Full-size cabin backdraft simulation experiment device and method

Abstract

The invention provides a full-size cabin backdraft simulation experiment device which comprises a model body, a matched simulation generation device, a measuring and control system and a smoke exhaustdevice; the model body is a simulation cabin formed by an entity steel structure on the basis of the ratio being 1:1; three model storage cabinets are arranged inside the simulation cabin for simulating a storage room conventional cabinet body; the matched simulation generation system comprises a natural gas supply system and an ignition system connected with the natural gas supply system, the natural gas supply system conveys natural gas to gas burners at three model storage cabinets through a natural gas pipeline inside the cabin, and the ignition system comprises ignitors corresponding tothe burners one to one; the measuring and control system comprises a measuring device located at the cabin ceiling for measuring the flue gas temperature; the smoke exhaust system is used for exhausting fire smoke through exhaust holes in the rear wall of the cabin. Teaching demonstrative experiments and fire control fight practical training can be performed, and the device is used for daily firecontrol technology training for firefighting officers, part-time firefighters and related employed persons.

Description

technical field [0001] The invention relates to the technical field of fire simulation, in particular to a full-scale cabin backburning simulation experiment device and an 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. Flashback is a special combustion phenomenon in building fires, and it is common in indoor combustion processes with poor ventilation and sufficient fuel. Examples include combustion in confined spaces. First of all, the combustibles near the fire point will be gradually ignited by the open flame, gradually spread on the surface of the combustibles, and the fire area will gradually expand; and because the fire space is closed, fresh air cannot be replenished into the room smoothly, and the room will gradually become anoxic due to combustion consumption Finall...

AI Technical Summary

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 sufficient understanding of the development law of building fires, especially the special phenomenon of backburning in building fires. is the most threatening, but its own randomness and uncertainty will bring difficulties to fire fighting and rescue
