Abstract

The invention provides a multi-window multifunctional gas and dust explosion inhibition experiment system, and aims to meet a high-transparency quartz window characterized in that a plurality of external triggering connectors are available for externally connecting devices and a plurality of advanced optical testers are synchronously used, and to achieve a comprehensive explosion experiment testing system for preparing multiple gases. The multi-window multifunctional gas and dust explosion inhibition experiment system comprises a testing control system, an explosion container, an ignition system, a gas distribution system, a powder spraying system, a vacuuming system, a heating constant-temperature system as well as at least two optical diagnosis windows, an ignition external triggering connector and a powder spraying external triggering connector, wherein the ignition system is connected with the explosion container; the optical diagnosis windows are formed in side surfaces of the explosion container; the ignition external triggering connector is arranged on an energy-adjustable high-pressure pulse igniter; the powder spraying external triggering connector is arranged on a system testing and control main machine.

Description

technical field [0001] The invention relates to a gas and dust explosion suppression experiment system, in particular to a multi-window multifunctional gas and dust explosion suppression experiment system. Background technique [0002] In industrial production, the external environment where combustible gas and dust are located is often not normal temperature and pressure, and multi-component mixed gas and dust explosions are very common, and the situations of explosions are complex and changeable. At present, in the field of gas and dust explosion research at home and abroad, there are many experimental studies using 20L spherical systems, and the explosion test parameters of 20L spherical reaction vessels are relatively recognized, but most of the existing 20L spherical systems are standard gas and dust explosion test systems In China, only Chongqing Academy of Coal Sciences, North University of China and other units have self-made 20L spherical explosion experimental syst...
