Experiment device and experiment method for gas cloud combustion, explosion simulation and inerting, inhibition

Abstract

The invention relates to the technical field of fire hazard safety, and especially relates to an experiment device and an experiment method for gas cloud combustion, explosion simulation and inerting, inhibition. The device comprises an experiment test system composed of an explosion experiment container tank, a flame and explosion pressure radial propagation detection device, an ignition device, a generated gas sampling analyzer, and a high-speed schlieren and data acquisition, a sample introduction system, a combustion explosion inerting inhibition system, and a control system composed of wireless synchronous control and computer remote monitoring, and is a multifunctional comprehensive experiment platform device. The invention realizes 180-degree rotation of the tank, data synchronous acquisition, gas distribution and sample introduction with precise proportions, synchronous and delayed multimode ignition and inhibition system ejection; wireless and wired data transmission is adopted for control; man-machine separation of the tank and the controlling person is realized; safety and reliability of data transmission are guaranteed; combustion or explosion and inerting and inhibition experiments of various experiment samples such as gas cloud, dust, oil mist, and the like can be carried out when the tank is in a vertical or horizontal state.

Description

technical field [0001] The invention relates to the technical field of fire safety, in particular to an experimental device and experimental method for gas cloud combustion, explosion simulation, inerting and suppression. Background technique [0002] Combustible premixed gas, dust, liquid mist and steam fires and explosion accidents are common types of disaster accidents in petrochemical and other industrial fires and explosion accidents. 1. Explosion suppression technology is a hot spot in the research of industrial fire and explosion prevention technology. At present, people usually use experimental devices such as flame propagation tubes, shock tubes, explosion vessels, or simulated roadways to study the characteristics of combustible gas clouds, dust combustion, and explosions. At present, my country's national standards for dust cloud explosion performance and explosion limit testing and analysis mainly include GB / T16425, GB / T16426 and GB / T12474. The experimental t...
