Embodiment 1

[0016] A pipe that inhibits the electrostatic build-up of liquids such as figure 1 As shown, including the pipe wall and the pipe main body, the pipe wall is made of two materials: the pipe wall of material A and the pipe wall of material B, which are alternately spliced, and the number of alternations is 2 times, that is, the pipe wall consists of two materials A and two There is a material B, and material A, material B are opposite in polarity to the liquid friction. The tube wall is made of two kinds of materials, and the difference in electric quantity between the frictional electrification of the liquid and the liquid is within 30%. The ratio of the total curvature of the material A pipe wall to the total curvature of the material B pipe wall is inversely proportional to the electrostatic charging characteristics of the material.

[0017] The friction between the liquid and the pipe wall of different materials will generate charges of different polarities to neutralize e...

Embodiment 2

[0019] A pipe that inhibits the electrostatic build-up of liquids such as figure 1 As shown, including the pipe wall and the pipe main body, the pipe wall is made of three materials: the pipe wall of material A, the pipe wall of material B and the pipe wall of material C, which are spliced ​​alternately, and the number of alternations is 2 times, that is, the pipe wall consists of three There are one material A, three material B, and three material C, and material A, material B, and material C are opposite in polarity to the frictional electrification of the liquid. The pipe wall is made of three kinds of materials, and the difference in electric quantity between the frictional electrification of the liquid and the liquid is within 30%. or the same. The ratio of the total curvature of the material A pipe wall to the total curvature of the material B pipe wall is inversely proportional to the electrostatic charging characteristics of the material. The friction between the liq...

Abstract

The invention relates to a pipeline restraining liquid static electricity accumulation. The problems that in the prior art, static electricity is liable to accumulate in a pipeline, and consequently safety is poor are mainly solved. The pipeline restraining liquid static electricity accumulation comprises a pipe wall and a pipeline main body. The pipe wall is made of at least two materials, the above problems are well solved with the technical scheme of opposite polarities of friction electrification of all the materials and liquid, and liquid static electricity can be restrained from accumulating in the pipeline.

Description

technical field [0001] The present invention relates to a pipeline that inhibits the electrostatic accumulation of liquids. Background technique [0002] When the liquid flows in the pipeline, friction with the pipe wall will generate a large amount of static electricity, and the accumulation of static electricity will cause static electricity risks. For example, there is a risk of static deflagration during pipeline transportation at oil depots and gas stations, which brings huge safety pressure to enterprises. [0003] "Research on the Generation of Static Electricity in Oil Depots and Safety Precautions" (Journal of Qiqihar University (Natural Science Edition) 2011-7) When petroleum products are in close contact with the walls of pipelines and tanks, a galvanic layer is generated on the solid-liquid interface. The diffused charge layer is washed down when the liquid flows and flows with the liquid, which causes the separation of positive and negative charges and makes the...
