Explosion suppression filling material with composite structure

Abstract

The invention relates to an explosion suppression filling material with a composite structure. The explosion suppression filling material is formed by coiling or stacking a plurality of layers of metal foil nets layer by layer, wherein the mesh structures and the mesh directions of the adjacent layers of metal foil nets are different; preferably, the mesh directions of the adjacent layers of metal foil nets are vertical to each other, and the mesh directions of spaced layers of metal foil nets are the same or different; the adjacent layers of metal foil nets are made of different materials; the metal foil nets made of different materials at least comprise metal foil nets made of aluminum alloy materials and / or metal foil nets made of stainless steel alloy materials; and preferably, the outmost layer is provided with a metal foil net which has high intensity, high elasticity and high flexibility. The filling material has a rational structure, and is uniformly supported and stressed and low in collapse deformation; the number of produced crumbles is small; the mounting cost is saved; and the fillimg material is convenient to clean, mount and take out, can be reused, has high comprehensive performance, and can be widely applied to various types of storage tanks and particularly used as filling materials for dangerous cargo transportation truck storage tanks.

Description

technical field [0001] The invention relates to an explosion-suppressing filling material that can be widely used in flammable and explosive liquid (gas) containers, especially suitable for tank trucks transporting dangerous goods, and can fill the blank of explosion-proof materials for tank trucks transporting dangerous goods. Background technique [0002] Inflammable and explosive dangerous goods liquid (gas) containers are filled with explosion-suppressing filling materials according to certain technical requirements, which can effectively suppress and prevent explosions, and prevent container explosions and fires caused by accidents such as open flames, gunshots, lightning strikes, impacts, and static electricity. And it can repair welding operation with liquid and fire.

AI Technical Summary

Problems solved by technology

[0003] At present, the explosion suppression filling materials at home and abroad are basically made of aluminum alloy foil mesh with a single material, a single structure, and a single mesh specification, and there are common problems of easy deformation, collapse, and easy fracture to generate debris.

[0004] Deformation and collapse will easily lead to the formation of an invalid space in the upper part of the liquid (gas) container, which will invalidate the barrier and explosion-proof function, which is very dangerous

In order to solve the problem of subsidence, the common method is to set up angle steel frame support or wire mesh around the container, but these methods reduce the effective volume of the container, increase the manufacturing cost, complex installation and construction, and are not suitable for dynamic load transport tank trucks and vertical storage tanks, so the corresponding users of such containers have to scrap their transport tankers and storage tanks

The generation of debris will easily block the associated pumps, meters, valves and pipelines, seriously affecting the normal operation of the process pipeline system and the normal regular inspection and cleaning of the container. The maintenance cost is high, and the explosion suppression material can only be used Disposable use, use cost is also high
