Abstract

The invention relates to the technical field of gas deflagration testing, in particular to a coupling test method and test system for flame and pressure after combustible premixed gas cloud deflagration in an open space with different humidity conditions. The system is composed of a main body part, a gas distributing device, an ignition device, a test device and a computer. The main body part is ahemispheric gas cloud device. The hemispheric gas cloud device is composed of a polyethylene film gas cloud cover, a flame retardant rubber ring plate, and a 16Mn steel ring plate. The gas distributing device is composed of a methane gas cylinder, a compressed air bottle, a calcium chloride container bottle, a humidity sensor, a humidity generator, a heating pipe, a gas premixing tank, a water outlet and a gas flow guide. The test device is composed of a pressure transmitter, a humidity sensor, a temperature sensor, a data collector, a high-speed camera, a high-speed infrared thermal imager and a high-speed schlieren system. The test device is connected with the computer.

Description

technical field [0001] The present invention relates to the test method of deflagration flame and pressure coupling of premixed gas cloud with different humidity in open space and its test system, which relates to the technical field of gas explosion test, and specifically relates to the deflagration flame and pressure of combustible premixed gas cloud in open space under different humidity conditions Coupling test method and its test system. Background technique [0002] When flammable gas accidentally leaks during production, processing, use, transportation and storage, it will form a flammable gas cloud in an open space, and it will explode when it encounters an external fire source with sufficient energy, which is extremely harmful. Since the research on the mechanism and law of combustible gas explosion and the factors affecting combustible gas cloud explosion is not enough, and the vapor cloud explosion will cause great damage, so after the combustible gas cloud explos...
