Description

선박용 저유황 해양가스오일의 연료유 변경을 위한 점도정보표시장치{Viscosity data display apparatus of LSMGO using vessel} Technical Field [0001] The present invention relates to viscosity information display apparatus for changing the fuel oil of a marine low-sulfur marine gas oil,

본 발명은 선박용 저유황 해양가스오일의 연료유 변경을 위한 점도정보표시장치에 관한 것으로서 더욱 상세하게는 엔진 인렛에 설치되는 점도 컨트롤러로부터 인지된 점도정보들이 분할되도록 아이솔레이터를 통해 두 개의 출력신호로 분리하여 제어패널 상에서 온도 조절에 따른 점도변화를 실시간으로 확인할 수 있는 점도정보표시장치에 관한 것이다.
The present invention relates to a viscosity information display apparatus for changing the fuel oil of a low-sulfur marine gas oil for marine use, and more particularly, to a viscosity information display apparatus for separating viscous information from a viscosity controller installed in an engine inlet, To a viscosity information display device capable of real-time checking of a viscosity change on the control panel according to temperature control.

일반적으로, 선박 엔진 구동을 위한 연료로서 벙커유가 일반적으로 채택되어 왔다. 벙커유는 연소과정에서 많은 양의 아황산가스를 배출하고, 스모그의 원인인 산화질소 가스를 배출하는 등 환경오염의 주범으로 지적되어 왔다. In general, bunker oil has been generally adopted as a fuel for driving a marine engine. Bunker oil has been pointed out as a major cause of environmental pollution such as discharging a large amount of sulfur dioxide gas during combustion and discharging nitrogen oxide gas which is the cause of smog.

이에 따라, 최근 유럽 등 각국에서는 근해를 항해하는 선박의 경우 동력원으로서 벙커유를 사용하는 대신에 황이나 유해물질의 함유량이 비교적 적은 해양가스오일(Marine Gas Oil)를 사용할 것을 권유하고 있다. 그러나 해양가스오일(Marine Gas Oil)는 벙커유에 비해 점도가 극히 낮아 일반 선박용 엔진에 연료로서 바로 사용할 수 없으며, 따라서 연료로 사용하기에 적합한 온도로 냉각시킨 후 사용해야만 한다.Accordingly, in recent years, in countries such as Europe, it is recommended to use marine gas oil in which the content of sulfur or harmful substances is relatively small, instead of using bunker oil as a power source in a ship navigating offshore. Marine gas oil, however, is extremely low in viscosity compared to bunker oil and can not be used as fuel for general marine engines. Therefore, it should be cooled down to a temperature suitable for use as fuel.

한편, 선박의 메인엔진(Main Engine) 및 발전기(Generator Engine)에 사용되는 연료는 해양디젤오일(Marine Diesel Oil)나 중연료오일(Heavy Fuel Oil)이 주류를 이룬다. 이러한 연료 중 해양디젤오일은 가열하지 않고 그냥 사용하는 반면, 중연료오일은 히터(Heater)를 통해 가열하여 메인엔진 또는 발전기에서 요구되는 점도를 유지하여 사용하고 있다. On the other hand, the fuel used for the main engine and the generator engine of the ship are mainly composed of marine diesel oil and heavy fuel oil. Of these fuels, marine diesel oil is used without heating, while heavy fuel oil is heated through a heater to maintain the viscosity required by the main engine or generator.

일례로서, 종래 기술의 선박용 냉각기를 이용한 저유황 해양가스오일 공급시스템에 대해 개략적으로 살펴보면 다음과 같다.As an example, a low-sulfur marine gas oil supply system using a conventional marine cooler will be briefly described below.

도 1에 도시된 바와 같이, 종래의 저유황 해양가스오일 공급시스템은 해양디젤오일(MDO)과 중연료오일(HFO)을 메인엔진(ME)(10) 혹은 발전기 엔진(도시 안됨)에 공급하기 위한 것으로서, 그 시스템 구성은 각각의 저유황 해양가스오일(LSMGO) 및 해양디젤오일(MDO)을 각각 해당 탱크에 저장하는 엘에스엠지오탱크(22) 및 엠디오탱크(24)와, 저유황 중연료오일(LSHFO) 및 중연료오일(HF0)을 각각 해당 탱크에 저장하는 엘에스에이치에프오탱크(32) 및 에이치에프오일탱크(34)가 구비되고, 이들 탱크(22)(24)(32)(34)로부터 메인엔진(10)까지 연장되는 유로가 구비되며, 이들 유로 상에 각각의 공급펌프(41), 연료유에 섞여 있는 불순물을 제거하기 위한 오토필터 및 바이패스필터(42), 연료의 유량을 확인하기 위한 플로우미터(43), 냉각기(45), 순환펌프(46), 히터(47), 인렛필터(48) 및 점도컨트롤러(50) 등이 포함되어 설치된다. 부호 44는 플로우미터(43)와 냉동기(45) 사이에 설치되는 리턴파이프(Return pipe)로서 오버플로우탱크와 연결된다.1, a conventional low sulfur marine gas oil supply system supplies marine diesel oil (MDO) and medium fuel oil (HFO) to a main engine (ME) 10 or a generator engine (not shown) The system configuration includes an SLM tank 22 and an MDi tank 24 for storing respective low-sulfur marine gas oil (LSMGO) and marine diesel oil (MDO) in the respective tanks, a low- An LF oil tank 32 and an HF oil tank 34 that store the oil LSHFO and the heavy fuel oil HF0 in the respective tanks are provided and these tanks 22, 24, 32, 34 And the flow path extending from the main engine 10 to the main engine 10 are provided with the respective supply pumps 41, an auto filter and a bypass filter 42 for removing impurities mixed in the fuel oil, The flow meter 43, the cooler 45, the circulation pump 46, the heater 47, the inlet filter 48, A viscosity controller 50 and the like. Reference numeral 44 denotes a return pipe provided between the flow meter 43 and the freezer 45 and connected to the overflow tank.

