Toxic gas explosion box testing device and testing method thereof

Abstract

The invention discloses a toxic gas explosion box testing device and a testing method thereof. The toxic gas explosion box testing device comprises an explosion box, a mixing mechanism, an collecting and analyzing mechanism and an exhaust mechanism; the explosion box has an explosion chamber, and a carronade for placing a sample is arranged in the explosion chamber; the mixing mechanism comprises a mixing pipeline, both ends of the mixing pipeline are connected with the explosion chamber, and an air compressor and a pneumatic valve are connected to the mixing pipeline; and the gas collecting mechanism comprises a collecting pipeline and a vent valve, and one end of the collecting pipeline communicates with the mixing pipeline. By means of the cooperation of the mixing mechanism, the collecting and analyzing mechanism and the exhaust mechanism, an explosive is exploded under a normal pressure, the test dose can reach 500g TNT equivalent, the charging diameter can reach 100mm, the blank of domestic explosive toxic gas generation amount test is filled, an emulsion explosive is applied to the test, and a scientific means is provided for testing the toxic gas contents of explosives without cap sensitivity.

Description

technical field [0001] The invention relates to the technical field of explosive toxic gas testing equipment, in particular to a toxic gas explosion box testing device and a testing method thereof. Background technique [0002] The toxic gas content of existing industrial explosives tested in China is less than 130g, and the diameter of the charge is not greater than 45mm. It is measured after vacuuming in the cartridge, and the analysis of carbon monoxide and nitrogen oxides is carried out by chemical analysis methods. It can be seen that the existing devices cannot simulate the explosion environment of explosives under normal use conditions, thereby objectively reflecting the content of toxic gases produced after explosive explosions, and cannot meet the test conditions for large-dose, large-diameter charges of explosives without detonator sensitivity. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art ...

AI Technical Summary

Problems solved by technology

It can be seen that the existing devices cannot simulate the explosion environment of explosives under normal use conditions, so as to objectively reflect the content of toxic gases produced after explosive explosions, and cannot meet the test conditions for large-dose, large-diameter charges of explosives without detonator sensitivity.
