Powder extinguishing agent dispersion device

The utility model discloses a powder extinguishing agent dispersion device. The device comprises a combustion system, a flame information acquisition system and a powder sieving-off system, wherein the combustion system is composed of a combustion-supporting gas storage device, a flow meter, a flow outlet tube nozzle, a rectifying tube, a rectifying screen, a combustion cup, a fuel flow adjustment valve, a fuel storage device and a windproof cover; the flame information acquisition system is composed of a flame emission spectrum receiving probe, a spectrograph, a camera, a computer, support arms and a lifting mechanism; the powder sieving-off system is composed of a vibration motor, a vibration disc, a connection spring, a shell, a tensioning spring and a powder sieve. The device is characterized in that a powder is uniformly dispersed in the windproof cover in a sieving-off manner, and a spectrum measurement device and the camera with adjustable heights are arranged to explore the interaction principle of a powder extinguishing agent and a combustion flame, thus providing a technical means for deeply researching the mechanism of suppressing and extinguishing the flame of the powder extinguishing agent.
