Problems solved by technology

Although the effect of this process reaches the national standard, since the condensing device and the adsorption device are integrated in the gas station, it occupies a large area and requires a large investment, and the method consumes a lot of electricity during the condensation process, and the recovered oil and gas are far less than the consumed electricity. , economic and environmental benefits are greatly reduced

Embodiment Construction

[0025] The preferred embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] A method for recovering oil and gas at a gas station, comprising the steps in sequence:

[0027] a) Oil and gas collection, using the oil and gas collection method in the prior art;

[0028] b) Oil gas adsorption: the oil gas collected in step a) is adsorbed by the adsorbent in the adsorption device, and the unadsorbed gas is discharged into the atmosphere;

[0029] c) Oil and gas regeneration: When the adsorbent in step b) needs to be regenerated, the mobile regeneration device is sealed and connected to the adsorption device, and the vacuum equipment in the mobile regeneration device desorbs the adsorbent, and the desorbed high-concentration oil gas enters the mobile regeneration device The condensing unit connected to the vacuum equipment condenses below -35°C, the uncondensed oil and gas are adsorbed by the adsorption unit in th...

Abstract

The invention belongs to the technical field of energy conservation and environment protection and particularly relates to an oil and gas recovering method and an oil and gas recovering device for a gasoline station. The oil and gas recovering device adopted by the invention comprises an oil and gas absorption device and a regenerating device, wherein the absorption device is fixedly arranged in the gasoline station for absorbing the oil and gas collected in the gasoline station. The oil and gas recovering device is characterized in that: the regenerating device comprises vacuum equipment mounted on a mobile transport vehicle and a condensing unit connected with the vacuum equipment; and a movable joint on the front end of the vacuum equipment is matched with a movable joint holder arranged on the absorption device to realize the sealed connection of the absorption device and the regeneration device. In the invention, by adopting the oil and gas absorption device and the regenerating device, the investment and energy consumption of the gasoline station can be reduced effectively, and the economic benefit and safety of the gasoline station can be improved effectively.

Description

technical field [0001] The invention belongs to the technical field of energy saving and environmental protection, and in particular relates to an oil gas recovery method and device used in gas stations. Background technique [0002] With the rapid growth of the number of cars, the number of gas stations has also increased rapidly. Gasoline is a volatile petroleum product. During the process of receiving gasoline at the gas station and refueling the car, a large amount of oil and gas will be released into the atmosphere, which wastes precious resources, pollutes the environment, and brings safety to the gas station. Hidden danger. Therefore, the recovery and reuse of oil and gas is of great significance. China's national standards "Emission Standards of Air Pollutants for Oil Storage Depots" (GB20950-2007) and "Code for Design and Construction of Automobile Refueling and Gas Stations" (GB50156-2002) have made oil and gas recovery Regulation. [0003] Oil and gas recovery ...
