Description
Technical field
The utility model relates to a kind of petroleum vapor recovery disconnector, particularly a kind of silk string mist eliminator of single gun oil gas recovery separator, is reclaimed by oil gas volatilization in transport, storage process for gasoline.
Background technology
Along with the fast development of economy and the soaring rapidly of car owning amount, being becoming tight petroleum-based energy supply day of China, also increases day by day to the dependence of external crude oil import, according to statistics, Chinese Crude Oils in 2004 and imported crude oil total amount about 2.9 hundred million tons, wherein light imported crude oil just reaches 1.2 hundred million tons.But the problem of the oil gas volatilization of gasoline in transport, storage process not yet causes our enough attention.According to CARB(California Air Resources association) detection of petrol service station (not installing device for recovering oil and gas) is shown, the gasoline that the gasoline often selling 1000 gallons (close 2952kg) has 0.84 pound (0.38kg) by breather loss, separately has the gasoline of 8.4 pounds (3.8kg) can because of volatilizing loss in the process of refueling from oil tank.Exhaust of oil amount in oil tank region is also very large: temperature often raises 1 degree Celsius, and gasoline can discharge the oil gas of 0.21%, and store number of days more, in tank, oil gas volume is larger with the ratio of fluid volume; If 2,000,000 tons of oil leave in degree of utilization be 50% oil tank in 30010 degrees Celsius, just have cubic meter more than 550,000 (660 tons) exhaust of oil in air.
Domestic data also shows, within 2003, the whole nation consumes 5,000 ten thousand tons, gasoline, and at least discharge 2.8 billion cubic meters (340,000 tons) oil gas in running, pin process, the economic loss that oil gas volatilization causes is up to 1,300,000,000 Renminbi; And according to incompletely statistics, the economic loss that China in 2004 causes because of oil gas volatilization is up to 2,000,000,000 Renminbi, oil gas volatilization can produce a large amount of high saturated humidity oil gas, if encounter Mars or electrostatic will be blasted, this all brings great potential safety hazard to oil tank battery and petrol service station etc.The petrol service station of some business districts starts the nozzle that mounting strap reclaims device of air now, although solve the oil gas volatilization problem that the end that refuels a car produces, but because the oil gas drawn back is not through recycling, focus mostly on greatly and again to be discharged by breathing helmet, so fundamentally do not eliminate safe hidden trouble.
Utility model content
It is low that the purpose of this utility model is to provide a kind of price, petroleum vapor recovery good separating effect, the silk string mist eliminator of a kind of single gun oil gas recovery separator easy for installation.
The purpose of this utility model is achieved in that a kind of silk string mist eliminator of single gun oil gas recovery separator, it is characterized in that: comprise end cap, cylindrical shell and silk string module composition; The perforate of cylinder body bottom band negative thread, cylindrical shell top is straight tube, outer bands outside thread; Straight thread perforate is arranged at end cap top; End cap sealing has negative thread; Place silk string module in cylindrical shell, end cap sealing negative thread is connected with cylindrical shell tip male thread matching thread.
Described end cap external diameter is 34mm, and cylindrical shell external diameter is 30mm.
Described end cap crown center adopts the perforate of G1/4 straight thread; The perforate of G1/4 straight thread is adopted in the middle of cylinder body bottom.
After described end cap is connected with cylindrical shell, length is at 50 ± 1mm.
Described silk string module is made up of lipophilic material and metal filament.
Described end cap crown center adopts the perforate of G1/4 straight thread to adopt G1/4 straight thread opening axis to overlap with in the middle of cylinder body bottom.
Silk string mist eliminator is used for, in a kind of single gun oil gas recovery separator, solving the oil gas volatilization problem that automobile fuel filler end produces, and fundamentally eliminating safe hidden trouble.
Overall working process is: utilize existing vacuum pump to connect inlet suction port, and by admission port to separative element, separative element comprises coalescent and UF membrane two links, make the gas mixture of admission port end coalescent with the effect of film under carry out first time Oil-gas Separation; After being separated, oil is through reducer union leakage fluid dram, enters petrol service station liquid collecting tank and reclaims.The rear gas of separation enters silk string mist eliminator by T-pipe joint and carries out secondary oil gas separation; Oil after secondary separation enters petrol service station liquid collecting tank and reclaims.Gas after secondary separation enters air through exhausr port.
The utility model advantage is: because oil gas carries out flash liberation through coalescent and film, coalescent with film compared with existing absorption and sorption, condensation process, have that cost is low, structure simply, the feature of good manufacturability.Single rifle takes full advantage of existing reclaiming scrap simultaneously, reduces engineering cost.
The utility model with make into reclaim nozzle but the equipment being unkitted Oil-gas Separation unit compares, really reach petroleum vapor recovery, clean emission, realize the object of petroleum vapor recovery.
