Description

8200783-2 10 15 20 25 30 35 2 och att åstadkuuna ett bränslesystem i vilket praktiskt taget alla bränn- bara fraktioner i bränslet tillvaratagespl vi lket matar_ och inspruf, ningspumpar arbetar utan störningar och utan att förslitas, och i vilket blandningskärlet kan placeras relativt lågt i fartyget samtidigt som dess dimensioner kan hållas små. 8200783-2 10 15 20 25 30 35 2 and to provide a fuel system in which practically all combustible fractions in the fuel are recovered during feeding and testing, pumps operate without disturbances and without wear, and in which the mixing vessel can be placed relatively low. in the ship while keeping its dimensions small.

Detta ändamål uppfylles genom att uppfinningen erhål- lit de i patentkraven angivna kännetecknen.This object is fulfilled by the invention obtaining the features stated in the claims.

Figurbeskrivning Figuren åskådliggör schematiskt ett bränslesystem en- ligt uppfinningen.Description of the figure The figure schematically illustrates a fuel system according to the invention.

Föredraqen utförindsform En tank 1 innehållande brännolja bestående av en bland- ning av såväl lättare som tyngre fraktioner är installerad i ett fartyg, vars dieselmotor 2 drivs av den nämnda brännoljan efter att den upphettats. Den ca 80°:iga oljan ledes under självtryck till en pumpanordning med två pumpar 3 och 4, varav den ena (4) är en reservpump, som inkopplas i det fall den andra fallerar. Pumpen 3, vars kapacitet flerfaldigt översti- ger motorns 2 maximala oljekonsumtion, matar oljan under tryck via en flödesmätare 5 till en hermetisk tillsluten trycktank 6 där den blandas med olja, som icke förbrukats av motorn och därför genom en returledning 7 matats från motorn till trycktanken.Preferred embodiment A tank 1 containing fuel oil consisting of a mixture of both lighter and heavier fractions is installed in a vessel, the diesel engine 2 of which is driven by the said fuel oil after it has been heated. The approximately 80 ° oil is led under self-pressure to a pump device with two pumps 3 and 4, one of which (4) is a spare pump, which is switched on in the event that the other fails. The pump 3, whose capacity several times exceeds the maximum oil consumption of the engine 2, feeds the oil under pressure via a flow meter 5 to a hermetically sealed pressure tank 6 where it is mixed with oil which is not consumed by the engine and therefore fed from the engine to the pressure tank .

Beroende på att oljan innehåller komponenter som för- gasas vid den temperatur (ca l30°C) som råder i trycktanken 6 ansamlas gaser i trycktankens övre del. Beroende på att tryck- et i trycktanken hålles relativt högt och överstiger ångbild- ningstrycket i den tryckkrets som innehåller trycktanken, motorn 2 och en nedan beskriven matarpunpanordning förgasas emellertid en- dast en liten Känd av dessa fraktioner medan den resterande mängden kvar- blíf i VätSKGfOITH löstiden av tyngre kolväten bestående oljan i trycktanken. När mängden gas i trycktanken 6 har ökat så att oljan i densamma befinner sig under en förutbestämd nivå på- verkas en niváavkännare 8, som därvid öppnar en ventil 9 i en ledning 10 mellan trycktanken 6 och tanken l, så att gaser- na inuti trycktanken utan att förorena omgivningen ledes tillbaka till tanken l. lO l5 20 25 30 35 8200783-2 3 Övertrycket i trycktanken 6 hålles i huvudsak konstant medelst en automatiskt verkande tryckregleringsventil ll, som är inkopplad över pumparna 3 och 4. Till trycktanken matas exakt den mängd olja som motsvarar den aktuella konsum- tionen i motorn 2, trots att pumpen 3 har en kapacitet som är väsentligt större. Den olja som icke matas in i trycktanken kommer därför att återföras till pumpens 3 sugsida via venti- len ll och flera gånger àtercirkuleras genom pumpen.Due to the fact that the oil contains components that are gasified at the temperature (approx. 130 ° C) prevailing in the pressure tank 6, gases accumulate in the upper part of the pressure tank. However, due to the fact that the pressure in the pressure tank is kept relatively high and exceeds the vapor pressure in the pressure circuit containing the pressure tank, the engine 2 and a feed point device described below, only a small amount of these fractions is gasified while the remaining amount remains in VätSKGfOITH the dissolution time of heavier hydrocarbons consisting of the oil in the pressure tank. When the amount of gas in the pressure tank 6 has increased so that the oil therein is below a predetermined level, a level sensor 8 is actuated, which thereby opens a valve 9 in a line 10 between the pressure tank 6 and the tank 1, so that the gases inside the pressure tank without polluting the environment, it is led back to the tank l. oil that corresponds to the current consumption in the engine 2, despite the fact that the pump 3 has a capacity that is significantly larger. The oil that is not fed into the pressure tank will therefore be returned to the suction side of the pump 3 via the valve 11 and recirculated several times through the pump.

