Gas, dust explosion and explosion suppression experiment system applicable to various optical diagnosis methods

Abstract

The invention specifically relates to a gas, dust explosion and explosion suppression experiment system applicable to various optical diagnosis methods, solving the problems of an existing combustible gas, dust explosion and explosion suppression experiment system that the visibility is low, combustible gas explosion/explosion suppression propagation properties only can be tested from a macroscopic level, and application of an advanced optical measurement technology cannot be met. The experiment system comprises an explosion pipeline, a vacuum-pumping system, a gas distribution system, at least two powder spraying systems and an ignition system, and further comprises a planar laser-induced fluorescence system and a main control system. The invention provides the gas, dust explosion and explosion suppression experiment system applicable to the various optical diagnosis methods, which can be combined with a device for disclosing combustion explosion/explosion suppression propagation properties by microcosmic/macroscopic parameters and takes a steel framework and high-light-transmittance quartz glass as a main body structure.

Description

technical field [0001] The invention relates to an explosion suppression experiment system, in particular to a gas and dust explosion and explosion suppression experiment system applicable to multiple optical diagnosis methods. Background technique [0002] Combustion explosion is an important way for human beings to obtain energy. If it occurs in an uncontrolled time and space environment, it will bring huge loss of life and property to people. The explosion of combustible gas is mainly caused by the leakage of combustible gas, which is ignited by the fire source, and gradually forms turbulent combustion, deflagration or even detonation. Because of the huge destructiveness of combustible gas explosions, it is increasingly urgent to study the occurrence mechanism, damage mode and corresponding suppression methods of combustion explosions, and to propose disaster prevention and mitigation measures. Due to the destructiveness and danger of combustible gas explosions, conducti...

AI Technical Summary

Problems solved by technology

Optical combustion diagnosis technology has been widely used in combustion science experiments, but due to the special requirements of its test methods, the existing conventional explosion experimental equipment cannot meet its application conditions, so the application in the diagnosis of explosive transient combustion process is not mature enough

The existing devices still have deficiencies in the light transmission visibility and synchronous measurement and control of the reaction vessel, such as lack of detection window or too small window, low light transmittance, inappropriate installation location, or asynchronous ignition and optical signal measurement and control , a set of devices can only meet the problems of one optical testing technique, etc.

[0006] 1. It can only test the characteristics of combustible gas explosion/suppression propagation process from the macro level, such as the change of parameters such as temperature
