Abstract
The utility model relates to an oil-gas recovery system which efficiently recovers the oil gas produced during the process of loading oil to the tank truck. The system comprises a stock tank 3, an oil outlet pipe 5, a fuel truck gas outlet pipe 6, and a gas pressure indicating adjustment controller 8. The system is characterized in that the fuel truck gas outlet pipe 6 connects with the stock tank through an air-return pipe 4, and an air pump 10 and an air back valve 11 are connected with the air-return pipe 4. The gas pressure indicating adjustment controller 8 connects to the air pump 10 and controls the operation of the air pump, or the gas pressure indicating adjustment controller 8 connects to an air back valve 11 and controls the operation of the air back valve. The utility model has simple structure and demands low for the handling property of the oil gas processing unit so as to reduce the investing cost of the oil correspondingly. The system has two advantages. Firstly the useful but volatile gas can be recovered so that the resources are saved. Secondly nature is kept from being contaminated, so the system is beneficial to entironment.
Description
Technical field
The utility model relates to the gas recovery system for oil that the oil gas that produced in a kind of process to truck tanker can oil plant effectively reclaims.
Background technology
Existing truck tanker normally passes through oil outlet pipe can oil plant from large-scale oil storage tank, but, in the oil plant pouring process, can produce a large amount of oil gas, if oil gas is diffused in the air, can be abnormally dangerous, so, require each oil plant storehouse that the oil gas processing equipment must be set oil gas is carried out separating treatment, guarantee that the content of oil is lower than 25g/m after treatment
3The time, just meet the requirements, allow in air, to discharge.But, reach standard like this, then the structure of oil gas processing equipment is very complicated, and treatment process is loaded down with trivial details, and cost of investment is big, the disposal cost height.
Technical scheme
At above-mentioned the deficiencies in the prior art, the purpose of this utility model is the gas recovery system for oil that oil gas that design is produced in a kind of process to truck tanker can oil plant effectively reclaims, it requires low to the processing capacity of oil gas processing equipment, and, treated oil gas is not discharged in atmosphere, but directly feed back in the petrol storage tank, reduce the danger of oil gas significantly.
The technical scheme that realizes above-mentioned purpose is, a kind of gas recovery system for oil, comprise petrol storage tank 3, oil outlet pipe 5, truck tanker freeing pipe 6, gaseous tension indication adjustment control 8, it is characterized in that: described truck tanker freeing pipe 6 returns by muffler 4 and is connected on the petrol storage tank, is serially connected with air pump 10, return-air valve 11 in muffler 4; Gaseous tension indication adjustment control 8 connects air pump 10, and the operation of control air pump, and perhaps, gaseous tension indication adjustment control 8 connects return-air valve 11, and the operation of control return-air valve.
Further, between truck tanker freeing pipe 6 and muffler 4, be provided with oil gas processing equipment 9.
The utlity model has simple in structurely, the handling property of oil gas processing equipment is required low, reduce the cost of investment in oil plant storehouse accordingly, and have advantage: can reclaim highly volatile valuable gases on the one hand, save resource; It is contaminated to protect nature on the other hand, helps ecology environment.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Specific implementation
See also figure, usually in the oil plant storehouse, be provided with large-scale petrol storage tank 3, there are oil inlet 1 and breathing valve 2 in the upper end of existing petrol storage tank, in the lower end of petrol storage tank oil outlet pipe 5 is arranged, oil outlet pipe is connected with the charge of oil mouth of truck tanker 7 by adding oil crane tube, and the air extractor duct of truck tanker connects truck tanker freeing pipe 6, and all oil gas of being discharged by truck tanker freeing pipe 6 are admitted to and carry out separating treatment in the oil gas processing equipment 9.8 pairs of oil gas processing equipment 9 of gaseous tension indication adjustment control are controlled.More than be that existing oil gas is handled recovery technology.The utility model comes down to add a muffler 4 in oil gas processing equipment 9 backs and is connected with the petrol storage tank upper end, is not directly to be discharged in the atmosphere with the oil gas after handling, but is recirculated directly back in the petrol storage tank.Be serially connected with air pump 10, return-air valve 11 in muffler 4, gaseous tension indication adjustment control 8 connects air pump 10, and the operation of control air pump.
In the above-described embodiments, can also handle, directly oil gas be sent back in the petrol storage tank without 9 pairs of oil gas of oil gas processing equipment.
When the filling tank car, be closed state owing to add the charge of oil mouth of oil crane tube and truck tanker, so pour into the oil of truck tanker the oil gas in it is discharged from truck tanker under the effect of air pump, entering 9 pairs of oil gas of oil gas processing equipment by truck tanker freeing pipe 6 handles, the liquefaction of part oil gas, remaining gas enter by muffler 4 and air pump 10 and replenish in the petrol storage tank because the gas compartment that oil extraction produces.Like this, total system is in the state of a balance and stability basically.Wherein, gaseous tension indication adjustment control 8 is also controlled the operation of air pump 10 or return-air valve 11 when oil gas processing equipment 9 is controlled.
If the volume of effluent oil is Q from petrol storage tank, enter that the gas volume of its volatilization is A behind the truck tanker, the gas volume B (air) that discharges from truck tanker, C (aqueous vapor), D (oil gas) then must have Q=A+B+C+D.Existing processing mode is to make every effort to A+C+D is reduced to zero, and this mode has high requirement to processing equipment, and is difficult to realize that cost is high, and the large-scale oil plant storehouse that has singly is that the oil gas processing equipment will be invested up to ten million yuans.The utility model is to add a muffler to be connected with the petrol storage tank upper end behind the oil gas processing equipment, gets back in the petrol storage tank through the gas volume V≤Q that handles after reclaiming, and breathing valve is in suction condition.Like this, total system is in the state of a balance and stability basically.Simultaneously, this system simplifies the processing equipment manufacturing to the difficulty of oil gas processing equipment, and investment cost can reduce significantly.
