Problems solved by technology
This detector has the following disadvantages: (1) the main control of the detector is an 8-bit ordinary single-chip microcomputer, and the measurement accuracy of the system is not high; (2) multiple testing equipment must be equipped when performing gas station index acceptance testing, which is not easy to carry and Handling also increases the complexity of equipment operation; (3) It is necessary to manually input the refueling amount, and the gas-liquid ratio data cannot be stored in real time, which makes it difficult for further analysis of the oil and gas recovery system

Embodiment 1
[0036] The gas-liquid ratio refers to the ratio of the measured gas volume to the gasoline volume measured by the fuel dispenser at the same time. Through the detection of the gas-liquid ratio, the recovery effect of the oil gas recovery system can be understood. Such as figure 1 As shown, the present embodiment is a portable gas-liquid ratio dynamic monitoring system for oil and gas recovery, including a control module, an oil and gas recovery device, an oil flow meter, a gas flow meter, a display device and a liquid storage tank for testing, wherein the control module is developed using STM32 plate. The oil and gas recovery device includes an oil and gas recovery vacuum pump and an adapter for the gas-liquid ratio. The oil flow meter is the flow meter that comes with the fuel dispenser, specifically including a volumetric flow converter and an encoder, and the encoder is connected to the control module.

The invention discloses a portable oil gas recovery gas-liquid ratio dynamic monitoring system and a monitoring method. The monitoring system comprises a control module, an oil gas recovery device, an oil flow meter, a gas flow meter, a display device and a liquid storage tank for testing. The oil flow meter is connected with the control module. One end of the oil gas recovery device is connected with a gasoline station underground oil storage tank, and the other end of the oil gas recovery device is connected with the oil storage tank for testing. The gas flow meter is disposed between the oil gas recovery device and the oil storage tank for testing. The gas flow meter and the control module are in communication through an RS485 interface. The display device is connected with the control module and used for displaying current refueling flow speed, oil gas recovery flow speed, refueling amount, oil gas amount, the gas-liquid ratio, the flow speed ratio and other parameters in real time. According to the method, gasoline volume in an oil tank during dynamic monitoring and oil gas volume collected during refueling can be simultaneously collected in real time. People do not need to manually input the refueling amount and oil gas amount, finally, a result is displayed on the display device, and the gas-liquid ratio is dynamically monitored.
Description
technical field [0001] The invention relates to the research field of gas station oil gas recovery system, in particular to a portable oil gas recovery gas-liquid ratio dynamic monitoring system and monitoring method. Background technique [0002] Domestic oil and gas pollution control is late, but as gas stations begin to popularize and install secondary oil and gas recovery equipment, testing its gas-liquid ratio is one of the key items to check whether the oil and gas recovery equipment meets the requirements. The national gas station oil and gas emission standard (GB20952-2007) stipulates that the gas-liquid ratio of various gas station oil and gas recovery systems should be within the range of greater than or equal to 1.0 and less than or equal to 1.2. The gas-liquid ratio in the oil gas recovery system refers to the ratio of the volume of oil gas collected during refueling to the volume of gasoline added to the tank at the same time, namely: [0003] [0004] At pr...
