Description
Technical Field
The invention relates to a pipeline for inhibiting liquid static accumulation.
Background
When liquid flows in a pipeline, a large amount of static electricity can be generated due to friction with the pipe wall, static electricity can be accumulated to generate static electricity risks, and if the static electricity explosion risks exist in the process of pipe transportation of a gas station in an oil depot, huge safety pressure is brought to enterprises.
Research on the generation of static electricity in oil depots and safety precautions (proceedings of the university of ziqihal (natural science edition) 2011-7) when petroleum products are in close contact with the pipe wall and the tank wall, an electric double layer is generated on the solid-liquid interface. The diffusion charge layer is washed away when the liquid flows and flows along with the liquid, so that positive and negative charges are separated to enable the pipe wall and the oil product to be charged with static electricity, and the charge quantity of the diffusion charge layer is related to the flow velocity of the liquid, the material and the roughness of the pipe, the resistivity of the fluid and the like.
