Skid topping up device gas recovery system for oil
(1) technical field
The utility model relates to a kind of topping up device, is specifically related to a kind of skid topping up device gas recovery system for oil.
(2) background technology
The filling station is made of buried normal pressure petrol storage tank and tax control fuel charger usually.Being embedded in for a long time of buried petrol storage tank is underground, in case tank skin or transport pipe leak, is difficult to be found, and its consequence is hardly imaginable; And this petrol storage tank is embedded in underground, and its investment is big, floor area is big, and very flexible, and the specific land used that makes such as less and airport is all not too suitable for the suburb vehicle pass-through.Arise at the historic moment in order to overcome above-mentioned not enough skid-mounted type topping up device, but existing skid-mounted type topping up device is fuel charger and petrol storage tank to be grouped together realize adding functional oil, it all is the below that is placed on pipeline that its oil gas reclaims usually, be provided with the oil gas recovery well, be so-called collector tank, in the refueling process, have oil gas volatilization in atmosphere, there is bigger potential safety hazard in the time of the waste resource, and causes environmental pollution easily.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of skid topping up device gas recovery system for oil safe, that can not pollute, economize on resources ambient environment is provided.
The purpose of this utility model is achieved in that a kind of skid topping up device gas recovery system for oil, and it comprises horizontal petrol storage tank, it is characterized in that: it also comprises fuel charger panel, submersible pump, fuel filler pipe and oil gun;
Described petrol storage tank is provided with the fuel charger panel, and described fuel charger panel is provided with oil gun, is provided with submersible pump in the described petrol storage tank, and described submersible pump mouth is connected with oil gun by fuel filler pipe; Be connected with the oil gas Through Flow Line (TFL) on the Pull breaking ualve of described oil gun, described oil gas Through Flow Line (TFL) links to each other with petrol storage tank top oil and gas import, and described oil gas Through Flow Line (TFL) is provided with oil gas and reclaims pump, and described petrol storage tank top is provided with pneumatic breathing valve.
Described fuel charger panel is arranged at middle part, described petrol storage tank the place ahead, fuel charger panel and can body paste and.
Compared with prior art, the beneficial effects of the utility model are:
Oil gas reclaims pump and open work simultaneously when fuel loading system is refueled, and the form that it takes negative pressure oil gas of generation when refueling is recovered in the petrol storage tank, does not allow oil gas volatilization in atmosphere, has avoided the generation of dangerous accident, has also protected environment, has saved resource.
