Abstract

The application provides a backdraft explosion simulation device for fire training, and belongs to the technical field of simulation devices. The device specifically comprises a box body, a spraying system, an ignition system, a telemetry system, a control system, a supply system and a feeding system. One of the supply system and the feeding system shares an oil tank, an oil pump and a flame arrester, and is finally separated from a pipe tee to an oil atomizing nozzle. The feeding system comprises an oil path and a gas path. The gas path comprises a manual valve, a flame arrester, an electromagnetic valve, a combustible gas tank and a pipe. The device has a simple structure, is convenient to operate, and further reduces pollution.
