Problems solved by technology

In practical applications, due to the influence of the accuracy of the liquid level gauge, other environments, and on-site factors, it is often impossible to detect the leakage and small amount of leakage of the oil storage tank in a timely and accurate manner.
Moreover, the common method for the detection of oil storage tank leakage does not have real-time online monitoring and alarm functions, and cannot prevent oil leakage.

Abstract

The invention discloses a soil leakage monitoring technology of an oil storage tank using a magnetic tracer, which belongs to the technical field of soil penetration detection of an oil storage tank. The oil in the oil storage tank contains a magnetic tracer, which consists of a core layer and a The composition of the shell layer; the material constituting the core layer is magnetic Fe 3 o 4 Nanoparticles; the material constituting the shell is a carbon layer, the carbon layer is a polysaccharide layer obtained by hydrothermal reaction of glucose, and the surface of the carbon layer is grafted with glycidyl methacrylate and abietic acid. The magnetic tracer is not easy to be weakened due to oxidation or acid and alkali corrosion, has a low oil contact angle, can be stably dispersed in the oil phase for a long time, and has strong magnetic responsiveness, which is easy to be detected by a magnetic sensor . The above monitoring technology includes: using a monitoring device including a detection module to collect the level signal corresponding to the magnetic field signal generated by the magnetic tracer, and monitoring the soil leakage of the oil storage tank. This monitoring method has high sensitivity, high positioning accuracy, environmental protection, and monitoring wide range.

Description

technical field [0001] The invention belongs to the technical field of soil infiltration detection of oil storage tanks, and in particular relates to a soil leakage monitoring technology of oil storage tanks using a magnetic tracer. Background technique [0002] Oil is a more serious pollutant. At present, most domestic gas stations use buried oil storage tanks for oil storage, and the nature of oil itself is relatively complex, with strong corrosiveness, and there is a serious problem of corrosion of oil storage tanks; and buried oil storage tanks Tanks buried underground for a long time will leak under the action of geological disasters and natural corrosion with the increase of service life. If the leakage is not detected in time, it will not only cause hidden safety hazards and economic losses, but also pollute the soil and groundwater, causing serious harm to the environment. At present, the leakage detection of buried oil storage tanks mostly adopts indirect measurem...
