Problems solved by technology

The calibration process requires refueling, tank return, and refueling personnel’s records and accounts. The procedure is cumbersome, time-consuming and labor-intensive
In addition, the oil return container of the current gas station usually only has an open metering barrel. The oil vapor recovery system cannot be sealed when refueling in the barrel, and a large amount of organic gas will be volatilized, causing environmental pollution, endangering the health of the staff, and increasing the danger of the calibration process.

Description

technical field [0001] The invention belongs to the technical field of gas station environmental protection, and in particular relates to an electronic gas-liquid ratio adjustment dry calibration device and method. Background technique [0002] In order to reduce oil and gas emissions during refueling at gas stations, the State Environmental Protection Administration issued and implemented GB20952 "Emission Standards for Air Pollutants at Gas Stations" in 2007, which stipulates that the gas-liquid ratio of refueling oil and gas recovery systems should be within the range of 1-1.2 to ensure The operation effect of oil vapor recovery system. [0003] At present, there are mainly three kinds of gas-liquid ratio adjustment methods on the market, one is traditional mechanical gas-liquid ratio adjustment, the other is open-loop electronic gas-liquid ratio adjustment, and the third is closed-loop electronic gas-liquid ratio adjustment: mechanical gas-liquid ratio adjustment Ratio ...
