Embodiment 1

[0029] like figure 1 As shown, the device is composed of a switching power supply 9, an alternating signal generating circuit 10, a ferrite ring 3 and a metal pipe 4, wherein 1 is a metal cable, 2 is a plastic bolt for fixing, 5 is a free electron indication, and 6 is a Schematic illustration of the magnetic field inside a metal pipe.

Embodiment 2

[0031] In actual operation, we can change the frequency of the alternating signal according to the material and thickness of the pipe wall, thereby changing the skin depth and improving the anticorrosion effect. The skin depth is inversely proportional to the frequency. According to theoretical calculations, when the frequency of the alternating signal is between 20KHz and 1000KHz, the anti-corrosion effect of the metal pipeline is better.

[0032] As shown in Figure 2, the circle 7 represents the cross-section of the metal wire, and the small cross sign represents the flow direction of the current in the wire at a certain moment, and the direction 8 of the magnetic field around the wire can be judged by the "right-hand rule", as Figure 2a situation shown. On this basis, consider two wires that are so close together that the field lines around them are twisted, taking on the shape of a double loop, but still running in a clockwise direction. Add some extra wires and the fiel...

Description

technical field [0001] The invention belongs to the field of metal anti-corrosion, and more specifically relates to a device for realizing anti-corrosion on the surface of metal pipelines by using electromagnetic fields / waves. Background technique [0002] Corrosion is a major problem that has plagued industrial production for a long time. Taking the petrochemical industry as an example, the annual losses caused by corrosion in the petrochemical industry are far greater than those caused by natural disasters such as floods, fires, and earthquakes. Among them, corrosion of metal pipes accounts for A large proportion. With technological progress and industrial requirements, various new pipeline manufacturing technologies have developed rapidly, and various anti-corrosion methods have emerged as the times require. [0003] The commonly used metal anti-corrosion methods mainly include the following types. The first is to add anti-corrosion agent in the metal pipeline, which ca...
