Lightning protection and grounding design method and system for soil-covered vertical oil tank

Abstract

The invention relates to the technical field of lightning protection and grounding of petroleum storage tanks, in particular to a lightning protection and grounding design method and system for a soil-covered vertical oil tank. The method comprises the following steps: preliminarily determining the arrangement form and size of a lightning protection grounding facility based on a grounding resistance calculation formula by comprehensively considering tank field environment equipment factors, simulating an actual engineering scene, and further designing and adjusting an arrangement scheme in combination with simulation software to obtain an optimal arrangement scheme meeting the lightning protection grounding requirement of the earthing vertical oil tank; burying the annular conductor with the outer contour matched with the tank body in the overburden layer to be matched with the lightning protection grid to form reliable lightning protection, in which the structure is compact, and the material cost is saved. By connecting the top overburden layer lightning protection system, the tank chamber internal grounding system, the underground pipe trench internal grounding system between the oil tanks and the tank area grounding system, the whole tank area is subjected to complete lightning protection and grounding protection, the project land acquisition area is saved, and maintenance is convenient, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of lightning protection and grounding of petroleum storage tanks, in particular to a design method and system for lightning protection and grounding of a soil-covered vertical oil tank. Background technique [0002] Because soil-covered oil tanks can reduce the evaporation loss of oil storage, delay oil deterioration, and at the same time have certain air concealment effects and safety protection capabilities, more and more reserve oil depots begin to adopt the form of soil-covered oil tanks. However, accidents of explosion and fire of oil tanks caused by lightning occur from time to time, which bring serious losses to oil depots. Therefore, doing a good job in lightning protection and grounding of soil-covered oil tanks is an important task to ensure the safe operation of oil tanks. [0003] Ordinary ground oil storage metal tanks can be directly used as lightning protection objects because the thickness o...

Problems solved by technology

However, the vertical metal oil storage tank placed in the reinforced concrete tank room cannot use its tank roof as a lightning protection object. This requires comprehensive consideration of the lightning protection and grounding of the oil tank area according to the engineering requirements, especially how to set up the lightning protection Thunder system is particularly important

[0004] In the existing technology, there are few studies on the lightning protection and grounding system of soil-covered vertical oil tanks, and the practices at home and abroad are inconsistent, and the factors considered in the design and implementation are not comprehensive enough to meet the actual engineering safety requirements.
