Single gun oil-gas recovery separator

Abstract

The present invention relates to a single gun oil-gas recovery separator, which is characterized by at least comprising a filter cylinder, a gas inlet joint and a connection joint, wherein an accumulation filtration unit is fixed inside the filter cylinder, the accumulation filtration unit is packaged in the filter cylinder through the upper cover and the lower cover by both ends of the filter cylinder, the upper cover is connected with the gas inlet joint, the lower cover is connected with the connection joint, the gas inlet joint and the connection joint are arranged on both ends of the filter cylinder, the gas inlet joint, the filter cylinder, the accumulation filtration unit and the connection joint form a first filtration body, and the separated gas-liquid enters from the gas inlet of the gas inlet joint and is discharged from the connection joint. The single gun oil-gas recovery separator has characteristics of low cost, simple structure and good process, wherein the existing recycling equipment is completely utilized so as to reduce the engineering cost.

Description

Technical field [0001] The invention relates to an oil and gas recovery separator, in particular to a single-gun oil and gas recovery separator, which is used for volatilizing and recovering oil and gas during gasoline transportation and storage. Background technique [0002] With the rapid economic development and the rapid increase in car ownership, China's petroleum energy supply is becoming increasingly tight, and its dependence on foreign crude oil imports is also increasing. According to statistics, the total amount of domestic crude oil and imported crude oil in 2004 was about 290 million tons. , Of which 120 million tons of imported crude oil alone. However, the problem of the volatilization of oil and gas during the transportation and storage of gasoline has not attracted our attention. According to CARB (California Air Resources Association) inspections of gas stations (without oil gas recovery devices), for every 1,000 gallons (2952kg) of gasoline sold, 0.84 pounds (0...

Problems solved by technology

[0003] Domestic data also show that in 2003, the country consumed 50 million tons of gasoline, and at least 280 million cubic meters (340,000 tons) of oil and gas were discharged during operation and sales, and the economic loss caused by oil and gas volatilization was as high as 1.3 billion yuan; and according to incomplete statistics, in 2004 The economic loss caused by volatilization of oil and gas in my country is as high as 2 billion RMB in 2019. Volatilization of oil and gas will produce a large amount of oil and gas with high saturation concentration. If it touches Mars or static electricity, it will explode, which has brought great harm to the oil tank area and gas stations. security risks

Now some gas stations in the downtown area have begun to install fuel guns with gas recovery devices. Although the problem of volatilization of oil and gas generated at the refueling end of the car has been solved, since the recovered oil and gas have not been recycled, most of them are discharged through the breathing cap. Therefore, the safety hazard has not been fundamentally eliminated.
