Smoke exhaust system for fire-fighting engineering

Abstract

The invention relates to a smoke exhaust system for fire-fighting engineering. The smoke exhaust system comprises a smoke detection unit, a temperature detection unit, a smoke exhaust unit, a sprayingunit, an image acquisition unit and a central control unit. By arranging a plurality of smoke detectors, temperature detectors, smoke exhaust pipelines and sprayers, a house is divided into a plurality of detection sites, different areas in the house can be independently protected by independently detecting the sites, the site is independently treated when open fire occurs at a certain site, meanwhile, the central control unit can flexibly adjust the rotating speed of exhaust fans and the water spraying amount of the sprayers according to the smoke concentration and temperature in the open fire site so as to carry out smoke exhausting and fire extinguishing respectively, when the fire behavior is too high, the peripheral exhaust fans and sprayers are started to carry out auxiliary smoke exhausting and auxiliary fire extinguishing, therefore, targeted smoke exhausting and fire extinguishing for different fire behaviors are completed, and the fire-fighting efficiency of the system is improved.

Description

technical field [0001] The invention relates to the technical field of fire-fighting and smoke exhaust, in particular to a smoke exhaust system for fire-fighting engineering. Background technique [0002] With the increasingly tight land resources, people are gradually moving into high-rise buildings to live in. Faced with this phenomenon of group living, the losses caused by fires are also increasing. When a fire occurs, it is not the burning flame that threatens people's lives the most. , but the smoke generated by combustion, so fire smoke exhaust is particularly important; the smoke exhaust effect of the smoke prevention and exhaust system installed in ordinary buildings is very limited, especially when there is a local fire in the building, the smoke exhaust effect is poor, and the common The smoke exhaust system is not equipped with an automatic fire extinguishing device, which cannot reduce the generation of smoke from the source. [0003] The smoke prevention and ex...
