In order to facilitate understanding of the description, the same reference numerals are assigned to the same constituent elements in each drawing, and duplicate descriptions are omitted.

[제1 실시형태][First Embodiment]

도1, 도 2를 참조하여 제1 실시형태를 설명한다. 우선 도 1을 참조하여, 실시형태에 따른 연료 정화 시스템의 탱크(1)가 적용되는 선박의 종류에 대해 설명한다. 도 1은 실시형태에 따른 선박의 종류를 설명하는 모식도이다. 한편, 실시형태에 따른 탱크(1)가 저류하는 저인화점 연료의 일 예로서, LNG(Liquefied Natural Gas: 액화 천연 가스)를 들어 설명한다.A first embodiment will be described with reference to Figs. First, with reference to FIG. 1, the type of ship to which the tank 1 of the fuel purification system according to the embodiment is applied will be described. 1 is a schematic diagram illustrating a type of a ship according to an embodiment. On the other hand, as an example of the low flash point fuel stored in the tank 1 according to the embodiment, LNG (Liquefied Natural Gas) will be described.

도 1에 나타내는 바와 같이, LNG를 저류하는 탱크(1)가 적용되는 선박에는 LNG선, LNG 연료 추진선, LNG 벙커선이 포함된다.As shown in FIG. 1, the ship to which the tank 1 storing LNG is applied includes an LNG ship, an LNG fuel propulsion ship, and an LNG bunker ship.

LNG선이란, 선체 내 탱크(1)에 저류된 LNG를 화물로서 운반하는 선박이다.The LNG carrier is a ship that transports LNG stored in the tank 1 in the hull as cargo.

LNG 연료 추진선이란, 선체 내 탱크(1)에 저류된 LNG를 엔진에 공급하여 추진 연료로서 사용하는 선박이다. 예를 들어, LNG 연료 추진선에서는, 탱크(1) 내에서 액체 상태인 LNG를 펌프에 의해 엔진으로 송출하고 엔진에서 분사시켜 연소시킨다. 탱크 내에서 기화된 BOG(Boil Off Gas: 탱크로 유입되는 열로 인해 자연적으로 발생하는 메탄 가스)를 압축하여 엔진에서 분사시켜 연소시킬 수도 있다. The LNG fuel propulsion ship is a ship that supplies the LNG stored in the tank 1 in the hull to the engine and uses it as propulsion fuel. For example, in an LNG fuel propulsion ship, liquid LNG in the tank 1 is delivered to the engine by a pump, and is injected by the engine for combustion. Boil off gas (BOG) vaporized in the tank can be compressed and injected from the engine for combustion.

LNG 벙커선이란, 육상의 터미널로부터 선체 내 탱크(1)로 저류된 LNG를 LNG선 및 LNG 연료 추진선의 탱크로 공급하기 위한 선박이다.The LNG bunker ship is a ship for supplying the LNG stored in the tank 1 in the hull from the terminal on land to the tank of the LNG ship and the LNG fuel propulsion ship.

한편, LNG선, LNG 연료 추진선, LNG 벙커선의 각 명칭은, 같은 기능을 갖는 선박이라면 다른 명칭의 것도 포함한다. 또한, LNG선 및 LNG 벙커선은, 선체 내 탱크(1)에 저류된 LNG를 엔진으로 공급하여 추진 연료로서 사용하는 구성일 수도 있다. 또한, LNG 연료 추진선은, LNG를 추진 연료로서 사용하는 외에도 화물로서 운반하는 구성일 수도 있다.On the other hand, the names of LNG ships, LNG fuel propulsion ships, and LNG bunker ships include those of different names as long as they have the same function. In addition, the LNG carrier and the LNG bunker ship may have a configuration in which LNG stored in the tank 1 in the hull is supplied to the engine to be used as a propulsion fuel. In addition, the LNG fuel propulsion ship may be configured to transport LNG as a cargo in addition to using LNG as a propulsion fuel.

