Description
Technical field
The present invention relates to a kind of according to the fuel facility at least one marine diesel oil internal-combustion engine of the preamble of claim 1.In addition, the present invention relates to a kind of for moving the method for this fuel facility.
Background technique
From practice, known marine diesel oil internal-combustion engine can move by different fuel types.Therefore for example feasible is that marine diesel oil internal-combustion engine moves with astatki on the one hand, and moves with distillate fuel (Destillatkraftstoff) on the other hand.Although astatki cost is favourable, but because its very high sulphur content causes very high fuel draining thing relatively.Distillate fuel and cause lower exhaust emission, however more expensive.On high sea, marine diesel oil internal-combustion engine utilizes astatki to move for cost reason.And if boats and ships should be in so-called SECA (sulphur emissions control zone in inshore, Sulphur Emission Control Areal) move in region, must so change so the operation of marine diesel oil internal-combustion engine for the reason of effulent,, from astatki transforms to and distillates fuel.Only, in the time that marine diesel oil internal-combustion engine meets the emission regulation in SECA region because burning distillates fuel aspect discharge of poisonous waste, boats and ships just can sail in such SECA region at that time.
According to practice, fuel facility (can be marine diesel oil internal-combustion engine or supply astatki by means of it, or supply distillating fuel) for marine diesel oil internal-combustion engine has so-called feeder fuel circulating system (Feeder-Kraftstoffkreislauf) and so-called booster fuel circulating system (Booster-Kraftstoffkreislauf).
By feeder fuel circulating system can be by means of the first pump-unit in the direction of mixing tank or carry the first fuel or carry the second fuel.The second pump-unit by means of the booster circulatory system can be carried taking mixing tank as starting point fuel in the direction of specific or each marine diesel oil internal-combustion engine.The first pump-unit of feeder fuel circulating system aspirates corresponding fuel at this with the first delivered volume stream, wherein, the first sub-delivered volume stream of the first delivered volume stream is carried in the direction of mixing tank, and wherein, the second sub-delivered volume stream of the first delivered volume stream is circulated in feeder fuel circulating system.The second pump-unit of booster fuel circulating system flows (it is obviously greater than the first delivered volume stream) suction of fuel from mixing tank with the second delivered volume.Therefore the more fuel in fact consuming than marine diesel oil internal-combustion engine is carried by specific or each marine diesel oil internal-combustion engine, to therefore the unnecessary fuel that is particularly useful for cooling object and lubricated object is provided.The fuel not consumed by specific or each internal-combustion engine draws and gets back in mixing tank via the backflow portion (R ü cklauf) of booster fuel circulating system.
Due to delivered volume different in feeder fuel circulating system and in booster fuel circulating system, fuel in feeder fuel circulating system being carried be converted on distillating fuel booster fuel circulating system during from astatki, astatki is undertaken relatively very slowly by the replacement distillating fuel.From utilizing the running in the transition process of utilizing the operation that distillates fuel of astatki, taking the feeder circulatory system as starting point, only distillating fuel more than as the astatki consuming in the booster circulatory system is directed in mixing tank.Therefore the dilution that, astatki utilization distillates fuel in booster fuel circulating system is only carried out relatively very slowly.So, in order to meet the emission regulation in SECA region, until in the booster circulatory system astatki distillated fuel with sufficient degree alternative, this cause need relative long time.
Therefore, for known fuel facility from practice, fuel in the feeder circulatory system is carried after astatki is converted to and distillates fuel, this is sustainable up to exceeding 10 hours, until can meet the emission regulation in SECA region due to the sufficient fuel replacement in booster fuel circulating system.
Summary of the invention
With this as the starting point, the object of the present invention is to provide a kind of novel fuel facility at least one marine diesel oil internal-combustion engine and a kind of for moving the method for this fuel facility.This object realizes by fuel facility according to claim 1.According to the present invention, the first pump-unit of feeder fuel circulating system so designs,, this first pump-unit (transforms to the second fuel type from the first fuel type for the operation of specific or each marine diesel oil internal-combustion engine therein) taking the second fuel tank as starting point to be greater than the 3rd delivered volume stream suction the second fuel of the first delivered volume stream in conversion operation pattern.
