일반적으로 선박의 운항 시, 선박 엔진용 연료유는 통상 80도 ~ 90도 정도 범위로 온도를 유지시키고 있다. 예컨대, 연료유의 온도가 80도 미만인 경우 점도는 높아져 끈적끈적한 상태가 됨으로써 연료유의 이송과 엔진 내에서의 분사를 위한 히팅이 원활하게 이루어지지 못한 문제가 발생하게 된다. 따라서, 연료유를 앞서 언급한 온도 범위로 유지시키는 설비를 적용하고 있다.
Generally, fuel oil for marine engines is maintained at a temperature in the range of 80 to 90 degrees when the ship is operated. For example, when the temperature of the fuel oil is less than 80 degrees, the viscosity becomes high and sticky, resulting in a problem that the fuel oil is not smoothly transferred for transportation and the injection in the engine. Therefore, a facility for keeping the fuel oil at the above-mentioned temperature range is applied.

상기 엔진용 윤활유 저장탱크(12)와 히터(16) 및 청정기(18)는 메인 라인(20)을 통해 순차적 연결되어 있어 윤활유가 엔진용 윤활유 저장탱크(22)로부터 히터(16)와 청정기(18)를 순차적으로 거친 후 엔진용 윤활유 저장탱크(12)로 회수되는 시스템을 구성하고 있다.The lubricant storage tank 12 for engine and the heater 16 and the purifier 18 are sequentially connected through the main line 20 so that the lubricant is supplied from the lubricant storage tank 22 for the engine to the heater 16 and the purifier 18 And then the lubricant is recovered to the lubricant storage tank 12 for the engine.

여기서, 상기 히터(16)는 청정기의 효율을 높이기 위한 윤활유의 적합한 온도 즉, 90도 ~ 95도로 형성시키기 위한 가열 기능을 제공하고, 상기 청정기(18)는 윤활유 중의 불순물을 제거하는 필터 기능을 제공한다.Here, the heater 16 provides a heating function for forming a suitable temperature of the lubricant oil to improve the efficiency of the purifier, that is, 90 to 95 degrees, and the purifier 18 provides a filter function for removing impurities in the lubricant oil do.

한편, 상기 엔진(10)은 엔진 연료 저장탱크(22)와 이송 라인(24)을 통해 연결되어 있으며, 이러한 연결로 인해 엔진 연료 저장탱크(22)에 저장된 연료유가 엔진(10)으로 이송된다.The engine 10 is connected to the engine fuel storage tank 22 through a transfer line 24 and the fuel oil stored in the engine fuel storage tank 22 is transferred to the engine 10.

또한, 상기 엔진 연료 저장탱크(22)의 내부에는 튜브 형태의 스팀 라인(26)이 설치되어 있으며, 이러한 스팀 라인(26)을 통해 순환하는 스팀의 열원을 이용하여 엔진 연료 저장탱크(22)에 저장된 연료유의 온도를 80도 ~ 90도로 유지시키고 있다.In addition, a tube-shaped steam line 26 is installed in the engine fuel storage tank 22, and a heat source of steam circulating through the steam line 26 is used to supply the engine fuel to the engine fuel storage tank 22 The temperature of the stored fuel oil is maintained at 80 to 90 degrees.

그런데, 종래기술에서는 앞서 언급한 바와 같이 튜브 형태의 스팀 라인(26)을 엔진 연료 저장탱크(22)에 설치하여야 하는 설치상에 문제와, 스팀이 생성되는 설비와 엔진(10) 간에 거리가 먼 경우, 스팀 라인(26)을 엔진 연료 저장탱크(22)로 이끌어와야 하는 라인 설계상에 문제가 있다. 특히, 고온인 스팀의 사용으로 인해 스팀 라인(26)의 부식과 열변형 등으로 인하여 유지 관리 작업은 물론, 보수 비용이 많이 소요되는 문제가 있었다.
However, in the conventional art, there is a problem in installation that the tube type steam line 26 should be installed in the engine fuel storage tank 22, and a problem in which the distance between the facility where the steam is generated and the engine 10 There is a problem in the line design in which the steam line 26 must be led to the engine fuel storage tank 22. In particular, due to the use of high temperature steam, corrosion and thermal deformation of the steam line 26 have caused a problem of requiring a maintenance operation as well as a high maintenance cost.