이들 구성에 따른 해당 탱크로부터 메인엔진(10)으로 연료가 공급되는 경로를 살펴보면 다음과 같다.A path through which the fuel is supplied from the corresponding tank to the main engine 10 according to these configurations is as follows.

먼저, 메인엔진(10)으로의 연료공급 경로를 살펴보면, 엘에스엠지오탱크(22) 또는 엘에스에이치에프오탱크(32)에서 공급펌프(41)를 거쳐 순환펌프(46) 및 히터(47)를 경유하고, 이때 연료 내부의 이물질은 오토필터 및 바이패스필터(42)를 통해 오버플로우탱크로 연료가 배출되며, 계속해서 점도컨트롤러(50)를 거친 후 메인엔진(10)으로 공급된다.First, referring to the fuel supply path to the main engine 10, the fuel is circulated through the circulation pump 46 and the heater 47 via the supply pump 41 in the SLM tank 22 or the LNFC tank 32 At this time, the foreign matter in the fuel is discharged to the overflow tank through the auto filter and the bypass filter 42, and then supplied to the main engine 10 after passing through the viscosity controller 50.

이러한 구성을 갖는 종래의 저유황 해양가스오일 공급시스템은 엔진업체 권고사항에 따라 저유황 해양가스오일(LSMGO) 사용을 위해 냉각기가 설치되고, 냉각기(CHILLER)에 의해 냉각된 저유황 해양가스오일(LSMGO)의 온도 조절을 통하여 엔진업체에서 권고하는 엔진 입구에서의 점도를 만족하도록 연료유(FO)의 변경이 이루어지고 있다. A conventional low sulfur marine gas oil supply system having such a configuration is provided with a cooler installed for the use of low sulfur marine gas oil (LSMGO) and a low sulfur marine gas oil cooled by a cooler (CHILLER) LSMGO) is changing the fuel oil (FO) to meet the viscosity at the engine inlet recommended by the engine manufacturer.

또한, 스펙(SPEC)에 따라 엔진 입구에서의 점도는 점도 컨트롤러(viscosity controller)에 의해 아래 3가지 방향으로 엔진 입구에 유입되는 오일의 점도를 인지하게 된다. 즉, 점도 로컬지시(Viscosity local indication), 점도 원격지시(Viscosity remote indication), 점도 로컬과 점도 원격지시(Viscosity local and remote indication)를 인지하게 된다.In addition, according to SPEC, the viscosity at the engine inlet is perceived by the viscosity controller as the viscosity of the oil flowing into the engine inlet in the following three directions. That is, it recognizes a viscosity local indication, a viscosity remote indication, a viscosity local and a remote indication.

그러나 통상적으로 점도 컨트롤러와 냉각기는 연료유 유닛으로서 유사한 위치에 설치되어 로컬에 표시되는 점도로 그 값을 알 수 있는 경우가 있으나, 냉각기의 용량에 따라 다른 데크(DECK)에 설치되어 점도 확인이 불가한 경우가 있었다.However, in general, the viscosity controller and the cooler are installed at similar positions as the fuel oil unit, and the viscosity can be locally displayed. However, it is installed in a different deck depending on the capacity of the cooler, There was one case.

또한, 점도 컨트롤러의 원격 지침만이 적용 될 경우 연료유 변경 시 엔진에서의 점도 확인이 로컬에서는 불가하여 무전으로 정보를 주고받았다.Also, when only the remote instructions of the viscosity controller are applied, it is impossible to check the viscosity in the engine when the fuel oil is changed.

따라서 연료유 변경 시 엔진마커(ENGINE MAKER)에서 요구하는 분당 2도씨 조절을 수행하는 동안 메인엔진 인렛(INLET)에서의 점도의 실시간 확인이 불가한 경우, 점도 확인을 위한 무전과 오일 점도의 급 변화에 대한 응급대응 불가로 인하여 연료유 변경 시간이 증가 하는 문제점이 발생하였다.
Therefore, when real-time confirmation of the viscosity at the main engine inlet (INLET) can not be performed during the execution of the adjustment of 2 degrees per minute required by the engine marker (ENGINE MAKER) when changing the fuel oil, There was a problem that the change time of the fuel oil was increased due to the inability to respond to the emergency response.

따라서 본 발명은 상기한 종래의 문제점들을 해결하기 위해 이루어진 것으로서, 그 목적은 엔진 인렛에 설치되는 점도 컨트롤러로부터 인지된 점도정보들이 분할되도록 아이솔레이터를 통해 두 개의 출력신호로 분리하여 엔진제어룸(ECR)과 냉각기의 제어패널 상에서 온도 조절에 따른 점도변화를 실시간으로 확인할 수 있도록 하는 선박용 저유황 해양가스오일의 연료유 변경을 위한 점도정보표시장치를 제공하는데 있다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide an engine control room (ECR), which is separated into two output signals through an isolator so that viscosity information, And a visibility information display device for changing the fuel oil of a low-sulfur marine gas oil for a ship, which allows a change in viscosity of the ship to be monitored in real time on a control panel of a cooler.
