Description
본 발명은 연료유 재사용 장치에 관한 것으로, 보다 상세하게는 내연기관에서 연소되지 못하고 버려지는 연료유 중 사용 가능한 연료를 재활용할 수 있는 시스템에 관한 것이다.The present invention relates to a fuel oil reuse apparatus, and more particularly, to a system capable of recycling usable fuel among fuel oils that cannot be burned in an internal combustion engine and discarded.
도 1은 종래 선박용 엔진의 연료유 시스템의 다이어그램을 도시한 것으로, 1 shows a diagram of a fuel oil system of a conventional marine engine,
일반적으로 선박용 엔진의 연료유 이송 시스템을 살펴보면, 연료탱크의 연료유는 이송펌프(Transfer Pump)를 사용하여 필요한 만큼의 연료유를 세틀탱크(Settling Tank)로 이송된다. 대개 이러한 세틀탱크(Settling Tank)내의 연료유 양은 항상 정해진 높이를 유지하게 된다.In general, looking at the fuel oil transfer system of the marine engine, the fuel oil in the fuel tank is transferred to the settling tank (Settle Tank) as much fuel oil as necessary using a transfer pump (Transfer Pump). Usually the amount of fuel in these settling tanks will always be at a fixed height.
이때 HFO(Heavy Fuel Oil)과 같이 불순물이 포함된 저질유의 경우에는 청정기(Purifier)를 사용하여 엔진에 사용할 수 있을 정도로 연료유내 불순물 및 수분을 완전히 제거해 주게 된다.At this time, in the case of low quality oil containing impurities such as HFO (Heavy Fuel Oil), a purifier is used to completely remove impurities and water in the fuel oil so that it can be used in an engine.
이렇게 청정기(Purifier)에서 불순물이 제거된 깨끗한 연료유는 서비스탱크(Service Tank)로 보내고, 걸러진 불순물은 슬러지탱크(Sludge Tank)에 모아놓게 된다.The clean fuel oil in which the impurities are removed from the purifier is sent to the service tank, and the filtered impurities are collected in the sludge tank.
사용 준비된 서비스탱크(Service Tank)의 연료유는 공급펌프(Supply Pump)로 펌핑되어 순환펌프(Circulating Pump) 혹은 부스터 펌프(Booster Pump)로 승압된 후, 점도조절기(Viscosity Controller)를 통하여 엔진의 노즐에서 분사되기 적합하게 엔진으로 공급된다.The fuel oil in the service tank ready for use is pumped by the supply pump, boosted by the circulating pump or booster pump, and then the nozzle of the engine through the viscosity controller. It is supplied to the engine to be injected from the engine.
이때, 서비스탱크(Service Tank)로부터 엔진을 향해 공급되는 연료유는 엔진에서 필요로 하는 연료양보다 충분히 많게 공급하고 잔여분은 믹싱탱크(Mixing Tank)로 되돌아와 서비스탱크(Service Tank)에서 온 연료유와 섞이어 다시 엔진으로 가는 순환방식이 이루어지게 된다.At this time, the fuel oil supplied from the service tank toward the engine is supplied more than the amount of fuel required by the engine, and the remainder is returned to the mixing tank to return the fuel oil from the service tank. Mixed with and back to the engine is achieved.
또한, 선박용 엔진의 연료유 이송 시스템에는 시스템의 고장이나 오작동에 의하여 연료유의 이송 시 연료탱크 혹은 세틀탱크(Settling Tank)가 넘쳤을 때 공기관을 통하여 갑판으로 연료유가 넘쳐나는 것을 방지할 목적으로 오버플로우탱크(Overflow Tank)가 포함하여 설치된다.In addition, the fuel oil transfer system of the marine engine is overflowed to prevent fuel oil from overflowing to the deck through the air pipe when the fuel tank or settling tank overflows during the transfer of fuel oil due to a failure or malfunction of the system. The tank includes an overflow tank.
