During oil produce volatile organic matter (NMHC), its be volatile organic matter main source it
One, if these Organic substances are not controlled by, ambient air quality will be reduced.In consideration of it, " the China people
Republic's Air Pollution Prevention Law " the 47th article of regulation, oil storage gas storage, refueling station and oil truck, gas
Tank car etc., it should install device for recovering oil and gas according to the provisions of the relevant regulations issued by the State and keep normal use.
Gas recovery system for oil refers to by emptying gas recovery system for oil, gasoline sealed storage, oiling petroleum vapor recovery system
System, on-line monitoring system and oil-gas emission treatment device composition.The effect of this system be by gas station emptying,
In oil storage and refueling process produce oil gas, by airtight collection, store and send into oil car tank in,
It is transported to storage tank farm centralized recovery and becomes gasoline.Wherein, secondary oil gas reclaims and refers to oiling gas recovery system for oil.
This stage petroleum vapor recovery realizes process: during gas station is automobile fuel filler, is produced certain by vacuum pump
Vacuum, through oil-gas recovery devices such as nozzle, petroleum vapor recovery pipe, vacuum pumps, according to gas liquid ratio control
Requirement between 1.0 to 1.2, by the petroleum vapor recovery that volatilizees in refueling process to oil tank.Nozzle is equal
Use petroleum vapor recovery type nozzle, flowline is shaped with petroleum vapor recovery hole and the petroleum vapor recovery communicated therewith
Passage, and boring cover (having another name called gas skirt) is set in flowline rearward end, in its refueling process, boring cover is enclosed in
Reservoir port, it is ensured that petroleum vapor recovery reaches relative obturation effect, meets " gas station's atmosphere pollutants emission standards "
Related request.
But in actual refueling process, due to fuel tank type various (the such as fuel tank such as motorcycle, lorry), refuel
Rifle boring cover cannot be enclosed in reservoir port, and nozzle petroleum vapor recovery hole cannot be introduced into fuel tank, causes this petroleum vapor recovery system
System is in inefficacy running status, it is impossible to reach to carry in " gas station's atmosphere pollutants emission standards " discharge standard
" airtight " requirement arrived.And according to " The Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution " the 103rd article of regulation, right
In the device for recovering oil and gas being not normally functioning, 20,000 yuan to the 200000 yuan fine not waited will be sentenced.To this,
Unit of operation of gas station in the urgent need to address above-mentioned cannot be airtight problem.
Comprehensive above analysis, the reclaiming type nozzle petroleum vapor recovery hole caused owing to fuel tank type is various at present is not
Can insert fuel tank, boring cover also cannot cover the problem of fuel tank and bring bigger ring to the daily operation of gas station
Border risk and economic risk.

Accompanying drawing explanation
Fig. 1 is the operation principle schematic diagram of this utility model embodiment.
Detailed description of the invention
The utility model is described in further detail below, but this utility model is not limited to following example.
The auxiliary recovery unit of oiling gas recovery system for oil in gas station's as depicted, under this device includes greatly
Little conical hollow straight tube 1, and be movably connected on tapered hollow straight tube 1 top by helicitic texture
Circular hollow straight tube 2；Tapered hollow straight tube is for being interspersed in tank filler, circular hollow straight tube when refueling
Inner chamber then for nozzle insert.Described helicitic texture is the external screw thread of cone hollow straight tube top external circumference
1-1, and the female thread 2-1 being positioned in tapered hollow straight tube top inner wall and matching with described external screw thread.Spiral shell
Stricture of vagina length of action can determine as required, and the most selected regulation is a length of not less than 5cm.
The outer conical surface of described cone hollow straight tube is circular hollow straight tube less than the oil filler internal diameter of fuel tank
Outer circumference surface is more than the oil filler internal diameter of fuel tank；So when refueling, this utility model can be made to insert and stay
It is parked in the oil filler of fuel tank, for nozzle operation.
Further, for stopping a leak a little, improve sealing property, the outer conical surface of described cone hollow straight tube
On also set up lower rubber seal 1-2 of corrugated tube shape；This rubber seal is around circumferencial direction and connection
Lopping, to increase sealing property between cone hollow straight tube and the oil filler of fuel tank；Described lower rubber seal
Astragal is magnetic (magnetic rubber circle or the General Purpose Rubber circle equipped with Magnet), its in nose-circle week edge be fixed on circle
In the outer conical surface of tapered hollow straight tube, remainder is with being suspended elastically from outside cone hollow straight tube
On taper seat, can rely on during oiling magnetic absorption in the circumference of tank filler, thus tank filler is complete
Full cover cap is closed.
Upper rubber seal 2-2 of a corrugated tube shape is also set up on the outer circumference surface of described circular hollow straight tube, should
Rubber seal is around circumferencial direction and connects lopping, close with increase between circular hollow straight tube and nozzle
Sealing property.The circumferential edge edge, bottom of described upper rubber seal is fixed on the outer circumference surface of circular hollow straight tube,
Then it can be made to engage with the boring cover of nozzle the top pull-up of rubber seal on this during oiling, thus incite somebody to action this
The complete cover cap in gap between utility model and nozzle is closed.
As preferably, the internal diameter of described circular hollow cylinder is more than nozzle peripheral diameter 2-5mm；Described circle
The external diameter of tapered hollow cylinder is less than tank filler internal diameter 2-5mm.
As preferably, described circular hollow cylinder, cone hollow cylinder all use polytetrafluoroethylmaterial material system
Form.
In refueling process, when to when there is the group refueling of tank filler lack of standardization, owing to nozzle is difficult
To go deep in reservoir port, may result in secondary oil gas reclaiming system and lost efficacy.In this case, can be by this reality
Insert reservoir port with novel conical hollow cylinder one end, seal cylinder by drop-down for lower rubber seal simultaneously
And the gap between tank filler sleeve, carries magnetic sealing ring i.e. to can be adsorbed on oil filler periphery and plays fixing support work
With, then reclaiming type nozzle is inserted in circular hollow cylinder, and upper rubber seal pull-up is made it and adds
The gas skirt of oil gun combines to be closed, and can start to refuel.
Above-described embodiment is used for illustrating this utility model rather than limiting this utility model, this
In the spirit of utility model and scope of the claims, any amendment that this utility model is made and changing
Become, both fall within protection domain of the present utility model.
