Abstract
The utility model relates to a crude oil storage tank sealing device belongs to crude oil storage tank oil gas sealing technique field. The utility model relates to a jar body, a jar body welding has interior baffle, air chamber and back air chamber before interior baffle is separated the jar body become, preceding air chamber and back air chamber lower part intercommunication, install the intake pipe on the tank deck of preceding air chamber, gas vent and overflow mouth have been opened from top to bottom respectively to the jar wall upper portion of back air chamber. The utility model discloses utilize seal liquid effectually to keep apart volatility oil gas in the crude oil storage tank and air, both reduced former oil loss, reduced the pollution of incident hidden danger and environment again, be particularly suitable for the vault crude oil storage tank that the oil field position is dispersed, the storage capacity is less and use, have very strong practicality.
Description
technical field:
The utility model relates to a kind of crude oil storage tank sealing arrangement, belongs to crude oil storage tank sealing hydrocarbons technical field.
background technology:
At present, the crude oil of each field produces is stored in crude oil storage tank after multi-purpose station is stable.Existing crude oil storage tank comprises Dome roof tank and floating roof tank.Dome roof tank is non-pressure vessel, and when temperature raises or crude oil fills, the volatility oil gas in storage tank discharges sky through the spiracle of tank deck, has both caused crude oil loss, there is again the defect of the pollution of safety hazards and environment; Floating roof tank is mainly used in Petrochemical Enterprises and oil storage, and its crude oil amount stored is relatively large, invests high, is not suitable for being applied to the relatively little multi-purpose station of crude oil amount.
summary of the invention:
The purpose of this utility model is discharged sky in order to the volatility oil gas overcome in the Dome roof tank that uses in above-mentioned prior art, crude oil is caused to lose, there is the defect of the pollution of safety hazards and environment, provide a kind of and invest crude oil storage tank sealing arrangement little, effective sealing can be carried out to the volatility oil gas in Dome roof tank.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The utility model is a tank body, and tank body welding has internal partition, and tank body is separated into front air chamber and rear gas chamber by internal partition, and front air chamber is communicated with rear gas chamber bottom; The tank deck of front air chamber is provided with air inlet pipe, and the tank skin top of rear gas chamber has exhausr port and outgate from top to bottom.
The utility model utilize seal fluid can actv. by the volatility oil gas in crude oil storage tank and air insulated, both crude oil loss had been reduced, additionally reduce the pollution of safety hazards and environment, be particularly suitable for the vault crude oil storage tank that field situation disperses, storage capacity is less to use, there is very strong practicality.
accompanying drawing illustrates:
Fig. 1 is the utility model structural front view.
detailed description of the invention:
Composition graphs 1 pair of the utility model is described in detail:
The utility model is a tank body 3, and tank body 3 is welded with internal partition 4, and tank body 3 is separated into front air chamber 9 and rear gas chamber 10 by internal partition 4, and front air chamber 9 is communicated with rear gas chamber 10 bottom; The tank deck of front air chamber 9 is provided with air inlet pipe 1, and the tank skin top of rear gas chamber 10 has exhausr port 2 and outgate 8 from top to bottom.
The floor space of the front air chamber 9 in described tank body 3 is greater than the floor space of rear gas chamber 10.
Described tank body 3 is provided with coolant inlet pipe 6, the seal fluid in tank body 3 can be supplemented in time; Drain hose 7 is arranged on the bottom of tank body 3, by its switch of Valve controlling, and can seal fluid in emptying tank body 3.
The tank skin of described tank body 3 is provided with liquidometer 5, the liquid level of the seal fluid in tank body 3 can be observed at any time.
Be connected with crude oil storage tank spiracle by conduit by the admission port 1 of tank body 3 of the present utility model, liquidometer mouth 5 is connected with liquidometer, and discharge port 7 is connected with sluicing valve, and water inlet 6 is connected with flood valve, and exhausr port 2 connects freeing pipe, and outgate 8 is connected with overflow pipe.Close tank body 3 bottom discharge mouth 7 valve, open inlet valve to water filling in tank body 3, after setting up certain liquid level, close inlet valve; When the pressure increase in crude oil storage tank, in crude oil storage tank, oil gas enters air chamber 9 before tank body 3 by storage tank spiracle, connecting duct, liquid level in front air chamber 9 is declined, rear gas chamber 10 liquid level rises, because two air chamber sectional areas are different, rear gas chamber 10 liquid level ascending velocity, much larger than front air chamber 9 descending speed, forms higher fluid column static pressure in rear gas chamber 10, thus realizes sealing hydrocarbons; When crude oil storage tank internal pressure continues to increase, when rear gas chamber 10 water column is elevated to outgate 8, water automatic overflow, avoids superpressure in crude oil storage tank; When crude oil exporting in crude oil storage tank or temperature reduce, when crude oil storage tank internal pressure declines, rear gas chamber 10 water level falls after rise, lower liquid level is formed at front air chamber 9, extraneous gas is easy to break through water seal in front air chamber 9 and enters front air chamber 9, then enter in crude oil storage tank, avoid negative pressure in crude oil storage tank excessive.