또한, 엔진이나 연료유 시스템 내 깨끗한 곳에서 누설된 오염되지 않은 연료유를 모아두었다가 이송하여 재사용하도록 하는 드레인탱크(Drain Tank)가 포함하여 설치된다.In addition, the drain tank (Drain Tank) is installed to collect the uncontaminated fuel oil leaked in a clean place in the engine or fuel oil system for transport and reuse.
또한, 연료유 시스템 내에서 누설 혹은 배출된 오염된 연료유를 모아두는 목적으로 폐연료유탱크(Waste Oil Tank)가 포함하여 설치된다.In addition, a waste fuel oil tank (Waste Oil Tank) is installed to collect contaminated fuel oil leaked or discharged in the fuel oil system.
또한, 청정기(Purifier)에서 걸러진 불순물이 섞인 연료유를 모아두는 목적으로 슬러지탱크(Sludge Tank)가 포함하여 설치된다.In addition, a sludge tank is installed to collect fuel oil mixed with impurities filtered by a purifier.
상기와 같은 탱크들에서 재사용이 불가능한 연료유는 소각기(Incinerator) 혹은 보일러에서 태워버리거나 항만 연결설비(Shore Connection)를 통하여 항만의 수거설비로 배출하게 된다.Fuel oil that cannot be reused in such tanks is burned in an incinerator or a boiler, or discharged to a port collection facility through a Shore Connection.
이상과 같은 선박용 엔진의 연료유 시스템에 있어서 엔진에서 연소되지 못하고 다량으로 버려지는 연료유들에는 아래와 같은 항목이 있다.In the fuel oil system of the marine engine as described above, the fuel oils that are not burned by the engine and are discarded in a large quantity include the following items.
첫째, 연료유 공급블록(Drain from High Pressure Block)으로부터의 배유, 즉 연료유 주입펌프로부터 노즐까지 연료유가 이송되어 고압으로 분사되기 위하여 배유 되어지는 연료유 (D1 : 도 1참조)First, the fuel oil that is drained from the drain oil from the Drain from High Pressure Block, that is, the fuel oil is transported from the fuel oil injection pump to the nozzle to be injected at high pressure (D1: see FIG. 1).
둘째, 연료유 주입펌프(Drain from Injection Pump)로부터의 배유, 즉 연료주입펌프 내의 플런저와 바렐의 간극 사이에서 윤활된 후 배유되어 버려지는 연료유 (D2 : 도 1참조)Second, the oil from the drain from injection pump, that is, the fuel oil that is drained after being lubricated between the gap between the plunger and the barrel in the fuel injection pump (D2: see FIG. 1).
셋째, 엔진블록(Drain from Engine Block)으로부터의 누유, 즉 엔진의 보수 유지 또는 문제 발생 시 누유되어 버려지는 연료유 (D3 : 도 1참조)Third, the oil leaked from the drain from the engine block, that is, the fuel oil that is leaked when the engine is maintained or maintained. (D3: see FIG. 1)
넷째, 연료유 세이프티 필터(Drain from FO Safety Filter)로부터의 배유, 즉 연료필터를 청정하기 위하여 작동 시킨 후 슬러지와 함께 배출되는 연료유Fourth, the oil discharged from the Drain from FO Safety Filter, that is, the fuel oil discharged together with the sludge after operating to clean the fuel filter.
다섯째, 연료유 세이프티 필터 트레이(Drain from FO Safety Filter Tray)로부터 누유, 즉 연료유 세이프티 필터 보수 유지 또는 문제 발생 시 누유되어 버려지는 연료유 (D5 : 도 1참조)Fifth, fuel oil that is leaked from the drain from FO Safety Filter Tray, that is, when the fuel oil safety filter is maintained or has a problem (D5: see FIG. 1).