도 2는 제1 실시형태에 따른 연료 정화 시스템(10)의 개략적 구성을 나타내는 모식도이다.2 is a schematic diagram showing a schematic configuration of the fuel purification system 10 according to the first embodiment.

도 2에 나타내는 바와 같이, 연료 정화 시스템(10)은, 단일한 선박에 탑재되어 LNG를 저류하는 복수 개(도 2의 예에서는 2개)의 탱크(1A,1B)와, 탱크(1A)로부터 탱크(1B)로 LNG를 이동시키는 이동 경로(2)와, 이동 경로(2)에 구비되어 이동 경로(2)를 흐르는 LNG에 포함되는 불순물(D)을 제거하는 필터(6, 여과부)를 구비한다. 또한, 연료 정화 시스템(10)은, 필터(6)에 의해 불순물(D)이 제거된 LNG를 탱크(1B)로부터 탱크(1A)로 다시 돌아가게 하는 제2 이동 경로(3)를 구비한다.As shown in Fig. 2, the fuel purification system 10 is mounted on a single vessel and is equipped with a plurality of tanks 1A and 1B (two in the example of Fig. 2) storing LNG, and the tank 1A. A movement path 2 for moving LNG to the tank 1B, and a filter 6 (filter unit) provided in the movement path 2 to remove impurities D contained in the LNG flowing through the movement path 2 Equipped. Further, the fuel purification system 10 has a second movement path 3 for returning the LNG from which the impurities D has been removed by the filter 6 back from the tank 1B to the tank 1A.

탱크(1A,1B)는, 도 2에는 나타내지 않았지만, 각각의 선체의 외부로부터 LNG를 도입하는 도입로와, 저류되어 있는 LNG를 외부로 도출하는 도출로를 구비한다. 한편, 탱크(1A,1B)는 도 1에 나타낸 탱크(1)에 상당한다.Although not shown in Fig. 2, the tanks 1A and 1B include an introduction path for introducing LNG from the outside of each hull, and an outlet path for leading out stored LNG to the outside. On the other hand, the tanks 1A and 1B correspond to the tank 1 shown in FIG. 1.

이동 경로(2)는, 그 양단이 탱크(1A,1B)에 각각 삽입되며 필터(6)를 통과하는 관로(4)와, 관로(4)의 탱크(1A) 내 일단부에 구비되며 탱크(1A)에 저류되어 있는 LNG를 흡인하여 관로(4)를 통해 탱크(1B)로 도출시키는 펌프(5)를 갖는다.The movement path 2 is provided at one end in the tank 1A of the pipe 4 and a pipe 4 having both ends inserted into the tanks 1A and 1B and passing through the filter 6, respectively. It has a pump 5 which sucks LNG stored in 1A) and leads it to the tank 1B through the pipe 4.

제2 이동 경로(3)는, 그 양단이 탱크(1A,1B)에 각각 삽입되는 관로(7)와, 관로(7)의 탱크(1B) 내 일단부에 구비되며 탱크(1B)에 저류되어 있는 LNG를 흡인하여 관로(7)를 통해 탱크(1A)로 도출시키는 펌프(8)를 갖는다.The second movement path 3 is provided at one end in the tank 1B of the conduit 7 and a conduit 7 whose both ends are inserted into the tanks 1A and 1B, respectively, and is stored in the tank 1B. It has a pump (8) that sucks the existing LNG and leads it to the tank (1A) through the pipe (7).

즉, 연료 정화 시스템(10)에서는, 이동 경로(2) 및 제2 이동 경로(3)에 의해 탱크(1A)와 탱크(1B) 사이에서 LNG를 순환시킬 수 있도록 구성되어 있다.That is, in the fuel purification system 10, it is comprised so that LNG can be circulated between the tank 1A and the tank 1B by the movement path 2 and the 2nd movement path 3.