According to the present invention, the first pump-unit of feeder fuel circulating system so designs, that is, this first pump-unit is from fuel tank suction the 3rd delivered volume stream for the second fuel type in conversion operation pattern, and it is greater than the first delivered volume stream in normal operation mode.Can in booster fuel circulating system, obviously replace quickly the first fuel (especially astatki) by the second fuel (especially by distillating fuel) thus, thereby specific or each marine diesel oil internal-combustion engine can obviously be followed the emission regulation in SECA region quickly, because be feasible according to putting into practice this up to now.Therefore the boats and ships with good grounds fuel facility of the present invention can in beginning in feeder fuel circulating system, from astatki, the fuel to distillating fuel sails in SECA region after changing quickly.
Preferably, the first pump-unit of feeder fuel circulating system so designs,, this first pump-unit in conversion operation pattern with this 3rd delivered volume stream suction the second fuel: the second delivered volume stream corresponding to booster fuel circulating system towards the first sub-delivered volume stream of carrying in the direction of mixing tank of the 3rd delivered volume stream.This allows emission regulation particularly advantageous by the second fuel type in booster fuel circulating system and that replace rapidly the first fuel type and therefore meet SECA region in fuel conveying especially soon after the first fuel type is converted to the second fuel type

Fuel facility 1 comprises feeder fuel circulating system 4 and booster fuel circulating system 5.
Feeder fuel circulating system 4 has the first pump-unit 6, and it is formed by two petrolifts 7 and 8 of parallel connection in shown embodiment.In shown embodiment, before each in two pumps 7 and 8 is correspondingly positioned at stop valve 9 or 10.Should point out that the first pump-unit 6 also can replace two petrolifts 7 and 8 only have a petrolift or have the petrolift in parallel more than two.
By means of the first pump-unit 6 of feeder fuel circulating system 4, depend on the switching position of valve 11, or can the first fuel tank 12 aspirate the first fuel (more particularly for starting point, astatki in shown embodiment), or can the second fuel tank 13 aspirate the second fuel (more particularly for starting point, in shown embodiment, distillate fuel), wherein, can in the direction towards mixing tank 14, carry the fuel aspirating by means of the first pump-unit 6 of feeder fuel circulating system 4.
In the normal operation mode of fuel hauling equipment 1, the corresponding fuel of the first delivered volume stream suction to be limited in from two fuel tanks 12 or 13 one of the first pump-unit 6 of feeder fuel circulating system 4, wherein, can in the direction towards mixing tank 14, carry the first sub-delivered volume stream of the first delivered volume stream, and wherein, the second sub-delivered volume of this first delivered volume stream is flowed through and is circulated in feeder fuel circulating system 4 by circulation loop 15 (pressure limit valve 16 is integrated in this circulation loop).
In the time that marine diesel oil internal-combustion engine 2 and 3 amounts to 100% fuel with full load operation, consumption, by pump-unit 6, in from two fuel tanks 12 or 13, the first delivered volume stream of suction typically is 160% of this fuel consumption at that time, wherein, so be 100% towards the first sub-delivered volume stream of carrying in the direction of mixing tank 14, so and guiding is 60% by the second sub-delivered volume stream of circulation loop 15.
According to Fig. 1, first pump-unit 6 via feeder fuel circulating system 4 of the first delivered volume stream can be conducted through flow measuring device 17-that is in the time being placed in flow measuring device 17 valve 18 before and opening towards the first sub-delivered volume stream of carrying in the direction of mixing tank 14.
Alternatively, for example, in the time of flow measuring device 17 defectiveness, can the first sub-delivered volume stream guiding of the first delivered volume stream be walked around to flow measuring device 17 via bypass line 19 at that time, wherein, valve 18 valve 20 closed and that be integrated in bypass line 19 is opened at that time.
