Description
Technical field
This utility model relates to environmental conservation and field of energy-saving technology, in particular to a kind of gas station
Secondary oil gas retracting device.
Background technology
Gasoline is the light-end products of a kind of highly volatile, storing, load and unload, transport, retail
Cheng Zhong, can produce oil gas.Volatilization is to the oil gas in the middle of air, not only to nearby residents
Work the mischief, pollute surrounding enviroment, there is also the potential danger of breaking out of fire explosion accident.
The oil gas of gas station produces mainly two approach: one is that oil truck is when buried tank unloads gasoline
With what is called " the breathe greatly " process added to motor vehicles during gasoline, two be in oil tank oil volume and
Oil gas volume raises with temperature and what is called " little breathing " process during flatulence of heat type, " breathing greatly " mistake
The exhaust of oil amount of journey is considerably beyond the discharge capacity of " little breathing " process.
Reclaim " breathing greatly " oil gas that process produces, mainly include two processes, an oil gas
Removal process and secondary oil gas removal process.Petroleum vapor recovery process is that oil truck is to subterranean oil
When tank unloads gasoline, by the pipeline of airtight connection, the oil gas that buried tank is cemented out, receive
Process in collection oil-feed tank car, when secondary oil gas removal process is to add gasoline to motor vehicles, passes through
The pipeline of airtight connection is by the process in oil gas collection to buried tank.The Japan energy resource Room
Investigation report shows, oil truck, when gas station's buried tank emptying, the most often unloads 1m3Vapour
Oil, the evaporating loss of gasoline is 1.08Kg, and fuel charger is when motor vehicles refuels, often adds 1m3
Gasoline, the evaporating loss of gasoline is 1.44Kg, is the oiling of 10,000 tons to annual turnover
Stand, because the oil loss of exhaust of oil reaches 22.6 tons.As can be seen here, the recovery of secondary oil gas is outstanding
For important, device for recovering oil and gas is possible not only to reduce oil vapour pollution, it is also possible to reduce oil product loss,
Therefore device for recovering oil and gas is installed by gas station, is to take into account the dual effect of environmental protection and economy.In order to
