Background
Along with the development of economic level, the living standard of people is improved day by day, people's demand to good environment is promoting, and filling station has the condition of oil gas emission in daily operation, influences the air quality. How to reduce the emission of organic matters to the atmosphere and improve the air quality is a big topic of the current society for environmental protection. How to keep the oil gas recovery system operating rationally reduces the pollution of organic emission to atmosphere, reduces the health influence to on-the-spot staff and customer, reduces the operation loss, promotes the enterprise image, is the target that everybody pursues jointly.
The monitoring of three indexes of the existing oil gas recovery system adopts 2 modes:
1. according to the legal requirements, the national regulation enterprises hire third parties with qualification testing, the oil gas recovery system is detected once every year, a detection report is issued, and monitored equipment meets the monitoring requirements. The disadvantages of this approach: firstly, the business stopping detection influences the operation, secondly, the charge is high, and thirdly, the detection time span is long, thereby influencing the daily equipment management of the gas station.
2. Foreign early technologies are still used, and an online monitoring method is adopted, wherein the patent numbers are as follows: CN201310488264, patent name: the invention discloses an on-line monitoring system for secondary oil gas recovery of a gas station, which is characterized in that an explosion-proof gas flow meter is arranged on an oil gas loop of each gasoline gun, the oil gas recovery gas-liquid ratio of each fueling transaction is detected, recorded and sent, and the abnormality is immediately known. The specific structure is shown in fig. 1 to fig. 3, a gas station generally has 4-6 fuel dispensers, and if there are 4 fuel dispensers as shown in fig. 1, each fuel dispenser has 6 fuel guns, as shown in fig. 2, 3 fuel guns are respectively arranged at the front and back, only 3 fuel guns are shown at the front in fig. 2, and 24 fuel guns are arranged in one gas station, the price of the current fuel dispenser is about 7-10 ten thousand, but for the supervision of government departments, each fuel gun must be provided with an explosion-proof gas flow meter to detect gas recovery data, while the explosion-proof gas flow meter on the market is generally about 14000 yuan, 6 explosion-proof gas flow meters are equivalent to the price of one fuel dispenser, and the fuel dispenser needs to be disassembled to install 6 explosion-proof gas flow meters in the fuel dispenser, the detection signal of the explosion-proof gas flow meter is connected to the control circuit board of the fuel dispenser, so that the fuel data and the data of the recovered gas are sent to the gas station background computer to calculate the gas-liquid ratio, whether the oil gun meets the supervision requirement or not is known through detecting the gas-liquid ratio. The specific structure is shown in figure 3. The disadvantages of this approach: firstly, excessive monitoring, the oil gas recovery system equipment is ripe stable, key part: the vacuum pump and the gas-liquid ratio regulating valve have longer service life, the indexes in the life cycle of the equipment are stable and controllable, and each transaction does not need to be monitored. Secondly, excessive installation of equipment facilities causes resource waste; each oil gun is provided with an explosion-proof gas flow meter, so that the cost is high, the installation cost is higher than that of an oiling machine, a monitoring system does not produce any benefit, and enterprises cannot bear the cost. Thirdly, the fixedly installed gas flowmeter adopts more electronic types, so that electronic drift is easy to generate, the metering is inaccurate after a certain time, the gas flowmeter is difficult to disassemble, assemble and inspect, the requirements of the gas flowmeter as a metering device are not met, and the gas flowmeter should not be used as an administrative supervision basis.
