할 수 있으므로 조수기가 설치되는 면적이 감소함과 동시에 많은 양의 담수를 생산할 수 있게 된다. 아울러, 상기 증발기(110)는 선박용 LNG연료 탱크, LPG 연료 탱크, 해상의 DME(Dimethyl ether) 생산 공정 등 모든 해양 조건에서 운항 및 운용되는 선박의 유체 유동 방지를 위한 장치에 적용될 수 있다.Therefore, since a plurality of evaporators can be installed up and down regardless of the flow of the vessel, it is possible to produce a large amount of fresh water while reducing the area in which the water heater is installed. In addition, the evaporator 110 may be applied to an apparatus for preventing fluid flow of a vessel that is operated and operated in all marine conditions such as a marine LNG fuel tank, an LPG fuel tank, and an offshore dimethyl ether (DME) production process.
이상으로 본 발명에 관한 바람직한 실시 예를 설명하였으나, 본 발명은 상기 실시 예에 한정되지 아니하며, 본 발명의 실시 예로부터 당해 발명이 속하는 기술 분야에서 통상의 지식을 가진 자에 의한 용이하게 변경되어 균등하다고 인정되는 범위의 모든 변경을 포함한다.Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and easily changed and equalized by those skilled in the art from the embodiments of the present invention. It includes all changes to the extent deemed acceptable.