아래에서는 본 발명에 따른 선박용 엔진 윤활유의 폐열을 이용한 엔진 연료유 온도 유지시스템에 대한 바람직한 실시 예를 상세히 설명한다.Hereinafter, preferred embodiments of an engine fuel oil temperature maintenance system using waste heat of marine engine lubricating oil according to the present invention will be described in detail.

도 2에서는 본 발명에 따른 선박용 엔진 윤활유의 폐열을 이용한 엔진 연료유 온도 유지시스템을 보여주고 있다.FIG. 2 shows an engine fuel oil temperature maintenance system using waste heat of a marine engine lubricating oil according to the present invention.

도면에서 보듯이, 엔진(10)과 엔진용 윤활유 저장탱크(12) 간에는 순환 라인(14)을 통해 연결되어 엔진용 윤활유 저장탱크(12)에 저장된 윤활유가 엔진(10)을 순환하고 엔진용 윤활유 저장탱크(12)로 회수된다.The lubricating oil stored in the lubricating oil storage tank 12 for engine circulation is circulated between the engine 10 and the lubricating oil storage tank 12 through the circulation line 14 to circulate the engine 10, And is returned to the storage tank 12.

상기 엔진용 윤활유 저장탱크(12)는 메인 라인(20)을 통해 히터(16)와 청정기(18)를 순차적으로 연결하고 있다. 그에 따라 엔진용 윤활유 저장탱크(12)의 윤활유는 종래와 마찬가지로 히터(16)와 청정기(18)를 거쳐 엔진용 윤활유 저장탱크(12)로 회수된다. The lubricant storage tank 12 for the engine sequentially connects the heater 16 and the purifier 18 through the main line 20. The lubricating oil of the engine lubricating oil storage tank 12 is recovered to the engine lubricating oil storage tank 12 through the heater 16 and the purifier 18 as in the conventional manner.

한편, 상기 엔진(10)은 연료유가 저장된 엔진 연료 저장탱크(22)와 이송 라인(24)을 통해 연결되어 있으며, 그 이송 라인(24) 상에는 펌프(P3)가 설치되어 엔진 연료 저장탱크(22)에 저장된 연료유를 엔진(10)으로 이송시키는 기능을 담당하게 된다.The engine 10 is connected to an engine fuel storage tank 22 in which fuel oil is stored through a transfer line 24. A pump P3 is installed on the transfer line 24 to connect the engine fuel storage tank 22 To the engine 10, as shown in FIG.

여기서, 본 발명은 청정기(18)와 엔진용 윤활유 저장탱크(12)를 연결하는 메인 라인(20) 상에 열교환기(30)가 설치되며, 이러한 열교환기(30)에는 엔진 연료 저장 탱크(22)를 순환하는 순환라인(32)이 열교환기(30)의 열교환부와 열교환이 이루어질 수 있는 상태로 설치되어 있다.In the present invention, a heat exchanger 30 is installed on a main line 20 connecting a purifier 18 and a lubricant storage tank 12 for an engine. The engine fuel storage tank 22 ) Is installed in a state where heat exchange with the heat exchanger of the heat exchanger (30) can be performed.

