The invention relates to a smoke exhaust system for fire engineering, comprising a smoke detection unit, a temperature detection unit, a smoke exhaust unit, a spray unit, an image acquisition unit and a central control unit. The present invention divides the house into a plurality of detection points by arranging a plurality of smoke detectors, temperature detector smoke exhaust pipes and sprinklers, and independently detects each point, and can independently protect different areas in the house, And when there is an open flame at a certain point, it will be processed separately for this point. At the same time, the central control unit can flexibly adjust the speed of the exhaust fan and the water spray volume of the sprinkler according to the smoke concentration and temperature in the point where the open flame occurs, so as to separately Exhaust smoke and extinguish fire, and activate surrounding exhaust fans and sprinklers when the fire intensity is too high for auxiliary smoke exhaust and fire extinguishing, thereby completing targeted smoke exhaust and fire extinguishing for different fire intensity, and improving the fire fighting efficiency of the system.
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...