이상과 같이, 종래 선박용 엔진의 연료유 시스템의 경우, 상기 연료유 공급블록(2:High Pressure Block), 연료유 주입펌프(1:Injection Pump), 엔진블록(3:Engine Block), 연료유 세이프티 필터(4:FO Safety Filter) 및 연료유 세이프티 필터 트레이(5:FO Safety Filter Tray)를 통하여 버려지는 모든 연료유에 대하여 상기 슬러지탱크(Sludge Tank) 혹은 폐연료유탱크(Waste Oil Tank)에 배출시켜 버려지게 되었다.As described above, in the case of a fuel oil system of a conventional marine engine, the fuel oil supply block (2: High Pressure Block), fuel oil injection pump (1: Injection pump), engine block (3: Engine Block), fuel oil safety All fuel oil discarded through a filter (4: FO Safety Filter) and a fuel oil safety filter tray (5: FO Safety Filter Tray) is discharged to the sludge tank or a waste oil tank. It was abandoned.
하지만, 상기 엔진블록(3:Engine Block), 연료유 세이프티 필터(4:FO Safety Filter) 및 연료유 세이프티 필터 트레이(5:FO Safety Filter Tray)를 통하여 버려지는 연료유의 경우에는 윤활유, 물 등 불순물이 다량으로 섞인 연료유(D3;D4;D5)로서 이러한 연료유는 재사용이 불가하여 상기 슬러지탱크(Sludge Tank) 혹은 폐연료유탱크(Waste Oil Tank)에 담아두도록 한 것은 당연구조라 할 수 있겠으나, 상기 연료유 공급블록(2:High Pressure Block)과 연료유 주입펌프(1;Injection Pump)를 통하여 버려지는 연료유의 경우에는 깨끗한 연료유(D1;D2)에 해당하는 것으로 이에 대한 재사용에 관한 고려가 전혀 이루어지지 못하여 많은 양의 연료유가 소모되고 있었다.However, in the case of the fuel oil discarded through the engine block (3: Engine Block), the fuel oil safety filter (4: FO Safety Filter) and the fuel oil safety filter tray (5: FO Safety Filter Tray), impurities such as lubricating oil and water As the fuel oil (D3; D4; D5) mixed in a large amount, such fuel oil cannot be reused, and it is natural that the fuel oil can be stored in the sludge tank or waste oil tank. In the case of the fuel oil discarded through the fuel oil supply block (2: High Pressure Block) and the fuel oil injection pump (1), it corresponds to the clean fuel oil (D1; D2), considering the reuse thereof. Was not achieved at all, a large amount of fuel oil was being consumed.
또한, 선박용 엔진이나 대형 발전을 위한 대용량의 엔진에 있어서는 엔진을 향해 공급되는 연료유의 공급압력이 상당한 고압을 유지하여야 하는 바, 이러한 고압상태로 이송되는 연료유에 의하여 각종 부품으로부터 누유 또는 배유되는 연료유의 양이 많이 발생하게 되었다.In addition, in a marine engine or a large-capacity engine for large-scale power generation, the supply pressure of the fuel oil supplied toward the engine must be maintained at a high pressure. Therefore, the fuel oil leaked or drained from various parts by the fuel oil conveyed at such a high pressure state must be maintained. A lot of sheep were generated.
따라서 본 발명은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 그 목적은 선박 혹은 육상의 대형 발전설비에 사용되는 중 대형 엔진의 연료유 시스템에 있어서, 엔진내로 공급되어 연소되지 못하고 버려지는 깨끗한 연료유를 모아 재사용(Recycling)할 수 있도록 하는 중 대형 엔진의 연료유 재사용 시스템을 제공함에 있다.Therefore, the present invention is to solve the conventional problems as described above, the object of the fuel oil system of heavy engines used in ships or onshore large-scale power generation facilities, clean fuel that is not supplied and burned into the engine is not burned It is to provide a fuel oil reuse system for a large engine to collect and recycle oil.

It is characterized in that it comprises a separate recirculation fuel flow path to collect the oil to be re-supplied to the settle tank.
상기 주입펌프(Injection Pump)와 공급블록(High Pressure Block)과 연결되는 재순환용 연료유로 상에는 누설되는 연료유가 정상 이상으로 많을 때(비정상 누유) 알람을 줄 수 있는 연료유 누유량 알림 탱크(FO Leakage Alarm Tank)를 포함하여 구성할 수 있다.FO Leakage fuel oil leakage notification tank (FO Leakage) that can give an alarm when the fuel oil leaked on the recirculation fuel flow path connected to the injection pump and the supply block (High Pressure Block) more than normal (abnormal leakage) Alarm Tank) can be configured.