따라서, 상기 엔진용 윤활유 저장탱크(12)에 저장된 윤활유는 연료유 순환 펌프(P1)에 의해 펌핑 되어 히터(16)를 통과하게 되고, 히터(16)를 통과한 윤활유는 종래와 마찬가지로 90도 ~ 95도를 형성하는 온도 상태로 청정기(18)를 거치게 된다. Therefore, the lubricating oil stored in the engine lubricating oil storage tank 12 is pumped by the fuel oil circulation pump P1 and passes through the heater 16. The lubricating oil passed through the heater 16 is, And passes through the purifier 18 at a temperature of 95 degrees.

위와 같이 청정기(18)를 통과한 윤활유는 엔진용 윤활유 저장탱크(12)로 회수되기 직전 열교환기(30)의 열교환부(34)를 지나가게 되는데, 이때 열교환기(30)의 열교환부(34)로 흐르는 윤활유와 열교환이 이루어질 수 있도록 엔진 연료 저장탱크(22)의 순환라인(32)이 열교환기(30)를 지나가도록 설치되어 있어서, 연료유 순환 펌프(P3)에 의해 순환 라인(32)을 따라 흐르는 연료유는 열교환부(34)를 지나가는 윤활유와 열교환이 이루어지게 된다.The lubricant that has passed through the cleaner 18 passes through the heat exchanger 34 of the heat exchanger 30 immediately before being recovered to the lubricant storage tank 12 for the engine. At this time, the heat exchanger 34 The circulation line 32 of the engine fuel storage tank 22 is provided so as to pass through the heat exchanger 30 so that the heat exchange with the lubricating oil flowing through the circulation line 32 can be performed by the fuel oil circulation pump P3, The heat exchange with the lubricating oil passing through the heat exchanging unit 34 is performed.

그로 인해 연료유는 80도 ~ 90도 범위의 온도를 형성하는 상태로 회수되며, 이러한 반복적인 열교환시스템으로 인해 엔진 연료유 저장탱크(22)에 저장된 연료유는 80도 ~ 90도 온도 상태로 유지될 수 있게 된다.  As a result, the fuel oil is recovered in a state of forming a temperature in the range of 80 to 90 degrees. Due to this repetitive heat exchange system, the fuel oil stored in the engine fuel oil storage tank 22 is maintained at a temperature of 80 to 90 degrees .

따라서, 종래에는 튜브 형태의 스팀 라인을 엔진 연료유 저장탱크에 감아야 하는 설치상에 문제, 스팀이 생성되는 설비가 엔진으로부터 거리가 먼 경우 스팀 라인을 엔진 연료 저장탱크로 이끌어와야 하는 라인 설계상에 문제, 스팀의 사용으로 인한 부식 및 열변형 문제와 그로 인해 수반되는 유지 관리 작업 과다 및 보수 비용이 많이 소요되는 문제가 있었으나, 본 발명에서는 엔진용 윤활유 저장탱크와 청정기를 연결하는 메인 라인 상에 설치되는 열교환기와, 이 열교환기를 지나가도록 엔진 연료유 저장탱크에 설계되는 순환 라인만으로 연료유의 적정 온도를 유지시킬 수 있게 됨으로써, 가장 큰 문제였던 설비 설치 작업과 설치 비용을 절감할 수 있게 되고, 아울러 유비 보수 및 관리 작업이 대폭 줄어들어 관리가 신속 간편함을 제공받을 수 있게 된다.Accordingly, there is a problem in the conventional installation that the tube type steam line should be wound around the engine fuel oil storage tank, the line design in which the steam line should be led to the engine fuel storage tank when the steam generating facility is distant from the engine There is a problem that corrosion and thermal deformation due to the use of steam, excessive maintenance work accompanying with the maintenance work, and maintenance cost are required. However, in the present invention, there is a problem in that the lubricant storage tank and the cleaner It is possible to maintain the proper temperature of the fuel oil only by the heat exchanger installed and the circulation line designed in the engine fuel oil storage tank so as to pass through the heat exchanger, thereby making it possible to reduce the facility installation work and installation cost, which were the greatest problems, The maintenance and management work is greatly reduced, so management can be provided quickly and easily. do.
