Description
技术领域technical field
本实用新型涉及的是一种船舶柴油机，具体地说是船舶柴油机的供油系统。The utility model relates to a marine diesel engine, in particular to an oil supply system of the marine diesel engine.
背景技术Background technique
按照欧盟法令2005/33/EC-关于修改停靠欧盟港船舶的燃油含流量控制通知，从2010年1月1日起，除了那些外延区域，所有在欧盟港口停靠的船舶，其燃油含硫量不得超过0.10％(重量比)的最高限制。与此同时，美国加利福尼亚空气资源委员会(CARB)也对燃油含硫量的最高限制的生效日做了规定，自2009年7月1日起，所有停靠美国加州港口的船舶使用含硫量不超过1.5％的燃油或0.5的柴油；自2012年1月1日起，所有停靠美国加州港口的船舶使用含硫量不超过0.1％的燃油或柴油；2013年9月12日国务院颁布了《大气污染防治行动计划》，制定了我国空气污染控制的路线图，重点关注三个关键地区：京津冀、长三角和珠三角地区。目前，我国正在制定针对船舶柴油机的国家环境保护标准《船舶发动机排气污染物排放限值和测量方法》，计划于2016年1月正式实施；现已出台《船舶与港口污染防治专项行动实施方案(2015～2020年)》，以求减少船舶尾气二氧化硫、氮氧化物和颗粒物等的排放量。由于上述燃油含硫量限制要求的生效，所有停靠欧盟、加州港口和中国的现有船或新造船都面临主辅机及锅炉低硫燃油转换改造的需要。In accordance with EU Directive 2005/33/EC-Notice on Amending the Control of Fuel Oil Flow Control for Ships Calling at EU Ports, from January 1, 2010, except for those extended areas, all ships calling at EU ports shall not have sulfur content in their fuel oil. Exceeds the maximum limit of 0.10% (by weight). At the same time, the California Air Resources Board (CARB) also stipulated the effective date of the maximum limit on the sulfur content of fuel oil. Since July 1, 2009, all ships calling at California ports in the United States will use sulfur content not exceeding 1.5% fuel oil or 0.5% diesel oil; since January 1, 2012, all ships calling at California ports in the United States will use fuel oil or diesel fuel with a sulfur content of no more than 0.1%; Action Plan for Prevention and Control, which formulated a roadmap for my country's air pollution control, focusing on three key areas: the Beijing-Tianjin-Hebei region, the Yangtze River Delta region, and the Pearl River Delta region. At present, my country is formulating the national environmental protection standard "Limits and Measurement Methods of Exhaust Pollutants from Ship Engines" for marine diesel engines, which is planned to be officially implemented in January 2016; the "Special Action Plan for Ship and Port Pollution Prevention and Control" has been issued (2015-2020)", in order to reduce the emissions of sulfur dioxide, nitrogen oxides and particulate matter from ship exhaust. Due to the entry into force of the above fuel oil sulfur limit requirements, all existing ships or newbuildings calling at ports in the European Union, California and China will face the need to switch to low-sulfur fuel oil for main and auxiliary engines and boilers.
目前针对船用柴油机燃油系统高硫油和低硫油切换的油路设计的方案很少，大多是针对单独一种燃油的油路设计，例如：At present, there are few oil circuit designs for switching between high-sulfur oil and low-sulfur oil in marine diesel engine fuel systems, and most of them are oil circuit designs for a single fuel, such as:
专利CN201410112703.3公开了一种船用高硫燃油净化加热系统，该系统包含：高硫油热油循环加热系统及管路连接该高硫油热油循环加热系统的高硫油净化系统；高硫油热油循环加热系统中循环流通导热油，该高硫油热油循环加热系统包含形成环路的锅炉、高硫油沉淀柜、高硫油日用柜、油气分离器、热油循环泵；高硫油净化系统包含管路连接高硫油沉淀柜的分油机加热器、输入端连接分油机加热器的分油机；分油机输出端管路连接至高硫油日用柜。该专利能够通过加热高硫油，提高高硫油流动性，但是Tier III公布后，在ECAs运行的船舶SOx排放受到了限制，因此该专利应用范围受到了限制。Patent CN201410112703.3 discloses a marine high-sulfur fuel oil purification heating system, which includes: a high-sulfur oil thermal oil circulation heating system and a high-sulfur oil purification system connected to the high-sulfur oil thermal oil circulation heating system by pipelines; Heat transfer oil is circulated in the oil hot oil circulation heating system.

This patent can improve the fluidity of high-sulfur oil by heating high-sulfur oil, but after the publication of Tier III, the SOx emission of ships operating in ECAs is restricted, so the scope of application of this patent is limited.
