Research method of ultralow temperature gas explosion experiment under ultralow temperature environment

Abstract

The invention discloses a research method of an ultralow temperature gas explosion experiment under an ultralow temperature environment. The research method comprises the following steps: firstly, vacuumizing an exploding tank; secondly, charging a combustible gas to be detected into the exploding tank and cooling; and finally, igniting the combustible gas to be detected, and acquiring and storing the explosion characteristic parameter data in the exploding tank. The research method has the following advantages: aiming at the research method of the ultralow temperature gas explosion experiment under the ultralow temperature environment, the problem that an ultralow temperature gas explosion experiment method can be carried out under the ultralow temperature environment is mainly solved; and aiming at detecting explosion limit of the combustible gas under the ultralow temperature environment, detection and experiment research work for the parameters of the combustible gas under the ultralow temperature environment, such as exploding pressure and pressure ascent rate and the like. The research method of the ultralow temperature gas explosion experiment under the ultralow temperature environment mainly aims at detecting the explosion limit of coal bed methane under the ultralow temperature environment by a cryogenic liquefying process and detecting the exploding characteristic parameters of other industrial combustible gases under the ultralow temperature environment.

Description

technical field [0001] The invention relates to the field of industrial safety, in particular to an experimental research method that can be directly used in the determination of characteristic parameters such as the explosion limit of combustible gas under ultra-low temperature environmental conditions in the industrial production process. 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 ...

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 explosion characteristics of combustible gases in high-temperature or high-pressure environments, they cannot realize the research on the explosion characteristics of combustible gases in ultra-low temperature environments.