In this, the the second sub-delivered volume stream (it circulates in feeder fuel circulating system 4 via circulation loop 15) that should point out the first delivered volume stream so regulates by means of pressure limit valve 16,, form constant pressure level for the first sub-delivered volume stream that is delivered to mixing tank 14.This pressure level for example can be 7bar.
When via feeder fuel circulating system 4 using the first fuel tank 12 as starting point as the first fuel type by astatki when carrying in the direction of mixing tank 14, this astatki of preheating in the first fuel tank 12 at that time, wherein, the temperature of astatki in the first sub-delivered volume stream being delivered in mixing tank 14 typically is approximately 90 ° of C.
The booster circulatory system 5 has the second pump-unit 21, by means of its can be from mixing tank 14 suction of fuel and fuel can being carried towards the direction of specific or each marine diesel oil internal-combustion engine 2,3.These parts of booster fuel circulating system 5 (can mixing tank 14 being that the fuel of naming a person for a particular job is transported on specific or each marine diesel oil internal-combustion engine 2,3 via it) are also called as the beginning stream portion 22 of booster fuel circulating system 5.By the beginning stream portion 22 towards carry on specific or each marine diesel oil internal-combustion engine 2,3 but in specific or each marine diesel oil internal-combustion engine 2,3 fuel of burning can in the direction of mixing tank 14, draw back by the backflow portion 23 of booster fuel circulating system 5.
As can be from learning Fig. 1, the fuel aspirating from mixing tank 14 by the second pump-unit 21 of booster fuel circulating system 5 can be carried by Preheating unit 24, more particularly, in the time that moving with astatki, specific or each marine diesel oil internal-combustion engine 2,3 carries out preheating.In the time that specific or each marine diesel oil internal-combustion engine 2,3 moves to distillate fuel, be placed in Preheating unit 24 valve 25 closures before, to guide and distillate fuel in the situation that valve 27 is opened by bypass line 26 at that time.The beginning that device for measuring viscosity 28 is integrated into booster fuel circulating system 5 in Preheating unit 24 downstreams is in stream portion 22, in the time that astatki is guided through to Preheating unit 24, this device for measuring viscosity 28 is adjusted the operation of Preheating unit 24, to affect the viscosity of astatki by Preheating unit 24.
Typically, astatki is heated by Preheating unit 24, to set the viscosity of 12-14 c St (Stokes, Stokes), wherein, in booster fuel circulating system 5, for example can be 12bar at the pressure level in the second pump-unit 21 downstreams.
As already implemented, the second pump-unit 21 of booster fuel circulating system 5 suction of fuel and the direction towards specific or each marine diesel oil internal-combustion engine 2,3 from mixing tank 14 are carried this fuel-more particularly, and this depends on the open position that is placed in the valve 29,30 before marine diesel oil internal-combustion engine 2,3.The second pump-unit 21 of booster fuel circulating system 5 flows (it is apparently higher than first delivered volume stream of feeder fuel circulating system 4) suction of fuel with the second delivered volume from mixing tank 14.
Therefore in a specific embodiment, be arranged to: in the time that the first delivered volume stream of feeder fuel circulating system 4 is 160%, the second delivered volume stream of booster fuel circulating system 5 is 300% at that time, wherein, in the time that two valves 29,30 are opened, the corresponding sub-delivered volume stream by 150% is guided through each marine diesel oil internal-combustion engine 2,3 at that time.
Maximum 100% fuel but two marine diesel oil internal-combustion engines 2,3 can burn together under full load, for maximum 50% fuel of independent each marine diesel oil internal-combustion engine 2,3 corresponding burning.Therefore by than carrying by two marine diesel oil internal-combustion engines 2,3 at the more fuel of marine diesel oil combustion in IC engine, wherein, unnecessary fuel is for Cooling and Lubricator and can in the direction of mixing tank 14, draw back by backflow portion 23.
When one in two valves 29,30 when closed, in the time that one in two marine diesel oil internal-combustion engines 2, the 3 beginning stream portion 22 from booster fuel circulating system 5 departs from, can not carry at that time such fuel of the marine diesel oil internal-combustion engine 2,3 by departing from can walk around via bypass line 31 guiding other marine diesel oil internal-combustion engine 3,2, wherein, the bypass valve 32 being integrated at that time in this bypass line 31 is opened.