专利“一种带溢流阀的高硫油共轨系统”，该系统包含：低硫油日用油箱、高硫油日用油箱、低/高硫油切换阀、高压油泵、共轨管、轨压传感器、喷油器、溢流阀和电子控制单元。其中溢流阀集成了安全阀和冲洗阀的功能，可同时满足高硫油共轨系统超压保护、低/高硫油切换冲洗、紧急停车三项功能需求。该专利虽然设计了低/高硫油切换，但是忽略了不同燃油的粘性和润滑性的不同。Patent "a high-sulfur oil common rail system with relief valve", the system includes: low-sulfur oil daily fuel tank, high-sulfur oil daily fuel tank, low/high-sulfur oil switching valve, high-pressure oil pump, common rail pipe, Rail pressure sensors, fuel injectors, relief valves and electronic control units. Among them, the relief valve integrates the functions of safety valve and flushing valve, which can simultaneously meet the three functional requirements of overpressure protection of high-sulfur oil common rail system, low/high-sulfur oil switching flushing, and emergency shutdown. Although this patent designs low/high-sulfur oil switching, it ignores the differences in viscosity and lubricity of different fuels.

下面结合附图举例对本实用新型做更详细地描述：The utility model is described in more detail below in conjunction with accompanying drawing example:
结合图1～2，本实用新型一种船舶柴油机双燃料供油系统包括主发动机1、供油单元2、高硫油舱3和低硫油舱4；所述的主发动机1通过油路与供油单元2相连；所述的高硫油舱3和低硫油舱4通过油路与供油单元2相连。所述的供油单元2包括：燃油输送泵5、燃油循环泵6、燃油加热器7、低硫油冷却器8、全流式滤清器9、燃油回流筒10、自动除气阀11和供油三通阀12。所述的燃油输送泵5一端与高硫油箱3、低硫油箱4分别相连，另一端与燃油回流筒10相连；所述的燃油回流筒10设有油路直接与高硫油舱3相连；所述的燃油回流筒10设有回路与主发动机1相连；所述的燃油回流筒10设有回路依次与燃油循环泵6、燃油加热器7和全流式滤清器9相连；所述的燃油加热器7与全流式滤清器9之间连接有低硫油冷却器8。1-2, a dual-fuel oil supply system for marine diesel engines of the present invention includes a main engine 1, an oil supply unit 2, a high-sulfur oil tank 3 and a low-sulfur oil tank 4; The oil supply unit 2 is connected; the high-sulfur oil tank 3 and the low-sulfur oil tank 4 are connected to the oil supply unit 2 through an oil circuit. The fuel supply unit 2 includes: a fuel delivery pump 5, a fuel circulation pump 6, a fuel heater 7, a low-sulfur oil cooler 8, a full-flow filter 9, a fuel return cylinder 10, an automatic degassing valve 11 and Oil supply three-way valve 12. One end of the fuel delivery pump 5 is connected to the high-sulfur fuel tank 3 and the low-sulfur fuel tank 4 respectively, and the other end is connected to the fuel oil return cylinder 10; the fuel oil return cylinder 10 is provided with an oil circuit directly connected to the high-sulfur fuel tank 3; The fuel return cylinder 10 is provided with a circuit connected to the main engine 1; the fuel return cylinder 10 is provided with a circuit connected with the fuel circulation pump 6, the fuel heater 7 and the full-flow filter 9 in sequence; A low-sulfur oil cooler 8 is connected between the fuel heater 7 and the full-flow filter 9 .
由于低硫油的价格比较高，为了减少低硫油消耗，现在最普遍的方法是：船舶在ECAs外运行时燃用高硫油，在进入ECAs时燃用低硫油，因此，本专利对船舶柴油机燃油系统进行创新：分别设立低硫油舱和高硫油舱，且高硫油舱加热保温(一般保持在80℃左右)；而低硫油粘度较低，会对喷油嘴造成磨损，需要冷却以加大粘性，因此在油舱布置时应避免低硫油舱与高硫油舱表面直接相连；另外，为了增大低硫油的粘度，保证喷油嘴的润滑性，在柴油机主供油管上加装了低硫油冷却器。Due to the relatively high price of low-sulfur oil, in order to reduce the consumption of low-sulfur oil, the most common method is: the ship burns high-sulfur oil when it is running outside ECAs, and burns low-sulfur oil when entering ECAs. Therefore, this patent applies to The fuel system of marine diesel engines is innovated: low-sulfur oil tanks and high-sulfur oil tanks are set up separately, and the high-sulfur oil tanks are heated and kept warm (generally kept at about 80°C); while low-sulfur oil has a low viscosity, which will cause wear to the fuel injectors , it needs to be cooled to increase the viscosity, so the direct connection between the low-sulfur oil tank and the high-sulfur oil tank surface should be avoided when the oil tank is arranged; in addition, in order to increase the viscosity of the low-sulfur oil and ensure the lubricity of the injector nozzle, in the diesel engine A low-sulfur oil cooler is installed on the main oil supply pipe.
