Embodiment
The present invention is illustrated with reference to the drawings and specific embodiments；China's inland river LNG powered ships are generally two-shipper, therefore
The present invention illustrates implementation and the course of work of fuel feed system by taking two-shipper as an example：
As shown in figure 1, a kind of fuel feed system suitable for LNG powered ship gas engines, described fuel gas supply system
System is with least two that one engine of correspondence the is set supply air lines being arranged in parallel；The engine 12 passes through manual shutoff
Valve II 11, spark arrester 10 are connected with the supply air line described in every respectively；Supply air line described in every has what is be linked in sequence
LNG air accumulators 1, hand stop valve I 2, main gas fuel valve I 3, gasification installation 4, filter 5 and pressure-reducing valve 6；Described in every
The engine described in every is also corresponded on supply air line and is provided with main gas fuel valve II 8；Each described main gaseous fuel
One end of valve II 8 is connected with pressure-reducing valve 6, and the other end passes through hand stop valve II 11, spark arrester 10 and corresponding hair respectively
Motivation 12 is connected, and constitutes the shared structure of many engines of a supply air line；In the embodiment, main gas fuel valve, manually cut
Only valve, gasification installation, spark arrester are structure ripe in the prior art, do not do excessive explanation herein；Main gas fuel valve is
Electronic control, can be carried out actively and be automatically controlled by bridge, PLC etc.；LNG air accumulators 1 are used to store LNG fuel；Hand
Dynamic stop valve I 2, hand stop valve II 11 are used for fuel shutoff after main gas fuel valve failure and supplied；Gasification installation 4 is used for will
LNG fuel gasifications are into the gaseous fuel for being available for engine to use；Spark arrester 10 is used to prevent the tempering from engine to combustion gas
Make a very bad impression.
The upper end of each main gas fuel valve II 8 is parallel with the main gas fuel valve III 7 with atmosphere, main gas
Fuel valve III 7 when supply air line is leaked to open；Lower end is parallel with the main gas fuel valve IV 9 with atmosphere,
Main gas fuel valve IV 9 in engine cut-off to open.
Some pressure sensors to judge gas leakage are disposed with described supply air line, it is possible to use parts
The anomalous variation of front and rear pressure difference judges whether to there occurs gas leakage.
LNG air accumulators 1 on one of supply air line connect hand stop valve I 2 and main gas fuel valve I 3, because
Prevent that hand stop valve 2 can cut off combustion gas during main I 3 failure of gas fuel valve；Main gas fuel valve I 3 is followed by gasification installation 4,
Because there is impurity in gas, it is therefore desirable to filtered using filter 5；Gaseous-pressure after filtering should use pressure-reducing valve 6 to adjust
It is whole to arrive required pressure, it is referred to as high-pressure gas more than 10bar, is low-pressure fuel gas less than 10bar；After pressure-reducing valve 6, combustion gas
Pipeline is divided into two-way, is connected to two engines by main gas fuel valve II 8, spark arrester 10, hand stop valve II 11 respectively
12；
LNG air accumulators 1 on another supply air line connect hand stop valve I 2 and main gas fuel valve I 3, because preventing master
Hand stop valve 2 can cut off combustion gas during I 3 failure of gas fuel valve；Main gas fuel valve I 3 is followed by gasification installation 4, because gas
There is impurity in body, it is therefore desirable to filtered using filter 5；Gaseous-pressure after filtering should use pressure-reducing valve 6 to be adjusted to institute
The pressure needed, is referred to as high-pressure gas more than 10bar, is low-pressure fuel gas less than 10bar；After pressure-reducing valve 6, fuel gas pipeline point
For two-way, two engines 12 are connected to by main gas fuel valve II 8, spark arrester 10, hand stop valve II 11 respectively.
In order to ensure the safe and reliable of supply, supply air line should have failure to empty and shut down air emptying function, two kinds of emptyings
Function is not interfere with each other, and is mainly used in the gas being present in pipeline still gasified by engine combustion acting is had neither part nor lot in
Body is discharged, and is particularly prevented these gases from leaking in cabin, is caused danger；The present invention realizes failure by following arrangement
Emptying and shutdown air emptying function：The upper end of main gas fuel valve II 8 is parallel with the main gas fuel valve III 7 with atmosphere, under
End is parallel with the main gas fuel valve IV 9 with atmosphere；Described main gas fuel valve IV 9 is automatic vent valve, for stopping
Breathed freely automatically during car.
The use state of the present invention is as follows：
Hand stop valve I 2, hand stop valve II 11, main gas fuel valve I 3 on one supply air line are opened, and correspondence every
When the main gas fuel valve II 8 that engine is set also is opened, a supply air line is respectively two engine supply；
Hand stop valve I 2, hand stop valve II 11, main gas fuel valve I 3 on one supply air line are opened, and wherein one
When the main gas fuel valve II 8 that engine is set is opened, supply air line is wherein one engine supply；
Hand stop valve I 2, hand stop valve II 11, main gas fuel valve I 3 on two supply air lines are opened, and correspondence every
When the main gas fuel valve II 8 that engine is set also is opened, two supply air lines are simultaneously two engine supply；
When wherein one supply air line is leaked, main gas fuel valve I 3, main gas fuel valve II 8 on the supply air line
It is turned off, while main gas fuel valve III 7 was opened have neither part nor lot in engine combustion acting but being present in of having gasified
Gas discharge in pipeline.
When wherein one engine is shut down, to should the main gas fuel valve II 8 that sets of engine close, main gas combustion
Material valve IV 9, which is opened, discharges the gas being present in pipeline still gasified for having neither part nor lot in engine combustion acting.
