The invention belongs to the technical field of combustible gas explosion safety, relates to a fire resistance performance test and detection protection device for a visual hydrogen explosion corrugated flame arrester, particularly to an experimental device for fire resistance and explosion suppression related theoretical research in a hydrogen and air premixed gas explosion process and a device for detecting the fire resistance performance of a flame arrester. The device comprises a detonation section pipeline, a protection section pipeline, a high-frequency response explosion suppression system, a hydrogen premixing and distributing system, a flame accelerating device, a flame arresting core temperature collecting system, a slit flame propagation testing system, a high-frequency pressure and temperature collecting system, a flame propagation speed collecting system, and an explosion flow field structure and flame form acquisition system, wherein the detonation section pipeline and the protection section pipeline are connected to the two ends of a visual flame arresting system. The flame propagation speed of flames entering the flame arrester is regulated and controlled through ignition energy and the flame accelerating device, control and data acquisition of ignition, explosion resistance and explosion suppression are achieved through a synchronous controller and a program control and data acquisition system, and the fire resistance performance of the flame arrester and the explosion suppression efficiency of a high-frequency response explosion suppression system are evaluated from multiple perspectives.

Description

technical field [0001] The invention belongs to the technical field of combustible gas explosion safety, and specifically relates to an experimental device for theoretical research on flame arresting and explosion suppression in the explosion process of hydrogen and air premixed gas, and a device for detecting the flame arresting performance of a flame arrester. Background technique [0002] In the middle of the last century, developed countries gradually carried out hydrogen energy industry research. At present, the development of my country's hydrogen energy industry has entered a blowout period. As a highly active clean energy, hydrogen is widely used in industrial production, and it has attracted much attention because of its characteristics of being extremely prone to combustion and explosion. Hydrogen flame arresters have been widely used in hydrogen storage tanks and transportation pipeline factories, urban pipe network systems, hydrogen refueling stations and other i...

AI Technical Summary

Problems solved by technology

Photosensitive sensors or flame sensors are often used to detect flame signals to judge the flame arrester's flame arresting performance, but this method is prone to misjudgment or untimely response

In addition, most detection devices and methods have not effectively measured the characteristics of flame propagation inside the flame arrester, and have not effectively measured the temperature change characteristics of the flame arrester before and after the flame arrest, thus lacking a comprehensive analysis and evaluation of the flame arrester characteristics

No effective protection has been taken for the failure of fire arresting in the test
