A composite explosion-proof energy-absorbing device

Abstract

The invention discloses a composite explosion-proof energy-absorbing device, which comprises a surface heat-insulating energy-absorbing layer, a middle electromagnetic anti-explosion layer, a buffer energy-consuming layer and a hydraulic support structure. The surface heat-insulating and energy-absorbing layer includes an upper panel, a lower panel and a sandwich layer. The sandwich layer is made of porous ceramic material, and the upper panel is a composite corrugated board. The outer surface is coated with a high-temperature-resistant fireproof coating. The electromagnetic anti-knock layer is composed of an array of electromagnetic capsules. The buffer energy-dissipating layer includes an upper panel, a lower panel and a sandwich layer structure, the sandwich layer structure is a honeycomb hollow prism, and the honeycomb hollow prism is filled with quartz sand material. The hydraulic support structure includes spring hydraulic support rods, top suspension springs and outer panels. The composite anti-explosion energy-absorbing device provided by the present invention adopts multi-level classification to consume explosion impact load energy, has the advantages of strong anti-explosion ability, high energy absorption efficiency, high temperature resistance and small plastic deformation, and occupies a small space, and can be reused and practical High performance, simple and convenient installation process.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof equipment and relates to a composite explosion-proof energy-absorbing device. Background technique [0002] With the development of economy, countries all over the world have an increasing demand for energy. As an important facility for the exploitation of offshore oil and gas resources, offshore platforms have served in complex and harsh marine environments for a long time. There are many mechanical equipment on the platform, and the internal pipelines and lines of the platform structure are densely arranged, which is prone to fire and explosion accidents. Offshore platforms are typical representatives of high-input, high-risk, and high-yield structures. The platforms store a large amount of oil or natural gas. Once a fire or explosion accident occurs, it will not only cause casualties and major economic losses, but also cause serious damage to the marine environment and marine ecology. ...
