Abstract

The invention discloses a combustible gas explosion feature experiment system in ultralow temperature environment. The combustible gas explosion feature experiment system comprises an explosion tank body, a temperature reducing system, a data collecting system, an ignition system and a gas distribution system, wherein the temperature reducing system is covered on the explosion tank body, and the data collecting system is provided with a thermal resistance and pressure sensor which are arranged in the explosion tank body, and a data collecting device. When the system is used for measuring the combustible gas explosion feature parameters in the ultralow temperature environment, firstly, the explosion tank body is pumped into a vacuum state, then, combustible gas to be tested is inflated into the explosion tank body, in addition, the temperature reduction is carried out, finally, the combustible gas to be tested is ignited, in addition, explosion feature parameter data in the explosion tank body is collected, and the explosion feature parameter data is stored. The combustible gas explosion feature experiment system provided by the invention has the advantages that by aiming at coal bed gas, a deep cold liquification process is utilized for testing the combustible gas explosion limit in the ultralow temperature environment, and the test and experiment research work on parameters of ultralow temperature environment combustible gas explosion pressure and pressure rising velocity and the like can also be carried out.

Description

technical field [0001] The invention relates to the field of industrial safety, in particular to a system for measuring the characteristic parameters of combustible gas explosion limits under ultra-low temperature environment conditions that can be directly used in industrial production processes. Background technique [0002] At present, there are no standards at home and abroad on the experimental research on the explosive characteristics of combustible gases in special environments. In my country, there is only the national standard of the People's Republic of China. Method for determination of explosion limit of combustible gas under normal temperature and pressure conditions. However, there is still a lack of corresponding technical means for the determination of the explosion limit of flammable gases in ultra-low temperature (below 0°C) environments. At present, although some scientific research institutes in my country have relevant equipment for the study of the expl...
