Abstract

The invention relates to the explosion performance test field of explosive, in particular to a gas concentration detection system capable of working under explosion environment of explosive. The system solves the problem that the gas concentration parameter value under explosion environment of explosive is difficult to obtain currently and comprises a plurality of test points, an analyzer, a gas concentration sensing device; wherein the ground of each test point is opened with a straight flute the two ends of which are covered with a protective cover; the gas concentration sensing device comprises a uniformly distributed lower damping spring underframe and a tuneable diode laser transceiving device and a laser reflecting device which are respectively fixed on the two ends of the underframe, the two devices are all provided with a protective cover outside, the opposite face of the protective covers is provided with a quartz optical window, the underframe is arranged in the straight flute, the lower damping ring is fixed with the bottom of the flute, the two devices are arranged in the protective cover, and the laser transceiving device is connected with the analyzer by an optical fiber and a cable. The invention has reasonable structure, realizes the aim of gas concentration detection under explosion environment of explosive, has good test effect and high accuracy, and provides condition for correct evaluation on explosive performance.

Description

Technical field [0001] The present invention relates to the field of explosive performance testing of explosives (such as detonators, explosives, fireworks and firecrackers, shells, gunpowder, etc.), and is used to obtain the gas concentration at different positions of the explosive explosion site and the relationship curve of the gas concentration with time. It is a gas concentration detection system used in explosive environment of explosives. Background technique [0002] There are many existing gas concentration detection methods, such as infrared spectroscopy, acousto-optic film pressure method, photoionization method, electrochemical method, etc. For the special field of explosive performance testing of explosives, to assess the lethal power of explosives explosion In order to shorten the development cycle and save development costs, it is inevitable to obtain the concentration parameters and concentration changes of the gases (such as oxygen, carbon monoxide gas, etc.) in ...
