Novel oil gas recovery control system of gas station

Abstract

The invention discloses a novel oil gas recovery control system of a gas station. The system comprises a flow metering pulse sensor, a controller, a recovery motor, a recovery oil pump and a gas flow regulating valve, wherein the flow metering pulse sensor is in signal connection with a flow meter on an oil filling pipeline; the flow metering pulse sensor is in signal connection with the controller, the recovery motor and the recovery oil pump sequentially; and the gas flow regulating valve is connected with the recovery oil pump and an oil tank sequentially. The oil gas recovery control system of the gas station is characterized by also comprising a temperature sensor and a gas flow regulating valve control device, wherein the temperature sensor is arranged on the oil filling pipeline; the gas flow regulating valve control device is in signal connection with the temperature sensor; and the gas flow regulating valve control device is in signal connection with the gas flow regulating valve and controls opening of the gas flow regulating valve. In the system, the proportion of oil gas recovery is controlled by a flow signal and a temperature signal simultaneously, regulation and control are more accurate, and frequency-conversion self-adaptive control of the oil gas recovery can be realized. The system is particularly in accordance with the practical condition of the gas station of China.

Description

technical field [0001] The invention relates to an oil gas recovery system, in particular to an oil gas recovery control system suitable for gas stations in my country. Background technique [0002] Fuel dispenser is a fuel sales terminal equipment. Ordinary fuel tanker hydraulic control system is generally composed of motor, displacement pump, oil-gas separator, flow measurement converter, encoder, counter, indicating device, solenoid valve, oil sight, oil gun, control board and other main components. Complete liquid transport and measurement system. [0003] Gas station oil and gas recovery technology, currently there are primary, secondary, and tertiary recovery. One-time recovery refers to the recovery of oil and gas discharged from the oil depot at the same time when the tanker unloads the oil to the oil depot of the gas station. Secondary recovery refers to the recovery of the oil and gas discharged from the fuel tank at the same time when the fuel tank is refueled ...

AI Technical Summary

Problems solved by technology

[0008] The above recovery systems have the following disadvantages: Since the saturated vapor pressure of gasoline and other gasification media increases significantly with the increase of temperature, gasoline and other gasification media are more likely to volatilize at high temperatures

Therefore, the recovery system of the above-mentioned manufacturers using a fixed ratio recovery method is not suitable for the actual situation in our country
