Abstract

The invention discloses a zero-emission tertiary oil gas recovery system and method for a gas station. The zero-emission tertiary oil gas recovery system comprises an oiling machine, wherein the oiling machine communicates with a gasoline tank; the oiling machine is equipped with an intelligent controller; an oiling pump is arranged in the oiling machine; the oiling pump communicates with an oiling flow meter; the oiling flow meter communicates with an oil gas separating valve; the oil gas separating valve communicates with an oiling gun; the oil gas separating valve further communicates witha gas extracting vacuum pump; the gas extracting vacuum pump communicates with a gas extracting flow meter; the gas extracting flow meter and the oiling pump communicate with the gasoline tank; the oiling pump, the oiling flow meter, the gas extracting vacuum pump and the gas extracting flow meter are electrically connected with the intelligent controller; the gasoline tank is equipped with a pressure transmitter; and the pressure transmitter is electrically connected with the intelligent controller. According to the scheme adopted by the invention, tertiary oil gas automatic recovery in an automobile oiling process of the gas station can be realized, and zero emission, zero loss and zero maintenance of gasoline oil gas in the oiling process of the gas station also can be realized.

Description

technical field [0001] The invention relates to the field of air pollution VOCs treatment for environmental protection, in particular to a zero-emission tertiary oil and gas recovery system and method for gas stations. Background technique [0002] When the fuel dispenser at the gas station is filling the car with gasoline, the fuel tank port of the car will discharge the same volume of saturated gasoline gas as the gasoline liquid flows in. For example, an annual sales volume of 3000m 3 Gasoline gas stations emit 600-800m3 of saturated gasoline gas into the atmosphere every year 3 . There are about 100,000 gas stations in my country, of which the sales volume of gasoline is about 1 million m 3 , about 160,000 m3 of saturated gasoline gas is discharged into the atmosphere through the gas station during refueling 3 Therefore, gasoline volatile gas is an important pollution source of atmospheric environmental pollution. my country's environmental protection laws and regulat...
