Abstract

The invention provides a gasbag-type explosion suppression and isolation device and method. The gasbag-type explosion suppression and isolation device and method are applicable to explosion suppression and isolation of gas explosion in a sealed pipeline free of other decompression spaces, and are particularly applicable to explosion suppression and isolation of gas explosion of delivery pipelinesof explosive gases like gas and of coal mine shafts. Firstly, folded gasbags and folded gas generators are installed in pipelines or a roadway, and detectors are installed at the proper positions of the pipelines of the two sides of an explosion suppression and isolation unit. A power source, a control unit and a signal processing system are arranged between the explosion suppression and isolationunit and the detectors in sequence. After explosion feature signals are received by the detectors and judged by a signal processing unit, the power source is started and excites an ignition electrodeto make a gas generator exploded and generate a large amount of inert gas, the inert gas is inflated into the gasbags from diversion pipes and damages a gasbag protection box, the gasbags filled withthe inert gas are instantaneously formed in the pipelines, and propagation of gas explosive shock waves and flame waves is inhibited. By means of the gasbag-type explosion suppression and isolation device and method, the problems in the prior art that only the flame waves can be inhibited and the inhibiting effect is not ideal can be solved.

Description

technical field [0001] The patent of the invention relates to an airbag-type active explosion suppression and explosion-proof method for suppressing gas explosions in coal mines, which is suitable for pipelines for conveying explosive gases such as gas, and also for tunnels where gas explosions occur underground in coal mines. Background technique [0002] In the process of coal mine production, gas explosion accidents seriously threaten the lives of coal miners. Gas explosion disaster is one of the important factors restricting the development of coal industry. With the increase of mine mining depth and intensity, the threat of gas is also increasing, and the problem of gas explosion has become a major problem in coal mine safety and efficient production. In particular, multiple explosions of gas will cause secondary disasters and cause the expansion of accidents. Therefore, the explosion-proof device for coal mine gas has become an important measure to suppress the explo...
