Embodiment 1
[0020] Such as figure 1 As shown, the online monitoring system for secondary oil and gas recovery in gas stations includes multiple gas flowmeters, a pressure transmitter, multiple data collectors and an embedded monitoring machine. The gas flowmeter used in the present invention is a Roots flowmeter.
[0021] The gas flow meter is connected in series to the gas return pipeline of the oil and gas recovery refueling gun, and one gas flow meter is installed for each refueling gun, or one gas flow meter is shared by every two refueling guns; Install on the return gas main pipe of the nearest tanker or on the exhaust pipe of the tank, and install one pressure transmitter in the entire gas station; the data collector is installed inside the tanker, and one data collector is installed for each tanker For the collector, a fuel dispenser with more than 4 gasoline refueling guns needs to install an additional data collector; the embedded monitoring machine is installed in the gas stat...

The invention relates to an on-line monitoring system for secondary oil and gas recovery at a gas station, which mainly solves the problems of large space occupation, high cost and complicated construction and installation in the prior art. The present invention adopts an online monitoring system for secondary oil and gas recovery at a gas station, including at least one gas flowmeter, at least one pressure transmitter, at least one data collector and at least one embedded monitoring machine, the gas flowmeter It is connected in series to the gas return pipeline of the oil gas recovery refueling gun, the pressure transmitter is connected to the gas return main pipe of the tanker or installed on the exhaust pipe of the oil tank, the data collector is installed inside each tanker, and the embedded monitoring The technical scheme that the machine is installed in the gas station room solves the above problems well, and can be used in the on-line monitoring of the secondary oil and gas recovery in the gas station.
Description
technical field [0001] The invention relates to an on-line monitoring system for secondary oil gas recovery at a gas station. technical background [0002] With the continuous improvement of my country's economic development level, environmental protection issues have attracted more and more attention from the government and ordinary people. In order to reduce and control the air pollution caused by oil and gas emitted by gas stations, the State Environmental Protection Administration issued and implemented GB20952-2007 "Emission Standards of Air Pollutants for Gas Stations" in 2007, requiring gas stations in all regions to carry out secondary oil and gas recovery transformation before 2015 , and gas stations with an annual sales volume of more than 8,000 tons of gasoline and gas stations with an annual sales volume of more than 5,000 tons in cities where the ozone concentration exceeds the standard should install an online monitoring system. [0003] The secondary oil and ...