상기와 같은 수단으로부터 본 발명은 기존 연료유 시스템에 있어서 엔진 내부에서 연소되지 못하고 누유 또는 배유되어 오염된 연료유와 함께 슬러지탱크 혹은 폐연료유탱크로 버져지던 배유되어진 깨끗한 연료유를 재순환 유로를 이용하여 재차 세틀탱크로 공급하여 재사용할 수 있도록 함으로서, 엔진의 연료소모를 크게 절감시킬 뿐만 아니라 환경오염 또한 줄일 수 있는 효과가 있는 것이다.From the above means, the present invention provides a recirculation flow path for clean fuel oil that has been dumped into a sludge tank or a spent fuel oil tank together with fuel oil that has not been combusted in an engine or leaked or drained and contaminated in an existing fuel oil system. By using it again to be supplied to the settle tank again, it will not only significantly reduce the fuel consumption of the engine, but also reduce the environmental pollution.
이하, 본 발명의 실시예를 첨부도면과 연계하여 상세히 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 엔진의 연료유 재사용 시스템의 다이어그램을 도시한 것으로, 2 shows a diagram of a fuel oil reuse system of an engine according to the invention,
본 발명은 엔진의 연료유 이송 시스템에 있어서; 세틀탱크(Settling Tank)로부터 이송된 연료유를 엔진의 내부 실린더로 고압의 압력으로 공급하는 주입펌프(1:Injection Pump)와 상기 주입펌프(1)와 엔진실린더를 연결하는 공급블록(2:High Pressure Block)으로부터 배유되는 연료유(D1;D2)를 모아 상기 세틀탱크로 재공급할 수 있도록 별도의 재순환용 연료유로(D10)를 포함하여 구성한다.The present invention provides a fuel oil transfer system of an engine; Injection pump (1: Injection Pump) for supplying the fuel oil transferred from the Settling Tank to the internal cylinder of the engine at a high pressure and a supply block (2: High) connecting the injection pump (1) and the engine cylinder And a separate recirculating fuel flow path D10 to collect the fuel oils D1 and D2 discharged from the pressure block and to resupply the settling tank.
이때, 상기 주입펌프(1:Injection Pump)와 공급블록(2:High Pressure Block)과 연결되는 재순환용 연료유로(D10) 상에는 배유 또는 누유되는 연료유의 양이 정 상적인지 아닌지 확인할 수 있도록 연료유 이송량 알림용 탱크(7:FO Leakage Alarm Tank)를 포함하여 구성할 수 있다.At this time, the amount of fuel oil transported on the recirculation fuel flow path (D10) connected to the injection pump (1: Injection pump) and the supply block (2: High Pressure Block) to check whether the amount of fuel oil drained or leaked is normal or not. It can be configured to include a notification tank (7: FO Leakage Alarm Tank).
상기 연료유 주입펌프(1:Injection Pump)를 통하여 엔진 실린더 내부로 연료유를 공급할 시 엔진에서 필요로 하는 연료유 양과, 엔진의 노즐에서 분사되기 적합한 연료유의 주입압력을 충분히 만족시킬 수 있도록 많은 양의 연료유를 공급하고 누설 또는 배유되는 잔여분의 연료유와, 상기 주입펌프(1)를 통하여 이송되는 연료유가 공급블록(2:High Pressure Block)통하여 엔진 실린더를 향해 이송될 시 누설되는 연료유는 재순환용 연료유로(D10)를 거쳐 세틀탱크(Settling Tank)로 유입된다.When supplying fuel oil into the engine cylinder through the fuel oil injection pump (1: Injection Pump), a large amount to sufficiently satisfy the amount of fuel oil required by the engine, and the injection pressure of the fuel oil suitable for injection from the nozzle of the engine Fuel oil leaked when the fuel oil is supplied and leaked or drained, and the fuel oil leaked when the fuel oil conveyed through the
이때, 상기 연료유로(D10)상에 설치된 이송량 알림용 탱크(7:Leakage Alarm Tank)를 지나는 연료유는 볼 플로우트 센서 방식으로 연료유의 이상 누유 시 알람을 울려 주게 된다.At this time, the fuel oil passing through the transfer amount notification tank (7: Leakage Alarm Tank) installed on the fuel flow path (D10) is a ball float sensor method to alarm the abnormal leakage of fuel oil.
