Why vigorously promote and popularize the use of oil and gas recovery devices? Photochemical pollution caused by volatile organic compounds (VOC) has become an important environmental problem faced by some cities in my country. Oil evaporation from urban gas stations and oil from oil storage depots are an important source of VOC emissions. In the uncontrolled situation, this part of the emissions from gas station oil evaporation will have more and more serious impact on the environment and economy. Therefore, it is of great significance to go deep into the pollution control of oil and gas recovery in gas stations and oil storage depots in our country, and select the oil and gas recovery device suitable for use in our country.
Principle of oil and gas recovery device: The function of the oil and gas recovery system of the oil tanker is to realize the fully enclosed gas recovery during the loading and unloading of the oil tanker, and limit the emission of oil and gas into the atmosphere. That is, the oil pipeline and the oil and gas recovery pipe of the oil tanker and the oil storage tank are connected to form a closed oil and gas recovery pipeline. While the oil tanker is unloading oil through the oil unloading pipeline, the oil and gas in the oil tank of the gas station is returned to the oil tanker through the return gas pipeline. The oil tanker takes the oil and gas back to the oil depot for processing to achieve the purpose of oil and gas recovery. When the oil is input, the volatilization and dissipation of oil and gas will increase due to the fluctuation of the liquid level. Therefore, the oil injection pipe must go deep below the oil surface to reduce the liquid level disturbance. The opening of the oil and gas recovery pipe is equipped with a special opening function device. When the oil and gas recovery line of the oil tanker is correctly connected to the oil tank, the recovery port will be opened, and the exhaust pipe will be closed at the same time, so that the oil and gas in the oil tank can be completely returned to the oil from the recovery port. Inside the tanker.