그런데, 탱크(1A,1B)에 저류되는 LNG에는, 예를 들어, LNG 정제 장소의 지리적 조건(사막 지대 등)에 따라 불순물(D)이 함유되는 경우가 있다. 불순물(D)로는, 예를 들어, 규소, 철 또는 섬유분을 포함한다. 불순물(D)은, LNG가 탱크(1A,1B)로 도입된 후, LNG와의 비중 차에 의해, 도 2에 나타내는 바와 같이, 탱크 저면(2a)에 침전된다.Incidentally, the LNG stored in the tanks 1A and 1B may contain, for example, impurities D depending on geographic conditions (desert areas, etc.) of the LNG purification site. As the impurity (D), for example, silicon, iron, or fiber powder is included. After the LNG is introduced into the tanks 1A and 1B, the impurity D is deposited on the tank bottom 2a as shown in Fig. 2 due to the difference in specific gravity with the LNG.

연료 정화 시스템(10)에서는, 불순물(D)이 섞인 LNG가 탱크(1A)로 공급되면, LNG보다 비중이 큰 불순물(D)은 탱크(1A) 안에 침전되지만, 펌프(5)가 작동하면 LNG와 함께 불순물(D)도 이동 경로(2)로 흡인된다. 이동 경로(2)로 흡인된 LNG는 필터(6)를 통과할 때에 불순물(D)이 제거되어 탱크(1B)로 도입된다. 이로써, 이동 경로(2)를 통과시키는 것만으로 탱크(1B)에 저류되는 LNG의 청정도를 쉽게 향상시킬 수가 있다.In the fuel purification system 10, when LNG mixed with impurities D is supplied to the tank 1A, impurities D having a greater specific gravity than LNG are deposited in the tank 1A, but when the pump 5 operates, LNG Together with the impurities (D) are also sucked into the movement path (2). When LNG sucked into the movement path 2 passes through the filter 6, impurities D are removed and introduced into the tank 1B. Thereby, it is possible to easily improve the cleanliness of LNG stored in the tank 1B simply by passing the movement path 2 through it.

또한, 연료 청정 시스템(10)에서는, 펌프(8)가 작동하면, 탱크(1B)에 저류되어 불순물(D)이 제거되어 있는 LNG가 제2 이동 경로(3)로 흡인되어 탱크(1A)로 되돌아간다. 이렇게 하여 이동 경로(2)와 제2 이동 경로(3)를 병용함으로써, 탱크(1A) 내 불순물(D)을 서서히 저감시킬 수 있다. 또한, 탱크(1A,1B)의 LNG 저류량을 일정하게 유지하면서 양쪽 탱크의 LNG를 정화시킬 수 있다. 이로써 이동 경로(2) 및 제2 이동 경로(3)를 통과시키는 것만으로, 탱크(1A,1B)에 저류되는 LNG의 청정도를 쉽게 향상시킬 수가 있다.In addition, in the fuel cleaning system 10, when the pump 8 is operated, LNG stored in the tank 1B and from which the impurities D have been removed is sucked into the second movement path 3 and into the tank 1A. Go back. In this way, by using the movement path 2 and the second movement path 3 together, the impurities D in the tank 1A can be gradually reduced. In addition, it is possible to purify the LNG in both tanks while keeping the LNG storage amount in the tanks 1A and 1B constant. This makes it possible to easily improve the cleanliness of LNG stored in the tanks 1A and 1B simply by passing the movement path 2 and the second movement path 3 through.

