Low-equivalent toxic explosive air bag recovery type explosion-proof structures

Abstract

The invention discloses a low-equivalent toxic explosive airbag recovery type explosion-proof structure. The low-equivalent toxic explosive airbag recovery type explosion-proof structure aims to solve the problem that an explosion-proof structure cannot recover toxic gas generated by explosives, and is composed of a buffer layer, a cylindrical air bag and a fixing mechanism. The buffer layer is composed of an inner buffer pipe, an outer buffer pipe, two foam buffer blocks and a foam interlayer. The inner buffer tube, the outer buffer tube and the foam interlayer form a sandwich structure buffer layer. The cylindrical air bag is made of functional structure materials and is high in tensile strength. The fixing mechanism is composed of two end covers, two clamp suites and four screw assemblies. The cylindrical air bag and the two end covers form a closed space, the buffer layer is wrapped in the closed space, and it is ensured that detonation product gas is stored in the cylindrical air bag when exhausted from the buffer layer. According to the low-equivalent toxic explosive airbag recovery type explosion-proof structure, the flow velocity of detonation products can be reduced, the detonation product gas is guided to be discharged outwards according to a preset route, toxic gas detonation products generated by explosion are collected through expansion of the cylindrical air bag, and pollution of toxic gas to the environment is prevented.

Description

technical field [0001] The invention belongs to an explosion-proof structure, in particular to a low-equivalent toxic explosive air bag recovery type explosion-proof structure. Background technique [0002] Explosives can undergo high-speed chemical reactions under certain external effects, release heat and produce a large number of gas products. For example, after an explosive package is detonated with a detonator, what people see is that the explosive package immediately turns into a ball of fire, releasing a large amount of heat, forming smoke and making a huge noise at the same time. The explosion of explosives has the following three characteristics, namely, the exothermic nature of the reaction, the high speed of the process and the formation of a large number of gas products during the reaction. One of the fundamental reasons why explosives can expand to do work and cause damage to the surrounding medium when explosives explode is that when explosives explode, they c...
