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 is the gas-phase space pipeline communication of multiple storage tanks of same oil product together, increase gas-phase space volume, when the gas that any one storage tank is discharged because receiving oil can be while, another storage tank of outer hair oil held, realize not to air or few to airborne release, thus reduce breather loss.
Existing gas phase communication apparatus (as CN201510185742.0) is directly linked together by the gas-phase space of multiple storage tank with pipeline, and pass into nitrogen at gas-phase space, and increase gas recovery system for oil.The shortcoming of this mode needs to consume nitrogen, and need the process problem considering storage tank upper strata space gases.
The present invention solves this problem targetedly.
Summary of the invention
Technical matters to be solved by this invention be in prior art flow process complicated, consume nitrogen and cannot the problem of reuse, a kind of new storage tank gas phase communication apparatus is provided.This device is used for, in storage tank, having the advantage that flow process simply, does not consume nitrogen.
For solving the problem, the technical solution used in the present invention is as follows: a kind of storage tank gas phase communication apparatus, main pipe line before comprising admission line, air inlet water sealed tank, storage tank, enter tank line, go out tank line, main pipe line, water sealed tank of giving vent to anger, pipeline of giving vent to anger, storage tank, flame trap after storage tank, admission line is fuel gas admission line, and air inlet water sealed tank is the water sealed tank arranged on admission line; Before storage tank, main pipe line is the fuel gas main pipe line of admission line after water sealed tank; Entering tank line is the by-pass line that main pipe line is connected to each storage tank before storage tank; Going out tank line is the pipeline of giving vent to anger of drawing from each storage tank; After storage tank main pipe line be each is gone out tank line gather after fuel gas main pipe line; Water sealed tank of giving vent to anger is the water sealed tank that storage tank rear line is arranged; Pipeline of giving vent to anger is after water sealed tank of giving vent to anger, is connected to the pipeline of Petrochemical Enterprises low pressure flare pipe network; Enter tank line, go out on tank line and all flame trap is installed.
In technique scheme, preferably, storage tank is the tank body having volatile substances.
In technique scheme, preferably, before storage tank, main pipe line is provided with compression indicator.
In technique scheme, preferably, go out tank line and be connected with water sealed tank of giving vent to anger, or go out tank line and be connected with water sealed tank of giving vent to anger after main pipe line after storage tank.
Tool of the present invention has the following advantages: (1) the present invention adopts Petrochemical Enterprises fuel gas as the blanketing gas of sheaf space on storage tank, has saved the use of nitrogen; (2) due to employing fuel gas and without nitrogen, the fuel gas that storage tank is discharged does not need can be back to Petrochemical Enterprises fuel gas through any process, eliminates gas recovery system for oil; (3) air inlet and all employing water sealed tanks of giving vent to anger control, and achieve essential safety on the one hand, avoid the control cock adopting cost higher on the other hand, reduce investment, achieve good technique effect.
Accompanying drawing explanation
Fig. 1 is one of schematic flow sheet of device of the present invention;
Fig. 2 is the schematic flow sheet two of device of the present invention.
In Fig. 1, Fig. 2, before 1 admission line, 2 air inlet water sealed tanks, 3 storage tanks main pipe line, 4 enter tank line, 5 go out tank line, 6 storage tanks after main pipe line, 7 water sealed tank, 8 of giving vent to anger to give vent to anger pipeline, 9 storage tanks, 10 compression indicators, 11 flame traps.
Below by embodiment, the invention will be further elaborated, but be not limited only to the present embodiment.
Detailed description of the invention
[embodiment 1]
A kind of storage tank gas phase communication apparatus as shown in Figure 1, main pipe line 3 before it comprises admission line 1, air inlet water sealed tank 2, storage tank, enter tank line 4, go out tank line 5, storage tank after main pipe line 6, water sealed tank 7 of giving vent to anger, give vent to anger pipeline 8, four storage tanks 9, compression indicator 10, flame traps 11.
Admission line is fuel gas admission line, and air inlet water sealed tank is the water sealed tank arranged on admission line; Before storage tank, main pipe line is the fuel gas main pipe line of admission line after water sealed tank; Entering tank line is the by-pass line that main pipe line is connected to each storage tank before storage tank; Going out tank line is the pipeline of giving vent to anger of drawing from each storage tank; After storage tank main pipe line be each is gone out tank line gather after fuel gas main pipe line; Water sealed tank of giving vent to anger is the water sealed tank that storage tank rear line is arranged; Pipeline of giving vent to anger is after water sealed tank of giving vent to anger, is connected to the pipeline of Petrochemical Enterprises low pressure flare pipe network; Enter tank line, go out on tank line and all flame trap is installed.
When any one or more in 4 storage tanks 9 cause that amount of evaporation of oil gas raises owing to receiving reason such as oil operation, temperature rising etc., the rising of storage tank upper pressure time, oil gas can along going out main pipe line 6 after tank line 5 to storage tank, break through the water seal of water sealed tank 7 of giving vent to anger, enter pipeline 8 of giving vent to anger, thus send into full factory fuel gas pipe network.
When any one or more in 4 storage tanks 9 cause storage tank upper pressure to reduce because hair oil operation or temperature reduce, the fuel gas come from admission line will break through the water seal of air inlet water sealed tank, thus by main pipe line before storage tank 3 with enter tank line 4 for storage tank 9 postcombustion gas.
The elevation of water surface of air inlet water sealed tank 2 is determined by the low pressure limit of storage tank 9.
The elevation of water surface of water sealed tank 7 of giving vent to anger is determined by the upper pressure limit of storage tank 9.
When pipeline is due to any possible situation initiation fire, flame can be extinguished by flame trap 11, thus the impact on other storage tanks after avoiding a storage tank presence of fire.
Compression indicator 10 moment on pipeline monitors the pressure of whole storage tank gas phase intercommunicating device, when pressure exceedes the upper limit or lower automatic alarm in limited time.
[embodiment 2]
According to the condition described in embodiment 1, adopt device as shown in Figure 2, when any one or more in 4 storage tanks 9 cause that amount of evaporation of oil gas raises owing to receiving reason such as oil operation, temperature rising etc., the rising of storage tank upper pressure time, oil gas can along going out after tank line 5 to each storage tank in corresponding water sealed tank 7, break through the water seal of water sealed tank 7 of giving vent to anger, enter main pipe line 6, then enter pipeline 8 of giving vent to anger, thus send into full factory fuel gas pipe network.
Obviously, adopt the solution of the present invention, adopt Petrochemical Enterprises fuel gas as the blanketing gas of sheaf space on storage tank, saved the use of nitrogen; Due to employing fuel gas and without nitrogen, the fuel gas that storage tank is discharged does not need can be back to Petrochemical Enterprises fuel gas through any process, eliminates gas recovery system for oil; Air inlet and all employing water sealed tanks of giving vent to anger control, and achieve essential safety on the one hand, avoid the control cock adopting cost higher on the other hand, reduce investment, achieve good technique effect.
