Full-scale cabin fire spreading and flashover simulation experimental device and experimental method thereof

Abstract

The invention provides a full-scale cabin fire spreading and flashover simulation experimental device, which comprises a model main body, a matched simulation generating device, a temperature measuring system, and a smoke exhausting device. The model main body is a simulation cabin composed solid steel structure with a ratio being 1:1; the cabin is provided with a model bed, a large sofa and a small sofa, all of which are steel structure models, the cabin simulates indoor common furniture, the model bed is located on the left side wall of the cabin, the large sofa is on the back wall, and thesmall sofa is on the front wall; the matched simulation generating device includes a natural gas supply system and an ignition system connected to the natural gas supply system; and the smoke exhausting device is configured to discharge the fire smoke through an exhaust hole of the rear wall of the cabin. The experimental device is used for the simulation experiment of indoor fire spreading and flashover phenomena in daily experimental teaching, can carry out teaching demonstration experiment and fire fighting training, and is used for daily fire-fighting technical training of fire officers and soldiers, part-time firefighters and related practitioners.

Description

technical field [0001] The invention relates to the technical field of fire simulation, in particular to a full-scale cabin fire spread and flashover simulation experiment device and experiment method. Background technique [0002] Fire is a common form of disaster in life. Once a fire occurs, it will directly threaten the safety of people's lives and property. Building fires account for a considerable proportion of all fires. After a local fire in a building, first, the combustibles near the fire point will be gradually ignited by the open flame, and gradually spread on the surface of the combustibles at a certain speed, which is the phenomenon of fire spread. Flashover occurs when there are a lot of combustibles and the ventilation environment is good enough. The occurrence of flashover is the result of a large accumulation of heat released by combustion, which cannot be dissipated immediately within the constraints of the ceiling and surrounding walls. The hot smoke g...

Problems solved by technology

[0003] In the process of actual building fire fighting, rescue and emergency management, relevant practitioners such as active commanders, fire officers and soldiers, and part-time firefighters still lack a full understanding of the development laws of building fires, especially flashover, which is a special building fire phenomenon. is the most threatening, but its own randomness and uncertainty will bring difficulties to fire fighting and rescue
