Description
Technical field
The utility model is related to the evaporation vapour of liquid gas vaporization generation（BOG）Utilization technology field, specifically
A kind of BOG is used as the air supply system that dual fuel engine peculiar to vessel supplements fuel.
Background technology
Liquefied natural gas（LNG）As one kind cleaning, efficient gaseous fuel, because it is in ambient influnence, energy efficiency
In terms of distinguishing feature, it has also become the important energy source of 21 development of world economy.The power of main fuel is thus used as using LNG
Ship and using its as filling object gas station also emerge therewith.
LNG for a long time, during massive store, because LNG temperature is far below environment temperature, although to storage tank and
Pipeline takes high performance insulation, but evaporation can not be avoided definitely, and storage tank leaks heat, the gas in tank car with pipeline, added
Heat that defeated interior immersed pump work is produced outside return-air, LNG in note steel cylinder etc. can all produce BOG gases.BOG gases cause system
Pressure increase, final this part BOG gases must not cause energy waste without diffusing；Remain in for a long time in pipeline
Low-temperature liquid gas can also reduce the service life of pipeline.
Utility model content
The purpose of this utility model be to provide it is a kind of by BOG using, LNG steam line liquefied gas is reclaimed
Processing avoids energy waste and reduction fuel consumption from improving energy utilization rate, and residual air processing, environmental protection are carried out to waste gas peculiar to vessel and is vented
A kind of BOG be used as dual fuel engine peculiar to vessel supplement fuel air supply system.
In order to solve the above problems, it is used as dual fuel engine peculiar to vessel the utility model proposes a kind of BOG and supplements fuel
Air supply system, including LNG air supply systems, BOG storage tanks, dual fuel engine, air compressor and baric systerm, the LNG are supplied
Gas system includes LNG storage tank and LNG steam lines, and the LNG storage tank connects the BOG storage tanks, and the LNG steam lines pass through
Connect vaporizer and connect the BOG storage tanks, the BOG storage tanks connect the dual fuel engine by connecting booster, described
Dual fuel engine connects the baric systerm by connecting the air compressor.
Further, the air compressor is provided with anemometer.
Further, the air compressor connects the baric systerm by connecting filter.
