Abstract

The invention relates to a device for testing burning and explosion characteristics of a gas phase in a reaction process, and mainly solves problems of low test accuracy and operability and relatively poor trueness in the prior art. The device for testing the burning and explosion characteristics of the gas phase in the reaction process comprises a reactor (1), an ignition head (2), a temperature and pressure sensor (8), a feeding system (3), a temperature and pressure acquisition system (5), an ignition control system (4) and an external circulation heat extraction system (6). Due to the adoption of the technical scheme, the device better solves the problems and can be used for testing the burning and explosion characteristics of the gas phase.

Description

technical field [0001] The invention relates to a device for measuring gas phase combustion and explosion characteristics in the reaction process. Background technique [0002] In the process of chemical production, there are often production processes where flammable gases or volatile flammable liquids coexist with oxidizing gases and abnormal working conditions where air leaks into devices or pipelines containing flammable gases or volatile flammable liquids. Therefore, it is necessary to focus on the study of the explosion characteristics of flammable gases or volatile flammable liquids. [0003] At present, according to relevant test standards, such as "Standard Test Method for Concentration Limits of Flammability of Chemicals (ASTM E681)", "Determination of Explosive Limits of Combustible Gases in Air (GB / T12474)", "Compounds (Steam and Gas) Flammability Standard Test Method for Concentration Limits (GB / T21844)", etc. Conventional detonation characteristics testing dev...