Can be depending on the position of the valve 33 being integrated in backflow portion 23 or be conducted through cooling unit 34 towards the fuel drawing back in the direction of mixing tank 14 via the backflow portion 23 of booster fuel circulating system 5, or be conducted through bypass line 35.
When astatki is in specific or each marine diesel oil internal-combustion engine 2,3 during as fuel combustion, unburned unnecessary astatki is walked around cooling unit 34 via bypass line 35 guiding at that time.In the time distillating fuel in specific or each marine diesel oil internal-combustion engine 2,3 as fuel combustion, unburned unnecessary distillating fuel can be depended on to its temperature is guided through cooling unit 34 at that time.
According to Fig. 1; in shown embodiment; strainer 36,37 is at corresponding valve 29; before 30 downstreams are placed in each internal-combustion engine 2,3, to thick pollutant is leached from be delivered to the fuel booster fuel circulating system 5 and therefore protect specific or each marine diesel oil internal-combustion engine 2,3 to be without prejudice.
In present meaning of the present invention herein, propose: the first pump-unit 6 that so designs feeder fuel circulating system 4,, its in conversion operation pattern-therein for the specific or each marine diesel oil internal-combustion engine 2,3 of operation from the first fuel (being astatki) transform to the second fuel (distillating fuel)-no longer aspirate the second fuel with the first delivered volume stream taking the second fuel tank 13 for starting point, but aspirate the second fuel to be greater than the 3rd delivered volume stream that the first delivered volume flows.
A favourable design proposal according to the present invention is arranged to: the first pump-unit 6 of feeder fuel circulating system 4 so designs, that is, it aspirates the second fuel with this 3rd delivered volume stream in conversion operation pattern from the second fuel tank 13; The first sub-delivered volume stream towards carrying in the direction of mixing tank 14 of the 3rd delivered volume stream is compared larger or equates with the second delivered volume stream (, the delivered volume of the second pump-unit 21 of booster fuel circulating system stream) of booster fuel circulating system 5.
In a specific embodiment, be arranged to: first of the 3rd delivered volume stream the sub-delivered volume stream in conversion operation pattern (its pump-unit 6 taking feeder fuel circulating system 4 carry in the direction of mixing tank 14 for starting point), as 300%, flows corresponding to the second delivered volume of booster fuel circulating system 5.
Can be arranged to via each corresponding 160% the second fuel that aspirates from the second fuel tank 13 in two pumps 7,8 of the pump-unit 6 of feeder fuel circulating system 4 at this, to guide mixing tank 14 into and make remaining 20% to circulate in feeder fuel circulating system 4 by circulation loop 15 300%.
In the backflow portion 23 of booster fuel circulating system 5, be connected with the first stop valve 38 in mixing tank 14 upstreams, it opens in normal operation mode, and closed in conversion operation pattern.Separate fuel in the first stop valve 38 upstreams from the backflow portion 23 of booster fuel circulating system 5 and draw pipeline 39, it leads to the first fuel tank 12 for astatki in shown embodiment.The second stop valve 40 is connected to this fuel and draws in pipeline 39, and this second stop valve 40 is closed in normal operation mode, and opens in conversion operation pattern.
Therefore by means of the present invention can fuel supply is transformed into from astatki distillate fuel time improve the transmission power of the first pump-unit 6 of feeder fuel circulating system 4, to remove fast thus the astatki that is also present in booster fuel circulating system 5 and by the fast replacing astatki that distillates fuel from booster fuel circulating system.For this reason, after the transmission power of the first pump-unit 6 that improves feeder fuel circulating system 4, first open the second stop valve 40 and closed the first stop valve 38 then.
Preferably, after transforming in conversion operation pattern, move the first pump-unit 6 of feeder fuel circulating system 4 with the transmission power improving for the volume flow of the time period limiting or restriction, thereby therefore for the time period limiting or for the volume flow limiting, conversion operation pattern is kept activating.
