▎ 摘　　要

NOVELTY - The device has an adsorption pump (2) whose inlet connected with a gasoline storage tank (1). An outlet of the gas absorption pump is connected to an inlet of a condenser (3). The condenser is provided with a fuel outlet (31) and an oil gas outlet (32). A drain valve (33) is provided at the fuel outlet and connected with the fuel tank. The oil gas outlets are connected to the bottom inlet and the bottom outlet of a graphene adsorbent tank. An oil return pipeline flowing to the fuel storage tank is formed at the bottom of the graphene adsorption tank and the fuel storing tank. An exhaust pipe is provided on the exhaust port of the graphene adsorption tank. A gas concentration detector (6) is arranged at the exhaust pipe. The tail end of the exhaust pipeline is an outer discharge end. A desorption system is configured in the graphene adsorption tank. The graphene adsorption tank is further configured with a desorption system. USE - Graphene adsorption tertiary oil gas recycling device for recycling volatile component volatilized from a gasoline storage tank in a gas station. ADVANTAGE - The device: graphene adsorption tertiary oil gas recycling device is used for recycling the volatile component in the gasoline storage tank, the recycled gasoline is re-flowed to the petrol storage tank. The mixed gas formed by oil gas and air is sent to the condenser through the adsorbent pump, most of the oil gas is collected in the condenser after being liquefied, and it flows into the gas storage tank through the drain valve. The exhaust gas of the graphene adsorbant tank does not contain volatile organic compound, can be directly discharged into the atmosphere, and realizes the complete recovery of the gas. DESCRIPTION OF DRAWING(S) - Gasoline storage tank (1) Adsorption pump (2) Condenser (3) Oil gas outlet (32) Drain valve (33)
