Embodiment 1

[0014] Such as figure 1 , figure 2 As shown, a floating roof storage tank with multiple lightning strike protection includes a tank body and a floating roof, and a lightning strike zone is arranged above the floating roof.

[0015] The lightning-termination zone is welded to the tank body, and the intersections between the lightning-termination zones are reliably welded.

[0016] The lightning-terminating belt is made of hot-dip galvanized steel strand or copper strand, and the cross-sectional area is not less than 50mm 2 .

[0017] The grid formed by the lightning zone should not be larger than 10m×10m or 12m×8m.

[0018] The lightning belt is set above the floating roof and is electrically connected to the tank body, which realizes direct lightning protection for the floating roof and prevents lightning from directly hitting the floating roof of the storage tank with the outer floating roof.

Abstract

The invention relates to a multi-lightning protection floating roof storage tank, and mainly aims at solving the problem that complete lightning protection cannot be achieved in the prior art. The multi-lightning protection floating roof storage tank comprises a tank body, a floating roof, air-termination strips and a shielding net, wherein the air-termination strips are arranged above the floating roof and are welded with the tank body; intersection points among the air-termination strips are reliably welded; galvanized steel stranded wires or copper stranded wires are adopted by the air-termination strips; the sectional area is not less than 50mm<2>; meshes formed by the air-termination strips are not greater than 10m*10m or 12m*8m; the shielding net is arranged between the air-termination strips and the floating roof; and the distances from the shielding net to the air-termination strips are greater than 10cm; the shielding net is welded with the tank body along the periphery of the tank wall; and the shielding meshes are not greater than 80mm*80mm. According to the technical scheme, the problem is relatively well solved; and the multi-lightning protection floating roof storage tank can be applied to lightning protection of the floating roof storage tank.

Description

technical field [0001] The invention relates to a floating roof storage tank with multiple lightning strike protection. Background technique [0002] Petroleum is an important strategic material, which is related to the development of the national economy and the stability of the society. At present, the country has established a number of large-scale national oil reserve bases, and oil tank farms are mostly built in areas prone to lightning disasters such as rivers and coasts, where storage tanks are vulnerable to lightning strikes and fires. In recent years, there have been many fire accidents of floating roof storage tanks caused by lightning strikes in crude oil depots in China. This is related to the large diameter of the floating roof of the storage tank and the obvious increase in the probability of direct lightning hitting the floating roof. At the same time, the lightning induction on the floating roof caused lightning sparks. Also more prominent. [0003] In orde...
