Description
Technical field
The present invention relates to a kind of storage tank gas phase communication apparatus.
Background technology
Storage tank gas phase communication apparatus be the gas-phase spaces of multiple storage tanks of same oil product with pipeline communication together, increase
Big gas-phase space volume, when the gas that any one storage tank is discharged because receiving oil can be held by another storage tank of outer hair oil simultaneously
Receive, realize not to air or few to air discharge, so as to reduce loss through breathing.
Existing gas phase communication apparatus (such as CN201510185742.0) is empty directly by the gas phase of multiple storage tanks with pipeline
Between link together, and be passed through nitrogen in gas-phase space, and increase gas recovery system for oil.The shortcomings that this mode is to need to consume
Nitrogen, and need to consider the process problem of storage tank upper strata space gases.
The present invention targetedly solves the problem.
The content of the invention
The technical problems to be solved by the invention be in the prior art flow is complicated, consumption nitrogen and can not reuse ask
A kind of topic, there is provided new storage tank gas phase communication apparatus.Flow is simple, does not consume the excellent of nitrogen in storage tank, having for the device
Point.
To solve the above problems, the technical solution adopted by the present invention is as follows：A kind of storage tank gas phase communication apparatus, including air inlet
Main pipe line before pipeline, air inlet water sealed tank, storage tank, enter tank line, go out tank line, storage tank after main pipe line, outlet water sealed tank, go out
Gas pipeline, storage tank, spark arrester, admission line are fuel gas admission line, and air inlet water sealed tank is the water set on admission line
Sealed cans；Main pipe line is fuel gas main pipe line of the admission line after water sealed tank before storage tank；It is from the preceding house steward of storage tank to enter tank line
Line is connected to the by-pass line of each storage tank；It is the outlet line drawn from each storage tank to go out tank line；Main pipe line is to incite somebody to action after storage tank
It is each go out tank line collect after fuel gas main pipe line；Outlet water sealed tank is the water sealed tank set on storage tank rear line；Outlet
Pipeline for after outlet water sealed tank, be connected to the pipeline of Petrochemical Enterprises low pressure flare pipe network；Enter tank line, go out on tank line
Spark arrester is installed.
In above-mentioned technical proposal, it is preferable that storage tank is the tank body for having volatile substances.
In above-mentioned technical proposal, it is preferable that pressure gauge is installed before storage tank on main pipe line.
In above-mentioned technical proposal, it is preferable that go out tank line and be connected with outlet water sealed tank, or go out tank line after storage tank
It is connected after main pipe line with outlet water sealed tank.
The invention has the advantages that：(1) present invention uses sealing of the Petrochemical Enterprises fuel gas as sheaf space on storage tank
Gas, the use of nitrogen is saved；(2) due to using fuel gas and not having to nitrogen, the fuel gas of storage tank discharge is not required to by appointing
Where reason can be back to Petrochemical Enterprises fuel gas, eliminate gas recovery system for oil；(3) air inlet and outlet are entered using water sealed tank
Row control, on the one hand realizes essential safety, on the other hand avoids, using the higher control valve of cost, reducing investment, obtaining
Preferable technique effect.
Brief description of the drawings
Fig. 1 is one of schematic flow sheet of device of the present invention；
Fig. 2 is the two of the schematic flow sheet of device of the present invention.
In Fig. 1, Fig. 2, main pipe line before 1 admission line, 2 air inlet water sealed tanks, 3 storage tanks, 4 enter tank line, 5 go out accumulator
Main pipe line, 7 outlet water sealed tanks, 8 outlet lines, 9 storage tanks, 10 pressure gauges, 11 spark arresters after line, 6 storage tanks.
Below by embodiment, the invention will be further elaborated, but is not limited only to the present embodiment.
Embodiment
【Embodiment 1】
A kind of storage tank gas phase communication apparatus as shown in Figure 1, it is including total before admission line 1, air inlet water sealed tank 2, storage tank
Pipeline 3, enter tank line 4, go out tank line 5, storage tank after main pipe line 6, outlet water sealed tank 7,8, four storage tanks 9 of outlet line,
Pressure gauge 10, spark arrester 11.
Admission line is fuel gas admission line, and air inlet water sealed tank is the water sealed tank set on admission line；Before storage tank
Main pipe line is fuel gas main pipe line of the admission line after water sealed tank；It is that main pipe line is connected to each storage before storage tank to enter tank line
The by-pass line of tank；It is the outlet line drawn from each storage tank to go out tank line；After storage tank main pipe line be by it is each go out accumulator
The fuel gas main pipe line of the congruence General Logistics Department；Outlet water sealed tank is the water sealed tank set on storage tank rear line；Outlet line is in outlet
After water sealed tank, it is connected to the pipeline of Petrochemical Enterprises low pressure flare pipe network；Enter tank line, go out to be mounted on back-fire relief on tank line
Device.
When any one or more in 4 storage tanks 9 cause amount of evaporation of oil gas due to receiving the reasons such as oil operation, temperature rise
When rise, the rise of storage tank upper pressure, oil gas can break through outlet water sealed tank 7 along main pipe line 6 after tank line 5 to storage tank is gone out
Water seal, into outlet line 8, so as to be sent into full factory's fuel gas pipe network.
When any one or more in 4 storage tanks 9 because hair oil operation or temperature reduction cause storage tank upper pressure to drop
When low, the fuel gas come from admission line will break through the water seal of air inlet water sealed tank, so as to by main pipe line before storage tank 3 and enter storage
Tank pipeline 4 is that storage tank 9 supplements fuel gas.
The height of water level of air inlet water sealed tank 2 is determined by the low pressure limit of storage tank 9.
The height of water level of outlet water sealed tank 7 is determined by the upper pressure limit of storage tank 9.
When pipeline triggers fire due to any possible situation, flame can be extinguished by spark arrester 11, so as to avoid one
Influence of the concrete on fire to other storage tanks occurs for individual storage tank.
Moment of pressure gauge 10 on pipeline monitors the pressure of whole storage tank gas phase intercommunicating device, when pressure exceed the upper limit or under
Automatic alarm in limited time.
【Embodiment 2】
According to the condition described in embodiment 1, using device as shown in Figure 2, when any one in 4 storage tanks 9 or more
Individual when causing amount of evaporation of oil gas rise, the rise of storage tank upper pressure due to receiving the reasons such as oil operation, temperature rise, oil gas can be along
Go out after tank line 5 to each storage tank in corresponding water sealed tank 7, break through the water seal of outlet water sealed tank 7, into main pipe line 6, then
Into outlet line 8, so as to be sent into full factory's fuel gas pipe network.
Obviously, using the solution of the present invention, using sealing gas of the Petrochemical Enterprises fuel gas as sheaf space on storage tank, section
The about use of nitrogen；Due to using fuel gas and not having to nitrogen, the fuel gas of storage tank discharge is not required to by any processing
Petrochemical Enterprises fuel gas is back to, eliminates gas recovery system for oil；Air inlet and outlet are controlled using water sealed tank, on the one hand
Essential safety is realized, on the other hand avoids, using the higher control valve of cost, reducing investment, achieves preferable technology effect
Fruit.
