Position on line.
The entrance of first diluent gas pipe 2 is equipped with the first speed governing valve 3；The entrance of surge tank 7 is equipped with shut-off valve 71.
First sensor 5, second sensor 5a, the first speed governing valve 3, the second speed governing valve 6 and shut-off valve 71 are separately connected control
Device 4 processed.The density of hydrogen data measured can be passed to the controller 4 by first sensor 5 and second sensor 5a, described
Controller 4 can control the first speed governing valve 3, the second speed governing valve 6 and shut-off valve 71.
First speed governing valve 3 controls the air inflow of the first diluent gas pipe 2, it is preferred that and it is normal smaller, it can increase；Second
Speed governing valve 6 controls the gas flow that main channel first segment is flowed to second segment, it is preferred that usually larger, minimum can close；It cuts
Only valve 71 controls the gas flow that main channel first segment flows to surge tank 7, usually closes, can open.
When normal work, hydrogen from exhaust emissions port 1 enter main channel, diluent gas from the first diluent gas pipe 2 into
Enter main pipeline, the amount of diluent gas is much larger than the amount of hydrogen, and the two is mixed in the first segment of main pipeline, the concentration of hydrogen after mixing
Lower than the lower limit 4% of explosion limit.The diluent gas can be fuel battery negative pole exhaust gas, be also possible to compressed air or its
His incombustible gas.
For simulation model for mixing gases flows at sensor 5, the concentration values measured are transferred to controller 4.Since concentration is met the requirements,
Shut-off valve 71 is closed, and the second speed governing valve 6 is opened, and mixed gas flows into main channel second segment, and then is discharged from main channel outlet.It can
Infer, the numerical value that second sensor 5a is measured also is met the requirements.

Body.Also, the numerical value that first sensor 5 detects is higher, and controller 4 is just by the first speed governing valve 3 the first diluent gas pipe 2
Flow velocity tune it is higher.
If the emission frequency of hydrogen increases suddenly, short time bulk gas enters main channel first segment, and at this moment first is dilute
The gas for releasing the offer of flue 2 is not enough to dilute under the concentration to explosion limit of hydrogen, when mixed gas passes through sensor 5,
The numerical value real-time delivery measured is to controller 4.Since numerical value is overproof, sensor 4 controls the second speed governing valve 6 and closes, and opens simultaneously
Shut-off valve 71, the higher mixed gas of concentration then enter surge tank 7.At the same time, the first speed governing valve 3 of regulation makes the first carrier gas
The air inflow of body pipe 2 keeps maximum.

It keeps shut-off valve 71 to close, the second speed governing valve 6 is kept to open, while air pressure is insufficient to allow relief valve 74 to open.Mixed gas stream
Enter main channel second segment, and then is discharged from main channel outlet.It is contemplated that, the numerical value that second sensor measures also is met the requirements.
If the emission frequency of hydrogen increases suddenly, short time bulk gas enters main channel first segment, and at this moment first is dilute
The gas for releasing the offer of flue 2 is not enough to dilute under the concentration to explosion limit of hydrogen, when mixed gas passes through sensor 5,
The numerical value real-time delivery measured is to controller 4.Since numerical value is overproof, sensor 4 controls the second speed governing valve 6 and closes, and opens simultaneously
Shut-off valve 71, the higher mixed gas of concentration then enter surge tank 7.At the same time, the first speed governing valve 3 of regulation makes the first carrier gas
The air inflow of body pipe 2 keeps maximum.
The density of hydrogen data that controller 4 is transmitted according to sensor 5, control third speed governing valve 73 adjust the second diluent gas
