Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] like figure 1 As shown, the graphene adsorption tertiary oil gas recovery device of the present invention includes a gasoline storage tank 1, an adsorption pump 2, a condenser 3 and a graphene adsorption tank. The gasoline storage tank 1 is a container for storing gasoline, and the inside contains saturated or nearly saturated oil gas. The inlet of the adsorption pump 2 is connected with the gasoline storage tank 1 , the outlet of the adsorption pump 2 is connected with the inlet of the condenser 3 , and the adsorption pump 2 is used to send oil gas and air into the condenser 3 . The adsorption pump 2 can be adjusted manually or automatically. For example, a pressure measuring device, such as a micro-pressure transmitter 9, is provided between the inlet of the adsorption pump 2 and the gasoline storage tank 1 . The micro-pressure transmitter 9 is used to detect the...

Abstract

The invention discloses a graphene adsorption tertiary oil gas recovery device, relates to the field of oil gas recovery, and solves the problem that an existing oil gas recovery device cannot realize complete recovery of oil gas. According to the technical scheme, the graphene adsorption tertiary oil gas recovery device comprises a gasoline storage tank, an adsorption pump, a condenser and a graphene adsorption tank, an inlet of the adsorption pump is connected with the gasoline storage tank, an outlet of the adsorption pump is connected with the condenser, the condenser is provided with a gasoline outlet and an oil gas outlet, the gasoline outlet is connected with the gasoline storage tank, the oil gas outlet is connected with a bottom inlet / outlet of the graphene adsorption tank, an oil return pipeline is arranged or formed between the bottom inlet / outlet and the gasoline storage tank, an exhaust port of the graphene adsorption tank is connected with an exhaust pipe, the exhaust pipe is provided with an exhaust valve and an oil gas concentration detector, the tail end of the exhaust pipe is an exhaust end, and the graphene adsorption tank is further provided with a desorption system. The graphene adsorption tertiary oil gas recovery device is used for recovering volatile components in the gasoline storage tank and enabling the recovered gasoline to flow back into the gasoline storage tank.

Description

technical field [0001] The invention relates to the field of oil gas recovery, in particular to a device for recovering components volatilized from gasoline storage tanks. Background technique [0002] Gasoline contains a large amount of light hydrocarbon components, and some liquid hydrocarbon components will inevitably volatilize during storage, sales and application, resulting in oil loss. Oil and gas volatilization causes energy waste, environmental pollution and safety hazards, so measures need to be taken for oil and gas recovery. [0003] The authorized announcement number is the patent of CN 211936242 U, which discloses a tertiary oil and gas recovery device for gas stations, which mainly consists of three parts: adsorption, regeneration and control system. The adsorption part is used to absorb oil and gas, the regeneration part is used to desorb the oil and gas in the activated carbon bed, and the oil and gas are cooled by the air cooler and sent to the gasoline ta...