한편, 본 발명에 따른 재순환용 연료유로(D10)를 통하여 세틀탱크를 향해 재순환되는 연료유는 별도의 믹싱탱크(Mixing Tank)를 통하여 연료탱크로부터 세틀탱크로 이송되는 연료유와 섞인 상태로 공급되거나 혹은 별도의 청정기(Purifier)를 통하여 불순물을 재차 필터링한 상태로 세틀탱크에 공급될 수 있다.On the other hand, the fuel oil recycled toward the settling tank through the recirculating fuel flow path (D10) according to the present invention is supplied in a mixed state with the fuel oil transported from the fuel tank to the settling tank through a separate mixing tank or Alternatively, the impurities may be supplied to the settle tank again by filtering impurities through a separate purifier.
이상과 같이, 엔진에 공급되는 연료유의 시스템에 있어서, 기존의 슬러지탱크 혹은 폐연료유탱크로 직접 버려졌던 깨끗한 상태의 연료유를 모아 다시 세틀탱크로 재공급하여 줌으로서 연료유의 절감이 기대될 수 있는 것이며, 특히 본 발명 에 따른 연료유의 재사용 시스템은 선박 및 육상의 대형 발전설비와 추진설비 같은 중 대형 엔진에 있어서 그 절감효율이 더욱 더 기대되는 것이다. As described above, in the fuel oil system supplied to the engine, the fuel oil can be reduced by collecting the clean fuel oil which has been directly discarded into the existing sludge tank or the waste fuel oil tank and re-supplying it to the settling tank again. In particular, the fuel oil reuse system according to the present invention is expected to further reduce the efficiency of medium and large engines, such as large power plants and propulsion plants of ships and land.
한편, 본 발명에 따른 연료유 재사용 시스템을 이용한 실제 엔진 타입별로 연료의 절감되는 양을 확인한 결과 다음과 같은 수준의 연료절감 효율을 획득할 수 있다.On the other hand, as a result of confirming the amount of reduction of fuel for each actual engine type using the fuel oil reuse system according to the present invention, the following level of fuel saving efficiency can be obtained.
- 엔진 타입1(H17/28) : 0.125 l/cyl.hourEngine type 1 (H17 / 28): 0.125 l / cyl.hour
- 엔진 타입2(H21/32) : 0.149 l/cyl.hourEngine type 2 (H21 / 32): 0.149 l / cyl.hour
- 엔진 타입3(H25/33) : 0.197 l/cyl.hourEngine type 3 (H25 / 33): 0.197 l / cyl.hour
- 엔진 타입4(H32/40) : 0.124 l/cyl.hourEngine type 4 (H32 / 40): 0.124 l / cyl.hour
이는 본 출원인이 현대중공업 내 중형엔진 시운전장에서 테스트 한 결과로서 실제 선박이나 육상 발전용 엔진에 적용 시에는 연료유 압력이 시운전장에서보다 더 높기 때문에 더 많은 양의 연료유가 버려지고 있는 것이 보고되고 있으며, 이는 실제 연료유 재사용 시스템 사용 시 테스트 결과 값보다 더욱 많은 연료유가 절감될 것으로 기대된다.This is the result of the applicant's testing in the heavy engine test yard of Hyundai Heavy Industries, and when it is applied to the actual ship or onshore power generation engine, it is reported that the amount of fuel oil is discarded because the fuel oil pressure is higher than that at the test yard. This is expected to save more fuel oil than the test results when using the actual fuel oil reuse system.
본 발명은 상술한 특정의 바람직한 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그 와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