After this time period of process or after reaching this volume flow, change back in normal operation mode, wherein, first this manipulated to two stop valves 38 and 40, open the first stop valve 38 and closed the second stop valve 40, to and then reduce the transmission power of the first pump-unit 6 of feeder fuel circulating system 4, be reduced to the first delivered volume stream from the 3rd delivered volume stream, in normal operation mode, from corresponding fuel tank 12,13, aspirate this first delivered volume by the first pump-unit 6 and flow.
Therefore can distillate fuel at once will being present in that astatki booster fuel circulating system 5 is removed rapidly from this booster fuel circulating system 5 and replacing by distillating fuel rapidly transforming to from astatki supply by means of the present invention, thereby boats and ships can sail in SECA region in a short period of time after fuel supply being transformed in the supply that distillates fuel.
According to a favourable improvement project of the present invention, be parallel to the second stop valve 40 and be connected with modulating valve 41.The measurement signal that this modulating valve 41 can be depending on flow measuring device 17 manipulates.When specific or each marine diesel oil internal-combustion engine 2, the 3 relatively little fuel of burning and therefore by feeder fuel circulating system 4 by relatively little fuel supplement in mixing tank 14 time, the direction that can utilize at that time this modulating valve 41 by correspondingly opening this modulating valve 41, fuel to be drawn to pipeline 39 from backflow portion 23 towards fuel is drawn, to therefore do not depend on specific or each marine diesel oil internal-combustion engine 2 in booster fuel circulating system 5, 3 actual fuel consumption is set in the constant consumption in booster fuel circulating system 5, to therefore constant fuel quantity is added in mixing tank 14 by feeder fuel circulating system 4.
If should be reduced in the temperature in the booster fuel circulating system 5 of fuel facility 1 during transforming to conversion operation pattern from normal operation mode time before the transmission power of the first pump-unit 6 that improves feeder fuel circulating system 4, this is especially favourable so.
As set forth above, at astatki run duration, the temperature levels in booster fuel circulating system 5 is about 140 ° of C.But the temperature levels in booster fuel circulating system 5 should be dropped to approximately 45 ° of C before transforming in the operation that distillates fuel.
According to practice, depend on the actual fuel consumption of specific or each marine diesel oil internal-combustion engine 2,3 for the needed endurance of such cooling procedure.Can not depend on that by the measurement signal manipulation modulating valve 41 that depends on flow measuring device 17 actual consumption of specific or each marine diesel oil internal-combustion engine 2,3 designs cooling procedure.Therefore can be switched to therein the actual consumption that the time point distillating fuel in operation does not depend on specific or each marine diesel oil internal-combustion engine 2,3 yet.
Can simulate the constant high fuel consumption of specific or each marine diesel oil internal-combustion engine 2,3 by opening modulating valve 41, to constant delivered volume is transported in mixing tank 14 via pump-unit 6.Therefore, in the time that the measurement signal of flow measuring device 17 demonstrates the relative very little consumption of specific or each marine diesel oil internal-combustion engine 2,3, further open at that time modulating valve 41, and in the time that the measurement signal of flow measuring device 17 demonstrates the relative very high consumption of specific or each marine diesel oil internal-combustion engine 2,3, be further closed at that time modulating valve 41.
Preferably, depend on that the measurement signal of flow measuring device 17 so carries out the manipulation of modulating valve 41, that is, relatively measurement signal and the theoretical value of flow measuring device 17.If the measurement signal of flow measuring device 17 is greater than theoretical value or corresponding to this theoretical value, the actual consumption of so specific or each marine diesel oil internal-combustion engine 2,3 is corresponding very high, make so modulating valve 41 closures.If instead the measurement signal of flow measuring device 17 is less than theoretical value, the actual consumption of so specific or each marine diesel oil internal-combustion engine 2,3 is lower, depend on that so the deviation between theoretical value and the actual value of measurement signal opens modulating valve 41, so that the consumption of analog constant and constant volume of fuel stream being transported in mixing tank 14 by feeder fuel circulating system 4.This causes and does not depend on the temperature levels of load ground fast reducing in booster fuel circulating system 5.