한편, LNG를 탱크(1A)로부터 탱크(1B)에 이동시키는 이동 경로(2)에 필터(6)를 구비한 구성을 예로 들었으나, LNG를 탱크(1B)로부터 탱크(1A)에 이동시키는 제2 이동 경로(3)에도 필터(6)를 구비하는 구성으로 할 수도 있다. 이 경우, 예를 들어, 탱크(1A,1B) 양쪽에 LNG가 가득할 정도로 저류되어 있는 경우에, 펌프(5,8)를 동시에 작동시켜, 탱크(1A)로부터 탱크(1B)로의 LNG 이동과, 탱크(1B)로부터 탱크(1A)로의 LNG 이동을 동시에 행함으로써, 양쪽 탱크에서 정화시킬 수가 있다. 이 구성은, 필터(6)를 구비하는 이동 경로(2)를, 탱크(1A)에서 탱크(1B)로 향하는 것과 탱크(1B)에서 탱크(1A)로 향하는 것으로 된 한 쌍으로서 구비하는 구성으로도 표현할 수 있다.On the other hand, although the structure in which the filter 6 is provided in the movement path 2 for moving LNG from the tank 1A to the tank 1B was exemplified, the first method for moving LNG from the tank 1B to the tank 1A 2 It is also possible to have a structure including the filter 6 in the movement path 3. In this case, for example, when the tanks 1A and 1B are sufficiently stored to be full of LNG, the pumps 5 and 8 are operated simultaneously to move the LNG from the tank 1A to the tank 1B and , By simultaneously moving the LNG from the tank 1B to the tank 1A, it is possible to purify in both tanks. This configuration is a configuration in which the movement path 2 provided with the filter 6 is provided as a pair of going from the tank 1A to the tank 1B and from the tank 1B to the tank 1A. Can also be expressed.

[제2 실시형태][Second Embodiment]

도 3을 참조하여 제2 실시형태를 설명한다. 도 3은 제2 실시형태에 따른 연료 정화 시스템(10A)의 개략적 구성을 나타내는 모식도이다.A second embodiment will be described with reference to FIG. 3. 3 is a schematic diagram showing a schematic configuration of a fuel purification system 10A according to a second embodiment.

도 3에 나타낸 바와 같이, 제2 실시형태의 연료 정화 시스템(10A)은, 탱크(1)가 하나라는 점, 탱크(1)에 저류되어 있는 LNG를 순환시키는 순환 경로(9)를 구비하는 점, 필터(6)가 순환 경로(9)에 구비되는 점에서 제1 실시형태와 다르다. As shown in FIG. 3, the fuel purification system 10A of the second embodiment has one tank 1 and a circulation path 9 for circulating LNG stored in the tank 1 , It differs from the first embodiment in that the filter 6 is provided in the circulation path 9.

순환 경로(9)는, 그 양단이 탱크(1)에 삽입되며 필터(6)를 통과하는 관로(11)와, 관로(11)의 탱크(1) 내 일단부에 구비되며 탱크(1)에 저류되어 있는 LNG를 흡인하여 관로(11)를 통과하도록 하는 펌프(12)를 구비한다.The circulation path 9 is provided at one end in the tank 1 of the conduit 11 and a conduit 11 having both ends inserted into the tank 1 and passing through the filter 6 A pump 12 is provided to suck the stored LNG and pass through the pipe 11.

연료 정화 시스템(10A)에서는, 불순물(D)이 섞인 LNG가 탱크(1)로 공급되면, LNG보다 비중이 큰 불순물(D)이 탱크(1) 안에 침전되지만, 펌프(12)가 작동하면 LNG와 함께 불순물(D)도 순환 경로(9)로 흡인된다. 순환 경로(9)로 흡인된 LNG는 필터(6)를 통과할 때에 불순물(D)이 제거되고 재차 탱크(1)로 도입된다. 이로써 순환 경로(9)를 통과시키는 것만으로, 단일한 탱크(1)에 저류되는 LNG의 청정도를 쉽게 향상시킬 수 있다.In the fuel purification system 10A, when LNG mixed with impurities D is supplied to the tank 1, impurities D having a higher specific gravity than LNG are precipitated in the tank 1, but when the pump 12 operates, LNG Together with the impurities (D) are also sucked into the circulation path (9). When the LNG sucked into the circulation path 9 passes through the filter 6, the impurities D are removed and introduced into the tank 1 again. This makes it possible to easily improve the cleanliness of LNG stored in a single tank 1 just by passing through the circulation path 9.
