How to reasonably control the static electricity generated by SF double-layer tank

In the process of using double-layer oil tanks, we must pay attention to the prevention of safety measures (referring to the solution to the problem). Regarding the pressure vessel in the process of using it, we should correctly avoid the generation of static electricity. Oil is a product with certain potential safety hazards. In the process of using, you must pay attention to prevent the appearance of static electricity. It is flammable, explosive, easy to generate static electricity and has a certain toxic effect on the human body. How to correctly avoid the occurrence of static electricity in the oil tank during the process?

All oil tanks, pipelines, and loading and unloading equipment used to store and transfer oil products must have a good grounding device. Static electricity (a static charge) should be introduced into the ground in time, and the electrostatic grounding device technology should be inspected frequently Condition and test ground resistance. The machinery and equipment of the skid-mounted refueling device and gas station roughly includes six categories: storage equipment, transmission equipment, refueling equipment, power equipment, transportation equipment and fire safety equipment. The grounding resistance of the oil tank in the oil depot should not be greater than 10Ω (including static electricity and safety grounding). The grounding electrode of the double-layer oil tank is calculated according to the circumference of the oil tank, one set every 18m, and the grounding electrode of the horizontal oil tank should be no less than two sets.
　　
When filling oil tanks, tank cars, and railway tank cars, the oil pipeline must be inserted below the oil level or close to the bottom of the pressure vessel to reduce the impact of the oil and the friction with the air.
In the season when the air is particularly dry and the temperature is high, you should pay special attention to the inspection of the grounding equipment of the double-layer oil tank, slow down appropriately, and if necessary, conduct static electricity (a static charge) around the ground electrode at the work site Watering. At the beginning of oil delivery, oil filling and three-quarters to the end of oil filling into the container, electrostatic discharge accidents (a kind of static charge) are prone to occur. At this time, the flow rate should be controlled within 1m/s.
　　
When the ship is loading oil, the outlet of the fueling pipe must be kept in metal contact with the oil inlet of the tanker. The classification of gas station oil tanks is mainly divided into two categories according to material and structure. At present, most of the oil tanks used in gas stations for automobiles and diesel are horizontal double-layer steel oil tanks. As for non-metal pressure vessels, because of their It has many shortcomings such as leakage, so it is not used in gas stations. Therefore, the specification stipulates that the oil tank for refueling should be a horizontal double-layer oil tank. Gas station tanks are containers for storing crude oil or other petroleum products. Used in oil refineries, oil fields, oil depots and other industries. The tank farm consists of multiple tanks. Each tank area generally stores one type of oil.
　　
It is strictly forbidden to pour light fuel oil into plastic (structure: synthetic resin, plasticizer, stabilizer, pigment) barrels in the oil depot, and it is prohibited to use plastic containers to invert the light fuel oil in the area that affects the safety of the oil depot.
