Explosion-proof structure and explosion-proof wall for offshore platform

Abstract

The invention discloses an explosion-proof structure. The structure comprises a wave reduction assembly and a wave absorbing assembly, wherein the wave reduction assembly can reduce shock waves generated by explosion, the wave absorbing assembly further absorbs the shock waves, the wave reduction assembly comprises a perforated bent plate and a connecting plate which are sequentially distributed along an explosion facing surface, the bent plate has a certain reflection effect and changes the entering angle of the shock waves, and the connecting plate is connected with the bent plate and the wave absorbing assembly to form a wave reduction cavity. After the shock waves enter the wave reduction cavity from different directions, air vortexes are generated in the cavity and counteract one another to a certain extent, energy dissipation of the shock waves is caused, therefore the impact effect on the explosion-proof structure is reduced, the explosion-proof effect of the explosion-proof structure is strengthened, the wave absorbing assembly is of a multi-layer plate-shaped structure and is arranged in the direction deviating from the explosion facing surface, a buffer interlayer absorbsexplosion energy, a supporting layer is a high-strength steel plate, the deformation amount of the explosion-proof structure is reduced, the protection effect is better achieved, and the explosion-proof performance of the explosion-proof structure is further improved.

Description

technical field [0001] The invention relates to the field of explosion-proof walls, in particular to an explosion-proof structure and an explosion-proof wall for offshore platforms. Background technique [0002] Offshore platforms are structures that provide production and living facilities for activities such as drilling, oil production, transportation, observation, navigation, and construction at sea. Due to the limited space of offshore platforms and the dense arrangement of equipment, there are major hidden dangers of oil and gas leakage accidents, which may cause fires and explosions. accidents, resulting in casualties, property damage and environmental pollution and other consequences. [0003] Explosion-proof walls are one of the main measures applied to reduce oil and gas explosion losses on offshore platforms. By setting up explosion-proof walls on platforms, areas with high risk of oil and gas leakage explosions are separated from key protection areas to improve th...

Problems solved by technology

[0004] At present, the explosion-proof walls used in offshore platforms are mainly sandwich plate structures, which rely on the plastic deformation of the interlayer and plates to absorb the impact energy of explosions, but have the disadvantages of large plastic deformation, squeezed space behind the wall, complicated installation and connection construction, and poor anti-blast effects.