För att en fullgod blandning av den från trycktanken 6 utmatade oljan skall erhållas och gaserna i denna skall förbli i vätskeform har en statisk blandare 12 anslutits till trycktankens 6 utlopp.In order to obtain a complete mixture of the oil discharged from the pressure tank 6 and the gases in it to remain in liquid form, a static mixer 12 has been connected to the outlet of the pressure tank 6.

Sugsidan på en av två matarpumpar 14 och l5 bestående pumpanordning (varav den ena 15 är en reservpump) är kopplad till blandarens l2 utlopp, Och pumpanordningens trycksida är via en upphettningsanordning 16 och en viskosimeter 17 kopp- lad till motorns 2 insprutningsanordning l8. Varje matarpumps 14, 15 kapacitet överstiger oljeförbrukningen i motorn 2 (och är ca 3 gånger större än denna), vilket innebär att en relativt stor mängd i motorn icke förbrukad olja áterföres till trycktanken 6 via ledningen 7. I anordningen 16 upp- hettas oljan till ca l50°C, vilken temperatur den maximalt har då den införes i motorn.The suction side of a pump device consisting of two feed pumps 14 and 15 (one of which is a spare pump) is connected to the outlet of the mixer 12, and the pressure side of the pump device is connected via a heating device 16 and a viscometer 17 to the injection device 14 of the motor 2. The capacity of each feed pump 14, 15 exceeds the oil consumption in the engine 2 (and is about 3 times greater than this), which means that a relatively large amount of unused oil in the engine is returned to the pressure tank 6 via the line 7. In the device 16 the oil is heated to about 150 ° C, the maximum temperature it has when it is introduced into the engine.

Om båda pumparna 3 och 4 skulle fallera kan en ventil 13, inkopplad i en ledning mellan pumparnas sugsida och mäta- rens 5 utlopp, och ventilen 9 manuellt öppnas, varigenom matarpumpen 14 (eller 15) kan suga olja från trycktanken, som genom självtryck tillföres olja direkt från den relativt högre i fartyget belägna tanken l och som beroende på den öppna ventilen 9 är utsatt för atmosfärtryck.Should both pumps 3 and 4 fail, a valve 13, connected in a line between the suction side of the pumps and the outlet of the meter 5, and the valve 9 can be opened manually, whereby the feed pump 14 (or 15) can suck oil from the pressure tank, which is supplied by self-pressure. oil directly from the relatively higher tank 1 located in the ship and which, depending on the open valve 9, is exposed to atmospheric pressure.

Detaljerna 3 - 6, 8, 9, ll - 13 med tillhörande led- ningar kan lämpligen sammanföras med en styr- och kontroll- panel (icke visad) och inkopplas som en utbytbar enhet (modul) 19 mellan tanken l, motorn 2 och en av detaljerna 14 - 16 bestående, separat enhet (modul) 20. Även om endast en utföringsform av uppfinningen be- skrivits ovan och visats på ritningen torde förstås att upp- finningen icke är begränsad till denna utföringsform utan begränsas endast av det i patentkraven angivna.Details 3 - 6, 8, 9, ll - 13 with associated lines can be conveniently connected to a control and monitoring panel (not shown) and connected as a replaceable unit (module) 19 between the tank 1, the motor 2 and a of the parts 14 - 16 consisting of a separate unit (module) 20. Although only one embodiment of the invention is described above and shown in the drawing, it should be understood that the invention is not limited to this embodiment but is limited only by what is stated in the claims.
